Background: Behçet’s disease is a systemic, inflammatory disease affecting multiple organs. Vascular involvement is the main cause of morbidity and mortality in Behçet’s disease patients. Though clinically well-defined, there is limited information related to disease pathogenesis and vascular incidence in this patient group. The aim of this study is to investigate the unique metabolic signatures of Behçet’s disease patients with vascular involvement.
Methods: Metabolomic profiling was performed on serum samples of 48 Behçet’s disease patients (18 with vascular involvement) and 40 healthy controls using gas chromatography-mass spectrometrybased untargeted metabolomics analysis. Multivariate and univariate statistical analyses were performed to find altered metabolites and pathways.
Results: Untargeted metabolomics results showed that a total of 168 metabolites were identified. The comparison between the groups of Behçet’s disease, vascular involvement in Behçet’s disease, and the healthy control group showed that altered amino acid and oxidative stress pathways, especially with glutathione synthesis, could be an important stage for developing Behçet’s disease.
Conclusion: In the present work, the untargeted metabolomics approach provided new molecular insights for a better understanding of Behçet’s disease pathogenesis and also developing vascular involvement in Behçet’s disease at the metabolite level. The results showed that vascular involvement in Behçet’s disease could be highly linked with amino acid metabolism and also the antioxidant system, and these disease-related pathways could be evaluated with further experiments for diagnosis and prognosis of Behçet’s disease and also for vascular involvement in Behçet’s disease.
