Evaluations were performed on 27 HIV+ children and 30 HIV-healthy controls (2-21 years) who were prospectively enrolled in our pediatric cohort. Measurements included internal carotid artery (ICA) and common carotid artery (CCA) IMT, fasting lipids, insulin, proinflammatory markers (TNF-α, soluble TNF receptors (sTNFR-I, -II), IL-6, high sensitivity C-reactive protein (hsCRP), myeloperoxidase (MPO)), and adhesion molecules (soluble intercellular adhesion molecule-1, soluble vascular cell adhesion molecule-1 (sVCAM-1), von Willebrand factor).
Among HIV+, mean age was 11 years, 33 % males, 70 % black. 96 % acquired HIV vertically; median CD4 count (CD4 % ) was 1058 (35 % ) cells/ml; 96 % were on antiretroviral therapy (ART); 70 % had HIV-1 RNA <50 copies/ml. Groups were similar in age, race, sex, BMI, proinflammatory cytokines, adhesion markers, and carotid IMT except for hsCRP which was higher in HIV+ (P < 0.001). In multiple regression analyses, hCRP, age, and female sex were positively associated with IMT. ART duration and sTNFR-II were positively associated with sVCAM-1.
This study shows increased hsCRP in HIV+ children compared to healthy controls. As seen in adults, hCRP was associated with carotid IMT, which support a role for inflammation in CVD risk of HIV+ children.
