title: Cytomegalovirus disease occurring before engraftment in marrow transplant recipients.
abstract: Little information is available regarding the incidence, clinical course, and response to treatment of cytomegalovirus (CMV) disease that occurs before engraftment in marrow transplant recipients. We identified 25 patients over a 12.5 year period who developed CMV disease before achieving engraftment. Twelve cases were diagnosed during life, and 13 cases were diagnosed at autopsy. The lung was the site most commonly involved (92% of patients), and most of the patients (92%) were CMV seropositive. Significant copathogens were identified in 45% of the patients. All nine patients with CMV pneumonia died within 6 weeks after the diagnosis was made, and one of two patients with gastrointestinal disease also died 6 weeks after the diagnosis was made despite the administration of antiviral therapy. Surveillance cultures were not helpful in identifying patients at risk for disease. Histopathological examination of the lungs of patients with early CMV pneumonia only infrequently showed typical CMV lesions. In conclusion, CMV disease occurring before engraftment in CMV-seropositive recipients was uncommon, was frequently associated with the presence of other opportunistic pathogens, and was associated with a high fatality rate. Better diagnostic methods to identify patients at risk are required in the preengraftment period.
