Abstract Objectives Low HIV reservoirs may be associated with viral suppression under a lower number of antiretroviral drugs. We investigated tenofovir disoproxil fumarate/emtricitabine as a maintenance strategy in people living with HIV (PLHIV) with low HIV-DNA. Methods TRULIGHT (NCT02302547) was a multicentre, open-label, randomized trial comparing a simplification to tenofovir disoproxil fumarate/emtricitabine versus a triple regimen continuation (tenofovir disoproxil fumarate/emtricitabine with a third agent, control arm) in virologically suppressed adults with HIV-DNA <2.7 log10 copies/106 PBMCs and no prior virological failure (VF). The primary endpoint (non-inferiority margin 12%) was the percentage of participants with a plasma viral load (pVL) <50 copies/mL in ITT (Snapshot approach) and PP analyses at Week 48 (W48). Results Of the 326 participants screened, 223 (68%) were randomized to the tenofovir disoproxil fumarate/emtricitabine arm (n = 113) or control arm (n = 110). At W48, the tenofovir disoproxil fumarate/emtricitabine and control arms maintained a pVL < 50 copies/mL in 100/113 (88.5%) and 100/110 (90.9%) participants, respectively (ITT difference 2.4%, 95% CI –5.9 to 10.7; PP difference 3.4%, 95% CI –4.2 to 11.0). Six VFs occurred in the tenofovir disoproxil fumarate/emtricitabine arm (two with emerging mutations M184V and K65R) versus two in the control arm (ITT difference 3.5%, 95% CI –1.9 to 9.4). All VFs were resuppressed after treatment modification. Conclusions Although non-inferiority was shown, simplification to tenofovir disoproxil fumarate/emtricitabine should not be used for most PLHIV because of a low risk of VF with resistance.

Abstract Objectives The penetration of antiretroviral drugs into deep compartments, such as the CNS, is a crucial component of strategies towards an HIV cure. This study aimed to determine CSF concentrations of bictegravir, emtricitabine and tenofovir in patients with HIV-related CNS impairment (HCI) enrolled in a real-life observational study. Methods Patients with HCI treated by optimized ART, including bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) for at least 1 month were enrolled. Plasma and CSF concentrations were measured by quality control-validated assays (LC-MS/MS). The inhibitory quotient (IQARV) was calculated as the ratio of unbound (bictegravir) or total (emtricitabine and tenofovir) concentration to half (or 90%) maximal inhibitory concentration for bictegravir (or emtricitabine and tenofovir). All numerical variables are expressed as median (range). Results Twenty-four patients (nine women) were enrolled. The age was 45 (26–68) years. Unbound bictegravir and total emtricitabine and tenofovir CSF concentrations were 4.4 (1.6–9.6), 84.4 (28.6–337.4) and 1.6 (0.7–4.3) ng/mL, respectively. The unbound bictegravir CSF fraction was 34% (15%–82%) versus 0.33% (0.11%–0.92%) in plasma. Three patients had an IQARV above unity for the three antiretrovirals. Factors positively associated with the CSF concentration (unbound for bictegravir) were age and total plasma concentration for the three antiretrovirals. Patients aged over 51 years had higher CSF concentrations (unbound for bictegravir). Conclusions We observed low CSF exposure to bictegravir, emtricitabine and tenofovir. These results suggest that BIC/FTC/TAF should be used with caution as first-line treatment for people living with HIV with HCI under 51 years of age.

