Community respiratory virus infections in bone marrow transplant recipients: the M.D. Anderson Cancer Center experience

Abstract

Community respiratory virus (CRV) infections are common among bone marrow transplant (BMT) recipients during community outbreaks. At M.D. Anderson Cancer Center (MDACC), experience with CRV infection in this population over the past decade suggests that BMT recipients in the preengraftment phase are at special risk of progression of upper respiratory tract infection (URTI) to pneumonia. After pneumonia is established, no currently available therapy substantially reduces mortality. For BMT recipients with respiratory syncytial virus URTIs, treatment with ribavirin and intravenous immunoglobulin may be helpful in preventing progression to pneumonia and thus in reducing mortality, but this approach requires confirmation in controlled clinical trials. Prevention of CRV infection in this vulnerable patient population is crucial to reducing morbidity and mortality. Aggressive infection control precautions, which have been in effect at MDACC since 1994, have reduced nosocomial transmission of these potentially lethal infections.
