Abstract
Objective To compare patient experience in a real-life population of people living with HIV (PLWH) who received pharmaceutical care (PC) based on the Capacity-Motivation-Opportunity (CMO) model versus the traditional model. Methods Prospective cohort study in PLWH receiving either CMO-based PC or traditional PC in Spain between October 2019 and June 2021 (24 weeks), performed by the pharmacy department of 14 Spanish hospitals. Participants were adult patients with a clinical diagnosis of HIV treated with antiretrovirals who had been monitored in the participating hospital pharmacies for >1 year. Patient experience (IEXPAC questionnaire), clinical outcomes (cholesterol, triglycerides, HDL, glycated haemoglobin, and blood pressure), adherence to treatment, virologic control and patient satisfaction were determined. Results Patient experience in the CMO group at week 24 was significantly better (7.6 vs 6.9) than in the traditional group, with a higher mean improvement. Adherence was better in the CMO group, particularly with regard to concomitant medications (53.2% to 91.7%, p<0.001); no changes were observed in the traditional group. Patient satisfaction improved in the CMO group vs the traditional group (48 vs 44, p<0.001). Conclusion To our knowledge, this is the first study to compare CMO vs traditional methodology. The CMO model showed an overall improvement in real-life patient experience, satisfaction, and adherence to treatment compared to the traditional methodology.

The Role of Immunometabolism in HIV-1 Pathogenicity: Links to Immune Cell Responses. Viruses 2022; 14:v14081813. [PMID: 36016435 PMCID: PMC9415820 DOI: 10.3390/v14081813] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2022] [Revised: 08/11/2022] [Accepted: 08/15/2022] [Indexed: 11/17/2022] Open
Abstract
With the successful roll-out of combination antiretroviral treatment, HIV is currently managed as a chronic illness. Of note, immune activation and chronic inflammation are hallmarks of HIV-1 infection that persists even though patients are receiving treatments. Despite strong evidence linking immune activation and low-grade inflammation to HIV-1 pathogenesis, the underlying mechanisms remain less well-understood. As intracellular metabolism is emerging as a crucial factor determining the fate and activity of immune cells, this review article focuses on how links between early immune responses and metabolic reprograming may contribute to HIV pathogenicity. Here, the collective data reveal that immunometabolism plays a key role in HIV-1 pathogenesis. For example, the shift from quiescent immune cells to its activation leads to perturbed metabolic circuits that are major drivers of immune cell dysfunction and an altered phenotype. These findings suggest that immunometabolic perturbations play a key role in the onset of non-AIDS-associated comorbidities and that they represent an attractive target to develop improved diagnostic tools and novel therapeutic strategies to help blunt HIV-1 pathogenesis.

Abstract
HIV can traverse the BBB using a Trojan horse-like mechanism. Hidden within infected immune cells, HIV can infiltrate the highly safeguarded CNS and propagate disease. Once integrated within the host genome, HIV becomes a stable provirus, which can remain dormant, evade detection by the immune system or antiretroviral therapy (ART), and result in rebound viraemia. As ART targets actively replicating HIV, has low BBB penetrance, and exposes patients to long-term toxicity, further investigation into novel therapeutic approaches is required. Viral proteins can be produced by latent HIV, which may play a synergistic role alongside ART in promoting neuroinflammatory pathophysiology. It is believed that the ability to specifically target these proviral reservoirs would be a vital driving force towards a cure for HIV infection. A novel drug design platform, using the in-tandem administration of several therapeutic approaches, can be used to precisely target the various components of HIV infection, ultimately leading to the eradication of active and latent HIV and a functional cure for HIV. The aim of this review is to explore the pitfalls of ART and potential novel therapeutic alternatives.

Abstract
Antiretroviral therapy (ART) allows suppressed viremia to reach less than 50 copies/mL in most treated persons living with HIV (PLWH). However, the existence of PLWH that show events of persistent low-level viremia (pLLV) between 50 and 1000 copies/mL and with different virological consequences have been observed. PLLV has been associated with higher virological failure (VF), viral genotype resistance, adherence difficulties and AIDS events. Moreover, some reports show that pLLV status can lead to residual immune activation and inflammation, with an increased risk of immunovirological failure and a pro-inflammatory cytokine level which can lead to a higher occurrence of non-AIDS defining events (NADEs) and other adverse clinical outcomes. Until now, however, published data have shown controversial results that hinder understanding of the true cause(s) and origin(s) of this phenomenon. Molecular mechanisms related to viral reservoir size and clonal expansion have been suggested as the possible origin of pLLV. This review aims to assess recent findings to provide a global view of the role of pLLV in PLWH and the impact this status may cause on the clinical progression of these patients.

