Rh (D) alloimmunization treated by double filtration plasmapheresis.

Here in this report a 31 year old pregnant woman with positive serum antiglobulin test against anti-D antierythrocyte antibodies who was treated succesfully with double filtration plasmapheresis (DFPP) is presented. The DFPP was started in the early stage of pregnancy together with intravenous immunoglobulin therapy and the antierythrocyte antibody titer of the patient was successfully maintained in a stable level below 1:64 dilution. She delivered successfully on the 30th week of gestation. The favorable outcome of this patient implies that DFPP is an effective and safe treatment modality in pregnant women with red cell alloimmunization.
