RESUMO
BACKGROUND: The rapid start of antiretroviral therapy (RSA) model initiates antiretroviral therapy (ART) as soon as possible after a new or preliminary diagnosis of HIV, in advance of HIV-1 RNA and other baseline laboratory testing. This observational study aims to determine if RSA with a single tablet regimen of bictegravir, emtricitabine, and tenofovir alafenamide (B/F/TAF) is an effective regimen for achieving viral suppression and accepted by patients at the time of diagnosis. METHODS: Adults newly or preliminarily diagnosed with HIV were enrolled from October 2018 through September 2021. Real world advantage, measured in days between clinical milestones and time to virologic suppression, associated with B/F/TAF RSA was compared to historical controls. RESULTS: All Study RSA participants (n = 45) accepted treatment at their first visit and 43(95.6%) achieved virologic suppression by week 48. Study RSA participants had a significantly shorter time (median 32 days) from diagnosis to ART initiation and virologic suppression, in comparison to historical controls (median 181 days) (n = 42). Qualitative feedback from study RSA participants showed high acceptance positive response to RSA. CONCLUSIONS: RSA is feasible and well accepted by patients in a real-world community-based clinic setting. Promoting RSA in community-based clinics is an important tool in ending the HIV epidemic.

Blacks and Hispanics/Latinos are disproportionately burdened by HIV compared to non-Hispanic Whites, as evidenced by higher HIV incidence, prevalence, and deaths attributable to AIDS. Increasing the use of novel prevention techniques such as Truvada for pre-exposure prophylaxis (PrEP) could greatly help in reducing these disparities by lowering HIV incidence among these higher risk groups. Trust in providers, which may differ by race and ethnicity, may influence willingness to take PrEP. This study explores the moderating effect of race/ethnicity on trust in one's primary care provider (PCP) on PrEP willingness. This study found a significant association between PCP trust and PrEP willingness, with those with greater trust having 3.24 times the adjusted odds of being willing to try PrEP. Results regarding the effects of race and ethnicity on these outcomes, however, were inconclusive. Results indicate the importance of fostering trust between PrEP-prescribing PCPs and their patients.

BACKGROUND: Injection drug use is a growing major public health concern. Injection drug users (IDUs) have a higher incidence of co-morbidities including HIV, Hepatitis, and other infections. An effective humoral response is critical for optimal homeostasis and protection from infection; however, the impact of injection heroin use on humoral immunity is poorly understood. We hypothesized that IDUs have altered B cell and antibody profiles. METHODS AND FINDINGS: A comprehensive systems biology-based cross-sectional assessment of 130 peripheral blood B cell flow cytometry- and plasma- based features was performed on HIV-/Hepatitis C-, active heroin IDUs who participated in a syringe exchange program (n = 19) and healthy control subjects (n = 19). The IDU group had substantial polydrug use, with 89% reporting cocaine injection within the preceding month. IDUs exhibited a significant, 2-fold increase in total B cells compared to healthy subjects, which was associated with increased activated B cell subsets. Although plasma total IgG titers were similar between groups, IDUs had significantly higher IgG3 and IgG4, suggestive of chronic B cell activation. Total IgM was also increased in IDUs, as well as HIV Envelope-specific IgM, suggestive of increased HIV exposure. IDUs exhibited numerous features suggestive of systemic inflammation, including significantly increased plasma sCD40L, TNF-α, TGF-α, IL-8, and ceramide metabolites. Machine learning multivariate analysis distilled a set of 10 features that classified samples based on group with absolute accuracy. CONCLUSIONS: These results demonstrate broad alterations in the steady-state humoral profile of IDUs that are associated with increased systemic inflammation. Such dysregulation may impact the ability of IDUs to generate optimal responses to vaccination and infection, or lead to increased risk for inflammation-related co-morbidities, and should be considered when developing immune-based interventions for this growing population.
