Group B Streptococcus Response After Probiotic Exposure
United States68 participantsStarted 2020-12-24
Plain-language summary
This is an open-label randomized control trial and feasibility study designed to determine the feasibility of a larger RCT in our setting that would examine prenatal probiotic use in Group B Strep (GBS) positive pregnant women at term. Investigators hope to address the question of whether prenatal oral probiotic use, taken by healthy low risk GBS positive women from approximately 37 weeks gestation until the time of birth, will reduce the number of women who test positive for GBS at the time of admission to Labor and Delivery (L\&D).

* No obstetric complication requiring delivery prior to 39 weeks (hypertensive disorder diagnosed prior to enrollment, gestational diabetes, multiple gestation)
* No fetal complication (e.g., birth defect, intrauterine growth restriction)
* No medical complication (e.g., chronic hypertension, preexisting diabetes mellitus)
* Who do not currently ingest an over the counter probiotic supplement (not including yogurt)
* Who can both speak and read English or Spanish
* Pregnant women who regularly attend UNM prenatal clinics for their prenatal care ("regularly attend" will be defined as starting prenatal care prior to 20 weeks gestation and missing no more than one prenatal appointment during this pregnancy)
* No hypersensitivity reaction to β-lactam antibiotics
Exclusion Criteria:
* Those less than 18 years of age
* Non-pregnant women
* Later in pregnancy than 38 weeks gestation at enrollment \[per LNMP and/or US\]
* Those with an obstetric, fetal or medical complication of pregnancy
* Group B Streptococcus negative at 36 weeks gestation. Those ineligible for testing at 36 weeks gestation (history of GBS bacteriuria during the current pregnancy or have previously given birth to a GBS affected child.) We…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
