Objective. The objective of this study was to investigate the impact of disease onset age on mortality and renal survival in female SLE patients.Methods. This nationwide, population-based, retrospective cohort study used data from the National Health Insurance Research Database of Taiwan. Female patients newly diagnosed with SLE from 2001 to 2004 were identified as the study cohort. A non-SLE group was matched for age, sex and initial diagnosis date (index date) as the comparison cohort. Co-morbidities, mortality rates and end-stage renal disease (ESRD) incidences were compared among SLE patients of different onset age. Hazard ratios with a 95% CI were determined by the Cox proportional hazard model to quantify the mortality rates and ESRD incidences. Juvenile-onset, adult-onset and late-onset SLE patients were categorized according to disease onset age: <18, 18–50 and >50 years old.Results. In total, 513 juvenile-onset, 3076 adult-onset and 764 late-onset SLE patients were identified. Compared with non-SLE controls, the hazard ratios of mortality were 6.49 (95% CI 3.73, 11.32, P < 0.001) for juvenile-onset, 1.75 (95% CI 1.47, 2.08, P < 0.001) for adult-onset and 3.44 (95% CI 2.76, 4.28, P < 0.001) for late-onset SLE patients. The hazard ratios of incident ESRD were 20.28 (95% CI 12.79, 32.15, P < 0.001) for adult-onset lupus patients and 1.99 (95% CI 1.36, 2.93, P < 0.001) for late-onset patients.Conclusion. Female patients with late-onset SLE carried a higher risk of mortality than those with adult-onset disease in the presence of co-morbidities. Juvenile-onset SLE patients were at greatest risk of mortality, which is probably due to disease severity. [ABSTRACT FROM PUBLISHER]

Background/purpose: Adalimumab is a fully humanized monoclonal antibody that blocks tumor necrosis factor (TNF)-alpha, which is effective in the treatment of patients with rheumatoid arthritis (RA). The purpose of this study was to compare the efficacy and safety of adalimumab plus methotrexate (MTX) and MTX alone in Taiwanese patients with active RA.Methods: Forty-seven patients with active RA who were maintained on MTX therapy at a stable dose of 10-15 mg/week for 4 weeks were randomized blindly to receive adalimumab 40 mg (n = 35) or placebo (n = 12) by subcutaneous injection every other week over a period of 12 weeks. The primary endpoint was a reduction in tender and swollen joint counts of 20% (ACR20), 50% (ACR50) and 70% (ACR70), as determined by the American College of Rheumatology criteria in week 12. The occurrence of treatment-emergent adverse events (TEAEs) was the primary safety variable.Results: Addition of adalimumab to MTX resulted in a significant reduction in the number of swollen joints (12.6 vs. 5.6; p = 0.011), patients' global assessment of disease activity (18.0 vs. 4.8; p = 0.040), pain visual analog scale (18.3 vs. 1.3; p = 0.015), and disability indices of the Health Assessment Questionnaire (0.6 vs. 0.2; p = 0.031), compared with MTX alone after 12 weeks of therapy. Overall improvement in disease activity was assessed by ACR20 (54.3% vs. 33.3%), ACR50 (34.3% vs. 16.7%) and ACR70 (14.3% vs. 0%), and all favored the adalimumab plus MTX group. TEAEs were comparable between the treatment groups, except for a slightly higher incidence of severe infection in the adalimumab plus MTX group.Conclusion: Adalimumab in combination with MTX is well tolerated and provides significantly more clinical benefits than MTX alone in Taiwanese patients with active RA.

In this study we aimed to identify the predictors of drug survival for biologic and targeted synthetic DMARDs (bDMARDs and tsDMARDs) among patients with rheumatoid arthritis (RA) in a real-world setting. Data from RA patients receiving bDMARDs and tsDMARDs between 2007 and 2019 were extracted from the Taiwan Rheumatology Association Clinical Electronic Registry (TRACER). Patients were categorized into tumor necrosis factor-alpha (TNF-α) inhibitors, non-TNF-α inhibitors, and tofacitinib groups. The primary outcome was 3-year drug retention and the causes of bDMARDs and tsDMARDs discontinuation were recorded. Baseline demographic data before the initiation of bDMARDs and tsDMARDs treatment were analyzed to identify the predictors of 3-year drug survival. A total of 1,270 RA patients were recruited (TNF-α inhibitors: 584; non-TNF-α inhibitors: 535; tofacitinib: 151). The independent protective factors for 3-year drug survival were positive rheumatoid factor (RF) (HR: 0.48, 95% CI: 0.27-0.85, p = 0.013) and biologics-naïve RA (HR: 0.61, 95% CI: 0.39-0.94, p = 0.024). In contrast, positive anti-citrullinated protein antibody (ACPA) (HR: 2.24, 95% CI: 1.32-3.79, p = 0.003) and pre-existing latent tuberculosis (HR: 2.90, 95% CI: 2.06-4.09, p<0.001) were associated with drug discontinuation. RA patients treated with TNF-α inhibitors exhibited better drug retention, especially in the biologics-naïve subgroup (p = 0.037). TNF-α inhibitors were associated with lower cumulative incidence of discontinuation due to inefficacy and adverse events (both p<0.001). Baseline RF and ACPA positivity in abatacept-treated patients were associated with a better 3-year drug survival. However, negative ACPA levels predicted superior drug survival of TNF-α inhibitors and tofacitinib. In conclusion, bio-naïve status predicted better drug survival in TNF-α inhibitors-treated RA patients. RF and ACPA positivity predicted better abatacept drug survival. In contrast, ACPA negativity was associated with superior TNF-α inhibitors and tofacitinib survival., Competing Interests: The authors have declared that no competing interests exist.

