The incidence of inflammatory bowel disease (IBD) is steadily in the rise in Western as well as in developing countries paralleling the increase of westernized diets, characterized by high protein and fat as well as excessive sugar intake, with less vegetables and fiber. An interesting hypothesis is that environmental (food-) triggered changes of the intestinal microbiome might cause a proinflammatory state preceding the development of IBD. Indeed, an intact intestinal epithelial barrier assuring a normal bacterial clearance of the intestinal surface is crucial to guarantee intestinal homeostasis. Any factors affecting the epithelial barrier function directly or indirectly may impact on this homeostasis, as well as any changes of the intestinal microbial composition. It is intriguing to learn that some frequently used food components impact on the quality of the intestinal barrier, as well as on the composition of the intestinal microbiome. This highlights the close interaction between living conditions, hygiene, food habits and food quality with the bacterial composition of the intestinal microbiome and the activation status of the intestinal immune system. There is clear evidence that nutritional therapy is highly successful in the treatment of Crohn's disease (CD). Exclusive enteral nutrition is well established as induction therapy of CD. New diets, such as a CD exclusion diet or defined diets (specific carbohydrate diets, FODMAP diet, Paleolithic diet) are being discussed as treatment options for IBD. Well-designed clinical trials in IBD are urgently required to define the precise role of each of these diets in the prevention or management of IBD. Up to now, the role of diet in IBD is highly undermined by lay and anecdotal reports without sufficient scientific proof.

Diet is a key modifier of risk of inflammatory bowel disease development and potentially a treatment option in patients with established disease. International organisations in gastroenterology and inflammatory bowel disease have published guidelines for the role of diet in disease onset and its management. Here, we discuss the major overarching themes arising from these guidelines and appraise recent literature on the role of diet for inflammatory bowel disease prevention, treatment of active disease and maintenance of remission, considering these themes. Except for exclusive enteral nutrition in active Crohn’s disease, we currently possess very little evidence to make any further dietary recommendations for the management of inflammatory bowel disease. There is also currently uncertainty on the extrapolation of epidemiological dietary signals on risk of disease development and preclinical experiments in animal models to management, once disease is established. Until high-quality evidence from clinical research becomes available, the only specific recommendations for inflammatory bowel disease we might safely give are those of healthy eating which apply for the general population for overall health and well-being.

Abstract The nutritional developmental origins of inflammatory bowel disease[s] (IBDs: Crohn’s disease or Crohn disease [CD] and ulcerative colitis [UC]) and their diet-based treatments continue to receive increasing attention. There is growing evidence for the success of nutrition-based treatments, such as exclusive enteral nutrition [EEN] and the specific carbohydrate diet [SCD], in both paediatric and adult patients. Beyond these two dietary interventions, symptomatic benefit in IBD has also been shown from a gluten-free diet [GFD] and paleolithic diet [PALEO], among others. These nutritional therapies may point to critical factors in not only the pathology, but also the pathogenesis of the disease group. It is difficult, however, to discern a common element within the large number of diet-based causation theories [e.g. emulsifiers, processed foods, refrigeration, increased total fat intake, low fibre intake, carbohydrate dominant food, etc.] and the varied dietary treatments of IBD. This Viewpoint article highlights that carbohydrate variation links diet-based causation theories, and that carbohydrate monotony or persistence is the commonly shared characteristic of diet-based IBD therapy. Further research directed towards carbohydrate monotony may critically advance the prevention and treatment of these highly morbid conditions.

