RESUMEN
Introducción: la preeclampsia tiene una incidencia de aproximadamente 5% en la población obstétrica. La fisiopatología de esta entidad tiene como característica fundamental la disfunción endotelial y la activación plaquetaria. Las selectinas son moléculas que regulan la interacción de éstas. La P-selectina se expresa en la superficie de la plaqueta. El objetivo es describir el papel de la P-selectina en la reactividad endotelial en pacientes con preeclampsia y compararlo con pacientes con embarazo normal.
Material y métodos: estudio de casos y controles. Fueron seleccionadas 30 pacientes con preeclampsia severa (casos) que recibieron atención en la Unidad de Cuidados Intensivos y se contrastaron con 30 pacientes con embarazo sin patología concomitante (controles), de la Unidad de Tococirugía del mismo hospital. A todas las mujeres, previo consentimiento informado, se les tomaron 10 ml de sangre periférica y se determinó la P-selectina mediante la técnica ELISA, con un kit Bender Med.
Resultados: se compararon las principales variables clínicas, bioquímicas y hematológicas, resaltando la diferencia significativa respecto a P-selectina.
Conclusiones: la P-selectina es un marcador de la reactividad endotelial en pacientes con preeclampsia severa.
