Perspectives on HIV Pre- and Post-Exposure Prophylaxes (PrEP and PEP) Among Female and Male Sex Workers in Mombasa, Kenya: Implications for Integrating Biomedical Prevention into Sexual Health Services

Determinants of Intention to Use HIV Pre-exposure Prophylaxis and Condom Use Among a Sample of Cisgender Female Sex Workers Working Mostly Outdoors in Madrid, Spain

There is scant knowledge regarding pre-exposure prophylaxis (PrEP) use among female sex workers (FSWs) in Europe. Spain recognized FSWs as a population at high risk of acquiring HIV and granted them subsidized access to PrEP when the medication first became nationally available in 2019. Nevertheless, FSWs represented just 0.2% of PrEP users in 2022. A total of 102 HIV-negative FSWs reached through field activities of local NGOs located in Madrid were interviewed between January and March 2022. Participants were selected through convenience sampling over a fixed recruitment period. FSWs completed a 73-item survey with questions about individual, occupational, social, and structural determinants. The objective of this study was to identify (1) the prevalence of intention to use oral PrEP and its determinants, and (2) the prevalence of inconsistent condom use, which is the risk factor that qualifies FSWs for subsidized PrEP in the national health system, and its determinants. Importantly, the study sample overrepresented street-based FSWs (71.6%). A quarter (25.5%) of the study participants used condoms inconsistently. PrEP awareness was low (9.8%), but intention to use PrEP was high (72.5%). Intention to use oral PrEP was significantly associated with feeling protected against HIV by taking PrEP and perceiving insufficient protection by condom use alone. Inconsistent condom use was significantly associated with frequent heroin/cocaine use, having clients who inject drugs, and willingness to take PrEP despite it not protecting 100% against HIV infection. FSWs, in this specific sample, are likely to benefit from targeted PrEP awareness campaigns and implementation projects that prioritize those who use drugs and are more likely to engage in condomless sex.

Barriers and facilitators to uptake and persistence on prep among key populations in Southern Province, Zambia: a thematic analysis

BACKGROUND

Especially in high HIV prevalence contexts, such as Zambia, effective biomedical prevention tools are needed for priority populations (PPs), including key populations (KPs), who are at higher risk. HIV pre-exposure prophylaxis (PrEP) has been scaled up nationally in Zambia, but little is known about barriers to PrEP use among specific PPs to date.

METHODS

To understand barriers and facilitators to PrEP use in Zambia, we conducted a qualitative case study of PrEP services to PPs including sero-discordant couples (SDCs), female sex workers (FSWs), and men who have sex with men (MSM) in Livingstone. The study conducted in 2021 included in-depth interviews (n = 43) guided by the socio-ecological model, and focus group discussions (n = 4) with clinic and community-based providers and PrEP-eligible clients including users and non-users across PP groups. We used thematic analysis to analyze data using codes derived both deductively and inductively.

RESULTS

We found multilevel barriers and facilitators to PrEP use. Cross-cutting barriers shared across PP groups included amplifying effects of PrEP being mistaken for antiretroviral drugs used to treat HIV, including anticipated stigma, and concerns about side-effects based on both misinformation and experience. In addition, stigmatized identities, particularly that of MSM, served as a barrier to PrEP use. The fear of being mislabeled as having HIV was of greatest concern for FSWs. Facilitators to PrEP use primarily included the importance of confidential, KP-sensitive services, and the role of informed, supportive family, friends, and peers. Participants across all PP groups urged expanded education efforts to increase awareness of PrEP within the general population toward mitigating concerns of being mislabeled as living with HIV.

CONCLUSION

To our knowledge, this is the first qualitative study of the PrEP cascade among multiple PPs in Zambia. This study provides important explanation for the low rates of PrEP continuation found in earlier demonstration trials among KPs in Zambia. The study also offers recommendations for programming efforts going forward such as inclusive PrEP awareness campaigns, expanded KP sensitivity training, and related efforts to thwart PrEP stigma while expanding access.

Dimensional Reduction in Barriers and Facilitators to Pre-exposure Prophylaxis (PrEP) Uptake Willingness for Full-Service Sex Workers

Full-Service Sex Workers (FSSWs) face heightened risk of acquiring HIV, yet exhibit relatively low adoption of pre-exposure prophylaxis (PrEP)-an antiviral that substantially reduces HIV acquisition risk. Little work examines barriers and facilitators to PrEP uptake willingness among FSSWs. This study aimed to identify the distinct components of barriers and facilitators to PrEP uptake willingness for FSSWs. Here, we subjected 19 PrEP barriers and facilitators identified in the literature to a principal component analysis (PCA) among a sample of 83 FSSWs. Preliminary statistics supported factorability of data. PCA revealed three distinct components of barriers and facilitators that explained 62.80% of the total variance in survey responses. We labeled these components Behavioral and Social Concerns (α = 0.93), Access and Affordability (α = 0.67), and Biologically Based Health Concerns (α = 0.79). This study shows promise for future clinical and research utility of these factors and provides a basis for future psychometric studies of barriers and facilitators to PrEP uptake willingness among FSSWs.

"Protected Means Armed": Perspectives on Pre-Exposure Prophylaxis (PrEP) Among Women Who Engage in Sex Work and Use Drugs in Kazakhstan

Pre-exposure prophylaxis (PrEP) for HIV prevention has recently become available in Kazakhstan, but women engaged in sex work who use drugs (WESW-UD) could benefit from tailored approaches to support uptake and adherence. To better understand how best to support WESW-UD at each stage of the PrEP continuum (awareness, acceptability, uptake, and adherence), we analyzed data from 30 in-depth interviews and four focus groups with 48 WESW-UD from two cities in Kazakhstan. We conducted thematic analysis to characterize perceptions, barriers, and motivators within each step of the PrEP continuum. Participants reported low awareness, but high interest in PrEP. Motivating factors included optimizing health and increased confidence. Participants expressed many preferences and concerns regarding PrEP modality and delivery. Participants also described how organizational mistrust and social support can prevent or facilitate PrEP uptake or adherence. Kazakhstan's scale-up of PrEP should consider the needs and preferences of WESW-UD to ensure equitable access.

Emergency departments as under-utilized venues to provide HIV prevention services to female sex workers in Nairobi, Kenya

BACKGROUND

Female sex workers (FSW) in sub-Saharan Africa are disproportionately affected by HIV and remain a key target population for efforts to reduce transmission. While HIV prevention tools such as PEP and PrEP are available through outpatient FSW clinics, these services are underused. Emergency medicine is a rapidly expanding field in Kenya and may provide a novel venue for initiating or optimizing HIV prevention services. This study examined the characteristics of FSW from Nairobi, Kenya, who had utilized an emergency department (ED) during the past year to broaden our understanding of the patient factors related to usage.

METHODS

An anonymous questionnaire was administered to a convenience sample of 220 Nairobi FSW attending dedicated clinics from June to July 2019. The participants were categorized into those who attended an ED over the past year (acute care users) and clinic-only users (control). A modified version of the WHO Violence Against Women Instrument assessed gender-based violence. Multivariable negative binomial logistic regressions evaluated predictors of health care use among these populations.

RESULTS

Of the total 220 women (median [IQR] age 32 [27-39]), 101 and 116 were acute care and control populations, respectively. Acute care users had 12.7 ± 8.5 healthcare visits over a 12-month period, and the control population had 9.1 ± 7.0 (p < 0.05). ED attendance did not improve the PrEP usage, with 48.5%, and 51% of acute care and clinic users indicated appropriate PrEP use. Patient factors that correlated with health care utilization among acute care users included client sexual violence (OR 2.2 [1.64-2.94], p < 0.01), PrEP use (OR 1.54 (1.25-1.91), < 0.01), and client HIV status (OR 1.35 (1.02-1.69), p < 0.01).

CONCLUSIONS

Many FSW at high risk for HIV were not accessing HIV prevention tools despite attending a dedicated FSW clinic offering such services. FSW who had attended an ED over the past year had a higher prevalence of HIV risk factors, demonstrating that emergency departments may be important acute intervention venues to prevent HIV transmission in this population. These results can guide policy design, health care provider training, and facility preparedness to support strategies aimed at improving HIV prevention strategies for FSW in Kenyan ED's.

Condom Use Among Male Sex Workers With Their Male Clients in Mombasa, Kenya: Results of a Sub-analysis of a Pilot, Multilevel, Structural, HIV Risk-Reduction Intervention

ABSTRACT

Despite the advent of preexposure prophylaxis, consistent condom use continues to be recommended because preexposure prophylaxis does not prevent sexually transmitted infections. This is important for high-risk populations (e.g., male sex workers; MSW) in low-resource, high-HIV/sexually transmitted infection prevalence settings, such as the Mombasa region in Kenya. This study aimed to examine the relationship between MSW's condom use, and their knowledge, beliefs, and attitudes about condoms. MSW (N = 158) completed surveys on their sexual behaviors/practices/attitudes. We used multiple regressions to identify associations between condom use, HIV knowledge/attitudes, and self-efficacy. Three quarters of participants reported always using condoms in the past week, and 64.3% reported always using condoms in the past month with male clients. Mean scores for knowledge and attitudes/self-efficacy toward condoms/safer sex were positively associated with condom use. Interventions to build self-efficacy, such as condom negotiation, and/or bringing up condom use with clients may be useful for Kenyan MSW.

