摘要

导言:有妊娠糖尿病(GDM)病史的妇女患2型糖尿病的风险很高,但其病理生理学的确切机制仍不清楚。在前瞻性 PPSDiab(2 型糖尿病的预测、预防和亚分类)研究中,我们调查了胰高血糖素样肽-1(GLP-1)对口服葡萄糖的反应与曾患 GDM 妇女血糖控制参数的关联:研究设计:在口服葡萄糖耐量试验(OGTT)期间,对既往患过 GDM 的妇女(129 人)和孕期糖耐量正常的妇女(67 人)(对照组)的葡萄糖代谢参数和 GLP-1 分泌进行了分析。评估了第一和第二阶段胰岛素和GLP-1分泌与血浆葡萄糖(PG)水平的关系,并对曾患过GDM且基线血糖状态正常的妇女(58人)进行了为期5年的随访,分析了糖尿病前期的发展情况:结果:GDM 后妇女与对照组之间的 PG 和胰岛素曲线下面积(OGTT 0-120 分钟期间的 AUC)有显著差异,但 GLP-1 无显著差异。然而,与 PG 和血浆胰岛素相比,曾患 GDM 的妇女在 OGTT 的第二阶段对 GLP-1 的反应明显降低。随访 5 年后,19.0% 的 GDM 后妇女在基线访问时血糖状态正常,但后来出现了糖代谢异常。总、第一阶段和第二阶段的AUC GLP-1/PG和GLP-1/胰岛素比率与糖耐量异常的发生无关:结论:既往患过 GDM 的妇女的 GLP-1 反应与 PG 和胰岛素浓度相关性降低,表明葡萄糖代谢早期出现异常。然而,对口服葡萄糖的 GLP-1 反应的改变并不能预测 GDM 后最初 5 年中糖尿病前期和 2 型糖尿病的进展。

Association of GLP-1 secretion with parameters of glycemic control in women after gestational diabetes mellitus.

Introduction: Women with a history of gestational diabetes mellitus (GDM) are at high risk of developing type 2 diabetes, while the exact mechanisms underlying its pathophysiology are still unclear. We investigated the association of glucagon-like peptide-1 (GLP-1) response to oral glucose with parameters of glycemic control in women with previous GDM in the prospective PPSDiab (Prediction, Prevention, and Subclassification of Type 2 Diabetes) study.

Research design and methods: Glucose metabolism parameters and GLP-1 secretion were analyzed during oral glucose tolerance test (OGTT) in women with previous GDM (n=129) and women with a history of normal glucose tolerance (n=67) during pregnancy (controls). First- and second-phase insulin and GLP-1 secretion in relation to plasma glucose (PG) levels were assessed, and development of pre-diabetes was analyzed after 5-year follow-up among women with previous GDM and a normal glycemic state at baseline (n=58).

Results: The area under the curve (AUC during the OGTT 0-120 min) of PG and insulin but not GLP-1 differed significantly between post-GDM women and controls. However, women with previous GDM had a significantly decreased GLP-1 response in relation to PG and plasma insulin during the second phase of the OGTT. After a follow-up of 5 years, 19.0% post-GDM women with a normal glycemic state at the baseline visit developed abnormal glucose metabolism. The total, first- and second-phase AUC GLP-1/PG and GLP-1/insulin ratios were not associated with development of abnormal glucose tolerance.

Conclusions: Women with previous GDM showed a reduced GLP-1 response in relation to PG and insulin concentrations indicating early abnormalities in glucose metabolism. However, the altered GLP-1 response to oral glucose did not predict progression to pre-diabetes and type 2 diabetes in the first 5 years after GDM.
