Objective This study aimed to assess the efficacy and safety of intravenous ramosetron for pain relief in patients with fibromyalgia (FM) unresponsive to conventional treatments. Methods In this prospective, double-blind, placebo-controlled trial, 80 FM patients were randomly allocated to receive either placebo (n = 40) or ramosetron (n = 40) at a dosage of 0.3 mg/day intravenously for five consecutive days. The primary outcome was the reduction in pain intensity at the end of the treatment period, evaluated using a visual analogue scale (VAS). Secondary outcome measures included the FM Impact Questionnaire, Beck Depression Inventory (BDI), Multi-Dimensional Health Assessment Questionnaire (MDHAQ), EQ-5D and State-Trait Anxiety Inventory on days 5 (end of treatment), 7, 10 and 28. Safety was continuously monitored throughout the study. Results At the end of the treatment phase, the ramosetron group demonstrated a significantly greater reduction in VAS pain scores compared with the placebo group (1.18 ± 1.60 vs 0.54 ± 1.59, P < 0.05). Additionally, the ramosetron group exhibited significant improvements in BDI (4.42 ± 5.18 vs 1.33 ± 4.87, P < 0.05) and MDHAQ pain scale (0.37 ± 0.74 vs 0.04 ± 0.52, P < 0.05) scores. However, these improvements in pain VAS and BDI scores were not sustained through day 28. The safety profile of ramosetron was favorable, with gastrointestinal symptoms, particularly constipation, being the most commonly reported adverse events. Conclusions Intravenous administration of ramosetron provided safe and effective short-term relief of pain intensity in FM patients with inadequate response to standard treatments.

Background and Objectives: Hyperuricemia is associated with a variety of comorbidities. The objective of this study was to investigate the association between hyperuricemia and hearing impairment in Korean adults. Materials and Methods: Audiometric and laboratory test data from the 2019 to 2020 Korean National Health and Nutrition Examination Survey (KNHANES) were used for analysis. Hearing impairment was defined as a pure-tone average (0.5, 1, 2, 4 kHz) threshold level ≥ 41 decibels. The definition of hyperuricemia was different for males and females: >7 mg/dL for males vs. >6 mg/dL for females. Results: A total of 4857 (weight n = 17,990,725) subjects were analyzed. The mean age was 56.8 years old. The weighted prevalence was 12.1% for hyperuricemia and 2.5% for gout. The prevalence of hearing impairment was 13.4%. In the univariable analysis, hyperuricemia was significantly associated with hearing impairment. However, the diagnosis of gout was not associated with hearing impairment. In the multivariable analysis, hyperuricemia (odds ratios (OR): 1.41, 95% confidence interval [CI]: 1.03–1.92, p = 0.030) was associated with hearing impairment along with age (OR: 1.12, 95% CI: 1.10–1.14, p < 0.001), female sex (OR: 0.43, 95% CI: 0.34–0.64, p < 0.001), education (OR: 0.43, 95% CI: 0.30–0.63, p = 0.001), and occupational noise exposure (OR: 1.67, 95% CI: 1.25–2.22, p = 0.001). In the subgroup analysis, hyperuricemia was associated with hearing impairment in females (OR: 1.59, 95% CI: 1.02–2.48, p = 0.041) and the elderly aged 60 years or more (OR: 1.45, 95% CI: 1.05–1.99, p = 0.023). Conclusions: Hyperuricemia was independently associated with hearing impairment, especially in females and the elderly aged 60 years or more. [ABSTRACT FROM AUTHOR]

Aim: Coronavirus disease 2019 (COVID‐19) has been proposed as triggering autoimmunity. The aim of this study was to evaluate the presence and clinical significance of autoantibodies in patients with COVID‐19. Methods: We retrospectively collected data from 245 patients who were hospitalized for COVID‐19. All patients were tested for the presence of antinuclear antibody (ANA), rheumatoid factor (RF), anti‐citrullinated peptide antibody (ACPA), and anti‐cytoplasmic neutrophil antibody (ANCA). Risk factors for death and critical COVID‐19, defined as the need for invasive mechanical ventilation or extracorporeal membrane oxygenation, were analyzed. Results: Ninety (36.7%) patients tested positive for ANA, and 51 (20.8%) patients tested positive for RF. Three patients each (1.2%) tested positive for ACPA and ANCA. RF‐positive patients had higher rates of invasive mechanical ventilation and death than RF‐negative patients (70.6% vs 28.4%, P < 0.001 and 45.1% vs 18.6%, P < 0.001, respectively). Underlying lung disease, kidney disease, heart disease, quick COVID severity index (qCSI), and lactate dehydrogenase (LDH) were associated with in‐hospital death. RF (odds ratio [OR] 7.31, 95% CI 2.50–21.37, P < 0.001), qCSI (OR 1.42, 95% CI 1.19–1.69, P < 0.001), and LDH (OR 1.004, 95% CI 1.002–1.005, P < 0.001) were associated with critical COVID‐19. Combination of RF, qCSI, and LDH showed good prognostic value (area under the curve = 0.903, P < 0.001) for critical COVID‐19. Conclusions: ANA and RF were frequently detected in COVID‐19 patients. RF could be a risk factor for critical COVID‐19. The results of this study suggest immune dysfunction contributes to the complications of COVID‐19. [ABSTRACT FROM AUTHOR]

