title: [Multivariate analysis of the significance of vaginal bacterial colonization in the occurrence of a preterm birth with various risk parameters].
abstract: Using a discriminance analysis we investigated the interactions between parameters of the vaginal flora and subclinical infection regarding preterm birth. The prospective study includes 222 single pregnancies, 114 of them with preterm labour or premature rupture of the membranes (PROM). The analysis includes information of a vaginal/ cervical smear (total number of pathogenic germs, species and groups of pathogenic germs), vaginal pH, maternal white blood cell count (WBC), C-reactive protein (CRP) and temperature. A normal vaginal flora was found in only 19%. Pregnancies with preterm labour have a higher quantity of pathogenic germs, whereas there is no difference of the germ group distribution. Moreover, pregnancies with preterm labour and 2 or 3 pathogenic germs have a higher rate of preterm birth. The discriminance analysis shows that only the affiliation the risk group with preterm labour and the parameters CRP and WBC have a significant selectivity for consequent preterm birth, but not the parameters containing information of the vaginal flora. The same is valid for the group with preterm labour, where only the parameters PROM and WBC are able to select significantly for preterm birth.
