OBJECTIVETo analyze the relationship between hyperuricemia and primary nephrotic syndrome in childhood.

METHODA retrospective study was carried out in 107 children with primary nephrotic syndrome. The clinical data were analyzed with statistical methods to identify the related factors with hyperuricemia.

RESULTThe morbidity of hyperuricemia in children with primary nephrotic syndrome was 45% (48/107). Compared to those in normal serum uric acid group, the incidence of hypertension (33%, 16/48), serum triglyceride [2.59(1.62-3.87) mmol/L], creatinine [43.85(33.38-56.38)mmol/L], urea [6.11(3.77-8.40)mmol/L] and blood uric acid/creatinine ratio [9.30(7.03-12.72)] increased while creatinine clearance rate [141.74(103.57-160.97)ml/(min·1.73 (2))] decreased in hyperuricemia group.

CONCLUSIONHyperuricemia in children with primary nephrotic syndrome correlated with the increase of serum creatinine, urea and blood uric acid/creatinine ratio, the decrease of creatinine clearance rate and the occurance of hypertension.

OBJECTIVE: The purpose of this study was to determine the serum uric acid levels and the prevalence of hyperuricemia among Chinese adults in 2015 and compare the differences between urban and rural areas, as well as the differences between eastern, central, and western regions. METHODS: A national representative sample of 180,208 participants were included using a stratified, multistage, and random sampling method. The demographic characteristics and blood samples were collected to determine the serum uric acid levels and prevalence of hyperuricemia among subgroups using complicated sampling weight. A t-test or ANOVA was used for normally-distributed data. The Kruskal-Wallis rank test was used for skewed-distributed data. The Mantel-Haenszel chi-square test was used to compare the difference in categorical variables. RESULTS: The weighted mean uric acid level in Chinese adults was 310.4 μmol/L (317.5 μmol/L in urban areas and 302.9 μmol/L in rural areas). The weighted average values of uric acid in eastern, central, and western China were 315.5 μmol/L, 303.5 μmol/L, and 310.4 μmol/L, respectively. The weighted prevalence of hyperuricemia in Chinese adults was 14.6%, with a prevalence of 16.5% in urban areas and 12.5% in rural areas. The weighted prevalence of hyperuricemia in eastern, central, and western China was 16.0%, 12.5%, and 14.8%, respectively. CONCLUSION The uric acid level in Chinese adults is relatively high. Effective actions are warranted to improve this metabolic abnormality.

OBJECTIVETo study the relationship between compositions of hyperuricemia and metabolic syndrome among residents aged > or =20 years.

METHODSA stratified cluster sampling was conducted with 7887 dwellers recruited and examinaed. Blood samples were then collected for serum detection. Available data was analyzed using SPSS 13.0.

RESULTSThe incidence rates of obesity, hypertension and hyperglycemia for hyperuricemia were 53.4% with OR = 2.568 (95% CI: 2.103-3.137), 38.8% with OR= 2.157 (95% CI: 1.856-2.508) and 21.9% with OR = 1.850 (95% CI: 1.552-2.205) respectively. Along with the increase of uric acid, body mass index changed the most followed by triglyceridemia. The change of hyperglycemia for men and cholesterol for women were not prominent. Conclusion The relationship between compositions of hyperuricemia and metabolic syndrome was close, suggesting that hyperuricemia might serve as one of the compositions of metabolic syndrome and could contribute to the prevention and control of cardiovascular and cerebrovascular diseases.

