Description
Summary:INTRODUCTION: Enterobacter can be included in the group of extended spectrum β-lactamases (EBSL)-producing bacteria, though few studies exist evaluating risk factors associated with this microorganism. A retrospective cohort study was conducted to determine risk factors associated with ESBL-producing-Enterobacter and mortality METHODS: A retrospective cohort study with 58 bacteremia caused by ESBL-producing-Enterobacter (28 cases) and non-ESBL (30 cases) RESULTS: Risk factors associated with ESBL-Enterobacter were trauma, length of hospitalization, admission to the intensive care unit, urinary catheter and elective surgery (p< 0.05). The survival curves were similar for ESBL and non-ESBL CONCLUSIONS: ESBL-producing-Enterobacter bacteremia is prevalent and the survival curve was similar to non-ESBL-producing strains. INTRODUÇÃO: Enterobacter pode ser incluído no grupo de bactérias produtoras de β-lactamases de espectro estendido (ESBL), mas existem poucos estudos avaliando fatores de risco para ESBL. Nós realizamos uma coorte retrospective para determiner fatores de risco associados com Enterobacter produtores de ESBL MÉTODOS: Uma coorte retrospectiva com 58 bacteremias por Enterobacter ESBL (28 casos) e não-ESBL (30 casos) RESULTADOS: Fatores de risco para ESBL-Enterobacter foram trauma, tempo de internação, admissão em UTI, sonda vesical e cirurgia eletiva (p<0.05). A mortalidade foi similar entre ESBL e não-ESBL CONCLUSÕES: Enterobacter produtor de ESBL é prevalente e a curva de mortalidade foi semelhante com o grupo não-ESBL.
