Rheumatoid arthritis is caused by what?
Rheumatic arthritis is a type of infectious arthritis caused by streptococcal infection and is one of the clinical manifestations of rheumatism. It primarily presents as migratory pain in large joints, most commonly affecting the large joints of the lower limbs, such as the knees, ankles, wrists, etc. Since rheumatic arthritis is related to streptococcal infection, treatment mainly involves the use of penicillin drugs, commonly long-acting penicillin, which requires strict adherence to the treatment course to completely cure the streptococcal infection. During the acute phase, joint pain often occurs, hence the common use of non-steroidal anti-inflammatory drugs, such as diclofenac sodium and etoricoxib, to alleviate symptoms of pain. During acute episodes, bed rest is necessary, with attention to joint immobilization. During the remission period, getting out of bed and exercising is encouraged to restore joint function and flexibility. (Please use medications under the guidance of a professional physician; do not self-medicate.)

How to test for rheumatic fever?
Rheumatic fever is a systemic connective tissue disorder occurring one to four weeks after an infection by Group A Streptococcus, primarily affecting the heart and joints, and commonly infects children and adolescents. The usual clinical manifestations include carditis, polyarthritis, chorea, erythema marginatum, subcutaneous nodules, joint pain, and fever. Common laboratory tests for this disease include: 1. Complete blood count, often showing mild anemia and a slight increase in white blood cell count. 2. Elevated erythrocyte sedimentation rate. 3. Elevated C-reactive protein. 4. Antistreptolysin-O antibodies often greater than 500 units. 5. Positive throat swab culture. 6. Echocardiogram, which may show vegetations.
