Abstract
As the treatment of inflammatory bowel disease (IBD) becomes more complex and increasingly relies on combinations of immunosuppression in patients with moderate to severe ulcerative colitis or Crohn's disease, the provider must be aware of recommendations for the appropriate use of vaccines-both inactivated and live. The timing and type of vaccination required may be altered based on the underlying medical treatment for the IBD. In some instances, titers may be required to assess for vaccine response. Vaccination recommendations have changed dramatically over the past 5 years with direct implications for the protection of the patients with IBD. There are several newly licensed vaccines and new recommendations by the U.S. Advisory Committee on Immunization Practices and Infectious Diseases Society of America defining degrees of immunosuppression and the use of certain live vaccines based on these levels. This review provides a case-based approach to vaccinating the pediatric and adult patients with IBD, with an emphasis on practicality. Case scenarios include children and adults with newly diagnosed and chronic IBD. Recommendations for vaccine management in these scenarios are provided, including special circumstances such as pregnancy and infant vaccinations when the mother is receiving immunosuppressive medication.

The Protective Effects of Exclusive Enteral Nutrition Formulas on Growth Factor Expression and the Proximal Tibial Epiphyseal Growth Plate in a TNBS-Induced IBD Rat Model. Dig Dis Sci 2015; 60:1931-40. [PMID: 25708898 DOI: 10.1007/s10620-015-3582-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2014] [Accepted: 02/05/2015] [Indexed: 12/23/2022]
Abstract
OBJECTIVE This study aimed to evaluate the effectiveness of different types of nutritional formulas in a rat model of TNBS-induced IBD. METHODS IBD was induced with TNBS in 4-week-old rats that were then fed different exclusive enteral nutrition diets for 7 days. The length of the tibia and the number of chondrocytes in the proximal tibias were analyzed at 7 days after supplementation. Immunohistochemical analysis, ELISA and real-time PCR were performed to evaluate the levels of growth hormone receptor (GHR) and insulin-like growth factor-I receptor (IGF-IR), the growth factors IGF-I and insulin-like growth factor-binding protein-3 (IGFBP3) , bone morphogenetic protein (BMP)-2 and BMP-6 respectively. RESULTS The results demonstrated that the tibia length of the peptide formula group was longer than that of the IBD-Modulen(®) formula and normal diet groups (P < 0.05). Furthermore, the number of chondrocytes of the proximal tibial was more pronounced in the peptide formula group compared to the other groups (P < 0.05). The peptide formula was also more effective in increasing the expression of GHR compared to the other groups (P < 0.05), while the expression of IGF-IR was not significantly different (P > 0.05). In addition, the IGF-I and IGFBP3 levels were more pronounced in the peptide formula supplement group (P < 0.05), and the expression of BMP-2 and BMP-6 mRNA in the proximal tibia growth plate from the peptide formula group was higher than that in the ordinary formula and normal diet groups (P < 0.05). CONCLUSIONS EEN, and particularly a peptide formula, exerted protective effects on the proximal tibial epiphyseal growth plate in a TNBS-induced IBD model.

Abstract
Exclusive enteral nutrition involves the use of a complete liquid diet, with the exclusion of normal dietary components for a defined period of time, as a therapeutic measure to induce remission in active Crohn's disease (CD). This very efficacious approach leads to high rates of remission, especially in children and adolescents newly diagnosed with CD. This intervention also results in mucosal healing, nutritional improvements and enhanced bone health. Whilst several recent studies have provided further elaboration of the roles of exclusive enteral nutrition in the management of CD, other reports have provided new understanding of the mechanisms by which this intervention acts.

Abstract
The sodium/glucose cotransporter 1 (SGLT1) is responsible for glucose uptake in intestinal epithelial cells. Its expression is decreased in individuals with intestinal inflammatory disorders and is correlated with the pathogenesis of disease. The aim of this study was to understand the regulatory mechanism of the SGLT1 gene. Using the trinitrobenzene sulfonic acid-induced mouse models of intestinal inflammation, we observed decreased SGLT1 expression in the inflamed intestine was positively correlated with the mucosal level of epidermal growth factor (EGF) and activated CREB. Overexpression of EGF demonstrated that the effect of EGF on intestinal glucose uptake was primarily due to the increased level of SGLT1. We identified an essential cAMP binding element (CRE) confers EGF inducibility in the human SGLT1 gene promoter. ChIP assay further demonstrated the increased binding of CREB and CBP to the SGLT1 gene promoter in EGF-treated cells. In addition, the EGFR- and PI3K-dependent CREB phosphorylations are involved in the EGF-mediated SGLT1 expression. This is the first report to demonstrate that CREB is involved in EGF-mediated transcription regulation of SGLT1 gene in the normal and inflamed intestine, which can provide potential therapeutic applications for intestinal inflammatory disorders.

