BACKGROUND: Invasive Salmonella infections are highly prevalent worldwide. Clinical data of childhood invasive Salmonella infections from China are limited.
METHODS: Data of hospitalized children <18 years old with invasive Salmonella infections from 2016 to 2020 in Shenzhen Children's Hospital in Shenzhen were retrospectively collected. Serotypes and antimicrobial susceptibility tests of the invasive Salmonella isolates were performed.
RESULTS: Sixty-three cases were enrolled during the 5-year study period including 8 in 2016, 11 in 2017, 16 in 2018, 6 in 2019 and 22 in 2020. The median age was 15 months (interquartile range, 11-22 months), and 79.4% (50 cases) were <2 years of age. Underlying diseases were found in 28.6% (18 cases) of the patients with a great variety, but no cases of malaria or HIV infection were identified. Most of the invasive Salmonella cases were bloodstream infections (84.1%), followed by osteoarthritis (11.1%) and meningitis (4.8%). Gastroenteritis (49.2%) and pneumonia (28.6%) were found to be the major manifestations among the patients. Furthermore, invasive Salmonella infections resulted in the death of 3 children (4.8%). Salmonella enteritis (12 cases; 15.9%) and Salmonella typhimurium (9 cases; 19.0%) as the most common serovars were identified. The resistance rates of Salmonella strains to ceftriaxone, ceftazidime and cefepime were also measured to be 17.5%, 17.5% and 9.5%, respectively.
CONCLUSIONS: An increasing number of childhood invasive Salmonella infections with a broad range of serotypes was observed in Shenzhen, China. It is critical to pay attention to the antimicrobial resistance of the isolates taken from children with invasive Salmonella infections.
