The Systemic Lupus International Collaborating Clinics (SLICC), American College of Rheumatology (ACR), and the Lupus Foundation of America are developing a revised systemic lupus erythematosus (SLE) damage index (the SLICC/ACR Damage Index [SDI]). Shifts in the concept of damage in SLE have occurred with new insights into disease manifestations, diagnostics, and therapy. We evaluated contemporary constructs in SLE damage to inform development of the revised SDI.We conducted a 3-part qualitative study of international SLE experts. Facilitated small groups evaluated the construct underlying the concept of damage in SLE. A consensus meeting using nominal group technique was conducted to achieve agreement on aspects of the conceptual framework and scope of the revised damage index. The framework was finally reviewed and agreed upon by the entire group.Fifty participants from 13 countries were included. The 8 thematic clusters underlying the construct of SLE damage were purpose, items, weighting, reversibility, impact, time frame, attribution, and perspective. The revised SDI will be a discriminative index to measure morbidity in SLE, independent of activity or impact on the patient, and should be related to mortality. The SDI is primarily intended for research purposes and should take a life-course approach. Damage can occur before a diagnosis of SLE but should be attributable to SLE. Damage to an organ is irreversible, but the functional consequences on that organ may improve over time through physiological adaptation or treatment.We identified shifts in the paradigm of SLE damage and developed a unifying conceptual framework. These data form the groundwork for the next phases of SDI development.

Background: Systemic lupus erythematosus (SLE) is associated with clinical burden for the patient and organ damage. The development of therapies for SLE has been constrained by clinical and biologic heterogeneity. These represent challenges in clinical trial design and endpoint selection. Objective: To identify the most relevant descriptors for efficacy, endpoints, disease activity, organ damage, quality of life (QoL), and Patient Reported Outcome Measures (PROMs) in the treatment of SLE. Methods: A Delphi study was conducted using a national expert panel of clinicians in the treatment of SLE. A steering committee composed of 3 opinion leaders with deep expertise in SLE treatment was defined. The steering committee analyzed and appraised the evidence, designed the Delphi study, defined the statements, and analyzed the expert panel responses. A 2-round Delphi survey was conducted. Participants were asked to rate the statements using a five-point Likert scale. Results: Nine experts participated in the Delphi survey. After the two rounds, the consensus was reached on 18 of the 23 statements: 2 statements were included in the “efficacy” domain, 2 in the “glucocorticoid-sparing” domain, 2 in the “endpoint evaluation” domain, 4 in the “score” domain, 1 in the “disease activity” domain, 1 in the “organ damage” domain, 1 in the “QoL” domain, 2 in the “PROMs” domain, 1 in the “AIFA monitoring” domain and 2 in the “extra” domain. No statements reached consensus within the “onset” domain. Conclusion: In this Delphi study, 18 statements across 11 domains were agreed upon for the treatment of SLE.

Calcification of Joints and Arteries (CALJA) is a rare disease that leads to chronic arthritis and lower limb claudication due to hydroxyapatite crystal deposition. The disease is caused by mutations in the 5-nucleotidase (NT5E) gene, which is responsible for pyrophosphate metabolism. Only 23 cases have been described so far. In this case report, we describe a new case of CALJA and provide a literature review. A 65-year-old woman was referred to the Rheumatology Unit with the diagnosis of seronegative oligo-arthritis. She complained of lower limb claudication, which was becoming progressively worse. Doppler ultrasound revealed bilateral obliteration of the popliteal and femoral arteries, and X-rays of the knees, hands, and feet showed extensive periarticular calcific deposits. The results of the NT5E gene analysis were positive for an inactivating variant, leading to the diagnosis of CALJA. The clinical features of CALJA are caused by hydroxyapatite crystal deposition at the periarticular and vascular levels due to abnormalities of pyrophosphate metabolism. Currently, no specific treatment is available, although a trial on the use of etidronate is ongoing. Patients with CALJA are often treated with immunosuppressant agents in the suspect of inflammatory rheumatologic diseases. Our case is the first in which clinical symptoms and a steady increase of inflammatory markers improved only after colchicine therapy initiation. It is crucial for the rheumatologist to recognize the features CALJA and keep it in mind in the differential diagnosis of patients with lower limb arterial insufficiency and arthritis or early osteoarthritis with joint calcification.

Objectives To describe phenotypes and outcomes of extra-renal flares in SLE, to identify clusters of extra-renal flares based on baseline features, and to develop a machine learning (ML) tool capable of predicting ‘difficult to treat’ (D2T) flares. Methods Extra-renal flares that occurred in our cohort over the last five years with at least one year of follow-up were included. Baseline clinical variables were described and flares assigned to clusters. Attainment of remission and low disease activity state (LLDAS) at 12 months were compared. Flares were then considered ‘D2T’ in case of non-attainment of LLDAS at 6 and 12 months. Baseline features were used to train a ML model able to predict future D2T-flares, at admission. Traditional approaches were then compared with informatic techniques. Results Among 420 SLE patients of the cohort, 114 flares occurred between 2015 and 2021; 79 extra-renal flares, predominantly mucocutaneous (24.1%) and musculoskeletal (45.6%), were considered. After 12 months, 79.4% and 49.4% were in LLDAS and in remission, respectively, while 17 flares were classified as D2T (21.5%); D2T flares received a higher cumulative and daily dose of glucocorticoids. Among the clusters, cluster ‘D’ (mild-moderate flares with mucocutaneous manifestations in patients with history of skin involvement) was associated with the lowest rate of remission. Among clinical data, not being on LLDAS at 3 months was the unique independent predictor of D2T flares. Conclusions Our clusterization well separates extra-renal flares according to their baseline features and may propose a new identification standard. D2T flares, especially refractory skin manifestations, are frequent in SLE and represent an unmet need in the management of the disease as they are associated with higher glucocorticoid (GC) dosage and risk of damage accrual. Our ML model could help in the early identification of D2T flares, flagging them to elevate the attention threshold at admission.

This case report describes 2 women with severe and refractory discoid lupus erythematosus that was treated with anifrolumab.

Autoimmune rheumatic diseases (ARD) can affect women and men during fertile age, therefore reproductive health is a priority issue in rheumatology. Many topics need to be considered during preconception counselling: fertility, the impact of disease-related factors on pregnancy outcomes, the influence of pregnancy on disease activity, the compatibility of medications with pregnancy and breastfeeding. Risk stratification and individualized treatment approach elaborated by a multidisciplinary team minimize the risk of adverse pregnancy outcomes (APO). Research has been focused on identifying biomarkers that can be predictive of APO. Specifically, preeclampsia and hypertensive disorders of pregnancy tend to develop more frequently in women with ARD. Placental insufficiency can lead to intrauterine growth restriction and small-for-gestational age newborns. Such APO have been shown to be associated with maternal disease activity in different ARD. Therefore, a key message to be addressed to the woman wishing for a pregnancy and to her family is that treatment with compatible drugs is the best way to ensure maternal and fetal wellbeing. An increasing number of medications have entered the management of ARD, but data about their use in pregnancy and lactation are scarce. More information is needed for most biologic drugs and their biosimilars, and for the so-called small molecules, while there is sufficient evidence to recommend the use of TNF inhibitors if needed for keeping maternal disease under control. Other issues related to the reproductive journey have emerged as "unmet needs", such as sexual dysfunction, contraception, medically assisted reproduction techniques, long-term outcome of children, and they will be addressed in this review paper. Collaborative research has been instrumental to reach current knowledge and the future will bring novel insights thanks to pregnancy registries and prospective studies that have been established in several Countries and to their joint efforts in merging data.

