People living with HIV (PLWH) beginning antiretroviral therapy (ART) retain a high burden of cytomegalovirus (CMV). CMV has been implicated in atherosclerosis in healthy adults, and a role in PLWH is plausible. Atherosclerosis has also been linked with γδ T cells and CMV seropositivity with altered γδ T cell profiles in other populations.

Globally, people living with HIV (PLHIV) are at a high risk of syphilis transmission, and Hainan Province has one of the highest syphilis rates in China. However, there is no targeted syphilis screening for HIV patients in Hainan, highlighting the need for data to guide public health interventions. This study aims to assess the incidence of seropositive syphilis and its associated factors among PLHIV.

Innovative strategies such as HIV self-testing (HIVST) are useful for identifying hard-to-reach people living with HIV/AIDS (PLHIV), especially in developing settings where considerable gaps still exist in reaching the first 95% UNAIDS target. We evaluated the effectiveness of HIVST in Cameroon using several distribution models and investigated the predictors of HIV seropositivity among self-testers. The study was conducted from 2021 to 2022 in three regions in Cameroon.

Dried blood spots from 30,815 participants aged 6 months to 15 years from the 2018 Nigeria HIV/AIDS Indicator and Impact Survey were analyzed by multiplex bead-based assay to measure immunoglobulin G (IgG) to Pf-stage-specific MSP-1, AMA-1, GLURPR0, LSA-1, and CSP. These IgG levels were analyzed by principal component analysis (PCA).

The goal of this study was to evaluate characteristics associated with Pre-exposure Prophylaxis for HIV infection (PrEP) non-adherence or discontinuation in Brazil and assess the association between these outcomes and HIV seroconversion. We used linked national dispensing and pathology data to identify people aged 14+ years initiating PrEP in 2018. We estimated non-adherence using the proportion of days covered (PDC), defining non-adherence as PDC < 60%.
