title: CMV reactivation induced BK virus-associated late onset hemorrhagic cystitis after peripheral blood stem cell transplantation.
abstract: Hemorrhagic cystitis (HC) is a known complication of stem cell transplantation. In contrast to early-onset HC that is usually attributed to cyclophosphamide and occurs within a few days of infusion, late onset HC is associated with viral infection. In recent years BK virus has emerged as an important causative agent. We describe two patients who developed late onset HC (38 and 92 days post transplant) associated with BK viruria concomitant with CMV reactivation and suggest a possible role of CMV in the process of BK virus DNA replication.
