PURPOSE OF REVIEW: To describe models of integrated and co-located care for opioid use disorder (OUD), hepatitis C (HCV), and HIV. RECENT FINDINGS: The design and scale-up of multidisciplinary care models that engage, retain, and treat individuals with HIV, HCV, and OUD are critical to preventing continued spread of HIV and HCV. We identified 17 models within primary care (N = 3), HIV specialty care (N = 5), opioid treatment programs (N = 6), transitional clinics (N = 2), and community-based harm reduction programs (N = 1), as well as two emerging models...

BACKGROUND: Safe and effective use of pre-exposure prophylaxis (PrEP) depends on retention in care after initial engagement. SETTING: The United States PrEP Demonstration Project offered daily oral tenofovir/emtricitabine to participants in San Francisco, Miami, and Washington, D.C. for 48 weeks from 2012-2014. METHODS: Demo Project participants' patterns of retention were assigned to one of three categories: early loss to follow-up (ELTF) within the first 12 weeks of the study, retention throughout the study, or intermittent retention in which missed or delayed visits resulted in gaps in medication availability...

EDITORIAL
M Hull, Dhs Tan
Human immunodeficiency virus (HIV) infection continues to disproportionately affect vulnerable populations in Canada; particularly men who have sex with men (MSM). Novel HIV prevention strategies have recently expanded from the use of non-occupational post-exposure prophylaxis (nPEP) after high risk exposures to the use of pre-exposure prophylaxis (PrEP) in which individuals reduce risk of HIV infection through use of combination antiretrovirals taken prior to risk exposure. With approval of tenofovir/emtricitabine (TDF/FTC) for use as PrEP only in early 2016, and with limited public funding to date, uptake in Canada is in its preliminary stages...

BACKGROUND: Evidence is lacking regarding whether vaginal pre-exposure prophylaxis with topical tenofovir (TFV) reduces the risk of rectal HIV acquisition. SETTING: Bronx, NY. METHODS: MTN-014 was a phase 1, cross-over, randomized sequence trial comparing the cross-compartment pharmacokinetics and pharmacodynamics of daily TFV reduced-glycerin 1% gel after 14 days each of rectal and vaginal application, with directly observed dosing and a 6-week washout period between phases...

BACKGROUND: Pre-exposure prophylaxis (PrEP) with tenofovir disoproxil fumarate (TDF) and emtricitabine (FTC) is becoming increasingly adopted for HIV prevention. Tenofovir can cause proximal tubular damage and chronic kidney disease in HIV-infected persons, but little is known regarding its nephrotoxic potential among HIV-uninfected persons. In this study, we evaluated the effects of PrEP on urine levels of the following: α1-microglobulin (α1m), a marker of impaired tubular reabsorption; albuminuria, a measure of glomerular injury; and total proteinuria...

Men who have sex with men (MSM), who have heterogeneous HIV-acquisition risks are not specifically targeted in Kenyan pre-exposure prophylaxis (PrEP) guidelines. We used data from an open cohort, which followed 753 initially HIV-negative MSM participants for more than 1378.5 person-years, to develop an empiric risk score for targeting PrEP delivery. Independent predictors of incident HIV-1 infection in this cohort were an age of 18-24 years, having only male sex partners, having receptive anal intercourse, having any unprotected sex, and having group sex...

BACKGROUND: Global guidelines recommend pre-exposure prophylaxis (PrEP) use by women at risk for HIV, including during pregnancy, a period with heightened HIV risk. However, data to support safety of PrEP use during pregnancy are limited, particularly from women using PrEP throughout pregnancy. METHODS: In an open-label delivery study of PrEP integrated with ART for high risk HIV serodiscordant couples in Kenya and Uganda (the Partners Demonstration Project), women who became pregnant while using PrEP were offered the option to continue PrEP throughout pregnancy...

OBJECTIVE: HIV pre-exposure prophylaxis (PrEP) use may lead to higher STI incidence via behavioral risk compensation. We examined changes in sexual behaviour between baseline and six months after PrEP initiation among men who have sex with men (MSM) and transgender women (TGW). DESIGN: Prospective, open-label demonstration study at a large sexually transmitted infections (STI) clinic in Amsterdam, the Netherlands. METHODS: Participants answered questions about sexual behaviour in the preceding three months, including number of anal sex partners and frequency of anal sex with and without condom by partner type and were tested for STI...

This update to the document on antiretroviral therapy (ART) in adults, which has been prepared jointly by GeSIDA and the Spanish National AIDS Plan for the last two decades, supersedes the document published in 2017.1 The update provides physicians treating HIV-1-infected adults with evidence-based recommendations to guide their therapeutic decisions. The main difference with respect to the previous document concerns recommended initial ART regimens, only three of which are maintained as preferential. All three include dolutegravir or raltegravir, together with emtricitabine/tenofovir alafenamide or abacavir/lamivudine...

HIV acquisition during pregnancy and breastfeeding significantly contributes toward paediatric HIV infection; however, little is known about risk behaviours in HIV-uninfected pregnant and postpartum women. We conducted twenty-six in-depth-interviews between July and December 2016 using a semi-structured interview guide among HIV-uninfected pregnant and recently postpartum women at-risk of HIV acquisition (defined as reporting ≥1 of the following: partner's serostatus unknown or HIV-infected, recent condomless sex in pregnancy, and/or alcohol use during pregnancy) who attended primary healthcare services...

