Monitoring of human cytomegalovirus, HHV-6 and HHV-7 infection in kidney transplant recipients by molecular methods to predict HCMV disease after transplantation: a prospective study.

Objectives: Recently, highly sensitive molecular assays to detect HCMV, HHV-6 and HHV-7 have been developed but their ability to detect patients at high risk for disease is unclear.

Methods: The positive predictive values (PPV) of pp65-antigenemia, quantitative plasma DNA and pp67-mRNA for CMV-disease were prospectively compared in 82 transplant recipients (72 renal, 10 pancreas-kidney) without CMV-prophylaxis. In addition, the prevalence of HHV-6 and HHV-7 infection were assessed using qualitative PCR.
