ABSTRACT: Abstract
Antiretroviral therapy (ART) has improved survival of patients living with HIV (PLWH); however, this has been accompanied by an increase in cardiovascular disease (CVD). Although preventative measures for CVD among the general population are well described, information is limited about CVD prevention among PLWH. The goal of this study was to characterize the prevalence of CVD in our population and to assess the use of primary and secondary prevention.We performed a retrospective review of PLWH receiving primary care at a large academic center in Miami, Florida. We characterized the prevalence of CVD, CVD risk, and the use of aspirin and statins for primary and secondary CVD prevention.A total of 985 charts were reviewed (45% women, 55% men). Average age was 52.2 years. Average CD4 count was 568 cells/microL. 92.9% were receiving ART, and 71% were virologically suppressed. The median 10-year ASCVD risk was 7.3%. The prevalence of CVD was 10.4% (N = 102). The odds of having CVD was lower in patients on ART (OR 0.47, 95% CI: 0.25-0.90, P = .02). The use of medications for primary and secondary prevention of CVD based on current guidelines was low: 15% and 37% for aspirin respectively, and 25% and 44% for statins.CVD risk and rates of CVD are high among PLWH and receiving ART could protect against CVD. However, the use of medications for primary and secondary prevention is low. Increased awareness of CVD risk-reduction strategies is needed among providers of PLWH to decrease the burden of CVD.

Project description:Purpose of reviewTo highlight mechanisms of elevated risk of atherosclerotic cardiovascular disease (ASCVD) among people living with HIV (PLWH), discuss therapeutic strategies, and opportunities for primary prevention.Recent findingsHIV-associated ASCVD risk is likely multifactorial and due to HIV-specific factors and traditional risk factors even in the setting of treated and suppressed HIV disease. Although a growing body of evidence suggests that inflammation and immune activation are key drivers of atherogenesis, therapies designed to lower inflammation including colchicine and low-dose methotrexate have not improved secondary cardiovascular endpoints among PLWH. Statins continue to be the mainstay of management of hyperlipidemia in HIV, but the impact of newer lipid therapies including proprotein convertase subtilisin/kexin type 9 inhibitors on ASCVD risk among PLWH is under investigation. Aside from the factors mentioned above, healthcare disparities are particularly prominent among PLWH and thus likely contribute to increased ASCVD risk.SummaryOur understanding of mechanisms of elevated ASCVD risk in HIV continues to evolve, and the optimal treatment for CVD in HIV aside from targeting traditional risk factors remains unknown. Future studies including novel therapies to lower inflammation, control of risk factors, and implementation science are needed to ascertain optimal ways to treat and prevent ASCVD among PLWH.

Project description:BackgroundPeople living with HIV are diagnosed with age-related chronic health conditions, including cardiovascular disease, at higher than expected rates. Medical management of these chronic health conditions frequently occur in HIV specialty clinics by providers trained in general internal medicine, family medicine, or infectious disease. In recent years, changes in the healthcare financing for people living with HIV in the U.S. has been dynamic due to changes in the Affordable Care Act. There is little evidence examining how healthcare financing characteristics shape primary and secondary cardiovascular disease prevention among people living with HIV. Our objective was to examine the perspectives of people living with HIV and their healthcare providers on how healthcare financing influences cardiovascular disease prevention.MethodsAs part of the EXTRA-CVD study, we conducted in-depth, semi-structured interviews with 51 people living with HIV and 34 multidisciplinary healthcare providers and at three U.S. HIV clinics in Ohio and North Carolina from October 2018 to March 2019. Thematic analysis using Template Analysis techniques was used to examine healthcare financing barriers and enablers of cardiovascular disease prevention in people living with HIV.ResultsThree themes emerged across sites and disciplines (1): healthcare payers substantially shape preventative cardiovascular care in HIV clinics (2); physician compensation tied to relative value units disincentivizes cardiovascular disease prevention efforts by HIV providers; and (3) grant-based services enable tailored cardiovascular disease prevention, but sustainability is limited by sponsor priorities.ConclusionsWith HIV now a chronic disease, there is a growing need for HIV-specific cardiovascular disease prevention; however, healthcare financing complicates effective delivery of this preventative care. It is important to understand the effects of evolving payer models on patient and healthcare provider behavior. Additional systematic investigation of these models will help HIV specialty clinics implement cardiovascular disease prevention within a dynamic reimbursement landscape.Trial registrationClinical Trial Registration Number: NCT03643705 .

