Objective: High disease activity status (HDAS) in patients with systemic lupus erythematosus (SLE) is associated with adverse long-term outcomes. We examined the frequency of lupus low disease activity state (LLDAS) and remission (REM) attainment in HDAS patients and whether their attainment was associated with improved patient outcomes., Methods: Demographic, clinical and outcomes data, collected prospectively from a multinational cohort between 2013 and 2020, were analysed. Disease activity was assessed using SLEDAI-2K. HDAS was defined as SLEDAI-2K ≥ 10. Patients' first visit with SLEDAI-2K ≥ 10 was assigned as baseline. Survival analyses were performed to examine the associations between cumulative and sustained LLDAS and REM attainment in HDAS patients and subsequent organ damage accrual and flare., Results: 1,029 HDAS patients with a median study duration of 2.7 years [IQR: 1.0, 4.8] were studied. LLDAS and REM were attained at least once by 71% (LLDAS-ever, n = 726) and 41% (REM-ever, n = 418) of patients. Approximately one-fifth of patients attained ≥50% cumulative time in LLDAS or REM. 37% (n = 385) of patients attained ≥3months of sustained LLDAS, with progressively lower proportions of patients attaining longer periods of sustained LLDAS. Lower proportions of patients attained sustained REM. Attainment of cumulative and sustained LLDAS or REM provided significant protection against damage accrual and flare in HDAS patients. Sustained periods of LLDAS and REM were difficult to achieve and therefore a more stringent target, but provided the most protection against damage accrual or flare., Conclusion: LLDAS and REM were achievable targets in HDAS patients, and provided significant protection against adverse outcomes., (© The Author(s) 2024.

Objectives: To compare adverse events and flares among different doses and types of COVID-19 vaccines in patients with systemic lupus erythematosus (SLE)., Methods: All consecutive SLE patients in a lupus cohort, seen between March and October 2022, were invited to join this retrospective study. Inclusion criteria were aged ≥ 20 years and had received at least one dose of COVID-19 vaccine. Data regarding adverse events after vaccination, clinical disease activity and flares within 30 days postvaccination were reviewed., Results: A total of 201 SLE patients received 524 vaccine doses, with 201, 199, and 124 patients received 1, 2, and 3 doses, respectively. The vaccines included inactivated virus vaccine, adenovirus-vectored vaccine, and mRNA vaccines in 183 (35%), 128 (24%), and 213 (41%) doses, respectively. Regardless of the dose and type of vaccine, adverse events occurred in 50%-70% of patients. Pain and swelling at the injection site were common local symptoms, whereas constitutional, neurological, musculoskeletal, and mucocutaneous symptoms were among systemic ones. The majority of these symptoms were mild to moderate. Patients reported they had disease flares after vaccination in 5%-6%, while actual flares determined by physicians occurred in 8%-13% of them, giving fair to moderate rating agreement between patients and physicians (Cohen's kappa: 0.21-0.44). There was no significant difference in mean mSLEDAI-2K between pre- and 30 days postvaccination., Conclusions: Adverse events after vaccination were common, regardless of the dose or type of COVID-19 vaccines, but only a small proportion of patients had severe symptoms. Flares were uncommon. The rating agreement of flares between patients and physicians as fair to moderate., (© 2024 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.)

Objectives: To determine the spectrum, clinical features and outcomes in systemic lupus erythematosus (SLE) patients with acute abdominal pain (AAP)., Method: Medical records of SLE patients in a lupus cohort from January 1987 to June 2023 were reviewed. Patients with AAP requiring hospitalization were identified and categorized into 3 groups: lupus mesenteric vasculitis (LMV), non-LMV, and surgical AAP. Each AAP episode represented one patient., Results: Of 1,538 patients in the cohort, 62 (4.03%) had 93 episodes of AAP. After exclusion, 31 patients had 39 LMV episodes, and 30 had 40 non-LMV episodes (19 due to surgical AAP). Seventy-six of the 79 AAP episodes (96.20%) were in females, with a mean ± SD age and median (IQR) disease duration of 36.76 ± 13.60 years and 6 (2, 9) years, respectively. Patients in the LMV group had more fever, nausea and vomiting, and diarrhea than those in the non-LMV group. They also had more small bowel involvement, bowel wall thickening, target water enhancement signs, mesenteric vessels engorgement and mesenteric fat cloudiness, and higher SLE disease activity. These differences were more pronounced when compared to the surgical AAP group. Treatment with corticosteroids and immunosuppressive drugs gave favorable outcomes in the LMV group. Two of 40 (5.00%) non-LMV AAP patients died, of which 1 (5.26%) was in the surgical AAP group., Conclusion: LMV was common among SLE patients admitted for AAP. LMV usually presented with fever, gastrointestinal dysmotility symptoms, diffused abdominal pain, together with evidence of active disease. Localized abdominal pain with peritoneal signs favored surgical AAP. Key Points • Lupus mesenteric vasculitis is common among SLE patients presenting with acute abdominal pain. Its presence often associates with gastrointestinal symptoms together with other clinical manifestations of SLE • The signs in abdominal computed tomography findings are not specific and could be observed in other causes of abdominal pain in SLE. Interpretation of these signs should be cautionary and accompanied by history taking and physical abdominal findings • Treatment of lupus mesenteric vasculitis with corticosteroids alone, or in combination with immunosuppressive drugs, usually results in good outcomes., Competing Interests: Declarations.

Objectives: The lupus low disease activity state (LLDAS) allows for certain clinical and/or serological activity of SLE, provided overall disease activity does not exceed predefined cut-offs. This study aimed to evaluate the outcomes of patients who achieved LLDAS with clinical activity, serological activity only or neither clinical nor serological activity., Methods: Patients with SLE enrolled in a prospective multinational cohort from March 2013 to December 2020 who were in LLDAS at least once were included. Visits that fulfilled both LLDAS and Definition of Remission in SLE (DORIS) criteria were excluded., Results: 2099 patients were included, with median follow-up of 3.5 (IQR 1.3-5.8) years. At 6150 visits, patients were in LLDAS but not DORIS criteria; of these 1280 (20.8%) had some clinical activity, 3102 (50.4%) visits had serological activity only and 1768 (28.8%) visits had neither clinical nor serological activity. Multivariable regression analysis showed that compared with non-LLDAS, all three subsets of LLDAS had a protective association with flares in the ensuing 6 months and damage accrual in the ensuing 36 months. LLDAS with no clinical or serological activity had a significantly stronger protective association with severe flares in the ensuing 6 months compared with LLDAS with clinical activity (HR 0.47, 95% CI (0.27 to 0.82), p=0.007)., Conclusions: LLDAS without any clinical activity accounted for almost 80% of LLDAS visits. This study confirms that all subsets of LLDAS are associated with reduced flare and damage accrual. However, LLDAS without any clinical or serological activity has the strongest protective association with severe flares., Competing Interests: Competing interests: SO'N received consulting fees from AstraZeneca, Biogen, Boehringer Ingelheim; lecture/speaker fees from AstraZeneca, Biogen, Boehringer Ingelheim, Pfizer and GSK and research grants from Aurania, Biogen, Idorsia, Novartis.

Background: Validation of protective associations of the lupus low disease activity state (LLDAS) against flare, irreversible damage, health-related quality of life, and mortality has enabled the adoption of treat-to-target strategies in patients with systemic lupus erythematosus (SLE). Previous validation studies were of short duration, limiting the ability to detect longer term signals in flare rate and irreversible damage. In addition, previous studies have focused on percent time at target, rather than actual periods of time that are more useful in clinical practice and trials. We assessed long-term protective associations of LLDAS and remission, and specifically examined protective thresholds of sustained LLDAS and remission., Methods: Patients aged 18 years or older with SLE were followed up from May 1, 2013, to Dec 31, 2020 in a prospective, multinational, longitudinal cohort study. Patients were recruited from 25 centres in 12 countries. Multi-failure time-to-event analyses were used to assess the effect of sustained LLDAS on irreversible damage accrual (primary outcome; measured with the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index) and flare (key secondary outcome; measured with the SELENA Flare Index), with dose exposure and threshold effects studied. Sustained LLDAS or remission were defined as two or more consecutive visits over at least 3 months in the respective state. This study is registered with ClinicalTrials.gov, NCT03138941., Findings: 3449 patients were followed up for a median of 2·8 years (IQR 1·1-5·6), totalling 37 662 visits. 3180 (92·2%) patients were women, and 3031 (87·9%) were of Asian ethnicity. 2506 (72·7%) patients had sustained LLDAS at least once. Any duration of sustained LLDAS or remission longer than 3 months was associated with reduced damage accrual (LLDAS: hazard ratio 0·60 [95% CI 0·51-0·71], p<0·0001; remission: 0·66 [0·57-0·76], p<0·0001) and flare (LLDAS: 0·56 [0·51-0·63], p<0·0001; remission: 0·66 [0·60-0·73], p<0·0001), and increasing durations of sustained LLDAS corresponded to increased protective associations. Sustained DORIS remission or steroid-free remission were less attainable than LLDAS., Interpretation: We observed significant protective associations of LLDAS and remission against damage accrual and flare, establish a threshold of 3 months sustained LLDAS or remission as protective, and demonstrate deepening protection with longer durations of sustained LLDAS or remission., Funding: The Asia Pacific Lupus Collaboration receives project support grants from AstraZeneca, Bristol Myers Squibb, EMD Sereno, GSK, Janssen, Eli Lilly, and UCB., Competing Interests: Declaration of interests RK-R received grants from GSK and Novartis.

Objective: To assess whether Lupus Low Disease Activity State (LLDAS) attainment is associated with favorable outcomes in patients with recent onset systemic lupus erythematosus (SLE)., Methods: Data from a 13-country longitudinal SLE cohort were collected prospectively between 2013 and 2020. An inception cohort was defined based on disease duration < 1 year at enrollment. Patient characteristics between inception and noninception cohorts were compared. Survival analyses were performed to examine the association between LLDAS attainment and damage accrual and flare., Results: Of the total 4106 patients, 680 (16.6%) were recruited within 1 year of SLE diagnosis (inception cohort). Compared to the noninception cohort, inception cohort patients were significantly younger, had higher disease activity, and used more glucocorticoids, but had less organ damage at enrollment. Significantly fewer inception cohort patients were in LLDAS at enrollment than the noninception cohort (29.6% vs 52.3%, P < 0.001), but three-quarters of both groups achieved LLDAS at least once during follow-up. Limiting analysis only to patients not in LLDAS at enrollment, inception cohort patients were 60% more likely to attain LLDAS (hazard ratio 1.37, 95% CI 1.16-1.61, P < 0.001) than noninception cohort patients and attained LLDAS significantly faster. LLDAS attainment was significantly protective against flare in both the inception and noninception cohorts. A total of 88 (13.6%) inception cohort patients accrued organ damage during a median 2.2 years of follow-up., Conclusion: LLDAS attainment is protective from flare in recent onset SLE. Significant protection from damage accrual was not observed because of low rates of damage accrual in the first years after SLE diagnosis.

