This cross-sectional study analyzes factors associated with the development of CMV-specific CD8+ response, measured by IFNg production after cytomegalovirus (CMV) peptide stimulation, in CMV-seropositive solid organ transplantation candidates. A total of 114 candidates were enrolled, of whom 22.8% (26/114) were nonreactive (IFNγ < 0.2 IU/mL). Multivariate(More)
To evaluate the usefulness of the secretion of interferon-γ (IFNγ) by cytomegalovirus (CMV)-specific CD8+ T cells to determine the risk of CMV reactivation in critically ill non-immunosuppressed patients. Two-center prospective cohort study including critically ill non-immunosuppressed CMV-seropositive patients admitted between December 2012 and March 2013.(More)
Cytomegalovirus (CMV), a member of the β-herpesvirus family, is a major complicating infection in transplant patients. CMV latency has a long-term impact on CD8+ T-cell differentiation. It is unclear, however, whether this effect can be detected in one-year period. To investigate this, we analyzed the remodeling of the CD8+ T-cell compartment during the(More)
The present study aimed to determine whether antiviral prevention strategies against cytomegalovirus (CMV) infection used in high-risk D+R- solid organ transplanted patients can modulate the impact of CMV replication on CD8(+) T-cell differentiation. The different CD8(+) T-cell subpopulations were measured at a single point when at least one year had(More)
