Endothelial Dysfunction in Systemic Lupus Erythematosus and Systemic Sclerosis: A Common Trigger for Different...

Area of Science:

• Cardiovascular Medicine
• Rheumatology
• Vascular Biology

Background:

• Systemic autoimmune diseases, including systemic lupus erythematosus and systemic sclerosis, are associated with significant cardiovascular morbidity and mortality.
• Vascular dysfunction, characterized by inflammation, vasculopathy, and fibrosis, contributes to endothelial stiffness and damage in affected patients.
• Despite advances in diagnostics and therapies, cardiovascular mortality remains elevated in these patient populations.

Purpose of the Study:

• To review the complex interplay of inflammation, vasculopathy, and fibrosis in cardiovascular and peripheral small vessel disease in systemic autoimmune diseases.
• To highlight the increased cardiovascular mortality observed in patients with systemic lupus erythematosus and systemic sclerosis.
• To provide an overview of novel techniques for preclinical evaluation of endothelial dysfunction for cardiovascular risk assessment.

Main Methods:

• Literature review of studies on vascular dysfunction in systemic autoimmune diseases.
• Analysis of mechanisms linking inflammation, vasculopathy, and fibrosis to vascular damage.
• Overview of emerging diagnostic techniques for endothelial dysfunction.

Main Results:

• Systemic lupus erythematosus and systemic sclerosis serve as distinct models of vascular dysfunction in systemic autoimmune diseases.
• Endothelial stiffness, vascular damage, and premature aging are consequences of the described pathobiology.
• New techniques allow for preclinical evaluation of endothelial dysfunction, offering potential for improved cardiovascular risk assessment.

Conclusions:

• Vascular dysfunction is a critical determinant of excess cardiovascular mortality in systemic autoimmune diseases.
• Early detection of endothelial dysfunction using novel methods may improve cardiovascular risk stratification.
• Further research into these mechanisms and diagnostic tools is warranted to mitigate cardiovascular complications.
