Hyperuricemia
Encyclopedia : H : HY : HYP : Hyperuricemia
Hyperuricemia is the presence of high levels of uric acid in the blood. The upper end of the normal range is 530 micromol/L (6 mg/dL) for women and and 619 micromol/L (7 mg/dL) for men. [link] Hyperuricemia is caused either by accelated generation of uric acid through purine metabolism or by impaired excretion in the kidney, or by high levels of fructose in the diet.[link][link]
Humans lack urate oxidase, an enzyme which degrades uric acid. Increased levels predispose for gout and (if very high) renal failure. Apart from normal variation (with a genetic component), tumor lysis syndrome produces extreme levels of uric acid, mainly leading to renal failure.
