abstract: Serum carboxyterminal parathyroid hormone (PTH) concentration (homologous measurement of the 53-84 fragment and heterologous bovine measurement) has been measured and correlated with both clinical and radiological findings of secondary hyperparathyroidism (HPT), studied quantitatively according to a score published in literature, in 95 patients with chronic renal failure on maintenance hemodialysis. Mean serum PTH concentration (53.84) is statistically higher in patients with severe clinical and radiological evaluation of HPT than in patients with moderate or slight manifestations of HPT (M +/- DS: 515.8 +/- 243.7 pg/ml VS 271.3 +/- 166.1 pg/ml p less than 0.001). However, even with high serum concentration, serum PTH level does not allow to predict HPT severity, suggesting a retention of PTH fragments in serum without biologic activity probably.
