近日,发表于Annals of Internal Medicine的一项随机对照试验表明,长期使用匹格列酮治疗同时伴有脂肪性肝病和糖尿病前期或2型糖尿病的患者来说是安全有效的。

非酒精性脂肪性肝病是一个日益严重的全球性公共健康问题,是导致发达国家慢性肝病发生的最常见病因。其患病率随着肥胖和2型糖尿病的急剧增加而增加,据估计,超30%的美国成年人患有非酒精性脂肪性肝病。大部分患者患有单纯性脂肪变性以及一些相关的良性临床表现,但是一小部分会进展为非酒精性脂肪性肝炎,从而或可发展为肝硬化和肝癌,并增加心血管疾病和慢性肾脏疾病的发生风险。

吡格列酮是一种用于治疗胰岛素抵抗和脂肪组织功能障碍的药物,可阻止糖尿病前期向2型糖尿病进展,但是对于其长期使用的安全性仍存在争议。

该研究共纳入101名非酒精性脂肪性肝炎伴糖尿病前期(49%)或2型糖尿病(51%)的患者。将其随机分配到匹格列酮治疗组和安慰剂治疗组,给药超过18个月,同时辅以低热量减肥饮食。0,18和36个月时进行肝活检。对治疗18个月后未解决的非酒精性脂肪性肝炎患者则继续服用吡格列酮或重新开始服用18个月。

最终,约83名(82%)患者完成了第一个18个月的治疗,69名完成了开放标签阶段(36个月)。第18个月时,与安慰剂治疗组相比,匹格列酮治疗组患者更可能达到主要终点——非酒精性脂肪性肝病活动评分减少至少两个点,且没有恶化为肝纤维化(58% V 17%;P<0.001)。该疾病活动评分的各部分——脂肪变性、炎症以及气球样变,均表现出显著改善。

在纤维化改善方面,匹格列酮治疗组与安慰剂治疗组之间差异并无统计学意义(39% V 25%)。但是,与安慰剂治疗组相比,匹格列酮治疗组患者的平均纤维化评分和纤维化进展率均有轻微的降低(12% V 28%,P = 0.039)。

延长治疗至36个月并没有较治疗18个月出现任何额外的改善。尽管匹格列酮治疗组患者体重增加更大,但是两组不良事件的总体率并没有显著的差异。

在一伴随篇社论中,来自塞维利亚大学的Vilar-Gomez,和来自西澳大利亚大学的Leon Adams写道,“我们认为,对于同时伴有非酒精性脂肪性肝炎和糖尿病的患者来说,医生应考虑吡格列酮的使用,但是目前吡格列酮广泛使用的主要障碍在于其安全性。

因此,对于风险最大(同时伴有非酒精性脂肪性肝炎和纤维化)的患者应考虑吡格列酮的使用,且应考虑避免常见的体重增加风险以及骨折和心脏衰竭的罕见风险。”
