Rheumatoid arthritis is a chronic, progressive, aggressive, autoimmune disease. It presents with progressive joint destruction, which can lead to joint deformity in advanced stages and a high disability rate, with a 3-year disability rate of 75%. The prevalence is 0.33%-1.0%, with 5 million patients in China. When it comes to arthritis, people are used to associating it with diseases of the elderly. Rheumatoid arthritis is not the exclusive preserve of the elderly, the peak incidence is between 30-50 years old, and many rheumatoid arthritis patients are young people in their 20s and 30s. It is believed that rheumatism is caused by wind and cold, humidity, etc. However, rheumatoid arthritis is an autoimmune disease, the cause of which is unknown, not only because of the cold and humidity of the environment, but also because of infection, endocrine and genetic factors. Common manifestations of rheumatoid arthritis: Early on, swelling and pain of joints and morning stiffness can occur, mainly in small joints, such as fingers, wrists, toes and other joints. Some patients can also involve the temporomandibular joints and have difficulty in eating and chewing. Without regular treatment, joint deformity and even disability can occur in the late stage, which can seriously affect the life and work of patients. In addition, some patients can develop extra-articular manifestations, such as rheumatoid nodules, vasculitis, organ damage (lung, nervous system, kidney, etc.), anemia, weight loss, and hypothermia. Laboratory tests may show positive rheumatoid factor and anti-cyclic citrulline antibodies, elevated blood sedimentation and C-reactive protein, and abnormal manifestations on joint X-rays, MR, and ultrasound. Not all patients with rheumatoid arthritis have a positive rheumatoid factor, nor does the presence of a positive rheumatoid factor necessarily mean rheumatoid arthritis. Some normal people, especially the elderly, can have a positive low titer, and clinical symptoms and joint imaging should be combined to determine this. There is no specific cure for rheumatoid arthritis. The main goal of treatment is to reduce joint swelling and pain, morning stiffness and other symptoms, control disease progression, prevent or reduce joint bone destruction, and promote joint function repair. Early diagnosis and early treatment are emphasized. Therefore, once rheumatoid arthritis is diagnosed, it is necessary to seek regular and systematic treatment at an early stage, and not to blindly believe in the so-called biased and secret prescriptions. The same rheumatoid arthritis is treated individually, but the treatment plan may not be the same for different patients, so you should not copy other patients’ treatment plans. In the acute phase of rheumatoid arthritis, bed rest is recommended to reduce the movement of diseased joints. During the recovery period, attention should be paid to functional joint exercises, and physical therapy can also be used. Also pay attention to strengthening nutrition, timely treatment of chronic infections in the body, avoiding cold and moisture to avoid aggravating the disease or causing a relapse. Medication includes anti-inflammatory painkillers, condition control drugs, hormones, Chinese medicine, etc. During the treatment process, attention should also be paid to regular review to evaluate the efficacy of the treatment plan and the occurrence of adverse reactions according to the results of the review, and to decide the next treatment plan. Generally, the blood and urine routine, blood sedimentation, C-reactive protein, etc. should be reviewed in about one month, and the liver and kidney function should be reviewed in about three months.
