Severe alcoholic hepatitis (sAH) is associated with a poor prognosis. There is no proven effective treatment for sAH, which is why early transplantation has been increasingly discussed. Hepatoblastoma-derived C3A cells express anti-inflammatory proteins and growth factors and were tested in an extracorporeal cellular therapy (ELAD) study to establish their effect on survival for subjects with sAH. Adults with sAH, bilirubin ≥8 mg/dL, Maddrey's discriminant function ≥ 32, and Model for End-Stage Liver Disease (MELD) score ≤ 35 were randomized to receive standard of care (SOC) only or 3-5 days of continuous ELAD treatment plus SOC. After a minimum follow-up of 91 days, overall survival (OS) was assessed by using a Kaplan-Meier survival analysis. A total of 203 subjects were enrolled (96 ELAD and 107 SOC) at 40 sites worldwide. Comparison of baseline characteristics showed no significant differences between groups and within subgroups. There was no significant difference in serious adverse events between the 2 groups. In an analysis of the intent-to-treat population, there was no difference in OS (51.0% versus 49.5%). The study failed its primary and secondary end point in a population with sAH and with a MELD ranging from 18 to 35 and no upper age limit. In the prespecified analysis of subjects with MELD < 28 (n = 120), ELAD was associated with a trend toward higher OS at 91 days (68.6% versus 53.6%; P = .08). Regression analysis identified high creatinine and international normalized ratio, but not bilirubin, as the MELD components predicting negative outcomes with ELAD. A new trial investigating a potential benefit of ELAD in younger subjects with sufficient renal function and less severe coagulopathy has been initiated. Liver Transplantation 24 380-393 2018 AASLD.
严重酒精性肝炎(sAH)预后不良。目前尚无针对 sAH 的有效治疗方法,因此越来越多地讨论早期移植。肝癌衍生的 C3A 细胞表达抗炎蛋白和生长因子,并在体外细胞治疗(ELAD)研究中进行了测试,以确定其对 sAH 患者生存的影响。患有 sAH 的成年人,胆红素≥8mg/dL,Maddrey 判别函数≥32,以及终末期肝病模型(MELD)评分≤35,随机接受标准治疗(SOC)或 3-5 天连续 ELAD 治疗加 SOC。在至少 91 天的随访后,使用 Kaplan-Meier 生存分析评估总生存率(OS)。共有 203 名患者在全球 40 个地点入组(96 名 ELAD 和 107 名 SOC)。基线特征比较显示两组之间和亚组内无显著差异。两组严重不良事件无显著差异。在意向治疗人群的分析中,OS 无差异(51.0%对 49.5%)。该研究在 MELD 为 18 至 35 且无年龄上限的 sAH 患者人群中未能达到主要和次要终点。在 MELD<28 的患者(n=120)的预先指定分析中,ELAD 与 91 天时更高的 OS 趋势相关(68.6%对 53.6%;P=0.08)。回归分析确定高肌酐和国际标准化比值,但不是胆红素,是预测 ELAD 不良结果的 MELD 成分。一项新的临床试验已经开始,旨在调查 ELAD 在肾功能充足且凝血障碍较轻的年轻患者中的潜在益处。肝脏移植 24 380-393 2018 AASLD。
