title: [Hyperuricemia - more than gout : Impact on cardiovascular risk and renal insufficiency].
abstract: BACKGROUND
  Hyperuricemia is not only associated with gout but also with hypertension, atherosclerosis and chronic kidney disease (CKD); however, in cases of disproportionally high serum uric acid levels without symptoms of gout and slowly progressive chronic kidney failure especially in young people, a genetic cause of hyperuricemia needs to be considered.
  The results of experimental studies suggest that hyperuricemia can be a pathophysiologically relevant cardiovascular risk factor. In animal studies hyperuricemia leads to oxidative stress and vascular dysfunction and chronically elevated uric acid levels can result in structural changes of the vessel wall. Epidemiological data show a connection between hyperuricemia and hypertension and uric acid lowering therapy has been shown to lower arterial blood pressure. In CKD, uric acid increases in parallel with the decline in GFR and an increase in proteinuria. Several ongoing prospective clinical trials will clarify if pharmacological lowering of uric acid will translate into reduction of relevant cardiovascular and renal endpoints.
  
  
  METHODS
  The treatment of gout and the medicinal prophylaxis of further gout attacks depend on the comorbidities and especially CKD.
