Some adolescents with grade III purpura nephritis may be cured and achieve complete remission, but they are prone to relapse and may eventually develop chronic kidney disease.
Allergic purpura is a vasculitis that mainly involves small blood vessels, especially capillaries, small veins and small arteries. The vast majority of patients with purpura have skin damage, accompanied by kidney damage known as purpura nephritis.
A proportion of adolescents with purpura fulminans grade III achieve complete remission and can be cured. Long-term follow-up from the onset of the disease up to a maximum of 20 years reveals that some patients with both nephrotic and nephritic syndromes eventually develop chronic kidney disease, and others rapidly progress to end-stage renal disease.
Adolescents with allergic purpura nephritis grade III should go to the hospital for timely consultation, regular review and treatment under the guidance of professional physicians.