And Function

Inflammatory bowel disease (IBD) is a chronic, autoimmune disorder of the gastrointestinal tract with numerous genetic and environmental risk factors. Patients with Crohn’s disease (CD) or ulcerative colitis (UC) often demonstrate marked disruptions of their gut microbiome. The intestinal microbiota is strongly influenced by diet. The association between the increasing incidence of IBD worldwide and increased consumption of a westernized diet suggests host nutrition may influence the progression or treatment of IBD via the microbiome. Several nutritional therapies have been studied for the treatment of CD and UC. While their mechanisms of action are only partially understood, existing studies do suggest that diet-driven changes in microbial composition and function underlie the diverse mechanisms of nutritional therapy. Despite existing therapies for IBD focusing heavily on immune suppression, nutrition is an important treatment option due to its superior safety profile, potentially low cost, and benefits for growth and development. These benefits are increasingly important to patients. In this review, we will describe the clinical efficacy of the different nutritional therapies that have been described for the treatment of CD and UC. We will also describe the effects of each nutritional therapy on the gut microbiome and summarize the strength of the literature with recommendations for the practicing clinician.

ABSTRACT Background and Aims : Mouse and human data implicates the NOD1 and NOD2 sensors of the intestinal microbiome and the associated signal transduction via the RIPK2 kinase as a potentially key signaling node for the development of Inflammatory Bowel Disease (IBD) and an attractive target for pharmacologic intervention. The TRUC mouse model of IBD has been strongly indicated for evaluating the impact of RIPK2 antagonism on intestinal inflammation based on previous studies with NOD1, NOD2 and RIPK2 knockout mice. Methods. We identified and profiled the BI 706039 molecule as a potent and specific functional inhibitor of both human and mouse RIPK2 and with favorable pharmacokinetic properties. We dosed BI 706039 in the spontaneous TRUC mouse model from aged day 28 through aged day 56. Results : Oral, daily administration of BI 706039 caused dose-responsive and significant improvement in colonic histopathological inflammation, colon weight and terminal levels of protein normalized fecal lipocalin (all p< 0.001). These observations correlated with dose-responsively increasing systemic levels of the BI 706039 compound, splenic molecular target engagement of RIPK2 and modulation of inflammatory genes in the colon. Conclusions : A relatively low oral dose of a potent and selective RIPK2 inhibitor can block the signaling interface between the intestinal microbiome and the intestinal immune system and significantly improve disease associated intestinal inflammation.

Main Factors

Inflammatory bowel disease (IBD), including Crohn’s disease and ulcerative colitis, are chronic, relapsing intestinal inflammatory disorders. Although the molecular mechanisms governing the pathogenesis of IBD are not completely clear, the main factors are presumed to be a complex interaction between genetic predisposition, host immune response and environmental exposure, especially the intestinal microbiome. Currently, most studies have focused on the role of gut bacteria in the onset and development of IBD, whereas little attention has been paid to the enteroviruses. Among of them, viruses that infect prokaryotes, called bacteriophages (phages) occupy the majority (90%) in population. Moreover, several recent studies have reported the capability of regulating the bacterial population in the gut, and the direct and indirect influence on host immune response. The present review highlights the roles of gut phages in IBD pathogenesis and explores the potentiality of phages as a therapeutic target for IBD treatment.

Inflammatory Bowel

Aetiology of inflammatory bowel disease (IBD) is complex and probably multifactorial. Nutrition has been proposed to be an important aetiological factor for development of IBD. Several components of the diet (such as sugar, fat, fibre, fruit and vegetable, protein, fast food, preservatives etc.) were examined as possible causative agents for IBD. According to some researchers infant feeding (breast feeding) may also contribute to the development of IBD. Though the importance of environmental factors is evidenced by the increasing incidence in developed countries and in migrant population in recent decades, the aetiology of IBD remained unclear. There are many theories, but as yet no dietary approaches have been proved to reduce the risk of developing IBD. The role of nutrition in the management of IBD is better understood. The prevention and correction of malnutrition, the provision of macro- and micronutrients and vitamins and the promotion of optimal growth and development of children are key points of nutritional therapy. In active disease, the effective support of energy and nutrients is a very important part of the therapy. Natural and artificial nutrition or the combination of two can be choosen for supporting therapy of IBD. The author summarises the aetiological and therapeutic role of nutrition in IBD.
