ABSTRACTIntroduction:Scientific evidence supports the sinergy between biomedical and behavioral interventions aimed at preventing the transmission of HIV as a strategy to eradicate AIDS.Objective:To characterize comparatively the benefits from biomedical and behavioral interventions to prevent HIV transmission.Methods:Narrative review. We performed a comparative analysis of the benefits of studied interventions by means of estimating the number needed to treat (NNT). Evaluated interventions: counseling activities for behavior change to prevent exposure to HIV; antiretroviral pre-exposure prophylaxis (PrEP) and antiretroviral post-exposure prophylasis (PEP) for HIV and treatment of serodiscordant couples as a strategy for prevention of HIV transmission (TasP).Results:counseling interventions and TasP have smaller NNTs, equal to, respectively, 11 (95%CI 9 - 18) at 12 months and 34 (95%CI 23 - 54) in 42 months comparatively to PrEP interventions, that resulted in 41 (95%CI 28 - 67) individuals receiving antiretrovirals in order to prevent one case of HIV infection at 36 months for men and serodiscordant couples. PEP interventions are associated with protective effects estimated at 81%. Lack of trials evaluating PEP prevents estimate of NNT.Conclusion:The estimate of the NNT can be a helpful parameter in the comparison between the effectiveness of different behavioral and biomedical HIV prevention strategies. Studies evaluating the benefit and safety of combined behavioral and biomedical interventions are needed, especially considering the attributable fraction of each component. Integration of behavioral and biomedical interventions is required to achieve complete suppression of the virus, and thus reducing viral replication, infectivity and the number of cases.

Abstract Biomedical HIV prevention strategies for primary or secondary prevention of HIV transmission can be seen as an adjunct to behavioral prevention approaches. These interventions include vaccination, female controlled vaginal microbicides, male circumcision, treatment of sexually transmitted infections that cause genital ulceration, Pre-Exposure Prophylaxis (PREP) and Post-Exposure Prophylaxis (PEP). This article reviews results from recent randomized controlled trials of novel biomedical prevention approaches and discusses interpretation of the results. The only intervention consistently demonstrating reductions in HIV transmission was adult male circumcision in Sub-Saharan Africa. Results of PREP trials will be available in the next several years.

Men’S Involvement

Background: Desires to have children are not lessened by a woman’s HIV status. Couples may lack information to conceive safely, and men may be especially uninformed. This study examined reproductive intentions, practices, and attitudes among men in HIV-infected couples, including attitudes regarding the perceived risk of vertical and horizontal transmission, safer conception, and preconception planning. Methods: Men ( n = 12) in HIV-infected couples were interviewed regarding reproductive intentions, attitudes, and knowledge and qualitative assessments were coded for dominant themes. Results: Themes primarily addressed concerns about the health of the baby, men’s involvement in pregnancy, safer conception, concerns about HIV transmission and antiretroviral therapy, and HIV infection. Men lacked information on safer conception and newer HIV prevention strategies, such as pre-exposure prophylaxis (PrEP). Discussion: Gaps in knowledge regarding preconception practices among men in HIV-infected couples were identified. Results highlight men’s desire for involvement in preconception planning, and opportunities for providers to facilitate this practice and to increase patient education and the use of PrEP are discussed.

ABSTRACTIntroduction:The use antiretroviral reduces the sexual transmission of HIV, expanding interventions for serodiscordant couples.Objective:This article aims to review the use of antiretroviral and other prevention interventions among serodiscordant couples and to analyze its use in Brazil.Methods:A retrospective review was performed through the MEDLINE database and bases included in the Biblioteca Virtual em Saúde.Results:The articles recovered exhibit four main strategies: (1) condom; (2) reduction of risks in sexual practices; (3) use of antiretrovirals, particularly early initiation of antiretroviral therapy (TASP) and pre-exposure prophylaxis (PrEP); (4) risk reduction in reproduction.Discussion:TASP is highly effective in reducing sexual transmission, PrEP was tested in serodiscordant couples and both reduce the sexual transmission risk in different sexual practices, enabling individualized prevention strategies.Conclusions:When used in combination, antiretrovirals and sexual practices with condoms offer greater efficacy than any single strategy. The combined use of new and old strategies allows us to build a prevention policy for all.