Objectives: To assess the risk of flare and damage accrual after tapering glucocorticoids (GCs) in modified serologically active clinically quiescent (mSACQ) patients with systemic lupus erythematosus (SLE)., Methods: Data from a 12-country longitudinal SLE cohort, collected prospectively between 2013 and 2020, were analysed. SLE patients with mSACQ defined as the state with serological activity (increased anti-dsDNA and/or hypocomplementemia) but without clinical activity, treated with ≤7.5 mg/day of prednisolone-equivalent GCs and not-considering duration, were studied. The risk of subsequent flare or damage accrual per 1 mg decrease of prednisolone was assessed using Cox proportional hazard models while adjusting for confounders. Observation periods were 2 years and censored if each event occurred., Results: Data from 1850 mSACQ patients were analysed: 742, 271 and 180 patients experienced overall flare, severe flare and damage accrual, respectively. Tapering GCs by 1 mg/day of prednisolone was not associated with increased risk of overall or severe flare: adjusted HRs 1.02 (95% CI, 0.99 to 1.05) and 0.98 (95% CI, 0.96 to 1.004), respectively. Antimalarial use was associated with decreased flare risk. Tapering GCs was associated with decreased risk of damage accrual (adjusted HR 0.96, 95% CI, 0.93 to 0.99) in the patients whose initial prednisolone dosages were >5 mg/day., Conclusions: In mSACQ patients, tapering GCs was not associated with increased flare risk. Antimalarial use was associated with decreased flare risk. Tapering GCs protected mSACQ patients treated with >5 mg/day of prednisolone against damage accrual. These findings suggest that cautious GC tapering is feasible and can reduce GC use in mSACQ patients., Competing Interests: Competing interests: YK received honoraria from Asahi Kasei Pharma, Astellas Pharma, AstraZeneca K.K., Chugai Pharmaceutical, GlaxoSmithKline KK, Janssen Pharmaceutical KK, Mitsubishi Tanabe Pharma Corporation, Pfizer Japan, Sanofi KK.

This study aimed to clarify the association of HLA Class I and II with dcSSc and lcSSc in Thais. HLA typing for 11 gene loci (Class I: HLA-A, B and C, and Class II [HLA-DR, DP and DQ]) was carried out using the Next Generation DNA Sequencing method (three fields) in 92 Thai patients with systemic sclerosis (55 dcSSc, 37 lcSSc) and 135 healthy controls (HCs). The distribution of HLA alleles in patients with dcSSc and lcSSc was compared. When compared with HCs, the AF of A*24:02:01 , A*24:07:01 , B*27:04:01 and B*27:06 showed an increasing trend in lcSSc patients without statistical significance. DRB1*15:02:01 , DRB5*01:02:01 , DQA1*01:01:01 , DQB1*05:01:24 , DPA1*02:01:01 and DPB1*13:01:01 increased significantly in dcSSc patients. DQB1*05:01:24 and DPB1*13:01:01 also increased significantly in lcSSc patients, but less significantly than in dcSSc patients. The association of DPB1*05:01:01 with lcSSc was significantly protective. HLA-A*24:02:01 , B*27:06 and C*03:04:01 formed a three-locus haplotype that also constituted an eight-locus haplotype with DRB1*15:02:01 , DQA1*01:01:01 , DQB1*05:01:24 , DPA1*02:01:01 and DPB1*13:01:01 . There was a possibility that HLA Class I would play a role in the pathogenesis of lcSSc, while Class II played more of a role in the dcSSc in Thai patients.

Introduction: Hyperuricemia is a common complication of hematologic malignancies, and hyperuricosuria in this population has shown conflicting results. This study aimed to determine the prevalence of hyperuricemia and parameters associated with serum uric acid (SUA) and urine uric acid (UUA) in patients with lymphoma and myeloproliferative neoplasms (MPN)., Methods: This cross-sectional study included adult patients with newly diagnosed lymphoma and MPN at the university-based hospital. Clinical characteristics were collected, and independent risk factors for hyperuricemia and hyperuricosuria were determined using multiple logistic regression., Results: One hundred and sixty-five patients were included with a median age of 55 years (45.5-64) and 51.5% were males. There were 91 patients (55.2%) with lymphoma and 74 cases (44.8%) of MPN. Overall, hyperuricemia was prevalent in 43.6% with a median SUA of 6.3 mg/dl (4.6-8) and hyperuricosuria was detected in 39.4% with a median 24-h UUA of 545 mg (365.4-991). Hyperuricemia was observed in patients with lymphoma and MPN in 20.9% and 71.6%, respectively, and hyperuricosuria in 15.4% and 68.9%, respectively. In lymphoma patients, estimated glomerular filtration rate (eGFR) <90 ml/min/1.73 m 2 and serum lactate dehydrogenase (LDH) ≥ 250 U/L were associated with hyperuricemia with odds ratio (OR) 3.24, 95% confidence interval (CI) 1.95-11.07, p = 0.006 and OR 2.07, 95%CI 1.62-6.97, p = 0.039), and only elevated serum LDH was related to hyperuricosuria (OR 2.37, 95%CI 1.56-14.29, p = 0.036). In MPN patients, hemoglobin levels <10 g/dl and serum LDH ≥ 640 mg/dl were independent risk factors of hyperuricosuria (OR 1.88, 95%CI 1.42-8.39, p = 0.045 and OR 6.21, 95%CI 1.49-25.74, p = 0.012)., Conclusion: Hyperuricemia in patients with hematologic malignancies was common, notably MPN, and parameters associated with hyperuricosuria were provided. In addition to the utilization of allopurinol in patients at high risk of tumor lysis syndrome, patients without hyperuricosuria may also be of significant interest., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Kunlayawutipong, Rattanathammethee, Punnachet, Hantrakun, Piriyakhuntorn, Hantrakool, Chai-Adisaksopha, Rattarittamrong, Tantiworawit, Norasetthada and Louthrenoo.)

Background: This study examines the association of standard-of-care systemic lupus erythematosus (SLE) medications with key outcomes such as low disease activity attainment, flares, damage accrual, and steroid-sparing, for which there is current paucity of data., Methods: The Asia Pacific Lupus Collaboration (APLC) prospectively collects data across numerous sites regarding demographic and disease characteristics, medication use, and lupus outcomes. Using propensity score methods and panel logistic regression models, we determined the association between lupus medications and outcomes., Results: Among 1707 patients followed over 12,689 visits for a median of 2.19 years, 1332 (78.03%) patients achieved the Lupus Low Disease Activity State (LLDAS), 976 (57.18%) experienced flares, and on most visits patients were taking an anti-malarial (69.86%) or immunosuppressive drug (76.37%). Prednisolone, hydroxychloroquine and azathioprine were utilised with similar frequency across all organ domains; methotrexate for musculoskeletal activity. There were differences in medication utilisation between countries, with hydroxychloroquine less frequently, and calcineurin inhibitors more frequently, used in Japan. More patients taking leflunomide, methotrexate, chloroquine/hydroxychloroquine, azathioprine, and mycophenolate mofetil/mycophenolic acid were taking ≤ 7.5 mg/day of prednisolone (compared to > 7.5 mg/day) suggesting a steroid-sparing effect. Patients taking tacrolimus were more likely (Odds Ratio [95% Confidence Interval] 13.58 [2.23-82.78], p = 0.005) to attain LLDAS. Patients taking azathioprine (OR 0.67 [0.53-0.86], p = 0.001) and methotrexate (OR 0.68 [0.47-0.98], p = 0.038) were less likely to attain LLDAS. Patients taking mycophenolate mofetil were less likely to experience a flare (OR 0.79 [0.64-0.97], p = 0.025). None of the drugs was associated with a reduction in damage accrual., Conclusions: This study suggests a steroid-sparing benefit for most commonly used standard of care immunosuppressants used in SLE treatment, some of which were associated with an increased likelihood of attaining LLDAS, or reduced incidence of flares. It also highlights the unmet need for effective treatments in lupus., (© 2024. The Author(s).)

Background/objective: To determine the prevalence of thyroid dysfunctions and thyroid autoantibodies in Thai systemic lupus erythematosus (SLE) patients, and compare them with age- and sex-matched healthy controls (HCs). Associations between thyroid dysfunctions and SLE disease activity, and associated factors for thyroid dysfunctions in SLE also were determined., Method: One hundred SLE patients, without apparent clinical thyroid disease, attended the Rheumatology Clinic between November 2021 and October 2022, were enrolled into this study. HCs were matched to SLE cases by age and sex (ratio of 1:1). Clinical manifestations, SLE disease activity and medication received were collected in all SLE patients. Thyroid function tests and thyroid autoantibodies (anti-thyroglobulin: anti-TG and anti-thyroid peroxidase: anti-TPO) were collected from all participants., Results: When compared with HCs, SLE patients had higher prevalence of thyroid dysfunctions, hypothyroidism and euthyroid sick syndrome (28% vs. 7%, p < .001, and 12% vs. 2%, p = .010, and 6% vs. 0%, p = .013, respectively). Prevalence of isolated hypothyroxinemia was higher numerically in SLE patients (9% vs. 3%, p = .074). Prevalence of anti-TG or anti-TPO was no different between SLE patients and HCs (16% vs. 18%, p = .707). There was no association between SLE disease activity and abnormal thyroid functions or thyroid autoantibodies. Family history of thyroid disease and prednisolone use (>10 mg/day) were associated factors for thyroid abnormalities with adjusted OR (95% CI) of 6.13 (1.58-23.75), p = .009 and 4.00 (1.37-11.70), p = .011, respectively., Conclusion: Thyroid dysfunctions were more prevalent in SLE patients. Family history of thyroid disease and prednisolone use (>10 mg/day) were independent associated factors of thyroid abnormalities., (© 2024 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.)

Background: Studies have found that late-onset systemic lupus erythematosus (SLE) patients (age at diagnosis ≥ 50 years) had less severe disease and milder clinical course, but with higher organ damage and mortality rate than early-onset ones (age at diagnosis < 50 years). Unfortunately, direct comparison of renal manifestations and treatment outcomes between late- and early-onset SLE patients has been determined rarely. This study aimed to compare lupus nephritis (LN) manifestations, treatment, and outcomes between late- and early-onset in SLE patients., Methods: Medical records of SLE patients in a lupus cohort at a tertiary care university hospital, seen between January 1994 and June 2020, were reviewed. Late- and early-onset patients were matched with year at SLE diagnosis at a ratio of 1:2 (62 and 124 patients, respectively). Those with LN were identified and analyzed., Results: At SLE onset and end of the study, LN was identified in 29 and 33 late-onset patients, respectively, and 58 and 90 early-onset patients, respectively. At the end of the study, there were 39 and 214 LN flares in late- and early-onset patients, respectively: giving an incident rate (IR) (95% confidence interval (CI))/100 person-years of LN and active LN flares of 2.00 (0.75 - 5.33) vs. 6.11 (4.32 - 8.64), P = 0.020, and 5.78 (2.75 - 12.12) vs. 18.28 (13.93 - 24.00), P = 0.001, respectively. Late-onset patients received a higher proportion of moderate- to high-dose corticosteroids, but fewer immunosuppressive drugs. In all LN flares, no difference existed between the two groups in serum creatinine, degree of proteinuria, and proportion of patients with nephrotic range proteinuria or rapidly progressive glomerulonephritis, and outcomes in terms of complete, partial or no-remission were similar between them. Mortality rate was higher in late-onset patients (27.27% vs. 6.67%, P = 0.004)., Conclusion: This matched controlled study of year at SLE diagnosis showed that late-onset SLE patients had lower prevalence of LN and LN flares. Although they received fewer immunosuppressive drugs, their renal manifestations and treatment outcomes were no different from those in early-onset patients., Competing Interests: The authors declare no conflict of interest., (Copyright 2024, Mongkolchaiarunya et al.)

