An oral pancreatic function test (PFT) using the synthetic peptide N-benzoyl-L-tyrosyl-p-aminobenzoic acid can assess pancreatic exocrine function, since urinary recovery of the ingested dose is an indirect index of chymotryptic activity. We have studied 34 subjects using this oral PFT, which correctly distinguished the control group (8 subjects) from the pancreatitis group (10 patients), results correlating well with Lundh test findings. However, the test was falsely abnormal on 9 out of 16 occasions in patients with bowel or liver disease. We therefore conclude that the present test cannot distinguish small-bowel disease from pancreatic disease, which is often the diagnostic problem, and is also frequently falsely abnormal in the presence of chronic liver disease.

The tetracycline class of antibiotics is infrequently used in clinical pediatrics due to its side effects: they include anorexia, nausea, vomiting and diarrhea. Hypersensitivity, a photosensibility reaction and a brownish discoloration of teeth is less frequently, a pseudotumor cerebri is rarely seen. Once therapeutic plasma levels are exceeded however, either by overdosage or decreased renal or hepatic clearance of the drug, serious complications like a secondary Fanconi-Syndrom or a nephrogenic diabetes insipidus can occur. The increased toxicity of tetracyclines in pregnant women is well known. We would like to report a fatal case, where serious complications like a secondary Fanconi-Syndrom, toxic degeneration of the liver, a clinically undected pancreatitis and a protein loosing enteropathy are though to be either direct consequences of tetracycline overdosage or the indirect effect of a shocklike syndrom by means of a nonoliguric renal failure induced by tetracycline.

Three cats were thin despite eating well. Steatorrhoea was confirmed in each by 72-hour fat assimilation tests. Fat digestibility in all 3 increased twofold when the diet was supplemented with pancreatic enzymes, suggesting the possibility of exocrine pancreatic insufficiency. However, examination of stained faecal smears gave evidence of both maldigestion and malabsorption of fat, without maldigestion of starch, and only one case had indications of protein maldigestion. In the latter cat, fat digestibility normalised with pancreatic enzyme supplementation and exocrine pancreatic insufficiency was considered likely. However, at post-mortem examination enteropathy and pancreatitis, but not exocrine pancreatic insufficiency, were found. The cause of fat malassimilation in these cats was unknown. The evaluation of malassimilation in cats is difficult because investigative tests used in other species are either unsuitable or have not been evaluated in cats.

Lifestyle and dietary patterns are in the process of rapid transformation in Soweto. Comparisons with whites indicate differences in bowel behaviour, lactase deficiency and breath methanes. The association between smoking pipe tobacco and cancer of the oesophagus is confirmed, but home-brew consumption has been found to be the major risk factor in this cancer. A recent swing to Western-type alcohol has led to the emergence of alcohol-induced pancreatitis in blacks. Urbanisation and westernisation have also affected the influence of the traditional healer and the incidence of duodenal ulcer disease. The fundamental environmental influence which determines non-infective large-bowel disease is diet. A dietary survey of Sowetans indicates that their present diet is low in fat and fibre. Despite the latter, appendicitis is still relatively uncommon. Other significant differences are observed in colorectal cancer and diverticular disease.

Plasma concentrations of peptide YY (PYY), a newly isolated peptide produced by ileal and colonic endocrine cells, were measured in several groups of patients with digestive disorders after a standardized normal breakfast. Peptide YY levels were found to be grossly elevated in patients with steatorrhea due to small intestinal mucosal atrophy (tropical sprue). Basal levels in these patients were 79 +/- 18 pM, which was nearly 10-fold higher than those seen in healthy controls (8.5 +/- 0.8 pM). Patients with steatorrhea due to chronic destructive pancreatitis also had substantially increased basal PYY levels (47.5 +/- 6.3 pM), and their postprandial response was also greater than that of normal subjects. Moderately elevated plasma PYY concentrations were seen in patients with inflammatory bowel disease and patients recovering from acute infective diarrhea. In contrast, patients with diverticular disease, duodenal ulcer, and functional bowel disease had normal PYY responses. These changes in the secretion of PYY responses. These changes in the secretion, may shed light on the physiologic role of this newly discovered peptide and on intestinal adaptation to common digestive disorders.

