摘要 40岁男性患者,既往临床表现肾病综合征,自体肾活检诊断膜性肾病(MN),抗磷脂酶A2受体(PLA2R)抗体滴度阳性,起病后7年进入慢性肾衰竭行血液透析(HD)治疗,HD治疗5个月后接受亲属活体肾移植,术前抗PLA2R抗体阳性。移植术后6个月尿蛋白阳性,抗PLA2R抗体滴度升高,移植肾活检提示MN复发。以抗CD20单克隆抗体(美罗华)375 mg/m^2治疗后,患者蛋白尿转阴,抗PLA2R抗体滴度下降。 A middle-aged male was admitted for nephritic syndrome, and diagnosed membranous nephropathy (MN) by renal biopsy of native kidney as well as phospholipase A2 receptor (PLA2R) antibody positive. There was no secondary available factor. Graft biopsy-proven recurrent MN developed at 5 months post-transplant. The levels of proteiniura and serum PLA2R antibody were decreased after the treatment of rituximab.