Objective: Disease activity monitoring in SLE includes serial measurement of anti-double stranded-DNA (dsDNA) antibodies, but in patients who are persistently anti-dsDNA positive, the utility of repeated measurement is unclear. We investigated the usefulness of serial anti-dsDNA testing in predicting flare in SLE patients who are persistently anti-dsDNA positive., Methods: Data were analysed from patients in a multinational longitudinal cohort with known anti-dsDNA results from 2013 to 2021. Patients were categorized based on their anti-dsDNA results as persistently negative, fluctuating or persistently positive. Cox regression models were used to examine longitudinal associations of anti-dsDNA results with flare., Results: Data from 37 582 visits of 3484 patients were analysed. Of the patients 1029 (29.5%) had persistently positive anti-dsDNA and 1195 (34.3%) had fluctuating results. Anti-dsDNA expressed as a ratio to the normal cut-off was associated with the risk of subsequent flare, including in the persistently positive cohort (adjusted hazard ratio [HR] 1.56; 95% CI: 1.30, 1.87; P < 0.001) and fluctuating cohort (adjusted HR 1.46; 95% CI: 1.28, 1.66), both for a ratio >3. Both increases and decreases in anti-dsDNA more than 2-fold compared with the previous visit were associated with increased risk of flare in the fluctuating cohort (adjusted HR 1.33; 95% CI: 1.08, 1.65; P = 0.008) and the persistently positive cohort (adjusted HR 1.36; 95% CI: 1.08, 1.71; P = 0.009)., Conclusion: Absolute value and change in anti-dsDNA titres predict flares, including in persistently anti-dsDNA positive patients. This indicates that repeat monitoring of dsDNA has value in routine testing., (© The Author(s) 2023. Published by Oxford University Press on behalf of the British Society for Rheumatology.)

Introduction: This study aimed to compare the efficacy of non-loading versus loading low-dose colchicine in patients with acute crystal-associated arthritis., Materials and Methods: All in-patients who were admitted to Chiang Mai University Hospital with non-arthritis disease and developed acute crystal-associated arthritis during admission (within 48 h after arthritis onset) were invited to join this study. The patients were randomized into two groups. Patients in Group I (non-loading group) and Group II (loading group) received colchicine at 1.2 and 2.4 mg in the first 24 h, respectively. The primary outcome was the patients' pain response at 24 h after treatment., Results: Of 80 patients, 49 were acute gouty arthritis, and 31 acute calcium pyrophosphate (CPP) arthritis. The mean [95% CI] pain score was no different between Groups I and II at the baseline level (6.46[5.72-7.19] vs. 6.654[5.85-7.44], p = .867) and at 24 h (3.13[2.43-3.82] vs. 3.18[2.42-3.93], p = .907). The proportion of patients with ≥50% pain reduction was not different (57.50% vs. 55.00%, p = .822). Sensitivity analysis among patients with a baseline pain score of ≥4 showed the same pattern of response. Mild diarrhea was common and comparable in both groups. Subgroup analysis according to renal function (eGFR < 60 vs. ≥60 mL/min/1.73 m 2 ) or type of crystals (acute gouty arthritis vs. acute CPP arthritis) also showed the same pattern of response., Conclusion: Non-loading low-dose colchicine was as effective as loading low-dose colchicine in patients with acute crystal-associated arthritis, regardless of renal function or type of crystals., (© 2023 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.)

Background: Targets of treatment for systemic lupus erythematosus (SLE) include the Lupus Low Disease Activity State (LLDAS), remission, and complete remission. Whether treatment can be tapered after attaining these targets and whether tapering is safer in patients in complete remission compared with LLDAS are unknown. We aimed to assess the odds of disease flares after treatment tapering in stable disease, versus continuing the same therapy. We also aimed to examine whether tapering in complete remission resulted in fewer flares or longer time to flare compared with tapering in LLDAS or remission., Methods: This multinational cohort study was conducted at 25 sites across 13 Asia-Pacific countries. We included adult patients aged 18 years or older with stable SLE who were receiving routine clinical care, had two or more visits and had attained stable disease at one or more visits. We categorised stable disease into: LLDAS (Systemic Lupus Erythematosus Disease Activity Index 2000 [SLEDAI-2K] score ≤4, Physician Global Assessment [PGA] ≤1, and prednisolone ≤7·5 mg/day); Definitions of Remission in SLE (DORIS) remission (clinical SLEDAI-2K score 0, PGA <0·5, and prednisolone ≤5 mg/day); or complete remission on therapy (SLEDAI-2K score 0, PGA <0·5, and prednisolone ≤5 mg/day). Stable disease categories were mutually exclusive. Tapering was defined as any decrease in dose of corticosteroids or immunosuppressive therapy (mycophenolate mofetil, calcineurin inhibitors, azathioprine, leflunomide, or methotrexate). Using multivariable generalised estimating equations, we compared flares (SELENA-SLEDAI Flare Index) at the subsequent visit after drug tapering. We used generalised estimating equations and Cox proportional hazard models to compare tapering attempts that had begun in LLDAS, remission, and complete remission., Findings: Between May 1, 2013, and Dec 31, 2020, 4106 patients were recruited to the cohort, 3002 (73·1%) of whom were included in our analysis. 2769 (92·2%) participants were female, 233 (7·8%) were male, and 2636 (88·1%) of 2993 with ethnicity data available were Asian. The median age was 39·5 years (IQR 29·0-50·0). There were 14 808 patient visits for patients in LLDAS, or remission or complete remission, of which 13 140 (88·7%) entered the final multivariable model after excluding missing data. Among the 9863 visits at which patients continued the same therapy, 1121 (11·4%) flared at the next visit, of which 221 (19·7%) were severe flares. Of the 3277 visits at which a patient received a tapering of therapy, 557 (17·0%) flared at the next visit, of which 120 (21·5%) were severe flares. Tapering was associated with higher odds of flare compared with continuing the same therapy (odds ratio [OR] 1·24 [95% CI 1·10-1·39]; p=0·0005). Of 2095 continuous tapering attempts, 860 (41·1%) were initiated in LLDAS, 596 (28·4%) in remission, and 639 (30·5%) in complete remission. Tapering initiated in LLDAS (OR 1·37 [95% CI 1·03-1·81]; p=0·029) or remission (1·45 [1·08-1·94]; p=0·013) had higher odds of flare in 1 year compared with complete remission. Tapering in LLDAS (hazard ratio 1·24 [95% CI 1·04-1·48]; p=0·016) or remission (1·30 [1·08-1·56]; p=0·0054) had a significantly shorter time to first flare than tapering initiated in complete remission. Attaining sustained LLDAS, remission, or complete remission for at least 6 months just before the time of taper was associated with lower odds of flare at next visit, flares in 1 year, and longer time to flare., Interpretation: Tapering of corticosteroids or immunosuppressive therapy in patients with stable SLE was associated with excess flares. Our findings suggest that drug tapering should be carefully considered, weighing the risks and benefits, and is best exercised in complete (clinical and serological) remission and after maintaining stable disease for at least 6 months., Funding: AstraZeneca, BMS, Eli Lily, Janssen, Merck Serono, GSK, and UCB., Competing Interests: Declaration of interests YK received honoraria from GSK, AstraZeneca, Sanofi, Pfizer Japan, Janssen Pharmaceutical, Chugai Pharmaceutical, Asahi Kasei Pharma, Astellas Pharma, and Mitsubishi Tanabe Pharma Corporation.

Rheumatoid arthritis (RA) is an involving chronic systemic inflammatory disease which mainly affects the joints. Several factors including genetic, environment and infections have been acknowledged as being involved in the pathogenesis and aggravation of RA. Air pollution, particularly particulate matter is widely recognized as a cause of health problems. This review is to summarize and discuss the association between air pollutants and the development or the aggravation of RA based on evidence from in vitro, in vivo and clinical studies. The results from the review found that air pollutants can stimulate immunological processes and stimulate inflammatory mediators and autoantibodies productions, both in intro and in vivo studies. In addition, air pollutants can induce RA and aggravate RA disease activity. Unfortunately, there also are some discrepancies in the results, which might be due to the type cell line and the concentration of air pollutants used in the in vitro and in vivo studies, as well as the concentration and duration of exposure in human studies. These findings suggest that future studies focused on elucidating these mechanisms using advanced techniques and identifying reliable biomarkers to assess individual susceptibility and disease activity should be carried out. Longitudinal studies, intervention strategies, and policy implications also should be explored. A comprehensive understanding on these association will facilitate targeted approaches for prevention and management of air pollutant-induced RA and improve health outcome., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

Background: The infliximab biosimilar CT-P13 was approved in Thailand in 2015. Methods: This open-label, multicenter, post-marketing surveillance study evaluated the safety (events of special interest [ESIs]; primary end point) and effectiveness of 46 weeks of CT-P13 treatment according to routine practice in patients with rheumatoid arthritis (RA), ankylosing spondylitis (AS), or psoriatic arthritis (PsA), with 1 year follow-up post-treatment. Results: 30 patients were enrolled (16 RA, 8 AS and 6 PsA). Infections were the most frequently reported study drug-related ESIs (2 RA and 2 AS). One patient with RA and one with PsA experienced infusion-related reactions. No cases of tuberculosis, malignancy (as expected, given 1 year follow-up), or drug-induced liver disease were reported. Disease activity improved across indications. Conclusion: CT-P13 was well tolerated and effective across indications.

Cardiac wall rupture (CWR) is a serious and often fatal complication of myocardial infarction (MI). Despite an increase in the incidence of MI in patients with systemic lupus erythematosus (SLE), cases of CWR in these patients have been reported rarely. This study reports an SLE patient with CWR and pseudoaneurysm formation and reviews previously reported cases of CWR in SLE patients. An English language literature review of from the PubMed, EMBASE, and Scopus databases on published cases of CWR in SLE, up until January 2023, was performed and analyzed. The search identified 4 patients, including the present one, 5 cases altogether. All of them were female aged 27-40 years, and 3 of them had had SLE for 10 years or more. Chest pain and dyspnea were the common presentations. All had left ventricular (LV) wall rupture. Three patients had LV wall rupture with pseudoaneurysm formation (one had MI with normal coronary artery, one myocardial necrosis secondary from small coronary artery vasculitis and one MI from uncertain cause). The other 2 patients had LV free wall rupture (one had MI with extensive coronary atherosclerosis with coronary arteritis, and the other septic myocarditis with septic coronary arteritis) and these 2 patients died before the diagnosis was made. Three patients with pseudoaneurysm received surgical correction with good clinical outcomes in all. Cardiac wall rupture is a serious and often fatal cardiac complication. Emergency diagnosis and appropriate management with an experienced cardiology team is crucial. Surgical correction is the treatment of choice. Key Points • Cardiac wall rupture, a serious and often fatal cardiac complication, has rarely been described in SLE patients. • Emergency diagnosis and appropriate management with an experienced cardiology team is crucial. Surgical correction is the treatment of choice., (© 2023. The Author(s), under exclusive licence to International League of Associations for Rheumatology (ILAR).)

