Purpura nephritis is not serious for most patients. This is because for most patients, purpura nephritis is a self-limiting disease. Therefore, for most patients with mild clinical manifestations and transient abnormal urinalysis, no special treatment is needed, while patients can get better on their own in a short period of time. For patients with clear renal damage, if there is more proteinuria, the use of antihypertensive drugs such as Prilosec or Satan can be recommended to lower blood pressure as well as urine protein. If the kidney damage is more severe, hormones can be used for treatment. In patients with more crescent formation, methylprednisolone shock therapy or shock therapy followed by glucocorticoids combined with cytotoxic drugs and immunosuppressive agents may be used. The short-term and long-term prognosis of patients is relatively good, especially in pediatric patients, and the prognosis of purpura nephritis is mostly good.