ABSTRACTIntroduction: HIV/AIDS sufferers must consume antiretrovirals every day and control routinely each month to take ARVs in the hospital. The condition make patients having a risk of lost to follow up attitude. The purpose of this study was to determine the factors related to the attitude of lost to follow-up on people living with hiv/aids with arv therapy at rsud dr. soetomo surabaya. Method: This study used descriptive correlation design with a cross-sectional approach. The population were 135 patients and 100 patients were required as research participant with consequtive sampling. Independent variables were perceived susceptibility, perceived severity, perceived barrier to action, perceived benefits of action, cues to action, and self efficacy. The dependent variable was lost to follow up behavior. Data were obtained by questionnaire and analyzed with Spearman's Rho. Result: There was a relationship between perceived susceptability (p=0.002), perceived severity (p=0.025), perceived barrier to action (p=0.022) and cues to action (p=0.011) with lost to follow-up behavior. There was no correlation between perceived benefit of action (p=0.196) and self efficacy (p=0.071) with lost to follow-up behavior. Discussion: Knowledge and awareness regarding the importance taking antiretroviral drugs regularly and control routinely needs to be increased for patients with antiretroviral drugs. Further researchers are advised to conduct in-depth research (qualitative research) related to the causes of lost to follow-up behaviour thus.

IntroductionAt least 30% of people living with HIV (PLWH) infection have non-alcoholic fatty liver disease (NAFLD), which has now become a leading cause of hepatic fibrosis and cirrhosis. Management is based largely on lifestyle modifications, which are difficult to achieve, and therapeutic options are urgently needed. Maraviroc (MVC), through antagonism of CCR5 receptors, may reduce hepatic fibrosis progression and could be an effective treatment for NAFLD. However, dosing is usually two times per day, unlike most currently recommended antiretroviral therapies. This study will investigate the feasibility and acceptability of addition of MVC to combination antiretroviral therapy in PLWH and NAFLD as a treatment for NAFLD.Methods and analysisThis is a phase IV, randomised, open-label, non-invasive feasibility study. Sixty individuals with well-controlled HIV-1 and NAFLD will be recruited from UK HIV clinics and randomised 1:1 to receive either optimised background therapy (OBT) plus MVC or OBT alone. Follow-up will be every 24 weeks for 96 weeks. The primary outcome measures will include recruitment and retention rates, adverse events and adherence. Secondary outcomes will include changes in markers of hepatic fibrosis, including the Enhanced Liver Fibrosis score, median liver stiffness measurement and controlled attenuation parameter scores on Fibroscan, and quality of life assessments. Analyses will be performed according to intention-to-treat principles. For secondary outcomes, estimated differences and 95% CIs between the groups using a t-method will be presented for continuous variables and as exact 95% binomial CIs for categorical variables.Ethics and disseminationEthical approval was obtained through the London Dulwich UK Research Ethics Committee (reference 17/LO/2093). Results will be disseminated both through community groups and peer-reviewed scientific literature.Trial registration number SRCTN31461655. EudraCT number 2017-004141-24; Pre-results.

ABSTRACT A significant number of people living with human immunodeficiency virus type 1 (HIV-1) suffer from HIV-associated neurocognitive disorders (HAND). Many previous studies investigating HIV in astrocytes as a heterogenous population have established the relevance of astrocytes to HIV-associated neuropathogenesis. However, these studies were unable to differentiate the state of infection, i.e., active or latent, or to evaluate how this affects astrocyte biology. In this study, the pseudotyped doubly labeled fluorescent reporter red/green (R/G)-HIV-1 was used to identify and enrich restricted and active populations of HIV+ astrocytes based on the viral promoter activity. Here, we report that the majority of human astrocytes restricted R/G-HIV-1 gene expression early during infection and were resistant to reactivation by vorinostat and interleukin 1β. However, actively infected astrocytes were inducible, leading to increased expression of viral proteins upon reactivation. R/G-HIV-1 infection also significantly decreased the cell proliferation and glutamate clearance ability of astrocytes, which may contribute to excitotoxicity. Moreover, transcriptome analyses to compare gene expression patterns of astrocyte harboring active versus restricted long terminal repeats (LTRs) revealed that the gene expression patterns were similar and that the active population demonstrated more widespread and robust changes. Our data suggest that harboring the HIV genome profoundly alters astrocyte biology and that strategies that keep the virus latent (e.g., block and lock) or those that reactivate the latent virus (e.g., shock and kill) would be detrimental to astrocyte function and possibly augment their contributions to HAND. IMPORTANCE More than 36 million people are living with HIV-1 worldwide, and despite antiretroviral therapy, 30 to 50% of the people living with HIV-1 suffer from mild to moderate neurocognitive disorders. HIV-1 reservoirs in the central nervous system (CNS) are challenging to address due to low penetration of antiretroviral drugs, lack of resident T cells, and permanent integration of provirus into neural cells such as microglia and astrocytes. Several studies have shown astrocyte dysfunction during HIV-1 infection. However, little is known about how HIV-1 latency affects their function. The significance of our research is in identifying that the majority of HIV+ astrocytes restrict HIV expression and were resistant to reactivation. Further, simply harboring the HIV genome profoundly altered astrocyte biology, resulting in a proinflammatory phenotype and functional changes. In this context, therapeutic strategies to reactivate or silence astrocyte HIV reservoirs, without excising proviral DNA, will likely lead to detrimental neuropathological outcomes during HIV CNS infection.

