摘要目的 了解狼疮肾炎(LN)伴血栓性血小板减少性紫癜(TTP)的临床病理特征、治疗及预后情况.方法 回顾性分析8例确诊的LN伴TTP患者的临床病理特征、治疗方案及预后.结果 8例患者临床上均具有典型血栓性微血管性溶血性贫血、血小板减少、中枢神经系统症状和肾功能损害,其中6例患者伴有发热.8例患者肾脏病变以急进性肾炎起病,1例伴有持续性肉眼血尿,病理上患者均以血管病变为主,表现为血栓性微血管病(TMA)样病变.8例患者均给予免疫抑制剂治疗,7例行血液净化治疗,3例患者行血浆置换和(或)免疫吸附治疗.8例患者中,1例失访,7例均随访1年以上,其中1例死亡,3例行腹膜透析,后1例摆脱透析,1例改血液透析,其余3例肾功能稳定.结论 LN合并TTP的临床及病理重、进展快、预后差,应早期诊断,早期积极治疗.

abstractsObjective To investigate the clinical-pathological features, treatment and prognosis of thrombotic thrombocytopenic purpura in patients with lupus nephritis (LN). Methods A retrospective ana-lysis was carried out based on the clinical-pathological data for the treatment and prognosis of eight patients with LN related TIP. All patients had thrombocytopenia and hemolytic anemia, neurological symptoms and renal dysfunction. Six patients had fever. Results All 8 patients had sudden-onset of rapid progressive glomeurlonephritis (RPGN), one patient with continuous gross hematuria, the pathological features of these patients revealed TMA lesions. Immune suppressive therapy was initiated and blood purification therapy were applied in seven patients. Three cases had plasmapheresis and (or) immunoabsorption. One case was lost during follow-up, the other seven patients were followed with period at one year. One patient died, three patients went into peritoneal dialysis in which one of them was changed to hemodialysis finally. The other three patients had stable renal function. Conclusion The LN patients with TTP had severe clinical-patho-logical changes, rapid progressive and poor outcome, so we should diagnose and treat these patients as early as possible.
