摘要 目的 总结儿童肾移植指征性移植肾穿刺病理特征,分析移植肾并发症和特点.方法 回顾性分析2003年1月至2017年3月单中心儿童肾移植的指征性移植肾穿刺病理资料.结果 35例患者共43例次移植肾行病理穿刺,以排斥反应(11/35,31.4%)和新发/复发肾病(9/35,25.7%)为主.排斥反应包括急性T淋巴细胞排斥反应(8/11,72.7%)和急性抗体介导排斥反应(3/11,27.3%),肾病包括IgA肾病(5/9,55.6%)、局灶性节段性肾小球硬化(2/9,22.2%)、溶血尿毒综合症(1/9,11.1%)等.其他穿刺病理检查发现包括间质性肾炎(4/35,11.4%)、BK病毒相关性肾病、移植肾淋巴瘤、钙调磷酸酶抑制剂(CNI)毒性和草酸盐肾病等.结论 儿童肾移植术后指征性移植肾穿刺病理以急性排斥反应和新发/复发肾病为主,病理活检对患者病因诊断和及时治疗起重要作用. Objective To analyze the histopathologic features of indicative renal allograft biopsies in pediatric transplant recipients.Methods Histopathologic data of renal allograft biopsies from January 2003 to March 2017 in pediatric transplant recipients were retrospectively analyzed.Results There were 35 pediatric recipients who underwent 43 incidents of allograft biopsies.The most common pathologic findings were acute rejection (11/35,31.4%) and de novo or recurrent nephropathy (9/35,25.7%).Acute rejection comprised acute T cell-mediated rejection (8/11,72.7%) and acute antibody-mediated rejection (3/11,27.3%).De novo or recurrent allograft nephropathy comprised IgA nephropathy (5/9,55.6%),focal segmental glomerulosclerosis (2/9,22.2%) and hemolytic uremic syndrome (1/9,11.1%).The other pathologic findings included interstitial nephritis (4/35,11.4%),BK virus associated nephropathy,renal allograft lymphoma,calcineurin inhibitor nephrotoxicity and oxalate nephropathy,etc.Conclusion The main causes of indicative renal allograft biopsies in pediatric recipients are acute rejection and de novo or recurrentallograft nephropathy.Renal allograft biopsy provides instructive values for the diagnosis and precision treatment of post-transplant morbidities.
