    Background/AimHypercholesterolemia is characterized by changes in lipid profile, nitric oxide pathway, and oxidative stress markers, but functions of high-density lipoprotein (HDL) were not well established in hypercholesterolemic subjects treated with atorvastatin. In this study, we aimed to evaluate effects of atorvastatin treatment on functionality of HDL, oxidative stress, and endothelial functions in hypercholesterolemic subjects.Materials And MethodsThirty patients (20 females, 10 males) aged from 40 to 60 years and diagnosed as hypercholesterolemic were included. Patients were treated with 10 mg/day atorvastatin for 3 months. Markers of endothelial functions, namely asymmetric dimethylarginine (ADMA), homocysteine, and nitric oxide (NO), and markers of oxidative status, namely malondialdehyde (MDA), antioxidant potential (AOP), paraoxonase 1 (PON1), and arylesterase, were measured. Before and after atorvastatin treatment, glucose, lipid parameters, and antioxidant/antiinflammatory HDL levels were also measured.ResultsADMA and homocysteine levels were decreased whereas NO levels were increased with atorvastatin therapy. MDA levels were decreased but AOP, PON1, and arylesterase levels and antinflammatory characteristics of HDLs were increased. Furthermore, lipid profiles of the patients improved with atorvastatin therapy.ConclusionHypercholesterolemia is a cause of oxidative stress, endothelial dysfunction, and proinflammatory HDL levels. Atorvastatin is a beneficial pharmacological modulator of impaired antiinflammatory HDL-C levels, endothelial functions, and oxidative status against atherosclerosis indicating pleiotropic effects of statins.
