Although HIV and antiretroviral therapy (ART) have been linked with an increased cardiovascular risk, the pathological pathways remain unknown. We assessed whether secretory phospholipase A2 (sPLA2), high-sensitivity C-reactive protein (hs-CRP), vascular cell adhesion molecule (VCAM), thiobarbituric acid reactive species (TBARS), Superoxide dismutases (SOD), adiponectin and resistin were elevated in HIV infected patients with detectable and undetectable viral load compared to a control group matched for age, sex and cardiovascular risk factors. We evaluated its correlation with traditional and no traditional cardiovascular risk factors and carotid intima-media thickness. Levels of sPLA2 (median [IQR]) were 8.35 (5.36, 9.6) pg/ml, hsCRP were 3.3 (IQR, 1.27, 5.28) mg/L, VCAM 945.6 (IQR, 655.9, 1404.05) ng/ml and TBARS 1.69 (IQR, 1.39, 1.97) uM/L in HIV infected group compared to levels of sPLA2 1.22 (IQR, 0.69, 2.62) pg/ml (p<0.001), hsCRP 3.05 (IQR, 2.68, 3.27) mg/L (p=0.05), VCAM 678.35 (IQR, 530.39, 831.04) ng/ml (p<0.001) and TBARS 7.47 (IQR, 5.03, 10.4) uM/L (p<0.001) in control group. Levels of VCAM (median [IQR]) were 1047.19 (IQR, 609.06, 1084.1) ng/ml (p=0.015) and sPLA2 were 7.6 (IQR, 5.25, 9.6) pg/ml (p<0.001) in HIV infected patients with undetectable viral load compared to control group. There was a good correlation between all analyzed biomarkers and cardiovascular risk factors. In conclusion, HIV infection induces chronic inflammation and endothelial activation that is not completely suppressed by the treatment.
