We have observed hypercalcemia during thiazide therapy in three uremic patients with clinically overt secondary hyperparathyroidism; serum calcium levels fell upon cessation of thiazide therapy. To further evaluate this phenomenon, studies were undertaken in 14 uremic patients undergoing maintenance hemodialysis. Hydrochlorothiazide, 200 mg/day, was given orally for 2 to 4 weeks; calcium was measured in predialysis and postdialysis blood samples, obtained twice weekly, before (control period), during, and after thiazide therapy. Serum calcium rose to levels above the... This content is PDF only. To continue reading please click on the PDF icon. Author, Article, and Disclosure InformationAffiliations: Los Angeles, Calif.
