Urate-lowering therapy for asymptomatic hyperuricaemia: A need for caution

摘要

Objective: The observed associations of hyperuricaemia with hypertension, cardiovascular disease and kidney disease are receiving increasing interest. The potential role of urate-lowering therapy in the management of these "non-gout diseases" has been raised, and in some countries it is already recommended. However, there is no consistent definition of hyperuricaemia or asymptomatic hyperuricaemia, much remains unknown about the causal role of urate in these "non-gout diseases" and there is currently a lack of evidence about the effects of urate lowering on disease progression. In addition, there is potential for serious adverse effects associated with urate-lowering therapies with recent evidence suggesting that asymptomatic hyperuricaemia may be an independent risk factor for the potentially fatal allopurinol hypersensitivity syndrome.
