About

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.

Full 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.

157 participants in 4 patient groups, including a placebo group

Primary prevention- probiotic capsules

Experimental group

Description:

patients 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.

Treatment:

Dietary Supplement: Probiotic Capsule containing L. acidophilus, L. Paracasei, L. Rhamnosus, streptococcus thermophilus and Bifidobacterium bifidum

Primary prevention - Placebo

Placebo Comparator group

Description:

patients with normal vaginal flora in the placebo arm will be treated with a capsule without active ingredient, one capsule twice a day until delivery.

Treatment:

Other: Placebo

Secondary prevention - probiotic capsules

Experimental group

Description:

Patients 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.

Treatment:

Dietary Supplement: Probiotic Capsule containing L. acidophilus, L. Paracasei, L. Rhamnosus, streptococcus thermophilus and Bifidobacterium bifidum

Secondary prevention - Placebo

Placebo Comparator group

Description:

Patients 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.
