Five feeder pigs 4 to 6 months old were orally inoculated with transmissible gastroenteritis virus. Diagnosis of transmissible gastroenteritis was made on the basis of clinical signs and examination of intestinal mucosa by the fluorescent antibody technique. Immunoglobulins were extracted from intestinal fluid of infected feeder pigs. Virus-binding and neutralizing antibodies were detected in intestinal extracts between 7 and 56 days after infection. The concentration of binding antibodies reached a peak at 21 days after infection and was on the decline at the end of the experiment on the 56th postinfection day. In contrast, neutralizing intestinal antibody concentration was increasing on day 56. In both systems, the predominant immunoglobulin was of the IgA class. Examination of blood serums of the pigs by the plaque-reduction technique showed progressive antibody increases ranging in titer from 1:8 on day 7 to 1:256 on day 56 after infection. An analysis of the protein profiles from these serums showed a significant increase in the concentration of gamma-globulins and a decrease in the albumin fraction.

Two outbreaks of parasitic gastroenteritis were observed in a group of 10 first-season grazing calves, one in mid-July and one in mid-September. In both cases emergency anthelmintic treatment was needed to prevent further damage. Severe clinical signs were observed together with high faecal egg counts and high serum pepsinogen and gastrin concentrations. Low total protein and albumin concentrations were also observed, especially during the second outbreak. The ostertagia antibody levels followed a similar pattern to the serum pepsinogen and gastrin concentrations. At the end of the housing period a mild type II ostertagiasis was observed. In the second grazing season the heifers did not show any signs of parasitic gastroenteritis, but there was a serious outbreak of husk which required treatment.

The intestinal permeability of specific pathogen free piglets has been studied by measuring the concentration of 14C in the blood after oral administration of 14C polyethylene glycol (14C PEG, MW = 4000) and the concentration of 131I in the faeces after intraperitoneal administration of 131I porcine albumin (131I PA, MW = 68,000). The tests were performed one day before and up to two days after the piglets were infected with transmissible gastroenteritis (TGE) virus. Jejunal biopsies were taken from two piglets before the experimental infection, from two piglets 12 h after the experimental infection and from five piglets at the end of the experiment, 46 h after infection. Blood samples were taken six-hourly and faecal samples several times. Some piglets vomited before diarrhoea and loss of appetite started at 14 h after infection; the packed cell volume decreased before but increased after infection. Morphological examination showed hyperregenerative villous atrophy at 46 h after infection. There was no increase in the permeation of 14C PEG but there was a significant increase in the flux of 131I PA from the blood to the gut lumen.

The efficacy of the oxfendazole pulse release bolus system for the control of parasitic gastroenteritis and parasitic bronchitis in first-season grazing calves was evaluated in Belgium. Twenty-two calves were allocated to two groups. The calves in one group received a bolus at the time of turn out, while the other group remained untreated. The efficacy of the bolus was assessed by comparison of faecal worm egg counts, plasma pepsinogen concentrations, the antibody response to Ostertagia, Cooperia and Dictyocaulus species total plasma protein and albumin concentrations, and weight gains throughout the grazing season and the housing period. The oxfendazole pulse release bolus provided good control of parasitic gastroenteritis dominated by ostertagia. The effects of parasitic gastritis were greatly reduced as shown by the significantly lower values of serum pepsinogen and ostertagia antibody titres. The use of the bolus further reduced the adverse effects of parasitism as indicated by better liveweight gains and normal total plasma protein and albumin concentrations whereas in the untreated control group hypoproteinaemia and hypoalbuminaemia were observed. Most animals exhibited clinical signs of parasitic bronchitis at the end of the grazing season, and the bolus may not adequately control parasitic bronchitis in all cases at all times.

The permeability of the intestine of specific pathogen free piglets was investigated by measuring the concentration of 125-I in the blood after oral administration of 125-I polyvinylpyrrolidone (125-I PVP, MW = 40,000 Da) and the concentration of 131-I in the faeces after intravenous administration of 131-I porcine albumin (131-I PA, MW = 68,000 Da). The tests were performed one day before and up to two days after the piglets were infected with the Miller strain of transmissible gastroenteritis (TGE) virus. Biopsies of the jejunum were taken at the end of the experiment and blood samples were taken six-hourly. The piglets became anorexic and had diarrhoea 12 hours after infection; the packed cell volume decreased and the concentrations of urea and total serum proteins increased slightly after infection. However, the marked villous atrophy was not accompanied by an increased permeability of the intestine to PVP or PA.

Alterations in serum ionized and total calcium, magnesium, and phosphate concentrations, during recovery from acute dehydrating gastroenteritis, were studied. Fifteen children with acute dehydrating gastroenteritis had serum concentrations of ionized and total calcium, magnesium, phosphate, sodium, potassium, chloride, urea, creatinine, and albumin, as well as acid-base status, evaluated during rehydration and up to 72-h postadmission. The total serum calcium corrected for albumin did not change significantly during rehydration and remained within the normal range. Although serum ionized calcium fell significantly at 24 and 72 h, its concentration was not sufficiently decreased to cause symptomatic hypocalcemia. Serum ionized calcium correlated significantly with pH (r = -0.57), bicarbonate (r = -0.63), and albumin (r = +0.65), but not with total serum calcium, magnesium, and phosphate. Serum magnesium remained within the normal range during the study period. Serum phosphate was increased on admission (2.64 +/- 0.77 mmol/L), decreased by 12 h (to 0.84 +/- 0.32 mmol/L), and then followed by a gradual increase. This study suggests that changes in serum ionized calcium in dehydrating gastroenteritis are not of clinical significance. However, changes in serum phosphate concentration need further evaluation.

