Study summary

Prevalence of uro-genital infections during pregnancy move between 7% to 12% in developed countries, meanwhile in developing countries this figure moved between 14% and until 55%, such is the case of Mexico. Meanwhile use of antibiotics for 3 to 7 days had established as a standard of care, the use of non-antibiotic therapy, such as cranberry powder or probiotics for prevention/treatment of this conditions is scarce. Randomized controlled trial aimed to evaluate the safety and efficacy of probiotic vs. antibiotics to treat pregnant women with uncomplicated cystitis or asymptomatic bacteriuria

Read the detailed description

Randomized controlled trial, aimed to evaluate the efficacy of Lactobacillus reuteri DSM 16666/ATCC 55845 \& Lactobacillus reuteri DSM 17938 for the treatment of pregnant women with asymptomatic bacteriuria or uncomplicated acute cystitis. As primary outcome we will evaluate the number of cases with clinical (symptoms severity) or bacteriological cure in pregnant women with uncomplicated cystitis or asymptomatic bacteriuria after 7 days treatment with probiotics vs. placebo. As secondary outcome we will evaluate a) rate of recurrence cases in each group; b) time to relapse; c) frequency of pyelonephritis; d) birth weight and head circumference; d) number of cases of preterm babies (less than 36 weeks of gestation); e) frequency of antibiotic as rescue treatment; f) frequency of adverse related events in each arm and g) frequency of preeclampsia. Women on active group will receive a combination of at least 5*10\^8 CFU of Lactobacillus reuteri DSM 16666/ATCC 55845 \& Lactobacillus reuteri DSM 17938, PAC-A and Zinc. Women in control group will receive o Amoxicillin + clavulanic acid (500 mg twice daily) for seven days in patients with negative nitrites in dipstick or oral nitrofurantoin (200mg twice per day) ror patients with positive dipstick.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Dec 2017 to primary completion in Dec 2018, 12 months.

Of 136 non-industry interventional studies with no phase under Urinary Tract Infections, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 8 and three quarters within 39. This study's 12 months is below that.

Counting every sponsor, half of 153 studies reached it within 22 months; a quarter within 8 and three quarters within 37.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 20, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
