Preterm labor - Bacterial vaginosis

Bacterial vaginosis:
Bacterial vaginosis is associated with excess rates of preterm birth.
 Oral metronidazole found to resolve bacterial vaginosis for at least 10 wks in 78% of treated pregnant women.
Metronidazole plus erythromycin or metronidazole plus azithromycin can also be used.
 Studies in which earlier treatment was initiated are more promising.
 Oral clindamycin 300mg twice daily for 5 days associated with fewer pregnancy losses between 13 to 24 weeks and fewer spontaneous preterm births.
If women with bacterial vaginosis underwent in vitro fertilization, rate of conception is similar but an increased risk of first trimester loss compared with that of uninfected women.
Group B streptococcus(GBS) can cause clinical infections in pregnant women, but most women are asymptomatic.
Presence of GBS colonization in pregnancy has not been found to increase rates of preterm delivery.
