Apart from inflammatory bowel diseases (IBD), there are several other form of colitis that may resemble macroscopically IBD, entering the differential diagnosis. These forms are represented by infectious colitis, ischemic colitis, pseudomembranous colitis, colitis related to diverticular disease, colitis related to mucosal prolapse, drug colitis, allergic colitis, and microscopic colitis. Howev...

There is a recognised association between the "microscopic" forms of colitis and coeliac disease. There are a variety of subtle small intestinal changes in patients with "latent" gluten sensitivity, namely high intraepithelial lymphocyte (IEL) counts, abnormal mucosal permeability, and high levels of secretory IgA and IgM antibody to gliadin. These changes have hitherto not been investigated in...

What are Collagenous and Lymphocytic Colitis? Collagenous and lymphocytic colitis are clinical and pathologic syndromes representing forms of microscopic colitis that affect the large intestine. Both disorders usually present in middle-aged patients in the fifth or sixth decade of life. Collagenous colitis primarily affects women. The predominance in the female to male population is 8:2. Lympho...

Background and objectives: Inflammatory bowel diseases (IBD) are among the most prevalent diseases in developed countries. In general, IL-6 and TNF-α are considered as the main causes of tissue damage in the intestine. Salvadora persica is a domestic and abundant plant growing in some central and southern areas of Iran. The main objective of the current study was to ev...

A patient is reported with chronic abdominal pain, diarrhoea, and associated radiological and endoscopic abnormalities of the sigmoid colon. Light and electron microscopic study of colorectal mucosa showed abnormal collagenous thickening of the subepithelial basement membrane. The authors felt that the clinical and morphological features justified a diagnosis of collagenous colitis. Review of t...

INTRODUCTION In this study we investigated the effect of gall of Quercus brantii Lindl., a traditional Iranian medicine, in a murine model of experimental colitis induced in male rats by rectal administration of 2,4,6-trinitrobenzene sulfonic acid (TNBS). MATERIAL AND METHODS Quantification of the main active components was done for estimation of total phenolic content and free gallic acid. G...

Microscopic colitis, comprising collagenous and lymphocytic colitis, is characterized clinically by chronic watery diarrhea, and a macroscopically normal colonic mucosa where diagnostic histopathological features are seen on microscopic examination. The annual incidence of each disorder is 4-6/100 000 inhabitants, with a peak incidence in 60-70-year-old individuals and a noticeable female predo...

Objective: Colitis is an inflammatory bowel disease with unknown etiology where many factors might play a role.  Adiantum capillus-veneris mayhave beneficial effects in colitis because of its anti-inflammatory, antioxidant, wound healing and antimicrobial effects. The aim of this study was to explore the anti-inflammatory and anti-ulcerative effects of A. capillus-...

Although macrophages are considered a critical factor in determining the severity of acute inflammatory responses in the gut, recent evidence has indicated that macrophages may also play a counterinflammatory role. In this study, we examined the role of a macrophage subset in two models of colitis. Macrophage colony-stimulating factor (M-CSF)-deficient osteopetrotic mice (op/op) and M-CSF-expre...