Silver Nanoparticles Conjugate Attenuates Highly Active Antiretroviral Therapy-Induced Hippocampal Nissl Substance and Cognitive Deficits in Diabetic Rats. J Diabetes Res 2021; 2021:2118538. [PMID: 34840987 PMCID: PMC8626174 DOI: 10.1155/2021/2118538] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2021] [Revised: 09/22/2021] [Accepted: 10/20/2021] [Indexed: 12/21/2022] Open
Abstract
BACKGROUND The application of nanomedicine to antiretroviral drug delivery holds promise in reducing the comorbidities related to long-term systemic exposure to highly active antiretroviral therapy (HAART). However, the safety of drugs loaded with silver nanoparticles has been debatable. This study is aimed at evaluating the effects of HAART-loaded silver nanoparticles (HAART-AgNPs) on the behavioural assessment, biochemical indices, morphological, and morphometric of the hippocampus in diabetic Sprague-Dawley rats. METHODS Conjugated HAART-AgNPs were characterized using FTIR spectroscopy, UV spectrophotometer, HR-TEM, SEM, and EDX for absorbance peaks, size and morphology, and elemental components. Forty-eight male SD rats (250 ± 13 g) were divided into nondiabetic and diabetic groups. Each group was subdivided into (n = 8) A (nondiabetic+vehicle), B (nondiabetic+HAART), C (nondiabetic+HAART-AgNPs), D (diabetic+vehicle), E (diabetic+HAART), and F (diabetic+HAART-AgNPs). Morris water maze, Y-maze test, and weekly blood glucose levels were carried out. Following the last dose of 8-week treatment, the rats were anaesthetized and euthanized. Brain tissues were carefully removed and postfixed for Nissl staining histology. RESULTS 1.5 M concentration of HAART-AgNPs showed nanoparticle size 20.3 nm with spherical shape. HAART-AgNPs revealed 16.89% of silver and other elemental components of HAART. The diabetic control rats showed a significant increase in blood glucose, reduced spatial learning, positive hippocampal Nissl-stained cells, and a significant decrease in GSH and SOD levels. However, administration of HAART-AgNPs to diabetic rats significantly reduced blood glucose level, improved spatial learning, biochemical indices, and enhanced memory compared to diabetic control. Interestingly, diabetic HAART-AgNP-treated rats showed a significantly improved memory, increased GSH, SOD, and number of positive Nissl-stained neurons compared to diabetic-treated HAART only. CONCLUSION Administration of HAART to diabetic rats aggravates the complications of diabetes and promotes neurotoxic effects on the experimental rats, while HAART-loaded silver nanoparticle (HAART-AgNP) alleviates diabetes-induced neurotoxicity.

Abstract
People living with HIV (PLWH) have an increased risk of cardiovascular (CV) disease, likely due to a higher prevalence of CV risk factors. We compared the age-standardized prevalence and management of CV risk factors in PLWH to that of the general population in Spain. Blood pressure, lipid, glucose, and anthropometric profiles were cross-sectionally compared along with the treatment of hypertension, dyslipidemia, and diabetes in a general population cohort and a PLWH cohort. Prevalence rates were standardized by the direct method by 10-year age groups in European standard populations and stratified by gender. We included 47,593 individuals aged 35 to 74 years, 28,360 from the general population cohort and 19,233 from the PLWH cohort. Compared to the general population, PLWH had a higher concentration of triglycerides (>35 mg/dL in women and >26 mg/dL in men) and a higher prevalence of smoking (>23% and >17%) and diabetes (>9.9% and >8.5%). The prevalence of treated diabetes, hypertension, and dyslipidemia were up to three-fold lower in both women and men living with HIV. There was a significant difference in PLWH compared to the general population in the lipid, glucose, and anthropometric profile. In addition, PLWH were less often treated for diagnosed diabetes, hypertension, and dyslipidemia.

