Effect of Probiotics on Constipation and Weight in CP

ClinicalTrials.gov Study Record Example Title The Effect of Using Lactobacillus reuteri and Prebiotic-Containing Lactobacillus rhamnosus Strains on Constipation and Weight Gain in Children with Cerebral Palsy: A Prospective Randomized Controlled Study ________________________________________ Brief Summary This clinical trial aims to determine whether daily supplementation with Lactobacillus reuteri or a prebiotic-enriched Lactobacillus rhamnosus formula can improve constipation and weight gain in children with cerebral palsy (CP). Constipation is a common problem in children with CP due to impaired intestinal motility and disruption of the gut microbiota. The study will compare the effects and safety of two probiotic products over a 28-day period.

________________________________________ Detailed Description Cerebral palsy (CP) is a non-progressive neurodevelopmental disorder characterized by impairments in movement and posture. Gastrointestinal complications, particularly chronic constipation and inadequate weight gain, are frequently observed in this population and may significantly affect quality of life. Altered intestinal motility, limited physical activity, and gut microbiota dysbiosis are considered key contributors to bowel dysfunction in children with CP.

Probiotics have been proposed as a supportive therapeutic approach for gastrointestinal symptoms through modulation of intestinal microbiota, enhancement of barrier function, and regulation of bowel motility. Lactobacillus reuteri and Lactobacillus rhamnosus are among the most commonly studied probiotic strains with documented benefits in pediatric gastrointestinal disorders. The addition of prebiotics such as inulin may further enhance probiotic efficacy by promoting the growth of beneficial bacteria.

This prospective, randomized, double-blind, controlled study is designed to evaluate the effects of daily probiotic supplementation on bowel habits and growth parameters in children with cerebral palsy. Eligible participants are allocated to one of three parallel intervention arms and followed for a 28-day treatment period.

Clinical assessments are conducted at baseline and at the end of the intervention period. Anthropometric measurements are obtained using standardized techniques. Stool samples are collected for laboratory analysis, and stool consistency is evaluated using a validated scoring system. Caregivers maintain a daily stool diary to document bowel movement frequency and gastrointestinal symptoms throughout the study period.

The study evaluates changes in bowel function and growth-related parameters over time, as well as the safety and tolerability of the probiotic formulations. Adverse events and treatment adherence are monitored throughout follow-up. This study aims to provide evidence on whether probiotic supplementation represents a safe and effective supportive strategy for managing constipation and improving nutritional outcomes in children with cerebral palsy.
