Oral Probiotics for the Treatment and Prevention of Vulvovaginal Infections in Pregnancy - Double-blind, Randomized, Placebo-controlled Study

Not Applicable
Completed
Conditions
Bacterial Vaginosis and Vaginal Candidiasis At Pregnancy
Interventions
Dietary Supplement: Probiotic Capsule containing L. acidophilus, L. Paracasei, L. Rhamnosus, streptococcus thermophilus and Bifidobacterium bifidum
Other: Placebo
Registration Number
NCT02795845
Lead Sponsor
HaEmek Medical Center, Israel
Brief Summary

During pregnancy, bacterial vaginosis (BV), abnormal vaginal flora (AVF) and vulvovaginal candidiasis (VVC) are associated with serious complications and discomfort. Yet, treatment options are limited. Lactobacilli administration was suggested to treat and prevent vaginal infections. However, this has not been examined in pregnant women, the information regarding oral treatment is scarce, and the mechanisms in which oral ingestion of probiotics induce vaginal lactobacilli proliferation are not well established. In the present study we will examine if oral probiotics are effective in prevention of vaginal infections by migration of lactobacilli from the digestive system to the vagina in pregnant women.

Detailed Description

During pregnancy, bacterial vaginosis (BV), abnormal vaginal flora (AVF) and vulvovaginal candidiasis (VVC) are associated with serious complications and discomfort. Yet, treatment options are limited. Lactobacilli administration was suggested to treat and prevent vaginal infections. However, this has not been examined in pregnant women, the information regarding oral treatment is scarce, and the mechanisms in which oral ingestion of probiotics induce vaginal lactobacilli proliferation are not well established.

Working hypothesis: Oral probiotics will be effective in prevention of vaginal infections by migration of lactobacilli from the digestive system to the vagina in pregnant women.

Type of research and methods of data collection: randomized placebo-controlled trial.

Pregnant patients with symptoms consisted with vaginal infection will be examined and vaginal smear will be obtained, according to which the patients will be allocated to the following groups:

Primary prevention - women with normal vaginal flora Secondary prevention - women positive for AVF/BV and/or VVC- those women will be treated with antibiotic and/or antimycotic treatment. Following treatment, another smear will be taken to confirm infection eradication. If infection is still present, additional antibiotic and/or antimycotic treatment will be administered after which additional smear will be taken. Women with normal vaginal flora (after one of two treatments) will be recruited for the secondary prevention group.

In each group the patients will be divided into two subgroups, which will receive one capsule twice a day of either the Probiotic Femina ׀׀ capsules or placebo.

At the initial examination and once a month all the study groups will be tested for the presence of AVF/BV and candida. Additional vaginal samples will be taken to evaluate the presence of lactobacilli from the capsule and semi-quantitative assessment of vaginal lactobacilli.

Primary prevention- probiotic capsulesProbiotic Capsule containing L. acidophilus, L. Paracasei, L. Rhamnosus, streptococcus thermophilus and Bifidobacterium bifidumpatients with normal vaginal flora in the experimental arm will be treated with Probiotic capsules (containing L. acidophilus, L. Paracasei, L. Rhamnosus, streptococcus thermophilus, Bifidobacterium bifidum and B. Lactis). one capsule twice a day until delivery.
Primary prevention - PlaceboPlacebopatients with normal vaginal flora in the placebo arm will be treated with a capsule without active ingredient, one capsule twice a day until delivery.
Secondary prevention - probiotic capsulesProbiotic Capsule containing L. acidophilus, L. Paracasei, L. Rhamnosus, streptococcus thermophilus and Bifidobacterium bifidumPatients with abnormal vaginal flora/bacterial vaginosis or vaginal candidiasis in the experimental arm will be treated with antibiotic (either clindamycin, metronidazole or both if necessary) or antimycotic treatment. Once the infection was eradicated, the patient will be given probiotic capsules.
Secondary prevention - PlaceboPlaceboPatients with abnormal vaginal flora/bacterial vaginosis or vaginal candidiasis in the experimental arm will be treated with antibiotic (either clindamycin, metronidazole or both if necessary) or antimycotic treatment. Once the infection was eradicated, the patient will be given placebo without active ingredient.
Primary Outcome Measures
NameTimeMethod
The rate of women in the second prevention group who developed any vaginal infection (BV/AVF/VVC) during the study period until delivery in the probiotic formula group versus placebo.Until delivery (around 4 months)
The degree of vaginal lactobacilli colonization in the probiotic formula group versus placeboAround 4 months

Lactobacilli culture will be made from a vaginal specimen. The pattern of bacterial growth will be used for a semi-quantitative interpretation in a scale of 0-no vaginal colonization to 4-substantial colonization.

The rate of women in the primary prevention group, who developed any vaginal infection (BV/AVF/VVC) during the study period until delivery in the probiotic formula group versus placebo.From date of randomization until the date of first documented episode or until delivery (around 4 months)
Secondary Outcome Measures
NameTimeMethod
The rate of women, who suffer from obstetrical complicationsFrom randomization until delivery (around 4 months)

preterm labor, intrauterine growth restriction (IUGR), PPROM, chorioamnionitis, post-partum fever, post-partum endometritis

The rate and type of adverse effects in the probiotic versus placebo groups (e.g gastrointestinal symptoms).From randomization until two weeks after delivery (around 4 months)
Number of urinary tract infections during the study periodFrom randomization until delivery (around 4 months)
The number of episodes of vaginal infections during pregnancy (either AVF/BV or VVC).From randomization until delivery (around 4 months)
The rate of women in the primary prevention group who developed VVC during the study period until delivery in the probiotic formula group versus placebo.From randomization until delivery (around 4 months)
The rate of women in the second prevention group who developed AVF/BV during the study period until delivery in the probiotic formula group versus placebo.From randomization until delivery (around 4 months)
The rate of women in the primary prevention group who developed AVF/BV during the study period until delivery in the probiotic formula group versus placebo.From randomization until delivery (around 4 months)
The rate of neonatal complications30 days after delivery

Neonatal acute respiratory distress syndrome, intraventricular hemorrhage, neonatal sepsis, admission to the neonatal intensive care unit

Duration of time from the beginning of the study until an episode of vaginal infection (either AVF/BV or VVC).From randomization until delivery (around 4 months)
The rate of women in the second prevention group who developed VVC during the study period until delivery in the probiotic formula group versus placebo.From randomization until delivery (around 4 months)