ObjectiveThe aim of this work is to explore patient’ unmet needs of rare and complex rheumatic tissue diseases (rCTDs) patients during pregnancy and its planning by means of the narrative-based medicine (NBM) approach.MethodsA panel of nine rCTDs patients’ representatives was identified to codesign a survey aimed at collecting the stories of rCTD patients who had one or more pregnancies/miscarriages. The results of the survey and the stories collected were analysed and discussed with a panel of patients’ representatives to identify unmet needs, challenges and possible strategies to improve the care of rCTD patients.Results129 replies were collected, and 112 stories were analysed. Several unmet needs in the management of pregnancy in rCTDs were identified, such as fragmentation of care among different centres, lack of education and awareness on rCTD pregnancies among midwifes, obstetricians and gynaecologists. The lack of receiving appropriate information and education on rCTDs pregnancy was also highlighted by patients and their families. The need for a holistic approach and the availability specialised pregnancy clinics with a multidisciplinary organisation as well as the provision of psychological support during all the phases around pregnancy was considered also a priority.ConclusionThe adoption of the NBM approach enabled a direct identification of unmet needs, and a list of possible actions was elaborated to improve the care of rCTD patients and their families in future initiatives.

Sydenham’s chorea (SC) is a post-streptococcal autoimmune disorder of the central nervous system, and it is a major criterium for the diagnosis of acute rheumatic fever (ARF). SC typically improves in 12–15 weeks, but patients can be affected for years by persistence and recurrencies of both neurological and neuropsychiatric symptoms. We enrolled 48 patients with a previous diagnosis of ARF, with or without SC, in a national multicenter prospective study, to evaluate the presence of neuropsychiatric symptoms several years after SC’s onset. Our population was divided in a SC group (n = 21), consisting of patients who had SC, and a nSC group (n = 27), consisting of patients who had ARF without SC. Both groups were evaluated by the administration of 8 different neuropsychiatric tests. The Work and Social Adjustment Scale (WSAS) showed significantly (p = 0.021) higher alterations in the SC group than in the nSC group. Furthermore, 60.4% (n = 29) of the overall population experienced neuropsychiatric symptoms other than choreic movements at diagnosis and this finding was significantly more common (p = 0.00) in SC patients (95.2%) than in nSC patients (33.3%). The other neuropsychiatric tests also produced significant results, indicating that SC can exert a strong psychopathological impact on patients even years after its onset.

Mechanisms for the generation of anti-dsDNA autoantibodies are still not completely elucidated. One theory states that dsDNA interacts for mimicry with antibodies raised versus other antigens but molecular features for mimicry are unknown. Here we show that, at physiological acid-base balance, anti-Annexin A1 binds IgG2 dsDNA in a competitive and dose-dependent way with Annexin A1 and that the competition between the two molecules is null at pH 9. On the other hand, these findings also show that dsDNA and Annexin A1 interact with their respective antibodies on a strictly pH-dependent basis: in both cases, the binding was minimal at pH 4 and maximal at pH9-10. The anionic charge of dsDNA is mainly conferred by the numerous phosphatidic residues. The epitope binding site of Annexin A1 for anti-Annexin A1 IgG2 was here characterized as a string of 34 amino acids at the NH2 terminus, 10 of which are anionic. Circulating levels of anti-dsDNA and anti-Annexin A1 IgG2 antibodies were strongly correlated in patients with systemic lupus erythematosus (n 496) and lupus nephritis (n 425) stratified for age, sex, etc. These results show that dsDNA competes with Annexin A1 for the binding with anti-Annexin A1 IgG2 on a dose and charged mediated base, being able to display an inhibition up to 75%. This study provides the first demonstration that dsDNA may interact with antibodies raised versus other anionic molecules (anti-Annexin A1 IgG2) because of charge mimicry and this interaction may contribute to anti-dsDNA antibodies generation.

Here we describe the case of a 38-year-old man with a history of ischemic transient attacks and strokes from the age of 9 years, livedo reticularis, asymmetrical sensorimotor neuropathy, optic neuritis, testicular ischemia, digital ulcers, ulcerative colitis, and diastolic hypertension. Disease course was characterized by severe disease bouts treated with high-dose intravenous (IV) glucocorticoid (GC) pulse therapy, short periods of paucisymptomatic disease, and inability to taper GCs despite the use of traditional oral and IV immunosuppressants, interferon, and plasmapheresis.

Primary Sjögren's syndrome (pSS) is an autoimmune exocrinopathy classically presenting with sicca symptoms. Nonetheless, disease onset with extraglandular manifestations, including interstitial lung disease (ILD), is increasingly reported. However, studies investigating pSS patients presenting with ILD (pSS-ILD) are limited.Aim of this study was to better characterise the phenotype of pSS patients presenting with ILD in comparison to pSS patients with classicsicca-onset. We especially investigated whether the two groups differed in glandular involvement comparing functional, imaging andhistologic findings, as well as patient reported outcome (PRO).Consecutive newly diagnosed pSS patients, all fulfilling the ACR/EULAR 2016 criteria, were included in this cross-sectional study from September 2016 to October 2021. Presence of ILD at pSS diagnosis was defined based on clinical findings, imaging assessment and pulmonary function tests (PFT). In addition to functional tests, a minor salivary gland biopsy was performed in all cases, recording number of foci, focus score (FS) and GC-like structures. Salivary glands ultrasonography (SGUS) was graded using the OMERACT semiquantitative scoring system (0-3) based on parenchyma inhomogeneity. PRO including ESSPRI, OHIP and OSSDI were collected.Extraglandular clinical features and biological abnormalities included in the ESSDAI were recorded. Data were expressed as mean±SD for continuous variables and as absolute frequencies and percentages for categorical variables. Chi-Square test and Mann-Whitney U-test and ANOVA were performed for comparisons of categorical variables and continuous variables, respectively.We included 178 newly diagnosed pSS patients (F:M=158:20). ILD was the first pSS manifestation in 11 (6%) cases, 8 F and 3 M, with a median time from ILD onset to pSS diagnosis of 2 years (25-75 IQ 1-4.5). Of the 11 pSS-ILD patients, HRCT pattern was defined as NSIP in 4, UIP in 4, NSIP+OP in 2 and LIP in 1 patient. Dyspnoea on exertion or chronic cough were reported by 7/11 (63.6%) patients.In comparison to sicca-onset patients, pSS-ILD patients presented an older age at diagnosis (55±13 vs. 70±7, p= 0.001) and a higher ESSDAI (3.9±4.7 vs. 12.3±4.3, p=0.001), driven by the pulmonary domain. Regarding glandular involvement, pSS-ILD patients reported milder xeropthalmia (VAS 5.8±3.1 vs. 2.8±3.5, p=0.002) and significative lower scores in OSDI (35.6±24.9 vs. 15.3±22.9, p=0.04) and OHIP (4.8±4.4 vs. 1.4±3.8, p=0.04), despite no significant differences observed between the two groups in ocular tests and unstimulated salivary flow rate. With respect to histology, no significant differences were found in number of foci, FS and GC-like structures. We observed a significantly different distribution of the SGUS OMERACT score in the two groups: none of pSS-ILD patients presented a SGUS OMERACT score ≥2 in the submandibular glands (SG), in contrast to 41/132 (31.1%) of the patients in the classical sicca-onset group (p=0.03). Finally, no significant differences were observed between the two groups with respect to non-pulmonary extraglandular manifestations, serologic features and other biological parameters.ILD-onset pSS patients represent an atypical phenotypic subset, with less pronounced sialadenitis structural changes in salivary glands, and with sicca symptoms probably overshadowed by the respiratory disease.

