Second trimester maternal dimeric inhibin-A in the multiple-marker screening test for Down's syndrome.
The aim of this study was to evaluate the additional value of dimeric inhibin-A serum concentration in second trimester multiple-marker screening tests for pregnancies affected by Down's syndrome. We anticipated that second trimester maternal serum dimeric inhibin-A concentrations would be altered in pregnancies complicated by fetal Down's syndrome and that dimeric inhibin-A would perform bette...
متن کاملCorrelation of pregnancy outcome with quadruple screening test at second trimester
Background: Abnormal levels of the markers AFP, hCG, and uE3 could be useful in predicting adverse pregnancy outcomes. This study was designed to determine the correlation between second trimester maternal serum markers and adverse pregnancy outcome (APO). Methods: In this historical cohort study, we randomly followed 231 obstetric patients with quadruple screening test in 14-18 weeks of ges...
متن کاملDimeric inhibin A as a marker for Down's syndrome in early pregnancy.
BACKGROUND In screening for Down's syndrome in the second trimester of pregnancy, the concentrations of alpha-fetoprotein, the beta subunit of human chorionic gonadotropin, and intact human chorionic gonadotropin in material serum are widely used markers. We investigated a new marker, dimeric inhibin A, and compared its predictive value with that of the established markers. METHODS Serum samp...
متن کاملIncreased concentrations of prostate-specific antigen in maternal serum from pregnancies affected by fetal Down syndrome.
Down syndrome is one of the most common causes of mental retardation in the industrialized world. Prenatal serum screening to identify mothers at risk of carrying a fetus affected with Down syndrome is presently part of routine obstetrical care. Prostate-specific antigen (PSA) concentration was measured in stored second-trimester maternal serum samples from 19 pregnancies affected with fetal Do...
متن کاملThe Effects of Fetal Gender on Serum Human Chorionic Gonadotropin and Testosterone in Normotensive and Preeclamptic Pregnancies
INTRODUCTION The aim of the present study was to evaluate the effects of fetal sex on serum human chorionic gonadotropin (hCG) and testosterone in normotensive and preeclamptic pregnancies. MATERIALS AND METHODS This is a cross-sectional study and 139 women with singleton pregnancies in the third trimester were studied. Seventy-one pregnancies were uncomplicated; among those were 35 male and ...
