1/174. 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.- - - - - - - - - - ranking = 1keywords = watery diarrhea, diarrhea (Clic here for more details about this article) |
2/174. 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.- - - - - - - - - - ranking = 1.0323959304993keywords = watery diarrhea, diarrhea (Clic here for more details about this article) |
3/174. 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.- - - - - - - - - - ranking = 0.064791860998609keywords = diarrhea (Clic here for more details about this article) |
4/174. 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.- - - - - - - - - - ranking = 1.0323959304993keywords = watery diarrhea, diarrhea (Clic here for more details about this article) |
5/174. association of lymphocytic colitis with linear IgA dermatosis.The case of a 66-year-old female patient is presented, who suffered from chronic watery diarrhea. In addition, she developed linear IgA dermatosis after oral treatment of a presumed yeast infection with nystatin. To evaluate the reason for her diarrhea, colonoscopy was performed. The macroscopic aspect of the colon mucosa was described as normal with no specific alterations for chronic inflammatory bowel disease or for bacterial infections. In contrast, the histologic examination revealed the typical characteristics of lymphocytic colitis. This disease is thought to be caused by immunological reactions against as yet unknown luminal antigens. After treatment with steroids and dapsone the diarrhea as well as the skin disease disappeared. To our knowledge, the present report describes for the first time the association of linear IgA dermatosis with lymphocytic colitis after oral treatment with nystatin. A possible causative link between these two disease entities is discussed.- - - - - - - - - - ranking = 1.0647918609986keywords = watery diarrhea, diarrhea (Clic here for more details about this article) |
6/174. Successful treatment of cytomegalovirus colitis with ganciclovir in a patient with adult T cell leukemia lymphoma: case report.An 84-year-old patient with adult T cell leukemia lymphoma (ATLL) developed diarrhea on day 5 of chemotherapy and was diagnosed with cytomegalovirus (CMV) colitis. sigmoidoscopy revealed multiple superficial erosions surrounded by a flare. Computed tomography (CT) and ultrasonogram of the abdomen revealed marked thickening of the colonic mucosa. There were 186 CMV antigen-positive leukocytes per 31,000 white blood cells (WBC). A colonic biopsy specimen showed typical CMV nuclear inclusions. Immunohistological study of the specimen was positive for CMV antigen. Administration of ganciclovir (DHPG) 500 mg/day for 14 days improved the diarrhea and other symptoms. On day 30 of the chemotherapy, the patient developed diarrhea again but was diagnosed with pseudomembranous colitis instead of CMV colitis. At that time, CMV antigenemia and a histologic study for CMV were negative. The stool was positive for clostridium difficile toxin antigen. ATLL patients are believed to be immunocompromised hosts and often develop opportunistic infections such as CMV infection. Most suffer from CMV pneumonia at the end of their course of therapy. Few gastrointestinal (GI) CMV infections are seen in ATLL patients and details of CMV colitis have never been reported. When an ATLL patient develops diarrhea that barely responds to conventional therapy, CMV colitis and pseudomembranous colitis should be listed in the differential diagnosis.- - - - - - - - - - ranking = 0.12958372199722keywords = diarrhea (Clic here for more details about this article) |
7/174. Collagenous gastrobulbitis and collagenous colitis. Case report and review of the literature.A case is reported of collagenous gastrobulbitis on collagenous colitis in a 57-year-old woman with a 6-month history of watery diarrhea. Low serum levels of total proteins and albumin and increased fecal elimination of alpha1-antitrypsin were the only abnormal laboratory test results. biopsy specimens from the colon, rectum, antrum, fundus, and duodenal bulb showed a thick subepithelial band composed of ultrastructurally normal collagen immunohistochemically negative for collagen IV and laminin. The diarrhea resolved with prednisone and responded to this treatment after a relapse 6 months later. One year later the patient developed severe alimentary intolerance and secondary weight loss. This symptom also responded to the same treatment. However, the collagen deposition did not disappear in the second biopsy samples of colonic and gastric mucosa. Only six cases have been previously reported with gastric and/or duodenal subepithelial collagenous deposition. Four were associated with collagenous colitis. One of these presented a subepithelial collagenous band in the terminal ileum. All these features suggest that this collagen deposition may affect the entire digestive tract with variable intensity, extension, and symptoms.- - - - - - - - - - ranking = 1.0323959304993keywords = watery diarrhea, diarrhea (Clic here for more details about this article) |
