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

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: BACILLUS CLAUSII

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.
Dietary supplement: Bacillus clausii

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.
Active Comparator: SACCHROMYCES BOULARDII

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.
Dietary supplement: Saccharomyces boulardii

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.

What is the study measuring?

Primary Outcome Measures
