Abstract
Cardiac abnormalities were identified early in the epidemic of AIDS, predating the isolation and characterization of the etiologic agent, HIV. Several decades later, the causation and pathogenesis of cardiovascular disease (CVD) linked to HIV infection continue to be the focus of intense speculation. Before the widespread use of antiretroviral therapy, HIV-associated CVD was primarily characterized by HIV-associated cardiomyopathy linked to profound immunodeficiency. With increasing antiretroviral therapy use, viral load suppression, and establishment of immune competency, the effects of HIV on the cardiovascular system are more subtle. Yet, people living with HIV still face an increased incidence of cardiovascular pathology. Advances in cardiac imaging modalities and immunology have deepened our understanding of the pathogenesis of HIV-associated CVD. This review provides an overview of the pathogenesis of HIV-associated CVD integrating data from imaging and immunologic studies with particular relevance to the HIV population originating from high-endemic regions, such as sub-Saharan Africa. The review highlights key evidence gaps in the field and suggests future directions for research to better understand the complex HIV-CVD interactions.

Factors associated with voluntary HIV counseling and testing among young students engaging in casual sexual activity: a cross-sectional study from Eastern China. BMC Public Health 2024; 24:1109. [PMID: 38649927 PMCID: PMC11036676 DOI: 10.1186/s12889-024-18562-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2023] [Accepted: 04/09/2024] [Indexed: 04/25/2024] Open
Abstract
OBJECTIVES To investigate the factors associated with voluntary HIV counseling and testing (VCT) among young students engaging in casual sexual activity and to establish a scientific rationale for developing targeted intervention strategies for preventing HIV/AIDS in this population. METHODS Stratified cluster sampling was used to conduct a survey using questionnaires to collect demographic and behavioral information for statistical analysis. RESULTS Data from 611 young students, who reported engaging in casual sexual activity, were included in the statistical analysis. Among these, 68 (11.13%) students underwent the VCT. Among young students who engaged in casual sexual activity, those who were non-Zhejiang residents (adjusted odds ratio [aOR]: 2.11; 95% Confidence Interval [CI]: 1.17-3.80), those who had received AIDS-themed lectures or health education courses from the school in the past year (aOR = 3.96, 95% CI = 1.49-10.50), those who had received HIV risk self-assessment conducted by the school in the past year (aOR = 2.31, 95% CI = 1.17-4.59), and those who had engaged in commercial sex activity in the past year (aOR = 1.98, 95% CI = 1.07-3.66) were more inclined to have undergone VCT. Male students (aOR = 0.37, 95% CI = 0.18-0.77) and those who used condoms consistently during casual sexual activity (aOR = 0.45, 95% CI = 0.21-0.97) were less likely to undergo VCT. CONCLUSION Casual sexual activity was relatively prevalent among young students, posing a potential risk for HIV transmission. These findings will be instrumental in the development more effective HIV prevention and control strategies for young students. Additionally, it highlights the necessity of promoting and popularizing VCT among young students without Zhejiang province residency, who are involved in commercial sexual activity, and/or those who lacking HIV education. Moreover, additional research and implementation of refined HIV behavioral interventions specifically tailored to young students are necessary to enhance their awareness and knowledge of HIV prevention.

Abstract
INTRODUCTION We determined steatotic liver disease (SLD) incidence in a prospective cohort of men with HIV (MWH) and men without HIV (MWOH). METHODS Incident SLD was defined using paired noncontrast computed tomography scans performed during 2010-2013 and repeated during 2015-2017. RESULTS Of 268 men, 173 MWH and 95 MWOH, 33 had incident SLD (11.1%, incidence rate 2.4 and 2.7/100 person-years for MWH and MWOH, respectively). Overall, higher abdominal visceral adipose tissue was independently associated with increased SLD risk. In MWH, increased visceral adipose tissue, insulin resistance, chronic hepatitis B, and cumulative etravirine use were associated with SLD. DISCUSSION Metabolic factors, but not HIV, were associated with incident SLD. The high incidence rate suggests that SLD will continue to increase in PWH.

