Filter by: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.
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.
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.
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.