Background: Several studies have compared the clinical features and outcomes of late- and early-onset systemic lupus erythematosus (SLE) patients. However, these previous studies were uncontrolled. The current study aimed to compare late- and early-onset SLE patients while controlling for sex and year at diagnosis (± 1 year)., Methods: The medical records of SLE patients in a lupus cohort from January 1994 to June 2020 were reviewed. Late-onset patients were identified as those with an age at diagnosis ≥ 50 years. The early-onset patients (age at diagnosis < 50 years) were matched by sex and year at diagnosis with the late-onset patients at a ratio of 2:1. Clinical manifestations, disease activity (mSLEDAI-2K), organ damage scores, treatment, and mortality were compared between the two groups., Results: The study comprised 62 and 124 late- and early-onset patients, respectively, with a mean follow-up duration of 5 years. At disease onset, when comparing the early-onset patients with the late-onset patients, the latter group had a higher prevalence rate of serositis (37.0% vs. 14.5%, p < 0.001) and hemolytic anemia (50.0% vs. 33.9%, p = 0.034) but lower prevalence rate of malar rash (14.5% vs. 37.1%, p = 0.001), arthritis (41.9% vs. 62.1%, p = 0.009), leukopenia (32.3% vs. 50.0%, p = 0.022) and lymphopenia (50.0% vs. 66.1%, p = 0.034). The groups had similar SLE disease activity (7.41 vs. 7.50), but the late-onset group had higher organ damage scores (0.37 vs. 0.02, p < 0.001). The rates of treatment with corticosteroids, antimalarial drugs, or immunosuppressive drugs were not different. At their last visit, the late-onset patients still had the same pattern of clinically significant differences except for arthritis; additionally, the late-onset group had a lower rate of nephritis (53.2% vs. 74.2%, p = 0.008). They also had a lower level of disease activity (0.41 vs. 0.57, p = 0.006) and received fewer antimalarials (67.7% vs. 85.5%, p = 0.023) and immunosuppressive drugs (61.3% vs. 78.2%, p = 0.044), but they had higher organ damage scores (1.37 vs. 0.47, p < 0.001) and higher mortality rates/100-person year (3.2 vs. 1.1, p = 0.015). After adjusting for disease duration and baseline clinical variables, the late-onset patients only had lower rate of nephritis (p = 0.002), but still received fewer immunosuppressive drugs (p = 0.005) and had a higher mortality rate (p = 0.037)., Conclusions: In this sex- and year at diagnosis-matched controlled study, after adjusting for disease duration and baseline clinical variables, the late-onset SLE patients had less renal involvement and received less aggressive treatment, but had a higher mortality rate than the early-onset patients., (© 2023.

Objective: In trials of systemic lupus erythematosus (SLE), the SLE Responder Index (SRI) is the most commonly used primary efficacy end point but has limited validation against long-term outcomes. We aimed to investigate associations of attainment of a modified version of the SRI (mSRI) with key clinical outcomes in SLE patients with up to 5 years of follow-up., Methods: We used data from a large multicenter, longitudinal SLE cohort in which patients received standard of care. The first visit with active disease (defined as SLE Disease Activity Index 2000 [SLEDAI-2K] score ≥6) was designated as baseline, and mSRI attainment (defined as a reduction in SLEDAI-2K ≥4 points with no worsening in physician global assessment ≥0.3 points) was determined at annual intervals from baseline up to 5 years. Associations between mSRI attainment and outcomes including disease activity, glucocorticoid dose, flare, damage accrual, Lupus Low Disease Activity State (LLDAS), and remission were studied., Results: We included 2,060 patients, with a median baseline SLEDAI-2K score of 8. An mSRI response was attained by 56% of patients at 1 year, with similar responder rates seen at subsequent annual time points. Compared to nonresponders, mSRI responders had significantly lower disease activity and prednisolone dose and higher proportions of LLDAS and remission attainment at each year, and less damage accrual at years 2 and 3. Furthermore, mSRI responder status at 1 year predicted clinical benefit at subsequent years across most outcomes, including damage accrual (odds ratio [OR] range 0.58-0.69, P < 0.05 for damage accrual ORs at all time points)., Conclusion: In SLE patients with active disease receiving standard of care, mSRI attainment predicts favorable outcomes over long-term follow-up, supporting the clinical meaningfulness of SRI attainment as an SLE trial end point., (© 2022 The Authors.

Objectives: This study aimed to assess the cost-effectiveness of biologic disease-modifying antirheumatic drugs (bDMARDs) for treating patients with psoriatic arthritis who failed conventional synthetic disease-modifying antirheumatic drugs (csDMARDs)., Methods: A decision tree and Markov model were constructed to capture long-term costs and outcomes from a societal perspective. Patients with psoriatic arthritis who failed 2 previous csDMARDs were modeled over a 3-month cycle with a lifetime horizon. Clinical probabilities were derived from a published meta-analysis. Prices of bDMARDs were proposed by pharmaceutical companies. Other costs and utilities were based on data in Thailand. All costs and outcomes were discounted at a 3% annual rate. Incremental cost-effectiveness ratio and a series of sensitivity analyses were performed., Results: All 11 bDMARDs (3 infliximab originator and biosimilars, 2 etanercept originator and biosimilar, golimumab, 2 secukinumab 150 mg and 300 mg, 3 adalimumab biosimilars) gained better quality-adjusted life-years (QALYs) with more costly than csDMARDs. Infliximab had the highest QALYs compared with other bDMARDs. Only secukinumab 150 mg showed the incremental cost-effectiveness ratio below the Thai threshold of 5152 US dollars per QALY. Cost of bDMARDs was the most influential factor., Conclusions: At the current price, secukinumab 150 mg shows the value for money in the Thai context. Price negotiation is of great importance for other bDMARDs., (Copyright © 2022 International Society for Health Economics and Outcomes Research. Published by Elsevier Inc. All rights reserved.)

Introduction/objectives: Scleroderma is a rare complication in taxanes therapy. Although individual cases of taxanes-induced scleroderma have been reported, the clinical manifestation and treatment outcomes were reviewed and summarized rarely. This study reported a patient who developed diffuse scleroderma and possible scleroderma renal crisis after paclitaxel therapy for ureter cancer., Method: A PubMed literature review on published cases of taxanes-induced scleroderma up until April 2022 was included for analysis., Results: The search identified 27 patients with adequate information for analysis. Of the 28 patients, including the one presented here, 22 were female. Peripheral edema was the most common symptom in all but one patient, and often accompanied by erythema in 11. Symptoms usually occurred in half of the patients within the 4 th course of treatment. Skin lesions gradually progressed to skin fibrosis, and extended proximally. Internal organ involvements were uncommon. Antinuclear antibody tests were positive occasionally, but anti-Scl70 and anti-centromere usually were negative. Taxanes therapy was discontinued, continued and unavailable in 21, 3, and 4 patients, respectively. Corticosteroids for skin lesions with or without immunosuppressive drugs were given to 15 patients. Of 25 patients with available skin outcomes, 19 improved. There was no significant skin improvement between those who did or did not receive skin treatment (62.5% vs. 75.0%, p = 0.37). Skin usually improved after discontinuing taxanes., Conclusion: Taxanes-induced scleroderma is different from idiopathic scleroderma. Physicians should be aware of this condition in order to provide early diagnosis and apply appropriate management in order to avoid serious complications from severe skin sclerosis. Key Points • Scleroderma is a rare but unique and serious complication of taxanes therapy • Skin manifestations and distribution are similar to idiopathic scleroderma, but vascular phenomenon, internal organ involvement and scleroderma-associated auto-antibodies are presented rarely. Skin improvement usually occurs shortly after discontinuing taxanes • The role of immunosuppressive therapy in treating taxanes-induced scleroderma is not clear., (© 2022.

HLA studies in patients with systemic sclerosis (SSc) have shown variable results. This study aimed to examine the association of HLA class I and II risk alleles in Thai SSc patients, and clarify the contribution of risk HLA alleles to the pathogenesis and clinical manifestations. Blood samples from 92 SSc patients and 135 healthy controls (HCs) were collected. Eleven loci of the HLA class I (HLA-A, B, and C) and class II (HLA-DR, DP, and DQ) genes were determined by a 3-field (6-digit) analysis using the Next Generation DNA Sequencing (NGS) method. Anti-topoisomerase-I antibodies (ATA) and anti-centromere antibodies (ACA) were identified by ELISA methods. Allele frequencies (AFs) of HLA-DRB1*15:02:01, DRB5*01:02:01, DQB1*05:01:24, DPB1*13:01:01, and DQA1*01:01:01 were increased significantly in the whole SSc and SSc patients with positive ATA, but with negative ACA (SSc/ATA+/ACA-). Of these, DPB1*13:01:01 was the most susceptible allele. The DRB1*15:02:01, DQB1:05:01:24, and DPB1*13:01:01 alleles were estimated to locate on the unique haplotype, and haplotype frequency was estimated to be significantly higher than those in the HCs (p = 0.002). The linkage analysis of DRB1*15/16 revealed that most of the DRB1*15:02:01 alleles were linked to DRB5*01:02:01 or DRB5*01:08:01N. The linkage of DRB1*16:02:01 to DRB5*01:01:01 was observed frequently. The associations of risk alleles with several SSc clinical features were observed. HLA-DRB1*15:02:01, DRB5*01:02:01, DQB1*05:01:24, and DPB1*13:01:01 on the unique haplotype were associated with the pathogenesis and clinical features of SSc in Thai patients. The linkage of DRB1*15:02:01 to DRB5*01:08:01N was observed commonly in northern Thai patients., (© 2022 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Background: The selection and categorisation of laboratory tests in disease activity measures used within systemic lupus erythematosus (SLE) trial endpoints lack strong evidence. We aimed to determine whether longitudinal improvements in routinely measured laboratory tests are associated with measures of clinical improvement in patients with baseline active SLE., Methods: We included patients from a multicentre longitudinal cohort (recruited between May 1, 2013, and Dec 31, 2019) with active SLE (SLEDAI-2K ≥6) coinciding with an abnormality in at least one of 13 routine laboratory tests, at a visit designated as baseline. At 12 months, we analysed associations between thresholds of improvement in individual laboratory test results, measured as continuous variables, and five clinical outcomes using logistic regression. Primary outcomes were damage accrual and lupus low disease activity state (LLDAS), and secondary outcomes were modified SLE responder index (mSRI), physician global assessment (PGA) improvement of at least 0·3, and flare., Findings: We included 1525 patients (1415 [93%] women and 110 [7%] men, 1328 [87%] Asian ethnicity) in separate subsets for each laboratory test. The strongest associations with LLDAS and damage protection were seen with improvements in proteinuria (complete response: adjusted odds ratio [OR] 62·48, 95% CI 18·79-208·31 for LLDAS, OR 0·22, 95% CI 0·10-0·49 for damage accrual), albumin (complete response: adjusted OR 6·46, 95% CI 2·20-18·98 for LLDAS, OR 0·42, 95% CI 0·20-1·22 for damage accrual), haemoglobin (complete response: adjusted OR 1·97, 95% CI 1·09-3·53 for LLDAS, OR 0·33, 95% CI 0·15-0·71 for damage accrual), erythrocyte sedimentation rate (complete response: adjusted OR 1·71, 95% CI 1·10-2·67 for LLDAS, OR 0·53, 95% CI 0·30-0·94 for damage accrual), and platelets (complete response: adjusted OR 4·82, 95% CI 1·54-15·07 for LLDAS, OR 0·49, 95% CI 0·20-1·19 for damage accrual). Improvement in serological tests were mainly associated with PGA and mSRI. White cell and lymphocyte count improvements were least predictive., Interpretation: Improvements in several routine laboratory tests correspond with clinical outcomes in SLE over 12 months. Tests with the strongest associations were discrepant with laboratory tests included in current trial endpoints, and associations were observed across a range of improvement thresholds including incomplete resolution. These findings suggest the need to revise the use of laboratory test results in SLE trial endpoints., Funding: Abbvie., Competing Interests: Declaration of interests KC reports grants from the National Health and Medical Research Council and Royal Australian College of Physicians, personal fees from AstraZeneca, and sponsorship from Janssen and Pfizer.

