Abstract
Background Preeclampsia is one of the hypertensive disorders of pregnancy causing maternal and perinatal mortality and morbidity. The global burden of Pre-eclampsia and eclampsia is 5-10. The prevalence of preeclampsia-complicating pregnancy in India is 7.8. Early prediction of preeclampsia and prophylactic use of aspirin reduces morbidity and mortality.Objectives To study the role of angiogenic factors and biophysical markers to identify women at high risk for developing preterm preeclampsia. To study the diagnostic value of angiogenic factors as predictors of preterm preeclampsia in early pregnancy. To compare the benefits of prophylactic use of 150mg of Aspirin versus 75mg of Aspirin from 11-16 weeks of gestation in reducing the incidences of preterm preeclampsia.Methods It was a two year study conducted at Rajarajeswari Medical College and Hospital. Data for the study was collected from women attending antenatal clinics at 11 weeks 0days to 13weeks 6days after taking informed consent. Screening for preeclampsia was done using biophysical and biochemical tests. Screen-positive women were grouped randomly into Group A and Group B. They were given 7mg and 150mg aspirin and maternal and fetal outcome was analysed.Results In our study 489.6 women were screened positive for preeclampsia. There were no significant differences between the 75mg aspirin group and the 150mg aspirin group with regard to demographic characteristics. Pre-eclampsia occurred in 27.2 of participants in the 75mg aspirin group compared with 4.1 in the 150 mg aspirin group. There was a significant difference in the incidence of PE p0.0293 its severity and the period of gestation at delivery in the two groups. The positive predictive value of the screening method in our study is 12.7 and the negative predictive value is 91.6.Conclusion Our study showed that screening test was beneficial in identifying high-risk cases but the study population was very less. Early screening and use of prophylactic aspirin reduce the development preterm preeclampsia. Aspirin is a safe economical and easily available drug.
