Adenovirus-associated hemorrhagic cystitis treated with intravenous ribavirin.

Adenovirus hemorrhagic cystitis following bone marrow transplantation occurs in 2 to 16% of the patients. While usually self-limiting, this disease can cause significant morbidity and even mortality in the immunocompromised patient. Risk factors include graft versus host disease and pre-transplant seropositivity to adenovirus. Standard treatment of this disorder consists of hydration, diuresis and analgesics. Failure of these measures leads to multiple blood transfusions, severe patient morbidity and possible death. When conservative therapy is unsuccessful, there is no proved standard of care. We recently used ribavirin, a broad-spectrum antiviral agent against adenovirus infection in vitro, to treat refractory adenovirus hemorrhagic cystitis after bone marrow transplantation. The hematuria and urinary symptomatology resolved without demonstrable side effects. We present ribavirin as a therapeutic alternative when conservative treatment for adenovirus hemorrhagic cystitis fails.
