We analyzed the HIV-1 subtypes, TDR prevalence, TDR-associated mutations, and predicted drug sensitivity.

A total of nine patients infected with CRF01_AE exhibited one or more TDR mutations, including 3.6% for Protease Inhibitor (PI)-related mutations, 1.0% for NRTI-related mutations and 1.0% for NNRTI-related mutations. The most common mutation was M46L/I for PIs. Notably, TDR prevalence showed an upward trend from 2012 to 2018, with an average of 4.7%. The gradually diversified subtypes, the increased TDR prevalence, and the potential risk of transmitting drug-resistant strains to the general population highlight the necessity of TDR monitoring in MSM.

To address this, we conducted a cross-sectional study in Soweto, South Africa, assessing stated acceptability of five potential HIV cure-related research modalities and identifying associated factors. Between May and August 2024, we sampled 100 adults living with HIV who provided informed consent. Participants completed questionnaires of socio-demographics and the Theoretical Framework of Acceptability scale measuring general acceptability and seven constructs (affective attitude, burden, ethicality, perceived effectiveness, intervention coherence, self-efficacy, opportunity costs). We summarized data using descriptive statistics. We assessed factors associated with acceptability using univariate and multivariate logistic regression. We found that of 100 participants (44% female, median age 39 years), 66% were willing to accept an intervention that would allow lifelong remission (antiretroviral treatment-free control), 88% were willing if the intervention guaranteed remission for everyone treated, and 87% were willing if the intervention had minimal side effects. Total mean acceptability scores of hypothetical HIV cure-related research modalities were oral or injectable chemotherapeutics (3.8/5), intravenous or injectable antibodies (3.7/5), radiotherapy (3.3/5), transplantation (3.1/5), gene therapy (2.9/5), and across all modalities (3.4/5). Participants rated antibodies and chemotherapeutics with tied top scores for affective attitude (3.8/5) and self-efficacy (4.0/5); chemotherapeutics with top scores for perceived effectiveness (4.0/5), intervention coherence (4.1/5) and having least burden (3.2/5) and opportunity costs (3.3/5); and antibodies with the top score for ethicality (4.2/5). Acceptability was associated with non-binary gender and willingness to take an intervention achieving 2 years remission. In conclusion, people living with HIV have moderately high acceptability for oral or injectable chemotherapeutics and intravenous or injectable antibodies but would need more information about gene therapy, transplantation, and radiotherapy. Antibodies aligned highest with personal values, suggesting support for antibody research and applications.</p>","PeriodicalId":7544,"journal":{"name":"AIDS research and human retroviruses","volume":" ","pages":""},"PeriodicalIF":1.5,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144473704","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 data are presented as age-standardized rates per 100,000 inhabitants, along with corresponding uncertainty intervals (95% UI) and the relative percentage change. Globally, there was a decrease in the age-standardized incidence rate of HIV from 37.59 cases per 100,000 in 1990 to 25.24 cases per 100,000 in 2019. However, in India, it increased from 3.43 cases per 100,000 to 5.01 cases per 100,000 during the same period. There was an increase in both HIV prevalence and HIV-related death rates in India and globally. The increases in estimates were smaller for the rest of the world compared to India.

To track the evolution and epidemiological characteristics of HIV-1 genetics in Yunnan Province, this study conducted a retrospective molecular epidemiological study of HIV-1 in new infections in Yunnan Province. From the newly reported HIV-infected individuals throughout Yunnan Province from January to March 2018, cases with CD4⁺ T lymphocytes less than 200 cells/µL were excluded for BED capture enzyme immunoassay (BED-CEIA). Samples identified as recent infections by BED-CEIA were subjected to viral gene amplification to analyze the distribution characteristics of HIV-1 genotypes and the prevalence of pretreatment resistance. Of the 1,740 samples tested by BED-CEIA, 448 were identified as newly infected, and 323 were successfully genotyped; 14 HIV-1 genotypes were identified, including 2 subtypes, 11 circulating recombinant forms (CRFs), and several unique recombinant forms (URFs), of which CRF08_BC (37. 5%, 121/323), CRF07_BC (22.6%, 73/323), URFs (18.3%, 59/323), and CRF01_AE (14.9%, 48/323) were the predominant genotypes. CRF08_BC had higher proportions in the northeastern, southeastern, central, and southwestern regions of Yunnan Province than in the northwestern region and was more common in the 40-49-year age group, married, and heterosexual contacts. CRF01_AE had significantly higher proportions in the southeastern and northwestern regions and among those with homosexual contact, whereas no significant correlations were found for CRF07_BC and URFs. The overall prevalence of pretreatment resistance was 8.5% [95% confidence interval (CI): 5.5%-12.4%], with the highest proportion of resistance to nonnucleoside reverse transcriptase inhibitors (NNRTIs; 6.0%, 95% CI: 3.5%-9.4%). This study demonstrated the genetic diversity and regional and subpopulation distribution characteristics of the recently infected HIV-1 population in Yunnan Province, and that pretreatment resistance was at a moderate level, but resistance to NNRTIs needs attention.

A total of 967 longitudinal plasma specimens from 180 HIV-1 seroconverting individuals, all antiretroviral treatment (ART) naïve, from multiple countries were used to determine the MDRI, while cross-sectional plasma specimens from individuals infected for >1 year (total <i>n</i> = 1,285; <i>n</i> = 926 without AIDS; <i>n</i> = 359 with AIDS; all ART naïve) were tested to estimate the FRR. All specimens were tested by two testers and results were interpreted visually, followed by a line intensity reader. Linear interpolation and polynomial regression were used to estimate the duration of recent infection by subject. MDRI was calculated as a mean of individual duration of recency while FRR was calculated as a fraction of long-term (LT) cases that were misclassified as recent. The LT line intensity, a reflection of antibody avidity, demonstrated an overall increase over time, especially during the first year after seroconversion. The MDRI was 160 days [95% confidence interval (CI), 140-181] by linear interpolation and 167 days (95% CI, 147-187) by polynomial regression among ART-naïve cases.