Abstract
BACKGROUND Long-term effectiveness of enteral nutrition for maintaining remission in pediatric Crohn's disease (CD) is poorly documented. The aim of this study was therefore to examine the long-term effectiveness of enteral nutrition with aminosalicylates as maintenance therapy for those in whom remission was primarily induced by total parenteral nutrition or exclusive enteral nutrition with aminosalicylates. METHODS We retrospectively analyzed data for 58 pediatric patients with newly diagnosed CD during a median follow-up period of 50 months (range, 12-216 months). Data for remission-induced patients in whom enteral nutrition with aminosalicylates was used as maintenance therapy were analyzed with particular reference to time to first relapse and time to first intestinal surgery. RESULTS Twenty-five (43.1%) of the patients relapsed with a median duration of remission of 32.4 months (range, 6-73.2 months). The cumulative rates of continuous remission were 0.88 (95%CI: 0.79-0.96) at 1 year, 0.73 (95%CI: 0.61-0.85) at 2 years, and 0.52 (95%CI: 0.35-0.68) at 5 years. None of the patients received corticosteroids, immunomodulators or anti-tumor necrosis factor agents until relapse. Disease location had no impact on timing of relapse, but with regard to disease behavior there was a trend towards earlier relapse in patients with penetrating type. Only six of the 58 patients (10.3%) needed intestinal surgery. There was a trend towards need for surgery in patients with ileal disease and with stricturing type. CONCLUSIONS Enteral nutrition therapy with aminosalicylates is effective for maintaining remission and decreasing the rate of intestinal surgery in pediatric CD.

Abstract
Crohn disease (CD) and ulcerative colitis (UC), the two main types of inflammatory bowel disease (IBD), have become increasingly common in Australasian children and adolescents in recent years. Furthermore, CD and UC are seen more often in younger children. These conditions are typically more extensive in children and tend to follow more severe disease courses than in adults. Although many children may present with typical symptoms (such as abdominal pain or bloody diarrhoea), others have atypical features (including oral ulceration, short stature or skin manifestations). In addition, many children with IBD will have altered growth or nutrition, which may compromise normal linear growth and pubertal development. Early identification and full assessment of children presenting with possible IBD are essential to avoid consequences of diagnostic delay and to optimise short- and long-term outcomes. Management of IBD encompasses various options and should be undertaken within a team-based, child and family-focused, multidisciplinary setting.

Abstract
OBJECTIVES Exclusive enteral nutrition (EEN) is commonly used to treat pediatric Crohn's disease (CD). Meta-analysis of pediatric studies that have compared the effect of EEN with other treatments have shown that EEN induces remission in up to 80-85% of patients. We aimed to gain a comprehensive understanding of the effect of EEN on the microbiota of CD patients. METHODS We used 16S rRNA gene and whole-genome high throughout sequencing to determine changes in the fecal microbiota of five CD children, before, during, and after EEN therapy and compared this with five healthy controls. RESULTS The microbial diversity observed in CD patients tended to be lower than that in controls (CD: 2.25±0.24, controls: 2.75±0.14, P=0.11). In all CD patients, dysbiosis was observed prior to therapy. EEN therapy had a positive effect in all patients, with 80% going into remission. In some patients, the positive effect diminished following the conclusion of EEN therapy. Significantly, the number of operational taxonomic units (OTU) decreased dramatically upon starting EEN and this corresponded with CD remission. Recurrence of CD corresponded with an increase in OTUs. Six families within the Firmicutes were found to correlate with disease activity during and following EEN therapy, a finding that was confirmed by whole-genome high throughput sequencing. CONCLUSIONS Our results demonstrate that EEN leads to common and patient-specific alterations in the microbiota of CD patients, a number of which correlate with disease activity.

