摘　　要：目的探讨双重血浆置换(DFPP)联合甲泼尼龙(MP)、环磷酰胺(CTX)双冲击疗法治疗儿童重症紫癜性肾炎(HSPN)的临床疗效与安全性。方法将2014年1月至2018年3月收治的60例重症HSPN患儿随机分为观察组和对照组,每组30例。在常规治疗基础上,对照组予MP+CTX双冲击治疗,观察组在对照组基础上联合采用DFPP治疗,共3个疗程。治疗3个疗程后,比较两组24 h尿蛋白定量、尿系列微量蛋白含量、肾功能指标、不良反应及临床疗效。结果治疗3个疗程后,观察组24 h尿蛋白定量、尿白蛋白、尿免疫球蛋白G、尿β2微球蛋白、血肌酐及血尿素氮的下降幅度均显著高于对照组(P < 0.05)。治疗结束后,观察组完全缓解患儿达缓解的时间明显短于对照组(P < 0.05)。两组均未发生出血性膀胱炎、血小板下降、溶血等严重不良反应,两组总体不良反应发生率差异无统计学意义(P > 0.05)。结论 DFPP联合MP+CTX双冲击治疗儿童重症HSPN较单纯MP+CTX冲击治疗能进一步减轻肾脏损害,提高临床疗效,且未加重不良反应的发生。Objective To study the clinical effect and safety of double filtration plasmapheresis (DFPP) combined with double pulse therapy with methylprednisolone (MP) and cyclophosphamide (CTX) in the treatment of children with severe Henoch-Sch?nlein purpura nephritis (HSPN).Methods A total of 60 children with severe HSPN who were admitted to the hospital from January 2014 to March 2018 were enrolled and were randomly divided into an observation group and a control group (n=30 each). In addition to routine treatment, the children in the control group were given MP+CTX pulse therapy. Those in the observation group were given DFPP treatment in addition to the treatment in the control group, with three courses of treatment in total. After three courses of treatment, the two groups were compared in terms of 24-hour urinary protein, urinary microproteins, renal function parameters, adverse reactions, and clinical outcome.Results After three courses of treatment, the observation group had significantly greater reductions in 24-hour urinary protein, urinary albumin, urinary immunoglobulin G, urinary β2-microglobulin, serum creatinine, and blood urea nitrogen than the control group (P < 0.05). After the treatment ended, the observation group had a significantly shorter time to achieve remission than the control group (P < 0.05). No serious adverse reactions, such as hemorrhagic cystitis, thrombocytopenia, and hemolysis, were observed, and there was no significant difference in the overall incidence rate of adverse reactions between the two groups (P > 0.05).Conclusions Compared with MP+CTX pulse therapy alone in the treatment of severe HSPN in children, DFPP combined with MP+CTX pulse therapy can further alleviate renal injury and improve clinical outcome and does not increase the incidence rate of adverse reactions.
