The diagnostic criteria for rheumatoid arthritis include the following aspects: The first is symmetrical joint pain, primarily characterized by tenderness and swelling in the metacarpophalangeal joints, proximal interphalangeal joints, and both wrists. Secondly, it also includes abnormalities in inflammation markers, which comprise erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), along with abnormalities in certain antibodies, mainly rheumatoid factor, CCP antibodies, and AKA antibodies. If the above symptoms are present, and these inflammation markers and antibodies are found to be abnormal upon blood testing, a diagnosis of rheumatoid arthritis can be made.

Is rheumatoid arthritis serious?

Patients with rheumatoid arthritis, if treated reasonably and formally, can achieve clinical remission, so in this sense, rheumatoid arthritis is not severe. However, if patients do not adhere to formal treatment for a long time, after a long period, they may develop joint deformities and ankylosis, resulting in disability. From this perspective, rheumatoid arthritis should be taken seriously. Commonly used drugs for treating rheumatoid arthritis include anti-inflammatory pain relievers, with non-steroidal pain relievers being the most commonly used, such as sustained-release diclofenac sodium tablets. The most important step in treating rheumatoid arthritis is the selection of immunosuppressants, with common immunosuppressants including methotrexate and leflunomide. (Medication should be used under the guidance of a doctor based on specific circumstances.)

Rheumatoid arthritis skin manifestations

Rheumatoid arthritis does not have specific skin manifestations. Rheumatoid arthritis is an immune-mediated erosive arthritis, clinically characterized by systemic symmetrical multiple joint swelling and pain, accompanied by morning stiffness, often lasting for more than an hour. Rheumatoid arthritis can affect the proximal interphalangeal joints and middle joints of both hands, as well as both wrists, elbows, shoulders, ankles, knees, and other joints. Some patients may experience involvement of the temporomandibular joint. Rheumatoid arthritis can also have extrarticular manifestations, such as affecting the hematological system, which may result in mild to moderate anemia, or affecting the lungs, which can lead to interstitial pneumonia or pulmonary fibrosis.

Is joint pain rheumatoid arthritis?

Firstly, it should be noted that there are many causes of joint pain in clinical practice, and it is not necessarily caused by rheumatoid arthritis. Of course, rheumatoid arthritis can also cause joint pain in patients. In addition, there are some other reasons, for example, local joint bacterial infection in patients can also cause joint pain. Furthermore, joint injuries leading to fractures, dislocations, soft tissue damage, ligament injuries, and meniscus injuries can also cause joint pain. Additionally, the presence of osteoarthritis or gouty arthritis can similarly lead to joint pain in patients.

The difference between osteoarthritis and rheumatoid arthritis.

Osteoarthritis is primarily a degenerative joint disease, most commonly occurring in weight-bearing joints and the distal joints of both hands. Therefore, if there is pain in the distal joints of the hands or in joints like the knee, it may be osteoarthritis. Rheumatoid arthritis mainly affects the metacarpophalangeal joints, proximal interphalangeal joints, and both wrists. It is also important to distinguish that in patients with osteoarthritis, inflammation indicators such as sedimentation rate, C-reactive protein, and endocrine factors are usually normal. However, in patients with rheumatoid arthritis, these indicators, including sedimentation rate, C-reactive protein, and rheumatoid factor, are abnormally elevated.

Rheumatoid arthritis commonly occurs at what age?

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.
