AbstractLung transplantation recipients are at high risk for herpesvirus infections. We evaluated the effect of combined cytomegalovirus (CMV) prophylaxis on CMV pneumonia, acute rejection episodes (ARE), lymphocytic bronchitis/bronchiolitis (LB), and obliterans bronchiolitis (OB) diagnosed in 180 transbronchial biopsies (TBB) of lung transplant recipients. At our center, 25 patients (control group; 1999-2002) received acyclovir for 12 months and 21 recipients (study group; 2003-2007) received combined CMV prophylaxis consisting of CMV-IG (Cytotect Biotest) for 12 months and ganciclovir or valganciclovir from postoperative day 21 for 3 weeks. Among the study group (since 2005), CMV shell vial viral culture and Epstein-Barr virus (EBV), human herpesvirus-6 (HHV-6), and HHV-7 DNA were determined on BAL specimens. In the study group, the number of LB was significantly lower than in the control group (2% vs 11%; P= .04). Similar results were obtained for ARE (6% vs 17%; P= .04). No difference was observed in OB (5% vs 5%; P= .53, NS). A reduction trend was found in CMV pneumonia (2% vs 7%; P= .23, NS). Logistic regression analysis showed a relationship between prophylaxis and a reduced prevalence of ARE (odds ratio [OR] 3.25, confidence interval [CI] 1.12-9.40; P= .03). Finally, in the study group, BAL EBV-DNA positivity and EBV-CMV coinfections were low (6% and 0%, respectively) compared with other herpesviruses and with the literature. Our data suggested the efficacy of combined CMV prophylaxis to prevent ARE and LB, 2 risk factors for chronic rejection, and a possible role to reduce the trend toward CMV pneumonia and EBV infections.
