    SUMMARY Social indicators suggest that African American adolescents are in the highest risk categories of those contracting HIV/AIDS (CDC, 2001). The dramatic impact of HIV/AIDS on urban African American youth have influenced community leaders and policy makers to place high priority on programming that can prevent youth’s exposure to the virus (Pequegnat & Szapocznik, 2000). Program developers are encouraged to design programs that reflect the developmental ecology of urban youth (Tolan, Gorman-Smith, & Henry, 2003). This often translates into three concrete programmatic features: (1) Contextual relevance; (2) Developmental-groundedness; and (3) Systemic Delivery. Because families are considered to be urban youth’s best hope to grow up and survive multiple-dangers in urban neighborhoods (Pequegnat & Szapocznik, 2000), centering prevention within families may ensure that youth receive ongoing support, education, and messages that can increase their capacity to negotiate peer situations involving sex. This paper will present preliminary data from an HIV/AIDS prevention program that is contextually relevant, developmentally grounded and systematically-delivered. The collaborative HIV/AIDS Adolescent Mental Health Project (CHAMP) is aimed at decreasing HIV/AIDS risk exposure among a sample of African American youth living in a poverty-stricken, inner-city community in Chicago. This study describes results from this family-based HIV preventive intervention and involves 88 African American pre-adolescents and their primary caregivers. We present results for the intervention group at baseline and post intervention. We compare post test results to a community comparison group of youth. Suggestions for future research are provided.

    Latino youth are the fastest growing ethnic group in the United States and are at considerable risk for HIV and other sexually transmitted infections (STIs), given that they have an earlier onset of sexual activity and use condoms less consistently than European American adolescents. Theorists and scholars have emphasized the importance of taking culture into account in sexuality interventions with Latino adolescents, yet few culturally tailored interventions have been developed for this population. Given the emphasis on familismo and collectivism among Latinos, family-based programs are likely to be well received and could contribute to long-term maintenance of adolescent safety. In this synthesis of the relevant literature, cultural factors that have been identified as relevant to Latino sexuality are reviewed and implications for family-based intervention with Latinos are addressed.

We describe a CBPR study in rural Kenya to develop and pilot a family-based HIV prevention and mental health promotion intervention. Academic partners (APs) worked with a community advisory committee (CAC) during formative research, intervention development, and a pilot trial. Ethical challenges emerged related to: negotiating power imbalances between APs and the CAC; CAC members’ shifting roles as part of the CAC and wider community; and anticipated challenges in decision making about sustainability. Factors contributing to ethical dilemmas included low access to education, scarcity of financial resources, and the shortage of HIV-related services despite high prevalence. PMID:23651936

    SUMMARY This article describes a family-based HIV prevention and mental health promotion program specifically designed to meet the needs of perinatally-infected preadolescents and their families. This project represents one of the first attempts to involve perinatally HIV-infected youth in HIV prevention efforts while simultaneously addressing their mental health and health care needs. The program, entitled CHAMP+ (Collaborative HIV Prevention and Adolescent Mental Health Project-Plus), focuses on: (1) the impact of HIV on the family; (2) loss and stigma associated with HIV disease; (3) HIV knowledge and understanding of health and medication protocols; (4) family communication about puberty, sexuality and HIV; (5) social support and decision making related to disclosure; and (6) parental supervision and monitoring related to sexual possibility situations, sexual risk taking behavior and management of youth health and medication. Findings from a preliminary evaluation of CHAMP+ with six families are presented along with a discussion of challenges related to feasibility and implementation within a primary health care setting for perinatally infected youth.

    Family-based interventions with children who are affected by HIV and AIDS are not well established. The Collaborative HIV Prevention and Adolescent Mental Health Program (CHAMP) represents one of the few evidence-based interventions tested in low-income contexts in the US, Caribbean and South Africa. This paper provides a description of the theoretical and empirical bases of the development and implementation of CHAMP in two of these countries, the US and South Africa. In addition, with the advent of increasing numbers of children infected with HIV surviving into adolescence and young adulthood, a CHAMP+ family-based intervention, using the founding principles of CHAMP, has been developed to mitigate the risk influences associated with being HIV positive.

    Objective The objective of this study is to assess the feasibility and acceptability of an intervention to reduce mental health problems and bolster resilience among children living in households affected by caregiver HIV in Rwanda. Design Pre-post design, including 6-month follow-up. Methods The Family Strengthening Intervention (FSI) aims to reduce mental health problems among HIV-affected children through improved child–caregiver relationships, family communication and parenting skills, HIV psychoeducation and connections to resources. Twenty families (N=39 children) with at least one HIV-positive caregiver and one child 7–17 years old were enrolled in the FSI. Children and caregivers were administered locally adapted and validated measures of child mental health problems, as well as measures of protective processes and parenting. Assessments were administered at pre and postintervention, and 6-month follow-up. Multilevel models accounting for clustering by family tested changes in outcomes of interest. Qualitative interviews were completed to understand acceptability, feasibility and satisfaction with the FSI. Results Families reported high satisfaction with the FSI. Caregiver-reported improvements in family connectedness, good parenting, social support and children's pro-social behaviour (P<0.05) were sustained and strengthened from postintervention to 6-month follow-up. Additional improvements in caregiver-reported child perseverance/self-esteem, depression, anxiety and irritability were seen at follow-up (P<.05). Significant decreases in child-reported harsh punishment were observed at postintervention and follow-up, and decreases in caregiver reported harsh punishment were also recorded on follow-up (P<0.05). Conclusion The FSI is a feasible and acceptable intervention that shows promise for improving mental health symptoms and strengthening protective factors among children and families affected by HIV in low-resource settings.

    ABSTRACT HIV-affected families report higher rates of harmful alcohol use, intimate partner violence (IPV) and family conflict, which can have detrimental effects on children. Few evidence-based interventions exist to address these complex issues in Sub-Saharan Africa. This mixed methods study explores the potential of a family-based intervention to reduce IPV, family conflict and problems related to alcohol use to promote child mental health and family functioning within HIV-affected families in post-genocide Rwanda. A family home-visiting, evidence-based intervention designed to identify and enhance resilience and communication in families to promote mental health in children was adapted and developed for use in this context for families affected by caregiver HIV in Rwanda. The intervention was adapted and developed through a series of pilot study phases prior to being tested in open and randomized controlled trials (RCTs) in Rwanda for families affected by caregiver HIV. Quantitative and qualitative data from the RCT are explored here using a mixed methods approach to integrate findings. Reductions in alcohol use and IPV among caregivers are supported by qualitative reports of improved family functioning, lower levels of violence and problem drinking as well as improved child mental health, among the intervention group. This mixed methods analysis supports the potential of family-based interventions to reduce adverse caregiver behaviors as a major mechanism for improving child well-being. Further studies to examine these mechanisms in well-powered trials are needed to extend the evidence-base on the promise of family-based intervention for use in low- and middle-income countries.

    This article describes a program of prevention and intervention research conducted by the CHAMP (CHAMP – Collaborative HIV prevention and Adolescent Mental health Project; McKay & Paikoff, 2007) investigative team. CHAMP refers to a set of theory-driven, evidence-informed, collaboratively-designed, family-based approaches meant to address the prevention, health and mental health needs of poverty-impacted, African American and Latino urban youth who are either at risk for HIV exposure or who are perinatally-infected and at high risk for re-infection and possible transmission. CHAMP approaches are informed by theoretical frameworks that incorporate an understanding of the critical influences of multi-level contextual factors on youth risk taking and engagement in protective health behaviors. Highly influential theories include: the Triadic Theory of Influence (TTI) (Bell, Flay, & Paikoff, 2002), Social Action Theory (SAT) (Ewart, 1991) and Ecological Developmental Perspectives (Paikoff, Traube, & McKay, 2006). CHAMP program delivery strategies were developed via a highly collaborative process drawing upon community-based participatory research methods in order to enhance cultural and contextual sensitivity of program content and format. The development and preliminary outcomes associated with a family-based intervention for a new population, perinatally HIV-infected youth and their adult caregivers, referred to as CHAMP+, is described to illustrate the integration of theory, existing evidence and intensive input from consumers and healthcare providers.

    This study tested a family-based human immunodeficiency virus (HIV)/sexually transmitted infection (STI) prevention approach integrated within an empirically supported treatment for drug-involved young offenders, Multidimensional Family Therapy (MDFT). A randomized, controlled, two-site community-based trial was conducted with 154 youth and their parents. Drug-involved adolescents were recruited in detention, randomly assigned to either MDFT or Enhanced Services as Usual (ESAU), and assessed at intake, 3, 6, 9, 18, 24, 36, and 42-month follow-ups. Youth in both conditions received structured HIV/STI prevention in detention and those in MDFT also received family-based HIV/STI prevention as part of ongoing treatment following detention release. Youth in both conditions and sites significantly reduced rates of unprotected sex acts and STI incidence from intake to 9 months. They remained below baseline levels of STI incidence (10%) over the 42-month follow-up period. At Site A, adolescents who were sexually active at intake and received MDFT showed greater reduction in overall frequency of sexual acts and number of unprotected sexual acts than youth in ESAU between intake and 9-month follow-ups. These intervention differences were evident through the 42-month follow-up. Intervention effects were not found for STI incidence or unprotected sex acts at Site B. Intensive group-based and family intervention in detention and following release may reduce sexual risk among substance-involved young offenders, and a family-based approach may enhance effects among those at highest risk. Site differences in intervention effects, study limitations, clinical implications, and future research directions are discussed. PMID:26879671

    "No virus, no transmission." Studies have repeatedly shown that viral load (the quantity of virus present in blood and sexual secretions) is the strongest predictor of HIV transmission during unprotected sex or transmission from infected mother to child. Effective treatment lowers viral load to undetectable levels. If one could identify and treat all HIV-infected people immediately after infection, the HIV/AIDS epidemic would eventually disappear.Such a radical solution is currently unrealistic. In reality, not all people get tested, especially when they fear stigma and discrimination. Thus, not all HIV-infected individuals are known. Of those HIV-positive individuals for whom the diagnosis is known, not all of them have access to therapy, agree to be treated, or are taking therapy effectively. Some on effective treatment will stop, and in others, the development of resistance will lead to treatment failure. Furthermore, resources are limited: should we provide drugs to asymptomatic HIV-infected individuals without indication for treatment according to guidelines in order to prevent HIV transmission at the risk of diverting funding from sick patients in urgent need? In fact, the preventive potential of anti-HIV drugs is unknown. Modellers have tried to fill the gap, but models differ depending on assumptions that are strongly debated. Further, indications for antiretroviral treatments expand; in places like Vancouver and San Francisco, the majority of HIV-positive individuals are now under treatment, and the incidence of new HIV infections has recently fallen. However, correlation does not necessarily imply causation. Finally, studies in couples where one partner is HIV-infected also appear to show that treatment reduces the risk of transmission.More definite studies, where a number of communities are randomized to either receive the "test-and-treat" approach or continue as before, are now in evaluation by funding agencies. Repeated waves of testing would precisely

    Suicide is the second leading cause of death for youth aged 10-24. Research informed prevention efforts have the opportunity to decrease risk for suicidal ideation and behavior before it is manifested. Indeed, there is a small body of research findings demonstrating both proximal and distal effects of preventive interventions delivered in childhood and adolescence on suicidal ideation and/or behavior. These efforts build off of other secondary analyses of prevention research that has demonstrated benefits for multiple types of youth outcomes. This supplement provides "proof of concept" that family-based preventive interventions aimed at reducing a number of risk factors for suicide (e.g., substance use, externalizing, and internalizing behavior) can prevent suicidal ideation and behaviors.

    Adolescents and young people account for 40% of all new HIV infections each year, with South Africa one of the hardest hit countries, and having the largest population of people living with HIV. Although adolescent HIV prevention has been delivered through diverse modalities in South Africa, and although family-based approaches for adolescent HIV prevention have great potential for highly affected settings such as South Africa, there is a scarcity of empirically tested family-based adolescent HIV preventive interventions in this setting. We therefore conducted focus groups and in-depth interviews with key informants including clinicians, researchers, and other individuals representing organizations providing HIV and related health services to adolescents and parents (N = 82). We explored family perspectives and interactions around topics such as communication about sex, HIV, and relationships. Participants described aspects of family interactions that presented both challenges and opportunities for family-based adolescent HIV prevention. Parent-child communication on sexual topics were taboo, with these conversations perceived by some adults as an invitation for children to engage in HIV risk behavior. Parents experienced social sanctions for discussing sex and adolescents who asked about sex were often viewed as disrespectful and needing discipline. However, participants also identified context-appropriate strategies for addressing family challenges around HIV prevention including family meetings, communal parenting, building efficacy around parent-adolescent communication around sexual topics, and the need to strengthen family bonding and positive parenting. Findings indicate the need for a family intervention and identify strategies for development of family-based interventions for adolescent HIV prevention. These findings will inform design of a family intervention to be tested in a randomized pilot trial (ClinicalTrials.gov #NCT02432352). PMID:26916841

    Although the HIV incidence rate has slowed in some countries, HIV remains a serious health challenge, particularly in the developing world. The epidemic is increasingly feminised, with young women at high risk of acquiring the virus. There is thus a clear requirement for acceptable woman-initiated methods of HIV prevention. Foremost among these are vaginally-applied substances known as microbicides; early research into potential microbicides focussed on non-HIV-specific compounds such as surfactants and polyanionic entry inhibitors. However, proof of the microbicide concept as a viable prevention strategy was not provided until the CAPRISA 004 trial of a microbicide containing the HIV-specific antiretroviral tenofovir was completed in mid-2010. Confirmation of the proof of concept provided by CAPRISA 004 by at least two major trials will hopefully lead to licensure of the product by 2018. Parallel studies are planned to ascertain the feasibility of implementation of these products in the public sector with subsequent research focussed on appropriate and acceptable methods of delivery of the active ingredient, and to increase adherence through other delivery systems such as vaginal rings.

    Patterns of change on three intervention targets were examined in 151 families that participated in a family intervention designed to reduce and prevent children's aggressive behavior. Measures of parents' alliance and parenting skills and children's aggressive behavior were obtained at five times during the intervention. Three cluster analyses were conducted to identify patterns of change on each target. Linear and nonlinear patterns of improvement as well as two distinct patterns of no change were obtained. The patterns were differentiated by net improvement, overall level of skill, and trajectory of change. Family characteristics also differentiated the patterns and relations were found among patterns across intervention targets. The clinical implications of these findings are discussed. PMID:11314554

    An increasing number of adolescents born with HIV in South Africa are on antiretroviral treatment and have to confront complex issues related to coping with a chronic, stigmatizing and transmittable illness. Very few evidence-based mental health and health promotion programs for this population exist in South Africa. This study builds on a previous collaboratively designed and developmentally-timed family-based intervention for early adolescents (CHAMP). The study uses community-based participatory approach as part of formative research to evaluate a pilot randomized control trial at two hospitals. The paper reports on the development, feasibility and acceptability of the VUKA family-based program and its short-term impact on a range of psychosocial variables for HIV+ pre-adolescents and their caregivers. A ten session intervention of approximately 3 months duration was delivered to 65 pre-adolescents aged 10-13 years and their families. VUKA participants were noted to improve on all dimensions, including mental health, youth behaviour, HIV treatment knowledge, stigma, communication and adherence to medication. VUKA shows promise as a family-based mental and HIV prevention program for HIV+ pre-adolescents and which could be delivered by trained lay staff. PMID:23767772

    Although the number of new infections has declined recently, women still constitute almost half of the world's 34 million people with HIV infection, and HIV remains the leading cause of death among women of reproductive age. Prevention research has made considerable progress during the past few years in addressing the biological, behavioral and social factors that influence women's vulnerability to HIV infection. Nevertheless, substantial work still must be done in order to implement scientific advancements and to resolve the many questions that remain.

    In the decades since the emergence of HIV, numerous approaches to prevent transmission have been tested with varying degrees of success. Because a highly effective vaccine will not be available within the next decade, it is increasingly clear that preventing new HIV infections will require successful implementation of promising behavioral and biomedical interventions in combination. These prevention packages must be sufficiently flexible to include a variety of evidence-based interventions that serve each dynamic population they target, particularly those who are most vulnerable. To optimize the impact of combination intervention packages, well-designed implementation science studies are vital. Efficacy in a clinical trial does not necessarily translate to effectiveness at the population-level, and prioritized research studies should investigate programmatic implementation and operations scale-up and new methods to monitor and evaluate these processes both for organization and cost-effectiveness. With an estimated 2.7 million people becoming newly infected with HIV in 2010, the prevention of HIV remains an urgent global health priority. Since the emergence of HIV/AIDS more than 30 years ago, the evidence base for HIV prevention has expanded and evolved. Here we explore the status of evidence-based HIV prevention, describing both the continuing challenges and the emerging opportunities to reduce HIV incidence. PMID:22772385

    Purpose Cancer is a shared family experience and may provide a “teachable moment” to motivate at-risk family members to adopt cancer prevention and health promotion behaviors. This study explored how a diagnosis of colorectal cancer (CRC) is experienced by family members and may be used to develop a family-based CRC prevention program. Preferences regarding content, timing, and modes of program delivery were examined. Social cognitive theory provided the conceptual framework for the study. Methods This study employed mixed methodology (semi-structured interviews and self-report questionnaires). Participants included 73 adults (21 patients, 52 family members) from 23 families (two patients were deceased prior to being interviewed). Most patients (n=14; 67 %) were interviewed 1–5 years post-diagnosis. Individual interviews were audio-recorded, transcribed, and content analyzed. Results For many, a CRC diagnosis was described as a shared family experience. Family members supported each other’s efforts to prevent CRC through screening, exercising, and maintaining a healthy diet. Teachable moments for introducing a family-based program included the time of the patient’s initial cancer surgery and post-chemotherapy. Reported willingness to participate in a family-based program was associated with risk perception, self-efficacy, outcome expectancies, and the social/community context in which the program would be embedded. Program preferences included cancer screening, diet/nutrition, weight management, stress reduction, and exercise. Challenges included geographic dispersion, variation in education levels, generational differences, and scheduling. Conclusions CRC patients and family members are receptive to family-based programs. Feasibility concerns, which may be mitigated but not eliminated with technological advances, must be addressed for successful family-based programs. PMID:24728620

    HIV exceptionalism (and disease-specific programs generally) garner both unbalanced funding and the most talented personnel, distorting local health priorities. In support of HIV exceptionalism, the successful mobilization of significant global health sector resources was not possible prior to HIV. Both sides of the debate have merits; rather than perpetuating polarization, we suggest that sustained improvements in global health require creating a prevention infrastructure to meet multiple health challenges experienced by local communities. We propose four fundamental shifts in HIV and disease prevention: (1) horizontally integrating prevention at one site locally, with priorities tailored to local health challenges and managed by local community leaders; (2) using a family wellness metaphor for services, not disease prevention; (3) implementing evidence-based prevention programs (EBPP) based on common principles, factors, and processes, rather than replication of specific programs; and (4) utilizing the expertise of private enterprise to re-design EBPP into highly attractive, engaging, and accessible experiences.

    Rigorous testing of new HIV-prevention strategies is a time-consuming and expensive undertaking. Thus, making well informed decisions on which candidate-prevention approaches are most likely to provide the most benefit is critical to appropriately prioritizing clinical testing. In the case of biological interventions, the decision to test a given prevention approach in human trials rests largely on evidence of protection in preclinical studies. The ability of preclinical studies to predict efficacy in humans may depend on how well the model recapitulates key biological features of HIV transmission relevant to the question at hand. Here, we review our current understanding of the biology of HIV transmission based on data from animal models, cell culture, and viral sequence analysis from human infection. We summarize studies of the bottleneck in viral transmission; the characteristics of transmitted viruses; the establishment of infection; and the contribution of cell-free and cell-associated virus. We seek to highlight the implications of HIV-transmission biology for development of prevention interventions, and to discuss the limitations of existing preclinical models. PMID:26418086

    Microbicides represent a potential intervention strategy for preventing HIV transmission. Vaginal microbicides would meet the need for a discreet method that women could use to protect themselves against HIV. Although early-generation microbicides failed to demonstrate efficacy, newer candidates are based on more potent antiretroviral (ARV) products. Positive data from the CAPRISA 004 trial of tenofovir gel support use in women and represent a turning point for the field. This article reviews current progress in development of ARV-based microbicides. We discuss the consensus on selection criteria, the potential for drug resistance, rationale for drug combinations, and the use of pharmacokinetic (PK)/pharmacodynamic (PD) assessment in product development. The urgent need for continued progress in development of formulations for sustained delivery is emphasized. Finally, as the boundaries between different prevention technologies become increasingly blurred, consideration is given to the potential synergy of diverse approaches across the prevention landscape.

    2012-01-01

    Reducing the incidence of HIV remains one of our greatest public health challenges. However, there is growing optimism that preexposure prophylaxis (PrEP) could have a major impact on preventing incident HIV infection. Recently presented data on the use of oral PrEP in men who have sex with men (MSM) have provided proof-of-principle for this strategy. Additional clinical trials are evaluating whether PrEP provides similar protection to risk groups other than MSM, such as heterosexual persons and injection drug users. Still unanswered questions include optimal dosing strategies, long-term safety, maximizing adherence and minimizing costs, addressing drug resistance in the face of PrEP failure, optimizing access, and assessing effects on risk behavior. Future implementation will be guided by the results of clinical trials in progress. This article provides a review of the data on the potential strengths and limitations of PrEP as an HIV prevention strategy, identifies challenges to implementation of this approach, and outlines knowledge gaps.

    This exploratory study examines changes in suicidal ideation among a sample (N = 28) of homeless youth, ages 11-14, residing within family shelters in a large metropolitan area. Changes in suicidal ideation from pretest to posttest are compared across two group approaches to delivering HIV prevention. Youth and their families participating in the HOPE Family Program, incorporating a family strengthening approach, are compared to those receiving a traditional health education-only approach. Multivariate analyses reveal that youth in the HOPE Family Program were 13 times more likely to report a decrease of suicidal ideation. These findings indicate that health education programs integrating a family strengthening approach hold promise for positively impacting mental health outcomes for vulnerable youth. PMID:25157200

    Reliability and validity of intervention studies are impossible without adequate program fidelity, as it ensures that the intervention was implemented as designed and allows for accurate conclusions about effectiveness (Bellg AJ, Borrelli B, Resnick B et al. Enhancing treatment fidelity in health behavior change studies: best practices and recommendations from the NIH behavior change consortium. Health Psychol 2004; 23: 443–51). This study examines the relation between program fidelity with family engagement (i.e. satisfaction and participation) in family-based prevention programs for adolescent alcohol, tobacco or other drug use. Families (n = 381) were those with an 11- to 12-year-old child enrolled in Kaiser Permanente in the San Francisco area. Families participated in one of two programs: Strengthening Families Program: For Parents and Youth 10-14 (SFP) (Spoth R, Redmond C, Lepper H. Alcohol initiation outcomes of universal family-focused preventive interventions: one- and two-year follow-ups of a controlled study. J Stud Alcohol Suppl 1999; 13: 103–11) or Family Matters (FM) (Bauman KE, Ennett ST. On the importance of peer influence for adolescent drug use: commonly neglected considerations. Addiction 1996; 91: 185–98). Fidelity was assessed by: (i) adherence to the program manual and (ii) quality of implementation. No relationships were found for FM, a self-directed program. For SFP, higher quality scores were related to higher parent satisfaction. Higher adherence scores were related to higher satisfaction for youth, yet surprisingly to lower satisfaction for parents. Parent sessions involve much discussion, and to obtain high adherence scores, health educators were often required to limit this to implement all program activities. Findings highlight a delivery challenge in covering all activities while allowing parents to engage in mutually supportive behavior. PMID:20142414

    Standardized family-based interventions are the most effective way of preventing or treating adolescent substance abuse and delinquency. This paper first reviews the incidence of adolescent substance abuse worldwide emphasizing gender and causes by etiological risk and protective factors. New epigenetic research is included suggesting that nurturing parenting significantly prevents the phenotypic expression of inherited genetic diseases including substance abuse. Evidence-based family interventions are reviewed including family change theories behind their success, principles and types of family-based interventions, research results, cultural adaptation steps for ethnic and international translation, and dissemination issues. The author's Strengthening Family Program is used as an example of how these principles of effective prevention and cultural adaptation can result in highly effective prevention programs not only for substance abuse, but for other impulse control disorders as well. The conclusions include recommendations for more use of computer technologies to cut the high cost of family interventions relative to youth-only prevention programs and increase the public health impact of evidence-based prevention programs. The paper recommends that to reduce health care costs these family-based approaches should be applied to the prevention and treatment of other impulse control disorders such as obesity and type 2 diabetes, sexually transmitted diseases, and delinquency.

    2014-06-01

    Expansions in health care coverage, a comprehensive framework for HIV prevention and care, electronic medical records, and novel HIV prevention modalities create a current opportunity to change the trajectory of the HIV epidemic in the United States. HIV is increasingly disproportionately found in populations historically at higher risk, including gay men and other men who have sex with men, transgender women, injection drug users, and persons of color. This underscores the need for providers to identify persons at higher risk for HIV and assure the provision of screening and prevention services. In turn, universal screening for HIV-testing every adolescent and adult at least once in their lifetime-will increasingly be necessary to find the infrequent cases of HIV in lower risk populations. In both these domains, primary care providers will play a unique role in complementing traditional providers of HIV prevention and care services by increasing the proportion of their patients who have been screened for HIV, opening dialogues around sexual health, including asking about sexual orientation and gender identity, and prescribing antivirals as pre- and postexposure prophylaxis for their non-HIV-infected patients. Primary care providers must understand and embrace their importance along the HIV prevention and care continuum. PMID:26789615

    Serodiscordant couples play an important role in maintaining the global HIV epidemic. This review summarizes biobehavioral and biomedical HIV prevention options for serodiscordant couples focusing on advances in 2013 and 2014, including World Health Organization guidelines and best-evidence for couples counseling, couples-based interventions, and the use of antiviral agents for prevention. In the past few years marked advances have been made in HIV prevention for serodiscordant couples and numerous ongoing studies are continuously expanding HIV prevention tools, especially in the area of pre-exposure prophylaxis. Uptake and adherence to antiviral therapy remains a key challenge. Additional research is needed to develop evidence-based interventions for couples, and especially for male-male couples. Randomized trials have demonstrated the prevention benefits of antiretroviral-based approaches among serodiscordant couples; however, residual transmission observed in recognized serodiscordant couples represents an important and resolvable challenge in HIV prevention.

    Purpose of review Young women in sub-Saharan Africa bear a disproportionate HIV burden. They urgently require new HIV prevention approaches that women can use. This review provides an overview of the use of antiretrovirals for HIV pre-exposure prophylaxis (PrEP), highlighting some of the challenges with this technology and explores the potential role of monoclonal antibodies (mAbs) for HIV prevention in women. Recent findings Recent findings on the initial steps in viral entry and establishment of a productive local infectious nidus in the vaginal epithelium has provided important clues for HIV prevention in the female genital tract. Topical and oral formulations of antiretroviral drugs have been shown to prevent HIV infection in women with varying levels of success, depending principally on adherence. Further, a number of new broad and potent mAbs have been isolated over the last 5 years. Non-human primate studies demonstrate that broadly neutralizing HIV mAbs can protect rhesus macaques from SHIV infection. These findings have created newfound enthusiasm for passive immunization as a potential prevention strategy for women. Summary If potent broadly neutralising mAbs are effective in preventing HIV infection in women, it could fill an important gap in HIV prevention technologies for young women, especially in Africa.

    The controversy over "targeted" versus "universalistic" programs for HIV prevention has persisted throughout the history of the HIV/AIDS epidemic in the United States and in some European countries. Building on previous analyses, we outline methods for integrating universalistic and targeted HIV prevention programming. The outline considers possible synergy between targeted and universalistic programs, rather than a forced choice between the two. Components within this framework include a continuum of the intensity of targeted programs, specification of local risk behavior populations, categories of risk behavior, and HIV seroprevalence within local risk-behavior populations. Given the scarce resources currently available, preventing all new HIV infections is not a realistic public health goal, but with better use of current scientific knowledge, it should be possible to greatly reduce the rate of new HIV infections.

    Recommendations for HIV prevention in clinical care settings by an IAS-USA panel were recently published. They include recommendations on HIV testing, antiretroviral therapy initiation, risk-reduction counseling, and antiretroviral therapy adherence counseling for HIV-infected individuals. For individuals at risk for HIV infection, recommendations for preexposure prophylaxis, other risk-reduction strategies, adherence counseling, and postexposure prophylaxis are included. Many HIV-infected individuals in the United States are not fully engaged in HIV care and are not virologically suppressed, thus a crucial component of efforts to reduce HIV transmission is moving patients through the HIV care continuum.

Recent findings A randomized, clinical trial demonstrated that antiretroviral therapy reduces the sexual transmission of HIV in HIV-serodiscordant couples by more than 96%. The logistical challenges in preparing for and conducting such a trial were considerable. Summary HPTN 052 required many years of preparation, considerable collaboration between National Institute of Health and six pharmaceutical companies, and careful ongoing consideration of a large number of ethical issues. HPTN 052 revealed the magnitude of benefit when using antiretroviral therapy to prevent the transmission of HIV, and served as proof of a concept.

    Although research has documented the positive effects of family-based prevention programs, the field lacks specific information regarding why these programs are effective. The current study summarized the effects of family-based programs on adolescent substance use using a component-based approach to meta-analysis in which we decomposed programs into a set of key topics or components that were specifically addressed by program curricula (e.g., parental monitoring/behavior management,problem solving, positive family relations, etc.). Components were coded according to the amount of time spent on program services that targeted youth, parents, and the whole family; we also coded effect sizes across studies for each substance-related outcome. Given the nested nature of the data, we used hierarchical linear modeling to link program components (Level 2) with effect sizes (Level 1). The overall effect size across programs was .31, which did not differ by type of substance. Youth-focused components designed to encourage more positive family relationships and a positive orientation toward the future emerged as key factors predicting larger than average effect sizes. Our results suggest that, within the universe of family-based prevention, where components such as parental monitoring/behavior management are almost universal, adding or expanding certain youth-focused components may be able to enhance program efficacy.

    BACKGROUND: The majority of knowledge related to implementation of family-based substance use prevention programs is based on programs delivered in school and community settings. The aim of this study is to examine procedures related to implementation effectiveness and quality of two family-based universal substance use prevention programs delivered in health care settings, the Strengthening Families Program: For Parents and Youth 10-14 (SFP) and Family Matters (FM). These evidence-based programs were delivered as part of a larger random control intervention study designed to assess the influence of program choice vs. assignment on study participation and adolescent substance use outcomes. We also assess the effects of program choice (vs. assignment to program) on program delivery. METHODS: A mixed method case study was conducted to assess procedures used to maximize implementation quality and fidelity of family-based prevention programs delivered in health care settings. Families with an 11 year old child were randomly selected for study participation from health plan membership databases of 4 large urban medical centers in the San Francisco Bay Area. Eligible families were initially randomized to a Choice study condition (families choose SFP or FM) or Assigned study condition (assigned to FM, SFP or control group); 494 ethnically diverse families were selected for participation in study programs. RESULTS: Successful implementation of family prevention programs in health care settings required knowledge of the health care environment and familiarity with established procedures for developing ongoing support and collaboration. Ongoing training of program deliverers utilizing data from fidelity assessment appeared to contribute to improved program fidelity over the course of the study. Families who chose FM completed the program in a shorter period (p<.0001) and spent more time implementing program activities (p=0.02) compared to families assigned to FM. SFP "choice

    2012-01-01

    The impressive advances in antiretroviral (ARV) therapy of chronic human immunodeficiency virus (HIV) infections during the last decade and the availability of potent ARV drugs have fueled interest in using chemoprophylaxis as a novel HIV prevention strategy. Preexposure prophylaxis (PrEP) refers to the use of ARV drugs in HIV-negative persons to prevent HIV infection. The rationale for PrEP builds on the success of ARV prophylaxis in preventing mother-to-child transmission of HIV and on a large body of animal studies that show the efficacy of PrEP against mucosal and parenteral infection. We focus on oral administration of ARV drugs for prevention of HIV infection. Identifying an effective prophylactic pill that individuals can take outside the setting of sexual intercourse precludes the necessity to disclose such use to their partners, thereby empowering those who might not be in a position to negotiate with their partners. Several human clinical trials evaluating the efficacy of daily regimens of the HIV reverse-transcriptase (RT) inhibitors tenofovir disoproxil fumarate (TDF) or Truvada (TDF and emtricitabine [FTC]) are under way among high-risk populations. The results of one trial among men who have sex with men showed that daily Truvada was safe and effective, providing the first support for oral PrEP as a prevention strategy. Here we outline the preclinical and clinical research on oral PrEP, pharmacologic considerations, and future directions and challenges. PMID:22393535

    1999-01-01

    This article features intravaginal microbicides available in various forms, such as gel, suppository, cream, film or sponge, preventing HIV infections and other sexually transmitted disease (STD) pathogens. Microbicides also vary in their action by boosting the body's natural defense, by killing or inactivating STD pathogens, or by creating a protective barrier between the virus and the vaginal wall. Despite the potential of these products to prevent HIV and other STDs, large pharmaceutical companies are hesitant to invest in them because they assume that the only market would be in the developing world. The Global Campaign for Microbicides and HIV/STD Prevention Alternatives for Women was launched having the priority goal of educating individuals about female condoms and microbicides as promising technologies that deserve more attention and investment. While microbicides are not available yet, the use of condom still provides the best protection against HIV/STDs. PMID:12295464

  19. Microbicides: a new hope for HIV prevention

    Human immunodeficiency virus (HIV), causative agent of acquired immunodeficiency syndrome (AIDS), is a global health concern. To control its transmission, safe sex has been proposed as one of the strategies. Microbicides- intravaginal/intrarectal topical formulations of anti-HIV agents have also been proposed to prevent HIV transmission. Microbicides would provide protection by directly inactivating HIV or preventing the attachment, entry or replication of HIV in susceptible target cells as well as their dissemination from target cells present in semen or the host cells lining the vaginal/rectal wall to other migratory cells. Microbicides must be safe, effective following vaginal or rectal administration, and should cause minimal or no genital symptoms or inflammations following long-term repeated usage. However, a safe and efficacious anti-HIV microbicide is not yet available despite the fact that more than 60 candidate agents have been identified to have in vitro activity against HIV, several of which have advanced to clinical testing. Nonetheless, proof-of-concept of microbicides has been established based on the results of recent CAPRISA 004 clinical trials. In this article, the trends and challenges in the development of effective and safe microbicides to combat HIV transmission are reviewed. PMID:22310826

    Although clinical experience and preliminary research suggest that some transgender people are at significant risk for HIV, this stigmatized group has so far been largely ignored in HIV prevention. As part of the development of HIV prevention education targeting the transgender population, focus groups of selected transgender individuals assessed their HIV risks and prevention needs. Data were gathered in the following four areas: (1) the impact of HIV/AIDS on transgender persons; (2) risk factors; (3) information and services needed; and (4) recruitment strategies. Findings indicated that HIV/AIDS compounds stigmatization related to transgender identity, interferes with sexual experimentation during the transgender 'coming out' process, and may interfere with obtaining sex reassignment. Identified transgender-specific risk factors include: sexual identity conflict, shame and isolation, secrecy, search for affirmation, compulsive sexual behaviour, prostitution, and sharing needles while injecting hormones. Community involvement, peer education and affirmation of transgender identity were stressed as integral components of a successful intervention. Education of health professionals about transgender identity and sexuality and support groups for transgender people with HIV/AIDS are urgently needed. PMID:9828969

    Current ideas about HIV prevention include a mixture of primarily biomedical interventions, socio-mechanical interventions such as sterile syringe and condom distribution, and behavioral interventions. This article presents a framework for socially-integrated transdisciplinary HIV prevention that may improve current prevention efforts. It first describes one socially-integrated transdisciplinary intervention project, the Transmission Reduction Intervention Project. We focus on how social aspects of the intervention integrate its component parts across disciplines and processes at different levels of analysis. We then present socially-integrated perspectives about how to improve combination antiretroviral treatment (cART) processes at the population level in order to solve the problems of the treatment cascade and make "treatment as prevention" more effective. Finally, we discuss some remaining problems and issues in such a social transdisciplinary intervention in the hope that other researchers and public health agents will develop additional socially-integrated interventions for HIV and other diseases.

    Background There is a huge interest by faith-based organizations (FBOs) in sub-Saharan Africa and elsewhere in HIV prevention interventions that build on the religious aspects of being. Successful partnerships between the public health services and FBOs will require a better understanding of the conceptual framing of HIV prevention by FBOS to access for prevention intervention, those concepts the churches of various denominations and their members would support or endorse. This study investigated the conceptual framing of HIV prevention among church youths in Botswana; - a country with one of the highest HIV prevalence in the world. Method Participants were 213 Pentecostal church members (67% female; age range 12 to 23 years; median age = 19 years). We engaged the participants in a mixed-method inductive process to collect data on their implicit framing of HIV prevention concepts, taking into account the centrality of religion concepts to them and the moderating influences of age, gender and sexual experience. After, we analysed the data using multi-dimensional scaling (MDS) and hierarchical cluster analysis (HCA) to map the ways the church youths framed HIV prevention. Results The findings suggest the church youth to conceptually frame their HIV prevention from both faith-oriented and secular-oriented perspectives, while prioritizing the faith-oriented concepts based on biblical teachings and future focus. In their secular-oriented framing of HIV prevention, the church youths endorsed the importance to learn the facts about HIV and AIDS, understanding of community norms that increased risk for HIV and prevention education. However, components of secular-oriented framing of HIV prevention concepts were comparatively less was well differentiated among the youths than with faith-oriented framing, suggesting latent influences of the church knowledge environment to undervalue secular oriented concepts.

    We assessed attitudes to medicines, HIV treatments and antiretroviral-based prevention in a national, online survey of 1,041 Australian gay men (88.3% HIV-negative and 11.7% HIV-positive). Multivariate analysis of variance was used to identify the effect of HIV status on attitudes. HIV-negative men disagreed with the idea that HIV drugs should be restricted to HIV-positive people. HIV-positive men agreed and HIV-negative men disagreed that taking HIV treatments was straightforward and HIV-negative men were more sceptical about whether HIV treatment or an undetectable viral load prevented HIV transmission. HIV-negative and HIV-positive men had similar attitudes to pre-exposure prophylaxis but divergent views about 'treatment as prevention'. PMID:23001412

    Cash payments to improve health outcomes have been used for many years, however, their use for HIV prevention is new and the impact not yet well understood. We provide a brief background on the rationale behind using cash to improve health outcomes, review current studies completed or underway using cash for prevention of sexual transmission of HIV, and outline some key considerations on the use of cash payments to prevent HIV infections. We searched the literature for studies that implemented cash transfer programs and measured HIV or HIV-related outcomes. We identified 16 studies meeting our criteria; 10 are completed. The majority of studies have been conducted with adolescents in developing countries and payments are focused on addressing structural risk factors such as poverty. Most have seen reductions in sexual behavior and one large trial has documented a difference in HIV prevalence between young women getting cash transfers and those not. Cash transfer programs focused on changing risky sexual behaviors to reduce HIV risk suggest promise. The context in which programs are situated, the purpose of the cash transfer, and the population will all affect the impact of such programs; ongoing RCTs with HIV incidence endpoints will shed more light on the efficacy of cash payments as strategy for HIV prevention.

    2010-10-01

    Evidence-informed and human rights-based combination prevention combines behavioural, biomedical, and structural interventions to address both the immediate risks and underlying causes of vulnerability to HIV infection, and the pathways that link them. Because these are context-specific, no single prescription or standard package will apply universally. Anchored in 'know your epidemic' estimates of where the next 1000 infections will occur and 'know your response' analyses of resource allocation and programming gaps, combination prevention strategies seek to realign programme priorities for maximum effect to reduce epidemic reproductive rates at local, regional, and national levels. Effective prevention means tailoring programmes to local epidemics and ensuring that components are delivered with the intensity, quality, and scale necessary to achieve intended effects. Structural interventions, addressing the social, economic, cultural, and legal constraints that create HIV risk environments and undermine the agency of individuals to protect themselves and others, are also public goods in their own right. Applying the principles of combination prevention systematically and consistently in HIV programme planning, with due attention to context, can increase HIV programme effectiveness. Better outcome and impact measurement using multiple methods and data triangulation can build the evidence base on synergies between the components of combination prevention at individual, group, and societal levels, facilitating iterative knowledge translation within and among programmes.

    Asian Americans have been largely ignored in the prevention outcome literature. In this study, we tested a parent-child program with a sample of Asian American adolescent girls and their mothers, and evaluated the program's efficacy on decreasing girls' substance use and modifying risk and protective factors at individual, family, and peer levels. A total of 108 Asian American mother-daughter dyads recruited through online advertisements and from community service agencies were randomly assigned to an intervention arm (n = 56) or to a test-only control arm (n = 52). The intervention consisted of a nine-session substance abuse prevention program, delivered entirely online. Guided by family interaction theory, the prevention program aimed to strengthen the quality of girls' relationships with their mothers while increasing girls' resilience to resist substance use. Intent-to-treat analyses showed that at 2-year follow-up, intervention-arm dyads had significantly higher levels of mother-daughter closeness, mother-daughter communication, maternal monitoring, and family rules against substance use compared with the control-arm dyads. Intervention-arm girls also showed sustained improvement in self-efficacy and refusal skills and had lower intentions to use substances in the future. Most important, intervention-arm girls reported fewer instances of alcohol and marijuana use and prescription drug misuse relative to the control-arm girls. The study suggests that a culturally generic, family-based prevention program was efficacious in enhancing parent-child relationships, improving girls' resiliency, and preventing substance use behaviors among Asian American girls.

    2016-07-01

    Although the number of new HIV infections has declined by over 30% in the past decade, the number of people who acquire HIV each year remains unacceptably high. In 2014 the Joint United Nations Programme on HIV/AIDS (UNAIDS) estimated that there were about 2 million new HIV infections. The virus continues to spread, particularly in key populations, such as men who have sex with men (MSM), transgender individuals, sex workers and people who inject drugs. In Africa, young women have the highest HIV incidence rates. Scaling up known efficacious HIV prevention strategies for these groups at high risk is therefore a high priority. HIV prevention has generally been targeted at HIV-negative individuals or in some instances, entire communities. Prevention efforts are, however, shifting from a narrow focus on HIV-uninfected persons to a continuum of prevention that includes both HIV-negative and HIV-positive individuals. Given that a single HIV prevention intervention is unlikely to be able to alter the epidemic trajectory as HIV epidemics in communities are complex and comprise a mosaic of different risk factors and different routes of transmission, there is need to provide combination prevention. Hence, a mix of behavioural, biomedical and structural HIV prevention options is likely to be needed to alter the course of the HIV epidemic. The combination of HIV prevention interventions needed will vary depending on cultural context, the population targeted and the stage of the epidemic. This paper reviews the available HIV prevention strategies for young women and discusses new HIV prevention approaches in development. PMID:27399041

    Young, Ingrid; Flowers, Paul; McDaid, Lisa

    2016-03-01

    This article examines how biomedicalisation is encountered, responded to and negotiated within and in relation to new biomedical forms of HIV prevention. We draw on exploratory focus group discussions on pre-exposure prophylaxis (PrEP) and treatment as prevention (TasP) to examine how the processes of biomedicalisation are affected by and affect the diverse experiences of communities who have been epidemiologically framed as 'vulnerable' to HIV and towards whom PrEP and TasP will most likely be targeted. We found that participants were largely critical of the perceived commodification of HIV prevention as seen through PrEP, although this was in tension with the construction of being medical consumers by potential PrEP candidates. We also found how deeply entrenched forms of HIV stigma and homophobia can shape and obfuscate the consumption and management of HIV-related knowledge. Finally, we found that rather than seeing TasP or PrEP as 'liberating' through reduced levels of infectiousness or risk of transmission, social and legal requirements of responsibility in relation to HIV risk reinforced unequal forms of biomedical self-governance. Overall, we found that the stratifying processes of biomedicalisation will have significant implications in how TasP, PrEP and HIV prevention more generally are negotiated. PMID:26498141

    The prevention of the HIV infection remains relevant considering the dynamics of the epidemic and the slackening of the preventive behavior of certain populations. The strategies associate initiatives of universal prevention: information, education, communication, screening; and specific actions in the direction of the most exposed populations. The paradigms of prevention evolved a lot these last years to take into account the preventive efficiency of antiretrovirals. If the condom remains the reference method, it is advisable for the populations the most exposed today to associate all the tools of prevention: behavioral methods, screening and antiretroviral. The possibility given to non-governmental organizations to realize test of fast screening allowed to go to closer of the most exposed populations.The arrival on the market of the autotests must be supervised to touch the people who do not turn to the screening.

