Stable Incidence of Invasive Pneumococcal Disease in Children in Northern France From 2014 Through 2018.

Résumé

Background: The 13-valent pneumococcal conjugate vaccine (PCV13) has been recommended in France since June 2010. The aim of this study was to evaluate the trends in the incidence of invasive pneumococcal disease (IPD) resulting in hospitalization of children younger than 18 years of age, to identify the vaccination status of these patients and to analyze the serotypic evolution of the pneumococci involved in the various types of IPD. Methods: This multicenter retrospective study reviewed all admissions of children younger than 18 years of age for IPD from 2014 through 2018 in all hospitals with a pediatric or neonatal unit in northern France. Data completeness was obtained by matching 3 independent databases. The incidence of IPD resulting in hospitalization was calculated per age group. The clinical course and the vaccine and nonvaccine types were described overall and by the IPD type. Results: One hundred thirty cases of IPD were identified: 51 with bacteremia, 45 meningitis, 28 pneumonia or pleuropneumonia and 6 arthritis. The IPD incidence ranged from 2.4 to 3.0/100,000 in children under 18 years of age (95% confidence intervals, 1.4–3.3 and 1.9–4.1, respectively), and from 9.5 to 15.9/100,000 in children under 2 years of age, with no significant differences over time. Nonvaccine types were predominant (81%), mainly 24F, 23B and 10A. Vaccine serotype 3 was involved in 10 cases of IPD, 2 of which were in correctly vaccinated children. Two cases of IPD could have been prevented by vaccination. Neurologic sequelae affected 26% of these children (62% of those with meningitis). Six children died from IPD (5%). Conclusion: The incidence of IPD resulting in hospitalization remained stable in northern France during the study period, with no significant increase in nonvaccine types. Further surveillance is needed to adjust the vaccination strategy if necessary.
