Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Pregnant women at high risk for preterm labor from at least 13 weeks of gestation will be tested to detect abnormal vaginal flora (AVF) or its severe form - bacterial vaginosis (BV) by taking vaginal smear. Treatment will be given according to the results.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Pregnant women at high risk for preterm labor from at least 13 weeks of gestation will be tested to detect AVF/BV by taking vaginal smear. Diagnosis will be according to the Nugent score criteria. Treatment will be given according to the results:

Patient with a positive smear for AVF- patients tested positive will be treated with either clindamycin or metronidazole. Following treatment another smear will be taken according to which the patients will be divided into 2 research groups: (1) Assessing the effectiveness of probiotic formula to prevent AVF re-infection (secondary infection) - this group includes patients with normal vaginal flora following antibiotic administration. (2) Assessing the effectiveness of probiotic formula to eradicate AVF - this group includes patients with persistent AVF following antibiotic administration (first and second line). In each group the patients will be divided into a research group which will receive the probiotic formula UREX PLUS (containing L. rhamnosus GR-1and L. reuteri RC-14) and a control group which will receive a placebo twice a day until 36.6 weeks of gestation.

Patient with a negative smear for AVF - in those patients the effectiveness of probiotic formula will be tested for primary prevention. These patients will be divided into a research group which will receive the probiotic formula UREX PLUS and a control group which will receive a placebo twice a day until 36.6 weeks of gestation.

Finally, the colonization of lactobacilli in the vaginal flora will be examined by dividing patients with normal vaginal flora into one group receiving a probiotic capsule containing L. rhamnosus GR-1 and L. reuteri RC-14 twice a day for 2 months and a second group without intervention. After two months the group receiving probiotic capsule will receive no treatment and the second group will receive probiotic capsule containing L. rhamnosus GR-1and L. reuteri RC-14 twice a day for 2 months.

Lactobacilli transfer - probiotic capsule

Patients with Normal vaginal flora will be treated with a probotic capsule containing L. rhamnosus GR-1and L. reuteri RC-14 for two months afterwhich they will receive no treatment for additional two months. Lactobacili colonization in the vaginal flora will be tested

Group Type OTHER

Intervention Type DIETARY_SUPPLEMENT

Lactobacilli transfer - probiotic capsule after 2 months

Patients with Normal vaginal flora will be followed for two months without intervention afterwhich they will receive a probotic capsule containing L. rhamnosus GR-1and L. reuteri RC-14 for two months. Lactobacili colonization in the vaginal flora will be tested.