Introduction Knowing the factors associated with HIV transmission is necessary in order to design preventive programmes tailored to the epidemiological situation in each region and population. Aim Our objective was to study the sociodemographic, clinical and behavioural characteristics of men who have sex with men (MSM) who were newly diagnosed with HIV infection. Methods We carried out an observational, descriptive, study on all MSM newly diagnosed with HIV infection in one clinic for sexually transmitted infections (STI) and HIV clinic in Madrid between 2014 and 2019. Information on sociodemographic, clinical, and behavioural characteristics of participants per year of diagnosis was collected. Results We detected a total of 1,398 people with HIV infection, 253 of whom were recent seroconverters (rSCV) with a median duration of documented seroconversion of 6 months. From the total, 97.9% infections were sexually transmitted and 2.1% involved injected drugs, i.e. slam practices. The average age was 32.9 years (range: 15.6–74.9), 51.8% were Spanish and 40% Latin American. These diagnoses decreased in Spanish people and increased in Latin Americans during the study period. Of the rSCV, 73.9% had condomless sex under the influence of drugs and 28.9% participated in chemsex sessions. Apps were used by 92.6% rSCV for sexual encounters and 70.4% of them attributed HIV transmission to their use. Conclusions Combination of HIV prevention strategies, as pre-exposure prophylaxis, should be reinforced among young MSM, especially those born in Latin America, those who use drugs for sex, and those who use apps in search of sexual contacts.

Lack Of Knowledge

Abstract Background Screening, condom use and post-exposure prophylaxis (PEP) are among existing HIV prevention strategies. However, efficient use of these strategies requires that patients have an adequate knowledge of HIV transmission routes and awareness of risk behaviors. This study aimed to assess knowledge about HIV transmission among patients who attended a free HIV and sexually transmitted infection (STI) screening center in Paris, France, and to explore the patient profiles associated with HIV-related knowledge. Methods This observational cross-sectional study included 2002 patients who attended for STI testing from August 2017 through August 2018 and completed a self-administered electronic questionnaire. Based on incorrect answers regarding HIV transmission, two outcomes were assessed: lack of knowledge and false beliefs. Factors associated with these two outcomes were explored using univariate and multivariate logistic regressions. Results Only 3.6% of patients did not know about HIV transmission through unprotected sexual intercourse and/or by sharing needles. More than one third of patients (36.4%) had at least one false belief, believing that HIV could be transmitted by sharing a drink (9.7%), kissing (17.6%) or using public toilets (27.5%). A low educational level and no previous HIV testing were associated in multivariate analyses with both lack of knowledge and false beliefs. Age and sexual orientation were also associated with false beliefs. Furthermore, 55.6% of patients did not know that post-exposure prophylaxis consists of taking emergency treatment as soon as possible after risky intercourse. Conclusions Although the main HIV transmission routes are well known, false beliefs persist and knowledge regarding PEP needs to be improved. Prevention campaigns must focus on these themes which appear as a complementary strategy to pre-exposure prophylaxis to reduce HIV infection.

