introduction and aims: microscopic colitis has been generally recognized as lymphocytic colitis and collagenous colitis: two inflammatory diseases of large intestine without a definite origin. the colon appears normal by colonoscopy. so, biopsy of the colonic mucosa is mandatory for diagnosis. materials and methods: as a descriptive design we assessed epidemiological, clinical and laboratory fi...

Microscopic colitis is a common cause of chronic, nonbloody diarrhea. Microscopic colitis is more common in women than men and usually affects patients in their sixth and seventh decade. This article reviews the etiology and medical management of microscopic colitis. The etiology of microscopic colitis is unknown, but it is associated with autoimmune disorders, such as celiac disease, polyarthr...

Microscopic colitis is currently classified as a chronic inflammatory bowel disorder and encompasses two entities: lymphocytic colitis and collagenous colitis. Patients with microscopic colitis present with a well-tolerated chronic watery diarrhea, sometimes with abdominal pain. Colonoscopy is normal. Diagnosis of microscopic colitis is established by histologic examination of colonic biopsies,...

Microscopic colitis is a common cause of chronic diarrhea. Over the last years the incidence and the prevalence of microscopic colitis are rising and this rise is largely attributed to a rising awareness, and concomitantly an increasing number of diagnoses are made. Patients with microscopic colitis report watery, nonbloody diarrhea of chronic, intermittent, or chronic recurrent course. Followi...

We read the interesting paper by Pardi et al on the epidemiology of microscopic colitis in Olmsted County, Minnesota, USA (Gut 2007; 56: 504–8). They concluded that the incidence of microscopic colitis increased significantly over time, and by the end of the study, the incidence and prevalence were significantly higher than reported previously. In fact, compared with other epidemiological studi...

BACKGROUND Microscopic colitis presents with similar symptoms to classic inflammatory bowel diseases. Osteoporosis is a common complication of Crohn's disease but there are no data concerning bone metabolism in microscopic colitis. AIMS The aim of the present study was to evaluate bone density and metabolism in patients with microscopic colitis. METHODS Fourteen patients microscopic colitis...

BACKGROUND/AIMS Microscopic colitis is characterized by chronic watery diarrhea with specific pathological changes that can be diagnosed by microscopic examination. We performed immunohistochemical analysis of proinflammatory cytokines to investigate the pathogenic mechanism of microscopic colitis. METHODS This study consisted of six patients with lymphocytic colitis, six patients with collag...