Association of Lower Adiponectin Plasma Levels, Increased Age and Smoking with Subclinical Atherosclerosis in Patients with HIV-1 Infection. Curr HIV Res 2021; 18:292-306. [PMID: 32516102 DOI: 10.2174/1570162x18666200609114741] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2020] [Revised: 05/01/2020] [Accepted: 05/08/2020] [Indexed: 12/14/2022]
Abstract
BACKGROUND The association between subclinical atherosclerosis and traditional cardiovascular disease (CVD) risk factors, inflammatory and metabolic biomarkers has been demonstrated around the world and specifically Brazilian human immunodeficiency virus type 1 (HIV-1)- infected individuals. However, the association between subclinical atherosclerosis and these aforementioned factors combined with anti-inflammatory biomarkers has not been examined in these populations. OBJECTIVES To evaluate the association of the carotid intima-media thickness (cIMT) with CVD risk factors, inflammatory, metabolic and HIV-1 infection markers combined with adiponectin and interleukin (IL)-10 as anti-inflammatory variables. METHODS In this case-control study, 49 HIV-1-infected patients on combined antiretroviral therapy (cART) and 85 controls were compared for traditional CVD risk factors, inflammatory, metabolic, and anti-inflammatory variables. Further, we compared HIV-1-infected patients according to their cIMT (as continuous and categorized <0.9 or ≥0.9 mm variable) visualized by carotid ultrasonography doppler (USGD). RESULTS Twenty-four (48.9%) HIV-1-infected patients showed cIMT ≥0.9 mm. The patients had higher levels of C reactive protein on high sensitivity assay (hsCRP), tumor necrosis factor α, IL-6, IL-10, triglycerides, and insulin, and lower levels of adiponectin, total cholesterol and low-density lipoprotein cholesterol than controls (all p<0.05). Low levels of adiponectin were negatively associated with cIMT ≥0.9 mm (p=0.019), and explained 18.7% of the cIMT variance. Age (p=0.033) and current smoking (p=0.028) were positively associated with cIMT values, while adiponectin levels (p=0.008) were negatively associated with cIMT values; together, these three variables explained 27.3% of cIMT variance. CONCLUSION Low adiponectin was associated with higher cIMT in HIV-1-infected patients on cART. Low adiponectin levels in combination with age and smoking could explain, in part, the increased subclinical atherosclerosis observed in these patients. Adiponectin may be a good candidate for predicting subclinical atherosclerosis in the management of HIV-1-infected patients in public health care, especially where USGD is not available.

Abstract
BACKGROUND People living with HIV (PLWHIV) have a 2-fold higher risk of having a cardiovascular event than HIV-negative individuals. OBJECTIVE The objective of this article is to estimate the pooled proportion of moderate-high cardiovascular risk in PLWHIV obtained through different scores. In addition, this study also aims to establish the prevalence of dyslipidemia, smoking habits, diabetes and high blood pressure in the included studies. METHODS A bibliographic search was conducted in MEDLINE for studies on cardiovascular risk assessment in PLWHVI that took place during the period of inception to July 2018. The eligibility criteria for inclusion were: cross-sectional or longitudinal studies on HIV-positive adults in which the prevalence of moderate-high cardiovascular risk (or data to calculate it) was reported, and included at least one of the following cardiovascular risk scores: Framingham, ASCVD, D:A:D, Progetto Cuore, PROCAM, SCORE, Regicor, and World Health Organization scores. RESULTS Bibliographic search identified 278 studies. Finally, thirty-nine peer-reviewed publications were identified for a collective total of 13698 subjects. The pooled prevalence of moderate-high cardiovascular risk in PLWHIV obtained with nine different scores through random-effect modeling was 20.41% (95% CI: 16.77-24.31). The most prevalent concomitant cardiovascular risk factor was dyslipidemia (39.5%), smoking (33.0 %), high blood pressure (19.8%) and diabetes (7.24%). CONCLUSION Data obtained in this systematic review indicate that more than 1 in every five subjects with HIV have a moderate-high cardiovascular risk. In consequence, the burden of cardiovascular disease in PLWHIV represents a public health problem. There is an urgent need to develop strategies to prevent and detect cardiovascular risk effectively in PLWHIV.

Abstract
To evaluate the efficacy, safety, and tolerability of switching to a dolutegravir (DTG)-based regimen in a cohort of virological suppressed HIV-infected patients who have previously been treated with different antiretroviral combination. The dynamics of total HIV-DNA and levels of high-sensitivity c-reactive protein, interleukin-6, soluble-CD14, and D-Dimer were also analyzed. Ninety-six individuals who switched to a DTG-containing regimen were followed up for 48 weeks. HIV RNA, CD4+ T cell count, weight, and levels of laboratory parameters were recorded at baseline, after 24 and 48 weeks of treatment for all study participants. In a subgroup of patients, HIV DNA and inflammation/coagulation marker levels were also analyzed until week 24. Ninety-three out of 96 patients maintained virological suppression, including patients who switched to dual-therapy from triple-drug combination. Eighteen out of 96 patients had residual viremia at baseline, of which 13 reached the maximal viral suppression at W48. Serum creatinine levels showed a significant increase at weeks 24 and 48. A progressive reduction of total cholesterol was observed from week 24 and up to week 48. No variation in body mass index was detected. HIV DNA, inflammation, and coagulation marker levels did not significantly change during follow-up. Switching to a DTG-based regimen may be a key option for achieving and maintaining maximal virological suppression, even in patients showing residual viremia at baseline. Furthermore, the improvement in blood lipid profile and the overall tolerability observed in this study strongly support the use of these regimens in the aging HIV population.

