Rheumatic arthritis is a reactive joint pain that occurs after a streptococcal infection. In addition to joint pain, common symptoms include mitral valve stenosis in some patients, skin erythema, and some patients may also exhibit symptoms such as chorea. Patients with rheumatoid arthritis often show symmetrical swelling and pain in the joints of both hands. Blood tests reveal significantly elevated levels of rheumatoid factor, anti-CCP antibodies, and AK antibodies. Inflammatory indicators such as erythrocyte sedimentation rate and C-reactive protein also tend to be significantly elevated. The main difference between rheumatic arthritis and rheumatoid arthritis is that rheumatic arthritis can involve cardiac and skin pathologies, while rheumatoid arthritis primarily manifests as joint-related pathologies.
