男性2型糖尿病血尿酸与颈动脉粥样硬化的相关性研究

目的 探讨男性2型糖尿病患者血尿酸(SUA)水平和颈动脉粥样硬化的关系.方法 收集男性2型糖尿病患者579例,根据SUA水平四分位数分为:95~250、251~302、303~363和364~658 μmol/L 4个组.检测体重指数、血压、血脂、尿素氮、肌酐、HbA1C等相关指标,高分辨血管外超声检测颈动脉血管斑块厚度及颈动脉内膜中层厚度,统计学分析SUA与上述指标的关系.结果 男性2型糖尿病患者随着SUA水平升高颈动脉粥样硬化的检出率逐渐增高(P＜0.05),且斑块厚度也随之逐渐增高(P＜0.05),但与颈动脉内膜中层的厚度无关(P＞0.05).男性2型糖尿病患者年龄、SUA及HbA1C均为颈动脉粥样硬化的危险因素.结论 SUA与颈动脉粥样硬化发生发展可能有关.

Abstract：

Objective To investigate the relationship between the level of serum uric acid(SUA) and carotid atherosclerosis in male patients with type 2 diabetes mellitus(T2DM). Methods A collection of 579 male T2DM patients with or without carotid atherosclerosis were grouped based on quartiles of SUA. Age, SUA, smokers, duration, body mass index(BMI), blood pressure, total cholesterol(TC), triglyceride(TG), high-density lipoprotein cholesterol(HDL-C), low-density lipoprotein cholesterol(LDL-C), blood urea nitrogen(BUN), creatinine(Cr), and HbA1C were determined in all subjects. The plaques in carotid arteries and intima-media thickness(IMT) were measured with high-resolution ultrasound. Results BMI, systolic and diastolic blood pressures, TG, and Cr showed a gradual increase, while HDL-C and HbA1C showed a gradual decrease according to the higher SUA quartiles in male T2DM(P＜0.05). Nevertheless, the detectable rates of smokers, duration, age, TC, LDL-C, and BUN had no relationships with the SUA quartiles(P＞0.05). The detectable rate of carotid atherosclerosis and the thickness of carotid plaque were positively associated with the levels of SUA in male patients with T2DM(P＜0.05). However, intima-media thickness of carotid arteries did not illustrate the correlation with the levels of SUA in male T2DM patients(P＞0.05). Age, HbA1C, and SUA were independent factors of carotid atherosclerosis in these patients by logistic regression(P＜0.05). Conclusion The levels of SUA seems to be associated with the occurrence and development of carotid atherosclerosis in male patients with T2DM.
