Reactive (inflammatory) arthritis has been known for many years to follow genital infection with the intracellular bacterial pathogen Chlamydia trachomatis in some individuals. Recent studies from several groups have demonstrated that a related bacterium, the respiratory pathogen Chlamydia pneumoniae, can elicit a similar arthritis. Studies of these organisms, and of a set of gastrointestinal pathogens also associated with engendering inflammatory arthritis, have been relatively extensive. However, reports focusing on coinfections with these and/or other organisms, and the effects of such coinfections on the host immune and other systems, have been rare. In this article, we review the extant data regarding infections by multiple pathogens in the joint as they relate to engendering arthritis, and we suggest a number of research areas that must be given a high priority if we are to understand, and therefore to treat in an effective manner, such arthritides.

CD28 is a costimulatory receptor that provides the second signal necessary for T-cell activation and is associated with diseases, including rheumatoid arthritis, asthma, and cancer. Targeting CD28 is crucial for both functional bioanalysis and therapeutic development. Molecular probes, particularly fluorescent probes, can enhance our understanding of CD28's cellular roles.

Purpose Of Review: Our purpose was to discuss the advantages and disadvantages of various noninvasive imaging modalities in the evaluation of cardiovascular disease (CVD) in patients with autoimmune rheumatic diseases (ARDs). The detailed knowledge of imaging modalities will facilitate the diagnosis and follow up of CVD in ARDs.
Recent Findings: Autoimmune Rheumatic Diseases (ARDs) are characterized by alterations in immunoregulatory system of the body.

Objectives: The purpose of the present study was to investigate the differential impact of disease activity and severity on functional status and patient satisfaction in rheumatoid arthritis (RA) using cluster analysis on data from the FRANK registry.
Methods: Data from 3,619 RA patients in the FRANK registry were analysed. Patients were grouped using hierarchical and k-means cluster analyses based on age, physician's global assessment (PhGA), patient's pain assessment (PtPA), and Steinbrocker stage.

Introduction: Celiac disease (CD) affects the small intestine, leading to a progressive disappearance of intestinal villi, and can be found in association with several other autoimmune and inflammatory conditions. The main objective of this study was to determine the prevalence and the clinical significance of anti-transglutaminase and anti-endomysium antibodies in patients diagnosed with early rheumatoid arthritis (RA) and spondyloarthritis (SpA).
Methods: We measured anti-transglutaminase and anti-endomysium antibodies in biobanked serum samples at inclusion in two French prospective multicenter cohorts of patients with suspected early rheumatoid arthritis (ESPOIR, n = 713) and spondyloarthritis (DESIR, n = 709).

Introduction/objectives: The study aimed to determine whether in children with newly diagnosed juvenile idiopathic arthritis (JIA) hepatitis B surface antibody (anti-HBs) differs from healthy children and to see whether the revaccination is safe and effective under JIA treatment.
Methods: Patients who were followed up with a diagnosis of JIA between January 2020 and February 2024 were included. The control group consisted of healthy children matched for age and gender.
