Trends in work participation among patients with inflammatory rheumatic musculoskeletal diseases (iRMDs): Data from the German National Database (2010-2022).

Abstract (Expand)

OBJECTIVE: To analyse work participation among patients with inflammatory rheumatic musculoskeletal diseases (iRMDs), namely rheumatoid arthritis (RA), axial spondyloarthritis (axSpA), psoriatic arthritis … (PsA), systemic lupus erythematosus (SLE), systemic sclerosis (SSc) and ANCA-associated vasculitis (AAV). METHODS: A cross-sectional sample of 16 421 patients from the National Database of the German Collaborative Arthritis Centers, aged <65 years were analysed. For each diagnosis, yearly rates of absenteeism, employment and disability pensions were analysed from 2010 to 2022. Population data were used to calculate standardised employment ratios (SERs), adjusted for age, sex, federal state and vocational qualification. The analysis was additionally stratified by sex, adjusting for other factors. RESULTS: Over the observed time span, large employment increases were found across all diagnoses, namely in RA (54%-68%), PsA (58%-72%), SSc (47%-66%), AAV (43%-61%), SLE (48%-60%) and axSpA (65%-73%). SERs were for RA 0.88 (95% CI 0.86 to 0.90), axSpA (0.88 (0.84 to 0.91)), PsA (0.88 (0.85 to 0.91)), SSc (0.83 (0.75 to 0.91)), SLE (0.76 (0.72 to 0.80)) and AAV (0.73 (0.63 to 0.83)). In RA, axSpA, PsA and AAV, SERs were higher in men while in SLE and SSc men had lower SER. Median of yearly absenteeism due to the disease decreased by 5 (RA), 1 (axSpA), 6 (PsA), 11 (SLE), 4 (SSc) and 10 days (AAV) in the time span. Except for SSc, the proportion of disability pension receivers decreased for all diagnoses. CONCLUSION: Since 2010, work participation has improved for patients with iRMDs, as reflected in higher employment, reduced absenteeism and less disability retirement. However, patients have not reached population employment rates.

Incidence of Major Adverse Cardiovascular Events in Patients With Rheumatoid Arthritis Treated With JAK Inhibitors Compared With Biologic Disease-Modifying Antirheumatic Drugs: Data From an International Collaboration of Registries

Abstract (Expand)

OBJECTIVE: Our objective was to assess the incidence of major adverse cardiovascular events (MACEs) in patients with rheumatoid arthritis (RA) treated with JAK inhibitors (JAKi), tumor necrosis factor … inhibitors (TNFi), or biologic disease-modifying antirheumatic drugs with other modes of action (bDMARD-OMA) in a multicountry, real-world population. METHODS: Patients with RA from 15 registries in the JAK-pot collaboration were included. MACE incidence was analyzed using two approaches: a within-registry analysis aggregating country-specific estimates from registers with >25 incident MACEs through meta-analysis and an individual-level data combined analysis. We used adjusted linear mixed Poisson regression to obtain incidence rate ratios (IRRs) of MACEs between treatment groups, accounting for multiple treatment courses. RESULTS: The study included 73,008 treatment courses (16,417 JAKi, 35,373 TNFi, and 21,218 bDMARD-OMA) and 828 incident MACEs among 51,233 patients. Median follow-up time was 1.3 years, with most of the follow-up concentrated in the first two years of treatment. Incidence rates were 7.0, 7.6, and 11.8 per 1,000 person-years for JAKi, TNFi, and bDMARD-OMA, respectively. Compared to TNFi, JAKi (within-registry adjusted IRR 0.89, 95% confidence interval [CI] 0.63-1.25) had similar incidence rates of MACEs and bDMARD-OMA had higher rates (within-registry adjusted IRR 1.35, 95% CI 1.10-1.66). Combined analysis showed similar results. CONCLUSION: Observational data from the JAK-pot collaboration show no evidence of an increase in cardiovascular events during the first two years of use with JAKi compared to TNFi in the general RA population.

Comparative risk of incident malignancies in rheumatoid arthritis patients treated with Janus kinase inhibitors or bDMARDs: observational data from the German RABBIT register

Abstract (Expand)

ABSTRACT Objectives To estimate the effects of Janus kinase inhibitors (JAKis) vs biologic disease-modifying antirheumatic drugs (bDMARDs) on the risk of incident malignancies (excluding nonmelanoma … skin cancer) in patients and patient subgroups with rheumatoid arthritis. Methods Episodes of disease-modifying antirheumatic drug (DMARD) treatment initiated between January 2017 and December 2020 and followed up to June 2024 in RABBIT, the German register for the long-term observation of therapy with biologics and targeted disease-modifying antirheumatic drugs in adult patients with rheumatoid arthritis, were analysed. Incidence rates (IRs) per 1000 patient-years with 95% CIs were calculated, and incident malignancy risk was estimated as hazard ratios (HRs) by inverse probability weighted adjusted Cox models. Results Among 2285 JAKi and 4259 bDMARD treatment episodes, 88 and 135 malignancies occurred, respectively. JAKi treatments were dominated by baricitinib and tofacitinib, while most bDMARD treatments comprised tumour necrosis factor inhibitors. IRs were 11.6 (95% CI: 9.3, 14.3) in JAKi- and 8.9 (95% CI: 7.4, 10.5) in bDMARD-treated groups. The adjusted HR comparing JAKis with bDMARDs was 1.40 (95% CI: 1.09, 1.80). An increase in the malignancy risk for JAKi vs bDMARD treatment could only be observed in treatment episodes lasting longer than 16 months. The risk appeared higher in some subgroups of patients, including those who started treatment aged ≥60 years, patients with ≥3 prior conventional synthetic DMARD treatments, and patients with high disease activity. Conclusions In this German observational cohort study, an overall small increase in malignancy risk for JAKi vs bDMARD treatment was observed, with more pronounced risks in some subgroups of patients. The observed risk should be carefully counterbalanced to the known malignancy risk associated with insufficient disease control.

Effect of depressive symptoms on treatment response in patients with axSpA: data from the RABBIT-SpA register

Abstract (Expand)

OBJECTIVES: This analysis aimed to evaluate the effect of depressive symptoms on treatment outcomes in patients with axial spondyloarthritis (axSpA), focusing on low disease activity (LDA) and inactive … disease (ID) at 3 and 6 months after the start of a new systemic therapy. METHODS: This analysis used data from the longitudinal, observational RABBIT-SpA register. Depressive symptoms were assessed using the WHO-5 Well-Being Index, with scores below 29 indicating moderate-to-severe symptoms. The treatment outcomes LDA and ID, based on the Axial Spondyloarthritis Disease Activity Score with C-reactive protein, were evaluated after 3 and 6 months. Logistic regression models adjusted for confounding variables, selected via a directed acyclic graph, were used to assess the relationship between baseline depressive symptoms and treatment outcomes. Multiple imputation was used to handle missing data. RESULTS: A total of 1755 patients with axSpA were included in the analysis. Moderate-to-severe depressive symptoms were present in 29% of patients at baseline. Fewer patients with moderate-to-severe depressive symptoms reached LDA or ID at 3 months and 6 months compared with those with no or mild symptoms. Logistic regression analysis showed that depressive symptoms were associated with lower odds of reaching LDA or ID at both time points. CONCLUSION: Depressive symptoms have a significant and independent negative effect on treatment response in patients with axSpA, particularly in achieving LDA and ID. These findings highlight the importance of routine mental health screening and treatment of depressive symptoms in axSpA management to optimise disease outcomes.
