Abstract

Introduction Previous studies have demonstrated an association between HIV infection and coronary artery disease (CAD); little is known about potential associations between HIV infection and extra-coronary calcification (ECC). Methods We analyzed 621 HIV infected (HIV+) and 384 HIV uninfected (HIV−) men from the Multicenter AIDS Cohort Study who underwent non-contrast computed tomography (CT) from 2010-2013. Agatston scores were calculated for mitral annular calcification (MAC), aortic valve calcification (AVC), aortic valve ring calcification (AVRC), and thoracic aortic calcification (TAC). The associations between HIV infection and the presence of each type of ECC (score > 0) were evaluated by multivariable logistic regression. We also evaluated the association of ECC with inflammatory biomarker levels and coronary plaque morphology. Results Among HIV+ and HIV− men, the age-standardized prevalences were 15% for TAC (HIV+ 14%/HIV− 16%), 10% for AVC (HIV+ 11%/HIV− 8%), 24% for AVRC (HIV+ 23% HIV− 24%), and 5% for MAC (HIV+ 7%/HIV− 3%). After adjustment, HIV+ men had 3-fold greater odds of MAC compared to HIV− men (OR = 3.2, 95% CI: 1.5–6.7), and almost twice the odds of AVC (1.8, 1.1–2.9). HIV serostatus was not associated with TAC or AVRC. AVRC was associated with higher Il-6 and sCD163 levels. TAC was associated with higher ICAM-1, TNF-α RII, and Il-6 levels. AVC and AVRC calcification were associated with presence of non-calcified plaque in HIV+ but not HIV− men. Conclusion HIV infection is an independent predictor of MAC and AVC. Whether these calcifications predict mortality in HIV+ patients deserves further investigation.
