Improved outcome from invasive adenovirus infection in pediatric patients after hemopoietic stem cell transplantation using intensive clinical surveillance and early intervention.

Adenovirus is a common cause of morbidity and mortality after hemopoietic stem cell transplantation in children. Recently the incidence, risk factors, and outcome of such infections have been better defined using improved virologic detection methods, in particular polymerase chain reaction. We have introduced intensive virologic surveillance for adenovirus in our institution including at least weekly polymerase chain reaction testing of blood and stool samples.