[PMID: 32027374 DOI: 10.1093/infdis/jiaa057] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2019] [Accepted: 02/04/2020] [Indexed: 01/29/2023] Open
Abstract
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.

Abstract
Introduction: Metabolic disorders are common amongst HIV-infected patients. Data from real-life setting on the impact of DTG/ABC/3TC in virologically suppressed HIV-infected patients are scarce. Methods: We investigated the modification of metabolic profile including fasting glucose, lipid profile and markers of insulin resistance (IR) in experienced patients switching from a boosted protease inhibitors (bPI) or a non-nucleoside reverse transcriptase inhibitor (NNRTI)-based regimen to DTG/ABC/3TC in a prospective, observational, multicenter study. Results: We enrolled 131 HIV-infected patients, of whom 91 (69.5%) males, mean age was 50.5±10.6 years. CDC stage was A in 66 (50.4%) patients, of whom 91 (69.5%) had acquired HIV through sexual contacts. The previous regimen was bPI-based in 79 patients (60.3%) and NNRTI-based in 52 (39.7%). Patients switching from NNRTI showed a significant reduction at week 24 in total cholesterol (TC) and low-density lipoprotein cholesterol (LDL). Triglycerides/high-density lipoprotein cholesterol (TG/HDL) ratio, HDL, median TG and TG/HDL ratio did not show significant modification during follow-up times. Among patients switching from a bPI, we observed a significant reduction in TC and LDL at both follow-up times and a slight increase in HDL. Triglycerides/HDL ratio, median TG and TG/HDL ratio showed a decrease over time that became significant at weeks 24 and 48. Blood glucose levels did not significantly vary during the observation period in patients switching from both bPI and NNRTI-based regimens. Conclusion: Our data suggest an improvement in lipid profile and TG/HDL ratio in pretreated HIV-1-infected patients who switched to DTG/ABC/3TC over 48 weeks, especially in those previously receiving a bPI-based regimen.

Abstract
The pyrimidine nucleus is a versatile core in the development of antiretroviral agents. On this basis, a series of pyrimidine-2,4-diones linked to an isoxazolidine nucleus have been synthesized and tested as nucleoside analogs, endowed with potential anti-HIV (human immunodeficiency virus) activity. Compounds 6a-c, characterized by the presence of an ethereal group at C-3, show HIV reverse transcriptase (RT) inhibitor activity in the nanomolar range as well as HIV-infection inhibitor activity in the low micromolar with no toxicity. In the same context, compound 7b shows only a negligible inhibition of RT HIV.

Abstract
HIV-associated cerebrovascular events remain highly prevalent even in the current era of antiretroviral therapy (ART). We hypothesize that low-level HIV replication and associated inflammation endure despite antiretroviral treatment and affect ischemic stroke severity and outcomes. Using the EcoHIV infection model and the middle cerebral artery occlusion as the ischemic stroke model in mice, we present in vivo analysis of the relationship between HIV and stroke outcome. EcoHIV infection increases infarct size and negatively impacts tissue and functional recovery. Ischemic stroke also results in an increase in EcoHIV presence in the affected regions, suggesting post-stroke reactivation that magnifies pro-inflammatory status. Importantly, ART with a high CNS penetration effectiveness (CPE) is more beneficial than low CPE treatment in limiting tissue injury and accelerating post-stroke recovery. These results provide potential insight for treatment of HIV-infected patients that are at risk of developing cerebrovascular disease, such as ischemic stroke.

