非生物型人工肝技术应用于儿童肝移植术后移植物肝脏失功能2例

Non-biological artificial liver technology in the treatment of early liver allograft dysfunction in 2 children with liver transplantation

对上海交通大学医学院附属上海儿童医学中心儿科重症监护病房收治的2例早期移植物肝脏失功能患儿临床资料进行回顾性分析,探讨血浆置换联合连续性静脉-静脉血液透析滤过替代疗法在此类患儿中的临床意义。例1原发病为胆道闭锁,例2原发病为尼曼匹克病,2例患儿肝移植术后均出现移植物肝脏失功能和多脏器功能不全。术后2 d启动间断血浆置换联合连续性静脉-静脉血液透析滤过方案,经1周干预后2例患儿均成功逆转了急性期的多脏器功能不全,肝功能得到恢复。儿童肝移植术后可尝试非生物型人工肝技术,这一技术有助于肝功能的恢复并可改善继发的多脏器功能不全。

The clinical data of 2 children with early graft liver dysfunction(EAD)admitted to the Pediatric Intensive Care Unit,Shanghai Children′s Medical Center,Shanghai Jiaotong University School of Medicine were retrospectively analyzed to discussed the therapeutic significance of non-biological artificial liver technology,such as intermittent plasma exchange(PE)combined with continuous veno-venous hemodiafiltration(CVVHDF)in children with EAD.Case 1 was suffering from biliary atresia,and case 2 was suffering from Niemann-Pick disease.Graft liver dysfunction and multiple organ dysfunction occurred in 2 children after liver transplantation.PE and CVVHDF were initiated early in the first two days after liver transplantation.After one-week therapy with intermittent PE plus CVVHDF,acute multiple organ dysfunction were reversed with liver function remarkably improved in the 2 cases.Therefore non-biological artificial liver technique can be tried after liver transplantation in children.This technique contributes to the recovery of liver function and can improve the secondary multi-organ insufficiency.
