Abstract

The influence of diabetic treatment regimens on vitamin D metabolism and on bone mineral content has been explored in 41 elderly patients with normal renal and hepatic functions. The data obtained suggest that oral treatment with hypoglycemic compounds exerts a negative influence on vitamin D metabolism. It is possible that the reduction of 25-OH-hydroxy-vitamin D levels depends on a high conversion rate to the active 1,25-dihydroxy-vitamin D, as a consequence of parathormone-stimulated increase of 1-alpha-hydroxylase activity. On the other hand, no differences in bone mineral densities were observed in correlation with the diabetic treatment regimens. Therefore, oral treatment with hypoglycemic compounds can only be associated with an accelerated vitamin D metabolism.
