Behavior of Bone Mineral Metabolism in Renal Posttransplantation Patients with Severe Hyperparathyroidism.

Background: Secondary hyperparathyroidism usually improves after renal transplantation. When it becomes persistent, it is associated with deleterious effects on the graft, bone demineralization, fractures, calcifications, and cardiovascular events. In this study we describe the development of cases of severe hyperparathyroidism occurring after renal transplantation.