Aim: To evaluate clinical characteristics and natural history of non‐radiographic axial spondyloarthritis (nr‐axSpA) using KOrean Nonradiographic Axial SPondyloArthritis (KONASPA) data. Methods: Data were collected from 11 centers in South Korea. A total of 278 patients with nr‐axSpA from January 2018 to July 2020 were included. Demographic data, clinical features, comorbidities, disease activity, medications, and laboratory results were collected. Results: Mean age at symptom onset was 28.2 ± 14.2 years. Of 278 patients, 152 (54.7%) were male. Mean Bath Ankylosing Spondylitis Disease Activity Index at diagnosis was 3.5 ± 2.1. Dyslipidemia was the most common comorbidity (8.4%), followed by hypertension (6.1%). Mean age at diagnosis of nr‐axSpA was older in female patients than in male patients (31.8 ± 15.8 years vs 24.9 ± 12.0 years, P < 0.001). Enthesitis and uveitis were more frequently found in female patients than in male patients. Thirty‐one (11.1%) participants with nr‐axSpA progressed to ankylosing spondylitis. The median follow‐up duration was 48 months. In multivariable Cox regression analysis, age at symptom onset (hazard ratio [HR] 0.93, 95% confidence interval (CI) 0.88‐0.97, P = 0.006), body mass index (BMI) (HR 1.24, 95% CI 1.06‐1.44, P = 0.005) and sacroiliitis grade (HR 1.86, 95% CI 1.19‐2.92, P = 0.006) were associated with progression to ankylosing spondylitis. Conclusions: Results of nationwide data revealed that women with nr‐axSpA showed a late disease onset and more extra‐articular manifestations than men. Young age at symptom onset, high BMI, and presence of radiographic sacroiliitis at diagnosis were risk factors for progression to AS. [ABSTRACT FROM AUTHOR]

Aim: To evaluate the effect of tumor necrosis factor a inhibitors (TNFi) on spinal radiographic progression in patients with ankylosing spondylitis (AS). Methods: Subjects were selected from patients at a single tertiary hospital between 1995 and 2014. Patients who used TNFi with baseline and paired follow-up radiographic data with a minimum interval of 2 years were included. Time to start TNFi was defined as the time from symptom onset to the start of TNFi use. TNFi index was defined as the ratio of the period of TNFi use to the entire period of disease. Radiographic damage was assessed by the modified Stoke Ankylosing Spondylitis Spine Score (mSASSS). Univariable and multivariable linear regression analyses were used to identify factors associated with radiographic progression. Results: A total of 151 patients were included in the analysis. Seventeen (11.3%) patients were female and mean DmSASSS/year was 1.01 units/year. Mean X-ray follow-up duration was 102.9 ± 54.9 months. Mean time from symptom onset to start of TNFi use was 104.8 ± 83.6 months (median 84 months) and mean TNFi index was 42.9 ± 23.8% (median 40.9%). In multivariable analysis, initial mSASSS, initial C-reactive protein, body mass index, current smoker, and delayed start of TNFi use were associated with radiographic progression. Presence of peripheral arthritis and the TNFi index were negatively associated with radiographic progression. Conclusions: A delay in starting TNFi use and low TNFi index were associated with radiographic progression. Early and long-term use of TNFi appear to reduce spinal radiographic progression in patients with AS. [ABSTRACT FROM AUTHOR]