    Historically, interventions to prevent STD/HIV transmission have been categorized by program methodology rather than defining the content and nature of the intervention. A new taxonomy is needed to help expand the scope of interventions that can be used to prevent STD and HIV transmission. The taxonomy defines two major types of interventions, individual-level and structural level. The former targets risk factors attributable to individuals. Structural interventions target conditions outside the control of the individual. Individual-level interventions focus on counseling, screening, and treatment. They include psychological and biological interventions. Structural-level interventions address accessibility of relevant consumer products (condoms, needles), physical structures (e.g. blighted and abandoned housing, lighting, design of social facilities), social structures (policies that facilitate or constrain behaviors such as supervision of youth, and enforcement of alcohol beverage laws); and media messages (messages and images in the broadcast and print media that portray high-risk behaviors as positive and without serious consequences). A new taxonomy not only clarifies the content of preventive interventions but highlights neglected strategies involving individual biological interventions and structural interventions to prevent STD/HIV transmission.

    Southeastern states are among the hardest hit by the HIV epidemic in this country, and racial disparities in HIV rates are high in this region. This is particularly true in our communities of interest in rural eastern North Carolina. Although most recent efforts to prevent HIV attempt to address multiple contributing factors, we have found few multilevel HIV interventions that have been developed, tailored or tested in rural communities for African Americans. We describe how Project GRACE integrated Intervention Mapping (IM) methodology with community based participatory research (CBPR) principles to develop a multi-level, multi-generational HIV prevention intervention. IM was carried out in a series of steps from review of relevant data through producing program components. Through the IM process, all collaborators agreed that we needed a family-based intervention involving youth and their caregivers. We found that the structured approach of IM can be adapted to incorporate the principles of CBPR. PMID:20528128

    2008-01-01

    Background Only four out of 31 completed randomized controlled trials (RCTs) of HIV prevention strategies against sexual transmission have shown significant efficacy. Poor adherence may have contributed to the lack of effect in some of these trials. In this paper we explore the impact of various levels of adherence on measured efficacy within an RCT. Analysis We used simple quantitative methods to illustrate the impact of various levels of adherence on measured efficacy by assuming a uniform population in terms of sexual behavior and the binomial model for the transmission probability per partnership. At 100% adherence the measured efficacy within an RCT is a reasonable approximation of the true biological efficacy. However, as adherence levels fall, the efficacy measured within a trial substantially under-estimates the true biological efficacy. For example, at 60% adherence, the measured efficacy can be less than half of the true biological efficacy. Conclusion Poor adherence during a trial can substantially reduce the power to detect an effect, and improved methods of achieving and maintaining high adherence within trials are needed. There are currently 12 ongoing HIV prevention trials, all but one of which require ongoing user-adherence. Attention must be given to methods of maximizing adherence when piloting and designing RCTs and HIV prevention programmes. PMID:18620578

    Abstract The Chinese national observational cohort study suggests that the treatment-as-prevention (TasP) approach can be an effective public health HIV-1 prevention strategy. However, results from that study may have been biased because the follow-up time of index patients prior to their initiation of antiretroviral therapy (ART) was excluded. In this study, we correct for such bias by using an extended time-dependent Cox regression model to conduct a cohort study analysis of serodiscordant couples in Guangxi of China, inclusive of all follow-up time. During the follow-up of this observational cohort study of HIV-1 sero-discordant couples, the positive index partners may have never be treated with ART, or enter untreated but subsequently began treatment, or may have been treated immediately upon entry into the public health system. The treatment effectiveness of ART in HIV-1 acquisition among HIV-negative partners is assessed by the extended Cox regression model with treatment status as a time-varying covariate. A total of 6548 sero-discordant couples were included in the cohort study analysis. Among them, 348 negative partners sero-converted. HIV seroincidence was significantly higher among the nontreated (4.3 per 100 person-years, 3.7–4.9) compared with those receiving ART (1.8 per 100 person-years, 1.5–2.0). An overall 35% reduction in risk of HIV transmission was associated with receiving ART (adjusted hazard ratio [AHR] 0.65, 95% confidence interval [CI] 0.51–0.83), and the yearly risk reduction was also significant in the first 3 consecutive years of follow-up. Moreover, ART was found to be significantly inversely associated with multiple baseline characteristics of index partners. TasP may be feasible on a national or regional scale. In addition to other proven preventive strategies such as the use of condoms, ART adherence to maintain viral suppression would then be the key challenge for successful TasP implementation.

    Over the past decade, the global response to the HIV epidemic has been unprecedented, and enormous progress has been made. Significant investment in the roll out of antiretroviral treatment (ART) and efforts to increase treatment coverage have greatly reduced the number of AIDS-related deaths worldwide. There are a growing number of promising innovations to expand the HIV prevention mix. However, the reach of these interventions is still very limited in adolescent girls and young women (15-24 years) and the full realisation of the intervention mandates has not yet been achieved. The HIV prevention field has been criticised for the tendency to adopt a narrow focus. The Fast-Track Strategy offers a unique opportunity for the HIV prevention field to broaden its gaze and to begin to identify synergies (and efficiencies) with prevention approaches from other global development priorities, namely sexual and reproductive health and rights (SRHR). This paper applies a SRHR lens to HIV prevention by highlighting the critical relationship between unintended pregnancy and HIV, and seeks to expand on earlier debates that prevention of HIV and prevention of unintended pregnancy are inextricably linked, complementary activities with interrelated and common goals. We call for the prioritisation of prevention of unintended pregnancy amongst two overlapping population groups - girls and young women (15-24 years old) and women living with HIV - as a key tactic to accomplish the Joint United Nations Programme on HIV/AIDS (UNAIDS) Fast-Track Strategy and as a way to fully realise existing HIV prevention efforts. We discuss the intersecting pathways between HIV prevention and unintended pregnancy prevention and build a case for contraception to be placed at the centre of the HIV prevention agenda.

    As antiretroviral treatment of HIV infection has become increasingly accessible, attention has focused on whether these drugs can used for prevention because of increased tolerability of newer medications, decreased cost, and the limitations of other approaches. We review the status of antiretroviral HIV prevention, including chemoprophylaxis, as well as the effects of treatment of infected individuals on prevention. It is possible that the life-saving agents that have transformed the natural history of AIDS can be a critical component of HIV prevention efforts, but their ultimate role in affecting HIV transmission dynamics remains to be defined.

  3. Preventing HIV infection: educating the general public.

    PubMed

    Kroger, F

    1991-01-01

    This essay discusses the rationale for targeting HIV prevention programs to the general public, as opposed to focusing strictly on high-risk populations. The author first considers varying definitions of the term "general public," then explains the goal of general public education programs. Additionally, the author lays down the theoretical foundations of general audience education programs and weights related research findings. Finally, he offers recommendations for future practice. Noting the complex socioecological elements involved in health behavior, the author argues in favor of a broad definition for the general public. This broad outlook allows programs to still target high-risk population while not bypassing low-risk persons, who are sometimes treated as irrelevant because they do not contribute to excess morbidity or mortality. When it comes to HIV educational programs for the general public, their goals should be to instruct the public on how the virus is transmitted, to allay unfounded fears, and to increase the level of support for AIDS prevention and control. Such a program would require a theoretical basis drawn from multiple sources: health education, health communication, clinical and social psychology, and social marketing. The author concludes by proving recommendations designed to reinforce existing programs: 1) strengthen efforts to ensure that all people are educated about HIV and to encourage people to treat AIDS patients with compassion; 2) continue to explore for the most effective communication channels; 3) strengthen the communication infrastructure for those who are disenfranchised from health education; and 4) strengthen evaluation efforts of health communication programs.

    This article describes an adolescent, peer-education training program in Jamaica that was developed and operated by the Red Cross Societies of Jamaica and the US and was funded by AIDSCAP. The program aimed to develop a training system to prepare youth peer educators in preventing the spread of HIV infections and sexually transmitted diseases. The goal was to increase knowledge about, change attitudes toward, and develop prevention skills for HIV/AIDS. The initial program was to be replicated on a large scale and be sustainable over time. The program was developed in response to the 1500+ Jamaicans diagnosed with AIDS and the 20,000 or so with HIV infections. Transmission is mostly heterosexual. 15% of girls and 47% of boys are sexually active by 14 years of age, and almost 50% of syphilis and gonorrhea cases are among adolescents. The national training program relies on peer educators, aged 14-19 years, who are literate to the 6th-grade level. Training sessions are conducted for 10-21 persons/session for 27 hours over 3 weekends. Training relies on engaging games and activities. Trainees are taught how to facilitate 14 specific activities, including the correct way to use a condom. Peer educators work together in groups of twos or threes among groups of 10-15 adolescents, aged 10-15 years. By the third year of operation, most of the systems and materials were in place and the program expanded; cost-benefit analysis revealed that costs were returned. The program has continued with a variety of funds and delivery systems and new funding will likely shift the program emphasis. The program has survived with the enthusiasm and support of the trainers. Other start-up programs should ensure the involvement of youth at all stages of development. PMID:12293325

    Background: Women and adolescent girls bear a significant burden of the global HIV pandemic. Both behavioral and biomedical prevention approaches have been shown to be effective. In order to foster the most effective combination HIV-prevention approaches for women and girls, it is imperative to understand the unique biological, social, and structural considerations that increase vulnerability to acquiring HIV within this population. Primary Study Objective: The purpose of this article is to propose novel ideas for personalized biobehavioral HIV prevention for women and adolescent girls. The central argument is that we must transcend unilevel solutions for HIV prevention toward comprehensive, multilevel combination HIV prevention packages to actualize personalized biobehavioral HIV prevention. Our hope is to foster transnational dialogue among researchers, practitioners, educators, and policy makers toward the actualization of the proposed recommendations. Methods: We present a commentary organized to review biological, social, and structural factors that increase vulnerability to HIV acquisition among women and adolescent girls. The overview is followed by recommendations to curb HIV rates in the target population in a sustainable manner. Results: The physiology of the lower female reproductive system biologically increases HIV risk among women and girls. Social (eg, intimate partner violence) and structural (eg, gender inequality) factors exacerbate this risk by increasing the likelihood of viral exposure. Our recommendations for personalized biobehavioral HIV prevention are to (1) create innovative mechanisms for personalized HIV risk—reduction assessments; (2) develop mathematical models of local epidemics; (3) prepare personalized, evidence-based combination HIV risk—reduction packages; (4) structure gender equity into society; and (5) eliminate violence (both physical and structural) against women and girls. Conclusions: Generalized programs and

    Validated data regarding HIV-transmission in prisons in developing countries is scarce. We examined sexual and injecting drug use behavior and HIV and HCV transmission in an Indonesian narcotic prison during the implementation of an HIV prevention and treatment program during 2004-2007 when the Banceuy Narcotic Prison in Indonesia conducted an HIV transmission prevention program to provide 1) HIV education, 2) voluntary HIV testing and counseling, 3) condom supply, 4) prevention of rape and sexual violence, 5) antiretroviral treatment for HIV-positive prisoners and 6) methadone maintenance treatment. During a first survey that was conducted between 2007 and 2009, new prisoners entered Banceuy Narcotics Prison were voluntary tested for HIV and HCV-infection after written informed consent was obtained. Information regarding sexual and injecting risk behavior and physical status were also recorded at admission to the prison. Participants who tested negative for both HIV and HCV during the first survey were included in a second survey conducted during 2008-2011. During both surveys, data on mortality among HIV-seropositive patients were also recorded. All HIV-seropositive participants receive treatment for HIV. HIV/ AIDS-related deaths decreased: 43% in 2006, 18% in 2007, 9% in 2008 and 0% in 2009. No HIV and HCV seroconversion inside Banceuy Narcotic Prison were found after a median of 23 months imprisonment (maximum follow-up: 38 months). Total of 484.8 person-years observation was done. Participants reported HIV transmission risk-behavior in Banceuy Prison during the second survey was low. After implementation of HIV prevention and treatment program, no new HIV or HCV cases were detected and HIV-related mortality decreased. PMID:26863859

  13. Highly active antiretroviral treatment for the prevention of HIV transmission

    PubMed Central

    2010-01-01

    In 2007 an estimated 33 million people were living with HIV; 67% resided in sub-Saharan Africa, with 35% in eight countries alone. In 2007, there were about 1.4 million HIV-positive tuberculosis cases. Globally, approximately 4 million people had been given highly active antiretroviral therapy (HAART) by the end of 2008, but in 2007, an estimated 6.7 million were still in need of HAART and 2.7 million more became infected with HIV. Although there has been unprecedented investment in confronting HIV/AIDS - the Joint United Nations Programme on HIV/AIDS estimates $13.8 billion was spent in 2008 - a key challenge is how to address the HIV/AIDS epidemic given limited and potentially shrinking resources. Economic disparities may further exacerbate human rights issues and widen the increasingly divergent approaches to HIV prevention, care and treatment. HIV transmission only occurs from people with HIV, and viral load is the single greatest risk factor for all modes of transmission. HAART can lower viral load to nearly undetectable levels. Prevention of mother to child transmission offers proof of the concept of HAART interrupting transmission, and observational studies and previous modelling work support using HAART for prevention. Although knowing one's HIV status is key for prevention efforts, it is not known with certainty when to start HAART. Building on previous modelling work, we used an HIV/AIDS epidemic of South African intensity to explore the impact of testing all adults annually and starting persons on HAART immediately after they are diagnosed as HIV positive. This theoretical strategy would reduce annual HIV incidence and mortality to less than one case per 1000 people within 10 years and it would reduce the prevalence of HIV to less than 1% within 50 years. To explore HAART as a prevention strategy, we recommend further discussions to explore human rights and ethical considerations, clarify research priorities and review feasibility and acceptability

    Antiviral agents can be used to prevent HIV transmission before exposure as preexpo-sure prophylaxis (PrEP), after exposure as postexposure prophylaxis, and as treatment of infected people for secondary prevention. Considerable research has shed new light on antiviral agents for PrEP and for prevention of secondary HIV transmission. While promising results have emerged from several PrEP trials, the challenges of poor adherence among HIV-negative clients and possible increase in sexual risk behaviors remain a concern. In addition, a broader pipeline of antiviral agents for PrEP that focuses on genital tract pharmacology and safety and resistance issues must be developed. Antiretroviral drugs have also been used to prevent HIV transmission from HIV-infected patients to their HIV-discordant sexual partners. The HIV Prevention Trials Network 052 trial demonstrated nearly complete prevention of HIV transmission by early treatment of infection, but the generalizability of the results to other risk groups – including intravenous drug users and MSM – has not been determined. Most importantly, the best strategy for use of antiretroviral agents to reduce the spread of HIV at either the individual level or the population level has not been developed, and remains the ultimate goal of this area of investigation.

    Biomedical HIV prevention strategies, such as pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP), represent new opportunities to reduce critically high HIV infection rates among young black men who have sex with men (YBMSM). We report results of 24 dyadic qualitative interviews (N=48), conducted in Los Angeles, CA, exploring how YBMSM and their friends view PrEP and PEP. Interviews were analyzed using a grounded theory approach. Participants had widely divergent levels of knowledge about these prevention methods. Misconceptions and mistrust regarding PrEP were common, and concerns were expressed about PrEP-related stigma and the potential for gossip among peers who might assume a person on PrEP was HIV-positive. Yet participants also framed PrEP and PEP as valuable new options within an expanded "tool kit" of HIV prevention strategies that created possibilities for preventing new HIV infections, dating men with a different HIV status, and decreased anxiety about exposure to HIV. We organized themes around four main areas: (1) information and misinformation about biomedical HIV prevention; (2) expectations about PrEP, sexual behavior, and stigma; (3) gossip, disclosure, and "spreading the word" about PrEP and PEP; and (4) the roles of PrEP and PEP in an expanded HIV prevention tool kit. The findings suggest a need for guidance in navigating the increasingly complex array of HIV-prevention options available to YBMSM. Such "prevention navigation" could counter misconceptions and address barriers, such as stigma and mistrust, while helping YBMSM make informed selections from among expanded HIV prevention options.

    Gender-based violence (GBV) is common in southern Africa. Here we use GBV to include sexual and non-sexual physical violence, emotional abuse, and forms of child sexual abuse. A sizeable literature now links GBV and HIV infection.Sexual violence can lead to HIV infection directly, as trauma increases the risk of transmission. More importantly, GBV increases HIV risk indirectly. Victims of childhood sexual abuse are more likely to be HIV positive, and to have high risk behaviours.GBV perpetrators are at risk of HIV infection, as their victims have often been victimised before and have a high risk of infection. Including perpetrators and victims, perhaps one third of the southern African population is involved in the GBV-HIV dynamic.A randomised controlled trial of income enhancement and gender training reduced GBV and HIV risk behaviours, and a trial of a learning programme reported a non-significant reduction in HIV incidence and reduction of male risk behaviours (primary prevention). Interventions among survivors of GBV can reduce their HIV risk (secondary prevention). Various strategies can reduce spread of HIV from infected GBV survivors (tertiary prevention). Dealing with GBV could have an important effect on the HIV epidemic.A policy shift is necessary. HIV prevention policy should recognise the direct and indirect implications of GBV for HIV prevention, the importance of perpetrator dynamics, and that reduction of GBV should be part of HIV prevention programmes. Effective interventions are likely to include a structural component, and a GBV awareness component. PMID:19033757

    Socio-cultural factors and HIV-related misinformation contribute to the increasing number of Chilean women living with HIV. In spite of this, and to date, few culturally specific prevention activities have been developed for this population. The goal of the present study was to elicit the perspectives of low-income Chilean women regarding HIV and relevant socio-cultural factors, as a forerunner to the development of a culturally appropriate intervention. As part of a mixed-methods study, fifty low-income Chilean women participated in a survey and twenty were selected to participate in prevention, in-depth interviews. Results show evidence of widespread misinformation and misconceptions related to HIV/AIDS. Machismo and marianismo offer major barriers to prevention programme development. Future HIV prevention should stress partner communication, empowerment and improving the education of women vulnerable to HIV. PMID:18432428

    The majority of HIV prevention studies and programs have targeted individuals or operated at the community level. This has also been the standard approach when incorporating technology (e.g., web-based, smartphones) to help improve HIV prevention efforts. The tides have turned for both approaches: greater attention is now focusing on couple-based HIV prevention and using technology to help improve these efforts for maximizing reach and potential impact. To assess the extent that technology has been used to help advance HIV prevention with couples, a literature review was conducted using four databases and included studies that collected data from 2000 to early 2015. Results from this review suggest that technology has primarily been used to help advance HIV prevention with couples as a tool for (1) recruitment and data collection and (2) intervention development. Challenges and limitations of conducting research (e.g., validity of dyadic data) along with future directions for how technology (e.g., mHealth, wearable sensors) can be used to advance HIV prevention with couples are then discussed. Given the growing and near ubiquitous use of the Internet and smartphones, further efforts in the realm of mHealth (e.g., applications or "apps") and eHealth are needed to develop novel couple-focused HIV-preventive interventions.

    Introduction Community mobilizing strategies are essential to health promotion and uptake of HIV prevention. However, there has been little conceptual work conducted to establish the core components of community mobilization, which are needed to guide HIV prevention programming and evaluation. Objectives We aimed to identify the key domains of community mobilization (CM) essential to change health outcomes or behaviors, and to determine whether these hypothesized CM domains were relevant to a rural South African setting. Method We studied social movements and community capacity, empowerment and development literatures, assessing common elements needed to operationalize HIV programs at a community level. After synthesizing these elements into six essential CM domains, we explored the salience of these CM domains qualitatively, through analysis of 10 key informant in-depth-interviews and seven focus groups in three villages in Bushbuckridge. Results CM domains include: 1) shared concerns, 2) critical consciousness, 3) organizational structures/networks, 4) leadership (individual and/or institutional), 5) collective activities/actions, and 6) social cohesion. Qualitative data indicated that the proposed domains tapped into theoretically consistent constructs comprising aspects of CM processes. Some domains, extracted from largely Western theory, required little adaptation for the South African context; others translated less effortlessly. For example, critical consciousness to collectively question and resolve community challenges functioned as expected. However, organizations/networks, while essential, operated differently than originally hypothesized - not through formal organizations, but through diffuse family networks. Conclusions To date, few community mobilizing efforts in HIV prevention have clearly defined the meaning and domains of CM prior to intervention design. We distilled six CM domains from the literature; all were pertinent to mobilization in rural

    Risk compensation has been called the “Achilles’ heel” of HIV prevention policies (Cassell et al 2006). This paper examines the behavioral response to male circumcision, a major HIV prevention policy currently being implemented throughout much of Sub-Saharan Africa. Contrary to the presumption of risk compensation, we find that the response due to the perceived reduction in HIV transmission appears to have been a reduction in risky sexual behavior. We suggest a mechanism for this finding: circumcision may reduce fatalism about acquiring HIV/AIDS and increase the salience of the tradeoff between engaging in additional risky behavior and avoiding acquiring HIV. We also find what appears to be a competing effect that does not operate through the circumcision recipient’s belief about the reduction in the risk of acquiring HIV. PMID:26997745

    Hispanics are the fastest growing minority group in North Carolina with increasing incidence of HIV infection. Gender roles, cultural expectations, and acculturation of women may explain some of Hispanic women's risks. The perspectives of Hispanic female immigrants and community-based providers were sought to identify services they offer, understand HIV risk factors, and support the adaptation of a best-evidence HIV behavioural intervention for Hispanic women. Two sets of focus groups were conducted to explicate risks and the opportunities to reach women or couples and the feasibility to conduct HIV prevention in an acceptable manner. Salient findings were that Hispanic female immigrants lacked accurate HIV/AIDS and STI knowledge and that traditional gender roles shaped issues surrounding sexual behaviour and HIV risks, as well as condom use, partner communication, and multiple sexual partnerships. Intervention implications are discussed such as developing and adapting culturally appropriate HIV prevention interventions for Hispanics that address gender roles and partner communication.

    Worldwide, transgender women who engage in sex work have a disproportionate risk for HIV compared with natal male and female sex workers. We reviewed recent epidemiological research on HIV in transgender women and show that transgender women sex workers (TSW) face unique structural, interpersonal, and individual vulnerabilities that contribute to risk for HIV. Only six studies of evidence-based prevention interventions were identified, none of which focused exclusively on TSW. We developed a deterministic model based on findings related to HIV risks and interventions. The model examines HIV prevention approaches in TSW in two settings (Lima, Peru and San Francisco, CA, USA) to identify which interventions would probably achieve the UN goal of 50% reduction in HIV incidence in 10 years. A combination of interventions that achieves small changes in behaviour and low coverage of biomedical interventions was promising in both settings, suggesting that the expansion of prevention services in TSW would be highly effective. However, this expansion needs appropriate sustainable interventions to tackle the upstream drivers of HIV risk and successfully reach this population. Case studies of six countries show context-specific issues that should inform development and implementation of key interventions across heterogeneous settings. We summarise the evidence and knowledge gaps that affect the HIV epidemic in TSW, and propose a research agenda to improve HIV services and policies for this population. PMID:25059941

    Since the start of the HIV epidemic we have witnessed significant advances in our understanding of the impact of HIV disease worldwide. Further, breakthroughs in treatment and the rapid expansion of HIV care and treatment programs in heavily impacted countries over the past five years are potentially critical assets in a comprehensive approach to controlling the continued spread of HIV globally. A strategic approach to controlling the epidemic requires continued and comparable expansion and integration of care, treatment, and prevention programs. As every new infection involves transmission, whether vertically or horizontally, from a person already living with HIV/AIDS (PLWHA), integration of HIV prevention into HIV care settings has the potential to prevent thousands of new infections, as well as improve the lives of PLWHAs. In this paper, we highlight how to better utilize opportunities created by the antiretroviral (ARV) roll-out to achieve more effective prevention, particularly in Sub Saharan Africa. We offer specific recommendations for action in the domains of healthcare policy and practice in order to better utilize the advances in HIV treatment to advance HIV prevention. PMID:18641470

  15. Advances in HIV treatment and prevention: should treatment optimism lead to prevention pessimism?

    Advances in HIV treatment have changed the natural history of HIV disease and improved the life of infected people. But, paradoxically, the transformation of a lethal disease into a chronic condition has lead many people to pessimism regarding the future of HIV prevention. Post-exposure prophylaxis and prophylaxis of vertical transmission have added new tools, although they do not change the main features of HIV prevention which still relies on safer drug use and safer sex. The role assigned to HIV testing started to change in some countries where it had not been encouraged; however the impact of these changes appears still very limited, except for prevention of vertical transmission. Recent developments should be placed in the whole historical perspective of HIV infection: after the early period of dramatic favourable changes (around 1990), positive changes in attitudes and behaviour have slowed down or even stabilized. Proofs of 'relapse' are, however, still tenuous. The impact of therapeutic changes is combined with the normalization process of HIV infection issues. In the general population, HIV infection seems a more remote personal and social concern and the perception of risk has decreased. The changes in the social context of prevention are more diverse. On one hand, some social norms renewed during the HIV era may have long-lasting effects. The acknowledgement of social and human rights of homosexuals and drug users, stimulated by the AIDS movement, has entered a long-term process and may continue to support preventive behaviours. On the other hand, the exceptionalist alliance which supported and stimulated the HIV policies is weakening. This process might be accelerated by improved therapeutic perspectives. The main challenge is the success of the integration of HIV prevention in broader public health policies (including prevention of STI transmission, family planning, health promotion, etc.) without losing advances in prevention strategies gained in the

  16. Broadly Neutralizing Anti-HIV Antibodies Prevent HIV Infection of Mucosal Tissue Ex Vivo

    Broadly neutralizing monoclonal antibodies (nAbs) specific for HIV are being investigated for use in HIV prevention. Due to their ability to inhibit HIV attachment to and entry into target cells, nAbs may be suitable for use as topical HIV microbicides. As such, they would present an alternative intervention for individuals who may not benefit from using antiretroviral-based products for HIV prevention. We theorize that nAbs can inhibit viral transmission through mucosal tissue, thus reducing the incidence of HIV infection. The efficacy of the PG9, PG16, VRC01, and 4E10 antibodies was evaluated in an ex vivo human model of mucosal HIV transmission. nAbs reduced HIV transmission, causing 1.5- to 2-log10 reductions in HIV replication in ectocervical tissues and ≈3-log10 reductions in HIV replication in colonic tissues over 21 days. These antibodies demonstrated greater potency in colonic tissues, with a 50-fold higher dose being required to reduce transmission in ectocervical tissues. Importantly, nAbs retained their potency and reduced viral transmission in the presence of whole semen. No changes in tissue viability or immune activation were observed in colonic or ectocervical tissue after nAb exposure. Our data suggest that topically applied nAbs are safe and effective against HIV infection of mucosal tissue and support further development of nAbs as a topical microbicide that could be used for anal as well as vaginal protection.

    To explore how people living with HIV (PLHIV) and in care encourage others to adopt HIV-protective behaviours, we conducted in-depth interviews with a purposive sample of 40 HIV clinic patients in Kampala, Uganda. Content analysis was used to examine the message content, trigger events, and outcomes of HIV-prevention advocacy events initiated by the HIV clients with members of their social networks. The content themes included encouraging specific behaviours, such as HIV testing and treatment, condom use and non-promiscuity, as well as more general cautionary messages about protecting oneself from HIV infection. Common triggers for bringing up HIV-prevention advocacy information in a discussion or conversation included: wanting to prevent the targeted person from ‘falling into the same problems,’ wanting to benefit oneself with regard to avoiding re-infection, out of concern that the target would engage in higher-risk behaviour, due to observed changes in the target’s health, and to convey information after receiving treatment at the clinic. The participants mostly reported positive or neutral responses to these advocacy events; negative responses were rare. Interventions to empower PLHIV to be agents of change could represent a new frontier for HIV prevention. PMID:24910590

    Objective Building a successful combination prevention program requires understanding the community’s local epidemiological profile, the social community norms that shape vulnerability to HIV and access to care, and the available community resources. We carried out a situational analysis in order to shape a comprehensive HIV prevention program that address local barriers to care at multiple contextual levels in the North West Province of South Africa. Method The situational analysis was conducted in two sub-districts in 2012 and guided by an adaptation of WHO’s Strategic Approach, a predominantly qualitative method, including observation of service delivery points and in-depth interviews and focus groups with local leaders, providers, and community members, in order to recommend context-specific HIV prevention strategies. Analysis began during fieldwork with nightly discussions of findings and continued with coding original textual data from the fieldwork notebooks and a select number of recorded interviews. Results We conducted over 200 individual and group interviews and gleaned four principal social barriers to HIV prevention and care, including: HIV fatalism, traditional gender norms, HIV-related stigma, and challenges with communication around HIV, all of which fuel the HIV epidemic. At the different levels of response needed to stem the epidemic, we found evidence of national policies and programs that are mitigating the social risk factors but little community-based responses that address social risk factors to HIV. Conclusions Understanding social and structural barriers to care helped shape our comprehensive HIV prevention program, which address the four ‘themes’ identified into each component of the program. Activities are underway to engage communities, offer community-based testing in high transmission areas, community stigma reduction, and a positive health, dignity and prevention program for stigma reduction and improve communication skills

    Providing antiretroviral therapy (ART) to participants who seroconvert during HIV prevention trials in developing countries is an ethical expectation. Promising treatment to the few seroconverters widens disparities within a resource-poor country and would be unjust. Such an assurance should be done in a way that also improves access to ART for others in the country. US funds for ART in poor countries from the PEPFAR should be available to all countries that host HIV prevention and clinical trials. PMID:17545698

    Around 2.5 million people become infected with HIV each year. This extraordinary toll on human life and public health worldwide will only be reversed with effective prevention. What’s more, in the next few years, it is likely at least, that no single prevention strategy will be sufficient to contain the spread of the disease. There is a need for combination prevention as there is for combination treatment, including biomedical, behavioral, and structural interventions. Expanded HIV prevention must be grounded in a systematic analysis of the epidemic’s dynamics in local contexts. Although 85% of HIV is transmitted sexually, effective combinations of prevention have been shown for people who inject drugs. Combination prevention should be based on scientifically derived evidence, with input and engagement from local communities that fosters the successful integration of care and treatment.

    The current analysis considers the HIV prevention research record in the social sciences. We do so with special reference to what has been termed "AIDS Exceptionalism"- departures from standard public health practice and prevention research priorities in favor of alternative approaches to prevention that, it has been argued, emphasize individual rights at the expense of public health protection. In considering this issue, we review the historical context of the HIV epidemic; empirically demonstrate a pattern of prevention research characterized by systematic neglect of prevention interventions for HIV-infected persons; and articulate a rationale for "Prevention for Positives," supportive prevention efforts tailored to the needs of HIV+ individuals. We then propose a social psychological conceptualization of processes that appear to have influenced developments in HIV prevention research and directed its focus to particular target populations. Our concluding section considers whether there are social and research policy lessons to be learned from the record of HIV prevention research that might improve our ability to addresses effectively, equitably, and in timely fashion future epidemics that play out, as HIV does, at the junction of biology and behavior. At the first quarter century of the AIDS epidemic, it is important to weigh our accomplishments against our failures in the fight against AIDS…Future historians will conclude that we cannot escape responsibility for our failure to use effective, scientifically proven strategies to control the AIDS epidemic…They will also likely regard as tragic those instances when we allowed scarce resources to be used to support ideologically driven "prevention" that only served a particular political agenda.Editorial: A Quarter Century of AIDS.

    A combination of advances spanning from isolation to delivery of potent HIV-specific antibodies has begun to revolutionize understandings of antibody-mediated antiviral activity. As a result, the set of broadly neutralizing and highly protective antibodies has grown in number, diversity, potency, and breadth of viral recognition and neutralization. These antibodies are now being further enhanced by rational engineering of their anti-HIV activities and coupled to cutting edge gene delivery and strategies to optimize their pharmacokinetics and biodistribution. As a result, the prospects for clinical use of HIV-specific antibodies to treat, clear, and prevent HIV infection are gaining momentum. Here we discuss the diverse methods whereby antibodies are being optimized for neutralization potency and breadth, biodistribution, pharmacokinetics, and effector function with the aim of revolutionizing HIV treatment and prevention options.

We present perspectives of HIV agencies on improvements that could lead to an ideal system of HIV prevention, treatment and care. We conducted semi-structured interviews with representatives from 21 HIV agencies offering diverse services in Baltimore, MD. Thematic analysis revealed six key themes: (1) Focusing on HIV prevention, (2) Establishing common entry-points for services, (3) Improving information availability, (4) Streamlining funding streams, (5) Removing competitiveness and (6) Building trust. We recommend that in addition to addressing operational issues regarding service delivery and patient care, initiatives to improve HIV service systems should address underlying social issues such as building trust.

    With HIV funding plateauing and the number of people living with HIV increasing due to the rollout of life-saving antiretroviral therapy, policy makers are faced with increasingly tighter budgets to manage the ongoing HIV epidemic. Cost-effectiveness and modeling analyses can help determine which HIV interventions may be of best value. Incidence remains remarkably high in certain populations and countries, making prevention key to controlling the spread of HIV. This paper briefly reviews concepts in modeling and cost-effectiveness methodology and then examines results of recently published cost-effectiveness analyses on the following HIV prevention strategies: condoms and circumcision, behavioral- or community-based interventions, prevention of mother-to-child transmission, HIV testing, pre-exposure prophylaxis, and treatment as prevention. We find that the majority of published studies demonstrate cost-effectiveness; however, not all interventions are affordable. We urge continued research on combination strategies and methodologies that take into account willingness to pay and budgetary impact. PMID:26830283

    Secondary infectious diseases contribute substantially to morbidity and mortality of people infected with human immunodeficiency virus (HIV). The authors developed comprehensive, practical recommendations for prevention of infectious complications in HIV-infected people. Recommendations are concerned with the pathogens that are more common or more severe in HIV-infected people. Several infectious complications can be prevented by avoiding ingestion of contaminated food or water. Zoonoses can be prevented by precautions to be taken in contacts with animals. The risk of several fungal diseases can be reduced if activities likely to lead to inhalation of spores are avoided. HIV-infected people should be advised how to lower adverse health effects of travel, especially international travel. The potential for infectious complications of sexual activity and illicit drug use should be stressed, and recommendations to reduce the risk are discussed. Recommendations for use of vaccines in HIV-infected people are reviewed. Blood CD4+ lymphocyte concentrations, tuberculin skin testing, Toxoplasma serology, and sexually transmitted disease screening should be performed in certain subsets of HIV-infected people. Guidelines for chemoprophylaxis against Pneumocystis carinii and tuberculosis are presented. Recent data suggest that intravenous immunoglobulin therapy may prevent bacterial infections in HIV-infected children. PMID:1910184

    HIV-1 sequencing has been used extensively in epidemiologic and forensic studies to investigate patterns of HIV-1 transmission. However, the criteria for establishing genetic linkage between HIV-1 strains in HIV-1 prevention trials have not been formalized. The Partners in Prevention HSV/HIV Transmission Study (ClinicaITrials.gov NCT00194519) enrolled 3408 HIV-1 serodiscordant heterosexual African couples to determine the efficacy of genital herpes suppression with acyclovir in reducing HIV-1 transmission. The trial analysis required laboratory confirmation of HIV-1 linkage between enrolled partners in couples in which seroconversion occurred. Here we describe the process and results from HIV-1 sequencing studies used to perform transmission linkage determination in this clinical trial. Consensus Sanger sequencing of env (C2-V3-C3) and gag (p17-p24) genes was performed on plasma HIV-1 RNA from both partners within 3 months of seroconversion; env single molecule or pyrosequencing was also performed in some cases. For linkage, we required monophyletic clustering between HIV-1 sequences in the transmitting and seroconverting partners, and developed a Bayesian algorithm using genetic distances to evaluate the posterior probability of linkage of participants sequences. Adjudicators classified transmissions as linked, unlinked, or indeterminate. Among 151 seroconversion events, we found 108 (71.5%) linked, 40 (26.5%) unlinked, and 3 (2.0%) to have indeterminate transmissions. Nine (8.3%) were linked by consensus gag sequencing only and 8 (7.4%) required deep sequencing of env. In this first use of HIV-1 sequencing to establish endpoints in a large clinical trial, more than one-fourth of transmissions were unlinked to the enrolled partner, illustrating the relevance of these methods in the design of future HIV-1 prevention trials in serodiscordant couples. A hierarchy of sequencing techniques, analysis methods, and expert adjudication contributed to the linkage

    High rates of human immunodeficiency virus (HIV) infection among jail and prison inmates suggest that HIV prevention efforts should focus on incarcerated populations. Overcrowding, the high prevalence of injection drug use, and other high-risk behaviors among inmates create a prime opportunity for public health officials to affect the course of the HIV epidemic if they can remedy these problems. Yet, along with the opportunity, there are certain obstacles that correctional institutions present to public health efforts. The various jurisdictions have differing approaches to HIV prevention and control. Whether testing should be mandatory or voluntary, whether housing should be integrated or segregated by HIV serostatus, and whether condoms, bleach, or clean needles should be made available to the prisoners, are questions hotly debated by public health and correctional officials. Even accurate assessment of risk-taking within the institutions leads to controversy, as asking questions could imply acceptance of the very behaviors correctional officials are trying to prevent. Education and risk-reduction counseling are the least controversial and most widely employed modes of prevention, but the effectiveness of current prevention efforts in reducing HIV transmission in this high-risk population is largely undetermined.

    HIV is transmitted through dyadic exchanges of individuals linked in transitory or permanent networks of varying sizes. To optimize prevention efficacy, a complementary theoretical perspective that bridges key individual level elements with important network elements can be a foundation for developing and implementing HIV interventions with outcomes that are more sustainable over time and have greater dissemination potential. Toward that end, we introduce a Network-Individual-Resource (NIR) model for HIV prevention that recognizes how exchanges of resources between individuals and their networks underlies and sustains HIV-risk behaviors. Individual behavior change for HIV prevention, then, may be dependent on increasing the supportiveness of that individual's relevant networks for such change. Among other implications, an NIR model predicts that the success of prevention efforts depends on whether the prevention efforts (1) prompt behavior changes that can be sustained by the resources the individual or their networks possess; (2) meet individual and network needs and are consistent with the individual's current situation/developmental stage; (3) are trusted and valued; and (4) target high HIV-prevalence networks.

    Previous papers in this supplement have reviewed the evidence of the effectiveness of alternative HIV prevention methods from randomized controlled trials and other studies. This paper draws together the main conclusions from these reviews. A conceptual framework is presented that maps the proximal and distal determinants of sexual HIV transmission and helps to identify the stages in the causal pathway at which each intervention approach acts. The advances, gaps and challenges emerging from the reviews of individual intervention methods are summarized and cross-cutting themes identified. Approximately 90% of HIV prevention trials have found no effect on HIV incidence and we explore the alternative explanations for the large number of 'flat' trials. We conclude that there is no single explanation for these flat results, which may be due to interventions that are ineffective or inappropriately targeted or implemented, or to factors related to the design or conduct of trials. We examine the lessons from these flat results and provide recommendations on what should be done differently in future trials. HIV prevention remains of critical importance in an era of expanded delivery of antiretroviral therapy. In future HIV prevention research, it is important that resources are used as efficiently as possible to provide rigorous evidence of the effectiveness of a wider array of complementary prevention tools.

