Background: Metabolic complications of type 2 diabetes (T2DM), including dyslipidemia, electrolyte imbalance, and oxidative stress, have been shown to be modulated by hypoglycemic agents. Objective: The lipid profile, electrolytes, and oxidative stress indices were evaluated in T2DM. Methods: Fifty T2DM patients on metformin (n = 23), insulin (n = 17), and insulin/metformin (n = 10) and 40 controls were studied. Fasting plasma glucose (FPG), glycated hemoglobin (HbA1c), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), total antioxidant capacity (TAC), total plasma peroxide (TPP), and total calcium (Ca) values were determined colorimetrically, sodium (Na+) and potassium (K+) levels were determined by flame photometry, chloride (Cl–) and bicarbonate (HCO3–) levels were determined by titration, and low-density lipoprotein cholesterol (LDL-C) levels, the atherogenic index of plasma (AIP), and the oxidative stress index (OSI) were determined by calculation. Data were analyzed using t test, analysis of variance, and Pearson’s correlation at p < 0.05. Results: T2DM patients had higher lipid peroxidation (TPP and OSI), atherogenic lipids (higher LDL-C and AIP and lower HDL-C), and lower antioxidants compared to controls (p < 0.05). T2DM patients with poor glycemic control had higher lipid peroxidation (higher TPP) and atherogenic lipids (TG and AIP) compared to those with good control (p < 0.05). Patients with T2DM for >5 years had higher protein glycosylation (higher HBA1c) and TC compared to those with T2DM for <5 years (p < 0.05). The class of hypoglycemic agent has no effect on the levels of all of the biochemical indices studied (p > 0.05). HDL-C correlated negatively with TG (r = –0.347, p = 0.013), LDL-C (r = –0.322, p = 0.018), and AIP (r = –0.714, p = 0.000) in T2DM. Conclusion: Chronic T2DM and poor glycemic control are associated with reduced antioxidants, lipid peroxidation, and atherogenic dyslipidemia. Different hypoglycemic agents exert no differential effects on the metabolic indices of T2DM studied.

2 型糖尿病的降血糖药和氧化应激指数、电解质和心血管危险因素的变化

背景:2 型糖尿病 (T2DM) 的代谢并发症,包括血脂异常、电解质失衡和氧化应激,已被证明受降糖药的调节。目的:评估 T2DM 患者的血脂、电解质和氧化应激指数。方法:研究了 50 名服用二甲双胍(n = 23)、胰岛素(n = 17)和胰岛素/二甲双胍(n = 10)的 T2DM 患者和 40 名对照。空腹血糖 (FPG)、糖化血红蛋白 (HbA1c)、总胆固醇 (TC)、甘油三酯 (TG)、高密度脂蛋白胆固醇 (HDL-C)、总抗氧化能力 (TAC)、总血浆过氧化物 (TPP) 和总钙 (Ca) 值通过比色法确定,钠 (Na+) 和钾 (K+) 水平通过火焰光度法确定,氯化物 (Cl–) 和碳酸氢盐 (HCO3–) 水平通过滴定法确定,通过计算确定低密度脂蛋白胆固醇(LDL-C)水平、血浆致动脉粥样硬化指数(AIP)和氧化应激指数(OSI)。使用 t 检验、方差分析和 P < 0.05 的 Pearson 相关性分析数据。结果:与对照组相比,T2DM 患者具有更高的脂质过氧化(TPP 和 OSI)、致动脉粥样硬化的脂质(更高的 LDL-C 和 AIP 以及更低的 HDL-C)和更低的抗氧化剂(p < 0.05)。与血糖控制良好的患者相比,血糖控制不佳的 T2DM 患者具有更高的脂质过氧化(更高的 TPP)和致动脉粥样硬化的脂质(TG 和 AIP)(p < 0.05)。与 T2DM 患者相比,5 年以上的 T2DM 患者具有更高的蛋白质糖基化(更高的 HBA1c)和 TC(p < 0.05)。降血糖药的类别对所有研究的生化指标的水平没有影响(p > 0.05)。在 T2DM 中,HDL-C 与 TG(r = –0.347,p = 0.013)、LDL-C(r = –0.322,p = 0.018)和 AIP(r = –0.714,p = 0.000)呈负相关。结论:慢性 T2DM 和血糖控制不佳与抗氧化剂减少、脂质过氧化和致动脉粥样硬化的血脂异常有关。不同的降血糖药对所研究的 T2DM 的代谢指标没有不同的影响。
