BK Virus Associated Late Onset Haemorrhagic Cystitis After Allogeneic Peripheral Blood Stem Cell Transplant

Natasha Ali et al. Indian J Hematol Blood Transfus. 2011 Sep.

Abstract

Haemorrhagic cystitis (HC) after allogeneic stem cell transplant is a clinical disorder with multiple etiologies. There is an inflammation of the bladder mucosa leading to painful haematuria. Early onset HC is mainly attributed to conditioning chemotherapy consisting of cyclophosphamide. Late onset HC is now being related to reactivation of latent polyoma BK virus (BKV). We describe the case of a 37 year old male with acute myeloid leukemia presenting with haematuria after allogeneic stem cell transplant.

Keywords: BK virus; Decoy cell; Stem cell transplant.