Abstract
Background: Endothelial activation caused by HIV-1 infection leads to release of von Willebrand factor (VWF), which enters the circulation or attaches to vessel walls and self-assembles into strings and fibers, enabling platelet adhesion; this adhesive activity is regulated by the VWF-cleaving protease ADAMTS13. Our objective was to assess VWF adhesive activity and ADAMTS13 protease activity in HIV-1 infection. Methods: We measured levels of VWF antigen, VWF activation factor (a measure of adhesive activity), ADAMTS13 antigen, ADAMTS13 activity, and apolipoprotein A1 (which interferes with VWF self-association) in serum samples from HIV-1-infected men whose infections were acute (n=10), chronic untreated (n=10), or chronic treated (n=10), compared to uninfected controls (n=10). Means across groups were compared using analysis of variance with contrasts, and Pearson correlations were calculated. Results: Plasma viral load was positively correlated with VWF adhesive activity, which was elevated in acute relative to chronic treated HIV-1 infection. ADAMTS13 antigen and activity were both positively correlated with plasma viral load, and ADAMTS13 activity was significantly higher in men with acute HIV infection than in uninfected controls, and in both acute and chronic untreated HIV infection relative to chronic treated infection. Conclusion: These findings suggest that even in the setting of increased ADAMTS13 protease activity, VWF in HIV-1 infection is hyperadhesive, which may favor development of microvascular and arterial thromboses and thereby contribute to increased cardiovascular risk in HIV-1-infected individuals.

Abstract
BACKGROUND HIV-associated atherosclerosis is a major comorbidity due, in part, to systemic effects of the virus on cholesterol metabolism. HIV protein Nef plays an important role in this pathology by impairing maturation of the main cellular cholesterol transporter ATP-Binding Cassette (ABCA) 1. ABCA1 maturation critically depends on calnexin, an integral endoplasmic reticulum membrane chaperone, and Nef binds to the cytoplasmic domain of calnexin and impairs interaction of calnexin with ABCA1. Overarching goal of the present study was to model Nef-calnexin interaction interface, and identify small molecule compounds potentially inhibiting this interaction. METHODS Molecular dynamics was utilized to build structure model of calnexin cytoplasmic domain, followed by global docking combined with application of QASDOM software developed by us for efficient analysis of receptor-ligand complexes. Structure-based virtual screening was performed for all sites identified by docking. A soluble analogue of a compound from the screening results list was tested for ability to down-regulate ABCA1. RESULTS We identified major interaction sites in calnexin and reciprocal sites in Nef. Virtual screening yielded a number of small-molecule compounds potentially blocking a calnexin site. Interestingly, one of the compounds, NSC13987, was previously identified by us as an inhibitor targeting a Nef site. An analogue of NSC13987, AMS-55, potently reversed the negative effect of Nef on ABCA1 abundance. CONCLUSIONS We have modelled Nef-calnexin interaction, predicted small molecule compounds that can potentially inhibit this interaction, and experimentally tested one of these compounds, confirming its effectiveness. These findings provide a platform for searching for new therapeutic agents to treat HIV-associated comorbidities.

Abstract
INTRODUCTION The HIV lipodystrophy syndrome is characterized by changes in metabolism, and body composition that increase cardiovascular risk of people living with HIV/AIDS (PLWHA) using highly active antiretroviral therapy (HAART). OBJECTIVE To assess the prevalence of lipodystrophy and changes in lipid and glucose metabolism in PLWHA in use of HAART. METHODS For the anthropometric evaluation we measured weight, height and abdominal circumference (AC). For the lipodystrophy evaluation we conducted physical examination (subjective) and the (objective) examination of absorptiometry with X-ray dual energy (DEXA) by fat mass ratio (FMR). We also conducted lipid profile tests and fasting glucose and used the criteria suggested by The National Cholesterol Education Program III for metabolic disorders classification. RESULTS The final sample consisted of 262 patients with a mean age of 44.3 ± 10.2 years. Lipodystrophy, according to the physical examination, was present in 47.7% (95%CI 41.7 - 53.8) of patients, while the prevalence using FMR (DEXA) was 40.8% (95%CI 33.1 - 48.5). Most (53.0%; 95%CI 47.0 - 59.1) of the patients showed increased abdominal adiposity according to AC. The most prevalent metabolic alterations were reduced HDL (67.6%; 95%CI 61.9 - 73.2) and hypertriglyceridemia (55.7%; 95%CI 49.7 - 61.7). CONCLUSION The high prevalence of lipodystrophy and changes in lipid and glucose metabolism show the importance of early intervention in this group of patients to prevent cardiovascular complications.