Background: Treat-to-target goals for patients with systemic lupus erythematosus (SLE) have been validated to protect against organ damage and to improve quality of life. We aimed to investigate the association between lupus low disease activity state (LLDAS) and remission and risk of mortality in patients with SLE. We hypothesised that LLDAS has a protective association with mortality risk., Methods: In this prospective, multinational, longitudinal cohort study, we used data from patients with SLE in the Asia Pacific Lupus Collaboration cohort collected between May 1, 2013, and Dec 31, 2020. Eligible patients were adults (aged ≥18 years) who met either the 1997 American College of Rheumatology modified classification criteria for SLE or the 2012 Systemic Lupus International Collaborating Clinics classification criteria. The primary outcome was all-cause mortality, and LLDAS, remission, and variations of remission with lower glucocorticoid thresholds were the primary exposure variables. Survival analyses were used to examine longitudinal associations between these endpoints and risk of mortality. This study is registered with ClinicalTrials.gov, NCT03138941., Findings: Among a total of 4106 patients in the cohort, 3811 (92·8%) patients were included in the final analysis (median follow-up 2·8 years [IQR 1·0-5·3]; 3509 [92·1%] women and 302 [7·9%] men), of whom 80 died during the observation period (crude mortality rate 6·4 deaths per 1000 person-years). LLDAS was attained at least once in 43 (53·8%) of 80 participants who died and in 3035 (81·3%) of 3731 participants who were alive at the end of the study (p<0·0001); 22 (27·5%) participants who died versus 1966 (52·7%) who were alive at the end of the study attained LLDAS for at least 50% of observed time (p<0·0001). Remission was attained by 32 (40·0%) of 80 who died and in 2403 (64·4%) of 3731 participants who were alive at the end of the study (p<0·0001); 14 (17·5%) participants who died versus 1389 (37·2%) who were alive at the end of the study attained remission for at least 50% of observed time (p<0·0001). LLDAS for at least 50% of observed time (adjusted hazard ratio 0·51 [95% CI 0·31-0·85]; p=0·010) and remission for at least 50% of observed time (0·52 [0·29-0·93]; p=0·027) were associated with reduced risk of mortality. Modifying the remission glucocorticoid threshold (<5·0 mg/day prednisolone) was more protective against mortality than current remission definitions (0·31 [0·12-0·77]; p=0·012), and glucocorticoid-free remission was the most protective (0·13 [0·02-0·96]; p=0·046)., Interpretation: LLDAS significantly reduced the risk of mortality in patients with SLE. Remission did not further reduce the risk of mortality compared with LLDAS, unless lower glucocorticoid thresholds were used., Funding: The Asia-Pacific Lupus Collaboration received funding from Janssen, Bristol Myers Squibb, Eli Lilly, and UCB for this study., Competing Interests: Declaration of interests SVN has received consulting fees from Biogen and Boehringer Ingelheim; lecture or speaker fees from Janssen, Novartis, Pfizer, and GlaxoSmithKline; conference registration fees from Pfizer; and payment from Biogen for participation on an advisory board.

Objective: Evidence for the utility of medications in settings lacking randomized trial data can come from studies of treatment persistence. The present study was undertaken to examine patterns of medication use in systemic lupus erythematosus (SLE) using data from a large multicenter longitudinal cohort., Methods: Prospectively collected data from the Asia Pacific Lupus Collaboration cohort including disease activity (SLE Disease Activity Index 2000 [SLEDAI-2K]) and medication details, captured at every visit from 2013-2018, were used. Medications were categorized as glucocorticoids (GCs), antimalarials (AM), and immunosuppressants (IS). Cox regression analyses were performed to determine the time-to-discontinuation of medications, stratified by SLE disease activity., Results: Data from 19,804 visits of 2,860 patients were analyzed. Eight medication categories were observed: no treatment; GC, AM, or IS only; GC plus AM; GC plus IS; AM plus IS; and GC plus AM plus IS (triple therapy). Triple therapy was the most frequent pattern (31.4% of visits); single agents were used in 21% of visits, and biologics in only 3%. Time-to-discontinuation analysis indicated that medication persistence varied widely, with the highest treatment persistence for AM and lowest for IS. Patients with a time-adjusted mean SLEDAI-2K score of ≥10 had lower discontinuation of GCs and higher discontinuation of IS., Conclusion: Most patients received combination treatment. GC persistence was high, while IS persistence was low. Patients with high disease activity received more medication combinations but had reduced IS persistence, consistent with limited utility. These data confirm unmet need for improved SLE treatments., (© 2021 American College of Rheumatology.)

Purpose of the study: Parkinsonism in patients with systemic lupus erythematosus (SLE) is rare. This study reported a case of parkinsonism in SLE and reviewed the clinical features and outcomes of parkinsonism in SLE patients. Methods: English language literature of parkinsonism in SLE patients was reviewed. Results: There were 28 patients (19 adults and 9 children) with SLE and parkinsonism. Twenty-three patients were female. Of 26 patients whose disease duration was available parkinsonism occurred at SLE diagnosis and after SLE diagnosis in 6 and 20 patients, respectively. Twenty-five patients had active SLE. Hematologic, mucocutaneous and musculoskeletal systems were the 3 most common organs involved in SLE during parkinsonism onset. Rigidity, bradykinesia and resting tremor were the 3 most common parkinsonian symptoms. Compared with adults, child cases had significantly more psychosis (4 in 9 vs. 1 in 19, p  = .026), seizures or psychosis (6 in 9 vs. 2 in 19, p  = .005) and mutism (6 in 9 vs. none, p  < .001). Brain magnetic resonance imaging (MRI) was abnormal in 13 of 24 patients. Eight of nine patients had abnormal single-photon emission computed tomography (SPECT) and 5 and 3 showed hypoperfusion and hyperperfusion, respectively. The outcomes were resolution, partial response and persistent symptoms in 17, 7 and 4 patients, respectively. The outcome was no different whether or not dopamine therapy was included to corticosteroids and/or immunosuppressive drugs. Conclusions: Parkinsonism in SLE usually occurs during active SLE disease. Good response to corticosteroid and/or immunosuppressive drugs supports the immunologic mechanism in the pathogenesis.

Reports of inflammatory rheumatic diseases (IRD) in thalassemia are limited. This study aimed to determine the prevalence and clinical characteristics of IRD in patients with thalassemia disease. Consecutive adult patients with thalassemia disease, confirmed by hemoglobin typing, attending the Hematology Clinic between June 2019 and May 2021 were invited to join this study. All of them had their history taken and a physical examination for IRD. Those with IRD had their medical records reviewed. Sixty-three patients (transfusion-dependent in 50) were included in this study. There was α-, β-, and co-inheritance of α- and β-thalassemia in 22.22%, 73.02%, and 4.76% of the patients, respectively, with β-thalassemia/Hb E disease in 53.97%. Twenty-three patients had IRD (rheumatoid arthritis in 9, gout in 6, systemic lupus erythematosus in 3, spondyloarthropathy in 2, and one patient each with dermatomyositis, overlap syndrome, and unclassified polyarthralgia). Clinical manifestations and laboratory findings were similar to IRD patients in general. In 40 patients without IRD, direct and indirect Coombs tests and antinuclear antibody (ANA) were positive in 51.72%, 27.59%, and 10.26%, respectively. When comparing among these 40 patients, between those with non-transfusion-dependent thalassemia (n = 10) and those with transfusion-dependent thalassemia (n = 30), the latter had non-significantly more positive direct Coombs (60.87% vs. 16.67%), indirect Coombs (30.43% vs. 16.67%), and ANA tests (13.33% vs. 0%). The prevalence of IRD in patients with thalassemia disease was rather high. Positive direct Coombs test and ANA were common in transfusion-dependent patients., (© 2022.

Objectives: To translate the Gout Assessment Questionnaire version 2.0 (GAQ2.0) with Gout Impact (GI) Scale (GIS) into Thai and determine its psychometric property in gout patients with acute arthritis (acute arthritis group) and during the intercritical period (chronic gout group)., Methods: Translation followed the ISPOR recommendations. Cronbach's α, intraclass correlation coefficient (ICC) and standardized response mean (SRM) were used to determine internal consistency, reliability and responsiveness to change, respectively. Correlations between GI subscales with generic health-related quality of life (HRQoL) questionnaires (SF-36, HAQ-DI and EQ-5D-5L) and gout clinical parameters were determined., Results: The acute arthritis group and the chronic gout group comprised 27 and 92 patients, respectively. Internal consistency was sufficient for all GI subscales (Cronbach's α = 0.80-0.98), reliability was moderate to good in most GI subscales (ICC = 0.54-0.88) and responsiveness to change was moderate to large in most GI subscales (SRM = 0.43-0.98). The GI subscales correlated better with SF-36 than HAQ-DI and EQ-5D-5L. In the acute arthritis group, the unmet gout treatment needs subscale showed large and moderate negative correlation with tophi and serum uric acid, respectively. In the chronic gout group, the gout concern overall subscale had statistically significant, moderate correlation with overall gout severity rated by the patients and number of gout attacks over the past year, while the well-being during attack subscale and total GIS score had statistically significant, moderate correlation with overall gout severity rated by the patients., Conclusion: The Thai GAQ2.0 GIS showed acceptable internal consistency, reliability and responsiveness to change and correlated significantly with generic HRQoL questionnaires and clinical parameters. Key Points • The Thai GAQ2.0 GIS showed acceptable internal consistency, reliability and responsiveness to change in gout patients both during acute attack and during the intercritical period • The GI subscales showed significant correlation with SF-36 and HAQ questionnaires and gout clinical parameters in gout patients both during acute attack and during the intercritical period • The Thai GAQ2.0 GIS subscales should be used in conjunction with generic HRQoL for complete HRQoL assessment in gout patients., (© 2022.

