AI Article Synopsis
- Adolescents living with HIV (ALHIV) in rural Tanzania show a viral suppression rate of 78%, but this falls short of the UNAIDS 95% target.
- Factors positively influencing viral suppression include having a CD4 cell count of ≥500 cells/mm3 and receiving a dolutegravir-based ART regimen, while female gender correlates with lower suppression odds.
- There is only a weak to moderate consistency between different measures of treatment adherence and actual viral load suppression.
Article Abstract
Background: Adolescents living with HIV (ALHIV) in sub-Saharan Africa are affected by poor treatment outcomes, likely a consequence of poor adherence.
Objectives: To assess viral suppression rates and evaluate factors associated with achieving viral suppression and maintaining treatment adherence among ALHIV in rural Tanzania.
Methods: Cross-sectional analysis of data from the Kilombero and Ulanga Antiretroviral Cohort in Ifakara, Tanzania, including adolescents aged 10-19 years on antiretroviral treatment (ART) ≥6 months at the time point of their first viral load (VL) measurement after implementation of routine VL testing from August 2017 through December 2023. VL ≥1000 copies/ml was considered unsuppressed. We assessed agreement between adherence measures (self-report, pill box return, pill count and visual analogy scale) and viral suppression. Logistic regression was used to determine factors associated with viral suppression.
Results: Of 319 included adolescents, 159 (50%) were male, 143 (45%) aged 10-13 years, 213 (74%) had disclosed their HIV status, 72 (23%) lived ≥50 kilometers from the clinic, 161 (55%) had a WHO stage III/IV and 80 (33%) had CD4 cell counts <500 cells/mm3. Overall, 249 (78%) adolescents were virally suppressed. Factors associated with viral suppression were having a CD4 cell count ≥500 cells/mm3 (adjusted Odds Ratio (aOR) 3.48; 95% CI 1.49-8.13) versus those with a CD4 cell count <500 cells/mm3, being on a dolutegravir-based regimen (aOR 12.6; 95% CI 2.50-68.7) versus those on a NNRTI based regimen. Female gender was associated with lower odds of having viral suppression (aOR 0.41; 95%CI 0.18-0.93). There was a weak to moderate agreement between adherence measures and VL suppression.
Conclusion: Adolescents in this rural cohort remain far behind the UNAIDS 95% viral suppression target with only 78% being virally suppressed. The weak to moderate associations between adherence assessment and viral suppression. Adolescents' HIV care models need to be strengthened in order to achieve viral suppression goals in this population.

Antiretroviral therapy (ART) is needed across the lifetime to maintain viral suppression for people living with HIV. In South Africa, obstacles to reliable access to ART persist and are magnified in rural areas, where HIV services are also typically costlier to deliver. A recent pilot randomized study (the Deliver Health Study) found that home-delivered ART refills, provided at a low user fee, effectively overcame logistical barriers to access and improved clinical outcomes in rural South Africa.

Purpose Of Review: Despite decades of insights about the role of natural killer (NK) cells in HIV infection, their persistent dysregulation despite antiretroviral therapy (ART) and its pathological consequences have been incompletely delineated. In this review, we highlight recent findings on the immunophenotypic and functional alterations of NK cells during virally suppressed HIV infection and explore their potential impact on promoting non-AIDS related comorbidities among people living with HIV (PLWH).
Recent Findings: Of note are the apparent persistent activated profiles of NK cells and pathophysiological events such as endoplasmic reticulum (ER) stress in potentially driving NK cell derived inflammation and tissue destruction.
Elephant in the room: natural killer cells don't forget HIV either.

Purpose Of Review: Like elephants (and T cells), accumulating evidence suggest natural killer (NK) cells never forget. The description of adaptive or memory NK cells, which can be induced by HIV/SIV infections and vaccines and associated with protective effects in persons with HIV (PWH), has dramatically increased the interest in leveraging NK cells to prevent HIV infection or suppress HIV reservoirs. However, harnessing their full antiviral potential has been hindered by an incomplete understanding of mechanisms underlying adaptive NK cell development and infected cell recognition.

Lamivudine plus dolutegravir (3TC/DTG) and bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) regimens are commonly used as first-line treatments for people living with human immunodeficiency virus (HIV) (PLWH) worldwide. There are limited comparative data on the antiviral activity and safety between these regimens in ART-naive PLWH, particularly in China, where the 3TC/DTG regimen was integrated into first-line therapy in 2021 and gained broader adoption after its inclusion in the National Health Insurance in 2022. This study aims to provide real-world evidence comparing the 3TC/DTG regimen to the B/F/TAF regimen in ART-naive PLWH in China.

Background: Adherence to antiretroviral therapy is a critical component in achieving viral suppression in people living with HIV in addition to increasing overall quality of life. Several indirect methods have been used to measure adherence including the Simplified Medication Adherence Questionnaire (SMAQ).
Objective: The objective of this study is to evaluate the reliability and validity of the SMAQ in men living with HIV/AIDS attending a Mexican national hospital.
