OBJECTIVE
The purpose of the study was to investigate the oxidative status and lipid profile among dogs at different stages of visceral leishmaniasis (VL).
METHODS
Dogs with VL were divided into four groups according to the classification reported by the Leishvet group: stage I (n=9), stage II (n=11), stage III (n=6), and stage IV (n=6); these dogs were compared to healthy control dogs (n=14). The lipid profile [high-density lipoprotein (HDL), low-density lipoprotein (LDL), cholesterol, and triglyceride levels) and oxidative status [total antioxidant capacity (TAC), total oxidant status (TOS), and paraoxonase-1 (PON-1) activity] were evaluated.
RESULTS
Compared to the control dogs, significant increases in the TOS and the LDL level and decreases in PON-1 activity and the HDL level were determined among the dogs at all stages of VL (p<0.05). No significant differences were found in the TAC and the cholesterol and triglyceride levels among the groups.
CONCLUSIONS
Increased oxidative stress and alterations in lipid profile were observed among dogs with VL. However, no significant differences were detected between dogs at different stages of the disease. Therefore, changes in the TOS, PON-1 activity, and HDL and LDL levels in dogs at all stages of VL should be considered in the diagnosis of the disease and planning of the treatment.
