摘  要:目的总结甲基丙二酸血症(methylmalonic acidemia,MMA)的肝移植围术期临床特点和管理经验。方法回顾性分析2014年12月至2019年12月13例肝移植术后MMA患者的围术期临床特征、实验室检查结果、尿MMA变化及治疗情况。结果纳入的13例患者均被诊断为单纯型MMA,5例患者接受了公民逝世后器官捐献的肝脏移植(deceased donor liver transplantation,DDLT),8例接受了活体肝移植(living donor liver transplantation,LDLT)。肝移植术后早期MMA患儿代谢情况有所波动,碱剩余及HCO3-水平在术后3 d及2周较术前逐渐好转。肝移植术后C3、C3/C2水平较术前明显下降,术后尿MMA水平较术前下降了82.41%(P<0.01),但仍高于正常值上限。在肝移植围术期,通过制定个性化免疫抑制方案,2例肝移植术前存在肾功能不全患者的肾脏功能逐渐恢复并趋于稳定。2例患儿出现神经系统的影像学改变。所有患儿至今存活。中位随访时间为63.6(30~100.8)个月。结论肝移植是MMA患者代谢危象的有效治疗方法,在围术期需严密监测血气结果,避免酸中毒发生,酌情给予碳酸氢钠纠正酸中毒,MMA合并肾功能不全的患者需制定个性化的免疫抑制方案。Objective To summarize the perioperative characteristics and management of isolated methylmalonic acidemia after liver transplantation.Methods A total of 13 MMA patients undergoing LT were enrolled in our study from December 2014 to December 2019,the clinical characteristics,laboratory datas,chronological changes in urine MMA levels and treatment were analyzed retrospectively.Results All the 13 cases were diagnosed with isolated MMA.Five cases were received deceased donor liver transplantation(DDLT),and eight cases received living donor liver transplantation(LDLT).Within the early days after LT surgery,metabolic condition fluctuated.The mean base excess of blood value and plasma bicarbonate(HCO3-)restored to normal gradually within two weeks after LT.Our study also indicated that propionyl carnitine(C3)and C3/C2 level showed marked reduction after LT.The mean urine MMA was reduced by 82.41%compared with the urine level of MMA before liver transplantation(P<0.01),but remained>63 folds higher than upper limit of normal.The two patients with renal insufficiency before LT maintained stable by adjusting the immunosuppressive regimen during the observation period.Imaging changes of the nervous system were observed in 2 cases.All patients survive to date.Conclusion LT is regarded as an effective treatment to prevent metabolic crisis of MMA,we should give closely monitor the blood gas analysis to avoid the acidosis episodes by implementing sodium bicarbonate.Personalized immunosuppressive regimen should be developed for those MMA patients with kidney dysfunction.
