Objectives
There is a growing need to understand the potential role of soluble platelet selectin (sP-selectin) in sustained endothelial activation through increased levels of soluble intercellular adhesion molecule-1 (sICAM-1) and soluble vascular adhesion-1 (sVCAM-1) in people living with HIV (PLWH) on highly active antiretroviral therapy (HAART).
Methodology
This was a cross-sectional study involving PLWH on HAART (n = 55), in comparison to PLWH not on treatment (HAART-naïve) (n = 29), and (iii) HIV negative controls (n = 48) from the Mankweng area in the Limpopo province, South Africa. We quantified serum levels of sP-selectin, together with sICAM-1 and sVCAM-1. Most of the HAART-exposed group were on treatment for <5 years. We further performed frequency distribution and descriptive statistics for categorical variables.
Results
Soluble P-selectin was positively correlated with sVCAM-1 (r = 0.469; p<0.001) in PLWH on HAART, even after adjusting for confounding factor such as age, BMI, and total cholesterol (r = 0.467; p<0.001). Moreover, in PLWH on HAART sP-selecting was independently associated with the release of sVCAM-1 (β = 0.445; p<0.001), even after adjusting for confounders (β = 0.475; p = 0.001). Serum levels of low-density lipoprotein cholesterol (LDL-C) (p = 0.004) and total cholesterol (p<0.001) were significantly higher in PLWH on HAART as compared to the HAART-naïve group.
Conclusion
There is a need for more studies to investigate the role of sP-selectin in promoting endothelial activation and CVD-risk in PLWH on HAART, especially within the sub-Saharan Africa region.
