ABSTRACT
BACKGROUND: Human African trypanosomiasis is associated with metabolic changes which have not been well characterized. METHODS: Chlorocebus aethiops were experimentally infected with Trypanosoma brucei rhodesiense and late-stage disease induced at 28 days post-infection. Ear prick blood for glucose determination and blood samples were obtained at weekly intervals for 56 days. Analysis was carried out using dry chemistry analysis. RESULTS: In early infection, there was a significant increase in creatine kinase, while during early and transitional stage of infection there was a significant decrease in glucose and high-density lipoprotein and an increase in triglyceride levels. In the late stage, there was a significant increase in both total cholesterol and LDL levels. CONCLUSIONS: Further investigations should focus on levels of total cholesterol during the follow-up period in curatively treated vervet monkeys. Apart from their importance in disease staging, the changes in lipids levels may also affect the pharmacokinetics of some trypanocides.
