- Abstract
- ObjectiveTo evaluate the association between orexin-A level and idiopathic polyhydramnios. DesignCase-control study. SettingTertiary-level university hospital. PopulationTen term pregnant women with idiopathic polyhydramnios and, as the control group, 20 pregnant women with normal amniotic fluid levels. MethodsAmniotic fluid level was measured at admission for delivery using enzyme-linked immunosorbent assay. Maternal blood was obtained from a cannulated vein immediately before delivery, and umbilical blood was collected at the time of delivery, before the separation of the placenta. Main outcome measuresMaternal and umbilical levels of orexin-A. ResultsMean umbilical serum orexin-A level was significantly lower than maternal serum orexin-A level. Umbilical serum orexin-A level was positively correlated with maternal serum orexin-A level, but negatively correlated with amniotic fluid index and birthweight. Umbilical serum orexin-A level was lower in the idiopathic polyhydramnios group than in the control group. However, no difference in maternal serum orexin-A level was observed between the two groups. ConclusionsIdiopathic polyhydramnios was associated with decreased umbilical serum orexin-A levels. Our results provide evidence that orexin-A expression may be involved in amniotic fluid regulation, causing polyhydramnios by downregulation.
