Chinese Journal of Endocrinology and Metabolism 2011;27(7):543-547
The incidence of hyperuricemia and relevant diseases has been increasing recently since the living improvement and dietary changing. Both patients and doctors do not pay enough attention to this disease, due to the lack of obvious clinical presentations in early stage. This paper comments on the relationship between hyperuricemia and gout, gouty nephropathy, impaired glucose metabolism,and atherosclerotic diseases in order to arouse enough attention to this disease.

Objective To elucidate the relationship between serum uric acid (SUA) and cardiovascular risk factors in Shandong coastal inhabitants. Methods A random, stratified cluster sampling method was conducted. A population.based cross-sectional survey for hyperuricemia was performed and 4 988 dwellers of Shandong coast were investigated. Fasting SUA,lipid profiles,insulin concentrations,etc.,were determined by automatic biochemical analysis device and electrochemiluminescence analyzer.The investigation of general,healthy and nutritional conditions was carried out by questionnaire. Results In male and female subjects, the cardiovascular risk factors such as systolic blood pressure,diastolic blood pressure, selum ereatinine,total cholesterol.triglvceride,waist circumference and body mass index all increased with rising SUA,and the level of senlm high densitv lipoprotein fell accordingly.Homeostasis model assessment insulin resistance index (HOMA- IR) in female subjects increased by the quartile group,not in male subjects.Compared with SUA<280 μmol/L group.odds ratio(OR) values of hypertension in SUA 280-319,320-349,≥350 μmol/L groups were 1.54,1.88 and 2.70 respectively in female,and 2.29,4.15 and 4.96 for metabolic syndrome (MS).As for male,compared with SUA<280 μmol/L group OR value of hypertension in SUA ≥420 μmol/L group was 1.52,and OR values of MS of 1.41,1.87 and 3.27 occurred in SUA 320~379,380~419,≥420 μmol/L groups.After being adjusted for confounding factors,logistic stepwise regression revealed that elevated SUA was an independent risk factor for hypertension in both genders.Conclusion Elevated SUA level is closely related to the incidence and development of cardiovascular diseases,and should not be ignored in clinical practice.

Objective To observe whether high-level insulin increases serum uric acid level and rosiglitazone improves hyperuricemia, and to explore the mechanism. Methods OLETF rats with spontaneous type 2 diabetes complicated with metabolic syndrome and normal control LETO rats were randomly divided into three groups (n=20 each). The animals were fed with standard chow diet in control group, high-purine diet and adenine administered intragastrically in experimental group, and rosiglitazone in interventional group. Body weight, serum levels of uric acid, insulin, triglyceride ( TG ) , and total cholesterol ( TC ) were measured after 3 weeks. Urate transporter 1 ( URAT1 ) and uric acid transporter (UAT) mRNA expressions in renal cortex were examined. HK-2 cells were incubated with various concentrations of insulin for 24 hours. UAT mRNA expression in HK-2 cells was examined. Results ( 1 ) In control group, the insulin level of OLETF rats was significantly higher than that of LETO rats ( P<0. 05 ), and there was no significant difference in serum uric acid level between OLETF and LETO rats. (2)In experimental groups, the insulin level in OLETF rats was significantly higher than that in LETO rats [(61.83±12.13 vs 36.73±12.73 )μIU/ml ,P<0. 05], and the incidence of hyperuricemia (76.92% vs 36.13%,P<0.01 ) and serum uric acid level[( 327.75 ±45.73 vs 264.40±36.32 ) μmol/L, P<0. 01]in OLETF rats were significantly higher than those in LETO rats. (3) Insulin[(41.3± 10.2 vs 61.8±12. 1 )μIU/ml,P<0. 05]and uric acid[( 198.0±45.4 vs 236.9±29.30 ) μmol/L, P<0. 05]levels in OLETF rats in interventional group were significantly lower than those of OLETF rats in experimental group, meanwhile the amount of urinary uric acid excretion was significantly increased[(5 644±371 vs 4 692±278 ) μ mol/L, P<0. 05]. (4) There was no significant difference in insulin level and the expressions of URAT1 and UAT mRNA in renal cortex between OLETF rats in control group and experimental group. URAT1 mRNA expression of OLETF rats in interventional group was significantly decreased, while UAT mRNA expression was significantly increased. (5)With the increase of insulinconcentration in culture medium, the expression of UAT mRNA expression in HK-2 cells was gradually decreased. Conclusions Rosiglitazone may alleviate hyperinsulinemia-induced hyperuricemia via regulating UAT and URAT1 mRNA expression.
