Valganciclovir prophylaxis for cytomegalovirus infection in thoracic transplant patients: retrospective study of efficacy, safety, and drug exposure.

Oral ganciclovir (GCV) was replaced by prodrug valganciclovir (vGCV) for cytomegalovirus (CMV) prophylaxis. We assessed retrospectively (2005-2007) vGCV effectiveness and safety during prophylaxis and 4 months after, in heart (HTx) and lung transplantation (LTx), including lung transplant for cystic fibrosis (CFTx). Patients with stable renal function received vGCV 900 mg daily during 3-6 and 8-12 months in HTx and LTx.