Abstract
Background Body fat redistribution and metabolic abnormalities found in HIV patients receiving highly active antiretroviral therapy (HAART) contribute to an atherogenic profile, increasing cardiovascular disease risk. Objective We aimed to evaluate adiposity measures/indexes and propose cutoffs associated with predictors of cardiovascular disease risk in HIV patients on HAART. Design To evaluate cardiovascular disease risk in this cross-sectional study, we conducted electrocardiogram exams and stress electrocardiography, measured the ankle brachial index and blood pressure arterial hypertension, conducted lipid biochemical tests, and measured blood glucose. We measured circumferences [waist (WC), hip, thigh, calf, neck, trunk] and skinfold thicknesses (biceps, triceps, subscapular, suprailiac), conducted bioelectrical impedance analysis (BIA), and calculated indexes [body mass index, waist-to-hip ratio, waist-to-thigh ratio, waist-to-calf ratio, waist-to-height ratio (WHtR), trunk-to-arm ratio, body mass index corrected for body fat mass, Body Adiposity Index, conicity index, body shape index, fat mass (percentage), and phase angle]. For evaluating the performance of all adiposity measures/indexes, we used receiver operating characteristic (ROC) curves. Results Measures of central adiposity WC and WHtR showed the best performances-WC area under the curve (AUC) for men: 0.83 (95% CI: 0.78, 0.89; P < 0.05); WC AUC for women: 0.86 (95% CI: 0.81, 0.91; P < 0.05); WHtR AUC for men: 0.83 (95% CI: 0.78, 0.88; P < 0.05); and WHtR AUC for women: 0.85 (95% CI: 0.80, 0.91; P < 0.05). All adiposity measures/indexes presented different cutoffs from those proposed for the HIV seronegative population. The cutoffs for WC were 87.75 cm (sensitivity: 82.2%; specificity: 75.5%) for men and 90.5 cm (sensitivity: 84.0%; specificity: 73.0%) for women. Conclusions The measures/indexes of central adiposity presented excellent associations with predictors of cardiovascular disease risk, and the use of the cutoffs proposed in the present study aims to contribute to the early identification of increasing risk of cardiovascular diseases, enabling interventions. This trial was registered at the Brazilian clinical trials registry Registro brasileiro de ensaios clínicos (Rebec) as RBR-9rcxbq.

Abstract
BACKGROUND HIV+ patients have increased their life expectancy with a parallel increase in age-associated comorbidities. OBJECTIVE To determine the effectiveness of an intensive pharmaceutical care follow-up program in comparison to a traditional model among HIV-infected patients with moderate/high cardiovascular risk. METHOD This was a multicenter, prospective, randomized study of a structured health intervention conducted between January-2014 and June-2015 with 12 months of follow-up at outpatient pharmacy services. The selected patients were randomized to a control group (usual care) or intervention group (intensive pharmaceutical care). The interventional program included follow-up of all medication taken by the patient to detect and work toward the achievement of pharmacotherapeutic objectives related to cardiovascular risk and making recommendations for improving diet, exercising, and smoking cessation. Individual motivational interview and periodic contact by text messages about health promotion were used. The primary end point was the percentage of patients who had reduced the cardiovascular risk index, according to the Framingham-score. RESULTS A total of 53 patients were included. As regards the main variable, 20.7% of patients reduced their Framingham-score from high/very high to moderate/low cardiovascular risk versus 12.5% in the control group ( P=0.016). In the intervention group, the number of patients with controlled blood pressure increased by 32.1% ( P=0.012); 37.9% of patients overall stopped smoking ( P=0.001), and concomitant medication adherence increased by 39.4% at the 48-week follow-up ( P=0.002). Conclusion and Relevance: Tailored pharmaceutical care based on risk stratification, motivational interviewing, and new technologies might lead to improved health outcomes in HIV+ patients at greater cardiovascular risk.

Abstract
Background: Since the introduction of Antiretroviral Therapy (ART), the life expectancy and health quality for patients infected with Human Immunodeficiency Virus (HIV) have significant-ly improved. Nevertheless, as a result of not only the deleterious effects of the virus itself and pro-longed ART, but also the effects of aging, cardiovascular diseases have emerged as one of the most common causes of death among these patients. Objective: The purpose of this review is to explore the new insights on the spectrum of Cardiovascu-lar Disease (CVD) in HIV infection, with emphasis on the factors that contribute to the atherosclerot-ic process and its role in the development of acute coronary syndrome in the setting of infection. Methods: A literature search using PubMed, ScienceDirect and Web of Science was performed. Ar-ticles up to Mar, 2017, were selected for inclusion. The search was conducted using MeSH terms, with the following key terms: [human immunodeficiency virus AND (cardiovascular disease OR coronary heart disease) AND (antiretroviral therapy AND (cardiovascular disease OR coronary heart disease))]. Results: Clinical cardiovascular disease tends to appear approximately 10 years before in infected in-dividuals, when compared to the general population. The pathogenesis behind the cardiovascular, HIV-associated complications is complex and multifactorial, involving traditional CVD risk factors, as well as factors associated with the virus itself - immune activation and chronic inflammation – and the metabolic disorders related to ART regimens. Conclusion: Determining the cardiovascular risk among HIV-infected patients, as well as targeting and treating conditions that predispose to CVD, are now emerging concerns among physicians.

