In a tragically ironic twist, antiretroviral therapy (ART) that promised an end to AIDS ushered in a syndemic of viral cancers, transforming hope to despair. In this article we draw from the illness narratives of HIV positive women attending a cervical cancer screening clinic in Johannesburg, South Africa, and chart their pathways from HIV to cancer, and their quest for treatment. Our interlocutors described protracted struggles to access surgical procedures to prevent the onset of cervical cancer.

The FACTS 001 trial found that vaginal pre- and post-coital application of 1% tenofovir gel did not prevent HIV-1 infection amongst young South African women. The trial included a multi-faceted approach to adherence support and collected objective and self-reported adherence measures. Using qualitative data collected from a random sub-set of FACTS 001 participants (135 in-depth interviews at product discontinuation and 13 focus group discussions at dissemination of trial results), we explore the importance of 'place' and 'timing' in shaping acts of sexual intimacy and product adherence.

Background: Risk perception has been found to be a crucial factor explaining inconsistent or non-use of HIV prevention interventions. Considerations of risk need to expand beyond risk of infection to also include the personal, social, emotional, and economic risks associated with prevention intervention use.

Objectives: This systematic review of qualitative peer-reviewed literature from sub-Saharan Africa examines perceptions of risk associated with HIV infection and HIV prevention intervention use.

During a five-day workshop, former clinical trial participants and local musicians wrote the lyrics and recorded a song about an HIV prevention trial. Born of concerns about misconceptions regarding experimental drug trials, the aim was to engender engagement with medical researchers and open dialogue about the risks and benefits of trial participation. Composing lyrics that highlighted their credibility as communicators of medical scientific knowledge and their selfless sacrifice to stem the transmission of HIV, women performed their social positioning and cultural authority in contrast to men as well as other women not part of the trial.

Background: In sub-Saharan Africa, there is growing interest in the use of cash transfer (CT) programs for HIV treatment and prevention. However, there is limited evidence of the consequences related to CT provision to adolescents in low-resourced urban settings. We explored the experiences of adolescents receiving CTs to assess the acceptability and unintended consequences of CT strategies in urban Johannesburg, South Africa.

This commentary constructs a social history of Hillbrow, an inner-city suburb in Johannesburg, South Africa, based on a review of relevant published historical, anthropological and sociological texts. We highlight the significant continuities in the social structure of the suburb, despite the radical transformations that have occurred over the last 120 years.Originally envisaged as a healthy residential area, distinct from the industrial activity of early Johannesburg, Hillbrow was a prime location for health infrastructure to serve the city.

Background: For adolescents growing up in poor urban South African settings, violence is often a part of daily life and has lasting effects on physical and mental health outcomes in adulthood. We conducted a qualitative study to document and understand the forms of interpersonal violence experienced by adolescents living in Hillbrow, Johannesburg. In this article, we explore how violence is experienced differently by adolescent boys and girls, how they conceptualise 'dangerous' and 'safe' spaces in their neighbourhood and what gaps exist in available services for youth in Hillbrow.

Background: Developing an effective HIV vaccine is the overriding priority for HIV prevention research. Enrolling and maintaining cohorts of men into HIV vaccine efficacy trials is a necessary prerequisite for the development and licensure of a safe and efficacious vaccine.

Methods: One hundred-fifty consenting HIV-negative men were enrolled into a pilot 1:1 randomised controlled trial of immediate vaccination with a three-dose hepatitis B vaccine compared to deferred vaccination (at 12 months) to investigate feasibility and acceptability of a future HIV vaccine trial in this population.

Background: Unmanaged urban growth in southern and eastern Africa has led to a growth of informal housing in cities, which are home to poor, marginalised populations, and associated with the highest HIV prevalence in urban areas. This article describes and reflects on the authors' experiences in designing and implementing an HIV intervention originally intended for migrant men living in single-sex hostels of inner-city Johannesburg. It shows how formative research findings were incorporated into project design, substantially shifting the scope of the original project.

The lie has been presented as a performance that protects identities against moral judgment in the context of power imbalances. We explore this assertion from the perspective of a pre-exposure prophylaxis trial to prevent HIV for African women in South Africa, in which context biological evidence of widespread lying about product adherence was produced, resulting in a moral discourse that opposed altruistic and selfish motivations. In this article, we seek to understand the meaning of the lie from the perspective of women trial participants.

Female-initiated methods of HIV prevention are needed to address barriers to HIV prevention rooted in gender inequalities. Understanding the sociocultural context of pre-exposure prophylaxis (PrEP) trials, including gender-based violence, is thus critical. MTN-003C (VOICE-C), a qualitative sub-study of the larger MTN-003 (VOICE) trial, examined sociocultural barriers and facilitators to PrEP amongst women in Johannesburg.

Little is known about how menstruation is managed in low-income settings and whether existing sanitation systems meet women's needs. Using the 'Photovoice' method with 21 women in participatory workshops and in-depth interviews, we collected data on menstrual hygiene management in three sites in Durban, South Africa. All women reported using disposable sanitary pads.