Treat-to-target is a therapeutic approach based on adjustments to treatment at set intervals in order to achieve well-defined, clinically relevant targets. This approach has been successfully applied to many chronic conditions, and in rheumatology promising results have emerged for rheumatoid arthritis. For systemic lupus erythematosus (SLE), defining the most meaningful treatment targets has been challenging, due to disease complexity and heterogeneity. Control of disease activity, the reduction of damage accrual and the patient’s quality of life should be considered as the main targets in SLE, and several new drugs are emerging to achieve these targets. This review is focused on describing the target to achieve in SLE and the methods to do so, and it is also aimed at discussing if treat-to-target could be a promising approach also for this complex disease.

Background: To assess skin involvement in a cohort of patients with systemic sclerosis (SSc) by comparing results obtained from modified Rodnan skin score (mRSS), durometry and ultra-high frequency ultrasound (UHFUS). Methods: SSc patients were enrolled along with healthy controls (HC), assessing disease-specific characteristics. Five regions of interest were investigated in the non-dominant upper limb. Each patient underwent a rheumatological evaluation of the mRSS, dermatological measurement with a durometer, and radiological UHFUS assessment with a 70 MHz probe calculating the mean grayscale value (MGV). Results: Forty-seven SSc patients (87.2% female, mean age 56.4 years) and 15 HC comparable for age and sex were enrolled. Durometry showed a positive correlation with mRSS in most regions of interest (p = 0.025, ρ = 0.34 in mean). When performing UHFUS, SSc patients had a significantly thicker epidermal layer (p < 0.001) and lower epidermal MGV (p = 0.01) than HC in almost all the different regions of interest. Lower values of dermal MGV were found at the distal and intermediate phalanx (p < 0.01). No relationships were found between UHFUS results either with mRSS or durometry. Conclusions: UHFUS is an emergent tool for skin assessment in SSc, showing significant alterations concerning skin thickness and echogenicity when compared with HC. The lack of correlations between UHFUS and both mRSS and durometry suggests that these are not equivalent techniques but may represent complementary methods for a full non-invasive skin evaluation in SSc.

Aim. To assess the efficacy of belimumab in joint and skin manifestations in a nationwide cohort of patients with SLE. Methods. All patients with skin and joint involvement enrolled in the BeRLiSS cohort were considered. Belimumab (intravenous, 10 mg/kg) effectiveness in joint and skin manifestations was assessed by DAS28 and CLASI, respectively. Attainment and predictors of DAS28 remission (

ObjectiveSystemic sclerosis (SSc) is burdened by Raynaud phenomenon (RP) and digital ulcers (DUs), and sometimes standard vasoactive therapies are ineffective or contraindicated. Selexipag is an oral selective IP prostacyclin receptor agonist approved for the treatment of SSc-related pulmonary arterial hypertension. We aimed to evaluate the clinical and instrumental efficacy of selexipag in SSc digital vasculopathy.MethodsPatients with SSc with severe digital vasculopathy refractory or with contraindication to all other vasoactive therapies were administered selexipag. RP- and DU-related clinical outcomes were evaluated, and digital perfusion was assessed by laser speckle contrast analysis (LASCA), all at baseline and after 3 months.ResultsSelexipag was administered to 9 patients with SSc (66.6% female, mean age 52.3 [SD 16.6] yrs). One patient had to stop the drug because of adverse effects. After 3 months of selexipag administration, there was a significant reduction in RP daily episodes (P= 0.01) and RP mean duration (P= 0.04). The number of DUs decreased from 10 to 4 without reaching statistical significance. A significant improvement in mean perfusion of the fingers (P= 0.02) was observed with LASCA.ConclusionSelexipag showed good potential for the treatment of SSc digital vasculopathy. Our results are certainly preliminary, yet quite encouraging. New trials for the evaluation of selexipag efficacy in SSc digital vasculopathy are needed.

BackgroundSLE is an autoimmune disease that predominantly affects women. As most epidemiological and interventional studies are on populations with a clear female prevalence, the influence of gender in disease course, drug response and damage accrual is yet to be fully explored and comprehended.ObjectivesTo describe gender differences in disease course, comorbidities, use of medications and long-term outcomes of a large cohort of patients with SLE.MethodsRetrospective gender-based analysis of prospectively collected data from a monocentric cohort of Caucasian patients with SLE with at least 1 year of follow-up.Results417 patients were included, 51 men and 366 women. Men displayed a significantly higher median age at disease onset and diagnosis and a higher prevalence of late-onset SLE, serositis at disease onset, antiphospholipid syndrome (APS) and use of mycophenolate within the first year of disease. Women had a higher prevalence of haematological abnormalities, a higher cumulative exposure to azathioprine and higher cumulative dose of glucocorticoids at 5 years. Male patients had a shorter time to first damage item and a higher prevalence of damage at 1 and 5 years, but this association was no longer significant when late-onset patients were excluded. No differences were found in prevalence of childhood onset, delay between onset and diagnosis, time to renal involvement and histology, cumulative autoantibody positivity, number of flares and hospitalisations, median SLE Damage Index score, type of damage, age and time to first cardiovascular event, chronic kidney disease and death.ConclusionsIn our cohort, clinical manifestations and disease course were similar in male and female patients; however, male patients displayed higher prevalence of APS and early damage accrual probably due to the later disease onset. These data highlight the importance of an intensive follow-up, prevention and treatment of complications in this category of patients, especially in the first years of disease.

