Abstract

Rheumatoid arthritis is a chronic disease that causes inflammation, swelling, pain, stiffness, and loss of function in the joints. The process begins in the synovium, a membrane that surrounds the joint, forming a protective sac. This sac is filled with a lubricating fluid called synovial fluid. In addition to protecting the joints, this fluid supplies nutrients and oxygen to cartilage, the smooth tissue that lines the ends of bones. Cartilage is made primarily of collagen, a structural protein in the body that forms a network of fibers that support the joints. In rheumatoid arthritis, the ongoing inflammatory process that affects the synovium gradually destroys the collagen, reducing the space in the joint and eventually destroying the bone itself. In progressive rheumatoid arthritis, cartilage destruction accelerates as fluid and inflammatory cells accumulate in the synovium, forming a pannus, a growth consisting of thickened synovial tissue.
