Background: Asymmetric dimethylarginine (ADMA) has been proposed as a severity
marker in humans with acute pancreatitis (AP).
Objectives: To evaluate ADMA in dogs with AP compared with healthy dogs and its
association with severity of disease, mortality, and indicators of the systemic inflammatory response syndrome (SIRS), including serum C-reactive protein (CRP) concentration, WBC count, and band neutrophils.
Animals: Fifty-four dogs with AP and a control group (CG) of 28 healthy dogs.
Methods: Cohort study including dogs with AP diagnosed using clinical and laboratory variables, abnormal canine pancreatic lipase (cPL) concentration, and compatible
abdominal ultrasound examination findings performed within 48 hours of admission.
Canine AP severity (CAPS) was calculated. Serum concentration of ADMA was measured using high performance liquid chromatography. Blood donor-, staff-, and
student-owned dogs were enrolled in the CG.
Results: Dogs with AP had higher median admission serum ADMA concentrations
compared with the CG (62 versus 48.5 μg/dL; P = .003). Dogs with CAPS ≥11 had
higher serum ADMA concentrations than did dogs with CAPS <11 (92 versus
54.6 μg/dL P = .009). Univariable analysis for mortality, CAPS score, band neutrophils, CRP, and ADMA were included in multivariable logistic regression, in which
only ADMA was associated with mortality (P = .02). Survivors had a significant
decrease in ADMA at first reevaluation compared to admission (P = .02).
Conclusions and Clinical Importance: Because serum ADMA concentrations were
higher in AP dogs compared with the CG, it may have value as a biomarker in the
diagnosis of AP in dogs. In addition, because ADMA was associated with mortality, it
may have prognostic value.