Abstract Background Nonoccupational post exposure prophylaxis (nPEP) following sexual assault can prevent HIV transmission. A standardized Emergency Department (ED) protocol for evaluation, treatment, and follow up for post assault victims was implemented to improve compliance with CDC nPEP guidelines. Methods A single-center observational study of post sexual assault patients before/after implementation of an ED nPEP protocol was conducted by comparing the appropriateness of prescriptions, labs, and necessary follow up. A standardized order-set based on CDC nPEP guidelines, with involvement of an HIV pharmacist and ID clinic, was implemented during the 2018-2019 academic year. Clinical data from pre-intervention period (07/2016-06/2017) was compared to post-intervention period (07/2018-08/2019) following a 1-year washout period. Results During the study, 147 post-sexual assault patients (59 Pre, 88 Post) were included. One hundred thirty-three (90.4%) were female, 68 (46.6%) were African American and 133 (90.4%) were candidates for nPEP. Median time to presentation following assault was 12.6 hours. nPEP was offered to 40 (67.8%) and 84 (95.5%) patients (P< 0.001) and ultimately prescribed to 29 (49.2%) and 71 (80.7%) patients (P< 0.001) in pre and post periods respectively. Renal function (37.3% vs 88.6%; P< 0.001), pregnancy (39.0% vs 79.6%; P< 0.001), syphilis (3.4% vs 89.8%; P< 0.001), hepatitis B (15.3% vs 95.5%; P< 0.001) and hepatitis C (27.1% vs 94.3%) screening occurred more frequently during the post period. Labratory, nPEP Prescription and Follow up Details for Patients Prescribed nPEP Conclusion The standardization of an nPEP ED protocol for sexual assault victims resulted in increased nPEP administration, appropriateness of prescription, screening for other sexually transmitted infectious and scheduling follow up care. While guideline compliance dramatically improved, further interventions are likely warranted in this vulnerable population. Disclosures Ryan K.

Gay, bisexual, and other men who have sex with men (GBMSM) in the United States remain heavily impacted by HIV. The purpose of this study was to describe intergenerational differences in functional knowledge of HIV prevention strategies, perceived risk, recent condomless anal sex (CAS), and HIV testing behavior. Eight hundred sexually active GBMSM were recruited via Facebook from August to September 2015, and administered a Web-based survey which included 12 multiple-choice questions to elicit data regarding functional knowledge of different HIV prevention approaches (e.g., condom use, pre-exposure prophylaxis post-exposure prophylaxis, treatment as prevention, circumcision). Cumulative logit and multivariable logistic models were formulated to examine birth cohort variations across four analytic outcomes. Younger generations were significantly more knowledgeable, as were GBMSM with higher education. Non-Hispanic non-White GBMSM and those reporting a bisexual/other sexual orientation had lower functional knowledge. Younger generations were equally concerned about contracting HIV as their older counterparts. Perceived risk was significantly higher among non-Hispanic non-White and Hispanic GBMSM, but lower among those with higher education and those in a relationship. Finally, birth cohort variations with respect to engaging in CAS with ≥2 men in the past 3 months and testing for HIV in the past year were not markedly pronounced. Younger GBMSM might be more knowledgeable about HIV prevention strategies compared to their predecessors, but are equally concerned about contracting HIV. Researchers and practitioners should consider intergenerational and other demographic differences while designing multifaceted HIV prevention programs for GBMSM.

Background: Despite decreasing rates of HIV among many populations, HIV-related health disparities among gay, bisexual and other men who have sex with men persist, with disproportional percentages of new HIV diagnoses among racial and ethnic minority men. Despite increasing awareness of HIV pre-exposure prophylaxis (PrEP), PrEP use remains low. In addition to exploring individual-level factors for this slow uptake, structural drivers of PrEP use must also be identified in order to maximize the effectiveness of biomedical HIV prevention strategies. Method: Using cross-sectional data from an ongoing cohort study of young sexual minority men (N=492), we examine the extent to which structural-level barriers, including access to health care, medication logistics, counseling support, and stigma are related to PrEP use. Results: While almost all participants indicated awareness of PrEP, only 14% had ever used PrEP. PrEP use was associated with lower concerns about health care access, particularly paying for PrEP. Those with greater concerns talking with their provider about their sexual behaviors were less likely to use PrEP. Conclusion: Paying for PrEP and talking to one’s provider about sexual behaviors are concerns for young sexual minority men. In particular, stigma from healthcare providers poses a significant barrier to PrEP use in this population. Providers need not only to increase their own awareness of and advocacy for PrEP as an effective risk-management strategy for HIV prevention, but also must work to create open and non-judgmental spaces in which patients can discuss sexual behaviors without the fear of stigma.