Objective: To assess the associations of the Assessment of Spondyloarthritis International Society Health Index (ASAS HI) with gender and other factors in patients with ankylosing spondylitis (AS)., Methods: From November 2017 to October 2018, we measured the Ankylosing Spondylitis Disease Activity Score (ASDAS), the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), the Bath Ankylosing Spondylitis Functional Index (BASFI), the modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS) and the ASAS HI score for AS patients at the Taichung Veterans General Hospital. After adjusting for disease activity (ASDAS-erythrocyte sedimentation rate [ESR], ASDAS- C-reactive protein [CRP], BASDAI+ESR or BASDAI+CRP), mSASSS and other potential confounders including medications, comorbidities, and laboratory data, any associations between gender and the sum score of ASDAS HI were assessed using multiple linear regression analysis, as well as any associations between gender and an ASAS HI score >5 using multivariable logistic regression analysis., Results: A total of 307 AS patients (62 [20.2%] females, mean age 46.4 years [S.D. 13.3], mean symptom duration 20.6 years [S.D. 12.1]) were included. Multiple linear regression analysis showed that the male gender was significantly associated with a lower ASAS HI (B = -1. 91, 95% confidence interval [CI], -2.82--1.00, p <0.001). Multivariable logistic regression analysis revealed that males also had a lower risk of achieving scores of ASAS HI > 5 than females (odds ratio = 0.15, 95% CI, 0.07-0.36, p <0.001). Disease activity measures, including ASDAS-ESR, ASDAS-CRP and BASDAI, had positive correlations with ASAS HI., Conclusion: This single-center, cross-sectional study revealed that a higher ASAS HI score was significantly associated with female gender and higher disease activity measures., Competing Interests: The authors have declared that no competing interests exist.

Objective: To evaluate the long-term safety and effectiveness of tocilizumab (TCZ) for the treatment of rheumatoid arthritis (RA) in a real-world clinical setting in Taiwan., Method: All refractory RA patients who initiated intravenous TCZ between August 2012 and March 2015 were enrolled. Data on patient characteristics, drug safety and effectiveness were collected., Results: A total of 114 RA patients were recruited. Despite the majority of them (93%) had previous biologic failure, 43.75% of the patients were able to reach ACR50 after one year. Serious adverse events commonly found were bacterial pneumonia (4.24/100 patient-years) followed by cellulitis (2.12/100 patient-years). Twenty-three patients had old or latent TB infections, 11 patients had chronic hepatitis B. During the 3 years follow-up, none of them had reactivation of TB, or hepatitis B with concomitant use of isoniazid prophylaxis or pre-emptive antiviral treatment., Conclusion: In this 3-year real-world study on RA patients of Taiwan, we found a good long-term effectiveness and similar safety profiles for the TCZ treatment. With prophylactic strategy for latent TB and pre-emptive antiviral treatment for HBV carriers, the risk of reactivation of latent TB and HBV may be reassured., (Copyright © 2017.

Background: Sarcoidosis is still considered a rare multisystem disorder in Taiwan, and data on the disease course and outcome are limited. We analyzed the clinical manifestations, disease course and complications in Taiwanese patients with sarcoidosis., Methods: A retrospective cohort design was used. Fifty-six patients with sarcoidosis diagnosed between 1985 and 2004 were included. Their clinical features, laboratory findings at initial presentation, disease course, and complications were analyzed., Results: Forty-three patients (76.8%) were female. The mean age at symptom onset was 47 years. The most common clinical symptoms were pulmonary (82.1%), cutaneous (23.2%), ophthalmic (19.6%), and articular (17.8%). Only two patients presented with Löfgren's syndrome. There was a seasonal variation in disease onset, with higher incidence in winter and early spring. No advanced pulmonary involvement was noted. Elevated levels of serum angiotensin converting enzyme (sACE) were found in 72.5% (29/40) of patients with active sarcoidosis, and significantly higher levels of sACE were found in patients with lung involvement (27.98+/-1.71 IU/L vs. 18.2+/-2.76 IU/L; p<0.01). In 50% (20/40) of patients, sACE levels declined significantly in parallel with clinical remission (24.75+/-1.53 IU/L vs. 16.33+/-1.21 IU/L; p<0.05). Spontaneous complete remission was found in 20.7% of patients, whereas 39.6% of patients with multiple extrapulmonary involvement responded poorly to intensive corticosteroids plus various immunosuppressants., Conclusion: In this series, the mean age of disease onset was in middle age (mean, 47 years old), there was a low incidence of Löfgren's syndrome (3.6%), and no patients had advanced pulmonary syndrome. The results of this study also suggest that sACE might be a marker of pulmonary involvement that is also useful in monitoring disease activity.
