1/699. Lymphocytic colitis: a clue to an infectious trigger.

    We present a 19-year-old patient who was admitted for evaluation of prolonged watery diarrhea. Previous study showed one stool culture positive for campylobacter jejuni, which was treated with appropriate antibiotics with no response. She underwent colonoscopy with multiple biopsies, which led to a diagnosis of lymphocytic colitis. We believe that the patient's disease was due to the infectious process, which triggered an autoimmune response and caused the lymphocytic colitis. ( info)

2/699. CT findings of glutaraldehyde colitis: a report of two cases.

    The CT findings of two cases of gluteraldehyde colitis following flexible colonoscopy with normal results are described. Although the CT findings are non-specific, the diagnosis can be suggested by the radiologist who is aware of the previous endoscopy. ( info)

3/699. Therapy of prednisone-refractory collagenous colitis with budesonide.

    Collagenous colitis is a rare cause of chronic watery diarrhea. No effective standard treatment has yet been established. Based upon anecdotal reports some anti-inflammatory and symptomatic drugs seem to have some therapeutic efficacy. prednisone is widely believed to be the most effective treatment. Here we describe three female patients with histologically confirmed collagenous colitis refractory to therapy with prednisone. Each had received prednisone with a high starting bolus and lower dose maintenance therapy for their disease. However, definite clinical remission could not be achieved. After the administration of 3 x 3 mg/day controlled ileal release (CIR) capsules of budesonide the symptoms resolved immediately. The mean follow-up after beginning budesonide was 11 months (range 7-18). Two patients are still on budesonide. One had had a quick relapse of diarrhea after stopping her treatment. budesonide therapy was therefore resumed. She has remained symptom-free on a lower daily dose of 2 x 3 mg/day budesonide. One patient has been in remission for more than 1 year after a 3-month course of budesonide. budesonide is a topically acting steroid with rapid absorption, high receptor affinity, and low systemic bioavailability, thus causing almost no side effects. As yet only few case reports have been published on the use of budesonide for collagenous colitis. We present here the first three cases of prednisone refractory collagenous colitis successfully treated with budesonide. ( info)

4/699. cytomegalovirus colitis in the immunocompetent host: an overview.

    This paper describes 2 immunocompetent patients with cytomegalovirus colitis and reviews all previously reported cases (n = 13). Affected patients were generally older (69.13 /-15.62 y-old) with probable reactivation (n = 8) or younger (43.86 /-19.73 y-old) with probable primary infection (n = 7). The onset of illness was found to be hospital-associated in 4 (50.0%) reactivation cases and 1 (14.3%) primary case. Presenting manifestations included diarrhoea (86.7%), fever (80.0%), gastrointestinal bleeding (66.7%) and abdominal pain (60.0%). endoscopy showed erosive colitis with multiple (n = 11; 73.3%) or single ulcers (n = 2, 13.3%); biopsy was diagnostic in 12/13 (92.3%) patients. Complications included massive haemorrhage (13.3%), toxic megacolon (13.3%), perforation (13.3%) and protracted inflammatory bowel disease (20.0%; exclusively in primary-infection). The mortality rate was 26.7%. Antiviral-agents were given in 8 (53.3%) cases; assessment of treatment-efficacy was not possible. In conclusion, cytomegalovirus colitis in the immunocompetent-host is a rare but potentially severe erosive disease with significant morbidity. It may occur during primary infection or reactivation; the diagnosis requires careful histopathological examination and the benefit of antiviral-therapy is unknown. ( info)

5/699. Emergency surgery for generalized peritonitis caused by cytomegalovirus colitis in a patient with AIDS.

    cytomegalovirus infection of the colon is a late and severe complication in human immunodeficiency virus patients. Despite availability of medical treatment, occasional life-saving emergency surgery must be performed. The controversial surgical aspects of treatment are discussed based upon an unusual case of aseptic generalized peritonitis without perforation. The feasibility and value of limited resection are emphasized. ( info)

6/699. Linear IgA disease associated with lymphocytic colitis.

    A 66-year-old woman presented with a bullous skin eruption and chronic diarrhoea. Lesional skin showed subepidermal blistering, and direct immunofluorescence of perilesional skin revealed linear deposits of IgA at the dermoepidermal junction, establishing a diagnosis of linear IgA disease (LAD). Chronic watery diarrhoea complicated by substantial loss of body weight preceded the skin eruption for several months. On endoscopy, the colon appeared macroscopically normal. On histology, the colon mucosa showed increased numbers of intraepithelial lymphocytes and infiltrates of mononuclear cells in the lamina propria, indicative of lymphocytic colitis. Treatment with methylprednisolone and dapsone led to complete clearing of the bullous skin eruption and marked improvement of the patient's diarrhoea. Gastrointestinal disorders such as lymphocytic colitis have rarely been reported in patients with LAD. Whether the simultaneous occurrence of these two diseases is coincidental or due to related pathogenetic mechanisms remains to be seen. ( info)

7/699. cytomegalovirus colitis in individuals without apparent cause of immunodeficiency.

    cytomegalovirus infection is usually reported in immunocompromised patients. In this study, apparently immunocompetent patients with cytomegaloviral colitis were reviewed. Records with a diagnosis of cytomegaloviral colitis from January 1989 to June 1996 were retrieved for analysis. Ten patients were included (median age 70 yr). The major presenting symptoms were diarrhea and hematochezia. Ulceration was the main macroscopic finding. Rectal bleeding was mostly self-limiting. Three patients developed local complications (rectovaginal fistula in two; rectal stricture in one). In the two patients with rectovaginal fistula, lymphocytes subsets and proliferative response were entirely normal. In the other patient, low B lymphocyte count and low response to mitogen were demonstrated. However, the immunoglobulins were not suppressed and rectal biopsies revealed noncaseating granulomas, suggesting activated cell-mediated immunity. In conclusion, a high index of suspicion is crucial for early diagnosis of cytomegaloviral colitis in patients with bloody diarrhea, even though obvious evidence of immunodeficiency is lacking.

8/699. Collagenous gastritis and collagenous colitis: a report with sequential histological and ultrastructural findings.

    The case is reported of a young adult man with collagenous gastritis, an extremely rare disorder with only three case reports in the English literature, who subsequently presented with collagenous colitis. Sequential gastric biopsies showed a notable increase in thickness of the subepithelial collagen band. Ultrastructural study of gastric and rectal mucosa showed the characteristic subepithelial band composed of haphazardly arranged collagen fibres, prominent degranulating eosinophils, and activated pericryptal fibroblasts.

9/699. 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.

10/699. Biclonal lymphoplasmacytic immunocytoma associated with Crohn's disease.

    A 33-year-old man with a 4-year history of Crohn's disease presented with marked ascites and an abdominal tumor. Two M-protein peaks, immunoglobulin (Ig) G-kappa and IgA-kappa, were detected in the serum. Neoplastic lymphoplasmacytic cells were infiltrated in the bone marrow and ascites. Histological examination of the abdominal tumor showed marked proliferation of lymphoplasmacytic cells that were positive for either IgG or IgA. Moreover, dna sequences of the expressed IgG and IgA genes were different in the complementarity-determining region 3. These results suggest that chronic inflammation in Crohn's disease contributes to the simultaneous development of biclonal lymphoplasmacytic immunocytoma of the small intestine. ( info)
