Cytomegalovirus (CMV) remains an important cause of morbidity and mortality in lung transplant recipients. We investigated the incidence of CMV infection in relation to CMV prophylaxis, and recipient-donor CMV serotype, in a cohort of 250 consecutive lung transplant recipients. All patients received 3 months CMV prophylaxis with acyclovir (n = 67) or gancyclovir (n = 183). Recipient-donor CMV serotype matching was performed in patients receiving acyclovir: R + /D+(n = 38), R + /D−(n = 10), R − /D+(n = 1), R − /D−(n = 16), unknown (n = 2). Recipient-donor CMV serotype matching was not performed in patients receiving gancyclovir: R + /D+(n = 71), R + /D−(n = 42), R − /D+(n = 38), R − /D−(n = 31), unknown (n = 1). The overall incidence of CMV infection was 51% (n = 34) in the acyclovir group, and 42% (n = 77) in the gancyclovir group (p = 0.14). During the first 9 months after transplantation, the rate of CMV infection was higher in the acyclovir group (42%) compared with the gancyclovir group (30%) (p = 0.005). Multivariate analysis demonstrated the incidence of CMV infection during the first 9 months was higher for acyclovir prophylaxis (p<0.001) and R − /D+ serostatus (p<0.001) and lower with R − /D− serostatus (p = 0.02). In conclusion, gancyclovir significantly delays the onset of first CMV infection among lung transplant patients. CMV surveillance and choice of prophylaxis may be modified according to donor-recipient CMV serotype.
