摘要

目的探讨在二甲双胍基础上联合使用二肽基肽酶 4 和钠-葡萄糖共转运体 2 抑制剂对进餐后激素和代谢反应的互补作用。研究设计与方法 45 名 2 型糖尿病患者（年龄 58 ± 8 岁；HbA1c 58 ± 6 mmol/mol；体重指数 30.7 ± 3.2 kg/m2）进行了基线评估，并在服用 5 毫克沙格列汀 (SAXA)、10 毫克达帕格列净 (DAPA) 或 5 毫克沙格列汀加 10 毫克达帕格列净 (SAXA+DAPA) 3 天和 28 天后进行了双踪葡萄糖混合餐耐受试验 (MMTT)，以评估葡萄糖代谢、胰岛素分泌和敏感性。结果在第 3 天，SAXA+DAPA 的空腹和平均 MMTT 葡萄糖水平（-31.1 ± 1.6 和 -91.5 ± 12.4 mg/dL）低于 SAXA（-7.1 ± 2.1 和 -53 ± 10.5 mg/dL）或 DAPA（分别为 -17.0 ± 1.1 和 -42.6 ± 10.0 mg/dL；P < 0.001）。胰岛素分泌率（SAXA+DAPA +75%；SAXA +11%；DAPA 3%）和胰岛素敏感性（分别为 +2.2±1.7、+0.4±0.7 和 +0.4±0.4 mg ⋅ kg-1⋅ min-1）在 SAXA+DAPA 的作用下有所改善（P &;lt;0.007）。SAXA+DAPA的平均胰高血糖素样肽1（GLP-1）高于SAXA或DAPA。DAPA 和 SAXA+DAPA 会增加空腹胰高血糖素，而 SAXA 不会。SAXA+DAPA 和 DAPA 会增加空腹内源性葡萄糖生成量（EGP）。在 MMTT 期间，SAXA+DAPA 的 EGP 抑制率更高（48%）（与 SAXA 44%; P = 0.02 或 DAPA 34%; P = 0.2 相比）。SAXA+DAPA的葡萄糖代谢清除率（MCRglu）增加得更多。第 4 周时，SAXA+DAPA 组的胰岛素分泌率、β 细胞葡萄糖敏感性和胰岛素敏感性进一步提高（P = 0.02），而 GLP-1、胰高血糖素、空腹或 MMTT EGP 或 MCRglu 均无额外变化。结论 SAXA+DAPA 的血糖控制效果优于 DAPA 或 SAXA，β 细胞功能、胰岛素敏感性、GLP-1 利用率和葡萄糖清除率均有所改善。

β-Cell Function, Incretin Effect, and Glucose Kinetics in Response to a Mixed Meal in Patients With Type 2 Diabetes Treated With Dapagliflozin Plus Saxagliptin

OBJECTIVE To explore the complementary effects of a combination of dipeptidyl peptidase 4 and sodium–glucose cotransporter 2 inhibitors added to metformin on hormonal and metabolic responses to meal ingestion. RESEARCH DESIGN AND METHODS Forty-five patients (age 58 ± 8 years; HbA1c 58 ± 6 mmol/mol; BMI 30.7 ± 3.2 kg/m2) with type 2 diabetes uncontrolled with metformin were evaluated at baseline and 3 and 28 days after 5 mg saxagliptin (SAXA), 10 mg dapagliflozin (DAPA), or 5 mg saxagliptin plus 10 mg dapagliflozin (SAXA+DAPA) using a mixed-meal tolerance test (MMTT) spiked with dual-tracer glucose to assess glucose metabolism, insulin secretion, and sensitivity. RESULTS At day 3, fasting and mean MMTT glucose levels were lower with SAXA+DAPA (−31.1 ± 1.6 and −91.5 ± 12.4 mg/dL) than with SAXA (−7.1 ± 2.1 and −53 ± 10.5 mg/dL) or DAPA (−17.0 ± 1.1 and −42.6 ± 10.0 mg/dL, respectively; P < 0.001). Insulin secretion rate (SAXA+DAPA +75%; SAXA +11%; DAPA 3%) and insulin sensitivity (+2.2 ± 1.7, +0.4 ± 0.7, and +0.4 ± 0.4 mg ⋅ kg−1⋅ min−1, respectively) improved with SAXA+DAPA (P < 0.007). Mean glucagon-like peptide 1 (GLP-1) was higher with SAXA+DAPA than with SAXA or DAPA. Fasting glucagon increased with DAPA and SAXA+DAPA but not with SAXA. Fasting endogenous glucose production (EGP) increased with SAXA+DAPA and DAPA. During MMTT, EGP suppression was greater (48%) with SAXA+DAPA (vs. SAXA 44%; P = 0.02 or DAPA 34%; P = 0.2). Metabolic clearance rate of glucose (MCRglu) increased more with SAXA+DAPA. At week 4, insulin secretion rate, β-cell glucose sensitivity, and insulin sensitivity had further increased in the SAXA+DAPA group (P = 0.02), with no additional changes in GLP-1, glucagon, fasting or MMTT EGP, or MCRglu. CONCLUSIONS SAXA+DAPA provided superior glycemic control compared with DAPA or SAXA, with improved β-cell function, insulin sensitivity, GLP-1 availability, and glucose clearance.
