“…Despite being indirect, the data may suggest a better immune reconstitution after PT-Cy than after anti-thymocyte globulin (ATG), 8,9 infections (in particular of viral origin) occur frequently in the early post-transplant period after PT-Cy; 10 this may explain our findings of higher NRM and worse survival among CMV+ patients, events that are possibly related to the high cumulative incidence of CMV infectious episodes observed here in the cohorts 3 and 4. In addition, unfortunately the treatment with the available anti-CMV agents may be complicated by myelotoxicity and/or renal impairment, therefore this may conduct ultimately to fatal complications, even if the final event is different from the CMV infection itself.…”
