Successful unrelated bone marrow transplantation for a human immunodeficiency virus type-1-seropositive acute myelogenous leukemia patient following HAART

The availability of highly active anti-retroviral therapy (HAART) has greatly improved the outcome of human immunodeficiency virus type-1 (HIV-1) infection and disease. We report here on a case of an HIV-1-seropositive patient with acute myelogenous leukemia who underwent a successful allogeneic unrelated bone marrow transplantation following HAART. A 40-year-old Japanese HIV-seropositive man underwent allogeneic unrelated bone marrow transplantation using a myeloablative pretransplant-conditioning regimen. Neutrophil engraftment occurred on day +18, and donor chimerism was achieved on day +27. During pre- and post- transplantation, the HAART was not interrupted. Over 1 year after transplantation, the patient is alive and in continuous complete remission with undetectable levels of HIV-1 RNA. HAART can lead to a successful hematopoietic stem cell transplantation without severe opportunistic infections.
