Similarly, dogs with MODS had significantly lower serum Apo-A1 concentrations (104.1 +/- 4.6 mg/dl) and higher APPLE(fast) score values (31, 13-38) compared to those without MODS (118.32 +/- 2.1 mg/dl and 26, 6-33, respectively) (P = 0.0050 and P = 0.0038, respectively).

Abstract

IntroductionApolipoprotein-A1 (Apo-A1) acts as a negative acute phase protein (APP) during inflammatory states, and has a potential prognostic value in people and dogs with sepsis. The aim of this retrospective study was to investigate the association of serum Apo-A1 concentration with disease severity, multiorgan dysfunction syndrome (MODS) and outcome in a population of dogs with sepsis, and to assess its correlation with major canine APPs. MethodsNinety-nine dogs with uncomplicated sepsis (n = 78) or septic shock (n = 21) were included. The serum concentration of Apo-A1, C-reactive protein (CRP) and serum amyloid A (SAA) were recorded, alongside the canine acute patient physiologic and laboratory evaluation fast (APPLE(fast)) score and the presence of MODS. ResultsDogs with septic shock had significantly lower serum Apo-A1 concentrations (106.3 +/- 22.7 mg/dl; reference interval: 123.0-142.3 mg/dl), higher APPLE(fast) score (30, 13-38) and greater frequency of MODS (67%) compared to those with uncomplicated sepsis (117.9 +/- 19.3 mg/dl; 25, 6-33 and 8%, respectively) (P = 0.0201; P = 0.0005; P < 0.0001, respectively). Similarly, dogs with MODS had significantly lower serum Apo-A1 concentrations (104.1 +/- 4.6 mg/dl) and higher APPLE(fast) score values (31, 13-38) compared to those without MODS (118.32 +/- 2.1 mg/dl and 26, 6-33, respectively) (P = 0.0050 and P = 0.0038, respectively).
