Clinical features and molecular epidemiology of carbapenem-resistant Enterobacterales infection in children
Abstract
OBJECTIVES: To study the clinical features of children with carbapenem-resistant Enterobacterales (CRE) infection and the molecular characteristics of isolated strains.
METHODS: A retrospective analysis was performed on the clinical data and infection status of the children who were hospitalized in Guangdong Provincial People's Hospital from January 2018 to June 2021. A total of 1 098 non-repetitive strains of Enterobacterales were obtained. Drug sensitivity test, PCR amplification, and resistance-related gene sequencing were performed for 66 isolated CRE strains to observe molecular epidemiology.
RESULTS: Among the 1 098 strains of Enterobacterales, the detection rate of CRE was 6.01% (66/1 098). The 66 CRE strains were isolated from 66 children, among whom there were 37 boys (56%) and 29 girls (44%), with an age of 2 days to 14 years. Among these 66 children, 16 (24%) had an age of 36 months. The children with CRE were mainly distributed in the department of neonatology (38 children, 58%) and the pediatric intensive care unit (17 children, 26%). The top three types of specimens with CRE detection were respiratory specimens (48%), midstream urine specimens (21%), and blood specimens (17%). The CRE strains were mainly Klebsiella pneumoniae (45 strains, 68%), Escherichia coli (12 strains, 18%), and Enterobacter cloacae (6 strains, 9%), with high resistance to carbapenems (such as imipenem and ertapenem), penicillin, and cephalosporins, slightly high resistance to commonly…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 66 participants or records.
