Abstract
No data on the pharmacological treatment of normocalcemic hyperparathyroidism NPHPT are available We treated 30 NPHPT postmenopausal women with alendronate/cholecalciferol treated group or vitamin D alone control group Over 1 year bone mineral density BMD increased significantly in treated group but not in control group Both treatments did not affect serum or urinary calciumNormocalcemic primary hyperparathyroidism NPHPT is defined by normal serum calcium and consistently elevated PTH levels after ruling out the causes of secondary hyperparathyroidism It is likely that subjects with NPHPT may develop kidney and bone disease As no data on the pharmacological treatment of NPHPT are available we aimed to investigate the effects of alendronate and cholecalciferol on both BMD and bone biochemical markers in postmenopausal women with NPHPT Safety of vitamin D was evaluated as secondary endpointThe study was a prospective open label randomized trial comparing 15 postmenopausal women with NPHPT PMWNPHPT treated with oral alendronate plus cholecalciferol treated group and 15 PMWNPHPT treated only with cholecalciferol control group Blood samples were obtained at baseline and after 3 6 and 12 months Bone turnover markers BTM were measured at baseline 3 and 6 months respectively BMD was assessed at baseline and after 12 monthsAfter 1 year of treatment BMD increased significantly at the lumbar femoral neck and hip level in the treated group but not in the control group p = 0001 No differences were found between or within groups in serum calcium PTH and urinary calcium levels BTM significantly decreased in the treated group but not in the control group at 3 and 6 months p 0001 respectively No cases of hypercalcemia or hypercalciuria were detected during the study
