Brief Summary:
An interventional, randomized, multicenter, double-blind, placebo-controlled, parallel-group study will be conducted to evaluate the effectiveness of the strain Lactobacillus salivarius V4II-90 in the reduction of Group B Streptococcus (GBS) colonization in pregnant women who are GBS carriers. Forty GBS-positive participants in their first trimester of pregnancy will be randomly assigned to one of the two study groups: The experimental group with 3 months probiotic consumption; and the control group with 3 months placebo consumption. The efficacy of the probiotic strain to reduce the incidence of Group B Streptococcus will be assessed by the percentage of participants with a vaginal and/or rectal detection of Group B Streptococcus at the end of the study, by bilateral comparison of the treatment group with the control group at the same time period. The estimated duration of the study will be 30 weeks, which includes a 3-month product administration. The intervention will start at week 23 ± 4 days of pregnancy and end at week 35 ± 4 days. Then, a visit will be completed one month after delivery.
Detailed Description:
All pregnant women reporting to the clinic in their first trimester of pregnancy (week 11 ± 2 weeks of pregnancy) will be asked to participate in this study. Participation will be voluntary and written informed consent will be obtained from each participant. The study visits will take place in the hospital.
At Visit 1, the inclusion and exclusion criteria will be verified. After signing the informed consent, a physical examination will be performed in addition to a vaginal-rectal smear to detect if they are GBS-positive. Information on the demographic profile and medical history will be collected. The investigator will explain to the participant that she cannot use any probiotic during the course of the study.
At Visit 2, within 21-23 weeks ± 4 days of gestation, the inclusion and exclusion criteria will be reviewed. When a positive result of the microbiological analysis of the vaginal-rectal exudate are obtained, the pregnant GBS+ women will be invited to continue in the study. The randomized participant will intake one capsule of probiotic or placebo every day for the next 12 weeks. The participant will be given a diary and instructions to record the product intake. Adverse events occurring from the time of study inclusion will be recorded. Adverse Events occurring from the time of study inclusion will be recorded.
At the third visit (Visit 3, 35 weeks ± 4 days of gestation), all participants continuing in the study will undergo a general physical examination. A sample of vaginal and rectal exudate will be collected from the participants who end the treatment period. Adverse Events occurring during the period between Visit 2 and Visit 3 will be recorded. The participants must deliver the remaining product and the completed diary.
During Visit 4 (1 month after delivery), all participants will have a general physical examination. Adverse Events occurring since Visit 3 will be recorded. Data will be collected on the delivery and occurrence of early- or late-onset GBS sepsis in the newborn during the first month of life.
