SUDD and AD do not show colonic bacterial overgrowth, but a significant difference in the levels of fecal A. muciniphila was observed. Moreover, increasing expression of some metabolites as expression of different AD and SUDD metabolic activity was found.
Clinical, laboratory, and radiological findings may easily differentiate uncomplicated from complicated diverticulitis of the colon. This integrated approach may be helpful in clinical settings.
SUMMARY BackgroundUlcerative colitis with diverticulosis (UCD), segmental colitis associated with diverticulosis (SCAD) and acute uncomplicated diverticulitis (AUD) may affect the same colonic regions, but the real incidence of these entities in clinical practice is unknown.
The term “microbiota” means genetic inheritance associated with microbiota, which is about 100 times larger than the guest. The tolerance of the resident bacterial flora is an important key element of immune cell function. A key role in the interaction between the host and the microbiota is played by Paneth cell, which is able to synthesize and secrete proteins and antimicrobial peptides, such as α/β defensins, cathelicidin, 14 β-glycosidases, C-type lectins, and ribonuclease, in response to various stimuli. Recent studies found probiotics able to preserve intestinal homeostasis by downmodulating the immune response and inducing the development of T regulatory cells. Specific probiotic strain, as well as probiotic-driven metabolic products called “postbiotics,” has been recently recognized and it is able to influence innate immunity. New therapeutic approaches based on probiotics are now available, and further treatments based on postbiotics will come in the future.
At this time small bowel biopsy seems to be the only correct procedure to diagnose a case of suspected celiac disease, especially in patients with mild symptoms or suspected for celiac disease, because they belong to high-risk groups.
This study shows clearly for the first time that OCTT is not only delayed in patients with active CD, but also that it is prolonged in ileal and ileocolonic rather than colonic localization of CD. Moreover we obtained these results using a simple, sensitive, non-invasive and repeatable method, namely, a lactulose hydrogen breath test.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
