History of AIDS in HIV-Infected Patients Is Associated With Higher In-Hospital Mortality Following Admission for Acute Myocardial Infarction and Stroke

Symptomatic HIV infection and in-hospital outcomes for patients with acute myocardial infarction undergoing percutaneous coronary intervention from national inpatient sample

Human immunodeficiency virus (HIV) infection increases the risk of acute myocardial infarction (AMI). However, little is known about its association with in-hospital outcomes and temporal trends in patients with AMI undergoing percutaneous coronary intervention (PCI). We queried patients with AMI who underwent PCI from the National Inpatient Sample Database (2003-2015) and stratified them into three groups: symptomatic, asymptomatic, and HIV-negative. After 1:2 case-control matching (CCM), logistic regression analysis was conducted to determine how HIV infection affected in-hospital outcomes. We also evaluated their recent trends from 2003 to 2015. The total weighted national estimate of 2,191,129 AMI cases included 2,178,995 HIV/AIDS-negative, 4994 asymptomatic, and 7140 symptomatic HIV cases. Symptomatic but not asymptomatic patients with HIV suffered more than triple the in-hospital mortality (adjusted odds ratio (aOR) 3.6, 95% confidence interval (CI) 2.5-5.2), over one-fold incidence of acute kidney injury (aOR 2.6 95% CI 1.9-3.4) and cardiogenic shock risk (aOR 1.9, 95% CI 1.3-2.7), a longer length of hospital stay (beta 1.2, 95% CI 1.0-1.5), and had more procedures (beta 1.3, 95% CI 1.2-1.5). These disparities relating to symptomatic HIV infection persisted from 2003 to 2015. In patients with AMI who underwent PCI, symptomatic HIV infection was associated with higher in-hospital mortality and more severe outcomes.

Prevalence of severe cardiovascular abnormalities amongst West African HIV-infected patients on antiretroviral therapy followed at a referral HIV centre

Background

With success and effective long-term antiretroviral treatment (ART), HIV-infected patients live longer and frequently developed non-communicable diseases (NCDs). Few studies have been conducted in low-income countries, particularly in West Africa.

Methods

We carried out a cross-sectional study in the referral HIV centre of the Service des Maladies Infectieuses et Tropicales (SMIT) in Abidjan. From April to September 2015, we consecutively included HIV-1 infected patients aged 18 years and older, and on ART for a minimum of 12 months. Data were collected using a structured questionnaire, and entered into the centre’s computerised HIV database. Clinical assessment, laboratory tests, electrocardiogram, transthoracic echocardiography and vascular Doppler ultrasound were performed. The main outcome was the prevalence of patients with severe cardiovascular abnormalities (SCA). Univariate and multivariate logistic regressions were used to identify factors associated with SCA.

Results

Out of 278 patients (median age 46 years, interquartile range [IQR: 41–52]), 74.5% were female. Overall, the median duration of ART was 84 months (IQR: 54–126). One hundred and ninety-nine (71.6%) patients were on first-line ART regimen and 229 (82.4%) were virologically suppressed with a median CD4 count of 511 cells/mm³ (IQR: 347–529). Basically, cardiovascular abnormalities were mainly non-obstructive carotid plaques (19.1%) followed with left ventricular diastolic dysfunction (16.5%). The overall prevalence of SCA in the study population was 7.6% (95% Confidence Interval [95% CI]: 4.7–11.3). The prevalence of SCA 7.6% (95% Confidence Interval [95% CI]: 4.7–11.3). In multivariate analysis, age > 50 years and nadir CD4 count > 200 cells/mm³ were significant predictors of SCA.

Conclusion

The prevalence of SCA is high in West African HIV-treated patients. Given the high mortality associated with cardiovascular diseases in the general population, refining disease preventive strategies in HIV-positive subjects is essential to continue prolonging their life.

Pericardial Adipose Tissue Volume Is Independently Associated With Human Immunodeficiency Virus Status and Prior Use of Stavudine, Didanosine, or Indinavir

BACKGROUND

Increased pericardial adipose tissue is associated with higher risk of cardiovascular disease. We aimed to determine whether human immunodeficiency virus (HIV) status was independently associated with larger pericardial adipose tissue volume and to explore possible HIV-specific risk factors.