    Early achievements in biomedical approaches for HIV prevention included physical barriers (condoms), clean injection equipment (both for medical use and for injection drug users), blood and blood product safety, and prevention of mother to child transmission. In recent years, antiretroviral drugs to reduce risk of transmission (when the infected person takes the medicines; treatment as prevention or TasP) or reduce risk of acquisition (when the seronegative person takes them; pre-exposure prophylaxis or PrEP) have proven efficacious. Circumcision of men has also been a major tool relevant for higher prevalence regions such as sub-Saharan Africa. Well-established prevention strategies in the control of sexually transmitted diseases and tuberculosis are highly relevant for HIV (i.e., screening, linkage to care, early treatment, and contact tracing). Unfortunately, only slow progress is being made in some available HIV prevention strategies such as family planning for HIV-infected women who do not want more children and prevention mother-to-child HIV transmission. Current studies seek to integrate strategies into approaches that combine biomedical, behavioral, and structural methods to achieve prevention synergies. This review identifies the major biomedical approaches demonstrated to be efficacious that are now available. We also highlight the need for behavioral risk reduction and adherence as essential components of any biomedical approach. PMID:23673881

    2009-01-01

    Worldwide, nearly half of all individuals living with HIV are now women, who acquire the virus largely by heterosexual exposure. With an HIV vaccine likely to be years away, topical microbicide formulations applied vaginally or rectally are being investigated as another strategy for HIV prevention. A review of preclinical and clinical research on the development of microbicides formulated to prevent vaginal HIV transmission yielded 118 studies: 73 preclinical and 45 clinical. Preclinical research included in-vitro assays and cervical explant models, as well as animal models. Clinical research included phase I and II/IIb safety studies, and phase III efficacy studies. Whereas most phase I and phase II clinical trials have found microbicide compounds to be safe and well tolerated, phase III trials completed to date have not demonstrated efficacy in preventing HIV transmission. Topical microbicides are grouped into five classes of agents, based on where they disrupt the pathway of sexual transmission of HIV. These classes include surfactants/membrane disruptors, vaginal milieu protectors, viral entry inhibitors, reverse transcriptase inhibitors, and a fifth group whose mechanism is unknown. The trajectory of microbicide development has been toward agents that block more specific virus—host cell interactions. Microbicide clinical trials face scientifically and ethically complex issues, such as the choice of placebo gel, the potential for viral resistance, and the inclusion of HIV-infected participants. Assessment of combination agents will most likely advance this field of research. PMID:18992405

    Purpose of review This review provides an update on current developments with prevention, treatment and cure strategies in the field of pediatric HIV. Recent findings/Summary There has been tremendous progress in the prevention and treatment of pediatric HIV infection. With new strategies for prevention of mother-to-child transmission, we are growing ever closer towards elimination of pediatric HIV, though challenges with retention of pregnant woman and their HIV-exposed infants remain. Ongoing vigilance regarding the potential hazards of in utero ART exposure to infants continues with no significant alarms yet identified. Though cure has not been achieved, evidence of the impact of early treatment on reducing HIV-1 reservoir size with subsequent prolonged remission has enlivened efforts to rapidly identify and treat HIV-infected newborns. There is an increasing array of treatment options for pediatric patients and reassuring evidence regarding long-term complications of ART. Unfortunately, despite evidence suggesting the benefit of early treatment, timely identification and treatment of children remains a challenge. Better strategies for effective case-finding and engagement in care are urgently needed in addition to an improved understanding of how to retain HIV-positive children and adolescents on treatment. However, further emboldened by recent international commitments and robust global support, the future is hopeful. PMID:26709366

    Sex work occurs to meet the demand for sexual services and is a universal phenomenon. In Africa sex work takes many forms and is an important source of income for many women. Yet sex worker reproductive health needs remain largely unmet. The criminalisation of sex work; community and service provider stigma; violence; substance use and limited access to health services and prevention commodities contribute to the high HIV burden evident among female sex workers in Africa. Following UNAIDS' three pillar approach to HIV prevention and sex work we present an overview of current opportunities, barriers and suggestions to improve HIV prevention policy and programming for sex work in Africa. Universal access to a comprehensive package of HIV services is the first pillar. Reproductive health commodities; voluntary and anonymous HIV counselling and testing; treatment of sexually transmitted infections, HIV and opportunistic infections; harm reduction for substance use and psychosocial support services make up the recommended package of services. The second pillar is a sex worker-supportive environment. The inclusion of sex worker programmes within national HIV strategic planning; sex worker-led community mobilisation and the establishment of sex work community networks (comprised of sex workers, health service providers, law enforcers and other stakeholders) enable effective programme implementation and are recommended. The reduction of sex worker vulnerability and addressing structural issues form the final pillar. The decriminalisation of sex work; development of supportive policy; gender equality and economic development are key factors that need to be addressed to increase sex worker resilience. Evidence supports the public health benefit of human rights based approaches to HIV prevention; moralistic and restrictive policy and laws towards sex work are harmful and should be removed. The establishment of these pillars will increase sex worker safety and enhance the

    An overall decrease of HIV prevalence is now observed in several key Asian countries due to effective prevention programs. The decrease in HIV prevalence and incidence may further improve with the scale-up of combination prevention interventions. The implementation of future prevention trials then faces important challenges. The opportunity to identify heterosexual populations at high risk such as female sex workers may rapidly wane. With unabating HIV epidemics among men who have sex with men (MSM) and transgender (TG) populations, an effective vaccine would likely be the only option to turn the epidemic. It is more likely that efficacy trials will occur among MSM and TG because their higher HIV incidence permits smaller and less costly trials. The constantly evolving patterns of HIV-1 diversity in the region suggest close monitoring of the molecular HIV epidemic in potential target populations for HIV vaccine efficacy trials. CRF01_AE remains predominant in southeast Asian countries and MSM populations in China. This relatively steady pattern is conducive to regional efficacy trials, and as efficacy warrants, to regional licensure. While vaccines inducing nonneutralizing antibodies have promise against HIV acquisition, vaccines designed to induce broadly neutralizing antibodies and cell-mediated immune responses of greater breadth and depth in the mucosal compartments should be considered for testing in MSM and TG. The rationale and design of efficacy trials of combination prevention modalities such as HIV vaccine and preexposure prophylaxis (PrEP) remain hypothetical, require high adherence to PrEP, are more costly, and present new regulatory challenges. The prioritization of prevention interventions should be driven by the HIV epidemic and decided by the country-specific health and regulatory authorities. Modeling the impact and cost-benefit may help this decision process. PMID:26107771

    Despite growing recognition of the important role implementation plays in successful prevention efforts, relatively little work has sought to demonstrate a causal relationship between implementation factors and participant outcomes. In turn, failure to explore the implementation-to-outcome link limits our understanding of the mechanisms essential to successful programming. This gap is partially due to the inability of current methodological procedures within prevention science to account for the multitude of confounders responsible for variation in implementation factors (i.e., selection bias). The current paper illustrates how propensity and marginal structural models can be used to improve causal inferences involving implementation factors not easily randomized (e.g., participant attendance). We first present analytic steps for simultaneously evaluating the impact of multiple implementation factors on prevention program outcome. Then, we demonstrate this approach for evaluating the impact of enrollment and attendance in a family program, over and above the impact of a school-based program, within PROSPER, a large-scale real-world prevention trial. Findings illustrate the capacity of this approach to successfully account for confounders that influence enrollment and attendance, thereby more accurately representing true causal relations. For instance, after accounting for selection bias, we observed a 5% reduction in the prevalence of 11th grade underage drinking for those who chose to receive a family program and school program compared to those who received only the school program. Further, we detected a 7% reduction in underage drinking for those with high attendance in the family program. PMID:23430578

    Almost three decades have elapsed since researchers identified HIV as the cause of AIDS, with current estimates from UNAIDS that 33.4 million adults were living with HIV/AIDS in 2008. Two-thirds of this burden of disease is in Sub-Saharan Africa, and 60% of those infected are women. The disease still remains incurable and current prevention strategies including abstinence, male/female condom use and male circumcision are only partially effective. New strategies to curb the epidemic are urgently needed. Scientists are diligently exploring HIV prevention methods that are safe, effective and affordable. These new biological interventions include oral pre- exposure prophylaxis using oral antiretroviral (ARV) drugs, ARV treatment in HIV-infected persons to reduce transmission and topical ARV-based microbicide formulations.

  2. Couple-oriented prenatal HIV counseling for HIV primary prevention: an acceptability study

    PubMed Central

    2010-01-01

    Background A large proportion of the 2.5 million new adult HIV infections that occurred worldwide in 2007 were in stable couples. Feasible and acceptable strategies to improve HIV prevention in a conjugal context are scarce. In the preparatory phase of the ANRS 12127 Prenahtest multi-site HIV prevention trial, we assessed the acceptability of couple-oriented post-test HIV counseling (COC) and men's involvement within prenatal care services, among pregnant women, male partners and health care workers in Cameroon, Dominican Republic, Georgia and India. Methods Quantitative and qualitative research methods were used: direct observations of health services; in-depth interviews with women, men and health care workers; monitoring of the COC intervention and exit interviews with COC participants. Results In-depth interviews conducted with 92 key informants across the four sites indicated that men rarely participated in antenatal care (ANC) services, mainly because these are traditionally and programmatically a woman's domain. However men's involvement was reported to be acceptable and needed in order to improve ANC and HIV prevention services. COC was considered by the respondents to be a feasible and acceptable strategy to actively encourage men to participate in prenatal HIV counseling and testing and overall in reproductive health services. Conclusions One of the keys to men's involvement within prenatal HIV counseling and testing is the better understanding of couple relationships, attitudes and communication patterns between men and women, in terms of HIV and sexual and reproductive health; this conjugal context should be taken into account in the provision of quality prenatal HIV counseling, which aims at integrated PMTCT and primary prevention of HIV.

    There is a strong push to conduct large-scale randomized controlled study designs in HIV prevention studies. In these randomized controlled studies, the primary research objective is typically to determine the treatment effect based on some biological outcome (eg, HIV infection). But many unused self-reported outcomes are also being collected. We illustrate the extent of this problem using the EXPLORE data as an example. PMID:27031292

    The core objectives of this study were to document the process by which a community-based organization replicated and adapted an experimentally developed intervention to its own use and to explore the effectiveness of that HIV prevention program for male prostitutes and other patrons in New York City "hustler" bars. The intervention model employed was based on previous research with gay men (Kelly, St. Lawrence, Diaz, et al., 1991; Kelly, St. Lawrence, Stevenson, et al., 1992) and inspired by diffusion of innovation theory (Rogers, 1995). The effects of the current intervention were assessed on a sample of 1,741 male prostitutes and bar patrons. Analyses indicated significant reductions in paid, unprotected sexual intercourse and oral sex following the intervention. Analyses further indicated that the data were partially consistent with the program's model, which specified that norms were the putative mediator of behavior change in the intervention. Also, the intervention's effects varied by bar and by participants' race/ethnicity. Data support the utility of the intervention model for an urban sample of men at high risk for HIV infection. The importance of exploring the mechanisms that underlie the intervention is discussed. PMID:9574500

    The HIV epidemic in the United States has affected at least two generations of gay men. Despite numerous efforts to intervene on this public health crisis, HIV infections continue to escalate, especially among young men. This condition is compounded by an ever-growing number of gay men who are aging and living with HIV. We must enact an innovative and proactive vision and framework for HIV prevention that moves us beyond the undertakings rooted in social-cognitive paradigms that have informed this work for the past 25 years. A new framework for HIV prevention must give voice to gay men; must consider the totality of their lives; must delineate the underlying logic, which directs their relation to sex and HIV; and must concurrently respect their diverse life experiences. This approach should be rooted in a biopsychosocial paradigm, should be informed by both theory and practice, and should be directed by three theoretical lenses--a theory of syndemics, developmental theories, and contextual understandings of HIV disease. Taken together, these elements are a call to action for research and practice psychologists who are working to improve the lives of gay men. PMID:21058777

    South African townships have high HIV prevalence and a strong need for collective action to change normative sexual risk behaviors. This study investigated the relationship between perceptions of individuals about collective efficacy in the community’s ability to prevent HIV and their personal HIV risk behaviors. Men (n=1581) and women (n=718) completed anonymous surveys within four Black African Townships in Cape Town, South Africa from June 2008 to December 2010. Measures included demographics, alcohol use, attitudinal and behavioral norms, sexual health communications, and sexual risk behaviors. In multivariate logistic regressions, men were more likely to endorse collective efficacy if they were married, drank less often in alcohol serving establishments, believed that fewer men approve of HIV risk behaviors, talk more with others about HIV/AIDS, and had more sex partners in the past month. Women were more likely to endorse collective efficacy if they drank alcohol less often, talked more with others about HIV/AIDS, had more sex partners in the past month, but reported fewer unprotected sex acts in the past month. Community level interventions that strengthen collective efficacy beliefs will have to consider both protective and risk behaviors associated with believing that the community is ready and capable of preventing HIV.

    1995-12-01

    A scientist with the National Centre in HIV Epidemiology and Clinical Research at the University of New South Wales in Sydney, Australia, addresses the fact that Australians working in the area of HIV infection have been very successful in prevention, treatment, and care. In the early 1980s, a bipartisan political decision was made to foster an effective partnership between HIV-infected communities, health care providers, and governments. HIV-infected communities included sex workers, prisoners, Aboriginal people, and high profile gay community activists. These three different groups succeeded in forming such a partnership, as reflected in the fact that the annual number of new HIV cases is down to 500 from a peak of 3000 in 1984. A key method used to contain HIV infection was needle-and-syringe exchange programs and continuing access to needles to prevent HIV transmission in the injecting drug community. Even though Australia has all this experience and success, it had a backseat role in ushering in the UNAIDS program because Australia did not contribute a significant share of the agency's relatively small budget (US$100 million/year). If Australia were to give just 10%, it would acquire a front row seat along with the Netherlands, Sweden, Belgium, France, and the UK. These nations have the greatest say as to where UNAIDS funds go. The Australian international aid organization has recently received an increase in funds, $110 million for 4 years to spend on four areas, one of which is HIV/AIDS. Australia has just allocated $25 million for a 5-year program for HIV/STD (sexually transmitted disease) prevention in Indonesia. This money would have been able to buy Australia a leading role in UNAIDS. Australians need to reassess their priorities. Australians can help their neighbors in the Asia-Pacific region move away from their denial of HIV to HIV prevention and care. They can conduct clinical trials of shorter and more user-friendly regimens of antiviral drugs that

    2011-01-01

    The Centers for Disease Control and Prevention (CDC) Sexually Transmitted Disease (STD) Treatment Guidelines were last updated in 2006. To update the “Clinical Guide to Prevention Services” section of the 2010 CDC STD Treatment Guidelines, we reviewed the recent science with reference to interventions designed to prevent acquisition of STDs, including human immunodeficiency virus (HIV) infection. Major interval developments include (1) licensure and uptake of immunization against genital human papillomavirus, (2) validation of male circumcision as a potent prevention tool against acquisition of HIV and some other sexually transmitted infections (STIs), (3) failure of a promising HIV vaccine candidate to afford protection against HIV acquisition, (4) encouragement about the use of antiretroviral agents as preexposure prophylaxis to reduce risk of HIV and herpes simplex virus acquisition, (5) enhanced emphasis on expedited partner management and rescreening for persons infected with Chlamydia trachomatis and Neisseria gonorrhoeae, (6) recognition that behavioral interventions will be needed to address a new trend of sexually transmitted hepatitis C among men who have sex with men, and (7) the availability of a modified female condom. A range of preventive interventions is needed to reduce the risks of acquiring STI, including HIV infection, among sexually active people, and a flexible approach targeted to specific populations should integrate combinations of biomedical, behavioral, and structural interventions. These would ideally involve an array of prevention contexts, including (1) communications and practices among sexual partners, (2) transactions between individual clients and their healthcare providers, and (3) comprehensive population-level strategies for prioritizing prevention research, ensuring accurate outcome assessment, and formulating health policy.

    Objective To conduct a critical review of all HIV prevention intervention studies conducted with adolescents in juvenile justice settings to inform future intervention development. Method PubMed and PsycInfo database searches were conducted for peer-reviewed, published HIV prevention intervention studies with juvenile offenders. Results Sixteen studies were identified (N = 3,700 adolescents). Half of the projects utilized rigorous methodologies to determine intervention effect on behavior change, such as conducting a randomized controlled trial (n = 8). Nine studies reported behaviors at least 3 months post-intervention and five out of nine showed decreases in sexual risk behavior. Conclusions Several HIV prevention programs with juvenile offenders have led to sexual risk reduction, although effect sizes are modest. Most existing programs have neglected to address the impact of family, mental health, and substance use on HIV risk. More work is needed to develop evidence-based interventions that include HIV prevention strategies relevant and appropriate for the juvenile justice setting. PMID:19741021

    2016-05-01

    HIV evades eradication because transcriptionally dormant proviral genomes persist in long-lived reservoirs of resting CD4(+) T cells and myeloid cells, which are the source of viral rebound after cessation of antiretroviral therapy. Dormant HIV genomes readily produce infectious virus upon cellular activation because host transcription factors activated specifically by cell stress and heat shock mediate full-length HIV transcription. The molecular chaperone heat shock protein 90 (Hsp90) is overexpressed during heat shock and activates inducible cellular transcription factors. Here we show that heat shock accelerates HIV transcription through induction of Hsp90 activity, which activates essential HIV-specific cellular transcription factors (NF-κB, NFAT, and STAT5), and that inhibition of Hsp90 greatly reduces gene expression mediated by these factors. More importantly, we show that Hsp90 controls virus transcription in vivo by specific Hsp90 inhibitors in clinical development, tanespimycin (17-(allylamino)-17-demethoxygeldanamycin) and AUY922, which durably prevented viral rebound in HIV-infected humanized NOD scid IL-2Rγ(-/-) bone marrow-liver-thymus mice up to 11 weeks after treatment cessation. Despite the absence of rebound viremia, we were able to recover infectious HIV from PBMC with heat shock. Replication-competent virus was detected in spleen cells from these nonviremic Hsp90 inhibitor-treated mice, indicating the presence of a tissue reservoir of persistent infection. Our novel findings provide in vivo evidence that inhibition of Hsp90 activity prevents HIV gene expression in replication-competent cellular reservoirs that would typically cause rebound in plasma viremia after antiretroviral therapy cessation. Alternating or supplementing Hsp90 inhibitors with current antiretroviral therapy regimens could conceivably suppress rebound viremia from persistent HIV reservoirs. PMID:26957545

    Background: As healthcare providers, dentists are in a unique position to foster behavioural changes that are needed to stem the spread of HIV infection. This study was conducted to assess the role of dentists in the prevention of HIV transmission in Nigeria. Methods: This descriptive cross-sectional survey was conducted from June 2006 to January 2007. A multi-stage sampling technique was used to select 300 practising dentists from all parts of Nigeria. Data were collected through a self-administered questionnaire that focused on dentist demographic details, attitudes towards treating HIV-infected persons, involvement in public or clinic-based patient education on HIV and infection control. Results: Two hundred and fifty-seven questionnaires were returned completed, constituting an 86% response rate. The majority of respondents (77.8%) had their dental practice in the southern part of Nigeria, and 89% were in the age bracket of 21–40 years. HIV education by dentists was ranked as poor, as less than a quarter of respondents routinely educated patients on HIV in the clinic. Only a few dentists (33.3%) were involved in public enlightenment programme on HIV in the previous 12 months. Most of the respondents (93%) reported a willingness to treat HIV-infected patients while observing universal precautions. Good infection barrier practices were adopted by 89.9% of dentists, and disposable cartridges for local anaesthetic agents and dental needles were not reused by 93.4% of the respondents. Autoclaving was the most widely used sterilization method (73.2%), but less than half of the respondents knew how to ascertain whether sterilization was effective. Conclusion: This study revealed that efforts by Nigerian dentists to prevent HIV transmission are presently less than optimal. Therefore, there is a need for sensitisation and motivation through seminars, workshops and lectures. PMID:22135532

    2014-01-01

    Reducing the incidence of HIV infection continues to be a crucial public health priority in the United States, especially among populations at elevated risk such as men who have sex with men, transgender women, people who inject drugs, and racial and ethnic minority communities. Although most HIV prevention efforts to date have focused on changing risky behaviors, the past decade has yielded efficacious new biomedical technologies designed to prevent infection, such as the prophylactic use of antiretroviral drugs and the first indications of an efficacious vaccine. Access to prevention technologies will be a significant part of the next decade’s response to HIV, and advocates are mobilizing to achieve more widespread use of these interventions. These breakthroughs, however, arrive at a time of escalating healthcare costs; health insurance coverage therefore raises pressing new questions about priority-setting and the allocation of responsibility for public health. The goals of this Article are to identify legal challenges and potential solutions for expanding access to biomedical HIV prevention through health insurance coverage. This Article discusses the public policy implications of HIV prevention coverage decisions, assesses possible legal grounds on which insurers may initially deny coverage for these technologies, and evaluates the extent to which these denials may survive external and judicial review. Because several of these legal grounds may be persuasive, particularly denials on the basis of medical necessity, this Article also explores alternative strategies for financing biomedical HIV prevention efforts.

    Every day, more than 1 million people are newly infected with sexually transmitted infections (STIs) that can lead to morbidity, mortality, and an increased risk of human immunodeficiency virus (HIV) acquisition. Existing prevention and management strategies, including behavior change, condom promotion, and therapy have not reduced the global incidence and prevalence, pointing to the need for novel innovative strategies. This review summarizes important issues raised during a satellite session at the first HIV Research for Prevention (R4P) conference, held in Cape Town, on October 31, 2014. We explore key STIs that are challenging public health today, new biomedical prevention approaches including multipurpose prevention technologies (MPTs), and the scientific and regulatory hurdles that must be overcome to make combination prevention tools a reality.

    Numerous studies have established that incarcerated populations are at substantial risk for HIV infection. In response, many jails and prisons have increased HIV prevention and related services. However, although twice as many offenders are under community supervision as are incarcerated at any given time, HIV prevention needs have been largely ignored among probationers and parolees, and little is known about their HIV risk behaviors or HIV prevention needs. Compared with inmates, probationers and parolees have substantially greater opportunities to engage in HIV risk behaviors. In the present study, we describe HIV risk behaviors, knowledge, and prevention education experiences of probationers and parolees in New York City. We find that probationers and parolees have high rates of unprotected sex, and limited current exposure to effective HIV education and prevention interventions. Probation and parole departments need to improve HIV training for officers and make HIV risk reduction services more available. PMID:15342338

    Worldwide, HIV disproportionately affects women who are often unable to negotiate traditional HIV preventive strategies such as condoms. In the absence of an effective vaccine or cure, chemoprophylaxis may be a valuable self-initiated alternative. Topical microbicides have been investigated as one such option. The first generation topical microbicides were non-specific, broad-spectrum antimicrobial agents, including surfactants, polyanions, and acid buffering gels, that generally exhibited contraceptive properties. After extensive clinical study, none prevented HIV infection, and their development was abandoned. Second generation topical microbicides include agents with selective mechanisms of antiviral activity. Most are currently being used for, or have previously been explored as, drugs for treatment of HIV. The most advanced of these is tenofovir 1% gel: the first topical agent shown to significantly reduce HIV infection by 39% compared to placebo. This review summarizes the evolution of topical microbicides for HIV chemoprophylaxis, highlights important concepts learned, and offers current and future considerations for this area of research.

    The rigorous evaluation of the impact of combination HIV prevention packages at the population level will be critical for the future of HIV prevention. In this review, we discuss important considerations for the design and interpretation of cluster randomized controlled trials (C-RCTs) of combination prevention interventions. We focus on three large C-RCTs that will start soon and are designed to test the hypothesis that combination prevention packages, including expanded access to antiretroviral therapy, can substantially reduce HIV incidence. Using a general framework to integrate mathematical modelling analysis into the design, conduct, and analysis of C-RCTs will complement traditional statistical analyses and strengthen the evaluation of the interventions. Importantly, even with combination interventions, it may be challenging to substantially reduce HIV incidence over the 2- to 3-y duration of a C-RCT, unless interventions are scaled up rapidly and key populations are reached. Thus, we propose the innovative use of mathematical modelling to conduct interim analyses, when interim HIV incidence data are not available, to allow the ongoing trials to be modified or adapted to reduce the likelihood of inconclusive outcomes. The preplanned, interactive use of mathematical models during C-RCTs will also provide a valuable opportunity to validate and refine model projections. PMID:22807657

    The efficacy of preventive interventions is related to both the delivery of content and the uptake of that content. Although much research has focused on the quality of delivery, few studies have examined the factors that influence uptake. This study examines how and why participants' engagement-conceptualized as a dynamic process wherein participants interact with each other, the interventionists, and the intervention curriculum-changes over time. We apply growth curve models to repeated measures of engagement obtained from 252 families during a 7-week intervention trial. In the models, we examine (a) whether and how engagement changes over time, and the extent of between-person differences in change; and (b) how those changes and differences are related to chronic and session-specific aspects of family tension, while also controlling for differences across parent sex and 2 versions of the Strengthening Families Program: For Parents and Youth Ages 10-14 (SFP 10-14). Results show that, on average, engagement increased over time, linearly with some deceleration, with substantial differences in both level and rates of change. Higher in-session chronic family tension was related to lower initial levels of engagement but not rates of change. Sessions when families displayed more session-specific tension were characterized by different levels of engagement for parents, depending on their level of chronic tension. Overall, our results highlight the importance of considering engagement as a dynamic construct that changes over time in complex ways. Further understanding of the many factors that influence engagement can promote both better delivery and better uptake of intervention curriculum. PMID:25383795

    Strategies to protect against sexual transmission of HIV include the development of products formulated for topical application, which limit the toxicities associated with systemic oral pre-exposure prophylaxis. Following several clinical trial failures, attention is now focused on antiretroviral (ARV) agents. Highly potent ARV topical formulations provide a female-controlled, targeted, and feasible option for HIV prevention. A recently completed tenofovir gel trial was the first to demonstrate significant protection against HIV acquisition. Topical ARVs have the advantage of delivering high concentration of drug at the site of transmission of HIV, with low systemic absorption. Sustained-release formulations, such as intravaginal rings, will likely improve adherence and can be designed to provide controlled and continuous delivery of ARV combinations. Further studies to test alternative dosing strategies and pharmacokinetic/pharmacodynamic relationships in the genital tract will provide valuable information as the field strives to improve upon the promising tenofovir gel trial results.

    Alcohol use is associated with risks for sexually transmitted infections (STIs), including HIV/AIDS. People meet new sex partners at bars and other places where alcohol is served, and drinking venues facilitate STI transmission through sexual relationships within closely knit sexual networks. This paper reviews HIV prevention interventions conducted in bars, taverns, and informal drinking venues. Interventions designed to reduce HIV risk by altering the social interactions within drinking environments have demonstrated mixed results. Specifically, venue-based social influence models have reduced community-level risk in U.S. gay bars, but these effects have not generalized to gay bars elsewhere or to other populations. Few interventions have sought to alter the structural and physical environments of drinking places for HIV prevention. Uncontrolled program evaluations have reported promising approaches to bar-based structural interventions with gay men and female sex workers. Finally, a small number of studies have examined multilevel approaches that simultaneously intervene at both social and structural levels with encouraging results. Multilevel interventions that take environmental factors into account are needed to guide future HIV prevention efforts delivered within alcohol-serving establishments. PMID:23584060

    Summary The promise of combination HIV prevention—the application of multiple HIV prevention interventions to maximize population-level impact—has never been greater. However, to succeed in achieving significant reductions in HIV incidence, an additional concept needs to be considered—combination implementation. Combination implementation for HIV prevention is defined here as the pragmatic, localized application of evidence-based strategies to realize high sustained uptake and quality of HIV prevention interventions. This review explores diverse implementation strategies including HIV testing and counseling models, task shifting, linkage to and retention in care, antiretroviral therapy support, behavior change, demand creation, and structural interventions and discusses how they could be used in the provision of HIV prevention interventions such as medical male circumcision and treatment as prevention. Only through careful consideration of how to implement and operationalize HIV prevention interventions will the HIV community be able to move from clinical trial evidence to population-level impact.

    The 2016 Conference on Retroviruses and Opportunistic Infections (CROI) highlighted hot spots in HIV infection. Men who have sex with men (MSM), transgender populations, people who inject drugs, fisherfolk, migrants, adolescents, and older adults are heavily impacted in a number of regions. Stigma contributes to risk behaviors and HIV acquisition across populations. HIV testing is a crucial first step in the HIV care continuum, and several large community-based surveys are underway in Africa to increase HIV testing, linkage to care, and uptake of antiretroviral treatment. Advances in preexposure prophylaxis (PrEP) featured prominently at CROI 2016. Two large efficacy trials of a vaginal ring containing the investigational drug dapivirine demonstrated efficacy and safety in preventing HIV infections in women in Africa. Data on the safety of long-acting injectable PrEP and several investigational PrEP drugs and formulations were also presented. Knowledge and use of PrEP among MSM in the United States appears to be increasing, and high uptake was seen among black MSM when provided as part of a culturally tailored support program. The use of broadly neutralizing antibodies for HIV prevention is a novel and promising approach to be evaluated in efficacy trials. PMID:27398859

    The HIV-1 pandemic is a complex mix of diverse epidemics within and between countries and regions of the world, and is undoubtedly the defining public-health crisis of our time. Research has deepened our understanding of how the virus replicates, manipulates, and hides in an infected person. Although our understanding of pathogenesis and transmission dynamics has become more nuanced and prevention options have expanded, a cure or protective vaccine remains elusive. Antiretroviral treatment has transformed AIDS from an inevitably fatal condition to a chronic, manageable disease in some settings. This transformation has yet to be realised in those parts of the world that continue to bear a disproportionate burden of new HIV-1 infections and are most a% ected by increasing morbidity and mortality. This Seminar provides an update on epidemiology, pathogenesis, treatment, and prevention interventions pertinent to HIV-1. PMID:16890836

    Interest in social and structural interventions for HIV prevention is growing. Such approaches modify social norms, institutions, laws, and policies to reduce vulnerability and create environments in which individuals can protect themselves against HIV infection. Examples include expanding access to sterile syringes for injecting drug users and subsidizing stable housing for low-income people. Evidence of the effectiveness of such interventions is emerging despite scientific and political obstacles to their development, implementation, and evaluation. The U.S. government can help build the evidence base for such interventions. It can also implement those with demonstrated or promising results as part of a cost-effective HIV prevention strategy domestically and globally. PMID:19887406

    PubMed Central

    2009-01-01

    Background After more than 25 years, public health programs have not been able to sufficiently reduce the number of new HIV infections. Over 7,000 people become infected with HIV every day. Lack of convincing evidence of cost-effectiveness (CE) may be one of the reasons why implementation of effective programs is not occurring at sufficient scale. This paper identifies, summarizes and critiques the CE literature related to HIV-prevention interventions in low- and middle-income countries during 2005-2008. Methods Systematic identification of publications was conducted through several methods: electronic databases, internet search of international organizations and major funding/implementing agencies, and journal browsing. Inclusion criteria included: HIV prevention intervention, year for publication (2005-2008), setting (low- and middle-income countries), and CE estimation (empirical or modeling) using outcomes in terms of cost per HIV infection averted and/or cost per disability-adjusted life year (DALY) or quality-adjusted life year (QALY). Results We found 21 distinct studies analyzing the CE of HIV-prevention interventions published in the past four years (2005-2008). Seventeen CE studies analyzed biomedical interventions; only a few dealt with behavioral and environmental/structural interventions. Sixteen studies focused on sub-Saharan Africa, and only a handful on Asia, Latin America and Eastern Europe. Many HIV-prevention interventions are very cost effective in absolute terms (using costs per DALY averted), and also in country-specific relative terms (in cost per DALY measured as percentage of GDP per capita). Conclusion There are several types of interventions for which CE studies are still not available or insufficient, including surveillance, abstinence, school-based education, universal precautions, prevention for positives and most structural interventions. The sparse CE evidence available is not easily comparable; thus, not very useful for decision

    2015-01-01

    Every day, more than 1 million people are newly infected with sexually transmitted infections (STIs) that can lead to morbidity, mortality, and an increased risk of human immunodeficiency virus (HIV) acquisition. Existing prevention and management strategies, including behavior change, condom promotion, and therapy have not reduced the global incidence and prevalence, pointing to the need for novel innovative strategies. This review summarizes important issues raised during a satellite session at the first HIV R4P conference, held in Cape Town, on October 31, 2014. We explore key STIs that are challenging public health today; new biomedical prevention approaches including multipurpose prevention technologies (MPTs); and the scientific and regulatory hurdles that must be overcome to make combination prevention tools a reality.

    Purpose To explore the feasibility of engaging community businesses in HIV prevention. Design Randomly selected business owners/managers were asked to display discreetly wrapped condoms and brochures provided free-of-charge for 3 months. Assessments were conducted at baseline, mid-, and post-program. Customer feedback was obtained through an online survey. Setting San Diego, California neighborhood with a high rate of AIDS. Subjects Fifty-one business owners/managers representing 10 retail categories, and 52 customers. Measures Participation rates, descriptive characteristics, number of condoms and brochures distributed, customer feedback, business owners'/managers' program satisfaction and willingness to provide future support for HIV prevention. Analysis Kruskal-Wallis, Mann-Whitney U, Fisher's exact, and McNemar's tests were used to analyze data. Results The 20 business owners/managers (39%) who agreed to distribute condoms and brochures reported fewer years in business and more employees than those who agreed only to distribute brochures (20%) or refused to participate (41%), p <.05. Bars were the easiest of ten retail categories to recruit. Businesses with more employees and customers distributed more condoms and brochures, p < .05. More than 90% of customers supported distributing condoms and brochures in businesses and 96% of business owners/managers described their program experience as “positive.” Conclusion Businesses are willing to distribute condoms and brochures to prevent HIV. Policies to increase business participation in HIV prevention should be developed and tested. PMID:20465150

    Planning an intervention to prevent infections with the human immunodeficiency virus (HIV) should be guided by local epidemiological and socioeconomic conditions. The socioeconomic setting and existing public service capacity determine whether an intervention can have a significant outcome in terms of a reduction in a defined risk. The epidemiological context determines whether such risk reduction translates into a measurable impact on HIV incidence. Measurement of variables describing the epidemiological context can be used to determine the local suitability of interventions, thereby guiding planners and policy-makers in their choice of intervention. Such measurements also permit the retrospective analysis of the impact of interventions where HIV incidence was not recorded. The epidemiological context is defined for four different categories of intervention, shown to be effective in lower-income countries by randomized controlled trials. Appropriate indicators for the epidemiological context and methodological guidelines for their measurement are proposed. Their use in the transfer of a successful intervention from one context to another and in scaling up the effort to control HIV infection is explored. These indicators should provide a useful resource for those involved in planning HIV prevention interventions. PMID:11799444

    Text messaging is a potential HIV-prevention tool for men who have sex with men (MSM), specifically young MSM and MSM of color. To determine the willingness of MSM to receive text messages as part of an HIV-prevention intervention, we administered an online survey to MSM recruited from MySpace.com, which included questions about mobile phone ownership and willingness to participate in a future text message-based HIV research study. Of participants, 85% (n = 5,378) reported owning a mobile phone and 49% (n = 2,483) of mobile phone owners reported being willing to receive text messages in a future HIV research study. Black and Hispanic men were more willing than White non-Hispanic men to receive text messages. Men with a college degree were less willing to receive texts than men with a high school level of education, and men >22 years old were less likely to be willing to receive texts than those younger than 22 years of age. The authors' findings demonstrate that willingness to receive text messages as part of an HIV research study is moderate, and mirrors patterns of text message use in age and race. Variations in willingness should be taken into account when designing and implementing future interventions. PMID:23905653

    This article explores how notions of the individual and population are evoked in two ongoing HIV treatment as prevention (TasP) implementation studies in Swaziland. By contrasting policy discourses with lived kinship experiences of people living with HIV, we seek to understand how TasP unfolds in the Swazi context. Data collection consisted of eight focus group discussions with people living with HIV who were members of support groups to examine their perspectives about TasP. In addition, 18 key informant interviews were conducted with study team members, national-level policy-makers and NGO representatives involved in the design of health communication messages about TasP in Swaziland. Thematic analysis was used to identify recurrent themes in transcripts and field notes. Policy-makers and people living with HIV actively resisted framing HIV treatment as a prevention technology but promoted it as (earlier) access to treatment for all. TasP was not conceptualised in terms of individual or societal benefits, which are characteristic of international public health debates; rather its locally situated meanings were embedded in kinship experiences, concerns about taking responsibility for one's own health and others, local biomedical knowledge about drug resistance, and secrecy. The findings from this study suggest that more attention is needed to understand how the global discourse of TasP becomes shaped in practice in different cultural contexts. PMID:27421047

    This paper presents a qualitative investigation of peer mentoring among HIV seropositive injection drug users in a randomized controlled trial, the INSPIRE study. Qualitative analyses of 68 in-depth open-ended interviews conducted in 2005 in Baltimore, New York, Miami, and San Francisco revealed that these individuals conceptualized themselves as change agents through the identity of peer mentor at the three related domains of individual, interpersonal, and community-level change. Implications for program development and future research of peer mentoring as a mechanism for HIV prevention are discussed.

    Background An interim analysis of data from the HIV Prevention Trials Network (HPTN) 052 trial showed that antiretroviral therapy (ART) prevented more than 96% of genetically linked infections caused by human immunodeficiency virus type 1 (HIV-1) in serodiscordant couples. ART was then offered to all patients with HIV-1 infection (index participants). The study included more than 5 years of follow-up to assess the durability of such therapy for the prevention of HIV-1 transmission. Methods We randomly assigned 1763 index participants to receive either early or delayed ART. In the early-ART group, 886 participants started therapy at enrollment (CD4+ count, 350 to 550 cells per cubic millimeter). In the delayed-ART group, 877 participants started therapy after two consecutive CD4+ counts fell below 250 cells per cubic millimeter or if an illness indicative of the acquired immunodeficiency syndrome (i.e., an AIDS-defining illness) developed. The primary study end point was the diagnosis of genetically linked HIV-1 infection in the previously HIV-1-negative partner in an intention-to-treat analysis. Results Index participants were followed for 10,031 person-years; partners were followed for 8509 person-years. Among partners, 78 HIV-1 infections were observed during the trial (annual incidence, 0.9%; 95% confidence interval [CI], 0.7 to 1.1). Viral-linkage status was determined for 72 (92%) of the partner infections. Of these infections, 46 were linked (3 in the early-ART group and 43 in the delayed-ART group; incidence, 0.5%; 95% CI, 0.4 to 0.7) and 26 were unlinked (14 in the early-ART group and 12 in the delayed-ART group; incidence, 0.3%; 95% CI, 0.2 to 0.4). Early ART was associated with a 93% lower risk of linked partner infection than was delayed ART (hazard ratio, 0.07; 95% CI, 0.02 to 0.22). No linked infections were observed when HIV-1 infection was stably suppressed by ART in the index participant. Conclusions The early initiation of ART led to a sustained

    This update on the epidemiology and prevention of HIV in the United States is intended to provide contextual background that will help inform an understanding of recent developments in the domestic HIV epidemic. We describe the epidemiology of HIV disease in the US and the HIV continuum of care based on data collected primarily through HIV surveillance systems led by the Centers for Disease Control and Prevention including HIV incidence, prevalence, comorbidities and death. Populations and geographic regions disparately impacted by HIV are also highlighted. The HIV prevention armamentarium is also described including behavioral approaches to prevention, the emerging availability of biomedical prevention interventions such as pre-exposure prophylaxis, and structural and population-level interventions including treatment as prevention. Finally gaps in our understanding of the epidemic are underscored and suggestions for future epidemiologic research are proposed. PMID:25960941

    Many goods are transported from Bangalore and Bombay along the highway which cuts across the farmlands of Belgaum district, Karnataka state. As they pass through Belgaum, truck drivers have sex with prostitutes. Local devadasis, women who belong to a Hindu sect, rely upon sex work, concubinage, and begging to survive. In 1993, MYRADA, a nongovernmental organization (NGO), determined that more than 9% of these women seeking HIV testing in the district were seropositive for the virus. Acting upon this finding, MYRADA launched an HIV prevention program among the devadasis. The program soon expanded to include the general population amid concerns that targeting devadasis would further marginalize them and not enhance their risk reduction behavior. Less than half of the sex workers and less than 25% of all women interviewed had heard of AIDS. MYRADA therefore focused upon training specific groups, such as volunteer health workers, traditional midwives, barbers, and government employees with extensive public contact, to act as HIV educators. The NGO also uses village meetings, folk and popular music, billboards, traveling programs of movies and music videos, street theater, and newspaper advertisements to communicate HIV prevention messages. Moreover, in the interest of getting prevention messages to the large number of illiterate people, print materials were redesigned to carry fewer words and more pictures. MYRADA is close to ensuring that no one in the area needs to walk more than 10 minutes to buy a condom. PMID:12319990

    HIV prevention interventions can help college students engage in safe sexual behaviors. We used the Information, Motivation, Behavioral Skills model to frame four focus group discussions with Black women (n = 32) attending a historically Black college/university or a traditional university to understand their HIV prevention needs. Participants wanted clear information about sexually transmitted infections/HIV and access to contraception. Motivators for practicing safe sex were related to cultural and religious expectations, desire to avoid pregnancy, and conscious efforts to defy racial stereotypes. Barriers to practicing safe sex included issues of accountability, stigma associated with accessing HIV testing/prevention services, and media influences. We found general consensus about the need to develop skill-building HIV prevention interventions focused on communication skills, condom negotiation, access to services, and empowerment. We offer insight into culture- and age-appropriate HIV prevention for Black college women to guide the development of future interventions. PMID:26875473

    Internalized heterosexism (IH), or the internalization of societal antihomosexual attitudes, has been consistently linked to depression and low self-esteem among gay men, and it has been inconclusively associated with substance use and sexual risk in gay and bisexual men. Using structural equation modeling, the authors tested a model framed in social action theory (C. K. Ewart, 1991, 2004) in which IH is associated with HIV transmission risk and poor adherence to HIV antiretroviral therapy (ART) through the mechanisms of negative affect and stimulant use. Data from a sample of 465 gay-identified men interviewed as part of an HIV risk reduction behavioral trial were used to test the fit of the model. Results support the hypothesized model in which IH was associated with unprotected receptive (but not insertive) anal intercourse with HIV-negative or unknown HIV status partners, and with ART nonadherence indirectly via increased negative affect and more regular stimulant use. The model accounted for 15% of the variance in unprotected receptive anal intercourse and 17% of the variance in ART nonadherence. Findings support the potential utility of addressing IH in HIV prevention and treatment with HIV-positive gay men. PMID:18837600

    Introduction Social protection is high on the HIV-prevention agenda for youth in sub-Saharan Africa. However, questions remain: How do unconditional cash transfers work? What is the effect of augmenting cash provision with social care? And can “cash plus care” social protection reduce risks for adolescents most vulnerable to infection? This study tackles these questions by first identifying mediated pathways to adolescent HIV risks and then examining potential main and moderating effects of social protection in South Africa. Methods This study was a prospective observational study of 3515 10-to-17-year-olds (56.7% female; 96.8% one-year retention). Within randomly selected census areas in four rural and urban districts in two South African provinces, all homes with a resident adolescent were sampled between 2009/2010 and 2011/2012. Measures included 1) potential structural drivers of HIV infection such as poverty and community violence; 2) HIV risk behaviours; 3) hypothesized psychosocial mediating factors; and 4) types of social protection involving cash and care. Using gender-disaggregated analyses, longitudinal mediation models were tested for potential main and moderating effects of social protection. Results Structural drivers were associated with increased onset of adolescent HIV risk behaviour (p<0.001, B=0.06, SE=0.01), fully mediated by increased psychosocial problems. Both cash and care aspects of social protection were associated with reductions in HIV risk behaviour and psychosocial deprivations. In addition, cash social protection moderated risk pathways: for adolescent girls and boys experiencing more acute structural deprivation, social protection had the greatest associations with HIV risk prevention (e.g. moderation effects for girls: B=−0.08, p<0.002 between structural deprivation and psychosocial problems, and B=−0.07, p<0.001 between psychosocial problems and HIV risk behaviour). Conclusions Adolescents with the greatest structural

    Introduction Treatment as prevention has mobilized new opportunities in preventing HIV transmission and has led to bold new UNAIDS targets in testing, treatment coverage and transmission reduction. These will require not only an increase in investment but also a deeper understanding of the dynamics of combining behavioural, biomedical and structural HIV prevention interventions. High-income countries are making substantial investments in combination HIV prevention, but is this investment leading to a deeper understanding of how to combine interventions? The combining of interventions involves complexity, with many strategies interacting with non-linear and multiplying rather than additive effects. Discussion Drawing on a recent scoping study of the published research evidence in HIV prevention in high-income countries, this paper argues that there is a gap between the evidence currently available and the evidence needed to guide the achieving of these bold targets. The emphasis of HIV prevention intervention research continues to look at one intervention at a time in isolation from its interactions with other interventions, the community and the socio-political context of their implementation. To understand and evaluate the role of a combination of interventions, we need to understand not only what works, but in what circumstances, what role the parts need to play in their relationship with each other, when the combination needs to adapt and identify emergent effects of any resulting synergies. There is little development of evidence-based indicators on how interventions in combination should achieve that strategic advantage and synergy. This commentary discusses the implications of this ongoing situation for future research and the required investment in partnership. We suggest that systems science approaches, which are being increasingly applied in other areas of public health, could provide an expanded vocabulary and analytic tools for understanding these

    This paper compares policies on named HIV testing in the context of HIV prevention in Britain, Hungary and Sweden, and considers the extent to which these policies are based on evidence of effectiveness or on other, more contextual, factors. In Britain, testing has not featured significantly as a prevention strategy, and named testing has generally been carried out only with the voluntary, informed consent of individuals. In Hungary, testing is central to HIV prevention, and is required by law of certain groups. HIV testing is carried out mainly on a voluntary basis in Sweden, but, unlike in Britain, it has been actively promoted by public health authorities. The paper contrasts the 'right not to know' one's HIV status which is widely respected in Britain, with the 'responsibility to find out' which is more pervasive in Hungary and Sweden. Although policy makers in all three countries appear convinced that their's is the right approach, there appears to be as yet a dearth of convincing evidence to support their arguments. PMID:9828953

    The role of HIV specialists in providing primary care to persons living with HIV/AIDS is evolving, given their increased incidence of comorbidities. Multivariate logit analysis compared compliance with sentinel preventive screening tests and interventions among publicly insured Californians with and without access to HIV specialists in 2010. Quality-of-care indicators [visit frequency, CD4 and viral load (VL) assessments, influenza vaccine, tuberculosis (TB) testing, lipid profile, glucose blood test, and Pap smears for women] were related to patient characteristics and provider HIV caseload. There were 9377 adult Medicare enrollees (71% also had Medicaid coverage) and 2076 enrollees with only Medicaid coverage. Adjusted for patient characteristics, patients seeing providers with greater HIV caseloads (>50 HIV patients) were more likely to meet visit frequency guidelines in both Medicare [98%; confidence interval (CI 97.5-98.2) and Medicaid (97%; CI 96.2-98.0), compared to 60% (CI 57.1-62.3) and 45% (CI 38.3-50.4), respectively, seeing providers without large HIV caseloads (p < 0.001). Patients seeing providers with larger caseloads were significantly more likely to have CD4 (p < 0.001), VL (p < 0.001), and TB testing (p < 0.05). A larger percentage of patients seeing large-volume Medicare providers received influenza vaccinations. Provider caseload was unrelated to lipid or glucose assessments or Pap Smears for women. Patients with access to large-volume providers were more likely to meet clinical guidelines for visits, CD4, VL, tuberculosis testing, and influenza vaccinations, and were not less likely to receive primary preventive care. Substantial insufficiencies remain in both monitoring to assess viral suppression and in preventive care. PMID:27610461

    Experience from two HIV-preventive projects among drug abusers in Oslo, Norway, shows that HIV-positive drug abusers carry on their drug abuse independent of visits to residential drug-free treatment or prison. HIV-positive former drug abusers show a tendency to relapse to drug abuse. In terms of HIV-prevention among drug abusers it is important to reduce injection of drugs among HIV-positive drug abusers. Thus, methadone maintenance programmes should be considered in HIV-prevention in Norway. PMID:2363170

    Researchers should protect the welfare of research participants through providing methods to reduce their risk of acquiring HIV. This is especially important given that late-phase HIV vaccine trials enrol HIV-uninfected trial volunteers from high-risk populations. Current ethical guidelines may be difficult for stakeholders to implement, and we know very little about what prevention services researchers are currently providing to participants or their successes, best practices and challenges. We recommend that current normative guidance be systematically reviewed and actual practice at vaccine sites be documented. Adding new tools to the current package of prevention services will involve complex decision making with few set standards, and regulatory and scientific challenges. We recommend that stakeholders (including regulators) convene to consider standards of evidence for new tools, and that decision-making processes be explicitly documented and researched. A further critical ethical task is exploring the threshold at which adding new tools will compromise the validity of trial results. PMID:20429488

    An HIV prevention program was piloted on an acute inpatient admission ward. Patients who volunteered to participate had significantly higher rates of histories of substance use than non-participants, suggesting that patients participated based on rational concerns about past HIV risk behavior. The program consisted of 75 minute sessions once a week for seven weeks and was co-led by an HIV counselor and the ward's social worker. Each session focused on a specific topic and included a short presentation of informational material, viewing of an educational videotape, a discussion, and role play and other educational games. In spite of a wide range in functioning among the participants, discussion was lively and participation was good. The pilot program demonstrates that chronic mentally ill patients can engage in, and benefit from, risk reduction programs and that frank and explicit discussion of sexual issues is well tolerated. Recommendations for improvement in the program are discussed. PMID:1488461

  18. Reviewing the evidence on effectiveness and cost-effectiveness of HIV prevention strategies in Thailand

    2010-01-01

    Background Following universal access to antiretroviral therapy in Thailand, evidence from National AIDS Spending Assessment indicates a decreasing proportion of expenditure on prevention interventions. To prompt policymakers to revitalize HIV prevention, this study identifies a comprehensive list of HIV/AIDs preventive interventions that are likely to be effective and cost-effective in Thailand. Methods A systematic review of the national and international literature on HIV prevention strategies from 1997 to 2008 was undertaken. The outcomes used to consider the effectiveness of HIV prevention interventions were changes in HIV risk behaviour and HIV incidence. Economic evaluations that presented their results in terms of cost per HIV infection averted or cost per quality-adjusted life year (QALY) gained were also included. All studies were assessed against quality criteria. Results The findings demonstrated that school based-sex education plus life-skill programs, voluntary and routine HIV counselling and testing, male condoms, street outreach programs, needle and syringe programs, programs for the prevention of mother-to-child HIV transmission, male circumcision, screening blood products and donated organs for HIV, and increased alcohol tax were all effective in reducing HIV infection among target populations in a cost-effective manner. Conclusion We found very limited local evidence regarding the effectiveness of HIV interventions amongst specific high risk populations. This underlines the urgent need to prioritise health research resources to assess the effectiveness and cost-effectiveness of HIV interventions aimed at reducing HIV infection among high risk groups in Thailand.

