Abstract

Objective: The objective of this study was to compare the levels of Serum Activin A and Inhibin A in Pregnancy induced hypertension, Preeclampsia & Normal Pregnancy

Material and Methods: An analytical, cross-sectional study conducted at Chemical Pathology Laboratory Collaborating with Gynae/Obstetric Department of Pakistan Railway Teaching Hospital, Rawalpindi over the period of one year (18 Sep 2019 to 18 March 2020). The study started after the approval of Ethical Review Committee, Riphah International University Islamabad. The sample size was calculated using WHO sample size calculator. Taking Prevalence of PIH and PE is 8%.3 Non probability convenient sampling technique was used. An overall 100 pregnant women with gestation of 20 – 25 weeks, were included. Patients of UTI, Carcinomas, Diabetes Mellitus and other chronic disorders were not included. The subjects were divided into three groups. Group I PIH: This group included 30 pregnant women of PIH; 20 - 25 weeks of gestation, BP: ≥140/90 mmHg on two separate occasions without proteinuria. Group II PE: This group included 20 pregnant women of preeclampsia; 20 - 25 weeks of gestation, BP: ≥140/90 mmHg on two separate occasions with proteinuria (>0.3 g protein/24 hours Urine). Group III Control Group: This group included 50 pregnant women with gestational age of 20 – 25 weeks without any complication as healthy controls.

Results: It was determined that Serum Activin A and Serum Inhibin A levels were significantly increased in PIH and PE groups as compared to healthy group. Mean of Serum Activin A in PIH, PE and Control group was (251.53+200.23 pg/ml), (466.95 + 237.40 pg/ml) and (43.35 + 85.22 pg/ml) respectively. Similarly Mean and Standard Deviation of Serum Inhibin A levels in PIH, PE and Control group was (194.78 + 173.00 pg/ml), (349.20 + 190.30 pg/ml) and (17.27 + 44.33 pg/ml) respectively. One-way ANOVA and post-hoc Tukey analysis was conducted to compare the mean of Serum Activin A and Serum Inhibin A levels among three different groups i.e Group 1(PIH and PE), Group 2(PIH and Control) and Group 3 (PE and Control). p-value< 0.05 was considered as statistically significant.

Conclusion: It can be concluded that Serum Activin A and Serum Inhibin A can be used as biochemical markers of PIH and PE. Estimation of Serum Activin A and Inhibin A at an early stage can detect PIH and PE early and further prevents their complications such as Eclampsia and HELLP syndrome.

Keywords: Pregnancy induced hypertension (PIH), Pre-eclampsia (PE), HELLP syndrome (H – Hemolysis, EL- Elevated Liver Enzymes, LP – Low platelets count), Serum activin A, Serum inhibin A.