Oral Pre-Exposure Prophylaxis (PrEP) Awareness and Acceptability Among Persons who Inject Drugs (PWID) in Kenya: A Qualitative Investigation

Background

People who inject drugs (PWID) are disproportionately affected by HIV despite the availability of multiple efficacious biomedical prevention interventions including oral pre-exposure prophylaxis (PrEP). Little is known about the knowledge, acceptability, and uptake of oral PrEP among this population in Kenya. To inform the development of oral PrEP uptake optimization interventions for PWID in Kenya, we conducted a qualitative assessment to establish oral PrEP awareness and willingness to take PrEP by this group in Nairobi City.

Methodology

Guided by the Capability, Opportunity, Motivation, and Behaviour (COM-B) model of health behavior change, we conducted 8 focus group discussions (FGDs) among randomly constituted samples of PWID in four harm reduction drop-in centers (DICs) in Nairobi in January 2022. The domains explored were: perceived risks (behaviour), oral PrEP awareness and knowledge (capability), motivation to use oral PrEP (behaviour), and perceptions on community uptake (motivation and opportunity). Completed FGD transcripts were uploaded to Atlas.ti version 9 and thematic analysis was conducted through an iterative process of review and discussion by two coders.

Findings

There was a low level of oral PrEP awareness with only 4 of the 46 PWID having heard of PrEP; only 3 out of 46 participants had ever used oral PrEP and 2 out of 3 were no longer using it, indicating a low capacity to make decisions on oral PrEP. Most study participants were aware of the risk posed by unsafe drug injection and expressed willingness to take oral PrEP. Nearly all participants demonstrated low understanding of the role oral PrEP plays in complementing condoms in HIV prevention, presenting an opportunity for awareness creation. While the PWID were eager to learn more about oral PrEP, they favored DICs as places where they would like to obtain information and oral PrEP if they chose to use it, identifying an opportunity for oral PrEP programming interventions.

Conclusion

Creation of oral PrEP awareness among PWID in Kenya is likely to improve uptake since the PWID are receptive. Oral PrEP should be offered as part of combination prevention approaches, and effective messaging through DICs, integrated outreaches, and social networks are recommended to mitigate displacement of other prevention and harm reduction practices by this population.

Pre-exposure prophylaxis use among female sex workers in Gulu city, Uganda: a community-based cross-sectional study

Background

Pre-exposure prophylaxis (PrEP) is an important intervention for reducing the risk of HIV transmission among high-risk populations such as female sex workers in Africa, where HIV prevalence remains high. We aimed to assess the use of PrEP among female sex workers in Gulu, Uganda.

Methods

In this community-based cross-sectional study, we included HIV-negative female sex workers purposely selected from hotspots within Gulu city, Uganda between February and March 2023. A semi-structured questionnaire was administered to collect data on sociodemographic characteristics, reproductive data, sexual practices, and self-reported PrEP use in the past 3 months. Symptoms of depression were screened using Patient Health Questionnaire-2 tool. Predictors of PrEP use was determined using modified Poisson regression analysis model. p < 0.05 was considered statistically significant.

Results

We enrolled 273 female sex workers with a median age of 27 (interquartile range: 24-32) years. Overall, 181 (66.3%) participants used PrEP. PrEP use was associated with; regular source of income beside sex work [adjusted prevalence ratio (aPR): 3.7, 95% confidence interval (CI): 2.11-6.35, p < 0.001], being in a polygamous marriage (aPR: 6.9, 95% CI: 1.32-35.77, p = 0.022), practicing sex work in both rural and urban areas (aPR: 2.5, 95% CI: 1.49-4.35, p < 0.001), having symptoms of depression (aPR: 3.3, 95% CI: 1.43-7.74, p = 0.005), and use of postexposure prophylaxis (PEP) in the past 12 months (aPR: 0.31, 95% CI: 0.17-0.59, p < 0.001).

Conclusion

Almost two in three of the female sex workers in Gulu city were currently using PrEP. Previous use of PEP was associated with lower use of PrEP. These findings suggest the need for targeted interventions to increase PrEP uptake and decrease HIV acquisition in this high-risk population among female sex workers, especially those with low income and limited access to healthcare.

"I decided in my heart I have to complete the sessions": A qualitative study on the acceptability of an evidence-based HIV risk reduction intervention among women engaged in sex work in Uganda

BACKGROUND

The HIV burden remains a critical public health concern and women engaged in sex work [WESW] are at significantly higher risk compared to the general adult population. Similar to other sub-Saharan African countries, Uganda reports high rates of HIV prevalence among WESW. Yet, they have not been targeted by theory-informed HIV prevention intervention approaches.

METHODS

We conducted semi-structured in-depth interviews with 20 WESW upon intervention completion to explore their experiences with an evidence-based HIV risk reduction intervention that was implemented as part of a combination intervention tested in a clinical trial in Uganda (2018-2023. Specifically, we explored their initial motivations and concerns for participating in the intervention, barriers and facilitators to attendance, and their feedback on specific intervention characteristics.

RESULTS

The main expectations revolved around access to health-related information, including information on STIs, HIV, and PrEP as well as on how one can protect themselves while engaging in sex work. Initial concerns were around potential breach of confidentiality and fear of arrest. The main facilitators for session attendance were the motivation to learn health-related information, the attitude of facilitators, and the incentives received for participation, whereas main challenges were related to family commitments and work schedules. WESW appreciated the group format of the intervention and found the location and times of the intervention delivery acceptable.

DISCUSSION AND CONCLUSIONS

Overall, our findings suggest that the HIV risk reduction intervention was appropriate and acceptable to WESW. Yet, WESW experience unique concerns and barriers that need to be accounted for when designing interventions targeting this population, especially in resource-limited settings where sex work is illegal and highly stigmatized.

End-user research in support of long-acting systemic antiretroviral delivery systems: insights from qualitative research with providers and target users in South Africa

BACKGROUND

While oral pre-exposure prophylaxis (PrEP) has been shown to reduce the risk of HIV, challenges such as adhering to a daily-dosing regimen and persistence have emerged as barriers for at-risks populations in South Africa. This qualitative research sought to investigate perceptions of and preferences for a long-acting, biodegradable implantable PrEP product designed to address these barriers.

METHODS

To identify and understand motivators, barriers, and preferences for the PrEP implant, we conducted qualitative in-depth interviews (IDIs) among health care providers (HCPs) and target end-users (young women, adolescent girls, and female sex workers) in urban and rural/peri-urban regions of Gauteng Province, South Africa. The IDIs focused on defining values, beliefs, habits, lifestyles, influencers, and information channels for potential PrEP implant end-users.

RESULTS

We conducted 36 IDIs across health care providers and target end-user respondent segments. Respondents had generally positive reactions to the PrEP implant. Most end-users felt that some undesirable aspects of the implant (e.g., side effects, pain during insertion, potential scarring, and inability to remove implant) would be offset by having a highly effective, and long-lasting HIV prevention product. Although some HCPs believed the implantable PrEP would lead to increases in promiscuity and risky sexual behavior, most HCPs saw value in the PrEP implant's long duration of protection, its biodegradability, and the likelihood of higher adherence relative to oral PrEP.

CONCLUSIONS

This study is a first step toward further research needed to demonstrate the demand for a biodegradable, long-acting implantable PrEP and suggests such a product would be accepted by end-users and HCPs in South Africa. This study indicates the need to develop more convenient, discreet, long-acting, and highly effective biomedical HIV prevention options for at-risk populations.

A retreat from human rights? A reflection on sex work's place in contemporary HIV prevention

In 2012, the World Health Organization guidelines for HIV prevention recommended the decriminalisation of sex work as their number one good practice. Although human rights language played a key role in the international scientific and activist endorsement of the WHO policies, since then there have been few initiatives in terms of advancing the kinds of structural and political changes endorsed. In this Commentary, we reflect on sex work's place in the broader field of the biomedicalization of responses to HIV. The analysis is based on literature reviews and our research trajectories, including preliminary results from a qualitative study on the implementation of PrEP in Rio de Janeiro, Brazil. We argue that sex workers occupy an ambiguous and less visible role in current AIDS policies, and that such policies are increasingly characterised by their prioritisation of biomedical approaches over structural factors. These shifts should be understood as part of a broader, global hegemony of clinical responses to HIV prevention and the continuation of a neoliberal discourse around human rights, without adequate investment in the material conditions necessary to guarantee these rights.

The impact of mucormycosis (black fungus) on SARS-CoV-2-infected patients: at a glance

The emergence of various diseases during the COVID-19 pandemic made health workers more attentive, and one of the new pathogens is the black fungus (mucormycosis). As a result, millions of lives have already been lost. As a result of the mutation, the virus is constantly changing its traits, including the rate of disease transmission, virulence, pathogenesis, and clinical signs. A recent analysis revealed that some COVID-19 patients were also coinfected with a fungal disease called mucormycosis (black fungus). India has already categorized the COVID-19 patient black fungus outbreak as an epidemic. Only a few reports are observed in other countries. The immune system is weakened by COVID-19 medication, rendering it more prone to illnesses like black fungus (mucormycosis). COVID-19, which is caused by a B.1.617 strain of the SARS-CoV-2 virus, has been circulating in India since April 2021. Mucormycosis is a rare fungal infection induced by exposure to a fungus called mucormycete. The most typically implicated genera are Mucor rhyzuprhizopusdia and Cunninghamella. Mucormycosis is also known as zygomycosis. The main causes of infection are soil, dumping sites, ancient building walls, and other sources of infection (reservoir words "mucormycosis" and "zygomycosis" are occasionally interchanged). Zygomycota, on the other hand, has been identified as polyphyletic and is not currently included in fungal classification systems; also, zygomycosis includes Entomophthorales, but mucormycosis does not. This current review will be focused on the etiology and virulence factors of COVID-19/mucormycosis coinfections in COVID-19-associated mucormycosis patients, as well as their prevalence, diagnosis, and treatment.

