Background Sepsis is a complex syndrome that involves an increased oxidative stress status and dysregulation of cholinergic neurotransmission. Paraoxonase‐1 (PON‐1) and butyrylcholinesterase (BChE) activities have been identified as significant biomarkers to monitor such disorders in human septic patients. Objective We aimed to determine the diagnostic and prognostic value of PON‐1 and BChE vs other traditional acute‐phase proteins such as albumin (ALB) and C‐reactive protein (CRP) in septic dogs. Methods This prospective observational study included 20 dogs with a diagnosis of sepsis, 27 with low‐grade systemic inflammation (LGSI), and 10 healthy dogs that served as controls. Plasma samples were obtained from all dogs for analysis on admission, and then every 24‐48 hours until discharge or death in the septic group. Results Dogs with sepsis had lower PON‐1 activity compared with dogs in the LGSI group (1.1 ± 0.10 vs 1.6 ± 0.08 U/mL, P = .002), but no differences in BChE activity were detected between the groups. PON‐1, ALB, and CRP could successfully discriminate healthy animals from those with sepsis looking at the area under the curve (AUC) of the receiver operator characteristics curves (ROCs), which were 0.828, 0.903 and 1.000, respectively. Finally, although no differences were found among the groups for PON‐1 or BChE activity, the nonsurvivor septic dogs had higher CRP ( P = .002), lower ALB ( P = .025) levels, and tended to have lower PON‐1 ( P = .082) activities than the survivors at patient death or discharge. Conclusion Septic dogs showed lower plasma PON‐1 and higher BChE activities, but only PON‐1 activity correlated with disease severity. Further studies are warranted to describe the usefulness of these new biomarkers of sepsis progression and recovery in dogs.