Project description:OBJECTIVES:There is a paucity of data on cardiovascular disease (CVD) among people living with HIV (PLHIV) in resource-limited countries. We assessed factors associated with CVD and the impact of prevalent CVD on all-cause mortality in PLHIV on antiretroviral therapy in Brazil. METHODS:Competing risk regression to assess factors associated with CVD and all-cause mortality in the HIV-Brazil Cohort Study between 2003 and 2014. RESULTS:Among 5614 patients, the rate of CVD was 3.5 (95% confidence interval [95% CI] 2.9-4.3) per 1000 person-years. CVD was associated with older age (adjusted hazard ratio [aHR] 6.4 for ≥55 years vs. <35 years, 95% CI: 2.5-16.3, P < 0.01), black race (aHR 1.8 vs. white race, 95% CI: 1.0-3.1, P = 0.04), past CVD (aHR 3.0 vs. no past CVD, 95% CI: 1.4-6.2, P < 0.01), hypertension (aHR 1.8 vs. no hypertension, 95% CI: 1.0-3.1, P = 0.04), high-grade dyslipidemia (aHR 9.3 vs. no high-grade dyslipidemia, 95% CI: 6.0-14.6, P < 0.01), ever smoking (aHR 2.4 vs. never, 95% CI: 1.2-5.0, P = 0.02) and low nadir CD4 cell count (aHR 1.8 for 100-250 cells/mm3 vs. >250 cells/mm3 , 95% CI: 1.0-3.2, P = 0.05). The rate of death was 16.6 (95% CI: 15.1-18.3) per 1000 person-years. Death was strongly associated with having had a past CVD event (aHR 1.7 vs. no past CVD event, 95% CI: 1.1-2.7, P = 0.01). CONCLUSIONS:Traditional and HIV-specific factors associated with CVD among PLHIV in Brazil are similar to those identified among PLHIV in high-income countries. PLHIV in Brazil with a history of CVD have a high risk of death. CVD care and treatment remain priorities for PLHIV in Brazil as this population ages and antiretroviral therapy use expands.

Project description:ObjectivesSocio-economic factors and lifestyle are known to differ across geographies and populations, which may result in distinct risk profiles for cardiovascular disease (CVD). This study assessed carotid intima-media thickness (CIMT), a proxy for CVD, and its determinants in two groups of people living with HIV (PLHIV) in two different settings in South Africa.MethodsA cross-sectional analysis was conducted comparing data from the Ndlovu Cohort Study in the Limpopo Province (group 1) and from three clinical trials in Johannesburg (group 2). The association between demographics, conventional CVD risk factors, HIV-related factors and CIMT in groups 1 and 2 was analysed with two separate multivariable linear regression models.ResultsGroup 1 consisted of 826 participants (mean age 42.2 years) and mean (± standard deviation) CIMT was 0.626 ± 0.128 mm. In this group, sex, age, body mass index (BMI), cholesterol, glucose and antiretroviral therapy (ART) duration (β = 0.011 mm per 5 years; P = 0.02) were associated with higher CIMT. There were positive interactions between age and ART duration and age and cholesterol. Group 2 consisted of 382 participants (mean age 39.5 years) and mean (± standard deviation) CIMT was 0.560 ± 0.092 mm. In this group, only sex, education level, BMI and cholesterol were associated with higher CIMT, albeit with weaker associations than in group 1.ConclusionsConventional CVD risk factors were the main drivers of CIMT. The impact of some of these risk factors appeared to increase with age. Differences in sample size, age and viral suppression might explain why an effect of ART was observed in group 1 but not in group 2.