To perform a semiquantitative and quantitative analysis of interstitial lung disease (ILD), through computed tomography (CT), in different serological subgroups of idiopathic inflammatory myopathies (IIM) patients, to find radiologic and clinical differences of disease related to serology.This was a prospective study, which included 98 IIM patients, divided into serological subgroups: anti-aminoacyl-transfer-RNA-synthetases (anti-ARS) positive and myositis-specific autoantibodies (MSA) negative.For each baseline CT the total semiquantitative score of Warrick (WS) and the automated software (Computer-Aided Lung Informatics for Pathology Evaluation and Rating) quantitative scores interstitial lung disease % (ILD%) and vascular-related structure % (VRS%) were calculated. Pulmonary function tests included total lung capacity % (TLC%), forced vital capacity % (FVC%), and diffusing capacity of the lung for carbon monoxide % (DLCO%).Inverse correlations ( P0.001) between the radiologic scores and the functional scores DLCO% and TLC% were found, the most relevant being between ILD% and DLCO% (ρ=-0.590), VRS% and DLCO% (ρ=-0.549), and WS and DLCO% (ρ=-0.471).Positive correlations between ILD% and VRS% (ρ=0.916; P0.001), WS and ILD% (ρ=0.663; ρ0.001), and WS and VRS% (ρ=0.637; P0.001) were obtained.Statistically significant higher values of WS, ILD%, and VRS% were found in the anti-ARS group (WS=15; ILD%=11; VRS%=3.5) compared with the MSA negative one (WS=2.5; ILD%=0.84; VRS%=2.2).The nonspecific interstitial pneumonia pattern was dominant. No statistically significant differences emerged at pulmonary function tests.In this study, ILD in anti-ARS-positive and MSA-negative groups was defined through semiquantitative and quantitative analysis of lung CT. The inverse correlations between the radiologic scores and TLC% and DLCO% ( P0.001) confirm the role of lung CT in the evaluation of ILD in IIM.

Background/Aims People with inflammatory/autoimmune rheumatic and musculoskeletal diseases (I-RMDs) were excluded from Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) vaccine clinical development programmes; therefore, concerns regarding the safety and effectiveness of SARS-CoV-2 vaccines in this population still exist. Previous studies in people with I-RMDs were small albeit reassuring in terms of the incidence of I-RMD flares and adverse events. Our aim was to describe the safety of vaccines against SARS-CoV-2 in people with I-RMD. Methods Physician-reported registry of I-RMD and non-inflammatory RMD (NI-RMDs) patients vaccinated against SARS-CoV-2. From 5/Feb/2021 to 27/Jul/2021, we collected data on demographics, vaccination, RMD diagnosis, disease activity, immunomodulatory/immunosuppressive treatments, flares, adverse events (AEs) and SARS-CoV-2 breakthrough infections. Data were analysed descriptively. Results The study included 5121 participants from 30 countries, 90% with I-RMDs (n = 4604, 68% female, mean age 60.5 years) and 10% with NI-RMDs (n = 517, 77% female, mean age 71.4). Inflammatory joint diseases (58%), connective tissue diseases (18%) and vasculitis (12%) were the most frequent diagnostic groups; 54% received conventional synthetic disease-modifying anti-rheumatic drugs (DMARDs), 42% biologic DMARDs and 35% immunosuppressants. Most patients received the Pfizer/BioNTech vaccine (70%), 17% AstraZeneca/Oxford and 8% Moderna. In fully vaccinated cases, breakthrough infections were reported in 0.7% of I-RMD patients and 1.1% of NI-RMD patients. I-RMD flares were reported in 4.4% of cases (0.6% severe), 1.5% resulting in medication changes. AEs were reported in 37% of cases (37% I-RMD, 40% NI-RMD), serious AEs in 0.5% (0.4% I-RMD, 1.9% NI-RMD). Conclusion The safety profiles of SARS-CoV-2 vaccines in patients with I-RMD were reassuring, and comparable to patients with NI-RMDs. The majority of patients tolerated their vaccination well with rare reports of I-RMD flare and very rare reports of serious AEs. These findings should provide reassurance to rheumatologists and vaccine recipients, and promote confidence in SARS-CoV-2 vaccine safety in I-RMD patients. Disclosure P.M. Machado: None. S.

Aims of the studyTo analyze the prevalence of self-reported anxiety and depression in a monocentric cohort of patients with Systemic Lupus Erythematosus (SLE); to study the main determinants and the impact on quality of life (QoL).MethodsA cross-sectional observational study including adult outpatients with SLE. Demographic and clinical data were analyzed: indices of disease activity (SELENA-SLEDAI); damage (SLICC-DI); comorbidities and concomitant therapies. The definitions for remission (DORIS) and “Lupus Low Disease Activity State” (LLDAS) were applied. At enrollment, each patient completed the following questionnaires: SF-36, FACIT-Fatigue, Lupus Impact Tracker (LIT), Systemic Lupus Activity Questionnaire (SLAQ), and the Hospital Anxiety and Depression Scale (HADS) in order to self-assess anxiety and depression symptoms. The Student t-test and Chi2 tests were conducted for univariate analysis. The Spearman test was used for linear correlation between continuous data. Multivariate analysis was performed by multiple linear and logistic regression.ResultsOne hundred fifty-four consecutive patients with SLE were enrolled, the majority female and Caucasian with a mean age = 43.3 ± 13.7 years. 79.9% were in LLDAS or remission. 36.4% had a SDI > 1. 13.7% of patients had concomitant fibromyalgia. 37.4% had symptoms indicating anxiety and 25% of depression according to the HADS questionnaire. In the multivariate analysis, patients with active disease were significantly more anxious and depressed (p < 0.01) compared to patients in LLDAS or remission. Fibromyalgia and older age were independently associated with anxiety and depression, respectively (p < 0.05). Active skin involvement was significantly linked to depression (p < 0.05). Higher scores on the HADS questionnaire (higher levels of anxiety and depression) were found to be significantly linked to patients’ perception of higher disease activity and worse quality of life, irrespective of disease activity, age and fibromyalgia.ConclusionSymptoms of anxiety and depression are frequent in SLE patients, including outpatients with mild/moderate disease. Such symptoms have a significant negative impact on QoL and perception of disease activity, regardless of other factors. Moreover, disease activity, advanced age and fibromyalgia appear to be significantly linked to mood disorders. Assessing symptoms of the anxious-depressive spectrum in patients with SLE could lead to improvement in patients’ perception of health status and quality of life.

