| dc.description.abstract | Las altas concentraciones posprandiales de quilomicrones y sus remanentes se correlacionan con una progresión de la aterosclerosis. La apolipoproteína B-48 es un componente esencial de estas lipoproteínas y parece ser un marcador adecuado para los estudios clínicos del metabolismo lipídico posprandial y su relación con el riesgo cardiovascular. Se desarrolló un ELISA de doble sándwich para la cuantificación rutinaria de Apo B-48 en plasma humano no tratado. Se describió el comportamiento posprandial de Apo B-48 en individuos jóvenes sanos empleando el método y las correlaciones entre la Apo B-48 plasmática y los parámetros lipídicos y clínicos. Se desarrolló un anticuerpo policlonal dirigido contra el extremo carboxi-terminal de Apo B-48, y se prepararon los calibradores apropiados usando una columna de afinidad a la que se unió el anticuerpo desarrollado. Se usó un anticuerpo monoclonal de ratón capaz de reconocer tanto Apo B-48 como Apo B-100 como segundo anticuerpo, y como tercer anticuerpo se usó una IgG anti-ratón acoplada a enzima. Los niveles plasmáticos de Apo B-48 se determinaron en 42 individuos jóvenes sanos de ambos sexos en ayunas y cada hora después del consumo de un desayuno con 40 g de grasa. La técnica mostró una variación intraensayo de 3,0-3,8%. La Apo B-48 plasmática fluctuó entre 0,5 y 0,8 mg / L en ayunas, con un incremento horario hasta alcanzar un máximo entre 4,6 y 8,4 mg / L en la tercera hora posprandial. El área bajo la curva de Apo B-48 posprandial y la Apo B-48 de la tercera hora mostraron una fuerte correlación con el índice de masa corporal (r = 0,58 y 0,8 respectivamente). Este artículo presenta un ensayo novedoso que hace que la cuantificación de Apo B-48 sea más fácil y rápida con la precisión adecuada y sin requisitos para el procesamiento de muestras. La Apo B-48 plasmática en individuos jóvenes sanos mostró una cinética posprandial caracterizada por concentraciones bajas en ayunas que aumentan hasta un pico aproximadamente 3 horas después de una comida y vuelven a valores bajos después de 6 horas.

| dc.description.abstractenglish | High postprandial concentrations of chylomicrons and its remnants are correlated with an atherosclerosis progression. Apolipoprotein B-48 is an essential component of these lipoproteins and appears to be a suitable marker for clinical studies of postprandial lipid meta-bolism and its relationship to cardiovascular risk. A double-sandwich ELISA was developed for routine Apo B-48 quantification in untreated human plasma. The postprandial behavior of Apo B-48 in healthy young individuals was described employing the method, and corre-lations between plasma Apo B-48 and lipid and clinical parameters. A polyclonal antibody directed against the carboxy-terminal extreme of Apo B-48 was developed, and appropriate calibrators were pre-pared using an affinity column to which the developed antibody was attached. A mouse monoclonal antibody able to recognize both Apo B-48 and Apo B-100 was used as second antibody, and an enzyme-coupled anti-mouse IgG was used as third antibody. The plasma Apo B-48 levels were determined in 42 healthy young individuals of both sexes in the fasting state and hourly after the consumption of a breakfast with 40 g fat. The technique showed an intra-assay variation of 3,0-3,8%. Plasma Apo B-48 fluctuated between 0,5 and 0,8 mg/L in the fasting state, with an hourly increase to reach a maximum between 4,6 and 8,4 mg/L at the third postprandial hour. The postprandial Apo B-48 area under curve and third hour Apo B-48 showed a strong correlation with body mass index (r=0,58 and 0,8 respectively). This paper presents a novel assay that makes Apo B-48 quantification easier and faster with adequate precision and without requirements for sample processing. Plasma Apo B-48 in healthy young individuals showed postprandial kinetics characteri-zed by low fasting concentrations that increase to a peak about 3 hours after a meal and return to low values after 6 hours.
