Prevention of cytomegalovirus infection in the pediatric renal transplant recipient.
Cytomegalovirus (CMV) infection is the most important single infectious complication of organ transplantation, affecting more than 70% of transplant recipients. Its emergence as a major pathogen has coincided with the use of cytotoxic therapy. Manifestations of serious CMV disease include: pneumonia, hepatitis, gastrointestinal disease, leukopenia and chorioretinitis. CMV is associated with superinfection with opportunistic organisms, graft failure and increased mortality. Serious infection most frequently occurs with primary CMV infection in which latently infected cells from CMV-positive donors are given to seronegative recipients. Pediatric patients who have a lower pre-transplant rate of CMV seropositivity are at particularly high risk of developing serious CMV disease. Preventative efforts range from the ideal but impractical use of only CMV-negative donors (organ and blood products), to the use of CMV hyperimmune globulin and antiviral chemotherapy. Data support the use of prophylactic hyperimmune globulin and preliminary information supports the use of prophylactic high-dose acyclovir in renal transplant patients. Prophylactic gancyclovir alone or with hyperimmune globulin and pre-transplant vaccination with live-attenuated Towne strain CMV vaccine remain investigational.