Abstract
In assessing the best evidence for optimizing management of inflammatory bowel disease (IBD), the focus is typically on anti-inflammatory agents and therapies that modulate the immune system. The intestinal immune response remains the key focus of developing therapies as well. In the past decade, the concept of dysbiosis of the gut microbiome has emerged as a potential pathogenetic focus in IBD, and with this a burgeoning interest in manipulating the microbiome as a means of controlling the disease has emerged. In this review, anti-inflammatory, immune-modulating, and microbiome-modulating therapies will be covered in terms of what is known today, as well as treatments that may be part of the therapeutic armamentarium in the near future. Concurrent with the evolution of our understanding of the basic biology of IBD, there is an increasing appreciation for the disconnect between patients' symptoms and inflammatory disease. As clinical trials have simultaneously addressed both symptom scores and mucosal healing, investigators and clinicians have gained a greater appreciation for the fact that many symptoms may not be driven by active inflammation, and hence focusing only on immunomodulatory therapies would not serve patients' needs fully. Furthermore, there is an emerging recognition of the importance of stress and psychological health in symptom experience and treatment needs. In this review, approaches to managing patients' symptoms as well as other adjunctive approaches to improving well-being will also be discussed. Finally, throughout this review, important research questions regarding different aspects of treatment will be proposed.

Abstract
One of the most effective forms of therapeutic enteral nutrition is designated as “exclusive enteral nutrition” (EEN). EEN constitutes the monotonous enteral delivery of complete liquid nutrition and has been most explored in the treatment Crohn’s disease (CD), a form of inflammatory bowel disease. While EEN’s mechanisms of action are not clearly understood, it has been shown to modify the composition of the intestinal microbiome, an important component of CD pathogenesis. The current literature on the intestinal microbiome in healthy individuals and CD patients is reviewed with respect to EEN therapy. Further investigations in this field are needed to better understand the role and potential for EEN in chronic human disorders.

Abstract
GOALS To examine the efficiency of exclusive enteral nutrition (EEN) in relieving inflammatory bowel stricture in patients with Crohn's disease (CD). BACKGROUND Patients with CD usually develop bowel strictures due to transmural edema of intestinal wall, which can potentially be managed with conservative medical treatment. Previous studies showed that EEN therapy could induce clinical remission through its anti-inflammation effect. METHODS We achieved a prospective observational study. CD patients with inflammatory bowel stricture were preliminarily differentiated from a fibrous one, and further treated with EEN therapy for 12 weeks. Demographics and clinical variables were recorded. Nutritional (body mass index, albumin, pre-albumin, transferrin, etc.), inflammatory (C-reactive protein, erythrocyte sedimentation rate, white blood cell, etc.), and radiologic parameters (bowel wall thickness, luminal diameter, and luminal cross-sectional area) were evaluated at baseline, week 4, and week 12, respectively. RESULTS Between May 2012 and January 2013, 65 patients with CD were preliminarily diagnosed with inflammatory bowel stricture and 6 patients were further excluded. Among the remaining 59 cases, 50 patients (84.7%) finished the whole EEN treatment, whereas the other 9 patients (15.3%) gained progressive bowel obstruction resulting in surgery. Intention-to-treat analyses showed that 48 patients (81.4%) achieved symptomatic remission, 35 patients (53.8%) achieved radiologic remission, and 42 patients (64.6%) achieved clinical remission. Among those patients who complete the whole EEN therapy, inflammatory, nutritional, and radiologic parameters improved significantly compared with baseline. Of note, the average luminal cross-sectional area at the site of stricture increased approximately 331% at week 12 (195.7 ± 18.79 vs. 59.09 ± 10.64 mm, P<0.001). CONCLUSIONS EEN therapy can effectively relieve inflammatory bowel stricture in CD, which replenishes roles of enteral nutrition in the treatment of CD. Further studies are expected to investigate the underlying mechanisms of this effect in the future.

