Cytomegalovirus (CMV) infection is a significant problem in transplantation. In this study, a quantitative PCR test was compared with the CMVpp65 antigenemia assay not only in the diagnosis CMV infections but especially in the monitoring of viral loads during ganciclovir treatment of CMV disease in individual renal transplant patients. Altogether 342 blood specimens were obtained from 116 patients. Blood specimens were used for Cobas Amplicor Monitor plasma PCR and for the pp65 assay. Also shell vial culture was performed. The patients with a positive pp65 finding were monitored for CMV weekly during ganciclovir treatment and/or until the antigenemia subsided. CMV was detected in 31/116 (27%) patients, of whom 14 (12%) developed CMV disease and were treated with ganciclovir. CMV was found by shell vial culture in 13/14 cases, but by PCR and pp65 test in all 14 patients. CMV was detected in 156 (45%) samples; by PCR in 121/156 (range 344-103,000 copies/ml) and by pp65 test in 138/156 (range 1-1,000 positive cells/50,000 leukocytes) and by culture in 59/156 (38%) only. The peak viral loads were significantly (P<0.0001) higher in CMV disease than in untreated infections (19,650 vs. 379 copies/ml, and 100 vs. 5pp65 positive cells). In the monitoring of individual patients, the time-related CMV-DNAemia and pp65 antigenemia correlated well during the treatment of CMV disease. In conclusion, Cobas Amplicor Monitor plasma PCR and CMVpp65 antigen assays can be equally used in the diagnosis CMV infection and in the monitoring of viral load during antiviral treatment.
