Abstract

β2-glycoprotein I (β2GPI) is the major autoantigen in the antiphospholipid syndrome. The central importance of understanding β2GPI physiology from the perspective of the rheumatologist is that it forms the foundation for understanding the pathophysiology underlying autoantibody generation, and the diverse mechanisms by which anti-β2GPI antibodies in complex with β2GPI may predispose an individual to the antiphospholipid syndrome clinical phenotype. This review examines some of the latest novel findings in this area.

Keynote webinar | Spotlight on medication adherence

Live: Thursday 27th June 2024, 18:00-19:30 (CEST)

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
