Background: Youth living with HIV (YLH) are disproportionately impacted by HIV with poor outcomes along the entire HIV care continuum. In a 2020-2022 pilot study, iCARE Nigeria, successfully tested a combination intervention incorporating mobile health technology and peer navigation to: 1) improve testing and linkage to HIV care for young men, especially young men who have sex with men (YMSM) and 2) improve medication adherence and treatment outcomes for YLH. The intervention was scaled up to 5 sites in 3 Nigerian cities.

Article Synopsis
  • Viral suppression is crucial for ending the HIV epidemic, yet youth living with HIV in Nigeria experience lower rates of viral suppression compared to adults; a study aimed to identify risk factors contributing to this issue.
  • Out of 541 participants, 40% were found to be non-suppressed; significant risk factors included substance use, missed medication doses, and self-reported barriers to taking medication, while being on a first-line regimen and having supportive social networks reduced these risks.
  • The findings highlight the importance of addressing psychosocial behaviors and medication adherence in youth with HIV to improve viral suppression rates and ultimately achieve ART goals.

Article Synopsis
  • The study investigates the role of cerebrovascular disease in HIV-associated neurocognitive disorder (HAND) among a specific black population in Nigeria, comparing participants with and without cognitive impairments using CT perfusion imaging.
  • It involved 27 HIV+ adults divided into impaired (18) and unimpaired (9) groups, measuring brain blood flow and volume across key regions, and found significant differences in regional blood flow variability between the two groups.
  • The findings suggest that CT perfusion imaging can effectively show cerebral perfusion changes linked to HAND, highlighting its potential as a resource for addressing HIV impacts in Africa, where the epidemic is most severe.

Background: Strategies to support adherence are constrained by the lack of tools to objectively monitor medication intake in low-resource settings. Pharmacologic measures are objective, but pharmacy refill data is more accessible and cost-efficient. This study compared short-term and long-term efavirenz (EFV) drug levels with pharmacy refill adherence data (PRA) and evaluated their ability to predict viral suppression among people living with HIV in Nigeria.

Importance: Nigeria has the fourth-largest HIV epidemic globally, yet high levels of social stigma inhibit HIV testing among Nigerian youths and young men who have sex with men (MSM).

Objective: To report pilot data from iCARE Nigeria (Intensive Combination Approach to Roll Back the Epidemic in Nigerian Adolescents), a combination intervention using social media and peer navigation to promote HIV testing and linkage to care among high-risk youths and young men (hereinafter referred to as young men), including predominantly young MSM.

Design, Setting, And Participants: This nonrandomized controlled study assessed an organizational and community-level 12-month, preintervention-postintervention pilot trial of a combination intervention designed to increase HIV testing uptake, increase the rate of identified seropositive cases, and improve linkage to care among young men, including MSM, using social media outreach and peer navigation.

Background: Nigeria has the second highest number of people living with HIV (PLWH) globally, and evidence-based approaches are needed to achieve national goals to identify, treat, and reduce new infections. Youth between the ages of 15-24, including young men who have sex with men (YMSM), are disproportionately impacted by the Nigerian HIV epidemic. The purpose of this study was to inform adaptation of evidence-based peer navigation and mHealth approaches (social media outreach to promote HIV testing; short messaging service text message reminders to promote HIV treatment engagement) to the local context within iCARE Nigeria, a multi-phase study designed to investigate combination interventions to promote HIV testing and care engagement among youth in Nigeria.

Article Synopsis
  • The study investigates the impact of efavirenz (EFV) on neurocognitive performance in HIV patients, focusing on genetic factors influencing drug metabolism.
  • Strong correlations were found between EFV concentrations in plasma and hair, with specific genetic variants (CYP2B6 516G>T and 983T>C) linked to higher EFV levels.
  • Surprisingly, higher EFV concentrations were tied to better neurocognitive performance, contrasting with previous findings that suggested negative effects, indicating a need for further research.

Objective: In AIDS Clinical Trials Group study A5316, efavirenz lowered plasma concentrations of etonogestrel and ethinyl estradiol, given as a vaginal ring, while atazanavir/ritonavir increased etonogestrel and lowered ethinyl estradiol concentrations. We characterized the pharmacogenetics of these interactions.

Methods: In A5316, women with HIV enrolled into control (no antiretrovirals), efavirenz [600 mg daily with nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs)], and atazanavir/ritonavir (300/100 mg daily with NRTIs) groups.

Background: Cardiovascular disease (CVD) and associated comorbidities increase the risk of cognitive impairment in persons living with human immunodeficiency virus (PLWH). Given the potential composite effect of multiple cardiovascular risk factors on cognition, we examined the ability of the Atherosclerotic Cardiovascular Disease (ASCVD) risk score and the Framingham Heart Study Global CVD risk score (FRS) to predict future cognitive function in older PLWH.

Methods: We constructed linear regression models evaluating the association between baseline 10-year cardiovascular risk scores and cognitive function (measured by a summary z-score, the NPZ-4) at a year 4 follow-up visit.

Background: Drug-drug interactions between orally administered antiretroviral therapy (ART) and hormones released from an intravaginal ring are not known. We hypothesised that ART containing either efavirenz or ritonavir-boosted atazanavir would alter plasma concentrations of vaginally administered etonogestrel and ethinylestradiol but that ART concentrations would be unchanged during use of an intravaginal ring.

Methods: We did a parallel, three-group, pharmacokinetic evaluation at HIV clinics in Asia (two sites), South America (five), sub-Saharan Africa (three), and the USA (11) between Dec 30, 2014, and Sept 12, 2016.

Objectives: To expand understanding of the virological potency of initial dolutegravir plus lamivudine dual therapy (dolutegravir/lamivudine), we compared the viral decay seen in the pilot ACTG A5353 study with the decay observed with dolutegravir plus two NRTIs in the SPRING-1 and SINGLE studies, while also exploring the impact of baseline viral load (VL).

Methods: Change in VL from baseline was calculated for timepoints shared by A5353 (n = 120, including 37 participants with pretreatment VL >100000 copies/mL), SPRING-1 (n = 51) and SINGLE (n = 417). The 95% CIs of change from baseline were determined for each observed week, using the mean log10-transformed VL, and compared between the dolutegravir/lamivudine and triple therapy groups using the Wilcoxon Rank Sum test for non-inferiority (δ = 0.

In the ASPIRE trial, antiretroviral therapy (ART) switch to dolutegravir plus lamivudine (DTG+3TC) was comparable to 3-drug ART in maintaining viral suppression by standard viral load assays. We used an ultrasensitive assay to assess whether this switch led to increased residual viremia. At entry, levels of residual viremia did not differ significantly between arms (DTG+3TC vs 3-drug ART: mean, 5.
