Abstract

Background

Platelet dysfunction is one of the serious and common complications associated with pregnancy-induced hypertension (PIH). Nevertheless, the role of platelet dysfunction in the newborns of PIH mothers is unclear. This study aimed to study platelet problems in infants and women affected by PIH.

Methods

A prospective cohort study was conducted on singleton pregnancies who delivered at a gestation age of 32 weeks or more. The women were divided into the PIH group and the normal control group. The blood tests for maternal and neonatal platelet evaluation such as platelet concentration, mean platelet volume (MPV), and clotting time were performed for comparisons between both groups.

Results

A total of 106 cases were recruited for the study (55 cases in the PIH group and 51 cases in the control group). Hematologic studies showed a significant increase in the incidence of thrombocytopenia and platelet dysfunction (increased MPV) in women affected with PIH when compared with those in the control group (p = .028 and p = .001). However, the platelet study in newborns was not significantly different between both groups (p = .680 and p = .265).

Conclusions

This study supports the theory that endothelial cell damage and platelet aggregation as indicated by thrombocytopenia together with increased MPV levels in maternal affected with PIH. Importantly, this study provides new insight into that these problems in mothers with PIH do not occur in their neonatal vessels, as indicated by normal platelet counts and MPV levels.
