Salmonella Gastroenteritis in Children: Six-Year Experience in İstanbul, Turkey

INTRODUCTION:The aim of this study was to evaluate the demographic and clinical characteristics and treatment outcomes of children with Salmonella gastroenteritis.METHODOLOGY:We retrospectively reviewed the medical records of pediatric patients aged between 1 month and 18 years with the diagnosis of Salmonella gastroenteritis between May 2015 and December 2021.RESULTS:A total of 172 children diagnosed with Salmonella gastroenteritis, including 113 outpatients and 59 hospitalized children, were included in this study. There were 95 (55.2%) males and 77 (44.8%) females with a median age of 59.5 months (interquartile range [IQR]: 33.5-96 months, min-max: 1-205 months). The most common clinical symptoms were diarrhea (n = 166, 96.5%), fever (n = 113, 65.7%) and abdominal pain (n = 73, 42.4%). Bloody diarrhea was seen in 19.2% of patients. Fifty (29.1%) of the Salmonella species could not be typed. Serogroup D (n = 106, 61.6%) was the predominant serogroup isolated from stool cultures, followed by serogroup B (n = 16, 9.3%). 62.2% of the isolates were susceptible to ampicillin, 97.7% to ciprofloxacin, 98.8% to trimethoprim-sulfamethoxazole, and 98.8% to ceftriaxone. Fever, vomiting, and underlying disease occurred more frequently in hospitalized patients than in outpatients (p: 0.005, p: 0.000, p: 0.000, respectively). C-reactive protein value was found to be higher in hospitalized patients (p: 0.000).CONCLUSIONS:Salmonella should be considered as a causative agent in pediatric patients with abdominal pain, fever, and bloody-mucous diarrhea, and patients with severe clinical conditions should be hospitalized and antibiotic therapy initiated if indicated.