CLIMATE change , *POLLUTANTS , *FARMS , *SUSPENDED solids , *SOILS - Abstract
The soil vulnerability index (SVI) classifies vulnerability to cropland pollutant transport by surface runoff and leaching, helping to categorize areas with a high contribution of pollutant loads. This study aims to 1) adopt the SVI classification scheme in South Korea and 2) suggest a modified SVI classification scheme for surface runoff to anticipate climate change impacts. The precipitation amount was considered in an original scheme to make a modified scheme. The results with an original SVI classification scheme predicted that the SVI surface runoff vulnerability was relatively greater in areas with a steep slope than in those with a plain topography, and a high level of the SVI leaching vulnerability was frequently observed in plain areas. When a modified SVI classification scheme was applied, "High" vulnerability class increased from 44.0% to 57.4% and the greater increase rate was observed in the regions susceptible to heavy precipitation defined as a day with more than 80 mm precipitation. When compared with observational suspended solids, the results with a modified SVI classification scheme were more consistent with observations than those with an original SVI classification scheme. Relative to the baseline period, the SVI surface runoff vulnerability of "High" class increased by 47.1–88.7% during the climate change period. When the number of vulnerability classes was increased, the differences on "Very extremely high" class between the baseline and projection periods were clear with the increase rate of 16.4–343%. The results with an original SVI classification scheme matched well with the topographic characteristics, and a modified SVI classification scheme captured the impacts of regional precipitation patterns and climate change impacts. As a first approach to adopting the SVI classification system to South Korea, increasing the number of classifications in regions with excessive rainfall amounts can improve identifying those most vulnerable areas. • The SVI was developed to classify soil vulnerability classes to cropland pollutant. • The SVI classification scheme was tested on croplands across South Korea. • The SVI classification results agreed well with topographic characteristics. • An original classification scheme was modified to consider precipitation amount. • A modified classification scheme showed enhanced SVI classification results.

Objectives: This study aimed to evaluate the association of knee osteoarthritis (OA) with comorbidities and health-related quality of life (HRQOL). Methods: A total of 8,907 (weighted n = 13,687,058) participants aged ≥50 years who had undergone knee radiography were selected from the 2010–2012 Korea National Health and Nutrition Examination Survey. OA was classified into four subgroups based on the presence or absence of pain and radiographic OA (ROA): non-OA (Pain-/ROA-), pain only (Pain+/ROA-), ROA only (Pain-/ROA+), and painful ROA (Pain+/ROA+). ROA was defined as Kellgren–Lawrence grade ≥ 2. HRQOL measurements including EuroQOL visual analogue scale (EQ-VAS) scores and the five dimensions and summary index of the EuroQOL-5 dimension (EQ-5D index) were also analyzed. Multivariable logistic regression and linear regression analyses were performed. Results: After adjustment for socioeconomic and lifestyle characteristics, cardiovascular disease, malignancy, and other comorbidities were not significantly associated with OA. Pain only and painful ROA were each significantly associated with limitations in physical activity (odds ratio (OR) 2.66, 95% CI 2.07–3.44, p < 0.001 and OR 2.83, 95% CI 2.25–3.58, p < 0.001, respectively), lower EQ-VAS (β-coefficient = -10.95, p < 0.001 and β-coefficient = -9.75, p < 0.001, respectively), and EQ-5D index (β-coefficient = -0.10, p < 0.001 and β-coefficient = -0.13, p < 0.001) compared with the non-OA group, whereas ROA only was not associated with limitations in physical activity or lower HRQOL score. Conclusions: Comorbidities were not significantly associated with knee OA after adjustment. Knee OA was associated with physical activity and HRQOL. Painful knee OA, with or without ROA, was more strongly associated with decreased physical activity and lower quality of life than ROA without pain. [ABSTRACT FROM AUTHOR]

RHEUMATOID arthritis , *COMORBIDITY , *HEALTH & Nutrition Examination Survey , *DISEASE prevalence , *RETROSPECTIVE studies - Abstract
This study aimed to evaluate the prevalence of comorbidities in patients with rheumatoid arthritis (RA) compared with the non-RA population. The 2010–2012 Korea National Health and Nutrition Examination Survey (KNHANES), which assesses the general health status of populations in South Korea using interviews and basic health assessment, was analyzed retrospectively. Weighted prevalence and odds ratio (OR) of comorbidities were analyzed in patients with RA compared with the non-RA population. The overall weighted (n = 37,453,158) prevalence of RA was 1.5%. Patients with RA were older and more female predominant than subjects without RA. The prevalence of living in an urban area, college graduation, alcohol consumption and smoking was lower in patients with RA than non-RA. Patients with RA had more comorbidities including hypertension, dyslipidemia, myocardial infarction (MI) or angina, stoke, osteoarthritis, lung cancer, colon cancer, pulmonary tuberculosis, asthma, diabetes, depression, thyroid disease and chronic kidney disease. After adjusting socioeconomic and lifestyle characteristics, RA was associated with an increased prevalence of MI or angina (OR 1.86, 95% CI 1.17–2.96, p = 0.009), pulmonary TB (OR 1.95, 95% CI 1.24–3.09, p = 0.004), asthma (OR 1.97, 95% CI 1.05–3.71, p = 0.036), thyroid disease (OR 1.71, 95% CI 1.05–2.77), depression (OR 2.38, 95% CI 1.47–3.85, p < 0.001) and hepatitis B (OR 2.34, 95% CI 1.15–4.80, p = 0.020) compared with the non-RA population. Prevalence of solid cancer was not significantly associated with RA after adjustment. [ABSTRACT FROM AUTHOR]

