Three patient categories were studied, severe malarial anaemia (SA), cerebral malaria (CM) and uncomplicated malaria (UM). Red cell distribution width (RDW) was used as a surrogate marker of release of young erythrocytes and reticulocytes. Initially RDW was low in all patients in spite of markedly increased concentrations of erythropoietin (EPO). 3 d after institution of treatment and coinciding with parasite clearance RDW increased dramatically, reaching the highest levels 1-2 weeks later. Although severe anaemia was corrected by blood transfusion during the first 3 d of treatment, the peak RDW correlated significantly with the initial EPO levels. This suggests that Plasmodium falciparum infection causes a rapidly reversible suppression of the bone marrow response to EPO. Furthermore, the inhibition of bone marrow response was a general finding irrespective of initial haemoglobin levels suggesting that the severity of anaemia depends upon the degree of peripheral erythrocyte destruction in patients with suppressed bone marrow response to EPO.",
