What this trial studies

This project aims to establish the first multicenter cohort of patients in China with persistently positive antiphospholipid antibodies (aPLs) to better understand antiphospholipid syndrome (APS). The study will enroll 2000 patients from six centers, led by Peking Union Medical College Hospital, and will focus on comprehensive clinical phenotyping, including thrombotic and pregnancy events. Patients will be followed every six months for up to three years to assess event risk and prognosis, as well as the clinical significance of extra-standard antibodies. The findings may help refine detection criteria for aPLs in the Chinese population.

Who should consider this trial

Good fit: Ideal candidates are individuals with one or more antiphospholipid antibodies present on two or more occasions at least 12 weeks apart.

Not a fit: Patients who refuse to participate or are unable to be followed will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnosis and management of antiphospholipid syndrome in patients with persistent aPLs.

How similar studies have performed: While there have been studies on antiphospholipid syndrome, this cohort approach in China is novel and aims to fill a significant gap in large-scale research.
