The donor's CMV CTL cells will be thawed and injected into the patients intravenous line for a period of 10 minutes after the patient received Benadryl and Tylenol. The patient will receive the dose of CMV CTL cells on or after day 30 following their transplant if they agree and are well enough. We will not give antiviral medications during this study but we will monitor the CMV levels weekly for at least 30 days after the transplant. If after the initial dose of CMV CTL cells the patient develops a viral infection, then they may be eligible to receive one additional injection of CTLs at the same dose as the first injection. If the CMV levels in the blood continue to rise after the dose of T cells then the patient will receive treatment with Ganciclovir, Foscarnet, or Cidofuvir.
