Undiagnosed microscopic colitis: a hidden cause of chronic diarrhoea and a frequently missed treatment opportunity.

Frontline Gastroenterol 2020 5;11(3):228-234. Epub 2019 Jul 5.

The Institute of Health and Society, Faculty of Medical Sciences, Newcastle University, Newcastle upon Tyne, UK.

Microscopic colitis (MC) is a treatable cause of chronic, non-bloody, watery diarrhoea, but physicians (particularly in primary care) are less familiar with MC than with other causes of chronic diarrhoea. The colon in patients with MC is usually macroscopically normal. MC can only be diagnosed by histological examination of colonic biopsies (subepithelial collagen band >10 µm (collagenous colitis) or >20 intraepithelial lymphocytes per 100 epithelial cells (lymphocytic colitis), both with lamina propria inflammation).

Biopsies From Ascending and Descending Colon Are Sufficient for Diagnosis of Microscopic Colitis.

Clin Gastroenterol Hepatol 2020 Feb 25. Epub 2020 Feb 25.

Department of Pathology and Laboratory Medicine. Electronic address:

Background & Aims: Lymphocytic and collagenous colitis are types of microscopic colitis (MC) that commonly cause chronic watery diarrhea, but there are no macroscopic features of MC that can be detected during colonoscopy. Endoscopists therefore often collect multiple random colonic biopsies, potentially oversampling, increasing times of colonoscopy and slide review. We sought to identify sites from which biopsies could be taken and analyzed to identify patients with MC with a high level of sensitivity and determine the appropriate number of biopsies to take at these sites.

Unit of Gastroenterology, Molinette-SGAS Hospital, Turin, Italy -

Microscopic colitis (MC) is diagnosed in presence of microscopic alterations of colonic mucosa, in patients without macroscopic lesions who referred for chronic diarrhea. The two types of MC are lymphocytic colitis (LC) and collagenous colitis (CC), but it is unclear whether these are the different expression of one unique disease or if they are distinct conditions. Today, although MC represents a consistent health problem, being responsible for a large part of gastroenterological consultations for diarrhea, it remains often underestimated. Read More

J Crohns Colitis 2019 Mar;13(3):337-340

Department of Gastroenterology and Hepatology, University Hospitals Leuven, KU Leuven, Herestraat, Leuven, Belgium.

Background: Evidence for second-line therapy in patients with microscopic colitis [MC] failing budesonide is scarce, although anti-tumour necrosis factors [anti-TNFs], methotrexate and azathioprine have been reported to be effective in small cohort studies. Vedolizumab, a monoclonal antibody targeting α4β7-integrin, prevents homing of T-cells to the gut. We evaluated clinical remission with vedolizumab in budesonide-refractory MC patients. Read More

High prevalence of irritable bowel syndrome-type symptoms in microscopic colitis: implications for treatment.

Therap Adv Gastroenterol 2018 21;11:1756284818783600. Epub 2018 Jun 21.

Leeds Gastroenterology Institute, St James's University Hospital, Leeds, UK Leeds Institute of Biomedical and Clinical Sciences, University of Leeds, Leeds, UK.

Background: Patients with microscopic colitis (MC) often present with abdominal pain and diarrhoea, and previous data suggest that there may be overlap between MC and irritable bowel syndrome (IBS). We evaluated the prevalence of IBS-type symptoms in patients with MC, and assess the impact of these symptoms on psychological health and quality of life.

Methods: We conducted a cross-sectional survey of individuals with a histological diagnosis of MC, collecting demographic data, Rome III IBS-type symptoms, and mood, somatization, and quality of life data. Read More

GI Research Group, School of Medicine, Medical Sciences and Nutrition, University of Aberdeen, Aberdeen,, AB25 2ZD, UK.

In recent years, an increasing number of Campylobacter species have been associated with human gastrointestinal (GI) diseases including gastroenteritis, inflammatory bowel disease, and colorectal cancer. Campylobacter concisus, an oral commensal historically linked to gingivitis and periodontitis, has been increasingly detected in the lower GI tract. In the present study, we generated robust genome sequence data from C. Read More

The subtypes of microscopic colitis from a pathologist's perspective: past, present and future.

Ann Transl Med 2018 Feb;6(3):69

Digital Pathology, Visiopharm, Hørsholm, Denmark.

Microscopic colitis (MC) is a chronic inflammatory bowel disease, encompassing a triad of chronic diarrhea, normal endoscopy and characteristic histological findings. MC embraces two histological subtypes described as lymphocytic colitis (LC) and collagenous colitis (CC). The diagnostic criteria of MC were established several years ago and the histological description of LC and CC was based almost exclusively on heamatoxylin-eosin (HE) stained sections. Read More

Decreased risk for microscopic colitis and inflammatory bowel disease among patients with reflux disease.

Colorectal Dis 2018 09 24;20(9):813-820. Epub 2018 Apr 24.

Miraca Life Sciences, Irving, TX, USA.

Aim: Previous studies have found an increased risk for microscopic colitis (MC) associated with proton pump inhibitors. In patients with ulcerative colitis (UC) or Crohn's disease (CD), proton pump inhibitors have been associated with an increased risk for IBD flares and impaired outcomes. The aim of this study was to test the epidemiological associations between gastro-oesophageal reflux disease (GERD) and MC, UC or CD in a large database. Read More

Oral budesonide in gastrointestinal and liver disease: A practical guide for the clinician.

J Gastroenterol Hepatol 2018 Mar 30. Epub 2018 Mar 30.

Department of Gastroenterology, Institute of Translational Medicine, Liverpool, UK.

Oral budesonide is a second-generation steroid that allows local, selective treatment of the gastrointestinal tract and the liver, minimizing systemic exposure. The results of randomized trials comparing budesonide versus placebo or active comparators have led to expert recommendations that budesonide be used to treat mild or moderate active ileocecal Crohn's disease, microscopic colitis (including both collagenous and lymphocytic colitis), ulcerative colitis, and non-cirrhotic autoimmune hepatitis. The mechanism of budesonide action obviates the need for dose tapering due to safety reasons after induction therapy. Read More

Microscopic ileitis in diverted and nondiverted enteric segments: an underrecognized condition with a multifactorial etiology.

Hum Pathol 2018 07 27;77:80-87. Epub 2018 Mar 27.

Pathology and Laboratory Medicine, Albany Medical College, Albany, NY 12208, USA. Electronic address:

Microscopic ileitis has been infrequently reported in the literature with the few reported cases usually associated with concurrent microscopic colitis. Having encountered a case of collagenous ileitis involving the diverted distal limb of a loop ileostomy and sparing the proximal limb, we examined additional cases of loop ileostomy, end ileostomy, colostomy, and the accompanying diverted colorectal segment for features of microscopic ileitis and colitis. A total of 101 cases of diverted and nondiverted enteric segments were examined from 37 loop ileostomies, 16 end ileostomies, and 12 colostomies status post-Hartmann's procedure. Read More
