Liver fibrosis is common, particularly in human immunodeficiency virus infected (HIV+) people. HIV+ people have excess congestive heart failure (CHF) risk compared to uninfected people. It remains unknown if stage of liver fibrosis influences the CHF risk or if HIV or hepatitis C virus (HCV) infection modifies this association. Our objectives were to assess whether: 1) stage of liver fibrosis is independently associated with incident CHF; 2) the association between stage of liver fibrosis and incident CHF is modified by HIV/HCV status...

HIV-associated lipodystrophy syndrome (HALS) is characterized by body fat redistribution as a consequence of the antiretroviral therapy (ART) introduction, associated with an increased risk of cardiovascular disease development. Subjective diagnosis, classified between three subtypes according to the body region on which fat is lost and/or accumulated, named lipoatrophy, lipohypertrophy, and mixed lipodystrophy, is possibly accompanied with metabolic alterations. Forty people living with HIV/AIDS (PLHA), with clinical diagnosis of HALS and from both genders, were assessed...

: There is a long-lasting controversy surrounding an association between Abacavir (ABC) and an increased risk of cardiovascular (CV) disease in HIV-positive subjects. While differing in their specifics, a number of published cohort studies and clinical trials support such an association, usually relating it to recent exposure to the drug, independently of traditional predisposing factors. However, other clinical trials have failed to reveal such a relation, and have pointed to methodological differences to explain discrepancies...

Hypertension is among the leading risk factors for cardiovascular disease and accounts for 6% of adult deaths worldwide. It is estimated that in 2013, hypertension was responsible for at least 45% of deaths due to heart disease and 51% of deaths due to stroke. Accordingly, management of hypertension and its long-term complications in HIV-infected subjects is a significant component of routine care. The choice of an effective anti-hypertensive therapy in HIV-infected patients is important and must be made carefully in order to prevent cardiovascular mortality and morbidity in these patients...

INTRODUCTION: HIV infection and certain antiretroviral therapy (ART) medications increase atherosclerotic cardiovascular disease risk, mediated, in part, through traditional cardiovascular disease risk factors. METHODS AND RESULTS: We studied cardiovascular disease risk factor changes in the START (Strategic Timing of Antiretroviral Treatment) trial, a randomized study of immediate versus deferred ART initiation among HIV-positive persons with CD4(+) cell counts >500 cells/mm(3)...

BACKGROUND: In Zambia, 14.2% of adults have HIV/AIDS. There has been a substantial and significant increase in patients hospitalized for ischaemic stroke with co-existing HIV infection. However, little is known about the mechanism of stroke in these HIV + ve patients let alone studied in our region. The aim of this pilot study was to explore the association of hypercoagulability state in HIV + ve patients with ischaemic stroke. This was achieved by comparing hypercoagulability state markers between HIV + ve ischaemic stroke patients with HIV-ve and HIV + ve patients with and without ischaemic stroke respectively...

BACKGROUND: Previous studies of cardiovascular disease (CVD) among HIV-infected individuals have been limited by the inability to validate and differentiate atherosclerotic type 1 myocardial infarctions (T1MIs) from other events. We sought to define the incidence of T1MIs and risk attributable to traditional and HIV-specific factors among participants in the North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD), and compare adjusted incidence rates to the general population Atherosclerosis Risk in Communities (ARIC) cohort...

An increase in the frequency of cardiovascular diseases has been observed in the HIV/AIDS population. Studies involving healthy subjects or subjects with other diseases have shown benefits of chocolate supplementation on endothelial function and vasodilation. We evaluate the impact of chocolate consumption on arterial elasticity in people living with human immunodeficiency virus - PLHIV. A double-blind, crossover trial including 110 PLHIV (19 to 59 years) on antiretroviral therapy - ART for at least 6 months and with a viral load of <500 copies per mL was conducted...

