Article Title: Bacteremia due to carbapenem-resistant Enterobacteriaceae in neutropenic patients with hematologic malignancies
Abstract: Objectives To determine the prevalence, risk factors, treatments, and outcomes of bloodstream infections (BSIs) due to carbapenem-resistant Enterobacteriaceae (CRE) in adult neutropenic patients with hematologic malignancies. Methods We reviewed all BSIs between 2008 and 2012 in this population at two New York City oncology centers. A case-control study was conducted to identify CRE BSI risk factors, using three controls of non-CRE BSIs per case. Results CRE caused 43 (2.2%) of 1992 BSIs overall and 4.7% of Gram-negative bacteremias. Independent risk factors for CRE BSI were prior β-lactam/β-lactamase inhibitor (adjusted odds ratio [aOR] 3.2; P = 0.03) or carbapenem (aOR 3.0; P = 0.05) use, current trimethoprim-sulfamethoxazole (aOR 24; P = 0.001) or glucocorticoid (aOR 5.4, P = 0.004) use, and having a prior CRE culture (aOR 12; P = 0.03). Patients with CRE bacteremia had a median of 52 h from culture collection until receipt of active therapy. They had a 51% BSI-related mortality rate, with a median of 4 days from bacteremia onset until death. CRE-active empirical therapy was associated with a lower 30-day mortality rate (17% vs. 59%; P = 0.08). Conclusions CRE are lethal emerging causes of bacteremia in neutropenic patients. New strategies are needed to shorten the delay in administration of CRE-active agents and improve outcomes in this vulnerable population. © 2016 The British Infection Association
