Is aplastic osteodystrophy a disease of malnutrition?

Adynamic bone disease is emerging as a major type of renal osteodystrophy in chronic dialysis patients. Relative hypoparathyroidism is one of the important abnormalities underlying this disease. Recently, several reports have suggested that hypoparathyroidism reflects, at least in part, a state of malnutrition and contributes to the poor prognosis of patients on hemodialysis and chronic ambulatory peritoneal dialysis. Such a risk of survival may result not only from the malnutritional state, but also from unknown mechanisms resulting from parathyroid hormone (PTH) deficiency, or from other abnormalities that suppress PTH secretion. Another major abnormality underlying adynamic bone disease is the skeletal resistance to PTH in patients with uremia. Owing to the recent research on bone turnover at the molecular level, several new mechanisms for this abnormality have been elucidated. Correction of this 'skeletal resistance to PTH' will lead to the optimal management of parathyroid function and bone turnover in the future.
