Attenuated polyposis could be defined as a variant of familial adenomatous polyposis (FAP) in which synchronous polyps of the large bowel range between 10 and 99. We analysed all cases of attenuated polyposis observed over the last 30 years with the objectives: (A) to classify the disease according to different type and proportion of polyps; (B) To ascertain the contribution of APC and MutYH genes; (C) to discover features which could arise the suspicion of mutations; (D) To obtain indications for management and follow-up...

OBJECTIVES: Both the innate and the adaptive immune responses contribute to the onset of chronic inflammation in spondyloarthritis (SpA). The association between SpA and inflammatory bowel disease (IBD, enteropathic SpA-ESpA) has been largely established and suggests a shared pathophysiology. There is evidence that innate lymphoid cells (ILC) are involved in the pathogenesis of both SpA and IBD while no evidence has been reported to date on ESpA. We aimed to analyse for the first time the frequency and cytokine expression of ILC in peripheral blood from ESpA patients compared with both IBD and healthy subjects...

Serrated polyposis syndrome (SPS) is closely associated with the initiation and development of colorectal cancer (CRC), however, there is few research on SPS in China. Serrated polyps can be divided into hyperplastic polyps, sessile serrated polyps and traditional serrated polyps. The diagnosis standard of SPS is as following: (1) There are at least 5 serrated lesions in proximal colon, and diameter of more than 2 lesions is >10 mm; (2) The patient has one serrated polyp with family history of SPS; (3) More than 20 serrated polyps can be found in the entire large bowel...

The enteric nervous system (ENS) is recognized as a second brain because of its complexity and its largely autonomic control of bowel function. Recent progress in studying the interactions between the ENS and the central nervous system (CNS) has implicated alterations of the gut/brain axis as a possible mechanism in the pathophysiology of autism spectrum disorders (ASDs), Parkinson's disease (PD) and other human CNS disorders, whereas the underlying mechanisms are largely unknown because of the lack of good model systems...

For many years, there has been confusion about the role that nutrition plays in inflammatory bowel diseases (IBD). It is apparent that good dietary advice for one individual may prove inappropriate for another. As with many diseases, genome-wide association studies across large collaborative groups have been important in revealing the role of genetics in IBD, with more than 200 genes associated with susceptibility to the disease. These associations provide clues to explain the differences in nutrient requirements among individuals...

INTRODUCTION: The aim of the present study was to evaluate clinical presentation and management of sigmoid volvulus in children. Sigmoid volvulus is one of the three leading causes of acute obstruction of the colon and is between 50 and 90% of all large bowel volvulus. In the pediatric population only 3 to 5% of bowel obstructions are caused by volvulus and there are less than 100 cases reported in the literature. The presence of a redundant sigmoid with a narrow mesentery (dolicosigmoide) is a prerequisite for the volvulus formation...

Microscopic colitis (MC) is frequent, although still uncommonly diagnosed, cause of chronic diarrhea. The etiopathology of MC is unknown but this disease has strong influence on patient's quality of life (measured by health-related quality of life - HRQoL). MC is characterized by microscopic abnormalities in large bowel's mucosa whereas endoscopic and radiological examination findings are normal. The treatment of MC is an essential social and financial problem due to its frequency in society. Thanks to the results of some controlled research which judged efficiency of some medicines as well as advisory groups recommendations, the MC therapy is nowadays going from empiric to accordance with evidence based medicine...

BACKGROUND: Anti-tumor necrosis factor (anti-TNF) monoclonal antibodies have revolutionized the treatment of inflammatory bowel diseases (IBD). However, because of their complexity, their production is expensive contributing to their high price. As the patent protection of these therapies has expired in several countries, biosimilars have been developed to reduce the healthcare costs. The aim of this article is to review the literature on the safety, efficacy and immunogenicity of biosimilars in IBD...

BACKGROUND: Berberine (BBR) is a traditional antimicrobial herbal medicine. Recently, BBR has gained popularity as a supplement to lower blood lipids, cholesterol and glucose. Bile acids (BAs) are known to regulate blood levels of triglycerides, cholesterol, glucose and energy homeostasis, and gut flora play an important role in BA metabolism. However, whether BBR alters BAs metabolism or dose-response effect of BBR on gut flora is unknown. METHODS: In this study, the effects of various doses of BBR on the concentrations of BAs in liver and serum of male C57BL/6 mice were determined by UPLC-MS/MS, and the expression of BA-related genes, as well as the amount of 32 of the most abundant gut bacterial species in the terminal ileum and large intestine of male C57BL/6 mice were quantified by RT-PCR and Quantigene 2...

Cancer development is often associated with chronic inflammation. To date, research into inflammation-induced cancer has largely focused on chemokines, cytokines, and their downstream targets. These inflammatory mediators may promote tumor growth, invasion, metastasis, and facilitate angiogenesis. However, the exact mechanisms by which inflammation promotes neoplasia remain unclear. Inflammatory bowel disease (IBD) is characterized by recurrent, idiopathic intestinal inflammation, the complications of which are potentially fatal...
