Clinical characteristics and drug resistance of Elizabethkingia meningoseptica infection in a tertiary hospital in Hainan Province from 2021 to 2022
Objective To explore the clinical characteristics and drug resistance of Elizabethkingia meningoseptica(EM)nosocomial infection,so as to provide evidence for prevention of EM nosocomial infection and guiding the rational use of antibiotics.Methods A retrospective study was conducted of 67 patients with EM infection in a tertiary hospital from January 2021 to December 2022.The infective characteristics and drug resistance were analyzed.Results The cohort of 67 EM-infected patients was predominantly males aged≥60 years,with the most frequent source being the first district of the intensive care unit(ICU),followed by the respiratory medicine and emergency department(19.40%,13/67).The specimens were mainly isolated from respiratory tract(86.57%,58/67),of which sputum accounted for 49.25%(33/67),and alveolar lavage fluid accounted for 37.31%(25/67).The majority of EM infections occurred in patients with pre-existing respiratory conditions(49.25%,33/67),who generally experienced prolonged hospital stays and underwent invasive procedures,such as mechanical ventilation 94.03%(63/67),urinary catheterization(95.52%,64/67),and central venous catheterization(97.01%,65/67).Post-treatment,the improved rate of the 67 patients was 40.30%(27/67).Susceptibility testing demonstrated a high resistance rate of EM to cefoperazone-sulbactam,98.39%(61/62),contrasted by significant susceptibility to compound trimethoprim-sulfamethoxazole(TMP-SMX)/cotrimoxazole,doxycycline,minocycline,and piperacillin-tazobactam,with susceptibility rates exceeding 90%.Conclusions The patients infected with EM were almost elderly men with certain underlying diseases,experienced prolonged hospital stays,and had a history of invasive operations.The specimens of EM were mainly from Intensive Care Unit and isolated from respiratory tract.The strain showed high resistance to cefoperazone-sulbactam,whereas it remained highly susceptible to cotrimoxazole,doxycycline,minocycline and piperacillin-tazobactam,which may be considered as first-line treatment options.
