The term reactive arthritis (RA) refers to an inflammatory joint disease in the absence of bacteria in the joint, but which is caused by a distant extra-articular infection. They occur as a result of a variety of infections, which are essentially genital or gastro-intestinal in subjects with a particular genetic predisposition characterized by the presence of the HLA-B27 antigen or one of the CREG group of antigens (B7 - B27 - BW22 - BW42). The most complete clinical expression of reactive arthritis is the Fiessinger-Leroy-Reiter syndrome. Apart from the reactive arthritis with a generally accepted aetiology such as those following infections of the genital tract (Chlamydia trachomatis, Ureaplasma urealyticum or of the gastrointestinal tract: Yersinia enterocolitica and pseudotuberculosis, Shigella flexneri, Salmonella minor, Campylobacter jejuni), the authors discuss the possibility of including, in a broader definition of RA, post-streptococcal arthritis and cases of arthritis following gonococcal, meningococcal and Brucella infections. RA does not always have a favourable clinical course. It is not exceptional to see a picture of recurrences with progression towards chronic inflammatory rheumatism.

Seaweeds have been utilized as food, fodder, fertilizer, and medicine since ancient times; nevertheless, they have received only a little attention. In the current work, we extracted the sulfated polysaccharide from a marine source and investigated its anti-arthritic potential . The isolated and freeze-dried polysaccharide was tested for acute oral toxicity based on OECD 423.

Objective: Fatigue is important for patients with rheumatoid arthritis (RA) but is poorly understood. We sought to study associations of fatigue with clinical features, disease activity, and synovial histology.
Methods: Patients meeting the American College of Rheumatology/EULAR 1987 and/or 2010 RA criteria were recruited before elective total joint replacement.

Rheumatoid arthritis (RA) is a common chronic systemic autoimmune disease that often results in irreversible joint erosion and disability. Methotrexate (MTX) is the first-line drug against RA, but the significant side effects of long-term administration limit its use. Therefore, new therapeutic strategies are needed for treating RA.

Objective: To assess CXC chemokine receptor 5 (CXCR5) circulating DNA methylation differences in autoimmune rheumatic diseases and their relation with clinical features.
Methods: Targeted methylation sequencing was performed using peripheral blood from 164 rheumatoid arthritis (RA), 30 systemic lupus erythematosus (SLE), 30 ankylosing spondylitis (AS), 30 psoriatic arthritis (PsA), 24 Sjögren's syndrome (SS) patients, and 30 healthy controls (HC).
Results: Significant differences in CXCR5 cg19599951 methylation were found between RA and HC, as well as AS and SLE.

Reconstructing large, inflammatory maxillofacial defects using stem cell-based therapy faces challenges from adverse microenvironments, including high levels of reactive oxygen species (ROS), inadequate oxygen, and intensive inflammation. Here, inspired by the reaction mechanisms of intracellular antioxidant defense systems, we propose the de novo design of an artificial antioxidase using Ru-doped layered double hydroxide (Ru-hydroxide) for efficient redox homeostasis and maxillofacial bone regeneration. Our studies demonstrate that Ru-hydroxide consists hydroxyls-synergistic monoatomic Ru centers, which efficiently react with oxygen species and collaborate with hydroxyls for rapid proton and electron transfer, thus exhibiting efficient, broad-spectrum, and robust ROS scavenging performance.
