Microscopic colitis, comprising collagenous colitis and lymphocytic colitis, is characterised clinically by chronic watery diarrhoea, 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 predominance in collagenous colitis. The aetiology is unknown. Abdominal pain, weight loss, fatigue, and faecal incontinence are common symptoms in addition to chronic diarrhoea that impair the health-related quality of life of the patient. There is an association to other autoimmune disorders such as celiac disease, diabetes mellitus, thyroid disorders and arthritis. Budesonide is the best-documented short-term treatment, but the optimal long-term strategy needs further study. The long-term prognosis is good and the risk of complications including colonic cancer is low.

Microscopic colitis, comprising collagenous colitis and lymphocytic colitis, is a common cause of chronic diarrhea. It is characterized clinically by chronic watery diarrhea and a macroscopically normal colonic mucosa where diagnostic histopathological features are seen on microscopic examination.

The etiology is unknown. Chronic diarrhea, abdominal pain, weight loss, fatigue, and fecal incontinence are common symptoms that impair the health-related quality of life of the patient. There is an association with other autoimmune disorders, such as celiac disease, thyroid disorders, diabetes mellitus, and arthritis. Budesonide is the best-documented treatment, both short-term and long-term. Recurrence of symptoms is common after withdrawal of successful budesonide therapy, and the optimal long-term treatment strategy needs further study. The long-term prognosis is good, and the risk of complications including colon cancer is low. We review the epidemiology, clinical features, diagnosis and treatment of microscopic colitis.

Microscopic colitis (MC) is a common cause of chronic diarrhea. The 2 most frequent forms of MC are collagenous colitis and lymphocytic colitis. Over the past years, the incidence and prevalence of microscopic colitis are rising and this is largely attributed to a greater awareness, and concomitantly an increasing number of diagnoses. Patients with microscopic colitis report watery, nonbloody diarrhea of chronic course, abdominal pain, weight loss, and fatigue that may impair patient's health-related quality of life. The underlying mechanisms involved in the pathogenesis of microscopic colitis remain unspecified but is probably multifactorial. Collagenous colitis and lymphocytic colitis may represent specific mucosal responses to different luminal agents in predisposed individuals, resulting in an uncontrolled immune response. Genetic predisposition, altered modulation of cytokines and miRNAs, and aberrant response to drugs seem to be involved in the development of MC. Despite the progress of knowledge, still many questions remain unsolved regarding the etiology, pathophysiology, and optimal management of MC. This review gives an update on the immunological aspects of collagenous colitis and lymphocytic colitis.
