Abstract
BACKGROUND: Feline hepatic lipidosis (HL) is associated with alterations in lipid and carbohydrate metabolism. The adipokines, adiponectin, and leptin have lipid-lowering and insulin-sensitizing effects. HYPOTHESIS: Serum concentrations of adiponectin and leptin are altered in feline HL. ANIMALS: Client-owned cats: 55 healthy and 45 with liver disease. METHODS: Cats with liver disease were categorized as having HL (n = 20), HL and concurrent disease (n = 19), or other liver disease (n = 6), based on clinical signs, laboratory findings, abdominal ultrasound examination as well as liver cytopathology, histopathology, or both. Serum samples were collected and body condition score determined. RESULTS: Mean serum concentrations of adiponectin were higher in overweight cats with HL (4.5 μg/mL), HL and concurrent disease (4.4 μg/mL), or other liver disease (6.1 μg/mL), as compared with healthy cats (1.5 μg/mL; P < .001, P < .001, and P = .04, respectively). Mean serum concentration of leptin was higher in cats with HL (9.8 ng/mL) or HL and concurrent disease (10.7 ng/mL) than healthy cats (4.9 ng/mL, P < .001 and P < .001, respectively). Cats with other liver disease had leptin concentration (4.9 ng/mL) similar to healthy cats. Concentrations of adiponectin were correlated with alanine aminotransferase activity (r = 0.40, P = .0069), and concentrations of leptin were correlated with alkaline phosphatase activity (r = 0.42, P = .0051) in cats with liver disease. CONCLUSIONS AND CLINICAL IMPORTANCE: Adipokine concentrations are altered in feline HL. Increased concentrations of adiponectin are related to liver disease, whereas increased concentrations of leptin are specifically related to HL.
