This study enrolled 122 patients including 63 women (51.6%). The mean age was 55.9 ± 10.6 years (range 30 to 74 years). Obesity weight was found in 38 cases (31.1%) of which 20?were men (33.9%) and 18 women (28.6%). Abdominal obesity was found in 104 cases (85.2%). The average serum uric acid in patients with obesity weight was 63.3 ± 18.9 mg/L vs 62.4 ± 14.2 mg/L for no-obese patients (p?= 0.63). The average serum potassium in obese patients was 4.06 ± 0.42 mEq/L vs 4.02 ± 0.46 mEq/L for no-obese (p?= 0.65). The average GFR was 73.4 ± 21.4 ml/L in obese patients vs 66.6 ± 22.6 ml/min in no-obese (p?= 0.03). The LVH was found in 81 cases (66.4%). The LVH was found in 65 (62.5%) obese patients vs?16 (88%) non-obese patients (OR = 4.8, 95% 1.04?-?22?p?= 0.02). Only abdominal?obesity has been correlated with left ventricular hypertrophy after multivariate analysis. Emphasis must be focused on public health actions for effective and appropriate measures against obesity and hypertension, whose prevalence is increasing in our region.展开更多

We used data for 108 Japanese men (45.3 ± 8.0 years) with a 1-year follow up. eGFR was defined by a new equation developed for Japan. eGFR was weakly correlated with serum uric acid levels (r = –0.287, p = 0.0026) at baseline. Subjects were given advice for dietary and life-style improvement. At the 1-year follow up, almost metabolic syndrome components were significantly improved. However, blood sugar and uric acid did not change and eGFR was significantly decreased. The changes in eGFR were weakly correlated with abdominal circum-ference (r = –0.249, p = 0.0094) and uric acid (r = –0.340, p = 0.0003). A decrease in serum uric acid levels may be associated with improving eGFR in Japanese men.展开更多

Methods The medical reports of 47 MS patients admitted to Peking Union Medical College Hospi- tal during 2008 and 2010 were reviewed. And 49 age- and gender-matched cerebral infarction patients were enrolled as control. The mean serum HA level of the MS patients was compared with that of the control group. The correlations between the HA levels and the clinical parameters including gender, disease duration, relapse rate, and disease disabilities as assessed by the Expanded Disability Status Scale score, were explored. Forty-one patients had CSF examinations. The correlations between the IdA levels and the CSF parameters reflecting inflammation and tissue damage, including CSF protein, white blood cell count, oligoclonal band, 24-hour IgG index, and myelin basic protein, were also investigated. Results The mean serum HA level in the MS patients was lower than that in the control group （247.75 ± 52.59 jamol/L vs. 277.94 ± 74.33 pmol/L, P=0.025） and inversely correlated with the relapse rate （P=0.049）. MS patients with lower serum UA levels tended to have higher white blood cell counts and myelin basic protein level. But there was no correlation between CSF protein levels （r=0.165, P=0.273）, white blood cell counts （r=-0.051, P=0.732）, IgG index （r =0. 045, P=0.802）, or myelin basic protein level （r =-0.248, P=0.145） and the serum UA level, respectively. Conclusion In MS patients, UA levels might partly reflect the extent of disability and inflammation.展开更多

The present study explores how these two factors have an association with the new incidence of CKD. Methods: Study design is a cohort study. A total of 14,485 participants were eligible for the cross-sectional analysis on UA levels and the prevalence of Mets. Among those individuals, 8,223 participants without CKD and 4,839 without Mets were eligible for the longitudinal analysis of the new incidence of CKD. Parameters monitored were body mass index, systolic and diastolic blood pressure, serum creatinine concentration, estimated glolerular filtration rate, lipid profiles, plasma glucose, HbA1c. The primary predictor was the level of UA and Mets to explain the newly-developed CKD. The observation period was 4 years. Results: In a cross-sectional analysis, higher UA levels were associated with the greater prevalence of Mets. In addition, UA levels were associated with the numbers of the Mets constituents in both genders. In a longitudinal analysis, higher UA levels were associated with the greater rate of CKD and the greater incidence of Mets. In addition, the incidence of CKD at year 4 was influenced by the presence of hyperuricemia, but not by that of the Mets. The odd ratio (OR) to predict the CKD incidence was 1.42 (95% confidence intervals (CI), 0.52 to 3.78) in the presence of Mets alone, 2.10 (95% CI, 1.36 to 3.23) in the presence of hyperuricemia alone, and 3.56 (95% CI, 1.55 to 8.21) in the presence of both. Conclusion: Hyperuricemia has a greater association with the incidence of CKD than Mets does. Hyperuricemia complicated by Mets is additionally detrimental.展开更多