Abstract
Background The consequences of low-level viremia in people with HIV are unclear. We used data from the US Military HIV Natural History Study to examine the association of low-level viremia (LLV) and serious non-AIDS events (SNAEs). Methods Included participants initiated antiretroviral therapy after 1996 and had ≥3 viral loads (VLs) measured, using an assay with a lower limit of detection of <50 copies/mL, ≥6 months after antiretroviral therapy initiation. VLs were categorized as lower levels of LLV (51-199 copies/mL), higher level of low-level viremia (HLLV; 200-999 copies/mL), and (VF; ≥200 copies/mL on 2 or more successive determinations or a single VL ≥1000 copies/mL), and virologic suppression (VS; ie, VL <50 copies/mL). Viral blips (ie, VLs between 50 and 999 copies/mL that are preceded and succeeded by VL <50 copies/mL) were analyzed in the VS category. Cox proportional hazards models were used to examine the association of LLV and SNAEs, adjusted hazard ratios and 95% confidence intervals are presented. Results A total of 439 (17.4%) SNAEs were recorded among the 2528 participants (93% male, 40% Caucasian, 43% African American) followed for a median of 11 years. In 8.5% and 4.6% of the participants, respectively, LLV and HLLV were the highest recorded viremia strata. Compared with VS, SNAEs were associated with LLV (1.3 [1.2-1.4]), HLLV (1.6 [1.5-1.7]), and virologic failure (1.7 [1.7-1.8]). Conclusions The results of this study suggest that LLV is associated with the occurrence of SNAEs and needs further study.

Abstract
Coronary artery disease (CAD) is a common comorbidity in people with human immunodeficiency virus (HIV) (PWH) and impaired coronary endothelial function (CEF) plays a central role in the pathogenesis of CAD. Age-related impaired CEF among PWH, however, is not well characterized. We investigated the association between CEF and age in males and females with and without HIV using 3-T magnetic resonance imaging (MRI). We measured the changes in coronary cross-sectional area (CSA) and coronary blood flow during isometric handgrip exercise (IHE), an established endothelial-dependent stressor with smaller increases in CSA and coronary blood flow indicative of impaired CEF. We included 106 PWH and 82 individuals without HIV. Differences in demographic and clinical characteristics between PWH and individuals without HIV were explored using Pearson's χ2 test for categorical variables and Welch's t test for continuous variables. Linear regression models were used to examine the association between CEF and age. CEF was significantly lower in PWH as compared with individuals without HIV. Coronary endothelial dysfunction was also present at younger ages in PWH than in the individuals without HIV and there were significant differences in CEF between the PWH and individuals without HIV across age groups. Among the individuals without HIV, the percent changes in CSA were inversely related to age in unadjusted and adjusted models. There was no significant association between CEF and age in PWH. To the best of our knowledge, this is the first study to examine the relationship between age and CEF in PWH, and our results suggest that factors other than age significantly impair CEF in PWH across the life span.NEW & NOTEWORTHY This is the first study to examine the relationship between age and coronary endothelial function (CEF) in people with human immunodeficiency virus (HIV) (PWH). CEF was assessed using magnetic resonance imaging (MRI) in people with and without HIV. Although age and CEF were significantly inversely related in individuals without HIV, there was no association between age and CEF in PWH.

