Abstract: BACKGROUND & AIMS: N-3 fatty acids from fish oil, antioxidants, and short-chain fatty acids (SCFAs) produced during the fermentation of soluble fiber may attenuate inflammation associated with ulcerative colitis (UC). We assessed the efficacy of a nutritionally balanced oral supplement enriched with fish oil, fructooligosaccharides, gum arabic, vitamin E, vitamin C, and selenium on disease activity and medication use in adults with mild to moderate UC. METHODS: A total of 121 patients with UC and a disease activity index (DAI) from 3-9 on a 12-point scale were block randomized for extent of disease and smoking status. In addition to their usual diet, patients consumed 18 oz of the oral supplement or a carbohydrate-based placebo formula each day for 6 months. Clinical and histologic responses were assessed at 3 and 6 months or at the final visit. A change in average prednisone use between groups was tested by using a linear mixed-effects model. RESULTS: Eighty-six patients completed the study. Baseline characteristics were not different between groups except for a higher total DAI score in the oral supplement group (7.3 +/- 1.3; n = 36) compared with the placebo group (6.2 +/- 2.0; n = 50) ( P < .05). Both groups showed significant and similar degree of improvement at 6 months in DAI (-2.5 for oral supplement and -2.8 for placebo) and histologic index (-1.9 for oral supplement vs. -2.0 for placebo). Both intent-to-treat and completed patients given oral supplement had a significantly greater rate of decrease in the dose of prednisone required to control clinical symptoms over 6 months as compared with the placebo group ( P < .001). CONCLUSIONS: The improvement in clinical response combined with a decreased requirement for corticosteroids suggest that this enriched oral supplement can be a useful adjuvant therapy in patients with UC.

Abstract: Telepathology (TP) is the practice of remote diagnostic consultation of electronically transmitted, static, digitalized images. The diagnostic efficacy of TP-based consultation services has not been widely tested. Dysplasia that arises in association with chronic ulcerative colitis (CUC) is, at present, the most important marker of an increased risk of malignancy in patients with this disease. Unfortunately, dysplasia is difficult to diagnose histologically and, as a result, suffers from a significant degree of intra- and interobserver variability. Furthermore, it is often necessary to obtain expert consultation of potential CUC-associated dysplasia cases before treatment. Therefore, the aim of this study was to evaluate the utility and interobserver variability of diagnosing dysplasia in CUC with the use of TP. Static, electronically transmitted, digitalized images of 38 CUC cases with areas considered negative, indefinite, or positive for dysplasia (low or high grade) were evaluated independently by four gastrointestinal pathologists. All cases were then graded by each of the pathologists by light-microscopic examination of the hematoxylin and eosin-stained glass slides. The degree of interobserver variability was determined by kappa statistics. Overall, there was a fair degree of agreement (kappa = 0.4) among the four reviewing pathologists after analysis of the digitalized images. The poorest level of agreement was in the indefinite and low-grade dysplasia categories. Grouping together several diagnostic categories (for instance, indefinite and low-grade dysplasia, or low-grade dysplasia and high-grade dysplasia) had no effect on the overall level of agreement. The degree of variability in interpretation of glass slides was slightly better (kappa = 0.43) but still remained fair. After reviewing all cases by glass slide analysis, the diagnosis was changed in 38% of the slides; in the majority of these, the grade of dysplasia was increased. Use of TP for consultation in CUC-associated dysplasia has a moderate level of interobserver agreement. Because of a variety of technical reasons, diagnoses rendered by evaluation of digitalized images tended to be of a lower grade than that observed after a review of the glass slides.

Abstract: PURPOSE: Preservation of the anal transitional zone during ileal pouch-anal anastomosis is still controversial because of the risk of dysplasia and the theoretical risk of associated cancer. Without long-term follow-up data, the natural history and optimal treatment of anal transitional zone dysplasia are unknown. The aim of this study was to determine the long-term risk of dysplasia in the anal transitional zone and to evaluate the outcome of a conservative management policy for anal transitional zone dysplasia. METHODS: Two hundred ten patients undergoing anal transitional zone-sparing ileal pouch-anal anastomosis for ulcerative or indeterminate colitis between 1987 and 1992 and who were studied with serial anal transitional zone biopsies for at least five years postoperatively were included. Median follow up was 77 (range, 60-124) months. RESULTS: Anal transitional zone dysplasia developed in seven patients 4 to 51 (median, 11) months postoperatively. There was no association with gender, age, preoperative disease duration or extent of colitis, but the risk of anal transitional zone dysplasia was significantly increased in patients with prior cancer or dysplasia in the colon or rectum. Dysplasia was high grade in one and low grade in six. Two patients each with low-grade dysplasia detected on three separate occasions underwent mucosectomy 29 and 38 months after detection of low-grade dysplasia, but no cancer was found. The five other patients with dysplasia on one or two occasions were treated expectantly and were apparently dysplasia-free for a median of 72 (range, 48-100) months. CONCLUSIONS: Anal transitional zone dysplasia after ileal pouch-anal anastomosis is infrequent, is most common in the first two to three years postoperatively and may apparently disappear on repeated biopsy. Anal transitional zone preservation did not lead to the development of cancer in the anal transitional zone after five to ten years of follow-up. Long-term surveillance is recommended to monitor dysplasia. If repeat biopsy confirms persistent dysplasia, anal transitional zone excision with neoileal pouch-anal anastomosis is recommended.
