BACKGROUND: Synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome is a rare disease that is characterized by autoinflammatory lesions on both bones and skin. The diverse manifestations and limited understanding of its etiology have hindered the diagnosis and treatment of this condition. SAPHO syndrome is also classified as a primary inflammatory osteitis. The onset of osteoarticular involvement in this disease is typically gradual, and the identification of associated biomarkers may be crucial for accurate diagnosis, effective treatment, and a better understanding of its underlying mechanisms.
METHODS: We enrolled a total of 6 SAPHO patients and 3 healthy volunteers for this study. The miRNA expression profile in circulating exosomes was analyzed using next-generation sequencing. A total of 45 miRNAs were found to be differentially expressed in SAPHO patients. Linear discriminant analysis effect size analysis and Wilcoxon rank-sum test were employed to identify biomarkers based on these differentially expressed miRNAs. Among them, we selected 4 miRNAs as biomarkers for SAPHO syndrome, resulting in an area under the receiver operating characteristic curve of 1.
RESULTS: The differentially expressed miRNAs indicated enrichment in immune system and endocrine system-related KEGG pathways, as well as infectious diseases and cancers. Furthermore, the most significantly enriched molecular functions in GO analysis were protein binding and catalytic activity.
CONCLUSION: The exosomal miRNA profile in SAPHO syndrome exhibited significant changes, suggesting its potential as a candidate biomarker for diagnostic assistance, although further investigation is warranted to elucidate their role in the pathology.
