简要总结
Antiphospholipid syndrome (APS) is an autoimmune disorder characterized by thrombosis and pregnancy morbidity in patients with persistently positive antiphospholipid antibodies (aPLs). However, large-scale research on general population with persistent aPLs has been lacking. This project proposes to establish the first multicenter cohort of patients with persistently positive aPLs in China and conduct a comprehensive clinical phenotyping study. Based on traditional phenotypes of thrombotic and pregnancy events, the focus will be on extra-standard clinical phenotypes and prospective assessment of event risk and prognosis in aPL-positive population. A prospective analysis of extra-standard antibodies will also be conducted to recommend detection criteria for extra-standard antibody application in China and to assess their clinical significance.
详细描述
Chinese AntiphosPholipid Syndrome cohorT cOllaborative NEtworks (CAPSTONE) is a national research network created to register patients with persistent aPLs. We aim at enrolling 2000 patients from a total of six centers, lead by the Peking Union Medical College Hospital (PUMCH). The aPLs assay will be validated in the central lab in PUMCH. All patients will be followed every six months, and up to three years. Thrombotic and pregnancy events related to aPLs will be recorded, as well as extra-criteria clinical phenotypes.
