cardiovascular-agents and HIV-Infections

HIV infection may affect the cardiovascular system through different physiopathological patterns. Rarely reported in HIV negative patients, aneurysms involving the carotid artery have been described for the first time in seropositive patients in 1989.. In our study, we have focused on aneurysm pathology affecting carotid arteries in HIV patients, analyzing clinical and surgical presentation, management, and outcome, through a review of cases published in the literature.. The MEDLINE (www.ncbi.nlm.nih.gov/pubmed) database was reviewed for "carotid artery aneurysm AND HIV OR AIDS OR immunodeficiency.". Nineteen articles including a total of 46 cases were included in our report. The mean age of patients was 30.6 ± 14.2 years; 30 patients (65.2%) were male. Aneurysms were localized in the intracranial carotid (41.3%) or extracranial artery (58%). Presenting features included symptoms due to compression of neck structures; positivity for neurological symptoms occurred in 36.9%. Patients were managed surgically in 58.7% of cases; surgical morbidity and mortality were of 22.2% and 7.4% respectively, higher for endovascular procedures. The overall mortality in treated and untreated cases was 26.1%.. Aneurysms may occur in both the extracranial and intracranial carotid artery in patients with HIV at younger age than in non-HIV patients and are linked to a high morbidity and mortality. Seropositivity must be ruled out whenever this rare vascular condition may occur in the absence of a more likely aetiology and must also be suspected in HIV patients presenting with compressive symptoms of the neck, neurological impairment or stroke.

The past 20 years have seen remarkable advances in the treatment of HIV such that most people diagnosed with HIV today can live long, healthy lives by taking antiretrovirals which are usually life-long. Advancements in antiretroviral therapy include the availability of well tolerated, single tablet regimens that are associated with a lower risk of drug-drug interactions. Despite this, many people living with HIV infection might be taking antiretroviral agents that are associated with significant drug-drug interactions. Because HIV infection itself is associated with cardiovascular complications and this population is living longer, concomitant use of antiretrovirals and medications to treat cardiovascular-related diseases is often required. For this reason, it is imperative that clinicians are aware of the potential for clinically significant drug-drug interactions between antiretroviral agents and cardiac medications as well as the useful HIV drug interaction resources that might provide guidance. Available data on significant interactions are summarized and suggested guidance regarding management is discussed.

HIV infection has progressed from an acute, terminal disease to a chronic illness with cardiovascular disease as the leading cause of death among persons living with HIV. As persons living with HIV infection continue to become older, traditional risk factors for atherosclerosis compounded by the pathophysiological effects of HIV infection and antiretroviral therapy markedly increase the risk for cardiovascular disease. Further, persons living with HIV are also at high risk for cardiomyopathy. Critical care nurses must recognize the risk factors for cardiovascular disease and the pathophysiology and complex treatment options in order to manage care of these patients and facilitate multidisciplinary collaboration. Two case studies are used to highlight the treatment options and nursing considerations associated with cardiovascular disease among persons living with HIV.

In 2012, the United Nations estimated that globally, 34 million people were living with human immunodeficiency virus (HIV) infection at the end of 2011. About 6.5% of AIDS-related mortality is attributable to cardiovascular disease. HIV related cardiovascular disease is diverse. In this review we explore the different disease states associated with HIV such as cardiomyopathy, coronary artery disease, dyslipidemia, electrocardiographic abnormalities, prolonged QT interval and sudden death. The pathophysiology of these numerous diseases is complex and multifactorial. Current management of these patients is challenging due to multiple drug-drug interactions and side effects. However, the approach to prevention is quite familiar, taking on the same rules that apply for any patient to minimize cardiovascular disease risk. The challenges are many, therefore for HIV patients who present after a cardiovascular event, or for prevention of cardiovascular disease, the concept of a heart team is essential, where cardiovascular specialists and the HIV care team work side by side to ensure safety of medications (avoid drug interactions) and to institute a goal directed prevention plan of care.

Cardiovascular disease (CVD) risk assessment tools such as the Framingham Risk Functions, often called Framingham Risk Scores, are common in the evaluation of the CVD risk among individuals in the general population. These functions are multivariate risk algorithms that combine data on CVD risk factors, such as sex, age, systolic blood pressure, total cholesterol level, high-density lipoprotein cholesterol level, smoking behavior, and diabetes status, to produce an estimate (or risk) of developing CVD or a component of it (such as coronary heart disease, stroke, peripheral vascular disease, and heart failure) over a fixed period (eg, the next 10 years). These estimates of CVD risk are often major inputs in recommending drug treatments, such as agents to reduce cholesterol level. The Framingham Risk Functions are valid in diverse populations, at times requiring a calibration adjustment for proper applicability. With the realization that individuals with human immunodeficiency virus (HIV) infection often have elevated CVD risk factors, the evaluation of CVD risk for these individuals becomes a serious concern. Researchers have recently developed new CVD risk functions specifically for HIV-infected patients and have also examined the extension of existing Framingham Risk Functions to the HIV-infected population. This article first reviews briefly the Framingham Study and risk functions, covering their objectives, their components, evaluation of their performance, and transportability and validity on non-Framingham populations. It then reviews the development of CVD risk functions for HIV-infected individuals and comments on the usefulness of extending the Framingham risk equation to the HIV-infected population and the need to develop more-specific risk prediction equations uniquely tailored to this population.