Abstract
Children and adolescents with Crohn's disease (CD) present often with a more complicated disease course compared to adult patients. In addition, the potential impact of CD on growth, pubertal and emotional development of patients underlines the need for a specific management strategy of pediatric-onset CD. To develop the first evidenced based and consensus driven guidelines for pediatric-onset CD an expert panel of 33 IBD specialists was formed after an open call within the European Crohn's and Colitis Organisation and the European Society of Pediatric Gastroenterolog, Hepatology and Nutrition. The aim was to base on a thorough review of existing evidence a state of the art guidance on the medical treatment and long term management of children and adolescents with CD, with individualized treatment algorithms based on a benefit-risk analysis according to different clinical scenarios. In children and adolescents who did not have finished their growth, exclusive enteral nutrition (EEN) is the induction therapy of first choice due to its excellent safety profile, preferable over corticosteroids, which are equipotential to induce remission. The majority of patients with pediatric-onset CD require immunomodulator based maintenance therapy. The experts discuss several factors potentially predictive for poor disease outcome (such as severe perianal fistulizing disease, severe stricturing/penetrating disease, severe growth retardation, panenteric disease, persistent severe disease despite adequate induction therapy), which may incite to an anti-TNF-based top down approach. These guidelines are intended to give practical (whenever possible evidence-based) answers to (pediatric) gastroenterologists who take care of children and adolescents with CD; they are not meant to be a rule or legal standard, since many different clinical scenario exist requiring treatment strategies not covered by or different from these guidelines.

Abstract
BACKGROUND Health care decision-makers have begun to realize that medical nutrition plays an important role in the delivery of care, and it needs to be seen as a sole category within the overall health care reimbursement system to establish the value for money. Indeed, improving health through improving patients' nutrition may contribute to the cost-effectiveness and financial sustainability of health care systems. Medical nutrition is regulated by a specific bill either in Europe or in the United States, which offers specific legislations and guidelines (as provided to patients with special nutritional needs) and indications for nutritional support. Given that the efficacy of medical nutrition has been proven, one can wonder whether the heterogeneous nature of its coverage/reimbursement across countries might be due to the lack of health-related economic evidence or value-for-money of nutritional interventions. This paper aims to address this knowledge gap by performing a systematic literature review on health economics evidence regarding medical nutrition, and by summarizing the results of these publications related to the value for money of medical nutrition interventions. METHODS A systematic literature search was initiated and executed based on a predefined search protocol following the population, intervention, comparison, and outcomes (PICO) criteria. Following the systematic literature search of recently published literature on health economics evidence regarding medical nutrition, this study aims to summarize the results of those publications that are related to the value for money of medical nutrition interventions. The evaluations were conducted by analyzing different medical nutrition according to their indications, the economic methodology or perspective adopted, the cost source and utility measures, selected efficiency measures, as well as the incremental cost-effectiveness ratio. RESULTS A total of 225 abstracts were identified for the detailed review, and the data were entered into a data extraction sheet. For the abstracts that finally met the predefined inclusion criteria (n=53), full-text publications were obtained via PubMed, subito, or directly via each journal's Webpage for further assessment. After a detailed review of the full text articles, 34 publications have been qualified for a thorough data extraction procedure. When differentiating the resulting articles in terms of their settings, 20 studies covered inpatients, whereas 14 articles covered outpatients, including patients in community centers. When reviewing the value-for-money evaluations, the indications showed that the different results were mostly impacted by the different perspectives adopted and the comparisons that were made. In order to draw comprehensive conclusions, the results were split according to the main indications and diseases. DISCUSSION The systematic literature search has shown that there is not only an interest in health economics and its application in medical nutrition, but that there is a lot of ongoing research in this area. Based on the underlying systematic analysis, it has been shown that medical nutrition interventions offer value for money in the different health care settings, particularly for the specific disease areas that have been pointed out. CONCLUSION Based on the systematic literature search that was performed, it was shown that medical nutrition interventions offer value for money in the different health care settings. Although medical nutrition has been the topic of some health economic analyses, the usual willingness to pay threshold used in health care rarely was applied. Often, these products are either directly part of a lump sum in the financing system (for example, diagnosis-related groups), or they are covered as out-of-pocket payments by patients directly. More research would be necessary to better understand how medical nutrition interventions can be optimally funded by the health care system, given the clinical value they bring to patients in their recovery process.

Standard versus rapid food reintroduction after exclusive enteral nutritional therapy in paediatric Crohn's disease. Eur J Gastroenterol Hepatol 2014; 26:276-81.