8/174. Microscopic colitis syndrome: lymphocytic colitis and collagenous colitis.Microscopic colitis is a syndrome consisting of chronic watery diarrhea, a normal or near-normal gross appearance of the colonic lining, and a specific histological picture described as either lymphocytic colitis or collagenous colitis. Since its initial descriptions a quarter of a century ago, microscopic colitis has become a frequent diagnosis in patients with chronic diarrhea. Understanding of the cause and pathogenesis of microscopic colitis remain incomplete, but potentially important clues have been discovered that shed light on predisposing factors. In particular, specific HLA-DQ genotypes may be permissive for the development of microscopic colitis, and suggest a linkage to the pathogenesis of celiac sprue. Although the differential diagnosis of chronic watery diarrhea is broad, the diagnosis of microscopic colitis is straightforward, involving endoscopic inspection of the colonic mucosa and proper pathologic interpretation of biopsy specimens. As the limitations of drugs ordinarily used for other forms of inflammatory bowel disease are being recognized, new approaches, such as the use of bismuth subsalicylate, are being evaluated. The prognosis of patients with microscopic colitis syndrome remains good, and symptomatic improvement can be expected in most patients.- - - - - - - - - - ranking = 2.0323959304993keywords = watery diarrhea, diarrhea (Clic here for more details about this article) |
9/174. Lymphocytic colitis, induced by ticlopidine.Lymphocytic colitis is a chronic inflammatory colonic disease characterized by watery diarrhea and a dense infiltration of the colonic mucosa with lymphocytes. The etiology is unknown but an immune reaction to various immunostimulatory agents including pathogenic or commensal bacteria, products of bacterial metabolism of dietary degradation, or antigens derived directly from the diet, and autoimmune phenomena are discussed. We observed a patient with all features of lymphocytic colitis characterized by a prominent intraepithelial T-cell component. The colitis resolved completely when therapy with ticlopidine--an agent inhibiting platelet aggregation--was stopped. This observation suggests that medical history concerning drug ingestion may reveal the etiology of lymphocytic colitis and allows cure of this otherwise difficult to treat disorder.- - - - - - - - - - ranking = 1keywords = watery diarrhea, diarrhea (Clic here for more details about this article) |
10/174. colitis may be part of the antiepileptic drug hypersensitivity syndrome.PURPOSE: To show that colitis may be part of the antiepileptic hypersensitivity syndrome. methods: Description of two case histories. RESULTS: The first patient was a 47-year-old man who developed fever, lymphadenopathy, influenza-like symptoms, facial edema, skin rash and diarrhea after 3 weeks of carbamazepine (CBZ) treatment. laparotomy because of severe abdominal pain 2 weeks later showed severe colitis with perforations. The second patient was a 41-year-old woman who developed fever, diarrhea, and skin rash 4 weeks after start of CBZ treatment. A colon biopsy confirmed colitis. Stool examinations did not show pathogenic microorganisms, and there was no evidence of Crohn's disease or ulcerative colitis. Both patients had elevated liver enzymes, peripheral eosinophilia, and eosinophils in the infiltrate of the colon. CONCLUSIONS: In view of the close temporal relation between start of CBZ intake and development of colitis, the presence of fever, lymphadenopathy, and rash, and improvement after discontinuation of CBZ, we conclude that the two patients developed an AED hypersensitivity syndrome. Our case histories demonstrate that severe colitis may be part of this syndrome.- - - - - - - - - - ranking = 0.064791860998609keywords = diarrhea (Clic here for more details about this article) |
