We report a haemodialysis patient with severe secondary hyperparathyroidism, in whom abnormally higher whole PTH levels than intact PTH levels were normalized during cinacalcet therapy. Moreover, we observed a marked reduction in parathyroid gland vascularity during this treatment. Our findings suggested that increased sensitivity of the parathyroid calcium sensing receptor by calcimimetics may modulate the secretion or truncation of N-PTH or other PTH molecules that can be detected by the whole PTH assay but not by the intact PTH assays. | | Language | ENG | | Pub Type(s) | JOURNAL ARTICLE
