Rheumatoid arthritis (RA) in adult patients, there is contradictory evidence regarding Abatacept's safety profile (ABA). This study aims to assess the safety and efficacy of ABA in adult patients in Saudi Arabia.

The reported incidence and mortality of connective tissue diseases (CTDs) in England has been inconsistent in the literature. Our objective was to describe current trends in the incidence and mortality of systemic lupus erythematous (SLE), Sjögren's disease (SjD), systemic sclerosis (SSc), idiopathic inflammatory myopathies (IIM) and mixed connective tissue disease (MCTD).

To evaluate upadacitinib (UPA) effectiveness on axial and peripheral manifestations of PsA by assessing the proportion of patients achieving low disease activity (LDA) and inactive disease (ID) status for axial involvement, and MDA and DAPSA-defined remission/LDA for peripheral domain.

Osteoarthritis of the hip is a leading cause of chronic disability. The cycling and education intervention (CLEAT) trial aimed to compare the clinical and cost-effectiveness of the cycling against hip pain (CHAIN) intervention, a group-based cycling and education programme, with usual physiotherapy care for patients with hip osteoarthritis referred for physiotherapy at a UK hospital.

Immune checkpoint inhibitors (ICIs) have become a cornerstone in the treatment of metastatic melanoma. Several case reports have documented IgG4-related disease (IgG4-RD) as an adverse event following ICI therapy. Here we report the first instance of interstitial nephritis associated with IgG4-RD as an immune-related adverse event (irAE) following ICI treatment.

Pneumococcal vaccination is recommended for patients with rheumatoid arthritis. Because immunosuppressant therapies for rheumatoid arthritis hinder vaccine efficacy, vaccination should be administered before initiating immunosuppressive drugs. We aimed to compare humoral responses in patients with rheumatoid arthritis receiving the pneumococcal 13-valent conjugate vaccine (PCV13) before methotrexate initiation or simultaneously.

To identify modifiable risk factors associated with progression of hearing impairment from a longitudinal cohort of anti-IL-1-treated children and adults with Cryopyrin-Associated Periodic Syndromes (CAPS) and explore real-life barriers to optimal long-term management.

Anti-interleukin-1 therapies are effective for colchicine-resistant FMF, yet data on optimal duration in pediatric patients remain limited. A previous multicentre study showed favourable outcomes with a standardized canakinumab dose extension protocol, though follow-up was short. This study aimed to assess the long-term outcomes of this protocol.

This study aims to examine the indications for paediatric rheumatologists to use biologic therapies in childhood Behçet's disease (BD), as well as the efficacy, safety and remission rates of such treatments. We also compare demographic and clinical characteristics of Turkish and European cohorts.

Combined pulmonary fibrosis and emphysema (CPFE) predicts unfavourable outcomes in systemic sclerosis (SSc). CPFE and emphysema are associated with pulmonary function tests (PFTs) abnormalities. As screening algorithms for pulmonary hypertension include PFTs, we aimed to assess whether CPFE and emphysema affect the performance of the DETECT algorithm to select patients for right-heart catheterization (RHC).

The gut microbiome forms an ecosystem that provides the host with numerous benefits such as digestion with nutrient generation, protection from pathogens and immune system maturation. Alterations in the microbial ecosystem associated with rheumatoid arthritis and spondyloarthritis have led to the gut-joint hypothesis, which postulates that these ecological changes cause immune dysfunction that contributes to the development of arthritis. Mechanisms by which dysbiosis might trigger arthritis include molecular mimicry, dysregulation of mucosal immunity, microbial translocation, production of immunomodulatory metabolites and immune cell trafficking. We discuss the data supporting each of these mechanisms, and highlight misconceptions, limitations and gaps in knowledge. In particular, we advise against the term 'leaky-gut' as the mechanisms and effects on the immune system of intestinal permeability and bacterial translocation are distinct. Nevertheless, rheumatoid arthritis and spondyloarthritis possibly result from the convergence of multiple pathways that could be unique to subgroups of individuals within these diseases. To move the field forward, each mechanism needs to be considered through the use of model organisms and interventional trials, individually and in concert.
