Palmitoylethanolamide and Polydatin in Pediatric Irritable Bowel Syndrome

Overview

This will be a randomised, double-blind, placebo-controlled, parallel-arm trial, designed to study the efficacy and safety of co-micronised palmithoylethanolamide/polydatin in pediatric patients (\> 10 years) with Irritable bowel syndrome (IBS)

The study will include a 2-week screening period, and a 12-week placebo-controlled treatment period . After the screening phase, eligible patients will be randomly assigned to either co-micronised form palmithoylethanolamide/polydatin 200 mg/20 mg, or the equivalent placebo (without the active treatment, replaced by equal amount of microcrystalline cellulose), three times a day, in a 1:1 ratio, for 12 weeks. Study visits were conducted every 4 weeks during the treatment period. All the subjects will be blindly allocated by means of scratch cards to one of the two treatment groups according to a computer-generated randomisation list provided by our statistician. A validated program will be used by an independent statistician to generate a randomisation list with blocks, block size = 4, pre-allocated to centres. Patients and study investigators will be blinded to the randomisation codes. The codes will be kept confidential until the end of the study when the randomisation code will be broken after the database lock. After the screening visit and at the end of treatment all subjects will undergo intestinal permeability test and fecal calprotectin assay. Calprotectin assay will be performed using a commercially available enzyme-linked immunosorbent assay test (Calprest Eurospital, Trieste, Italy). According to the manufacturer, calprotectin levels exceeding 100 mg/kg were considered positive. Intestinal permeability will be evaluated using a liquid chromatography/mass spectrometry method previously published . All subjects will undergo a formal clinical assessment and will be further phenotyped using validated questionnaires. Number of bowel movements per day and/or week and bowel habit characteristics, will be assessed by the Bristol stool scale. The protocol will be approved by an independent ethics committee and conducted according to the Declaration of Helsinki and the principles of good clinical practice. The trial will be registered in a public registry. The primary outcome will be the change in the abdominal pain symptoms (frequency and severity) according to validated score from baseline to the end of the treatment period. Secondary outcome will be modifications of intestinal permeability and fecal caprotectine.
