[Clinical value of determining C-reactive protein in the maternal serum in pregnancies with threatened premature labor].

In this article, because of the importance of subclinical infections for triggering premature labor, we have investigated the maternal serum levels of C-reactive protein (CRP) in 88 pregnancies with comparable gestational ages at the onset of premature birth symptoms. We found certain associations between possible prolongation of gestation by tocolysis and absence or presence of pathologic values of this acute-phase-protein. Positive CRP-values are associated with significantly lowered prolongation of pregnancy by tocolysis and subsequently lowered gestational age at birth. Though there are no correlations to maternal temperature and white blood cell counts, antenatal CTG-results, amniotic fluid properties and parameters of the neonate, we found probable relations to the detection of Ureaplasmas in the vaginal swabs. Once more we point out to possible associations between mycoplasmas and premature birth.
