    摘要:

    目的:探讨新诊断2型糖尿病患者日内平均血糖波动幅度(24 h mean amplitude of glycemic excursions,MAGE)影响因素。方法:110例未经治疗的新诊断2型糖尿病患者行连续3 d动态血糖监测(continuous glucose monitoring system,CGMS),计算 MAGE;收集患者基线资料,并检测糖化血红蛋白(hemoglobin A1c,HbA1c)-空腹血糖(fasting blood glucose,FBG)及口服糖耐量试验(OGTT)餐后2 h血糖(postprandial 2 h blood glucose,PBG)-胰岛素-C肽-血脂-肾功能-肝功能。结果:HbA1c是新诊断2型糖尿病MAGE的独立影响因素(P < 0.05),HbA1c<9.9%患者的MAGE显著低于HbA1c≥9.9%患者(5.97 mmol/L vs. 7.43 mmol/L,P < 0.05)。其中当HbA1c<8.5%时,HbA1c主要受PBG影响,但当HbA1c≥9.2%时,则FBG是新诊断2型糖尿病患者HbA1c的独立影响因素(P < 0.001)。FBG<10.84 mmol/L患者的HbA1c显著低于FBG≥10.84 mmol/L患者(9.10% vs. 10.87%,P < 0.001)。结论:HbA1c 是新诊断2型糖尿病患者MAGE的独立影响因素,其中FBG与HbA1c密切相关。

    Abstract:

    Objective:To identify the factors influencing 24 h mean amplitude of glycemic excursion (MAGE) in patients newly diagnosed with type 2 diabetes. Methods:We analyzed the clinical data of 110 patients with type 2 diabetes without treatment. The 24 h MAGE was calculated using 3 d continuous glucose monitoring system (CGMS). Baseline data of patients were collected, and serum hemoglobin A1c(HbA1c), fasting blood glucose(FBG) and postprandial 2 h blood glucose(PBG), insulin and C peptide levels, blood lipid profiles, hepatic and renal functions were measured before treatment. Results:HbA1c was an independent index for 24 h MAGE in newly diagnosed type 2 diabetes mellitus patients (P < 0.05). MAGE in patients with HbA1c < 9.9% was lower than that with HbA1c ≥9.9%(5.97 mmol/L vs. 7.43 mmol/L, P < 0.05). HbA1c in patients with HbA1c < 8.5% was effected mainly by PBG, while FBG was an independent factor influencing HbA1c in newly diagnosed type 2 diabetes mellitus patients with HbA1c≥9.2%(P < 0.001). HbA1c in patients with FBG < 10.84 mmol/L was lower than that with FBG≥10.84 mmol/L (9.10% vs. 10.87%, P < 0.001). Conclusion:HbA1c is an independent factor of MAGE and closely related to FBG in patients newly diagnosed with type 2 diabetes mellitus.