ObjectiveTo use bioelectrical impedance vector analysis (BIVA) in a cohort of patients with systemic sclerosis (SSc) in order to assess their nutritional status in comparison to other groups of patients and to find any correlation with clinical characteristics and outcome of the disease.MethodsWe retrospectively collected data from 50 SSc patients who underwent BIVA for clinical suspicion of malnutrition and compared them with patients affected by other chronic autoimmune rheumatic diseases (OCAD, n = 27) and those who were only symptomatic of malnutrition but without autoimmune features (n = 15), and with 50 healthy controls (HC).ResultsPatients with SSc presented significantly lower values of phase angle (PhA), basal metabolic rate (BMR), and body cellular mass (BCM), and an increase in extracellular water (ECW; P < 0.01 for all) than HC; instead, there were no significant differences for BMI. No significant differences were found between SSc and OCAD. Among patients with SSc, age directly correlated with ECW (ρ = 0.342, P = 0.015) and inversely with PhA (ρ = –0.366, P = 0.009). Female sex, anemia, hypoalbuminemia, reflux, and early satiety/abdominal distension associated with relevant alterations in BIVA results. BIVA variables were significantly different when cardiopulmonary and microvascular involvement was present. Four patients died during the study: they had significantly (P ≤ 0.01) lower PhA, BMR, and BCM, with an increased ECW.ConclusionBIVA, unlike BMI, allowed an accurate characterization of SSc patients at risk of malnutrition, correlating with serological malnutrition markers, with SSc-specific organ manifestations (cardiopulmonary involvement and microvascular damage), and with mortality. BIVA variables might represent a surrogate marker of damage accrual that leads to malnutrition, thus playing a leading role in the prognostic stratification of SSc patients.

ObjectivePrevious research on coping strategies of patients with SLE showed that there are no absolute adaptive or maladaptive strategies and that the range of potential coping strategies is large and heterogeneous. In this paper, we aimed to identify, in a large sample of patients with SLE (N=3222), the most frequent words used by patients to describe their coping strategies, to group them into significant themes and to test their possible association with specific patient characteristics.MethodsOur analyses were based on the data set of the European survey ‘Living with Lupus in 2020’ (N=3222). Through the T-LAB software, we analysed the answers that adult participants gave to an open-ended question about how they cope with the disease. We identified the most frequent words, and with hierarchical cluster analysis we grouped them into semantic clusters (ie, themes) that were characterised by specific patterns of words. Finally, we tested the possible association between clusters and illustrative variables (sociodemographics, disease characteristics, quality of life).ResultsFive coping strategies were identified, each of them constituting an important percentage of the total word occurrences: positive attitude (22.58%), social support (25.46%), medical treatments (10.77%), healthy habits (20.74%) and avoid stress (20.45%). Each strategy was statistically associated with specific patient characteristics, such as age and organ involvement.ConclusionsLearning to adapt to a lifetime of having SLE may require replacing old coping strategies with more effective ones. Investigating patients’ coping strategies in relation to different patient characteristics represents a useful starting point for developing more targeted and efficacious interventions.

ObjectiveTo map existing organizational care pathways in clinical centers of expertise that care for pregnant women affected by rare and complex connective tissue diseases (rcCTDs).MethodsAn international working group composed of experts in the field of pregnancy in rcCTDs co-designed a survey focused on organizational aspects related to the patient's pathway before, during, and after pregnancy. The survey was distributed to subject experts through referral sampling.ResultsAnswers were collected from 69 centers in 21 countries. Patients with systemic lupus erythematosus and/or antiphospholipid syndrome were followed by more than 90% of centers, whereas those with disorders such as IgG4-related diseases were rarely covered. In the majority of centers, a multidisciplinary team was involved, including an obstetrician/gynecologist in 91.3% of cases and other healthcare professionals less frequently. Respondents indicated that 96% of the centers provided routine pre-pregnancy care, whereas the number of patient visits during pregnancy varied across centers. A formalized care pathway was described in 49.2% of centers, and 20.3% of centers had a predefined protocol for the monitoring of pregnant patients. Access to therapies during pregnancy also was heterogeneous among different centers.ConclusionIn international referral centers, a high level of care is provided to patients with rcCTDs before, during, and after pregnancy. No significant discrepancies were found between European and non-European countries. However, this work highlights a potential benefit to streamlining the care approaches across countries to optimize pregnancy and perinatal outcomes among patients with rcCTDs.

© Copyright Clinical and Experimental Rheumatology 2022, Objectives: The purpose of this study was to review the frequency and clinical presentation of the rarest clinical manifestations of systemic lupus erythematosus (SLE). Methods: A list of 6 rare SLE manifestations were defined: gastrointestinal, liver, pulmonary, cardiac, ocular and neurological manifestations. Each topic was assigned to a pair of authors to perform a literature search and article review. Results: In total, 149 articles were included in the literature review: 37 for gastrointestinal manifestations, 6 for liver manifestations, 27 for pulmonary manifestations, 50 for cardiac manifestations, 16 for ocular manifestations, 13 for neurological manifestations. Gastrointestinal disorders included several clinical presentations with variable frequency (from 0.5% to 10.7% of the cases); liver involvement included lupus-related hepatitis (9.3%) and autoimmune hepatitis (2.3%). The rarest pulmonary manifestations identified were shrinking lung syndrome, described in 1.5% of patients, while interstitial lung disease and lupus pneumonia were reported in 4% and 3% of patients respectively. Myocarditis and pulmonary hypertension were also rarely described in SLE patients although ranging from 0.4-16% and 1-14% respectively, depending on the methodology used for its identification. Ocular manifestations in SLE included some rare manifestations (reported in less than 5% of patients) and lupus retinopathy that is described in 1.2-28.8% of patients depending on methods of ascertainment. Aseptic meningitis and chorea were also confirmed as very rare manifestations being reported in less than 1% and in 0.3-2.4% of cases respectively. Conclusions: The results of this literature review provide the basis for a better understanding of some less-known manifestations of SLE and for stressing the need for a higher awareness in diagnostic and therapeutic protocols regarding these rare disease aspects.

To provide a full characterization of proper palmar digital arteries (PPDA) in systemic sclerosis (SSc) with ultra-high frequency ultrasound (UHFUS), and to investigate possible relationships between digital macroangiopathy and microangiopathy.SSc patients without active digital ulcers and healthy controls (HC) were enrolled. Each subject underwent UHFUS 70 MHz evaluation of PPDA from II to V fingers bilaterally, searching for vessel occlusion and measuring the thickness of the three arterial layers and the systolic-diastolic excursion range. Microcirculation was investigated with capillaroscopy and laser speckle contrast analysis (LASCA).Forty-six SSc patients (87% female, mean age 55.5 years) and 15 HC comparable for age and sex were enrolled. UHFUS in SSc revealed the occlusion of 124 (16.8%) PPDA, whereas in HC they were all patent. Considering a finger with at least one PPDA occluded as ultrasonographically pathological, 67.4% patients presented ≥1 pathological fingers. All three arterial layers were significantly thicker and excursion range significantly reduced in SSc than in HC (p0.001 for all). Seventy-three percent of fingers previously affected by digital ulcers, were ultrasonographically pathological. Disease duration was directly correlated to the thickness of all three arterial layers. No significant correlations emerged between capillaroscopy or LASCA findings and UHFUS features.UHFUS allows the characterization of vasculopathic involvement of PPDA in SSc, also showing subclinical vasculopathy. The lack of correlations between UHFUS and capillaroscopy or LASCA likely mirrors non-overlapping vasculopathic processes. UHFUS evaluation of PPDA emerges as complementary to microcirculation assessment for a more accurate and complete characterization of SSc vasculopathy.

