目的

研究获得性免疫缺陷综合征(AIDS)患者颈动脉弹性功能的改变及其影响因素。

方法

随机选取符合入选标准的河南省AIDS患者50例为AIDS组,人类免疫缺陷病毒(HIV)感染病程平均(14.93±3.82)年,均未接受过抗病毒治疗,按照随机对照的原则选取当地健康村民50名为对照组,采用内-中膜自动测量(QIMT)及血管弹性功能定量(QAS)技术检测受试者右侧颈动脉,获得颈动脉内-中膜厚度(IMT)、顺应性系数(CC)、僵硬度(β)和脉搏波传导速度(PWV)。2组间比较采用非配对t检验,相关性分析采用Pearson线性相关分析。

结果

AIDS组与对照组受试者颈动脉IMT比较,差异无统计学意义(P>0.05)。与对照组比较,AIDS组颈动脉CC降低[(0.59±0.21)mm2/kPa vs (1.04±0.41)mm2/kPa)]、β升高(13.01±6.10 vs 8.14±1.37)、PWV升高[(8.70±1.65)m/s vs (6.81±1.37)m/s)],差异均具有统计学意义(P值均<0.05)。HIV感染时间与颈动脉IMT无相关性(r=0.191,P>0.05),与颈动脉弹性参数CC呈负相关,与β、PWV呈正相关(r=-0.575、0.380、0.417,P值均<0.05)。CD4+、CD8+细胞计数与颈动脉IMT、CC、β、PWV均无相关性(r=0.000、1.012,r=-0.093、-0.097,r=0.096、0.012,r=0.056、0.024,P值均>0.05)。

结论

AIDS患者颈动脉弹性功能较正常人减低,且与HIV感谢染时间呈弱的正相关,提示HIV可能在AIDS患者颈动脉弹性功能减低中起一定作用。

Objective

To evaluate the carotid artery stiffness of acquired immune deficiency syndrome (AIDS) and analyze the mechanism and influence factors.

Methods

Fifty cases of AIDS patients and Fifty healthy people were enrolled in this study according to the principles of randomize and control. Quantitive inter-media thickness (QIMT) and quantitive artery stiffness (QAS) technique were employed to evaluate the inter-media thickness (IMT) and stiffness of right carotid artery. The parameters included IMT, compliance coefficent (CC), stiffness β (β), and pulse wave velocity (PWV). Unpaired t test was used to compare the parameters between two groups, and Pearson correlation analysis was used for linear correlation analysis.

Results

There were no statistically difference of carotid artery IMT between two groups [(0.569±0.095) mm vs (0.512±0.114) mm, P>0.05]. There was statistically difference of stiffness parameters (CC, β, PWV) between two groups [(0.59±0.21) mm2/kPa vs (1.04±0.41) mm2/kPa, 13.01±6.10 vs 8.14±1.37, (8.70±1.65) m/s vs (6.81±1.37) m/s, all P<0.05]. There was statistically signification association between HIV-infection time and CC, β, PWV ( r value was -0.575, 0.380, 0.417, all P<0.05 ), but there was no association between HIV-infection time and IMT( r value was 0.191, P>0.05 ). There was no statistically signification association between IMT, CC, β, PWV and CD4+, CD8+ T cell count (r was 0.000, 0.012, -0.093, -0.097, 0.096, 0.012, 0.056, 0.024, all P>0.05).

Conclusions

The carotid artery stiffness of AIDS patients is reduced. HIV may play a role in the development of artery stiffness in AIDS patients.
