OBJECTIVE:To observe the effects of insulin glargine in type 2 diabetes mellitus patients with poor glucose con-trol by rosiglitazone and metformin. METHODS:A total of 90 patients with type 2 diabetes mellitus with poor glucose control by rosiglitazone and metformin admitted to our hospital from Aug. 2013 to Dec. 2015 were divided into control group and observation group according to random number table,with 45 cases in each group. Control group was given Acarbose tablets 50 mg orally be-fore meal,tid,with maximal dose of 300 mg/d. Observation group was given Insulin glargine injection subcutaneously,qd,with initial dose of 0.15 u/kg,adjusted according to blood glucose monitoring,with maximal dose of 40 u/d. Both group were treated for 24 weeks. The levels of fasting blood glucose,2 h postprandial blood glucose,HbA1c,fasting C peptide and 2 h postprandial C peptide were compared between 2 groups before and after treatment. The time of blood glucose reaching target and the occur-rence of adverse events were recorded,and the incidence of adverse events was calculated. RESULTS:Before treatment,there was no statistical significance in above indexes between 2 groups(P>0.05). After treatment,The levels of fasting blood glucose and 2 h postprandial blood glucose in 2 groups were significantly lower than before treatment,and the levels of fasting C peptide,2 h postprandial C peptide and HbA1c were significantly higher than before treatment;except for fasting blood glucose,above indexes of observation group were significantly better than those of control group,with statistical significance (P0.05).治疗后,两组患者的空腹血糖和餐后2 h血糖水平均显著低于治疗前,空腹C肽、餐后2 hC肽和HbA1c水平均显著高于治疗前;且除空腹血糖外,观察组患者上述指标均显著优于对照组,差异均有统计学意义(P<0.05).观察组患者血糖达标时间显著短于对照组,夜间低血糖、严重低血糖、水肿、胃肠道反应以及总不良事件的发生率均显著低于对照组,差异均有统计学意义(P<0.05).结论:甘精胰岛素用于治疗罗格列酮与二甲双胍降糖效果不佳的2型糖尿病患者,能有效降低其血糖和HbA1c水平,改善胰岛功能,且安全性较高.
