Recurrent focal segmental glomerulosclerosis has a great impact on kidney graft survival. This retrospective study presents immunoadsorption-plasmapheresis treatment and outcome in our renal graft recipients with significant post-transplant proteinuria (>1 g/day) and focal segmental glomerulosclerosis in native kidneys. Recurrence was defined as occurrence of nephrotic range proteinuria or biopsy-confirmed diagnosis. Successful treatment was defined as sustained reduction of proteinuria to <1 g/day. From 2000 through 2011, 548 adult patients received kidney grafts from deceased donors. In 20 of these patients (3.6%) end-stage renal disease was a consequence of focal segmental glomerulosclerosis. Recurrence was confirmed in five of seven treated patients. Immunoadsorption-plasmapheresis treatment was successful in five patients (70%). Their age at disease diagnosis in native kidneys was 12 to 44 years. Time to end-stage renal disease was 3 to 14 years. Recipient age at transplantation was 21 to 61 years. Onset of significant proteinuria was 2 to 87 days after transplantation. Immunoadsorption or plasmapheresis started 1 to 7 days after recurrence of significant proteinuria. Treatment period was 1 to 103 months and 12 to 206 procedures were performed per patient. Follow-up period after cessation of plasmapheresis was 11 to 58 months. Final urine protein/creatinine ratio was 8.8 to 98.0 mg/mmol and final serum creatinine was 63 to 148 μmol/L. Follow-up after transplantation was 18 to 135 months. One patient was still on treatment. One graft was lost to recurrence. No serious adverse effects occurred during immunoadsorption and plasmapheresis. Immunoadsorption and plasmapheresis appears to be successful in the majority of patients, probably due to their early start.
复发性局灶节段性肾小球硬化对肾移植存活有重大影响。这项回顾性研究展示了免疫吸附 - 血浆置换疗法及其在我们肾移植受者中的治疗结果,这些受者移植后出现大量蛋白尿(>1克/天)且原肾存在局灶节段性肾小球硬化。复发定义为出现肾病范围蛋白尿或活检确诊。成功治疗定义为蛋白尿持续降至<1克/天。2000年至2011年期间,548名成年患者接受了来自已故供体的肾移植。其中20名患者(3.6%)终末期肾病是局灶节段性肾小球硬化的结果。7名接受治疗的患者中有5名复发得到证实。免疫吸附 - 血浆置换疗法在5名患者(70%)中取得成功。他们原肾疾病诊断时的年龄为12至44岁。至终末期肾病的时间为3至14年。移植时受者年龄为21至61岁。大量蛋白尿在移植后2至87天出现。在大量蛋白尿复发后1至7天开始免疫吸附或血浆置换。治疗期为1至103个月,每位患者进行了12至206次治疗程序。血浆置换停止后的随访期为11至58个月。最终尿蛋白/肌酐比值为8.8至98.0毫克/毫摩尔,最终血清肌酐为63至148微摩尔/升。移植后的随访期为18至135个月。1名患者仍在接受治疗。1个移植肾因复发而丢失。免疫吸附和血浆置换期间未发生严重不良反应。免疫吸附和血浆置换在大多数患者中似乎是成功的,可能是因为开始治疗较早。
