Autoimmune disorders are complex and can significantly impact various parts of the body, including the joints, muscles, and nerves. Among them, autoimmune arthritis stands out, with Rheumatoid Arthritis (RA) being a prominent example. RA is a form of autoimmune arthritis affecting approximately 1.28 to 1.36 million adults in the United States, predominantly women. This condition commonly targets the joints in the hands, wrists, and knees, leading to chronic pain, lack of balance, and potential joint deformity.
Multiple sclerosis, rheumatoid arthritis, and polymyalgia rheumatica represent just a few autoimmune disorders influencing the joints. In addition to affecting joints, many autoimmune disorders impact connective tissues and various organs. Connective tissues provide structural support to joints, tendons, ligaments, and blood vessels. Autoimmune rheumatic disorders, such as autoimmune myositis and eosinophilic fasciitis, are examples in this category. They can lead to muscle inflammation (myositis), debilitating muscle weakness, and sometimes tenderness, predominantly affecting adults aged 40 to 60 and children aged 5 to 15 years.
In the case of rheumatoid arthritis, the immune system mistakenly attacks healthy tissue in joints, potentially extending its effects to the heart, lungs, nerves, eyes, and skin. Factors such as being female, obesity, and infections may increase the risk of developing an autoimmune disease. Symptoms can vary, with diseases of the joints and muscles manifesting as muscle aches, joint pain, stiffness, swelling, and muscle weakness.
RA is a chronic and systemic autoimmune disease, characterized by inflammation of the synovial joints, potentially leading to progressive disability and premature death. Chronic inflammation in the joints may damage cartilage, bones, tendons, ligaments, and nerves, resulting in a variety of symptoms. Synovitis, an inflammation of the joint lining, is a common consequence, causing joint pain and swelling.
