Alternative Therapy in the Prevention of Experimental and Clinical Inflammatory Bowel Disease. Impact of Regular Physical Activity, Intestinal Alkaline Phosphatase and Herbal Products

Abstract

Inflammatory bowel diseases (IBD), such as ulcerative colitis and Crohn's disease, are multifactorial, chronic, disabling, and progressive diseases characterised by cyclical nature, alternating between active and quiescent states. While the aetiology of IBD is not fully understood, this complex of diseases involve a combination of factors including the genetic predisposition and changes in microbiome as well as environmental risk factors such as high-fat and low-fibre diets, reduced physical activity, air pollution and exposure to various toxins and drugs such as antibiotics. The prevalence of both IBD and obesity is increasing in parallel, undoubtedly proving the existing interactions between these risk factors common to both disorders to unravel poorly recognized cell signaling and molecular alterations leading to human IBD. Therefore, there is still a significant and unmet need for supportive and adjunctive therapy for IBD patients directed against the negative consequences of visceral obesity and bacterial dysbiosis. Among the alternative therapies, a moderate-intensity exercise can benefit the health and well-being of IBD patients and improve both the healing of human IBD and experimental animal colitis. Intestinal alkaline phosphatase (IAP) plays an essential role in the maintenance of intestinal homeostasis intestinal and the mechanism of mucosal defence. The administration of exogenous IAP could be recommended as a therapeutic strategy for the cure of diseases resulting from the intestinal barrier dysfunction such as IBD. Curcumin, a natural anti-inflammatory agent, which is capable of stimulating the synthesis of endogenous IAP, represents another alternative approach in the treatment of IBD. This review was designed to discuss potential "nonpharmacological" alternative and supplementary therapeutic approaches taking into account epidemiological and pathophysiological links between obesity and IBD, including changes in the functional parameters of the intestinal mucosa and alterations in the intestinal microbiome.
