[Collagen gastroenterocolitis].

INTRODUCTION: Collagenous gastroenterocolitis is a recently known rare cause of chronic diarrhoea, that raises numerous nosological and diagnostic problems. OBSERVATION: A 41 year-old woman was hospitalised for severe diarrhoea, diagnosed as collagenous gastroenterocolitis. Gastroscopy and ileocolonoscopy were macroscopically normal, but a 20 to 40 microns thick sub-epithelial collagenous band was revealed in the gastric, duodenal and colic biopsies. Parenteral nutrition and treatment with salazopyrine and prednisolone progressively normalised the transit. Three months later, only a 30 microns colic mucosa collagenous band persisted. All the biopsies taken during control gastro-colonoscopy 2 years later were histologically normal. After 5 years follow-up and absence of treatment, the patient no longer presented diarrhoea or biological abnormality. COMMENTS: This exceptional observation is a reminder that sub-epithelial collagen deposits are not always limited to the colon and therefore justify, in patients with collagenous colitis, systematic gastro-duodenal and ileum biopsies.

Microscopic colitis.

Microscopic colitis is an idiopathic chronic inflammatory bowel disease presenting with watery diarrhea. While colonoscopy and radiology findings are normal, the colon shows striking pathologic findings, including lymphocytic colitis and collagenous colitis. The clinical course is usually benign with sustained remission. Recent medical evidence shows that bismuth and budesonide are effective treatments.

[Diarrhea].

A 54-year-old man had recurrent watery diarrhea with up to 10 stools per day for 4 years. The initial evaluation including coloscopy did not disclose a pathologic finding. The symptoms subsided initially after four weeks. Three years later massive watery diarrhea recurred with up to fifteen daily stools. A reevaluation of the patient disclosed the diagnosis of collagen colitis in the colonic biopsy.

Complete histological resolution of collagenous sprue.

A 65-year-old woman developed a watery diarrhea syndrome with collagenous colitis. Later, weight loss and hypoalbuminemia were documented. This prompted small bowel biopsies that showed pathological changes of collagenous sprue. An apparent treatment response to a gluten-free diet and prednisone resulted in reduced diarrhea, weight gain and normalization of serum albumin. Later repeated biopsies from multiple small and large bowel sites over a period of over three years, however, showed reversion to normal small intestinal mucosa but persistent collagenous colitis. These results indicate that collagenous inflammatory disease may be a far more extensive process in the gastrointestinal tract than is currently appreciated. Moreover, collagenous colitis may be a clinical signal that occult small intestinal disease is present. Finally, collagenous sprue may, in some instances, be a completely reversible small intestinal disorder.

Collagenous and lymphocytic colitis: a clinical and histopathological review.

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.

Familial occurrence of microscopic colitis: a report on five families.

BACKGROUND: The etiology and pathogenesis of microscopic colitis is unknown. Whether genetic predisposition is of importance, as in many other gastrointestinal diseases, is unknown. Familial occurrence of collagenous colitis has earlier been reported only in two families. METHODS: Familial occurrence of microscopic colitis was searched for in a Swedish national microscopic colitis register. RESULTS: Familial occurrence of microscopic colitis was identified in five families. In all families a sister-sister relationship was found. Two sisters with collagenous colitis had been living apart in different Nordic countries for many years before developing the disease. In one pair, the smoking sister had collagenous colitis and the never smoking sister had lymphocytic colitis. CONCLUSIONS: Considering the relative rarity of microscopic colitis, these findings indicate that a genetic predisposition may be of importance.

Microscopic colitis.

Microscopic colitis has 2 main subtypes, collagenous colitis and lymphocytic colitis, that are similar clinically and histologically and are distinguished mainly by the presence or absence of a thickened subepithelial collagen band. Microscopic colitis accounts for approximately 10% of chronic watery diarrhea and may be associated with abdominal pain and mild weight loss. It is typically diagnosed in the sixth to eighth decade of life, and there is a female pre-dominance that is more striking for collagenous colitis than for lymphocytic colitis. Endoscopic and radiographic findings of the colon appear normal. Diagnosis is made by colonic biopsy, which shows an intraepithelial lymphocytosis and a mixed inflammatory infiltrate in the lamina propria. Many potential treatments have been reported, but few have been subjected to controlled treatment trials. A stepwise approach to therapy often leads to satisfactory control of symptoms.

Lymphocytic enterocolitis in patients with 'refractory sprue'.