Abstract
BACKGROUND In paediatric Crohn's disease (PCD), 6-8 weeks of exclusive enteral nutrition (EEN) is effective in 60-80% cases. EEN is followed by gradual food reintroduction over variable (1-5 weeks) periods. Currently, there is no recommended duration or method for food reintroduction. The rationale for slow reintroduction is unclear and may be because of concerns about food intolerance or to maintain longer remission. AIMS The aims of this study were as follows: to compare relapse rates following standard and rapid reintroduction of food after EEN in PCD and to determine the duration of maintained remission in two groups of PCD patients. MATERIALS AND METHODS Two groups with PCD were compared: group A received standard food reintroduction over 5 weeks and group B received rapid reintroduction over 3 days. Data were collected over two consecutive time periods: group A (2005-2009) and group B (2009-2011). Only patients with a new diagnosis of PCD were included. Those with strictures and those on steroids or biologicals during EEN were excluded. The minimum duration of follow-up was 1 year. RESULTS Group A included 20 patients and group B included 19 patients. In these groups, EEN led to clinical remission in 80% of the patients in group A and in 76% of the patients in group B. At 6 months, one-third of the patients from each group had developed relapse and a year after EEN, 50% of the patients in group A and 47% of the patients in group B developed relapse. Time to first relapse was 188 days (group A) and 136 days (group B). None of these results were statistically significant. CONCLUSION In PCD, rapid food reintroduction following 6-week EEN is safe and equally effective as longer food reintroduction. We propose that a rapid food reintroduction schedule be recommended as the most tolerable approach for food reintroduction. Relapse rate and duration of remission are uninfluenced by the type of food reintroduction.

Abstract
BACKGROUND Robust evaluation of induction therapies using both clinical and inflammatory outcomes in pediatric Crohn's disease (CD) are sparse. We attempted to evaluate clinical, inflammatory, and composite outcomes of induction of remission therapies (normal C reactive protein [CRP] remission) in a large pediatric prospective multicenter study. METHODS Patients enrolled at diagnosis into the growth relapse and outcomes with therapy in Crohn's disease study were evaluated for disease activity, CRP, and fecal calprotectin at 8, 12 and 52 weeks after starting treatment. The primary endpoint was week-12 steroid-free remission defined by pediatric Crohn's disease activity index and CRP <0.5 mg/dL. The protocol required tapering off corticosteroids by week 11. RESULTS We analyzed 222 patients (mean age, 12.9 ± 3.2 yr) main evaluated treatment options included: 5-ASA (n = 29), exclusive enteral nutrition (n = 43), and corticosteroids (n = 114). Clinical remission at week 12 was achieved in 155 (73%) patients; both exclusive enteral nutrition and steroids were associated with normal CRP remission at week 12, although in a post hoc subgroup analysis exclusive enteral nutrition was superior in mild-to-moderate disease for this outcome. Among those in steroid-free remission in week 12, normal CRP predicted 1-year sustained remission (86% for normal CRP versus 61% for elevated CRP; P = 0.02). Baseline severity and early immunomodulation were similar in both groups. CONCLUSIONS Normal CRP steroid-free remission at week 12 was impacted by type of induction therapy, but not by early immunomodulation. It was associated with more corticosteroids-free remission at week 52 and a trend for less relapses.

Abstract
UNLABELLED Paediatric inflammatory bowel disease (IBD), especially Crohn's disease (CD), is commonly associated with poor skeletal health, related to the direct effects of chronic inflammation, prolonged use of glucocorticoid (GC), poor nutrition, delayed puberty and low muscle mass. Low bone mineral density is commonly reported, although the prevalence of long bone fractures may not be increased in these patients. Emerging evidence however suggests that there may be an increased risk of vertebral fractures (VFs) in this group. VFs presenting at diagnosis of paediatric CD, prior to any GC exposure, have been reported, highlighting the deleterious effect of inflammation on skeletal health. This paper reviews the published literature on pathophysiology of skeletal morbidity and fractures in paediatric IBD, illustrated with a new case report of multiple VFs in a prepubertal girl with CD, soon after diagnosis, who received minimal amounts of oral GC. Optimising control of disease, addressing vitamin D deficiency, encouraging physical activity and ensuring normal growth and pubertal progression are paramount to management of bone health in these patients. Despite the lack of evidence, there may be a place for bisphosphonate treatment, especially in the presence of symptomatic pathological fractures, but this requires close monitoring by clinicians with expertise in paediatric bone health. CONCLUSION Chronic inflammation mediated by pro-inflammatory cytokines may have adverse effects on skeletal health in paediatric patients with IBD. The risk of vertebral fractures may be increased, even without exposure to glucocorticoid. Clinical monitoring of these patients requires careful attention to the various factors that impact on bone health.

