Chronic idiopathic pure red cell aplasia: successful treatment during pregnancy and durable response to intravenous immunoglobulin.

A patient with chronic idiopathic pure red cell hypoplasia responded to intravenous immunoglobulin therapy. No other treatment was administered. During treatment, the patient was taken through two pregnancies without haematological problems. After 22 months of therapy, the intravenous immunoglobulin was discontinued; a durable remission was subsequently maintained. Intravenous immunoglobulin may be the treatment of choice for females of child-bearing potential.
