The effect of combining rosuvastatin with sartans of different peroxisome proliferator receptor-γ activating capacity on plasma 8-isoprostane prostaglandin F2a levels

Introduction: Oxidative stress is associated with the development and progression of cardiovascular disease. Plasma 8-isoprostane prostaglandin F-2a (8-iso-PGF(2a)) levels are a reliable marker of oxidative stress. Material and methods: Patients (n = 151) with hypertension, dyslipidemia and impaired fasting glucose were randomly allocated to rosuvastatin (10 mg/day) plus telmisartan 80 mg/day (RT group, n = 52) or irbesartan 300 mg/day (RI group, n = 48) or olmesartan 20 mg/day (RO group, n = 51). After 6 months of treatment, changes in plasma 8-iso-PGF(2a), levels were blindly evaluated. Results: A decrease of 8-iso-PGF(2a), levels vs baseline was observed only in the RT group (-8.6%; p = 0.02). A trend for decrease vs. baseline was observed in the RI (-5.7%; p = 0.40) and RO (-3.7%; p = 0.60) groups. Changes of 8-i50-PGF(2a), levels between groups were not significantly different (p = 0.70). Conclusions: The combination of rosuvastatin with sartans of different peroxisome proliferator receptor-gamma activating capacity was associated with a decrease in levels of plasma 8-i50-PGF2a. This decrease reached significance only in the telmisartan group.
