[Chemotherapy-induced febrile neutropenia in a Tunisian Department of Pediatric Oncology]. / Neutropénie fébrile chimio-induite dans une unité d'oncologie pédiatrique tunisienne.

Chemotherapy-induced neutropenia (FN) is the most common infectious complication in pediatric oncology. To our knowledge, no pediatric research has been published in Tunisia. The purpose of our study was to describe the features of FN among Tunisian children and to investigate factors correlated with FN. We conducted a prospective study of children with chemotherapy-induced FN at the Department of Pediatric Medicine A of the Tunis Children´s Hospital from July 2019 to December 2019. We recorded 50 episodes of FN in 32 patients whose mean age was 5.3 years (3 months-16 years). We included 26 patients with solid tumors (81%) and six patients with hemopathies (18.7%). The mean time between last treatment and fever onset was 10.67 days. Bacteriological investigation was contributory in 18% of cases and mainly showed gram positive cocci. Therapeutic protocol including 1st line empirical antibiotic therapy (3rd generation cephalosporin with aminoglycoside) was effective in 62% of cases. Mortality rate of patients with FN was 2%. The statistical study did not reveal any factor of correlation with late-onset neutropenia. In conclusion, our results are consistent with literature data on bacteriological documentation and mortality. Our 1st line treatment option based on 3rd generation cephalosporin associated with aminoglycoside was effective in 2/3 of the cases. In the future, oral antibiotics may be considered in patients at low risk for infection.
