CLINICAL PATHOLOGY The Clinical Utility of Specific Canine Pancreatic Lipase (Spec cPL™) Dr Remo Lobetti BVSc MMedVet(Med), ECVIM(CA) Bryanston Veterinary Hospital, 011 706 6023 Pancreatitis is a relatively common disease with very non-specific clinical signs such as abdominal pain, anorexia, vomiting and diarrhoea. Currently there is no very specific and sensitive test available to use as a gold standard for diagnosis. Pancreatitis may present as acute and fulminant or be more low grade and chronic in nature. These forms will present with different clinical signs and also cause a different degree of cell damage and resultant lipase release by the affected organ, depending on the degree of inflammation, amount of fibrosis and number of cells remaining and affected. In a case series of canine random consecutive post mortems the most common pancreatic lesion was hyperplastic nodules (80.2%), followed by lymphocytic inflammation (52.5%), fibrosis (49.5%), atrophy (46.5%), neutrophilic inflammation (31.7%), pancreatic fat necrosis (25.7%), pancreatic necrosis (16.8%), and oedema (9.9%). The most common lesion, lymphocytic inflammation, was mild in most cases. This could Dr Liesel van der Merwe BVSc (Hons) MMedVet (Med) Small Animals.) help explain why histologic lesions may be more prevalent than clinical signs of pancreatic disease.5 Clinically normal dogs have low circulating concentrations of pancreatic lipase in the blood. On the other hand, dogs with acute pancreatitis typically show dramatic elevations in serum pancreatic lipase concentrations, which remain elevated for a prolonged period. Animals with low-grade, histopathological disease may not show any dramatic elevations in serum lipase and may even exhibit no clinical signs.5 Pancreatitic lipase can be determined by either the spec cPL or SNAP cPL test. The former is a laboratory run test,