This study aimed to evaluate the association between rheumatoid arthritis (RA) and hearing impairment in the Korean adult population. Audiometric and laboratory test data from the 2010–2012 Korean National Health and Nutrition Examination Survey (KNHANES) were used for analysis. The relationship between RA and hearing impairment was analyzed, adjusting for various known risk factors associated with hearing impairment. RA was defined in the questionnaire as “RA diagnosed by a physician (yes/no) through a standardized interview.” We defined hearing impairment according to 2 categories of frequency (low/mid and high) as follows (average values in kHz): low/mid frequency, 0.5, 1.0, and 2.0, and high frequency, 3.0, 4.0, and 6.0. Of the subjects, 15,158 (weighted n = 32,035,996) completed the audiometric tests. The overall weighted prevalence of RA was 1.5%. The prevalence of hearing impairment was higher in the subjects with RA than in those without RA, in both, the low/mid- and high-frequency categories (21.1% vs 7.5%, p < 0.001 and 43.3% vs. 26.2%, p < 0.001, respectively). In the multivariable logistic analysis, RA (odds ratios [OR] 1.47, 95% confidence interval [CI] 1.05–2.06, p = 0.025) was an independent risk factor of low/mid-frequency hearing impairment along with age (OR 1.12, 95% CI 1.12–1.13, p < 0.001), current smoking (OR 1.27, 95% CI 1.03–1.56, p = 0.026), and college graduation (OR 0.53, 95% CI 0.39–0.72, p < 0.001). In the multivariable analysis of high-frequency hearing impairment, RA did not show any association with hearing impairment. This study suggests that RA is associated with low/mid-frequency hearing impairment after adjustment for various known risk factors. Further study is needed to verify the hearing impairment in RA.

- Abstract
Abstract: Colchicine is a relatively safe medication that is widely used for both prevention and treatment of gout attack. However, serious adverse events, including myoneuropathy and multiorgan failure, have been reported. We report a case of colchicine-induced myoneuropathy in a female kidney transplant recipient who had been taking cyclosporine. She developed gastrointestinal discomfort and paresthesia 5 days after the initiation of colchicine. She showed signs of myoneuropathy, and hepatic and renal injury. Colchicine toxicity was suspected, and colchicine was discontinued. Her symptoms and laboratory findings improved gradually. Literature was reviewed for previous reports of colchicine-induced myoneuropathy in solid organ transplant recipients. [Copyright &y& Elsevier]

Abstract: A 48-year-old man presented with acute right flank pain. A computed tomography scan revealed right renal infarction. Because he had no thrombosis in the renal vessels and no clear embolic source, a further examination was performed to find the cause of the renal infarction. On transesophageal echocardiography, a right-to-left shunt during the Valsalva maneuver established a diagnosis of patent foramen ovale. This is a case of paradoxical embolism through a PFO leading to renal infarction. [Copyright &y& Elsevier]

- Abstract
Purpose: To investigate urine microbiome differences among healthy women, women with recurrent uncomplicated cystitis (rUC), and those with sporadic/single uncomplicated cystitis (sUC) to challenge traditional beliefs about origins of these infections., Materials and Methods: Patients who underwent both conventional urine culture and next-generation sequencing (NGS) of urine were retrospectively reviewed. Symptom-free women with normal urinalysis results as a control group were also studied. Samples were collected via transurethral catheterization., Results: In the control group, urine microbiome was detected on NGS in 83.3%, with Lactobacillus and Prevotella being the most abundant genera. The sensitivity of urine NGS was significantly higher than that of conventional urine culture in both the sUC group (91.2% vs. 32.4%) and the rUC group (82.4% vs. 16.4%). In urine NGS results, Enterobacterales , Prevotella , and Escherichia / Shigella were additionally found in the sUC group, while the recurrent urinary tract infection (rUTI)/rUC group exhibited the presence of Lactobacillus , Prevotella , Enterobacterales , Escherichia / Shigella , and Propionibacterium . Moreover, distinct patterns of urine NGS were observed based on menopausal status and ingestion of antibiotics or probiotics prior to NGS test sampling., Conclusions: Urine microbiomes in control, sUC, and rUTI/rUC groups exhibited distinct characteristics. Notably, sUC and rUC might represent entirely separate pathological processes, given their distinct urine microbiomes. Consequently, the use of urine NGS might be essential to enhancing sensitivity compared to conventional urine culture in both sUC and rUTI/rUC groups., Competing Interests: The authors have nothing to disclose., (© The Korean Urological Association.)