Distinct biomarker signatures in HIV acute infection associate with viral dynamics and reservoir size. JCI Insight 2018; 3:98420.

Abstract
Estimating the size of the viral reservoir is critical for HIV cure strategies. Biomarkers in peripheral circulation may give insights into the establishment of the viral reservoir in compartments not easily accessible. We therefore measured systemic levels of 84 soluble biomarkers belonging to a broad array of immune pathways in acute HIV infection in both antiretroviral therapy-naive (ART-naive) individuals as well as individuals who began ART upon early detection of HIV infection. These biomarkers were measured longitudinally during acute and chronic infection and their relationship to viral reservoir establishment and persistence was assessed. We observed several distinct biomarker pathways induced following HIV infection such as IFN-γ-signaled chemokines, proinflammatory markers, and TNF-α-family members. Levels of several of these factors directly correlated with contemporaneous viral loads and/or frequency of peripheral blood mononuclear cells harboring HIV DNA during acute HIV infection. MCP-1, MIP-3β, sTNFR-II, and IL-10 levels prior to ART associated with HIV DNA levels after 96 weeks of treatment, suggesting a link between early immune signaling events and the establishment and persistence of the viral reservoir during ART. Furthermore, they offer potentially novel tools for gaining insight into relative reservoir size in acutely infected individuals and the potential of associated risks of treatment interruption.

[PMID: 28978797 DOI: 10.1172/jci.insight.95893] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2017] [Accepted: 09/06/2017] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND HIV-infected individuals, even well controlled with combined antiretroviral therapy (cART), have systemic inflammation and comorbidities. Substance P (SP) is an undecapeptide, which mediates neurotransmission and inflammation through its cognate neurokinin 1 receptor (NK1R). Plasma SP levels are elevated in HIV-infected individuals. The FDA-approved antiemetic aprepitant, an NK1R antagonist, has anti-HIV effects and antiinflammatory actions. We evaluated the safety, pharmacokinetics, and antiinflammatory properties of aprepitant in HIV-positive individuals receiving cART. METHODS We conducted a phase 1B study of 12 HIV-positive individuals on a ritonavir-containing regimen (HIV viral load less than 40 copies/ml and CD4 > 400 cells/μl). Participants received open-label aprepitant 375 mg per day for 28 days and were followed for an additional 30 days. Changes in plasma levels of proinflammatory markers were assessed using flow cytometry, ELISA, luminex, and SOMAscan assays. RESULTS The mean peak aprepitant plasma concentration was 30.7 ± 15.3 μg/ml at day 14 and 23.3 ± 12.3 μg/ml at day 28. Aprepitant treatment resulted in decreased plasma SP levels and affected 176 plasma proteins (56 after FDR) and several metabolic pathways, including inflammation and lipid metabolism. No change in soluble CD163 was observed. Aprepitant treatment was associated with a moderate increases in total and HDL cholesterol and affected select hematologic and metabolic markers, which returned to baseline levels 30 days after aprepitant treatment was stopped. There were 12 mild and 10 moderate adverse events (AE). CONCLUSIONS Aprepitant is safe and well tolerated. The antiinflammatory properties of aprepitant make it a possible adjunctive therapy for comorbid conditions associated with HIV infection. TRIAL REGISTRATION ClinicalTrials.gov (NCT02154360).

