Clinical, biochemical, and epigenetic profiling in children with Behçet disease

Clinical, Biochemical and Epigenetic Profile of Pediatric Behçet Disease: Similarities and Differences From Adult Patients and Looking for Potential Biomarkers.

Not applicable Interventional Meyer Children's Hospital IRCCS · NCT07375940

This project will test whether blood-based clinical, genetic, and epigenetic markers can identify biologically distinct subgroups of children with Behçet disease.

What this trial studies

This is a prospective, multicenter case-control effort enrolling pediatric Behçet patients, adult Behçet patients, and healthy pediatric controls with longitudinal clinical data and blood sampling at diagnosis, remission, and flare. The study measures circulating cytokines, microRNA profiles, genome-wide DNA methylation, and targeted genetic variants linked to monogenic autoinflammatory conditions. By integrating these multi-omic data with clinical features, the investigators aim to define meaningful patient subgroups and improve disease stratification. Findings will be compared with adult BD profiles to highlight pediatric-specific signatures.

Who should consider this trial

Good fit: Ideal participants are children and adolescents with a confirmed Behçet diagnosis (per ICBD, ISG, or PEDBD criteria) who can provide consent/assent, plus matched healthy pediatric controls for comparison.

Not a fit: Patients without Behçet disease, those with an alternative unexcluded diagnosis, or those unwilling/unable to provide informed consent are unlikely to receive direct benefit from participation.

Why it matters

Potential benefit: If successful, the work could help doctors classify children with Behçet disease into biologically distinct groups to improve prognosis and guide more personalized treatment choices.

How similar studies have performed: Biomarker studies in adults with Behçet disease have reported altered cytokine, microRNA, and DNA methylation patterns, but comparable multimodal profiling in pediatric populations is limited and largely untested.
