Associação da carga parasitária renal com achados laboratoriais em cães com leishmaniose visceral

Abstract

Canine visceral leishmaniasis is a severe disease and the death occurs from renal failure, whereas conventional diagnostic methods do not allow the animal clinical staging. The aim of this study was to associate the renal parasite load to clinical and histopathological findings in dogs with visceral leishmaniasis. Microscopic analysis revealed a predominance of mononuclear interstitial nephritis of varying degrees in 59, 3% of dogs evaluated. However, no difference was found between the renal parasite load of symptomatics and oligosymptomatics (P= 0,35). Renal lesions were inflammatory order and amount of parasites not influenced the characteristics of theses lesions nor biochemical changes, even in dogs with different clinical classifications.
