Elizabethkingia meningoseptica (Chryseobacterium meningosepticum) bacteraemia: a series of 12 cases at Prince Sultan Military Medical City KSA

The aim of this study was to describe the epidemiological data, clinical features and outcome of patients with Elizabethkingia meningoseptica bacteraemia and to report the antimicrobial susceptibility pattern. All patients with E. meningoseptica bacteraemia were retrospectively recruited at the Prince Sultan Military Medical City, Riyadh, Saudi Arabia, between June 2013 and May 2019. Epidemiological data, clinical features and patient outcome, as well as antimicrobial susceptibilities of E. meningoseptica, were collected from patient electronic medical records. Twelve patients (eight male and four female) with E. meningoseptica bacteraemia were included in the study. Eleven patients acquired the infection from the hospital, five of whom were in the intensive care unit. All patients had one or more underlying medical conditions or interventions, including chronic illness (eight cases), major surgery (three cases), pulmonary fibrosis (one case), sickle-cell anaemia (one case) and end-stage renal disease (one patient on haemodialysis). Eleven patients had a prolonged stay in the hospital (≥3 months), and nine patients had received prolonged antibiotic therapy. Three patients had polymicrobial bacteraemia, including Serratia marcescens (two cases) and Enterococcus faecalis (one case). All E. meningoseptica isolates were susceptible to trimethoprim/sulfamethoxazole, piperacillin/tazobactam and moxifloxacin but showed a high degree of resistance to β-lactam antibiotics, aminoglycosides and carbapenems. These findings have important implications for the clinician selecting optimal antimicrobial regimens for patients with risk factors for E. meningoseptica infection.
