妊娠糖尿病血清瘦素水平与胰岛素抵抗的相关性

目的探讨妊娠糖尿病患者胰岛素抵抗与血清瘦素水平的关系。方法对就诊的妊娠妇女88例进行产前检查,符合标准的妊娠糖尿病43例（GDM）设为研究组,未诊断GDM的45例设立对照组。检测空腹血清瘦素、胰岛素、血脂水平、激素、空腹及餐后2h血糖检测,同时计算稳态模型胰岛素抵抗指数（HOMA-IR）。结果 GDM组患者的血糖、胰岛素均明显高于对照组;其HOMA-IR亦高于对照组;GDM组患者的血清瘦素为（8.22±1.87）ng/ml,明显的高于对照组的（1.15±0.37）ng/ml,两组具有统计学意义（t=2.10,P〈0.05）;GDM组患者其雌激素（21.7±5.5ng/ml）、孕激素（199.9±30.7）ng/ml和血PRL（5.5±1.1）IU/ml较NGT组孕妇明显的增高（P〈0.05）;经多元逐步回归分析显示,FINS、HOMA-IR与血清瘦素水平密切相关;瘦素在不同孕周中的表现为瘦素随着孕周的进行呈现上升趋势。结论在GDM患者中除了正常的生理性IR以外,还存在着病理性的IR过程,而其中GDM患者血中的瘦素与胰岛素之间存在拮抗作用,因此未来给予外源性拮抗瘦素作用药物将可能成为治疗GDM提供一条新的途径。

Correlation between serum leptin levels and insulin resistance in gestational diabetes

Objective To investigate the relationship between serum leptin levels and insulin resistance in gestational diabetes.Methods The study enrolled forty-three patients with newly diagnosed gestational diabetes(GDM) and forty-five healthy pregnancy women control subjects.Fasting serum leptin levels were measured along with insulin,fasting glucose,2-Hr postprandial glucose and lipids.The lipids include total cholesterol,triglycerides,HDL-cholesterol and LDL-cholesterol.Insulin resistance was investigated by the ...