Bictegravir nanomicelles and anionic pullulan loaded vaginal film: Dual mechanistic pre-exposure prophylaxis (PrEP) for HIV

Locally delivered pre-exposure prophylaxis (PrEP) has proven to be a promising strategy to combat Human immunodeficiency virus (HIV) transmission but several findings encountered toxicities or proved to be marginally effective in clinical settings. Therefore, innovative, multifunctional, and safer alternatives are being progressively investigated. Herein, we explored negatively charged carbohydrate, anionic pullulan (AP) as a rapidly soluble film-former and novel anti-HIV agent. Additionally, Bictegravir (BCT), an HIV integrase inhibitor was co-delivered in the form of nanomicelles for sustained antiviral activity. BCT-loaded PLGA-PEG polymeric nanomicelles (BN) were incorporated into PVA/pullulan-based film matrix comprising of 2 % w/v AP (BN-AP film). In cell-based assays, biocompatibility and TEER values for BN-AP films were similar to control while the commercial vaginal contraceptive film (VCF®) showed severe cytotoxicity and drastically reduced the tight junction integrity. Rapid disintegration of BN-AP film with >85 % drug release was observed in simulated vaginal and seminal fluid. Most importantly, AP and BN-AP film significantly inhibited HIV-1 replication with IC₅₀ at as low as 91 μg/mL and 0.708 nM, respectively. Therefore, this study entails successful development of BN-AP film that functioned as an effective, biocompatible dual-acting PrEP formulation.

Sexual Violence and Low Rates of HIV Post-exposure Prophylaxis Access Among Female Sex Workers in Brazil

Female sex workers (FSW) are disproportionately affected by sexual violence (SV) and HIV. Social and structural barriers limit their access to post-exposure prophylaxis (PEP). Respondent-driven sampling survey in 12 Brazilian cities among 4188 FSW aimed to estimate the rates of SV and factors associated with access to PEP use among FSW who experienced SV. The prevalence of SV was 26.3% (1199). Of the 1199, 7.5% sought out healthcare and used PEP, 19% sought out healthcare, but did not use PEP, and 73.5% did not seek out healthcare after SV. Factors associated with PEP use included PEP awareness, participation in HIV/STI prevention workshops, and disclosure of FSW status in healthcare services. Although Brazil has a PEP program free of charge, it is not readily accessible, even for FSW who seek out healthcare. The development of effective strategies to link FSW to HIV preventive services is urgently needed.

Low awareness of oral and injectable PrEP among high-risk adolescent girls and young women in Kampala, Uganda

BACKGROUND

Adolescent girls and young women (AGYW) account for a disproportionate number of new HIV infections worldwide. HIV prevalence among young sex workers in Uganda is 22.5%. Although pre-exposure prophylaxis (PrEP) is a highly effective biomedical HIV prevention method, awareness of PrEP among AGYW in Uganda has not been studied systematically. We aimed to assess awareness of PrEP and factors associated with awareness of PrEP among AGYW who frequently reported paid sex.

METHODS

We conducted a cross-sectional study among 14-24-year old AGYW at high risk of HIV infection in Kampala, Uganda from January to October 2019. Participants were screened for PrEP eligibility using a national screening tool of whom 82.3% were eligible. Data on socio-demographics, behavioral and sexual risks were collected by interview. Awareness of oral or injectable PrEP, the latter of which is currently in late-stage trials, was defined as whether an individual had heard about PrEP as an HIV prevention method. Multivariable robust poisson regression model was used to assess factors associated with oral PrEP awareness.

RESULTS

We enrolled 285 participants of whom 39.3% were under 20 years old, 54.7% had completed secondary education, 68.8% had multiple sex partners in the past 3 months, 8.8% were screened as high risk drinkers'/ alcohol dependent (AUDIT tool) and 21.0% reported sex work as main occupation. Only 23.2% were aware of oral PrEP and 3.9% had heard about injectable PrEP. The prevalence of oral PrEP awareness was significantly higher among volunteers screened as alcohol dependents (aPR 1.89, 95% CI 1.08-3.29) and those with multiple sexual partners (aPR 1.84, 95% CI 1.01-3.35), but was lower among those who reported consistent condom use with recent sexual partners (aPR 0.58, 95% CI 0.37-0.91).

CONCLUSIONS

Majority of AGYW were not aware of any kind of PrEP. Those with higher risk behavior, i.e. alcohol dependents or multiple sexual partners, were more aware of oral PrEP. Interventions to increase awareness among female youth are needed. Improving PrEP awareness is critical to increasing PrEP uptake among high-risk AGYW in Uganda.

"I expected little, although I learned a lot": perceived benefits of participating in HIV risk reduction sessions among women engaged in sex work in Uganda

BACKGROUND

The global HIV burden remains a public health concern. Women engaged in sex work (WESW) are at higher risk of acquiring HIV compared to the general adult population. Uganda reports high rates of HIV prevalence among WESW. While WESW in Uganda have long been the subject of surveillance studies, they have not been targeted by theory-informed HIV prevention intervention approaches. In this study, we explored the perceived benefits of an evidence-based HIV risk reduction intervention that was implemented as part of a combination intervention tested in a clinical trial in Uganda.

METHODS

As part of a larger randomized clinical trial, we conducted semi-structured in-depth interviews with 20 WESW selected using a stratified purposive sampling. All interviews were conducted in Luganda, language spoken in the study area, and audio-recorded. They were transcribed verbatim and translated to English. Thematic analysis was used to analyze the data.

RESULTS

WESW's narratives focused on: (1) condom use; (2) alcohol/drug consumption; (3) PrEP use; (4) "handling" customers; and (5) "massaging" customers. WESW agreed that male condom was one of the important learning points for them and planned to continue using them while female condoms were received with mixed reactions. Many women appreciated receiving information about the risks of consuming alcohol and drugs, and discussed how they reduced/ eliminated their consumption. PrEP information was appreciated though identified by fewer WESW. Handling a client was discussed as a helpful strategy for safer sex through improved ability to convince customers to use condoms or avoiding sex. Massaging was also beneficial to avoid penetrative sex, but similar to female condom, massaging also yielded mixed perceptions.

CONCLUSION

WESW found the intervention beneficial and described ways in which it improved their ability to engage in safer sex and stay healthy. The fact that WESW identified other strategies beyond condom use as helpful underlines the importance of adopting a comprehensive approach to behavioral interventions targeting HIV prevention even when combined with other interventions. Additionally, WESW's narratives suggest that incorporating the tenets of social cognitive theory and harm reduction approaches in HIV prevention among this population can result in risk behavior change.

Effect of HIV Self-Testing on PrEP Adherence Among Gender-Diverse Sex Workers in Uganda: A Randomized Trial

BACKGROUND

HIV self-testing (HIVST) and pre-exposure prophylaxis (PrEP) are complementary tools that could empower sex workers to control their HIV protection, but few studies have jointly evaluated PrEP and HIVST in any setting.

METHODS

The Empower Study was an open-label randomized trial in Uganda. Sex workers were offered F/tenofovir disoproxil fumarate and randomized 1:1 to monthly HIVST and quarterly in-clinic testing (intervention) or quarterly in-clinic HIV testing alone (standard of care) and followed up for 12 months. PrEP adherence was measured using electronic adherence monitoring and tenofovir diphosphate (TFV-DP) levels in dried blood spots. Adherence outcomes and sexual behaviors were compared by arm using generalized estimating equation models.

RESULTS

We enrolled 110 sex workers: 84 cisgender women, 14 transgender women, 10 men who have sex with men, and 2 transgender men. The median age was 23 years. The 12-month retention was 75%. Nearly all (99.4%) used ≥1 HIVST kit. The proportion with TFV-DP levels ≥700 fmol/punch in the HIVST and standard of care arms at the 3-, 6-, 9-, and 12-month visits was 2.4%, 2.3%, 0%, and 0% and 7.9%, 0%, 0%, and 0%, respectively, with no differences by randomization arm (P > 0.2). Self-reported condomless sex acts with paying partners was similar by arm [adjusted incidence rate ratio 0.70; 95% confidence interval (CI): 0.42 to 1.17; P = 0.18]. One seroconversion occurred (HIV incidence, 0.9/100 person-years); TFV-DP was not detected at any visit.

CONCLUSIONS

A gender-diverse sample of sex workers in Uganda used HIVST but not daily oral PrEP for HIV protection. Alternate approaches to promote PrEP use, including long-acting formulations, should be considered in this population.