    2015-06-01

    This article seeks to advance ethical dialogue on choosing standards of prevention in clinical trials testing improved biomedical prevention methods for HIV. The stakes in this area of research are high, given the continued high rates of infection in many countries and the budget limitations that have constrained efforts to expand treatment for all who are currently HIV-infected. New prevention methods are still needed; at the same time, some existing prevention and treatment interventions have been proven effective but are not yet widely available in the countries where they most urgently needed. The ethical tensions in this field of clinical research are well known and have been the subject of extensive debate. There is no single clinical trial design that can optimize all the ethically important goals and commitments involved in research. Several recent articles have described the current ethical difficulties in designing HIV prevention trials, especially in resource limited settings; however, there is no consensus on how to handle clinical trial design decisions, and existing international ethical guidelines offer conflicting advice. This article acknowledges these deep ethical dilemmas and moves beyond a simple descriptive approach to advance an organized method for considering what clinical trial designs will be ethically acceptable for HIV prevention trials, balancing the relevant criteria and providing justification for specific design decisions.

    Since many evaluations of HIV (human immunodeficiency virus) prevention programmes do not include data on costs, a preliminary analysis of the costs and outputs of a sample of HIV prevention projects was attempted. Case studies, representing six broad HIV prevention strategies in developing countries with differing levels of per capita gross domestic product, were sought on the basis of availability of data and potential generalizability. The six prevention strategies studied were mass media campaigns, peer education programmes, sexually transmitted disease treatment, condom social marketing, safe blood provision, and needle exchange/bleach provision programmes. Financial cost data were abstracted from published studies or were obtained directly from project coordinators. Although estimates of cost-effectiveness were not made, calculations of the relative cost per common process measure of output were compared. Condom distribution costs ranged from US$ 0.02 to 0.70 per condom distributed, and costs of strategies involving personal educational input ranged from US$ 0.15 to 12.59 per contact. PMID:8261563

    As the science demonstrating strong evidence for voluntary medical male circumcision (VMMC) for HIV prevention has evolved, the President's Emergency Plan for AIDS Relief (PEPFAR) has collaborated with international agencies, donors, and partner country governments supporting VMMC programming. Mathematical models forecast that quickly reaching a large number of uncircumcised men with VMMC in strategically chosen populations may dramatically reduce community-level HIV incidence and save billions of dollars in HIV care and treatment costs. Because VMMC is a 1-time procedure that confers life-long partial protection against HIV, programs for adult men are vital short-term investments with long-term benefits. VMMC also provides a unique opportunity to reach boys and men with HIV testing and counseling services and referrals for other HIV services, including treatment. After formal recommendations by WHO in 2007, priority countries have pursued expansion of VMMC. More than 1 million males have received VMMC thus far, with the most notable successes coming from Kenya's Nyanza Province. However, a myriad of necessary cultural, political, and ethical considerations have moderated the pace of overall success. Because many millions more uncircumcised men would benefit from VMMC services now, US President Barack Obama committed PEPFAR to provide 4.7 million males with VMMC by 2014. Innovative circumcision methods-such as medical devices that remove the foreskin without injected anesthesia and/or sutures-are being rigorously evaluated. Incorporation of safe innovations into surgical VMMC programs may provide the opportunity to reach more men more quickly with services and dramatically reduce HIV incidence for all. PMID:22797745

    2014-01-01

    Optimal adherence to antiretroviral therapy (ART) is central to achieving viral suppression and positive health outcomes in HIV-infected individuals. Virally suppressed individuals can also reduce the risk of HIV transmission to uninfected partners. Hence, adherence to ART has become both an HIV treatment and an HIV prevention strategy. However, achieving optimal ART adherence can be challenging, especially over the long term. It is increasingly important for clinicians and researchers to be abreast of the most recent developments in the field as new biomedical approaches to treatment emerge, and as guidelines for the use of pre-exposure prophylaxis (PrEP) are disseminated to providers serving HIV affected populations. Several reviews have described numerous ART adherence interventions that have been developed and/or tested with the most recent review including literature up to 2012. To augment the literature, we present a review of ART adherence interventions from 2013 – present. We included peer-reviewed journals as well as abstracts from two key conferences. PMID:25304006

    2012-05-01

    Black heterosexual men (BHM) are seldom mentioned in HIV prevention research, policy, and interventions, despite evidence that heterosexual contact is becoming the leading exposure category for BHM. The disparate effect of HIV/AIDS on BHM; the debunked "down low" myth; the contexts of BHM's lives in terms of disproportionate poverty, unemployment, and incarceration; and a growing empirical base linking these factors to increased HIV risk, underscore the need to prioritize HIV risk and prevention initiatives for BHM. We highlighted the structural contexts of HIV risk for BHM, and four community-based approaches to address HIV risk and prevention for BHM: (1) men's health programs; (2) workforce and postincarceration release programs; (3) linkages to women's prevention programs; and (4) faith-based initiatives.

    Women of the Laobe ethnic group and the Dimba, a traditional women's association, provide advice about sexuality and reproductive health in southern Senegal. Research was initiated in October 1992 by the Cheikh Anta Diop University to determine whether these women could also help in HIV/AIDS and STD prevention activities. The study investigated men's and women's knowledge, attitudes, beliefs, and practices (KABP) related to sexuality and HIV/AIDS/STDs in the community of Kolda; practices potentially increasing women's risk of HIV/STD infection; and possibilities for integrating HIV/STD prevention messages into the interactions which take place between the Laobe and Dimba groups and the Kolda community. The KABP study was a questionnaire administered to 250 men and 250 women of reproductive age representing five ethnic groups residing in Kolda. 11 men and 14 women older than age 40 participated in in-depth sexual life history interviews. The survey and interviews indicate that people in Kolda do not generally see a link between sexual relations and STD transmission. Instead, STDs are attributed to behaviors such as urinating, walking barefoot on the urine of an already-infected person, encountering a "bad wind", and being cursed. Women may be at increased risk of HIV infection through practices designed to enhance sexual pleasure, including the insertion of organic and mineral product into the vagina, and the cutting of bumps and warts in and around the vagina. Sexual practices, knowledge, prevention through the Laobe and Dimba, and outcome and follow-up are discussed. PMID:12346870

    2012-11-01

    In the past few years, the transdisciplinary field of HIV prevention has reached several milestones. Topically applied tenofovir gel provided significant protection from sexual transmission of HIV in a large-scale clinical trial and oral Truvada (emtricitabine/tenofovir disoproxil fumarate) was recently approved for preexposure prophylaxis (PrEP) following two successful clinical trials in men and women. These achievements are tempered by the disappointing results of other clinical trials, which highlight the complexities of prevention research. In this perspective, we discuss scientific and developmental gaps for topical chemoprophylaxis of the sexual transmission of HIV, which depends on the complex interactions between the pharmacokinetics and pharmacodynamics of drugs, formulation and delivery systems, anatomic site of transmission, and host mucosal immune defenses. Despite the considerable time and resources devoted to unraveling the initial steps in sexual transmission of HIV, current knowledge is based on animal models and human explanted tissue, which may not fully recapitulate what happens clinically. Understanding these events, including the role that sex hormones, semen, and mucosal secretions play in transmission, and the interplay between innate immunity, the mucosal environment, and drug efficacy is paramount. This drives some of the most pressing questions in the field. PMID:22966871

    Since the start of the HIV epidemic, community responses have been at the forefront of the response. Following the extraordinary expansion of global resources, the funding of community responses rose to reach at least US$690 million per year in the period 2005-2009. Since then, many civil society organisations (CSOs) have reported a drop in funding. Yet, the need for strong community responses is even more urgent, as shown by their role in reaching the Joint United Nations Programme on HIV/AIDS (UNAIDS) Fast-Track targets. In the case of antiretroviral treatment, interventions need to be adopted by most people at risk of HIV in order to have a substantial effect on the prevention of HIV at the population level. This paper reviews the published literature on community responses, funding and effectiveness. Additional funding is certainly needed to increase the coverage of community-based interventions (CBIs), but current evidence on their effectiveness is extremely mixed, which does not provide clear guidance to policy makers. This is especially an issue for adolescent girls and young women in Eastern and Southern Africa, who face extremely high infection risk, but the biomedical prevention tools that have been proven effective for the general population still remain pilot projects for this group. Research is especially needed to isolate the factors affecting the likelihood that interventions targeting this group are consistently successful. Such work could be focused on the community organisations that are currently involved in delivering gender-sensitive interventions. PMID:27399046

    Background Combination HIV prevention interventions that integrate efficacious behavioral and biomedical strategies offer the potential to reduce new HIV infections. Purpose We overview the efficacy data for three biomedical HIV prevention approaches: microbicides, pre-exposure prophylaxis (PrEP), and an HIV vaccination, review factors associated with differential acceptability and uptake of these methods, and suggest strategies to optimize the effectiveness and dissemination of combination HIV prevention approaches. Methods A narrative review was conducted highlighting key efficacy data for microbicides, PrEP, and an HIV vaccination and summarizing acceptability data for each of the three biomedical HIV prevention approaches. Recommendations for the integration and dissemination of combined behavioral and biomedical HIV prevention approaches are provided. Results To date, microbicides and an HIV vaccination have demonstrated limited efficacy for the prevention of HIV. However, PrEP has demonstrated efficacy in reducing HIV incident infections. A diverse array of factors influences both hypothetical willingness and actual usage of each biomedical prevention method. Conclusions Strategies to effectively integrate and evaluate combination HIV prevention interventions are urgently needed. PMID:25216985

    PubMed

    2013-07-01

    Regular condom use is the standard method for preventing HIV transmission during insertive intercourse. Effective treatment of infected individuals also reduces the risk of transmission. However, even when these preventive measures are used correctly, they are not completely reliable. Emtricitabine (a nucleoside) and tenofovir (a nucleotide) are HIV reverse transcriptase inhibitors. The combination of these 2 drugs has been authorised in the United States for the prevention of HIV-1 infection in adults at high risk, in combination with other preventive measures. Clinical evaluation is based mainly on two double-blind placebo-controlled trials. In a trial involving 2499 men or transgender women (born male) who have sex with men, conducted outside Europe, the incidence of infection was lower among patients treated with emtricitabine + tenofovir than with placebo (2.3 versus 4.3 per 100 person-years, p = 0.005). A subgroup analysis showed no added preventive effect of this treatment among condom users. Another trial including 4758 heterosexual couples in which only one partner was infected, conducted in Uganda and Kenya, showed a lower incidence of HIV infection in the emtricitabine + tenofovir group than in the placebo group after one year of treatment (0.50 versus 1.99 per 100 person-years). No statistically significant difference was found between the emtricitabine + tenofovir combination and tenofovir single-agent prophylaxis. Drug prevention showed no added efficacy in this trial among patients who regularly used condoms. Other trials conducted in Africa among heterosexuals favour the preventive efficacy of emtricitabine + tenofovir, except in one trial in which adherence appeared to be very poor. These trials did not identify any previously unknown adverse effects of emtricitabine + tenofovir. Tenofovir can cause kidney failure. Data from a US registry of pregnancies exposed to emtricitabine or tenofovir rule out any major risk of teratogenicity. In situations

    HIV is spread through direct contact with body fluids, such as blood, semen, vaginal fluids, and breast milk. HIV is not spread through everyday contact. People with HIV are not dangerous to the people they live with at home or in the community and with whom they have ordinary, non-sexual contact. Certain precautions should be taken, however, to minimize risk. First, personal items such as razors, toothbrushes or earrings, should not be shared. Latex gloves should be worn by uninfected family members when they may come into contact with bodily fluids, and the family members should always wash their hands with soap and water after touching blood and other fluids, even if gloves have been worn. The person with HIV can be protected by minimizing exposure to food-borne illnesses carried by raw or undercooked meat, eggs or unpasteurized milk; limiting contact with people who have colds, the flu or diarrhea; and avoiding contact with cages or litter boxes of pets. To help clarify sanitary measures, some frequently asked questions are answered. These questions address the safety of sharing food with HIV-infected people; chickenpox infection and emergence of shingles; prevention of CMV infection; toxoplasmosis and cats; spread of M. avium complex (MAC); and the safety of contact between HIV-infected people and infants.

    Despite increasing rates of HIV infection among young men who have sex with men (YMSM), only a minority participate in formal HIV prevention efforts. Semi-structured mixed-methods interviews were conducted with a diverse sample of YMSM (N = 100, M(age) = 25.0 years) in Los Angeles, California, to identify facilitators and barriers to participation in HIV prevention programs. Summative content analyses were used to evaluate transcribed field notes from these interviews. Results showed that 28.0 % of all participants had previously attended an HIV prevention program, and that 21.3 % of those who were also asked if they had ever participated in any research pertaining to HIV prevention had done so. A significantly higher percentage of those who had participated in HIV prevention programs had been tested for HIV in the past 6 months compared to those who had not (p < .05). The most frequently mentioned barriers to participation in such a program were being too busy to attend (12.0 %), not perceiving themselves to be at risk for HIV infection (14.0 %), and believing that they already knew everything they needed to know about HIV transmission (23.0 %). YMSM suggested that future interventions should use technology (e.g., the Internet, mobile devices), engage their social networks, and highlight HIV prevention as a means for community connection. Collectively, these results provide some explanations for why YMSM account for a minority of HIV prevention program participants and offer possible directions for future HIV prevention efforts that target YMSM.

    Three decades after the first government-funded HIV prevention campaign in 1985, gay and bisexual men (GBM) remain the population most at risk of infection in New Zealand. We review the major determinants of the elevated HIV risk for GBM, describe New Zealand's prevention response over the first 30 years, and summarise the public health record. HIV incidence among GBM is driven by the heightened biological efficiency of HIV transmission during unprotected anal intercourse, dense sexual partnering networks, and endemic HIV prevalence. Responses in New Zealand have emphasised evidence-based primary prevention by condom use, which were implemented in communities and supported by comprehensive public health action. New Zealand has a good international HIV prevention record among GBM, however HIV diagnosis rates are now higher than they were during the epidemic nadir of the late 1990s. Lessons from the first three decades must underpin future HIV control efforts. PMID:26913905

    To evaluate the awareness of HIV/AIDS prevention education, and the acceptance of HIV testing among residents on Likoma Island, Malawi, a cross-sectional, population-based study of 579 residents aged > or =15 years from seven villages on Likoma Island was conducted during July and August 2007. Most of the subjects studied could correctly answer questions about their awareness of AIDS and knowledge of the ways to reduce HIV transmission. Moreover, the proportion of respondents (65.8%) who possessed complete knowledge of HIV/AIDS prevention was greater than the national average. By contrast, condom utilization was slightly lower. Our results also showed that a high proportion of respondents (70.3%) had been HIV tested at any time, 93.5% of them voluntarily. Among correlated factors, females [adjusted odds ratio (AOR)=1.7, 95% CI 1.1-1.6] and polygamous individuals (AOR=3.3, 95% CI 1.5-7.0) were more likely to receive an HIV test. Past experience of being HIV tested was a strong predictor of possessing good knowledge and attitudes towards HIV/AIDS prevention. We conclude that antiretroviral treatment provided by Likoma District Hospital has led to the successful scale-up of HIV testing in Likoma Island and consequently improved the awareness of HIV/AIDS. However, the use of condoms remains largely unsupported, and there is therefore still a need to intensify general HIV/AIDS education on the island. PMID:19628236

    Self-efficacy is a critical element for HIV prevention, however little is known about the predictors of self-efficacy for HIV prevention among Hispanic women. In this cross-sectional study we assessed if age, living with a partner, employment status, HIV knowledge, self-esteem, and intimate partner violence (IPV) predicted self-efficacy for HIV prevention in 548 Hispanic women in South Florida who participated in a randomized controlled trial (SEPA). The majority of Hispanic women reported high levels of self-efficacy for HIV prevention. Women who were older, living with a partner, with less HIV knowledge, and a history of IPV reported significantly lower levels of self-efficacy for HIV prevention. HIV knowledge was the most important predictor of self-efficacy for HIV prevention. Employment was not a significant predictor of self-efficacy for HIV prevention. Predictors identified in the study can be used to identify high-risk Hispanic women who are in need of HIV prevention interventions. PMID:22795758

    Objectives. We examined the relationships between mobility characteristics and sexual risk behaviors among male and female migrant market vendors in Almaty, Kazakhstan. Methods. Participants completed a structured interview covering sociodemographics, mobility characteristics, sexual behaviors, and biomarkers for HIV, HCV, and syphilis. We used multivariate analyses to examine associations between mobility patterns and HIV risks after adjusting for sociodemographics. Results. Longer duration of a participant's last trip outside Almaty increased the odds of reporting multiple sexual partners. More frequent travel to visit family or friends was associated with multiple sexual partners and unprotected sex with steady partners. More frequent travel to buy goods in the past year was associated with multiple sexual partners. Men who traveled more often to buy goods were more likely to have purchased sex within the previous 90 days. Conclusions. Relationships between mobility patterns and sexual risk behaviors underscore the need for HIV-prevention strategies targeting the specific transmission dynamics that migrant vendors are likely to present.

    Purpose The Adolescent Medicine Trials Network Protocol 113 (ATN113) is an open-label, multi-site demonstration project and phase II safety study of HIV pre-exposure prophylaxis with 15-17 year old young men who have sex with men that requires adolescent consent for participation. The purpose of this study was to examine factors related to the process by which Institutional Review Boards (IRBs) and researchers made decisions regarding whether to approve and implement ATN113, so as to inform future biomedical HIV prevention research with high-risk adolescent populations. Methods Participants included seventeen researchers at thirteen sites in twelve states considering ATN113 implementation. Qualitative descriptive methods were used. Data sources included interviews and documents generated during the initiation process. Results A common process for initiating ATN113 emerged, and informants described how they identified and addressed practical, ethical and legal challenges that arose. Informants described the process as responding to the protocol, preparing for IRB submission, abstaining from or proceeding with submission, responding to IRB concerns and reacting to the outcomes. A complex array of factors impacting approval and implementation were identified; and ATN113 was ultimately implemented in 7 of 13 sites. Informants also reflected on lessons learned that may help inform future biomedical HIV prevention research with high-risk adolescent populations. Conclusions The results illustrate factors for consideration in determining whether to implement such trials, demonstrate that such protocols have the potential to be approved, and highlight a need for clearer standards regarding biomedical HIV prevention research with high-risk adolescent populations.

    The public sector supports most HIV/AIDS prevention and care activities in developing countries, with significant funding provided by the US Agency for International Development, the Overseas Development Authority, the European Community, and international banking institutions such as the World Bank. Local nongovernmental organizations (NGOs) and international private voluntary organizations (PVOs) implement many of the grassroots prevention and care efforts in developing countries, but often require support from donor agencies. While the private commercial sector has played a minor role in supporting HIV/AIDS prevention and care efforts, a number of local and multinational companies are beginning to recognize the importance of protecting their workers from HIV infection. These companies are motivated by a sense of moral obligation and/or view HIV/AIDS prevention as a cost-effective investment. Mainly affecting the most economically productive age groups, the HIV/AIDS epidemic will have a significant impact upon private industry. Workplace-based prevention programs and policies, private sector resources for HIV/AIDS prevention and care, how HIV/AIDS programs can benefit from the private sector's experience in commercial service delivery, research and development, and corporate direct cash and in-kind contributions to government and NGO HIV/AIDS prevention activities are discussed. The AIDS Control and Prevention (AIDSCAP) Project's Businesses Managing AIDS Project helps owners and managers understand the potential impact of HIV/AIDS upon their businesses and the benefits of HIV/AIDS prevention.

    Abstract HIV transmission is a major health concern. Global efforts are necessary to control the spread of infection. International collaborative studies in countries with high rates of new infections are essential for increasing knowledge on the behavioral, social, and biomedical aspects of HIV/AIDS and HIV transmission. Statistics indicate a growing HIV epidemic in Russia. There are alarming proportions of new cases attributed to heterosexual contact, and HIV is increasingly affecting people in the general population who are not part of any traditional high-risk group. Despite recent advances in HIV prevention, data on effective behavioral prevention approaches are limited. There is minimal evidence to suggest which types of prevention will be effective in reducing the risk for HIV transmission among people at risk in the general population. This article presents a review and discussion of an international research seminar, HIV Prevention Research: Evidence-Based Behavioral Approaches. Local and international interdisciplinary researchers gathered for the purposes of exchanging research results and information about ongoing studies, identifying gaps in knowledge, and discussing promising prevention strategies. The overarching goal was to advance HIV prevention research through scientific integration. The seminar provided an excellent platform for building research capacity in interdisciplinary HIV research in Russia and integrating research efforts with the international research community to contribute to HIV prevention research throughout the world.

  8. "Typhoid Mary" and "HIV Jane": responsibility, agency and disease prevention.

    PubMed

    Chan, Kit Yee; Reidpath, Daniel D

    2003-11-01

    The construction of disease risks as knowable, calculable and preventable in dominant social science and public health discourses has fostered a certain kind of logic about individual risk and the responsibility for infection. Disease control measures that have developed out of this logic typically fail to recognise the socio-structural roots of many high-risk behaviours that are linked to the spread of infection. Instead, they hold the disease carrier responsible for managing his/her own risk of infection of others, and rely on constraining the agency of the carrier (e.g. by constraining movement, contact or occupation). In occupations associated with a high risk of infection, the idea of responsibility of the actor implicitly raises issues of "professional responsibility". Using the case of "Typhoid Mary" and a hypothetical case of "HIV Jane", this paper explores some of the problems with making sex workers responsible for the prevention of HIV transmission. It argues that for the notion of "responsibility" to make any sense, the HIV-positive person must be in a position to exercise responsibility, and for this they must have agency. PMID:14708397

    Social networking technologies are influential among men who have sex with men (MSM) and may be an important strategy for HIV prevention. We conducted focus groups with HIV positive and negative participants. Almost all participants used social networking sites to meet new friends and sexual partners. The main obstacle to effective HIV prevention campaigns in social networking platforms was stigmatization based on homosexuality as well as HIV status. Persistent stigma associated with HIV status and disclosure was cited as a top reason for avoiding HIV-related conversations while meeting new partners using social technologies. Further, social networking sites have different social etiquettes and rules that may increase HIV risk by discouraging HIV status disclosure. Overall, successful interventions for MSM using social networking technologies must consider aspects of privacy, stigma, and social norms in order to enact HIV reduction among MSM. PMID:26241381

    Background After the first two cases of locally-acquired HIV infection were recognized in Chuuk State, Federated States of Micronesia (FSM), a public health response was initiated. The purpose of the response was to assess the need for HIV education and prevention services, to develop recommendations for controlling further spread of HIV in Chuuk, and to initiate some of the prevention measures. Methodology/Principal Findings A public health team conducted a survey and rapid HIV testing among a sample of residents on the outer islands in Chuuk. Local public health officials conducted contact tracing and testing of sex partners of the two locally-acquired cases of HIV infection. A total of 333 persons completed the survey. The majority knew that HIV is transmitted through unprotected sexual contact (81%), injection drug use (61%), or blood transfusion (64%). Sexual activity in the past 12 months was reported among 159 participants, including 90 females and 69 males. Compared to women, men were more likely to have had multiple sex partners, to have been drunk during sex, but less likely to have used a condom in the past 12 months. The two men with locally acquired HIV infection had unprotected anal sex with a third Chuukese man who likely contracted HIV while outside of Chuuk. All 370 persons who received voluntary, confidential HIV counseling and testing had HIV negative test results. Conclusions/Significance Despite the low HIV seroprevalence, risky sexual behaviors in this small isolated population raise concerns about the potential for rapid spread of HIV. The lack of knowledge about risks, along with stigmatizing attitudes towards persons infected with HIV and high risk sexual behaviors indicate the need for resources to be directed toward HIV prevention in Chuuk and on other Pacific Islands.

    In the past 25 years, the field of HIV prevention research has been transformed repeatedly. Today, effective HIV prevention requires a combination of behavioral, biomedical, and structural intervention strategies. Risk of transmitting or acquiring HIV is reduced by consistent male and female-condom use, reductions in concurrent and/or sequential sexual and needle-sharing partners, male circumcision, and treatment with antiretroviral medications. At least 144 behavioral prevention programs have been found effective in reducing HIV transmission acts; however, scale up of these programs has not occurred outside of the United States. A series of recent failures of HIV-prevention efficacy trials for biomedical innovations such as HIV vaccines, treating herpes simplex 2 and other sexually transmitted infections, and diaphragm and microbicide barriers highlights the need for behavioral strategies to accompany biomedical strategies. This challenges prevention researchers to reconceptualize how cost-effective, useful, realistic, and sustainable prevention programs will be designed, delivered, tested, and diffused. The next generation of HIV prevention science must draw from the successes of existing evidence-based interventions and the expertise of the market sector to integrate preventive innovations and behaviors into everyday routines.

    Given the inordinate burden of HIV illness borne by African American men, investigations of HIV prevention and care in this population are urgently needed. In this qualitative study, a sample of 20 HIV-infected African American men participated in two focus groups in which they exchanged experiences and ideas about living with HIV. They shared details about how they were personally impacted by HIV, and together they constructed a perspective on the larger societal context in which the HIV infection rate among African American men continues unabated. The men focused on growing complacency about HIV/AIDS in the United States, underfunding of supports and services, stigmas operative in African American communities, and differential care based on race, gender, and diagnosis. They saw opportunity in personal strategies that help individual men infected with HIV to take a more empowered stance to deal with the disease and improve their health but looked for changes undertaken by African Americans at the community level to make a real difference in the epidemic. Their vision included enhanced support for HIV prevention and care from influential community institutions like Black churches, more open dialogue about drugs and sexual behavior, and capacity-building for families whose members are HIV-infected or at risk for HIV.

    Social marketing involves applying marketing principles to promote social goods. In the context of health behavior, it has been used successfully to reduce alcohol-related car crashes, smoking among youths, and malaria transmission, among other goals. Features of social marketing, such as audience segmentation and repeated exposure to prevention messages, distinguish it from traditional health promotion programs. A recent review found 8 of 10 rigorously evaluated social marketing interventions responsible for changes in HIV-related behavior or behavioral intentions. We studied 479 injection drug users to evaluate a community-based social marketing campaign to reduce injection risk behavior among drug users in Sacramento, California. Injecting drugs is associated with HIV infection in more than 130 countries worldwide. PMID:20724686

    Adolescents are the only age group with growing AIDS-related morbidity and mortality in Eastern and Southern Africa, making HIV prevention research among this population an urgent priority. Structural deprivations are key drivers of adolescent HIV infection in this region. Biomedical interventions must be combined with behavioural and social interventions to alleviate the socio-structural determinants of HIV infection. There is growing evidence that social protection has the potential to reduce the risk of HIV infection among children and adolescents. This research combined expert consultations with a rigorous review of academic and policy literature on the effectiveness of social protection for HIV prevention among children and adolescents, including prevention for those already HIV-positive. The study had three goals: (i) assess the evidence on the effectiveness of social protection for HIV prevention, (ii) consider key challenges to implementing social protection programmes that promote HIV prevention, and (iii) identify critical research gaps in social protection and HIV prevention, in Eastern and Southern Africa. Causal pathways of inequality, poverty, gender and HIV risk require flexible and responsive social protection mechanisms. Results confirmed that HIV-inclusive child-and adolescent-sensitive social protection has the potential to interrupt risk pathways to HIV infection and foster resilience. In particular, empirical evidence (literature and expert feedback) detailed the effectiveness of combination social protection particularly cash/in-kind components combined with "care" and "capability" among children and adolescents. Social protection programmes should be dynamic and flexible, and consider age, gender, HIV-related stigma, and context, including cultural norms, which offer opportunities to improve programmatic coverage, reach and uptake. Effective HIV prevention also requires integrated social protection policies, developed through strong national

    HIV is still a major health problem in developing countries. Even though high HIV-risk-taking behaviors have been reported in African fishing villages, local distribution patterns of HIV infection in the communities surrounding these villages have not been thoroughly analyzed. The objective of this study was to investigate the geographical distribution patterns of HIV infection in communities surrounding African fishing villages. In 2011, we applied age- and sex-stratified random sampling to collect 1,957 blood samples from 42,617 individuals registered in the Health and Demographic Surveillance System in Mbita, which is located on the shore of Lake Victoria in western Kenya. We used these samples to evaluate existing antibody detection assays for several infectious diseases, including HIV antibody titers. Based on the results of the assays, we evaluated the prevalence of HIV infection according to sex, age, and altitude of participating households. We also used Kulldorff's spatial scan statistic to test for HIV clustering in the study area. The prevalence of HIV at our study site was 25.3%. Compared with the younger age group (15-19 years), adults aged 30-34 years were 6.71 times more likely to be HIV-positive, and the estimated HIV-positive population among women was 1.43 times larger than among men. Kulldorff's spatial scan statistic detected one marginally significant (P = 0.055) HIV-positive and one significant HIV-negative cluster (P = 0.047) in the study area. These results suggest a homogeneous HIV distribution in the communities surrounding fishing villages. In addition to individual behavior, more complex and diverse factors related to the social and cultural environment can contribute to a homogeneous distribution pattern of HIV infection outside of African fishing villages. To reduce rates of transmission in HIV-endemic areas, HIV prevention and control programs optimized for the local environment need to be developed. PMID:26862764

    When HIV prevention targets risk and vulnerability, it focuses on individual agency and social structures, ignoring the centrality of community in effective HIV prevention. The neoliberal concept of risk assumes individuals are rational agents who act on information provided to them regarding HIV transmission. This individualistic framework does not recognize the communities in which people act and connect. The concept of vulnerability on the other hand acknowledges the social world, but mainly as social barriers that make it difficult for individuals to act. Neither approach to HIV prevention offers understanding of community practices or collective agency, both central to success in HIV prevention to date. Drawing on examples of the social transformation achieved by community action in Australia and Brazil, this article focuses on this middle ground and its role in effective HIV prevention.

    Researchers and sponsors are required to assist HIV prevention trial participants to remain HIV-uninfected by ensuring access to prevention services. Ethics guidelines require that these HIV risk-reduction services be state of the art. This and related ethics recommendations have been intensely debated. This descriptive study aimed to identify actual HIV prevention practices for two HIV vaccine trials at five South African sites, to explore whether actual practices meet guideline recommendations and to discuss implications for practices and ethics guidelines. Practices were examined through a review of site documents and interviews with site staff and network representatives, as well as community advisory board and research ethics committee representatives. A thematic analysis of HIV prevention practices, perspectives and perceived challenges was undertaken. Findings indicated that there was a high degree of correspondence between actual practices in South African HIV vaccine trials and guideline recommendations. Key challenges for implementing prevention services were identified as partnerships, provider-promotion of services and participant uptake of services. Practices deviated most from guidelines with regard to the description of prevention plans in informed consent forms. Recommendations are made for both practices and ethics guidelines. PMID:25031609

    Nigeria is second in the world for the number of people with HIV and has a high rate of mother-to-child transmission (MTCT). Over 60% of births in Nigeria occur outside of health care facilities, and because of this, Traditional Birth Attendants (TBAs) play a significant role in maternal and child health. It is important that TBAs be knowledgeable about HIV prevention. The purpose of this study was to determine the impact of HIV testing and counseling (HTC) knowledge on the HIV prevention practices among TBAs in Nigeria. Five hundred TBAs were surveyed. Chi-square and logistic regression were used to assess differences in HIV prevention practices between TBAs with and without HTC knowledge. TBAs with HTC knowledge are significantly more likely to engage in HIV prevention practices than TBAs without HTC. Prevention practices included: wearing gloves during delivery (p < 0.01), sterilization of delivery equipment (p < 0.01), participation in blood safety training (p < 0.01), and disposal of sharps (p < 0.01). As long as a high percent of births occur outside health care facilities in Nigeria, there will be a need for TBAs. Providing TBAs with HTC training increases HIV prevention practices and can be a key to improve maternal and child health. PMID:25674783

    Background and objectives Heterosexual HIV-1 serodiscordant couples are increasingly recognized as an important source of new HIV-1 infections in sub-Saharan Africa. A simple risk assessment tool could be useful for identifying couples at highest risk for HIV-1 transmission. Methods Using data from three prospective studies of HIV-1 serodiscordant couples from seven African countries and standard methods for development of clinical prediction rules, we derived and validated a risk scoring tool developed from multivariate modeling and composed of key predictors for HIV-1 risk that could be measured in standard research and clinical settings. Results The final risk score included age of the HIV-1 uninfected partner, married and/or cohabiting partnership, number of children, unprotected sex, uncircumcised male HIV-1 uninfected partner, and plasma HIV-1 RNA in the HIV-1 infected partner. The maximum risk score was 12, scores ≥5 were associated with an annual HIV-1 incidence of >3%, and couples with a score ≥6 accounted for only 28% of the population but 67% of HIV-1 transmissions. The area under the curve for predictive ability of the score was 0.74 (95% CI 0.70–0.78). Internal and external validation showed similar predictive ability of the risk score, even when plasma viral load was excluded from the risk score. Conclusions A discrete combination of clinical and behavioral characteristics defines highest-risk HIV-1 serodiscordant couples. Discriminating highest-risk couples for HIV-1 prevention programs and clinical trials using a validated risk score could improve research efficiency and maximize the impact of prevention strategies for reducing HIV-1 transmission.

    Mobile populations are at increased risk for HIV infection. Exposure to HIV prevention messages at all phases of the migration process may help decrease im/migrants' HIV risk. We investigated levels of exposure to HIV prevention messages, factors associated with message exposure, and the association between exposure to prevention messages and HIV testing behavior among Mexican im/migrants at different phases of the migration process. We conducted a cross-sectional, probability survey of Mexican im/migrants (N = 3,149) traveling through the border city of Tijuana, Mexico. The results indicate limited exposure to prevention messages (57-75%) and suboptimal last 12-month HIV testing rates (14-25%) across five migration phases. Compared to pre-departure levels (75%), exposure to messages decreases at all post-departure migration phases (57-63%, p < .001). In general, exposure to prevention messages is positively associated with greater odds of HIV testing at the pre-departure, destination, and interception phases. Binational efforts need to be intensified to reach and deliver HIV prevention to Mexican im/migrants across the migration continuum. PMID:26595267

    Statistics clearly show an unmet need for highly effective contraception, especially in less developed countries. Many of these countries are at the core of the HIV/AIDS epidemic and show very high prevalence rates for other sexually transmitted infections (STIs) such as that caused by HSV-2. A woman at risk of unintended pregnancy due to unprotected intercourse is also at risk for HIV/STI. Owing to their causative interrelationship, combining protection against these conditions will result in enhanced prevention and health benefits. Existing multipurpose prevention modalities such as condoms and physical barriers, albeit efficacious, face cultural hurdles that have so far hindered their widespread use. Success has recently been demonstrated in large clinical trials, demonstrating proof of concept of microbicides in reducing the incidence of HIV-1 and HSV-2 among at-risk populations. The challenge heretofore is to refine these products to make them more potent, convenient, accessible, and acceptable. Potent antiviral drugs released topically in the female reproductive tract by innovative delivered systems and formulations will provide safe, effective, and acceptable multipurpose prevention tools. This paper provides an overview of existing and novel approaches to multipurpose prevention strategies. PMID:21836811

    Background Biomedical HIV prevention trials enroll sexually active women at risk of HIV and often discontinue study product during pregnancy. We assessed risk factors for pregnancy and HIV acquisition, and the effect of pregnancy on time off study drug in HPTN 039. Methods 1358 HIV negative, HSV-2 seropositive women from South Africa, Zambia, and Zimbabwe were enrolled and followed for up to 18 months. Results 228 pregnancies occurred; time off study drug due to pregnancy accounted for 4% of woman-years of follow-up among women. Being pregnant was not associated with increased HIV risk (hazard ratio [HR] 0.64 95% CI [0.23, 1.80], p=0.40). However, younger age was associated with increased risk for both pregnancy and HIV. There was no association between condom use as a sole contraceptive and reduced pregnancy incidence; hormonal contraception was not associated with increased HIV risk. Bacterial vaginosis at study entry was associated with increased HIV risk (HR 2.03, p=0.02). Conclusions Pregnancy resulted in only a small amount of woman-time off study drug. Young women are at high risk for HIV and are an appropriate population for HIV prevention trials but also have higher risk of pregnancy. Condom use was not associated with reduced incidence of pregnancy. PMID:19838129

    2013-01-01

    With 33 million people living with human immunodeficiency virus (HIV) worldwide and 2.7 million new infections occurring annually, additional HIV prevention and treatment efforts are urgently needed. However, available resources for HIV control are limited and must be used efficiently to minimize the future spread of the epidemic. We develop a model to determine the appropriate resource allocation between expanded HIV prevention and treatment services. We create an epidemic model that incorporates multiple key populations with different transmission modes, as well as production functions that relate investment in prevention and treatment programs to changes in transmission and treatment rates. The goal is to allocate resources to minimize R0, the reproductive rate of infection. We first develop a single-population model and determine the optimal resource allocation between HIV prevention and treatment. We extend the analysis to multiple independent populations, with resource allocation among interventions and populations. We then include the effects of HIV transmission between key populations. We apply our model to examine HIV epidemic control in two different settings, Uganda and Russia. As part of these applications, we develop a novel approach for estimating empirical HIV program production functions. Our study provides insights into the important question of resource allocation for a country's optimal response to its HIV epidemic and provides a practical approach for decision makers. Better decisions about allocating limited HIV resources can improve response to the epidemic and increase access to HIV prevention and treatment services for millions of people worldwide.

    2013-01-01

    Background As each HIV-infected individual represents a breakdown of HIV primary prevention measures, formative data from representative individuals living with HIV can help shape future primary prevention interventions. Little is known about sexual behaviours and other transmission risk factors of high-risk group members who are already HIV-infected in Chennai, India. Methods Semi-structured qualitative interviews were conducted with 27 HIV-infected individuals representing each high-risk group in Chennai (five men who have sex with men (MSM), five female commercial sex workers (CSW), four truckers and other men who travel for business, four injecting drug users (IDU), five married male clients of CSW, and four wives of CSW clients, MSM, truckers, and IDU). Results Themes relevant to HIV primary prevention included: (1) HIV diagnosis as the entry into HIV education and risk reduction, (2) reluctance to undergo voluntary counselling and testing, (3) gender and sexual roles as determinants of condom use, (4) misconceptions about HIV transmission, and (5) framing and accessibility of HIV education messages. Conclusions These qualitative data can be used to develop hypotheses about sexual risk taking in HIV-infected individuals in South India, inform primary prevention intervention programs, and improve primary prevention efforts overall.

  10. HIV prevention, structural change and social values: the need for an explicit normative approach

    2012-01-01

    Background The fact that HIV prevention often deals with politicised sexual and drug taking behaviour is well known, but structural HIV prevention interventions in particular can involve alteration of social arrangements over which there may be further contested values at stake. As such, normative frameworks are required to inform HIV prevention decisions and avoid conflicts between social goals. Methods This paper provides a conceptual review and discussion of the normative issues surrounding structural HIV prevention strategies. It applies political and ethical concepts to explore the contested nature of HIV planning and suggests conceptual frameworks to inform future structural HIV responses. Results HIV prevention is an activity that cannot be pursued without making value judgements; it is inherently political. Appeals to health outcomes alone are insufficient when intervention strategies have broader social impacts, or when incidence reduction can be achieved at the expense of other social values such as freedom, equality, or economic growth. This is illustrated by the widespread unacceptability of forced isolation which may be efficacious in preventing spread of infectious agents, but conflicts with other social values. Conclusions While no universal value system exists, the capability approach provides one potential framework to help overcome seeming contradictions or value trade-offs in structural HIV prevention approaches. However, even within the capability approach, valuations must still be made. Making normative values explicit in decision making processes is required to ensure transparency, accountability, and representativeness of the public interest, while ensuring structural HIV prevention efforts align with broader social development goals as well.

