Abstract
Chronic anemia is more prevalent in people living with HIV (PLWH) compared to the general population. The mechanisms that drive chronic anemia in HIV are multifaceted and include functional impairment of hematopoietic stem cells, dysregulation of erythropoietin production, and persistent immune activation. Chronic inflammation from HIV infection adversely affects erythropoiesis, erythrocyte lifespan, and erythropoietin response, leading to a heightened risk of co-infections such as tuberculosis, persistent severe anemia, and increased mortality. Additionally, chronic anemia exacerbates the progression of HIV-associated nephrotoxicity and contributes to cardiovascular risk through immune activation and inflammation. This review highlights the cardinal role of chronic inflammation as a link connecting persistent anemia and cardiovascular complications in PLWH, emphasizing the need for a universal understanding of these interconnected pathways for targeted interventions.

Initial antiretroviral therapy regimen and risk of heart failure. AIDS 2024; 38:547-556.

Abstract
OBJECTIVES Heart failure risk is elevated in people with HIV (PWH). We investigated whether initial antiretroviral therapy (ART) regimens influenced heart failure risk. DESIGN Cohort study. METHODS PWH who initiated an ART regimen between 2000 and 2016 were identified from three integrated healthcare systems. We evaluated heart failure risk by protease inhibitor, nonnucleoside reverse transcriptase inhibitors (NNRTI), and integrase strand transfer inhibitor (INSTI)-based ART, and comparing two common nucleotide reverse transcriptase inhibitors: tenofovir disoproxil fumarate (tenofovir) and abacavir. Follow-up for each pairwise comparison varied (i.e. 7 years for protease inhibitor vs. NNRTI; 5 years for tenofovir vs. abacavir; 2 years for INSTIs vs. PIs or NNRTIs). Hazard ratios were from working logistic marginal structural models, fitted with inverse probability weighting to adjust for demographics, and traditional cardiovascular risk factors. RESULTS Thirteen thousand six hundred and thirty-four PWH were included (88% men, median 40 years of age; 34% non-Hispanic white, 24% non-Hispanic black, and 24% Hispanic). The hazard ratio (95% CI) were: 2.5 (1.5-4.3) for protease inhibitor vs. NNRTI-based ART (reference); 0.5 (0.2-1.8) for protease inhibitor vs. INSTI-based ART (reference); 0.1 (0.1-0.8) for NNRTI vs. INSTI-based ART (reference); and 1.7 (0.5-5.7) for tenofovir vs. abacavir (reference). In more complex models of cumulative incidence that accounted for possible nonproportional hazards over time, the only remaining finding was evidence of a higher risk of heart failure for protease inhibitor compared with NNRTI-based regimens (1.8 vs. 0.8%; P = 0.002). CONCLUSION PWH initiating protease inhibitors may be at higher risk of heart failure compared with those initiating NNRTIs. Future studies with longer follow-up with INSTI-based and other specific ART are warranted.

Abstract
Infiltration of the myocardium with various cell types, cytokines and chemokines plays a crucial role in the pathogenesis of cardiomyopathies including inflammatory cardiomyopathies and myocarditis. A more comprehensive understanding of the precise immune mechanisms involved in acute and chronic myocarditis is essential to develop novel therapeutic approaches. This review offers a comprehensive overview of the current knowledge of the immune landscape in cardiomyopathies based on etiology. It identifies gaps in our knowledge about cardiac inflammation and emphasizes the need for new translational approaches to improve our understanding thus enabling development of novel early detection methods and more effective treatments.

