Polyethylene Glycol Maintenance Treatment for Childhood Functional Constipation: A Randomized, Placebo-controlled...

Area of Science:

• Pediatric Gastroenterology
• Clinical Pharmacology
• Gastrointestinal Motility Disorders

Background:

• Childhood functional constipation (FC) is a common gastrointestinal disorder requiring effective long-term management strategies.
• Maintenance therapy is crucial for preventing symptom relapse after initial disimpaction in pediatric FC.
• The efficacy of polyethylene glycol (PEG) as a long-term maintenance treatment for FC has not been extensively studied in rigorous trials.

Purpose of the Study:

• To evaluate the long-term efficacy of polyethylene glycol (PEG) in the maintenance treatment of childhood functional constipation (FC).
• To compare PEG maintenance therapy against a placebo in a randomized, double-blinded, controlled trial setting.
• To assess the rate of successful treatment and the need for rescue medication over a 24-week period.

Main Methods:

• A randomized, double-blinded, placebo-controlled trial involving children aged 2-16 years diagnosed with FC according to Rome III criteria.
• Participants were assigned to receive either PEG or placebo for 24 weeks of maintenance treatment.
• The primary outcome was successful treatment, defined by the absence of FC symptoms at 24 weeks, with or without medication.

Main Results:

• Significantly more children in the PEG group achieved successful treatment at 24 weeks (67%) compared to the placebo group (36%).
• The PEG group experienced a significantly lower rate of switching to rescue medication (4% vs. 57% in the placebo group).
• No serious adverse events related to PEG use were reported during the study.

Conclusions:

• Long-term maintenance treatment with polyethylene glycol (PEG) is significantly more effective than placebo in preventing relapse of functional constipation symptoms in children.
• The study recommends initiating PEG maintenance therapy after successful disimpaction to ensure sustained symptom control.
• PEG demonstrates a favorable safety profile for long-term use in pediatric functional constipation management.
