Microscopic colitis: a narrative review with clinical approach.

Minerva Gastroenterol Dietol 2019 Mar 21;65(1):53-62. Epub 2018 Nov 21.

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

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

Department of Pathology, Brigham and Women's Hospital, Boston, MA, USA.

Certain types of colitides, such as collagenous colitis, lymphocytic colitis, and ischemic colitis, have distinct histologic features that allow for a specific diagnosis. However, in most colonic biopsy specimens, a definite diagnosis cannot be established on the basis of histology alone. Thus, in most cases of colitis, it is helpful to utilize a systematic approach in order to recognize patterns of injury. Read More

Background: Microscopic colitis (MC), comprising collagenous colitis (CC) and lymphocytic colitis (LC), is a type of variation of inflammatory bowel diseases. Local T-cell infiltration in the mucosa plays a major role in MC immunopathology.

Methods: To understand diversity and clonality of infiltrating T cells, we analyzed the T-cell receptor beta (TCRβ) chains in colonic biopsies of MC, ulcerative colitis (UC), and their remission counterparts (CC/LC-HR [histological remission] or UC-R [remission]) compared with patients with noninflamed colons using next-generation sequencing.

Over 90% of cases of Microscopic Colitis can be diagnosed by performing a short colonoscopy.

Clin Res Hepatol Gastroenterol 2017 Jun 16;41(3):333-340. Epub 2017 Feb 16.

Montfermeil, France.

Aims: To determinate the topographical distribution of key diagnostic histological features of lymphocytic colitis (LC) and collagenous colitis (CC) and to establish what correlations may exist between the histological findings and the causes and severity of MC.

Patients And Methods: Patients with MC were included in a prospective multicentre French study from September 2010 to October 2012. MC was diagnosed by performing total colonoscopy with multiple biopsies of the rectum and colon collected in separate jars and analyzed separately for each site (descending and sigmoid colon, transverse colon, ascending colon).

Drug Exposure and the Risk of Microscopic Colitis: A Critical Update.

Drugs R D 2017 Mar;17(1):79-89

Department of Gastroenterology, Hospital General de Tomelloso, Vereda de Socuéllamos s/n, Tomelloso, 13700, Ciudad Real, Spain.

A variety of luminal antigens, including a wide range of drugs, have been associated with the still little-known pathophysiology of microscopic colitis (MC), with variable evidence suggesting causality. This article aims to review the aspects related to drugs as potential triggers of MC; to discuss the most commonly identified associations between drugs and MC; and to analyze the limitations of the studies currently available. A literature search was performed in PubMed combining the search terms 'drug exposure', 'drug consumption', and 'risk factors' with 'microscopic colitis', 'lymphocytic colitis', and 'collagenous colitis', with no language restrictions.

Reduced IL-37 Production Increases Spontaneous Chemokine Expressions in Colon Epithelial Cells.

Dig Dis Sci 2017 05 2;62(5):1204-1215. Epub 2017 Jan 2.

School of Medical Sciences, Faculty of Medicine and Health, Örebro University, 70182, Örebro, Sweden.

Background And Aim: Microscopic colitis, comprising collagenous colitis and lymphocytic colitis, is a common cause of chronic diarrhea. Previously, we showed enhanced chemokine productions in microscopic colitis patients, indicating dysregulated immune cell chemotaxis in the immunopathogenesis. We also showed decreased mRNA of IL-37, mainly regarded as an anti-inflammatory cytokine, in the colonic mucosa of these patients, potentially an important factor for the chronicity of the colitis.

Microscopic colitis: A literature review.

Rev Assoc Med Bras (1992) 2016 Dec;62(9):895-900

MD from Emescam, Vitória, ES, Brazil.

Microscopic colitis (MC) refers to chronic inflammation of the colon which is characterized by histologic changes at the level of a radiologically and endoscopically normal mucosa. It is a common cause of chronic non-bloody diarrhea that occurs primarily in older individuals; however, there are few studies in the literature with strong scientific evidence compared to other inflammatory bowel diseases (IBD), which limits the knowledge of physicians and pathologists. This article aims to review the information on MC, describing diagnostic methods and drugs available for treatment. Read More

Development of a Microscopic Colitis Disease Activity Index: a prospective cohort study.

Gut 2018 03 13;67(3):441-446. Epub 2016 Dec 13.

Divisions of Gastroenterology and Hepatology, Mayo Clinic, Rochester, Minnesota, USA.

Objective: Microscopic colitis (MC) is a common cause of chronic diarrhoea, often with additional symptoms. No validated instruments exist to assess disease activity in MC, making it difficult to compare efficacy of treatments between clinical trials. We aimed to identify clinical features that independently predicted disease severity and create a Microscopic Colitis Disease Activity Index (MCDAI). Read More

Towards a new paradigm of microscopic colitis: Incomplete and variant forms.

World J Gastroenterol 2016 Oct;22(38):8459-8471

Danila Guagnozzi, Department of Gastroenterology, Hospital Universitario Vall d'Hebron, 08035 Barcelona, Spain.

Microscopic colitis (MC) is a chronic inflammatory bowel disease that has emerged in the last three decades as a leading cause of chronic watery diarrhoea. MC classically includes two main subtypes: lymphocytic colitis (LC) and collagenous colitis (CC). Other types of histopathological changes in the colonic mucosa have been described in patients with chronic diarrhoea, without fulfilling the conventional histopathological criteria for MC diagnosis.
