We examined vancomycin-resistant enterococci (VRE)-directed antimicrobial use and VRE bacteremia in a cohort of allogeneic hematopoietic cell transplantation patients from a center where VRE screening is standard prior to transplant. In this cohort, VRE bacteremia (VREB) was infrequent. In patients without VREB, colonized patients received VRE therapy more often than noncolonized patients.Infect Control Hosp Epidemiol2018;39:730–733

Abstract Background Despite progress in diagnostic, prevention and treatment strategies, invasive mold infections (IMI) remain leading cause of mortality in allogeneic hematopoietic cell transplant recipients (allo-HCT-recipients). Methods We describe the incidence, risk factors, and mortality of allo-HCT-recipients with proven/probable IMI in a retrospective single-center 10-year (01.01.2010-01.01.2020) cohort study. Results Among 515 allo-HCT-recipients, 48 (9.3%) patients developed 51 proven/probable IMI: invasive aspergillosis (IA; 34/51, 67%), mucormycosis (9/51, 18%) and other molds (8/51, 15%). Overall 35/51 (68.6%) breakthrough-IMI (bIMI) were identified: 22/35 (62.8%) IA and 13/35 (37.1%) non-IA IMI. One-year IMI cumulative incidence was 7%: 4.9% and 2.1% for IA and non-IA IMI, respectively. Fourteen (29.2 %), 10 (20.8%), and 24 (50.0%) patients were diagnosed during the first 30, 31-180, and >180 days post-HCT, respectively. Risk factors for IMI included: prior allo-HCT (SHR:4.06, p=0.004) and ≥grade-2 acute graft-versus-host disease (aGvHD; SHR: 3.52, p<0.001). All-cause 1-year mortality was 33% (170/515): 48% (23/48) and 31.5% (147/467) for patients with and without IMI (p=0.02). Mortality predictors included: disease relapse (HR:7.47, p<0.001), aGvHD (HR:1.51, p=0.001), CMV-serology-positive recipients (HR:1.47, p=0.03), and IMI (HR:3.94, p<0.001). All-cause 12-week mortality for patients with IMI was 35.4% (17/48): 31.3% (10/32) for IA and 43.8% (7/16) for non-IA IMI (logrank 0.47). At 1-year post-IMI diagnosis, 70.8% (34/48) of patients were dead. Conclusions IA mortality has remained relatively unchanged during the last two decades. More than two thirds of allo-HCT-recipients with IMI die by 1-year post-IMI diagnosis. Dedicated intensified research efforts are required to further improve clinical outcomes.
