Plain language summary
Inflammatory bowel diseases (IBD), such as Crohn’s Disease and ulcerative colitis, are chronic gastrointestinal disorders with periods of exacerbation and remission. The disease develops as a result of an abnormal immune response in the gastrointestinal mucosa in genetically predisposed individuals exposed to certain environmental conditions. The primary aim of this study was to evaluate the effectiveness of oral sodium butyrate as an add-on to standard therapy in children and adolescents with newly diagnosed IBD. This study is a prospective, randomised, and placebo-controlled trial. Patients (n = 80) were randomised and assigned to one of two groups: group A received butyric acid at a dose of 150 mg, and group B received 150 mg placebo. Results show that supplementation with sodium butyrate to be ineffective in the add-on treatment of newly diagnosed children and adolescents with IBD. Furthermore, during the study, none of the participants reported adverse events. Authors conclude that the results of their study will contribute to further studies that will determine which patients with IBD may benefit from sodium butyrate supplementation. Further clinical trials on large groups of patients are needed to establish if IBD patients may benefit from sodium butyrate.
Abstract
BACKGROUND Butyric acid's effectiveness has not yet been assessed in the pediatric inflammatory bowel disease (IBD) population. This study aimed to evaluate the effectiveness of oral sodium butyrate as an add-on to standard therapy in children and adolescents with newly diagnosed IBD. METHODS This was a prospective, randomized, placebo-controlled multicenter study. Patients aged 6-18 years with colonic Crohn's disease or ulcerative colitis, who received standard therapy depending on the disease's severity, were randomized to receive 150 mg sodium butyrate twice a day (group A) or placebo (group B). The primary outcome was the difference in disease activity and fecal calprotectin concentration between the two study groups measured at 12 weeks of the study. RESULTS In total, 72 patients with initially active disease completed the study, 29 patients in group A and 43 in group B. At week 12 of the study, the majority of patients achieved remission. No difference in remission rate or median disease activity was found between the two groups (p = 0.37 and 0.31, respectively). None of the patients reported adverse events. CONCLUSIONS A 12-week supplementation with sodium butyrate, as adjunctive therapy, did not show efficacy in newly diagnosed children and adolescents with IBD.

Plain language summary
Oats have been allowed in the gluten-free diet of patients with coeliac disease (CD), however concerns have been raised that they may not be safe to eat in a subset of these patients. Short chain fatty acids (SFCAs) have been identified as a marker of inflammation and gut metabolism. Recent studies have found that children with CD often have elevated SCFA levels, indicating a disturbance in the gut microflora. The aim of this study was to identify the effect of consuming oats in children recently diagnosed with CD by examining faecal SCFAs. 116 children were treated with or without oats in their gluten-free diet for one year to see if oats affect the gut microflora. The findings of this study indicate that the children consuming oats had higher faecal SCFA concentration after one year than those not consuming oats. Based on this study, the authors’ conclude that oats do affect the gut microflora metabolism and that some coeliac children consuming oats may develop gut mucosal inflammation, leading to further future complications.
Abstract
BACKGROUND Faecal short chain fatty acids (SCFAs) are produced by the gut microflora. We have previously reported high faecal SCFA levels in children with coeliac disease (CD), indicating alteration in gut microfloral metabolism. Data accumulated over recent decades by us and others suggest that wheat-free oats can safely be included in a gluten-free diet (GFD). However, concerns have been raised with respect to the safety of oats in a subset of coeliacs. AIM: To describe faecal SCFA patterns in children with newly diagnosed CD treated for 1 year with a GFD with or without oats. METHODS This report is part of a randomised, double-blind study on the effect of a GFD containing oats (GFD-oats) vs. a standard GFD (GFD-std). Faecal samples were received from 34 children in the GFD-oats group and 37 in the GFD-std group at initial diagnosis and/or after 1 year on a GFD. Faecal SCFAs were analysed. RESULTS The GFD-std group had a significantly lower total faecal SCFA concentration at 12 months compared with 0 months (P < 0.05). In contrast, total SCFA in the GFD-oats group remained high after 1 year on the GFD. The children in the GFD-oats group had significantly higher acetic acid (P < 0.05), n-butyric acid (P < 0.05) and total SCFA concentration (P < 0.01) after 1-year diet treatment compared to the GFD-std group. CONCLUSIONS Our results indicate that oats do affect the gut microflora function, and that some coeliac children receiving oats may develop gut mucosal inflammation, that may present a risk for future complications.
