Abstract:
The frequency of hyperuricemia in 253 patients with essential hypertension (EH) was studied. The level of uric acid in serum and frequency of hyperuricemia were determined in patients divided according to sex and renin plasma activity (RPA). High values of uric acid in serum were found in a total of 69 patients (27.3%), of which there were 40 males (30.1%) and 29 females (24.2%). The highest values of uric acid were found in those with high RPA, but the difference was significant only in males (p < 0.05). No correlation was observed between the values of the uric acid in serum and RPA in none of the renin subgroups. On the basis of our study, it was not possible to explain the high values of uric acid in serum in patients with EH, especially in those with high plasma renin activity, as well as the role of renin-angiotensin-aldosterone system in the pathogenesis of hyperuricemia.
