Abstract
The objective of the present study was to investigate the role of thyroid hormones and lipid profile in development and outcome of canine visceral leishmaniosis (CVL). We therefore studied the relationships between blood serum thyroid hormones [total T4, free T4, total T3, and free T3], lipids, and lipoproteins [total cholesterol, triglyceride, low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C)] and clinical status in dogs naturally infected with Leishmania infantum. Two groups of Leishmania-infected dogs [with no clinical signs (NCS; n = 15), and with clinical signs (CS; n = 16)] were assessed and compared with a group of healthy control dogs (n = 15). A significant decrease in serum total T4 (p < 0.05) concentration in the CS group was observed when compared to the NCS and control groups. The dogs in CS group revealed a significant decrease (p < 0.05) in free T4 concentration in comparison to the control group. The CS group presented a significant decrease in HDL-C (p < 0.01) concentrations, when compared to NCS and control groups. The observed findings in the present study suggested that thyroid hormone and lipoprotein alterations may have a role in susceptibility of dogs with Leishmania infection.
