Key purpura is a type of allergic purpura. The most obvious symptom of articular purpura is joint pain, which often causes swelling and pain in the knees, ankles, wrists and other parts. This situation is very harmful to patients and often affects their normal life and work. At this time, you must go to the hospital for examination and treatment in time. You should also pay attention to health care to avoid greater impact.

What are the symptoms of arthritis purpura

The clinical characteristics are swelling and pain in the knees, ankles, elbows, and wrists before and after the onset of skin purpura. The pain and swelling in the knees are the most significant and may be migratory and recurrent. Physical examination shows obvious redness, swelling, heat, pain, and dysfunction in the affected joints, with a small amount of fluid in the joint cavity.

A careful examination can also reveal that the 4 limbs, especially the lower limbs and buttocks, have skin petechiae, erythema or urticaria-like changes of varying sizes and do not fade when pressed. Laboratory tests show abnormal changes with diagnostic significance, such as positive capillary fragility test, accelerated erythrocyte sedimentation rate and positive C-reactive protein. The above are the main basis for doctors to diagnose arthritis of allergic purpura.

Treatment method: Since joint allergic purpura is relatively rare, it is easy to be misdiagnosed as rheumatoid arthritis or other joint diseases, especially when joint pain and swelling occur before skin purpura in some patients.

Therefore, when children have joint swelling and pain again after recovering from a cold, they should consider rheumatoid arthritis as well as arthritis-type allergic purpura and conduct a comprehensive examination in a timely manner. In particular, attention should be paid to the presence of skin petechiae, erythema, and urticaria-like changes, and the results of capillary fragility tests, so as to make a clear diagnosis and provide appropriate treatment in a timely manner.

The prognosis of joint-type allergic purpura is good. After effective treatment, the swelling and pain of the joints will subside in about 3-5 days, and there will be no sequelae after the swelling subsides. However, it is necessary to be vigilant about its tendency to relapse and strengthen the prevention link. The main principle of prevention is to find possible allergens (such as upper respiratory tract infection, certain foods such as fish, shrimp, crab, eggs, etc., certain drugs such as penicillin, streptomycin, non-steroidal anti-inflammatory drugs and quinine, etc.) and avoid them in the future.

Among them, upper respiratory tract infection is the most common cause of allergic purpura in children. Therefore, keeping warm, avoiding cold and rain, preventing food accumulation, increasing exercise, and improving the body's resistance and immunity become the main preventive measures after the child is cured.
