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.

Liver and biliary abnormalities are well-known complications of inflammatory bowel disease (IBD). It has been suggested that using total parenteral nutrition (TPN) may further impair liver function in these patients; this seems not to be so with total enteral nutrition (TEN). However, prospective trials comparing the incidence of liver function test (LFT) abnormalities with either TPN or TEN have not been carried out. Twenty-nine IBD inpatients with normal LFT, randomized to receive either TEN with a polymeric diet or isocaloric, isonitrogenous "all-in-one" TPN because of protein-energy malnutrition and/or severe disease, were included in the study. Sixteen patients (five with ulcerative colitis and 11 with Crohn's disease) received TEN, and 13 patients (eight ulcerative colitis and five Crohn's disease) were on TPN. All patients were on systemic steroids, and nine of them were on oral metronidazole. Both groups were homogeneous regarding age, sex, diagnosis, disease activity, nutritional status, daily nutrient supply, and days on artificial nutrition. Serum albumin levels significantly increased with TEN (32 +/- 1 to 38.2 +/- 1.6 g/liter, p less than 0.01), but not with TPN (32.1 +/- 2.2 to 33.9 +/- 1.4 g/liter, NS). Clinical improvement occurred in both groups of patients as shown by the change in the disease activity indexes. In all cases, measurements of serum alkaline phosphatase, serum bilirubin, aspartate aminotransferase, alanine aminotransferase, and gamma-glutamyltransferase were performed weekly. There were no significant differences in the initial LFT between both groups.(ABSTRACT TRUNCATED AT 250 WORDS)

To determine whether an elemental diet or prednisolone would be more effective for treating acute Crohn's disease, a controlled trial was conducted on 20 patients with acute Crohn's disease who had never received specific treatment. The first ten patients were put on an elemental diet and the remaining ten were prescribed prednisolone for six weeks at an initial dose of 0.7 mg/kg/day. Patients were assessed using the simple activity index, body weight, erythrocyte sedimentation rate, C-reactive protein and alpha 2 globulin, serum albumin, and radiographic findings of bowel lesions. At six weeks, the patients on the elemental diet showed a significantly greater improvement in the activity index, inflammatory signs such as C-reactive protein and alpha 2 globulin, and radiographic findings of bowel lesions than did those on the steroid. Patients who were given steroids for six weeks and then treated with the elemental diet for four weeks showed improvement in the radiographic findings of bowel lesions and inflammation. The present study strongly suggests that elemental diet is superior to steroids for treating active Crohn's disease.

The data from 238 patients (108 men, 130 women, mean age 29 [15-71] years), who had undergone operations for Crohn's disease between 1968 and 1988, were analysed retrospectively with the purpose of ascertaining the significance of an endoscopically demonstrated "early recurrence". In 170 patients postoperative colonoscopy had been performed at least once. In 130 patients the activity of the disease in the years before and after operation was compared in terms of such parameters as haemoglobin, erythrocyte sedimentation rate, serum albumin, body weight and the frequency of acute flare-ups of the disease and admissions to hospital. The probability of an endoscopically demonstrable recurrence was 90% after 5 years, while the corresponding figure for a symptomatic recurrence was 40%. This indicates that the routine performance of postoperative colonoscopies is of no value in assessing the prognosis. The probability of a reoperation was 21% after 5 years; in cases where both the ileum and colon were involved the probability was three times as high as in those with isolated involvement of either the small or the large intestine. Post-operatively, a substantial reduction in disease activity of several years' duration was achieved in the overall majority of cases.

Serum samples from 20 Indian children with diarrhoea were compared with those from 20 children resident in the United Kingdom who had been diagnosed as having ulcerative colitis, or Crohn's disease, or indeterminate colitis using enzyme linked immunosorbent assays specific for Entamoeba histolytica and Giardia lamblia. More than 50% of the United Kingdom patients had high IgG responses in ELISAs for E histolytica and G lamblia. A confirmatory ELISA showed that the British sera reacted specifically to bovine serum proteins rather than to protozoal antigens. Prior incubation of sera with 5% bovine serum prohibited this reaction. Bovine serum is an integral part of the crude soluble antigen used in most ELISAs for E histolytica and G lamblia and needs to be replaced with purified antigen preparations. The British sera also reacted to other commonly used blocking agents such as bovine serum albumin, casein, and normal sheep serum. These reactions were attributed to uptake of dietary antigens or an enhanced immunological response to these antigens in patients with inflammatory bowel disease.

Recurrence of Crohn's disease at the ileocolonic anastomosis after curative surgery is frequent. Prognostic value of several parameters at the time of surgery was studied in 37 patients to detect early symptomatic recurrence of Crohn's disease after surgery. These included patient age at the time of surgery, sex, disease duration before surgery, clinical activity index, length of resected bowel, presence of granulomas in resected bowel segment, indication for surgery, type of medical treatment before surgery, and biochemical parameters at the time of surgery (ESR, C reactive protein and serum albumin level). Symptomatic recurrence associated with endoscopic lesions at the anastomotic site was observed in 10 of 37 patients (27 percent), within one year after surgery. None of the studied parameters were able to differentiate the patients with recurrence or not.

