Gut dysmotility develops in individuals during and after recovering from infective acute gastroenteritis and it is apparently due to a direct effect of circulating lipopolysaccharides (LPS). This is an endotoxin with a prooxidant activity derived from gram-negative bacteria. Due to the lack of human models available so far, the mechanisms underlying LPS-induced gut dysmotility are, however, poorly investigated. In the present work long-term effects of LPS and their reversibility have been assessed by means of different analytical cytology methods on pure primary cultures of human colonic smooth muscle cells...

Inflammation of the gastrointestinal tract is a common reason for a variety of human diseases. Animal research models are critical in investigating the complex cellular and molecular of intestinal pathology. Although the tunica mucosa is often the organ of interest in many inflammatory diseases, recent works demonstrated that the muscularis externa (ME) is also a highly immunocompetent organ that harbours a dense network of resident immunocytes.(1,2) These works were performed within the standardized model of intestinal manipulation (IM) that leads to inflammation of the bowel wall, mainly limited to the ME...

BACKGROUND: The US Centers for Disease Control and Prevention estimates 20.9 million norovirus infections annually in the United States. Although the acute disease burden is sizeable, emerging data suggest norovirus may be associated with chronic gastrointestinal problems. We identified known outbreaks in US military recruits and used the Defense Medical Encounter Database (DMED) to identify the risk of new onset functional gastrointestinal disorders (FGD) and gastroesophageal reflux disease (GERD)...

Abdominal pain, bloating, early satiety, and changes in bowel habits are common presenting symptoms in individuals with functional GI disorders. Emerging data suggests that these symptoms may be associated with mast cell excess and/or mast cell instability in the GI tract. The aim of this retrospective study was to evaluate the contribution of mast cells to the aforementioned symptoms in individuals with a history of atopic disease. A retrospective chart review of individuals seen in a university GI practice was conducted and twenty-four subjects were identified...

OBJECTIVES: Esophageal subepithelial fibrosis has been reported in adults with eosinophilic esophagitis (EE). Our goal was to determine the prevalence of esophageal fibrosis in children with EE, to determine whether it is specific for EE, and to correlate it with clinical and pathological features. PATIENTS AND METHODS: Twenty-one children with EE, 7 with eosinophilic gastroenteritis, 6 with gastroesophageal reflux disease, and 17 control children were studied. Distal esophageal biopsy specimens containing lamina propria were evaluated for extent of subepithelial collagen deposition by use of trichrome staining...

PURPOSE OF REVIEW: Eosinophilic inflammation of the gastrointestinal tract is either increasing in frequency or being better recognized. Whichever is the case, clinical needs to meet this new challenge include establishing diagnostic criteria, identifying the natural history and determining effective, tolerable treatments. RECENT FINDINGS: During the last 5 years, the emergence of eosinophilic esophagitis stimulated many case series; the new frontiers relate to understanding disease pathogenesis and maintenance treatments...

Highly inducible heme oxygenase (HO)-1 is protective against acute and chronic inflammation. HO-1 generates carbon monoxide (CO), ferrous iron, and biliverdin. The aim of this study was to investigate the protective effects of biliverdin against sepsis-induced inflammation and intestinal dysmotility. Cecal ligation and puncture (CLP) was performed on Sprague-Dawley rats under isoflurane anesthesia with and without intraperitoneal biliverdin injections, which were done before, at the time of CLP, and after CLP...

Regulation of membrane ion channels by second messengers is an important mechanism by which gastrointestinal smooth muscle excitability is controlled. Receptor-mediated phosphorylation of Ca(2+) channels has been known for some time; however, recent findings indicate that these channels may also modulate intracellular signaling. The plasmalemma ion channels may also function as a point of convergence between different receptor types. In this review, the molecular mechanisms that link channel function and signal transduction are discussed...

OBJECTIVES: Cystic fibrosis patients have a wide spectrum of gastrointestinal disorders. The aim of this study was to investigate the function of gastroenteric neuromusculature and its response to a prokinetic. METHODS: 14 CF children aged 8.6 + 1.3 years were studied by electrogastrography and compared to 10 age-matched controls. A second recording was performed in CF patients after administration of cisapride (0.3 mg/kg). Parameters analyzed were percentage of normal gastric rhythm (2...

In spite of a claim by Kobayashi (1990) that they do not correspond to the cells originally depicted by CAJAL, a particular category of fibroblast-like cells have been identified in the gut by electron microscopy (Faussone-Pellegrini, 1977; Thuneberg, 1980) and by immunohistochemistry for Kit protein (Maeda et al., 1992) under the term of the "interstitial cells of Cajal (ICC)". Generating electrical slow waves, the ICC are intercalated between the intramural neurons and the effector smooth muscular cells, to form a gastroenteric pacemaker system...

Abdominal pain/discomfort, bloating, need to rush to the toilet, straining, feeling of incomplete bowel emptying and alternating periods of diarrhea and constipation is the clinical definition of the irritable bowel syndrome. The internationally used syndrome definition is based on expert opinions and answers to patient questionnaires. When symptoms are registered prospectively, abdominal pain starts or worsens after meals and is not relieved by defecation. As in the general population patients with the syndrome define diarrhea as loose stools and constipation as hard stools regardless of stool frequencies...

BACKGROUND: Recent studies suggest that esophageal dysmotility occurring in systemic sclerosis might be caused by neurotransmitter levels decrease. The aim of the present study is to value VIP plasma levels, and to relate them with the pressure of the inferior esophageal sphincter (IES) and the capillaroscopy score in a group of patients affected by Systemic Sclerosis (SSc). METHODS: Eleven subjects affected by SSc (eight male and three female, age from 30 to 72 years old) have been studied through esophageal manometry, capillaroscopy and VIP plasma levels evaluation...

BACKGROUND/AIMS: The pathogenesis of dyspeptic/reflux symptoms and the clinico-pathologic profile of affected patients are still poorly understood. To improve our knowledge in this field we carried out a systematic, comparative analysis of symptom profiles and histopathologic patterns of oesophagogastroduodenal mucosa in a series of 221 subjects, 140 with and 81 without endoscopic evidence of hiatal hernia. Of these, 190 showed reflux and/or dyspeptic symptoms. METHODS: Before endoscopy, all the subjects were questioned about the presence and severity of 12 individual symptoms...
