BACKGROUND Renal failure results in decreased calcitriol production, a key factor in the development of secondary hyperparathyroidism. Phosphorus accumulation and high parathyroid hormone (PTH) levels, both inherent to renal failure, have different effects on calcitriol production; moreover, dietary calcium loading may have a separate inhibitory effect on calcitriol production. This study was d...
