Cytomegalovirus disease among donor-positive/recipient-negative lung transplant recipients in the era of valganciclovir prophylaxis

Valganciclovir prophylaxis among donor-positive/recipient-negative lung transplant recipients delayed but did not eliminate CMV disease or CMV-related deaths and was limited by toxicity and ganciclovir-resistance. Our experience suggests that valganciclovir at reduced-doses or for less than 6 months is sub-optimal in preventing CMV disease.
