JCI:伴有肝硬化的非酒精性脂肪肝增加了晚期纤维化的家族性风险

2017-06-20 MedSci MedSci原创

非酒精性脂肪性肝病和肝硬化(NAFLD-肝硬化)患者一级亲属晚期纤维化的风险是未知的,需要系统地量化。我们的目标是前瞻性评估NAFLD-肝硬化患者一级亲属晚期纤维化的风险。 使用良好表型的家族性队列,我们证明了NAFLD-肝硬化的先证者的一级亲属的晚期纤维化风险增加12倍。 NAFLD-肝硬化患者的一级亲属可以考虑晚期纤维化筛查。

背景:非酒精性脂肪性肝病和肝硬化(NAFLD-肝硬化)患者一级亲属晚期纤维化的风险是未知的,需要系统地量化。我们的目标是前瞻性评估NAFLD-肝硬化患者一级亲属晚期纤维化的风险。

方法:这是对26名NAFLD-肝硬化先证者和39名一级亲属的的前瞻性队列的横断面分析。对照人群包括69名社区住宅双胞胎,同胞或亲代子对(n = 138),其中69人随机确定为无NAFLD,69人为一级亲属。他的主要结果是存在晚期纤维化(3期或4期纤维化)。临床评估NAFLD,并通过MRI质子密度脂肪分数(MRI-PDFF)量化。利用磁共振弹性成像(MRE),通过肝硬度大于3.63 kPa诊断晚期纤维化。

结果:NAFLD-肝硬化患者一级亲属晚期纤维化患病率明显高于对照组(17.9%vs. 1.4%,P = 0.0032)。与对照组相比,NAFLD-肝硬化患者一级亲属晚期纤维化的几率为14.9(95%CI,1.8-126.0,P = 0.0133)。即使在年龄,性别,BMI和糖尿病状态进行多变量调整后,晚期纤维化的风险仍然具有统计学和临床意义(多变量调整优势比12.5; 95%CI,1.1-146.1,P = 0.0438)。

结论:使用良好表型的家族性队列,我们证明了NAFLD-肝硬化的先证者的一级亲属的晚期纤维化风险增加12倍。 NAFLD-肝硬化患者的一级亲属可以考虑晚期纤维化筛查
