Background:
A 29-year-old man, who underwent allogeneic bone marrow transplantation (BMT) for acute non lymphoid leukemia (ANLL), presented with blood pancytopenia and mild hypoxemia on day +39, without signs of acute graft versus host disease (GVHD).
Methods And Results:
Cytomegalovirus (CMV) antigens were detected on WBCs and cells from bronchoalveolar lavage by immunofluorescence (IF) with specific murine monoclonal antibodies. Prompt treatment with Ganciclovir and high titer CMV immunoglobulins was followed by disappearance of the laboratory findings of CMV infection. Therapy was well tolerated and no side effects were recorded except for hematological depression that did not reverse after withdrawal of the therapy. The patient is relatively well on day + 210.
Conclusions:
Detection of CMV antigenemia appears to be a valuable tool for deciding whether to start CMV therapy with potentially toxic antiviral drugs in BMT patients in early engraftment, with or without overt signs of CMV infection.
