Abstract

The aim of this study was to evaluate the relationship between arterial stiffness determined by pulse wave velocity (PWV) and serum endogenous androgen concentrations as well as major cardiovascular risk factors in men with type 2 diabetes mellitus. Serum free testosterone and dehydroepiandrosterone sulfate (DHEA-S) concentrations were measured in 268 men with type 2 diabetes mellitus. Relationships between PWV and serum endogenous androgen concentrations as well as major cardiovascular risk factors, including age, blood pressure, serum lipid concentration, glycemic control (hemoglobin A(1c)), body mass index, and degree of albuminuria, were evaluated. Positive correlations were found between PWV and age (r = 0.491, P < .0001), duration of diabetes (r = 0.320, P < .0001), systolic blood pressure (r = 0.292, P < .0001), and log (urinary albumin excretion) (r = 0.269, P < .0001). Inverse correlations were found between serum free testosterone concentration and PWV (r = -0.228, P = .0003) and between serum DHEA-S concentration and PWV (r = -0.252, P = .0002) in men with type 2 diabetes mellitus. Pulse wave velocity was significantly greater in patients with lower concentrations of free testosterone (<10 pg/mL) than in patients with higher concentrations of free testosterone (1864 +/- 359 vs 1736 +/- 327 cm/s; P = .0053). Pulse wave velocity also was significantly greater in patients with lower concentrations of DHEA-S (<1000 ng/mL) than in patients with higher concentrations of DHEA-S (1843 +/- 371 vs 1686 +/- 298 cm/s; P = .0008). Multiple regression analysis identified both serum free testosterone concentration (beta = -.151, P = .0150) and serum DHEA-S concentration (beta = -.200, P = .0017) as independent determinants of PWV. In conclusion, serum endogenous androgen concentrations are inversely associated with arterial stiffness determined by PWV in men with type 2 diabetes mellitus, which is true for men in general based on other works.
