The incidence of CMV infection in pediatric renal transplant recipients has increased as immunosuppression levels deepen following the use of newer immunosuppressive agents. It has been thought that 3-5 months of anti-CMV prophylaxis offers sufficient protection for these patients. We present a case of late-onset fatal CMV disease in a pediatric renal transplant recipient who received prolonged anti-CMV prophylaxis while on "quadruple" immunosuppression with daclizumab, mycophenolate, tacrolimus, and prednisone. Our case has prompted us to reassess CMV surveillance, prophylaxis, and immunosuppression levels in our pediatric renal transplant patients.