We describe a patient with refractory sprue with malabsorption, a flat small-bowel biopsy specimen unresponsive to a gluten-free diet, and colonic biopsy specimens consistent with lymphocytic (microscopic) colitis. To investigate further the relation between celiac disease and lymphocytic or collagenous colitis (a similar and possibly related entity), we examined colorectal and small-bowel biopsy specimens in patients indexed histologically as having celiac disease who have been seen at The Johns Hopkins Hospital since 1958. Of 135 indexed patients, 21 had colorectal biopsies. Colorectal biopsy specimens were abnormal in 7 of the 21 patients. Four patients had biopsy specimens resembling lymphocytic colitis, 2 patients had acute colitis, and another patient had both lymphocytic and acute colitis. No patients had collagenous colitis. Three of the patients with lymphocytic colitis and celiac-like changes of the small bowel never responded to a gluten-free diet and may represent a distinctive panintestinal disease for which the term "lymphocytic enterocolitis" with malabsorption is proposed.

Interchange between collagenous and lymphocytic colitis in severe disease with autoimmune associations requiring colectomy: a case report.

BACKGROUND: Collagenous colitis and lymphocytic colitis present with a similar clinical picture. Whether these conditions are separate entities or whether they represent different pathological stages of the same condition is an unresolved issue. PATIENT: This is a case of collagenous colitis following a fulminant course in which a colectomy was necessary. In the operative specimen the thickened collagen plate, which had been present only two weeks preoperatively had been lost and the pathology was of a lymphocytic colitis. Six months postoperatively this patient developed a CREST syndrome and primary biliary cirrhosis. CONCLUSIONS: This case shows the lability of the collagen plate and the common ground between collagenous and lymphocytic colitis, and presents evidence that these two conditions are different manifestations of the same disease. It also describes for the first time an association between collagenous colitis and CREST syndrome and primary biliary cirrhosis.

[Evolution and treatment response in microscopic colitis].

AIM: To study the clinical characteristics, treatment response and evolution in patients with microscopic colitis. MATERIAL AND METHODS: We performed a retrospective analysis of 24 patients (15 with collagenous colitis and 9 with lymphocytic colitis). Clinical and diagnostic features, treatment response and evolution according to the presence of maintenance therapy were evaluated. RESULTS: The mean age of the patients was 59.7 years and most were male. Nine patients took non-steroidal anti-inflammatory drugs (NSAID). No significant association was found with other drugs. Four patients presented associated rheumatological disease. Most patients presented insidious-onset diarrhea without pathological products, which was frequently associated with other symptoms (abdominal pain, bloating, weight loss, asthenia, tenesmus, and incontinence). Seven patients showed a slight increase in globular sedimentation rate. Fat in stools and radiological investigations (transit and opaque enema) were normal in patients who underwent these tests. Endoscopy revealed non-specific alterations in 42% of the patients while results were normal in the remaining patients. One patient showed clinical improvement on withdrawal of NSAIDs and 4 patients improved spontaneously. Clinical response was achieved in 7 of 13 patients treated with antimotility drugs, in 8 of 9 patients treated with salicylates, in 3 treated with oral corticoids, in 1 treated with cholestyramine and in 1 treated with topical budesonide. Nineteen patients required no maintenance therapy, 4 were administered salicylates and 1 was administered cholestyramine. After a mean follow-up of 42 months, evolution was chronic and intermittent in 14 patients and chronic and continuous in 1; 9 patients presented a single episode. No significant differences were found between patients administered maintenance therapy and those who were not or between collagenous colitis and lymphocytic colitis in the parameters analyzed. CONCLUSIONS: Microscopic colitis constitutes a group of diseases characterized by chronic diarrhea, few systemic effects and minimal radiological and/or endoscopic alterations. Evolution is characterized by recurrent episodes, with good response to treatment with cholestyramine, salicylates or corticoids when required.

Hyposplenism, antiendomysial antibodies and lymphocytic colitis in collagenous sprue.

A 66-year-old woman was seen repeatedly over a decade to remove recurrent colonic adenomas and investigate episodes of watery diarrhea. Although the diarrhea was believed to be due to lymphocytic colitis, she developed weight loss, hypoproteinemia and hyposplenism that resulted in further studies, specifically to exclude celiac disease. Small intestinal biopsies, however, showed severely 'flattened' villous architecture with trichrome-positive subepithelial collagenous deposits, characteristic of collagenous sprue. Antiendomysial antibodies, known serological markers of celiac disease, were also detected. While collagenous sprue has been considered a distinct small intestinal disorder, the constellation of clinical and pathological findings in this patient suggests a close link with adult celiac disease.

