About this study
The aim of this study is to assess the effect of Lactobacillus reuteri DSM 17938 administration for the prevention of diarrhea and AAD in children.
Read the detailed description
Introduction:
Addition of some probiotics appears to reduce the risk of antibiotic-associated diarrhea (AAD). Effects of probiotics are strain specific, thus the efficacy and safety of each probiotic strain should be established separately. We aim to assess the effect of Lactobacillus reuteri DSM 17938 administration for the prevention of diarrhea and AAD in children.
Methods and analysis:
A total of 250 children younger than 18 years treated with antibiotics will be enrolled into a double-blind, randomized placebo-controlled trial in which they will additionally receive L reuteri DSM 17938 at a dose 2 x 10^8 colony-forming units or an identically appearing placebo, orally, twice daily, for the entire duration of antibiotic treatment. The primary outcome measures will be the frequency of diarrhea and AAD. Diarrhea will be defined according to one of 3 definitions: (a) ≥3 loose or watery stools per day for a minimum of 48 hours during antibiotic treatment; (b) ≥3 loose or watery stools per day for a minimum of 24 hours during antibiotic treatment; (c) ≥2 loose or watery stools per day for a minimum of 24 hours during antibiotic treatment. AAD will be diagnosed in cases of diarrhea, defined clinically as above, caused by C. difficile or for otherwise unexplained diarrhea (i.e. negative laboratory stool tests for infectious agents).

What is being measured
The primary outcome is the main question the study is designed to answer.
frequencies of diarrhea and antibiotic associated diarrhea
Three different definitions of diarrhea will be used, as the definitions of diarrhea/AAD in published studies vary. These will include diarrhea defined as: (a) ≥3 loose or watery stools per day for a minimum of 48 hours during antibiotic treatment; (b) ≥3 loose or watery stools per day for a minimum of 24 hours during antibiotic treatment, and (c) ≥2 loose or watery stools per day for a minimum of 24 hours during antibiotic treatment. AAD will be diagnosed in cases of diarrhea, defined clinically as above, caused by C. difficile or for otherwise unexplained diarrhea (i.e., negative laboratory stool tests for infectious agents). In all cases, loose or watery stools will correspond to scores of 5 to 7 on the BSF scale or A-consistency on the AISS.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Lactobacillus reuteri DSM 17938 in people with Diarrhea and Antibiotic Associated Diarrhea, run by Medical University of Warsaw at 1 site in Poland.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 20 Mar 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Poland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
frequencies of diarrhea and antibiotic associated diarrhea (time frame: during antibiotic treatment, an average of 10 days and 7 days of follow up). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02871908, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Mar 2018; AzTrials last refreshed its copy on 8 Nov 2026.
