Article Synopsis
- Australia struggles to effectively monitor the HIV epidemic due to insufficient population data, prompting this study to use incidence prevalence ratios (IPRs) to assess the epidemic trends among specific groups: men who have sex with men, women, and people who inject drugs.
- The study employed mathematical modeling to create IPRs from various data sources, comparing them against benchmarks based on life expectancy after HIV acquisition, illuminating trends from 2015 to 2022.
- The findings showed a significant decline in IPRs across all groups, with overall rates dropping by 80%, and many groups surpassing benchmarks, indicating a positive trend in managing HIV transmission in Australia.
While HIV infection and clonal hematopoiesis (CH) have been linked with inflammatory dysregulation and an increased risk of aging-related comorbidities, their relationship with clinical geriatric syndromes has not been well defined. In the Age-related Clonal Haematopoiesis in an HIV Evaluation Cohort (ARCHIVE) study (NCT04641013), we measure associations between HIV and CH and geriatric syndromes. Of 345 participants (176 with HIV and 169 without HIV), 23% had at least one mutation associated with CH: 27% with HIV and 18% without HIV (p = 0.

We utilised existingrandomised clinical trials (RCTs) on antiretroviral therapies (ART) in HIV-1 infection to conduct a SARS-CoV-2 serosurvey, between January and March 2021, while characterising participants' features.
Design: Cross-sectional serosurvey.
Background: The World Health Organization has endorsed single-dose human papillomavirus (HPV) vaccination, but data on the impact on HPV prevalence in high HIV burden settings are limited.
Methods: A single-dose bivalent HPV vaccine was delivered to adolescent girls in grade 10 in a schools-based campaign in 1 district in South Africa. Impact on HPV 16 and 18 prevalence was evaluated using repeat cross-sectional surveys.
Background: While people with HIV (PWH) start antiretroviral treatment (ART) regardless of CD4 count, CD4 measurement remains crucial for detecting advanced HIV disease and evaluating ART programmes. We explored CD4 measurement (proportion of PWH with a CD4 result available) and prevalence of CD4 <200 cells/µL at ART initiation within the International epidemiology Databases to Evaluate AIDS (IeDEA) global collaboration.
Methods: We included PWH at participating ART programmes who first initiated ART at age 15-80 years during 2005-2019.
