Vitamin D Metabolism in Patients With Endocrine Disorders

Diabetes Mellitus, Type 1 Clinical Trial

Official title:
Prospective Non-randomised Controlled Study of Vitamin D Metabolism in Patients With Endocrine Disorders (Acromegaly, Cushing's Disease, Primary Hyperparathyroidism, Diabetes Mellitus Type 1) Treated With Cholecalciferol Bolus Dose

Clinical Trial 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.