Knowledge of drug interactions is vital to maximize antiretroviral efficacy and avoid drug-related toxicities. Treatment of co-morbidities has become a difficult task in HIV-infected individuals because pharmacokinetic and/or pharmacodynamic interactions are common when other medications are prescribed along with antiretroviral agents.. This article provides an update of the most relevant drug interactions that occur between antiretroviral agents and other drugs. The article additionally revisits how these drug interactions can be prevented from occurring as well as how they can be managed.. Interactions between antiretrovirals and other drugs are frequent in clinical practice. The most common are those affecting drug metabolism due to induction or inhibition of the CYP450, leading to abnormal drug exposure. It is by this mechanism that most HIV protease inhibitors, non-nucleoside reverse transcriptase inhibitors and maraviroc often interact with other medications. In contrast, nucleoside reverse transcriptase inhibitors and some integrase inhibitors, which do not or only marginally affect CYP450, are relatively free of significant pharmacokinetic interactions, although nucleoside analogs might be involved in some pharmacodynamic interactions.

Darunavir is a new HIV protease inhibitor that has been shown to be highly useful in HIV-infected patients. This drug is primarily metabolized by the liver through the cytochrome P450 3A4 (CYP3A4) isozyme and consequently coadministration with low doses of ritonavir markedly increases exposure and allows both daily doses and pill burden to be reduced. Both darunavir and ritonavir act as inhibitors and substrates of CYP3A4 and may therefore present pharmacological interactions with a large number of drugs commonly used in HIV-infected patients. The present review aims to summarize the main studies that have evaluated drug interactions and to provide recommendations on treatment with darunavir/ritonavir in clinical practice.

New therapeutic options such as the highly active antiretroviral therapy (HAART) have significantly improved morbidity and mortality of HIV-infected patients. Consequently, age-related diseases become more manifest. In addition, HIV infection itself causes certain cardiovascular morbidity. Therefore, treatment of cardiovascular symptoms of HIV-positive patients becomes more and more important. Pharmacotherapy in these patients is complex and requires polypharmacy with drugs carrying a high risk of drug-drug interactions.

Abnormal levels of inflammation are associated with cardiovascular disease and mortality in human immunodeficiency virus (HIV)-infected patients. Microbial translocation, which may cause inflammation, is decreased by sevelamer in patients undergoing hemodialysis. In this single-arm study, we evaluated the effects of 8 weeks of sevelamer therapy on 36 HIV-infected subjects who were not receiving antiretroviral therapy. Sevelamer did not significantly change markers of microbial translocation, inflammation, or T-cell activation. During sevelamer treatment, however, levels of soluble tissue factor, low-density lipoprotein (LDL) cholesterol, and oxidized LDL cholesterol decreased significantly, whereas D-dimer levels increased. Thus, in this study population, sevelamer did not reduce microbial translocation but may have yielded cardiovascular benefits.. NCT 01543958.

To analyze the effect of a prevention program on the estimated cardiovascular risk calculated by three risk scores.. We prospectively evaluated 87 HIV+patients with elevated cardiovascular risk estimation. Framingham (FRS), PROCAM and National Cholesterol Education Program (ATP-III) were applied. Cardiovascular risk was defined as elevated if >10%. All patients received non-pharmacological (diet, exercise, smoking cessation) and, when appropriate, pharmacological therapy.. Mean age was 52 years, 92% were male, 39.1% were smokers, 70.1% had hypertension, 18.4% had diabetes. All patients were under HAART, 56.3% were receiving protease inhibitors (PI). After 6 months, intervention was associated to significant changes on triglycerides (298+/-242 and 206+/-135 mg/dL, p<0.05), total-cholesterol (224+/-47 and 189+/-38 mg/dL, p<0.001), LDL-cholesterol (129+/-44 and 109+/-30 mg/dL, p<0.001). Frequencies of patients with elevated cardiac risk before and 6 months after intervention were 92% x 27.6% (p<0.0001), 80.5% x 50.6% (p<0.0002), and 25.3% x 14.9% (p=0.12), for FRS, ATP III and PROCAM, respectively.. An intervention program focused on reduction of traditional risk factors was able to decrease the frequency of patients with HIV infection and elevated cardiovascular risk estimation. FRS showed greater sensitivity than the other scores.

