    Notes: Abstract Nineteen consecutive patients with acute pancreatitis were sequentially allocated to treatment with high-dose octreotide (N=9) or to act as controls (N=10). All other aspects of treatment were similar and were according to a strict treatment protocol. There was no significant difference between the two groups on admission with regard to recognized criteria of poor prognosis. The octreotide-treated group required significantly less analgesia and after 48 hr developed significantly fewer poor prognostic indicators, including falls in hematocrit of 〉10%, in serum albumin to 〈32 g/liter, and in serum calcium to 〈2.00 mmol/liter. Falls in arterial PO2 to 〈10 kPa, in serum albumin of 〉20%, and in hemoglobin of 〉2 g/dl were also significantly less frequent. There was a trend towards improvement in the octreotide-treated group in every other physiological and radiological indicator of disease severity. High-dose octreotide may reduce the severity of acute pancreatitis.

    Notes: Abstract To study the early pathogenesis of acute edematous pancreatitis in dogs, we examined the relationship of pancreatic hyperstimulation with cholecystokinin-8 (10 μg/kg/hr intravenously for 6 hr) to alterations in circulating pancreatic enzymes and pancreatic morphology with special reference to trypsinogen activation. Cholecystokinin-8 infusion was associated with increases in plasma amylase, lipase, trypsin-like immunoreactivity, and plasma and urine trypsinogen activation peptide. Pancreatic parenchymal swelling and interlobular and subcapsular fluid accumulations were detected ultrasonographically within 2 hr of cholecystokinin-8. Circulating trypsin-like immunoreactivity and trypsinogen activation peptide in urine reached a peak at 2 and 4 hr, respectively, then declined despite progressive increases in circulating amylase and lipase and intrapancreatic fluid. No significant changes were observed in dogs receiving a saline infusion. This study illustrates that cholecystokinin-8 induces edematous pancreatitis in dogs that is associated with a short-lived burst of trypsinogen activation.