- Abstract
Background and Objectives : Hyperuricemia is associated with several comorbidities. The association between uric acid (UA) and pulmonary function is still a controversial issue. This study evaluated the gender-specific association of serum UA and pulmonary function. Materials and Methods : A total of 3177 (weighted n = 19,770,902) participants aged 40 years or older were selected from the 2016 Korean National Health and Nutrition Examination Survey and included. Results : Female participants with hyperuricemia were older than participants with normouricemia. Body mass index (BMI), mean arterial pressure (MAP), hemoglobin A1c (HbA1c), and estimated glomerular filtration rate (eGFR) were significantly associated with UA levels in both males and females. Hyperuricemia and increase in UA quartile were significantly associated with decreased forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) in females after adjustment for age, income, region, education, marital status, alcohol consumption, smoking, BMI, MAP, HbA1c, and eGFR. There was no significant association between UA levels and lung function in males. After additional adjustment for respiratory disease including pulmonary tuberculosis, asthma, and lung cancer, the association between hyperuricemia and decreased FEV1 and FVC in females was revealed. Conclusions : Hyperuricemia was associated with decreased FVE1 and FVC in the female general population.

- Abstract
Objective: Ankylosing spondylitis (AS) is a chronic inflammatory disease with obvious male preponderance Males show more severe radiographic manifestations compared with females This study aimed to evaluate the effects of sex and estrogen on the radiographic progression of AS., Methods: A total of 101 patients with AS were included in this study All of the radiographs were scored using the modified Stoke AS Spine Score (mSASSS) Serum levels of 17β-estradiol (E2), dickkopf-1 (Dkk1), and leptin were detected by enzyme-linked immunosorbent assay The generalized estimating equations model was used to evaluate factors associated with spinal radiographic progression., Results: The mean age at disease onset was 273±107 years, and 16 patients (158%) were female In the multivariable analysis, body mass index (β-coefficient=012; p=0047) and levels of Dkk1 (β-coefficient=-011; p<0001), and female (β-coefficient=-140; p=0001) were associated with radiographic progression Among male patients with AS, baseline C-reactive protein (β=011; p=0005) and mSASSS (β=021; p=0030) were also associated with radiographic progression E2 and leptin levels were not significantly related to the radiographic progression., Conclusion: Although female patients were associated with less radiographic progression in AS, there was no significant relationship between serum estrogen level and radiographic progression Results of current study suggests that genetic factors or other environmental factors associated with female may influence radiographic progression in patients with AS., Competing Interests: CONFLICT OF INTEREST No potential conflict of interest relevant to this article was reported., (Copyright © 2021 by The Korean College of Rheumatology.

- Abstract
Objective: Plasma C reactive protein (CRP) is a marker of inflammation, and increased plasma CRP is reported in many diseases, including cardiovascular disease, diabetes, metabolic syndrome, arthritis and malignancies. The aim of the study was to evaluate the association between plasma CRP levels and cardiovascular disease, metabolic syndrome, malignancies and other comorbidities., Design: A retrospective, cross-sectional survey study., Setting: Large population survey in Korea., Methods: A total of 5887 (weighted n=40 251 868) participants aged 19 years or older from the 2016 Korea National Health and Nutrition Examination Survey were included for analysis. Weighted prevalence and OR of comorbidities were analysed according to the continuous variable of log plasma high-sensitivity CRP levels., Results: The mean age was 46.7±0.37 years and the median plasma CRP was 0.58 mg/L (IQR 0.36-1.09). The mean plasma CRP levels were higher in participants with cardiovascular diseases and cardiovascular risk factors, osteoarthritis, rheumatoid arthritis, pulmonary tuberculosis, and several cancers, including gastric, colon, breast and cervix, than in the general population. In the multivariable analysis, plasma CRP concentration was associated with increased prevalence of hypertriglyceridaemia (OR 1.157, 95% CI 1.040 to 1.287, p=0.007), diabetes (OR 1.204, 95% CI 1.058 to 1.371, p=0.005) and metabolic syndrome (OR 1.228, 95% CI 1.112 to 1.357, p<0.001) after adjustment for socioeconomic and lifestyle characteristics. There was no significant association between plasma CRP level and cancers., Conclusion: Plasma CRP was associated with an increased risk of dyslipidaemia, diabetes and metabolic syndrome in the general population., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2019.

