Serum urate in subjects with hypercalcaemic hyperparathyroidism

Abstract

A positive correlation was found between serum urate and elevated serum calcium in patients with hypercalcaemic primary hyperparathyroidism. No such correlation was detected in normocalcaemic controls, matched with respect to age and sex. Neither was such a correlation confirmed either in subjects with normalized serum calcium levels after extirpation of parathyroid adenomata, or in subjects with hypercalcaemia due to other conditions than primary hyperparathyroidism, such as various malignancies, sarcoidosis and hyperthyroidism. The positive correlation between elevated serum calcium and serum urate (within normal limits) in subjects with hypercalcaemic hyperparathyroidism is suggested in subjects with hypercalcaemic hyperparathyroidism is suggested to be a clue to the explanation of an association between hyperparathyroidism and urate retention.