In patients with systemic sclerosis (SSc) the perfusion of the fingers shows an alteration of the physiological proximal-distal gradient (PDG). The aim of this study is to provide a generalizable definition of PDG, applying it in a cohort of SSc patients and healthy controls (HC) using laser speckle contrast analysis (LASCA).Adult consecutive SSc patients and HC were enrolled. Peripheral blood perfusion of the hands was evaluated by LASCA, subsequently obtaining 3 different regions of interest: from the distal interphalangeal joint to the fingertip (DIST), from the metacarpophalangeal joint to the distal interphalangeal joint (PROX), and of the whole finger (TOT). A PDG formula independent of both intra- and inter-personal factors was then built. The PDG formula so obtained was: [(DIST × 2.63) - PROX]/TOT.Ninety-four SSc patients (79.8% female, mean age 58.7 years) were enrolled. Applying the PDG formula, SSc patients revealed mean PDG values significantly lower than HC (1.82 ± 0.44 PU vs 2.70 ± 0.38 PU; p 0.0001). Patients with a previous history of digital ulcers presented significant lower PDG values (p = 0.002). The ROC curve analysis identified in 2.28 PU the best PDG cut-off value between SSc and HC, with 86% sensibility and 90% specificity.This study provided a PDG formula generalizable to all kind of subjects, applying it in SSc with great sensibility and specificity using LASCA, the best non-invasive imaging technique for the dynamical evaluation of peripheral perfusion. LASCA-PDG appears also as a tool able to identify a subclinical microangiopathic impairment.

ObjectiveWe conducted an international survey of patients with SLE to assess their access, preference and trust in various health information sources pre-COVID-19 and during the COVID-19 pandemic.MethodsPatients with SLE were recruited from 18 observational cohorts, and patients self-reporting SLE were recruited through five advocacy organisations. Respondents completed an online survey from June 2020 to December 2021 regarding the sources of health information they accessed in the 12 months preceding (pre-11 March 2020) and during (post-11 March 2020) the pandemic. Multivariable logistic regressions assessed factors associated with accessing news and social media post-11 March 2020, and self-reporting negative impacts from health information accessed through these sources.ResultsSurveys were completed by 2111 respondents; 92.8% were female, 76.6% had postsecondary education, mean (SD) age was 48.8 (14.0) years. Lupus specialists and family physicians were the most preferred sources pre-11 March 2020 and post-11 March 2020, yet were accessed less frequently (specialists: 78.5% pre vs 70.2% post, difference −8.3%, 95% CI −10.2% to −6.5%; family physicians: 57.1% pre vs 50.0% post, difference −7.1%, 95% CI −9.2% to −5.0%), while news (53.2% pre vs 62.1% post, difference 8.9%, 95% CI 6.7% to 11.0%) and social media (38.2% pre vs 40.6% post, difference 2.4%, 95% CI 0.7% to 4.2%) were accessed more frequently post-11 March 2020 vs pre-11 March 2020. 17.2% of respondents reported negative impacts from information accessed through news/social media. Those outside Canada, older respondents or with postsecondary education were more likely to access news media. Those in Asia, Latin America or younger respondents were more likely to access social media. Those in Asia, older respondents, males or with postsecondary education in Canada, Asia or the USA were less likely to be negatively impacted.ConclusionsPhysicians, the most preferred and trusted sources, were accessed less frequently, while news and social media, less trusted sources, were accessed more frequently post-11 March 2020 vs pre-11 March 2020. Increasing accessibility to physicians, in person and virtually, may help reduce the consequences of accessing misinformation/disinformation.

Digital ulcers (DUs) represent one major burden for patients with systemic sclerosis (SSc). The objectives of our study were to evaluate blood flow in SSc-DUs with laser speckle contrast analysis (LASCA) and to correlate the skin perfusion to clinical and laboratory data.Forty DUs in 31 consecutive patients with SSc according to 2013 ACR/EULAR criteria (20 with limited cutaneous disease, 3 males) were prospectively examined with LASCA. Clinical and laboratory data were collected at the same time. DUs were classified according to clinical features and presence of infection.At LASCA analysis, patients with diffuse SSc had lower mean values of blood flow compared with those with limited disease at the finger affected by DUs (88.80 vs 44.40, p = 0.036) and at the periulcer area (p = 0.041). The presence of infection was associated to a higher flow at the finger with DU (103.02 vs 58.05 p = 0.04), at the level of ulcer (217.63 vs 67.15, p 0.001), and at the periulcer area (p = 0.001). The ratio between the blood flow at the ulcer area and the finger base (UA/FB) showed a bimodal trend in patients with infected DUs and in those without infections. Infection was positive correlated to the time of healing (HT) (r = 0.648, p = 0.023), while in DUs without infection a negative correlation to HT (r = - 0.46, p = 0.015) was identified.This study demonstrates for the first time that the UA/FB ratio may predict the healing time of DUs in SSc patients and may be crucial for the prognostic stratification of patients. Infection remains one of the main predictors of DU healing.Key Points• The prognostic value of laser speckle contrast analysis (LASCA) in patients with digital ulcers (DUs) in systemic sclerosis remains to be clarified.• LASCA may be able to predict the haling time of the digital ulcers.• The presence of infection of the wound bed may greatly influence the LASCA parameters and the healing time of the digital ulcer.

Background/objectives The European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) 2019 classification criteria for systemic lupus erythematosus system showed high specificity, while attaining also high sensitivity. We hereby analysed the performance of the individual criteria items and their contribution to the overall performance of the criteria. Methods We combined the EULAR/ACR derivation and validation cohorts for a total of 1197 systemic lupus erythematosus (SLE) and n=1074 non-SLE patients with a variety of conditions mimicking SLE, such as other autoimmune diseases, and calculated the sensitivity and specificity for antinuclear antibodies (ANA) and the 23 specific criteria items. We also tested performance omitting the EULAR/ACR criteria attribution rule, which defines that items are only counted if not more likely explained by a cause other than SLE. Results Positive ANA, the new entry criterion, was 99.5% sensitive, but only 19.4% specific, against a non-SLE population that included other inflammatory rheumatic, infectious, malignant and metabolic diseases. The specific criteria items were highly variable in sensitivity (from 0.42% for delirium and 1.84% for psychosis to 75.6% for antibodies to double-stranded DNA), but their specificity was uniformly high, with low C3 or C4 (83.0%) and leucopenia Conclusions Changing the position of the highly sensitive, non-specific ANA to an entry criterion and the attribution rule resulted in a specificity of >80% for all items, explaining the higher overall specificity of the criteria set.

