Inflammatory Bowel

A significant overlap exists between spondyloarthritis (SpA) and inflammatory bowel disease (IBD), particularly in the IL-23/IL-17 pathway. Shared immunologic mechanisms include aberrant innate immune responses, an excess of Th1/Th17-mediated immunity, and inadequate immune regulation. Many genetic factors associated with IBD are involved in host–pathogen interactions and intestinal barrier function, and the intestinal microbiota do appear to play an important role in disease development. Hence the current hypothesis for IBD pathogenesis is that it stems from a dysregulated immune response to intestinal microbiota in a genetically susceptible host. In SpA, evidence for a role of intestinal microbiota is less abundant, but given the overlap with IBD, it is plausible that gut microbiota are important players in SpA pathogenesis as well. However, there are significant genetic differences between these two conditions, as well as differing responses to biologic therapy.

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.

Abstract Background and aims The association between smoking and inflammatory bowel disease (IBD) relies on old meta-analyses including exclusively non-Jewish White populations. Uncertainty persists regarding the role of smoking in other ethnicities. Methods We systematically searched Medline/PubMed, Embase and Scopus for studies examining tobacco smoking and the risk of developing IBD, i.e., Crohn’s disease (CD) or ulcerative colitis (UC). Two authors independently extracted study data and assessed each study’s risk-of-bias. We examined heterogeneity and small-study effect, and calculated summary estimates using random-effects models. Stratified analyses and meta-regression were employed to study the association between study-level characteristics and effect estimates. The strength of epidemiological evidence was assessed through prespecified criteria. Results We synthesized 57 studies examining the smoking-related risk of developing CD and UC. Non-Jewish White smokers were at increased risk of CD (29 studies; RR: 1.95, 95% CI: 1.69‒2.24; moderate evidence). No association was observed in Asian, Jewish and Latin-American populations (11 studies; RR: 0.97; 95% CI: 0.83–1.13), with no evidence of heterogeneity across these ethnicities. Smokers were at reduced risk of UC (51 studies; RR: 0.55, 95% CI: 0.48–0.64; weak evidence) irrespectively of ethnicity; however, cohort studies, large studies and those recently published showed attenuated associations. Conclusions This meta-analysis did not identify any increased risk of CD in smokers in ethnicities other than non-Jewish Whites, and confirmed the protective effect of smoking on UC occurrence. Future research should characterize the genetic background of CD patients across different ethnicities to improve our understanding on the role of smoking in CD pathogenesis.
