Abstract: Endocrinology, Volume 159, Issue 7, July 2018, Pages 2741–2758In brief: Eldecalcitol, a long acting active vitamin D3 analogue with lower affinity for vitamin D receptor and resistance to inactivation by vitamin D 24-hydroxylase, causes FGF23 resistance. This leads to complete restoration of renal phosphate transport and NaPi-2a protein levels and improves ra...
