Canine pancreatic lipase immunoreactivity concentrations associated with intervertebral disc disease in 84 dogs.

OBJECTIVE: To determine the differences in serum canine pancreatic lipase immunoreactivity between dogs with intervertebral disc herniation and healthy control dogs.

MATERIALS AND METHODS: Eighty-four client-owned dogs with intervertebral disc herniation, diagnosed by neurologic examination and imaging, and 18 healthy control dogs. Samples of whole blood were collected within 90 minutes of admission. Serum canine pancreatic lipase immunoreactivity concentrations were measured by a commercial immunoassay and evaluated for association with intervertebral disc herniation, signalment, neurolocalisation and the preadmission administration of glucocorticosteriods or non-steroidal anti-inflammatory drugs.

RESULTS: Serum canine pancreatic lipase immunoreactivity concentrations were statistically increased in dogs with intervertebral disc herniation (P<0·01, n=38). A subgroup of dogs (19/38) with elevated canine pancreatic lipase immunoreactivity concentrations was re-evaluated between 2 and 4 weeks later, and 15 had resolution of clinical signs and values less than 200 μg/L. Serum canine pancreatic lipase immunoreactivity concentrations were not significantly correlated with clinical gastrointestinal disease, neurolocalisation or the preadmission administration of corticosteroids or non-steroidal anti-inflammatory drugs.

CLINICAL SIGNIFICANCE: These results suggest that serum canine pancreatic lipase immunoreactivity concentrations are significantly elevated in dogs with intervertebral disc herniation.
