A retrospective study was performed to compare the diagnostic accuracy of high-quality double-contrast barium enema (DCBE) against gold standard colonoscopy in 288 patients with suspected lower gastrointestinal bleeding who went through both examinations. Colonoscopy detected the potential cause of bleeding in 99 patients (100%); in order of frequency: polyps greater than or equal to 1 cm (N = 47; 48%), carcinoma (N = 21; 21%), inflammatory bowel disease (IBD) (N = 15; 15%), solitary ulcers (N = 6; 6%), other types of colitis (N = 5; 5%), angiodysplasia (N = 3; 3%), and stenosis (N = 2; 2%). DCBE diagnosed 88 cases (89%) and missed 11 consisting of IBD (N = 4), angiodysplasia (N = 3), solitary ulcers (N = 3), and polyps (N = 1). The overall sensitivity and specificity of DCBE was 0.89 and 0.97, respectively. The sensitivity for carcinoma, polyps, and IBD was 1.00, 0.98, and 0.73, respectively. We conclude that DCBE is very effective to diagnose carcinoma and polyps greater than or equal to 1 cm, the most frequent causes of bleeding, but less effective to diagnose IBD and other nonfrequent causes. If a high-quality DCBE does not reveal the cause of bleeding, the contribution of a following colonoscopy will be to diagnose causes of bleeding other than carcinoma and polyps less than 1 cm and to offer therapeutic possibilities.

In four patients, ulcerative disease of the colon developed while they were taking nonsteroidal anti-inflammatory drugs (NSAIDs). Clinical presentation and laboratory and colonoscopic findings were similar to those of inflammatory bowel disease. Review of the literature disclosed 74 additional cases of NSAID-induced colitis in adults. This is a rare but serious, sometimes fatal, complication of NSAID therapy. The elderly and those taking long-term NSAID therapy appear to be at highest risk. The pathogenesis is thought to be related to inhibition of intestinal prostaglandin synthesis. Whether some NSAIDs are more likely to induce colitis than others is not known. Since NSAIDs are so widely prescribed and some are available without a prescription, heightened awareness by physicians and the lay public will be important in reducing injury from this disease, both by prevention and earlier recognition.

Arachidonic acid metabolites formed by both the cyclooxygenase and lipoxygenase pathways may contribute to the clinical diarrhea and colitis of inflammatory bowel disease. Patients with active ulcerative colitis have increased levels of leukotriene B4 in their rectal mucosa, and these levels tend to correlate with severity of the disease. In this study, we evaluated the efficacy of ingestion of fish oil n-3-omega-fatty acids, inhibitors of leukotriene synthesis, in the treatment of ulcerative colitis. Eleven patients with ulcerative colitis of mild to moderate severity were studied in a 8-month, double-blind, placebo-controlled, crossover trial of dietary supplementation with fish oil, which provided about 4.2 g of omega-3- fatty acids per day. A disease activity index based on patient symptoms and sigmoidoscopic appearance was used to assess efficacy. Mucosal leukotriene B4 production was measured by radioimmunoassay. Mean disease activity index declined 56% for patients receiving fish oil and 4% for patients on placebo (p less than 0.05). There were no statistically significant differences in histopathologic scores or colonic mucosal leukotriene B4 levels. All patients tolerated fish oil ingestion and showed no alteration in routine blood studies. No patient worsened; anti-inflammatory drugs could be reduced or eliminated in eight patients (72%) while receiving fish oil. We conclude that fish oil dietary supplementation results in clinical improvement of active mild to moderate ulcerative colitis but is not associated with significant reduction in mucosal leukotriene B4 production, compared with placebo therapy. Further studies are needed to elucidate the mechanism of action and optimal dose and duration of fish oil supplementation in ulcerative colitis.

Quality of life with inflammatory bowel disease has not been well examined. Recently, a questionnaire to determine subjective health status for patients with inflammatory bowel disease has been developed and verified. To examine the quality of life in a group of "well" outpatients with inflammatory bowel disease, we developed a self-administered form of this questionnaire containing 36 questions identifiable to five dimensions: systemic symptoms, bowel symptoms, functional impairment, social impairment, and emotional function. We identified outpatients with inflammatory bowel disease through the local chapter of the Ileitis and Colitis Foundation and distributed 396 questionnaires, by mail, with 182 being returned completed (46% response rate). Forty-eight age- and sex-matched controls filled out and returned an identical questionnaire. Response options for each question were framed on a seven-point scale in which 7 represented best function and 1 represented worst function. Male-to-female ratio and mean age were similar to those of controls for the inflammatory bowel disease group. In each dimension, as well as globally, the quality of life of patients with inflammatory bowel disease was significantly worse than that for their age- and sex-matched controls. In conclusion, this survey demonstrates that inflammatory bowel disease adversely affects quality of life in a highly motivated group of "well" outpatients when compared to an age- and sex-matched population.

