ABSTRACT
Hypertensive disorder of pregnancy is a major public health problem worldwide. Pre-eclampsia and its complications are frequent causes for maternal and perinatal mortality and morbidity, particularly in developing countries. In preeclampsia some angiogenic factors like PlGF (Placental growth factor), VEGF (Vascular endothelial growth factor) etc. are assumed to be low in maternal serum. This prospective cohort study was carried out including 134 pregnant women with early gestation (15-20wks) attending the Feto-Maternal Medicine OPD of Bangabandhu Sheikh Mujib Medical University (BSMMU) Hospital, Dhaka, Bangladesh from January 2015 to April 2015. Maternal serum was taken for measurement of PlGF by ELISA technique and values were converted to Multiples of Median (MoM) for their specific gestational age. The subjects were regularly followed up till delivery by measuring blood pressure and testing urine for protein by heat coagulation method. Hypertension was diagnosed if blood pressure found to be more than or equal 140/90mm of Hg and preeclampsia was labeled when proteinuria associated with it. Patients' information was kept in a prepared data sheet. The mean age of the patients was 25.7±5.57 years, mean BMI was 22.42±3.23. The incidence of Hypertensive disorder was 6.72% among them Pregnancy Induced Hypertension (PIH) was 2.98% and Preeclampsia (PE) was 3.9%. The mean age of hypertensive patients was 30.6±5.16 years and BMI was 26.92±1.54. The mean value of PlGF in normotensive women was 1.17±0.67 MoM, PIH patients were 0.66±0.41 MoM and PE patients were 0.65±0.30MoM. The comparison of mean values between Normotensive with PIH (p value 0.023) and Normotensive with PE (p value 0.014) both were found significant. From the current study and also from previous studies we can summarize that the level of PlGF become reduced significantly in pregnant women who will later on develop Hypertensive disorders.
