Abstract:
Objectives To investigate the markers of endothelial injury, adipocytokine and thrombotic activity and explore whether there are cardiovascular disease risk factors in antiretroviral-naive HIV patients. Methods Clinical data and venous blood samples were collected from 43 anti-retroviral naive HIV-infected patients during February -October 2009 in our center, and compared with 17 healthy subjects.Plasma leptin, adiponectin, soluble intercellular adhesion molecule-1 ( sICAM-1 ), D-dimer were measured by ELISA. Four markers and cholesterol, triglyceride, fasting plasma glucose were compared between the two groups. The CD4+ T cells and percentages of CD38, HLA-DR on CD8+ T were determined by flow cytometry and plasma HIV copies were detected with bDNA analyzer among HIV-infected participants.Spearman correlations between the significant markers and CD4+ T cells, CD8+ CD38+/CD8+, CD8+ HLA-DR +/CD8+, HIV viral load were examined among HIV-infected participants. Analyses were conducted by using Stata version 7. Results Thirty-eight of the 43 patients were sexually infected by HIV and the median absolute CD4+ T cell count was ( 133 ± 82 ) cells/μl, HIV RNA was (4. 42 ± 0. 66 ) lg copies/ml. HIV-infected patients, compared with healthy subjects, had lower leptin [11.41 (7.91,14. 53 )μg/L vs 55.31( 16. 49,229.65 ) μg/L, P= 0. 0005], adiponectin [1.79 ( 1.40,4. 00 ) mg/L vs 3.36 ( 2. 92,4. 18 ) mg/L,P =0. 003] and higher sICAM-1 [1.71 (1.11,2.40) mg/L vs 0. 69 ( 0. 57, 0. 80 ) mg/L, P = 0. 0000].No significant differences exist in cholesterol, triglyceride, fasting plasma glucose. For HIV-infected participants, sICAM-1 tended to correlate with CD8+ CD38+/CD8+ and HIV viral load ( r= 0.3378, P= 0.0267;r = 0.3904,P = 0.0096). Conclusion Patients with untreated HIV infection have lower leptin, adiponectin and higher sICAM-1 levels and the relationship of these markers to HIV-mediated atherosclerotic risk requires further study.
