Abstract

OBJECTIVE:

To study the relationship among vaginal sialidase, bacterial vaginosis (BV), chorioammionitis and subsequent adverse outcome of pregnancy.

METHODS:

Vaginal sialidase was measured by colorimetry in samples of vaginal discharges from 80 pregnant women with BV (study group) and 60 normal pregnant women at same gestation weeks (control group). Color turning blue means positive of sialidase activity, and no color changing means negative. The diagnosis of chorioammionitis was based on pathological examination.

RESULTS:

Ninety six dot three percent, 3.3% exhibited sialidase activities in study group and control group, respectively. There were significant differences between these two groups (P < 0.001). By measuring vaginal sialidase activity, the sensitivity, specificity, positive and negative predictive value in diagnosing BV were 96.3%, 96.7%, 97.5% and 95.1%, respectively. Chorioammionitis, premature rupture of membranes, premature delivery and puerperal infection in sialidase positive group were significantly higher than the negative group. Sensitivity, specialty of sialidase activity for chorioammionitis were 87.5%, 50.0%, respectively.

CONCLUSION:

Vaginal sialidase activity has strong relation with bacterial vaginosis. Measuring vaginal sialidase activity is a fast, easy, and useful method to diagnose bacterial vaginosis. It also has relation with chorioammionitis and subsequent adverse outcome of pregnancy.
