[Salmonella infections in children: a retrospective study over a four-year period].

Objectives: Epidemiological state of salmonella infections in Languedoc-Roussillon (France) and discussion of therapeutic indications.

Material And Method: Retrospective study over a four-year period of paediatric salmonella infections requiring hospitalisation in Montpellier University Hospital. Analysis of clinical, bacteriological, laboratory and therapeutic data.

Results: One hundred and sixty nine cases of paediatric salmonella infections have been investigated. The clinical triad consisted of diarrhea, abdominal pain and fever. Six severe cases have been observed and seemed to have been independent of patient's background. Laboratory findings showed inconstantly hyperleucocytosis and increase in CRP levels. Stool analysis remained the reference laboratory test to detect salmonella. Two major strains of salmonella have been identified: Salmonella enterica subsp. enterica serovar Typhimurium and Enteriditis. Treatments have been essentially symptomatic but 20% of the children (n=34) required antibiotic therapy. A favourable outcome was observed in all the children.

Discussion: Incidence of salmonella infections is increasing in France, particularly in the Languedoc-Roussillon area. Diagnosis of mild forms is generally easy but certain patient background seems to expose to severe forms. Treatment of salmonella infections is mainly symptomatic, only severe or specific cases (young age, immunodepression...) requiring antibiotic treatment. The growing antibiotic use and the increasing of resistance are currently the main problems in the management of salmonella infections. Those infections remain a public health problem in Languedoc-Roussillon.
