Vitamin D Metabolism in Patients With Endocrine Disorders

Summary

This prospective controlled interventional study aims to reveal the diversity of vitamin D metabolism in patients with certain endocrine disorders (Cushing's disease, acromegaly, primary hyperparathyroidism, diabetes mellitus type 1) compared to healthy adults. All patients will receive a single dose (150,000 IU) of cholecalciferol aqueous solution orally. Laboratory assessments including serum vitamin D metabolites (25(OH)D3, 25(OH)D2, 1,25(OH)2D3, 3-epi-25(OH)D3, 24,25(OH)2D3 and D3), free 25(OH)D, vitamin D-binding protein (DBP) and parathyroid hormone (PTH) as well as serum and urine biochemical parameters will be performed before the intake and on Days 1, 3 and 7 after the administration.