The records of 102 patients operated on by one of the authors for Crohn's disease during the past 15 years were reviewed. Twenty-seven patients with confined (abscess present) or free perforation were evaluated. The average age was 31 years and the mean duration of disease was four years. Only two of the 27 patients had had previous surgery. All patients presented with a combination of pain, weight loss, and diarrhea. Twenty-three patients were afebrile, 17 had abdominal tenderness, and 6 had an abdominal mass. The average serum albumin was 3.7, the average hematocrit was 35 per cent and the average WBC was 13,000. Radiologic tests were abnormal in 23 of the 27 patients. All patients had been on medical treatment for Crohn's disease, and 19 of 27 were on high-dose steroids at the time of surgery. Ten of the 27 had a bowel prep before surgery and all had preoperative and postoperative antibiotics. All patients were surgically managed by resection and primary anastomosis without proximal diversion or delayed reconstruction. Drains were used in one third of the patients. Intraoperative cultures revealed gram-negative rods with Escherichia coli, enterococcus, and Enterobacter the most common. One enterocutaneous fistula, two superficial wound infections, and one death were recorded. Based on these results, the authors believe that an aggressive one-stage surgical approach for these complicated problems can be recommended. The low morbidity and mortality justifies this approach that results in considerable improvement in lost work time, length of hospital stay, number of readmissions, and significant cost control.

The proportion of oligosaccharide chains on the Fc fragment of IgG which terminate with N-acetylglucosamine (GlcNAc) rather than galactose is increased in rheumatoid arthritis and tuberculosis, and in sera from patients with Crohn's disease, probably because of decreased activity of a galactosyltransferase in B lymphocytes. We have assayed the prevalence of agalactosyl oligosaccharides on IgG in sera from 67 patients with inflammatory bowel disease (32 ulcerative colitis and 35 Crohn's disease). The prevalence of agalactosyl IgG significantly increases in the majority of Crohn's patients (19/35 patients), and correlates with the level of C-reactive protein (r = 0.79), and inversely with the concentration of serum albumin. Sera from ulcerative colitis patients show less frequent (nine of 32) and less marked rises in agalactosyl IgG, and sera with high C-reactive protein values can contain normal levels. Thus in ulcerative colitis no correlation was seen between the two assays. The diseases in which the percentage of agalactosyl IgG is raised (rheumatoid arthritis, tuberculosis, Crohn's disease and some ulcerative colitis) are characterised by simultaneous T cell mediated granulomatous tissue damage, and acute phase responses. Levels are normal in less tissue damaging granulomatous conditions, including sarcoidosis, and leprosy (except during episodes of erythema nodosum leprosum). We suggest therefore that a raised percentage of agalactosyl IgG is a correlate of a particular type of T cell mediated pathology which may be relevant to the pathogenesis of inflammatory bowel disease.

Fifty-eight patients with Crohn's disease were studied in order to compare disease activity as measured by a clinical scoring system, with nutritional status, the laboratory measurements reflecting nutritional status, and the serum levels of acute phase proteins, using principal component analysis and stepwise multiple regression analysis. We confirmed that orosomucoid is the laboratory measurement which correlates best with clinical assessment of disease activity, followed by ESR and C-reactive protein. Serum albumin correlated poorly with clinical disease activity, although body weight showed an inverse correlation. Serum fibronectin, a protein involved in the production of fibrous tissue, did not detect the presence of fibrous strictures in the intestine.

The status of water- and fat-soluble vitamins was prospectively evaluated in 23 patients (13 men, 10 women, mean age 33 +/- 3 yr) admitted to the hospital with acute or subacute attacks of inflammatory bowel disease. Protein-energy status was also assessed by means of simultaneous measurement of triceps skinfold thickness, mid-arm muscle circumference, and serum albumin. Fifteen patients (group A) had extensive acute colitis (ulcerative or Crohn's colitis), and eight cases (group B) had small bowel or ileocecal Crohn's disease. Eighty-nine healthy subjects (36 men, 53 women, mean age 34 +/- 2 yr) acted as controls. In both groups of patients, the levels of biotin, folate, beta-carotene, and vitamins A, C, and B1 were significantly lower than in controls (p less than 0.01). Plasma levels of vitamin B12 were decreased only in group B (p less than 0.01), whereas riboflavin was lower in group A (p less than 0.01). The percentage of patients at risk of developing hypovitaminosis was 40% or higher for vitamin A, beta-carotene, folate, biotin, vitamin C, and thiamin in both groups of patients. Although some subjects had extremely low vitamin values, in no case were clinical symptoms of vitamin deficiency observed. Only a weak correlation was found between protein-energy nutritional parameters and vitamin values, probably due to the small size of the sample studied. The pathophysiological and clinical implications of the suboptimal vitamin status observed in acute inflammatory bowel disease are unknown. Further studies on long-term vitamin status and clinical outcome in these patients are necessary.
