Considering Intestinal Hyperpermeability and Immune-Inflammatory Metabolism in the Treatment of Food Allergy

Abstract

Food Allergy is a chronic systemic immuno-inflammatory condition that depends on several factors, but, above all, the gastrointestinal epithelial barrier. The rupture of this intestinal barrier results in a deleterious increase in intestinal permeability allowing the paracellular permeation of molecules greater than 150 Da into the bloodstream, producing an equivalent immune response, decreasing the immune tolerance. Intestinal Hyperpermeability has been linked not only to food allergy but also to Metabolic Syndrome and Non-Alcoholic Fat Liver Disease. Here we review the factors that contribute to producing Intestinal Hyperpermeability, as well the factors that contribute to the restoration of the epithelial barrier, improving the clinical outcome of food-allergic patients. The main factors that increase the Intestinal Hyperpermeability are A) Immune-Inflammatory (food allergy itself and autoimmune conditions); B) Iatrogenic (steroids, non-steroidal anti-inflammatories, antacids, antibiotics, and gastric-bypass surgeries); C) Infectious (rotavirus, HIV, SARS-CO2, Helicobacter pylori, Candida albicans, etc.); and D) Lifestyle-related (alcoholic beverages, food addiction, food overconsumption, consumption of industrialized food with high-fructose content and emulsifiers). The main factors that restore the intestinal barrier and immune tolerances are the intestinal microbiota and functional nutrients such as Vitamin A and vegetal fibers. Mucoprotectants agents, such as gelatin tannate and xyloglucan, are in study to become part of the medical arsenal to treat Intestinal Hyperpermeability conditions.

“…The disruption of the intestinal mucous layer impacts the gut microbiota and enhances the penetration of bacterial toxins, which is associated with colitis, metabolic syndrome, and food allergy [57], [58]. Intestinal hyperpermeability may be a cause and a consequence of immune-inflammatory conditions, such as those observed in food-allergic syndromes [59]. Patients diagnosed with IBD had a significant increase in disease activity when receiving a supplement of S. cerevisiae over a low-yeast diet [60].…”