Collagenous, microscopic and lymphocytic colitis. An evolving concept.

Collagenous colitis and lymphocytic colitis (previously described as microscopic colitis) are two newly recognised forms of colitis. Both have generated much controversy and continue to do so; their aetiology and pathogenesis are unresolved and their association with a variety of immune-related disorders is intriguing. Response to available therapeutic modalities is often disappointing. The possible relationship or overlap between these two conditions remains a controversial issue. The aim of this review is essentially to present an overview of collagenous colitis and lymphocytic colitis and to propose an unifying concept with an adapted terminology.

A new method for the quantification of neutrophil and eosinophil cationic proteins in feces: establishment of normal levels and clinical application in patients with inflammatory bowel disease.

OBJECTIVES: The aims of this study were 1) to develop a valid method for the measurement of the eosinophil proteins eosinophil cationic protein (ECP) and eosinophil protein X (EPX) and neutrophil proteins myeloperoxidase and human neutrophil lipocalin (HNL) in feces and 2) to investigate their potential role as disease activity markers in inflammatory bowel disease (IBD). METHODS: Feces samples were obtained from 44 apparently healthy individuals (HIs), 18 patients with IBD (11 with ulcerative colitis [UC] and seven with Crohn's disease [CD]), and three with collagen colitis. The granulocyte markers were measured using immunoassays in supernatants from processed feces. RESULTS: ECP, myeloperoxidase, and, to a lesser degree, EPX and HNL were bound to the solid part of feces. However, feces homogenized in an extraction buffer containing the cationic detergent N-cetyl-N,N,N-trimethylammonium bromide allowed an efficient recovery of the proteins (i.e., up to 100-fold increased levels compared to homogenization in saline). All four proteins were stable for at least 7 days at +6 degrees C and at least 3 days at +22 degrees C. The normal fecal geometric mean (95th percentile) levels of ECP, EPX, myeloperoxidase, and HNL were estimated to be, respectively, 1.69 microg/g (6.41), 0.57 microg/g (1.72), 3.54 microg/g (8.77), and 1.97 microg/g (4.91). Markedly increased feces levels of all markers (p < 0.0002), compared to HIs and CD patients, were observed in UC. However, the marker levels in CD patients were significantly increased relative to HIs (p < 0.05 to p < 0.0002). Increased levels of HNL and myeloperoxidase were also observed in the three collagen colitis patients. The discriminative capability between UC patients and HIs was somewhat superior for EPX and myeloperoxidase. CONCLUSIONS: The method described here takes into account the molecular properties of the granule proteins and the heterogeneity in feces consistency, which is a prerequisite for a valid and reproducible measurement of cationic granule proteins. We suggest that EPX and myeloperoxidase, when applied in IBD, are the best eosinophil and neutrophil markers for studying GI inflammation.

Acute radiation colitis in patients treated with short-term preoperative radiotherapy for rectal cancer.

The histopathologic features of acute radiation-induced colitis in humans have been described in occasional, >20-year-old studies, but they have not been analyzed in detail. We characterize such findings in 34 patients with rectal cancer who underwent surgery a few days after preoperative irradiation with 25 Gy given over 5-7 days, and we compare the results to the histopathologic features detected in 18 patients treated by a conventional preoperative irradiation protocol consisting of 45 Gy during 5 weeks followed by surgery after a time interval of at least 3 weeks. Short-term preoperative irradiation therapy generally induced severe mucosal inflammation characterized by increased cellularity of the lamina propria, prominent eosinophilic infiltrates, crypt disarray, surface and crypt epithelial damage, nuclear abnormalities, and presence of apoptotic bodies in the crypt epithelium. These histopathologic features were absent or detected only occasionally in the patient group treated according to the long-term preoperative irradiation protocol. Despite acute severe inflammation, none of the patients treated by short-term irradiation developed perioperative complications. These observations indicate that acute radiation colitis may remain clinically silent and resolve spontaneously within a few weeks after irradiation. Given the widening acceptance of short-term preoperative irradiation protocols for rectal cancer, pathologists should be aware of the rather characteristic histologic findings of acute radiation colitis and avoid unnecessary concern of clinicians. The differential diagnosis includes infectious colitis, collagenous and ischemic colitis, nonsteroidal anti-inflammatory drug-associated colitis, and chronic idiopathic inflammatory bowel disease.
