Analysis of glycosylation in lupus anti-DNA antibodies

Glycosylation Analysis of Anti-DNA Auto-antibodies as Biomarker in the Follow up of Patients With Lupus Erythematosus Disseminated (GALA)

Observational University Hospital, Montpellier · NCT05394922

This study looks at how certain sugars on antibodies in people with lupus might change over time and how those changes relate to their disease activity.

What this trial studies

This observational study aims to analyze the glycosylation patterns of anti-DNA antibodies in patients with systemic lupus erythematosus (SLE). A total of 140 adult patients will be recruited from the University Hospital of Montpellier and Nîmes, and followed for one year. Blood samples will be collected at the start, after one year, and during any disease flare, with serum stored for analysis. The glycosylation status of the antibodies will be determined using mass spectrometry and correlated with disease activity measured by the SLEDAI score.

Who should consider this trial

Good fit: Ideal candidates are adults diagnosed with systemic lupus erythematosus who have positive native anti-DNA antibodies.

Not a fit: Patients who are unable to provide informed consent or are involved in other interventional studies may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved biomarkers for monitoring disease activity in lupus patients.

How similar studies have performed: While glycosylation analysis in antibodies is a recognized area of research, this specific approach in lupus has not been extensively tested, making it a novel investigation.
