- W2607181281 abstract "La información existente sobre la resistencia a los antibióticos se basa habitualmente en muestras de personas hospitalizadas. El objetivo fue evaluar la prevalencia de resistencia antibiótica de cepas de Staphylococcus aureus y Streptococcus pneumoniae de personas portadores nasales atendidas en las consultas de atención primaria según edad y sexo. Estudio transversal. Siete centros de salud del área de Barcelona. Personas portadoras nasales a partir de 4 años de edad, sin signos de enfermedad infecciosa y que no habían tomado antibióticos ni habían estado hospitalizados en los 3 meses anteriores. Se recogieron 3.969 frotis nasales válidos para identificación entre 2010 y 2011 y fueron enviados a un laboratorio central de microbiología para el aislamiento de ambos gérmenes. La resistencia a los antibióticos se estableció según los puntos de corte actuales de la guía del European Committee on Antimicrobial Susceptibility Testing. La prevalencia de S. aureus resistente a meticilina fue del 1,3% (IC 95%: 0,5-2,1%), con porcentajes de resistencia frente a fenoximetilpenicilina del 87,1% y a azitromicina del 11,6%, sin observar diferencias significativas según edad y sexo. Un 2,4% (IC 95%: 0,1-4,7%) de las cepas de neumococo fueron altamente resistentes a fenoximetilpenicilina y macrólidos, mientras que las mayores resistencias se observaron frente a cefaclor (53,3%), tetraciclina (20%) y cefuroxima (12,1%). Estos patógenos tienen resistencias más bajas en la comunidad que las que se observan en el medio hospitalario. Es importante que se conozca la resistencia antibiótica actual para poder hacer un uso más prudente de los antibióticos. The information available on antibiotic resistance patterns are generally based on specimens from hospitalised individuals. This study was aimed at evaluating the antibiotic resistance rate of nasal carriage strains of Staphylococcus aureus and Streptococcus pneumoniae in healthy individuals, in accordance with age and gender, attended in Primary Care Centres (PCC). Cross-sectional study. Seven PCC in the Barcelona area. Healthy nasal carriers aged 4 years or more who did not present with any sign of infectious disease, and had not taken any antibiotic or had been hospitalised in the previous 3 months. A total of 3,969 nasal swabs valid for identification were collected between 2010 and 2011 and were sent to one central microbiological laboratory for isolation of both pathogens. Resistance to common antibiotics was determined on the basis of the current European Committee on Antimicrobial Susceptibility Testing guidelines on cut-off points. The prevalence of methicillin-resistant S. aureus was 1.3% (95% CI: 0.5-2.1%), with resistance rates of 87.1% to phenoxymethylpenicillin and 11.6% to azithromycin, with no significant differences with age and gender. A total of 2.4% (95 CI%: 0.1-4.7%) of the pneumococcal strains were highly resistant to both phenoxymethylpenicillin and macrolides, whereas the highest resistance rates were to cefaclor (53.3%), followed by tetracycline (20%) and cefuroxime (12.1%). These pathogens have lower resistance rates in the community than in the hospital setting. Primary Care physicians must be more aware of the current antimicrobial resistance, in order to ensure prudent use of antibiotics." @default.
