Changes in serum transferrin and iron concentrations in humans suffering from malaria with parasitaemia.
Sera from non-malarial (control) and Plasmodium falciparum-infected (malaria) subjects were assayed for transferrin and iron. The mean serum transferrin concentration in the malaria sera was found to be elevated by 44% above the control value. The mean serum iron was also raised in the malaria sera, but the increase (19%) was found to be well below that of transferrin. The mean saturation of serum transferrin with iron fell from 42 +/- 17% in the control group to 37 +/- 9% in the malaria group. It is suggested that the increase in transferrin concentration in the sera of malaria subjects probably resulted from an increase in the rate of transferrin synthesis, perhaps in response to the raised serum iron and/or the hypoxia which is known to be associated with malaria infection.
