Adenovirus‐associated hemorrhagic cystitis in a pediatric renal transplant recipient

Adenovirus infection has been associated with the development of hemorrhagic cystitis in bone marrow transplant recipients. However, limited information exists regarding adenovirus-associated hemorrhagic cystitis in solid organ transplantation, especially in renal transplant recipients. In most cases, the disease is self-limited. However, some patients may have a protracted course. Although no particular antiviral agent has been identified as the gold standard of therapy, cidofovir has been found to be effective in a number of bone marrow transplant recipients. In this study, we report a five-yr-old boy who presented with adenovirus-associated hemorrhagic cystitis 68 days after renal transplant and was successfully treated with reduction of immunosuppression and an intermediate dose of intravenous cidofovir.
