PHGG-LGG Synbiotic in Pediatric Functional Constipation (PHGG-LGG-FC)
Effects of a Partially Hydrolyzed Guar Gum and Lacticaseibacillus Rhamnosus GG Combination on Clinical Outcomes and Microbiota in Children With Functional Constipation
調査の概要

条件
詳細な説明
Functional constipation is common in children and has been associated with gut microbiota dysbiosis and impaired short-chain fatty acid production. Synbiotics combining prebiotics and probiotics may improve stool characteristics and intestinal fermentation.
This study investigated whether daily supplementation with PHGG (4.3 g) plus LGG (1×10⁹ CFU) for 12 weeks improves stool frequency, consistency, gastrointestinal symptoms, and microbiota composition compared with standard dietary advice alone. Whole-genome shotgun metagenomics was performed in a subset of participants to characterize microbial and functional changes.
This study was registered retrospectively on ClinicalTrials.gov because it was initiated as an investigator-initiated academic study without initial intent for regulatory submission. Registration was completed after study completion to ensure transparency and compliance with journal and international reporting standards.
