Rheumatic diseases, in a broad sense, are rheumatic as long as they involve chronic pain in muscles and joints throughout the body, and even include tumorigenic lesions. Nowadays, we often talk about rheumatic diseases, mainly referring to diffuse connective tissue diseases. Patients, you may not know these proper names, just know that it is a complex class of systemic immune diseases on the line. What are the common symptoms of rheumatic diseases? Long-term unexplained fever, joint swelling and pain, rash, skin ulcers, hair loss, anemia, thrombocytopenia, leukopenia, pleural fluid, pericardial effusion, nephritis, etc. are all common manifestations of rheumatic diseases. General primary care doctors have little understanding of these diseases, even non-specialist doctors in large hospitals are only considered to understand, rheumatologists can only know a general situation, I think there are few authorities, at most experts. How to treat rheumatism? In short, I mainly glucocorticoids and immunosuppressive drugs. Too specialized, it is best to look at what rheumatism patients are eating on the line. In fact, I think one category is represented by systemic lupus erythematosus, where hormones are mainly applied, and another category is represented by rheumatoid arthritis, where anti-rheumatic drugs (mostly cytotoxic drugs with mild side effects, which can also be called immunosuppressive drugs) are mainly applied to change the course of the disease. The former category often requires the combination of immunosuppressive drugs. What laboratory tests are required for rheumatic diseases? Because rheumatism is mostly a systemic disease, a comprehensive and systematic examination is mostly required. Blood sedimentation, anti-O, C-reactive protein, and rheumatoid factor alone are definitely not enough, and immunological tests are needed. What is the prognosis of rheumatic diseases? Rheumatism is a chronic, systemic disease that cannot be cured overnight and requires long-term treatment. Any treatment that claims to be able to “cure” the disease is a scam. A good prognosis requires long-term cooperation between doctor and patient.
