摘要:
目的 探讨2型糖尿病患者采用达格列净联合二甲双胍治疗对稳定控制血糖、减少并发症的临床应用效果,为2型糖尿病的临床治疗提供参考。 方法 选取2021年6月—2023年5月蚌埠医科大学第二附属医院收治的2型糖尿病住院患者80例,其中40例联合给药,即服用达格列净联用二甲双胍,作为实验组;另40例采取单一给药,即仅服用二甲双胍,作为对照组。比较2组治疗效果, 包括治疗前后血糖控制指标[糖化血红蛋白(HbA1c)、空腹血糖(FBG)、空腹C肽、餐后1 h C肽],肾功能指标[血肌酐(Cr)、尿酸(UA)、胱抑素C(CysC)],观察2组患者不良反应发生情况。 结果 实验组患者治疗有效率为92.5%(37/40), 明显高于对照组[75.0%(30/40), P<0.05]。实验组治疗前后HbA1c、空腹血糖、空腹C肽、餐后1 h C肽比较差异有统计学意义(P<0.05);实验组治疗前后肾功能指标(Cr、UA、CysC)比较差异有统计学意义(P<0.05)。实验组不良反应发生率明显低于对照组[17.5%(7/40) vs. 50.0%(20/40), P<0.05]。 结论 达格列净联合二甲双胍治疗2型糖尿病效果较单一使用二甲双胍更好, 可降低患者血糖, 减少不良反应,明显改善患者肾功能。 Abstract:Objective To investigate the clinical effects of treatment with dapagliflozin plus metformin in patients with type 2 diabetes on stable control of blood glucose and reducing complications, to provide a reference for the clinical treatment of type 2 diabetes mellitus. Methods A total of 80 patients with type 2 diabetes admitted to the Second Affiliated Hospital of Bengbu Medical University from June 2021 to May 2023 were selected, of which 40 patients received dagaglizin combined with metformin as the experimental group. Another 40 patients were given a single dose, that is, metformin alone, as a control group. The therapeutic effects of the two groups were compared, and the blood glucose control indexes before and after treatment were as follows: glycated hemoglobin A1c (HbA1c), fasting blood glucose (FBG), fasting C-peptide, and 1 h postprandial C-peptide. Renal function indexes of patients were as folows: serum creatinine (Cr), uric acid (UA), cystatin C (CysC). Clinical therapeutic effects and adverse reactions of patients in two groups were observed after different treatment methods. Results The effective rate of treatment in the test group was 92.5% (37/40), which was significantly higher than that in the control group [75.0% (30/40), P < 0.05]. The results of HbA1c, FBG, fasting C-peptide, and 1 h postprandial C-peptide in the experimental group were significantly different before and after treatment (P < 0.05). The renal function indexes (Cr, UA, CysC) of the experimental group were significantly different before and after treatment (P < 0.05). The incidence of adverse reactions in the experimental group was significantly lower than that in the control group [17.5% (7/40) vs. 50.0% (20/40), P < 0.05]. Conclusion In the treatment of type 2 diabetes mellitus, dagaglizin combined with metformin has a better effect than metformin alone, which can reduce blood glucose and adverse reactions in patients and significantly improve kidney function of patients. -
