OBJECTIVE: The role of HDL function in HIV-related atherosclerotic cardiovascular disease (CVD) is unclear. HDLs isolated from HIV+ [HIV(+)HDL] and HIV-uninfected individuals (HDL) were assessed for HDL function and ability to promote monocyte-derived foam cell formation (MDFCF) (a key event in HIV-related CVD) ex vivo. DESIGN/METHODS: Using an established in vitro model of atherogenesis and plasma samples from an established cross-sectional study of virologically-suppressed HIV+ males on stable effective antiretroviral therapy (ART) and with low CVD risk (median age: 42 years; n = 10), we explored the impact of native HDL [HIV(+)HDL] on MDFCF...

The number of older HIV-infected people is growing due to increasing life expectancies resulting from the use of antiretroviral therapy (ART). Both HIV and aging increase the risk of other comorbidities, such as cardiovascular disease, osteoporosis, and some malignancies, leading to greater challenges in managing HIV with other conditions. This results in complex medication regimens with the potential for significant drug-drug interactions and increased morbidity and mortality. Area covered: We review the metabolic pathways of ART and other medications used to treat medical co-morbidities, highlight potential areas of concern for drug-drug interactions, and where feasible, suggest alternative approaches for treating these conditions as suggested from national guidelines or articles published in the English language...

BACKGROUND AND PURPOSE: Cardiovascular disease associated with antiretroviral therapy (ART) has become a major clinical challenge for HIV-positive patients. However, the role of ART in blood vessel growth is largely unknown. Here, we examined an integral component of ART, nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs), and investigated their effects on key microvascular functions, including angiogenesis and lymphangiogenesis. EXPERIMENTAL APPROACH: The angiogenesis/lymphangiogenesis capability of endothelial cells (ECs) was evaluated using migration, proliferation and tube formation assays in vitro, and mouse ear and Matrigel plug assays in vivo...

PURPOSE OF REVIEW: Glucocorticoids have been the mainstay of treatment in systemic lupus erythematosus for more than half a century. Despite advancements in knowledge concerning the pathophysiology of systemic lupus, the genomic/non-genomic actions of glucocorticoids, and the use of novel therapeutic agents in SLE, the burden of toxicity from glucocorticoid use remains unchanged. RECENT FINDINGS: SLE patients receiving long-term prednisone therapy are at significant risk of morbidity due to permanent organ damage and prednisone daily dosages above 6 mg have been shown to increase the risk of future organ damage by 50%...

The survival of patients with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) who have access to highly active antiretroviral therapy (ART) has dramatically increased in recent times. This review focuses on HIV-associated heart failure in sub-Saharan Africa (SSA). In HIV infected persons, heart failure may be related to pathology of the pericardium, the myocardium, the valves, the conduction system, or the coronary and pulmonary vasculature. HIV-associated heart failure can be because of direct consequences of HIV infection, autoimmune reactions, pro-inflammatory cytokines, opportunistic infections (OIs) or neoplasms, use of ART or therapy for OIs and presence of traditional cardiovascular risk factors...

BACKGROUND: HIV-infected patients have an increased risk of cardiovascular disease (CVD). Impaired endothelial function is an early risk factor for CVD in the general population. It is presumed that HIV infection is associated with impaired endothelial function, but results have been inconsistent. OBJECTIVES: Our objectives were to determine the relationships between HIV infection, virologic suppression with antiretroviral therapy (ART), in vivo measures of conduit artery and microvascular endothelial function, and circulating biomarkers of pathways associated with CVD...

BACKGROUND: Little is known on the magnitude and correlates of insulin resistance in HIV-infected people in Africa. We determined the prevalence of insulin resistance and investigated associated factors in HIV-infected adult Cameroonians. METHODS: We conducted a cross-sectional study at the Yaoundé Central Hospital, Cameroon; during which we enrolled HIV-infected people aged 30 to 74 years with no previous history of cardiovascular disease. An homeostatic model assessment of insulin resistance (HOMA-IR) like index served to assess insulin sensitivity with insulin resistance defined by values of 2...

The prevalence of high blood pressure (HBP) and hypertension (HTN), awareness of the diagnoses, and use of anti-hypertensive drugs were examined among human immunodeficiency virus (HIV)-infected individuals on antiretroviral therapy (ART) in Zambia's capital Lusaka. Within a prospective cohort based at two public sector ART clinics, BP was measured at ART initiation and every 6 months thereafter as a routine clinic procedure. Predictors of HBP (systolic BP ≥140 mmHg or diastolic BP ≥90 mmHg) during one year on ART were analyzed using logistic regression, and the proportion with HTN (2+ episodes of HBP >3 months apart) described...

Lipid-lowering therapy effectively decreases cardiovascular risk on a population level, but it remains difficult to identify an individual patient's personal risk reduction while following guideline directed medical therapy, leading to overtreatment in some patients and cardiovascular events in others. Recent improvements in cardiac CT technology provide the ability to directly assess an individual's atherosclerotic disease burden, which has the potential to personalize risk assessment for lipid-lowering therapy...

Cancer was considered an incurable disease for many years; however, with the development of anticancer drugs and state-of-the art technologies, it has become curable. Cardiovascular diseases in patients with cancer or induced by cancer chemotherapy have recently become a great concern. Certain anticancer drugs and molecular targeted therapies cause cardiotoxicity, which limit the widespread implementation of cancer treatment and decrease the quality of life in cancer patients significantly. The anthracycline doxorubicin (DOX) causes cardiotoxicity...

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...

Myocardial infarction remains one of the top leading causes of death in the world and the damage sustained in the heart eventually develops into heart failure. Limited conventional treatment options due to the inability of the myocardium to regenerate after injury and shortage of organ donors require the development of alternative therapies to repair the damaged myocardium. Current efforts in repairing damage after myocardial infarction concentrates on using biologically derived molecules such as growth factors or stem cells, which carry risks of serious side effects including the formation of teratomas...