Abstract
OBJECTIVES Children with perinatally acquired HIV (PHIV) and taking antiretroviral therapy (ART) have a high prevalence of subclinical cardiac disease. We hypothesized that cardiac disease may be a consequence of dysregulated systemic immune activation driven by HIV infection. We examined cardiovascular and proinflammatory biomarkers and their association with echocardiographic abnormalities in children with PHIV. DESIGN Cross-sectional analysis of soluble biomarkers from a prospective cohort of children aged 6-16 years with PHIV and age-matched HIV-uninfected comparison group. METHODS Cryopreserved plasma samples were used to measure seven soluble biomarkers using multiplex bead assay (Luminex). Multivariable logistic regression assessed how biomarker levels related to cardiac abnormalities. RESULTS A total of 406 children participated in this study (195 PHIV and 211 HIV-uninfected). Mean [standard deviation (SD)] ages of PHIV and HIV-uninfected participants were 10.7 (2.6) and 10.8 (2.8) years, respectively. Plasma levels of CRP, TNF-α, ST2, VCAM-1 and GDF-15 were significantly higher in the PHIV group compared with uninfected control ( P < 0.001). Among children with PHIV, with one-unit representing one SD in biomarker level, a one-unit increase in CRP and GDF-15, was associated with increased odds of having left ventricular (LV) diastolic dysfunction [adjusted odds ratio (aOR), 1.49 (1.02-2.18; P < 0.040)] and [aOR 1.71 (1.18-2.53; P = 0.006)], respectively. Each one unit increase in GDF-15 was associated with increased odds of LV hypertrophy [aOR 1.84 (95% CI 1.10-3.10; P < 0.021)]. CONCLUSION Children with PHIV had higher levels of proinflammatory and cardiovascular biomarkers compared with HIV-uninfected children. Increased CRP and GDF-15 were associated with cardiac abnormalities in children with PHIV.

Abstract
PURPOSE OF REVIEW People with HIV continue to have an excess burden of cardiovascular disease compared to the general population. The reasons for these disparities in cardiovascular disease include HIV-specific risk enhancers, traditional atherosclerotic cardiovascular disease risk factors, and sociodemographic disparities, all of which are ripe targets for intervention. RECENT FINDINGS Accurate risk prediction of atherosclerotic cardiovascular disease remains difficult, and cardiovascular risk for people with HIV may be underestimated in the absence of HIV-specific risk enhancers. Despite this increased cardiovascular risk, people with HIV are undertreated and often placed on inadequate lipid lowering therapy. Structural racism and HIV-related stigma play a role, and provider-level and structural-level interventions to encourage early identification and treatment of persons at high risk are necessary. SUMMARY Persons with HIV should be screened with existing cardiovascular risk prediction tools, and those at high risk cardiovascular disease should be promptly referred for lifestyle and pharmacologic interventions as appropriate. System-level implementation research is ongoing in attempts to narrow the gap in cardiovascular care, particularly for vulnerable communities in low resource settings.

AMERICAN HEART JOURNAL PLUS : CARDIOLOGY RESEARCH AND PRACTICE 2022; 20:100193.

Abstract
Study objective The purpose of our study was to determine if CD4+ T-lymphocyte count (CD4 count) was inversely associated with inpatient mortality and length of stay (LOS) among patients with HIV hospitalized for acute heart failure. Design Retrospective cohort study. Setting HCA hospitals throughout the United States. Participants 1704 patients with human immunodeficiency virus (HIV) hospitalized for acute heart failure with a documented, time-updated CD4 count. Interventions Patients were categorized by CD4 count ranges consisting of >500, 200-499, <200 cells/μL. Main outcome measures A multivariable negative binomial regression was performed with CD4 count as a predictor of length of stay. Multivariable logistic regression was performed with CD4 count as a predictor of mortality. Results A CD4 count <200 cells/μL was associated with an increased length of stay compared to a CD4 > 500 cells/μL (IRR 1.24, 95 % CI: 1.11 to 1.39, P ≤ 0.01). A CD4 of 200-499 cells/μL was associated with a shorter LOS compared to a CD4 < 200 cells/μL (IRR 0.82, 95 % CI: 0.75 to 0.89, P ≤ 0.01). A CD4 < 200 cells/μL was associated with an increased mortality compared to a CD4 > 500 cells/μL (OR 3.62, 95 % CI: 1.63 to 8.05, P ≤ 0.01). CD4 count was not independently associated with in-patient mortality after adjusting for viral load. Conclusion A time-updated CD4 count <200 cells/μL on hospital admission was independently associated with increased length of stay. CD4 cell count and viral load are important markers when considering the morbidity and mortality among patients with HIV hospitalized for acute heart failure.
