Prophylactic therapy with valganciclovir in high-risk (cytomegalovirus D+/R-) kidney transplant recipients: a single-center experience.
BACKGROUND
A prospective study was performed in kidney transplant patients at risk of developing cytomegalovirus (CMV) infection (CMV D+/R-). They were treated with valganciclovir (VGC) for 3 months as prophylactic therapy. The aim was to determine the safety and efficacy of prophylactic therapy with VGC.


METHODS
Antigenemia and/or polymerase chain reaction CMV was routinely performed every 2 weeks up to month 3, monthly to month 6, and every other month until the end of the first year posttranplantation, as well as when clinically indicated.


RESULTS
From July 2007 to April 2010, 366 renal transplantations were performed at our center, including 34 (9%) high-risk patients for CMV infection. The median age was 47 years; 19 were males and 15 females. Twelve (35%) patients developed CMV infections: 10 (34%) gastrointestinal disease and 3 viral syndromes. The timing of the clinical manifestations was 16% (3/12) between months 1 and 3, 75% (8/12) between months 4 and 6, and 8% (1/12) in month 9 posttransplantation.


CONCLUSIONS
Treatment with intravenous ganciclovir followed by oral VGC was successful in all patients. No opportunistic infections or allograft rejection were observed; only 1 patient developed thrombocytopenia as an adverse event to VGC.
