Rheumatoid arthritis is primarily a chronic systemic autoimmune disease characterized by pain in multiple joints throughout the body. The causes of the disease are not yet clear, but it is believed to be related to a combination of genetic, infectious, and environmental factors. The main pathological basis of the disease is synovitis. It commonly occurs in individuals aged between 35 and 50, and is more prevalent in females, with a significantly higher incidence rate in women than in men. Additionally, this disease can lead to disability and loss of work capacity. Therefore, early diagnosis and standard treatment are crucial. Once the condition stabilizes, the dosage should be gradually reduced to maintain the disease in a stable state.
