More severe cases may present in [[Shock|shock]], [[Kidney Renal Failure - Pathology#Acute|acute renal failure]], [[Icterus|jaundiced]] (due to focal hepatic necrosis), or with cardiac arrhythmias. Pulmonary oedema, pleural effusions, widespread haemorrhage, [[Disseminated Intravascular Coagulation|DIC]], mild ascites, dehydration (mild to moderate) and pyrexia may also be present.

All pancreatic enzymes increase following [[Kidney Renal Failure - Pathology|renal failure]] (apart from PLI) making it difficult to determine the true cause of the increase. However increases of three fold are mainly due to pancreatitis, whereas five fold increases are rarely not found to be pancreatitis. Rises in lipase, amylase and phospholipase A2 may also be hepatic, gastric, intestinal or neoplastic in origin.

'''In cats:''' Amylase and lipase are of no diagnostic value. Serum feline trypsin-like immunoreactivity (fTLI) is a specific test for exocrine pancreatic function but the test's sensitivity varies between 30% and 60%. In comparison, the serum feline pancreatic lipase immunoreactivity test (fPLI) has been found to be more specific and sensitive in diagnosing feline pancreatitis.
