本文对紫癜性肾炎31例进行1～11年肾功能随访。认为:发病年龄>10岁,紫癜到肾炎出现时间>1月或紫癜在肾炎发生后仍反复出现,临床上肾炎综合征并持续高血压、肾功能受损害者,预后差。对持续大量蛋白尿,其蛋白选择性差,肾功不全的严重病例,及早采用免疫抑制剂并加用抗凝剂、抗血小板凝聚剂治疗,可望减少或延长进入终末期肾功能衰竭的时间。 In this paper, 31 cases of purpura nephritis for 1 to 11 years of renal function follow-up. That: the age of onset> 10 years old, purpura to nephritis appear> January or purpura nephritis occurs again and again, clinical nephritic syndrome and persistent hypertension, impaired renal function, the prognosis is poor. Serious cases of proteinuria, the poor protein selectivity, severe cases of renal insufficiency, early adoptive immunosuppressive agents plus anticoagulants, antiplatelet coagulant therapy, is expected to reduce or prolong the time to enter the terminal renal failure.
