Prospective Study Evaluating the Prevalence of Intestinal Dysfunction

The intestinal tract has multiple functions within the body beyond its primary function of nutrient absorption. It acts as a true barrier protecting the body from living microorganisms and antigens in the intestinal lumen. Impairment of any component of the intestinal barrier results in nutrient malabsorption, an altered local digestive immune response, and increased intestinal permeability. The primary function of this barrier is to limit the access of the contents of the intestinal lumen, which particularly includes the bacterial components of the microbiota, to the internal environment and the circulation. This physical barrier function is provided by a monolayer of epithelial cells, closely connected to each other by intercellular junctions (tight junctions, adherens and desmosomes, as well as by the mucus which covers the apical surface of the cells, the constituents of which, mucins, are secreted by the goblet cells. The term intestinal barrier is also used in a broader sense including a protective role against the invasion of environmental pathogens, while allowing toleranSepsis-associated intestinal failure is often underestimated, yet it is found in 20 to 60% of ICU (Intensive Care Unit)vpatients. However, its prognosis is poorly documented. For example, there is no consensus definition of this dysfunction or validated biomarkers for rapid assessment. Consequently, it does not appear in most prognostic scores (SOFA, IGS2, etc.). Intestinal permeability, a risk factor for bacterial translocation when elevated, is increased in ICU (Intensive Care Unit) patients and associated with multiorgan failure system (MODS), particularly in cases of intestinal fasting. However, there is currently no validated marker of acute intestinal failure in intensive care or intensive care.ce towards commensal flora and foods.
