二甲双胍可减轻激素副作用!Lancet子刊研究

2020-04-08 卢芳 中国循环杂志

近期发表在Lancet子刊的一项2期临床研究表明,二甲双胍会让糖皮质激素“更完美”,可保留其抗炎作用,而消除其代谢方面的副作用。

近期发表在Lancet子刊的一项2期临床研究表明,二甲双胍会让糖皮质激素“更完美”,可保留其抗炎作用,而消除其代谢方面的副作用。

研究显示,试验持续12周时,在糖皮质激素累积剂量相当的患者中,二甲双胍虽然没有改善内脏与皮下脂肪面积比,但是皮下脂肪较安慰剂组患者明显减少。

此外,服用二甲双胍的激素应用患者中还观察到血糖、血脂以及肝脏和骨骼代谢指标的改善。

还观察到改善纤维蛋白溶解作用、降低炎症水平以及疾病活动期临床标志物水平。

研究还发现,与安慰剂相比,应用二甲双胍的患者肺炎(1 vs 7)、中重度感染(2 vs 11)以及由于不良事件而入院的病例数(1 vs 9)均较少。

不过二甲双胍组患者腹泻更为多见(18 vs 8)。

这项随机、双盲、安慰剂对照、概念验证性2期临床试验,共纳入英国4家医院18~75岁无糖尿病的53例炎症性疾病患者,这些患者均持续接受泼尼松龙治疗(≥20 mg/天,应用≥4周,并在随后的12周内保持≥10 mg/天,或累积剂量当量)。

研究者按年龄和体重指数进行分层并根据计算机产生的表格,将这些患者按1:1比例随机分到二甲双胍组(n=26)或安慰剂组(n=27)。两组分别以递增剂量口服二甲双胍或安慰剂12周:最初5天按850 mg qd,接下来5天按 850 mg bid,之后按850 mg tid。最终二甲双胍组有19例,安慰剂组有21例符合主要结果分析条件。
