Cardiometabolic Risk Profiles of Adolescents Living With Perinatally Acquired HIV in South Africa

Résumé fourni par la source

BACKGROUND: We assessed the Pathological Determinants of Atherosclerosis in Youth (PDAY) score and other potential cardiovascular disease risk factors in adolescents previously enrolled in the Children with HIV Early antiRetroviral (CHER) and International Maternal Pediatric Adolescent AIDS Clinical Trials Network P1060 clinical trials. METHODS: Coronary artery and abdominal aorta (AA) PDAY scores were calculated for 56 participants over 15 years of age using a weighted combination of dyslipidemia, cigarette smoking, hypertension, obesity, and hyperglycemia. A PDAY score ≥1 is associated with early atherosclerosis. RESULTS: Fifty-six participants were enrolled: 46 (82.1%) on a single-tablet regimen of tenofovir disoproxil fumarate, lamivudine and dolutegravir. Median time on antiretroviral therapy was 15.8 [interquartile range (IQR): 15.8-16.5] years and median time on dolutegravir was 14 (IQR: 10.0-19.0) months. Fasting median high-density lipoprotein cholesterol was 20.1 mg/dL (IQR: 16.0-23.7) and median non-high-density lipoprotein cholesterol was 38.3 mg/dL (IQR: 30.8-44.3). The median systolic blood pressure was 115 mm Hg (IQR: 107-121). Median body mass index was 21.3 kg/m 2 (IQR: 19.5-24.7) and median fasted serum glucose was 82.0 mg/dL (IQR: 75.7-87.3). Only 1 (2%) participant smoked cigarettes, but 5 (9%) smoked hookah pipe and 26 (46.4%) smoked cannabis. Thirty-one (55.4%) participants had coronary artery PDAY scores ≥1 and 33 (58.9%) had AA PDAY scores ≥1. Age was associated with an AA PDAY score ≥1 ( P = 0.02) with a 0.06 increase in AA PDAY score for every month of age (95% confidence interval: 0.01-0.12, P = 0.01). CONCLUSIONS: Adolescents with perinatally acquired HIV appear at risk for cardiovascular disease. Specific tools for monitoring this risk are needed to institute appropriate preventive interventions.
