Vitamin B6 requirements in chronic renal failure

According to our results the long-term daily oral supplementation of 6 mg vitamin B₆ was sufficient for prevention of vitamin B₆ deficiency in chronic renal failure, regular dialysis treatment and CAPD groups of patients. Haemodialysis and charcoal haemoperfusion have led to non-significant decrease of erythrocyte vitamin B₆. A favourable effect was found of daily oral administration of 50 mg pyridoxine on electrophoretic mobility of peripheral blood lymphocytes and cellular immunity.