- Abstract
Background: Rheumatoid arthritis (RA) treatment may differ according to hepatitis B state and consequently may bring about different arthritis outcomes. However, whether hepatitis B affects treatment outcome remains unclear. We investigated differences in change in arthritis activity between RA patients according to concomitant hepatitis B virus infection., Methods: A retrospective medical chart review was performed by two rheumatologic fellows using single center data, from January 2000 to March 2015. Among RA patients older than 18 years, patients with comorbidities that could affect RA treatment aside from hepatitis B were excluded. Using 1:3 propensity score matching, 40 hepatitis B virus surface antigen (HBsAg)-positive patients and 112 HBsAg-negative patients were included in the study. Data were collected longitudinally using standardized electronic forms. The longitudinal relationship between HBsAg-positivity and RA activity was analyzed using generalized estimating equations., Results: RA activity showed time-dependent improvement. Reductions of swollen joint count over time were significantly larger in the HBsAg-negative group. However, changes in disease activity score in 28 joints with three variables (DAS28-3), tender joint count, erythrocyte sedimentation rate and C-reactive protein level did not differ between the groups. There were no differences in alanine aminotransferase level. HBsAg-positive patients were less likely to receive methotrexate (odds ratio [OR], 0.09; 95% confidence interval [CI], 0.04-0.19; P < 0.001) and more likely to receive sulfasalazine (OR, 3.67; 95% CI, 1.94-6.95; P < 0.001)., Conclusion: RA medication use varied according to HBsAg-positivity. However, improvement in RA activity was not significantly affected by concomitant hepatitis B infection., Competing Interests: Disclosure: The authors have no potential conflicts of interest to disclose.

- Abstract
Background/aims: To evaluate drug survival of the tumor necrosis factor α inhibitors (TNFi) and risk factors for the drug discontinuation in patients with ankylosing spondylitis (AS)., Methods: We retrospectively evaluated 487 AS patients at a single tertiary hospital. Among the TNFi users, drug survival and risk factors of TNFi discontinuation were investigated., Results: Among 487 patients, 128 AS patients were treated with at least one TNFi. Patients who were treated with TNFi were younger at disease onset, had more peripheral manifestations, and had higher level of acute phase reactants and body mass index than those of TNFi non-users at baseline. Of 128 patients, 28 patients (21.9%) discontinued first TNFi therapy during the follow-up period of 65.1 ± 27.9 months. In the multivariable analysis, female (hazard ratio [HR], 6.08; 95% confidence interval [CI], 2.27 to 16.27; p = 0.003), hip involvement (HR, 2.52; 95% CI, 1.08 to 5.87; p = 0.033) and a high C-reactive protein (CRP; HR, 1.10; 95% CI, 1.00 to 1.21; p = 0.044) were risk factors for drug discontinuation. Etanercept showed better survival rate than infliximab. The main reason for discontinuation of TNFi was inefficacy., Conclusions: TNFi discontinuation rate of Korean patients with AS seems to be similar to those with the European patients. Female sex, hip involvement, CRP, and the type of TNFi were associated with TNFi discontinuation.

- Abstract
Prognosis has not been known for patients with fever of unknown origin (FUO) whose ¹⁸fluoro-deoxyglucose (¹⁸F-FDG) positron emission tomography/computerized tomography (PET/CT) finding is non-diagnostic. A total of eight patients with FUO that underwent ¹⁸F-FDG PET/CT were retrospectively identified January 2016 - June 2017 in a tertiary hospital in Korea. Of these, two patients were diagnosed with microscopic polyangitis and Kikuchi's disease and one patient was transferred to another hospital. Of five patients whose diagnoses were not confirmed, four patients received non-steroidal anti-inflammatory drug and/or low dose steroid and symptoms disappeared. Our study suggests that outcome of patients with FUO whose ¹⁸F-FDG PET/CT finding is non-diagnostic would be favorable., Competing Interests: No conflicts of interest., (Copyright © 2018 by The Korean Society of Infectious Diseases and Korean Society for Chemotherapy.)

- Abstract
Background: Ankylosing spondylitis (AS) is a male-predominant disease, and radiographic evidence of damage is also more severe in males. Estrogen modulates immune-related processes such as T cell differentiation and cytokine production. This study aimed to evaluate the effect of estrogen on the disease activity of spondyloarthritis (SpA)., Methods: The effects of estrogen on the development of arthritis were evaluated by performing ovariectomy and 17β-estradiol (E2) pellet implantation in zymosan-treated SKG mice. Clinical arthritis scores were measured, and
18 F-fluorodeoxyglucose (18 F-FDG) small-animal positron emission tomography/computed tomography performed to quantify joint inflammation. The expression of inflammatory cytokines in joint tissue was measured., Results: E2-treated mice showed remarkable suppression of arthritis clinically and little infiltration of inflammatory cells in the Achilles tendon and intervertebral disc.18 F-FDG uptake was significantly lower in E2-treated mice than in sham-operated (sham) and ovariectomized mice. Expression of TNF, interferon-γ, and IL-17A was significantly reduced in E2-treated mice, whereas expression of sclerostin and Dickkopf-1 was increased in E2-treated mice compared with sham and ovariectomized mice., Conclusions: Estrogen suppressed arthritis development in SKG mice, a model of SpA. Results of this study suggest that estrogen has an anti-inflammatory effect on the spondyloarthritis manifestations of the SKG arthritis model.- Published