Background: The unmet need in systemic lupus erythematosus (SLE) with the current standard of care is widely recognised, but few studies have quantified this. The recent definition of treat-to-target endpoints and other thresholds of uncontrolled disease activity provide an opportunity to formally define unmet need in SLE. In this study, we enumerated the prevalence of these states and examined their association with adverse outcomes., Methods: Data were collected prospectively in a 13-country longitudinal SLE cohort between 2013 and 2019. Unmet need was defined as never attaining lupus low disease activity state (LLDAS), a time-adjusted mean SLEDAI-2K (AMS) > 4, or ever experiencing high disease activity status (HDAS; SLEDAI-2K ≥10). Health-related quality of life (HRQoL) was assessed using SF36 (v2) and damage accrual using the SLICC-ACR SLE Damage Index (SDI)., Results: A total of 3384 SLE patients were followed over 30,313 visits (median [IQR] follow-up 2.4 [0.4, 4.3] years). Eight hundred thirteen patients (24%) never achieved LLDAS. Median AMS was 3.0 [1.4, 4.9]; 34% of patients had AMS > 4. Twenty-five per cent of patients had episodes of HDAS. Each of LLDAS-never, AMS>4, and HDAS-ever was strongly associated with damage accrual, higher glucocorticoid use, and worse HRQoL. Mortality was significantly increased in LLDAS-never (adjusted HR [95% CI] = 4.98 [2.07, 12.0], p<0.001) and HDAS-ever (adjusted hazard ratio (HR) [95% CI] = 5.45 [2.75, 10.8], p<0.001) patients., Conclusion: Failure to achieve LLDAS, high average disease activity, and episodes of HDAS were prevalent in SLE and were significantly associated with poor outcomes including organ damage, glucocorticoid exposure, poor quality of life, and mortality., (© 2022.

Objectives: This study is aimed at determining the role of T cells by assessing the numbers of IFN- γ - and IL-2-secreting T cells following stimulation with peptides derived from DNA topoisomerase-I protein in Thai SSc patients., Methods: Fifty Thai SSc patients and 50 healthy controls (HC) joined this study. IFN- γ and IL-2 levels upon stimulation of T cells with 6 peptides derived from DNA topoisomerase-I protein were determined. Anti-nuclear antibodies (ANA) and anti-Scl-70 antibodies were determined by using the ELISA method., Results: In SSc patients, we detected a significantly higher number of IFN- γ - and IL-2-secreting CD8 + T cells than IFN- γ - and IL-2-secreting CD4 + T cells after stimulation with pooled peptides derived from DNA topoisomerase-I protein. A similar percentage of CD4 + IL-2 + , CD4 + IFN- γ + , and CD8 + IL-2 + were detected following stimulation with DNA topoisomerase-I protein -in SSc patients with anti-Scl-70 antibody (SSc/anti-Scl-70 + ) and those without. In contrast, the amount of CD8 + IFN- γ + cells was significantly higher in SSc/anti-Scl-70 + than those without. Stimulation with individual peptides showed that CSLRVEHINLHPELD (sPep3; 15 amino acids; position 505-519 of DNA topoisomerase-I protein) was the optimal epitope that induced T cells secreting the highest levels of IFN- γ and IL-2. A higher percentage of IFN- γ + CD4 + T cells was detected in SSc/anti-Scl-70 + than those without the following stimulation with peptides 2 (amino acid position 475-486 [RAVALYFIDKLA] of protein DNA topoisomerase)., Conclusion: The results from this study emphasize the critical role of DNA topoisomerase-I peptides on the activation of T cells in SSc patients. The findings provide a better understanding of SSc's immunopathogenesis and may lead to the development of diagnostic tools and specific treatments for SSc in the future., Competing Interests: All authors declare no conflict of interest., (Copyright © 2022 Oranit Likhit et al.)

Background/objective: The aim of this study was to compare disease activity and rate and severity of flares between pregnant and nonpregnant systemic lupus erythematosus (SLE) patients., Methods: Medical records of pregnant SLE patients seen between January 1993 and June 2017 were reviewed. Nonpregnant SLE controls were matched by age at diagnosis and disease duration before pregnancy. Systemic lupus erythematosus disease activity and flares were determined by the cSLEDAI (clinical Systemic Lupus Erythematosus Disease Activity Index) and Safety of Estrogens in Lupus Erythematosus National Assessment-SLEDAI Flare Index, respectively. Disease activity was measured from 6 months before conception (-6 months) until the postpartum period. The repeated measures mixed model, Cox regression, and cumulative hazard plots were used for statistical analysis., Results: Ninety pregnancies occurred in 77 patients. The cSLEDAI scores from -6 months to the postpartum period were comparable between the pregnancy and control group, but slightly yet significantly higher in the controls at conception (mean ± SEM, 3.57 ± 0.45 vs 1.90 ± 0.36; p = 0.019). When compared with the controls, during the pregnancy and postpartum period, the pregnancy group did not have significantly higher incidence of flare (41.11% vs 28.89%, p = 0.086 and 7.78% vs 11.11%, p = 0.445, respectively) or flare category (severe flare) (75.68% vs 53.85%, p = 0.070 and 85.71% vs 70.00%, p = 0.603, respectively). The flare incidence rate (95% confidence interval)/100 patient-months in the pregnancy and control group was 6.75 (4.89-9.32) and 4.34 (2.96-6.38), respectively, giving the adjusted hazards for flare (95% confidence interval) of 1.54 (0.91-2.61) (p = 0.110)., Conclusions: There was no overall significant increase in SLE disease activity, flare incidence, and flare severity in pregnant SLE patients when compared with their properly matched nonpregnant SLE controls., Competing Interests: The authors declare no conflict of interest., (Copyright © 2021 Wolters Kluwer Health, Inc.

Background: Gout is the most prevalent inflammatory arthritis in the Asia-Pacific region and worldwide. This clinical practice guideline (CPG) aims to provide recommendations based on systematically obtained evidence and values and preferences tailored to the unique needs of patients with gout and hyperuricemia in Asia, Australasia, and the Middle East. The target users of these guidelines are general practitioners and specialists, including rheumatologists, in these regions., Methods: Relevant clinical questions were formulated by the Steering Committee. Systematic reviews of evidence were done, and certainty of evidence was assessed using Grading of Recommendations Assessment, Development and Evaluation methodology. A multi-sectoral consensus panel formulated the final recommendations., Results: The Asia-Pacific League of Associations for Rheumatology Task Force developed this CPG for treatment of gout with 3 overarching principles and 22 recommendation statements that covered the treatment of asymptomatic hyperuricemia (2 statements), treatment of acute gout (4 statements), prophylaxis against gout flare when initiating urate-lowering therapy (3 statements), urate-lowering therapy (3 statements), treatment of chronic tophaceous gout (2 statements), treatment of complicated gout and non-responders (2 statements), treatment of gout with moderate to severe renal impairment (1 statement), and non-pharmacologic interventions (5 statements)., Conclusion: Recommendations for clinically relevant scenarios in the management of gout were formulated to guide physicians in administering individualized care., (© 2021 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.)

Objectives: This study aims to compare pregnancy outcomes between systemic lupus erythematosus (SLE) patients who attained clinical remission based on the Definition of Remission in SLE (DORIS) and those with lupus low disease activity based on Low Lupus Disease Activity State (LLDAS)., Patients and Methods: Between January 1993 and June 2017, a total of 90 pregnancies (one twin pregnancy) from 77 patients (mean age: 26.9±4.8 years; range, 17.9 to 37.3 years) were included in the study. The clinical remission and the LLDAS groups were modified into modified clinical remission and LLDAS groups, respectively by omitting Physician Global Assessment (PGA). The clinical SLE disease activity index (cSLEDAI) score was used for LLDAS., Results: Pregnancies in 49 patients occurred, when they were in modified clinical remission and in 57 in modified LLDAS. There was no significant difference in demographic characteristics, disease activity, or medication received at conception between the two groups. Pregnancy outcomes were similar between the modified clinical remission and the modified LLDAS groups in terms of successful pregnancy (83.67% vs. 84.21%), full-term births (38.78% vs. 38.60%), fetal losses (16.33% vs. 15.79%), spontaneous abortions (14.29% vs. 14.04%), small for gestational age infants (18.37% vs. 19.30%), low birth weight infants (42.86% vs. 40.35%), maternal complications (46.94% vs. 49.12%), and maternal flares (36.73% vs. 40.35%). The agreement of pregnancy outcomes was very high between the two groups (91.11% agreement)., Conclusion: Pregnancy outcomes in SLE patients who achieved modified clinical remission and modified LLDAS were comparable., Competing Interests: Conflict of Interest: The authors declared no conflicts of interest with respect to the authorship and/or publication of this article., (Copyright © 2022, Turkish League Against Rheumatism.)

Background: The adjusted-Global Antiphospholipid Syndrome Score (aGAPSS) has been validated and used to predict antiphospholipid antibodies (aPL) related to vascular thrombosis (VT)., Objective: To validate aGAPSS for predicted aPL-related VT and pregnancy complications (PC) in Thai systemic lupus erythematosus (SLE) patients., Methods: A cross-sectional study was performed among Thai SLE patients with clinical manifestations; history of VT and PC, cardiovascular risk factors, and aPL profiles were collected. The aGAPSS was calculated from the sum of the risk factors (hyperlipidemia = 3.0, arterial hypertension = 1.0, anti-cardiolipin antibody = 5.0, anti-b2 glycoprotein I antibody = 4.0, and lupus anticoagulant = 4.0)., Results: Of 132 SLE patients, 12 (9.1%) had VT and 5 (4.1%) had PC. When comparing the aGAPSS (median; interquartile range [IQR]) of patients with events (VT and/or PC) (6.5; IQR 3.3-9.0), VT (8.0; IQR 4.0-9.0), arterial thrombosis (3.5; IQR 1.0-5.8), and PC (9.0; IQR 8.0-11.5), and the aGAPSS of patients without an event (3.0; IQR 0-4.0), aGAPSS of patients with events was significantly higher, except in patients with arterial thrombosis. An aGAPSS of 4.5 or more was associated with risk of aPL-related VT (sensitivity 71.4%, specificity 76.7%), and an aGAPSS of 6.0 or more was associated with risk of aPL-PC (sensitivity 100%, specificity 84.0%)., Conclusion: The aGAPSS could predict the risk of aPL-PC and aPL-related VT in Thai SLE patients., (© 2021 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.)

Objective: The prevalence and associations of leucopenia in SLE remain incompletely understood. We evaluated associations of disease activity and medication use with leucopenia (lymphopenia and neutropenia) in a multinational, prospectively followed SLE cohort., Methods: Data from the Asia Pacific Lupus Collaboration cohort, in which disease activity and medications were prospectively captured from 2013 to 2018, were used. Predictors of lymphopenia (lymphocyte count <0.8 × 109/l) and neutropenia (neutrophil count <1.5 × 109/l) were examined using multiple failure, time-dependent survival analyses., Results: Data from 2330 patients and 18 287 visits were analysed. One thousand and eighteen patients (43.7%) had at least one episode of leucopenia; 867 patients (37.2%) had lymphopenia, observed in 3065 (16.8%) visits, and 292 (12.5%) patients had neutropenia, in 622 (3.4%) visits. After multivariable analyses, lymphopenia was associated with overall disease activity, ESR, serology, prednisolone, AZA, MTX, tacrolimus, CYC and rituximab use. MTX and ciclosporin were negatively associated with neutropenia. Lupus low disease activity state was negatively associated with both lymphopenia and neutropenia., Conclusion: Both lymphopenia and neutropenia were common in SLE patients but were differentially associated with disease and treatment variables. Lymphopenia and neutropenia should be considered independently in studies in SLE., (© The Author(s) 2021. Published by Oxford University Press on behalf of the British Society for Rheumatology.)

