RESUMO

La enfermedad por arañazo de gato (EAG) es producida por Bartonella henselae.Afecta principalmente a ninos y el reservorio es el gato doméstico. El diagnóstico de laboratorio se basa en la detección de anticuerpos por inmunofluorescencia indirecta (IFI). El objetivo de este trabajo fue analizar la evidencia serológica de infección por B. henselae en pacientes pediátricos que reunían criterios clínicos/epidemiológicos para la sospecha de EAG. Se estudió a 92 pacientes; de acuerdo con los resultados serológicos, estos fueron categorizados en 4 grupos: 1) IgG (+)/IgM (+), 31,5% (n = 29);2) IgG (-)/IgM (+), 10,9% (n = 10);3) IgG (+)/IgM (-), 9,8% (n = 9), y 4) IgG (-)/IgM (-), 47,8% (n = 44). La divulgación de estos resultados intenta promover futuros trabajos que investiguen la seroprevalencia de Bartonella spp. en Argentina. Esto permitirá conocer la importancia de esta zoonosis en nuestra población y evaluar nuevos puntos de corte para esta técnica serológica.


Cat scratch disease (CSD) is caused by Bartonella henselae, which mainly affects children. The cat is the reservoir. The laboratory diagnosis is based on the detection of antibodies by the Indirect Immunofluorescence (IFI) assay. The objective of this study was to analyze the serological evidence of B. henselae infection in pediatric patients that met the clini-cal/epidemiological criteria for suspected CSD. We studied 92 patients, who were categorized into four serological groups: 1) IgG (+)/IgM(+), 31,5% (n = 29); 2) IgG (-)/IgM(+), 10,9% (n = 10); 3) IgG (+)/IgM(-), 9,8% (n = 9); 4) IgG (-)/IgM(-), 47,8% (n = 44). These findings aim to promote future works for investigating the seroprevalence of Bartonella spp. in Argentina, which will allow us to know the importance of this zoonosis in our population and to evaluate new cut-off points of the technique.
