Community acquired respiratory virus infections in adult patients undergoing umbilical cord blood transplantation.

ABSTRACT: Characteristics and risk factors (RFs) of community-acquired respiratory virus (CARV) infections after umbilical cord blood transplantation (UCBT) are lacking. We retrospectively analyzed CARV infections in 216 single-unit myeloablative UCBT recipients. One-hundred and fourteen episodes of CARV infections were diagnosed in 62 (29%) patients. Upper respiratory tract disease (URTD) occurred in 61 (54%) whereas lower respiratory tract disease (LRTD) in 53 (46%). The 5-year cumulative incidence of CARV infection was 29%. RFs for developing CARV infections were: prednisone-based graft-versus-host disease (GVHD) prophylaxis and grade II-IV acute GVHD. RFs analysis of CARV progression to LRTD identified 2007-2009 period and absolute lymphocyte count (ALC) < 0.5 × 10⁹/L. ALC < 0.5 × 10<
