Collagenous and lymphocytic colitis are two inflammatory conditions of the colon that are often collectively referred to as microscopic colitis. The present report describes what is believed to be the third published case of familial microscopic colitis. A 55-year-old woman who suffered from chronic diarrhea was diagnosed with lymphocytic colitis on colonic biopsy. Subsequently, her 36-year-old daughter was diagnosed with collagenous colitis. The familial occurrence of these diseases may support an immunological hypothesis for their etiology. In addition, it supports the assumption that collagenous and lymphocytic colitis are two manifestations of the same disease process rather than two completely separate entities. The familial tendency of this disease may make a case for early colonoscopy and biopsy in relatives of patients diagnosed with microscopic colitis if they present with suggestive symptoms.

Abstract Background Microscopic colitis (MC) is a chronic inflammatory disease of the colon characterized by lymphocytic infiltration with (collagenous colitis) or without (lymphocytic colitis) the expansion of collagen fibres, and the normal macroscopic appearance of the mucosa on ileocolonoscopy. Recent studies have shown that the ileum may be involved in MC, occurring concurrently with colonic disease, however there is sparse literature on isolated lymphocytic ileitis without colitis. Aims We describe the case of isolated small bowel lymphocytosis without evidence of lymphocytic colitis to highlight the utility of random biopsies of the terminal ileum in cases where microscopic colitis is a diagnostic consideration. Methods A 70-year-old female known for cutaneous mastocytosis presented with six weeks of abdominal pain, non-bloody diarrhea, intolerance to oral intake and significant weight loss. Computed-tomography showed evidence of possible mesenteric panniculitis. Colonoscopy revealed a normal colon and normal-appearing mucosa of the terminal ileum. Random mucosal biopsies were taken to assess for microscopic colitis, with terminal ileal biopsies revealing significant lymphocytic infiltration consistent with lymphocytic ileitis. Biopsies throughout the colon revealed normal colonic mucosa without evidence of concurrent microscopic colitis. Gastroscopy was macroscopically unremarkable and random biopsies in the stomach and duodenum were negative for Helicobacter pylori and lymphocytosis. Immunostaining of the gastric, duodenal, terminal ileal and colonic biopsy specimens were negative for CD25, CD117 and tryptase, indicating the absence of gastrointestinal mastocytosis. Results The patient was diagnosed with lymphocytic ileitis and given the known response of MC to budesonide, she was treated with eight weeks of budesonide with clinical improvement leading to remission of her symptoms. Conclusions This case illustrates a rare incidence of isolated ileal microscopic ileitis without colitis that responded well to standard MC treatment, thereby underscoring the utility of random biopsies in the terminal ileum and throughout the colon when microscopic colitis is on the differential diagnosis.