HIV-1 infection is most commonly transmitted by sexual contact across mucosal surfaces. Information on concordance in drug resistance profile between blood plasma and anogenital compartments in resource-limited settings is limited. We aimed to determine discordances in genotypic drug resistance-associated mutations (DRAMs) between blood plasma and semen or rectal secretions among newly diagnosed, antiretroviral therapy (ART)-naïve, HIV-1-infected Thai men who have sex with men (MSM). Blood plasma, semen, and rectal secretions of HIV-1-infected Thai MSM enrolled from the Test and Treat cohort were tested for genotypic mutations in the reverse transcriptase and protease genes...

Qualitative studies suggest that social relationships play an important role in HIV pre-exposure prophylaxis (PrEP) use, but there have been few quantitative assessments of the role of social relationships in PrEP uptake or adherence. We examined the association between disclosure of study participation or LGBT identity and PrEP use in the 1603 HIV-negative participants enrolled in the iPrEx OLE study. We also evaluated the association between LGBT social group involvement and PrEP use. Study participation disclosure to parents and LGBT identity disclosure to anyone in a participant's social network were associated with greater PrEP uptake...

PURPOSE OF REVIEW: We reviewed the HIV and opioid literature relevant to harm reduction strategies for those with criminal justice experience. RECENT FINDINGS: Opioid use in the United States has risen at an alarming rate recently. This has led to increased numbers of people who inject drugs, placing new populations at risk for HIV, including those who have criminal justice experience. In recent years, there has been a gradual decrease in the number of individuals under the supervision of the criminal justice system...

HIV transmission within stable heterosexual HIV serodiscordant couples accounts for almost half the new incident infections in South Africa and Uganda. Advances in HIV prevention provide opportunities to reduce transmission risk within serodiscordant partnerships (e.g., antiretroviral treatment (ART), pre-exposure prophylaxis (PrEP), medical male circumcision, and couples-based HIV counselling and testing). These interventions require a clinical encounter with a provider who recognises prevention opportunities within these partnerships...

Men who have sex with men (MSM) commonly use inhaled nitrites, or poppers, though their use is a risk factor HIV seroconversion. Pre-exposure prophylaxis, or PrEP, is effective for HIV prevention, but is not widely used, and little is known regarding PrEP use and acceptability among MSM who use inhaled nitrites. We surveyed 580 MSM in Paris, France in 2016 about popper use, sexual behaviors including condomless anal intercourse (CAI), serosorting, and sexual positioning, PrEP use, PrEP candidacy, and interest in alternate PrEP delivery modalities...

Background: The PrEPX trial provided HIV pre-exposure prophylaxis (PrEP) to 2600 people in Victoria, Australia. To determine participants' HIV risk, PrEPX used six eligibility criteria derived from the Australian PrEP guidelines, based on the CDC PrEP guidelines. Participants who fulfilled no eligibility criteria could be enrolled if clinically assessed to need PrEP. This study evaluated whether PREPX eligibility criteria correlated with biological HIV risk markers, namely syphilis, anorectal chlamydia or anorectal gonorrhoea (STIs)...

Over the past 15 years, a significant increase in new HIV/AIDS diagnoses has been observed in the elderly population. This new epidemiological shift has been attributed to a longer sex life, lifestyle and changes in sexual behavior, poor sexual health education, and misconceptions about the absence of sexually transmitted disease in later life. Although many biomedical and behavioral interventions have proven useful to prevent sexually transmitted infections and HIV, pre-exposure prophylaxis (PrEP) has been shown to be the most successful biomedical intervention to prevent HIV in high-risk individuals...

As oral tenofovir-based regimens for pre-exposure prophylaxis (PrEP) are adopted as standard of care for HIV prevention, their utilization in clinical trials among women in southern Africa will require an accurate estimate of oral PrEP efficacy in this population. This information is critical for women in choosing this prevention strategy, and in public health policy making. Estimates of the efficacy of oral pre-exposure prophylaxis (PrEP) regimens containing tenofovir have varied widely across trials that enrolled women, with some studies reporting high efficacy and others reporting no efficacy...

Understanding pre-exposure prophylaxis (PrEP) discontinuation is key to maximizing its effectiveness at the individual and population levels. Data came from the RADAR cohort study of MSM aged 16-29 years, 2015-2017. Participants included those who reported past 6-month PrEP use and discontinued its use by the interview date. Of the 197 participants who had used PrEP in the past 6 months, 65 discontinued use. Primary reasons for PrEP discontinuation included trouble getting to doctor's appointments (14, 21...

The goal of this work is to better understand utilization and uptake of pre-exposure prophylaxis (PrEP) among young men who have sex with men (YMSM) and transgender women (TGW). We assessed trends and correlates of PrEP use and adherence across three time points of longitudinal data collection among 885 YMSM and TGW (aged 16-29) from the RADAR cohort in Chicago, 2015-2017. Past 6-month PrEP use increased across three visits: from 6.6 to 17.5%. In multivariable models, past 6-month PrEP use was significantly associated with participation in condomless sex, having more sexual partners, and older age...
