Highly effective antiretroviral-based HIV prevention plays an important role in ending the global HIV/AIDS epidemic. However, the sustainable control of the epidemic is hampered by unequal access to prevention options, including HIV testing, alongside with drug resistance and ongoing barriers to accessing sustainable HIV treatment. Therefore, an HIV vaccine, combined with effective prevention and treatment, remains an absolute necessity to control the epidemic.

Background: Female sex workers (FSWs) are at high risk of contracting STIs, in particular in Sub-Saharan Africa. The implementation of oral HIV pre-exposure prophylaxis provided an opportunity to draw attention to the sexual health needs of FSWs. Innovative strategies to screen for and reduce the burden of STIs is thus a priority.

Article Synopsis
  • A study assessed the quality of life (QoL) of people living with HIV in Nouvelle Aquitaine, France, revealing that while 63.5% reported good/very good QoL, significant improvements are still needed.
  • The highest QoL scores were in physical and environmental domains (both median 69), while social and psychological scores were notably lower (both median 56).
  • Factors like having three or more comorbidities, experiencing HIV-related stigma, and a monthly income below €1500 were linked to poorer QoL, highlighting the need to address both health and social issues to improve outcomes for all PLWH.

Universal HIV testing and treatment (UTT) strategies aim to optimize population-level benefits of antiretroviral treatment. Between 2012 and 2018, four large community randomized trials were conducted in eastern and southern Africa. While their results were broadly consistent showing decreased population-level viremia reduces HIV incidence, it remains unclear how much HIV incidence can be reduced by increasing suppression among people living with HIV (PLHIV).

Background: Cervical cancer, a major public health problem in many developing countries, is usually associated with a poor survival related to an advanced disease at diagnosis. In Côte d'Ivoire and other developing countries with high cervical cancer prevalence, little is known about factors associated with advanced cervical cancer stages in a context of limited access to screening services.

Methods: From May to July 2019, we conducted a cross-sectional study using a mixed, quantitative and qualitative method.

Universal HIV testing is now recommended in generalised HIV epidemic settings. Although home-based HIV counselling and testing (HB-HCT) has been shown to be effective in achieving high levels of HIV status awareness, little is still known about the cost implications of universal and repeated HB-HCT. We estimated the costs of repeated HB-HCT and the scale economies that can be obtained when increasing the population coverage of the intervention.

Article Synopsis
  • Prolonged virologic failure during 2nd-line protease inhibitor antiretroviral therapy allows researchers to examine within-host evolution of HIV-1 in chronically infected individuals.
  • The study, which analyzed whole-genome sequences from patients in a clinical trial, found significant fluctuations in variant frequencies and evidence of viral competition even with stable viral load, suggesting instability in the viral population.
  • This research highlights the genetic diversity and evolutionary dynamics of HIV-1 during treatment, offering insights that may extend to understanding other RNA viruses as well.

Introduction: Sex differences have already been reported in sub-Saharan Africa for attrition and immunological response after antiretroviral therapy (ART) initiation, but follow-up was usually limited to the first two to three years after ART initiation. We evaluated sex differences on the same outcomes in the 10 years following ART initiation in West African adults.

Methods: We used cohort data of patients included in the IeDEA West Africa collaboration, who initiated ART between 2002 and 2014.

The rate of mother-to-child transmission (MTCT) of HIV from breastfeeding is increasing relative to other causes of MTCT. Early effective preconception and antenatal antiretroviral therapy (ART) reduces intrauterine and intrapartum MTCT, whereas maternal post-partum HIV acquisition, untreated maternal HIV, and suboptimal postnatal maternal ART adherence increase the risk of MTCT through breastfeeding. Although the absolute number of cases of MTCT acquired through breastfeeding is decreasing, the rate of decrease is less than the decrease in intrauterine and intrapartum MTCT.

In light of the increasing global burden of new HIV infections, growing financial requirements, and shifting funding landscape, the global health community must accelerate the development and delivery of an HIV cure to complement existing prevention modalities. An effective curative intervention could prevent new infections, overcome the limitations of antiretroviral treatment, combat stigma and discrimination, and provide a sustainable financial solution for pandemic control. We propose steps to plan for an HIV cure now, including defining a target product profile and establishing the HIV Cure Africa Acceleration Partnership (HCAAP), a multidisciplinary public-private partnership that will catalyse and promote HIV cure research through diverse stakeholder engagement.

We investigated the effect of early antiretroviral treatment (ART) initiation on HIV status disclosure and social support in a cluster-randomized, treatment-as-prevention (TasP) trial in rural South Africa. Individuals identified HIV-positive after home-based testing were referred to trial clinics where they were invited to initiate ART immediately irrespective of CD4 count (intervention arm) or following national guidelines (control arm). We used Poisson mixed effects models to assess the independent effects of (a) time since baseline clinical visit, (b) trial arm, and (c) ART initiation on HIV disclosure (n = 182) and social support (n = 152) among participants with a CD4 count > 500 cells/mm at baseline.
