摘 要:目的观察睾酮补充治疗对中老年男性颈动脉内膜中层厚度(IMT)的影响。方法选取2008年10月至2011年11月在我院保健中心及门诊体检血清睾酮水平低且伴有IMT增厚的男性患者80例,随机分为两组,治疗组38例予以睾酮补充治疗,对照组42例,未处理并观察1年,检测治疗前后睾酮和IMT的变化,以及分析两者的相关性。结果对照组与治疗组在治疗前的睾酮分别为(10.39±1.44)nmol/L和(10.88±1.87)nmol/L,IMT分别为(1.25±0.11)mm和(1.24±0.13)mm,两组间差异无统计学意义(t=1.32、-0.26,P=0.191、0.794)。治疗1年后,与治疗前相比,治疗组睾酮显著增加,为(22.83±1.56)nmol/L;IMT降低,为(1.18±0.16)mm(t=-29.14、2.55,P=0.000、0.015)。而对照组的睾酮和IMT分别为(9.99±1.72)nmol/L、(1.27±0.11)mm,与治疗前的差异无统计学意义(t=1.24、-1.00,P=0.219、0.323)。线性相关分析显示,睾酮与IMT呈负相关(r=-0.605,P=0.000);多元逐步回归分析显示,睾酮为IMT的独立影响因素(P〈0.05)。结论睾酮补充治疗是缓解中老年男性IMT增厚的一种有效方法,其在改善中老年男性心血管疾病危险因素方面具有重要价值。Objective To investigate the effects of testosterone (T) replacement therapy (TRT) on carotid artery intima-media thickness (IMT) in middle aged and elderly male patients. Methods A total of 80 middle aged and elderly male patients with testosterone deficiency and increased carotid artery IMT were selected and randomly divided into two groups: the treatment group (n=38, treated with testosterone for 1 year) and the control group (n 42, without any treatment). The serum T level, IMT and prostate-specific antigen (PSA) before and after treatment were determined. The correlation between the testosterone level and carotid artery IMT was analyzed. Results There were no significant differences in the serum T level and IMT between the control group and the treatment group before treatment [(10. 39±1. 44) nmol/L vs. (10.88±1.87) nmol/L, (1.25±0.11) mm vs. (1.24±0.13) mm, t=1.32, -0.26, P=0.191, 0.7941. Compared with pretreatment, the serum T level was significantly increased and the IMT was significantly decreased in the treatment group after TRT [(10. 88±1. 87) nmol/L vs. (22.83±1.56) nmol/L, (1. 24±0.13) mm vs. (1.18±0. 16) mm, t=29. 14, 2.55, P=0. 000, 0. 0151, while no significant differences in the serum T level and IMT were found in the control group before and after treatment ((10. 39±1. 44) nmol/Lvs. (9.99±1.72) nmol/L, (1.25±0.11) mm vs. (1.27±0.11) ram, t=1.24, -1.00, P = 0. 219, 0. 323]. Linear correlation analysis showed that the serum T level was negatively correlated with IMT (r=-0. 605, P=0. 000) and multiple regression analysis showed that the T level was an independent factor for IMT. Conclusions Testosterone replacement therapy is an effective treatment to alleviate IMT in middle aged and elderly male patients, which may play an important rolein preventing cardiovascular diseases in middle-aged and elderly male patients.