During the COVID-19 pandemic, the need to provide high-level care for a large number of patients with COVID-19 has affected resourcing for, and limited the routine care of, all other conditions. The impact of this health emergency is particularly relevant in the rare connective tissue diseases (rCTDs) communities, as discussed in this Perspective article by the multi-stakeholder European Reference Network on Rare and Complex Connective Tissue and Musculoskeletal Diseases (ERN ReCONNET). The clinical, organizational and health economic challenges faced by health-care providers, institutions, patients and their families during the SARS-CoV-2 outbreak have demonstrated the importance of ensuring continuity of care in the management of rCTDs, including adequate diagnostics and monitoring protocols, and highlighted the need for a structured emergency strategy. The vulnerability of patients with rCTDs needs to be taken into account when planning future health policies, in preparation for not only the post-COVID era, but also any possible new health emergencies., In this Perspective article, members of the European Reference Network on Rare and Complex Connective Tissue and Musculoskeletal Diseases discuss clinical and organizational challenges in this community caused by the COVID-19 pandemic and what lessons might be learned for the future.

Objectives To determine whether disease remission or low disease activity state at the beginning of pregnancy in SLE patients is associated with better pregnancy outcome. Methods Pregnancies in SLE patients prospectively monitored by pregnancy clinics at four rheumatology centres were enrolled. Patient demographics and clinical information were collected at baseline (pregnancy visit before 8 weeks of gestation) including whether patients were in remission according to the Definition of Remission in SLE (DORIS) criteria and and/or Lupus Low Disease Activity State (LLDAS). Univariate and multivariate analysis were performed to determine predictors of disease flare and adverse pregnancy outcomes (APOs) including preeclampsia, preterm delivery, small for gestational age infant, intrauterine growth restriction and intrauterine fetal death. Results A total of 347 pregnancies were observed in 281 SLE patients. Excluding early pregnancy losses, 212 pregnancies (69.7%) occurred in patients who were in remission at baseline, 33 (10.9%) in patients in LLDAS, and the remainder in active patients. Seventy-three flares (24%) were observed during pregnancy or puerperium, and 105 (34.5%) APOs occurred. Multivariate analysis revealed that patients in disease remission or taking HCQ were less likely to have disease flare, while a history of LN increased the risk. The risk of APOs was increased in patients with shorter disease duration, while being on HCQ resulted a protective variable. An almost significant association between complete remission and a decreased risk of APOs was observed. Conclusions Prenatal planning with a firm treat-to-target goal of disease remission is an important strategy to reduce the risk of disease flares and severe obstetric complications in SLE pregnancies.

Immunological tolerance is a critical feature of the immune system; its loss might lead to an abnormal response of lymphocytes causing autoimmune diseases. One of the most important groups belonging to autoimmune disorders is the connective tissue diseases (CTD). CTD are classified among systemic rheumatic diseases and include pathologies such as systemic lupus erythematosus (SLE), and undifferentiated CTD (UCTD). In this study, we evaluated oxidative and genome damage in peripheral blood lymphocytes from patients with SLE and UCTD, further classified on the basis of disease activity and the presence/absence of a serological profile. Oxidative damage was evaluated in cell membrane using the fluorescent fatty acid analogue BODIPY581/591 C11. The percentage of oxidised lymphocytes in both SLE and UCTD patients was higher than in the control group, and the oxidative stress correlated positively with both disease activity and autoantibody profile. The γH2AX focus assay was used to quantify the presence of spontaneous double strand breaks (DSBs), and to assess the abilities of DSBs repair system after T cells were treated with mitomycin C (MMC). Subjects with these autoimmune disorders showed a higher number of γH2AX foci than healthy controls, but no correlation with diseases activity and presence of serological profile was observed. In addition, patients displayed an altered response to MMC-induced DSBs, which led their peripheral cells to greatly increase apoptosis. Taken together our results confirmed an interplay among oxidative stress, DNA damage and impaired DNA repair, which are directly correlated to the aggressiveness and clinical progression of the diseases. We propose the evaluation of these molecular markers to better characterise SLE and UCTD, aiming to improve the treatment plan and the quality of the patients’ life.

We evaluated the performance of the new criteria with regard to disease duration, sex and race/ethnicity, and compared its performance against the Systemic Lupus International Collaborating Clinics (SLICC) 2012 and ACR 1982/1997 criteria. METHODS: Twenty-one SLE centres from 16 countries submitted SLE cases and mimicking controls to form the validation cohort. The sensitivity and specificity of the EULAR/ACR 2019, SLICC 2012 and ACR 1982/1997 criteria were evaluated. RESULTS: The cohort consisted of female (n=1098), male (n=172), Asian (n=118), black (n=68), Hispanic (n=124) and white (n=941) patients; with an SLE duration of 1 to

European League Against Rheumatism and are jointly supporting multiphase development of systemic lupus erythematosus (SLE) classification criteria based on weighted criteria and a continuous probability scale. Prior steps included item generation, item reduction and hierarchical organisation of candidate criteria using an evidence-based approach. Our objectives were to determine relative weights using multicriteria decision analysis (MCDA) and to set a provisional threshold score for SLE classification. An SLE Expert Panel (8 European, 9 North American) submitted 164 real, unique cases with a wide range of SLE probability in a standardised format. Using the candidate criteria, experts scored and rank-ordered 20 representative cases. At an in-person meeting, experts reviewed inter-rater reliability of scoring, further refined criteria definitions and participated in an MCDA exercise. Based on expert consensus decisions on pairwise comparisons of criteria, 1000minds software calculated criteria weights and rank-ordered the remaining 144 cases based on their additive scores. The score of the lowest-ranked case for which complete expert consensus was achieved defined the provisional threshold classification score. Inter-rater reliability of scoring cases with the candidate criteria was good. MCDA involved 74 pairwise decisions and was repeated for the arthritis and mucocutaneous domains when the initial ranking of some cases did not match expert opinion. After criteria weights and additive scores were recalculated once, experts reached consensus for SLE classification for all cases scoring>83. Using an iterative process, the candidate criteria definitions were refined, preliminary weights were calculated and a provisional threshold score for SLE classification was determined.