    There is no viable substitute for re-energizing, funding and supporting culturally attuned, locally staffed HIV advocacy and prevention programmes, especially in resource poor settings. The evidence that such interventions are effective remains compelling; and although the cost implications are not negligible, the medium to long-term outcomes must be regarded not as complementary, but as integral, to biomedical interventions. The success of the anti-retroviral drugs upscale has enabled a noticeable improvement in AIDS related morbidity and mortality in the recent years; yet the underlying dynamics of the epidemic remains undetermined by the rate at which new infections are taking place in relation to the number of AIDS deaths. While the rate of new HIV infections is stabilising in some of the hardest hit countries, it remains far too high and the future cost of maintaining an ever-expanding pool of people reliant on daily drugs for survival is unsustainable. Countries must exercise caution in continuing to focus on treatment as a ‘quick fix’ to end AIDS as a public health concern. HIV is a socially culturally induced crisis and, as such, a variety of measures are needed simultaneously to appeal to different people, groups and circumstances. PMID:27347272

    The prevalence of HIV/AIDS infection among prisoners is 3 to 4 times higher than in the U.S. population. Given that one in seven HIV-positive Americans pass through a correctional facility every year, the criminal justice system is in an ideal position to aggressively implement effective HIV education, treatment, and prevention. This study examines barriers to the effective delivery of these services and evaluates differences in risk perception among nearly 600 female and male inmates. The results underscore gender differences in Perceived Risk of Seroconversion and Exposure to HIV Education, suggesting that jails should implement gender-specific HIV prevention programming.

  14. Innate immunity against HIV: a priority target for HIV prevention research

    PubMed Central

    2010-01-01

    This review summarizes recent advances and current gaps in understanding of innate immunity to human immunodeficiency virus (HIV) infection, and identifies key scientific priorities to enable application of this knowledge to the development of novel prevention strategies (vaccines and microbicides). It builds on productive discussion and new data arising out of a workshop on innate immunity against HIV held at the European Commission in Brussels, together with recent observations from the literature. Increasing evidence suggests that innate responses are key determinants of the outcome of HIV infection, influencing critical events in the earliest stages of infection including the efficiency of mucosal HIV transmission, establishment of initial foci of infection and local virus replication/spread as well as virus dissemination, the ensuing acute burst of viral replication, and the persisting viral load established. They also impact on the subsequent level of ongoing viral replication and rate of disease progression. Modulation of innate immunity thus has the potential to constitute a powerful effector strategy to complement traditional approaches to HIV prophylaxis and therapy. Importantly, there is increasing evidence to suggest that many arms of the innate response play both protective and pathogenic roles in HIV infection. Consequently, understanding the contributions made by components of the host innate response to HIV acquisition/spread versus control is a critical pre-requisite for the employment of innate immunity in vaccine or microbicide design, so that appropriate responses can be targeted for up- or down-modulation. There is also an important need to understand the mechanisms via which innate responses are triggered and mediate their activity, and to define the structure-function relationships of individual innate factors, so that they can be selectively exploited or inhibited. Finally, strategies for achieving modulation of innate functions need to be

    Ethnic churches attended by first generation Chinese immigrants are uniquely positioned to address emerging HIV prevention and care needs within the Chinese community at-large. Efforts to develop faith-based HIV programs necessitate identifying how HIV intersects with the sinicization of Christianity within Chinese churches. This paper will review the process of contextualizing HIV within theological and cultural frameworks that are meaningful for ethnic Chinese church leaders and members. The authors specifically propose two points of integration between public health and ecclesial functions: (1) HIV stigma-mitigation initiatives as informed by Christo-centric teachings of compassion and justice, and (2) HIV prevention and care reframed as social responsibility and informed by the Christian tradition of evangelism. Systems and practices that hinder and promote the involvement of Chinese churches in HIV prevention, care, and stigma-reduction will be discussed. PMID:23483037

    We conducted a systematic review of couple-based HIV biobehavioral (skills-building, VCT, and adherence) and biomedical (ART, circumcision) prevention and intervention studies designed to reduce sexual-and drug-risk behaviors and HIV transmission and acquisition. Of the 11,162 papers identified in the search, 93 peer-reviewed papers met the inclusion criteria and yielded a total of 33 studies conducted globally. Biobehavioral couple-based prevention and intervention studies have been efficacious in reducing sexual- and drug-risk behaviors, increasing access to HIV testing and care, and improving adherence. Biomedical couple-based studies were found to reduce HIV incidence among HIV-negative sex partners and viral load among HIV-positive partners. Despite much progress, couple-based HIV prevention and intervention studies remain limited; a number of methodological gaps exist and studies focusing on MSM, people who inject drugs, and sex workers are scarce.

    2015-01-01

    HIV counseling and voluntary testing during antenatal care have been proven to reduce the risk of HIV transmission from mother to child, through increasing knowledge about safe behaviors, ascertaining HIV status and increasing coverage of effective antiretroviral regimens. However, it remains that, in developing countries where 95 % of mother-to-child HIV transmissions (MTCT) take place, such interventions are not widely accessible or available. Using a nationally representative cross-sectional household survey, the present study aimed to examine individual- and contextual-level influences on the receipt of HIV pre-test counseling and uptake of HIV testing during the antenatal care period in Swaziland, a country highly burdened by HIV/AIDS. The study sample was restricted to women aged 15-49 years with a live birth in the past five years preceding the survey and who received antenatal care for the most recent birth. The findings of this study indicated that only 62 % of women received pre-test counseling for the prevention of MTCT and no more than 56 % of women consented to be tested for HIV during antenatal care. The multilevel regression analysis revealed that the likelihood of receiving HIV pre-test counseling increases significantly with higher parity, education level, household wealth and antenatal visits while it is lower in areas where poverty is pervasive (OR = 0.474) and in rural regions (OR = 0.598) as well. Beyond all the significant predictors, undergoing pre-test counseling has emerged as an important determinant of HIV testing. Receiving pre-test counseling increases the odds of accepting an HIV test by 77 %. Evidence from this analysis underscores bottlenecks and challenges that persist in increasing the need for and uptake of HIV preventive and treatment services to stop new HIV infections among children.

    subgroup analyses among the observational studies to see if the effect of ART on prevention of HIV differed by the index partner’s CD4 cell count. Among couples in which the infected partner had ≥350 CD4 cells/µL, we estimated a rate ratio of 0.12 [95% CI 0.01, 1.99]. In this subgroup, there were 247 transmissions in untreated couples and 30 in treated couples. Authors’ conclusions ART is a potent intervention for prevention of HIV in discordant couples in which the index partner has ≤550 CD4 cells/µL. A recent multicentre RCT confirms the suspected benefit seen in earlier observational studies and reported in more recent ones. Questions remain about durability of protection, the balance of benefits and adverse events associated with earlier therapy, long-term adherence and transmission of ART-resistant strains to partners. Resource limitations and implementation challenges must also be addressed. Counselling, support, and follow up, as well as mutual disclosure, may have a role in supporting adherence, so programmes should be designed with these components. In addition to ART provision, the operational aspects of delivering such programmes must be considered. PMID:23633367

To explore important and changeable determinants of condom use and inspect effective and feasible methods to increase condom use for the target population, we conducted a three-round web-based Delphi study among a panel of 62 experts between October 2012 and March 2013. The panelists were purposely selected using a stepwise procedure to represent topic-related areas of expertise. The response rate per round ranges from 21% to 81%. The panelists identified 19 possible determinants of condom use and reported 16 intervention methods they considered successful. They agreed that attitude towards condom use was the most important and changeable determinant, while applying behavioral theory, increasing sexual education and condom access, performing worksite health promotion, detecting risk factors, and working closely with relevant organizations and the government were effective and feasible methods to increase condom use among internal migrants in China. In conclusion, results of this study highlight the importance of attitude in changing condom use and underscore the need to apply behavior theory and integrate multiple educational approaches for developing behavioral HIV prevention interventions targeting internal migrants in China.

    Successes in preventing HIV transmission among substance using populations have focused primarily among injection drug users, which have produced measurable reductions in HIV incidence and prevalence. By contrast, the majority of substances used worldwide are administered by non-injectable means, and there is a dearth of HIV prevention interventions that target non-injecting substance users. Increased surveillance of trends in substance use, especially cocaine (including crack) and methamphetamine in addition to new and emerging substances (e.g., synthetic cannabinoids, cathinones and other amphetamine analogs) are needed to develop and scale-up effective and robust interventions for populations at risk for HIV-transmission via sexual behaviors related to non-injection substance use. Strategies are needed that address unique challenges to HIV prevention for substance users who are HIV-infected and those who are HIV- uninfected and at high risk. We propose a research agenda that prioritizes: (1) ) combination HIV prevention strategies in substance users; (2) behavioral HIV prevention programs that reduce sexual transmission behaviors in non-treatment seeking individuals; (3) medical and/or behavioral treatments for substance abuse that reduce/eliminate substance-related sexual transmission behaviors; and (4) structural interventions to reduce HIV incidence.

    Background Patients with Tuberculosis (TB) are a vulnerable group for acquiring HIV infection. Therefore, countries with a concentrated HIV epidemic and high prevalence of TB should provide adequate information about HIV prevention to TB patients. Methods We conducted a cross-sectional study to evaluate the level of knowledge on HIV prevention and transmission among newly diagnosed TB patients in Lima, Peru. The survey evaluated knowledge about HIV infection and prevention and was administered before HIV counseling and blood sampling for HIV testing were performed. Results A total of 171 TB patients were enrolled; mean age was 31.1 years, 101 (59%) were male. The overall mean level of knowledge of HIV was 59%; but the specific mean level of knowledge on HIV transmission and prevention was only 33.3% and 41.5%, respectively. Age and level of education correlated with overall level of knowledge in the multivariate model (P-value: 0.02 and <0.001 respectively). Conclusions The study shows inadequate levels of knowledge about HIV transmission and prevention among newly-diagnosed TB patients in this setting, and underscores the need for implementing educational interventions in this population.

    People with HIV who are released from custody frequently do not maintain the viral suppression and other health benefits achieved while incarcerated. This study was conducted to provide preliminary evidence of efficacy of an intervention to reduce HIV risk behaviors and increase use of HIV medical services following release from custody. People with HIV were recruited from San Francisco County jails, San Quentin State Prison and the California Medical Facility (Vacaville, CA), and randomly assigned to the "standard of care" or POST intervention. POST consisted of 4 sessions pre-release and 2 sessions post-release, focusing on HIV prevention and access to care. Behavioral data were obtained for the 3 months before incarceration and 3 months after release. Although POST participants reported a statistically significant increase in receiving health care at HIV clinics (62.5-84.4 %), there were no significant differences between the POST and control participants with respect to any primary outcomes.

Semi-structured interviews were conducted with HIV-infected men who were currently receiving primary HIV health care. Positive peer counselor themes included shared experiences and para-professional. Positive themes specific to the PCM relationships included were provision of resources and professional skills and knowledge. Common themes identified across both peer and PCM counselor relationships were creating a comfortable environment, non-judgmental stance, and rapport building/communication skills. Recommendations for HIV secondary prevention interventions are presented. PMID:23710120

    HIV prevention trials have demonstrated the effectiveness of a number of behavioral and biomedical interventions. HIV prevention packages are combinations of interventions and offer potential to significantly increase the effectiveness of any single intervention. Estimates of the effectiveness of prevention packages are important for guiding the development of prevention strategies and for characterizing effect sizes before embarking on large scale trials. Unfortunately, most research to date has focused on testing single interventions rather than HIV prevention packages. Here we report the results from agent-based modeling of the effectiveness of HIV prevention packages for men who have sex with men (MSM) in South Africa. We consider packages consisting of four components: antiretroviral therapy for HIV infected persons with CD4 count <350; PrEP for high risk uninfected persons; behavioral interventions to reduce rates of unprotected anal intercourse (UAI); and campaigns to increase HIV testing. We considered 163 HIV prevention packages corresponding to different intensity levels of the four components. We performed 2252 simulation runs of our agent-based model to evaluate those packages. We found that a four component package consisting of a 15% reduction in the rate of UAI, 50% PrEP coverage of high risk uninfected persons, 50% reduction in persons who never test for HIV, and 50% ART coverage over and above persons already receiving ART at baseline, could prevent 33.9% of infections over 5 years (95% confidence interval, 31.5, 36.3). The package components with the largest incremental prevention effects were UAI reduction and PrEP coverage. The impact of increased HIV testing was magnified in the presence of PrEP. We find that HIV prevention packages that include both behavioral and biomedical components can in combination prevent significant numbers of infections with levels of coverage, acceptance and adherence that are potentially achievable among MSM in

    Naltrexone is an antagonist that binds tightly to μ-opioid receptors and blocks the subjective and analgesic effects of opioids. It does not produce physiologic dependence and precipitates withdrawal if administered to an opioid dependent person, thus starting it must begin with detoxification. It was first available in the mid-1970s as a 50 mg tablet that blocked opioids for 24-36 h if taken daily, or every 2-3 days at higher doses - for example: 100 mg Monday and Wednesday, 150 mg on Friday. From a pharmacological perspective it worked very well and was hoped to be an effective treatment but results were disappointing due to low patient interest and high dropout followed by relapse. Interest in it waned but rose again in the late 1990's when injecting opioid use and the rapid spread of HIV in the Russian Federation converged with an international interest in reducing the spread of HIV. One result was a series of meetings sponsored by the U.S. National Institute on Drug Abuse (NIDA) and Pavlov State Medical University in St. Petersburg, Russian Federation, on ways to reduce the spread of HIV in that country. Addiction treatment was a clear priority and discussions showed that naltrexone could have a role since agonist treatment is against Russian law but naltrexone is approved and the government funds over 25,000 beds for detoxification, which is the first step in starting naltrexone treatment. These meetings were followed by NIDA studies that showed better compliance to oral naltrexone than in prior U.S. studies with the expected reductions in HIV injecting risk for those that stayed in treatment. These events and findings provided a background and identified an infrastructure for the study that led to FDA approval of extended release injectable naltrexone for preventing relapse to opioid dependence. This paper will briefly review findings from these studies and end with comments on the potential role of extended release naltrexone as a meaningful addition

    Background The purpose of this study is to use mixed (qualitative/quantitative) methods to determine 1) the feasibility and acceptability of using online social networking to facilitate HIV-related discussions, and 2) the relationship between HIV-related online discussions and requests for a home-based HIV testing kit, among men who have sex with men (MSM). Methods Participants, primarily African American and Latino, were invited to join a “secret” group on the social networking website, Facebook. Peer leaders, trained in HIV prevention, posted HIV-related content. Participants were not obligated to respond to discussions or remain within the group. Participant public group conversations were qualitatively and thematically analyzed. Quantitative methods tested associations between qualitative data, participants’ demographic information, and likelihood of requesting a home-based HIV testing kit. Results Latino and African-American participants (N=57) voluntarily used Facebook to discuss the following HIV-related topics (N=485 conversations): Prevention and Testing; Knowledge; Stigma; and Advocacy. Older participants more frequently discussed Prevention and Testing, Stigma, and Advocacy, though younger participants more frequently discussed HIV Knowledge-related conversations. As the study progressed, the proportion of messages related to Prevention and Testing and HIV Stigma increased. Multivariate analysis showed that participants posting about HIV Prevention and Testing (compared to those who did not) were significantly more likely to request an HIV testing kit (OR 11.14, p = 0.001). Conclusions Facebook can serve as an innovative forum to increase both HIV prevention discussions and HIV testing requests among at-risk groups. PMID:23324979

    In face of the HIV pandemic that still grows, unsuccessful efforts of developing biomedical control measures or the failure of cognitive-behavioral approach to show sustained social level effectiveness, behavioral strategy is now expected to evolve into a structural prevention ("combination prevention") that involves multiple behavioral goals and multilevel approaches. WYSH Project is a combination prevention project for youth developed through socio-epidemiological approach that integrates epidemiology with social science such as social marketing and mixed method. WYSH Project includes mass education programs for youth in schools and programs for out-of-school youth through cyber network and peer communication. Started in 2002, it expanded nationwide with supports from related ministries and parent-teacher associations and has grown into a single largest youth prevention project in Japan. PMID:20229804

    Little is known about how combining efficacious interventions for human immunodeficiency virus (HIV) prevention could lead to HIV elimination. We used an agent-based simulation model, the HIV calibrated dynamic model, to assess the potential for HIV elimination in South Africa. We examined several scenarios (from continuation of the current status quo to perfect achievement of targets) with differing combinations of male condom use, adult male circumcision, HIV testing, and early antiretroviral therapy (ART). We varied numerous parameters, including the proportion of adult males circumcised, the frequency of condom use during sex acts, acceptance of HIV testing, linkage to health care, criteria for ART initiation, ART viral suppression rates, and loss to follow-up. Maintaining current levels of combination prevention would lead to increasing HIV incidence and prevalence in South Africa, while the perfect combination scenario was projected to eliminate HIV on a 50-year time scale from 2013 to 2063. Perfecting testing and treatment, without changing condom use or circumcision rates, resulted in an 89% reduction in HIV incidence but not elimination. Universal adult male circumcision alone resulted in a 21% incidence reduction within 20 years. Substantial decreases in HIV incidence are possible from sufficient uptake of both primary prevention and ART, but with continuation of the status quo, HIV elimination in South Africa is unlikely within a 50-year time scale.

    Although effective programmes are available and several countries have seen substantial declines in new HIV infections, progress in the reduction of adult HIV incidence has been slower than expected worldwide and many countries have not had large decreases in new infections in adults despite large reductions in paediatric infections. Reasons for slow progress include inadequate commitment, investment, focus, scale, and quality of implementation of prevention and treatment interventions. The UNAIDS-Lancet Commission on Defeating AIDS-Advancing Global Health reported that the provision of large-scale, effective HIV prevention programmes has failed and called on stakeholders to "get serious about HIV prevention". An ambitious worldwide target has been set by UNAIDS to reduce new infections below 500 000 by 2020-a 75% reduction from 2010. Models show that such a reduction requires a combination of primary prevention interventions and preventative effects of treatment. Achievement of the target will require more effective delivery of HIV prevention for sufficient coverage in populations at greatest risk of infection ensuring that interventions that have proved effective are made available, barriers to their uptake are overcome, demand is created, and use is consistent and occurs at the right scale with high coverage. This paper discusses how programmatic targets for prevention in a worldwide plan could be used to re-energise the HIV prevention approach. A management framework is proposed outlining global, regional, national, and subnational actions and is summarised in a call for action on HIV prevention for 2020. PMID:27365207

    Poverty and social inequality are significant drivers of the HIV epidemic and are risk factors for acquiring HIV. As such, many individuals worldwide are at risk for new HIV infection, especially young women in East and Southern Africa. By addressing these drivers, social protection programmes may mitigate the impact of poverty and social inequality on HIV risk. There is reason to believe that social protection can be used successfully for HIV prevention; social protection programmes, including cash transfers, have led to positive health outcomes and behaviour in other contexts, and they have been used successfully to promote education and increased income and employment opportunities. Furthermore, cash transfers have influenced sexual behaviour of young women and girls, thereby decreasing sexual risk factors for HIV infection. When HIV outcomes have been measured, several randomised controlled trials have shown that indirectly, cash transfers have led to reduced HIV prevalence and incidence. In these studies, school attendance and safer sexual health were directly incentivised through the cash transfer, yet there was a positive effect on HIV outcomes. In this review, we discuss the growth of social protection programmes, their benefits and impact on health, education and economic potential, and how these outcomes may affect HIV risk. We also review the studies that have shown that cash transfers can lead to reduced HIV infection, including study limitations and what questions still remain with regard to using cash transfers for HIV prevention.

    Background We explored rural African American youths' perceptions about the role of community social institutions in addressing HIV. Methods We conducted four focus groups with African Americans aged 16 to 24 years in two rural counties in North Carolina. Groups were stratified by gender and risk status. We used a grounded theory approach to content analysis. Results Participants identified four social institutions as primary providers of HIV-related health promotion efforts: faith organizations, schools, politicians, and health agencies. They reported perceiving a lack of involvement in HIV prevention by faith-based organizations, constraints of abstinence-based sex education policies, politicians' lack of interest in addressing broader HIV determinants, and inadequacies in health agency services, and viewed all of these as being counter-productive to HIV prevention efforts. Conclusions youth have important insights about local social institutions that should be considered when designing HIV prevention interventions that partner with local organizations. PMID:20453373

    Objective Enhanced HIV prevention interventions, such as pre-exposure prophylaxis for high-risk individuals, require substantial investments. We sought to estimate the medical cost saved by averting one HIV infection in the United States. Methods We estimated lifetime medical costs in persons with and without HIV to determine the cost saved by preventing one HIV infection. We used a computer simulation model of HIV disease and treatment (CEPAC) to project CD4 cell count, antiretroviral treatment status, and mortality after HIV infection. Annual medical cost estimates for HIV-infected persons, adjusted for age, sex, race/ethnicity, and transmission risk group, were from the HIV Research Network (range $1,854–$4,545/month) and for HIV-uninfected persons were from the Medical Expenditure Panel Survey (range $73–$628/month). Results are reported as lifetime medical costs from the US health system perspective discounted at 3% (2012 US dollars). Results The estimated discounted lifetime cost for persons who become HIV infected at age 35 is $326,500 (60% for antiretroviral medications, 15% for other medications, 25% non-drug costs). For individuals who remain uninfected but at high risk for infection, the discounted lifetime cost estimate is $96,700. The medical cost saved by avoiding one HIV infection is $229,800. The cost saved would reach $338,400 if all HIV-infected individuals presented early and remained in care. Cost savings are higher taking into account secondary infections avoided and lower if HIV infections are temporarily delayed rather than permanently avoided. Conclusions The economic value of HIV prevention in the US is substantial given the high cost of HIV disease treatment. PMID:25710311

    Relatively few studies have examined the impact of modifying structural factors on HIV prevention efforts in the United States despite their high potential for lowering HIV prevalence rates. The aim of this study was to identify state-level characteristics of successful HIV prevention implementation. Structured interviews with 73 key informants in 13 rural states identified ‘more successful’ and ‘less successful’ states in HIV prevention. States were compared on demographic, religious, gay community, and funding variables. The 7 more successful states had both a wider variety and more MSM-targeted interventions. Overall funding, degree of epidemic, and “ruralness” were not significantly associated with success. Rather, successful states had less religious and Evangelical Protestant adherents and more ‘gay community’ infrastructure. They also spent a greater proportion of funds contracting community-based organizations and on MSMtargeted programming. Success in HIV prevention varies across rural states. Key demographic, social and economic indicators distinguish success in HIV prevention. PMID:17440806

    Introduction There are limited data characterizing the burden of HIV among men who have sex with men (MSM) in Malawi. Epidemiologic research and access to HIV prevention, treatment and care services have been traditionally limited in Malawi by criminalization and stigmatization of same-sex practices. To inform the development of a comprehensive HIV prevention intervention for Malawian MSM, we conducted a community-led assessment of HIV prevalence and correlates of infection. Methods From April 2011 to March 2012, 338 MSM were enrolled in a cross-sectional study in Blantyre, Malawi. Participants were recruited by respondent-driven sampling methods (RDS), reaching 19 waves. Trained staff administered the socio-behavioural survey and HIV and syphilis voluntary counselling and testing. Results Crude HIV and syphilis prevalence estimates were 15.4% (RDS-weighted 12.5%, 95% confidence interval (CI): 7.3–17.8) and 5.3% (RDS-weighted 4.4%, 95% CI: 3.1–7.6), respectively. Ninety per cent (90.4%, unweighted) of HIV infections were reported as being previously undiagnosed. Participants were predominantly gay-identified (60.8%) or bisexually identified (36.3%); 50.7% reported recent concurrent relationships. Approximately half reported consistent condom use (always or almost always) with casual male partners, and proportions were relatively uniform across partner types and genders. The prevalence of perceived and experienced stigma exceeded 20% for almost all variables, 11.4% ever experienced physical violence and 7% were ever raped. Current age >25 years (RDS-weighted adjusted odds ratio (AOR) 3.9, 95% CI: 1.2–12.7), single marital status (RDS-weighted AOR: 0.3; 95% CI: 0.1–0.8) and age of first sex with a man <16 years (RDS-weighted AOR: 4.3, 95% CI: 1.2–15.0) were independently associated with HIV infection. Conclusions Results demonstrate that MSM represent an underserved, at-risk population for HIV services in Malawi and merit comprehensive HIV prevention

    The impact of a professionally facilitated peer group intervention for HIV prevention among 400 low-income Chilean women was examined using a quasiexperimental design. At 3 months postintervention, the intervention group had higher HIV-related knowledge, more positive attitudes toward people living with HIV, fewer perceived condom use barriers, greater self- efficacy, higher HIV reduction behavioral intentions, more communication with partners about safer sex, and decreased depression symptoms. They did not, however, have increased condom use or self-esteem. More attention to gender barriers is needed. This intervention offers a model for reducing HIV for women in Chile and other Latin American countries. PMID:22420675

    HIV-related stigma, discrimination, and homophobia impede community based efforts to combat HIV disease among Latino and African American gay and bisexual men. This commentary highlights ways to address these social biases in communities of color in Los Angeles from the perspectives of staff from HIV prevention programs. Information was collected from HIV prevention program staff participating in a two-day symposium. The outcomes from the symposium offer strategies for developing and implementing HIV prevention services for Latino and African American gay and bisexual men, which include: 1) addressing social biases present in a community that can hinder, and even prohibit, utilization of effective HIV prevention programs; 2) recasting HIV prevention messages in a broader social or health context; 3) developing culturally appropriate HIV prevention messages; 4) exploring new modalities and venues for delivering HIV prevention messages that are appropriate for gay and bisexual men of color and the communities in which they live; and 5) broadening the target of HIV prevention services to include service providers, local institutions and agencies, and the community at-large. These strategies underscore the need to consider the social and contextual factors of a community when designing and implementing HIV prevention programs. PMID:16283834

    Gay bathhouses (including sex clubs) contributed to HIV prevention from the early days of the AIDS epidemic, but the extent to which prevention interventions are implemented in bathhouses is unknown. Using telephone survey methodology, bathhouse managers provided data about HIV prevention in their bathhouses. All the bathhouses provided free condoms, and nearly all displayed educational posters in public areas and had informational pamphlets available for patrons. A few of the bathhouses offered outreach services and counseling services. Almost all promoted testing for HIV/sexually transmitted infection (which included providing information about where to get tested), and 75.5% had HIV testing programs in their venues. Most of the HIV testing programs were started during the past 5 years, initiated by the bathhouse management or a community agency, and operated by community-based agencies. About one third of the programs offered rapid HIV testing. The results of the telephone survey revealed that all the bathhouses engaged in prevention and many offered a wide range of prevention services, suggesting that managers have embraced the issue of HIV and collaborated in bringing prevention to high-risk men. The absence of studies evaluating these prevention efforts remains a concern and an obstacle for efficient use of the prevention resources. PMID:21406994

    Clinical trial data have shown that oral pre-exposure prophylaxis (PrEP) is efficacious when taken as prescribed; however, PrEP adherence is complex and must be understood within the context of variable risk for HIV infection and use of other HIV prevention methods. Different levels of adherence may be needed in different populations to achieve HIV prevention, and the optimal methods for achieving the necessary adherence for both individual and public health benefits are unknown. Guidance for PrEP use must consider these questions to determine the success of PrEP-based HIV prevention programs. In this article, we propose a new paradigm for understanding and measuring PrEP adherence, termed prevention-effective adherence, which incorporates dynamic HIV acquisition risk behaviors and the use of HIV alternative prevention strategies. We discuss the need for daily PrEP use only during periods of risk for HIV exposure, describe key issues for measuring and understanding relevant behaviors, review lessons from another health prevention field (i.e., family planning), and provide guidance for prevention-effective PrEP use. Moreover, we challenge emerging calls for sustained, near perfect PrEP adherence regardless of risk exposure and offer a more practical and public health-focused vision for this prevention intervention.

    Using multiple network comparisons, we determined whether sexually transmitted disease (STD) rates or black-white STD rate differences are related to how HIV prevention agencies interact through exchanges of information, clients, or funds. In 10 North Carolinian counties, we conducted a cross-sectional analysis, using each county's network as the unit of interest. Using data from face-to-face interviews, measures of the density (overall connectedness) and degree centralization (amount of centralized information hubs) were calculated with UCINET. Statistical significance of the associations between county characteristics and STD rates was assessed with exact Wilcoxon rank sum test. Syphilis rates were lower (P = .01) in counties with a high network density, on the basis of exchanges of information or clients. The effect on black-white rate differences was in the same direction but weaker. Where network degree centralization was high, syphilis rates were higher and the black-white rate differences were larger. Gonorrhea rates demonstrated similar but attenuated patterns of association with network characteristics. STD prevention is more effective when all agencies interact with each other (density) but less effective when interactions are predominantly with a few central agencies (degree centralization). The measures of network exchanges employed in this study may be appropriate for future assessment of service provision of funded prevention programs. PMID:18091030

    Over the past decade, a wealth of experimental evidence has accumulated supporting the importance of Fc receptor (FcR) ligation in antibody-mediated pathology and protection in many disease states. Here we present the diverse evidence base that has accumulated as to the importance of antibody effector functions in the setting of HIV prevention and therapy, including clinical correlates, genetic associations, viral evasion strategies, and a rapidly growing number of compelling animal model experiments. Collectively, this work identifies antibody interactions with FcR as important to both therapeutic and prophylactic strategies involving both passive and active immunity. These findings mirror those in other fields as investigators continue to work toward identifying the right antibodies and the right effectors to be present at the right sites at the right time.

    For more than 20 years cationic surfactant Miramistin has been used in Russia and Ukraine as an antiseptic mean for individual prophylaxis of venereal diseases and for the treatment of genitourinary tract and other systems infections. Complete inhibition of HIV-1 activity in vitro by Miramistin in concentrations higher than 0.0075%, has been demonstrated, that allows to consider this detergent as a potent first-generation vaginal microbicide for the prevention of HIV transmission. Higher anti-HIV effect of Miramistin than of nonoxynol-9 and low local toxicity show good prospects of using Miramistin for individual prevention of HIV transmission. PMID:24605621

    Acquired immune deficiency syndrome has been one of the most devastating epidemics of the last century. The current estimate for people living with the HIV is 36.9 million. Today, despite availability of potent and safe drugs for effective treatment, lifelong therapy is required for preventing HIV re-emergence from a pool of latently infected cells. However, recent evidence show the importance to expand HIV testing, to offer antiretroviral treatment to all infected individuals, and to ensure retention through all the cascade of care. In addition, circumcision, pre-exposure prophylaxis, and other biomedical tools are now available for included in a comprehensive preventive package. Use of all the available tools might allow cutting the HIV transmission in 2030. In this article, we review the status of the epidemic, the latest advances in prevention and treatment, the concept of treatment as prevention and the challenges and opportunities for the HIV cure agenda.

    HIV-prevention intervention effectiveness depends on understanding whether clients with highest need for HIV-prevention counseling accept it. With this objective, a field study with a high-risk community sample from the southeastern United States (N = 350) investigated whether initial knowledge about HIV, motivation to use condoms, condom-use-relevant behavioral skills, and prior condom use correlate with subsequent acceptance of an HIV-prevention counseling session. Ironically, participants with high (vs. low) motivation to use condoms, high (vs. low) condom-use-relevant behavioral skills, and high (vs. low) prior condom use were more likely to accept the HIV-prevention counseling. Moreover, the influence of motivation to use condoms, condom-use-relevant behavioral skills, and prior condom use on acceptance of the counseling was mediated by expectations that the counseling session would be useful. Methods to reduce barriers to recruitment of clients for counseling programs are discussed. PMID:19634960

    Despite efforts to increase access to HIV testing and counseling services, population coverage remains low. As a result, many people in sub-Saharan Africa do not know their own HIV status or the status of their sex partner(s). Recent evidence, however, indicates that as many as half of HIV-positive individuals in ongoing sexual relationships have an HIV-negative partner and that a significant proportion of new HIV infections in generalized epidemics occur within serodiscordant couples. Integrating couples HIV testing and counseling (CHTC) into routine clinic- and community-based services can significantly increase the number of couples where the status of both partners is known. Offering couples a set of evidence-based interventions once their HIV status has been determined can significantly reduce HIV incidence within couples and if implemented with sufficient scale and coverage, potentially reduce population-level HIV incidence as well. This article describes these interventions and their potential benefits. PMID:23656251

    Identifying venues where women meet sexual partners, particular partners who increase women's risk of acquiring HIV, could inform prevention efforts. We categorized venues where women enrolled in HPTN 064 reported meeting their last three sex partners as: (1) Formal, (2) Public, (3) Private, and (4) Virtual spaces. We used multinomial logistic regression to assess the association between these venues and women's individual characteristics and reports of their partners' HIV risk characteristics. The 2099 women reported meeting 3991 partners, 51 % at Public, 30 % Private, 17 % Formal and 3 % at Virtual venues. Women meeting partners at Formal venues reported more education and condom use than women meeting partners at other venues. Fewer partners met through Formal venues had "high" risk characteristics for HIV than through other venues and hence may pose less risk of HIV transmission. HIV prevention interventions can help women choose partners with fewer risk characteristics across all venue types. PMID:25863466

    Daily oral tenofovir (TDF)-based pre-exposure prophylaxis (PrEP) is an effective HIV prevention strategy and recommended for men and women with substantial risk of HIV acquisition. The peri-conception period, the stage prior to pregnancy when condom use is necessarily reduced, has elevated HIV risk that can be mitigated by PrEP use. Data from a randomized trial suggest that peri-conception PrEP use by HIV-seronegative women does not increase the risk of pregnancy loss, birth defects or congenital anomalies, preterm birth, or infant growth faltering. Women considering PrEP use throughout pregnancy must weigh the known increased risk of HIV acquisition with unknown risks of drug effects on infant growth. PrEP has been used safely by HIV-seronegative men with HIV-seropositive female partners who have become pregnant. As an effective user-controlled HIV prevention strategy, PrEP offers autonomy and empowerment for HIV prevention and can be recommended alongside antiretroviral therapy, fertility screening, vaginal self-insemination, intercourse timed to peak fertility, medically assisted reproduction, and other safer conception strategies to provide multiple options. The integration of PrEP into safer conception programs is warranted and will safely reduce HIV transmission to women, men, and children during the peri-conception period. PMID:26993627

    For a country with a moderate adult HIV prevalence of just over 1% in 2012, Thailand is widely perceived as having made some extraordinary contributions to the global management of the HIV/AIDS pandemic. It has been promoted as a model of effective HIV control and applauded for its leadership in providing access to antiretroviral treatment. Thailand has also received international recognition for its contribution to biomedical HIV prevention research, which is generally perceived as exceptional. In this paper, Thailand's global role model function as an example of effective HIV/AIDS control and high-quality biomedical HIV prevention research is re-evaluated against the background of currently available data and more recent insights. The results indicate that Thailand's initial response in raising the level of the political significance of HIV/AIDS was indeed extraordinary, which probably prevented a much larger epidemic from occurring. However, this response transpired in unusual extraconstitutional circumstances and its effectiveness declined once the country returned to political normalcy. Available data confirm the country's more than exceptional contribution to biomedical HIV prevention research. Thailand has made a huge contribution to the global management and control of the HIV/AIDS pandemic. PMID:25000363

    Using popular culture to engage students in discussions of HIV prevention is a nontraditional approach that may complement current prevention efforts and enhance the ability to reach youth who are at high risk of contracting HIV and other sexually transmitted infections. Hip-hop or rap music is the dominant genre of music among adolescents, especially Black and Latino youth who are disproportionately impacted by HIV and AIDS. This paper describes the rationale and development of the Reducing HIV and AIDS through Prevention (RHAP) program, a school-based program that uses hip-hop/rap music as a vehicle for raising awareness among adolescents about HIV/AIDS. Constructs from the Social Cognitive Theory and the Sexual Script Theory were used in developing the program. It was piloted and evaluated among 26 middle school students in East Harlem, New York. The lessons learned from a formative evaluation of the program and the implications for developing other programs targeting public health problems are discussed. The RHAP program challenges the traditional pedagogue–student paradigm and provides an alternative approach to teaching about HIV prevention and awareness. PMID:20195778

    A quarter of a century of AIDS responses has created a huge body of knowledge about HIV transmission and how to prevent it, yet every day, around the world, nearly 7000 people become infected with the virus. Although HIV prevention is complex, it ought not to be mystifying. Local and national achievements in curbing the epidemic have been myriad, and have created a body of evidence about what works, but these successful approaches have not yet been fully applied. Essential programmes and services have not had sufficient coverage; they have often lacked the funding to be applied with sufficient quality and intensity. Action and funding have not necessarily been directed to where the epidemic is or to what drives it. Few programmes address vulnerability to HIV and structural determinants of the epidemic. A prevention constituency has not been adequately mobilised to stimulate the demand for HIV prevention. Confident and unified leadership has not emerged to assert what is needed in HIV prevention and how to overcome the political, sociocultural, and logistic barriers in getting there. We discuss the combination of solutions which are needed to intensify HIV prevention, using the existing body of evidence and the lessons from our successes and failures in HIV prevention.

    Early initiation of antiretroviral treatment (ART) reduces HIV transmission and has health benefits. HIV drug resistance can limit treatment options and compromise use of ART for HIV prevention. We evaluated drug resistance in 85 participants in the HIV Prevention Trials Network 052 trial who started ART at CD4 counts of 350-550 cells per cubic millimeter and failed ART by May 2011; 8.2% had baseline resistance and 35.3% had resistance at ART failure. High baseline viral load and less education were associated with emergence of resistance at ART failure. Resistance at ART failure was observed in 7 of 8 (87.5%) participants who started ART at lower CD4 cell counts. PMID:26859828

    AIM This study investigated how parents living with HIV communicated about HIV prevention with their 10–18 year old children. METHODS Interviews with 76 mothers and fathers were analyzed for (1) their experiences discussing HIV prevention with adolescents, and (2) advice on how to best broach HIV-related topics. RESULTS Interactive conversations, where both parents and adolescents participated, were regarded as effective. Parents emphasized that adolescents should have a “voice” (be able to voice their concerns) and a “choice” (have a variety of effective prevention strategies to choose from) during HIV-related talks. DISCUSSION A five step process for interactive communication emerged as a result of these discussions. IMPLICATIONS Health care professionals can facilitate adolescent sexual health by encouraging parents to actively involve their children in discussions about HIV prevention. CONCLUSION Future HIV prevention programs could benefit by providing parents with appropriate tools to foster interactive discussions about sexual health with adolescents. PMID:24683366

    The advent of pre-exposure prophylaxis (PrEP) and treatment as prevention (TasP) as means of HIV prevention raises issues of justice concerning how most fairly and equitably to apportion resources in support of the burgeoning variety of established HIV treatment and prevention measures and further HIV research, including HIV vaccine research. We apply contemporary approaches to social justice to assess the ethical justification for allocating resources in support of HIV vaccine research given competing priorities to support broad implementation of HIV treatment and prevention measures, including TasP and PrEP. We argue that there is prima facie reason to believe that a safe and effective preventive HIV vaccine would offer a distinct set of ethically significant benefits not provided by current HIV treatment or prevention methods. It is thereby possible to justify continued support for HIV vaccine research despite tension with priorities for treatment, prevention, and other research. We then consider a counter-argument to such a justification based on the uncertainty of successfully developing a safe and effective preventive HIV vaccine. Finally, we discuss how HIV vaccine research might now be ethically designed and conducted given the new preventive options of TasP and PrEP, focusing on the ethically appropriate standard of prevention for HIV vaccine trials.

    Men who have sex with men (MSM) represent 64.0% of people living with HIV (PLWH) over the age of 13 years. Young men who have sex with men (YMSM) are particularly affected by HIV/AIDS; the rate of HIV infection for YMSM between the ages of 13 and 24 represents 72.0% of new infections among youth. To understand the current state of the science meant to prevent HIV for YMSM, we reviewed studies of HIV behavioral prevention interventions for YMSM. Five literature databases were searched, from their inception through October 2015, using key words associated with HIV prevention intervention evaluation studies for YMSM. The review criteria included behavioral HIV/AIDS prevention interventions, articles published in English-language peer-reviewed journals, YMSM between 13 and 24 years of age, and longitudinal repeated measures design. A total of 15 YMSM behavioral HIV prevention intervention studies were identified that met inclusion criteria and reported statistically significant findings. Common outcomes included unprotected sexual intercourse, HIV/AIDS risk behavior, condom use, HIV testing, safer sex attitude, and HIV prevention communication. Participant age, representation of Black/African American YMSM, application of theoretical and model underpinnings, congruence of assessment measures used, follow-up assessment times, and application of process evaluation were inconsistent across studies. To advance HIV prevention intervention research for YMSM, future studies should be theory-based, identify common constructs, utilize standard measures, include process evaluation, and evaluate sustained change over standard periods of time. HIV prevention interventions should incorporate the needs of the diverse, well-educated, web-connected millennial generation and differentiate between adolescent YMSM (13 to 18 years of age) and young adulthood YMSM (19 to 24 years of age). Because Black/African American YMSM represent more than 50% of new HIV infections, future HIV

    Men who have sex with men (MSM) have been substantially affected by HIV epidemics worldwide. Epidemics in MSM are re-emerging in many high-income countries and gaining greater recognition in many low-income and middle-income countries. Better HIV prevention strategies are urgently needed. Our review of HIV prevention strategies for MSM identified several important themes. At the beginning of the epidemic, stand-alone behavioural interventions mostly aimed to reduce unprotected anal intercourse, which, although somewhat efficacious, did not reduce HIV transmission. Biomedical prevention strategies reduce the incidence of HIV infection. Delivery of barrier and biomedical interventions with coordinated behavioural and structural strategies could optimise the effectiveness of prevention. Modelling suggests that, with sufficient coverage, available interventions are sufficient to avert at least a quarter of new HIV infections in MSM in diverse countries. Scale-up of HIV prevention programmes for MSM is difficult because of homophobia and bias, suboptimum access to HIV testing and care, and financial constraints. PMID:22819659

    Purpose of review Despite tremendous promise as a female-controlled HIV prevention strategy, implementation of pre-exposure prophylaxis (PrEP) among women has been limited, in part because of disparate efficacy results from randomized trials in this population. This review synthesizes existing evidence regarding PrEP efficacy for preventing HIV infection in women and considerations for delivering PrEP to women. Recent findings In three efficacy trials, conducted among men and women, tenofovir-based oral PrEP reduced HIV acquisition in subgroups of women by 49–79% in intent-to-treat analyses, and by >85% when accounting for PrEP adherence. Two trials did not demonstrate an HIV prevention benefit from PrEP in women, but substantial evidence indicates those results were compromised by very low adherence to the study medication. Qualitative research has identified risk perception, stigma, and aspects of clinical trial participation as influencing adherence to study medication. Pharmacokinetic studies provide supporting evidence that PrEP offers HIV protection in women who are adherent to the medication. Summary Tenofovir-based daily oral PrEP prevents HIV acquisition in women. Offering PrEP as an HIV prevention option for women at high risk of HIV acquisition is a public health imperative and opportunities to evaluate implementation strategies for PrEP for women are needed.

    2010-01-01

    Comprehensive HIV prevention interventions are increasingly recognized as critical in the global effort to reduce HIV transmission among people who use injection drugs (IDU). Scientific evidence clearly shows that a variety of biomedical, behavioral and structural interventions can prevent and reduce IDU-driven HIV epidemics, yet social and structural barriers to their implementation remain. This review discusses the scientific evidence on the effectiveness of individual programs for reducing HIV incidence among IDU and how, by integrating individual programs as complements within a comprehensive HIV prevention approach, it is possible to achieve, and to sustain, greater results than those of individual programs alone. The paper concludes with a discussion of a critical research priority; namely, to improve the implementation of comprehensive HIV prevention interventions in settings of prevalent injection drug use, and to overcome the often complex barriers that impede them. Such an effort will require more than research alone, however. It will also require the ongoing commitment of policy makers, public health officials, and the affected communities themselves to employ comprehensive HIV treatment and prevention as the most effective strategy to reduce new HIV infections.

