Bone Abstracts

The analysis of intact parathyroid hormone (PTH) (PTH1–84) is useful in the diagnosis of hyper- and hypocalcaemia, hyperparathyroidism, and in the prevention of bone mineral disorders in renal patients. However, the analysis is complicated by the presence of PTH fragments. These are especially prone to accumulation in renal failure, and cross-react differently with different immunoassays, including the most recent, third-generation immunoassays. As such, large variability...

Objectives: We recently demonstrated that cow’s milk allergic infants who received an amino acid-based formula (AAF) for 16 weeks as oral feeding had adequate mineral status (1). One factor that may negatively affect mineral solubility and bioavailability and hence mineral status, is high gastric pH (2), but data on this in infants are lacking. Therefore, the present study evaluates serum concentrations of phosphorus, calcium and magnesium in a subgroup of infants on AAF ...