We aimed to assess the validity of an announced telephone pill count in people with type 2 diabetes or cardiovascular disease by comparing this method to a home-visit pill count. We also assessed whether a second telephone pill count improved accuracy. People aged ≥35 years using oral type 2 diabetes or cardiovascular disease medication were included. Thirty-four participants completed a telephone pill count followed by a home-visit pill count, and a subsample of this population (n = 11) completed a second telephone pill count. Scatterplots were used for a visual representation of the number of pills counted with both methods, intraclass correlation coefficients for agreement, and Bland-Altman plots for absolute differences and outliers. A total of 203 pill counts were conducted. The study population consisted of 53% men, with a mean age of 69.6 (±9.2) years and an average of 6.1 (±2.8) medication prescriptions per participant. Scatterplots showed that pills counted with both methods were mostly scattered around the y = x equation. Agreement between the first telephone pill count and home-visit pill count was high, with intraclass correlation coefficients of 0.96 (medication count level) and 0.98 (individual level). No learning effects were observed in the subsample (n = 11), the intraclass correlation coefficient for the first telephone pill count was 0.88 versus 0.89 for the second telephone pill count. Bland-Altman plots indicated high agreement between the two methods. An announced telephone pill count is considered a valid alternative for a home-visit pill count in people with type 2 diabetes or cardiovascular disease. A single pill count appears sufficient.

: The risk of drug-drug interactions (DDIs) is elevated in aging people living with HIV (PLWH) because of highly prevalent age-related comorbidities leading to more comedications. To investigate the impact of aging on DDI magnitudes between comedications (amlodipine, atorvastatin, rosuvastatin) and boosted darunavir, we conducted a clinical trial in aging PLWH aged at least 55 years. DDI magnitudes were comparable with those reported in young individuals supporting that the clinical management of DDIs in aging PLWH can be similar.

The aim of this study was to assess the feasibility and preliminary outcomes of a medication self-management platform for chronically ill patients, Medplan.. We performed a 6-month single-arm prospective pre-post intervention study of patients receiving treatment for hypertension and/or dyslipidemia and/or heart failure and/or human immunodeficiency virus infection. During the pre-intervention phase, participants were followed according to their usual care; during the intervention phase, they used Medplan. We evaluated adherence, health outcomes, healthcare resources and measured the satisfaction of patients and health care professionals.. The study population comprised 42 patients. No differences were found in adherence to medication measured by proportion of days covered with medication (PDC). However, when adherence was measured using the SMAQ, the percentage of adherent patients improved during the intervention phase (p < 0.05), and the number of days with missed doses decreased (p < 0.05). Adherence measured using the Medplan app showed poor concordance with PDC. No differences were found in health outcomes or in the use of health care resources during the study period. The mean satisfaction score for Medplan was 7.2 ± 2.7 out of 10 among patients and 7.3 ± 1.7 among health care professionals. In fact, 71.4 % of participants said they would recommend the app to a friend, and 88.1 % wanted to continue using it.. The Medplan platform proved to be feasible and was well accepted by its users. However, its impact on adherence differed depending on the assessment method. The lack of effect on PDC is mainly because patients were already good adherers at baseline. The study enabled us to validate the platform in real patients using many different mobile devices and to identify potential barriers to scaling up the platform.

Persons living with HIV are at a higher risk of cardiovascular disease despite effective antiretroviral therapy and dramatic reductions in AIDS-related conditions. We sought to identify the epidemiology of heart failure (HF) among persons living with HIV in the United States in an era of contemporary antiretroviral therapy.. Explorys is an electronic healthcare database that aggregates medical records from 23 healthcare systems nationwide. Using systemized nomenclature of medicine-clinical terms (SNOMED-CT), we identified adult patients (age>18), who had active records over the past year (September 2014-September 2015). We described the prevalence of HF in HIV patients by demographics and treatment and compared them to HIV-uninfected controls.. Overall, there were 36,400 patients with HIV and 12,208,430 controls. The overall prevalence of HF was 7.2% in HIV and 4.4% in controls (RR 1.66 [1.60-1.72], p<0.0001). The relative risk of HF associated with HIV infection was higher among women and younger age groups. Patients receiving antiretroviral therapy had only marginally lower risk (6.4% vs. 7.7%, p<0.0001) of HF compared to those who were untreated. Compared to uninfected patients with HF, HIV patients with HF were less likely to receive antiplatelet drugs, statins, diuretics, and ACE/ARBs (p<0.0001 for all comparisons). For patients with HIV and HF, receiving care from a cardiologist was associated with higher use of antiplatelets, statins, betablockers, ACE/ARBs, and diuretics.. Persons with HIV are at higher risk for HF in this large contemporary sample that includes both men and women. Although the prevalence of heart failure is higher in older HIV patients, the relative risk associated with HIV is highest in young people and in women. HIV patients are less likely to have HF optimally treated, but cardiology referral was associated with higher treatment rates.

