Serum adipokine concentrations in dogs with acute pancreatitis.

BACKGROUND: Limited information is available about the role of adipokines in the development and progression of acute pancreatitis (AP) in dogs. OBJECTIVES: To determine whether the circulating concentrations of adipokines differed between healthy dogs and dogs with AP, and whether the circulating concentrations differed between AP survivors and AP nonsurvivors. ANIMALS: Twenty-eight healthy dogs and 25 client-owned dogs with AP. METHODS: Prospective observational cohort study of 25 client-owned dogs with newly diagnosed AP and 28 otherwise healthy dogs with similar body condition scores. The serum concentrations of leptin, adiponectin, resistin, visfatin, interleukin (IL)-1ß, IL-6, IL-10, IL-18, and tumor necrosis factor (TNF)-α were measured. RESULTS: The serum concentrations of leptin (P = .0021), resistin (P = .0010), visfatin (P < .0001), IL-1ß (P < .0001), IL-6 (P = .0002), IL-10 (P < .0001), and IL-18 (P < .0001) were significantly higher in dogs with AP than healthy dogs, whereas the adiponectin concentration (P = .0011) was significantly lower. There were significant differences in the serum concentrations of leptin (P = .028) and adiponectin (P = .046) in survivors and nonsurvivors. After the disappearance of clinical signs, the concentrations of resistin (P = .037) and IL-1ß (P = .027) decreased significantly, whereas the serum concentrations of leptin (P > .999), adiponectin (P = .11), visfatin (P = .83), IL-6 (P = .82), IL-10 (P = .82), IL-18 (P = .56), and TNF-α (P = .94) did not differ significantly. CONCLUSION AND CLINICAL IMPORTANCE: This study showed that dysregulation of adipokines might be involved in the pathogenesis of AP. In addition, leptin and adiponectin are likely to be associated with mortality rate in AP.
