Evaluation of Serum Soluble Lectin-like Oxidised Low-Density Lipoprotein Receptor-1 (sLOX-1) Level in Children with Non-Complicated Type-1 Diabetes Mellitus (T1DM) and Its Relationship with Carotid Intima Media Thickness (cIMT)

TL;DR

This study found that children with type-1 diabetes have higher levels of a protein linked to early artery damage, even before complications arise.

Contribution

The study is the first to show a strong link between sLOX-1 levels and early atherosclerosis in children with uncomplicated T1DM.

Findings

Children with T1DM had significantly higher sLOX-1 levels than healthy controls.

sLOX-1 levels strongly correlated with carotid intima-media thickness, a marker of early atherosclerosis.

A cutoff of 0.65 ng/mL for sLOX-1 was associated with T1DM.

Abstract

Background: The objective of this study was to evaluate serum soluble lectin-like oxidized low-density lipoprotein receptor-1 (sLOX-1) levels in children with type-1 diabetes mellitus (T1DM) without any atherosclerotic complications and to investigate whether there was an association with early atherosclerotic processes in these children. Methods: The study’s design entailed a prospective cross-sectional observational study methodology. The patient group consisted of 80 consecutive children aged 8–18 years who had been diagnosed with T1DM for at least ten years and had not developed any chronic clinical complications related to T1DM. The control group consisted of 72 completely healthy children with similar demographic characteristics. Serum levels of sLOX-1 were measured, and carotid intima-media thickness (cIMT) was evaluated using ultrasonography in all subjects. Results: A statistical analysis of the results was conducted. The serum sLOX-1 level was found to be significantly higher in the patient group than in the control group (0.49 ± 0.11 vs. 0.82 ± 0.35; p < 0.001). The statistical significance observed was maintained in the multivariable logistic regression analysis (p < 0.001). A significant correlation was identified between cIMT and serum sLOX-1 levels (r = 0.669, p < 0.001). The receiver operating characteristic curve for sLOX-1 indicated that a cutoff value greater than 0.65 ng/mL was associated with T1DM. Conclusions: Serum sLOX-1 levels were markedly elevated in children with T1DM who had not yet manifested chronic complications. These findings suggest that elevated serum sLOX-1 levels may be associated with the progression of atherosclerosis in children with T1DM.
