[Vitamin B6-deficiency and -substitution in chronic uremia (author's transl)]

In patients with chronic renal failure on potatoe-egg-diet (0.4 g protein/kg body weight) an alimentary vitamin B6-deficiency occurs, which can be overcome by 20 mg vitamin B6/day. Chronic hemodialysis causes a vitamin B6 loss which amounts to a quantity similar to the daily urinary excretion in normal persons. No hints for an inhibition of the synthesis of pyridoxal phosphate could be found.
