Serum metabolites were analyzed using gas chromatography-mass spectrometry (GC-MS). Multivariate analysis was used to identify differential metabolites, and pathway enrichment analysis was performed to explore their biological significance. <i>Results.</i> A total of 61 patients were enrolled, comprising 18 in the ISR group and 43 in the non-ISR group. The ISR group demonstrated a higher prevalence of smoking (50% vs. 21%, <i>p</i> = 0.023), a greater incidence of previous myocardial infarction (72% vs. 37%, <i>p</i> = 0.004), and a lower left ventricular ejection fraction (51% vs. 58%, <i>p</i> = 0.004) compared to the non-ISR group. Seven differential metabolites were identified, with five being upregulated (inosine, myo-inositol, 3-cyanoalanine, monostearin, and glutamine) and two downregulated (biuret and 3-methylcatechol). Pathway enrichment analysis revealed three major metabolic pathways associated with ISR: inositol phosphate metabolism, alanine-aspartate-glutamate metabolism, and the phosphatidylinositol signaling system. Receiver operating characteristic (ROC) analysis indicated that inosine had the highest diagnostic performance [The area under the curve (AUC) = 0.807], followed by myo-inositol (AUC = 0.705) and monostearin (AUC = 0.643). The combined biomarker panel significantly enhanced diagnostic accuracy, achieving an AUC of 0.925, indicating strong predictive potential for ISR. <i>Conclusions.</i> This study identified seven potential serum biomarkers and three metabolic pathways linked to ISR.

There are some data on genomic biomarkers reflecting inflammation and extracellular matrix remodelling in HTAD. However, data that accurately reflect the corresponding protein changes are scarce. Our aim was to quantify proteins by using targeted proteomics in HTAD patients versus healthy controls, to better understand the underlying pathophysiology. <i>Methods</i>. Patients with Loeys-Dietz syndrome (LDS, <i>n</i> = 8), Marfan syndrome (MFS, <i>n</i> = 11), and familial TAA 6, i.e. actin alpha 2 (ACTA2, <i>n</i> = 7) pathogenic variants were recruited at our outpatient clinic. For comparison, blood samples were drawn from 16 healthy controls. Plasma samples were analysed by targeted proteome analysis of 276 proteins using immunoaffinity proteomics. <i>Results</i>. Whereas oncostatin M and pentraxin 3 levels appeared generally higher in HTAD patients, after adjusting for several confounders, significantly higher levels for these markers as well as TNF receptor superfamily member 9 (TNFRSF9), granulysin (GNLY), CD5, vasorin and glycoprotein 1b-α (GP1BA) were only observed in LDS patients compared to healthy controls. Levels of TNFRSF9, GNLY, GP1BA and CD5 correlated positively with Th17 and platelet counts. <i>Conclusions</i>. This discovery study suggests that LDS could represent a particular inflammatory subgroup of HTAD patients potentially reflecting the involvement of Th17 and platelet related mechanisms in the progression of TAA.
