Alcoholic Extract of Lotus Leaves Improves Lipid Profile in Rats with HIV Protease Inhibitor-induced Dyslipidaemia

Journal Authors: 


Objective: To examine the effect of the alcoholic extract of lotus leaves (AELL) on antiretroviral treatment-induced dyslipidaemia in a rat model.

Methods: Lotus leaves were extracted by 95% ethanol. Seventy male Sprague-Dawley rats were given lopinavir/ritonavir for six weeks. At weeks 0 and 6, sera were collected for measurement of total cholesterol (TC) and triglyceride (TG). Rats meeting the criteria for dyslipidaemia were assigned to four groups and received once daily for another four weeks lopinavir/ritonavir (group A), lopinavir/ritonavir plus 0.52 g/kg AELL (group B), lopinavir/ritonavir plus 0.26 g/kg AELL (group C), or lopinavir/ritonavir plus 0.13 g/kg AELL (group D), respectively. At weeks 8 and 10, blood samples were collected again for measurement of TC and TG.

Results: Both TC and TG increased over time in group A during the observation period (weeks 6 to 10), however, TC and TG decreased in group B, and TG declined in group C. Neither TC nor TG could be reduced to a level near baseline.

Conclusion: Alcoholic extract of lotus leaves may have the potential to treat dyslipidaemia related to highly active antiretroviral treatment, but may not be potent enough to reduce TC or TG concentrations to goal levels when used alone.