Aims: Studies on polymorphisms of the cytotoxic T lymphocytes associated antigen-4 (CTLA-4) genes in rheumatic disease patients are limited in Southeast Asia. This pilot study aimed to determine CTLA-4 polymorphisms in Thai patients with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and systemic sclerosis (SSc), and correlate them with serology., Method: One-hundred RA, 70 SLE and 50 SSc patients, and 99 healthy controls (HCs) were included in this study. Polymorphisms of the CTLA-4 gene at +49A/G, -318C/T, -1661A/G and -1722T/C loci were determined by polymerase chain reaction restriction fragment length polymorphism methods. Patient serum samples were determined as follows: RA (rheumatoid factor [RF] and anticyclic citrullinated peptide [anti-CCP]), SLE (antinuclear antibodies [ANA], anti-double-stranded DNA [anti-dsDNA], anti-Smith [anti-Sm], anti-ribonucleoprotein [anti-RNP], and anti-Sjögren's syndrome antigen A [SSA]), and SSc (ANA, anti-RNP, anti-SSA, anti-topoisomerase-1 [anti-Scl70], and anti-centromere antibodies [ACA])., Results: Among the 4 loci studied (+49A/G, -318C/T, -1661A/G and -1722T/C) only the A allele frequency at the +49A/G was significantly higher in the RA patients than their HCs (47.25% vs 35.86%, P = .029, odds ratio [OR] 1.60; 95% CI 1.04-2.47). It also was significantly higher in the subgroup of RA patients with positive RF and anti-CCP than their HCs (47.50% vs 35.86%, P = .020, OR 1.62; 95% CI 1.06-2.47 and 48.89% vs 35.86%, P = .012, OR 1.71; 95% CI 1.11-2.64, respectively). No polymorphisms at these 4 loci were observed in SLE or SSc patients., Conclusion: The A allele at +49A/G locus of the CTLA-4 gene was associated with RA in Thais., (© 2021 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.)

Objective: To determine longitudinal associations between Physician Global Assessment (PGA) and patient-reported outcomes (PROs) in patients with systemic lupus erythematosus (SLE)., Methods: Patients attending a rheumatology clinic between 2013 and 2017 completed specific (SLEQOL) and generic (SF36) health-related quality of life (HRQoL) surveys and rated their global rating of change (GRC) at each visit. PGA, SLEDAI-2K and SLE Flare Index (SFI) were also captured on all visits. Generalised estimating equations (GEE) methods were used to examine longitudinal associations of PGA with PROs and clinical indicators., Results: 337 patients were followed for a median [IQR] of 3.2 [1.6, 3.4] years (2,059 visits). High PGA (>1) was strongly associated with high SLEDAI-2K scores, the presence of flares and poor PROs. Odd ratios (OR) [95% CI] of PGA > 1 in patients with SLEDAI-2K >4 & <10 and SLEDAI-2K ≥10, compared to SLEDAI-2K ≤ 4, were 3.46 [2.36, 5.08], p < 0.001 and 6.39 [4.30, 9.49], p < 0.001, respectively. OR [95% CI] of PGA > 1 in patients with mild-to-moderate or severe flares were 2.09 [1.62, 2.71], p < 0.001 and 4.42 [3.21, 6.07], p < 0.001, respectively. Mental components of both SLEQOL (mood, self-image) and SF36 (MCS) surveys demonstrated significant associations with high PGA. After adjusting for SLEDAI-2K, one-point increase in PGA was associated with reductions in SLEQOL total score and SF36-MCS by 2.33 (regression coefficient (RC) [95% CI] = -2.33 [-3.77, -0.88], p = 0.002), and 4.16 (RC [95% CI] = -4.16 [-5.19, -3.13], p < 0.001) points, respectively. Associations of some physical components (SLEQOL-symptoms, and SF36-PCS) with PGA attenuated when adjusted for SLEDAI-2K. Patients who rated low scores of GRC, which indicate health deterioration, were twice as likely to have PGA > 1 (OR [95%CI] 1.99 [1.25, 3.16], p = 0.004)., Conclusion: High PGA was strongly associated with poor mental health, high disease activity and flares. This study confirms the value of PGA as an efficient assessment tool for SLE.

Objectives: The effect of coffee on serum uric acid (SUA) has shown conflicting results. This study was to determine the effects of caffeinated coffee (CC) and decaffeinated coffee (DC) on SUA, serum xanthine oxidase activity (sXOA) and urine uric acid clearance (UAC)., Methods: This was a prospective randomised within-subject experimental study design of 51 healthy male participants. Each study period consisted of 3 periods, including a control, an intervention, and washout period for 1, 3 and 1 week, respectively. During the intervention period, the participants received 2, 4 or 6 gram/day of coffee, either CC or DC., Results: For DC groups, SUA significantly decreased by 6.5 (±1.1) mg/dL to 6.2 (±1.1) mg/dL during the intervention period (p=0.014). sXOA significantly increased by 0.05 (±0.07) nmol/min/mL to 0.20 (±0.38) nmol/min/mL during the intervention period (p=0.010) of CC. For UAC, there was no significant change with CC or DC. In hyperuricaemic participants, SUA significantly decreased by 7.7 (±0.7) mg/dL to 7.2 (±0.7) mg/dL during the intervention period (p=0.028) of DC. For non-hyperuricaemic, CC significantly increased SUA by 5.9 (±0.7) mg/dL to 6.2 (±0.9) mg/dL during the intervention period (p=0.008) and significantly decreased SUA to 6.0 (±0.8) mg/dL (p=0.049) during the withdrawal period. A significant increase of sXOA according with SUA in CC groups from 0.05 (±0.07) nmol/min/mL to 0.25 (±0.44) nmol/min/mL during the intervention period (p=0.040) was presented in non-hyperuricaemic participants., Conclusions: DC had a significant decrease of SUA during the intervention period. However, in non-HUS participants, SUA significantly increased in CC.

Aim: To update previous guidance of the Asia Pacific League of Associations for Rheumatology (APLAR) on the management of patients with rheumatic and musculoskeletal diseases (RMD) during the coronavirus disease 2019 (COVID-19) pandemic., Methods: Research questions were formulated focusing on diagnosis and treatment of adult patients with RMD within the context of the pandemic, including the management of RMD in patients who developed COVID-19. MEDLINE was searched for eligible studies to address the questions, and the APLAR COVID-19 task force convened 2 meetings through video conferencing to discuss its findings and integrate best available evidence with expert opinion. Consensus statements were finalized using the modified Delphi process., Results: Agreement was obtained around key aspects of screening for or diagnosis of COVID-19; management of patients with RMD without confirmed COVID-19; and management of patients with RMD with confirmed COVID-19. The task force achieved consensus on 25 statements covering the potential risk of acquiring COVID-19 in RMD patients, advice on RMD medication adjustment and continuation, the roles of telemedicine and vaccination, and the impact of the pandemic on quality of life and on treatment adherence., Conclusions: Available evidence primarily from descriptive research supported new recommendations for aspects of RMD care not covered in the previous document, particularly with regard to risk factors for complicated COVID-19 in RMD patients, modifications to RMD treatment regimens in the context of the pandemic, and COVID-19 vaccination in patients with RMD., (© 2021 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.)

Abstract: Studies on predicting factors for adverse pregnancy outcomes (APOs) in Thai patients with systemic lupus erythematosus (SLE) are limited. This retrospective observation study determined APOs and their predictors in Thai patients with SLE.Medical records of pregnant SLE patients in a lupus cohort, seen from January 1993 to June 2017, were reviewed.Ninety pregnancies (1 twin pregnancy) from 77 patients were identified. The mean age at conception was 26.94 ± 4.80 years. At conception, 33 patients (36.67%) had active disease, 23 (25.56%) hypertension, 20 (22.22%) renal involvement, and 6 of 43 (13.95%) positive anti-cardiolipin antibodies or lupus anti-coagulants, and 37 (41.11%) received hydroxychloroquine. Nineteen patients (21.11%) had pregnancy loss. Of 71 successful pregnancies, 28 (31.11%) infants were full-term, 42 (46.67%) pre-term and 1 (11.11%) post-term; 19 (26.39%) were small for gestational age (SGA), and 38 (52.58%) had low birth weight (LBW). Maternal complications occurred in 21 (23.33%) pregnancies [10 (11.11%) premature rupture of membrane (PROM), 8 (8.89%) pregnancy induced hypertension (PIH), 4 (4.44%) oligohydramnios, 2 (2.22%) post-partum hemorrhage, and 1 (1.11%) eclampsia]. Patients aged ≥ 25 years at pregnancy and those ever having renal involvement had predicted pregnancy loss with adjusted odds ratio (AOR) [95% CI] of 4.15 [1.10-15.72], P = .036 and 9.21 [1.03-82.51], P = .047, respectively. Renal involvement predicted prematurity (6.02 [1.77-20.52, P = .004), SGA (4.46 [1.44-13.78], P = .009), and LBW in infants (10.01 [3.07-32.62], P < .001). Prednisolone (>10 mg/day) and immunosuppressive drugs used at conception protected against prematurity (0.11 [0.02-0.85], P = .034). Flares and hematologic involvement predicted PROM (8.45 [1.58-45.30], P = .013) and PIH (9.24 [1.70-50.24], P = .010), respectively. Cutaneous vasculitis (33.87 [1.05-1,094.65], P = .047), and renal (31.89 [6.66-152.69], P < .001), mucocutaneous (9.17 [1.83-45.90], P = .007) and hematologic involvement (128.00 [4.60-3,564.46], P = .004) during pregnancy predicted flare; while prednisolone (>10 mg/day) and immunosuppressive drug use at conception reduced that risk (0.08 [0.01-0.68, P = .021).APOs remain a problem in Thai pregnant SLE patients. Renal involvement and SLE flares were associated with the risk of APOs., Competing Interests: The authors have no conflicts of interests to disclose., (Copyright © 2021 the Author(s).

Objective: To investigate the factors associated with discordance between patient and physician on the presence of a gout flare., Methods: Patients' self-reports of current gout flares were assessed with the question, 'Are you having a gout flare today?' which was then compared with a concurrent, blinded, physician's assessment. Based on agreement or disagreement with physicians on the presence of a gout flare, flares were divided into concordant and discordant groups, respectively. Within the discordant group, two subgroups-patient-reported flare but the physician disagreed and physician-reported flare but the patient disagreed-were identified. The factors associated with discordance were analysed with multivariable logistic regression analysis., Results: Of 268 gout flares, 81 (30.2%) flares were discordant, with either patient or physician disagreeing on the presence of a flare. Of the discordant flares, in 57 (70.4%) the patient reported a flare but the physician disagreed. In multivariable logistic regression analysis adjusted for demographics, disagreement among patients and physicians on the presence of a gout flare was associated with lower pain scores at rest [odds ratio (OR) for each point increase on 0-10 point pain scale 0.81 (95% Wald CI 0.73, 0.90), P < 0.0001] and less presence of joint swelling [OR 0.24 (95% CI 0.10, 0.61), P = 0.003] or joint warmth [OR 0.39 (95% CI 0.20, 0.75), P = 0.005]., Conclusion: Although patients and physicians generally agree about the presence of gout flare, discordance may occur in the setting of low pain scores and in the absence of swollen or warm joints., (© The Author(s) 2020.

