Background: Related studies have demonstrated a relationship of elevated serum uric levels with a decline in kidney function. However, limited evidence exists in a Southeast Asian community-based population. Objective: The study aimed to examine the relationship between serum uric acid levels and impaired renal function. Methods: A prospective cohort study was conducted in the Thai army health checkup population between July 1, 2006 and December 31, 2012. Inclusion criteria included age older than 20 years and baseline estimated glomerular filtration rate (eGFR) over 60 mL/min/1.73 m(2). Cox regression analysis was used to evaluate the association between incidence of impaired renal function and baseline serum uric acid quartiles. Impaired renal function was defined as eGFR Results: A total of 9,534 participants (7,474 men and 2,060 women) were enrolled. Cox regression analysis revealed a significant association of serum uric acid level with impaired renal function in the whole population as the unadjusted hazard ratio (HR) (95% CI) of impaired renal function in second, third, and fourth quartiles were 2.1 (1.39, 3.17), 2.39 (1.6, 3.59), and 3.94 (2.71, 5.74), respectively, when compared with serum uric acid in the first quartile, respectively. After adjusting in 2 models, the HR still significantly persisted with similar magnitudes in all quartiles. Higher incidences of impaired renal function were observed among males than among females in all quartiles. Kaplan-Meier curve showed better renal survival rate in the lower quartile groups. Linear regression analysis showed that eGFR negatively correlated with serum uric acid (r = -0.213, p < 0.001). Conclusion: Our study suggests that an independent association exists of serum uric acid levels with the incidence of impaired renal function and renal progression in the Southeast Asian community-based population.

Background Bariatric surgery reduces incidence of albuminuria and end-stage renal disease in patients with obesity. Effects of bariatric surgery on long-term remission and progression of pre-existing obesity-related renal damage are mainly unexplored. Here we investigate the long-term effects of bariatric surgery compared with conventional obesity care on remission and progression of albuminuria. Methods 4047 patients were included in the Swedish Obese Subjects study. Inclusion criteria were age 37-60 years, BMI >= 34 kg/m(2) in men and BMI >= 38 kg/m(2) in women. Our analysis comprised 803 patients (19.8% of total population, 357 control, 446 surgery) with pre-existing albuminuria including 693 patients (312 control, 381 surgery) with microalbuminuria, and 110 patients (45 control, 65 surgery) with macroalbuminuria. Surgery patients were treated with banding, vertical banded gastroplasty, or gastric bypass. Control patients received conventional obesity care. Results Total urinary albumin excretion was 36.5% lower in all patients with albuminuria after 15 years, 44.5% lower in patients with microalbuminuria after 15 years, and 27.8% lower in patients with macroalbuminuria after 2 years following bariatric surgery compared with conventional care. In surgery patients with microalbuminuria, remission to normoalbuminuria was higher (OR, 5.9, 2.2, 3.2, p < 0.001) and progression to macroalbuminuria was lower (OR, 0.28, 0.26, 0.25, p <= 0.02) at 2, 10, and 15 years, respectively, compared with control patients. In surgery patients with macroalbuminuria remission to normo- or microalbuminuria was higher (OR, 3.67, p = 0.003) after 2 years. No differences between surgery and control patients with macroalbuminuria were observed after 10 and 15 years. Surgery slowed progression of eGFR decline after 2 years in patients with microalbuminuria and macroalbuminuria (treatment effect: 1.0 ml/min/1.73 m(2)/year, p = 0.001 and 1.4 ml/min/1.73 m(2)/year, p = 0.047, respectively). Conclusion Bariatric surgery had better effects than conventional obesity care on remission of albuminuria and prevention of eGFR decline, indicating that patients with obesity-related renal damage benefit from bariatric surgery.
