[Molecular mechanisms of effects of rosuvastatin on systemic oxidative stress and endogenous inflammation in patients with atherosclerosis].

Aim of the study was to investigate peculiarities of effects of rosuvastatin on the state of oxidative stress and endogenous inflammation in patients with extensive atherosclerosis. Patients with extensive atherosclerosis included into the study (n=46, mean age 56.5 +/- 2.2 years) were distributed to 2 equivalent according to clinico-instrumental data groups. To patients of group 1 (n=24) standard therapy was prescribed (antiaggregants, ACE inhibitors, b-adrenoblockers, and nitrates when indicated), patients of group 2 (n=22) in addition to standard therapy took rosuvastatin (10 mg/day). Investigations included measurement of parameters of serum lipid profile, content of thiol groups of blood serum proteins, activity of enzyme glutathione peroxidase, in vivo oxidation of whole blood serum and HDL, concentration of 3-nitrotirosine, high sensitivity C-reactive protein and interleukin-6, activity of type 2IIA secretory phospholipase A2. It was found that level of 3-nitrotirosine and activity of secretory phospholipase A2 together with high sensitivity C-reactive protein appear to be effective markers of systemic oxidative stress and endogenous inflammation in patients with extensive atherosclerosis. Treatment with rosuvastatin in moderate doses significantly suppressed activity of endogenous inflammation and oxidative stress by way of activation of antioxidant system of plasma, decrease of oxidation of fractions of lipoproteins, suppression of " nitrotirosine " stress, as well as partial inhibition of efficacy of action of secretory phospholipase A2, lowering of content of C-reactive protein and interleukin-6.
