As mast cells have been highlighted in the pathogenesis of diarrhea-predominant irritable bowel syndrome, a new term "mastocytic enterocolitis" was suggested by Jakate and colleagues to describe an increase in mucosal mast cells in patients with chronic intractable diarrhea and favorable response to treatment with antihistamines. Although it is not an established disease entity, two cases have been reported in the English medical literature. Here, for the first time in Asia, we report another case of chronic intractable diarrhea caused by gastrointestinal mastocytosis...

CONTEXT: Mastocytic enterocolitis is a recently described entity defined by chronic diarrhea of unknown etiology and normal colon biopsy results with increased mast cells (MCs) seen on special stains. These patients may benefit from mast cell stabilizers; however, the clinical utility of MC counts remains unknown. OBJECTIVE: To determine the clinical utility of colonic MC counts on normal biopsies in patients with chronic diarrhea of unknown etiology. DESIGN: Blinded MC counts using a c-Kit stain were performed in 76 consecutive patients with chronic diarrhea of unknown etiology who had normal colon biopsy results and in 89 consecutive control patients presenting for screening colonoscopy...

Counting mast cells in gastrointestinal (GI) mucosal biopsies is becoming an increasingly common practice. The primary reason for this exercise is to evaluate for possible involvement by systemic mastocytosis (SM). However, the features of mastocytosis in GI biopsies are not well described. In addition, recent studies have suggested that increased mast cells may be involved in the pathogenesis of some cases of diarrhea-predominant irritable bowel syndrome (IBS); the term "mastocytic enterocolitis" has been proposed for such cases...

Microscopic colitis is characterized by chronic or intermittent watery diarrhoea. Microscopic colitis is a common cause of chronic diarrhoea in predominantly older adults. The underlying mechanism in the pathogenesis of microscopic colitis remains unspecified. Microscopic colitis including colitis collagenous, lymphocytic, microscopic colitis with incomplete findings, minimal change colitis, eosinophilic colitis, Brainerd´s diarrhoea, graft-versus-host disease, mastocytic enterocolitis and postinfectious irritable bowel syndrome...

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...

The prevalence of chronic diarrhea within the U.S. population has been reported to be as high as five per cent, and numerous causes have been identified. Especially in patients suffering from rheumatoid arthritis drug therapy should be considered as possible cause. We report a case of chronic diarrhea triggered by mastocytic enterocolitis in a patient suffering from rheumatoid arthritis. Systemic mastocytosis and other causes of chronic diarrhea, especially therapy with methotrexate, were carefully ruled out...

The function of mast cells in allergic inflammatory reactions is well documented in the literature. Mast cells also play an important role in the regulation of gastrointestinal visceral sensitivity and vascular permeability. Several studies have noted an increased number of mast cells in the mucosa of patients with gastrointestinal diseases such as irritable bowel syndrome, mastocytic enterocolitis, and systemic mastocytosis. The role of mast cells in the symptomatology of these and other diseases has only recently been fully appreciated and could provide avenues for new therapeutic opportunities...

CONTEXT: In some adult patients with chronic intractable diarrhea, the diagnosis remains elusive even after detailed evaluations, and colonic or duodenal biopsy specimens may appear unremarkable on routine hematoxylin-eosin staining. OBJECTIVES: To assess the concentration of mast cells in colonic or duodenal biopsy specimens by immunohistochemical analysis for mast cell tryptase from patients with chronic intractable diarrhea and to evaluate their response to drugs affecting mast cell function...

Eosinophilic gastroenterocolitis with peripheral eosinophilia was induced in rats fed a diet containing 2.5% or 5.0% iron lactate for 3 mo. Additional findings consistent with iron overload were also observed. Microscopically, the lesions consisted of eosinophilic infiltrations in the mucosa and submucosa along the whole length of the gastrointestinal tracts, increased surface area of the gastric mucosal propria covered with mucous cells, and increased apoptotic bodies in the gastric glandular neck of rats in the 2...

A method has been for counting the mastocytes on 0.1 mm2 of intestinal mucosa in patients with chronic enterocolitis, gluten enteropathy, ulcerous colitis in a stage of exacerbation and in controls. The comparison of the results obtained in the separate groups of patients reveal an increased number of mastocytes in gluten enteropathy--mean = 21.01 +/- 6 as compared with the chronic enterocolitis, where mean = 9.79 +/- 3.83 (p = 0.002). Higher values of mastocytes in rectal mucosa were observed in the patients with ulcerous mucosa--mean = 15...
