Serum cardiac troponin I concentrations in naturally occurring myelosuppressive and non-myelosuppressive canine monocytic ehrlichiosis.

摘要

The aim of this study was to determine whether serum cardiac troponin I (cTnI) concentration measured on admission was associated with the clinical severity of canine monocytic ehrlichiosis and was predictive of clinical outcome (death or survival) in dogs naturally infected with Ehrlichia canis. Serum cTnI concentration was compared among 22 dogs with non-myelosuppressive ehrlichiosis (NME), 22 dogs with myelosuppressive ehrlichiosis (ME) and 10 healthy dogs. Unlike healthy dogs, 45.5% NME and 59.1% ME dogs had increased cTnI concentrations. There was no difference in the frequency of cTnI increase or mean cTnI concentrations between the NME and ME groups, whereas mean cTnI concentration was significantly lower in healthy dogs. No association was established between cTnI concentration on admission and clinical outcome.Digital Object Identifier http://dx.doi.org/10.1016/j.tvjl.2012.04.008
