Clin Epidemiol:非酒精性脂肪肝的临床过程:对疾病严重性、进展和结果的评估

2017-12-27 MedSci MedSci原创

在中位随访2.3年的过程中,大约有17%的患者发生疾病进展或死亡。存在T2DM的NALFD患者发生疾病进展的风险约为非T2DM的NALFD患者的两倍,死亡风险随着疾病阶段的增加而增加。早期诊断和监测疾病进展,特别是对T2DM患者,是值得的。

研究背景:本研究旨在确定非酒精性脂肪性肝病(NAFLD)患者的特征和初始病情严重程度,以及评估疾病进展的发病率和危险因素。

研究方法:本研究为一项回顾性研究。从Geisinger健康系统电子病历资料中筛选,2004年至2015年之间,年龄≥18岁无酗酒或其他肝病(如乙型肝炎)病史的患者。最初的疾病阶段分为非复杂的NAFLD、晚期纤维化、肝硬化、肝细胞癌(HCC)和肝移植。疾病进展被定义为肝纤维化分期进展或死亡,并通过Kaplan-Meier图和多态模型进行分析。

研究结果:在NAFLD队列中(N=18,754),61.5的患者为女性,39.0%的患者存在2型糖尿病(T2DM),平均身体质量指数(BMI)为38.2±10.2 kg/m2。最初时,69.9%的患者疾病病情为非复杂NAFLD,11.7%的患者为严重肝纤维化患者,17.8%的患者为肝硬化患者。在评估疾病进展的18,718例患者中,中位随访时间为842天,17.3%的患者疾病发生进展(11.0%的患者发生肝纤维化分期进展,6.3%的患者发生死亡,且并没有发生明显的肝纤维化分期进展)。存在2型糖尿病的患者,未存在2型糖尿病的患者,发生疾病进展的比率分别为24.7%和12.3%。非复杂NAFLD患者,1年死亡率为0.5%;肝癌患者,1年死亡率为22.7%。

研究结论:在中位随访2.3年的过程中,大约有17%的患者发生疾病进展或死亡。存在T2DM的NALFD患者发生疾病进展的风险约为非T2DM的NALFD患者的两倍,死亡风险随着疾病阶段的增加而增加。早期诊断和监测疾病进展,特别是对T2DM患者,是值得的。
