Síndrome anti-PEG: el impacto de la biotecnología en las inmunotrombosis

Abstract

El síndrome anti-PEG es una reacción adversa inmunotrombótica que cursa con la activación del complemento y que está mediada por anticuerpos anti-PEG, los cuales han sido generados previamente por el uso de formulaciones farmacéuticas con compuestos polietoxilados como el polietilenglicol (PEG) y los polisorbatos, entre otros. Su emergencia actual radica en la alta prevalencia de anticuerpos anti-PEG en la población motivada por el auge de la biotecnología, y en que dichos anticuerpos exiben una reactividad de doble naturaleza: Reactividad sintética: los anticuerpos anti-PEG son capaces de reaccionar con las estructuras polietoxiladas de los mismos compuestos químicos de amplio uso que los generan, lo que provoca diversos efectos adversos trombóticos. Reactividad biológica: los anticuerpos anti-PEG son capaces de establecer una reacción cruzada con las glicoproteínas manosiladas de la superficie de diversos microorganismos, lo que conduce a COVID-19 grave y otras formas de inmunotrombosis infecciosa. El síndrome anti-PEG puede manifestarse en un amplio rango temporal tras el primer contacto antigénico, lo que puede dificultar la identificación de su etiología inmunológica.
