Exploring endothelial dysfunction in major rheumatic diseases: current trends and future directions.

Area of Science:

• Rheumatology
• Cardiovascular Medicine
• Immunology

Background:

• Rheumatic diseases (RDs) involve chronic inflammation and immune dysregulation.
• Endothelial dysfunction (ED) is characterized by reduced nitric oxide, oxidative stress, and inflammation.
• ED is a key factor in cardiovascular disease (CVD) development.

Purpose of the Study:

• To synthesize molecular mechanisms linking major RDs and ED.
• To identify potential biomarkers for ED in rheumatic patients.
• To inform strategies for mitigating cardiovascular risks in RD patients.

Main Methods:

• Literature review of studies on RDs, ED, and CVD.
• Analysis of molecular pathways connecting inflammation and endothelial function.
• Identification of shared pathways and potential therapeutic targets.

Main Results:

• Chronic inflammation in RDs directly impacts endothelial function, independent of traditional CVD risk factors.
• ED contributes significantly to atherosclerosis and elevated cardiovascular risk in RD patients.
• Specific molecular mechanisms linking RDs like rheumatoid arthritis, SLE, and psoriatic arthritis to ED were elucidated.

Conclusions:

• RDs promote ED via inflammatory and immune pathways, increasing CVD risk.
• Targeting ED mechanisms may offer novel therapeutic strategies for rheumatic diseases.
• Improved understanding of RD-ED interactions is crucial for managing cardiovascular outcomes in affected patients.