METHODS

Persons with HIV (PWH) were recruited from the Copenhagen Comorbidity in HIV Infection (COCOMO) Study and matched 1:1 on age and sex to uninfected controls. Pericardial adipose tissue volume was measured using cardiac computed tomography.

RESULTS

A total of 587 PWH and 587 controls were included. Median age was 52 years, and 88% were male. Human immunodeficiency virus status was independently associated with 17 mL (95% confidence interval [CI], 10-23; P < .001) larger pericardial adipose tissue volume. Larger pericardial adipose tissue volume was associated with low CD4+ nadir and prior use of stavudine, didanosine, and indinavir. Among PWH without thymidine analogue or didanosine exposure, time since initiating combination antiretroviral treatment (per 5-year use) was associated with l6 mL (95% CI, -6 to -25; P = .002) lower pericardial adipose tissue volume.

CONCLUSIONS

Human immunodeficiency virus status was independently associated with larger pericardial adipose tissue volume. Severe immunodeficiency, stavudine, didanosine, and indinavir were associated with larger pericardial adipose tissue volume. Persons with HIV with prior exposure to these drugs may constitute a distinct cardiovascular risk population.

Impact of Advanced HIV Disease on Quality of Life and Mortality in the Era of Combined Antiretroviral Treatment

Currently, AIDS or severe immunodeficiency remains as a challenge for people with HIV (PWHIV) and healthcare providers. Our purpose was to analyze the impact of advanced HIV disease (AHD) on mortality, life expectancy and health-related quality of life (HRQoL). We reviewed cohort studies and meta-analyses conducted in middle- and high-income countries. To analyze HRQoL, we selected studies that reported overall health and/or physical/mental health scores on a validated HRQoL instrument. AIDS diagnosis supposes a higher risk of mortality during the first six months, remaining higher for 48 months. It has been reported that cancer and cardiovascular disease persist as frequent causes of mortality in PWHIV, especially those with previous or current AHD. PWHIV who initiate combination antiretroviral therapy (cART) with CD4 < 200 cells/µL have significantly lower estimated life expectancy than those with higher counts. AHD is associated with lower HRQoL, and a worse physical health or mental health status. AIDS and non-AIDS defining events are significant predictors of a lower HRQoL, especially physical health status. AHD survivors are in risk of mortality and serious comorbidities, needing special clinical attention and preventive programs for associated comorbidities. Their specific needs should be reflected in HIV guidelines.

A 10-Years Risk of Cardiovascular Disease Among HIV-Positive Individuals Using BMI-Based Framingham Risk Score in Indonesia

Introduction

Cardiovascular disease (CVD) is the primary cause of death in HIV patients. The number of HIV patients suffering from cardiovascular disease is almost twice as high as that of patients who are not HIV-positive.

Objective

The purpose of this study was to evaluate risk of cardiovascular disease among HIV-positive persons.

Methods

We conducted a cross-sectional study with HIV positive individuals at public health center and non-AIDS govermental organization. We enrolled people diagnosed with HIV, age over 30 years old, and on CVD medications. We collected data of demographic, anthropometric and clinical information, smoking history, and non-fasting cholesterol and blood glucose. Estimation of 10-years CVD risk was calculated using the BMI-based Framingham Risk Score.

Results

Of 150 participants enrolled, 66.7% were male and mean age was 38.09 (SD = 7.99) years. The mean current CD4 counts was 493.3 (SD = 139.8) cells/mm3. Female were younger, had a shorter duration living with HIV and a shorted duration of receiving ART than males. About 8.7% of respondents had a high risk of developing a CVD event in the next 10 years, and higher among females than males. The most common CVD risk factors were smoking, high blood pressure, and hypercholestrolemia.

Conclusion

Our study demonstrates that HIV positive persons who are at risk for developing CVD in the next 10-years. There is an increasing need for educational programs on CVD prevention for the HIV-positive person and to further facilitate the identification of persons at elevated risk in routine practice.

