Abstract

BACKGROUND: Dogs with protein-losing enteropathy (PLE) are at risk of developing a hypercoagulable state, but the prevalence of hypercoagulability in dogs with chronic enteropathies (CE) and normal serum albumin concentration is unknown.

HYPOTHESIS: Dogs with CE are predisposed to a hypercoagulable state as assessed by thromboelastography (TEG) independent of serum albumin concentration.

METHODS: Dogs with chronic gastrointestinal signs from suspected inflammatory CE between 2017 and 2019 were included. Thirty-eight were evaluated; every dog had a CBC, serum biochemistry panel, and abdominal imaging performed. The Canine Inflammatory Bowel Disease Activity Index (CIBDAI) was calculated. Thromboelastography was performed at presentation, and reaction time (R), kinetic time (K), α-angle, maximal amplitude (MA), and global clot strength (G) were recorded. Dogs were considered hypercoagulable if the G value was ≥25% above the reference interval.

RESULTS: Seventeen of 38 (44.7%; 95% confidence interval [CI], 28.6-61.7%) dogs with CE were hypercoagulable. The G value did not differ between the 19 dogs with normal (≥28 g/L) serum albumin concentrations (9.05 kdyn/cm2 ; 95% CI, 7.26-10.84; SD 3.71) and 19 dogs with hypoalbuminemia (11.3 kdyn/cm2 ; 95% CI, 9.04-13.6, SD; 4.7; P = .11). The G value was negatively correlated with hematocrit, serum albumin concentration, and duration of signs and positively correlated with age.

CONCLUSIONS AND CLINICAL IMPORTANCE: Dogs with CE and normal serum albumin concentration can be hypercoagulable as measured by TEG.