Abstract
Background We present a small longitudinal study of how demographic factors and persistent burdens of HIV and cytomegalovirus (CMV) influence cardiovascular health in young adults beginning ART in an inner-city clinic in Jakarta, Indonesia. Methods ART-naïve HIV patients [n = 67; aged 31 (19 to 48) years] were enrolled in the JakCCANDO Project. Echocardiography and carotid Doppler ultrasonography were performed before ART (V0) and after 3, 6, and 12 months (V3–12). Antibodies reactive with CMV lysate or IE-1 protein were assessed at each timepoint and CMV DNA was identified at V0. Results Markers of adverse cardiovascular prognosis [left ventricular mass index, ejection fraction and carotid intimal media thickness (cIMT)] were similar to healthy controls, but increased at V12. Internal diameters of the carotid arteries and systolic blood pressure correlated with HIV disease severity at V0, but cardiac parameters and cIMT did not. E/A ratios (left ventricular diastolic function) were lower in patients with CMV DNA at V0, but this effect waned by V6. Levels of antibody reactive with CMV IE-1 correlated inversely with CD4 T cell counts at V0, and levels at V6–V12 correlated directly with the right cIMT. Conclusions Overall the severity of HIV disease and the response to ART have only subtle effects on cardiovascular health in this young Asian population. CMV replication before ART may have a transient effect on cardiac health, whilst antibody reactive with CMV IE-1 may mark a high persistent CMV burden with cumulative effects on the carotid artery.

Abstract
BACKGROUND Persistent residual viremia (RV) and low grade inflammation and immune activation have been associated with non-AIDS defining events. The impact of persistent RV and HIV-DNA load on immune activation/inflammation remains unclear. The purpose of this study was to gain new insights into the relation between viremia, markers of inflammation and HIV-DNA levels. METHODS Three hundred and twenty-one HIV-infected patients were studied. A retrospective analysis of viremia values, prospectively collected for 48 months, was performed. Patients were separated into three groups: 113 TND (Target Not Detected, patients with sustained undetectable viremia); 113 RV (Residual Viremia, patients who had at least three detectable viral load (VL) values <37 copies/ml); 95 LLV (Low Level Viremia, patients with at least two VL values >37 but <200 copies/ml). HIV-DNA, TNF-α, IL-6 and sCD14 were analyzed. RESULTS HIV-DNA, sCD14 and TNF-α were significantly lower in the TND group than in the RV and LLV groups. In addition, RV patients showed lower levels of HIV-DNA and sCD14 than LLV individuals. HIV-DNA load was not related to markers of inflammation. The ordinal logistic analysis showed that two independent variables were significantly associated with VL pattern: sCD14, HIV-DNA. In addition NRTIs plus NNRTIs and NRTIs plus PIs were negatively associated to VL pattern compared to INI-containing regimen. CONCLUSIONS Persistent undetectable viremia was associated with lower levels of inflammatory markers and HIV-DNA. However, the lack of normalization of these biomarkers in the TND group and the fact that HIV-DNA load was not associated with inflammation strongly suggest that other mechanisms play a major role in maintaining inflammation over time.

Abstract
Human immunodeficiency virus (HIV) infects millions of people worldwide, and new cases continue to emerge. Once infected, the virus cannot be cleared by the immune system and causes acquired immunodeficiency syndrome. Combination antiretroviral therapeutic regimen effectively suppresses viral replication and halts disease progression. The treatment, however, does not eliminate the virus-infected cells, and interruption of treatment inevitably leads to viral rebound. The rebound virus originates from a group of virus-infected cells referred to as the cellular reservoir of HIV. Identifying and eliminating the HIV reservoir will prevent viral rebound and cure HIV infection. In this review, we focus on a recently discovered HIV reservoir in a subset of CD4+ T cells called the follicular helper T (TFH) cells. We describe the potential mechanisms for the emergence of reservoir in TFH cells, and the strategies to target and eliminate this viral reservoir.

Antiretroviral Treatment with Efavirenz Disrupts the Blood-Brain Barrier Integrity and Increases Stroke Severity. Sci Rep 2016; 6:39738.

Abstract
The introduction of antiretroviral drugs (ARVd) changed the prognosis of HIV infection from a deadly disease to a chronic disease. However, even with undetectable viral loads, patients still develop a wide range of pathologies, including cerebrovascular complications and stroke. It is hypothesized that toxic side effects of ARVd may contribute to these effects. To address this notion, we evaluated the impact of several non-nucleoside reverse transcriptase inhibitors (NNRTI; Efavirenz, Etravirine, Rilpivirine and Nevirapine) on the integrity of the blood-brain barrier, and their impact on severity of stroke. Among studied drugs, Efavirenz, but not other NNRTIs, altered claudin-5 expression, increased endothelial permeability, and disrupted the blood-brain barrier integrity. Importantly, Efavirenz exposure increased the severity of stroke in a model of middle cerebral artery occlusion in mice. Taken together, these results indicate that selected ARVd can exacerbate HIV-associated cerebrovascular pathology. Therefore, careful consideration should be taken when choosing an anti-retroviral therapy regimen.
