Association between serum uric acid level and hypertension in a Chinese elderly rural population

Previous studies have examined the association between elevated serum uric acid (SUA) level and hypertension; however, the association in the Chinese elderly is still uncertain. A cross-sectional study was performed in a rural district of Beijing. A total of 2,397 participants (967 men and 1,430 women) completed the survey. The SUA levels of participants were categorized into four levels using the quartiles (P25, P50, and P75) as cutoff values. Participant was diagnosed as hyperuricemia if the SUA level was ≥417 μmol/L (male) or ≥357 μmol/L (female). Hypertension was defined as systolic blood pressure (BP) ≥140 mmHg and/or diastolic BP ≥90 mmHg and/or receiving antihypertensive drug treatment. Multiple logistic regression was used to estimate the association between SUA and hypertension. We found that higher SUA level was associated with the increased risk of hypertension in both sexes, even after adjusting for potential confounding variables. In total, the risk for having hypertension increased by 0.3% per 1 μmol/L increment in SUA level, increased by 95% for the highest vs. lowest quartile of SUA level, and increased by 111% in the hyperuricemia patients. Moreover, we found that the association was more pronounced in the male participants. There were approximately J-shaped relationships between SUA level (quartiles) and hypertension in all age groups. Higher SUA levels are positively associated with hypertension among the Chinese rural elderly. Further studies are still required to determine the relationship between SUA level and hypertension and to explore its potential biological mechanisms underlying the gender-related association in the elderly population.

Hyperuricemia and albuminuria in patients with type 2 diabetes mellitus

INTRODUCTION. Hyperuricemia is an independent risk factor for kidney dysfunction in diabetic patients. On the other hand, albuminuria is considered as the proxy of early stages of diabetic nephropathy. We investigated the correlation between hyperuricemia and albuminuria in patients with diabetes mellitus. MATERIALS AND METHODS. In a cross-sectional study of 1275 patients (555 men and 720 women) with type 2 diabetes mellitus, serum uric acid and urinary albumin-creatinine ratio were determined. Other metabolic parameters including lipid profile, hemoglobin A1c, glomerular filtration rate, body mass index, blood pressure, blood glucose were assessed, as well. RESULTS. The mean age of the patients was 52.45 ± 10.11 years old. Serum uric acid levels for normoalbuminuric, microalbuminuric, and macroalbuminuric patients were 4.49 ± 1.22 mg/dL, 4.84 ± 1.52 mg/dL, and 6.15 ± 1.68 mg/dL, respectively. Among patients with clinical metabolic syndrome, 233 (27.5%) were in the forth upper quartile of uric acid level (> 5.3 mg/dL), but in diabetic patients without this syndrome, only 80 (18.7%) were in this group. There was a significant relationship between hyperuricemia and serum triglyceride, fasting blood glucose, hemoglobin A1c, glomerular filtration rate, and serum creatinine levels (P < .001). No significant correlation was found between hyperuricemia and cholesterol levels, age, duration of diabetes mellitus, and body mass index. Serum uric acid level correlated positively with urinary albumin-creatinine ratio (P = .04). CONCLUSIONS. We showed that higher serum uric acid concentrations were associated with a greater probability of albuminuria in patients with type 2 diabetes mellitus.     

Is thiazide-produced uric acid elevation harmful? Analysis of data from the Hypertension Detection and Follow-up Program

Interaction of thiazide diuretics and the serum uric acid and creatinine levels was studied in 3693 stepped care participants in the Hypertension Detection and Follow-up Program not receiving treatment at baseline. Among men grouped into quartiles by their level of uric acid at baseline, the upper quartile (average uric acid, 7.7 mg/dL [458 mumol/L]) had an average serum creatinine level of 1.2 mg/dL (106 mumol/L) and the lowest quartile (uric acid, 4.9 mg/dL [291 mumol/L]) had an average serum creatinine level of 1.1 mg/dL (97 mumol/L). Similar findings were present in women. Therapy with chlorthalidone or other thiazide-type diuretics tended to increase levels of uric acid and creatinine, but the increase in both was less in the upper quartile than in the lower quartile. Among individuals who were prescribed uric acid-lowering drugs, the level of serum creatinine increased just as much as in those whose uric acid level was not pharmacologically lowered. Baseline uric acid level was a weak predictor of mortality in men; the introduction of an interaction term for creatinine suggested that this effect was primarily restricted to those with elevated levels of both uric acid and creatinine at baseline. Change in uric acid level at one year after therapy was inversely correlated with mortality in men. There were few episodes of gout (only 15 recorded in five years among 3693 participants at risk). These results suggest that neither the baseline uric acid level nor the change in uric acid level produced by therapy injures the kidney. These results suggest no reason to lower uric acid levels pharmacologically in the treated hypertensive patient who is not gouty. They leave unanswered whether there is a predictive value to baseline uric acid level not explainable by other correlated cardiovascular risk factors.     

