ABSTRACT

Objective To analyze the etiology of empyema in pediatric population, during the massive immunization age with PCV7 and PCV13.
Material y Methods. Epidemiologic study. The sample was constituted by all pediatric empyema cases registered during 2010- 2012. We evaluated clinical presentation, PVC exposition, bacteria isolated and antimicrobial sensitivity. Frequencies and proportions in quantitative variables were determinate. Empyema incidence rates in exposed and non exposed children to PCV7 or PCV13, RR, I.C. 95%.
Results. 32 patients were diagnosed with empyema, average 45.6 months of age. 65.6% had not identified any etiologic agent. Streptococcus pneumoniae was identified in 25 %. Pneumococcal empyema incidence rate 11.1 x 100 cases during 2010- 2012 was significantly low than during 2001- 2002 period 53.8 x 100 cases. Chi² 0.000
Discussion. Children exposed to PCV7 or PCV13 had lower empyema rates than non immunizated children. S. pneumoniae is the prevalent agent related to empyema in this study.
