Abstract

Temporary failure of red cell production has been well documented in hematologically normal persons, usually in association with infection, allergy, or a toxin.1,2 The brief duration of these episodes (seven to 14 days) in comparison to the relatively long life span of the normal erythrocyte (120 days) results in only a mild, transient, and usually unimportant drop in hemoglobin concentration. The same temporary failure in a patient with a congenital hemolytic anemia, on the other hand, is a dramatic event. In sickle cell disease, where the mean red cell life span has been estimated to range from 6 to 21.5 days 3,4 the same "aplastic" episode can result in a precipitous fall in hemoglobin to as low as half the steady state level over a two to seven day period. Thus a child who has maintained his hemoglobin at 6 gm% by a continuous brisk reticulocytosis may present with