Abstract
Increasing numbers of adolescents are being diagnosed with Crohn's disease or ulcerative colitis, the two main subtypes of inflammatory bowel disease. These young people face many short- and long-term challenges; one or more medical therapies may be required indefinitely; their disease may have great impact, in terms of their schooling and social activities. However, the management of adolescents with one of these incurable conditions needs to encompass more than just medical therapies. Growth, pubertal development, schooling, transition, adherence, and psychological well-being are all important aspects. A multidisciplinary team setting, catering to these components of care, is required to ensure optimal outcomes in adolescents with inflammatory bowel disease.

Abstract
Exclusive enteral nutrition (EEN) is well-established as a first line therapy instead of corticosteroid (CS) therapy to treat active Crohn's disease (CD) in children. It also has been shown to have benefits over and above induction of disease remission in paediatric populations. However, other than in Japanese populations, this intervention is not routinely utilised in adults. To investigate potential reasons for variation in response between adult studies of EEN and CS therapy. The Ovid database was searched over a 6-mo period. Articles directly comparing EEN and CS therapy in adults were included. Eleven articles were identified. EEN therapy remission rates varied considerably. Poor compliance with EEN therapy due to unpalatable formula was an issue in half of the studies. Remission rates of studies that only included patients with previously untreated/new CD were higher than studies including patients with both existing and new disease. There was limited evidence to determine if disease location, duration of disease or age of diagnosis affected EEN therapy outcomes. There is some evidence to support the use of EEN as a treatment option for a select group of adults, namely those motivated to adhere to an EEN regimen and possibly those newly diagnosed with CD. In addition, the use of more palatable formulas could improve treatment compliance.

Abstract
UNLABELLED BACKGROUND⁄ OBJECTIVES The relationship between the enteroendocrine hormone glucagon-like peptide 2 (GLP-2) and intestinal inflammation is unclear. GLP-2 promotes mucosal growth, decreases permeability and reduces inflammation in the intestine; physiological stimulation of GLP-2 release is triggered by nutrient contact. The authors hypothesized that ileal Crohn disease (CD) affects GLP-2 release. METHODS With ethics board approval, pediatric patients hospitalized with CD were studied; controls were recruited from local schools. Inclusion criteria were endoscopy-confirmed CD (primarily of the small intestine) with a disease activity index >150. Fasting and postprandial GLP-2 levels and quantitative urinary recovery of orally administered 3-O-methyl-glucose (active transport) and lactulose⁄mannitol (passive) were quantified during the acute and remission phases. RESULTS Seven patients (mean [± SD] age 15.3 ± 1.3 years) and 10 controls (10.3 ± 1.6 years) were studied. In patients with active disease, fasting levels of GLP-2 remained stable but postprandial levels were reduced. Patients with active disease exhibited reduced glucose absorption and increased lactulose⁄mannitol recovery; all normalized with disease remission. The change in the lactulose⁄mannitol ratio was due to both reduced lactulose and increased mannitol absorption. CONCLUSIONS These findings suggest that pediatric patients with acute ileal CD have decreased postprandial GLP-2 release, reduced glucose absorption and increased intestinal permeability. Healing of CD resulted in normalization of postprandial GLP-2 release and mucosal functioning (nutrient absorption and permeability), the latter due to an increase in mucosal surface area. These findings have implications for the use of GLP-2 and feeding strategies as a therapy in CD patients; further studies of the effects of inflammation and the GLP-2 axis are recommended.

Abstract
Crohn's disease is a complex inherited disorder of unknown pathogenesis with environmental, genetic, and microbial factors involved in the development of the disease. A remarkable feature of this disease, especially, but not limited to childhood, is the effective response to exclusive enteral nutrition therapy and the observed benefit from exclusion of normal diet (principle of exclusivity). We reviewed the possible mechanisms of action of enteral nutrition for induction of remission and provided a hypothetical model (herein termed bacterial penetration cycle) that integrates dietary components, bacteria, susceptibility genes, and the innate immune response in the pathogenesis of Crohn's disease.

