The short and long-term effects of postoperative total parenteral nutrition (TPN) on body composition were studied in a randomised series of patients undergoing major colorectal surgery. Ninety-two patients (colorectal cancer: 50, ulcerative colitis or Crohn's disease: 42) were grouped according to diagnosis and clinical inflammatory activity. TPN was given for 9.7 +/- 1.1 days. The complication rate was not changed by the TPN. Nitrogen balance was studied during the first week. Body weight, total body potassium, triceps skinfold, serum albumin and body water were measured before and at intervals up to 24 weeks after the operation. Cumulative nitrogen balance in control patients at 7 days after surgery was -47.3 g. Patients given TPN balanced nitrogen intake and output (cancer patients and patients with quiescent inflammatory bowel disease, IBD) or were in positive balance (patients with active IBD). Weight loss at 1 week after surgery was less in TPN patients compared to controls and this difference remained statistically significant up to 6 months after termination of the nutritional treatment. A similar, although not statistically significant, difference was noted in total body potassium and triceps skinfold. Patients with active IBD regained pre-operative body composition earlier than cancer patients and patients with quiescent IBD. It is concluded that TPN after major colorectal surgery reduces postoperative weight loss and that this effect lasts after termination of the nutritional treatment. In the absence of increased body potassium and increased body water, we conclude that the long-term effect of TPN on body weight is most likely due to preservation of fat.(ABSTRACT TRUNCATED AT 250 WORDS)

After diluting faecal samples with a solution of Brij and saline and subsequently ultrafiltrating the faecal mixtures, lysozyme concentration can be reproducibly measured in the obtained faecal fluids, using a turbidimetric method. Measuring faecal lysozyme concentration enables discrimination normal individuals and patients with irritable bowel syndrome between patients with inflammatory bowel disease and colonic cancer. Lysozyme distribution in stools appears to be homogeneous. Faecal lysozyme concentration is stable when samples are stored during at least 1 wk at 6 degrees C. It appears that the lysozyme activity is directly correlated with the clinical status and severity of the disease. Faecal lysozyme may thus serve as an important tool both in diagnosis and in follow-up in the out-patients clinic for gastroenterology.

The serum concentrations of serum amyloid A protein (SAA), C-reactive protein (CRP), alpha 1-antichymotrypsin (alpha 1-ACT) and alpha 1-acid glycoprotein (alpha 1-AGP) have been measured in eighty-six patients with Crohn's disease, twenty-five patients with ulcerative colitis and twenty-two patients with the irritable bowel syndrome. In the Crohn's and ulcerative colitis group significant increases in concentration were observed in all four proteins, which parallelled disease severity as defined by other conventional laboratory parameters formulated into a simple activity index. In the irritable bowel group no significant changes were seen. Serum amyloid A and CRP concentrations were significantly lower in ulcerative colitis than in Crohn's disease when mild, but did not differ significantly when severe. Serum amyloid A correlated well with CRP (r = 0.83) and alpha 1-ACT (r = 0.80), but less well with alpha 1-AGP (r = 0.65). Serum amyloid A was the most sensitive protein (77%) but had the lowest specificity (74%). C-reactive protein was less sensitive (58%) than SAA but had greater specificity (100%). Alpha 1-ACT had a sensitivity and specificity similar to CRP and, therefore, provided little or no additional information. Alpha 1-AGP, although also 100% specific, had the lowest sensitivity (34%) and, therefore, is probably the least useful acute phase monitor of inflammatory bowel disease. The role, and associated problems, of SAA measurements are discussed.

Gamma interferon (IFN-gamma) production by peripheral blood mononuclear cells (PBM) was measured in 21 patients with Crohn's disease, in 15 patients with ulcerative colitis, in 12 patients with non-IBD gastrointestinal disease (disease control), and in 28 healthy controls. T-cell subset proportions and serum levels of thymosin alpha 1 and thymosin beta 4, two hormonelike thymic peptides, were also determined. No differences were seen in T-cell subset proportions in patients with Crohn's disease or ulcerative colitis when compared to healthy controls or to the disease-control group. In vitro IFN-gamma production was markedly decreased in Crohn's disease and in untreated, but not treated, patients with ulcerative colitis. Preincubation of PBM prior to the addition of inducer mitogen resulted in enhanced IFN-gamma production in patients with Crohn's disease or ulcerative colitis which significantly exceeded that seen either in healthy controls or in the disease-control group. Serum thymosin alpha 1 levels were comparable in all study groups; however, serum thymosin beta 4 concentrations were significantly higher in all patient groups than in the healthy controls. These results confirm a defective in vitro IFN-gamma production in patients with IBD which is apparently independent of endocrine thymus regulation.

