AB  - Objective. To systematically review available literature on treatment of hyperuricemia (HU) as a measure of preventing gouty arthritis, renal disease, or cardiovascular events in asymptomatic patients. Methods. A systematic literature search was conducted in the Cochrane Library, Medline, Embase, clinical trials registries of the World Health Organization and the US National Institutes of Health, and abstracts from American College of Rheumatology/European League Against Rheumatism meetings, for interventional studies involving adults with no history of gouty arthritis, who were treated for HU. Outcomes of interest included gouty arthritis, renal disease (i.e., renal insufficiency, urate nephropathy, nephrolithiasis), and cardiovascular events (i.e., myocardial infarction, heart failure, ischemic stroke). Results. A total of 3 studies met the inclusion criteria, 2 studies assessing the prevention of renal disease and 1 study evaluating the potential for delaying progression of preexisting renal disease. In hyperuricemic patients without renal disease, treatment resulted in increased estimated glomerular filtration rate. In hyperuricemic patients with preexisting renal disease, treatment resulted in no significant elevation of serum creatinine over a 1-year followup. However, differences in renal function between the treatment and no-treatment groups were not statistically significant in any of the identified studies. Conclusion. Very limited data are available on the treatment of HU in asymptomatic patients. There is currently insufficient empiric evidence to suggest that lowering serum uric acid level in asymptomatic patients with HU can prevent gouty arthritis, renal disease, or cardiovascular events.
