Serum levels of zinc, copper, and selenium, and alkaline phosphatase activity were prospectively studied in 29 patients with inflammatory bowel disease. Fifteen patients had extensive active colitis (active colitis group). Seven patients had active, and seven cases inactive small bowel or ileocecal Crohn's disease (small bowel disease group). Ninety-three healthy subjects acted as controls. Serum trace element levels were considered in relation to vitamin A and E levels, nutritional parameters, the activity of the disease, and the recent intake of steroids. The effect of total enteral nutrition on serum trace elements was studied in seven cases. Serum zinc levels were lower and serum copper levels higher in the active colitis group than in controls (p = 0.0007, and p = 0.02, respectively). More than 50% of patients with active colonic or small bowel disease showed zinc levels below the 15th percentile of the control group. Serum zinc levels correlated with plasma vitamin A in acute colitis (r = 0.67; p = 0.006), and with both serum albumin concentration (r = 0.76; p = 0.002) and disease activity score (r = -0.67, p = 0.009) in patients with small bowel disease. The copper:zinc ratio was higher in the active colitis group than in controls (p = 0.002). In spite of the increase in serum albumin levels and the decrease in disease activity, serum zinc levels remained low after total enteral nutrition. The implications of the abnormal trace element status in patients with inflammatory bowel disease are discussed.

Activated T cells can be visualized in the intestinal lamina propria in a number of gastrointestinal diseases including food-sensitive enteropathy (coeliac disease), inflammatory bowel disease and intractable diarrhoea of infancy. Experimental studies have shown that T-cell activation in human intestinal lamina propria in vitro produces an increase in crypt cell proliferation, villous atrophy, increased HLA-DR expression on enterocytes, increased intra-epithelial lymphocyte numbers, and phenotypically, macrophage activation. All of these features are seen in human gastrointestinal disorders and it is proposed that T-cell activation to wheat (in coeliac disease), milk (cows' milk-sensitive enteropathy), and unidentified luminal antigens (Crohn's disease) plays a primary role in the pathogenesis of these disorders.

During a 12-year period, 46 children and adolescents with inflammatory bowel disease were followed from the time of diagnosis with regular biochemical tests of liver function. Thirty-four patients had ulcerative colitis and 12 had Crohn's disease. Mean age at the time of diagnosis was 10.2 years (range 7 months-17 years) and the mean follow-up period was 5.2 years (range 1-11 years). Pathological liver function tests were found in 60% of the 34 patients with ulcerative colitis: 9 of these 20 patients demonstrated more severe disturbance, usually at the time of diagnosis. Liver damage was most frequent in patients with total colitis. Liver biopsy was performed in eight patients, demonstrating "pericholangitis", fibrosis and in one case cirrhosis. Morphometry of electron microscopical pictures revealed a significantly increased number of lysosomes and dilated cisternae of the rough endoplasmic reticulum. ERCP was performed in two patients, verifying primary sclerosing cholangitis in one. Four of the 12 patients with Crohn's disease had mildly pathological liver function tests. No correlation was found to the extent, duration or treatment of bowel disease. In our series of juvenile inflammatory bowel disease, liver damage occurred frequently, especially in ulcerative colitis. The more severe changes tended to coincide with the onset of bowel disease.

To test our hypothesis that the erythrocytic sedimentation rate (ESR) correlates well with clinical activity in inflammatory disease of the colon, but not of the small bowel, we stratified 49 Crohn's disease patients according to their anatomic involvement and then measured the correlations between ESR and clinical activity within each of these anatomical subgroups. For 18 patients with Crohn's disease involving primarily the colon, there was a trend toward a direct correlation between clinical score and ESR (p = 0.15). In the 14 patients with Crohn's disease limited to the colon, this direct correlation was even more pronounced and statistically significant (p less than 0.02). By contrast, an opposite trend was observed for patients with small bowel disease. For the 26 patients with disease involving predominantly the small bowel, as well as for the 22 with disease limited to small bowel, there were statistically significant inverse correlations between clinical score and ESR (p less than 0.04). This difference between the directions of the correlations for Crohn's colitis versus ileitis was statistically significant (p less than 0.05). This study provides further evidence for the importance of analyzing putative indications of disease activity separately for each of the protean forms in which Crohn's disease occurs.

Forty-two patients underwent a resection for acute or chronic complications of Crohn's disease during the years 1983-1987. The colon was involved in 38% (16 patients), the small bowel in 31% (13 patients) and the ileocaecal region in 31%. In small bowel disease, the indication for operation was either an intestinal obstruction or an internal abscess. In colonic locations, poor response to medical therapy was the indication for operation in 10 patients (63%), and an acute complication in the remaining cases. The operations performed were always "radical resections": 13 resections of small bowel, 13 ileocaecal resections, 7 ileocolectomies with ileosigmoidostomies, 6 ileocolectomies with ileorectostomies, 2 left side hemicolectomies with colorectostomies and one total coloproctectomy. There was no operative mortality. A post-operative complication occurred in two patients (4.8%). The recurrence rate was 12% after 30 months average follow up in the 34 patients with only one operation for Crohn's disease. There was no second recurrence in the 8 patients operated for a first recurrence. The factors affecting recurrence after resection were: a short pre-operative time interval since first clinical symptoms: 4.6 years versus 5.3 years without recurrence (p less than 0.01); the colonic location of the Crohn's disease (p less than 0.02). Colonic location rate of the disease was found to be higher in this study as compared to others. Since "radical resection" fails to cure all patients, surgery should be restricted to acute on chronic complications.

