Effect af Vitamin D Treatment in Primary Hyperparathyroidism - Full Text View

Sponsor:	University of Aarhus
Information provided by:	University of Aarhus
ClinicalTrials.gov Identifier:	NCT00674154

Purpose

The primary aim of the study is to assess whether 6-months of vitamin D supplements prior to surgery decreases the risk of postoperative hypocalcaemia in patients with PHPT. Secondary endpoints include effects of vitamin D supplements on bone turnover, BMD, quality of life, overall well-being, and muscle function.
