Alterações da proteína C reativa e fator reumatoide em cães naturalmente infectados por Leishmania spp.

Abstract

Canine visceral leishmaniasis is a zoonosis considered a priority tropical disease. The disease affects various body systems of dogs, including viscera and skin. C-reactive protein (CRP) and rheumatoid factor (RF) are tests performed in medicine for the detection of inflammation and arthritis in humans, however, there are few studies aimed at dogs with leishmaniasis that demonstrate changes in CRP and RF. This work aimed to demonstrate the changes of CRP and RF and its correlation with hyperproteinemia and hyperalbuminemia, in addition to the comparison with the left deviation present in the hematological examination. The work was carried out at the Veterinary Hospital of the University Center of Grande Dourados/MS and Zoonoses Control Center, in which 34 dogs of different breeds and ages were submitted to venous blood collection for immuno-latex exams, Biochemistry and blood count in dogs naturally infected with Leishmania spp. Only dogs to the DPP rapid test for leishmaniasis were used, together with a positive result in parasitological examination, after hematological and biochemical tests were performed. When the test for the quantification of FR in serum was performed, for the 34 animals studied, positivity was observed in only 1 animal, while the dogs were PCR positive in 38.23% of the cases studied. In cases of animals with leishmaniasis it is possible to establish inflammatory levels early, whereas the FR showed not to be a good marker for animals seropositive for the disease.
