Mortality Risk and Antibiotic Therapy for Patients with Infections Caused by <i>Elizabethkingia</i> Species—A Meta-Analysis
Abstract
Background and Objectives: Patients with infections caused by Elizabethkingia species require prompt identification and effective antibiotic treatment since these spp. are typically resistant to multiple antibiotics and variable susceptibility patterns. Understanding the mortality risk of this disease is difficult because of the relatively low incidence of infections caused by Elizabethkingia spp. and the lack of published systematic evaluations of the risk factors for mortality. The aim of the present study was to investigate risk factors for mortality in patients with infections caused by Elizabethkingia spp. by conducting a meta-analysis of existing studies on these infections. Materials and Methods: Studies comparing patients who died from infections caused by Elizabethkingia spp. with patients who survived were considered for inclusion. Studies that reported one or more risk factors for mortality were considered. Clinical predisposing variables, predisposing comorbidities, and clinical outcomes of antibiotic treatment were among the risk factors for mortality. Results: The meta-analysis included twenty studies with 990 patients, and 298 patients (30.1%) died. The following risk factors for mortality were identified: intensive care unit admission, the need for mechanical ventilation, immunosuppressive or steroid therapy use, pneumonia, comorbid liver disease, and the use of inappropriate antimicrobial therapy. Conclusions: The use of appropriate antimicrobial therapy is critical for the effective management of infections caused by Elizabethkingia spp. Antimicrobial susceptibility testing would be a more reliable means of guiding treatment. The identification of the best antimicrobial drugs is needed to ensure optimal treatment recommendations for treating Elizabethkingia-related infections.
