NCT ID: NCT05141838 Recruiting - Osteoporosis Clinical Trials

Vitamin D Status and Bone Metabolism Status in Children With Congenital Epidermolysis Bullosa

Start date: November 21, 2020
Phase: Phase 4
Study type: Interventional

This retrospective prospective study is aimed at studying the level of vitamin D supply and identifying markers of bone tissue remodeling in order to develop approaches to the prevention of osteopenia and osteoporosis in children with congenital epidermolysis bullosa.

NCT ID: NCT04019379 Active, not recruiting - Clinical trials for Chronic Kidney Diseases

Calcium and Phosphorus Whole-Body Balance and Kinetics in Patients With Moderate Chronic Kidney Disease

Start date: August 31, 2020
Phase: N/A
Study type: Interventional

This pilot study aims to develop a method for simultaneous whole-body calcium and phosphorus balance and full kinetic modeling of both ions in patients with chronic kidney disease.

NCT ID: NCT03747029 Completed - Hyperparathyroidism Clinical Trials

Serum Calcium to Phosphorous (Ca/P) Ratio in the Diagnosis of Ca-P Metabolism Disorders: a Multicentre Study

Start date: November 28, 2017
Phase:
Study type: Observational

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.

NCT ID: NCT03603444 Completed - Clinical trials for Phosphorus and Calcium Disorders

Reliability of Serum Calcium to Phosphorus (Ca/P) Ratio as an Accurate and Inexpensive Tool to Define Disorders of Ca-P Metabolism

Start date: January 1, 2011
Phase:
Study type: Observational

BACKGROUND: Primary hyperparathyroidism (PHPT) is the third most common endocrine disorder. The Ca/P ratio is an accurate tool to differentiate patients with PHPT (>3.5 if Ca and P are expressed in mg/dl) from healthy subjects. The reliability of this index is based on the fact that serum Ca and P are inversely related together. However, other disorders of the Ca-P metabolism, such as hypophosphoremia (HypoP) not related to PHPT, might also impair the Ca/P ratio. OBJECTIVE: To validate the accuracy of Ca/P ratio in the diagnosis of Ca-P metabolism disorders, including also patients with documented HypoP not related to PHPT. METHODS: A single-center, retrospective, case-control study will be carried out. Biochemical measurements will include parathormone (PTH), vitamin D, serum Ca and P, serum albumin and creatinine.