Background: Women in sub-Saharan Africa are disproportionately affected by high rates of HIV, yet relatively few products exist for female-initiated HIV prevention. New antiretroviral (ARV)-based prevention options could present opportunities for women to expand their HIV prevention choices; however, acceptability and adherence play a key role in the effectiveness of these products and implementation is still in early stages. To better understand which HIV prevention options might best serve women in sub-Saharan Africa, how and why, this review will explore qualitative evidence from clinical trials and implementation studies alike using a meta-ethnographic approach to synthesise data and interpret results.

There is widespread evidence that male partners influence women's ability and willingness to join HIV prevention trials and to use female-controlled prevention strategies such as microbicide gels. VOICE-C was an ancillary study to the Microbicide Trials Network's VOICE trial at the Johannesburg site that explored social and structural factors influencing women's use of study tablets and vaginal gel. Qualitative data were analyzed from 102 randomly-selected VOICE participants interviewed through in-depth interviews (IDI, n = 41); ethnographic interviews (n = 21) or focus group discussions (FGD, n = 40) and 22 male partners interviewed in 14 IDI and 2 FGD.

Introduction: Antiretroviral (ARV)-based pre-exposure prophylaxis (PrEP) is a promising new HIV prevention strategy. However, variable levels of adherence have yielded mixed results across several PrEP trials and populations. It is not clear how taking ARV - traditionally used for HIV treatment - is perceived and how that perception may affect the use of these products as preventives.

Background: During the Microbicides Development Program (MDP) 301, a clinical trial of a candidate microbicide amongst women in Johannesburg, South Africa, we used community radio to promote awareness of the trial, to inform community members about specific medical research procedures and terminologies, and to stimulate dialogue between researchers and local citizens.

Methods: We used mixed methods to undertake a retrospective analysis of the social responses to the radio shows, focusing specifically on recruitment and participation in the MDP301 trial. We collected quantitative data that describes the themes and listener responses, the costs per broadcast, and the impact of the radio broadcasts on trial recruitment.

Background: Although significant progress has been made in clinical trials of women-controlled methods of HIV prevention such as microbicides and Pre-exposure Prophylaxis (PrEP), low adherence to experimental study products remains a major obstacle to being able to establish their efficacy in preventing HIV infection. One factor that influences adherence is the ability of trial participants to attend regular clinic visits at which trial products are dispensed, adherence counseling is administered, and participant safety is monitored. We conducted a qualitative study of the social contextual factors that influenced adherence in the VOICE (MTN-003) trial in Johannesburg, South Africa, focusing on study participation in general, and study visits in particular.

In a context of high rates of intimate partner violence (IPV), trials of female-controlled technologies for HIV prevention such as microbicides may increase the possibility of social harms. Seeking to explore the relationship between IPV and microbicide use further, this paper documents women's narratives of participating in the Microbicide Development Program (MDP) trial in Johannesburg, South Africa, and experiences of partner violence and conflict. A social science sub-study, nested within the trial, was conducted between September 2005 and August 2009, and 401 serial in-depth-interviews were undertaken with 150 women.

Background: In VOICE, a multisite HIV pre-exposure prophylaxis (PrEP) trial, plasma drug levels pointed to widespread product nonuse, despite high adherence estimated by self-reports and clinic product counts. Using a socio-ecological framework (SEF), we explored socio-cultural and contextual factors that influenced participants' experience of daily vaginal gel and oral tablet regimens in VOICE.

Methods: In Johannesburg, a qualitative ancillary study was concurrently conducted among randomly selected VOICE participants assigned to in-depth interviews (n = 41), serial ethnographic interviews (n = 21), or focus group discussions (n = 40).

Background: Cognitive mapping is a participatory research methodology that documents, in visual form, a construct of the local environment in which people live and work. We adapted this method to provide detailed data about study locales to inform recruitment and retention strategies for HIV prevention community based clinical trials.

Methods: Four cognitive mapping studies were undertaken between 2005 and 2010, in and around Johannesburg in Orange Farm, and Hillbrow.

As clinical trial research increasingly permeates sub-Saharan Africa, tales of purposeful HIV infection, blood theft, and other harmful outcomes are widely reported by participants and community members. Examining responses to the Microbicide Development Programme 301-a randomized, double-blind, placebo-controlled microbicide trial-we investigate the ways in which these accounts embed medical research within postcolonial contexts. We explore three popular narratives circulating around the Johannesburg trial site: malicious whites killing participants and selling their blood, greedy women enrolling in the trial solely for financial gain, and virtuous volunteers attempting to ensure their health and aid others through trial participation.

Recognising that women often have little control over most HIV-prevention methods, including condoms, researchers have made efforts to develop new bio-technological interventions, such as microbicides, that could allow women greater autonomy in HIV-prevention decision making. In many situations, women are unable to negotiate condom use with their partners, meaning that they could be better protected through the use of an effective microbicide. This paper uses qualitative data from the Microbicide Development Programme 301 (MDP301) microbicide trial in Johannesburg, South Africa.

Background: Communicating the results of randomised controlled trials may present challenges for researchers who have to work with communities and policy-makers to anticipate positive outcomes, while being aware that results may show no effect or harm.

Methods: We present a case study from the perspective of researchers in South Africa about the lessons learnt from communicating the results of four trials evaluating treatment for herpes simplex virus type 2 (HSV-2) as a new strategy for HIV prevention.

Results: We show that contextual factors such as misunderstandings and mistrust played an important role in defining the communications response.
