Antiphospholipid syndrome in people 65 and older who had an ischemic stroke

Official title: A Prospective, Single-center Cohort Study to Determine the Prevalence and Consequences of Antiphospholipid Syndrome in Patients Aged 65 and Over With Ischemic Strokes (IS)

Run by CHU de Reims · NCT07163338 · Data updated 2026-11-12

This study will test whether routine blood testing for antiphospholipid antibodies in people aged 65 and over hospitalized with ischemic stroke or TIA can identify previously unrecognized antiphospholipid syndrome.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are people aged 65 or older who are hospitalized for ischemic stroke or TIA, able to provide consent, and registered with the social security system.

Probably not a fit

Patients whose stroke cause is clearly explained by other factors (for example atrial fibrillation or advanced atherosclerosis) or who cannot undergo testing or long-term anticoagulation are less likely to gain direct benefit from this screening.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The study will enroll patients aged 65 and older who are hospitalized for ischemic stroke or transient ischemic attack and collect blood samples for antiphospholipid antibody testing (anti-cardiolipin, anti-β2-glycoprotein I, and lupus anticoagulant). Researchers will determine the prevalence of positive antibody results in this older population and relate antibody presence to clinical features, stroke etiology, and short-term outcomes. Collected biological data will be compared with patients' clinical records to explore associations with arterial thrombosis and risk factors. Findings aim to inform whether routine screening in this age group uncovers treatable causes that change secondary prevention.

Why it matters

Potential benefit: If successful, the study could uncover previously unrecognized antiphospholipid syndrome in older stroke patients, which may lead to changes in long-term anticoagulation and potentially reduce recurrent thrombosis risk.

How similar studies have gone: Prior work shows antiphospholipid syndrome explains a notable share of ischemic strokes in younger patients, but systematic data and outcomes for routine screening in people aged 65 and over are limited.