- Abstract
Background/aims: To evaluate the clinical course of hip arthritis and the risk factors for hip joint replacement in patients with ankylosing spondylitis (AS)., Methods: In this retrospective analysis, we evaluated 488 AS patients at a single tertiary hospital. At baseline and the most recent visit to the outpatient clinic from the patients with hip arthritis in AS, radiographic hip arthritis was evaluated using the Bath Ankylosing Spondylitis Radiology Hip Index (BASRI-h). Also the average of the hip joint space width (interbone distance) at three distinct sites between the acetabulum and femoral head was recorded., Results: Among 488 patients with AS, 60 patients (12.3%) had hip arthritis. Erythrocyte sedimentation rate were associated with hip involvement (odds ratio, 1.01; 95% confidence interval [CI], 1.00 to 1.02; p = 0.004). Long disease duration and advanced axial disease were associated with severe hip arthritis (3 ≥ BASRI-h) at baseline. BASRI-h and interbone distance did not significantly change in patients with hip involvement during the follow-up period of 81.4 ± 35.7 months. Five patients had hip joint replacement surgery during follow-up period. The body mass index (BMI) and BASRI-h at baseline were associated with joint replacement surgery (hazard ratio [HR], 1.30; 95% CI, 1.00 to 1.67; p = 0.049 and HR, 20.64; 95% CI, 2.39 to 178.11; p = 0.006, respectively)., Conclusions: Most of the patients with hip arthritis in AS showed no significant radiographic progression during the follow-up period. High BMI and advanced hip arthritis at baseline were associated with hip joint replacement surgery in patients with AS., Competing Interests: No potential conflict of interest relevant to this article was reported.

- Abstract
Objective: The development of anti-drug antibodies (ADAbs) against tumor necrosis factor (TNF) inhibitors is a likely explanation for the failure of TNF-inhibitors in patients with spondyloarthritis (SpA). Our study determined the existence and clinical implications of ADAbs in axial SpA patients., Methods: According to the Assessment of SpondyloArthritis International Society classification criteria for axial SpA, patients treated with adalimumab or infliximab were recruited consecutively. Serum samples were collected at enrollment to measure ADAb and drug levels., Results: Of 100 patients, the mean duration of current TNF inhibitor use was 22.3±17.9 months. ADAbs were detected in 5 of 72 adalimumab users compared to 5 of 28 infliximab users (6.9% vs. 17.9%). ADAb-positive patients had a significantly higher body mass index than ADAb-negative patients among both adalimumab (28.4±5.9kg/m
2 vs. 24.3±2.9kg/m2 , respectively, p=0.01) and infliximab users (25.9±2.8kg/m2 vs. 22.6±2.8kg/m2 , respectively, p=0.02). During the median 15-month follow-up period, drug discontinuation occurred more frequently in the ADAb-positive group than the ADAb-negative group (30.0% vs. 6.5%, respectively, p=0.04). In logistic regression, ADAb positivity (OR=5.85, 95% CI 1.19-28.61, p=0.029) and BMI (OR=4.35, 95% CI 1.01-18.69, p=0.048) were associated with a greater risk of stopping TNF inhibitor treatment., Conclusions: Our result suggests that the presence of ADAbs against adalimumab and infliximab as well as a higher BMI can predict subsequent drug discontinuation in axial SpA patients., (Copyright © 2016.

- Abstract
Background/aims: The course of ankylosing spondylitis (AS) is rather variable, and the factors that predict radiographic progression remain largely obscure. In this study, we tried to determine the clinical factors and laboratory measures that are useful in predicting the radiographic progression of patients with AS., Methods: In 64 consecutive patients with AS, we collected radiographic and laboratory data over 3 years. Radiographic data included images of the sacroiliac (SI) and hip joints and laboratory data included areas under the curve (AUC) of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), alkaline phosphatase (ALP), and hemoglobin (Hb). We investigated associations among changes in radiographic scores, initial clinical manifestations and laboratory measurements., Results: Changes in scores for the SI joint and lumbar spine did not correlate with AUC for ESR, CRP, or ALP. AUC for Hb did not significantly correlate with radiographic progression in any joint. Patients with hip arthritis at the initial visit showed significantly higher radiographic score changes after 3 years in the SI and hip joint compared to those without hip arthritis. Patients who had shoulder arthritis as the initial manifestation had significantly increased AUCs for ESR and CRP compared to those without shoulder arthritis. However, at 3 years, the change of the lumbar spine score was significantly higher in patients without shoulder arthritis., Conclusions: These results indicate that hip arthritis at presentation is a useful clinical marker for predicting the structural damage to the SI and hip joint, and suggest that initial shoulder arthritis correlates with slower radiographic progression of the lumbar spine.

