Endothelial Dysfunction and Pentraxin-3 in Clinically Stable Adult Asthma Patients

Area of Science:

• Cardiovascular Medicine
• Pulmonology
• Immunology

Background:

• Asthma is associated with systemic inflammation, a prothrombotic state, and early atherosclerosis.
• Endothelial dysfunction is a key factor in cardiovascular disease development.

Purpose of the Study:

• To investigate the relationship between asthma, inflammatory biomarkers, and endothelial dysfunction parameters.
• To assess endothelial function using flow-mediated dilatation (FMD) and intima-media thickness (IMT).

Main Methods:

• Ultrasound assessment of brachial artery FMD and carotid artery IMT in 92 asthmatics and 62 controls.
• Measurement of inflammatory biomarkers including IL-4, IL-5, IL-6, IL-10, IL-12, IL-17A, IL-23, interferon γ, ADAM-33, vWF, and pentraxin-3.
• Correlation analysis with asthma severity, lung function, airway remodeling, and echocardiography parameters.

Main Results:

• Asthmatics exhibited higher levels of IL-6, IL-10, and ADAM-33 compared to controls.
• Asthmatics showed significantly reduced FMD (23%) and increased IMT (15%).
• Von Willebrand factor (vWF) correlated inversely with FEV1 and negatively with pentraxin-3.

Conclusions:

• Asthma is characterized by endothelial dysfunction, which is linked to airway obstruction.
• Pentraxin-3 may play a protective role against endothelial damage and atherosclerosis in asthma patients.