Willingness to take and ever use of pre-exposure prophylaxis among female sex workers in Ghana

Pre-exposure prophylaxis (PrEP) is a drug taken by people who are human immunodeficiency virus (HIV) negative and at increased risk of acquiring HIV. It's an effective intervention for HIV prevention. This study seeks to report on the prevalence and determinants of willingness to take and ever use of PrEP among female sex workers (FSW) in Ghana.The data analyzed was obtained from the Integrated Bio-behavioral Surveillance Survey conducted across the 16 regions of Ghana in 2020. Analysis was only performed on FSW who were tested negative to HIV and were sexually active. All included variables were described using medians, percentages, and graphs. Bayesian adjusted odds ratios and 95% credible intervals were estimated using a Bayesian generalized linear model via the binomial family of distributions under the logit link function.Of the 5107 FSW with complete data on willingness to use PrEP, 2737 (53.59%) reported their willingness to take PrEP. Out of the 998 respondents who have ever heard of PrEP only 64 (6.39%) have ever used PrEP. The median age of the respondents was 25 years. People with no comprehensive knowledge of HIV and acquired immunodeficiency syndrome as well as those who entered into the FSW business at age less than 25 years; 946 (34.56%) and 2181 (79.65%) respectively were more willing to take PrEP. FSW from 6 out of the 16 regions of Ghana have never used PrEP. A statistically significant difference between those who entered the sex work at age less than 25 years and those within 25 to 34 years was observed. About 23% of FSWs who had been screened for Sexually Transmitted Infections were more likely to take PrEP.Respondents with lesser age and no comprehensive knowledge of HIV were more willing to take PrEP. The willingness to accept PrEP among FSWs in Ghana is modest. However, utilization is low. Advocacy or intervention programs are required to improve uptake of PrEP.

PrEP acceptability and initiation among women engaged in sex work in Uganda: Implications for HIV prevention

BACKGROUND

Women engaged in sex work (WESW) are disproportionately affected by HIV. In Uganda, HIV prevalence among WESW is estimated at 37%, accounting for 18% of all new infections in the country. WESW experience poverty, gender-based violence, and other issues that reduce their power and limit their ability to negotiate condom use. Female-controlled strategies, including pre-exposure prophylaxis (PrEP), may afford women more transmission protection, but barriers to access and use persist. This cross-sectional study examined baseline PrEP acceptability and initiation among WESW recently enrolled in a randomized clinical trial in Uganda to test the impact of a combination HIV risk reduction and economic empowerment intervention on sexual risk outcomes (clinicaltrials.gov, NCT03583541).

METHODS

A total of 542 WESW from 19 high HIV-prevalent geographical areas were enrolled in the Kyaterekera study between June 2019 and March 2020. Women were eligible for the study if they: (1) were age 18 or over; (2) reported engagement in transactional sex (a sex act in exchange for pay) in the past 30 days; and (3) reported engagement in one or more episodes of unprotected sex in the past 30 days. Women completed a baseline assessment, were tested for HIV and other sexually transmitted infections (STIs) at enrollment, and were connected with antiretroviral therapy (ART), STI treatment, or PrEP, based on need and interest. Descriptive statistics examined baseline data on PrEP acceptability and initiation. Independent variables (i.e. years in sex work, recent sexual coercion, perceived HIV and sex work stigmas, harmful alcohol use, barriers to medical care, and social support) were derived from the empirical literature and women's self-report. Bivariate analysis was performed to test associations between main effects of these variables. Using binomial logistic regression, predictive models were evaluated for two distinct outcomes-PrEP acceptability and PrEP initiation/uptake.

FINDINGS

At baseline, 59% of women (n = 322) tested HIV negative. Among WESW testing negative, 11% (n = 36) were already PrEP enrolled. Most women reported willingness to use PrEP (n = 317; 91%). Slightly over half of WESW not already on PrEP agreed to initiate PrEP (n = 158; 55%). Logistic regression models demonstrate that acceptability of or willingness to use PrEP was significantly associated with fewer years engaged in sex work (AOR= ·18, 95% CI 0·05-·66, p<·01) and greater perceived social support from family (AOR= 1·39, 95% CI 1·03 -1.88, p<·05). PrEP initiation was negatively associated with greater perceived social support from friends (AOR=·81, 95% CI ·68-0·97, p<·05) and positively associated with higher perceived stigma due to sex work among family members (AOR=2·20, 95% CI 1·15-4·22, p<·05).

INTERPRETATION

Despite endorsing PrEP use, many WESW remain reluctant to use it. This gap in prevention practice highlights the heart of a failing PrEP prevention cascade. Findings point to the important role family and friend support may play in destigmatizing sex work and PrEP use for women. Social and structural-level efforts are needed to improve educational messaging and to integrate positive messaging into health promotion campaigns for women and their families, while also working toward decriminalizing sex work.

Gender-Inclusive and Gender-Specific Approaches in Trans Health Research

The recent proliferation of trans health literature for the past 20 years has prompted a need to examine two contested approaches used in designing study protocols and analyses in trans health research, as either specific to only one gender group (gender-specific approach) or across gender groups (i.e., gender-inclusive approach). In this critique, we aim to explicate and provide guidance for when the application of each approach is methodologically appropriate.

Knowledge and attitudes about HIV pre-exposure prophylaxis: Evidence from in-depth interviews and focus group discussions with policy makers, healthcare providers, and end-users in Lesotho

Studies on knowledge and attitudes about HIV pre-exposure prophylaxis (PrEP) have mostly focused on key populations in North America and Europe. To inform Lesotho's national rollout of PrEP to the general population, this study aimed to characterize knowledge and attitudes about PrEP among policy makers, implementing partners, healthcare providers, and PrEP end-users in Lesotho. Respondents were purposively selected to participate based on personal experience in the development and implementation of Lesotho's PrEP program, or the personal use of PrEP. We conducted 106 in-depth interviews with policy makers (n = 5), implementing partners (n = 4), and end-users (current PrEP users = 55; former PrEP users = 36; and PrEP "decliners" = 6). In addition, we held 11 focus group discussions (FGDs) with a total of 105 healthcare providers. Interview and FGD transcripts were analyzed following the tenets of Grounded Theory. Respondents expressed positive attitudes toward PrEP, owing to experienced and perceived personal, familial, and societal benefits. PrEP was viewed as i) an opportunity for serodiscordant couples to remain together, ii) a means of conceiving children with minimized risk of HIV infection, iii) providing a sense of agency and control, and iv) an avenue for addressing the HIV epidemic in Lesotho. Respondents demonstrated understanding of PrEP's intended use, eligibility requirements, and modality of use. However, respondents also reported that several important misconceptions of PrEP were common among adults in Lesotho, including a belief that PrEP protects against sexually transmitted infections other than HIV, promotes promiscuity, prevents pregnancy, causes seroconversion, and provides lifelong protection from taking the pill just once. In addition to building on the perceived advantages of PrEP to shape a positive message, Lesotho's national rollout of PrEP will likely benefit from a communication strategy that specifically addresses the common misconceptions of PrEP identified in this study.

Impact of pre-exposure and post-exposure prophylaxes prevention programme on HIV burden and services in a low-resource setting: a simulation modelling approach

Introduction

sub-Saharan African countries contribute substantially to the global HIV disease burden. Despite this burden, and the promises that prevention could deliver, the implementation and uptake of HIV prevention programmes are still low. The study used the decision support system model to explore the potential impacts of prevention implementation on HIV burden (incidence) and service delivery.

Methods

an operational research technique known as discrete event simulation model was used to capture an individual patient´s pathways through the HIV care process from diagnosis to treatment and monitoring. The regular monitoring, over a 5-year period, including all the activities and resources utilized at each stage of the pathway were analysed, and the impact of increasing prevention measures for an HIV treatment service in a treatment centre in Nigeria was tested using the simulation model.

Results

forty-three patients currently access the Pre-Exposure Prophylaxis (PrEP) and Post Exposure Prophylaxis (PEP) annually, with a 20% and 80% split in the number of patients offered PrEP and PEP, respectively. Scenarios-based on increasing the number of people offered PrEP and PEP from 43 to 250 with a 50/50 split were tested. The outputs revealed improved preventive care by averting new HIV cases, reduction in service demand and utilization, but an increase in the required human resource as well as financial burden. In the next 5 years, the cumulative averted HIV cases are expected to increase from 2 and 5 people (baseline) to 24 and 20 people for PrEP and PEP, respectively. The potentially averted 2 cases per infected persons based on the basic reproductive number of HIV.

Conclusion

the effective implementation of PrEP/PEP programme offers an additional safety measure to prevent HIV transmission in at-risk individuals and possibility of ending HIV epidemic.

Barriers and facilitators to pre-exposure prophylaxis uptake among male sex workers in Mexico: an application of the RE-AIM framework

Background

The ImPrEP México demonstration project is the first to distribute free HIV pre-exposure prophylaxis (PrEP) to men who have sex with men (MSM) and transgender women living in Mexico. In Mexico City, MSM who are also male sex workers (MSWs) face a disproportionately high risk of HIV infection. PrEP is highly effective for HIV prevention, yet “real-life” implementation among MSWs is a challenge due to the unique adherence barriers faced by this population.

Methods

This study uses the RE-AIM implementation science framework to characterize the unique barriers to and facilitators of PrEP uptake among MSWs in Mexico City. We conducted 9 in-depth key informant interviews and 2 focus group discussions with MSWs across 5 clinic and community sites. Qualitative data were analyzed using inductive, open coding approaches from grounded theory. We supplemented findings from the primary qualitative analysis with quantitative indicators derived from ImPrEP program records to describe the current Reach of the ImPrEP program among MSWs in Mexico City and the potential for wider PrEP Adoption among other high-risk populations in Mexico.