Objective: To understand the prevalence of chronic kidney disease (CKD) and related factors in adults in Anhui province based on the data of Chinese Chronic Diseases and Nutrition Surveillance program (2018) in Anhui. Methods: Multi-stage stratified cluster random sampling was used to select participants aged ≥18 years. Moreover, questionnaire survey, body measurements and laboratory tests were conducted. The complex weighting method was used to estimate the prevalence of CKD in residents with different characteristics, and complex sampling data logistic regression model was used for multivariate analysis to identify related risk factors. Results: A total of 7 181 participants were included. The overall prevalence of CKD was 11.06% in adults in Anhui, and the prevalence was 12.49% in women and 9.59% in men (P<0.05). The moderate, high and very high risk for CKD progression were 8.66%, 2.02% and 0.38%, respectively. Multivariate analysis showed that age (OR=1.03, 95%CI: 1.00-1.05), BMI (OR=1.05, 95%CI: 1.01-1.09), being woman (OR=1.38,95%CI: 1.22-1.55), hypertension (OR=2.50, 95%CI: 1.76-3.56), diabetes (OR=2.28, 95%CI: 1.51-3.43), dyslipidemia (OR=1.26, 95%CI: 1.11-1.43) and hyperuricemia (OR=2.16, 95%CI: 1.68-2.78) were risk factors for CKD. Conclusion: The prevalence of CKD in adults in Anhui was relatively high and age, gender, BMI, hypertension, diabetes, dyslipidemia and hyperuricemia were found to be associated with the prevalence of CKD. To prevent CKD and its complications, attention should be paid to the management of related risk factors, including overweight and obesity, hypertension, diabetes, dyslipidemia and hyperuricemia.

We studied about 437 patients(620 hips) who were diagnosed osteoncrosis of the femoral head in Kyung Hee University Hospital during last 15 years and analysed the epidemiologic distribution and relation with other diseases. In 437 patietns, nontraumatic femoral head necrosis(NTFHN) were 340 patients(77.8%) and traumatic femoral head necrosis(TFHN) were 97 patients(22.2%). The male was more affected in ratio of 4:1, especially higher in NTFH about 4.6:1. The peak incidence of age distribution was 4th and 5th decades. The most frequent probable etiologic factors in NTFN was idiopathic(137 patients, 40.3%) and followed by alcoholic(124 patients, 36.5%), steroid induced(53 patients, 15.6%). The cases of bilateral involvement in NTFHN were 182 patient(53.5%). The steroid induced cases(69.8%) were higher than other cases in bilaterality. Liver disease was the most frequent associated disease and it was followed by diabetes mellitus and renal disease. In steroid induced cases, the underlying causes of its medication were nephrotic syndrome(12 patients), arthralgia(8 patients) and dermatologic diseases(7 patients), etc. The abnormal findings of selologic studies in NTFN were hyperlipidemia(28.1%), hyperuricemia (17.0%) and increased transmainase(18.5%) and there was contact relationship between hyperilipidemia and increased transmainase. Marked declination of Harris score was found between stage II and stage III in the course progression of NTFHN. The annual incidence of femoral head osteoncerosis increased gradually

Objective: To investigate the relationship between hemoglobin and serum uric acid in adults with various glucose metabolism status. Methods: The demographic data and biochemical indicators of the adult population who had received physical examination in the Second Medical Center of the PLA General Hospital from January 2018 to December 2021 were collected. The subjects were divided into two groups according to the level of serum uric acid: the normal uric acid group and the hyperuricemia group. The relationship between hemoglobin (stratified into four levels of Q₁ to Q₄ by the quartile) and serum uric acid was quantified by using Pearson correlation and logistic regression analysis. The effects of age and glucose metabolism status on the relationship between hemoglobin and serum uric acid were analyzed. Results: A total of 33 183 adults were enrolled with age (50.6±10.0) years. The level of hemoglobin in the normal uric acid group (142.61±14.24) g/L was significantly lower than that in the hyperuricemia group [(151.79±11.24) g/L, P<0.001]. Univariate Pearson correlation analysis showed that hemoglobin was positively associated with serum uric acid (r=0.444, P<0.001). After adjusting for related confounding factors, multivariate logistic regression analysis showed that hemoglobin was associated with serum uric acid, and the OR values (95%CI) of hemoglobin Q₂ to Q₄ group were 1.29 (1.13-1.48), 1.42 (1.24-1.62) and 1.51 (1.32-1.72), respectively (P_trend<0.001) when compared with hemoglobin Q₁ group. Subgroup analysis and hierarchical interaction analysis suggested that with the increase of hemoglobin, the serum uric acid in the age<60 years subgroup, normal glucose subgroup and prediabetes subgroup increased gradually (P_trend<0.05 and P_interaction<0.001). Conclusion: The association between hemoglobin and serum uric acid in adults is affected by age and glucose metabolism status.