Abstract
Background People living with HIV (PLWHIV) are at a higher risk of developing coronary artery disease (CAD). We aimed to assess the factors associated with CAD among PLWHIV in Colombia. Methods We conducted a retrospective cohort study based on adults newly diagnosed with HIV, reported to the Colombian HIV/AIDS registry from 2018 to 2021. Baseline demographic and clinical characteristics were compared by age (<50 and ≥ 50 years). Our main outcome was the presence of CAD. Logistic regression models were used to assess the association between traditional and HIV-related factors with CAD. These associations were also evaluated in stratified models by age. Effect measures were odds ratios (OR) and their 95% confidence intervals. Results Among 36,483 PLWHIV, the frequency of CAD was 0.53% (n = 196). There was a high prevalence of impaired fasting glucose/diabetes mellitus (12.62%), overweight/obesity (27.79%), elevated LDL-c (86.69%), and hypertriglyceridemia (72.76%). Factors associated with CAD included male gender (OR: 2.01, 95% CI: 1.12-3.58), age ≥50 years (OR: 4.96, 95% CI: 3.29-7.45), lipoatrophy or lipodystrophy (OR 5.12, 95% CI: 1.12-23.33), AIDS-defining conditions (OR: 1.83, 95% CI: 1.07-3.12), obesity (OR: 2.95, 95% CI: 1.69-5.10), diabetes mellitus (OR: 2.50, 95% CI: 1.25-4.97), and renal impairment (OR: 3.15, 95% CI: 1.83-5.42). Conclusions Traditional CAD risk factors are common in PLWHIV. There were traditional and disease-specific factors associated with increased odds of CAD. These findings may aid clinicians and decision-makers in reducing the impact of CAD in PLWHIV.

Abstract
Background Incomplete antiretroviral therapy (ART) adherence has been linked to deleterious immunologic, inflammatory, and clinical consequences, even among virally suppressed (<50 copies/mL) persons with human immunodeficiency virus (PWH). The impact of improving adherence in the risk of severe non-AIDS events (SNAEs) and death in this population is unknown. Methods We estimated the reduction in the risk of SNAEs or death resulting from an increase in ART adherence by (1) applying existing data on the association between adherence with high residual inflammation/coagulopathy in virally suppressed PWH, and (2) using a Cox proportional hazards model derived from changes in plasma interleukin 6 (IL-6) and D-dimer from 3 randomized clinical trials. Comparatively, assuming 100% ART adherence in a PWH who achieves viral suppression, we estimated the number of persons in whom a decrease in adherence to <100% would need to be observed for an additional SNAE or death event to occur during 3- and 5-year follow-up. Results Increasing ART adherence to 100% in PWH who are suppressed on ART despite imperfect adherence translated into a 6%-37% reduction in the risk of SNAEs or death. Comparatively, based on an anticipated 12% increase in IL-6, 254 and 165 PWH would need to decrease their adherence from 100% to <100% for an additional event to occur over 3- and 5-year follow-up, respectively. Conclusions Modest gains in ART adherence could have clinical benefits beyond virologic suppression. Increasing ART adherence (eg, via an intervention or switch to long-acting ART) in PWH who remain virally suppressed despite incomplete adherence should be evaluated.

Abstract
Measures of viremic exposure over time, including HIV viral copy-years or durable viremic suppression, may be more relevant measures of viral load exposure for comorbid outcomes and mortality than single time point viral load measures. However, there are many subjective decisions that go into creating a cumulative variable such as HIV viral copy-years, including the appropriate anchoring point to begin accumulating exposure, the handling of viral load levels below an assay's lower limit of detection (LLD), the handling of gaps in the viral load trajectory, and when to apply the log10 transformation (before or after the accumulation calculation). Different decisions produce different values for HIV viral copy-years, and such differences could impact inferences in subsequent analyses of relationships with outcomes. In this paper, we develop several HIV viral copy-years variables that are standardized across:•Anchoring point•Handling of viral loads measured below the LLD and missing viral load measures•Application of the log10 transformation. These standardized variables may be consistently used in analyses of longitudinal cohort data. We also define a supplementary dichotomous HIV viral load exposure variable that may be used in tandem, or alternatively to, the HIV viral copy-years variables.

Abstract
People living with HIV are at increased risk for cardiovascular disease. This report summarizes our work demonstrating associations between HIV and multiple subclinical markers of cardiovascular disease risk. Some of this risk appears to be related to heightened immune activation and system inflammation that is present in people living with HIV even when there is an undetectable viral load.
