Adverse pregnancy outcome in low PAPP-A levels: First trimester screening hospital based study

Abstract

To assess the adverse pregnancy outcome in Low Pregnancy Associated Plasma Protein -A (PAPP-A) levels in serum.This is a prospective cohort study, which included 2150 pregnant women who attended the antenatal clinic of Obstetrics and Gynecology in the Lok Nayak Hospital, New Delhi, India. Blood samples were collected by the venipuncture method for First trimester screening to assess free β-hCG and PAPP-A concentrations were measured by Auto DELFIA (Perkin Elmer, Turku, Finland).In this study a total of 210 women who have the low PAPP-A value less than 0.4 MoM were under the closer surveillance for serious pregnancy outcome. 33(15.6%) women had pre-eclempsia, 27 (12.9%) cases showed intra-utrine growth retardation (IUGR), 6 (3.0%) cases have intra-utrine death. 48 (22.8%) women have pregnancy induced hypertension, and 96(45.6%) cases have other pregnancy related complication. Low PAPP-A levels gives an indication of adverse pregnancy outcome in the early gestation age during the first trimester.