We examined the uptake of bovine serum albumin (BSA) from the intestine into the circulation of 3-week-old piglets infected with transmissible gastroenteritis virus. Transfer of immunoreactive bovine serum albumin (iBSA) from the intestinal lumen into the circulation was enhanced during both the early invasive phase of this viral enteritis (12-h postinoculation) and the diarrheal phase (84-h postinoculation). In some animals, enhanced uptake persisted into the recovery phase, 324 h after inoculation. Gel filtration studies suggested that iBSA had the molecular size characteristic of native BSA; no immunoreactive fragments of BSA were detected. Based on studies of two animals, the half-life of iBSA approximated that of porcine albumin. Further study is required to determine the immunological consequences of the enhanced uptake of protein occurring during viral infection of the intestine.

Random fecal alpha-1-antitrypsin concentration was measured in children with various gastrointestinal diseases and in normal subjects. One hundred fifteen subjects were evaluated: controls (39); chronic inflammatory bowel disease (20); chronic diarrhea (18); acute gastroenteritis (17); allergic gastroenteropathy (5); chronic pancreatic exocrine insufficiency (4); acute gastrointestinal bleeding (4); nonspecific colitis (4); celiac disease (3); and intestinal lymphangiectasia (1). Mean fecal-alpha-1-antitrypsin for the controls was 0.98 mg/g lyophilized stool. All children with celiac disease, allergic gastroenteropathy, lymphangiectasia, nonspecific colitis, acute gastrointestinal bleeding, and 19 of 20 patients with active chronic inflammatory bowel disease had fecal alpha-1-antitrypsin concentrations greater than 2.6 mg/g stool (mean of the controls + 2 SD). These disorders have all been previously documented to cause protein-losing enteropathy by 51Cr-labeled albumin excretion tests. The other study patients had normal fecal alpha-1-antitrypsin excretion when compared with controls. Serial fecal antitrypsin concentrations paralleled disease activity and clinical response to therapy. The results suggest that random fecal antitrypsin concentration is a valuable screening test for mucosal disorders associated with abnormal transmucosal serum protein loss.

Mushroom poisoning, mainly due to the Amanita genus, is an infrequent cause of liver failure in our environment. However, because of its high morbidity and mortality, it constitutes a medical emergency. The characteristic initial symptoms of vomiting, abdominal pain, and diarrhea are nonspecific and may be confused with gastroenteritis. If correct and early treatment is not given, renal and hepatic failure can develop, sometimes requiring liver transplantation. We present three cases of mushroom poisoning, which presented a different clinical course ranging from complete recovery with traditional medical treatment to severe acute liver failure requiring transplantation in one patient and albumin dialysis (molecular absorbent recycling system [MARS]) in another with favorable outcome. Although controlled clinical studies of the treatment of mushroom poisoning are lacking, recommendations based on the experience of various authors have been established. Penicillin G and silymarin seem to be useful. The development of new techniques of extracorporeal detoxification, mainly MARS, may represent an important support system in the treatment of these patients.

The purpose of this study was to investigate clinical and metabolic effects of combined parenteral and oral nutrition compared with parenteral nutrition in young dogs with haemorrhagic gastroenteritis in a prospective clinical study. Dogs with acute gastroenteritis received either parenteral nutrition (group PN, n = 9) or combined parenteral and early enteral nutrition (group EN, n = 10). Infusions were compounded from amino acids, lipids, glucose and electrolyte/glucose solutions [149 g/l glucose, 20 g/l triglycerides, 40 g/l amino acids and 4009 kJ metabolizable energy/l (957 kcal ME/l)], and supplemented with potassium, phosphate and trace elements. Group EN received additionally a hydrolysed diet (74 kJ/kg BW(0.75) on day 2 and 148 kJ/kg BW(0.75) on days 3 and 4). Glucose, triglycerides, protein, albumin, fibrinogen, urea, creatinine, alkaline phosphatase, glutamate dehydrogenase and glutamate pyruvate transaminase were measured before and during the infusions, haematological traits only before the infusions. Statistics included two-factorial anova and subsequent t-test or Wilcoxon test (P < 0.05). All dogs of group EN survived compared with seven of nine patients in group PN. Most dogs in the EN group vomited within half an hour after introduction of oral feeding on day 2 but tolerance for food increased on days 3 and 4. The general health status and faecal and blood parameters of the surviving dogs were similar (P > 0.05) between the groups. In all dogs leucocytes increased during the treatment period, haematocrit and haemoglobin levels declined. Infusions increased blood glucose and triglycerides (P < 0.05); however, no adverse signs were observed. Early enteral nutrition was possible after a short period of adaptation, however, vomiting can be a severe problem. The evaluation of clinical benefits of early enteral nutrition in young dogs with haemorrhagic gastroenteritis requires further investigations.