Project description:IntroductionPeople living with HIV (PLHIV) have an elevated risk of atherosclerotic cardiovascular disease (CVD) compared to their HIV-negative peers. Expanding statin use may help alleviate this burden. However, the choice of statin in the context of antiretroviral therapy is challenging. Pravastatin and pitavastatin improve cholesterol levels in PLHIV without interacting substantially with antiretroviral therapy. They are also more expensive than most statins. We evaluated the cost-effectiveness of pravastatin and pitavastatin for the primary prevention of CVD among PLHIV in Thailand who are not currently using lipid-lowering therapy.MethodsWe developed a discrete-state microsimulation model that randomly selected (with replacement) individuals from the TREAT Asia HIV Observational Database cohort who were aged 40 to 75 years, receiving antiretroviral therapy in Thailand, and not using lipid-lowering therapy. The model simulated each individual's probability of experiencing CVD. We evaluated: (1) treating no one with statins; (2) treating everyone with pravastatin 20mg/day (drug cost 7568 Thai Baht ($US243)/year) and (3) treating everyone with pitavastatin 2 mg/day (drug cost 8182 Baht ($US263)/year). Direct medical costs and quality-adjusted life-years (QALYs) were assigned in annual cycles over a 20-year time horizon and discounted at 3% per year. We assumed the Thai healthcare sector perspective.ResultsPravastatin was estimated to be less effective and less cost-effective than pitavastatin and was therefore dominated (extended) by pitavastatin. Patients receiving pitavastatin accumulated 0.042 additional QALYs compared with those not using a statin, at an extra cost of 96,442 Baht ($US3095), giving an incremental cost-effectiveness ratio of 2,300,000 Baht ($US73,812)/QALY gained. These findings were sensitive to statin costs and statin efficacy, pill burden, and targeting of PLHIV based on CVD risk. At a willingness-to-pay threshold of 160,000 Baht ($US5135)/QALY gained, we estimated that pravastatin would become cost-effective at an annual cost of 415 Baht ($US13.30)/year and pitavastatin would become cost-effective at an annual cost of 600 Baht ($US19.30)/year.ConclusionsNeither pravastatin nor pitavastatin were projected to be cost-effective for the primary prevention of CVD among PLHIV in Thailand who are not currently using lipid-lowering therapy. We do not recommend expanding current use of these drugs among PLHIV in Thailand without substantial price reduction.

Project description:Hematopoietic stem cells (HSCs) with age-associated somatic mutations that disproportionally contribute to hematopoiesis generate the condition known as clonal hematopoiesis (CH). While CH conveys increased risk of hematologic cancer, there is also strong association between CH and cardiovascular disease (CVD). Accumulating evidence suggests that inflammation mechanistically links CH to CVD, and we hypothesized that CH may be a predictive biomarker of CVD in conditions of chronic inflammation. One such patient population comprises people living with HIV (PLWH) who also have substantially increased incidences of CVD and CH . We studied the association between CH and CVD in PLWH using samples from ACTG Study A5001 (or ALLRT), a prospective clinical trial of HIV-infected persons with long-term follow-up. We observed a positive association between CH and CVD in PLWH independent of traditional CVD risk factors. Moreover, in CVD cases, the CH clone was identifiable in the blood years before CVD diagnosis, unlike in PLWH with CH who did not have CVD. With the life span of PLWH increasing because of advances in treatment, our results indicate that the presence of CH and its clonal dynamics could be used as a prognostic biomarker of the risk for CVD in PLWH.

Project description:As early and effective antiretroviral therapy has become more widespread, HIV has transitioned from a progressive, fatal disease to a chronic, manageable disease marked by elevated risk of chronic comorbid diseases, including cardiovascular diseases (CVDs). Rates of myocardial infarction, heart failure, stroke, and other CVD manifestations, including pulmonary hypertension and sudden cardiac death, are significantly higher for people living with HIV than for uninfected control subjects, even in the setting of HIV viral suppression with effective antiretroviral therapy. These elevated risks generally persist after demographic and clinical risk factors are accounted for and may be partly attributed to chronic inflammation and immune dysregulation. Data on long-term CVD outcomes in HIV are limited by the relatively recent epidemiological transition of HIV to a chronic disease. Therefore, our understanding of CVD pathogenesis, prevention, and treatment in HIV relies on large observational studies, randomized controlled trials of HIV therapies that are underpowered to detect CVD end points, and small interventional studies examining surrogate CVD end points. The purpose of this document is to provide a thorough review of the existing evidence on HIV-associated CVD, in particular atherosclerotic CVD (including myocardial infarction and stroke) and heart failure, as well as pragmatic recommendations on how to approach CVD prevention and treatment in HIV in the absence of large-scale randomized controlled trial data. This statement is intended for clinicians caring for people with HIV, individuals living with HIV, and clinical and translational researchers interested in HIV-associated CVD.