This report reviews the clinical presentation, endoscopic, radiologic, and pathologic features, and response to therapy in eight patients more than 60 yr old who presented with segmental chronic active colitis associated with sigmoid diverticula. The finding of colitis limited to the sigmoid colon in an area of multiple diverticula with no associated features of Crohn's disease, the age at onset, the response to therapy, and the benign course all suggest a distinctive form of inflammatory bowel disease in these patients.

Pronounced changes in gut neuropeptide content have been observed in colonic tissues from animals with acute experimental colitis and in some patients with inflammatory bowel disease. The early decrease of CGRP in the colon during colitis in the animal studies suggest that CGRP is released during the inflammatory process. No data are available showing the biological action of released CGRP during inflammation. The sensory neurotoxin capsaicin was used in animal studies to examine the effect of sensory nerves on inflammation and healing in experimental animal models. The severity of colitis was enhanced after capsaicin pretreatment in acute and chronic animal models of colitis. These data support the hypothesis that sensory nerves exert a protective and healing-promoting function in the gut. CGRP is a good candidate for this action of sensory nerves because it is a major component in sensory nerve fibers. How CGRP exerts its protective function in the intestine is unknown. Data from gastric ulcer models support the hypothesis that a main action of CGRP is regulation of mesenteric and mucosal blood flow resulting in enhanced protection and tissue healing. Other effector roles of CGRP afferent nerve endings could also be considered.

We used rosters of the Crohn's and Colitis Foundation of America to identify potential cases and peer-nominated controls to explore the reported association between oral contraceptives and inflammatory bowel disease. Overall, women who used oral contraceptives were at increased risk of developing Crohn's disease (odds ratio = 1.49, 95% confidence interval (CI) = 0.99-2.26). The findings persisted after adjustment for age at symptom onset, decade of onset, education, marital status, and location of disease. There was an interaction with cigarette smoking; the risk associated with oral contraceptives was elevated in current smokers (odds ratio = 2.64, 95% CI = 1.22-5.75), but not in former smokers or never-smokers. The risk was not elevated for ulcerative colitis (odds ratio = 1.10, 95% CI = 0.65-1.85).

Subtotal colectomy with preservation of the rectum is now the procedure of choice for patients with severe colitis requiring emergency surgery. The use of subcutaneous 'rectal closure' when the retained distal bowel is placed at the caudal end of the abdominal incision in the subcutaneous or fascial layer is studied. An anal catheter may be placed to drain the rectum. Thirty-two patients (14 men, 18 women) of mean age 33 (range 17-77) years with severe inflammatory bowel disease (29 ulcerative colitis, one Crohn's disease, one indeterminate colitis, one Campylobacter colitis) underwent emergency colectomy with subcutaneous rectal stump closure. Twenty-three stumps were closed with staples, four sutured and five by both staples and sutures. Complications developed in seven patients (22 per cent), of which two required surgical intervention. One significant wound infection was treated successfully with a course of antibiotics. Three minor wound infections did not require specific treatment. The rectal stump was always readily located at the time of restorative surgery. This technique is recommended as a simple and safe alternative to an open mucus fistula provided that surgeons adhere to standard surgical principles; in particular the distal bowel should not be brought out into the wound under tension.

Products of arachidonic acid metabolism are elevated in patients with inflammatory bowel disease and this elevation is correlated with disease activity. Eicosapentaenoic acid competes with arachidonic acid and alters eicosanoid biosynthesis. In this experiment, the possibility that eicosapentaenoic acid could be used in the treatment of inflammatory bowel disease was investigated by determining the effect of 6 weeks of a fish oil-supplemented diet, enriched in eicosapentaenoic acid, on colonic and ileal morphology, histology, and in vivo fluid absorption in rats with 4% acetic acid-induced colitis. The results of an eicosapentaenoic acid-enriched diet were compared with results of saturated and polyunsaturated fatty acid-enriched diets. In rats with misoprostol pretreated acetic acid-induced colitis, an eicosapentaenoic acid-enriched diet reversed net colonic fluid secretion to absorption and prevented macroscopic and histologic injury, compared with saturated and poly-unsaturated fatty acid-enriched diets, which did not. The fish oil mucosal protective effect occurred in the presence of a 30-fold enhancement of PGE2 synthesis. In rats with non-misoprostol pretreated acetic acid-induced colitis, an eicosapentaenoic acid-enriched diet returned ileal fluid absorption to control levels, as compared with saturated and polyunsaturated fatty acid-enriched diets, which did not. In conclusion, a fish oil (eicosapentaenoic acid)-enriched diet, but not a saturated- or a polyunsaturated-enriched diet, protected colonic and ileal net fluid absorption in an experimental model of inflammatory bowel disease.

Cytomegalovirus (CMV) colitis is uncommon in patients who are not gravely immunodepressed. We report a case of fatal CMV colitis in a 54-year-old woman on low dose steroid therapy. She was admitted to hospital after sudden onset of abdominal pain and hemorrhagic watery diarrhea. After 25 days in the hospital, treatment with high dosage of methylprednisolone was started for presumed ulcerative colitis. Her condition worsened and she died 52 days after admission. It is important to recognize CMV colitis as differential diagnosis to inflammatory bowel disease, particularly when the colitis is refractory to immunosuppressive treatment.
