Vaginal probiotics on the outcomes of premature rupture of membranes: a pilot randomised clinical trial

Abstract

The published literature shows that a balanced vaginal microbiota can have a favourable impact on decreasing the prevalence of premature rupture of membranes (PROM). We studied the effects of vaginal probiotics (Lactobacillus rhamnosus and L. gasseri) on the outcomes of PROM in pregnant women between 24 and 36 weeks of gestation. We performed a randomised, triple-blind, placebo-controlled study. A total of 27 participants were divided into two groups—group 1 (probiotics; n = 16) and group 2 (placebo; n = 11). Although most outcomes did not show much variation, the latency period and gestational age at delivery were higher in group 1 than in group 2. Thus, vaginal use of L. rhamnosus and L. gasseri along with standard treatment appears to increase the latency period and gestational age at delivery in women with PROM.

IMPACT STATEMENT

• What is already known on this subject? Delaying delivery increases the risk of infections, but the prolongation of pregnancy allows further foetal maturation, thus reducing the risk of complications associated with premature birth. Moreover, a more extended latency period in pregnancies of <37 weeks of gestation is associated with a better neonatal prognosis.

• What do the results of this study add? The use of probiotics (L. rhamnosus and L. gasseri) prolongs the latency period in pregnant women with premature rupture of membranes.

• What are the implications of these findings for clinical practice and/or further research? Probiotics are an exciting option for extending the time to delivery in cases of premature rupture of the membrane, allowing the maturation of the foetal lung.
