The induction of autoimmune diseases during tumour necrosis factor-alpha inhibitor (TNFi) usage has been described. Herein, we report a rare case of a 49-year-old woman with antimelanoma differentiation-associated gene 5 (MDA5) antibody (Ab)-positive dermatomyositis (DM), which developed 5 weeks after the introduction of an etanercept biosimilar to rheumatoid arthritis (RA). Four of the five known cases, including ours, of anti-MDA5Ab-positive DM complicated with RA revealed anti-MDA5Ab-positive DM following TNFi usage. When patients with RA are diagnosed with interstitial lung disease during TNFi usage, anti-MDA5 Ab-positive DM could be a differential diagnosis.

Objective: We aimed to evaluate tumor necrosis factor inhibitor (TNFi) usage patterns in pregnant women with rheumatoid arthritis (RA), radiographic axial spondyloarthritis (r-axSpA), psoriatic arthritis (PsA), psoriasis (PsO), and inflammatory bowel diseases (IBD), and to compare corticosteroid use in those discontinuing TNFi at specific gestational timepoints vs those continuing throughout gestation.
Methods: We analyzed pregnancies resulting in a live birth among women with RA, r-axSpA, PsA, PsO, and/or IBD, aged 15-45 years, who were hospitalized for delivery between January 2011 and December 2021, using the MarketScan commercial claims database. TNFi exposure was defined as ≥ 1 filled prescription or infusion procedure claim for a TNFi.

Background: Rheumatoid arthritis (RA) significantly impacts bone health, leading to osteoporosis and increased fracture risks. This study aims to compare the effects of TNF-α and IL-6 inhibitors on the incidence of fractures, osteoporosis, and mortality among RA patients.
Methods: We conducted a retrospective cohort study using the TriNetX database, spanning from January 1, 2015, to December 31, 2022.

Rheumatoid arthritis (RA) is a chronic inflammatory disease that primarily affects the synovial joint linings, resulting in progressive disability, increased mortality, and considerable economic costs. Early treatment with disease-modifying antirheumatic medications (DMARDs) can significantly improve the overall outlook for people with RA. Contemporary pharmaceutical interventions, encompassing standard, biological, and emerging small molecule disease- modifying anti-rheumatic medications continue to be the cornerstone of RA management, with substantial advancements made in the pursuit of achieving remission from the disease and preventing joint deformities.

This retrospective cohort study included all user of tumor necrosis factor-α inhibitors (TNFi), including etanercept, infliximab, adalimumab, and golimumab, among Korean patients with psoriasis and rheumatoid arthritis (N of user = 7,645) and the non-user who was diagnosed with same diseases, never used TNFi, and was served as the reference. Cumulative usage of TNFi was calculated between the newly diagnosed date and index date (2-year from the diagnosed date). Adjusted hazard ratio (aHR [95% confidence intervals (CIs)]) for colorectal, liver, lung, kidney, breast, and thyroid cancer were not significantly increased or decreased: 0.
