Ascorbic acid is a metabolic precursor of oxalic acid. Because this compound accumulates during chronic renal insufficiency (1), the administration of ascorbic acid could cause a further increase of plasma oxalic acid levels in patients on chronic hemodialysis.Over a period of 4 weeks, nine patients on chronic hemodialysis (seven men, two women; mean age, 41 years) received 1 g of ascorbic acid intravenously after each dialysis session, or a total dose of 12 g for each patient. The clinical diagnosis...
