Avidita antifosfolipidových protilátek – naše současné znalosti

Antifosfolipidové protilátky (APL), které představují sérový marker antifosfolipidového syndromu, zahrnují mimořádně heterogenní skupinu protilátek namířených proti různým fosfolipidům a proteinovým kofaktorům. Heterogenita APL se týká nejen specifity vazebných míst, ale také jejich avidity. Cílem studie bylo shrnout dosavadní znalosti o běžně užívaných postupech pro stanovení avidity se speciálním zaměřením na APL a zhodnocení jejího klinického významu. Často užívanou technikou pro stanovení avidity protilátek jsou ELISA metody v přítomnosti různých chaotropních látek. Nálezy klinických studií ukazují, že APL o vysoké aviditě se vyskytují u pacientů s trombózou a antifosfolipidovým syndromem (APS). Vyšetření avidity APL by mohlo být doplňujícím laboratorním ukazatelem, který by přinesl informaci využitelnou pro klasifikaci APS.