Uric acid is the end-product of purine metabolism. It has been widely accepted that the increase in the level of uric acid significantly raises the risks of gout, cardiovascular disease, and type 2 diabetes. The studies in recent years have shown that hyperuricemia is closed related to nonalcoholic fatty liver disease (NAFLD). This review summarizes the research advances in the association between hyperuricemia and NAFLD and related mechanisms based on the author's recent research findings.

OBJECTIVETo explore the epidemiological status and risk factors of hyperuricemia in rural area of the Three Gorges.

METHODSA cross-sectional survey was carried out in rural area of Yiling District, Yichang City, which was located north-west bank of Xiling Gorge in 2007. A standard structure questionnaire was used to collect demographic data, social-economic status and life-style features. Fasting venous blood was collected and serum uric acid (SUA) was determined. Hyperuricemia was defined as SUA levels ≥ 417 µ mol/L (70 mg/L) in men and ≥ 357 µmol/L (60 mg/L) in women. Multiple logistic regression analysis was used to analysed the risk factors of hyperuricemia.

RESULTSA total of 9354 participants aged 35 and above were included, 19.9% (1866/9354) participants were the Three Gorges migrants. Serum uric acid level in men was significantly higher than that in women [(285.1 ± 80.2) µmol/L vs. (210.3 ± 65.0) µmol/L,P < 0.01].Serum uric acid level increased significantly in both genders in proportion to increase of age, and was higher in men than in women in all age groups (all P < 0.01). The age-adjusted prevalence was significantly higher in men than in women (5.6% vs. 3.3%, P < 0.01), and was also higher in men aged 35-44 and aged 45-54 than in women (both P < 0.01). There was no significance in prevalence of hyperuricemia in both men and women aged 55-64 and aged ≥ 65. After adjusting age, gender, educational level, migration and occupation, the multiple logistic regression analysis showed that the prevalence of hyperuricemia was higher in alcohol drinking participants than that of non-alcohol drinking participants (OR = 2.06, 95%CI:1.59-2.67, P < 0.01), and in participants used to consume less green vegetables and fruits than in participants consuming more green vegetables and fruits (OR = 1.77, 95% CI:1.27-2.47, P < 0.01).

CONCLUSIONSThe prevalence of hyperuricemia is relatively low in rural area of the Three Gorges.Alcohol drinking and low intake of green vegetables and fruits are the risk factors of hyperuricemia in this population.

OBJECTIVETo investigate the relationship between metabolic syndrome and hyperuricemia.

METHODSA total of 2 374 subjects who received health examination in our hospital from Jan. 2004 to Dec. 2006 were enrolled in our study. Hyperuricemia is defined as >or=7 mg/dl (in men) or >or=6.0 mg/dl (in women). Metabolic syndrome was defined using AHA/NHLBI (American Heart Association/National Heart, Lung, and Blood Institute) criteria.

RESULTS(1) The overall prevalence of hyperuricemia was 13.10%. The condition was more common in men than in women (19.07% vs 3.42%). (2) Among men, uric acid concentration is statistically significantly positively correlated with waist circumference, blood pressure, and triglyceride. Uric acid is negatively correlated with serum high-density lipoprotein-cholesterol (HDL-C). Uric acid concentration is most strongly correlated with serum triglyceride (r=0.379) and waist circumference (r=0.297). Among women, statistically significant positive correlations were noted for the serum uric acid concentrations with waist circumference, triglyceride and fasting plasma glucose. Serum triglyceride (r=0.329) and waist circumference (r=0.234) are most strongly correlated with uric acid concentrations. (3) Men with hyperuricemia had a 1.634-fold increased risk of metabolic syndrome as compared with those without hyperuricemia [odds ratio (OR)=1.634, P=0.000]. Women with hyperuricemia had a 1.626-fold increased risk of metabolic syndrome (OR=1.626, P=0.000) as compared with those without hyperuricemia.

CONCLUSIONHyperuricemia is prevalent among Chinese population. Additionally, serum uric acid is positively associated with metabolic syndrome.