CD4/CD8 Ratio and CD4 Nadir Predict Mortality Following Noncommunicable Disease Diagnosis in Adults Living with HIV

Incidence of noncommunicable diseases (NCDs), including cardiovascular disease (CVD), cirrhosis, and non-AIDS-defining cancers (NADCs), have been associated with HIV viremia, CD4 cell counts, and CD4/CD8 ratio in persons living with HIV (PLWH). This study examined the importance of these markers to mortality risk following NCD diagnosis. We examined factors associated with mortality following incident CVD, cirrhosis, or NADCs in a clinical cohort of PLWH between 1998 and 2015. We calculated Kaplan-Meier estimates and used multivariable Cox proportional hazard models. We included 341 patients with NCDs (CVD = 169, cancer = 103, and cirrhosis = 67), of whom 129 died. Median age at NCD diagnosis was 49 years and median proportion of time before NCD with virologic suppression was 64%. Median survival after CVD was longer than for cancer or cirrhosis (11.6 years vs. 4.8 and 3.4 years, respectively; log rank test p < .001). In multivariable Cox proportional hazard models, higher CD4/CD8 ratio preceding NCD (adjusted hazard ratio [aHR] per 0.1 increase = 0.92 [95% confidence interval 0.85-0.99]) and higher CD4 nadir (aHR per 100 cells/μL = 0.84 [0.72-0.97]) were associated with decreased mortality risk. Neither CD4 cell count before NCD nor HIV viremia was statistically associated with mortality in adjusted models. When restricted to 116 patients with virologic suppression for ≥80% of time before NCD, only CD4 nadir was associated with mortality risk. Low CD4/CD8 ratio and CD4 nadir were associated with increased mortality risk after NCD, suggesting that prior immunosuppression or ongoing immune imbalance remain important for outcomes following serious NCDs.

HIV and Cardiovascular Disease: Update on Clinical Events, Special Populations, and Novel Biomarkers

PURPOSE OF REVIEW

The objective of this review is to provide an update on the link between HIV infection and cardiovascular disease (CVD). We will focus our review mainly on literature describing clinical CVD events and understudied topics of importance.

RECENT FINDINGS

Heart failure, peripheral artery disease, and stroke are CVD modalities deserving more attention in the context of HIV infection in the highly active antiretroviral therapy era. Incidence data on clinical CVD from HIV populations in low- and middle-income countries are limited. Multisubstance use is common in HIV, but understudied as a moderator or mediator of the association between HIV and CVD. CVD risk assessment in HIV remains challenging, but new research into novel biomarkers may provide further insights. There is also a need for inclusion of non-biologic factors in our attempts to understand, quantify, and predict CVD risk among PLWHA. Significant attention has been paid to generating and testing hypotheses to understand the mechanisms of myocardial infarction in HIV. Similar attention is deserving for heart failure, PAD, stroke, and cardiovascular disease risk in resource-limited settings and among substance users with HIV.

HIV-related excess mortality and age-related comorbidities in patients with HIV aged ≥60: a relative survival analysis in the French Dat'AIDS cohort

OBJECTIVE

The objective was to evaluate the association between age-related comorbidities (ARCs) and 5-year HIV-related excess mortality in people living with HIV aged ≥60 years.

DESIGN

Cohort study using relative survival analysis (Estève's model).

SETTING

The French multicentre prospective Dat'AIDS cohort that involves 12 French hospitals.

PARTICIPANTS

Inclusion of 1415 HIV-1 infected patients actively followed aged ≥60 years on January 2008, with a 5-year follow-up period in the late combination antiretroviral therapy era.

RESULTS

Among 1415 patients included, 154 died. By multivariable analysis, factors predictive of 5-year HIV-related excess mortality were non-AIDS-related cancer (adjusted excess HR (aEHR)=2.94; 95% CI 1.32 to 6.57), cardiovascular disease (aEHR=6.00; 95% CI 2.45 to 14.65), chronic renal disease (aEHR=4.86; 95% CI 2.24 to 10.53), cirrhosis (aEHR=3.58; 95% CI 1.25 to 10.28), hepatitis C co-infection (aEHR=3.63; 95% CI 1.44 to 9.12), body mass index<18.5 kg/m² (aEHR=4.10; 95% CI 1.61 to 10.48) and having a CD4 cell count ≤200/mm³ (aEHR=5.79; 95% CI 2.28 to 14.69).

