Hyperuricemia
In medicine, hyperuricemia is "excessive uric acid or urate in blood as defined by its solubility in plasma at 37 degrees C; greater than 0.42mmol per liter (7.0mg/dL) in men or 0.36mmol per liter (6.0mg/dL) in women. This condition is caused by overproduction of uric acid or impaired renal clearance. Hyperuricemia can be acquired, drug-induced or genetically determined (Lesch-Nyhan Syndrome). It is associated with hypertension and gout."[1][2] Niacin[3] can increase serum uric acid levels.
Hyperuricemia may[4][5] or may not[6] be associated with vascular disease[2] and chronic kidney disease[7][2] and metabolic syndrome[8]. If hyperuricemia is associated with vascular disease, a meta-analysis suggests that the strength of association is unlikely to be large enough for the presence of hyperuricemia to help in the prediction of vascular disease.[9]
Randomized controlled trials suggests that treatment of hyperuricemia may:
- Slow the progression of chronic kidney disease[7]
- Reduce hypertension[10]
- Reduce angina pectoris.[11]
