Ascorbic acid therapy for the relief of bone pain in Paget's disease

Sixteen patients with painful Paget's disease of the bone were treated with high doses of ascorbic acid. Of these patients, 8 experienced lessening of pain within a period of 5 to 7 days after commencing the vitamin therapy. In 3 of these patients pain was completely abolished. Subsequent treatment with calcitonin caused improvement in most cases. There was little change in plasma alkaline phosphatase levels but the excretion of hydroxyproline was elevated following administration of the vitamin. The highest excretions were found in those patients who experienced complete relief of pain. In patients treated with calcitonin alone, the excretion of hydroxyproline was reduced and urinary levels of ascorbic acid dropped in parallel. It seems clear that ascorbic acid and calcitonin have different effects upon bone metabolism.
