title: The erythrocyte protoporphyrin in chronic renal failure.
abstract: The erythrocyte protoporphyrin concentration in 63 patients suffering from chronic renal failure was estimated and found to be significantly decreased when compared to healthy subjects. There was a negative correlation between the decrease of the erythrocyte protoporphyrin and the blood urea and haematocrit. Following haemodialysis the concentration of erythrocyte protoporphyrin was reduced but not significantly so. It is proposed that uraemia or insufficiency of erythropoietin could affect erythroblasts and young red cells impairing haem synthesis.
