BACKGROUND: HIV infection is associated with increased risk of cardiovascular disease beyond that explained by traditional risk factors. Altered gut microbiota, microbial translocation, and immune activation have been proposed as potential triggers. The microbiota-dependent metabolite trimethylamine-N-oxide (TMAO) predicts myocardial infarction (MI) in the general population and has recently been shown to induce platelet hyperreactivity. In the present study, we investigated if TMAO was associated with platelet function, microbial translocation, and immune activation in both untreated and combination anti-retroviral therapy (cART) HIV infection...

Cardiovascular disease, including atherosclerosis and atherosclerosis-associated complications, is an increasing cause of morbidity and mortality in human immunodeficiency virus (HIV) patients in the post-antiretroviral therapy era. HIV alone accelerates atherosclerosis. Antiretroviral therapy; HIV-associated comorbidities, such as dyslipidemia, drug abuse, and opportunistic infections; and lifestyle are risk factors for HIV-associated atherosclerosis. However, our current understanding of HIV-associated atherogenesis is very limited and has largely been obtained from clinical observation...

Little is known about the major cardiovascular risk factors in HIV-infected as compared to the HIV-uninfected patients in the Democratic Republic of Congo (DR Congo). We determined the prevalence of hypertension, obesity (BMI ≥ 30 kg/m(2)), total cholesterol > 200 mg/dl, HDL-cholesterol ≤ 40 mg/dl, and glycemia > 126 mg/dl. We also calculated the average and/or median of total cholesterol, HDL-cholesterol, and glycemia among HIV-infected and HIV-uninfected patients. We conducted a cross-sectional study that enrolled 592 HIV-uninfected and 445 HIV-infected patients of whom 425 (95...

OBJECTIVES: In Belgium, eleven AIDS Reference Centers (ARCs) and seven AIDS Reference Laboratories diagnose and treat HIV-positive individuals and track patients under care. As AIDS-related deaths are avoided and the HIV-positive population ages, non-infectious comorbidities (NICMs), such as cardiovascular disease, renal disease and certain cancers, play a larger role in the quality and length of patients' lives. This study aims to characterize the HIV-positive population in Belgium in terms of the prevalence of key NICMs...

Reduction in mortality and increased average life span of the human immunodeficiency virus (HIV)-infected patients treated with antiretroviral therapy (ART) are associated with the risk of unwanted effects, such as insulin resistance and dyslipidemia with cardiovascular complications. Antiretroviral therapy may also be associated with lipodystrophy characterized as peripheral lipoatrophy with central fat accumulation. Understanding the molecular mechanisms of lipodystrophy caused by ART is important for therapeutic strategy and the prediction of side-effects...

BACKGROUND: Wellens syndrome is a pattern of electrocardiographic (ECG) changes in the context of unstable angina characterized with deep inverted T-waves or biphasic T-waves in the precordial leads. These specific ECG changes are highly suggestive of stenosis in the left anterior descending artery (LAD), which can result in acute myocardial infarction, left ventricular dysfunction, or death. Human immunodeficiency virus (HIV) infection is known as an independent risk factor for the cardiovascular disease...

BACKGROUND: In order to investigate the mechanisms of cardiovascular disease in HIV infected and uninfected patients, an analysis of echocardiogram reports is required for a large longitudinal multi-center study. IMPLEMENTATION: A natural language processing system using a dictionary lookup, rules, and patterns was developed to extract heart function measurements that are typically recorded in echocardiogram reports as measurement-value pairs. Curated semantic bootstrapping was used to create a custom dictionary that extends existing terminologies based on terms that actually appear in the medical record...

Background: Cardiovascular disease (CVD) is an increasing cause of morbidity among persons living with HIV (PLWH). We projected cumulative CVD risk in PLWH in care compared to the US general population and persons HIV-uninfected, but at high risk for HIV. Methods: We used a mathematical model to project cumulative CVD incidence. We simulated a male and female cohort for each of three populations: 1) US general population; 2) HIV-uninfected, at high risk for HIV; and 3) PLWH...

Complications of HIV disease remained a major focus at the 2017 Conference on Retroviruses and Opportunistic Infections (CROI), and included studies focused on noncommunicable chronic diseases (eg, cardiovascular disease, obesity, bone disease, and malignancies) and opportunistic infections (Mycobacterium tuberculosis and cryptococcosis). Progress in identifying predictors of specific complications as well as interventions for the prevention and treatment of these comorbidities are summarized below.

BACKGROUND: Many factors are associated with HIV (the human immunodeficiency virus) patients having a greater risk of cardiovascular diseases. HIV damages vessel endothelium through chronic inflammation which combined with dyslipidemia, arterial hypertension and antiretroviral therapy leads to the progression of atherosclerotic changes. AIM: Our goal was to determine if a CD4 nadir along with immunologic, inflammatory, biochemical and metabolic markers can be associated with higher vessel stiffness and therefore an increased risk of cardiovascular diseases in patients undergoing antiretroviral therapy for HIV...
