Successful Treatment of BK Virus Hemorrhagic Cystitis (HC) Post Allogenic Hematopoietic Stem Cell Transplantation with Low Dose Cidofovir.

BK virus (BKV) hemorrhagic cystitis (HC) is a serious cause of morbidity and mortality after allogeneic hematopoietic SCT (allo-HSCT) in patients with hematological malignancies. Around half of allogenic HSCT patients present with BKV viruria at some point after HSCT; about 5-40% of these patients subsequently develop active HC. Supportive care including bladder irrigation, blood transfusions and symptomatic pain management remains the mainstay of therapy; the acyclic nucleoside analogue cidofovir is currently the front-line drug for BKV-HC treatment. Here we report the first case of severe hemorrhagic cystitis from India who was successfully treated with low dose cidofovir therapy.
