title: Therapeutic implication of quantitative pp65 antigen assay in living renal transplant in a high seroendemic population.
abstract: Various methods have been used to diagnose cytomegalovirus (CMV) infection/disease; however, pp65 antigenemia assay has emerged as a good marker for CMV disease in a high seroendemic population. We studied the role of quantitative pp65 antigen assay in live related renal transplant recipients in a high seroendemic population. Between November 1998 and May 2003, a total of 350 blood samples from 250 symptomatic patients were tested by quantitative pp65 antigen assay; 14% of the patients tested positive. There were 5 (14%) low-positive and 30 (86%) high-positive patients. All high-positive patients had CMV disease. The response to antiviral therapy monitored by the assay was dramatic, and one low-positive patient responded to reduction in immunosuppression. In conclusion, pp65 antigen assay is a good test for diagnosing CMV disease and monitoring response to antiviral therapy in a high seroendemic population.
