Hyperparathyroidism Clinical Trial
Official title:
Serum Calcium to Phosphorous (Ca/P) Ratio in the Diagnosis of Ca-P Metabolism Disorders: a Multicentre Study
Primary hyperparathyroidism (PHPT) and Hypoparathyroidism (HP) are two of the most frequent disorder of Calcium-Phosphorus (Ca-P) metabolism. The Ca/P ratio is an accurate tool to differentiate patients with PHPT from healthy subjects, according to a previous single-centre study. The reliability of this index is based on the fact that serum Ca and P are inversely related together either in healthy subjects or in patients with PHPT and HP.
The aim of this study is to investigate the accuracy and diagnostic value of Ca/P ratio in the diagnosis of primary hyperparathyroidism and hypoparathyroidism. The definition of a valid cut-off of serum Ca/P ratio for patients with these disorders will be of help especially in those patients with apparently normal biochemical profile, but suggestive for primary hyperparathyroidism and hypoparathyroidism. ;
