目的 观察不同疗程吗替麦考酚酯(MMF)治疗激素依赖或激素抵抗成人微小病变肾病(MCD)的疗效和复发率。方法 2011年2月—2013年8月我院收治的25例激素依赖或抵抗成人MCD,随机分为短疗程组12例和长疗程组13例。短疗程组给予MMF联合口服泼尼松治疗6个月,观察12月,长疗程组治疗18个月,前6个月治疗同短疗程组,此后单用小剂量MMF维持,观察两组的疗效及复发率。结果 长疗程组有1例因严重感染在第2月退出研究,其余24例均完成18月的随诊;两组在治疗第6月时尿蛋白定量降低、血浆白蛋白升高,均与治疗前有差异(均P<0.05);与第6月比较,疗程结束时短疗程组尿24小时蛋白定量升高(P<0.05),长疗程组尿24小时定量无明显改变(P>0.05);治疗第6月两组均有9例完全缓解(75%),两组无差异(χ²=0.372,P>0.05);治疗第18月时与第6月比较,短疗程组6例复发(54.54%),长疗程组有2例复发(18.18%),两组复发率比较无差异(χ²=0.076,P>0.05)。结论 MMF能有效诱导缓解成人MCD,小剂量维持治疗可以有效降低复发率。

Objective To observe the efficacy and recurrence rates of mycophenolate mofetil (MMF) on hormone-dependent or steroid-resistant adult minimal change disease (MCD). Methods We retrospectively reviewed the records of adult patients at Shunde district hospital of traditonal Chinese medicine of Foshan for minimal change from February 2011 to August 2013. All patients who were hormone-dependent or steroid-resistant were collected. Twenty-five patients were randomly divided into short or long course group. The patient at short course group was given MMF combined with oral prednisone for 6 months, and the long course group was given for 18 months. Patient demographics, efficacy of medicines and recurrence rates were observed. Results Except one case of the long course group quitting at the second month because of severe infection, the other cases all finished the 18 months of follow up. At the 6 month after therapy with MMF, in both group, the 24h urine protein had lowered significantly (P<0.05) and the serum albumin level had risen remarkably (P<0.05). At the end of the follow up, compared with the 6 month after therapy, the 24 h urine protein of the short course group had increased (P<0.05), while those of the long course group had no obvious difference (P>0.05). At the 6 month after therapy, there were 9 cases achieved complete remission.There was no significant difference between the two groups (χ²=0.372, P>0.05). At the end of the follow up, compared with the 6 month after therapy, there were 6 cases experienced relapse (54.54%) in the short course group and 2 cases of those in the long course group (18.18%), but with no significant difference between them (χ²=0.076, P>0.05). Conclusion MMF can induce the remission of adult MCD efficiently, and its low dose maintenance treatment can decrease recurrence rates.
