Study Arms (2)
Control
ACTIVE COMPARATORControl Group (universal prophylaxis + pre-emptive therapy; 6+6): The recommendation of the Spanish Consensus Document will be followed according to the strategy described below: * Universal prophylaxis with valganciclovir (900 mg/24h, corrected for renal function) up to month +6. The use of associated immunotherapy (e.g., anti-CMV hyperimmune immunoglobulin) will depend on each center's clinical practice. During this period, the treatment of blips of viral replication detected during the usual clinical follow-up of patients will depend oneach center's clinical practice. * Pre-emptive therapy guided by viral load from month +6 to month +12. For a viral load above\> 38 copies/mL (\> 35 IU/mL) and depending on each center's clinical practice, treatment with valganciclovir may be initiated (900 mg/12h, corrected for renal function).
Experimental
EXPERIMENTALExperimental Group (reduced prophylaxis + immuno-guided prophylaxis; 3+9): * Universal prophylaxis with valganciclovir (900 mg/24h, corrected for renal function) up to month +3. The use of associated immunotherapy (e.g., anti-CMV hyperimmune immunoglobulin) will depend oneach center's clinical practice. During this period, the treatment of blips of viral replication detected during the usual clinical follow-up of the patients will depend on the each center's clinical practice. * Immuno-guided prophylaxis. This will consist of a monthly determination of cellular immunity by QF-CMV from month +3 to month +12.
Interventions
Valganciclovir is a L-valyl ester of ganciclovir that exists as a mix of 2 diastereomers. After administration, both are converted to ganciclovir by esterases. Ganciclovir is a synthetic analogue of 2'-deoxyguanosine, it inhibits replication of cytomegalovirus. In CMV-infected cells it's phosphorylated (phosphorylation is dependent on the viral kinase and occurs preferentially in virus-infected cells). Ganciclovir activity is due to inhibition of viral DNA synthesis by ganciclovir triphosphate.
