Excessive exercise is prohibited for patients in the acute stage of purpura nephritis because excessive exercise may lead to exacerbation of the disease; for patients in the stable stage of purpura nephritis, excessive exercise may have no effect on the body, but it is recommended to make an exercise program according to their own situation to avoid the disease recurrence. Anaphylactic purpura is a systemic vasculitis characterized by skin involvement, commonly seen in children, mostly self-limiting and 1/3 will recur. The disease can be combined with arthritis, abdominal pain and bloody stools, hematuria and proteinuria, and neurologic involvement. The histologic manifestations of the kidneys are consistent with IgA nephropathy. Treatment of the acute phase of the disease requires removal of the causative agent (e.g., infection, drugs or food), intensive rest, analgesia and anti-allergy (cetirizine), and hormone (prednisone acetate) and immunosuppressant (cyclophosphamide) therapy, if necessary. For patients in the acute stage, it is recommended to strengthen rest to avoid exacerbation of the disease due to excessive exercise. For patients in the stable stage, excessive exercise may not have much effect on the body, but it is recommended that patients adjust the amount of exercise according to their own conditions, and at the same time, pay attention to observe whether there is an increase in urinary foam, limb edema and other conditions after exercise, and if necessary, review the urine routine, urinary proteins and other indicators, to assess the condition. Patients with purpura nephritis are advised to consult regular hospitals for standardized treatment and reasonable exercise instructions under the guidance of physicians.