Results

The Reach of the ImPrEP program was 10% of known HIV-negative MSWs in Mexico City. Program Reach was lowest among MSWs who were street-based sex workers, of lower socioeconomic status, migrants from other states and self-identified as heterosexual. Barriers to program Reach included limited PrEP knowledge, HIV-related stigma, and structural barriers; facilitators included in-person program recruitment, patient-centered care, and spread of information through word of mouth among MSWs. Two out of the four eligible institutions had adopted the ImPrEP protocol. Barriers to wider program Adoption included HIV- and sexual identity– related stigma, protocol limitations, and lack of a national policy for PrEP distribution; facilitators of Adoption included existing healthcare infrastructure, sensitized providers, and community support from non-governmental organizations.

Conclusions

Increasing the ImPrEP program’s Reach among MSWs will depend on improving PrEP education and addressing HIV-related stigma and access barriers. Future Adoption of the ImPrEP program should build on existing clinical infrastructure and community support. Creation of a national policy for PrEP distribution may improve the Reach and Adoption of PrEP among highest-risk populations in Mexico.

Qualitative Assessment of Barriers and Facilitators of PrEP Use Before and After Rollout of a PrEP Program for Priority Populations in South-central Uganda

Uganda piloted HIV pre-exposure prophylaxis (PrEP) for priority populations (sex workers, fishermen, truck drivers, discordant couples) in 2017. To assess facilitators and barriers to PrEP uptake and adherence, we explored perceptions of PrEP before and experiences after rollout among community members and providers in south-central Uganda. We conducted 75 in-depth interviews and 12 focus group discussions. We analyzed transcripts using a team-based thematic framework approach. Partners, family, peers, and experienced PrEP users provided adherence support. Occupational factors hindered adherence for sex workers and fishermen, particularly related to mobility. Pre-rollout concerns about unskilled/untrained volunteers distributing PrEP and price-gouging were mitigated. After rollout, awareness of high community HIV risk and trust in PrEP effectiveness facilitated uptake. PrEP stigma and unexpected migration persisted as barriers. Community-initiated, tailored communication with successful PrEP users may optimize future engagement by addressing fears and rumors, while flexible delivery and refill models may facilitate PrEP continuation and adherence.

Derivation of an HIV Risk Score for African Women Who Engage in Sex Work

No tool exists to stratify HIV risk in contemporary African female sex worker (FSW) populations. Data from a cohort of HIV-negative FSWs in Mombasa, Kenya from 2010 to 2017 were used to conduct a survival analysis assessing predictors of HIV infection. Stepwise regression was used to construct a multivariable model that formed the basis for the score. Seventeen HIV infections occurred over 1247 person-years of follow-up contributed by 670 women. Using depot medroxyprogesterone acetate (DMPA), having a curable sexually transmitted infection (STI), and being married contributed points to the score. HIV incidence was 0.85/100 person-years in a lower-risk group and 3.10/100 person-years in a higher-risk group. In a cohort with overall HIV incidence < 1.50/100 person-years, this risk score identified a subgroup of FSWs with HIV incidence > 3.00/100 person-years, which is the threshold used by the World Health Organization for initiating pre-exposure prophylaxis (PrEP). If validated in an external population, this tool could be useful for targeted PrEP promotion among higher-risk FSWs.

Male Sex Workers Selling Physical Sex during the COVID-19 Pandemic in Portugal: Motives, Safer Sex Practices, and Social Vulnerabilities

The purpose of this research was to assess the motives, safer sex practices, and vulnerabilities of male sex workers who sold physical sex during the COVID-19 pandemic. This study used a mixed strategy, utilizing purposive sampling techniques to conduct 13 online surveys with male sex workers working in Portugal during the COVID-19 pandemic. Participants were aged between 23 and 47 years old and mostly provided their services to other men. Additionally, half of the participants were immigrants. Participants mentioned paying for essential expenses (rent, food, phone, etc.), having money for day-to-day expenses, wanting to, and enjoying it, as their main motives for engaging in sex work. Regarding sexual practices, 3 to 11 participants did not always or did not consistently use condoms during penetrative sex with their clients. Thematic analysis was used to identify the following repeated patterns of meaning regarding COVID-19-related vulnerabilities, encompassing a loss of clients and income, increased work availability, price reductions and negotiation difficulties, emotional functioning, health care access, safer sex negotiations, age, and immigration status. The findings serve as a basis for recommendations regarding social policies aimed at male sex workers who sell physical sex in Portugal.

Uptake and outcomes of a novel community-based HIV post-exposure prophylaxis (PEP) programme in rural Kenya and Uganda

INTRODUCTION

Antiretroviral-based HIV prevention, including pre-exposure prophylaxis (PrEP), is expanding in generalized epidemic settings, but additional prevention options are needed for individuals with periodic, high-risk sexual exposures. Non-occupational post-exposure prophylaxis (PEP) is recommended in global guidelines. However, in Africa, awareness of and access to PEP for sexual exposures are limited. We assessed feasibility, acceptability, uptake and adherence in a pilot study of a patient-centred PEP programme with options for facility- or community-based service delivery.

METHODS

After population-level HIV testing with universal access to PrEP for persons at elevated HIV risk (SEARCH Trial:NCT01864603), we conducted a pilot PEP study in five rural communities in Kenya and Uganda between December 2018 and May 2019. We assessed barriers to PEP in the population and implemented an intervention to address these barriers, building on existing in-country PEP protocols. We used community leaders for sensitization. Test kits and medications were acquired through the Ministry of Health supply chain and healthcare providers based at the Ministry of Health clinics were trained on PEP delivery. Additional intervention components were (a)PEP availability seven days/week, (b)PEP hotline staffed by providers and (c)option for out-of-facility medication delivery. We assessed implementation using the Proctor framework and measured seroconversions via repeat HIV testing. Successful "PEP completion" was defined as self-reported adherence over four weeks of therapy with post-PEP HIV testing.

RESULTS

Community leaders were able to sensitize and mobilize for PEP. The Ministry of Health supplied test kits and PEP medications; after training, healthcare providers delivered the 28-day regimen with high completion rates. Among 124 persons who sought PEP, 66% were female, 24% were ≤25 years and 42% were fisherfolk. Of these, 20% reported exposure with a serodifferent partner, 72% with a new or existing relationship and 7% from transactional sex. 12% of all visits were conducted at out-of-facility community-based sites; 35% of participants had ≥1 out-of-facility visit. No serious adverse events were reported. Overall, 85% met the definition of PEP completion. There were no HIV seroconversions.

CONCLUSIONS

Among individuals with elevated-risk exposures in rural East African communities, patient-centred PEP was feasible, acceptable and provides a promising addition to the current prevention toolkit.

Awareness and uptake of pre-exposure prophylaxis for HIV among low-income, HIV-negative heterosexuals in San Francisco

We examined pre-exposure prophylaxis (PrEP) awareness and uptake among low-income heterosexual men and women in San Francisco in 2019. Of 294 HIV-negative survey participants, 42.5% were aware of PrEP. Few women (12.5%) and men (8.9%) had discussed PrEP with a healthcare provider; 3.8% of women and 0% of men had used PrEP in the last year. White participants (adjusted odds ratio (aOR) 5.39, 95% CI 1.02, 28.56), women (aOR 2.19, 95% CI 1.30, 3.70), and age 60 years or above (aOR 4.00, 95% CI 1.12, 14.34) had greater odds of being aware of PrEP. Testing for HIV or sexually transmitted infection in the past year was marginally associated with a greater PrEP awareness. Our findings reveal gaps in PrEP implementation associated with social disparities among low-income heterosexuals. Testing services and targeted promotional and educational materials are needed lest high-risk, low-income populations are left behind in San Francisco's aggressive "Getting to Zero" efforts.

Pre and Post-exposure Prophylaxis Awareness and Acceptability Among Sex Workers in Jamaica: A Cross-Sectional Study

The HIV prevention cascade is understudied among sex workers in Jamaica, where sex work and same sex practices are criminalized. We implemented a cross-sectional survey with cisgender women, transgender women, and cisgender men sex workers in Jamaica. We conducted multivariable logistic regression analyses to identify factors associated with PrEP and PEP awareness and acceptability. Participants (n = 340) included cisgender men (n = 124), transgender women (n = 101), and cisgender women (n = 115). PEP awareness was low (33.2%), yet acceptability was high (70.8%). In multivariable analyses, recent sexual violence, recent client violence, and sex work social cohesion were associated with PEP awareness and acceptability. One-third (32.7%) reported PrEP awareness, with high acceptability (80.2%). Relationship status and recent physical violence were associated with PrEP awareness and acceptability. In multivariable analyses, gender identity was not associated with differences in PEP/PrEP awareness/acceptability. Findings highlight the need to increase PEP and PrEP awareness and access among sex workers in Jamaica.

Actions taken by female sex workers (FSWs) after condom failure in semi urban Blantyre, Malawi

Background

Little is known about actions taken by female sex workers (FSWs) after male condom failure during male–female sexual intercourse. The objective of this study was to investigate the actions taken by FSWs after condom failure among FSWs in semi-urban, Blantyre in Malawi.

Methods

A cross sectional, qualitative study was conducted among FSWs in Blantyre, Malawi between May and July 2019. Snowballing technique was used to recruit study participants in four purposively selected study sites. Focus group discussions and in-depth interviews were conducted by trained research assistants among 40 FSWs. Data were analyzed using thematic content analysis.