    The HIV epidemic continues to disproportionately affect ethnic minority youth. These disconcerting health disparities indicate that although existing HIV preventive strategies for ethnic minority youth have been efficacious, they have not significantly reduced the impact of the epidemic in this population. Macro-level interventions, such as structural or policy interventions, have the potential to impact the HIV epidemic at a population level, and thus reduce the HIV health disparities that exist among ethnic minority youth and other segments of the U.S. population. This article calls for a paradigm shift to develop, evaluate, and disseminate interventions that target upstream/macro-level factors or that, at a minimum, integrate both a macro and individual level perspective. The article also discusses the challenges in developing and evaluating such interventions. Psychologists and other behavioral scientists can play a critical role in reducing the impact of HIV on ethnic minority youth by integrating macro-level approaches to future HIV prevention strategies.

    Greater understanding of barriers to risk reduction among incarcerated HIV+ persons reentering the community is needed to inform culturally tailored interventions. This qualitative study elicited HIV prevention-related information, motivation and behavioral skills (IMB) needs of 30 incarcerated HIV+ men and women awaiting release from state prison. Unmet information needs included risk questions about viral loads, positive sexual partners, and transmission through casual contact. Social motivational barriers to risk reduction included partner perceptions that prison release increases sexual desirability, partners’ negative condom attitudes, and HIV disclosure-related fears of rejection. Personal motivational barriers included depression and strong desires for sex or substance use upon release. Behavioral skills needs included initiating safer behaviors with partners with whom condoms had not been used prior to incarceration, disclosing HIV status, and acquiring clean needles or condoms upon release. Stigma and privacy concerns were prominent prison context barriers to delivering HIV prevention services during incarceration. PMID:21553252

    With the continuing march of the AIDS epidemic and little hope for an effective vaccine in the near future, work to develop a topical strategy to prevent HIV infection is increasingly important. This stated, the track record of large scale "microbicide" trials has been disappointing with nonspecific inhibitors either failing to protect women from infection or even increasing HIV acquisition. Newer strategies that target directly the elements needed for viral entry into cells have shown promise in non-human primate models of HIV transmission and as these agents have not yet been broadly introduced in regions of highest HIV prevalence, they are particularly attractive for prophylaxis. We review here the agents that can block HIV cellular entry and that show promise as topical strategies or "virustats" to prevent mucosal transmission of HIV infection PMID:19094217

    Until now, decisions about how to allocate ART have largely been based on maximising the therapeutic benefit of ART for patients. Since the results of the HPTN 052 study showed efficacy of antiretroviral therapy (ART) in preventing HIV transmission, there has been increased interest in the benefits of ART not only as treatment, but also in prevention. Resources for expanding ART in the short term may be limited, so the question is how to generate the most prevention benefit from realistic potential increases in the availability of ART. Although not a formal systematic review, here we review different ways in which access to ART could be expanded by prioritising access to particular groups based on clinical or behavioural factors. For each group we consider (i) the clinical and epidemiological benefits, (ii) the potential feasibility, acceptability, and equity, and (iii) the affordability and cost-effectiveness of prioritising ART access for that group. In re-evaluating the allocation of ART in light of the new data about ART preventing transmission, the goal should be to create policies that maximise epidemiological and clinical benefit while still being feasible, affordable, acceptable, and equitable.

    Objective(s) Few HIV prevention interventions have been evaluated in randomized controlled trials (RCTs). We examined design, implementation, and contextual considerations that may limit detection of a positive or adverse effect in HIV prevention trials. Design A systematic review of late phase RCTs for prevention of sexual transmission of HIV that 1) randomly allocated intervention and comparison groups; 2) evaluated interventions to prevent sexual transmission in non-pregnant populations; and 3) reported HIV incidence as the primary or secondary outcome. Methods PubMed/MEDLINE, other electronic databases, and electronic conference proceedings of recent HIV/AIDS-related conferences were searched to identify published or unpublished trials meeting the inclusion criteria. Descriptive, methodological, and contextual factors were abstracted from each trial. Results The review included 36 HIV prevention RCTs reporting on 38 unique interventions. Only six RCTs, all evaluating biomedical interventions, demonstrated definitive effects on HIV incidence. Five of the six RCTs significantly reduced HIV infection: all three male circumcision trials, one trial of STI treatment and care, and one vaccine trial. One microbicide trial of nonoxynol-9 gel produced adverse results. Lack of statistical power, poor adherence, and diluted versions of the intervention in comparison groups may have been important issues for the other trials that demonstrated “flat” results. Conclusions Almost 90% of HIV prevention trials had “flat” results, which may be attributable to trial design and/or implementation. The HIV prevention community must not only examine evidence from significant RCTs, but must also examine flat trials, and address design and implementation issues that limit detection of an effect.

    It is a hard work to develop an hightly effective cure and prevention of HIV/AIDS. The widespread used of some therapy approaches such as highly active anti retroviral therapy (HAART) has improved life quality and span of infected individuals. However, some limitations of these approaches prevent them achieving further advancement. Recent research on drug delivery approaches indicates that engineered nanosystems may bring positive effect on the improvement of current antiretroviral therapy. Furthermore, the basic researches of nanotechnology- based systems which prevent HIV transmission have been started. Therefore, nanotechnology may become a potential approach in the field of HIV/AIDS treatment and prevention. This chapter reviews the latest advancement in the field of nanotechnology-based systems which improve the fields of HIV/AIDS treatment and prevention.

    The black church is influential in shaping health behaviors within African-American communities, yet few use evidence-based strategies for HIV prevention (abstinence, monogamy, condoms, voluntary counseling and testing, and prevention with positives). Using principles of grounded theory and interpretive description, we explored the social construction of HIV prevention within black Baptist churches in North Carolina. Data collection included interviews with church leaders (n = 12) and focus groups with congregants (n = 7; 36 participants). Analytic tools included open coding and case-level comparisons. Social constructions of HIV/AIDS prevention were influenced by two worldviews: public health and church-based. Areas of compatibility and incompatibility exist between the two worldviews that inform acceptability and adaptability of current evidence-based strategies. These findings offer insight into ways to increase the compatibility of evidence-based HIV prevention strategies within the black Baptist church context. PMID:24643141

    Structural interventions have been defined as those prevention interventions that include physical, social, cultural, organizational, community, economic, legal, and policy factors. In an effort to examine the feasibility, evaluability, and sustainability of structural interventions for HIV prevention, the Centers for Disease Control and Prevention implemented a project that involved asking experts in HIV prevention and other areas of public health-including injury and violence prevention, tobacco control, drug abuse, and nutrition-to provide input on the identification of structural interventions based on the aforementioned definition. The process resulted in a list of 123 interventions that met the definition. The experts were asked to group these interventions into categories based on similarity of ideas. They were also asked to rate these interventions in terms of impact they would have, if implemented, on reducing HIV transmission. The findings highlight the need for conducting further research on structural interventions, including feasibility of implementation and effectiveness of reducing HIV transmission risks.

    The HIV epidemic among men who have sex with men (MSM) has been increasing at an alarming rate in most areas of China in recent years. Many Chinese MSM still lack sufficient access to HIV prevention services, despite ongoing scale-up of comprehensive HIV testing and intervention services. The purpose of this study was to investigate utilization of HIV testing and prevention services, and related factors that influence the MSM people to access HIV test or other services to prevent HIV among MSM in Beijing, China.Three successive cross-sectional surveys of MSM were conducted in Beijing from September 2009 to January 2010, September 2010 to January 2011, and September 2011 to January 2012. Demographic and behavioral data were collected and analyzed. Blood samples were tested for HIV and syphilis. Three models were established to analyze factors associated with HIV testing and preventive services.Of the 1312 participants, prevalence of HIV and syphilis was 7.9% and 15.4%, respectively. Sixty-nine percent ever had an HIV test, 56.2%, 78.7%, and 46.1% received HIV test, free condom/lubricants, and sexually transmitted infection services in the past 12 months (P12M), respectively. MSM with larger social networks and who knew someone infected with HIV were more likely to receive HIV testing and preventive services; lower degrees of stigma and discriminatory attitudes toward HIV/AIDS were positively associated with having an HIV test, whereas unprotected anal intercourse in the past 6 months (P6M) was associated with less preventive services participation. The most reported barriers to HIV testing were fear of testing HIV positive (79.3%) and perceiving no risk for HIV (75.4%). Almost all participants felt that ensuring confidentiality would encourage more MSM to have an HIV test. The two main reasons for not seeking HIV test was not knowing where to go for a test (63.2%) and perceiving low risk of HIV infection (55.1%).Given a high prevalence of HIV, syphilis, and risky

MSM with larger social networks and who knew someone infected with HIV were more likely to receive HIV testing and preventive services; lower degrees of stigma and discriminatory attitudes toward HIV/AIDS were positively associated with having an HIV test, whereas unprotected anal intercourse in the past 6 months (P6M) was associated with less preventive services participation. The most reported barriers to HIV testing were fear of testing HIV positive (79.3%) and perceiving no risk for HIV (75.4%). Almost all participants felt that ensuring confidentiality would encourage more MSM to have an HIV test. The two main reasons for not seeking HIV test was not knowing where to go for a test (63.2%) and perceiving low risk of HIV infection (55.1%). Given a high prevalence of HIV, syphilis

    Multipurpose prevention technologies (MPTs) designed to simultaneously prevent pregnancy and HIV could provide urgently needed tools to address unmet sexual and reproductive health needs of women worldwide. Late-stage clinical trials will be complex given the need to demonstrate efficacy for HIV and contraceptive indications simultaneously from a single product. Currently, HIV and pregnancy prevention trials have distinctive design features that will need to be reconciled in MPT trials. This article identifies several ethical issues uniquely associated with this research that will benefit from future deliberation and guidance to ensure that this globally important research can proceed efficiently and expeditiously.

    Abstract: Worldwide, transgender women are at disproportionately higher risk of HIV infection, with the primary mode of infection being condomless anal intercourse. Although very few HIV prevention interventions have been developed and tested specifically for transgender women, growing evidence suggests that behavioral HIV risk reduction interventions for other marginalized groups are efficacious. We outline the current state of knowledge and areas in need of further development in this area. PMID:27429186

  4. HIV Treatment as Prevention: Models, Data, and Questions—Towards Evidence-Based Decision-Making

    PubMed Central

    2012-01-01

    Antiretroviral therapy (ART) for those infected with HIV can prevent onward transmission of infection, but biological efficacy alone is not enough to guide policy decisions about the role of ART in reducing HIV incidence. Epidemiology, economics, demography, statistics, biology, and mathematical modelling will be central in framing key decisions in the optimal use of ART. PLoS Medicine, with the HIV Modelling Consortium, has commissioned a set of articles that examine different aspects of HIV treatment as prevention with a forward-looking research agenda. Interlocking themes across these articles are discussed in this introduction. We hope that this article, and others in the collection, will provide a foundation upon which greater collaborations between disciplines will be formed, and will afford deeper insights into the key factors involved, to help strengthen the support for evidence-based decision-making in HIV prevention.

  5. A typology of structural approaches to HIV prevention: a commentary on Roberts and Matthews.

    PubMed

    Tsai, Alexander C

    2012-11-01

    Renewed enthusiasm for biomedical HIV prevention strategies has followed the recent publication of several high-profile HIV antiretroviral therapy-based HIV prevention trials. In a recent article, Roberts and Matthews (2012) accurately note some of the shortcomings of these individually targeted approaches to HIV prevention and advocate for increased emphasis on structural interventions that have more fundamental effects on the population distribution of HIV. However, they make some implicit assumptions about the extent to which structural interventions are user-independent and more sustainable than biomedical or behavioral interventions. In this article, I elaborate a simple typology of structural interventions along these two axes and suggest that they may be neither user-independent nor sustainable and therefore subject to the same sustainability concerns, costs, and potential unintended consequences as biomedical and behavioral interventions.

    2010-01-01

    We present a model for HIV-related behaviors that emphasizes the dynamic and social nature of the structural factors that influence HIV prevention and detection. Key structural dimensions of the model include resources, science and technology, formal social control, informal social influences and control, social interconnectedness, and settings. These six dimensions can be conceptualized on macro, meso, and micro levels. Given the inherent complexity of structural factors and their interrelatedness, HIV prevention interventions may focus on different levels and dimensions. We employ a systems perspective to describe the interconnected and dynamic processes of change among social systems and their components. The topics of HIV testing and safer injection facilities are analyzed using this structural framework. Finally, we discuss methodological issues in the development and evaluation of structural interventions for HIV prevention and detection. PMID:20838871

    The aim of the cross-sectional study was to understand gender differences in HIV/AIDS preventive self-efficacy among Taiwanese adolescents. Self-administered questionnaires were used to measure HIV/AIDS preventive self-efficacy and covariates (age, substance use, and sexual experiences). Data were collected from 734 Taiwanese high school adolescents aged 16 to 18 years. Descriptive statistic analyses, t-test, and ANCOVA were utilized to analyze data. The results indicate significant differences exist between genders in HIV/AIDS preventive self-efficacy among Taiwanese adolescents. Compared to the males, female adolescents were found having significantly higher HIV/AIDS preventive self-efficacy related to refusing sexual intercourse, condom use, and questioning potential sexual partners than those who are males. While controlling age, sexual experience, and substance use, female Taiwanese adolescents also had higher HIV/AIDS preventive self-efficacy than those who are males. The findings suggest the importance of addressing gender differences in HIV/AIDS preventive self-efficacy when developing HIV reduction programs for Taiwanese adolescents. PMID:26829258

    The objective of this paper is to review the current status of drug use and HIV/AIDS prevention for drug users in China and provide scientific evidence for HIV/AIDS prevention and control in drug users. Literature and articles related to drug abuse in China, as well as the results of prevention efforts and successful cases regarding HIV/AIDS prevention in drug users, are reviewed. Lessons learned are drawn out for the future improvement of work and the sustainable development of treatment programs. The number of drug users in China is increasing. Even though the number of opioid-type drug users is growing more slowly than in the past, the number of amphetamine-type stimulant users has increased sharply. It has been proven that methadone maintenance treatment and syringe exchange programs gradually and successfully control HIV/AIDS transmission in drug users. However, it is necessary to enhance these prevention methods and expand their coverage. In addition, the strengthening of antiretroviral therapy (ART) treatment for HIV-infected drug users is crucial for HIV/AIDS prevention and control. The rapidly growing number of amphetamine-type stimulant users, along with their high-risk behavior, poses a hidden danger of greater HIV/AIDS transmission through sexual intercourse in the near future.

  9. Epistemic fault lines in biomedical and social approaches to HIV prevention

    PubMed Central

    2011-01-01

    This paper raises the question of how knowledge creation is organized in the area of HIV prevention and how this concatenation of expertise, resources, at-risk people and viruses shapes the knowledge used to impede the epidemic. It also seeks to trouble the discourses of biomedical pre-eminence in the field of HIV prevention by examining the claim for treatment as prevention, looking at evidence constructed through the biomedical frame and through the lens of the sociology of science. These questions lie within a larger socio-historical context of lagging worldwide attention and funding to prevention in the HIV area and, in particular, neglect of populations at greatest risk. Much contemporary HIV prevention research relies on a population science divided over an epistemic fault line from the communities and individuals who must make sense of the intrusion of a life-threatening disease into their pursuit of pleasure and intimacy. There are, nevertheless, lessons to be learned from prevention success stories among sex workers, injection drug users, and gay and bisexual men. The success stories point to a need for a robust social science agenda that examines: the ways that people are socially organized and networked; the popular strategies and folk wisdoms developed in the face of HIV risk; socio-historical movement of sexual and drug cultures; the dynamics of popular mobilization to advance health; the institutional sources of HIV discourses; and popular understandings of HIV technologies and messages.

    2014-01-01

    Various studies have reported that university students, who are mostly young people, rarely use existing HIV/AIDS preventive methods. Although studies have shown that young university students have a high degree of knowledge about HIV/AIDS and HIV modes of transmission, they are still not utilising the existing HIV prevention methods and still engage in risky sexual practices favourable to HIV. Some variables, such as awareness of existing HIV/AIDS prevention methods, have been associated with utilisation of such methods. The study aimed to explore factors that influence use of existing HIV/AIDS prevention methods among university students residing in a selected campus, using the Health Belief Model (HBM) as a theoretical framework. A quantitative research approach and an exploratory-descriptive design were used to describe perceived factors that influence utilisation by university students of HIV/AIDS prevention methods. A total of 335 students completed online and manual questionnaires. Study findings showed that the factors which influenced utilisation of HIV/AIDS prevention methods were mainly determined by awareness of the existing university-based HIV/AIDS prevention strategies. Most utilised prevention methods were voluntary counselling and testing services and free condoms. Perceived susceptibility and perceived threat of HIV/AIDS score was also found to correlate with HIV risk index score. Perceived susceptibility and perceived threat of HIV/AIDS showed correlation with self-efficacy on condoms and their utilisation. Most HBM variables were not predictors of utilisation of HIV/AIDS prevention methods among students. Intervention aiming to improve the utilisation of HIV/AIDS prevention methods among students at the selected university should focus on removing identified barriers, promoting HIV/AIDS prevention services and providing appropriate resources to implement such programmes.

  11. Condoms for the prevention of HIV transmission: cultural dimensions.

    PubMed

    Potts, M; Short, R V

    1989-01-01

    Humans being fundamentally polygamous, condoms should be recognized and promoted as central to an integrated approach for family planning, HIV prevention, and the control of sexually transmitted diseases. They must be more widely and effectively distributed and promoted in both more developed and developing nations. Available data on the ability of condoms to stem the transmission of HIV are limited, yet nonetheless indicative of condoms' general protective effect. Comparatively high prevalence and use of condoms are, however, found only in Japan, Sweden, Finland, Denmark, Singapore, and Trinidad and Tobago. Use in the U.S. is under that of a generation ago, while only extremely low levels are found throughout most of Africa, Asia, and South America. The industrialized nations of the West are most readily in the position of affording increased condom prevalence and use through increased manufacturing capacity and intensified promotion of moderate behavioral change among users. The nations of the 3rd World, however, lack the monetary and logistical resources to finance a rapid increase in condom prevalence, and are demanded to focus their energies more than ever where they are most needed, and expected to produce most significant impact. Up to $1 billion/year would be needed from donor agencies to meet universal need for condoms in Africa alone. Simple and cheap though condoms may be, such cost is too high to bear. The use of social marketing is therefore endorsed to target high-risk groups of populations as a means of maximizing resources for greatest potential impact. NGOs will play a major role in condom distribution, and should expect to work with, instead of through, ministries of health. PMID:2514745

    In 2006, the US Centers for Disease Control and Prevention issued recommendations supporting routine HIV testing in health care settings for all persons aged 13 to 64 years. Despite these recommendations, physicians are not offering HIV testing routinely. We apply a model that has previously identified 3 central, inter-related factors (knowledge-, attitude-, and behavior-related barriers) for why physicians do not follow practice guidelines in order to better understand why physicians are not offering HIV testing routinely. This model frames our review of the existing literature on physician barriers to routine HIV testing. Within the model, knowledge barriers include lack of familiarity or awareness of clinical recommendations, attitude barriers include lack of agreement with guidelines, while behavioral barriers include external barriers related to the guidelines themselves, to patients, or to environmental factors. Our review reveals that many physicians face these barriers with regards to implementing routine HIV testing. Several factors underscore the importance of determining how to best address physician barriers to HIV testing, including: provisions of the Affordable Care Act that are likely to require or incentivize major payers to cover HIV testing, evidence which suggests that a physician's recommendation to test for HIV is a strong predictor of patient testing behavior, and data which reveals that nearly 20% of HIV-positive individuals may be unaware of their status. In April 2013, the US Preventive Services Task Force released a recommendation supporting routine HIV testing; strategies are needed to help address ongoing physician barriers to testing.

    African-American young men who have sex with men and transgender persons are at elevated risk for HIV infection. House and Ball communities, networks of mostly African-American gay, bisexual, and transgender individuals who compete in modeling and dance, represent a prime venue for HIV prevention with these difficult-to-reach populations; however, little research exists on effective approaches to HIV prevention within these communities. Using a mixed-methods approach, the present study sought to document participation in HIV prevention activities of a sample from the Los Angeles House and Ball communities (n = 263) in order to inform future service development. While 80% of participants were tested for HIV within the past 6 months, only 26% report HIV prevention program attendance. House leaders recommend a holistic approach to HIV prevention, one that incorporates attention to social problems beyond HIV, including poverty, housing difficulties, and lack of job training.

    Getting to zero: zero new HIV infections, zero deaths from AIDS-related illness, zero discrimination is the theme of World AIDS Day 2012. Given the spread of the epidemic today, getting to zero may sound difficult, but significant progress is underway. The total annual loss for the entire country due to HIV is 7% of GDP, which exceeds India’s annual health expenditure in 2004. The additional loss due to loss of labor income and increased medical expenditure as measured by the external transfers, account for 5% of the country’s health expenditure and 0.23% of GDP. Given that the HIV incidence rate is only 0.27% in India, these losses are quite staggering. Despite the remarkable achievements in development of anti-retroviral therapies against HIV and the recent advances in new prevention technologies, the rate of new HIV infections continue to outpace efforts on HIV prevention and control. Thus, the development of a safe and effective vaccine for prevention and control of AIDS remains a global public health priority and the greatest opportunity to eventually end the AIDS pandemic.

    Background Sexually transmitted co-infections increase HIV infectiousness through local inflammatory processes. The prevalence of STI among people living with HIV/AIDS has implications for containing the spread of HIV in general and the effectiveness of HIV treatments for prevention in particular. Methods A systematic review of studies examining STI co-infections in people living with HIV/AIDS. The review focuses on STI contracted after becoming HIV infected. Electronic database and manual searches located clinical and epidemiological studies of STI that increase HIV infectiousness. Results Thirty seven studies of STI-HIV co-infection prevalence were located. Studies of adults living with HIV/AIDS from developed and developing countries reported STI rates for 46 different samples (33 samples had clinical/laboratory confirmed STI). The overall mean point-prevalence for confirmed STI was16.3% (SD = 16.4), and median 12.4% STI prevalence in people living with HIV/AIDS. The most common STI studied were Syphilis with median 9.5% prevalence, gonorrhea 9.5%, Chlamydia 5%, and Trichamoniasis 18.8% prevalence. STI prevalence was greatest at the time of HIV diagnosis, reflecting the role of STI in HIV transmission. Prevalence of STI among individuals receiving HIV treatment was not appreciably different from untreated persons. Conclusions The prevalence of STI in people infected with HIV suggests that STI co-infections could undermine efforts to use HIV treatments for prevention by increasing genital secretion infectiousness.

    The resumption of sexual activity after delivery is a key moment in the management of the risk of sexual HIV transmission within the couple for women who had been prenatally tested for HIV. In this study, we have investigated consistent condom use during the resumption of sexual activity and its evolution over time among women tested for HIV infection during pregnancy. We tested for HIV during pregnancy 546 HIV-infected and 393 HIV-negative women within the DITRAME Plus ANRS project in Abidjan; these women were followed-up for two years after delivery. Most HIV-negative women (96.7%) disclosed their HIV-test result to their partners, whereas only 45.6% of HIV-infected women did it (p<0.001). Partners of HIV-infected women were more likely to be tested for HIV before resuming sexual activity than partners of HIV-negative women (11.7% versus 7.4% p=0.054). Less than one third of both HIV-infected and HIV-negative women reported having systematically used condoms during the resumption of sexual activity. The proportions of HIV-infected and HIV-negative women having consistently used condom were respectively 26.2% and 19.8% (p=0.193) at 3 months post-partum, 12.1% and 15.9% (p=0.139) at 12 months post-partum, 8.4% and 10.6%, (p=0.302) at 18 months post-partum. In our study, although women had been prenatally tested for HIV and properly counselled on the sexual risk of HIV transmission, male partners were not tested for HIV before the resumption of sexual activity after delivery, very few couples were using condoms systematically and condom use was decreasing over time.

    Evidence that treating people with HIV early in infection prevents transmission to sexual partners has reframed HIV prevention paradigms. The resulting emphasis on HIV testing as part of prevention strategies has rekindled the debate as to whether laws that criminalise HIV transmission are counterproductive to the human rights-based public health response. It also raises normative questions about what constitutes 'safe(r) sex' if a person with HIV has undetectable viral load, which has significant implications for sexual practice and health promotion. This paper discusses a recent high-profile Australian case where HIV transmission or exposure has been prosecuted, and considers how the interpretation of law in these instances impacts on HIV prevention paradigms. In addition, we consider the implications of an evolving medical understanding of HIV transmission, and particularly the ability to determine infectiousness through viral load tests, for laws that relate to HIV exposure (as distinct from transmission) offences. We conclude that defensible laws must relate to appreciable risk. Given the evidence that the transmissibility of HIV is reduced to negligible level where viral load is suppressed, this needs to be recognised in the framing, implementation and enforcement of the law. In addition, normative concepts of 'safe(r) sex' need to be expanded to include sex that is 'protected' by means of the positive person being virally suppressed. In jurisdictions where use of a condom has previously mitigated the duty of the person with HIV to disclose to a partner, this might logically also apply to sex that is 'protected' by undetectable viral load.

    The objectives of this study were to describe knowledge, attitudes, and self-awareness, and to identify predictable factors affecting HIV/AIDS prevention among Thai university students. A cross sectional survey was conducted among 844 first-year university students using a validated, self-administered questionnaire as a research instrument. The questionnaire included items assessing knowledge, attitudes, self-awareness, and HIV/AIDS preventive behaviors. It was found that 22.4% of the subjects received various sexually provocative media. The university student's knowledge, attitudes, self-awareness, and preventive behaviors toward HIV/AIDS were at a high level. The results from the multiple regression analysis identified self-awareness, faculty, sex, sexual-risk score, income-per-month, GPA, and knowledge as significant independent predictors of HIV/AIDS preventive behaviors. These factors contributed to 36.9% of the explanation of HIV preventive behaviors, and the strongest predictor was found to be self-awareness. Scientific information, and useful and productive life skills are needed to educate the university students regarding the health consequences of HIV/AIDS. An integrated approach is strongly suggested for creating knowledge, attitudes, and awareness to control the spread of HIV/AIDS among young people. PMID:23413715

    Purpose of review We review the current state of evidence-based prevention strategies for reducing sexual transmission of HIV. The combined programmatic and scientific efforts through 2008 to reduce sexual transmission of HIV have failed to reduce substantially the global pandemic. Recent findings Prevention interventions to reduce HIV infection target behavioral, biomedical, and structural risk factors. Some of these prevention strategies have been evaluated in randomized clinical trials (RCTs) with HIV seroincidence endpoints. When RCTs are not feasible, a variety of observational and quasiexperimental research approaches can provide insight as to program effectiveness of specific strategies. Only five RCTs have demonstrated a notable decrease in sexually acquired HIV incidence. These include the Mwanza study of syndromic management of sexually transmitted diseases and three male circumcision trials in East Africa; a microbicide trial reported in 2009 shows substantial promise for the efficacy of PRO 2000 (0.5% gel). Summary The combined programmatic and scientific efforts to reduce sexual transmission of HIV have made incremental progress. New prevention tools are needed to stem the continued spread of HIV, though microbicides and vaccines will take many more years to develop, test, and deploy. Combination strategies of existing modalities should be tested to evaluate the potential for more proximate prevention benefits. PMID:19532063

    Young men who have sex with men (YMSM) are increasingly using mobile smartphone applications (“apps”), such as Grindr, to meet sex partners. A probability sample of 195 Grindrusing YMSM in Southern California were administered an anonymous online survey to assess patterns of and motivations for Grindr use in order to inform development and tailoring of smartphone-based HIV prevention for YMSM. The number one reason for using Grindr (29%) was to meet “hook ups.” Among those participants who used both Grindr and online dating sites, a statistically significantly greater percentage used online dating sites for “hook ups” (42%) compared to Grindr (30%). Seventy percent of YMSM expressed a willingness to participate in a smartphone app-based HIV prevention program. Development and testing of smartphone apps for HIV prevention delivery has the potential to engage YMSM in HIV prevention programming, which can be tailored based on use patterns and motivations for use.

    The past 2 decades have taught us that HIV prevention can work. We now have evidence from places as diverse as Senegal, Thailand, Uganda, and Australia that concerted HIV prevention efforts at the national level have resulted in the maintenance of low seroprevalence rates where they otherwise would have been expected to rise. We are beginning to observe declining rates of HIV prevalence and incidence in places and populations with historically high rates--for example, injection drug users in New York City. This trend points to the long-term impact of prevention efforts in those communities. The best of these efforts have been based on sound scientific research. As we move into the third decade of the AIDS epidemic, it is important to restate principles, acknowledge advances, and identify challenges and future directions in HIV prevention research.

    2010-01-01

    Background In South Africa, HIV prevalence among youth aged 15-24 is among the world's highest. Given the urgent need to identify effective HIV prevention approaches, this review assesses the evidence base for youth HIV prevention in South Africa. Methods Systematic, analytical review of HIV prevention interventions targeting youth in South Africa since 2000. Critical assessment of interventions in 4 domains: 1) study design and outcomes, 2) intervention design (content, curriculum, theory, adaptation process), 3) thematic focus and HIV causal pathways, 4) intervention delivery (duration, intensity, who, how, where). Results Eight youth HIV prevention interventions were included; all were similar in HIV prevention content and objectives, but varied in thematic focus, hypothesised causal pathways, theoretical basis, delivery method, intensity and duration. Interventions were school- (5) or group-based (3), involving in- and out-of-school youth. Primary outcomes included HIV incidence (2), reported sexual risk behavior alone (4), or with alcohol use (2). Interventions led to reductions in STI incidence (1), and reported sexual or alcohol risk behaviours (5), although effect size varied. All but one targeted at least one structural factor associated with HIV infection: gender and sexual coercion (3), alcohol/substance use (2), or economic factors (2). Delivery methods and formats varied, and included teachers (5), peer educators (5), and older mentors (1). School-based interventions experienced frequent implementation challenges. Conclusions Key recommendations include: address HIV social risk factors, such as gender, poverty and alcohol; target the structural and institutional context; work to change social norms; and engage schools in new ways, including participatory learning.

    Introduction As a group, transwomen in Peru have the highest prevalence of HIV (>20%) in the country, but they have little access to HIV prevention, testing and care services. Until recently, Peru's national HIV programme did not recognize transwomen and had remained essentially static for decades. This changed in December 2014, when the Ministry of Health expressed its commitment to improve programming for transwomen and to involve transwomen organizations by prioritizing the development of a “Targeted Strategy Plan of STIs/HIV/AIDS Prevention and Comprehensive Care for Transwomen.” Discussion A policy dialogue between key stakeholders – Peru's Ministry of Health, academic scientists, civil society, transgender leaders and international agencies – created the conditions for a change in Peru's national HIV policy for transwomen. Supported by the effective engagement of all sectors, the Ministry of Health launched a plan to provide comprehensive HIV prevention and care for transwomen. The five-year plan includes new national guidelines for HIV prevention, care and support, and country-level investments in infrastructure and equipment. In addition to new biomedical strategies, the plan also incorporates several strategies to address structural factors that contribute to the vulnerability of transwomen. We identified three key factors that created the right conditions for this change in Peru's HIV policy. These factors include (1) the availability of solid evidence, based on scientific research; (2) ongoing efforts within the transwomen community to become better advocates of their own rights; and (3) a dialogue involving honest discussions between stakeholders about possibilities of changing the nation's HIV policy. Conclusions The creation of Peru's national plan for HIV prevention and care for transwomen shows that long-term processes, focused on human rights for transwomen in Peru, can lead to organizational and public-policy change.

    HIV testing plays a critical role in preventing the spread of the virus and identifying infected individuals in need of care. Voluntary counseling and testing centers (VCTs) not only conduct testing but they also provide counseling. Since a proportion of people who test negative for HIV on their previous visit will return for retesting, the frequency of retesting and the characteristics of those who retest may provide insights into the efficacy of testing and counseling strategies. In this cross-sectional, retrospective study of 1,482 VCT clients in Croatia in 2010, 44.3% had been tested for HIV before. The rate of repeat HIV testing is lower in Croatia than in other countries. Men who have sex with men (MSM) clients, those with three or more sexual partners in the last 12 months, consistent condom users with steady partners, and intravenous drug users were more likely to be repeat testers. This finding suggests that clients presenting for repeat HIV testing are those who self-identify as being at a higher risk of infection. Our data showed that testing positive for HIV was not associated with repeat testing. However, the effects of repeat testing on HIV epidemiology needs to be explored. PMID:24705595

AUM programs have demonstrated limited efficacy in changing behaviors, promoted medically inaccurate information, and withheld life-saving information about risk reduction. A focus on AUM also undermined national efforts in Africa to create integrated youth HIV prevention programs. PEPFAR prevention efforts after 2008 shifted to science-based programming, however vestiges of AUM remain. Primary prevention programs within PEPFAR are essential and nations must be able to design HIV prevention based on local needs and prevention science. PMID:23327516

  7. Comparing HIV prevalence estimates from prevention of mother-to-child HIV transmission programme and the antenatal HIV surveillance in Addis Ababa

    2012-01-01

    Background In the absence of reliable data, antenatal HIV surveillance has been used to monitor the HIV epidemic since the late 1980s. Currently, routine data from Prevention of Mother-to-child HIV transmission (PMTCT) programmes are increasingly available. Evaluating whether the PMTCT programme reports provide comparable HIV prevalence estimates with the antenatal surveillance reports is important. In this study, we compared HIV prevalence estimates from routine PMTCT programme and antenatal surveillance in Addis Ababa with the aim to come up with evidence based recommendation. Methods Summary data were collected from PMTCT programmes and antenatal surveillance reports within the catchment of Addis Ababa. The PMTCT programme data were obtained from routine monthly reports from 2004 to 2009 and from published antenatal HIV surveillance reports from 2003 to 2009. Data were analysed using descriptive statistics. Results In Addis Ababa, PMTCT sites had increased from six in 2004 to 54 in 2009. The site expansion was accompanied by an increased number of women testing. There were marked increases in the rate of HIV testing following the introduction of routine opt-out HIV testing approach. Paralleling these increases, the HIV prevalence showed a steady decline from 10.0% in 2004 to 4.5% in 2009. There were five antenatal surveillance sites from 2003 to 2007 in Addis Ababa and they increased to seven by 2009. Four rounds of surveillance data from five sites showed a declining trend in HIV prevalence over the years. The overall antenatal surveillance data also showed that the HIV prevalence among antenatal attendees had declined from 12.4% in 2003 to 5.5% in 2009. The HIV prevalence estimates from PMTCT programme were 6.2% and 4.5% and from antenatal surveillance 6.1 and 5.5% in 2008 and 2009 respectively. Conclusions There were consistent HIV prevalence estimates from PMTCT programme and from antenatal surveillance reports. Both data sources showed a marked decline in

    In the United States, racial disparities in HIV/AIDS are stark. Although African Americans comprise an estimated 14% of the U.S. population, they made up 52% of new HIV cases among adults and adolescents diagnosed in 2009. Heterosexual transmission is now the second leading cause of HIV in the United States. African Americans made up a full two-thirds of all heterosexually acquired HIV/AIDS cases between 2005 and 2008. Few demonstrated efficacious HIV prevention interventions designed specifically for adult, African-American heterosexual men exist. Here, we describe the process used to design a theory-based HIV prevention intervention to increase condom use, reduce concurrent partnering, and increase HIV testing among heterosexually active African-American men living in high HIV prevalence areas of New York City. The intervention integrated empowerment, social identity, and rational choices theories and focused on four major content areas: HIV/AIDS testing and education; condom skills training; key relational and behavioral turning points; and masculinity and fatherhood.

    The biomedical intervention that has had a major impact on the natural history of HIV and on the global HIV epidemic is antiretroviral therapy (ART). However, the emergence of drug-resistant HIV, an inevitable consequence of increasing use of antiretroviral drugs, poses a major threat to ART success. At the turn of this century, access to life-saving ART was accelerated in low and middle-income countries with the Millennium Development Goal of 15 million individuals receiving ART by 2015 expected to be achieved. However, ART access needs to continue to expand to help bring HIV under control by 2030. The standard of care for people living with HIV in resource- limited settings differs dramatically compared to high-income countries, and not unexpectedly, ART rollout in these settings has resulted in an increase in acquired and transmitted drug resistance. Also of concern, the same drug classes used for ART have been approved or are being progressed for HIV prevention and drug resistance could mitigate their effectiveness for treatment and prevention. In the absence of an effective HIV vaccine and cure, it is imperative that the antiretroviral drug pipeline contains new classes of HIV inhibitors that are active against circulating drug-resistant strains. Studies to advance our fundamental understanding of HIV replication needs to continue, including the interplay between virus and host cell factors, to identify and characterize new drug targets for chemotherapeutic intervention.

    2011-01-01

    Within the national dialogue of HIV prevention strategies, relatively little consideration is given to the millions of women and girls affected by the criminal justice system either through their own incarceration or that of their partners. Yet statistics indicate that these women and girls are disproportionately infected or at risk for HIV and other sexually transmitted infections and much of this risk is directly related to the dynamics and circumstances that led to their incarceration or relationships with incarcerated men. As we look for the link between public health and correctional health within our National HIV/AIDS Strategy, it is imperative that the risks, obstacles, and opportunities facing women and girls affected by incarceration are brought into the discussion. Gender responsive HIV prevention policies and practices must be developed to address the unique risks and opportunities for these women and girls. This paper presents data on HIV risk and other health issues specific to this community of women and girls, discusses key factors for consideration when developing gender-responsive HIV strategies for these communities, and makes recommendations for inclusion in the National HIV/AIDS Strategy and other state and local HIV prevention efforts.

    This article reports a comprehensive national needs assessment of Latinos' access to HIV/AIDS prevention and education services in 14 cities throughout the United States and Puerto Rico. Interviews and focus groups were conducted with Latinos who were HIV-positive and at risk for HIV infection. The study explored risk behaviors, access to health care services, and exposure to HIV prevention messages. Differences in predictors of risk behaviors were noted by sex. For women, increased age, being married, foreign-born, and a U.S. resident, and having tested for HIV previously, were associated with reduced HIV/AIDS risk. Thematic analysis of qualitative findings revealed limited awareness of risk factors, and a need for culturally and linguistically appropriate, family-centered HIV/AIDS education incorporating Latino values. Findings were incorporated into culturally relevant brochures featuring vignettes and quotes. Brochures were distributed and evaluated by 71 community-based organizations (CBOs) in the U.S. and Latin America. Evaluators responded positively to the brochures, and Latino-serving organizations in 48 states now use them for HIV/AIDS prevention outreach and education. PMID:18157640

    Background HIV-1 has proved to infect regulatory T cells (Treg) modifying their phenotype and impairing their suppressive capacity. As Treg cells are a crucial component in the preservation of the immune homeostasis, we researched that the antiviral capacity of carboxilan dendrimers prevents the HIV-1 infection of Treg and their effects. The phenotype and suppressive capacity of Treg treated or non-treated with carbosilane dendrimers were studied by flow cytometry. Treated and non-treated Treg from healthy donors were infected with HIV-1NL4.3. The infection of Treg cells by HIV-1, and protective effect of two dendrimers were determined by measuring antigen p24gag in the supernatant of the culture and intracellular. Results The Treg cells were treated with cationic and anionic carbosilane dendrimers. The results showed that both dendrimers did not modify the phenotype and functionality of Treg cells compared with non- treated Treg cells. Anionic dendrimers showed high biocompatibility with normal activity of the Treg cells and in antiviral assays. These dendrimers were highly active against HIV-1 preventing the infection of Treg, and were able to protect the Treg from the Foxp3 downregulation induced by the HIV-1 infection. Conclusions This is the first work showing that the in vitro use of anionic dendrimers prevent the HIV-1 replication and the infection of expanded Treg cells in culture, which raises the possibility to use Treg cells therapeutically in HIV-1-infected subjects.

    Over the prior decade, structural change efforts have become an important component of community-based HIV prevention initiatives. However, these efforts may not succeed when structural change initiatives encounter political resistance or invoke conflicting values, which may be likely when changes are intended to benefit a stigmatized population. The current study sought to examine the impact of target population stigma on the ability of 13 community coalitions to achieve structural change objectives. Results indicated that coalitions working on behalf of highly stigmatized populations had to abandon objectives more often than did coalitions working for less stigmatized populations because of external opposition to coalition objectives and resultant internal conflict over goals. Those coalitions that were most successful in meeting external challenges used opposition and conflict as transformative occasions by targeting conflicts directly and attempting to neutralize oppositional groups or turn them into strategic allies; less successful coalitions working on behalf of stigmatized groups struggled to determine an appropriate response to opposition. The role of conflict transformation as a success strategy for working on behalf of stigmatized groups is discussed. PMID:21805217

    Evidence-based guidance regarding use of nearly all pharmaceuticals by pregnant and lactating women is limited. Models for performing research may assist in filling these knowledge gaps. Internationally, reproductive age women are at high risk of human immunodeficiency virus (HIV) acquisition. Susceptibility to HIV infection may be increased during pregnancy, and risk of maternal-child transmission is increased with incident HIV infection during pregnancy and lactation. A multidisciplinary meeting of experts was convened at the United States National Institutes of Health to consider paradigms for drug research in pregnancy and lactation applicable to HIV prevention. This report summarizes the meeting proceedings and describes a framework for research on candidate HIV prevention agent use during pregnancy and lactation that may also have broader applications to other pharmaceutical products.

    Injection drug use contributes to considerable global morbidity and mortality associated with human immunodeficiency virus (HIV) infection and AIDS and other infections due to blood-borne pathogens through the direct sharing of needles, syringes, and other injection equipment. Of ~16 million injection drug users (IDUs) worldwide, an estimated 3 million are HIV infected. The prevalence of HIV infection among IDUs is high in many countries in Asia and eastern Europe and could exacerbate the HIV epidemic in sub- Saharan Africa. This review summarizes important components of a comprehensive program for prevention of HIV infection in IDUs, including unrestricted legal access to sterile syringes through needle exchange programs and enhanced pharmacy services, treatment for opioid dependence (i.e., methadone and buprenorphine treatment), behavioral interventions, and identification and treatment of noninjection drug and alcohol use, which accounts for increased sexual transmission of HIV. Evidence supports the effectiveness of harm-reduction programs over punitive drug-control policies. PMID:20397939

    Abstract Thirty-day readmission rates, a widely utilized quality metric, are high among HIV-infected individuals. However, it is unknown how many 30-day readmissions are preventable, especially in HIV patients, who have been excluded from prior potentially preventable readmission analyses. We used electronic medical records to identify all readmissions within 30 days of discharge among HIV patients hospitalized at a large urban safety net hospital in 2011. Two independent reviewers assessed whether readmissions were potentially preventable using both published criteria and detailed chart review, how readmissions might have been prevented, and the phase of care deemed suboptimal (inpatient care, discharge planning, post-discharge). Of 1137 index admissions, 213 (19%) resulted in 30-day readmissions. These admissions occurred among 930 unique HIV patients, with 130 individuals (14%) experiencing 30-day readmissions. Of these 130, about half were determined to be potentially preventable using published criteria (53%) or implicit chart review (48%). Not taking antiretroviral therapy (ART) greatly increased the odds of a preventable readmission (OR 5.9, CI:2.4–14.8). Most of the preventable causes of readmission were attributed to suboptimal care during the index hospitalization. Half of 30-day readmission in HIV patients are potentially preventable. Increased focus on early ART initiation, adherence counseling, management of chronic conditions, and appropriate timing of discharge may help reduce readmissions in this vulnerable population.

    Social workers are often on the front lines of the HIV/AIDS epidemic – delivering prevention education and interventions, offering or linking individuals to HIV testing, and working to improve treatment access, retention, and adherence, especially among vulnerable populations. Individuals with substance use disorders face additional challenges to reducing sexual and drug risk behaviors, as well as barriers to testing, treatment, and antiretroviral therapy adherence. This paper presents current data on HIV transmission and research evidence on prevention and intervention with substance abusers and highlights how individual social workers can take advantage of this knowledge in practice and through adoption and implementation within organizations.

