Cytomegalovirus (CMV) prophylaxis is one of the most controversial and challenging aspect in the management of patients underwent lung transplan-tation (LuTx). The aim of this study was to report the experience in terms of incidence of early discontinuation of CMV prophylaxis and of CMV reactivation in our LuTx center. A retrospective study was conducted including all LuTx recipients from January 2009 to December 2015. Clinical and virologic data were collected in a dedicated database. Two groups of patients were identified according to CMV reactivation or not: Group A and B, respectively. From 2009 to 2015, a total of 115 LuTx were performed. Table 1 shows our results. The main reason for early discontinuation was leukopenia and anemia. Forty-height out of 115 patients were affected by at least one episode of CMV reactivation; of those, 8 were diagnosed with CMV disease. Median time of CMV reactivation was 183 (43; 642) days from LuTx. Among those who underwent reactivation, 40 (83%) prematurely discontinued prophylaxis: more specifically, CMV viremia occurred in 36% of the cases within the first 30 days from prophylaxis discontinuation, in 36% between 30 and 90 days and the rest after 90 days. Finally, CMV reactivation was associated with a higher risk of ALAD. Our data confirm the difficulty of CMV management after LuTx. We have patients who reactivated during prophylaxis and subjects who did not reacti-vate CMV even if prophylaxis was early discontinued. Such results support the urgent need of new diagnostic tools and prophylactic strategies.

Abstract

Cytomegalovirus (CMV) prophylaxis is one of the most controversial and challenging aspect in the management of patients underwent lung transplan-tation (LuTx). The aim of this study was to report the experience in terms of incidence of early discontinuation of CMV prophylaxis and of CMV reactivation in our LuTx center. A retrospective study was conducted including all LuTx recipients from January 2009 to December 2015. Clinical and virologic data were collected in a dedicated database. Two groups of patients were identified according to CMV reactivation or not: Group A and B, respectively. From 2009 to 2015, a total of 115 LuTx were performed. Table 1 shows our results. The main reason for early discontinuation was leukopenia and anemia. Forty-height out of 115 patients were affected by at least one episode of CMV reactivation; of those, 8 were diagnosed with CMV disease. Median time of CMV reactivation was 183 (43; 642) days from LuTx. Among those who underwent reactivation, 40 (83%) prematurely discontinued prophylaxis: more specifically, CMV viremia occurred in 36% of the cases within the first 30 days from prophylaxis discontinuation, in 36% between 30 and 90 days and the rest after 90 days. Finally, CMV reactivation was associated with a higher risk of ALAD. Our data confirm the difficulty of CMV management after LuTx. We have patients who reactivated during prophylaxis and subjects who did not reacti-vate CMV even if prophylaxis was early discontinued. Such results support the urgent need of new diagnostic tools and prophylactic strategies.
