This prospective multicenter study collects blood samples and clinical data from pediatric and adult Behçet disease patients and healthy pediatric controls. It compares cytokine levels, circulating microRNA, genome-wide DNA methylation, and targeted genetic variants. The goal is to define molecular patterns and patient subgroups in pediatric Behçet disease.
What it is studying. Whether clinical and multi-omic (cytokine, microRNA, DNA methylation, and genetic) profiles differ between pediatric and adult Behçet disease and compared with healthy pediatric controls, and whether these molecular signatures can define patient subgroups or associate with disease stages.
What the researchers hope to learn. To identify disease-associated molecular signatures (cytokine patterns, circulating microRNA, DNA methylation profiles, and genetic variants), characterize biologically meaningful patient subgroups, and explore biomarkers linked to disease activity and remission to inform future research into diagnosis and treatment strategies.
What this study is about
The study's own summary, as published on ClinicalTrials.gov. Underlined terms have a short explanation.
Behçet disease (BD) is a chronic multisystem inflammatory disorder with a relapsing-remitting course. Pediatric-onset BD is rare and characterized by marked clinical heterogeneity, frequent incomplete presentation at disease onset, and limited availability of pediatric-specific outcome measures and biomarkers. This prospective multicenter study aims to comprehensively characterize the clinical, biochemical, genetic, and epigenetic profiles of pediatric patients with Behçet disease and to compare them with adult BD patients and healthy pediatric controls. The study focuses on the identification of disease-associated cytokine patterns, circulating microRNA profiles, DNA methylation signatures, and genetic variants associated with monogenic autoinflammatory diseases presenting with a Behçet-like phenotype. By integrating clinical data with multi-omic analyses, this study seeks to identify biologically and clinically meaningful patient subgroups, improve disease stratification, and explore potential biomarkers of disease activity and remission in pediatric Behçet disease.

Study description and what participation involves
The study's detailed description, as published on ClinicalTrials.gov.
Show the detailed description from the registry
Behçet disease is a chronic inflammatory disorder involving mucocutaneous, ocular, vascular, neurological, gastrointestinal, and musculoskeletal systems. Although the clinical manifestations of pediatric BD are largely similar to those observed in adults, pediatric cases show greater heterogeneity, higher familial aggregation, and frequent diagnostic uncertainty, particularly at early disease stages. The etiopathogenesis of BD remains incompletely understood and is thought to involve a complex interaction between genetic predisposition, immune dysregulation, environmental triggers, and epigenetic mechanisms. Increased levels of pro-inflammatory cytokines, including interleukin (IL)-6, IL-17, and tumor necrosis factor alpha (TNF-α), as well as altered circulating microRNA and DNA methylation profiles, have been reported in adult BD patients, but data in pediatric populations are scarce. This prospective, multicenter, case-control study will enroll pediatric and adult patients with Behçet disease and healthy pediatric controls. Clinical data will be collected longitudinally, and biological samples will be obtained during routine blood draws at predefined disease stages, including diagnosis, sustained remission, and disease flare. The study will evaluate circulating cytokine levels, genome-wide DNA methylation profiles, circulating microRNAs, and genetic variants associated with monogenic autoinflammatory diseases that can mimic BD. Pediatric healthy controls will provide reference epigenetic and microRNA profiles for comparative analyses. Through integrated clinical and molecular analyses, this study aims to identify disease-associated molecular signatures, characterize patient subgroups, and improve understanding of pediatric Behçet disease pathogenesis, potentially supporting future development of personalized diagnostic and therapeutic strategies.

Participants will have clinical information collected over time and provide blood samples taken during routine clinical visits. Blood samples will be used for research tests such as cytokine profiling, circulating microRNA analysis, DNA methylation profiling, and targeted genetic sequencing for Behçet patients; healthy pediatric controls will have microRNA and DNA methylation analyses only and will not undergo genetic sequencing. Research analyses are for study purposes and will not be used for clinical decision‑making. Follow-up and sample collection may occur at predefined stages (diagnosis, sustained remission, and disease flare) over a period up to 24 months.
How the study is structured. Interventional, non-randomized, parallel study that collects blood samples during routine clinic visits at predefined disease stages (diagnosis, remission, flare). Samples undergo laboratory analyses for cytokines, circulating microRNA, DNA methylation and targeted genetic testing. The study is not masked.