The test for pancreatic exocrine function using N-benzoyl-L-tyrosyl-p-aminobenzoic acid (BTP test) does not require duodenal intubation, but misleadingly abnormal results often occur in patients with liver or bowel disease because the p-aminobenzoic acid (PABA) released by chymotrypsin hydrolysis of the peptide either is not conjugated or is malabsorbed. This study evaluated a modified BTP test, using a tracer dose of 14C-PABA to eliminate misleading results, to assess exocrine function from a single six-hour collection of urine. The test clearly distinguished all patients with pancreatic steatorrhoea from normal subjects and identified patients with less severe pancreatitis as often as did the Lundh test. Furthermore, in patients with bowel or liver disease the misleadingly abnormal results of the unmodified BTP test were eliminated by the modified test in all but one case. These findings suggest that the modified BTP test provides a practical alternative to conventional tests of pancreatic function that entail duodenal intubation.

The nature of the gastrointestinal injury following bone marrow transplantation and its clinical and nutritional sequelae are poorly defined. Prospective assessments of gastrointestinal function, nutritional status, and wellbeing were therefore carried out in 47 consecutive patients (28 males, 19 females; mean age 8.4 years) undergoing bone marrow transplant. 31 diarrhoeal episodes (median duration 9.5 days) occurred in 27 patients at a median of 10 days after transplantation. Ninety one per cent of episodes were associated with protein losing enteropathy. Protein losing enteropathy was more severe in graft-versus-host disease (GVHD) comparing with other causes. It led to a substantial fall in serum albumin and there was a negative correlation between faecal alpha 1-antitrypsin concentrations and serum albumin. Transient pancreatic insufficiency developed in 18 patients, and pancreatitis in one. Intestinal permeability was normal in 12 patients who had no diarrhoea during the conditioning treatments. Diarrhoeal patients had a significantly greater decrease in nutritional status and wellbeing than patients without diarrhoea. Gastrointestinal injury following bone marrow transplantation is thus complex. Severe protein losing enteropathy in this context suggests the presence of GVHD.

A 2-month-old female Persian cat that had been showing episodes of anorexia and diarrhea for the previous 4 weeks was presented in shock and died 2 days later. Numerous Gram-positive cocci were located along the brush border of small intestinal villi, without significant inflammatory infiltration. Similar bacteria were present within hepatic bile ducts and pancreatic ducts and were associated with suppurative inflammation and exfoliation of epithelial cells. Culture of the liver and lung yielded bacteria identified as Enterococcus hirae. Fecal culture from an asymptomatic adult female from the same cattery also yielded large numbers of E. hirae. To our knowledge, this is the first report of E. hirae enteropathy in a cat and the first report of ascending cholangitis and ductal pancreatitis caused by an Enterococcus spp.

Misoprostol, a prostaglandin E1 analog, is a racemate of four stereoisomers. On administration it rapidly de-esterifies to its active form, misoprostolic acid. Misoprostolic acid is 85% albumin bound and has a half-life of approximately 30 minutes. It is excreted in urine as inactive metabolites. No significant drug interactions have been reported. Besides its gastrointestinal protective and uterotonic activities, misoprostol regulates various immunologic cascades. It inhibits platelet-activating factor and leukocyte adherence, and modulates adhesion molecule expression. It protects against gut irradiation injury, experimental gastric cancer, enteropathy, and constipation. It improves nutrient absorption in cystic fibrosis. Misoprostol has utility in acetaminophen and ethanol hepatotoxicity, hepatitis, and fibrosis. It is effective in asthmatics and aspirin-sensitive asthmatic and allergic patients. It lowers cholesterol and severity of peripheral vascular diseases, prolongs survival of cardiac and kidney transplantation, synergizes cyclosporine, and protects against cyclosporine-induced renal damage. It works against drug-induced renal damage, interstitial cystitis, lupus nephritis, and hepatorenal syndrome. It is useful in periodontal disease and dental repair. Misoprostol enhances glycosoaminoglycan synthesis in cartilage after injury. It prevents ultraviolet-induced cataracts and reduces intraocular pressure in glaucoma and ocular hypertension. It synergizes antiinflammatory and analgesic effects of diclofenac or colchicine and has been administered to treat trigeminal neuralgic pain. It reduces chemotherapy-induced hair loss and recovery time from burn injury, and is effective in treating sepsis, multiple sclerosis, and pancreatitis.

The paper is devoted to the actual questions of gastrointestinal immunology. In the first part, structure and function of gut-associated mucosal tissue (GALT), including the role of secretory immunoglobulins and importance of oral tolerance are shown. In the second part, the pathogenesis of unknown origin gastrointestinal and liver diseases (gluten sensitive enteropathy, inflammatory bowel diseases, autoimmune liver diseases, autoimmune pancreatitis) is described. Then the immunology of some gastrointestinal infections (Helicobacter pylori, hepatitis virus B and C, and HIV) and of alcoholic and drug induced, liver diseases is briefly summarized.