Introduction: Irritable bowel Syndrome (IBS) is a functional disorder of abdominal pain or discomfort associated with altered bowel habit. Microscopic colitis is a chronic inflammatory condition associated with non bloody diarrhoea and characteristic histological finding. The subset of diarrhoea predominant IBS is having similarity in presentation with microscopic colitis. Objective: To assess the prevalence and characteristics of microscopic colitis in Diarrhoea predominant Irritable Bowel Syndrome (IBS-D). Materials and Methods: This observational study was conducted at the department of Gastroenterology, Combined Military Hospital, Dhaka during the period of January 2011 to June 2011. Initially 100 cases of diarrhoea predominant IBS who met Rome III criteria were included. Among those 100 cases, 57 were male and 43 were female. Mean age was 46 years ±2.8 SD(range 18-72). Six patients were subsequently excluded because of some macroscopic abnormalities at colonoscopy. Finally 94 patients of clinical IBS-D whose colonoscopy were normal, biopsy specimens were taken from caecum, transverse colon, descending colon, sigmoid and rectum. Microscopic colitis was diagnosed on the basis of evidence of increased intraepithelial lymphocytes of ≥20/100 inter cryptal epithelial cells and infiltration of lamina propria by mixed inflammatory cells. Overlap of other symptoms between Microscopic Colitis (MC) and IBS-D were also evaluated. Results: Among the 94 patients of clinical IBS-D, 23(24%) patients were histologically proved to have microscopic colitis. Besides Rome III criteria, there was significant overlap of other symptoms. Occasional fever and infrequent arthralgia 7% and 26% vs 4% respectively) but tenesmus, passage of excessive mucus and heart- burn were more prevalent in IBS-D than MC (35% vs 13%, 32% vs 4% and 32 vs 9% respectively). Among the 23 cases of MC, 13(57%) patients were female and 10(43%) patients were male. Mean age of microscopic colitis was 56 years ±2.6 SD (range 25-72). Regarding subtypes of microscopic colitis, 21(91%) patients had lymphocytic colitis (LC) and 2 (9%) patients had collagenous colitis (CC). Of the lymphocytic colitis 11 were female and 10 were male and of the 02 cases of collagenous colitis all were female. MC affected mostly the transverse colonie 11(48%) cases and the next common site was caecum ie 8(35%) cases. Conclusion: A good percentage of diarrhoea predominant IBS are actually having microscopic colitis. MC is more common in female and elderly persons. In all elderly patients of IBS-D full colonoscopy should be done and biopsy should be taken from multiple sites to exclude microscopic colitis.

Microscopic colitis (MC) is defined by the presence of specific histologic abnormalities in patients with diarrhea and a normal-appearing colon at endoscopy. MC can be categorized into two types: collagenous colitis (CC) and lymphocytic colitis (LC). CC is characterized by a thickened subepithelial collagen band in the colonic mucosa of at least 10 mm in thickness, whereas LC describes infiltration of the colonic epithelium with lymphocytes (intraepithelial lymphocytes), without excess collagen in the mucosa. This review of MC addresses the epidemiology, pathogenesis, etiology/genetics, diagnosis, differential diagnosis, treatment, complications, and prognosis between the two types. Tables list potential etiologic factors in MC, medications associated with MC, and treatments used for MC and evidence base. This review contains 3 tables and 55 references.

Collagenous colitis and lymphocytic colitis are newly described colitides that are only diagnosable microscopically; therefore, both are known under the umbrella term ’microscopic colitis’. This is a short review of the clinical findings, and epidemiological and basic observations of these relatively little described colitides belonging to the group of inflammatory bowel diseases.

Abstract Background and Aims Epidemiological studies suggest an increasing global incidence of microscopic colitis, including collagenous colitis and lymphocytic colitis. We aimed to investigate the incidence and prevalence of microscopic colitis in Denmark. Methods In a nationwide cohort study, we included all incident patients with a recorded diagnosis of collagenous colitis or lymphocytic colitis in the Danish Pathology Register between 2001 and 2016. Results A total of 14 302 patients with microscopic colitis—8437 [59%] with collagenous and 5865 [41%] with lymphocytic colitis—were identified during the study period. The prevalence in December 2016 was estimated to be 197.9 cases per 100 000 inhabitants. Microscopic colitis was more prevalent among females (n = 10 127 [71%]), with a mean annual incidence of 28.8, compared with 12.3 per 100 000 person-years among males. The overall mean incidence during the study period was 20.7 per 100 000 person-years. Mean age at time of diagnosis was 65 years (standard deviation [SD]:14) for microscopic colitis, 67 [SD:13] for collagenous colitis, and 63 [SD:15] for lymphocytic colitis. The overall incidence increased significantly from 2.3 cases in 2001 to 24.3 cases per 100 000 person-years in 2016. However, the highest observed incidence of microscopic colitis was 32.3 cases per 100 000 person-years in 2011. Large regional differences were found, with the highest incidence observed in the least populated region. Conclusions The incidence of microscopic colitis in Denmark has increased 10-fold during the past 15 years and has now surpassed that of Crohn’s disease and ulcerative colitis. However, incidence has stabilised since 2012, suggesting that a plateau has been reached.
