Implication

No practice change indicated for endothelial assessment in diabetes; leaves open causal roles and need for prospective validation of these phospholipids.

Key Points

To identify specific circulating plasma lipid species associated with endothelial function, measured via flow-mediated vasodilation (FMD), in individuals with type 2 diabetes.
Conducted a cross-sectional subanalysis of a lipidomic cohort including 200 patients with type 2 diabetes (55.0% men; mean age: 61.1 ± 11.3 years; mean HbA1c: 9.04 ± 1.79%; mean FMD: 5.77 ± 2.55%).
Identified and quantified 349 lipids across 16 classes using supercritical fluid chromatography/mass spectrometry-based semi-targeted lipidomic profiling.
Selected candidate lipids correlated with FMD using sparse-group least absolute shrinkage and selection operator (LASSO) regularized regression adjusting for atherosclerotic risk factors.
Screened 349 lipid species and isolated 13 distinctive candidate lipids potentially associated with FMD via sparse-group LASSO.
Identified seven phospholipids—including three phosphatidylethanolamine (PE) plasmalogens and three phosphatidylinositols (PIs)—that demonstrated significant positive associations with FMD after adjusting for traditional atherosclerotic risk factors.

Are specific plasma lipid species associated with flow-mediated vasodilation in patients with type 2 diabetes?

Population

200 patients with type 2 diabetes (mean age 61.1 years, 45% female) evaluated for associations between plasma lipids and flow-mediated vasodilation.

Exposure

Plasma lipid species profiling via supercritical fluid chromatography/mass spectrometry-based semi-targeted lipidomic analysis

Outcome

Association of plasma lipids with flow-mediated vasodilation (FMD)surrogate

Specific phospholipids, including PE plasmalogens and PIs, are positively associated with endothelial function in patients with type 2 diabetes, suggesting potential new biomarkers or targets for endothelial dysfunction.

Taya et al. (2026) conducted a cross-sectional in Type 2 diabetes (n=200). Plasma lipids was evaluated on Association with flow-mediated vasodilation (FMD). Seven specific plasma phospholipids, including three phosphatidylethanolamine plasmalogens and three phosphatidylinositols, were positively associated with flow-mediated vasodilation.