Serum uric acid is an independent predictor of metabolic syndrome in a Japanese health screening population

Serum levels of uric acid (UA) are associated with metabolic syndrome (MetS). However, no study has been aimed to investigate whether baseline UA is a predictor of MetS in a Japanese population. The multivariable adjusted hazard ratios (HRs) of MetS through 3 years were calculated for each 1 SD increase in baseline UA, for the higher quartiles of baseline UA compared with the lowest quartile, and for baseline hyperuricemia defined as ≥7.0 mg/dl for men and ≥6.0 mg/dl for women in apparently healthy 1,606 men aged 51.7 ± 9.4 years and 953 women aged 51.6 ± 9.4 years who visited a medical check-up center in Japan. The HRs (95 % confidence interval; p value) were 1.282 (1.097–1.499; 0.002) in men and 1.354 (1.041–1.762; 0.024) in women for 1 SD increase in baseline UA, 2.206 (1.344–3.620; 0.002) in men and 3.110 (1.121–8.627; 0.029) in women for the highest quartile of baseline UA compared with the lowest quartile, and 1.900 (1.376–2.622; <0.001) in men and 2.088 (1.040–4.190; 0.038) in women for baseline hyperuricemia adjusting for the pre-existing components of MetS, age, smoking, drinking, physical activity, use of antihypertensive, antihyperlipidemic, and antidiabetic medications and histories of coronary heart disease and stroke. However, no significant association was found between longitudinal changes in UA and incident MetS. Baseline UA is an independent predictor of MetS in a Japanese health screening population.     

血清尿酸水平和甘油三酯关系的人群研究

目的探讨我国人群中血清尿酸水平和甘油三酯(TG)的关系。方法1999年在北京市自然人群中采用分层随机抽样的方法进行横断面调查。本研究对1239例资料完整者进行了分析。结果在男女两性中,高TG血症患病率随血清尿酸水平的升高呈明显的升高趋势。用分层的方法分别校正体重指数、HOMA指数和饮酒后,发现在同一体重指数水平、HOMA指数水平和饮酒水平的人群中高TG血症患病率均随尿酸水平的升高呈明显的升高趋势。采用logistic回归模型校正了年龄、性别、吸烟、饮酒、体重指数、HOMA指数和总胆固醇等因素后,以尿酸四分位最低层为对照,在尿酸第二、三、四分位层时患高TG血症的OR值分别为1·26(P=0·28)、1·88(P=0·002)、3·36(P<0·001)。结论血清尿酸水平与TG相关,且独立于年龄、肥胖、饮酒和胰岛素抵抗等因素。     

血浆尿酸水平升高并非中国人群二型糖尿病的致病因素

目的探讨血浆尿酸水平升高是否能导致中国人群二型糖尿病的发生。方法青岛港健康研究建立于1999至2000年．共15208例18岁以上港口职工参加。本研究来自于青岛港健康研究2000—2001年体检数据,13665例非糖尿病患者人选,进行详细的问卷调查、体格及生化检查。对所有研究对象按照血浆尿酸水平高低分为4组,进行了平均5．29年随访,观察二型糖尿病的发生情况。结果：754例调查对象发展成为二型糖尿病。在男性,校正年龄因素的影响后。血浆尿酸水平最高组发生糖尿病的风险是最低组的1．47倍（1．19-1．82,〈0．001）,在女性,该值为2．56（1．42-4．62,P〈0．001）．进一步校正吸烟,饮酒,家庭糖尿病史及肾小球滤过率后,得到与上述值接近的结果。但进一步校正基线血糖,血脂、血压及腰围等代谢综合征的组成危险因子后,血浆尿酸水平最高组与最低组比较,发生糖尿病的风险分别是0．82（0．65-1．03,P=0．089）及1．49（0．8-2．77,P=0．210）。结论血浆尿酸水平升高并非中国人群二型糖尿病的主要致病因素。     

