This study found that the presence of lactobacilli in the vaginal flora of pregnant women did not protect against preterm labor. Further research is needed to understand the role of vaginal microbiota in pregnancy outcomes.

Area of Science:

  • Obstetrics and Gynecology
  • Microbiology
  • Perinatal Health

Background:

  • Vaginal flora composition, particularly the presence of Lactobacillus species, is crucial for maintaining a healthy pregnancy.
  • Preterm labor remains a significant concern, necessitating research into its causes and potential preventative measures.

Purpose of the Study:

  • To investigate the prevalence of Lactobacillus species in the vaginal flora of pregnant women.
  • To evaluate the potential protective effect of lactobacilli against preterm labor.

Main Methods:

  • A cross-sectional analysis was conducted on 480 pregnant women aged 13-48 years attending their first antenatal visit.
  • Vaginal flora cultures were analyzed for the presence of Lactobacillus species and other aerobes.
  • Outcomes assessed included preterm labor (before 34 and 37 weeks), premature rupture of membranes, intrauterine growth retardation, and perinatal deaths.

Main Results:

  • Lactobacilli were detected in the vaginal flora of a significant proportion of the pregnant women studied.
  • The incidence of preterm labor (before 37 weeks) was similar in women with and without lactobacilli in their vaginal flora (18% vs. 20%).
  • No significant difference in perinatal outcomes was observed between groups based on the presence or absence of lactobacilli.

Conclusions:

  • The findings suggest that lactobacilli in the vaginal flora do not appear to offer a protective effect against preterm labor in high-risk pregnant populations.
  • Further investigation is warranted to elucidate the complex interplay between vaginal microbiota and adverse pregnancy outcomes.
