Cytomegalovirus infection in lung transplant patients: the role of prophylaxis and recipient-donor serotype matching.
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.
