Abstract Although 21% of new human immunodeficiency virus (HIV) diagnoses in the United States are in youth aged 13–24 years, adolescent awareness and uptake of the HIV prevention medication pre-exposure prophylaxis (PrEP) are low. This study explores the attitudes and challenges that adolescents face while taking PrEP. Thirty interviews were conducted with Black and Latine (we use the gender-inclusive term Latine rather than Latinx for more appropriate Spanish pronunciation) students aged 15–17 who received care at school-based health centers (SBHCs) in the Bronx, NY. Transcripts were coded inductively and deductively using thematic analysis. Most participants were unaware of PrEP, but nearly all were enthusiastic when informed about it; a majority denied that they would feel any stigma when taking PrEP. Despite this high receptivity, multiple barriers were identified, particularly confidentiality from parents, low perceived need of PrEP and concerns about daily adherence and side effects. Adolescents overall were enthusiastic about the availability of PrEP and felt it empowered them to have control over their health. SBHCs were considered trusted sources of confidential, accessible care, and we believe that they can be uniquely positioned to mitigate barriers to PrEP distribution in the future.

Abstract A strategy titled “Ending the HIV Epidemic: A Plan for America” aims to reduce human immunodeficiency virus (HIV) incidence in the United States by at least 90% by 2030, using diagnosis, treatment, and prevention strategies. Texas is a Southern state that has one of the highest numbers of new HIV diagnoses and people with HIV in the country, and where HIV disproportionately impacts minorities. We retrace the historical epidemic in its largest city, Houston, to illustrate the lessons learned and milestones accomplished, which could serve as guideposts for the future. We examine the current epidemic in Texas, including the achieved levels of HIV testing, treatment continua, and pre-exposure prophylaxis prescription, and compare and contrast these with the national estimates and Plan targets. Our findings call for urgent and accelerated expansion of efforts to end HIV in Texas.

Abstract Background Human immunodeficiency virus (HIV) pre-exposure prophylaxis (PrEP) decreases HIV transmission. Some studies have raised concerns about a potential association between the implementation of HIV PrEP and the growing incidence rates of sexually transmitted infections (STIs) in the United States. Methods We conducted a quasi-experimental (interrupted time series) analysis of STI (syphilis, gonorrhea, and chlamydia) rates before (2000–2012) and after (2013–2017) the implementation of HIV PrEP. We also performed correlations between HIV PrEP utilization and STI cases at the national (2012–2017) and state (2017) levels. We defined HIV PrEP utilization as the number of people taking tenofovir disoproxil fumarate/emtricitabine for HIV prevention. Results HIV PrEP implementation was associated with 25% (relative risk [RR] 1.254, 95% confidence interval [CI] 1.245–1.263; P < .001) and 26% (RR 1.260, 95% CI 1.257–1.264; P < .001) increases in syphilis and gonorrhea rates, respectively, and a 12% reduction in chlamydia rates (RR: 0.884, 95% CI 0.883–0.885; P < .001). HIV PrEP utilization was correlated with the numbers of syphilis, gonorrhea, and chlamydia cases (spearman coefficients 1.00, 0.94, and 0.94, respectively; P < .001, P < .01, and P < .01, respectively). At the state level, HIV PrEP was also correlated with the number of cases of syphilis, gonorrhea, and chlamydia (spearman coefficients 0.85, 0.81, and 0.85, respectively; Ps < .001 for all correlations). Conclusions The implementation and utilization of HIV PrEP in the United States were associated with increased rates of STIs. Further studies to confirm these associations and to elucidate potential causes are needed.

The Impact

Pre-exposure prophylaxis (PrEP) is integral to the US End of AIDS strategy. However, low adherence, high costs, frequent testing and monitoring side effects make delivery of PrEP complicated. Gilead has sponsored PrEP-related research efforts and access as part of its marketing efforts. We review potential conflict of interests (COI) in the scientific literature for the US PrEP related articles to understand the impact of Gilead’s corporate sponsorship.We identified 93 US PrEP articles published in the top 10 medical journals and top 10 HIV/AIDS journals in 2018. There were 289 first three and senior authors in these articles, of which, 34 (11%) declared a Gilead COI and 28 (10%) had undeclared Gilead COI. Only 10 authors accounted for 50% of the articles, with 70% of them having potential COI including receiving grants, fees and study drugs. The 93 articles were associated with 51 leading institutions (institution of three or more authors or participating institutions in a trial). Authors from 12 (24%) institutions declared an institutional Gilead COI and 22 (45%) institutions had undeclared Gilead support. Overall, of the 93 included articles, 30 (32%) had declared Gilead COI. Combining declared and undeclared COIs for authors and institutions provided an overall 83 (89%) articles with a potential Gilead COI. Of the 93 articles, 60 (71%) had favorable conclusions in 60 (71%). Declared Gilead support was significantly associated with favorable article conclusions (p<.05) but combined declared/undeclared author and/or institutional Gilead support was not associated with favorable conclusion. Nearly 90% of US PrEP articles had Gilead support and authors failed to report individual or institutional COI in 70% of articles. Direct corporate support is important for scientific research. However, Gilead’s marketing push for PrEP, undeclared COI, and potential influence of Gilead supported authors are of concern given the potential impact on the scientific discourse and the US HIV control strategy.

Abstract Background Annual human immunodeficiency virus (HIV) diagnoses in the United States (US) have plateaued since 2013. We assessed whether there is an association between uptake of pre-exposure prophylaxis (PrEP) and decreases in HIV diagnoses. Methods We used 2012–2016 data from the US National HIV Surveillance System to estimate viral suppression (VS) and annual percentage change in diagnosis rate (EAPC) in 33 jurisdictions, and data from a national pharmacy database to estimate PrEP uptake. We used Poisson regression with random effects for state and year to estimate the association between PrEP coverage and EAPC: within jurisdictional quintiles grouped by changes in PrEP coverage, regressing EAPC on time; and among all jurisdictions, regressing EAPC on both time and jurisdictional changes in PrEP coverage with and without accounting for changes in VS. Results From 2012 to 2016, across the 10 states with the greatest increases in PrEP coverage, the EAPC decreased 4.0% (95% confidence interval [CI], −5.2% to −2.9%). On average, across the states and District of Columbia, EAPC for a given year decreased by 1.1% (95% CI, −1.77% to −.49%) for an increase in PrEP coverage of 1 per 100 persons with indications. When controlling for VS, the state-specific EAPC for a given year decreased by 1.3% (95% CI, −2.12% to −.57%) for an increase in PrEP coverage of 1 per 100 persons with indications. Conclusions We found statistically significant associations between jurisdictional increases in PrEP coverage and decreases in EAPC independent of changes in VS, which supports bringing PrEP use to scale in the US to accelerate reductions in HIV infections.

Model World

We review key mathematical models of the South African human immunodeficiency virus (HIV) epidemic from the early 1990s onwards. In our descriptions, we sometimes differentiate between the concepts of a model world and its mathematical or computational implementation. The model world is the conceptual realm in which we explicitly declare the rules – usually some simplification of ‘real world’ processes as we understand them. Computing details of informative scenarios in these model worlds is a task requiring specialist knowledge, but all other aspects of the modelling process, from describing the model world to identifying the scenarios and interpreting model outputs, should be understandable to anyone with an interest in the epidemic.
