Clinical significance of blood cell ratios in healthy and sick Leishmania infantum-seropositive dogs.
Background: The accuracy of blood cell ratios (BCRs) as cost-effective and easily accessible diagnostic and prognostic markers of inflammatory conditions has been investigated in veterinary medicine in recent years.
Methods: Neutrophil-to-lymphocyte (NLR), monocyte-to-lymphocyte (MLR), and platelet-to-lymphocyte (PLR) ratios were studied in 195 dogs clinically evaluated and tested for anti-Leishmania infantum (Li) antibodies (Li-seronegative (Li-), n = 10; Li-seropositive clinically healthy (Li+healthy), n = 100; Li-seropositive with clinical and/or clinicopathological abnormalities (Li+sick), n = 85). The Li+sick dogs were classified in LeishVet stages IIa/IIb (Li+IIa/IIb) (n = 66) and III/IV (Li+III/IV) (n = 19). BCR relationships with LeishVet clinical stage, antibody levels, and serum protein electrophoretic fraction concentrations were investigated.
Results: Higher NLR values were found in Li+, Li+healthy, and Li+IIa/IIb sick dogs compared to Li- dogs (P < 0.001). Higher NLR and MLR were found in Li+sick (NLR, P < 0.001; MLR, P = 0.034) and Li+III/IV dogs (NLR, P < 0.001; MLR, P = 0.005) compared to Li- dogs, and in Li+III/IV dogs (NLR, P = 0.002; MLR, P < 0.001) compared to Li+healthy. All three BCRs were higher in Li+sick (NLR, MLR, P < 0.001; PLR, P = 0.023) and Li+IIa/IIb dogs (NLR P < 0.001; MLR P = 0.001; PLR, P = 0.012) compared to Li+healthy dogs. The BCRs failed to distinguish dogs with moderate (Li+IIa/IIb) and severe or very severe disease (Li+III/IV). BCRs demonstrated weak positive correlations with serum globulin fractions and antibody levels, and weak negative correlations with serum albumin level were found. Li+sick dogs presenting hypoalbuminemia showed higher MLR ratios (P = 0.001) than those with normal albumin values.
Conclusions: This study shows that BCR measures provide useful information for differentiating antibody-positive healthy and sick dogs at diagnosis. Dogs with hypoalbuminemia showed higher MLR values despite monocytosis being very rare.
期刊介绍:
Parasites & Vectors is an open access, peer-reviewed online journal dealing with the biology of parasites, parasitic diseases, intermediate hosts, vectors and vector-borne pathogens. Manuscripts published in this journal will be available to all worldwide, with no barriers to access, immediately following acceptance. However, authors retain the copyright of their material and may use it, or distribute it, as they wish.
Manuscripts on all aspects of the basic and applied biology of parasites, intermediate hosts, vectors and vector-borne pathogens will be considered. In addition to the traditional and well-established areas of science in these fields, we also aim to provide a vehicle for publication of the rapidly developing resources and technology in parasite, intermediate host and vector genomics and their impacts on biological research. We are able to publish large datasets and extensive results, frequently associated with genomic and post-genomic technologies, which are not readily accommodated in traditional journals. Manuscripts addressing broader issues, for example economics, social sciences and global climate change in relation to parasites, vectors and disease control, are also welcomed.
