Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) consists of a group of small-vessel vasculitides that often present with organ-threatening or life-threatening manifestations. Current immunosuppressive treatments have improved survival and rates of remission, but are not curative, have frequent toxicities, and do not effectively prevent relapse. Clinical trials have established the role of rituximab, an anti-CD20 B cell-depleting monoclonal antibody, in both the remission-induction and maintenance phases of the disease and demonstrated that glucocorticoid doses can be substantially reduced from historical dosing levels without affecting treatment efficacy. Therapies that have the potential to be more effective and safer have become available or are under investigation. Avacopan, an oral C5a receptor antagonist, was approved as an adjunctive treatment for AAV and use of this drug in combination with rituximab or cyclophosphamide and markedly reduced glucocorticoid dosing demonstrated superior efficacy and potentially greater kidney recovery than prior standard of care. Other agents under study for treatment of AAV include next-generation anti-CD20 monoclonal antibodies, anti-CD19 chimeric antigen receptor T cells, novel complement inhibitors and agents that can target fibrosis. Alongside traditional randomized controlled trials with clinical endpoints, experimental medicine studies are focusing on mechanistic endpoints and disease biomarkers. This Review discusses current treatments and the advances in the management of AAV.

Autoimmune diseases are increasingly prevalent worldwide and disproportionately affect women of reproductive age, including during pregnancy. Given the association between autoimmune diseases, comorbidities, and risk factors for adverse pregnancy outcomes, we aimed to estimate the burden of autoimmune disease in pregnancy.

The incidence of rheumatoid arthritis (RA) is rising. However, its pathogenesis has not been fully understood, and the current therapeutic regimens are still limited. The aim of this study was to investigate the causal effect of plasma proteins on RA using Mendelian randomization (MR) analysis.

Chronic low back pain is a long-term recurrent condition. Interventions with sustained benefits are needed to reduce the associated personal and societal burden. We aimed to assess the long-term effectiveness of non-surgical interventions for reducing pain intensity and disability in adults with chronic low back pain.

Canakinumab, an IL-1β inhibitor, has demonstrated long-term efficacy and safety in patients with sJIA, FMF, TRAPS, and MKD/HIDS who experience inadequate disease control with conventional treatments. This non-interventional study aimed to gain insights into canakinumab use and treatment patterns for these diseases in Belgium.

To investigate the ex vivo IFN-γ release assay (IGRA) as a biomarker of SLE activity and disease outcome.

Our aim was to explore the effect of a single subcutaneous dose of CAM2043, a novel extended-release subcutaneous formulation of treprostinil, on finger temperature in patients with systemic sclerosis (SSc)-related Raynaud's phenomenon (RP).

To identify risk factors for spinal structural progression and determine the most significant impact on syndesmophytes growth and impaired spinal mobility in axSpA.

Idiopathic inflammatory myopathies (IIM) are autoimmune disorders characterised by muscle inflammation, high creatine kinase (CK) levels, and disability. Despite immunomodulating therapies, patients often experience progressive disease, resulting in refractory conditions or dependence on glucocorticoids (GC). This study addresses the efficacy and safety of immunoadsorption (IAS) in refractory IIM.

Regional variability in the effectiveness and safety of biologic therapies for rheumatoid arthritis (RA) and spondyloarthritis (SpA) underscores the need for comprehensive assessment. The aim of this study was to provide real-world evidence of the effectiveness and the safety of biologic for RA, SpA including psoriatic arthritis, in the daily clinical practice.

Osteoarthritis (OA) is a leading cause of lower limb disability worldwide, imposing significant socioeconomic and personal burden. Thus, many internationally recognised organisations have developed management guidelines for this condition. Among these, the National Institute for Health and Care Excellence (NICE) recommends four first-line approaches to osteoarthritis management: education, exercise, self-management, and weight management. Despite the development of guidelines, adherence to OA management recommendations appears to be suboptimal internationally, and little is known about guideline adherence in South Korea. This study aimed to explore whether research-based physiotherapy interventions for OA in South Korea align with the NICE guidelines.

The impact of primary Sjögren's syndrome (pSS) on adverse pregnancy outcomes remains a debated issue. Research suggests that newborns of mothers with pSS may be at a higher risk of developing heart conditions. This study aimed to examine the relationship between maternal pSS and the risk of cardiac disorders in neonates.

Given a substantial proportion of patients with ASS-ILD (anti-synthetase syndrome-associated interstitial lung disease) develop progressive pulmonary fibrosis (PPF), we aimed to investigate the clinical-radiographic characteristics and treatment in patients with or without anti-Jo-1 antibody.

Diffuse idiopathic skeletal hyperostosis (DISH) is a common incidental finding in medical imaging characterized by continuous vertebral ossification, which is associated with prevalent type 2 diabetes mellitus (T2DM). We hypothesized that incidental screen-detected DISH may be an actionable marker for incident diabetes screening and aimed to assess the absolute incidence rate (ratio) for T2DM in cardiovascular patients with and without DISH.
