    ABSTRACT: Bovine colostrum is a rich source of nutrients, antibodies and growth factors. To examine the efficacy of colostrum enemas in the treatment of distal colitis using a randomized, double-blind, controlled protocol. Fourteen patients (eight female), with a mean age of 45 years (range, 16-75 years) and mild to moderately severe distal colitis (Powell-Tuck scoring system), received colostrum enema (100 mL of 10% solution) or placebo (albumin solution) b.d. for 4 weeks. Both groups also received mesalazine (1.6 g/day) or, if already taking it, had a dose increment of 1.6 g/day. Disease activity was documented at 0, 2 and 4 weeks. After 4 weeks, the colostrum group showed a mean reduction in symptom score of - 2.9 (95% confidence interval (CI), - 5.4 to - 0.3), whereas the placebo group showed a mean response of + 0.5 (95% CI, - 2.4 to +3.4). The histological score improved in five of the eight patients in the colostrum group (mean response, - 0.9; 95% CI, - 1.69 to - 0.03), whereas the histological scores only improved in two of the six patients in the placebo group (mean response, 0.2; 95% CI, - 2.4 to +2.6). Bovine colostrum enema shows potential as a novel therapy for left-sided colitis with additional benefits over using mesalazine alone. Further studies appear to be warranted.

    ABSTRACT: Multiorgan failure is a severe life threatening state where present therapeutic approaches are suboptimal. Epidermal growth factor (EGF) is a potent stimulant of repair in in vitro and in vivo models. We therefore examined its potential beneficial effect in reducing mortality and injury induced by the noxious agent thioacetamide (TAA). Mice (20 per group) were fasted overnight and received a single intraperitoneal dose of human recombinant EGF at 10 or 30 microg/kg or saline (control). Either 30 minutes before or after EGF, all animals also received TAA (40 mg/kg intraperitoneally). Twenty four hours later, surviving animals were killed, tissues collected, and degree of organ injury assessed. Fifty per cent (10/20) of control animals died within the first 24 hour period. Mortality was almost completely prevented by the higher dose of EGF whether given before or after TAA (p<0.01) and was reduced by about 50% with the lower dose of EGF. In control animals, the entire length of the jejunum and ileum had necrosis with or without mucosal denudation. In contrast, necrosis affected only about 10-20% of the total length in EGF treated groups (both p<0.01 v control). Control animals showed marked glomerular tuft collapse, interstitial haemorrhage, and increased plasma creatinine levels. These effects were significantly reduced in animals given EGF (30 microg/kg; p<0.01). All groups showed similar changes in liver histology (centrilobular necrosis) and alanine transaminase levels (10-fold increase). Although EGF did not prevent the hepatotoxicity associated with TAA, it reduced mortality, renal injury, and gastrointestinal damage. These studies provide preliminary evidence that EGF may be a novel approach for the prevention and/or treatment of multiorgan failure.

    ABSTRACT: The glucagon-like peptides (GLP) 1 and 2 are secreted postprandially from L cells located mainly in the ileum. Both hormones prolong intestinal transit and GLP-2 is intestinotrophic in rodents. Patients with a jejunostomy have poor adaptation, rapid gastric and intestinal transit, and impaired postprandial GLP-2 secretion. Ileum resected short bowel patients with a preserved colon show evidence of functional adaptation and have normal gastric emptying. To investigate if GLP-1 and GLP-2 contribute to the positive effects of a preserved colon in short bowel patients by measuring circulating levels of GLP-1 and GLP-2 in seven ileum resected short bowel patients with a preserved colon and seven age and sex matched controls. GLP-1 and GLP-2 immunoreactivity was measured by specific radioimmunoassays in plasma collected at fasting and at regular intervals 180 minutes after a test meal. Median (25-75%) fasting GLP-2 values were 72 (69-105) pmol/l versus 23 (19-27) pmol/l (p=0.001) and meal stimulated area under the curve was 21 078 (14 811-26 610) min x pmol/l versus 11 150 (7151-12 801) min x pmol/l (p=0.01) in short bowel patients with a preserved colon compared with control subjects. Fasting GLP-1 values were 10 (6-12) pmol/l versus 5 (3-5) pmol/l (p=0.01) and meal stimulated area under the curve was 3418 (2966-6850) min x pmol/l versus 2478 (1929-3199) min x pmol/l (p=0.04), respectively. Ileum resected short bowel patients with a preserved colon had elevated fasting plasma concentrations of GLP-1 and GLP-2 and significantly larger meal stimulated areas under the curve compared with age and sex matched controls. Elevated GLP-1 and GLP-2 concentrations may contribute to the positive effects of a preserved colon on intestinal motility and functional adaptation in ileum resected short bowel patients.
