Gerodontology 2005 Jun;22(2):91-7. Relationship of number of remaining teeth to health-related quality of life in community-dwelling elderly. Akifusa S, Soh I, Ansai T, Hamasaki T, Takata Y, Yohida A, Fukuhara M, Sonoki K,Takehara T. Department of Preventive Dentistry, Kyushu Dental College, Fukuoka, Japan. Gerodontology Jun;22(2):91-7. OBJECTIVE: The aim of this study was to evaluate the relationship between number of remaining teeth and health-related quality of life in community-dwelling elderly. SUBJECTS: A total of 207 participants who were community-dwelling, 85 years of age. Data were from a population-based study of age-related general and oral health in Fukuoka Prefecture, Japan. MEASUREMENTS: The Japanese version of the Short Form 36 Health Survey (SF-36). RESULTS: The mental component score for the participants, from the SF-36, was higher than the Japanese national norm for those aged > or = 70 years. There were no significant differences in the mean of any scores on the SF-36 by having spouse, living with family, or education level. The mean of the SF-36 scores of physical functioning (PF) and of the physical component scores were significantly higher in the 85-year-old participants with > or = 20 teeth than in those with < or = 19 teeth (p < 0.05 and p < 0.01 respectively). In addition, a significant difference (p < 0.05) was observed between the mean of participants with > or = 20 teeth and those with < or = 19 teeth after adjustment for region where the participant lived, activities of daily living (ADL), and sex. The PF (p < 0.001), role-physical (p < 0.005), bodily pain (p < 0.001), vitality (p < 0.001), social functioning (p < 0.05), and physical component (p < 0.001) scores were significantly higher in participants with a good activities of daily living (ADL) assessment. However, ADL was not associated with the number of teeth. CONCLUSIONS: The findings of the present study indicated that 85-year-old participants with > or = 20 teeth had better subjective physical health than those with < or = 19 teeth. CONCLUSIONS: Cette étude indique que les participants âgés de 85 ans avec 20 dents ou + ont une meilleure santé physique subjective que ceux avec 19 dents ou +.

27 Proton pump inhibitors exacerbate NSAID-induced small intestinal injury
by inducing dysbiosis. Wallace JL, Syer S, Denou E, de Palma G, Vong L, McKnight W, Jury J, Bolla M, Bercik P, Collins SM, Verdu E, Ongini E. Gastroenterology Oct;141(4): , 1322.e1-5. BACKGROUND & AIMS: Proton pump inhibitors (PPIs) and nonsteroidal anti-inflammatory drugs (NSAIDs) are among the most commonly used classes of drugs, with the former frequently coprescribed to reduce gastroduodenal injury caused by the latter. However, suppression of gastric acid secretion by PPIs is unlikely to provide any protection against the damage caused by NSAIDs in the more distal small intestine. METHODS: Rats were treated with antisecretory doses of omeprazole or lanzoprazole for 9 days, with concomitant treatment with anti-inflammatory doses of naproxen or celecoxib on the final 4 days. Small intestinal damage was blindly scored, and changes in hematocrit were measured. Changes in small intestinal microflora were evaluated by denaturing gradient gel electrophoresis and reverse-transcription polymerase chain reaction. RESULTS: Both PPIs significantly exacerbated naproxen- and celecoxib-induced intestinal ulceration and bleeding in the rat. Omeprazole treatment did not result in mucosal injury or inflammation; however, there were marked shifts in numbers and types of enteric bacteria, including a significant reduction (∼80%) of jejunal Actinobacteria and Bifidobacteria spp. Restoration of small intestinal Actinobacteria numbers through administration of selected (Bifidobacteria enriched) commensal bacteria during treatment with omeprazole and naproxen prevented intestinal ulceration/bleeding. Colonization of germ-free mice with jejunal bacteria from PPI-treated rats increased the severity of NSAID-induced intestinal injury, as compared with mice colonized with bacteria from vehicle-treated rats. CONCLUSIONS: PPIs exacerbate NSAID-induced intestinal damage at least in part because of significant shifts in enteric microbial populations. Prevention or reversal of this dysbiosis may be a viable option for reducing the incidence and severity of NSAID enteropathy.

30 Butyrate: implications for intestinal function.
Leonel AJ, Alvarez-Leite JI. Curr Opin Clin Nutr Metab Care Jul 12. PURPOSE OF REVIEW: Butyrate is physiologically produced by the microbial fermentation of dietary fibers and plays a plurifunctional role in intestinal cells. This review examines the recent findings regarding the role and mechanisms by which butyrate regulates intestinal metabolism and discusses how these findings could improve the treatment of several gastrointestinal disorders. RECENT FINDINGS: Butyrate is more than a primary nutrient that provides energy to colonocytes and acts as a cellular mediator in those cells through several mechanisms. One remarkable property of butyrate is its ability to inhibit histone deacetylases, which is associated with the direct effects of butyrate and results in gene regulation, immune modulation, cancer suppression, cell differentiation, intestinal barrier regulation, oxidative stress reduction, diarrhea control, visceral sensitivity and intestinal motility modulation. All of these actions make butyrate an important factor for the maintenance of gut health. SUMMARY: From studies published over 30 years, there is no doubt of the important role that butyrate plays in maintaining intestinal homeostasis. However, despite these effects, clinical studies are still required to validate the routine use of butyrate in clinical practice and, specifically, in the treatment of intestinal diseases.!!!

