Brief Summary

Hypothesis: Valganciclovir prophylaxis can be discontinued before 3 months in CMV-seropositive renal transplant recipients receiving induction thymoglobulin when developing CMV-specific cellular immunity after transplantation. Objective Meet the efficacy and safety of valganciclovir prophylaxis suspend in CMV-seropositive kidney transplant recipients with CD8 + cellular immunity CMV-specific transplant, receiving Thymoglobulin induction and maintain cellular immunity-specific CD8 + CMV after transplantation. Design: noninferiority clinical trial (study A) in CMV-seropositive kidney transplant recipients with CMV-specific cellular immunity pretransplant (Quantiferon reactive CMV) received induction with thymoglobulin Patients meeting inclusion criteria will be randomized to:

  • Control Arm: valganciclovir prophylaxis until day +90 as recommended by the International Consensus document of the TTS (Transplantation 2013:96:333-360).
  • Experimental arm: prophylaxis with valganciclovir and determination of CMV-specific cellular immunity day +15, +30, +45 and +60. Prophylaxis was discontinued when the patient developed CMV-specific cellular immunity. Patients who did not develop CMV specific immunity continue prophylaxis until day +90. Analysis: The incidence of CMV disease according to the strategy used was calculated using Kaplan-Meier curves that were compared using the log-rank test.

Outcome Measures

Primary Outcomes (1)

  • Incidence of CMV disease at 12 months after transplantation

    Incidence of CMV disease at 12 months after transplantation. Study the predictive value of the assay of CD8 + T cell immunity specific for defined CMV-patients in which they can stop prophylaxis. The definition of CMV disease was based on those recommended by the American Society of Trasnplantation criteria for use in clinical trials

    12 months

Secondary Outcomes (2)

  • Percentage of patients who recover CMV-specific CD8+ T-cell immunity in the posttransplantation period after receiving thymoglobulin induction therapy and valganciclovir prophylaxis

    12 months

  • Incidence of CMV replication

    12 months

Study Arms (2)

New profilaxis

EXPERIMENTAL

Prophylaxis is discontinued when the patient developed CMV-specific cellular immunity.

Drug: New profilaxis

Profilaxis recommended by TTS

ACTIVE COMPARATOR

Valganciclovir prophylaxis until day +90 as recommended by the International Consensus document of the TTS.

Drug: Profilaxis recommended

Interventions

Primary endpoint: incidence of CMV disease at 12 months after transplantation. Study the predictive value of the assay of CD8 + T cell immunity specific for defined CMV-patients in which they can stop prophylaxis. The definition of CMV disease was based on those recommended by the American Society of Trasnplantation for use in clinical trials (Humar A. Am J Transplant 2006; 6:262-74) criteria.

New profilaxis

Secondary end points: percentage of patients developing T cell immunity in CMV-specific transplantation after receiving timoglubulina induction and valganciclovir prophylaxis. T cell development inmnunidad CD8 + CMV-specific is defined as production of γ\> 0.2 interferon by CD8 + T cells stimulated by CMV-specific CMV antigens (QF reagent).

Profilaxis recommended by TTS