Background One of the most important complications of lupus nephritis (LN) is the chronic kidney disease (CKD) development. Methods Multicenter retrospective observational study of SLE patients (ACR97) with biopsy proven LN attending to three South European Rheumatology departments in the last two decades. Variables: demographics; SLE-related, including global activity (SLEDAI-2K), renal flares, therapies, ACR response criteria and CKD. Statistical analysis: bivariate and multivariate analysis exploring factors associated to CKD. ROC curves and area under the curve were calculated to test each proteinuria level as predictor of long-term renal outcome. Results Seventy-six patients were included, mean age: 33 years; mean disease duration: 14 years; mean follow-up (since LN diagnosis): 8,5 years. LN class III, IV and V were present in 22%, 75% and 3% of the cases, respectively. Cyclophosphamide was the most used treatment to induce remission (55%). At 3, 6 and 12th months, the mean proteinuria was 2.3 g/24h, 1.53 g/24h, 1.1 g/24h, respectively (p In the logistic regression model, using genetic algorithms, we found that proteinuria at 6 months was significantly associated with CKD (OR:2.95; 95%CI 1.19,9.29, p=0.03). Hypertension and male sex were marginally associated (p=0.06, both). The optimal cut-off point of proteinuria at 6 months was 0.7 g/day, (sensitivity: 50%; specificity: 93%). Conclusions A considerable percentage of LN developed CKD. Proteinuria at 6 months was associated with CKD. An absolute level of proteinuria below 0.7 g/day measured at 6 months is the best predictor of long-term renal outcomes.

Background The attainment of remission and low disease activity (LLDAS) in SLE is associated with better outcomes. This study was aimed to test whether disease remission and LLDAS at the beginning of pregnancy are associated with better pregnancy outcomes. Methods A total of 85 pregnancies in 61 SLE patients prospectively followed at a single center were considered; 10 pregnancies ended in spontaneous abortion during the first trimester and were excluded from the analysis. Definitions of remission (according to DORIS criteria) and LLDAS were applied at the first pregnancy visit (7–8 weeks of gestational age). Disease flare was defined according to the SELENA-SLEDAI flare index. Obstetric complications included pretermprelabour rupture of membranes, preeclampsia, preterm delivery, SGA infant, IUGR, intrauterine fetal death (IUFD) and gestational diabetes. Results Characteristics of the cohort are detailed in table 1. In twenty-one cases (28%) we observed flare during pregnancy or puerperium. Two severe flares and 19 mild-moderate flares were recorded. Obstetric complications were observed in 31 cases (41%). The risk of disease flare during pregnancy was significantly lower in patients in LLDAS at the beginning of pregnancy with respect to active patients (OR 12.47, p Conclusions These data confirm that disease remission is one important predictor of pregnancy outcomes in SLE. While serology seems not to have a substantial role, a residual disease activity at conception might impact on pregnancy outcomes. Available definitions of remission and LLDAS could be valid treatment targets in the family planning perspective.

Background Supported by both the ACR and EULAR, the EULAR/ACR 2019 Classification Criteria for SLE employ positive ANA (ever) as an entry criterion and use a weighted scheme with values ranging from 2 to 10, for a classification cut-off of 10. Criteria items are attributed to SLE only if there is no more likely alternative diagnosis in the individual patients. Items are organized in domains, and only the highest ranking item within a domain is counted. These criteria have been validated in a cohort of 696 SLE patients and 574 non-SLE patients from a total of 21 centers, reaching an overall sensitivity of 96.1% and a specificity of 93.4%. To at least estimate the performance in groups underrepresented in the validation cohort of this transatlantic project, we analyzed this cohort for patient subsets with regard to sex, ethnicity, and disease duration. Methods The full EULAR/ACR 2019 classification criteria validation cohort was analyzed for female (n=1,098) and male (n=172) patients, Asian (n=118), Black (n=68), Hispanic (n=124) and White (n=941) patients, and patients with an SLE duration of less than 1 year (n=34), one to less than 3 years (n=196), 3 to less than 5 years (n=157), and 5 or more years (n=879). Sensitivity and specificity were calculated for the EULAR/ACR 2019 criteria, the SLICC 2012 criteria and the ACR 1997 criteria each. Results As shown in table 1, most of the point estimates for sensitivity and specificity in subsets lay within the 95% confidence intervals of the sensitivity and specificity of the EULAR/ACR 2019 criteria validation. In particular, sensitivity and specificity for all ethnic groups were within the confidence intervals or even higher. Formally, the sensitivity was slightly lower for male patients, corresponding to a higher specificity, but the male 95% confidence intervals (0.86–0.98 for sensitivity, 0.90–0.99 for specificity) overlapped. While sensitivity appeared independent of disease duration from year 1 on, sensitivity was only 89% in the first year of disease, identical to the SLICC criteria (89%) and numerically higher than the ACR criteria (56%), but all confidence intervals overlapped. Conclusion While not all subgroups of SLE patients in the validation cohort are of adequate size to fully explore the sensitivity and specificity of the EULAR/ACR 2019 SLE classification criteria in the respective subsets, the point estimates of sensitivity and specificity suggest that the new criteria perform at least reasonably well in all ethnic groups, in men and in early disease. Nevertheless, sensitivity and specificity should be independently validated in larger groups of Asian, Black and Hispanic patients, male patients and in early disease.

OBJECTIVE Systemic lupus erythematosus (SLE) presents with nonspecific signs and symptoms that are also found in other conditions. This study aimed to evaluate manifestations at disease onset and to compare early SLE manifestations to those of diseases mimicking SLE. METHODS Academic lupus centers in Asia, Europe, North America, and South America collected baseline data on patients who were referred to them during the previous 3 years for possible SLE and who had a symptom duration of

Objectives To systematically review the literature on the prevalence of Cognitive Dysfunction (CD) in SLE patients in studies that used a specified neuropsychological instrument. Methods This review was prepared with a protocol following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis-Protocols statement. Literature search in Ovid Medline, Embase, and Psyc INFO for articles on CD in adult SLE patients was conducted. Included studies were critically appraised (Newcastle-Ottawa Evaluation Scale) and the Pooled Prevalence (PP) of CD was studied for all instruments. The association between demographics and CD, the risk of CD in SLE compared to healthy subjects and patients with RA, and the course of CD over time were studied narratively whenever sufficient information was available. Result Of 8054 references, 670 were selected for detailed review and 78 were included in the final analysis. Comprehensive Battery (CB) was utilized in 35 studies in 2463 SLE patients and PP was 38% (95%; CI: 33–43%). The CD prevalence was higher in NPSLE [PP 39% (95% CI: 24–55%]. Automated Neuropsychological Assessment Metric (ANAM) was utilized in 7 studies in 438 patients (PP of CD 26% (95% CI: 12–42%). Other less frequently utilized tools were the Modified Mini–Mental State Exam (MMSE), Montreal Cognitive Assessment (MoCA), Controlled Oral Word Association Test (COWAT) and The Hopkins Verbal Learning Test-Revised (HVLT-R) and subjective tools and others. The relative risk for CD in SLE was greater when compared to RA and to healthy individuals; RR being 1.80 and 2.80, respectively. Information on demographics and its association with CD was very heterogeneous among studies. Conclusion Patients with lupus have a high prevalence of CD. The delay in diagnosis of CD is complex; although caregivers and patients express concerns about cognitive function, testing for CD often imposes administrative and cost burdens. There is an unmet need to identify the best screening, diagnostic metrics of CD. The assessment of cognitive function over time, and the association of demographics with CD, will require further research.
