This study aims to explore the relationship between ART regimen switching history and lipid profiles in PLWH. 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). In contrast, individuals with a history of ART regimen switching had noticeably lower HDL cholesterol (HDL-C) levels [difference: 0.04; 95% confidence intervals (CI) 0.00 to 0.07]. This means that the history of switching ART regimens may be associated with lipid deterioration in PLWH.","PeriodicalId":7544,"journal":{"name":"AIDS research and human retroviruses","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143802160","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}

Curiously, even with improved CD4+ T-cell counts and low viral loads following ART, some PLWH with KS may still experience KS progression or even death and require adjuvant chemotherapy to manage their KS. 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. Innovation would be necessary to reduce costs and simplify the viral quantification assays, enabling the translation of these findings into routine clinical care, particularly in resource-limited settings.","PeriodicalId":7544,"journal":{"name":"AIDS research and human retroviruses","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143778833","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}

The study subjects were women of childbearing age infected with HIV-1 who were followed up in the county of Liangshan Prefecture from January to September 2023. Peripheral venous blood samples were collected from each subject. The samples were centrifuged to separate the plasma and blood cells for HIV-1 RNA quantitative testing and HIV-1 genotypic drug resistance testing. A total of 47 participants were included in this study. When HIV-1 RNA were <50 copies/mL and between 50 and 1,000 copies/mL, the success rate of HIV-1 DNA pol gene amplification was significantly higher than that of HIV-1 RNA pol gene amplification. Among the 47 subjects, 17 (17/47, 36.17%) indicated successfully amplified HIV-1 RNA and HIV-1 DNA genotypic drug resistance in each region simultaneously, and 9 (9/17, 52.94%) developed any degree of resistance. Among these nine cases, five had consistent resistance, while four indicated inconsistent resistance. Among the five cases with identical drug resistance, there were three cases with inconsistent drug resistance mutations (DRMs). Among the four cases with inconsistent drug resistance results, one had DRMs at the HIV-1 DNA level but no DRMs at the HIV-1 RNA level, while the other three had more DRMs at the HIV-1 RNA level than at the HIV-1 DNA level. The combination of HIV-1 RNA and HIV-1 DNA genotypic drug resistance testing can improve the drawbacks of current single HIV-1 RNA genotypic drug resistance testing, especially when HIV-1 RNA is ≤1,000 copies/mL, and significantly improve the efficiency of HIV-1 genotypic drug resistance testing.","PeriodicalId":7544,"journal":{"name":"AIDS research and human retroviruses","volume":" ","pages":"203-210"},"PeriodicalIF":1.5,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142885223","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}

In this study, we aimed to address whether HIV-1 DNA genotypic drug resistance testing could direct successfully virological suppression in patients infected with HIV-1 experiencing persistent LLV based on evidence from a cohort study. The subjects of this study were all people living with HIV-1 who received ART and followed in the Yuexi County (Liangshan, China) from December 2010 to February 2024. From June 2021 to February 2024, a total of 10 mL of peripheral blood was collected from each subject at each follow-up and separated. HIV-1 RNA and HIV-1 DNA were quantified, followed by HIV-1 genotypic drug resistance testing. ART regimens were accordingly adjusted, while follow-up tests were performed in terms of HIV-1 RNA and DNA measurements. The prevalent HIV-1 DNA drug resistance mutations (DRMs) included M184V, K103N, K101E/P, and V108I. The primary resistance mutations observed for nucleoside reverse transcriptase inhibitor (NRTI) were against abacavir, lamivudine, and emtricitabine. For non-NRTI, the primary DRMs were associated with efavirenz and nevirapine. Five out of the six patients were subjected to regimen adjustments according to HIV-1 DNA DRMs, while one patient was continuously treated with unchanged regimen. Viral suppression was achieved in all five ART-changed cases, with observation of remarkable of HIV-1 DNA decline. The ART-unchanged case showed progressive treatment failure with drastic increase of plasma HIV-1 RNA and whole blood HIV-1 DNA. For patients with LLV, HIV-1 DNA genotypic drug resistance testing directed ART regimen considerations are highly recommended for achieving viral suppression.","PeriodicalId":7544,"journal":{"name":"AIDS research and human retroviruses","volume":" ","pages":"197-202"},"PeriodicalIF":1.5,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142977190","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}

In this study, we characterize a novel HIV-1 second-generation circulating recombinant form (CRF117_0107) consisting of CRF01_AE and CRF07_BC fragments from three epidemiologically unrelated individuals infected with HIV-1. One near full-length genome (NFLG) sequence was amplified, sequenced, and spliced in two halves using RNA extracted from the plasma of a homosexual in Shenzhen, Guangdong Province. Two other NFLG sequences were obtained from the Los Alamos HIV Sequence Database under accession numbers KY201177 and MK397789, which were isolated from men who have sex with men (MSM) in Guangdong Province and Zhejiang Province, respectively. Phylogenetic analysis revealed that these NFLG sequences formed a monophyletic cluster with a high bootstrap value of 1.0. Recombination analysis demonstrated that the genome of CRF117_0107 was separated into three segments by two breakpoints. Further subregional phylogenetic analysis was performed that showed segment I+III (790-5990nt, 8295-9412nt) of CRF117_0107 originated from the CRF07_BC cluster, and Segment I+III (5991-8294nt) originated from the CRF01_AE cluster. The appearance of CRF117_0107 further highlights that HIV-1 SGR strains containing CRF01_AE and CRF07_BC will be generated more frequently and will most likely be more conducive to accelerating the spread of HIV in China.
