Acute diarrhea caused by infections is a common health issue in children, sometimes leading to severe dehydration, hospitalization, or even death. While it typically resolves on its own, researchers are exploring ways to improve recovery, including the use of probiotics. A previous study in Türkiye, known as the PROBAGE study, showed promising results for probiotics in treating acute diarrhea. However, changes in disease patterns, especially post-pandemic, necessitate a fresh look at the effectiveness of probiotics. The PROBAGE 2.0.1 study aims to evaluate the benefits of Lactobacillus rhamnosus GG, a type of probiotic, in treating acute infectious diarrhea in children across Türkiye. This nationwide study involves 480 children with acute infectious diarrhea, who will be divided into two groups. One group will receive the standard care plus Lactobacillus rhamnosus GG (given in a sachet, twice daily for 5 or 10 days), while the other group will receive only the standard care. Stool samples will be collected at the start to identify the causative viruses. The frequency and consistency of stool will be monitored daily for 10 days, either by families for outpatients or by medical professionals for hospitalized children. The study hopes to gather enough data for analysis and publication, contributing to a better understanding of how probiotics can aid in the treatment of acute diarrhea in children.