OBJECTIVES: With the increasing impact of cardiovascular disease among populations aging with HIV, contemporary prevalence estimates for predisposing metabolic comorbidities will be important for guiding the provision of relevant lifestyle and pharmacological interventions. We estimated the citywide prevalence of hypertension, type 2 diabetes, dyslipidaemia, and obesity; examined differences by demographic subgroups; and assessed clinical correlates. METHODS: Utilizing an electronic medical record (EMR) database from the DC Cohort study - a multicentre prospective cohort study of HIV-infected outpatients - we assessed the period prevalence of metabolic comorbidities between 2011 and 2015 using composite definitions that incorporated diagnoses, pharmacy records, and clinical/laboratory results...

The emergence of improved antiretroviral therapy has increased the life expectancy of human immunodeficiency virus (HIV)-infected individuals, though there is an increased susceptibility to developing cardiovascular diseases (CVD). The risk for CVD is purported to be even higher among people with HIV and hepatitis C virus (HCV) co-infection because of the increased inflammatory response, which may synergistically impact CV risk; however, studies comparing CV outcomes between HIV alone and HIV/HCV individuals have been discordant...

Cardiovascular disease remains a leading cause of morbidity and mortality in HIV positive patients, even in those whose viral loads are well controlled with antiretroviral therapy. However, the underlying molecular events responsible for the development of cardiac disease in the setting of HIV remain unknown. The HIV encoded Tat protein plays a critical role in the activation of HIV gene expression and profoundly impacts homeostasis in both HIV infected cells and uninfected cells that have taken up released Tat via a bystander effect...

BACKGROUND: Antiretroviral therapy (ART) improves the survival and quality of life of HIV-positive individuals, but the effects of long-term ART use do eventually manifest. The Complications of Long-Term Antiretroviral Therapy cohort study in Uganda (CoLTART) was established to investigate the metabolic and renal complications of long-term ART use among Ugandan adults. We describe the CoLTART study set-up, aims, objectives, study methods, and also report some preliminary cross-sectional study enrolment metabolic and renal complications data analysis results...

BACKGROUND: Immune activation persists despite suppressive antiretroviral therapy (ART) in human immunodeficiency virus (HIV) infection and predicts non-Acquired Immune Deficiency Syndrome (AIDS) comorbidities including cardiovascular disease. Activated platelets play a key role in atherothrombosis and inflammation, and platelets are hyperactivated in chronic HIV infection. Aspirin is a potent inhibitor of platelet activation through the cyclooxygenase-1 (COX-1) pathway. We hypothesized that platelet activation contributes to immune activation and that aspirin would reduce immune activation and improve endothelial function in ART-suppressed HIV-infected individuals...

Patients with human immunodeficiency virus (HIV) have increased risk of cardiovascular disease. Although evidence of subclinical atherosclerosis in perinatally acquired HIV (PHIV) is available, myocardial infarction has not been described in this population. We report a case of myocardial infarction in a patient with PHIV with a brief literature review.

Janessa M Smith, Charles Flexner
: It is estimated that by 2030 nearly three-quarters of persons living with HIV will be 50 years and older. The aging HIV population presents a new clinical concern for HIV providers: adverse effects from polypharmacy. An aging population means more comorbidities and potentially more drug-drug interactions for providers to manage. This review discusses major comorbidities including cardiovascular disease, anticoagulation, hypertension, diabetes mellitus and malignancy and considerations for drug-interactions with antiretrovirals...

: Populations living with HIV who access effective antiretroviral therapies are ageing and thus facing chronic disease-related comorbidities. Cardiovascular disease is now a leading cause of morbidity and mortality in the HIV population as in the general population. The increased incidence of cardiovascular complications experienced by the HIV population is due to physiological aging and consequently the increased risk of hypertension, diabetes, and renal failure. Whether HIV itself is an additive and independent risk factor for cardiovascular disease (CVD) remains a central question...

: Among HIV-infected persons, the assessment of nonalcoholic fatty liver disease (NAFLD) provides a window through which overall metabolic health can be evaluated. In this review, we summarize clinical data that support the roles of aging and metabolic dysregulation as factors contributing to fatty liver/NAFLD among HIV-infected persons.Age-related metabolic alterations include hepatic anatomic and functional changes, altered homeostasis of gastrointestinal microbiota and anthropometric changes (such as a shift of body fat depots from the subcutaneous to the visceral compartment) that are often associated with the development of insulin resistance and increased cardiovascular risk...
