<unk>  is associated with profound lymphopenia, and as a consequence, increases the risk of opportunistic infections. People who have been treated with<unk>  will usually be asked to take co-trimoxazole or to use monthly nebulised pentamidine to prevent Pneumocystis jiroveci pneumonia.

For this reason, all patients who have ever received<unk>  should only be given irradiated blood components.<unk>  causes anemia, thrombocytopenia and neutropenia, requiring regular blood count monitoring. Some patients require blood and platelet transfusion, or G-CSF injections to boost neutrophil counts.<unk>  is associated with the development of severe autoimmune hemolytic anemia in a proportion of patients. Difficulties are often encountered when harvesting peripheral blood stem cells from patients previously treated with<unk> .
