Rheumatoid arthritis (RA) is a chronic autoimmune disorder that primarily affects the joints, causing pain, swelling, stiffness, and reduced mobility. It is characterized by inflammation of the synovial membrane, which can lead to erosion of the cartilage and bone within the joint. RA can also affect other organs and systems in the body. Research in the field of rheumatoid arthritis focuses on understanding the underlying causes of the disease, developing new and more effective treatments, and improving the quality of life for those living with RA. This includes studying the role of genetics, environmental factors, and the immune system in the development of RA, as well as investigating potential biomarkers for early detection and monitoring of the disease. Additionally, researchers are exploring new treatment options such as biologic therapies, disease-modifying antirheumatic drugs (DMARDs), and lifestyle interventions to manage symptoms and prevent joint damage in RA patients.
