Abstract:
Objective To evaluate clinical features,insulin sensitivity,and serum adipocytokines levels in pregnant women with different glucose tolerance status and to investigate the possible serum predictive biomarkers of gestational diabetes mellitus (GDM).Methods We included 74 pregnant women with positive results of 50 g glucose challenge test (GCT),who received regular obstetrical follow-up in Peking Union Medical College Hospital from January 2009 to June 2012.A further 100 g oral glucose tolerance test was performed in 24-28 gestational weeks,based on which the 74 pregnant women were divided into GDM group (n =25),impaired glucose tolerance (IGT) group (n =25) and normal glucose tolerance (NGT) group (n =24).The clinical data were recorded in detail.Serum fibroblast growth factor (FGF)-19,FGF-21,visceral adiposespecific serine protease inhibitor (vaspin),leptin,insulin-like growth factor binding protein-1 (IGFBP-1),and adiponectin levels of the 3 groups were measured by enzyme-linked immunosorbent assay (ELISA) and compared.The associations of these adipocytokines with the patients' baseline data and metabolic indexes were analyzed.Results The blood glucose after GCT and glycosylated hemoglobin A1c in the GDM group were significantly higher than those in the NGT group [(9.21 ±0.75) mmol/L vs.(8.52 ±0.50) mmol/L,P ＜0.05;(5.39 ± 0.34) ％ vs.(5.18 ± 0.20) ％,P ＜ 0.05],but not significantly different from those in the IGT group [(9.14 ± 0.64) mmol/L,P ＞ 0.05;(5.28 ± 0.28) ％,P ＞ 0.05].Age,systolic blood pressure and diastolic blood pressure in the first trimester,pre-gestational body mass index (BMI),increment of BMI during pregnancy,serum total cholesterol,triglyceride,high-density lipoprotein cholesterol,low-density lipoprotein cholesterol,and C-reactive protein levels in the three groups showed no significant differences (all P ＞0.05).From the NGT group to the IGT group to the GDM group,the area under curve of blood glucose (AUCBG) [(19.84±1.95),(23.20±1.51),(26.58±2.02) mmol/(L · h)] and AUC of insulin (AUCINS) [(1.84± 0.91) ×103,(1.85 ±1.15) ×103,(2.49 ±1.36) ×103 pmol/(L · h)] both gradually increased.Compared with the NGT group,the GDM group had significantly higher HOMA-IR [3.0 (1.5,5.2) vs.2.5 (1.5,3.4),P ＜0.05] significantly lower HOMA-β [230.5 (144.6,311.6) vs.235.6 (168.1,350.0),P ＜ 0.05].Among the GDM,the IGT,and the NGT groups,there were no significant differences in serum FGF-19 [(284.42±78.16),(268.17 ±72.97),(283.86 ±79.74) ng/L],FGF-21 [(798.16±273.57),(882.43 ±322.17),(842.75 ±343.01) ng/L],vaspin [(22.36 ±7.27),(23.53 ±7.90),(22.63±9.11) μag/L],leptin [(5.51 ± 1.44),(5.58 ± 1.58),(5.48 ± 1.47) μg/L],adiponectin [(798.85 ± 255.14),(863.44 ± 252.18),(828.36 ± 249.32) μg/L] and IGFBP-1 [(40.44 ± 16.41),(49.57±12.60),(43.80±16.58) μg/L] levels (all P＞0.05).Conclusions There are no significant differences of a variety of adipocytokines in pregnant women with different glucose tolerance status,and no effective serum predictors of GDM are found.The effect of adipocytokines in the pathogenesis of GDM remains to be further investigated.
