Abstract:
Objective To investigate the relationship between serum leptin(LP) level and glycometabolism in pregnancy with abnormal glucose challenge test(GCT) and the corresponding outcome of pregnancy. Methods Serum LP level,fasting serum insulin(FINS) and fasting blood glucose(FBG) levels were measured by radioimmunoassay in 23 patients with abnormal GCT but normal oral glucose tolerance test(OGTT),20 with impaired glucose tolerance(IGT),20 with gestational diabetes mellitus(GDM)(studied groups above) and 30 normal pregnant women(control group).LP,FINS,FBG, insulin resistance index(HOMA-IR) and ?-cell function index(HOMA-IS) were compared among the groups and the outcomes of pregnancy were observed. Results ①There were significant differences in LP,FINS,FBG,HOMA-IR and HOMA-IS between the studied groups and the control group(P0.05).③There were signi-ficant differences in the gestational weeks of delivery,cesarean section rate and neonatal weight between the studied groups and the control group(P0.05). Conclusion Both insulin secretion and insulin resistance are elevated in pregnancy with abnormal glycometabolism,and are closely correlated to the increased serum level of LP.There existed abnormal glycometabolism in patients with abnormal GCT but normal OGTT,which is correlated to the outcome of pregnancy.