To compare the use of co-medication, the potential drug-drug interactions (PDDIs) and the effect on antiretroviral therapy (ART) tolerability and efficacy in HIV-infected individuals according to age, ≥ 50 years or <50 years.. All ART-treated participants were prospectively included once during a follow-up visit of the Swiss HIV Cohort Study. Information on any current medication was obtained by participant self-report and medical prescription history. The complete treatment was subsequently screened for PDDIs using a customized version of the Liverpool drug interaction database.. Drug prescriptions were analysed for 1497 HIV-infected individuals: 477 age ≥ 50 and 1020 age <50. Older patients were more likely to receive one or more co-medications compared with younger patients (82% versus 61%; P < 0.001) and thus had more frequent PDDIs (51% versus 35%; P < 0.001). Furthermore, older patients tended to use a higher number of co-medications and certain therapeutic drug classes more often, such as cardiovascular drugs (53% versus 19%; P < 0.001), gastrointestinal medications (10% versus 6%; P = 0.004) and hormonal agents (6% versus 3%; P = 0.04). PDDIs with ART occurred mainly with cardiovascular drugs (27%), CNS agents (22%) and methadone (6%) in older patients and with CNS agents (27%), methadone (15%) and cardiovascular drugs (11%) in younger patients. The response to ART did not differ between the two groups.. The risk for PDDIs with ART increased in older patients who take more drugs than their younger HIV-infected counterparts. However, medication use in older and younger patients did not differ in terms of effect on antiretroviral tolerability and response.

What is already known about this subject. Studies conducted primarily in developed countries have shown that adverse drug reactions (ADRs) are a significant cause of hospital admission, prolong hospital stay and consequently increase the cost of disease management in patients. Cardiovascular medicines, hypoglycaemic agents, nonsteroidal anti-inflammatory drugs and antibiotics are the most frequently implicated medicines in these studies. A large proportion of these ADRs have been shown to be preventable through improved drug prescribing, administration and monitoring for adverse effects. What this paper adds. This is the first Sub-Saharan African study in the HIV/AIDS era that describes the contribution of ADRs to patient morbidity, hospitalisation and mortality. Cardiovascular medicines and antiretroviral therapy contributed the most to community-acquired ADRs at the time of hospital admission while medicines used for opportunistic infections (such as antifungals, antibiotics and antituberculosis medicines were most frequently implicated in hospital acquired ADRs. ADRs in HIV-infected patients were less likely to be preventable.. To describe the frequency, nature and preventability of community-acquired and hospital-acquired adverse drug reactions (ADRs) in a South African hospital serving a community with a high prevalence of human immunodeficiency virus (HIV)/ acquired immunodeficiency syndrome.. A 3-month prospective observational study of 665 adults admitted to two medical wards.. Forty-one (6.3%) patients were admitted as a result of an ADR and 41 (6.3%) developed an ADR in hospital. Many of the ADRs (46.2%) were considered preventable, although less likely to be preventable in HIV-infected patients than in those with negative or unknown HIV status (community-acquired ADRs 2/24 vs. 35/42; P < 0.0001; hospital-acquired ADRs 3/25 vs. 14/26; P = 0.003). Patients admitted with ADRs were older than patients not admitted with an ADR (median 53 vs. 42 years, P = 0.003), but 60% of community-acquired ADRs at hospital admission were in patients <60 years old. Among patients <60 years old, those HIV infected were more likely to be admitted with an ADR [odds ratio (OR) 2.32, 95% confidence interval (CI) 1.17, 4.61; P = 0.017]. Among HIV-infected patients, those receiving antiretroviral therapy (ART) were more likely to be admitted with an ADR than those not receiving ART (OR 10.34, 95% CI 4.50, 23.77; P < 0.0001). No ART-related ADRs were fatal. Antibiotics and drugs used for opportunistic infections were implicated in two-thirds of hospital-acquired ADRs.. ADRs are an important, often preventable cause of hospitalizations and inpatient morbidity in South Africa, particularly among the elderly and HIV-infected. Although ART-related injury contributed to hospital admissions, many HIV-related admissions were among patients not receiving ART, and many ADRs were associated with medicines used for managing opportunistic infections.
