Abstract
Objectives: Primary Sjögren's disease (SjD) is a slow-progressing autoimmune disease that affects salivary and lacrimal glands, causing dry eyes (xerophthalmia) and dry mouth (xerostomia). Diagnosing SjD involves clinical, serological, and histological assessments, but reliable biomarkers are lacking.
Methods: This study analyzed the metabolic and proteomic profiles of 19 female SjD patients (based on ACR-EULAR criteria) compared to 20 healthy individuals. Saliva and blood samples were analyzed using mass spectrometry and chromatography. Proteomic analysis was performed with the nanoElute nanoflow system coupled to a timsTof-Pro mass spectrometer, and metabolic profiling with a GC-TOF/MS Pegasus HT.
Results: Statistical tests identified significant differences in metabolites and proteins between SjD patients and controls. Metabolome analysis revealed changes in amino acid synthesis, purine and lipid metabolism, and exposure to external compounds. Proteomic analysis indicated immune-related proteins and inflammatory lipid metabolism. GNAI2, B2MG, NGAL, SLUR2, HS90, SODC, and A2GL emerged as potential biomarkers for SjD.
Conclusion: This study demonstrates the potential of high-performance techniques in identifying biomarkers for SjD diagnosis and prognosis. Data are available via ProteomeXchange (PXD055629).
期刊介绍:
Oral Diseases is a multidisciplinary and international journal with a focus on head and neck disorders, edited by leaders in the field, Professor Giovanni Lodi (Editor-in-Chief, Milan, Italy), Professor Stefano Petti (Deputy Editor, Rome, Italy) and Associate Professor Gulshan Sunavala-Dossabhoy (Deputy Editor, Shreveport, LA, USA). The journal is pre-eminent in oral medicine. Oral Diseases specifically strives to link often-isolated areas of dentistry and medicine through broad-based scholarship that includes well-designed and controlled clinical research, analytical epidemiology, and the translation of basic science in pre-clinical studies. The journal typically publishes articles relevant to many related medical specialties including especially dermatology, gastroenterology, hematology, immunology, infectious diseases, neuropsychiatry, oncology and otolaryngology. The essential requirement is that all submitted research is hypothesis-driven, with significant positive and negative results both welcomed. Equal publication emphasis is placed on etiology, pathogenesis, diagnosis, prevention and treatment.
