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.

Cytomegalovirus Disease

Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