Background: Studies have shown that a low serum uric acid (SUA) level associates with Parkinson's disease (PD), but many of them did not exclude patients with impaired renal function. Studies on the association between serum bilirubin level and PD also are limited. This study determined the association between SUA level, SUA/serum creatinine (SCr) ratio and serum bilirubin levels in PD patients with normal renal and liver functions., Methods: The PD patients from a neurological clinic, and the controls from the club for the elderly, were recruited into this study. The PD stage and motor and non-motor function were determined by the Hoehn-Yahr (H&Y) scale and unified Parkinson's disease rating scale (UPDRS), respectively., Results: Sixty-one PD patients and 135 controls participated. The SUA/SCr ratio, but not SUA, was significantly lower in the PD patients than in the controls (4.12 ± 0.90 vs. 4.59 ± 1.04, P = 0.003). Serum total bilirubin (TB) and indirect bilirubin (IDB) were significantly higher in the PD patients (7.92 ± 3.67 µmol/L vs. 6.59 ± 2.78 µmol/L, P = 0.003 and 4.52 ± 2.48 µmol/L vs. 3.26 ± 1.82 µmol/L, P < 0.001), respectively. Serum TB and IDB, but not SUA or SUA/SCr ratio, were associated negatively with PD stages (P = 0.010 and P = 0.014, respectively). There was no association between TB, IDB, SUA or SUA/SCr ratio and PD disease duration or motor subtypes. No significant correlation was found between SUA or SUA/SCr ratio, serum TB and IDB., Conclusion: The SUA/SCr ratio is more sensitive than SUA in determining their association with PD. The high serum TB and IDB levels in PD patients compared with the controls suggest that serum bilirubin might play a role in the pathogenesis of PD. However, the lack of association between SUA or the SUA/SCr ratio and serum TB or IDB suggests that these two biomarkers play a different role in the etiopathogenesis of PD., Competing Interests: None to declare., (Copyright 2020, Songsomboon et al.)

Aims: To investigate susceptible human leukocyte antigen (HLA) alleles and their associations with clinical features in Thai patients with Behçet's disease (BD)., Method: Eighteen HLA-A and 36 HLA-B alleles were determined in 42 Thai BD patients and 99 healthy controls (HCs) by reverse line blot assay, and reconfirmed by MICRO SSP assay., Results: The BD patients had significantly higher allele frequency (AF) of HLA-B*51 than the HCs (13.10% vs 5.05%, P = .025). The AF of HLA-A*26, -A*26:01 and -B*51:01 also was higher and almost reached statistical significance (5.59% vs 1.52%, P = .054, 5.95% vs 1.52%, P = .054 and 10.71% vs 4.04%, P = .051, respectively). However, the BD patients had significantly higher AF of either HLA-A*26:01 or -B*51:01 (16.67% vs 5.56%, P = .005), or -A*26:01 or -B*51X (19.05% vs 6.56%, P = .003). The AF of HLA-B*51:01 and -B*51X increased significantly in -A*26:01 non-carrier BD patients (12.16% vs 4.17%, P = .024 and 14.86% vs 5.21%, P = .019, respectively); and that of HLA-A*26:01 was significantly higher in -B*51X non-carrier BD patients (7.58% vs 1.67%, P = .034). HLA-B*51:01 associated significantly with the presence of posterior uveitis and visual impairment (18.18% vs 2.50%, P = .031 for both conditions). HLA-B*51:01 was not observed in BD patients with gastrointestinal involvement or arthritis. Furthermore, the AF of HLA-B*51:01 was significantly higher in HLA-A*26:01 non-carrier BD patients without arthritis (17.30% vs 0%, P = .050)., Conclusion: HLA-B*51:01 was a susceptible allele for Thai BD patients, and associated with posterior uveitis and visual impairment. HLA-A*26:01 was another susceptible allele in HLA-B*51X non-carrier patients. The protective effect of HLA-B*51:01 on arthritis needs further investigation., (© 2020 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.)

Background: The utility of generic health-related quality of life (HRQoL) questionnaires in patients with systemic lupus erythematosus (SLE) is uncertain. We compared the performance of generic (SF36) and specific (SLEQOL) HRQoL surveys by examining their associations with the Global Rating of Change (GRC) and SLE clinical indicators., Methods: The study included SLE patients who attended a single-center rheumatology clinic between 2013 and 2017. Patients completed both specific (SLEQOL) and generic (SF36) surveys and rated their GRC compared to the previous visit using a 7-point Likert scale on the same day of routine visits. Based on GRC scores, patients' change in HRQoL was categorized as "no change," "deterioration," or "improvement." Disease activity (SLEDAI-2K), flare, and lupus low disease activity state (LLDAS) were assessed at each visit, and organ damage (SDI) was determined annually. Pairwise correlations between SLEQOL and SF36 components were examined, and associations between GRC status and SLE disease indicators were compared using generalized estimating equations (GEE)., Results: Three hundred thirty-seven patients with 2062 visits were included in the analysis. SLEQOL correlated significantly with SF36. Patients reported improvements in HRQoL in 58%, deterioration in 15%, and "no change" in 27% of all visits. Compared to the "no change" group, mean SF36 and SLEQOL scores were significantly lower in the deterioration group and higher in the improvement group. The magnitude of changes observed with SLEQOL and SF36 in the deterioration and improvement groups was similar. Patients in LLDAS had significantly higher mean scores in both SLEQOL and SF36. In contrast, patients with active disease, especially those with cutaneous, renal, central nervous system, and musculoskeletal activity, had significantly lower SLEQOL and SF36. Flare and organ damage were also associated with lower SLEQOL and SF36-PCS (physical component) but not with SF36-MCS (mental component)., Conclusion: SLEQOL and SF36 similarly describe HRQoL in SLE. Both instruments demonstrated strong associations with GRC-based deterioration or improvement as well as SLE disease status. LLDAS was associated with improved HRQoL.

Background: Evaluating the contribution of glucocorticoid use to organ damage in systemic lupus erythematosus is confounded by glucocorticoid use in active disease. We sought to determine the independence of the contribution of glucocorticoid use to damage accrual from associations with disease activity by analysing patients without measurable disease activity., Methods: Patients (age >18 years) who met the criteria for systemic lupus erythematosus were recruited from 13 centres in Australia, Indonesia, Japan, Malaysia, the Philippines, Singapore, Taiwan, and Thailand, and followed longitudinally. Disease activity (Systemic Lupus Erythematosus Disease Activity Index 2000 [SLEDAI-2K] and Physician Global Assessment [PGA] scores) and treatment details were recorded at each visit (at least once every 6 months), and organ damage measured annually according to the Systemic Lupus International Collaborating Clinics Damage Index (SDI). Glucocorticoid use during the study period was recorded as any exposure to prednisolone, cumulative prednisolone exposure, and time-adjusted mean daily prednisolone dose. Multivariate survival analyses were used to examine time-dependent associations of glucocorticoid use with damage accrual (defined as an increase of ≥1 on SDI). A SLEDAI-2K score of 0 was taken to indicate the absence of clinical and serological disease activity; a subset of patients without disease activity during the study were defined by a time-adjusted mean SLEDAI-2K (AMS) score of 0., Findings: Between May 1, 2013, and Dec 31, 2016, 1707 patients were recruited. Over a median observation period of 2·2 years (IQR 1·5-3·0), damage accrual events were observed in 255 (14·9%) patients. 1405 (82·3%) of patients were exposed to prednisolone, with a median time-adjusted mean prednisolone dose of 5·0 mg/day (IQR 1·9-8·8). As SLEDAI-2K and PGA scores were highly correlated, two multivariable models were set, each including one of these two variables. In the model including AMS score, baseline SDI damage (SDI >0) was independently associated with damage accrual (HR 1·32 [95% CI 1·01-1·73], p=0·0427). In the other model, time-adjusted mean PGA score was independently associated with damage accrual (1·05 [1·02-1·08], p=0·0012). In both models, factors independently associated with damage accrual included time-adjusted mean prednisolone dose, age at enrolment, and ethnicity (Asian vs non-Asians). 157 (9·2%) patients had an AMS score of 0 (no disease activity), among whom 103 (65·6%) had glucocorticoid exposure and the median time-adjusted mean prednisolone dose was 2·0 mg/day (IQR 0·0-5·0). Accrual of irreversible organ damage occurred in 21 (13·4%) of these patients and was independently associated with time-adjusted mean prednisolone dose (HR 1·14 [95% CI 1·03-1·26], p=0·0117), time-adjusted mean PGA score (1·13 [1·03-1·23], p=0·0144), and age at enrolment (1·04 [1·01-1·07], p=0·0061), but not baseline SDI damage (0·94 [0·43-2·06], p=0·8675)., Interpretation: Glucocorticoid use contributes to damage accrual in systemic lupus erythematosus independently of the presence of clinical or serological disease activity., Funding: UCB Pharma, GlaxoSmithKline, Janssen, Bristol-Myers Squibb, and AstraZeneca (to the Asia-Pacific Lupus Collaboration)., (Copyright © 2020 Elsevier Ltd.

Objective: There is a lack of standardisation in the terminology used to describe gout. The aim of this project was to develop a consensus statement describing the recommended nomenclature for disease states of gout., Methods: A content analysis of gout-related articles from rheumatology and general internal medicine journals published over a 5-year period identified potential disease states and the labels commonly assigned to them. Based on these findings, experts in gout were invited to participate in a Delphi exercise and face-to-face consensus meeting to reach agreement on disease state labels and definitions., Results: The content analysis identified 13 unique disease states and a total of 63 unique labels. The Delphi exercise (n=76 respondents) and face-to-face meeting (n=35 attendees) established consensus agreement for eight disease state labels and definitions. The agreed labels were as follows: 'asymptomatic hyperuricaemia', 'asymptomatic monosodium urate crystal deposition', 'asymptomatic hyperuricaemia with monosodium urate crystal deposition', 'gout', 'tophaceous gout', 'erosive gout', 'first gout flare' and 'recurrent gout flares'. There was consensus agreement that the label 'gout' should be restricted to current or prior clinically evident disease caused by monosodium urate crystal deposition (gout flare, chronic gouty arthritis or subcutaneous tophus)., Conclusion: Consensus agreement has been established for the labels and definitions of eight gout disease states, including 'gout' itself. The Gout, Hyperuricaemia and Crystal-Associated Disease Network recommends the use of these labels when describing disease states of gout in research and clinical practice., Competing Interests: Competing interests: AKT has received speaking fees and honoraria for advisory boards from Berlin Chemie Menarini, Novartis, Grünenthal and AstraZeneca.