Antiretroviral drugs have dramatically improved the morbidity and mortality of people living with HIV (PLWH). While current antiretroviral therapy (ART) regimens are generally well-tolerated, risks for side effects and toxicity remain as PLWH must take life-long medications. Antiretroviral drugs impact autophagy, an intracellular proteolytic process that eliminates debris and foreign material, provides nutrients for metabolism, and performs quality control to maintain cell homeostasis. Toxicity and adverse events associated with antiretrovirals may be due, in part, to their impacts on autophagy. A more complete understanding of the effects on autophagy is essential for developing antiretroviral drugs with decreased off target effects, meaning those unrelated to viral suppression, to minimize toxicity for PLWH. This review summarizes the findings and highlights the gaps in our knowledge of the impacts of antiretroviral drugs on autophagy.

AbstractSemen is important in determining HIV-1 susceptibility but it is unclear how it affects virus transmission during sexual contact. Mucosal Langerhans cells (LCs) are the first immune cells to encounter HIV-1 during sexual contact and have a barrier function as LCs are restrictive to HIV-1. As semen from people living with HIV-1 contains complement-opsonized HIV-1, we investigated the effect of complement on HIV-1 dissemination by human LCs in vitro and ex vivo. Notably, pre-treatment of HIV-1 with semen enhanced LC infection compared to untreated HIV-1 in the ex vivo explant model. Infection of LCs and transmission to target cells by opsonized HIV-1 was efficiently inhibited by blocking complement receptors CR3 and CR4. Complement opsonization of HIV-1 enhanced uptake, fusion, and integration by LCs leading to an increased transmission of HIV-1 to target cells. However, in the absence of both CR3 and CR4, C-type lectin receptor langerin was able to restrict infection of complement-opsonized HIV-1. These data suggest that complement enhances HIV-1 infection of LCs by binding CR3 and CR4, thereby bypassing langerin and changing the restrictive nature of LCs into virus-disseminating cells. Targeting complement factors might be effective in preventing HIV-1 transmission.

The success of antiretroviral treatment (ART) is threatened by the emergence of drug resistance mutations (DRM). Since Brazil presents the largest number of people living with HIV (PLWH) in South America we aimed at understanding the dynamics of DRM in this country. We analyzed a total of 20,226 HIV-1 sequences collected from PLWH undergoing ART between 2008–2017. Results show a mild decline of DRM over the years but an increase of the K65R reverse transcriptase mutation from 2.23% to 12.11%. This increase gradually occurred following alterations in the ART regimens replacing zidovudine (AZT) with tenofovir (TDF). PLWH harboring the K65R had significantly higher viral loads than those without this mutation (p < 0.001). Among the two most prevalent HIV-1 subtypes (B and C) there was a significant (p < 0.001) association of K65R with subtype C (11.26%) when compared with subtype B (9.27%). Nonetheless, evidence for K65R transmission in Brazil was found both for C and B subtypes. Additionally, artificial neural network-based immunoinformatic predictions suggest that K65R could enhance viral recognition by HLA-B27 that has relatively low prevalence in the Brazilian population. Overall, the results suggest that tenofovir-based regimens need to be carefully monitored particularly in settings with subtype C and specific HLA profiles.
