Hemolytic anemia after fludarabine therapy for chronic lymphocytic leukemia.

Abstract

HA associated with fludarabine therapy appears to be uncommon, but it can be severe and fatal, especially if a patient is re-treated with this drug after a previous episode of HA. The mechanism of this toxicity is unknown, but it may be caused by the release of a suppressed auto-antibody to a native red cell antigen.
