Metabolomic Profiling

Metabolomic profiling using high resolution mass spectrometry with hydrophilic interaction chromatography was applied to 11 faecal extracts from eleven healthy children and to 43 faecal extracts from eleven children undergoing exclusive enteral nutrition for the treatment of active Crohn’s disease (CD) at timepoints before, during (15, 30, and 60 days), and after treatment. Differences between the control and CD samples were identified at each timepoint. An orthogonal partial least square-discriminant analysis (OPLS-DA) model identified eight metabolites that were normally distributed according to Q-Q plots. The OPLS-DA model was able to discriminate the CD samples from the controls at every timepoint, but the model was not able to differentiate the CD samples from one another at the different timepoints during treatment with exclusive enteral nutrition. The differentiated metabolites identified in the CD samples included tyrosine, an ornithine isomer, arachidonic acid, eicosatrienoic acid, docosatetraenoic acid, a sphingomyelin, a ceramide, and dimethylsphinganine. Despite successful treatment, underlying differences remained in the metabolome of the CD patients. These differences dominated the separation of the samples when multivariate methods were applied

Abstract Background Induction of clinical remission with exclusive enteral nutrition (EEN), has been associated with accompanying changes in the concentration of short chain fatty acids (SCFA) (a biomarker of fibre fermentation) in faeces of children with Crohn’s disease (CD) 1. Here, we assessed the fibre fermentative capacity of the gut microbiota of children with active CD in vitro, before, during and after EEN and compared with healthy children. Methods 44 faecal samples from 14 children (female, n=7, age, median [Q1, Q3]: 14.1 [11.1, 15.1] years) with active CD were collected before, during (4 weeks) and at the end of EEN (8 weeks) and after food reintroduction (median [Q1, Q3]: 21 [16, 31] days post-EEN). All children had achieved clinical remission at the end of EEN (weighted Paediatric Crohn’s Disease Activity Index <12.5). A single faecal sample was collected from 11 healthy children (female, n=4, age, median [Q1, Q3]: 12.4 [9.6, 13.0] years). 24-hour in vitro batch fermentations were performed using 4 fibre substrates (pectin, high-resistant maize starch, wheat bran and a mixture of the three). Net production of SCFA was measured with gas chromatography. Results Compared to healthy children, the total production of SCFA was significantly lower in children with CD, for all 4 fibre substrates, and regardless of the study timepoint (Figure 1). Net production of SCFA remained unchanged during EEN and at food reintroduction, and for all fibre substrates (Figure 1). No significant association with levels of faecal calprotectin was observed at any of the timepoints. Acetate production was significantly lower in children with CD compared to healthy children for all fibre substrates except for resistant maize starch (Figure 1). Likewise, except for pectin, production of butyrate was significantly lower in children with CD than healthy controls (Figure 1). Production of propionate did not significantly differ between any of the groups. Legend: Production of SCFA after 24-hour in vitro fermentation of faecal samples from CD and healthy children. Asterisks indicate significant differences. A: before EEN, B: 4-week EEN, C: End of EEN, D: Food reintroduction, HC: Healthy children Conclusion Fibre fermentative capacity is independent of disease activity in patients with CD and remains lower compared to healthy controls. It might be unlikely that the mechanism of action of EEN is mediated by modulation of fibre fermenting bacteria. Reference 1. Gerasimidis K, Bertz M, Hanske L, Junick J, Biskou O, Aguilera M, et al.

Therapy Strategies

The increase in incidences of pediatric Crohn’s Disease (CD) worldwide has been strongly linked with dietary shifts towards a Westernized diet, ultimately leading to altered gut microbiota and disturbance in intestinal immunity and the metabolome. Multiple clinical studies in children with CD have demonstrated the high efficacy of nutritional therapy with exclusive enteral nutrition (EEN) to induce remission with an excellent safety profile. However, EEN is poorly tolerated, limiting its compliance and clinical application. This has spiked an interest in the development of alternative and better-tolerated nutritional therapy strategies. Several nutritional therapies have now been designed not only to treat the nutritional deficiencies seen in children with active CD but also to correct dysbiosis and reduce intestinal inflammation. In this review, we report the most recent insights regarding nutritional strategies in children with active CD: EEN, partial enteral nutrition (PEN), Crohn’s disease exclusion diet (CDED), and CD treatment-with-eating diet (CD-TREAT). We describe their setup, efficacy, safety, and (dis)advantages as well as some of their potential mechanisms of action and perspectives. A better understanding of different nutritional therapeutic options and their mechanisms will yield better and safer management strategies for children with CD and may address the barriers and limitations of current strategies in children.
