| Summary: | Background: Experimental studies revealed pro-inflammatory properties of angiotensin II. We evaluated antiinflammatory effects of the angiotensin II subtype 1 receptor antagonist olmesartan medoxomil alone and in cotherapy with the HMG-CoA reductase inhibitor pravastatin, in patients with essential hypertension and microinflammation. Methods and results: We measured a panel of vascular inflammation markers, including high-sensitivity C-reactive protein (hsCRP), and lipid levels during 12 weeks of therapy with olmesartan (n=100) or placebo (n=99) in a prospective double-blind multicenter study. Pravastatin was added to the double-blind therapy at week 6 in both treatment arms. Blood pressure (BP) control was achieved with addition of hydrochlorothiazide. Olmesartan treatment had already significantly reduced serum levels of hsCRP (-15,1%; p<0,05), high-sensitivity tumor necrosis factor-alpha, hsTNF-alpha (-8,9%; p<0,02), interleukin-6, IL-6 (-14,0%; p<0,05), and monocyte chemotactic protein-1, MCP-1 (-6,5%; p<0,01) after 6 weeks of therapy, whereas placebo treatment (ie, BP reduction) had no major effect on inflammation markers. After 12 weeks of therapy, hsCRP (-21,1%; p<0,02), hsTNF-alpha (-13,6%; p<0,01), and IL-6 (-18,0%; p<0,01) decreased further with olmesartan and pravastatin co-therapy, but treatment with pravastatin alone (ie, co-therapy with placebo) did not significantly alter inflammation markers. In contrast, addition of pravastatin led to a significant (p<0,001) reduction in LDL cholesterol serum concentrations in the olmesartan and placebo treatment groups (-15,1% and -12,1%, respectively). Conclusions: Angiotensin II receptor blockade significantly reduces vascular microinflammation in patients with essential hypertension by as early as week 6 of therapy. This anti-inflammatory action of angiotensin II receptor antagonists may contribute to their beneficial cardiovascular effects. |
