BackgroundChronic constipation is common in children and often requires prolonged laxative treatment. Preliminary studies suggest that the probiotic Limosilactobacillus reuteri (L. reuteri) may be useful in treating constipation in children, but these preliminary results need to be replicated. The objective of this study was to assess the efficacy of L. reuteri in infants and young children with chronic functional constipation.MethodsA prospective double-blind randomized placebo-controlled trial was conducted in 5 pediatric departments in France between June 2017 and June 2021. In all, 49 patients—ages 6 months to 4 years, and suffering from chronic constipation per Rome IV criteria—were randomly allocated to the test and control groups. For 4 weeks, all were orally administered 5 daily drops of the test (L. reuteri DSM 17938 at 108 colony-forming units per day) or control (placebo) treatment, respectively. Participants were clinically assessed at 4 and 8 weeks. Parents were asked to daily record the number of spontaneous bowel movements (SBMs), stool consistency, and the use of any additional laxatives. Informed consent was obtained from parents of all recruited patients, and the study was approved by both an ethics committee and the French National Agency for Medicines and Health Products Safety (ANSM). The study is registered on ClinicalTrials.gov (NCT03030664).ResultsThe change in SBMs relative to baseline was greater in the control group at week 4 (control: 0.27 ± 0.5; test: 0.23 ± 0.5; P = 0.01) and in the test group at week 8 (control: 0.26 ± 0.4; test: 0.22 ± 0.5; P = 0.03). At week 4, the groups did not differ in number of responders (≥3 stools per week, with no non-retentive fecal incontinence), use of rescue medication, scoring of pain during defecation (Faces Pain Scale–Revised), or stool consistency (Bristol Stool Form Scale).ConclusionThis double-blind randomized controlled trial did not confirm the efficacy of L. reuteri for treatment of chronic functional constipation in young children.

Background: Chronic abdominal pain occurs frequently in pediatric patients with inflammatory bowel disease (IBD) in remission. Aims: To assess the prevalence and factors associated with Functional Abdominal Pain Disorders among IBD children in remission (IBD-FAPD). Methods: Patients with IBD for symbolscript 1 year, in clinical remission for symbolscript 3 months were recruited from a National IBD network. IBD-FAPDs were assessed using the Rome III questionnaire criteria. Patient-or parent-reported outcomes were assessed. Results: Among 102 included patients, 57 (56%) were boys, mean age (DS) was 15.0 symbolscript 2.0) years and 75 (74%) had Crohn's disease. Twenty-two patients (22%) had at least one Functional Gastrointestinal Disorder among which 17 had at least one IBD-FAPD. Past severity of disease or treatments received and level of remission were not significantly associated with IBD-FAPD. Patients with IBD-FAPD reported more fatigue (peds-FACIT-F: 35.9 symbolscript 9.8 vs. 43.0 symbolscript 6.9, p symbolscript 0.01) and a lower HR-QoL (IMPACT III: 76.5 symbolscript 9.6 vs. 81.6 symbolscript 9.2, p symbolscript 0.04) than patients without FAPD, and their parents had higher levels of State and Trait anxiety than the other parents. Conclusions: Prevalence of IBD-FAPD was 17%. IBD-FAPD was not associated with past severity of disease, but with fatigue and lower HR-QoL. (C) 2021 The Authors.

ABSTRACTObjectives:Crohn disease (CD) can affect patient's quality of life (QOL) with physical, social, and psychological impacts. This study aimed to investigate the QOL of children with CD and its relationship with patient and disease characteristics.Methods:Children ages from 10 to 17 years with diagnosed CD for more than 6 months were eligible to this cross‐sectional study conducted in 35 French pediatric centers. QOL was assessed by the IMPACT‐III questionnaire. Patient and disease characteristics were collected.Results:A total of 218 children (42% of girls) were included at a median age of 14 years (interquartile range [IQR]: 13‐‐16). Median duration of CD was 3.2 years (IQR: 1.7–5.1) and 63% of children were in clinical remission assessed by wPCDAI. Total IMPACT‐III score was 62.8 (±11.0). The lowest score was in “emotional functioning” subdomain (mean: 42.8 ± 11.2). Clinical remission was the main independent factor associated with QOL of children with CD (5.74 points higher compared with those “with active disease”, 95% confidence interval [CI] 2.77‐‐8.70, P < 0.001). Age of patient at the evaluation was found negatively correlated with QOL (−0.76 per year, 95% CI: −1.47 to −0.06, P = 0.009). Presence of psychological disorders was associated with a lower QOL (−9.6 points lower to those without, 95% CI: −13.34 to −5.86, P < 0.0001). Total IMPACT‐III and its subdomains scores were not related to sex, disease duration, or treatments.Conclusions:These results not only confirm that clinical remission is a major issue for the QOL of patients, but also highlights the importance of psychological care.

Purpose: Mowat-Wilgon syndrome (MWS) is a developmental disorder presenting with mental retardation, delayed motor development, and a wide spectrum of clinical features. Hirschsprung's disease (HD) is associated in almost 50% of cases. This report aims to analyze the course of HD and to evaluate the clinical outcomes of these patients.Patients and methods: Between 1997 and 2007, 110 patients presenting with HD were diagnosed and managed in our institution. Five of them presented the association of HD and MWS. Their records were reviewed retrospectively.Results: All of the 5 patients have a genetic disorder specific of MWS (nonsense mutation or deletion on SIPI gene, locus 2q22). Two patients underwent transanal endorectal pull-through procedure for classic rectosigmoid HID. Three patients were operated on for total colonic aganglionosis using Duhamel procedure. The median follow-up was 4 (range, 0.3-7) years. Only one patient is doing well (rectosigmoid HID). Two patients have a stoma diversion for severe motility disorders. Of the 3 total colonic aganglionosis, one still has repeated episodes of obstruction requiring total parenteral nutrition (TPN). The 2 others still have repeated episodes of enterocolitis. All patients required a prolonged TPN (32.5 months in average).Conclusion: Hirschsprung's disease associated with MWS is a severe condition. Even in case of short segment HD, patients can present motility disorder requiring a prolonged TPN. Physician and surgeon should be aware about the evolution of this rare condition.
