Abstract
The aim of the present study was to explore the association between pregnancy-induced hypertension (PIH) and insulin resistance (IR). A total of 50 cases of PIH and 50 healthy pregnant women with a similar gestational age were enrolled. The hyperinsulinemic-euglycemic clamp technique was used to evaluate the degree of IR and all 100 subjects were divided into an IR and a non-IR group accordingly. Subsequently, the correlation between the systolic or diastolic blood pressure was assessed; furthermore, a homeostasis model assessment of IR (HOMA-IR), a HOMA of the insulin sensitivity index (HOMA-ISI) and a HOMA of β cell function (HOMA-β%) were performed. Moreover, the effect of IR on PIH was assessed and the protein expression of insulin receptor substrate (IRS)-1, phosphorylated (p)-IRS-1, AKT and p-AKT were detected in the placental plasma by western blot analysis. The results showed that in the PIH group, the p-IRS-1/IRS-1 and p-AKT/AKT ratios were decreased compared with those in the control group. Blood flow parameters, including perfusion index, retinal resistive index and systolic maximum velocity/end-diastolic velocity ratio in the IR group were higher, while time averaged velocity was lower compared with that in the non-IR group. Furthermore, the HOMA-ISI and HOMA-β% were decreased, while the HOMA-IR was increased in the PIH group compared to that in the control group; alongside the blockage of the insulin signaling pathway, these factors may therefore cause PIH. The present study may provide novel therapeutic approaches for PIH.
