Abstract
Serum urate levels were studied in 18 patients with primary hyperparathyroidism (pHPT) and in 36 controls (group 2) matched for age, sex, nationality and blood pressure. These two groups were compared with general surgical inpatients (group 3). The prevalence of hyperuricemia was markedly higher in the pHPT patient group (especially for men) than in the other two groups [44,17 and 9%, respectively; p < 0.05 and < 0.001]. The prevalence of hypertension was markedly higher in the pHPT patient group (66.7%) than in the surgical inpatients [15%; p < 0.0001]. Five of the 9 male patients had both hypertension and hyperuricemia, the pathogenesis of which may be related to the action of hypercalcemia on renal functions. As the prevalence of hypertension and hyperuricemia were markedly higher than previously noted, it is suggested that more attention should be paid to blood pressure, serum urate and renal function in patients with primary hyperparathyroidism, in order to improve diagnosis and therapy.
