The Association between Second-Trimester Maternal Serum Alpha-Fetoprotein in 14-22 Weeks and Adverse Pregnancy Outcome
,
Abstract
Aim of this study is to determine the risk of adverse pregnancy outcome by maternal serum alphafetoprotein (MSAFP) level. We followed 295 pregnant women from MSAFP screening in the 14th to 22th week of gestation until the end of pregnancy and information on pregnancy outcome have been recorded in questionnaires. Of 295 pregnant women, 270 had term labor and 25 had preterm labor. The frequencies of pregnancy outcomes were as following: 3 (1.01%) stillbirths, 25(8.47%) preterm labor, and 10 (3.4%) preterm rupture of membranous (PROM), 15 (5.1%) pre-eclampsia, 23 (7.8%) oligohydramnious, and 1 (0.33%) miscarriage. The mean of preterm labor was significantly associated with the higher level of MSAFP (P =0.021). The mean was 55.1 ng/cc in preterm labor and 41.1 ng/cc in term labor. Also, second trimester MSAFP levels were higher in women with pre-eclampsia (P <0.001). The significant association was found between higher level of MSAFP with oligohydramnious (P <0.001) and low birth weight (P <0.001). Pregnancies with an elevated MSAFP level are associated with adverse obstetric outcomes and need more prenatal care.