- Abstract
A 71-year-old male patient was readmitted to our hospital 1 month after discharge because of relapse of abdominal pain. He had been diagnosed with hepatocellular carcinoma (HCC) 1 year prior and had undergone repeated transcatheter arterial chemoembolization and radiotherapy. During the last hospitalization, he was diagnosed with a liver abscess complicated by previous treatments for HCC and was treated with intravenous antibiotics and abscess aspiration. Follow-up abdominal computed tomography revealed a liver abscess with a duodenal fistula, which was successfully treated with endoscopic Histoacryl injection into the fistula. Liver abscesses with duodenal fistulas rarely occur, but they are intractable and possibly fatal in patients with HCC. In the literature, they have frequently been managed only with abscess treatment without fistula management. We herein report the first case of a patient with a liver abscess complicated by a fistula between the duodenum and the abscess, which was treated with endoscopic Histoacryl injection.

- Abstract
Both Graves disease and Guillain-Barre syndrome (GBS) are autoimmune disorders caused by impaired self-tolerance mechanisms and triggered by interactions between genetic and environmental factors. GBS in patients who suffer from other autoimmune diseases is rarely reported, and the development of postinfectious GBS in a patient with Graves disease has not been previously reported in the literature. Herein, we report a patient with Graves disease who developed postinfectious GBS during a course of methimazole-induced agranulocytosis.

- Abstract
Background/aims: We investigated the clinical characteristics and follow-up findings of subjects with adrenal incidentalomas in a single, tertiary-care hospital in South Korea., Methods: The study consisted of a retrospective analysis of 282 adrenal incidentaloma patients who underwent radiographic and endocrinological evaluations at Samsung Medical Center in Seoul, South Korea, between January 2004 and July 2011., Results: Most (86.2%) of the subjects were found to have nonfunctioning tumors. Functioning tumors were seen in 39 patients (13.8%). Among them, 28 (9.9%) had subclinical Cushing syndrome (SCS), six (2.1%) had pheochromocytoma, and five (1.8%) had primary hyperaldosteronism. Malignant adrenal tumors were discovered in three cases: two (0.7%) were primary adrenal cancers, and one (0.4%) was a secondary metastasis from a lung cancer. Significant risk factors for functional tumors were female gender (odds ratio [OR], 3.386; 95% confidence interval [CI], 1.611 to 7.117; p = 0.0013) and a noncontrast attenuation value of > 10 Hounsfield units (OR, 2.806; 95% CI, 1.231 to 6.397; p = 0.0141). During follow-up (mean, 22.5 months) of 72 of the patients, three (4.2%) developed hormonal changes due to functional tumors. One was confirmed as pheochromocytoma by histopathology, and the others were diagnosed with SCS and followed routinely without surgical intervention. No malignant transformation was found in these patients., Conclusions: Based on these findings, initial hormonal and radiographic evaluations for adrenal incidentalomas appear to be more important than follow-up tests because functional or malignant changes are rare.

- Abstract
The incidence of pulmonary embolism (PE) rises markedly with age, and only a few cases have been reported in younger adults. Thrombophilia has been reported as one of the predisposing factors for PE in younger adults. Here we report an extraordinary case of PE complicated with dysplasminogenemia, a rare genetic disorder resulting in hypercoagulability, in a young male. An 18-yr-old male visited an emergency room in the United States complaining chest discomfort. He was diagnosed as PE with deep vein thrombosis without apparent risk factors. Anticoagulation therapy with warfarin had been initiated and discontinued after 6 months of treatment. After returning to Korea he was tested for thrombophilia which revealed decreased activity of plasminogen and subsequent analysis of PLG gene showed heterozygous Ala620Thr mutation. He was diagnosed with PE complicated with dysplasminogenemia. Life-long anticoagulation therapy was initiated. He is currently under follow-up without clinical events for 2 yr.

- Abstract
We report the case of a 36-year-old woman who presented with headache, fever, and amenorrhea. Laboratory analysis revealed hypopituitarism and autoimmune thyroiditis, while a cerebrospinal fluid study suggested concurrent aseptic meningitis. A magnetic resonance image (MRI) scan revealed a 1.0×0.9 cm cystic mass enlarging the sella turcica. Surgical resection via an endoscopic transsphenoidal route was performed. The histological finding of the excised tissue revealed foamy histiocytes with vacuolated cytoplasm, supporting the diagnosis of xanthomatous hypophysitis. Although a residual soft lesion was observed on the MRI image postoperatively, the patient's headache and fever improved. Ten months after surgery, the patient complained of visual impairment and headache, and the residual mass had enlarged into the suprasellar area.