The records of 51 patients diagnosed with enterovesical fistulas at Virginia Mason Medical Center from 1974 to 1988 were reviewed. Diverticulitis (41%), Crohn's disease (17%), and colorectal cancer (16%) were the major causes. In 50 of 51 patients, the diagnosis was made on the basis of the clinical history and the urine culture. Radiologic and endoscopic studies failed to identify the fistula in 20%, though all were confirmed at operation or autopsy. In four of eight patients with fistulas secondary to colorectal cancer, malignancy was not diagnosed preoperatively. Operation was performed in 84% of the patients. One-stage resection of the bowel was performed in 66% of patients with the intent of removing the fistula. The complication rate was 8% with no deaths. All multi-stage procedures were performed for fistulas complicated by abscess or bowel obstruction. There were two postoperative deaths in patients with metastatic cancer undergoing palliative diversion. All eight patients treated by diverting colostomy had persistent fistulas and urinary sepsis. All eight patients treated with antibiotics but without operation were free of complications of the fistula until death from other causes. Enterovesical fistula is a clinical diagnosis. Preoperative studies should be used to delineate the bowel disease and search for malignancy rather than to see the fistula, which is clinically apparent. One-stage resection of the involved bowel is the procedure of choice in the absence of abscess or bowel obstruction. When resection is not feasible, medical management with antibiotics is preferable to colostomy.

The recognition of potentially noxious physiologic substances in the intestinal milieu prompted the use of an "elemental" semihydrolyzed formula diet in the prophylaxis of experimental acute ischemic enteropathy. Elemental diets have been used in the management of a variety of digestive diseases. An elemental diet protects the intestinal mucosa of rodents from radiation injury and facilitates mucosal healing. Clinical trials have shown the benefits of this form of treatment in the prevention of acute radiation enteropathy and in the therapy for delayed radiation enteropathy and Crohn's disease.

The Hermansky-Pudlak syndrome (HPS) is a triad of tyrosine-positive albinism, platelet dysfunction, and the deposition of an abnormal ceroid-like pigment in the tissues. Complications of the syndrome, such as pulmonary fibrosis, renal failure, and cardiomyopathy, have been described. Granulomatous colitis has been documented in several families with the HPS. The bowel disease of the HPS is a unique type of inflammatory bowel disease with clinical features suggestive of idiopathic ulcerative colitis and pathologic features suggestive of Crohn's disease. Analogous to the presentation of Crohn's disease with perianal and perirectal involvement, we describe the occurrence of perianal disease and a perirectal abscess in a 29-yr-old woman with HPS and mild granulomatous colitis.

The first known case involving an association of Sweet's syndrome with Crohn's disease is described. A 36-year-old woman developed a diarrhea, fever, and infiltrated erythematous cutaneous plaques on neck and limbs, consistent with a presumptive diagnosis of Sweet's syndrome. This was confirmed by a skin biopsy showing a dense dermal infiltrate of polymorphonuclear leukocytes. Crohn's disease, extending from the anus to the terminal ileum, was diagnosed as well. Prednisolone treatment resulted in the improvement of both the bowel disease and skin lesions.

The effect of a long acting somatostatin analogue SMS 201-995 on stomal effluents in patients with severe short bowel syndrome was investigated in a double blind placebo controlled balance study. Six patients, five with Crohn's disease and one with radiation enteropathy were studied. Five patients had a jejunostomy and one an ileostomy. The patients had a normal food intake, but because of severe malabsorption had received home parenteral nutrition for several years. Faecal mass was reduced (p less than 0.005) and intestinal net sodium absorption was increased (p less than 0.005) by intravenous infusion of SMS 25 micrograms/h. Net absorption of potassium, calcium, magnesium phosphate, zinc, nitrogen and fat was not influenced. Subcutaneous injections of 50 micrograms SMS every 12 hours had a similar effect on net intestinal absorption of sodium and water. Four patients continued with a five to six months open follow up study when subcutaneous SMS in the same dose was administered by the patients at home. The effect on faecal sodium loss persisted, but in one patient faecal mass gradually increased and finally exceeded pretreatment values. SMS may decrease net absorption of water and sodium following reduced secretion of digestive juices rather than by increasing absorptive capacity. SMS may be useful as an antidiarrhoeal drug in patients with high output jejuno- or ileostomies, but in patients who need permanent parenteral nutrition the effect is too small to significantly alter management.
