Is this trial a fit for you?

Likely a good fit

Adults diagnosed with ankylosing spondylitis or axial psoriatic arthritis who are willing to provide a blood sample.

Probably not a fit

Patients with other autoimmune diseases or major organ dysfunction, or those taking certain drugs, may not benefit from this study's findings.

What this trial studies

This observational study analyzes blood samples to measure glutathione peroxidase 4 (GPX4) levels in patients with ankylosing spondylitis or axial psoriatic arthritis. It aims to explore how GPX4 relates to disease activity and severity. The background considers ferroptosis, a form of iron-dependent cell death linked to lipid peroxidation and oxidative stress, and how this process may interact with immune function and autoimmunity in spondyloarthropathies. Participants are adults diagnosed by ASAS or CASPAR criteria, with exclusions for other autoimmune diseases and major organ dysfunction. The lead sponsor is Assiut University, with the study based at the Faculty of Medicine, Assiut University in Asyut.

Why it matters

Potential benefit: If GPX4 is linked to disease activity, this could guide future biomarkers or therapies for spondyloarthropathies.

How similar studies have gone: Previous research has begun to link ferroptosis pathways with autoimmune diseases, but this specific GPX4-blood level association in these conditions is exploratory.
