Rheumatoid arthritis (RA) is a chronic disease with an autoimmunological background. RA is mostly characterized by systemic inflammation and injuries of synovial joints. There is a hypothesis that bacterial infections may be connected with development of the disease. It has been suggested that molecular mimicry between bacterial and human antigens may be one of possible mechanisms of RA development. One of potential antigens involved in this mechanism is urease - enzyme with high structural conservatism, occurring in pathogenic and commensal bacteria. We found that the level of antibodies against peptide mimicking urease "flap" region is significantly higher in sera from patients with rheumatoid arthritis in comparison with volunteer blood donor sera. We also observed that antibodies present in RA sera may bind not only specific peptide antigens but also peptides with a slightly different structure.

Rheumatoid arthritis (RA) is a systemic, progressive illness marked by persistent synovitis that causes substantial functional disability. Treatment delays frequently affect health-related quality of life. Extra-articular features are prevalent findings in RA, which leads to significant morbidity and mortality.

Objectives: Copaiba essential oil (CEO) is obtained through the distillation of copaiba balsam and has been used in the traditional medicine to treat inflammatory conditions. However, the highly lipophilic nature of CEO restricts its pharmaceutical use. This study evaluated the effect of CEO, carried in a self-nanoemulsifying drug delivery system (SNEDDS), on articular and systemic inflammation and liver changes in Holtzman rats with Freund's adjuvant-induced arthritis.

Objective: Interstitial lung disease (ILD) is rare, but it is one of the most frequent extra-articular manifestations and a relevant cause of morbidity and mortality in rheumatoid arthritis (RA). Over the past few years, Janus kinase inhibitors (JAKis) have been reported to have promising efficacy in the treatment of active RA, but recent concerns have been raised about their safety profile, namely malignancy and cardiovascular disease, limiting their use to certain patient categories.
Methods: The objective of this narrative review is to summarize the current evidence of the efficacy and safety of JAKis in RA-ILD management, investigating a possible emerging role for this drug class in such subset of patients.
