Abstract

BACKGROUND AND AIM:

Previously, we have shown that slightly to moderately aged arteries in middle-aged males can be rejuvenated functionally by sub-therapeutic, low-dose fluvastatin and valsartan treatment. Here, we explore whether this treatment could also increase telomerase activity. We hypothesized that telomerase activity might be associated with (1) an improvement of arterial wall properties and (2) a reduction of inflammatory/oxidative stress parameters (both observed in our previous studies).

METHODS:

The stored blood samples from 130 apparently healthy middle-aged males treated with fluvastatin (10 mg daily), valsartan (20 mg daily), fluvastatin and valsartan combination (10 and 20 mg), respectively, and placebo (control), were analyzed. The samples were taken before and after treatment lasting 30 days, and 5 months after treatment discontinuation. Telomerase activity was measured in blood leukocytes by a TaqMan Gene Expression Assay.

RESULTS:

Low-dose fluvastatin or valsartan increased telomerase activity (106.9% and 59.5% respectively; both p < 0.05, vs. control), whereas their combination was even more effective (an increase of 228.0%; p < 0.001, vs. control). No change was noted in the control group. Importantly, increased telomerase activity obtained in the combination group significantly correlated with arterial function, measured by flow-mediated dilation (FMD) (r = 0.79; p < 0.001) and C-reactive protein concentration (r = -0.54; p = 0.02) and total anti-oxidative status (r = 0.50; p = 0.03).

CONCLUSION:

We found that a low-dose combination of fluvastatin and valsartan substantially increased telomerase activity, which significantly correlated with an improvement of endothelial function and a decrease of inflammation/oxidative stress. These findings could lead to a new innovative approach to arterial rejuvenation.
