目的基于网状Meta分析(NMA)方法,系统评价二甲双胍缓释片(Ⅳ)治疗2型糖尿病(T2DM)的相对疗效与安全性。
方法检索美国国立医学图书馆数据库(PubMed)、荷兰医学文摘数据库(Embase)、循证医学数据库(the Cochrane Library)、中国期刊全文数据库(CNKI)、万方数据库、美国食品药品监督管理局评审报告,收集比较二甲双胍缓释片(Ⅳ)和其他二甲双胍缓释片治疗T2DM患者疗效及安全性的随机对照试验(RCT),检索时限均为建库至2023年6月30日。按照纳排标准进行文献筛选,并从文献中提取资料和评价被纳入研究的偏倚风险后,采用WinBUGS 14.0软件进行NMA。
结果共纳入7项RCT,3 769例患者。NMA分析结果显示,二甲双胍缓释片(Ⅳ)相比于另外3种二甲双胍缓释片及二甲双胍速释片在降低糖化血红蛋白(HbA 1c)更具优势[二甲双胍缓释片(Ⅳ)相比于二甲双胍缓释片(Ⅲ)组MD=-0.62%,95%CI -0.88%~-0.36%, P<0.05;二甲双胍缓释片(Ⅳ)相比于二甲双胍缓释片(Ⅱ)组MD=-0.46%,95%CI -0.74%~-0.19%, P<0.05;二甲双胍缓释片(Ⅳ)相比于二甲双胍缓释片组MD=-0.39%,95%CI -0.65%~-0.14%, P<0.05;二甲双胍缓释片(Ⅳ)相比于二甲双胍速释片组MD=-0.36%,95%CI -0.59%~-0.13%, P<0.05]。在控制基线HbA 1c、体重指数(BMI)及随访时长后这种优势仍然存在。在降低空腹血糖(FPG)方面,二甲双胍缓释片(Ⅳ)相比于二甲双胍缓释片(Ⅲ)更具优势(MD=-0.66 mmol/L,95%CI -1.31~-0.01 mmol/L)。安全性方面,二甲双胍缓释片(Ⅳ)与前三代二甲双胍缓释片及速释片相比患者因不良反应停药率(WADE)及胃肠反应差异均无统计学意义( P>0.05)。
结论二甲双胍缓释片(Ⅳ)相对于前三代二甲双胍缓释片及二甲双胍速释片对T2DM具有更好的降糖作用,WADE无明显差异,二甲双胍缓释片(Ⅳ)有较为优异的降糖疗效和安全性。
ObjectiveTo systematically review the efficacy and safety of metformin extended-release (ER) (Ⅳ) in the treatment of type 2 diabetes mellitus (T2DM) via network meta-analysis (NMA).
MethodsDatabases including PubMed, Embase, the Cochrane Library, China national knowledge infrastructure (CNKI), Wanfang Data and Food and Drug Administration (FDA) were searched to identify randomized controlled trial (RCT) from inception to 30 June 2023. After a thorough review of the literature based on exclusion criteria, data extraction, and assessment of study bias, WinBUGS 14.0 software was used to conduct the network meta-analysis (NMA).
ResultsA total of 7 RCT with 3 769 patients with T2DM were included. The results of NMA showed that, metformin ER(Ⅳ) group had a significant reduction in glycated hemoglobin (HbA 1c), when compared with metformin ER (Ⅲ) group (MD=-0.62%, 95%CI -0.88%--0.36%, P<0.05), metformin ER (Ⅱ) group (MD=-0.46%, 95%CI -0.74%--0.19%, P<0.05), metformin ER group (MD=-0.39%, 95%CI -0.65%--0.14%, P<0.05) and metformin immediate release (IR) group (MD=-0.36%, 95%CI -0.59%--0.13%, P<0.05). In meta-regression analysis, metformin ER (Ⅳ) group also had an advantage in reducing HbA 1c compared with the other four groups after controlling for baseline of HbA 1c, body mass index (BMI) and follow-up time. Compared with metformin ER (Ⅲ) group, metformin ER (IV) group is more effective in reducing fasting plasma glucose (FPG) (MD=-0.66 mmol/L, 95%CI -1.31--0.01). In terms of safety, compared with other groups, metformin ER (Ⅳ) group had no significantly different in the withdrawal due to adverse event (WADE) and gastrointestinal adverse events ( P>0.05).
ConclusionMetformin ER (Ⅳ) might have beneficial effects on glycemic control in T2DM and has similar performance in WADE to the previous three generations of metformin ER and metformin IR.
