Abstract

The decidualized endometrium produces secretory proteins of which secretory endometrial protein PP14 is the major product during the first trimester of pregnancy. The protein is secreted into the uterine lumen as well as into the peripheral blood. The purpose of this study was to examine whether decidual function, evaluated by the serum concentration of PP14, was different in women with early pregnancy bleeding compared to normal pregnant women. A reference range for serum PP14 was established on the basis of single samples from 236 normal pregnant women with ultrasonically confirmed gestational age. All the women were delivered of a normal child at term. The study comprised 128 pregnant women admitted because of vaginal bleeding between 6 and 18 weeks gestation. At ultrasonography, intrauterine fetal heart activity was either present or was confirmed at a subsequent examination. No difference was found in the serum level of PP14 compared to that in normal pregnancies, but women with vaginal bleeding and depressed PP14 levels appeared to have a 5-fold higher risk of preterm delivery than women with bleeding and normal PP14 levels.
