About this study
Official title: Comparison of the Clinical Efficacy of Bacteria-Based Probiotics to Fungi-Based Probiotics in Acute Watery Diarrhea in Pediatric Outpatient Department
THIS STUDY WILL BE CONDUCTED ON OPD PATIENTS IN CENTRAL PARK TEACHING HOSPITAL LAHORE TO SEE THE EFFECT OF PROBIOTICS ON DIARRHEA ALL PATIENTS INCLUDED WILL HAVE ACUTE WATERY DIARRHEA AND THE OUTCOME WILL BE CHECKED ON THE THIRD DAY OF ADMISSION
Read the detailed description
This study is planning to compare the clinical efficacy of bacterial ( Bacillus clausii) versus fungal (Sacchromyces boulardii) probiotic in acute watery diarrhea. A clear consensus has not been reached regarding the use of appropriate probiotic. Some pediatricians are of the opinion that bacterial probiotic are suprerior to fungal probiotics along with rehydration for improvement of diarrhea. However, others experience is that fungal probiotics are better along with rehydration for the improvement of diarrhea. A high-quality evidence basis must be established that guides the pediatrician regarding the choice of probiotic.The results of this study will help guide pediatricians to the better probiotic for the clinical improvement of acute diarrhea in our setup.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Bacillus clausiiDietary supplement
Bacillus clausii, a bacterial-based probiotic, will be administered orally at a dose of 2 billion spores twice daily for 3 days, in addition to standard diarrheal treatment. Clinical efficacy will be assessed on the 3rd day based on stool frequency and consistency.
Saccharomyces boulardiiDietary supplement
Saccharomyces boulardii, a fungal-based probiotic, will be administered orally at a dose of 250 mg twice daily for 3 days, in addition to standard diarrheal treatment. Clinical efficacy will be assessed on the 3rd day based on stool frequency and consistency.
| Study group | Role | What they receive |
|---|---|---|
| BACILLUS CLAUSII | Active comparator | Participants will receive bacterial-based probiotic Bacillus clausii (2 billion spores), administered orally twice daily, in addition to standard diarrheal treatment. Participants will be followed for 3 days to assess clinical efficacy based on stool frequency and consistency. Receives: Dietary Supplement: Bacillus clausii |
| SACCHROMYCES BOULARDII | Active comparator | Participants will receive fungal-based probiotic Saccharomyces boulardii 250 mg, administered orally twice daily, in addition to standard diarrheal treatment. Participants will be followed for 3 days to assess clinical efficacy based on stool frequency and consistency. Receives: Dietary Supplement: Saccharomyces boulardii |
What is being measured
The primary outcome is the main question the study is designed to answer.
Clinical efficacy of probiotic treatment
Clinical efficacy will be assessed on the 3rd day. A positive outcome will be defined as ≤3 episodes of stool with Bristol stool grade 5 or less. The clinical efficacy of Bacillus clausii will be compared with Saccharomyces boulardii in children with acute watery diarrhea.
Measured: 3 days

A study testing Bacillus clausii and Saccharomyces boulardii in people with Acute Watery Diarrhea, run by Syeda Sabeen Fatima Naqvi at 1 site in Pakistan.
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 3 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: under way, not looking for participants, as of the sponsor's last update on 2 Oct 2026. 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 Pakistan. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
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?
Clinical efficacy of probiotic treatment (time frame: 3 days). 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 NCT07853846, which also lists 6 linked publications.
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 2 Oct 2026.