Results

Study participants reported having taken different actions after condom failure. Out of 18 FSWs who experienced condom failure, 10 reported to have stopped sex immediately and changed the condom and then resumed afterwards. They reported to have douched, urinated, and/or squatted to prevent pregnancy, sexually transmitted infections (STIs) and HIV acquisition. Five study participants reported to have asked for extra pay from the client; 10 FSWs didn’t seek medical care. They thought the actions taken were enough for HIV and pregnancy prevention. Out of the 18 FSWs, only 3 stopped sexual intercourse completely and sought medical care which included post-exposure prophylaxis for HIV, STI treatment, and emergency contraceptives. Another 3 reported that they did not stop the sexual intercourse but only squatted and/or douched after sexual intercourse. The remaining 2 FSWs reported not to have stopped sexual intercourse and no any other actions were taken after the condom failure.

Conclusion

We report some inadequate behaviors among FSWs after condom failure. Health programs should develop interventions and support the performance of safer sex and actions after condom failure among FSWs to prevent STIs including HIV, and unplanned pregnancies. Interpersonal, structural and policy factors hindering FSWs’ access to perform effective interventions need to be addressed.

Low awareness and use of post-exposure prophylaxis among adolescents and young adults in South Africa: implications for the prevention of new HIV infections

The vulnerability of adolescents and young adults in South Africa to HIV and sexual violence is well documented. Post-exposure prophylaxis (PEP) is available for victims of sexual abuse in the country but awareness of this measure is required to maximise its HIV-prevention benefits. This study examined levels of PEP awareness and its correlates and the uptake of PEP among 772 students (16-24 years) in a South African university using stratified random sampling. Overall, we included more females (477) than males (295), reflecting the male-female ratio at the university. Adjusted and unadjusted logistic regression models were used to determine correlates of PEP awareness, which was low (24.1%), particularly among those who experienced sexual violence in the past year (19.8%) compared those who had not (24.8%). Only 2.6% of participants had used PEP, while 7.5% had seen it, and 14.6% knew where to get it. In the adjusted model, adequate family support (AOR: 2.22; CI: 1.54-3.20) and prior HIV testing (AOR: 2.65; CI: 1.59-4.42) were associated with a higher likelihood of PEP awareness. The study concluded that awareness of PEP was low in the study setting and especially among those who need it. Social marketing of PEP is needed in the study settings to realise the maximum benefits of PEP in preventing new HIV infections.

Uptake and retention on HIV pre-exposure prophylaxis among key and priority populations in South-Central Uganda

INTRODUCTION

Pre-exposure prophylaxis (PrEP) programmes have been initiated in sub-Saharan Africa to prevent HIV acquisition in key populations at increased risk. However, data on PrEP uptake and retention in high-risk African communities are limited. We evaluated PrEP uptake and retention in HIV hyperendemic fishing villages and trading centres in south-central Uganda between April 2018 and March 2019.

METHODS

PrEP eligibility was assessed using a national risk screening tool. Programme data were used to evaluate uptake and retention over 12 months. Multivariable modified Poisson regression estimated adjusted prevalence ratios (aPR) and 95% Confidence intervals (CIs) of uptake associated with covariates. We used Kaplan-Meier analysis to estimate retention and multivariable Cox regression to estimate adjusted relative hazards (aRH) and 95% CIs of discontinuation associated with covariates.

RESULTS AND DISCUSSION

Of the 2985 HIV-negative individuals screened; 2750 (92.1 %) were eligible; of whom 2,536 (92.2%) accepted PrEP. Male (aPR = 0.91, 95% CI = 0.85 to 0.97) and female (aPR = 0.85, 95% CI = 0.77 to 0.94) fisher folk were less likely to accept compared to HIV-discordant couples. Median retention was 45.4 days for both men and women, whereas retention was higher among women (log rank, p < 0.001) overall. PrEP discontinuation was higher among female sex workers (aRH = 1.42, 95% CI = 1.09 to 1.83) and female fisher folk (aRH = 1.99, 95% CI = 1.46 to 2.72), compared to women in discordant couples. Male fisher folk (aRH = 1.37, 95% CI = 1.07 to 1.76) and male truck drivers (aRH = 1.49, 95% CI = 1.14 to 1.94) were more likely to discontinue compared to men in discordant couples. Women 30 to 34 years tended to have lower discontinuation rates compared to adolescents 15 to 19 years (RH = 0.78 [95% CI = 0.63 to 0.96]).

CONCLUSIONS

PrEP uptake was high, but retention was very low especially among those at the highest risk of HIV: fisher folk, sex workers and truck drivers and adolescent girls. Research on reasons for PrEP discontinuation could help optimize retention.

Characterizing PrEP Awareness and Interest Among Filipina Transgender Women

Pre-exposure prophylaxis (PrEP) can efficaciously avert HIV acquisition for individuals at risk, including transgender individuals (trans) in the Philippines. We conducted multivariate logistic regression procedures in an online sample of Filipina trans women (n = 139) to examine associations of PrEP awareness. In this sample, 53% of Filipina trans women were unaware of PrEP, but almost all (93%) expressed interest in taking PrEP once learning about it. Greater odds of PrEP awareness was associated with discussion of HIV services with their health care providers, higher HIV knowledge, and discussion of PrEP among trans friends. Lower odds of PrEP awareness was associated with reporting being currently unemployed. The findings underscore a subset of trans women who might be early adopters of PrEP, and highlight PrEP inequities among trans women most marginalized, including those who are unemployed and have engaged in sex work.

The PrEP Care Continuum Among Cisgender Women Who Sell Sex and/or Use Drugs Globally: A Systematic Review

HIV prevalence among cisgender female sex workers (FSW) and/or women who use drugs (WWUD) is substantially higher compared to similarly aged women. Consistent with PRISMA guidelines, we conducted the first systematic review on the pre-exposure prophylaxis (PrEP) continuum among FSW and/or WWUD, searching PubMed, Embase, CINAHL, PsycInfo, and Sociological Abstracts. Eligibility criteria included: reporting a PrEP related result among FSW and/or WWUD aged 18 + ; peer-reviewed; and published in English between 2012 and 2018. Our search identified 1365 studies; 26 met eligibility requirements, across the following groups: FSW (n = 14), WWUD (n = 9) and FSW-WWUD (n = 3). Studies report on at least one PrEP outcome: awareness (n = 12), acceptability (n = 16), uptake (n = 4), and adherence (n = 8). Specific barriers span individual and structural levels and include challenges to daily adherence, cost, and stigma. Combining health services and long-acting PrEP formulas may facilitate better PrEP uptake and adherence. The limited number of studies indicates a need for more research.

A Review of Pre-Exposure Prophylaxis Adherence among Female Sex Workers

Globally and in Africa specifically, female sex workers (FSWs) are at an extraordinarily high risk of contracting human immunodeficiency virus (HIV). Pre-exposure prophylaxis (PrEP) has emerged as an effective and ethical method with which to prevent HIV infection among FSWs. PrEP efficacy is, however, closely linked to adherence, and adherence to PrEP among FSWs is a complex and interrelated process that has been shown to be of importance to public health policies and HIV control and intervention programs. This comprehensive review categorizes barriers to and facilitators of adherence to HIV PrEP for FSWs, and describes five strategies for promoting PrEP adherence among FSWs. These strategies encompass 1) a long-term educational effort to decrease the stigma associated with sex work and PrEP use, 2) education on how PrEP works, 3) lifestyle modification, 4) research on next-generation PrEP products to address the inconvenience of taking daily pills, and 5) integration of PrEP into existing services, such as social services and routine primary care visits, to reduce the economic burden of seeking the medication. Our review is expected to be useful for the design of future PrEP intervention programs. Multidisciplinary intervention should be considered to promote PrEP adherence among FSWs in order to help control the HIV epidemic.

High pre-exposure prophylaxis awareness and willingness to pay for pre-exposure prophylaxis among young adults in Western Kenya: results from a population-based survey

We conducted a population-level short message service (SMS)-based survey among individuals aged 18–34 years in six HIV high-burden counties in Western Kenya to assess pre-exposure prophylaxis (PrEP) awareness, acceptability of non-facility PrEP delivery, and willingness to pay for PrEP. In January 2019, anonymous data were collected using mSurvey Inc., Nairobi, Kenya, which sends SMS messages via mobile provider networks to a ‘general audience’ pool of subscribers ≥18 years. Subscribers’ demographic information was matched to Kenyan census data by age, gender, and county. Of the 3825 individuals who received the survey, 2617 (68%) opened the survey and 2498/2617 (95%) completed all questions. Overall, 84% had ever heard of PrEP, of whom 59% demonstrated understanding of PrEP; understanding was greater among men than women (64% versus 55%, p < 0.001). Among participants who understood PrEP (n = 1249), 38% reported pharmacies (informal or formal) as the preferred venue to obtain PrEP. Over half (61%) were willing to pay for PrEP and 78% reported that the maximum amount they were willing to pay for a one-month supply was <5 USD. High awareness of PrEP in high HIV prevalence settings in Kenya suggests effective public health messaging. Willingness to pay and preference for pharmacy access suggest that non-facility PrEP delivery may be useful.

"I Couldn't Afford to Resist": Condom Negotiations Between Male Sex Workers and Male Clients in Mombasa, Kenya

Male sex workers in Kenya face a disproportionate burden of HIV and often engage in condomless sex with their commercial partners, yet little is known about how condom negotiations between male sex workers and clients take place. We conducted semi-structured interviews with 25 male sex workers and 11 male clients of male sex workers in Mombasa, Kenya, to examine barriers and facilitators to condom use and how condom use negotiation takes place in these interactions. Participants reported positive attitudes toward condom use and perceived condom use to be a health-promoting behavior. Barriers to condom use included extra-payment for condomless sex, low perceived HIV/STI risk with some sexual partners, perceived reduced pleasure associated with using condoms, alcohol use, and violence against male sex workers by clients. Future interventions should address individual- and structural-level barriers to condom use to promote effective condom use negotiation between male sex workers and male clients.

