1/180. 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 = colitis (Clic here for more details about this article) |
2/180. 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 = 1.3333333333333keywords = colitis (Clic here for more details about this article) |
3/180. 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 = 0.83333333333333keywords = colitis (Clic here for more details about this article) |
4/180. 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 = 1keywords = colitis (Clic here for more details about this article) |
5/180. clostridium difficile diarrhea and colitis: a clinical overview.Infection with toxin-producing strains of clostridium difficile is common and potentially life-threatening. It occurs mostly in patients in the hospital or nursing home who are taking or have recently taken antibiotics. Two toxins, A and B, damage the colonic mucosa, resulting in symptoms ranging from mild diarrhea to bloody diarrhea with fever and abdominal pain, colitis, or even pseudomembranous colitis. Severe cases may involve dehydration, toxic megacolon, or colonic perforation. This article reviews the microbiology, epidemiology, clinical manifestations, diagnosis, treatment, and prevention of this disease.- - - - - - - - - - ranking = 1keywords = colitis (Clic here for more details about this article) |
6/180. Chronic microscopic enterocolitis with severe hypokalemia responding to subtotal colectomy.The authors present the first case report of a 50-year-old woman with a 33-year history of severe, chronic watery diarrhea and hypokalemia secondary to chronic active microscopic enterocolitis with patterns similar to lymphocytic colitis but with acute cryptitis and terminal ileum involvement microscopically. The progressive nature of her illness resulted in multiple hospital admissions secondary to hypokalemia with subsequent chronic renal failure. High continuous doses of oral potassium supplements failed to correct the hypokalemic episodes. After subtotal colon resection, the patient made a marked clinical improvement with normal serum potassium levels without receiving potassium supplementation.- - - - - - - - - - ranking = 1keywords = colitis (Clic here for more details about this article) |
7/180. 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 = 3.3333333333333keywords = colitis (Clic here for more details about this article) |
8/180. Diarrhoea and colitis associated with antibiotic treatment.Sixteen cases of colitis developing within twenty-one days of antibiotic therapy are reported. There was a wide range of disease severity. lincomycin and clindamycin were implicated in twelve. The colitis was of two pathological patterns pseudomembranous colitis and "non-specific" colitis. There is a relative sparing of the rectum in some cases making the diagnosis more difficult on sigmoidoscopy.- - - - - - - - - - ranking = 1.3333333333333keywords = colitis (Clic here for more details about this article) |
9/180. thymoma-associated autoimmune enteropathy. A report of two cases.Autoimmune enteropathy is an increasingly recognized cause of severe protracted diarrhea, usually affecting infants and children predisposed to autoimmune phenomena. Although this may be a common cause of diarrheal illness, it is scarcely recognized in the American literature. In association with thymoma, a case of so-called graft-vs-host-like colitis and 2 cases of chronic diarrhea associated with thymoma were reported, but, to our knowledge, no cases of autoimmune enteropathy have been reported as such. We describe 2 adults with autoimmune enteropathy found in association with a thymoma.- - - - - - - - - - ranking = 0.16666666666667keywords = colitis (Clic here for more details about this article) |
10/180. 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 = 1.3333333333333keywords = colitis (Clic here for more details about this article) |
