title: Effect of fenofibrate on uric acid metabolism in Japanese hyperlipidemic patients.
abstract: Forty Type IIb or IV hyperlipidemic patients (serum triglyceride concentrations were higher than 150 mg/dl) were treated with fenofibrate (300 mg/day) for 12 weeks. Lipid profile and uric acid metabolism were evaluated before and after the treatment; the serum concentrations of total cholesterol and triglyceride respectively decreased from 224 +/- 41.9 mg/dl to 199 +/- 35.2 mg/dl and from 205 +/- 71.7 mg/dl to 134 +/- 67.5 mg/dl (p < 0.001). The uric acid concentrations in the serum also significantly decreased from 7.0 +/- 1.58 mg/dl to 5.2 +/- 1.57 mg/dl (p < 0.001). Fenofibrate treatment did not cause any change in the serum xanthine and hypoxanthine concentrations. Instead the urinary concentrations of uric acid decreased from 7.0 +/- 1.58 mg/dl to 5.2 +/- 1.57 mg/dl (p < 0.01), while the clearance ratio of uric acid and creatinin increased from 6.1 +/- 2.56 to 9.9 +/- 3.87 (p = 0.02) by the fenofibrate treatment. Fenofibrate decreases uric acid concentrations in the serum not as a result of inhibition of uric acid production but by increasing the urinary excretion of uric acid.
