Abstract
OBJECTIVE: Growth differentiation factor 15 (GDF15) has been demonstrated to increase in diabetes as a protective factor. However, studies assessing relationships between GDF15 levels and gestational diabetes mellitus (GDM) are limited. In this study, we aimed to investigate whether GDF15 levels are related to GDM in Chinese subjects. METHODS: We included 200 GDM patients and 200 matched normal controls in the second trimester as well as 130 GDM patients and 130 matched normal controls in the third trimester. Serum GDF15 levels of all participants were determined using an enzyme-linked immunosorbent assay (ELISA). Then, according to GDF15 levels, we equally divided the participants in the second and third trimesters into four subgroups respectively. The relationships of serum GDF15 levels with glucolipid metabolism indicators were analyzed. RESULTS: In the third trimester, GDF15 levels were significantly higher in the GDM patients than in the normal controls (P < 0.001). Additionally, fasting blood glucose (FBG), 1-h postprandial glucose (1h-PG), 2-h postprandial glucose (2h-PG), hemoglobin A1C (HbA1c) and area under curve of glucose (AUCG) from the 75-g oral glucose tolerance test (OGTT) were positively associated with GDF15 levels (P < 0.05), even after adjusting for age, pregestational BMI, changes of BMI until the third trimester, gestational age, twin and family history of diabetes. Moreover, GDF15 levels were higher in the third trimester than in the second trimester (P < 0.001). No significant relationships were found between GDF15 levels and glucolipid metabolism in the second trimester (P > 0.05). CONCLUSIONS: Serum GDF15 levels were positively correlated with glucose metabolism in the third trimester in Chinese pregnant women.
