Herpesvirus Infections and Treatments

Cytomegalovirus (CMV) infection is the single most frequent infectious complication in renal transplant recipients. The aim of this study was to determine the incidence of latent and active infections with CMV during the first 3 months after kidney transplantation. From January 2000 to December 2001, 203 consecutive adult renal transplant recipients underwent weekly measurements of pp65 CMV antigen from the 4th to the 12th posttransplantation week. Latent infection (seropositivity) was found in 92% of the population. Primary infection occurred in 4.9% (10 of 203), among whom 66% were previously seronegative patients. Among the primary infection patients, 70% (7 of 10) developed severe disease. The overall incidence of viremia was 69.5%, being more frequent among cadaver recipients (79% vs 59%; P =.02). The overall incidence of CMV disease was 38.4% (78 of 203) with 24.6% classified as severe disease requiring antiviral therapy. In conclusion, our population showed a high prevalence of latent infection with viremia. Not all patients developed clinical disease. Most subjects experienced a mild spectrum of symptoms, probably due to the prospective search for active infection during the major risk period after kidney transplantation.
