The role of HIV as a risk modifier for coronary endothelial function in young adults.

Background: People living with HIV have an increased risk of cardiovascular disease (CVD). Although coronary endothelial function (CEF) is an early direct indicator of CVD, only a few studies have been able to interrogate CEF directly. Most studies have examined vascular endothelial function through indirect assessment of brachial flow-mediated dilatation (FMD).

Associations Between Central Obesity and Lifelong Antiviral Therapy in Adults Living With HIV Acquired From Early Childhood.

Background: Little is known regarding the long-term effects of antiretroviral (ARV) exposure on body composition for people living with HIV (PLWH) since early childhood. This study explores changes in body fat distribution in relation to ARV exposure.

Methods: We conducted a prospective study of adults with perinatal HIV (n = 70) using dual-energy X-ray absorptiometry and standard anthropometrics.

Brief Report: Adiponectin Levels Linked to Subclinical Myocardial Fibrosis in HIV.

Background: Persons living with HIV (PLWH) are at an increased risk of myocardial dysfunction and metabolic disturbances represent one of several potential contributing factors. Adiponectin is an adipokine that enhances insulin sensitivity with potential cardioprotective effects. We therefore investigated the relationship between myocardial fibrosis, adiponectin, and related metabolic parameters to better understand the pathophysiologic mechanisms of myocardial injury in PLWH.

Reproductive and sexual health knowledge, experiences, and milestones in young adults with life-long HIV.

Reproductive and sexual health outcomes of adults with perinatal human immunodeficiency virus (PHIV) have not been well-characterized. This prospective cross-sectional study of 35 adult persons living with HIV (PLWH) from early life and 20 matched HIV-negative controls assessed quality of life, depressive symptoms, HIV transmission knowledge, and sexual/reproductive behaviors through self-report questionnaires. PLWH scored significantly worse than controls on depressive symptoms ( = 0.

Unanticipated increases in hepatic steatosis among human immunodeficiency virus patients receiving mineralocorticoid receptor antagonist eplerenone for non-alcoholic fatty liver disease.

Background & Aims: Non-alcoholic fatty liver disease is common in human immunodeficiency virus, but there are no approved therapies. The aim of this open-label proof-of-concept study was to determine the effect of the mineralocorticoid receptor antagonist eplerenone on hepatic fat in human immunodeficiency virus-infected patients with hepatic fat ≥5% by magnetic resonance spectroscopy.

Methods: Five subjects received eplerenone (25 mg daily × 1 week followed by 50 mg daily × 23 weeks).

Effect of Antiretroviral Therapy on Bone and Renal Health in Young Adults Infected With HIV in Early Life.

Context: HIV antiretroviral (ARV) therapy is associated with renal and bone toxicity, but little is known about the potential cumulative effects in adults exposed to ARVs from birth.

Objective: To prospectively evaluate renal and bone health in young adults with lifelong HIV and extensive ARV exposure.

Design: Cross-sectional comparison of bone mineral density (BMD) by dual-energy X-ray absorptiometry, bone turnover, and renal function in young adults infected with HIV in early life (n = 65) to matched healthy controls (n = 23) and longitudinal evaluation (mean follow-up = 4.

T-cell Activation and E-selectin Are Associated With Coronary Plaque in HIV-infected Young Adults.

We evaluated immune activation and coronary artery plaque in young adults with human immunodeficiency virus acquired in early life (n = 31). Coronary plaque was positively associated with lipids, immune activation marker %CD8+CD38+DR+ and E-selectin, a marker of endothelial inflammation. Immune activation and endothelial inflammation may drive coronary plaque formation during the early stages of atherosclerosis in the context of chronic human immunodeficiency virus.

Lipolytic Rate Associated With Intramyocardial Lipid in an HIV Cohort Without Increased Lipolysis.

Context: Individuals with HIV have an elevated risk for developing cardiovascular disease compared to controls, particularly in relationship to abnormal deposition of lipid within various body compartments. Dysregulation of lipolysis may contribute to abnormal deposition of lipid in non-adipose tissues such as the heart, leading to untoward health consequences.

Objective: To evaluate potential relationships between rates of whole-body lipolysis and intramyocardial lipid content in HIV-infected subjects compared to healthy controls.

Abnormal Myocardial Function Is Related to Myocardial Steatosis and Diffuse Myocardial Fibrosis in HIV-Infected Adults.

Background: Impaired cardiac function persists in the era of effective human immunodeficiency virus (HIV) therapy, although the etiology is unclear. We used magnetic resonance imaging (MRI) to measure intramyocardial lipid levels and fibrosis as possible contributors to HIV-associated myocardial dysfunction.

Methods: A cross-sectional study of 95 HIV-infected and 30 matched-healthy adults, without known cardiovascular disease (CVD) was completed.

Increased coronary vessel wall thickness in HIV-infected young adults.

Background: Individuals with long-term human immunodeficiency virus (HIV) infection are at risk for premature vasculopathy and cardiovascular disease (CVD). We evaluated coronary vessel wall thickening, coronary plaque, and epicardial fat in patients infected with HIV early in life compared with healthy controls.

Methods: This is a prospective cross-sectional study of 35 young adults who acquired HIV in early life and 11 healthy controls, free of CVD.

Microalbuminuria in HIV disease.

Background/aims: Microalbuminuria is a marker for early kidney disease and cardiovascular risk. The purposes of this study were to determine the prevalence of microalbuminuria in an HIV-infected clinic population, to test the predictive value of a single urine albumin/creatinine ratio (ACR) to identify persistent microalbuminuria and to examine covariates of microalbuminuria.

Methods: We conducted a prospective cohort study of HIV-infected subjects (n = 182) without proteinuria (urine protein/creatinine ratio ≥0.

High rate of coronary artery abnormalities in adolescents and young adults infected with human immunodeficiency virus early in life.

We completed a cross-sectional study of individuals infected with human immunodeficiency virus in early childhood using cardiac magnetic resonance imaging and magnetic resonance angiography. Coronary artery abnormality (CAA) was defined by the presence of luminal narrowing and irregularity of the coronary vessel wall. More than 50% of participants (14/27) had evidence of CAA.

Longitudinal assessment of metabolic abnormalities in adolescents and young adults with HIV-infection acquired perinatally or in early childhood.

Metabolic complications of HIV pose challenges for health maintenance among young adults who acquired HIV in early childhood. Between July 2004 and July 2009, we evaluated 47 HIV-infected subjects who acquired HIV in early life. Participants completed glucose tolerance testing; insulin, lipid, urine albumin, and creatinine determinations; and dual-energy x-ray absorptiometry scans.

Decreased bone mineral density with off-label use of tenofovir in children and adolescents infected with human immunodeficiency virus.

5 of 6 children infected with human immunodeficiency virus (HIV) receiving Tenofovir disoproxil fumarate (TDF) experienced absolute decreases in bone mineral density (BMD). 2 pre-pubertal subjects experienced >6% BMD decreases. 1 subject was the smallest child and experienced a 27% decrease, necessitating withdrawal of TDF.

Virologic response using directly observed therapy in adolescents with HIV: an adherence tool.

Virologic response to highly active antiretroviral therapy (HAART) treatment of HIV infection depends on viral sensitivity to antiretrovirals and excellent medication adherence. Adolescents with vertically acquired HIV may require complicated regimens because of significant treatment experience and often have poor medication adherence. A retrospective chart review identified five adolescents with vertically acquired HIV and plasma HIV viral load rebound or nonresponse on a stable HAART regimen followed by a period of directly observed therapy (DOT) in a clinic or hospital setting with serial viral load measurements.
