Hypoglycemia in type 2 diabetes mellitus (T2DM) has been associated with metabolic abnormalities and inflammation affecting multiple vascular beds. To clarify its relationship with panvascular disease (PVD), investigators conducted a retrospective cross-sectional study across two centers in Chongqing, China, with external validation using UK Biobank data. The results were published in the Diabetes & Vascular Disease Research.

The analysis included 22,128 patients with T2DM from two large centers and 44,442 T2DM participants from the UK Biobank. Logistic regression demonstrated a significant association between hypoglycemia and PVD. Stratified and interaction analyses showed that the association was stronger among patients with inflammatory abnormalities and metabolic dysfunction.

Structural equation modeling (SEM) was used to examine forward (hypoglycemia to PVD) and reverse (PVD to hypoglycemia) pathways, incorporating interleukin-6, neutrophil-to-lymphocyte ratio, uric acid, hemoglobin A1c, and systolic blood pressure. SEM suggested a correlation structure in which hypoglycemia and PVD may mutually aggravate each other through inflammatory and metabolic pathways.

The cross-sectional design precludes determination of temporal sequence or causality. The retrospective dataset included selected inflammatory and metabolic markers, and SEM-identified pathways reflect correlations requiring further validation.

Hypoglycemia and panvascular disease were significantly associated in large T2DM populations, with inflammation and metabolism identified as potential mediators. Further clinical and mechanistic studies are needed to clarify causal pathways and broader mediating factors.
