Overview

This study aims to evaluate the efficacy and palatability of a developed polyethylene glycol-based formula compared with the standard polyethylene glycol (PEG) in the treatment of children with functional constipation for 8 weeks. Besides, we also aim to assess the side effects of a developed PEG-based formula as well as evaluate the change of rectal diameter from baseline at each visit between 2 groups.

Detailed description

Total 52 children age 6 months to 18 years old diagnosed with functional constipation will be enrolled in this study. They will be randomised in Group A or Group B.

Children in group A will receive PEG-Chula at a dose of 0.5 - 1 g/kg/day for a duration of 56 days.

Children in group B will receive the standard PEG formula (Forlax) at a dose of 0.5 - 1 g/kg/day for a duration of 56 days.

PEG-Chula and standard PEG will be prepared in sachets with similar packaging and appearance labelled A, B, C, D.

Children in both groups will also receive counseling on toilet training, water intake, and fiber intake in the same manner.

Parents will be advised to record symptoms, dietary intake, and dose of medication in a logbook.

Children will visit the researchers on days 7, 14, 28, and 56 to collect data on symptoms, stool diameter, bowel size measured by ultrasound, side effects, and medication compliance. Children with poor compliance will be excluded from the study.

Interventions

  • Drug Local PEG4000
    PEG-Chula is developed from PEG 4000 used at King Chulalongkorn Memorial Hospital with added sweetener and flavours. Children will be given PEG-Chula at a dose of 0.5 - 1 g/kg/day.
  • Drug Commercial PEG4000
    For commercial PEG, We use Forlax as the control group. Children will be given Forlax at a dose of 0.5 - 1 g/kg/day.

Primary outcome measures

  • The frequency of stool [Time frame: At 7 days, 14 days, 28 days and 56 days]
  • Stool consistency assessed by Bristol stool chart [Time frame: At 7 days, 14 days, 28 days and 56 days]
Secondary outcome measures (6)
  • Fecal incontinence [Time frame: At 7 days, 14 days, 28 days and 56 days]
  • Rectal diameter measured by transabdominal ultrasonography [Time frame: At 7 days, 14 days, 28 days, 56 days and 2 years]
  • Anterior wall thickness measured by transabdominal ultrasonography [Time frame: At 7 days, 14 days, 28 days, 56 days and 2 years]
  • Adverse events [Time frame: At 7 days, 14 days, 28 days and 56 days]
  • Palatability of medication assessed by facial Hedonic scale [Time frame: At 7 days, 14 days, 28 days and 56 days]
  • Change of gut microbiota before and after treatment [Time frame: At baseline and 56 days]