    The population within the criminal justice system suffers from various health disparities including HIV and hepatitis C virus (HCV). African American and Latino offenders represent the majority of the offender population. Evidence-based interventions to prevent HIV and HCV among criminal justice clients are scant and usually do not take cultural differences into account. Toward this end, this study describes the process of culturally adapting an HIV/HCV prevention intervention for Latino criminal justice clients in Miami, Florida, by using the ecological validity model. Recommendations for culturally adapting an intervention for Latinos include an emphasis on language and integrating cultural themes such as familism and machismo. PMID:27302706

    Researchers increasingly argue that poverty and gender inequality exacerbate the spread of HIV/AIDS and that economic empowerment can therefore assist in the prevention and mitigation of the disease, particularly for women. This paper critically evaluates such claims. First, we examine the promises and limits of integrated HIV/AIDS prevention and microfinance programs by examining the available evidence base. We then propose future research agendas and next steps that may help to clear current ambiguities about the potential for economic programs to contribute to HIV/AIDS risk reduction efforts.

  3. Men and women have specific needs that facilitate enrollment in HIV-prevention counseling

    Although reducing HIV risk is a primary motive for the design of HIV prevention interventions, the goals of the clients may be very different. Social theories of gender suggest that women, who often seek to resolve social and relational problems, may see HIV-prevention counseling as a mean of resolving partner violence. In contrast, men, who often worry about their physical strength, may seek to enroll in HIV-prevention programs when they experience physical symptoms unrelated to HIV. An unobtrusive study was conducted to observe enrollment in HIV risk-reduction counseling after measuring partner-violence complaints (e.g., feeling threatened or being hit), emotional complaints (e.g., fatigue or anxiety), and physical complaints (e.g., cardiovascular or digestive symptoms). The sample was a group of 350 participants, 70% clients from a state-health department in North Central Florida and 30% community members. Consistent with predictions, complaints of partner violence had a positive association with enrollment in women but not in men, whereas complaints about physical health had a positive association with enrollment in men, but not in women. Emotional complaints did not predict enrollment in either gender group. This study suggests that broad, gender-specific population needs must be competently addressed within HIV-prevention programs and may be strategically used to increase program enrollment.

    The current dominant model of HIV prevention intervention dissemination involves packaging interventions developed in one context, training providers to implement that specific intervention, and evaluating the extent to which providers implement it with fidelity. Research shows that providers rarely implement these programs with fidelity due to perceived incompatibility, resource constraints, and preference for locally generated solutions. In this study, we used the concept of "common factors," or broad constructs shared by most evidence-based HIV prevention interventions, to train service providers to develop their own programs. We recruited eight Ukrainian HIV prevention organizations from regions with HIV epidemics concentrated among people who inject drugs. We trained staff to identify HIV risk behaviors and determinants, construct behavior change logic models, and develop and manualize an intervention. We systematically reviewed each manual to assess intervention format and content and determine whether the program met intervention criteria as taught during training. All agencies developed programs that reflected common factors of effective behavior change HIV prevention interventions. Each agency's program targeted a unique population that reflected local HIV epidemiology. All programs incorporated diverse pedagogical strategies that focused on skill-building, goal-setting, communication, and empowerment. Agencies struggled to limit information dissemination and the overall scope and length of their programs. We conclude that training service providers to develop their own programs based on common elements of effective behavior change interventions can potentially transform existing processes of program development, implementation, and capacity building. Expanding this model will require committed training and support resources. PMID:27178497

    Indonesia is facing a growing HIV-epidemic that in many areas is driven by injecting drug use (IDU). IDUs underutilize health services, partly because of legal aspects which also cause that many are held in prison, where further HIV- transmission may take place. Most HIV-infected patients present with advanced HIV-AIDS and many deaths before starting antiretroviral treatment. The growing HIV-epidemic in Indonesia has socio-economical implications for individual patients as well as for the health system and for society. IMPACT, a multidisciplinary university-based program in Bandung, West-Java, integrates HIV-prevention and treatment, combining research and implementation. Biomedical, public health and sociobehavioral expertise is used for educational programs for adolescents; scaling-up HIV-testing, harm reduction strategies and care for HIV/AIDS in hospital, community and prison; and institutional as well as individual capacity building related to IDU and HIV/AIDS. It is expected that these activities can make a significant contribution to control of HIV-AIDS in the context of injecting drug use in West-Java and Indonesia as a whole. PMID:19920301

    Setting: One hundred and forty non-governmental organisations implementing human immunodeficiency virus (HIV) prevention programmes among clients, including people who inject drugs, prisoners, female sex workers, men who have sex with men and street children in Ukraine, 2010–2011. Objective: Among enrolled clients, to assess factors associated with HIV testing, HIV retesting within a year of initial testing and HIV seroconversion. Design: Retrospective cohort study involving record reviews. Results: Of 192 487 clients, 42 109 (22%) underwent an initial HIV test (22% were positive). Among HIV-negative clients at baseline, 10 858 (27%) were retested within a year: 317 (3%) of these were HIV-positive. HIV testing and retesting rates were lower among prisoners (0.3%) and others (street children and partners of those in risk groups, 6%), and those who did not receive counselling or services such as condom and needle distribution. Individuals who were not counselled were more likely to seroconvert. Conclusions: In this large cohort of high-risk groups from Eastern Europe, HIV testing was low and HIV sero-conversion was high. This is of public health concern, bringing into question the overall quality of counselling and how well it is tailored to the specific needs of various risk groups. Qualitative studies to understand the reasons for non-testing are urgently required for designing client-specific interventions. PMID:26399206

    We developed an interactive, customizable, Web-based program focused on the prevention of HIV, sexually transmitted infections, and hepatitis among youth. Results from a randomized, controlled trial with youth in treatment for substance use demonstrated that this Web-based tool, when provided as an adjunct to an educator-delivered prevention intervention, increased accurate prevention knowledge, increased intentions to carefully choose partners, and was perceived as significantly more useful relative to the educator-delivered intervention when provided alone. Results suggest this Web-based program may be effective and engaging and may increase the adoption of effective HIV and disease prevention science for youth. Limitations are discussed. PMID:21190405

    Purpose The incidence of sexually transmitted infections (STIs) and human immunodeficiency virus (HIV) is high among young Chilean women, and there are no STI or HIV prevention interventions available to them that incorporate technology. The purpose of this study was to investigate the preliminary efficacy of an Internet-based STI and HIV prevention intervention (I-STIPI) for Chilean young women on measures of STI- and HIV-related information, motivation, behavioral skills, and preventive behaviors. Design This is a pretest-posttest study. Forty young Chilean women between 18 and 24 years of age participated in an investigation of the I-STIPI’s preliminary efficacy on STI and HIV prevention-related outcomes between baseline and a postintervention assessment. The intervention consisted of four online modules. Data collection was conducted in Santiago, Chile. Paired-samples t test analysis was used to determine whether there were significant differences in each of the outcome variables. Findings After receiving I-STIPI, women reported a significant increase in levels of STI- and HIV-related knowledge, attitudes toward the use of condoms and perceived self-efficacy, and a reduction of risky sexual behaviors with uncommitted partners. Conclusions The I-STIPI showed promise as an Internet-based intervention that can reduce barriers to accessing preventive interventions and increase STI and HIV preventive behaviors in young Chilean women. Clinical Relevance The study provided important information about the ability of an Internet-based intervention to reduce young women’s risk factors and to provide positive preliminary efficacy on STI- and HIV-related outcomes. Internet-based interventions can eliminate many barriers to receiving prevention interventions and may prove to be cost effective. PMID:25410132

    Context Reducing HIV incidence in the United States and improving health outcomes for people living with HIV hinge on improving access to highly effective treatment and overcoming barriers to continuous treatment. Using laboratory tests routinely reported for HIV surveillance to monitor individuals’ receipt of HIV care and contacting them to facilitate optimal care could help achieve these objectives. Historically, surveillance-based public health intervention with individuals for HIV control has been controversial because of concerns that risks to privacy and autonomy could outweigh benefits. But with the availability of lifesaving, transmission-interrupting treatment for HIV infection, some health departments have begun surveillance-based outreach to facilitate HIV medical care. Methods Guided by ethics frameworks, we explored the ethical arguments for changing the uses of HIV surveillance data. To identify ethical, procedural, and strategic considerations, we reviewed the activities of health departments that are using HIV surveillance data to contact persons identified as needing assistance with initiating or returning to care. Findings Although privacy concerns surrounding the uses of HIV surveillance data still exist, there are ethical concerns associated with not using HIV surveillance to maximize the benefits from HIV medical care and treatment. Early efforts to use surveillance data to facilitate optimal HIV medical care illustrate how the ethical burdens may vary depending on the local context and the specifics of implementation. Health departments laid the foundation for these activities by engaging stakeholders to gain their trust in sharing sensitive information; establishing or strengthening legal, policy and governance infrastructure; and developing communication and follow-up protocols that protect privacy. Conclusions We describe a shift toward using HIV surveillance to facilitate optimal HIV care. Health departments should review the

    Men who have sex with men (MSM) in the Americas require targeted, combination HIV prevention approaches. We solicited client and provider perspectives on emerging prevention interventions including HIV pre-exposure prophylaxis (PrEP) and HIV self-tests through focus groups and in-depth interviews with 130 MSM and 41 providers across four sites: New York, San Francisco, Lima, and Rio de Janeiro. Among the MSM participants, we identified three prevention typologies: non-condom users, inconsistent condom users, and consistent condom users. Northern and Southern MSM differed in the variety of harm reduction strategies utilized: where U.S. MSM relied on condom use as well as disclosure and seroadaptive behaviors for prevention, condom use without disclosure or serostatus discussions was the norm in South America. Interest in new prevention technologies was shaped by the social context. U.S. MSM preferences differed by typology, such that non-condom users were interested in taking PrEP and using home HIV tests. MSM in Brazil, regardless of typology, were interested in exploring new prevention options. MSM in Peru demonstrated moderate interest but were less comfortable with adopting new strategies. MSM and providers’ opinions differed substantially with respect to new prevention options. Across sites, most providers were reticent to engage with new prevention options, though some NGO-based providers were more supportive of exploring new prevention tools. Both clients and providers will need to be engaged in developing integrated prevention strategies for MSM. PMID:25826246

    Religious leaders in Sri Lanka may have a high potential of contributing to HIV/AIDS prevention among the general public because of their social status. In order to assess their current HIV/AIDS-related knowledge and attitude and the possibility of becoming community advocates of HIV/AIDS prevention, we conducted a questionnaire survey among Buddhist, Hindu, Muslim and Christian leaders in Sri Lanka in 2009. There were limited correct responses about HIV/AIDS-related knowledge and attitudes toward people living with HIV/AIDS (PLHIV), and information regarding condoms, HIV testing and counselling were poorly understood. Although a condom was less acceptable as a part of HIV/AIDS prevention, they were willing to learn more about HIV/AIDS and expressed support for both PLHIV and HIV prevention activities. Their experiences, preparedness and willingness of HIV prevention activities were associated with age, knowledge and/or religious background. In conclusion, intensive and systematic learning opportunities should be provided to equip the religious leaders with overall HIV/AIDS knowledge to become key players for HIV/AIDS prevention in their communities.

    African American women are bearing an excess burden of HIV/AIDS, becoming infected at a rate 25 times that of White American women. This places African American girls at the highest risk for becoming infected with HIV/AIDS. Culturally appropriate prevention strategies are indicated to suppress this trend. Two qualitative research methods were used to evaluate a culture- and gender-based HIV prevention intervention: My Sister, Myself. Community action participatory research was used to engage the community in the development of the intervention for early-adolescent girls. Eight girls participated in the 8-week intervention. Data were collected about culture and gender identification, sexual health knowledge, and future intentions throughout the intervention. Focus groups and observation participation data revealed three major themes: "high aspirations," "needing to know the truth," and "internal, external, and eternal resources." Findings indicate promise for intervention strategies that utilize culture- and gender-based strategies for HIV/AIDS prevention with young girls. PMID:18955506

    Despite ongoing prevention efforts, young gay and bisexual men (YGBM) accounted for more than three fourths of all recent HIV infections. Furthermore, they continue to engage in high-risk sexual behaviors at alarming rates. Nowadays, families are beginning to emerge as important resources for these youth. However, the viewpoints of YGBM and their families are largely missing from HIV prevention research and intervention development. To address this gap, we solicited the opinions of YGBM and their parents as to why YGBM engage in unsafe sex and what might be done to help them avoid HIV. Participants discussed youth's sense of invulnerability, sexual arousal, parental disapproval, and lack of societal acceptance as contributors to unsafe sex. Participants called for gay-sensitive sex education and community programming as well as increased societal acceptance. Overall, respondents recommended interpersonal and structural-level interventions that emphasized the importance of reducing stigma as a key component of HIV prevention. PMID:26443796

    Background Project Accept is a community randomized, controlled trial to evaluate the efficacy of community mobilization, mobile testing, same-day results, and post-test support for the prevention of HIV infection in Thailand, Tanzania, Zimbabwe, and South Africa. We evaluated the accuracy of in-country HIV rapid testing and determined HIV prevalence in the Project Accept pilot study. Methods Two HIV rapid tests were performed in parallel in local laboratories. If the first two rapid tests were discordant (one reactive, one non-reactive), a third HIV rapid test or enzyme immunoassay was performed. Samples were designated HIV NEG if the first two tests were non-reactive, HIV DISC if the first two tests were discordant, and HIV POS if the first two tests were reactive. Samples were re-analyzed in the United States using a panel of laboratory tests. Results HIV infection status was correctly determined based on-in country testing for 2,236 (99.5%) of 2,247 participants [7 (0.37%) of 1,907 HIV NEG samples were HIV-positive; 2 (0.63%) of 317 HIV POS samples were HIV-negative; 2 (8.3%) of 24 HIV DISC samples were incorrectly identified as HIV-positive based on the in-country tie-breaker test]. HIV prevalence was: Thailand: 0.6%, Tanzania: 5.0%, Zimbabwe 14.7%, Soweto South Africa: 19.4%, Vulindlela, South Africa: 24.4%, (overall prevalence: 14.4%). Conclusions In-country testing based on two HIV rapid tests correctly identified the HIV infection status for 99.5% of study participants; most participants with discordant HIV rapid tests were not infected.

    2012-07-01

    There is growing optimism in the global health community that the HIV epidemic can be halted. After decades of relying primarily on behavior change to prevent HIV transmission, a second generation of prevention efforts based on medical or biological interventions such as male circumcision and preexposure prophylaxis--the use of antiretroviral drugs to protect uninfected, at-risk individuals--has shown promising results. This article calls for a third generation of HIV prevention efforts that would integrate behavioral, biological, and structural interventions focused on the social, political, and environmental underpinnings of the epidemic, making use of local epidemiological evidence to target affected populations. In this third wave, global programs should deliver HIV prevention services together with cost-effective interventions for reproductive health and for tuberculosis, malaria, and other diseases. Additionally, new efforts are needed to address gaps in HIV prevention research, evaluation, and implementation. Increased and sustained funding, along with evidence-based allocation of funds, will be necessary to accelerate the decline in new HIV infections. PMID:22778344

    2011-01-01

    Since the beginning of the epidemic, the protection of human rights has been an integral component in the response to Human Immunodeficiency Virus (HIV). The high degree of stigma and discrimination associated with acquired immune deficiency syndrome (AIDS) has made human rights protection not only a priority to ensure the rights of people living with and at-risk for HIV, but to address public health goals as well. Advances in understanding the impact of antiretroviral treatment on HIV prevention provide exciting opportunities and even a paradigm shift in terms of AIDS prevention. However, this potential cannot be reached unless the advancement of human rights is a primary component of treatment and prevention programme and policy development. The use of antiretroviral treatment as prevention reinforces the value of basic principles related to the dignity and agency of people living with HIV to participate in the design and implementation of programmes, to be informed and to make informed decisions about their health and lives, to be protected from harm, and to have opportunities to seek redress and accountability for abuses. The possibility of using HIV treatment as a prevention tool means that now, more than ever, legal reform and community empowerment and mobilisation are necessary to realize the rights and health of people affected by HIV.

    Given current constraints on universal treatment campaigns, recent advances in public health prevention initiatives have revitalized efforts to stem the tide of HIV transmission. Yet, despite a growing imperative for prevention—supported by the promise of behavioral, structural and biomedical approaches to lower the incidence of HIV—human rights frameworks remain limited in addressing collective prevention policy through global health governance. Assessing the evolution of rights-based approaches to global HIV/AIDS policy, this review finds that human rights have shifted from collective public health to individual treatment access. While the advent of the HIV/AIDS pandemic gave meaning to rights in framing global health policy, the application of rights in treatment access litigation came at the expense of public health prevention efforts. Where the human rights framework remains limited to individual rights enforced against a state duty bearer, such rights have faced constrained application in framing population-level policy to realize the public good of HIV prevention. Concluding that human rights frameworks must be developed to reflect the complementarity of individual treatment and collective prevention, this article conceptualizes collective rights to public health, structuring collective combination prevention to alleviate limitations on individual rights frameworks and frame rights-based global HIV/AIDS policy to assure research expansion, prevention access and health system integration.

    HIV-related stigma is a pervasive structural driver of HIV. With an HIV epidemic among young men who have sex with men (MSM) and transgender women (TG) in Thailand characterized as explosive, we conducted a cross-sectional survey among MSM and TG aged 18-30 years. From April-August 2013, participants recruited using venue-based sampling from gay entertainment sites and community-based organizations completed a tablet-assisted survey interview in Thai language. We conducted multiple logistic regression to assess correlations between HIV-related stigma (felt-normative, vicarious domains) and socio-demographic variables, HIV vulnerabilities (gay entertainment employment, sex work, forced sex history), and HIV prevention uptake (condom use, HIV testing, rectal microbicide acceptability). Among participants (n = 408), 54% identified as gay, 25% transgender, and 21% heterosexual. Two-thirds (65.7%) were employed at gay entertainment venues, 67.0% had more than three male partners (past month), 55.6% had been paid for sex, and 4.5% were HIV-positive. One-fifth (21.3%) reported forced sex. Most participants reported experiencing felt-normative and vicarious HIV-related stigma. Adjusting for socio-demographics, participants with higher total HIV-related stigma scores had significantly lower odds of HIV testing and rectal microbicide acceptability, and higher odds of having experienced forced sex. Both vicarious and felt-normative dimensions of HIV-related stigma were inversely associated with HIV testing and rectal microbicide acceptability. Our findings suggest that HIV-related stigma harms the health of HIV-negative MSM and TG at high risk for HIV infection. HIV-related interventions and research among young MSM and TG in Thailand should address multiple dimensions of HIV-related stigma as a correlate of risk and a barrier to accessing prevention.

    Background This paper presents findings from a qualitative investigation of ethical and participatory issues related to the conduct of biomedical HIV prevention trials among marginalized populations in Thailand. This research was deemed important to conduct, as several large-scale biomedical HIV prevention trials among marginalized populations had closed prematurely in other countries, and a better understanding of how to prevent similar trial closures from occurring in the future was desired. Methods In-depth key informant interviews were held in Bangkok and Chiang Mai, Thailand. Interviews were audio recorded, transcribed, translated and thematically analyzed. The Good Participatory Practice Guidelines for Biomedical HIV Prevention Trials (GPP) guided this work. Results Fourteen interviews were conducted: 10 with policymakers, academic and community-based researchers and trial staff and four with representatives of non-governmental organizations (NGOs). Suggested ways to improve ethical and participatory practice centered on standards of HIV prevention, informed consent, communication and human rights. In particular, the need to overcome language and literacy differences was identified. Key informants felt communication was the basis of ethical understanding and trust within biomedical HIV prevention trial contexts, and thus fundamental to trial participants' ability to exercise free will. Discussion Biomedical HIV prevention trials present opportunities for inclusive and productive ethical and participatory practice. Key informants suggested that efforts to improve practice could result in better relationships between research stakeholders and research investigative teams and by extension, better, more ethical participatory trials. This research took place in Thailand and its findings apply primarily to Thailand. However, given the universality of many ethical considerations, the results of this study can inform the improvement of ethical and participatory

    Certain safe over-the-counter (OTC) sexual lubricants such as Astroglide, KY Liquid, Replens, Vagisil, ViAmor, and Wet Stuff inhibit both cell-free HIV and the production of HIV by infected leukocytes in vitro even in the presence of seminal fluid. To identify which components of the lubricants were active against HIV, we tested five components (glycerin, methylparaben, propylparaben, polyquaternium-32, and propylene glycol). The paraben preservatives and propylene glycol in the lubricants did not inhibit HIV, while the common natural homeostatic metabolite, glycerin, and the thickener polyquaternium-32 did strongly inactivate infectious HIV and HIV-infected leukocytes. Activity against HIV and HIV-infected cells by glycerin was stable through 24 hours at 37 degrees C. Glycerin and polyquaternium-32 were active at minimum concentrations of approximately 2% and 0.01%, respectively--well within the highest FDA safety guidelines. Both active components disrupted infected leukocytes within 5 minutes which resulted in inhibition of infectious HIV production by infected leukocytes of greater than 25 to 100-fold. These components do not disrupt vaginal epithelial cells in vivo. These components also rapidly inactivate cell-free HIV by 10- to 30-fold. Thus, we may conclude that the active components of the OTC lubricants are glycerin and polyquaternium-32. Using these components, OTC sexual lubricants could be reformulated to optimize their anti-HIV activity. Furthermore, clinical trials of these lubricants and components seem to be indicated because of their FDA safety level, wide availability, and low cost. PMID:15786693

    India has the greatest number of HIV infections in Asia and the third highest total number of infected persons globally. Men who have sex with men (MSM) are considered by the Government of India's National AIDS Control Organization (NACO) a "core risk group" for HIV in need of HIV prevention efforts. However there is a dearth of information on the frequency of participation in HIV prevention interventions and subsequent HIV risk and other correlates among MSM in India. Recruited through peer outreach workers, word of mouth and snowball sampling techniques, 210 MSM in Chennai completed an interviewer-administered assessment, including questions about participating in any HIV prevention interventions in the past year, sexual risk taking, demographics, MSM identities, and other psychosocial variables. Bivariate and multivariable logistic regression procedures were used to examine behavioral and demographic correlates with HIV prevention intervention participation. More than a quarter (26%) of the sample reported participating in an HIV prevention intervention in the year prior to study participation. Participants who reported engaging in unprotected anal sex (UAS; odds ratio [OR] = 0.28; p = 0.01) in the 3 months prior to study enrollment were less likely to have participated in an HIV prevention program in the past year. MSM who were older (OR = 1.04; p = 0.05), kothis (feminine acting/appearing and predominantly receptive partners in anal sex) compared to panthis (masculine appearing, predominantly insertive partners; OR = 5.52, p = 0.0004), those with higher educational attainment (OR = 1.48, p = 0.01), being "out" about having sex with other men (OR = 4.03, p = 0.0001), and MSM who reported ever having been paid in exchange for sex (OR = 2.92, p = 0.001) were more likely to have reported participation in an HIV prevention intervention in the preceding year. In a multivariable model, MSM reporting UAS in the prior 3 months were less likely to have participated in

    If the transmission of human immunodeficiency virus (HIV) is to be prevented, the environment in which people live should predispose them to engage in and sustain safe behaviors. Too often in public health, the range of organizations that make up that environment are overlooked, and prevention strategies are limited to familiar medical and public health institutions. Improvement in public health does not occur in isolation, apart from the other institutions of society--and so it is with the HIV-AIDS epidemic. Education; business and labor; religion; government; voluntary, civic, and social organizations; and the media can all serve as facilitators or as barriers to creating the environment--at the national, regional, State, or local level--that will prevent and control the spread of HIV infection and AIDS and support the needs of those already infected. Collectively, they become a comprehensive HIV prevention network with access to and influence on the total public. One of the most significant benefits of this network is the multiplier effect on the limited resources of public health. Therefore, as part of its HIV and AIDS prevention strategy, the Centers for Disease Control (CDC) has developed national partnerships to involve the leadership of business, labor and industry, religious institutions and organizations, and voluntary organizations in HIV and AIDS prevention and service. Some of these partnerships are federally funded, others are not. The national partnership program described in this paper has produced increased resources for HIV education and services and has demonstrated the synergistic benefits resulting from public and private cooperation in addressing the HIV epidemic.

    The Joint United Nations Programme on HIV/AIDS (UNAIDS) recently updated its global targets for antiretroviral therapy (ART) coverage for HIV-positive persons under which 90 % of HIV-positive people are tested, 90 % of those are on ART, and 90 % of those achieve viral suppression. Treatment policy is moving toward treating all HIV-infected persons regardless of CD4 cell count-otherwise known as treatment as prevention-in order to realize the full therapeutic and preventive benefits of ART. Mathematical models have played an important role in guiding the development of these policies by projecting long-term health impacts and cost-effectiveness. To guide future policy, new mathematical models must consider the barriers patients face in receiving and taking ART. Here, we describe the HIV care cascade and ART delivery supply chain to examine how mathematical modeling can provide insight into cost-effective strategies for scaling-up ART coverage in sub-Saharan Africa and help achieve universal ART coverage.

    The relationship between intimate partner violence (IPV) and HIV risk is well documented, but few interventions jointly address these problems. We developed and examined the feasibility of an intervention to reduce HIV risk behaviors among 97 women seeking services for IPV from a community-based NGO in Johannesburg, South Africa. Two versions of the intervention (a 6-session group and a 1-day workshop) were implemented, both focusing on HIV prevention strategies integrated with issues of gender and power imbalance. Attendance was excellent in both intervention groups. Assessments were conducted at baseline, post-intervention and two-month follow-up to demonstrate the feasibility of an intervention trial. Women in both groups reported reductions in HIV misperceptions and trauma symptoms, and increases in HIV knowledge, risk reduction intentions, and condom use self-efficacy. The 6-session group showed greater improvements in HIV knowledge and decreases in HIV misperceptions in comparison to the 1-day workshop. The study demonstrated the feasibility and potential benefit of providing HIV prevention intervention to women seeking assistance for IPV. PMID:19826941

    Alcohol use disorders (AUDs) are highly prevalent among people living with HIV/AIDS (PLWHA) and are associated with increased HIV risk behaviors, suboptimal treatment adherence, and greater risk for disease progression. We used the ADAPT-ITT strategy to adapt an evidence-based intervention (EBI), the Holistic Health Recovery Program (HHRP+), that focuses on secondary HIV prevention and antiretroviral therapy (ART) adherence and apply it to PLWHA with problematic drinking. Focus groups (FGs) were conducted with PLWHA who consume alcohol and with treatment providers at the largest HIV primary care clinic in New Orleans, LA. Overall themes that emerged from the FGs included the following: (1) negative mood states contribute to heavy alcohol consumption in PLWHA; (2) high levels of psychosocial stress, paired with few adaptive coping strategies, perpetuate the use of harmful alcohol consumption in PLWHA; (3) local cultural norms are related to the permissiveness and pervasiveness of drinking and contribute to heavy alcohol use; (4) healthcare providers unanimously stated that outpatient options for AUD intervention are scarce, (5) misperceptions about the relationships between alcohol and HIV are common; (6) PLWHA are interested in learning about alcohol's impact on ART and HIV disease progression. These data were used to design the adapted EBI. PMID:26697216

    Past research suggests that as many as 50% of onward human immunodeficiency virus (HIV) transmissions occur during acute and recent HIV infection. It is clearly important to develop interventions which focus on this highly infectious stage of HIV infection to prevent further transmission in the risk networks of acutely and recently infected individuals. Project Protect tries to find recently and acutely infected individuals and prevents HIV transmission in their risk networks. Participants are recruited by community health outreach workers at community-based HIV testing sites and drug users’ community venues, by coupon referrals and through referrals from AIDS clinics. When a network with acute/recent infection is identified, network members are interviewed about their risky behaviors, network information is collected, and blood is drawn for HIV testing. Participants are also educated and given prevention materials (condoms, syringes, educational materials); HIV-infected participants are referred to AIDS clinics and are assisted with access to care. Community alerts about elevated risk of HIV transmission are distributed within the risk networks of recently infected. Overall, 342 people were recruited to the project and screened for acute/recent HIV infection. Only six index cases of recent infection (2.3% of all people screened) were found through primary screening at voluntary counseling and testing (VCT) sites, but six cases of recent infection were found through contact tracing of these recently infected participants (7% of network members who came to the interview). Combining screening at VCT sites and contact tracing the number of recently infected people we located as compared to VCT screening alone. No adverse events were encountered. These first results provide evidence for the theory behind the intervention, i.e., in the risk networks of recently infected people there are other people with recent HIV infection and they can be successfully located

    IMPORTANCE New data and therapeutic options warrant updated recommendations for the use of antiretroviral drugs (ARVs) to treat or to prevent HIV infection in adults. OBJECTIVE To provide updated recommendations for the use of antiretroviral therapy in adults (aged ≥18 years) with established HIV infection, including when to start treatment, initial regimens, and changing regimens, along with recommendations for using ARVs for preventing HIV among those at risk, including preexposure and postexposure prophylaxis. EVIDENCE REVIEW A panel of experts in HIV research and patient care convened by the International Antiviral Society-USA reviewed data published in peer-reviewed journals, presented by regulatory agencies, or presented as conference abstracts at peer-reviewed scientific conferences since the 2014 report, for new data or evidence that would change previous recommendations or their ratings. Comprehensive literature searches were conducted in the PubMed and EMBASE databases through April 2016. Recommendations were by consensus, and each recommendation was rated by strength and quality of the evidence. FINDINGS Newer data support the widely accepted recommendation that antiretroviral therapy should be started in all individuals with HIV infection with detectable viremia regardless of CD4 cell count. Recommended optimal initial regimens for most patients are 2 nucleoside reverse transcriptase inhibitors (NRTIs) plus an integrase strand transfer inhibitor (InSTI). Other effective regimens include nonnucleoside reverse transcriptase inhibitors or boosted protease inhibitors with 2 NRTIs. Recommendations for special populations and in the settings of opportunistic infections and concomitant conditions are provided. Reasons for switching therapy include convenience, tolerability, simplification, anticipation of potential new drug interactions, pregnancy or plans for pregnancy, elimination of food restrictions, virologic failure, or drug toxicities.

    Abstract Background: The challenge of identifying and recruiting U.S. women at elevated risk for HIV acquisition impedes prevention studies and services. HIV Prevention Trials Network (HPTN) 064 was a U.S. multisite, longitudinal cohort study designed to estimate HIV incidence among women living in communities with prevalent HIV and poverty. Venue-based sampling (VBS) methodologies and participant and venue characteristics are described. Methods: Eligible women were recruited from 10 U.S. communities with prevalent HIV and poverty using VBS. Participant eligibility criteria included age 18–44 years, residing in a designated census tract/zip code, and self-report of at least one high-risk personal and/or male sexual partner characteristic associated with HIV acquisition (e.g., incarceration history). Ethnography was conducted to finalize recruitment areas and venues. Results: Eight thousand twenty-nine women were screened and 2,099 women were enrolled (88% black, median age 29 years) over 14 months. The majority of participants were recruited from outdoor venues (58%), retail spaces (18%), and social service organizations (13%). The proportion of women recruited per venue category varied by site. Most participants (73%) had both individual and partner characteristics that qualified them for the study; 14% were eligible based on partner risk only. Conclusion: VBS is a feasible and effective approach to rapidly recruit a population of women at enhanced risk for HIV in the United States. Such a recruitment approach is needed in order to engage women most at risk and requires strong community engagement. PMID:24742266

    Purpose Placebo and randomization are important concepts that must be understood before youth can safely participate in HIV vaccine studies or other biomedical trials for HIV prevention. These concepts are central to the phenomenon of preventive misconception which may be associated with an increase in risk behavior among study participants related to mistaken beliefs. Persuasive messaging, traditionally used in the field of marketing, could enhance educational efforts associated with randomized clinical trials. Methods Two educational brochures were designed to increase knowledge about HIV vaccine clinical trials via 1 and 2-sided persuasive messaging. Through the Adolescent Medicine Trials Network, 120 youth were enrolled, administered a mock HIV vaccine trial consent, and then randomized to receive either no supplemental information or one of the two brochures. Results The 2-sided brochure group in which common clinical trial misconceptions were acknowledgedand then refuted had significantly higher scores on knowledge of randomization and interpretation of side effects than the consent-only control group, and willingness to participate in an HIV vaccine trial was not decreased with the use of this brochure. Conclusion Two sided persuasive messaging improves understanding of the concepts of randomization and placebo among youth who would consider participating in an HIV vaccine trial. Further evaluation of this approach should be considered for at-risk youth participating in an actual trial of a biomedical intervention for HIV prevention. PMID:24613097

    Congregations are well positioned to address HIV in their communities, but their response to HIV has been mixed. An emerging literature describes HIV programming in urban, predominantly black congregations, but population-based data remain limited. This study examined the levels of HIV prevention and counseling programs and associated factors (e.g., religious, organizational) by using data from a phone census of congregations in the Greater Cincinnati area (N = 447). Over 10 % of congregations (36 % of Black Protestant and 5–18 % of other types of congregations) offered HIV education/prevention alone or in combination with counseling or with counseling and testing. Path analysis results showed notable significant (p < 0.05) total effects of theology-polity on HIV prevention/counseling programs, but these effects were fully mediated by other factors, including other community work and racial composition. The levels of HIV programming in this study were high by national standards, but further outreach is needed in high-risk African American communities. PMID:23568226

  17. The 'loss of community' and other problems for sexual citizenship in recent HIV prevention.

    2008-03-01

    Increases in reported unsafe sex among gay men have been explained as resistance to HIV prevention, or most recently, with the idea that a hyper-individualization of sexual action contributes to the loss of sexual community. This turning in HIV prevention has come to focus on the sexual action of gay men with HIV through the frames of: sexual transgression, sometimes called 'barebacking'; and altruism. Adopting the perspective of sexual citizenship in connection with qualitative interviews, this paper considers how gay men with HIV account for their sexual practice in light of the dual discourse of transgression/altruism. The paper will argue that gay men with HIV are deeply aware of what transgression/altruism implies for their identities and sexual relations, indicating the continued salience of community for sexual practice. Further, in the circumstances of blaming in relation to the moral labour of safer sex, gay men with HIV are trying to work out a co-operative practice for HIV prevention based on self-care, a moderated altruism and the voluntary action of sexual partners.

    This article reviews current issues and advancements in social network approaches to HIV prevention and care. Social network analysis can provide a method to understand health disparities in HIV rates and treatment access and outcomes. Social network analysis is a value tool to link social structural factors to individual behaviors. Social networks provide an avenue for low cost and sustainable HIV prevention interventions that can be adapted and translated into diverse populations. Social networks can be utilized as a viable approach to recruitment for HIV testing and counseling, HIV prevention interventions, and optimizing HIV medical care and medication adherence. Social network interventions may be face-to-face or through social media. Key issues in designing social network interventions are contamination due to social diffusion, network stability, density, and the choice and training of network members. There are also ethical issues involved in the development and implementation of social network interventions. Social network analyses can also be used to understand HIV transmission dynamics.

    2015-01-01

    The effectiveness of antiretroviral regimes (ARVs) to reduce risk of HIV transmission from mother to child and as post-exposure prophylaxis has been known for almost two decades. Recent research indicates ARVs can also reduce the risk of HIV transmission via sexual intercourse in two other ways. With pre-exposure prophylaxis (PrEP), ARVs are used to reduce risk of HIV acquisition among persons who are HIV negative and significantly exposed to the virus. With treatment as prevention (TasP), ARVs are used to reduce risk of HIV transmission from persons who are already HIV positive. The development of these new prevention strategies raises a rationing problem: given the chronic shortage of ARVs for HIV-infected persons in need of treatment, is it ethically justified to allocate ARVs for PrEP and/or TasP? This article examines the intuitively appealing view that allocation of ARVs for treatment should be the highest priority, the use of ARVs for TasP should be a secondary priority, and that utilizing ARVs for PrEP would be unethical. I will argue that selective, evidence-based allocation of ARVs for prevention in certain cases could be ethically justified even when there is insufficient anti-retroviral access for all those needing it for treatment.

    This report summarizes published findings of a community-based organization in New York City that evaluated and demonstrated the efficacy of the Many Men, Many Voices (3MV) human immunodeficiency virus (HIV)/sexually transmitted disease (STD) prevention intervention in reducing sexual risk behaviors and increasing protective behaviors among black men who have sex with men (MSM). The intervention addressed social determinants of health (e.g., stigma, discrimination, and homophobia) that can influence the health and well-being of black MSM at high risk for HIV infection. This report also highlights efforts by CDC to disseminate this evidence-based behavioral intervention throughout the United States. CDC's Office of Minority Health and Health Equity selected the intervention analysis and discussion to provide an example of a program that might be effective for reducing HIV infection- and STD-related disparities in the United States. 3MV uses small group education and interaction to increase knowledge and change attitudes and behaviors related to HIV/STD risk among black MSM. Since its dissemination by CDC in 2004, 3MV has been used in many settings, including health department- and community-based organization programs. The 3MV intervention is an important component of a comprehensive HIV and STD prevention portfolio for at-risk black MSM. As CDC continues to support HIV prevention programming consistent with the National HIV/AIDS Strategy and its high-impact HIV prevention approach, 3MV will remain an important tool for addressing the needs of black MSM at high risk for HIV infection and other STDs.

    The present situation of the HIV/AIDS epidemic is very grim in China. The probability of China becoming a country with a high prevalence of HIV/AIDS cannot be excluded because there have been factors which promote the wide spread of HIV if we fail to take timely action to prevent it at the opportune moment. However, China's HIV prevention policy is inadequate. Health professionals and programmers believed that they could take a conventional public health approach to cope with the HIV epidemic. They simply ignored the fact that HIV infection is an epidemic so special that their approach is not effective to deter the epidemic. Many health professionals and programmers bypassed ethical issues that had emerged in the prevention of the HIV epidemic. Even some health educators, sexologists and officials believe that 'AIDS is the punishment for promiscuity', and this belief has led to discrimination and stigmatization of AIDS patients, HIV positive people, their family members and high risk groups. Although homosexuality is not illegal, the police can always find any reason to detain homosexuals. A difficult ethical issue is about the laws prohibiting prostitution and drug use in China which force prostitutes and intravenous drug users underground, giving them no chance to access information, education and the services needed to protect them. The dilemma facing China is whether to stay with a restrictive policy for the reason of ideology cleansing or to turn to a more supportive policy. It is necessary to have some change in the ethical framework to evaluate the action in HIV prevention. Tolerance should be the first ethical principle. PMID:11654786

    Family plays a key role in the prevention and intervention of drug abuse among children and teenagers. Information about drugs provides parents with the exact knowledge on how to demonstrate attitudes and healthy behaviours. Therefore, the present study tried to investigate the effect of preventive and interventional trainings on self-efficacy and attitudes of mothers covered by mental health facilitators (MHFs) in this regard. This interventional study used case and control groups/pretest-posttest design. Based on the inclusion criteria, randomized sampling, and sample size formulation, 150 qualified mothers were recruited. Eligible participants were randomly divided into two intervention and control groups. A researcher-designed and self-administered questionnaire was used to gather the required data. Six instructive, communicative oral sessions and individual interviews were held by the facilitators for case group members. After two months, attitudes and self-efficacy of the mothers toward drug abuse issues were measured again by the same questionnaire. The results showed that the difference in intervention and control group was significant in terms of increasing self-efficacy and modifying attitudes (p<0.001). Furthermore, the case group members reported less misconceptions, stigma, and ignorance toward those suffering from addiction. PMID:27241418

    There remains a profound need for innovative and effective interventions designed for young men who have sex with men (YMSM) generally, and racial and ethnic minority YMSM, YMSM living in rural communities, and low-income YMSM, particularly, to prevent HIV and improve health outcomes in the United States. This introduction to this theme issue, "Behavioral HIV Prevention Interventions for Diverse YMSM," of AIDS Education and Prevention identifies some of the research needs, priorities, and opportunities that emerged during a seminal NIMHD-sponsored workshop on HIV prevention behavioral interventions for diverse YMSM. It provides researchers, practitioners, and federal partners guidance in next steps to reduce the impact of the HIV epidemic among YMSM. The needs, priorities, and opportunities identified serve as a foundation to push both the science and the practice of HIV prevention forward. We recognize that considerably more research is needed, and this issue highlights intervention research-where we have been and where we should go. With the disparities faced by YMSM, we must act rapidly to do the work it will take to meet their prevention needs, reduce infections, and save lives. PMID:27244188

    Governments and donors are investing considerable resources on HIV prevention in order to scale up these services rapidly. Given the current economic climate, providers of HIV prevention services increasingly need to demonstrate that these investments offer good 'value for money'. One of the primary routes to achieve efficiency is to take advantage of economies of scale (a reduction in the average cost of a health service as provision scales-up), yet empirical evidence on economies of scale is scarce. Methodologically, the estimation of economies of scale is hampered by several statistical issues preventing causal inference and thus making the estimation of economies of scale complex. In order to estimate unbiased economies of scale when scaling up HIV prevention services, we apply our analysis to one of the few HIV prevention programmes globally delivered at a large scale: the Indian Avahan initiative. We costed the project by collecting data from the 138 Avahan NGOs and the supporting partners in the first four years of its scale-up, between 2004 and 2007. We develop a parsimonious empirical model and apply a system Generalized Method of Moments (GMM) and fixed-effects Instrumental Variable (IV) estimators to estimate unbiased economies of scale. At the programme level, we find that, after controlling for the endogeneity of scale, the scale-up of Avahan has generated high economies of scale. Our findings suggest that average cost reductions per person reached are achievable when scaling-up HIV prevention in low and middle income countries. PMID:25779621

  7. HIV risk behaviours among injecting drug users in Northeast India following scale-up of a targeted HIV prevention programme

    PubMed Central

    2011-01-01

    Background In the Northeast Indian states of Manipur and Nagaland there has been an ongoing HIV epidemic among injecting drug users (IDUs) since the mid-1990s. Project ORCHID is an Avahan-funded HIV prevention project that has been working in selected districts of Manipur and Nagaland since 2004. It supports local partner non-government organisations (NGOs) to deliver a range of harm reduction interventions, and currently reaches approximately 14,500 IDUs across the two states. To assess changes in HIV risk behaviours two Behavioural Tracking Surveys (BTS) were undertaken among IDUs in 2007 and 2009. Methods The BTS used respondent driven sampling (RDS) to recruit adult male IDUs (18 years of age and above) from Ukhrul and Chandel districts in Manipur, and Kiphire and Zunheboto districts in Nagaland. This paper reports on analysis of socio-demographics, drug use and injecting practices, sexual behaviour and condom use, knowledge of HIV, and exposure to interventions. Descriptive data were analysed using RDSAT, and odds ratios were calculated in SPSS. Results The proportion of IDUs reporting NOT sharing needles / syringes at last injection increased substantially in Ukhrul (59.6% to 91.2%) and Zunheboto (45.5% to 73.8%), remained high in Chandel (97.0% to 98.9%), and remained largely unchanged in Kiphire (63.3% to 68.8%). The use of condoms with regular partners was low in all districts at both time points. In Ukhrul, Kiphire and Zunheboto the proportion of IDUs using condoms during sexual intercourse with a casual partner increased substantially to approximately 70-85%, whilst in Chandel the increase was only marginal (57.4% to 63.6%). Exposure to NGO HIV prevention interventions was significantly associated (p<0.05) with lower odds of sharing needles during the previous month (Nagaland, OR=0.63; Manipur, OR 0.35). Conclusion Despite district-level differences, the results from this BTS study indicate that exposure to HIV prevention services, predominately

    This paper addresses how London gay men use the internet to meet sexual partners, or for e-dating. Based on qualitative interviews conducted face-to-face or via the internet, this research develops an account of how information technologies mediate the negotiation of identity and risk in connection with sexual practice. E-dating itself is a bricolage, or heterogeneous DIY practice of internet-based-communication (IBC). A central aspect of IBC is "filtering" in and out prospective e-dates based on the images and texts used to depict sexual identities. Interpretations and depictions of personal HIV risk management approaches in IBC are framed by the meanings of different identities, such as the stigma associated with being HIV positive. This paper argues for a sexualities perspective in a theory of network society. Further, HIV prevention in e-dating can potentially be addressed by considering the interplay of the HIV prevention imperatives associated with different HIV serostatus identities. There is a case for encouraging more explicit IBC about risk in e-dating and incorporating the expertise of e-daters in prevention activity. There is also a need to rethink traditional conceptions of risk management in HIV prevention to make space for the risk management bricolage of network society. PMID:16669808

    The Joint United National Programme on HIV/AIDS announced last year that Advantage 24, a Nonoxynol-9 (N-9) product, had been shown to prevent transmission of sexually transmitted diseases, including HIV, during heterosexual vaginal intercourse. Advantage 24 uses a low dose of N-9 with a bio-adhesive gel that forms a temporary barrier over the cervix. Optimism about the new contraceptive centers around the fact that it contains the lowest N-9 dosage of any product marketed in the U.S. Researchers found that high doses or frequent use of N-9 can irritate vaginal mucosa, causing small breaks or lesions in the vaginal lining, and thus increasing a woman's risk of HIV infection. In Advantage 24 studies, no high rates of vaginal irritation or abrasion were found among the women using the contraceptive compared to those using the placebo. However, the Centers for Disease Control and Prevention (CDC) will not promote N-9 as an HIV prevention alternative since they fear it may cause women to use higher doses, actually increasing their risk of infection. They also feel it may cause others to move away from condoms, the most effective choice to prevent HIV infection. Others argue that women deserve to know about every option available for HIV risk reduction and that not every method suits every woman. Phase III studies of Advantage 24 are underway in South Africa and Thailand. PMID:11363828

    Sexually explicit media (SEM) have been used in HIV-prevention advertisements to engage men who have sex with men (MSM) and to communicate content. These advertisements exist within larger discourses, including a dominant heteronormative culture and a growing homonormative culture. Cognizant of these hegemonic cultures, this analysis examined the acceptable level of sexual explicitness in prevention advertisements. Seventy-nine MSM participated in 13 online focus groups, which were part of a larger study of SEM. Three macro themes-audience, location, and community representation-emerged from the analysis, as did the influence of homonormativity on the acceptability of SEM in HIV-prevention messages.

