Abstract: | Medical records and histologic sections of 40 cats with acute pancreatitis were reviewed. Two distinct groups of cats with pancreatitis were established by histologic analysis of tissue. Group I (32 cats) had acute pancreatic necrosis (APN). Group 2 (8 cats) had suppurative pancreatitis. Ages of affected cats ranged from 3 weeks to 16 years. l h e majority consisted of indoor cats of the Domestic Short-Haired breed but Siamese cats were over-represented relative to the general population ( P > 0.05). Twenty-two percent of cats were obese and 57%were underweight. Thirty-eight percent of cats had acute disease. In the other cats, two stages in the progression of the disease were evident: (1) anorexia. weight loss, and lethargy, followed by (2) acute deterioration, development of shock, and a moribund state, despite fluid therapy. The most common clinical signs were severe lethargy (100%), reduced appetite (97%), dehydration (92%), and hypothermia (68%). The initial hemogram occasionally showed a neutrophilia (30%) and anemia (2670)but packed cell volume (PCV) decreased markedly to the extent that 555% of cats were anemic terminally. Serum biochemical abnormalities included increased activities of A1, T (68%) and ALP (50%). and increased conrentrations of bilirubin (64%) and cholesterol (64%).Cats with APN were hyperglycemic (64%)), glycosuric (60%) and ketonuric (20%), whereas cats with suppurative pancreatitis tended to be hypoglycemic (7%). Renal failure and electrolyte abnormalities were mild or infrequent escept for hypokalemia (56%)).This study characterizes a severe necrotizing pancreatitis in the cat similar to that reported in other species, and a histologically distinct suppurative pancreatitis. |
