高尿酸血症对原发性高血压患者血压水平及胰岛素抵抗的影响

         

摘要

目的:探讨高尿酸血症(HUA)对原发性高血压(EH)患者血压水平及胰岛素抵抗(IR)的影响,并对其病理生理学机制进行分析。方法随机选取2009年4月至2012年3月在南京市大厂医院体检中心接受体检的183例体检者,根据EH和HUA诊断标准,将其分为3组:EH+HUA组(63例)、EH组(60例)、健康对照组(60例)。分别测定收缩压、舒张压、血尿酸、空腹血糖、空腹胰岛素、总胆固醇、三酰甘油、高密度脂蛋白胆固醇,计算胰岛素抵抗指数( HOMA-IR )和β细胞分泌功能指数( HOMA-β),对各组数据进行对比分析。结果①HOMA-IR在EH+HUA组、EH组和对照组间的差异有统计学意义(P<0.05)。②与对照组比较,EH+HUA组和EH组收缩压、舒张压、血尿酸、空腹胰岛素、HOMA-IR均显著升高[(156±12) mmHg (1 mmHg=0.133 kPa),(150±6) mmHg比(133±5) mmHg,(93±6) mmHg,(88±8) mmHg比(80±8) mmHg,(456±26) mmol/L,(330±4) mmol/L比(312±48) mmol/L,(15±5) mU/L,(12±3) mU/L 比(10±3) mU/L,(1.35±0.48),(1.01±0.36)比(0.78±0.27),均 P <0.01],高密度脂蛋白胆固醇则明显降低[(0.89±0.10) mmol/L,(0.92±0.13) mmol/L比(1.04±0.17) mmol/L,P<0.01];EH+HUA组舒张压、空腹血糖、空腹胰岛素、HOMA-IR、总胆固醇、三酰甘油高于 EH 组[(93±6) mmHg 比(88±8) mmHg,(5.58±0.50) mmol/L 比(5.26±0.47) mmol/L,(15±5) mU/L 比(12±3) mU/L,1.35±0.48比1.01±0.36,(5.11±0.53) mmol/L 比(4.85±0.64) mmol/L,(1.57±0.35) mmol/L 比(1.47±0.40) mmol/L,均P<0.05]。结论 HUA可能通过IR机制加重EH及IR;HUA与EH之间存在相互影响。%Objective To explore the effects of hyperuricemia(HUA) on the level of blood pressure and insulin resistance(IR) in essential hypertension(EH) patients,and analyze their features of pathophysiology. Methods A total of 183 cases underwent physical examination in Physical Examination Center of Nanjing Dachang Hospital from Apr.2009 to Mar.2012 were randomly selected as research objects.According to the diagnostic criteria of EH and HUA,all of the cases were divided into three groups:EH and HUA group(63 cases),EH group(60 cases) and control group(60 cases).Systolic blood pressure(SBP),diastolic blood pres-sure(DBP),serum uric acid(SUA),fasting plasma glucose(FPG),fasting insulin(FINS),total cholesterol (TC),triglyceride(TG),high density lipoprotein cholesterol(HDL-C),insulin resistance index(HOMA-IR) and function index of islet beta-cell( HOMA-β) of the three groups were compared.Results ①The differ-ences of HOMA-IR among the three groups were statistically significant( P<0.05 ) .②Compared with the con-trol group,SBP,DBP,blood uril acid,FINS and HOMA-IR in EH+HUA group and EH group increased signif-icantly[(156 ±12) mmHg,(150 ±6) mmHg vs (133 ±5) mmHg,(93 ±6) mmHg,(88 ±8) mmHg vs (80 ±8) mmHg,(456 ±26) mmol/L,(330 ±4) mmol/L vs (312 ±48) mmol/L,(15 ±5) mU/L,(12 ±3) mU/L vs (10 ±3) mU/L,1.35 ±0.48,1.01 ±0.36 vs 0.78 ±0.27,all P<0.01],while HDL-C decreased obviously[(0.89 ±0.10) mmol/L,(0.92 ±0.13) mmol/L vs (1.04 ±0.17) mmol/L(P<0.01)].The lev-els of DBP, FPG, FINS, HOMA-IR, TC and TG in EH +HUA group were higher than those in EH group [(93.27 ±5.52) mmHg vs (87.75 ±8.28) mmHg,(5.58 ±0.50) mmol/L vs (5.26 ±0.47) mmol/L, (15.47 ±4.98) mU/L vs (11.73 ±3.46) mU/L,1.35 ±0.48 vs 1.01 ±0.36,(5.11 ±0.53) mmol/L vs (4.85 ±0.64) mmol/L,(1.57 ±0.35) mmol/L vs (1.47 ±0.40) mmol/L,all P <0.05].Conclusion HUA maybe aggravate EH and IR via mechanism of IR;HUA and EH interacts with each other.
