Incidencia de sepsis precoz por Streptococcus agalactiae en recién nacidos del Centro Hospitalario Pereira Rossell en el período 2007-2015

Le résumé fourni par la source

BACKGROUND: Group B Streptococcus (GBS) disease remains the leading cause of early-onset sepsis (EOS) in developed countries despite effective prophylaxis strategies. AIMS: To describe the incidence, clinical features and mortality of GBS EOS in infants born at Centro Hospitalario Pereira Rossell (CHPR) and analyse failure of adherence to prevention strategies. METHODS: Retrospective review of EOS cases between 2007 and 2015 collected from the bacteriology laboratory database. RESULTS: Fifteen cases of GBS EOS were identified, with an incidence of 0.23% during the study period. Intrapartum antibiotic prophylaxis (IAP) was not administered in any of the cases. All infants were symptomatic within the first 15 hours of life, mainly due to respiratory signs (80%). In one case, GBS was isolated from spinal fluid. Mortality rate was 20%. All deaths occurred in the first 24 hours of life, corresponding two thirds to preterm infants. CONCLUSION: The incidence of GBS EOS at CHPR was similar to other centers where IAP is implemented. Better adherence to prophylaxis strategies could reduce the incidence.