CONCLUSIONS

ARCs, particularly cardiovascular disease and chronic renal disease, are predictive of HIV-related excess mortality, with an increase in hazard similar to that of CD4 cell count.

Stroke in HIV

Stroke is a heterogeneous disease in persons living with human immunodeficiency virus (HIV). HIV is thought to increase the risk of stroke through both HIV-related and traditional stroke risk factors, which vary with respect to the patient's age and clinical characteristics. Numerous studies show that detectable viremia and immunosuppression increase the risk of stroke across all ages, whereas traditional risk factors are more common in the aging population with HIV. As persons living with HIV age and acquire traditional stroke risk factors, the prevalence of stroke will likely continue to increase. Large- and small-vessel disease are the most common causes of stroke, although it is important to evaluate for infectious etiology as well. Research regarding the management of stroke in patients with HIV is scant, and recommendations often parallel those for the general population. Treatment of HIV and effective reduction of traditional stroke risk factors is important to reduce the risk of stroke in persons living with HIV. Future research will help elucidate the pathophysiology of HIV and stroke risk, investigate sex differences in stroke risk, and evaluate the safety and benefits of standard stroke preventative measures and HIV-specific interventions in this population.

Designing robot-assisted neurorehabilitation strategies for people with both HIV and stroke

There is increasing evidence that HIV is an independent risk factor for stroke, resulting in an emerging population of people living with both HIV and stroke all over the world. However, neurorehabilitation strategies for the HIV-stroke population are distinctly lacking, which poses an enormous global health challenge. In order to address this gap, a better understanding of the HIV-stroke population is needed, as well as potential approaches to design effective neurorehabilitation strategies for this population. This review goes into the mechanisms, manifestations, and treatment options of neurologic injury in stroke and HIV, the additional challenges posed by the HIV-stroke population, and rehabilitation engineering approaches for both high and low resource areas. The aim of this review is to connect the underlying neurologic properties in both HIV and stroke to rehabilitation engineering. It reviews what is currently known about the association between HIV and stroke and gaps in current treatment strategies for the HIV-stroke population. We highlight relevant current areas of research that can help advance neurorehabilitation strategies specifically for the HIV-stroke population. We then explore how robot-assisted rehabilitation combined with community-based rehabilitation could be used as a potential approach to meet the challenges posed by the HIV-stroke population. We include some of our own work exploring a community-based robotic rehabilitation exercise system. The most relevant strategies will be ones that not only take into account the individual status of the patient but also the cultural and economic considerations of their respective environment.

Lower likelihood of cardiac procedures after acute coronary syndrome in patients with human immunodeficiency virus/acquired immunodeficiency syndrome

Cardiovascular disease (CVD) is an increasing cause of morbidity and mortality in human immunodeficiency virus (HIV)-infected adults; however, this population may be less likely to receive interventions during hospitalization for acute coronary syndrome (ACS). The degree to which this disparity can be attributed to poorly controlled HIV infection is unknown.In this large cohort study, we used the National Inpatient Sample (NIS) to compare rates of cardiac procedures among patients with asymptomatic HIV-infection, symptomatic acquired immunodeficiency syndrome (AIDS), and uninfected adults hospitalized with ACS from 2009 to 2012. Multivariable analysis was used to compare procedure rates by HIV status, with appropriate weighting to account for NIS sampling design including stratification and hospital clustering.The dataset included 1,091,759 ACS hospitalizations, 0.35% of which (n = 3783) were in HIV-infected patients. Patients with symptomatic AIDS, asymptomatic HIV, and uninfected patients differed by sex, race, and income status. Overall rates of cardiac catheterization and revascularization were 53.3% and 37.4%, respectively. In multivariable regression, we found that relative to uninfected patients, those with symptomatic AIDS were less likely to undergo catheterization (odds ratio [OR] 0.48, confidence interval [CI] 0.43-0.55), percutaneous coronary intervention (OR 0.69, CI 0.59-0.79), and coronary artery bypass grafting (0.75, CI 0.61-0.93). No difference was seen for those with asymptomatic HIV relative to uninfected patients (OR 0.93, CI 0.81-1.07; OR 1.06, CI 0.93-1.21; OR 0.88, CI 0.72-1.06, respectively).We found that lower rates of cardiovascular procedures in HIV-infected patients were primarily driven by less frequent procedures in those with AIDS.

