Abstract

To identify the risk factors for Salmonella bacteremia in infants and children with Salmonella gastroenteritis, a retrospective study of a 10-year period was conducted to evaluate 456 infants and children with culture-proven nontyphoidal Salmonella infection. Salmonella typhimurium was the most common isolate found. Among the 257 patients with gastroenteritis who had a concomitant blood culture performed, 50 exhibited bacteremia. Statistically significant differences were noted between patients with gastroenteritis and bacteremia and those without bacteremia in duration of fever ±5 days (P<0.001; OR, 5.6; 95% CI, 2.6-12.1) and infection with group D1 Salmonella (P<0.001; OR, 6.5; 95% CI, 2.5-16.9) after adjustment for multivariate analysis. Of the 320 Salmonella strains that were serotyped, Salmonella panama was shown to be strongly associated with bacteremia (P<0.001) in children with gastroenteritis. In summary, in children with nontyphoidal Salmonella gastroenteritis, prolonged fever lasting 5 days or more and infection with a specific Salmonella serotype were risk factors closely associated with development of bacteremia.