Abstract
OBJECTIVES Multiple characteristics of industrialization have been proposed to contribute to the global emergence of inflammatory bowel diseases (IBDs: Crohn disease and ulcerative colitis). Major changes in eating habits during the last decades and the effectiveness of exclusive enteral nutrition in the treatment of Crohn disease indicate the etiologic importance of dietary intake in IBDs. A uniform characteristic of nutrition in developing countries (where the incidence of IBD is low) and exclusive enteral nutrition is their consistent nature for prolonged periods; however, the potentially beneficial effect of dietary monotony in respect to mammalian intestinal inflammation has not been examined. METHODS The association between alternating (2 different complete chows) and persistent regular diets, and dextran sulfate sodium colitis susceptibility in C57BL/6J mice was studied. Colonic mucosal microbiota changes were investigated by high-throughput pyrosequencing of the 16S rRNA gene. RESULTS The severity of colitis increased upon dietary alternation compared with consistent control feeding. The microbiota of the alternating nutritional group clustered discretely from both control groups. CONCLUSIONS Our findings highlight that monotonous dietary intake may decrease mammalian vulnerability against colitis in association with microbiota separation. The epidemiologic and therapeutic implications of our results are also discussed.

Abstract
Exclusive enteral nutrition is an effective therapy for the management of active Crohn's disease, especially in children and adolescents. This therapeutic approach involves the use of a liquid nutritional product with the exclusion of normal diet for a period of many weeks. Although recent studies have helped to delineate some aspects of how exclusive enteral nutrition should be used, there remain many gaps in our understanding. In addition, several recent reports have provided intriguing insights into the mechanisms of this nutritional approach.

Abstract
OBJECTIVE Exclusive enteral nutrition (EEN) is a first-line treatment in children with active Crohn's disease (CD) but is seldom used in adults with active disease. The mode of action of EEN in suppressing mucosal inflammation is not fully understood, but modulation of intestinal microflora activity is one possible explanation. The aim of this study was to investigate the effect of 6-week EEN in children with active CD, with special reference to intestinal microflora function. MATERIALS AND METHODS Fecal samples from 18 children (11 boys, 7 girls; median age 13.5 years) with active CD (13 children with small bowel/colonic and 5 with perianal disease) were analyzed for short chain fatty acid (SCFA) pattern as marker of gut microflora function. The children were studied before and after EEN treatment. Results from 12 healthy teenagers were used for comparison. RESULTS Eleven (79%) of the children with small bowel/colonic CD responded clinically positively to EEN treatment showing decreased levels of pro-inflammatory acetic acid as well as increased concentrations of anti-inflammatory butyric acids and also of valeric acids, similar to the levels in healthy age-matched children. In children with active perianal CD, however, EEN had no positive effect on clinical status or inflammatory parameters. CONCLUSIONS The authors present new data supporting the hypothesis that the well-documented anti-inflammatory effect of EEN in children with active small bowel/colonic CD is brought about by modulation of gut microflora activity, resulting in an anti-inflammatory SCFA pattern. By contrast, none of the children with perianal disease showed clinical or biochemical improvement after EEN treatment.

Abstract
Crohn's disease and ulcerative colitis can be grouped as the inflammatory bowel diseases (IBD). These conditions have become increasingly common in recent years, including in children and young people. Although much is known about aspects of the pathogenesis of these diseases, the precise aetiology is not yet understood, and there remains no cure. Recent data has illustrated the importance of a number of genes-several of these are important in the onset of IBD in early life, including in infancy. Pain, diarrhoea and weight loss are typical symptoms of paediatric Crohn's disease whereas bloody diarrhoea is more typical of colitis in children. However, atypical symptoms may occur in both conditions: these include isolated impairment of linear growth or presentation with extra-intestinal manifestations such as erythema nodosum. Growth and nutrition are commonly compromised at diagnosis in both Crohn's disease and colitis. Consideration of possible IBD and completion of appropriate investigations are essential to ensure prompt diagnosis, thereby avoiding the consequences of diagnostic delay. Patterns of disease including location and progression of IBD in childhood differ substantially from adult-onset disease. Various treatment options are available for children and adolescents with IBD. Exclusive enteral nutrition plays a central role in the induction of remission of active Crohn's disease. Medical and surgical therapies need to considered within the context of a growing and developing child. The overall management of these chronic conditions in children should include multi-disciplinary expertise, with focus upon maintaining control of gut inflammation, optimising nutrition, growth and quality of life, whilst preventing disease or treatment-related complications.