Serum uric acid is associated with microalbuminuria in prehypertension

Serum uric acid is associated with cardiovascular disease. However, the independent role of uric acid in the development of cardiovascular disease is uncertain. This study examined the cross-sectional association of serum uric acid level with microalbuminuria among 6771 subjects without diabetes or hypertension. Blood pressure was categorized as prehypertension (systolic blood pressure, 120 to 140 mm Hg or diastolic blood pressure, 80 to 90 mm Hg) and normotension (systolic blood pressure, <120 mm Hg and diastolic blood pressure, <80 mm Hg). Microalbuminuria was found in 4.0% of normotensive subjects (n=4819) and in 7.9% of prehypertensive subjects (n=1952). Prehypertensive subjects with microalbuminuria had higher uric acid level than those with normoalbuminuria (men, 387 [68] mmol/L versus 371 [69] mmol/L; P=0.017; women 286 [56] mmol/L versus 262 [54] mmol/L; P=0.006). However, the difference in serum uric acid level according to the presence or absence of microalbuminuria was not found in the normotensive group. Multiple logistic regression models showed that, in the prehypertensive group, after adjustment for other cardiovascular risk factors, the highest uric acid quartile entailed >2 times greater risk for microalbuminuria than the lowest quartile in both men (odds ratio, 2.12; 95% CI, 1.16 to 3.87) and women (odds ratio, 3.36; 95% CI, 1.17 to 9.69). In the normotensive group, serum uric acid quartile did not show the independent association with microalbuminuria. In conclusion, serum uric acid level was strongly associated with microalbuminuria in prehypertensive subjects.     

Serum uric acid levels predict incident nonalcoholic fatty liver disease in healthy Korean men

The objective of the study was to assess the prospective association between serum uric acid levels and incident nonalcoholic fatty liver disease in a cohort of healthy Korean men. A cohort study was performed on 5741 Korean men, 30 to 59 years of age, with no evidence of fatty liver disease on liver ultrasound and with no major risk factors for liver disease at baseline. Study participants were followed in annual or biennial health examinations between 2002 and 2008. The presence of fatty liver was determined at each examination by ultrasound. Cox proportional hazards models were used to evaluate the association of baseline and time-dependent levels of serum uric acid with incident fatty liver, adjusted for potential confounders. During 23 995 person-years of follow-up, 1717 participants developed fatty liver on ultrasound examination. After adjustment for age, body mass index, smoking, and alcohol intake, the hazard ratios (95% confidence intervals) for incident fatty liver comparing quartiles 2 to 4 of serum uric acid to quartile 1 were 1.17 (1.01-1.37), 1.28 (1.11-1.48), and 1.51 (1.31-1.73), respectively (P for trend = .001). The adjusted hazard ratio comparing participants with hyperuricemia (serum uric acid ≥7.0 mg/dL) to those with normouricemia (<7.0 mg/dL) was 1.29 (1.14-1.46). A graded and statistically significant association persisted after adjusting for other cardiometabolic factors and also in time-dependent models. Serum uric acid was an independent risk factor of incident fatty liver detected by ultrasonography. Additional research should clarify the mechanisms underlying this association and the role of hyperuricemia in the development of fatty liver.     

Serum uric acid and metabolic syndrome in Taiwanese adults

A positive association between serum uric acid and metabolic syndrome has been reported, but little information is available about the association between serum uric acid and metabolic syndrome in Taiwanese adults. The purpose of this study was to investigate the association between serum uric acid levels and metabolic syndrome in Taiwanese adults. We performed a cross-sectional study of 2085 men and 1557 women. All of the participants underwent a health screening during the period from January 2005 to December 2005 at a health center of the Shin Kong Wu Ho-Su Memorial Hospital. Metabolic syndrome was defined according to the National Cholesterol Education Program Adult Treatment Panel III criteria. The results showed that hyperuricemia was significantly associated with increased risk for hypertriglyceridemia, low high-density lipoprotein cholesterol level, and high blood pressure in men and women. The risk of metabolic syndrome was significantly higher in the fourth quartile than in the first quartile of uric acid level in men (odds ratio [OR], 1.50; 95% confidence interval [CI], 1.06-2.14) and women (OR, 2.33; 95% CI, 1.39-3.93). In addition, uric acid level was inversely associated with hyperglycemia in men. The ORs of hyperglycemia for the second, third, and fourth quartile of uric acid were 0.69 (95% CI, 0.46-1.03), 0.55 (95% CI, 0.37-0.83), and 0.45 (95% CI, 0.29-0.69), respectively, compared with the lowest quartile of uric acid. The results demonstrate that there is a positive association between serum uric acid levels and metabolic syndrome and an inverse association between uric acid and fasting plasma glucose in Taiwanese adults.