Project description:BackgroundExpanding statin use may help to alleviate the excess burden of atherosclerotic cardiovascular disease in people living with HIV (PLHIV). Pravastatin and pitavastatin are preferred agents due to their lack of substantial interaction with antiretroviral therapy. We aimed to evaluate the cost-effectiveness of pravastatin and pitavastatin for the primary prevention of atherosclerotic cardiovascular disease among PLHIV in the United States.MethodsWe developed a microsimulation model that randomly selected (with replacement) individuals from the Data-collection on Adverse Effects of Anti-HIV Drugs study with follow-up between 2013 and 2016. Our study population was PLHIV aged 40 to 75 years, stable on antiretroviral therapy, and not currently using lipid-lowering therapy. Direct medical costs and quality-adjusted life-years (QALYs) were assigned in annual cycles and discounted at 3% per year. We assumed a willingness-to-pay threshold of $100,000/QALY gained. The interventions assessed were as follows: (1) treating no one with statins; (2) treating everyone with generic pravastatin 40 mg/day (drug cost $236/year) and (3) treating everyone with branded pitavastatin 4 mg/day (drug cost $2,828/year). The model simulated each individual's probability of experiencing atherosclerotic cardiovascular disease over 20 years.ResultsPersons receiving pravastatin accrued 0.024 additional QALYs compared with those not receiving a statin, at an incremental cost of $1338, giving an incremental cost-effectiveness ratio of $56,000/QALY gained. Individuals receiving pitavastatin accumulated 0.013 additional QALYs compared with those using pravastatin, at an additional cost of $18,251, giving an incremental cost-effectiveness ratio of $1,444,000/QALY gained. These findings were most sensitive to the pill burden associated with daily statin administration, statin costs, statin efficacy and baseline atherosclerotic cardiovascular disease risk. In probabilistic sensitivity analysis, no statin was optimal in 5.2% of simulations, pravastatin was optimal in 94.8% of simulations and pitavastatin was never optimal.ConclusionsPravastatin was projected to be cost-effective compared with no statin. With substantial price reduction, pitavastatin may be cost-effective compared with pravastatin. These findings bode well for the expanded use of statins among PLHIV in the United States. To gain greater confidence in our conclusions it is important to generate strong, HIV-specific estimates on the efficacy of statins and the quality-of-life burden associated with taking an additional daily pill.

Project description:Purpose of reviewWhile people with HIV (PWH) are living longer due to advances in antiretroviral therapy, recent data have demonstrated an increased risk of cardiovascular disease (CVD) among this population. This increased risk is thought to be due to both traditional (for example, smoking, diabetes) and HIV-specific (for example, inflammation, persistent immune activation) risk factors. This review focuses on the potential for statin therapy to mitigate this increased risk.Recent findingsSeveral randomized clinical trials have demonstrated that statins, a class of lipid-lowering medications, are effective as a primary CVD prevention strategy among people without HIV. Among PWH, statins have been shown to lower cholesterol, exert immunomodulatory effects, stabilize coronary atherosclerotic plaque, and even induce plaque regression.SummaryPrevention of CVD among the aging population of people with controlled, but chronic, HIV is vital. Data exploring primary prevention in this context are thus far limited. The Randomized Trial to Prevent Vascular Events in HIV (REPRIEVE) is ongoing; this trial will inform the field by investigating the effects of pitavastatin calcium as a primary prevention strategy for major adverse cardiovascular events among PWH on antiretroviral therapy (ART) at low-to-moderate traditional CVD risk.

Project description:Industrialized countries are currently experiencing an epidemic of high blood pressure (HBP) extending to people living with HIV (PLWH). Given the prevalence of hazardous alcohol use (HAU), this study examines the relationship between alcohol consumption and hypertension in PLWH. Including a gender analysis is critical, given the high rates of HAU and HIV among females.We followed PLWH including both HAU and non-HAU (200 each). Participants were assessed twice for body weight, blood pressure, alcohol consumption, and other BP-associated lifestyle factors. High blood pressure (defined as systolic/diastolic blood pressure above 140/90 mmHg and/or treatment of HBP) was the primary outcome.Overall prevalence of hypertension was 38% and higher among HAU compared to non-HAU (42% vs. 34%, p = 0.02). Less than half with HBP (42%) were receiving treatment for hypertension. Overall, males had a 50% higher risk of HBP than women (odds ratio: 1.5, 95% CI: 1-2.6, p = 0.05). However among HAU, females were twice as likely to suffer HBP as their male counterparts (95% CI: 1-3.9, p = 0.02). Those HAU who preferred liquor, versus wine, had higher adjusted mean BP (132.6±18 vs. 122.3±14 mm Hg, p = 0.05). Additional analyses indicated that consumption of >1 standard drink of liquor or beer/day was associated with HBP. Risk of hypertension was noted in those with daily consumption of >3 glasses of wine. For those reporting <1 drink per day, the odds ratio of having HBP was 0.97 (CI: 0.6-0.99, p = 0.05). Factors associated with hypertension in the multivariate model included increased age, gender, BMI, HAU particularly of liquor, and smoking.Excessive hypertension burden in this population and its association with HAU and sub-optimal care indicate the need for preventive and educational intervention in PLWH. Analyses highlight the necessity of gender and type-of-beverage specific approaches.
