Abstract


There is substantial evidence that urogenital infection is one of the major causes of preterm birth, with bacterial vaginosis being one of these infections. Timely diagnosis and treatment of this condition significantly reduce the rate of preterm birth. The aim of this study was to evaluate the method of pH determination of vaginal fluid in women at a risk of preterm birth. A total of 66 women were included in the study. The women were divided into two groups. Group 1 consisted of 30 women, who measured vaginal pH from week 12 and 36 of gestation twice a week using the test рН-Balance (PremiumDiagnostics, Germany). Group 2 comprised 36 women, who did not measure vaginal pH (control group). Abnormal рН (>4,4) were observed in 9 women (30.0 %). Of them, in 8 women a urogenital infection was observed. All patients received etiotropic treatment. pH measuring in women with a history of miscarriage resulted in 4.5-fold reduction of preterm birth (from 30.0 to 6.7 %). In the control group the was no significant reduction in the rate of preterm birth (from 22.2 to 19.4 %).
