Plasma exchanges do not increase red blood cell transfusion efficiency in severe autoimmune hemolytic anemia: a retrospective case-control study.

Severe autoimmune hemolytic anemia (AIHA) can cause life-threatening hemolysis requiring red blood cell transfusions (RBT). The efficiency of RBT could be improved with the use of plasma exchanges (PEx) before RBT. The objective of this study was to assess the effectiveness of PEx in severe AIHA of adults.