Ischemic Heart Disease in HIV: An In-depth Look at Cardiovascular Risk

Although the incidence of cardiovascular diseases classically associated with human immunodeficiency virus (HIV) has decreased considerably with antiretroviral therapy, cardiovascular risk, and especially ischemic heart disease, are higher in HIV-infected patients than in uninfected individuals. This is due to the interaction of patient-dependent factors with virus-dependent factors, as well as factors associated with antiretroviral therapy. With increasing of life expectancy and the chronicity of HIV infection, cardiovascular disease has emerged as an important cause of morbidity and mortality in HIV patients. In developed countries, the most common cardiovascular manifestation of HIV is ischemic heart disease. Currently, it is not uncommon to find HIV patients with acute coronary syndrome and, given the important pharmacokinetic interactions of antiretroviral drugs, it is important to know which cardiovascular treatments are safe in this group of patients. The ideal approach would be to mitigate the cardiovascular risk in HIV patients with specific primary prevention measures. All these issues are discussed in this review, which aims to aid clinical cardiologists faced with HIV patients with ischemic heart disease or with high cardiovascular risk in daily clinical practice.

A Review of Management of Inflammation in the HIV Population

Advancements in antiretroviral therapy have drastically increased the life expectancy for those infected with HIV. Today, a new subgroup of older patients with long-term controlled HIV exists, and its populace is continuously mounting. Therefore, it is essential to understand the enduring effects of chronic suppressed HIV infection in order to further improve HIV management in these patients. This paper will examine the role of HIV in chronic inflammation and immune dysfunction, the dynamic interaction that exists between comorbidity and HIV, and the potential consequences of long-term antiretroviral therapy in an effort to provide the best management options for the virally suppressed HIV patient.

Fifteen-Year Trends in the Prevalence of Diabetes among Hospitalized HIV-Infected Patients in Spain (1997-2012)

OBJECTIVE

To describe trends in the prevalence of diabetes among hospitalized HIV-infected patients between 1997 and 2012 in Spain and compare them with those of age- and sex-matched non-HIV-infected patients.

METHODS

The study was based on Spanish national hospital discharge data. We performed a retrospective study for the period 1997-2012. HIV infection (HIV-infected versus non-HIV-infected [control group])and calendar period in relation to widespread use of combination antiretroviral therapy (cART) (1997-1999; 2000-2003; 2004-2007 and 2008-2012), were the exposure variables The outcome variables were diagnosis of diabetes and in-hospital mortality (IHM).

RESULTS

From 1997 to 2012, we identified 91,752 cases of diabetes: 15,398 in the HIV-infected group (403,277 hospital admissions) and 76,354 in the non-HIV-infected group (1,503,467 hospital admissions). Overall, HIV-infected patients had lower prevalence values for diabetes than non-HIV-infected patients throughout the follow-up (3.8% vs. 5.1%; p<0.001). The prevalence of diabetes increased 1.56-fold among non-HIV-infected patients and 4.2-fold among HIV-infected patients. The prevalence of diabetes in females was almost twice as high in HIV-infected patients as in non-HIV-infected patients during the last study period (4.72% vs. 2.88%; p<0.001). Diabetes showed a protective effect against IHM throughout the study period (aOR = 0.70; 95%CI, 0.65-0.75).

CONCLUSIONS

During the cART era, the prevalence of diabetes has increased sharply among HIV-infected hospitalized patients compared with matched non-HIV-infected subjects. The prevalence of diabetes is rising very fast among HIV-infected women. Diabetes has a protective effect on IHM among HIV-infected patients. Nevertheless, our study has several limitations. No information is available in the database used on important sociodemographic characteristics and relevant clinical variables including duration of the HIV infection, treatments used, drug resistance, treatment adherence or CD4 count, among others. Also, it is possible that increase of diabetes prevalence could reflect the improvement in recording habits.
