Cinacalcet as rescue therapy for refractory hyperparathyroidism in young children with advanced chronic kidney disease

Background Studies in the use of the calcimimetic, cinacalcet, in pediatric chronic kidney disease (CKD) are few and limited to older children with secondary hyperparathyroidism (sHPT), a major morbid complication contributing to poor growth, bone deformities, and cardiovascular disease. Our objectives were to determine a safe and effective dosing regimen of cinacalcet in the treatment of infants and young children with sHPT that was refractory to standard care and to examine their growth during treatment.