Colonic epithelial cells (CEC) were isolated from actively inflamed mucosa of IBD patients and checked for HLA-DR, HLA-DP, and HLA-DQ. Half of the freshly isolated CEC from IBD tissue expressed DR, and one third were positive for DP and DQ. Normal human CEC were then cultured for 24 h and their expression of these markers in response to different types of in vitro stimulation was investigated. A significant increase in the expression of DR, DP and DQ was observed in response to the nonspecific mitogen phytohaemagglutinin (PHA), the lymphokine gamma-interferon (gamma-IFN) and the epidermal growth factor (EGF). The enhancement of DR expression was more marked than that of DP and DQ. The effect of gamma-IFN was more rapid and significantly more marked than that of either PHA and EGF for all three antigens. EGF appeared to be more potent than PHA in enhancing the expression of DP and DQ. The data from this study indicate that HLA-D region antigens can be induced on human CEC by different types of stimuli and provide further evidence that the expression of these markers in the colonic epithelium is a normal event the magnitude of which can increase under various circumstances. The data also suggest that the increased expression of HLA-D region antigens by IBD CEC occurs as a result of different mechanisms, and that this expression is an indicator of the active participation of the colonic epithelium to the mucosal inflammatory response.

The sample population in this initial case control study of the adenosine diphosphate ribosyl transferase (ADPRT) response of inflammatory bowel disease patients included: 23 patients with ulcerative colitis (UC)-active and inactive, 13 patients with Crohn's disease (CD)-active and inactive, 14 first degree relatives of UC and CD patients, and 19 age-matched controls. Adenosine diphosphate ribosyl transferase activity was determined after one hour incubation with 1% plasma (the constitutive value) or with 1% plasma and 100 microM H2O2 (the activated value) with the resulting difference designated as the induced value. Statistically significant decrease in ADPRT activity was found for the constitutive, activated and induced values in human mononuclear leucocytes of UC and CD patients, compared with controls. The values in the first degree relatives of UC and CD patients were not significantly different from either the control or disease populations, indicating an intermediate ADPRT response. These results may be related to the nature of the immunological response of IBD patients and comparable with similar findings in other diseases with known DNA repair deficiencies--for example, colon cancer.

This presentation describes the progress during 1982-1986 of the OMGE Multinational Survey of patients with inflammatory bowel disease. After a brief description of the study design and protocol, the status of the survey in 1986 is presented. In all, 40 centres contributed 3175 cases at that time, data collection being meticulous via previously designed proformata. Diagnostic criteria are next discussed. Little change between 1976 and 1986 is noted, with wide congruence of diagnostic thought, now codified into a simple (and recommended) OMGE diagnostic scoring system. Patients seen prior to 1978 were reviewed in 1986. Where attempted, a follow-up of over 86% was achieved, usually more than 4 years after the original presentation involving no less than 5215 'patient-years' of observed follow-up. Following these overall considerations, details of four subprojects are annexed, each of which was presented as a 'free paper' at the 8th World Congress and concerning, respectively, the changing natural history of IBD, risks of perforation and toxic megacolon in the 1980s, IBD in elderly patients, and features associated with recurrence in Crohn's disease.

Previous work on the inheritance of disease has often used certain measures of HLA haplotype concordance (such as the number of haplotypes "identical by descent," IBD) among affected siblings from each of a number of sibships, each of which contains at least two affected siblings. Here we introduce a new measure of HLA haplotype discordance between the affected and unaffected siblings of each sibship (provided there is at least one of each). We show how the measure can be used to give a simple test for inheritance, which we exemplify with data.

Inflammatory Bowel Disease is characterized by two major entities, Crohn's Disease and Ulcerative Colitis. These bowel diseases have associated problems involving the eyes, joints, skin, kidneys, immunological system, hepatobiliary system, and psychiatric disturbances. A regional IBD registry encompassing 18 hospitals and IBD specialists in east/northeast Pennsylvania was established to promote awareness of the clinical and epidemiological aspects of the disease. Results of this data collection effort will be shared with patients and physicians through the use of newsletters and symposia. A Basic History (HX) form, an Operative Data (OR) form, and an Annual Follow-up (FU) form was used to collect relevant data. Participation is voluntary and all information is confidential.

Fifty male patients with proctitis were examined and the clinical, microbiological, serological and proctological features compared with 51 known male homosexuals attending the genitourinary (GU) clinic at the same hospital. The homosexuals had a short history of bowel symptoms, minor sigmoidoscopic and histological changes on rectal biopsy and many positive serological markers of sexually transmitted infection. There was some evidence of sexually transmitted disease in the IBD patients and three were homosexuals. IgG antibodies were positive for chlamydia trachomatis (n = 10) and hepatitis A (n = 7). One had a positive screening test for syphilis. Stool examination and rectal swab cultures were positive in two patients for cryptosporidium and cytomegalovirus respectively. Gastroenterologists must be aware of the possibility of specific infection in IBD patients and a clinical history should include sexual preferences and practices. If homosexuality is admitted, specific infection must be sought and excluded.
