Key result
HDL protects against abdominal aortic aneurysm (OR=0.600), with IL-10 mediating 4.38% of this effect, whereas LDL (OR=1.940) and triglycerides (OR=1.536) increase risk.
Why the study?
Do inflammatory factors mediate the causal effect of lipid levels on the risk of abdominal aortic aneurysm?
Do inflammatory factors mediate the causal effect of lipid levels on the risk of abdominal aortic aneurysm?
This Mendelian randomization study provides genetic evidence that HDL protects against abdominal aortic aneurysm, an effect that is partially mediated by the anti-inflammatory cytokine IL-10.
• Mendelian randomization analysis revealed HDL protective (OR=0.600); LDL (OR=1.940) and TG (OR=1.536) increased AAA risk. • IL-10 uniquely showed a protective effect against AAA risk (OR=0.858); IL-1β, IL-6, IL-17, and TNF-α showed no causal links. • Two-step Mendelian randomization analysis identified IL-10 mediates 4.38% of HDL's protective effect against AAA development.
