Intrahepatic lipid content is independently associated with soluble E-selectin levels: The Maastricht study.

BACKGROUND

Evidence is accumulating that liver sinusoidal endothelial cells are involved in the pathogenesis of non-alcoholic fatty liver disease. Previous studies have suggested that the endothelial biomarker soluble E-selectin (sE-selectin) is to an important extent liver-derived.

AIMS: To study the relationship of intrahepatic lipid (IHL) content with sE-selectin at the population level.

METHODS

This study was conducted in participants of The Maastricht Study (n = 1,634), a population-based cohort study enriched with patients with type 2 diabetes. We assessed the cross-sectional association between IHL content, quantified by MRI, and sE-selectin via multivariable regression with adjustment for age, sex, type 2 diabetes, educational level, BMI, Dutch Healthy Diet index, physical activity, and the Matsuda index.

RESULTS

Standardized IHL content was associated with (log) sE-selectin (age-, sex- and type 2 diabetes-adjusted regression coefficient [B]: 0.048 [95%CI:0.038;0.058], p<0.001), even after full adjustment (B: 0.030 [0.019;0.042], p<0.001). Such an association was not observed for soluble vascular cell adhesion molecule 1 (sVCAM-1) levels.

CONCLUSION

IHL content is an independent determinant of sE-selectin at the population level. These findings support further studies to unravel the involvement of liver sinusoidal endothelial cells in the different stages of non-alcoholic fatty liver disease and the specific role of E-selectin herein.
