SEATTLE — Smoking rates appeared high among men who have sex with men with HIV and were associated with subclinical coronary atherosclerosis, according to data presented at CROI 2015.
Sean Kelly, MD, of the infectious disease department at Northwestern University Feinberg School of Medicine, and colleagues examined the coronary artery calcium (CAC) of 1,005 MSM enrolled in the Multicenter AIDS Cohort Study, including 612 infected with HIV. Participants semiannually self-reported recreational substance use up to 10 years prior, including tobacco, alcohol, stimulants, marijuana, inhaled nitrites and erectile dysfunction medication. CAC was measured in all patients through noncontrast computed tomography, with coronary CT angiograms (n = 764) also performed. Prevalence was determined through regression models stratified by HIV serostatus adjusted for age, race, education, CVD risk factors and HIV clinical factors.
Thirty-one percent of men with HIV were current smokers, compared with 22% of men without HIV. For patients with HIV, smoking was associated with CAC (OR = 2.3; 95% CI, 1.3-3.9), any plaque (OR = 2.3, 95% CI, 1.1-4.7), calcified plaque (OR = 2; 95% CI, 1.1-3.9) and coronary artery stenosis greater than 50% (OR = 2.6; 95% CI, 1.1-6), and former smoking with calcified plaque (OR = 2.2; 95% CI, 1.2-3.8) and stenosis (OR = 2.2; 95% CI, 1.1-4.7). Reporting more than 14 alcoholic drinks per week also was associated with stenosis (OR = 4.7; 95% CI, 1.5-14.8).
