Comparison of vitamin D and 25-hydroxy-vitamin-D in the therapy of primary biliary cirrhosis

Abstract

Skeletal demineralisation and low serum concentrations of 25-hydroxy-vitamin-D were observed in patients with primary biliary cirrhosis. Neither oral nor parenteral vitamin-D increased 25-hydroxy-vitamin-D in serum or prevented further skeletal demineralisation. In contrast, oral 25-hydroxy-vitamin-D increased serum-25-hydroxy-vitamin D concentrations in all patients, and bone mineral content either improved or stabilised in all but one, 25-hydroxy-vitamin-D may be the preferred form of vitamin-D therapy in primary biliary cirrhosis.
