- Conditions
- Functional Constipation
- Interventions
- Other: placebo - with no active ingredientDietary Supplement: probiotic - Lactobacillus reuteri
- Registration Number
- NCT03333070
- Lead Sponsor
- HaEmek Medical Center, Israel
- Brief Summary
Functional constipation (FC) is a common condition in childhood, with an estimated prevalence of 0.7% to 29%.The diagnosis and treatment of FC can be difficult tasks, and children are often referred to specialist services causing treatment to become expensive and time-consuming.The standard treatment based on osmotic laxatives (mainly PEG). The recovery rate is 50% to 60% after 1 year of treatment, with 50% of the children having relapse within 5 years. Studies in adults have established the effectiveness of some lactic acid bacteria in the treatment of chronic constipation.
- Detailed Description
Functional constipation (FC) is a common condition in childhood, with an estimated prevalence of 0.7% to 29%.The diagnosis and treatment of FC can be difficult tasks, and children are often referred to specialist services causing treatment to become expensive and time-consuming.The standard treatment based on osmotic laxatives (mainly PEG). The recovery rate is 50% to 60% after 1 year of treatment, with 50% of the children having relapse within 5 years. Studies in adults have established the effectiveness of some lactic acid bacteria in the treatment of chronic constipation.However, it is unclear whether similar effects occur in children. Lactobacilli and Bifidobacteria are the most studied species showing a high safety profile. Both are able to promote colonic peristalsis which could be beneficial for the treatment of constipation .Even though traditional treatment is well established and safe, high proportion of children need prolonged treatment for several months or even years. For many parents there is a concern regarding prolonged treatment with PEG .Lactobacilli, bifidobacteria and FOS (fructooligosaccharide) increase stool frequency and decrease consistency in healthy adults and therefore could prevent recurrence of constipation after PEG withdrawal .The principle investigator hypothesize that treatment with probiotics adjunct to PEG and several months thereafter could decrease the proportion of children needed permanent or prolonged treatment (\>12 months) with PEG.
The importance of the study and its practical benefits:
Treatment with PEG for FC is well established and is considered safe. Despite that, a high proportion of children need prolonged treatment for several months or even years. For many parents there is a concern regarding prolonged treatment with PEG. Previous studies did not demonstrate efficacy of treatment with probiotics or prebiotics in FC. Neither of these studies assessed effectiveness probiotics/prebiotic products as adjunct to the traditional treatment (PEG) of FC in shortening its period.
A recently published studies including from Israel, demonstrated efficacy of Lactobacillus reuteri in irritable bowel syndrome, infantile colic and functional abdominal pain .Therefore, demonstration of positive effect of treatment with probiotic product in FC, could imply for potential use of this product in other functional gastrointestinal disorders among children.

Group Intervention Description Placebo Arm placebo - with no active ingredient 25 consecutive children diagnosed with functional constipation will be treated with full dose PEG (Polyethylene glycol 3350) treatment (dose of \~1g/kg/day) for 12 weeks. After 12 weeks of treatment they will be randomized: control arm will receive placebo for 12 weeks while tapering the PEG dose Dose of 5 drops per day for 48 weeks Treatment Arm probiotic - Lactobacillus reuteri 25 consecutive children diagnosed with functional constipation will be treated with full dose PEG (Polyethylene glycol 3350) treatment (dose of \~1g/kg/day) for 12 weeks. After 12 weeks of treatment they will be randomized: treated arm will receive probiotic containing Lactobacillus reuteri for 12 weeks while tapering the PEG dose Dose of 5 drops per day for 48 weeks
