Serum-ionized calcium in mexican protein-energy malnourished children.


BACKGROUND Hypocalcemia occurring in children with severe primary protein-energy malnutrition (PEM) has previously been shown to merely reflect a reduction in the protein-bound fraction of serum calcium. On the other hand, ultrafilterable, i.e., nonprotein bound calcium (Ca(U)), remains unaffected. The aim of the present investigation was to test the… (More)
