Efficacy of ß-lactam/ß-lactamase inhibitor combinations for the treatment of bloodstream infection due to extended-spectrum-ß-lactamase-producing enterobacteriaceae in hematological patients with neutropenia

Abstract

ß-Lactam/ß-lactamase inhibitors (BLBLIs) were compared to carbapenems in two cohorts of hematological neutropenic patients with extended-spectrum- ß-lactamase (ESBL) bloodstream infection (BSI): the empirical therapy cohort (174 patients) and the definitive therapy cohort (251 patients). The 30-day case fatality rates and other secondary outcomes were similar in the two therapy groups of the two cohorts and also in the propensity-matched cohorts. BLBLIs might be carbapenemsparing alternatives for the treatment of BSI due to ESBLs in these patients.
