Evidence linking bacterial vaginosis (BV) to chorioamnionitis and spontaneous preterm birth is mounting. Successful treatment of BV could reduce the rate of late miscarriage and preterm birth. Mucinase and sialidase activity have been implicated in the pathogenesis of BV. This study extends the work of previous studies to investigate sialidase, other known mucin degrading enzymes and overall mucin degrading activity in samples of vaginal fluid from women with and without BV. Samples from 31 women were diagnosed for BV, and tested for enzyme activity using established assays. Activity was recorded in all samples. Significant increases in activity were detected in BV samples for sialidase using a mucin (BSM P<0.005) and serum type glycoprotein (AGP P<0.005) substrates, beta-galactosidase (P<0.001), and beta-N-acetylhexosaminidase (P<0.01). No significant increases in BV patients were detected in O-glycanase, proteinase, arylesterase, sulphatase or whole mucinase activities. These results support the hypothesis that certain BV-associated enzymes may detrimentally affect the mucosal barrier, permitting bacteria access to the uterus.

Enzymes produced in bacterial vaginosis (BV) have been proposed as possible mediators of pre-term birth. Most studies have concentrated on mid-trimester measurements of enzyme activity, and utilize synthetic substrates to measure enzyme activity, which may not accurately represent mucinase activity in vivo. We have developed a novel ELISA mucinase assay using biotinylated human cervical mucin as a substrate. The assay is rapid, sensitive and can be used to screen large numbers of samples. The new assay has been used to assess vaginal mucinase activities in 92 women <14 weeks gestational age with and without BV. No differences in mucinase activity were detected between normal and BV groups while significant elevation of sialidase and other glycosidases was confirmed as reported before. This study shows that significant mucinase activity is a normal event in the mucus barrier, but does not reflect changes identified for individual enzyme activities associated with BV.
