Endothelial adhesion molecules are associated with inflammation in subjects with HIV disease

Area of Science:

• Cardiovascular Disease Research
• Immunology
• HIV/AIDS Research

Background:

• Intercellular adhesion molecule-1 (ICAM-1) and soluble vascular cell adhesion molecule-1 (VCAM-1) are linked to cardiovascular disease risk.
• Individuals with human immunodeficiency virus (HIV) often exhibit multiple cardiovascular disease risk factors.
• Elevated ICAM-1 and VCAM-1 levels are observed in patients with HIV disease.

Purpose of the Study:

• To assess variables associated with elevated adhesion molecule levels in patients with HIV disease.
• To investigate the relationship between adhesion molecules and cardiovascular risk factors in HIV patients.

Main Methods:

• Serum levels of ICAM-1 and VCAM-1 were measured in HIV-positive and HIV-negative subjects.
• Pearson correlation and multiple regression modeling were employed to analyze associations.
• Variables assessed included CD4+ cell count, HIV viral load, insulin sensitivity, and lipid levels.

Main Results:

• HIV-positive subjects demonstrated higher levels of ICAM-1 and VCAM-1.
• Significant correlations were found between adhesion molecules, insulin sensitivity, lipid levels, and soluble tumor necrosis factor-alpha receptor 2 (sTNFR2).
• sTNFR2 emerged as the sole independent predictor of ICAM-1 and VCAM-1 levels after controlling for other variables.

Conclusions:

• Inflammation, indicated by sTNFR2, appears to be a key factor influencing ICAM-1 and VCAM-1 levels in HIV disease.
• These findings highlight the role of inflammation in cardiovascular risk associated with HIV.
• Further research into anti-inflammatory strategies may be beneficial for managing cardiovascular risk in this population.
