We conducted a retrospective cohort study of hospitalized persons living with HIV at the Fourth People's Hospital of Nanning, Guangxi, China, from 2018 to 2020. Kaplan-Meier analysis was used to calculate cumulative mortality rates. The Cox proportional hazards model, 1:1:1 propensity score matching (PSM), and three-group inverse probability of treatment weighting (IPTW) were used to assess the impact of anemia severity on mortality in hospitalized persons living with HIV. A total of 2,217 hospitalized persons living with HIV were included, among whom 409 (18.4%) had anemia: 50 (2.3%) with mild anemia, 174 (7.8%) with moderate anemia, and 185 (8.3%) with severe anemia. Among all AIDS-related complications, patients with severe anemia had a higher mortality rate [20.34/100 person-months, 95% confidence interval (CI): 13.29-27.39], significantly higher than that of persons living with HIV without anemia (7.74/100 person-months, 95% CI: 6.02-9.45); the adjusted hazard ratio (AHR) was 2.422, with a 95% CI of (1.500, 3.913). After PSM and IPTW analyses, results were similar, with PSM (AHR: 4.745, 95% CI: 2.231-10.091) and IPTW (AHR: 1.920, 95% CI: 1.146-3.216).

To date, no study has addressed the underlying molecular mechanisms in PWH with CRC. To explore the impact of PWH with CRC, we sequenced total RNA and DNA from individuals with HIV-negative and PWH formalin-fixed paraffin-embedded (FFPE) CRC for transcriptome and genome analyses. We performed RNA and DNA extraction from FFPE samples, library preparation, total RNA sequencing, and whole-genome sequencing. A total of 1,705 genes were found to be differentially expressed genes (DEGs), including 1,121 upregulated DEGs and 584 downregulated DEGs, in PWH compared with HIV-negative CRC. Functional pathway analysis revealed that the DEGs were enriched mainly in infectious and immune diseases and various metabolic processes. The immune infiltration results revealed that the numbers of activated dendritic cells (aDCs), natural killer T cells (NKT cells), and T follicular helper cells (Tfh cells) were greater and that the number of memory B cells was lower in patients with CRC than in PWH. Twelve hub genes involved in interferon-stimulated genes (ISGs)-IFI44, MX1, OAS1, OAS3, BST2, IFIT1, FGF2, EGF, CCL3, CCL4, SHH, and PPARG-are positively related to aDC, NKT, Tfh, and memory B cells. We found highly analogous insertions, deletions, and functional annotations of the detected single nucleotide polymorphisms and indel mutations in PWH and patients with HIV-negative CRC.

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.
