Allergic purpura nephritis can basically be the same as normal people after clinical cure, but because purpura nephritis is easy to recur, so you also have to pay attention to avoid recurrence factors in daily life. Allergic purpura nephritis (HSPN) is the manifestation of allergic purpura (HSP) when kidney damage occurs and is the most common secondary glomerulonephritis in children. It often presents with hematuria, proteinuria, and in some cases, hypertension and renal insufficiency. The overall prognosis of HSPN is favorable, but clinical and renal pathology can vary, and response to treatment and prognosis vary widely. After clinical cure of allergic purpura nephritis, attention should be paid to the prevention of upper respiratory tract infections, removal of chronic infectious lesions, such as pharyngitis, chronic tonsillitis, and active search for possible allergens to avoid re-exposure, which can lead to the recurrence of purpura and aggravate renal damage. Patients with purpura nephritis need to consult a regular hospital and follow the doctor’s instructions for regular review and standardized treatment.
