Abstract

DM and PM were the two major subtypes in myositis; among which, a unique metabolomic and biomarker profile remains lacking. Serum from 36 diagnosed myositis patients (28 DM and 8 PM) and 29 healthy controls was analyzed using HPLC-Q-TOF-MS/MS. PLS-DA was conducted through MetaboAnalyst 5.0 to identify the differential metabolites. The KEGG analysis was utilized to observe the related metabolic pathways. The potential biomarker value was assessed using ROC analysis. The relationship between the clinical characteristics and the levels of identified differential metabolites was analyzed using R language. PLS-DA showed a clear separation between healthy controls and myositis patients, and 131 differential metabolites were identified. KEGG analysis uncovered multiple disturbed metabolic pathways. Besides, nine differential metabolites were identified between PM and DM patients, which were involved in pentose and glucuronate interconversions. ROC curve analysis revealed the AUC of these identified metabolites is above 0.7. Among them, indoxyl sulfate, oleamide, and palmitoylethanolamide presented moderate or strong correlation with clinical characteristics. Metabolomics presents a different spectrum between myositis patients and healthy controls, PM and DM patients. Besides, indoxyl sulfate, oleamide, and palmitoylethanolamide may be potential biomarkers in distinguishing PM from DM.

期刊介绍： Biomedical Chromatography is devoted to the publication of original papers on the applications of chromatography and allied techniques in the biological and medical sciences. Research papers and review articles cover the methods and techniques relevant to the separation, identification and determination of substances in biochemistry, biotechnology, molecular biology, cell biology, clinical chemistry, pharmacology and related disciplines. These include the analysis of body fluids, cells and tissues, purification of biologically important compounds, pharmaco-kinetics and sequencing methods using HPLC, GC, HPLC-MS, TLC, paper chromatography, affinity chromatography, gel filtration, electrophoresis and related techniques.