Barriers to Accessing Sexual Health Services for Transgender and Male Sex Workers: A Systematic Qualitative Meta-summary

Access to safe and effective sexual healthcare services for transgender and male sex workers (TMSW) is a human right. Globally, TMSW experience a higher prevalence of human immunodeficiency virus (HIV) and sexually transmitted infections than the general population or other sex workers, suggesting the existence of unique challenges for this group when accessing healthcare. A systematic database search identified 22 qualitative papers addressing barriers to accessing sexual healthcare services for TMSW. These papers were critically evaluated for adherence to best practice standards for qualitative research and research with sex workers. A coding process identified five themes. Stigma was the predominant barrier, and was divided into stigma related to sexuality, gender identity, HIV status, sex worker status, and internalised stigma. Other barriers were confidentiality concerns, sexual health literacy, fatalism, and structural barriers. Each of these themes were informed by the wider context of stigma. The literature presents a complex syndemic of social disadvantage and exclusion acting to produce and reinforce health disparities related to sexual health and access to screening and treatment for TMSW.

Perspectives on oral pre-exposure prophylaxis use amongst female sex workers in Harare, Zimbabwe

BACKGROUND

Pre-exposure prophylaxis (PrEP) could provide protection from human immunodeficiency virus (HIV) infection in sexually active persons at risk. Limited data are available in Zimbabwe with regard to the perceptions about PrEP amongst female sex workers (FSWs).

OBJECTIVES

The aim of this study was to evaluate the knowledge levels of oral PrEP and the likelihood of its use amongst FSWs.

METHOD

This was a cross-sectional study in the peri-urban areas of Harare, Zimbabwe. Human immunodeficiency virus-negative FSWs were interviewed to assess their awareness of and likelihood to use PrEP. The relative importance index was used to evaluate the levels of knowledge and the likelihood of, and barriers to, PrEP use. A set of 10 questions was designed and validated that evaluated participants' understanding of PrEP. A bivariate logistic regression model was utilised to identify predictors of PrEP use.

RESULTS

A total of 131 FSWs with a median age of 25 years (interquartile range: 21-31) participated in this study. Of the 71 (54%) FSWs who had heard about PrEP, 46 (35%) participants had adequate knowledge of its use. A total of 102 (78%) participants revealed that they would be willing to continuously use PrEP if it was provided free of cost. Increasing age of the participants was associated with an increase in the likelihood of using PrEP (r = 0.0033, p = 0.038). More knowledge about PrEP increased the likelihood of its use (r = 0.21, p = 0.0153). This likelihood increased amongst participants with an unprotected sexual intercourse encounter in the preceding 3 months (r = 0.0448, p = 0.026).

CONCLUSION

Knowledge of PrEP amongst FSWs was low. To increase the uptake of PrEP, there is a need to further sensitise FSWs about this intervention. Programmes should also promote awareness training in FSW subgroups that are less likely to use PrEP.

The Ashodaya PrEP project: Lessons and implications for scaling up PrEP from a community-led demonstration project among female sex workers in Mysore, India

To inform PrEP roll out, Ashodaya Samithi, a sex workers' collective, conducted a community-led prospective demonstration project among female sex workers in Mysore and Mandya, India. Following a community preparedness phase and pre-screening, participants were recruited for clinical screening and enrolment, provided PrEP as part of combination HIV prevention, and followed for 16 months. Adherence was measured by self-reported pill intake and by tenofovir blood level testing among a subset of participants. Of the 647 participants enrolled, 640 completed follow-up. Condom use remained stable and no HIV seroconversions occurred. Self-reported daily PrEP intake over the last month was 97.97% at the end of the study. Tenofovir blood levels >40 ng/mL (consistent with steady state dosing) were detected among 80% (n = 68/85) and 90.48% (n = 76/84) of participants at month 3 and 6, respectively. Our study holds important insights for rolling out PrEP in community settings as part of targeted HIV prevention interventions.

Sexual health needs of female sex workers in Côte d'Ivoire: a mixed-methods study to prepare the future implementation of pre-exposure prophylaxis (PrEP) for HIV prevention

OBJECTIVE

To describe sexual and reproductive health (SRH) needs of female sex workers (FSWs) to inform the future implementation of pre-exposure prophylaxis (PrEP) for HIV prevention in this population.

DESIGN AND SETTING

The ANRS 12361 PrEP-CI cross-sectional and mixed-methods study was designed and implemented with two community-based organisations in Côte d'Ivoire.

PARTICIPANTS

A convenience sample of 1000 FSWs aged ≥18, not known as HIV-positive, completed a standardised questionnaire assessing sociodemographic characteristics, sexual practices, use of community health services and a priori acceptability of PrEP. Twenty-two indepth interviews and eight focus group discussions were also conducted to document FSWs' risky practices and sexual behaviours, experiences with violence and discrimination, attitudes regarding HIV and sexually transmitted infections (STIs), and barriers to SRH services.

RESULTS

Although 87% described consistent condom use with clients, more than 22% declared accepting condomless sexual intercourse for a large sum of money. Furthermore, condom use with their steady partner and knowledge of their partner's HIV status were low despite their acknowledged concurrent sexual partnerships. While inconsistent condom use exposed FSWs to STIs and undesired pregnancies, the prevalence of contraceptive strategies other than condoms was low (39%) due to fear of contraception causing sterility. FSWs faced obstacles to accessing SRH care and preferred advice from their peers or self-medication.

CONCLUSIONS

Despite adoption of preventive behaviour in most cases, FSWs are still highly exposed to HIV. Furthermore, FSWs seem to face several barriers to accessing SRH. Implementing PrEP among FSWs in West Africa, such as in Côte d'Ivoire, constitutes an opportunity to consider the regular follow-up of HIV-negative FSWs. PrEP initiation should not condition access to SRH services; conversely, SRH services could be a way to attract FSWs into HIV prevention. Our results highlight the importance of developing a people-focused approach that integrates all SRH needs when transitioning from PrEP efficacy trials to implementation.

"I Do Try To Use Condoms, But…": Knowledge and Interest in PrEP Among Male Sex Workers in Mexico City

In Mexico City, male sex workers (MSWs) are up to 126 times more likely to be living with HIV than the general public. We conducted interviews with 23 MSWs in Mexico City to examine their subjective understandings about their sexual risk behaviors and explore opportunities about HIV pre-exposure prophylaxis (PrEP) as a prevention approach in this group. Despite knowledge about sexual HIV risks, most participants reported condomless anal sex with clients. There was very little prior knowledge about PrEP, but very high interest in using a daily pill for prevention. Several participants expected an increase in condomless anal sex if taking PrEP, because of monetary incentives from clients or a perceived increase in pleasure. Additionally, seasonal sex workers expressed interest in using PrEP only during months when they were performing sex work. PrEP implementation efforts through Mexico's healthcare system should recognize the varying needs and sexual risk behaviors of MSWs.

"The Drug Will Help Protect My Tomorrow": Perceptions of Integrating PrEP into HIV Prevention Behaviors Among Female Sex Workers in Lilongwe, Malawi

Female sex workers (FSW) are disproportionately at risk for HIV. Pre-exposure prophylaxis (PrEP) is an effective HIV prevention method, yet approaches for incorporating PrEP within prevention strategies used by FSW are lacking. Semistructured focus group discussions were conducted with 44 HIV-negative FSW in Lilongwe, Malawi to explore perceptions of PrEP: acceptability, integration within HIV prevention behaviors, and barriers to use. Acceptability of PrEP was high. Motivation to use PrEP was rooted in love for one's life, anticipated negative economic effects associated with HIV acquisition. PrEP was viewed as complementary to existing norms for engaging in healthy sexual behaviors. Many felt PrEP may provide extra protection from HIV, along with condoms and frequent STI testing. Unpredictable daily lives, stigma, and side effects were barriers that could affect PrEP use. Leveraging existing HIV prevention strategies and social norms surrounding HIV prevention behaviors may positively impact PrEP uptake among FSW in Malawi and sub-Saharan Africa.

Low awareness and use of pre-exposure prophylaxis among adolescents and young adults in high HIV and sexual violence prevalence settings

South Africa has adopted pre-exposure prophylaxis (PrEP) as a preventive strategy for populations at-risk for HIV, though uptake is low among adolescents and young adults. We examined the awareness and use of PrEP among adolescents and young adults in the Eastern Cape, South Africa.This cross-sectional study was conducted between June and November 2018 among 772 adolescents and young adults (aged 16-24 years) selected using stratified random sampling in a South African university. An electronic self-administered questionnaire was used to elicit demographic information, behavioral, family-related characteristics, awareness and use of PrEP. Adjusted and unadjusted logistic regression models were used to examine the predictors of PrEP awareness.The overall level of PrEP awareness was 18.8%; however, only 1.7% of participants had used PrEP, 7.5% of had seen it, 4.8% knew how much it cost, and 14.8% knew where and how to get it. In the adjusted regression analysis, only adequate family support (AOR: 2.11; CI: 1.47-3.04) and discussions of HIV and sexually transmitted infections with sexual partners (AOR: 1.78; CI: 1.19-2.67) were associated with a higher likelihood of being aware of PrEP.The level of awareness and use of PrEP is still very low among adolescents and young adults who may need it to prevent HIV infection. Poor awareness of PrEP among adolescents and young adults in high HIV risk settings may limit its use. Thus, concerted efforts are needed to promote awareness and access to PrEP among young South African adults.

