Many LTS are willing to participate but face barriers such as age-based exclusions, comorbidities, and trial design constraints. With over half of the people with HIV in the United States aged 50 or older, addressing these barriers is crucial to designing inclusive, equitable, and representative cure trials. We conducted 32 semi-structured interviews with LTS of HIV, aged 60 years and older, recruited through community-based organizations and research networks across the United States. Participants were diverse in age, sex, gender, race, and ethnicity. We transcribed, anonymized, and analyzed interviews thematically. Most participants expressed a willingness to participate in HIV cure research, driven by a sense of responsibility and hope for future generations. However, concerns were raised about age-based exclusions from HIV cure trials, which many participants viewed as unjust given their long-term experience with HIV and commitment to finding a cure that could potentially benefit people of their age. Additional concerns included the risks of ATIs, such as viral rebound and the development of viral resistance, along with logistical challenges, including transportation and invasiveness of certain procedures. Despite these barriers, most LTS indicated they would participate in HIV cure trials if researchers addressed their concerns about safety, accessibility, and inclusion. LTS emphasized the need for transparent communication, clear informed consent, and flexible trial designs that accommodate their needs. By addressing these concerns, researchers can engage LTS more meaningfully in HIV cure research, enriching the field and promoting more inclusive and ethical study designs.</p>","PeriodicalId":7544,"journal":{"name":"AIDS research and human retroviruses","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143972142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is a retrospective analysis of data from HIV-positive individuals aged 16-82, enrolled at Jinyintan Hospital in Wuhan, China, between January 2018 and June 2022. We investigated the potential link between their history of switching ART regimens and their lipid profiles. Locally weighted scatter plot smoother (LOESS) curves were used to depict the dynamic changes in lipid profiles over time. Linear mixed-effects models were employed to assess the differences in lipid levels between individuals with and without a history of ART switches. Out of 708 patients with HIV who began ART between January 2018 and June 2022, 207 (29%) switched regimens at least once, while 501 (71%) remained on their initial regimen throughout the study. Individuals with a history of switching ART exhibited less favorable lipid profiles as identified by LOESS analysis. Linear mixed-effects models indicate that participants who had not previously altered their ART regimens displayed notably lower levels of total cholesterol to high-density lipoprotein (HDL) ratio, total cholesterol, and triglycerides compared to those with a history of ART regimen changes (total cholesterol to HDL ratio, difference -0.19, 95% CI: -0.34 to -0.04; total cholesterol, difference -0.13, 95% CI: -0.25 to 0.00; triglycerides, difference -0.27, 95% CI: -0.43 to -0.11).

The factors associated with persistent or unresponsive KS after ART initiation remain poorly characterized, and biomarkers to identify patients at risk of KS progression are needed, particularly in resource-limited areas where access to chemotherapy is limited. Here we analyzed baseline KS tumor biopsies from PLWH with KS who required chemotherapy due to unresolved KS after ART initiation and those who did not require chemotherapy after ART initiation. By examining participant metadata and viral copy number for Kaposi sarcoma-associated herpesvirus (KSHV), HIV, cytomegalovirus, and Epstein-Barr virus and KSHV gene expression in the tumor biopsies prior to ART initiation, we identified a model of factors associated with KS progression after ART initiation, including biological sex, age, and the log ratio of KSHV/HIV copy number in the tumor. We believe that the ratio of KSHV/HIV may be linked to the cell types that each virus infects, and future work exploring the relationship between tumor and immune cells in the baseline tumors is planned.
