ABSTRACT

La ateroesclerosis comienza en etapas tempranas de la vida y la disfunción endotelial se reconoce como el acontecimiento inicial dominante en su desarrollo. Estudiar marcadores de inflamación y disfunción endotelial en niños con infección bacteriana. Se estudiaron 36 niños (6 meses-10 años 11 meses) hospitalizados con diagnóstico de infección bacteriana. Se tomó sangre venosa en tres fases: I (fase aguda infección, ingreso), II (convalecencia, 1 semana post-admisión), III (recuperación, 1 mes postadmisión). 32 niños sanos de la consulta. En todos los pacientes y controles se determinó: colesterol total y fracciones, triglicéridos, proteínas totales y fraccionadas, PCR ultrasensible (PCRus), sICAM-1, sVCAM-1, IL-6, óxido nítrico. En los niños con infección se encontró: 1) niveles de colesterol total elevados: aumento en las fracciones de LDL-C y LP(a)- C en la fase I con el pico en fase II y disminución con la recuperación del niño, 2) aumento del perfil inflamatorio mediado por IL-6, con el subsecuente aumento de la PCRus y alfa 2 globulinas, las cuales disminuyen en la fase de recuperación. Los marcadores de disfunción endotelial sVCAM-1 e sICAM-1 aumentan en la fase I y disminuyen con la recuperación. Los marcadores de inflamación (IL-6, PCRus) mantienen correlación positiva con los marcadores de disfunción endotelial (sVCAM-1 e sICAM-1). Los niveles de óxido nítrico estuvieron disminuidos en las tres fases. La infección aguda bacteriana en la niñez se asocia al aumento de los marcadores inflamatorios, lo cual apoya el papel potencial de éstos en la patogénesis de la ateroesclerosis temprana


Markers of inflammation and endothelial dysfunction in children with bacterial infections. Atherosclerosis begins early in life and endothelial dysfunction is recognized as the key initiating event in the development of atherosclerosis. To study biomarkers of inflammation and endothelial dysfunction in children with bacterial infection. The study included 36 children (6 months-10 years 11 months) hospitalized with the diagnosis of bacterial infection. Venous blood was extracted in three phases: I (acute phase of infection, entry), II (convalescence, 1 week post-admission), III (recovery, 1 month post-admission). 32 children who attended the healthy children outpatient clinic were the control group. The following parameters were assessed in all patients and controls: cholesterol and its fractions, triglycerides, total and fractionated proteins, high sensitivity C-reactive protein (hsCRP), sICAM-1, sVCAM-1, IL-6, nitric oxide. Children with infection had high total cholesterol levels with increased LDL-C and Lp (a)-C fractions in phase I, rising to a peak in phase II and decreasing as the child recovers. Infected children also had an increased inflammatory profile mediated by IL-6, with the subsequent increase in hsCRP and alpha 2 globulin, which decrease as the child recovers. Endothelial dysfunction markers sVCAM-1 and sICAM-1 increase at admission and decrease as the child recovers. Inflammation markers (IL-6, hsCRP) correlate positively with markers of endothelial dysfunction (sVCAM-1 and sICAM-1). Nitric oxide levels are decreased in all three phases. Acute infection in childhood is associated with damage to the endothelium. These results support the potential role of inflammatory stimuli in the pathogenesis of early atherosclerosis