31 Mechanisms of disease: the role of intestinal barrier function in the pathogenesis of gastrointestinal autoimmune diseases. Fasano A, Shea-Donohue T. Nat Clin Pract Gastroenterol Hepatol Sep;2(9): The primary functions of the gastrointestinal tract have traditionally been perceived to be limited to the digestion and absorption of nutrients and electrolytes, and to water homeostasis. A more attentive analysis of the anatomic and functional arrangement of the gastrointestinal tract, however, suggests that another extremely important function of this organ is its ability to regulate the trafficking of macromolecules between the environment and the host through a barrier mechanism. Together with the gut-associated lymphoid tissue and the neuroendocrine network, the intestinal epithelial barrier, with its intercellular tight junctions, controls the equilibrium between tolerance and immunity to nonself-antigens. When the finely tuned trafficking of macromolecules is dysregulated in genetically susceptible individuals, both intestinal and extraintestinal autoimmune disorders can occur. This new paradigm subverts traditional theories underlying the development of autoimmunity, which are based on molecular mimicry and/or the bystander effect, and suggests that the autoimmune process can be arrested if the interplay between genes and environmental triggers is prevented by re-establishing intestinal barrier function. Understanding the role of the intestinal barrier in the pathogenesis of gastrointestinal disease is an area of translational research that encompasses many fields and is currently receiving a great deal of attention. This review is timely given the increased interest in the role of a 'leaky gut' in the pathogenesis of gastrointestinal diseases and the advent of novel treatmen strategies, such as the use of probiotics. Together with the gut-associated lymphoid tissue and the neuroendocrine network, the intestinal epithelial barrier, with its intercellular tight junctions, controls the equilibrium between tolerance and immunity to nonself-antigens.

32 Leaky gut and autoimmune diseases.
Fasano A. Clin Rev Allergy Immunol Feb ;42(1):71-8. Autoimmune diseases are characterized by tissue damage and loss of function due to an immune response that is directed against specific organs. This review is focused on the role of impaired intestinal barrier function on autoimmune pathogenesis. Together with the gut-associated lymphoid tissue and the neuroendocrine network, the intestinal epithelial barrier, with its intercellular tight junctions, controls the equilibrium between tolerance and immunity to non-self antigens. Zonulin is the only physiologic modulator of intercellular tight junctions described so far that is involved in trafficking of macromolecules and, therefore, in tolerance/immune response balance. When the zonulin pathway is deregulated in genetically susceptible individuals, autoimmune disorders can occur. This new paradigm subverts traditional theories underlying the development of these diseases and suggests that these processes can be arrested if the interplay between genes and environmental triggers is prevented by re-establishing the zonulin-dependent intestinal barrier function. Both animal models and recent clinical evidence support this new paradigm and provide the rationale for innovative approaches to prevent and treat autoimmune diseases.

41 Leaky gut and diabetes mellitus: what is the link?
de Kort S, Keszthelyi D, Masclee AA. Obes Rev Jun ;12(6): doi: /j X Diabetes mellitus is a chronic disease requiring lifelong medical attention. With hundreds of millions suffering worldwide, and a rapidly rising incidence, diabetes mellitus poses a great burden on healthcare systems. Recent studies investigating the underlying mechanisms involved in disease development in diabetes point to the role of the dys-regulation of the intestinal barrier. Via alterations in the intestinal permeability, intestinal barrier function becomes compromised whereby access of infectious agents and dietary antigens to mucosal immune elements is facilitated, which may eventually lead to immune reactions with damage to pancreatic beta cells and can lead to increased cytokine production with consequent insulin resistance. Understanding the factors regulating the intestinal barrier function will provide important insight into the interactions between luminal antigens and immune response elements. This review analyses recent advances in the mechanistic understanding of the role of the intestinal epithelial barrier function in the development of type 1 and type 2 diabetes. Given our current knowledge, we may assume that reinforcing the intestinal barrier can offer and open new therapeutic horizons in the treatment of type 1 and type 2 diabetes. Étant donné notre connaissance actuelle, nous pouvons supposer que le renforcement de la barrière intestinale peut offrir et ouvrir des nouveaux horizons thérapeutiques dans le traitement de type 1 et le diabète de type 2.
