  1. CMV cytomegalovirus, UCBT unrelated cord blood transplant, MAC mieloablative conditioning, CsA cyclosporine A, Post-Cy post-transplant cyclophosphamide, allo-HSCT allogeneic hematopoietic stem cell transplantation, GvHD graft versus host disease, CSRV common seasonal respiratory virus, LRTD lower respiratory tract disease, IST immunosuppression systemic treatment.
  2. a52 patients were suspected to have possible/probable LRTD and 43 patients had positive PCR test for one or more common seasonal respiratory virus/es in the upper and/or lower respiratory tract specimens. Among the 43 cases, 13 had possible and 30 proven LRTD, since the later had CSRV detected in BAL specimens.
