E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess whether the incidence of hCMV infection after renal transplantation in the group of patients without receiving prophylactic antiviral therapy (pre-emptive, A2 and B2 groups) will be significantly higher among those patients without hCMV-specific cellular response (memory / effector T cells against antigen hCMV IE-1) (group B2) compared to individuals with detectable hCMV-specific cellular response (group A2) using IFN-gamma ELISPOT technique |
Evaluar si la incidencia de infección por hCMV tras el transplante renal en el grupo de pacientes sin recibir terapia antiviral profiláctica (pre-emptive, grupos A2 y B2) será significativamente mayor entre aquellos pacientes sin respuesta celular hCMV-específica (células T memora/efectoras frente al antígeno IE-1 de hCMV) (grupo B2) en comparación con aquellos indivíduos con respuesta celular detectable hCMV-específica (grupo A2) mediante técnica de ELISPOT IFN-gamma antes del trasplante |
|
E.2.2 | Secondary objectives of the trial |
To evaluate-the incidence of late HCMV infection after Receiving prophylactic treatment for 3 months in the group of patients without T cell response memory / effector antigen against hCMV IE-1 (group B1) Compared to Individuals with positive ELISPOT (detection T cell memory / effector antigen against hCMV IE-1) (group A1). Assess the effect of type of preventive treatment in the group of patients With the same result of anti-hCMV Elispot. To Assess the Ability of spontaneous viral clearance in relation to the response of memory / hCMV-specific to each single EVALUATED by ELISPOT effector. To study the behavior in time of the response of hCMV-specific cellular memory (T) by the ELISPOT technique after transplantation under immunosuppressive therapy based on anti-regime clacineutínico Both in patients under antiviral prophylactic strategy or anticipated (Preemptive). |
Evaluar la incidencia de infección tardía por hCMV después de recibir tratamiento profiláctico durante 3 meses en el grupo de pacientes sin respuesta celular T memoria /efectoras frente al antígeno IE-1 de hCMV (grupo B1) en comparación con aquellos individuos con ELISPOT positivo (detección de células T memoria /efectoras frente al antígeno IE-1 de hCMV) (grupo A1). Evaluar el efecto del tipo de tratamiento preventivo dentro del grupo de pacientes con el mismo resultado del Elispot anti-hCMV. Evaluar la capacidad de aclaramiento viral espontáneo en relación a la respuesta de memoria/efectora hCMV-específica de cada individuo evaluada por técnica de ELISPOT. Estudiar el comportamiento en el tiempo de la respuesta de memoria hCMV-específica celular (T) mediante la técnica ELISPOT después del trasplante bajo terapia inmunosupresora basada en un régimen anti-clacineutínico, en pacientes tanto bajo estrategia profiláctica antiviral o anticipada (Preemptive). |