Factors associated with knowledge of pre-exposure prophylaxis in pregnant women in Cape Town, South Africa

Pregnant and postpartum women in Southern Africa are at increased risk of HIV infection. Pre-exposure prophylaxis in pregnancy and postpartum periods could significantly reduce the risk of HIV acquisition and transmission in pregnancy. Participants at a community health clinic in Cape Town completed a survey about demographic and sexual risk behaviors, and prior knowledge of pre-exposure prophylaxis. We evaluated factors associated with knowledge of pre-exposure prophylaxis using multivariable logistic regression. We enrolled 50 pregnant and 37 postpartum women, of whom 51% were HIV-uninfected. Twenty-nine (33%) knew about pre-exposure prophylaxis, most from their healthcare provider (69%). Older age (adjusted odds ratio [aOR]/year = 1.09, 95% CI = 1.00–1.19), unintended pregnancy (aOR = 3.36, 95% CI = 1.06–12.12), and more than one sex partner in the last year (aOR = 5.31, 95% CI = 1.12–30.07) were associated with pre-exposure prophylaxis knowledge. Our study identified low levels of pre-exposure prophylaxis knowledge in pregnant and breastfeeding women, but increased knowledge in higher risk women. These results provide guidance to develop interventions to increase pre-exposure prophylaxis knowledge and uptake.

A Review of Approaches Used to Increase Awareness of Pre-exposure Prophylaxis (PrEP) in the United States

PrEP is an important and useful HIV prevention strategy, yet awareness remains low among at-risk populations in the United States and elsewhere in the world. As previous studies have shown PrEP awareness to be important to PrEP uptake, understanding approaches to increase PrEP awareness is imperative. The current systematic review provides an overview of published articles and on-going research on PrEP awareness. Using PRISMA guidelines, two published articles and seven on-going research studies were identified that use different approaches to increase PrEP awareness. Findings highlight the need for research to target other at-risk populations and geographic areas. Future research should consider the use of technology and network approaches to assess whether they lead to increased awareness, accurate knowledge, and uptake of PrEP, along with examining which messaging works best for specific targeted, at-risk population(s).

Understanding user perspectives of and preferences for oral PrEP for HIV prevention in the context of intervention scale-up: a synthesis of evidence from sub-Saharan Africa

INTRODUCTION

Oral pre-exposure prophylaxis (PrEP) for HIV prevention has been proven to significantly reduce new HIV infections yet scale-up has been slow. As contexts continue to adjust to make space for PrEP, it is crucial to understand the perspectives and experiences of potential end-users. In order to inform PrEP and demand creation interventions, this paper examines personal perspectives on adopting and using PrEP among HIV at-risk populations in sub-Saharan Africa.

METHODS

Using the principles of a scoping review in July 2018, we explored the extent, range, and nature of published literature regarding PrEP uptake and use among; men who have sex with men, HIV serodiscordant couples, adolescent girls and young women, pregnant and breastfeeding women, women partners of migrant workers; and people who use drugs. Steps included: identification of the research question; identification of relevant studies; study selection; charting the data; and collation - summarizing and reporting results. PubMed and PsycInfo were searched for papers relating to PrEP uptake and use in sub-Saharan Africa. Resulting papers were reviewed with data extracted and compiled in Excel for analysis. A broad content analysis was conducted and organized into high-level themes.

RESULTS AND DISCUSSION

Thirty-five papers were included in this review. There was little opposition in general to oral PrEP; however, there were significant nuances in its broader acceptability, applicability, and usability. We identified five themes within which these are discussed. These relate to balancing complexities of personal empowerment and stigma; navigating complex risk environments; influences of relationships and partners; efficacy and side effects; and practicalities of use. This body of research suggests that while product attributes and the logistics of PrEP delivery and use are important topics, it is vital to consider stigma, the interactions of PrEP use with relationships, and the need for broader understanding of ARVs for prevention versus treatment.

CONCLUSIONS

Planning for, programming and promoting the adoption of oral PrEP necessitates a deeper understanding of end-user priorities in order to ensure successful interventions. This review illustrates the nuances facilitating or deterring PrEP use that may affect the larger effort of PrEP scale-up.

PrEP and the syndemic of substance use, violence, and HIV among female and male sex workers: a qualitative study in Kisumu, Kenya

INTRODUCTION

Female and male sex workers experience heightened vulnerability to HIV and other health harms that are compounded by substance use, physical and sexual violence, and limited access to health services. In Kisumu, Kenya, where sex work is widespread and substance use is a growing public health concern, offering pre-exposure prophylaxis (PrEP) for HIV prevention could help curtail the HIV epidemic. Our study examines "syndemics," or mutually reinforcing epidemics of substance use, violence and HIV, in relation to PrEP acceptability and feasibility among female and male sex workers in Kenya, one of the first African countries to approve PrEP for HIV prevention.

METHODS

From 2016 to 2017, sex workers in Kisumu reporting recent alcohol or drug use and experiences of violence participated in qualitative interviews on HIV risk and perspectives on health service needs, including PrEP programming. Content analysis identified themes relating to PrEP knowledge, acceptability, access challenges and delivery preferences.

RESULTS

Among 45 female and 28 male sex workers, median age was 28 and 25 respectively. All participants reported past-month alcohol use and 91% of women and 82% of men reported past-month drug use. Violence was pervasive, with most women and men reporting past-year physical (96% women, 86% men) and sexual (93% women, 79% men) violence. Concerning PrEP, interviews revealed: (1) low PrEP knowledge, especially among women; (2) high PrEP acceptability and perceived need, particularly within syndemic contexts of substance use and violence; and (3) preferences for accessible, non-stigmatizing PrEP delivery initiatives designed with input from sex workers.

CONCLUSIONS

Through a syndemic lens, substance use and violence interact to increase HIV vulnerability and perceived need for PrEP among female and male sex workers in Kisumu. Although interest in PrEP was high, most sex workers in our sample, particularly women, were not benefiting from it. Syndemic substance use and violence experienced by sex workers posed important barriers to PrEP access for sex workers. Increasing PrEP access for sex workers will require addressing substance use and violence through integrated programming.

Awareness and Interest in HIV Pre-Exposure Prophylaxis Among Street-Based Female Sex Workers: Results from a US Context

Pre-exposure prophylaxis (PrEP) has the potential to be an empowering HIV prevention tool among female sex workers (FSW), yet little is known about PrEP awareness and interest in this population. Sex workers and Police Promoting Health in Risky Environments (SAPPHIRE) is a prospective cohort study of street-based FSW in Baltimore, MD. A cross-sectional analysis explored awareness and interest in PrEP among HIV-negative FSW. Multivariable Poisson regressions modeled associations between individual, interpersonal, and structural variables and PrEP awareness and interest. Of n = 232 FSW, 66% were white, half were less than 35 years old, 59% injected drugs daily, and 66% sold sex daily. Only 21% of FSW were aware of PrEP, though 74% were interested. PrEP awareness was associated with experiencing client condom coercion [adjusted incidence rate ratio (aIRR) = 0.50, 95% CI: 0.28-0.90] and condomless sex with an intimate partner (aIRR = 0.54, 95% CI: 0.30-0.98). PrEP interest was associated with perceiving PrEP as "very easy" to take (aIRR = 1.91, 95% CI: 1.49-2.45) and moving to an unfamiliar geographic area to sell sex (aIRR = 1.20, 95% CI: 1.04-1.39). Women who had a current gonorrhea or chlamydia infection were less likely to be interested in PrEP (aIRR = 0.75, 95% CI: 0.59-0.95). Though PrEP awareness among FSW is low, there are FSW who are significantly more likely to express interest in PrEP and outreach efforts should target these women. Results suggest that women-controlled HIV prevention methods may be important for reducing incidence among FSW.

Acceptability of Antiretroviral Pre-exposure Prophylaxis from a Cohort of Sexually Experienced Young Transgender Women in Two U.S. Cities

Emtricitabine/tenofovir disoproxil fumarate as pre-exposure prophylaxis (PrEP) can prevent HIV infection among at-risk individuals, including young transgender women (YTW). We used baseline data from 230 HIV-uninfected YTW (ages 16-29 years) who were enrolled in Project LifeSkills during 2012-2015. We examined factors associated with perceived acceptability of PrEP use (mean score = 23.4, range 10.0-30.0). Participants were largely transgender women of color (67%) and had a mean age of 23 years (SD = 3.5). In an adjusted multiple linear regression model, PrEP interest (β = 3.7, 95% CI 2.2-5.2) and having a medical provider who meets their health needs (β = 2.9, 95% CI 1.3-4.4) was associated with higher PrEP acceptability scores, whereas younger age (21-25 vs 26-29 years) (β = -2.0, 95% CI - 3.6 to - 0.4) and reporting transactional sex in the past 4 months (β = - 1.5, 95% CI - 3.0 to - 0.1) was associated with lower PrEP acceptability scores (all p values < 0.05). Enhancing PrEP-related interventions by addressing the unique barriers to uptake among YTW of younger age or those with history of transactional sex could bolster PrEP acceptability for this population.
