Calcitriol pulse therapy and histology of parathyroid glands in hemodialysis patients.

Background: Calcitriol pulse therapy (CPT) is considered the most appropriate treatment of secondary hyperparathyroidism (sHPTH). This treatment inhibits parathyroid hormone (PTH) synthesis and secretion, suppresses parathyroid cell proliferation and controls parathyroid gland growth. However, not much is known about the effect of such therapy on parathyroid morphology.