    2011-10-01

    HIV prevention research has shifted to the evaluation of combination prevention programs whereby biomedical, behavioral, and structural interventions are implemented concurrently to maximize synergies among interventions. However, these kinds of combination prevention packages, particularly when implemented at scale, pose significant evaluation challenges, including how best to determine impact and how and whether to measure the effectiveness of component strategies. In addition, methodological challenges unique to HIV infection such as the absence of a reliable incidence assay, the lack of naive control groups, and no suitable surrogates further complicate rigorous evaluation. In this commentary, we discuss the key considerations for planning impact evaluations of combination HIV prevention programs in light of these challenges, including defining the evaluable package, determining which component programs require independent assessment of impact, choosing study designs with valid counterfactuals, selecting appropriate outcomes of interest, and the importance of mid-course program corrections.

    Background The Centers for Disease Control and Prevention recommends that sexually active men who have sex with men (MSM) in the United States test for human immunodeficiency virus (HIV) at least three times per year, but actual testing frequency is much less frequent. Though mHealth is a popular vehicle for delivering HIV interventions, there are currently no mobile phone apps that target MSM with the specific aim of building an HIV testing plan, and none that focuses on developing a comprehensive prevention plan and link MSM to additional HIV prevention and treatment resources. Previous research has suggested a need for more iterative feedback from the target population to ensure use of these interventions. Objective The purpose of this study is to understand MSM’s preferences for functionality, format, and design of a mobile phone-based HIV prevention app and to examine MSM’s willingness to use an app for HIV prevention. Methods We conducted focus group discussions with 38 gay and bisexual men, with two in-person groups in Atlanta, two in Seattle, and one online focus group discussion with gay and bisexual men in rural US regions. These discussions addressed MSM’s general preferences for apps, HIV testing barriers and facilitators for MSM, and ways that an HIV prevention app could address these barriers and facilitators to increase the frequency of HIV testing and prevention among MSM. During focus group discussions, participants were shown screenshots and provided feedback on potential app functions. Results Participants provided preferences on functionality of the app, including the type and delivery of educational content, the value of interactive engagement, and the importance of social networking as an app component. Participants also discussed preferences on how the language should be framed for the delivery of information, identifying that an app needs to be simultaneously fun and professional.

    High rates of smoking among persons living with HIV (PLWH) may reduce the effectiveness of HIV treatment and contribute to significant morbidity and mortality. Factors associated with smoking in PLWH include mental health comorbidity, alcohol and drug use, health-related quality of life, smoking among social networks and supports, and lack of access to care. PLWH smokers are at a higher risk of numerous HIV-associated infections and non-HIV related morbidity, including a decreased response to antiretroviral treatment, impaired immune functioning, reduced cognitive functioning, decreased lung functioning, and cardiovascular disease. Seventeen smoking cessation interventions were identified, of which seven were randomized controlled trials. The most effective studies combined behavioral and pharmacotherapy treatments that incorporated comprehensive assessments, multiple sessions, and cognitive-behavioral and motivational strategies. Smoking cessation interventions that are tailored to the unique needs of diverse samples and incorporate strategies to reduce the risk of relapse are essential to advancing health outcomes in PLWH.

    The HIV/AIDS pandemic continues to be a global health priority, with high rates of new HIV-1 infections persisting in young women. One HIV prevention strategy is topical pre-exposure prophylactics or microbicides, which are applied vaginally or rectally to protect the user from HIV and possibly other sexually transmitted infections. Vaginal microbicide delivery will be the focus of this review. Multiple nonspecific and specific antiretroviral microbicide products have been clinically evaluated, and many are in preclinical development. The events of HIV mucosal transmission and dynamics of the cervicovaginal environment should be considered for successful vaginal microbicide delivery. Beyond conventional vaginal formulations, intravaginal rings, tablets and films are employed as platforms in the hope to increase the likelihood of microbicide use. Furthermore, combining multiple antiretrovirals within a given formulation, combining a microbicide product with a vaginal device and integrating novel drug-delivery strategies within a microbicide product are approaches to successful vaginal-microbicide delivery.

    A deterministic mathematical model for the transmission dynamics of HIV infection in the presence of a preventive vaccine is considered. Although the equilibria of the model could not be expressed in closed form, their existence and threshold conditions for their stability are theoretically investigated. It is shown that the disease-free equilibrium is locally-asymptotically stable if the basic reproductive number R<1 (thus, HIV disease can be eradicated from the community) and unstable if R>1 (leading to the persistence of HIV within the community). A robust, positivity-preserving, non-standard finite-difference method is constructed and used to solve the model equations. In addition to showing that the anti-HIV vaccine coverage level and the vaccine-induced protection are critically important in reducing the threshold quantity R, our study predicts the minimum threshold values of vaccine coverage and efficacy levels needed to eradicate HIV from the community.

    The last few years have witnessed a renewed commitment to HIV prevention. The evidence to support the use of antiretroviral therapy (ART) for prevention of new HIV infection in the form of Pre-exposure prophylaxis (PrEP) among men who have sex with men, transgender, people who inject drugs, heterosexual men and women and HIV-1 serodiscordant couples, or treatment as prevention (TasP) for serodiscordant couples have also grown. The need to explore the possible use of ART for HIV prevention in Nigeria has become imperative in view of its high HIV burden and the current slow pace of effort to achieve the universal target of reducing its HIV incidence by 50%. While PrEP and TasP are welcome addendum to the existing HIV prevention armamentarium, it is still important to conduct a demonstration project to identify strategies that can facilitate access to PrEP and TasP taking cognizance of the peculiar local challenges with respect to ART and HIV prevention commodity access. The country has therefore drawn a roadmap for itself on how to introduce ART for use for HIV prevention as either PrEP or TasP. This paper discusses the three year national roadmap that would enable the country generated the needed scientific evidence as well as extensive community support for use of ART for HIV prevention in Nigeria. This process includes the conduct of modeling and formative studies, and the implementation of a 24 months demonstration project. The outcome of the demonstration project would inform plans for the scale up of pre-exposure prophylaxis (PrEP) access for population(s) at high risk for HIV infection in Nigeria. PMID:26050385

    Background Efforts at HIV prevention that focus on high risk places might be more effective and less stigmatizing than those targeting high risk groups. The objective of the present study was to assess risk behaviour patterns, signs of current preventive interventions and apparent gaps in places where the risk of HIV transmission is high and in communities with high HIV prevalence. Methods The PLACE method was used to collect data. Inhabitants of selected communities in Lusaka and Livingstone were interviewed about where people met new sexual partners. Signs of HIV preventive activities in these places were recorded. At selected venues, people were interviewed about their sexual behaviour. Peer educators and staff of NGOs were also interviewed. Results The places identified were mostly bars, restaurants or sherbeens, and fewer than 20% reported any HIV preventive activity such as meetings, pamphlets or posters. In 43% of places in Livingstone and 26% in Lusaka, condoms were never available. There were few active peer educators. Among the 432 persons in Lusaka and 676 in Livingstone who were invited for interview about sexual behaviour, consistent condom use was relatively high in Lusaka (77%) but low in Livingstone (44% of men and 34% of women). Having no condom available was the most common reason for not using one. Condom use in Livingstone was higher among individuals socializing in places where condoms always were available. Conclusion In the places studied we found a high prevalence of behaviours with a high potential for HIV transmission but few signs of HIV preventive interventions. Covering the gaps in prevention in these high exposure places should be given the highest priority. PMID:18218124

    HIV/AIDS prevention campaigns have been overshadowed by conflicting, competing, and contradictory views between those who support condom use as a last resort and those who are against it for fear of promoting sexual immorality. We argue that abstinence and faithfulness to one partner are the best available moral solutions to the HIV/AIDS pandemic. Of course, deontologists may argue that condom use might appear useful and effective in controlling HIV/AIDS; however, not everything that is useful is always good. In principle, all schools of thought and faith seem to agree on the question of faithfulness for married couples and abstinence for those who are not married. But they differ on condom use. On the ground, the situation is far more complex. We simply lack a single, entirely reliable way to resolve all disagreements regarding HIV/AIDS prevention strategies. PMID:19130297

    Infectious syphilis disproportionately affects African Americans living in poverty in metropolitan areas in the southeastern United States. In this population, where syphilis persists, the rates of HIV and AIDS are also persistently high. In an effort to facilitate the design of more effective prevention programs, the present investigation employed focus groups to obtain information from low-income African Americans concerning the determinants of high rates of syphilis and HIV/AIDS in their communities. The subjects were 36 African American men and women ages 18 to 56 residing in metropolitan Memphis and surrounding Shelby County, Tennessee. Overall, the authors found significant lack of awareness of the magnitude of HIV/AIDS and syphilis in African American communities and lack of knowledge about the etiology and transmission of syphilis. The investigation points to the important role of women and partnerships of community organizations in preventing the spread of HIV, syphilis, and other sexually transmitted diseases in this population.

    The terms bareback and bareback identity are increasingly being used in academic discourse on HIV/AIDS without clear operationalisation. Using in-depth, face-to-face interviews with an ethnically diverse sample of 120 HIV infected and uninfected men, mainly gay-identifying, and recruited online in New York City, this study explored respondents’ definitions of bareback sex, the role that intentionality and risk played in those definitions, and whether respondents identified as ‘barebackers’. Results showed overall agreement with a basic definition of bareback sex as condomless anal intercourse, but considerable variation on other elements. Any identification as barebacker appeared too loose to be of use from a public health prevention perspective. To help focus HIV-prevention efforts, we propose a re-conceptualisation that contextualises risky condomless anal intercourse and distinguishing between behaviours that are intentional and may result in HIV-primary transmission from those that are not.

    Inconsistent results in recent HIV prevention trials of pre-exposure prophylactic interventions may be due to heterogeneity in risk among study participants. Intervention effectiveness is most commonly estimated with the Cox model, which compares event times between populations. When heterogeneity is present, this population-level measure underestimates intervention effectiveness for individuals who are at risk. We propose a likelihood-based Bayesian hierarchical model that estimates the individual-level effectiveness of candidate interventions by accounting for heterogeneity in risk with a compound Poisson-distributed frailty term. This model reflects the mechanisms of HIV risk and allows that some participants are not exposed to HIV and, therefore, have no risk of seroconversion during the study. We assess model performance via simulation and apply the model to data from an HIV prevention trial. Copyright © 2016 John Wiley & Sons, Ltd. PMID:26869051

    The efficacy of a computer-based interactive multimedia HIV/AIDS prevention program for men with intellectual disability (ID) was examined using a quasi-experimental within-subjects design. Thirty-seven men with mild to moderate intellectual disability evaluated the program. The pretest and posttest instruments assessed HIV/AIDS knowledge (high-risk fluids, HIV transmission, and condom facts) and condom application skills. All outcome measures showed statistically significant gains from pretest to posttest, with medium to large effect sizes. In addition, a second study was conducted with twelve service providers who work with men with ID. Service providers reviewed the HIV/AIDS prevention program, completed a demographics questionnaire, and a program satisfaction survey. Overall, service providers rated the program highly on several outcome measures (stimulation, relevance, and usability). PMID:24871795

    Voluntary medical male circumcision (VMMC) is capable of reducing the risk of sexual transmission of HIV from females to males by approximately 60%. In 2007, the WHO and the Joint United Nations Programme on HIV/AIDS (UNAIDS) recommended making VMMC part of a comprehensive HIV prevention package in countries with a generalized HIV epidemic and low rates of male circumcision. Modeling studies undertaken in 2009-2011 estimated that circumcising 80% of adult males in 14 priority countries in Eastern and Southern Africa within five years, and sustaining coverage levels thereafter, could avert 3.4 million HIV infections within 15 years and save US$16.5 billion in treatment costs. In response, WHO/UNAIDS launched the Joint Strategic Action Framework for accelerating the scale-up of VMMC for HIV prevention in Southern and Eastern Africa, calling for 80% coverage of adult male circumcision by 2016. While VMMC programs have grown dramatically since inception, they appear unlikely to reach this goal. This review provides an overview of findings from the PLOS Collection "Voluntary Medical Male Circumcision for HIV Prevention: Improving Quality, Efficiency, Cost Effectiveness, and Demand for Services during an Accelerated Scale-up." The use of devices for VMMC is also explored. We propose emphasizing management solutions to help VMMC programs in the priority countries achieve the desired impact of averting the greatest possible number of HIV infections. Our recommendations include advocating for prioritization and funding of VMMC, increasing strategic targeting to achieve the goal of reducing HIV incidence, focusing on programmatic efficiency, exploring the role of new technologies, rethinking demand creation, strengthening data use for decision-making, improving governments' program management capacity, strategizing for sustainability, and maintaining a flexible scale-up strategy informed by a strong monitoring, learning, and evaluation platform.

    Vaginal HIV transmission accounts for the majority of new infections worldwide. Currently, multiple efforts to prevent HIV transmission are based on pre-exposure prophylaxis with various antiretroviral drugs. Here, we describe two novel nanoformulations of the reverse transcriptase inhibitor rilpivirine for pericoital and coitus-independent HIV prevention. Topically applied rilpivirine, encapsulated in PLGA nanoparticles, was delivered in a thermosensitive gel, which becomes solid at body temperature. PLGA nanoparticles with encapsulated rilpivirine coated the reproductive tract and offered significant protection to BLT humanized mice from a vaginal high-dose HIV-1 challenge. A different nanosuspension of crystalline rilpivirine (RPV LA), administered intramuscularly, protected BLT mice from a single vaginal high-dose HIV-1 challenge one week after drug administration. Using transmitted/founder viruses, which were previously shown to establish de novo infection in humans, we demonstrated that RPV LA offers significant protection from two consecutive high-dose HIV-1 challenges one and four weeks after drug administration. In this experiment, we also showed that, in certain cases, even in the presence of drug, HIV infection could occur without overt or detectable systemic replication until levels of drug were reduced. We also showed that infection in the presence of drug can result in acquisition of multiple viruses after subsequent exposures. These observations have important implications for the implementation of long-acting antiretroviral formulations for HIV prevention. They provide first evidence that occult infections can occur, despite the presence of sustained levels of antiretroviral drugs. Together, our results demonstrate that topically- or systemically administered rilpivirine offers significant coitus-dependent or coitus-independent protection from HIV infection. PMID:26271040

    Introduction Currently, Tanzania's HIV prevalence is 5.7%. Gender inequality and Gender Based Violence (GBV) are among factors fuelling the spread of HIV in Tanzania. This study was conducted to assess universal access to HIV prevention services among GBV survivors in Iringa and Dar-es-Salaam where HIV prevalence is as high as 14.7% and 9% respectively compared to a national average of 5.7%. Methods In 2010, a mixed methods study using triangulation model was conducted in Iringa and Dar-es-Salaam regions to represent rural and urban settings respectively. Questionnaires were administered to 283 randomly selected survivors and 37 health providers while 28 in-depth interviews and 16 focus group discussions were conducted among various stakeholders. Quantitative data was analyzed in SPSS by comparing descriptive statistics while qualitative data was analyzed using thematic framework approach. Results Counseling and testing was the most common type of HIV prevention services received by GBV survivors (29%). Obstacles for HIV prevention among GBV survivors included: stigma, male dominance culture and fear of marital separation. Bribery in service delivery points, lack of confidentiality, inadequate GBV knowledge among health providers, and fear of being involved in legal matters were mentioned to be additional obstacles to service accessibility by survivors. Reported consequences of GBV included: psychological problems, physical trauma, chronic illness, HIV infection. Conclusion GBV related stigma and cultural norms are obstacles to HIV services accessibility. Initiation of friendly health services, integration of GBV into HIV services and community based interventions addressing GBV related stigma and cultural norms are recommended. PMID:23467278

    2014-01-01

    Introduction Although biomedical HIV prevention efforts have seen a number of recent promising developments, behavioural interventions have often been described as failing. However, clear lessons have been identified from past efforts, including the need to address influential social, economic and legal structures; to tailor efforts to local contexts; and to address multiple influencing factors in combination. Despite these insights, there remains a pervasive strategy to try to achieve sexual behaviour change through single, decontextualized, interventions or sets of activities. With current calls for structural approaches to HIV as part of combination HIV prevention, though, there is a unique opportunity to define a structural approach to HIV prevention as one which moves beyond these past limitations and better incorporates our knowledge of the social world and the lessons from past efforts. Discussion A range of interlinked concepts require delineation and definition within the broad concept of a structural approach to HIV. This includes distinguishing between “structural factors,” which can be seen as any number of elements (other than knowledge) which influence risk and vulnerability, and “structural drivers,” which should be reserved for situations where an empirically established relationship to a target group is known. Operationalizing structural approaches similarly can take different paths, either working to alter structural drivers or alternatively working to build individual and community resilience to infection. A “structural diagnostic approach” is further defined as the process one undertakes to develop structural intervention strategies tailored to target groups. Conclusions For three decades, the HIV prevention community has struggled to reduce the spread of HIV through sexual risk behaviours with limited success, but equally with limited engagement with the lessons that have been learned about the social realities shaping patterns of

    As the search for more effective HIV prevention strategies continues, increased attention is being paid to the potential role of cash transfers in prevention programming in sub-Saharan Africa. To date, studies testing the impact of both conditional and unconditional cash transfers on HIV-related behaviours and outcomes in sub-Saharan Africa have been relatively small-scale and their potential feasibility, costs and benefits at scale, among other things, remain largely unexplored. This article examines elements of a successful cash transfer program from Latin America and discusses challenges inherent in scaling-up such programs. The authors attempt a cost simulation of a cash transfer program for HIV prevention in South Africa comparing its cost and relative effectiveness--in number of HIV infections averted--against other prevention interventions. If a cash transfer program were to be taken to scale, the intervention would not have a substantial effect on decreasing the force of the epidemic in middle- and low-income countries. The integration of cash transfer programs into other sectors and linking them to a broader objective such as girls' educational attainment may be one way of addressing doubts raised by the authors regarding their value for HIV prevention.

    Antiretroviral therapy (ART) improves the health of people living with HIV and can reduce infectiousness, preventing HIV transmission. The potential preventive benefits of ART are undermined by beliefs that it is safe to have condomless sex when viral load is below levels of detection (infectiousness beliefs and risk perceptions). In this study, we hypothesized that infectiousness beliefs and HIV transmission risk perceptions would prospectively predict people living with HIV engaging in more condomless sex with HIV-negative and unknown HIV status sex partners. Sexually active HIV-positive men (n = 538, 76 %) and women (n = 166, 24 %) completed computerized interviews of sexually transmitted infection (STI) symptoms and diagnoses, unannounced pill counts for medication adherence, medical chart-abstracted HIV viral load, and 28 daily cell-phone-delivered prospective sexual behavior assessments. Results showed that a total of 313 (44 %) participants had engaged in condomless sex with HIV-negative/unknown status sex partners, and these individuals demonstrated higher rates of STI symptoms and diagnoses. Two-thirds of participants who had condomless sex with HIV-negative/unknown status partners had not disclosed their HIV status. Multivariable logistic regression models showed that beliefs regarding viral load and HIV infectiousness and perceptions of lower risk of HIV transmission resulting from HIV viral suppression predicted condomless sex with potentially uninfected partners over and above sex behaviors with HIV-positive partners and STI symptoms/diagnoses. Interventions that address HIV status disclosure and aggressively treat STI in sexually active people living with HIV should routinely accompany the use of HIV treatments as prevention.

    After 30 years we are still struggling to address a devastating HIV pandemic in which over 25 million people have died. In 2010, an estimated 34 million people were living with HIV, around 70% of whom live in sub-Saharan Africa. Furthermore, in 2009 there were an estimated 1.2 million new HIV-associated TB cases, and tuberculosis (TB) accounted for 24% of HIV-related deaths. By the end of 2010, 6.6 million people were taking antiretroviral therapy (ART), around 42% of those in need as defined by the 2010 World Health Organization (WHO) guidelines. Despite this achievement, around 9 million people were eligible and still in need of treatment, and new infections (approximately 2.6 million in 2010 alone) continue to add to the future caseload. This combined with the international fiscal crisis has led to a growing concern regarding weakening of the international commitment to universal access and delivery of the Millennium Development Goals by 2015. The recently launched UNAIDS/WHO Treatment 2.0 platform calls for accelerated simplification of ART, in line with a public health approach, to achieve and sustain universal access to ART, including maximizing the HIV and TB preventive benefit of ART by treating people earlier, in line with WHO 2010 normative guidance. The potential individual and public health prevention benefits of using treatment in the prevention of HIV and TB enhance the value of the universal access pledge from a life-saving initiative, to a strategic investment aimed at ending the HIV epidemic. This review analyzes the gaps and summarizes the evidence regarding ART in the prevention of HIV and TB. PMID:21999771

    Gay male university students less than 25 years old were studied to determine whether they had changed their sexual activity patterns to reduce the risk of HIV infection. Most had not established sexual behavior patterns typical of the older gay men who had been studied in earlier research. Although most of the participants surveyed were concerned about HIV infection, some did engage in risky sexual behavior. The risk-reduction strategies most often used were having fewer sexual partners and being more selective in choosing partners. Future HIV-prevention interventions must be designed to address the needs of this generation of gay men. PMID:1506566

    Background HIV is hyperendemic in Swaziland with a prevalence of over 25% among those between the ages of 15 and 49 years old. The HIV response in Swaziland has traditionally focused on decreasing HIV acquisition and transmission risks in the general population through interventions such as male circumcision, increasing treatment uptake and adherence, and risk-reduction counseling. There is emerging data from Southern Africa that key populations such as female sex workers (FSW) carry a disproportionate burden of HIV even in generalized epidemics such as Swaziland. The burden of HIV and prevention needs among FSW remains unstudied in Swaziland. Methods A respondent-driven-sampling survey was completed between August-October, 2011 of 328 FSW in Swaziland. Each participant completed a structured survey instrument and biological HIV and syphilis testing according to Swazi Guidelines. Results Unadjusted HIV prevalence was 70.3% (n = 223/317) among a sample of women predominantly from Swaziland (95.2%, n = 300/316) with a mean age of 21(median 25) which was significantly higher than the general population of women. Approximately one-half of the FSW(53.4%, n = 167/313) had received HIV prevention information related to sex work in the previous year, and about one-in-ten had been part of a previous research project(n = 38/313). Rape was common with nearly 40% (n = 123/314) reporting at least one rape; 17.4% (n = 23/314)reported being raped 6 or more times. Reporting blackmail (34.8%, n = 113/314) and torture(53.2%, n = 173/314) was prevalent. Conclusions While Swaziland has a highly generalized HIV epidemic, reconceptualizing the needs of key populations such as FSW suggests that these women represent a distinct population with specific vulnerabilities and a high burden of HIV compared to other women. These women are understudied and underserved resulting in a limited characterization of their HIV prevention, treatment, and care needs and

    Beliefs concerning the spread of the human immunodeficiency virus (HIV) and preventive behaviors were examined in a sample of 351 sexually active Scottish teenagers. A postal questionnaire, including measures of variables specified by the health belief model (HBM) and preventive intentions, was employed. The relation between HBM measures and reported endorsement of HIV-preventive intentions was investigated. Results indicated that, in general, respondents intended to use condoms with new sexual partners. The majority also intended to carry condoms if they thought they might have sex with a new partner and to ask potential partners about their previous sexual history. Multiple-regression analyses showed that measures of health beliefs, gender, age, sexual experience, and previous condom use accounted for 17.8% to 24.3% of the variance in reported preventive intentions. Perceived barriers to preventive behaviors were found to be important predictors. However, the overall pattern of results raised questions concerning the adequacy of the HBM as a model of the determinants of HIV-preventive intentions, and the need for an extended model is discussed. Separate analyses were conducted for men and women and for 16- and 18-year-olds, and the implications for modeling intention formation in these subgroups are considered. The relevance of these findings to HIV-preventive campaigns is also discussed. PMID:1286655

    Intimate partner violence (IPV) has a bidirectional relationship with HIV infection. Researchers from the Rakai Health Sciences Program (RHSP), an HIV research and services organization in rural Uganda, conducted a combination IPV and HIV prevention intervention called the Safe Homes and Respect for Everyone (SHARE) Project between 2005 and 2009. SHARE was associated with significant declines in physical and sexual IPV and overall HIV incidence, and its model could be adopted as a promising practice in other settings. In this article we describe how SHARE's IPV-prevention strategies were integrated into RHSP's existing HIV programming and provide recommendations for replication of the approach. PMID:26086189

    Pre-exposure prophylaxis (PrEP), in which HIV uninfected persons with ongoing HIV risk use antiretroviral medications as chemoprophylaxis against sexual HIV acquisition, is a promising new HIV prevention strategy. Proof-of-concept that PrEP, as oral or vaginal topical tenofovir-based products, protects against sexual HIV acquisition has been demonstrated in clinical trials conducted among men who have sex with men and heterosexual men and women. The degree of HIV protection in these trials was strongly related to the level of adherence to PrEP. Many questions are yet unanswered--including how to motivate uptake of and sustain adherence to PrEP for HIV prevention, how much PrEP use is enough to achieve HIV protection, and the potential of "next-generation" PrEP agents to improve on this effective technology.

    Plasmacytoid dendritic cells (pDC) poorly replicate human immunodeficiency virus type 1 (HIV-1) but efficiently transfer HIV-1 to adjacent CD4 T lymphocytes. We found that coculture with T lymphocytes downregulates SAMHD1 expression, enhances HIV-1 replication, and increases pDC maturation and alpha interferon (IFN-α) secretion. HIV-1 transfer to T lymphocytes is inhibited by broadly neutralizing antibody VRC01 with efficiency similar to that of cell-free infection of T lymphocytes. Interestingly, prevention of HIV-1 transmission by VRC01 retains IFN-α secretion. These results emphasize the multiple functions of VRC01 in protection against HIV-1 acquisition. PMID:24965460

    This paper traces the commonly believed three phases of the HIV/AIDs epidemic in China from the early 1980s to the present time and reviews how the Chinese Government and NGOs are dealing with the crisis. Transmission routes for HIV infection in China are thought to be via IDUs, blood plasma donors, sexual contacts and from mother-to-child transmissions. The author examined interventions for HIV/ AIDS prevention tried in other countries that could provide useful lessons learned and discussed how they could be adapted or replicated in China. While recognising the need for the treatment of HIV positive persons and AIDS patients, this paper is limited to suggesting a number of proven strategic interventions to prevent new HIV infections in China among the "general population", adolescents in schools, sex workers and their clients, injecting drug users, and, prevention of mother to child transmission of HIV/AIDS to stem the epidemic. An extensive literature search of articles in published academic journals, published and unpublished documents of international agencies and development NGOs and media reports was conducted for data source to this paper. Internet search engines such as ProQuest, PubMed, Google and Yahoo search engines were used as well as hard copies of reports and internal documents available at the UNFPA Country Technical Services Team's Office in Bangkok tapped for information.

    Using the theory and concepts of health promotion, this paper proposes a logic model for HIV/AIDS prevention and control which provides a structure for describing planned actions and predicted impacts/outcomes from comprehensive HIV prevention interventions. The potential usefulness of the model is examined by reviewing the evolution of HIV prevention and management in China, drawing on evidence from interventions reported from a mixture of study designs and formats. It reports that HIV interventions in China can be considered in two distinctive phases, before and after 2003 when China commenced its 'official' response to the HIV epidemic. The logic model was useful in comparing actions taken over these two periods highlighting the importance of political leadership in distinguishing between the two phases, and the continuing importance of systematic and broadly based public education and communication. We conclude that the logic model can not only be used as a planning model, but can also be applied retrospectively to assess successes and failures in national and local responses to HIV in complex social settings.

    With the progressive increase in life-expectancy of human immunodeficiency virus (HIV)-positive patients in the "highly active antiretroviral therapy" (HAART) era, co-morbidities, particularly cardiovascular (CV) diseases (CVD) are emerging as an important concern. The pathophysiology of CVD in this population is complex, due to the interaction of classical CV risk factors, viral infection and the effects of antiretroviral therapy (ARV). The role of ARV drugs in HIV is double edged. While these drugs reduce systemic inflammation, an important factor in CV development, they may at the same time be proatherogenic by inducing dyslipidemia, body fat redistribution and insulin resistance. In these patients primary prevention is challenging, considering the lower median age at which acute coronary syndromes occur. Furthermore prevention is still limited by the lack of robust evidence-based, HIV-specific recommendations. Therefore we performed a comprehensive evaluation of the literature to analyze current knowledge on CVD prevalence in HIV-infected patients, traditional and HIV-specific risk factors and risk stratification, and to summarize the recommendations for primary prevention of CVD in this HIV population.

    Gay families are constructed support networks that gay, bisexual, and transgender individuals of color form, often in response to societal marginalization and rejection from biological families. Research on these family structures has been scarce, with little focus on the experience of African American gay family networks in the South. The current grounded theory qualitative study focused on the experiences of 10 African American male and transgender individuals between the ages of 18 and 29 from gay families in the Mid-South, and explored the ways these families addressed safe-sex issues and human immunodeficiency virus (HIV) risk prevention. Results revealed that families can play a role in either increasing HIV risk (e.g., ignoring HIV issues, encouraging such unsafe behaviors as exchanging sex for money or drugs, stigmatizing HIV-positive people) or decreasing it (e.g., intensive, family-level prevention efforts at safe-sex practices and family support for HIV treatment adherence). The potential of these family networks for HIV prevention and adherence efforts is considered. PMID:24992185

    HIV protease inhibitors are key components of HIV antiretroviral therapies, which are fundamental in the treatment of HIV infection. However, the protease inhibitors are well-known to induce metabolic dysfunction which can in turn escalate the complications of HIV, including HIV associated neurocognitive disorders. As experimental and epidemiological data support a therapeutic role for adiponectin in both metabolic and neurologic homeostasis, this study was designed to determine if increased adiponectin could prevent the detrimental effects of protease inhibitors in mice. Adult male wild type (WT) and adiponectin-overexpressing (ADTg) mice were thus subjected to a 4-week regimen of lopinavir/ritonavir, followed by comprehensive metabolic, neurobehavioral, and neurochemical analyses. Data show that lopinavir/ritonavir-induced lipodystrophy, hypoadiponectinemia, hyperglycemia, hyperinsulinemia, and hypertriglyceridemia were attenuated in ADTg mice. Furthermore, cognitive function and blood-brain barrier integrity were preserved, while loss of cerebrovascular markers and white matter injury were prevented in ADTg mice. Finally, lopinavir/ritonavir caused significant increases in expression of markers of brain inflammation and decreases in synaptic markers in WT, but not in ADTg mice. Collectively, these data reinforce the pathophysiologic link from metabolic dysfunction to loss of cerebrovascular and cognitive homeostasis; and suggest that preservation and/or replacement of adiponectin could prevent these key aspects of HIV protease inhibitor-induced toxicity in clinical settings.

    Unprotected anal sex has long been recognized as a risk factor for HIV transmission among men who have sex with men (MSM). In Africa, however, general denial of MSM existence and associated stigma discouraged research. To address this gap in the literature, partners conducted the first behavioral surveys of MSM in Kenya. The first study was to assess HIV risk among MSM in Nairobi, and the second study a pre-post intervention study of male sex workers in Mombasa. The 2004 behavioral survey of 500 men in Mombasa revealed that MSM were having multiple sexual partners and failed to access appropriate prevention counseling and care at Kenya clinics. A 2006 capture-recapture enumeration in Mombasa estimated that over 700 male sex workers were active, after which a pre-intervention baseline survey of 425 male sex workers was conducted. Awareness of unprotected anal sex as an HIV risk behavior and consistent condom use with clients was low, and use of oil-based lubricants high. Based on this information, peer educators were trained in HIV prevention, basic counseling skills, and distribution of condoms and lubricants. To assess impact of the interventions, a follow-up survey of 442 male sex workers was implemented in 2008. Exposure to peer educators was significantly associated with increased consistent condom use, improved HIV knowledge, and increased use of water-based lubricants. These results have provided needed information to the Government of Kenya and have informed HIV prevention interventions. PMID:24753921

    Background Worldwide, an in Chile, the number of women living with HIV is increasing. Depression is considered a factor that interferes with HIV prevention. Depression may reach 41% among low income Chilean women. Depressed people are less willing to participate in behaviors that protect them against HIV. Objectives To analyze the impact of Mano a Mano-Mujer (MM-M) on depressive symptoms among Chilean women. Methods A quasi-experimental design was used to test the impact of MM-M, an HIV prevention intervention. The research was conducted in Santiago- Chile, a total of 400 women participated in the study (intervention group, n = 182; control group, n = 218). The intervention was guided by the social-cognitive model and the primary health model. The intervention consists of six two-hour sessions delivered in small groups. Sessions covered: HIV prevention, depression, partner's communication, and substance abuse. Face to face interviews were conducted at baseline and at 3 months follow-up Results At 3 months post-intervention, Chilean women who participated in MM-M significantly decreased their reported depressive symptoms. Conclusions MM-M provided significant benefits for women's depression symptoms. This study offers a model that address depression, a risk factor for HIV. It uses nurses as leaders for the screening of depressive symptoms and as facilitators of community interventions. PMID:22452388

    2015-05-01

    Social scientific and public health literature on National Institutes of Health-funded HIV behavioural prevention science often assumes that this body of work has a strong biomedical epistemological orientation. We explore this assumption by conducting a systematic content analysis of all NIH-funded HIV behavioural prevention grants for men who have sex with men between 1989 and 2012. We find that while intervention research strongly favours a biomedical orientation, research into the antecedents of HIV risk practices favours a sociological, interpretive and structural orientation. Thus, with respect to NIH-funded HIV prevention science, there exists a major disjunct in the guiding epistemological orientations of how scientists understand HIV risk, on the one hand, and how they engineer behaviour change in behavioural interventions, on the other. Building on the extant literature, we suggest that the cause of this disjunct is probably attributable not to an NIH-wide positivist orientation, but to the specific standards of evidence used to adjudicate HIV intervention grant awards, including randomised controlled trials and other quantitative measures of intervention efficacy.

    The Joint United Nations Programme on HIV/AIDS (UNAIDS) recently updated its global targets for antiretroviral therapy (ART) coverage for HIV-positive persons under which 90% of HIV-positive people are tested, 90% of those are on ART, and 90% of those achieve viral suppression. Treatment policy is moving toward treating all HIV-infected persons regardless of CD4 cell count—otherwise known as treatment as prevention—in order to realize the full therapeutic and preventive benefits of ART. Mathematical models have played an important role in guiding the development of these policies by projecting long-term health impacts and cost-effectiveness. To guide future policy, new mathematical models must consider the barriers patients face in receiving and taking ART. Here, we describe the HIV care cascade and ART delivery supply chain to examine how mathematical modeling can provide insight into cost-effective strategies for scaling-up ART coverage in sub-Saharan Africa and help achieve universal ART coverage.

    Contact with the criminal justice system, including incarceration, is a common experience for many people living with HIV/AIDS. Optimism has recently been expressed that correctional facilities could be important locations for Treatment-as-Prevention (TasP)-based initiatives. We review recent findings regarding the effect of incarceration on patterns of HIV transmission, testing, treatment initiation and retention. We found that the prevalence of HIV infection among incarcerated individuals remains higher than analogous non-incarcerated populations. Recent studies have shown that voluntary HIV/AIDS testing is feasible in many correctional facilities, although the number of previously undiagnosed individuals identified has been modest. Studies have implied enhanced linkage to HIV/AIDS treatment and care in jails in the United States was associated with improvements in the HIV cascade of care. However, for many individuals living with HIV/AIDS, exposure to the correctional system remains an important barrier to retention in HIV/AIDS treatment and care. Future research should evaluate structural interventions to address these barriers and facilitate the scale-up of TasP-based efforts among individuals living in correctional settings. PMID:24962285

    Trade-offs may exist between investments to promote health system strengthening, such as investments in facilities and training, and the rapid scale-up of HIV/AIDS services. We analyzed trends in expenditures to support the prevention of mother-to-child transmission of HIV in Kenya under the President's Emergency Plan for AIDS Relief (PEPFAR) from 2005 to 2010. We examined how expenditures changed over time, considering health system strengthening alongside direct treatment of patients. We focused on two organizations carrying out contracts under PEPFAR: the Elizabeth Glaser Pediatric AIDS Foundation and FHI360 (formerly Family Health International), a nonprofit health and development organization. We found that the average unit expenditure, or the spending on goods and services per mother living with HIV who was provided with antiretroviral drugs, declined by 52 percent, from $567 to $271, during this time period. The unit expenditure per mother-to-infant transmission averted declined by 66 percent, from $7,117 to $2,440. Meanwhile, the health system strengthening proportion of unit expenditure increased from 12 percent to 33 percent during the same time period. The analysis suggests that PEPFAR investments in prevention of mother-to-child transmission of HIV in Kenya became more efficient over time, and that there was no strong evidence of a trade-off between scaling up services and investing in health systems.

    Objective. To investigate barriers and correlates of the use of HIV prevention services and HIV testing behaviors among men who have sex with men in Chongqing. Methods. Three consecutive cross-sectional surveys provided demographic, sexual behavior, HIV/syphilis infection, HIV prevention service, and testing behavior data. Results. Of 1239 participants, 15.4% were infected with HIV, incidence was 12.3 per 100 persons/year (95% CI: 9.2–15.3), 38% of the participants reported ever having unprotected insertive anal sex, 40% ever received free condom/lubricants in the past year, and 27.7% ever obtained free sexually transmitted infection examination/treatment in the past year. Multivariable logistic regression revealed that lower levels of HIV/AIDS related stigmatizing/discriminatory attitudes, full-time jobs, and sex debut with men at a younger age were independently associated with use of free condom/lubricants. Large social networks, higher incomes, and sexual debut with men at a younger age were associated with use of any HIV prevention and HIV testing services. Lower levels of stigmatizing/discriminatory attitudes were also associated with HIV testing. Fearing needles and being unaware of the venues for testing were top barriers for testing service utilization. Conclusion. It is imperative to address HIV/AIDS related stigmatizing/discriminatory attitudes and other barriers while delivering intervention and testing services. PMID:24783195

    Background Although emerging Treatment as Prevention models can be effective in reducing HIV incidence among high-risk populations, many HIV infected individuals remain undiagnosed or fail to engage in HIV care. Methods This study examined the factors associated with HIV testing and care among a population of substance using female sex workers. Results Recent HIV testing was associated with higher education level, having a regular health care provider or clinic, recent crack use, and higher sexual risk behaviors; HIV treatment utilization was associated with higher levels of social support, having a regular health care provider or clinic, housing stability and insurance coverage. Qualitative data revealed HIV-related stigma, denial, social isolation, and substance use as barriers to HIV testing and treatment; social support and accessibility of services were key enablers. Conclusions Improving HIV testing and linkage to treatment among female sex workers will require structural initiatives to reduce stigma and increase service seeking support. PMID:25130245

    Background Black men who have sex with men (BMSM) in the United States are at highest risk for HIV infection and are at high risk for limited health service utilization. We describe HIV health center (HHC) affiliation network patterns and their potential determinants among urban BMSM. Methods The Men’s Assessment of Social and Risk Network instrument was utilized to elicit HHC utilization as reported by study respondents recruited through respondent driven sampling. 204 BMSM were systematically recruited from diverse venues in Chicago, Illinois in 2010. A 2-mode data set was constructed that included study participants and 9 diverse HHCs. Associations between individual level characteristics and HHC utilization were analyzed using Multiple Regression Quadratic Assignment Procedure (MRQAP). Visualization analyses included computation of HHC centrality and faction membership. Results High utilization of HHCs (45.9%-70.3%) was evident among BMSM; 44.4% who were HIV infected. MRQAP revealed that age, social network size and HIV status were associated with HHC affiliation patterns (coef. 0.13-0.27; all p<0.05). With the exception of one HHC, HHCs offering HIV prevention services to HIV-infected participants occupied peripheral positions within the network of health centers. High-risk HIV-uninfected participants affiliated most with an HHC that offers only treatment services. Conclusions Sub-categories of BMSM in this sample affiliated with HHCs that may not provide appropriate HIV prevention services. Using 2-mode data, public health authorities may be better able to match prevention services to BMSM need; in particular HIV prevention services for high-risk HIV-uninfected men and HIVprevention for positives” services for HIV-infected men.

    Women continue to be at special risk for HIV acquisition due to a complex mix of biological, behavioural, structural, cultural and social factors, with unacceptable rates of new infection. Scientific advances over the past decade have highlighted the use of antiretroviral (ARV) drugs as pre-exposure prophylaxis (PrEP) to prevent HIV acquisition (sexually, parenterally and vertically) and ARV treatment (ART) for HIV-positive patients to prevent onward transmission (treatment as prevention – TasP). This paper reviews the evidence base for PrEP and TasP, describes new products in development and the need to translate research findings into programmes with impact at the population level.

    Rapid changes in China over the past two decades have led to significant problems associated with population migration and changing social attitudes, including a growing sex industry and concurrent increases in STIs and HIV. This article reports results of an exploratory study of microbicide acceptability and readiness and current HIV prevention efforts among female sex workers in two rural and one urban town in Hainan and Guangxi Provinces in southern China. The study focused on these women’s knowledge and cultural understandings of options for protecting themselves from exposure to STIs and HIV, and the potential viability and acceptability of woman-initiated prevention methods. We report on ethnographic elicitation interviews conducted with women working within informal sex-work establishments (hotels, massage and beauty parlors, roadside restaurants, boarding houses). We discuss implications of these findings for further promotion of woman-initiated prevention methods such as microbicides and female condoms among female sex workers in China. PMID:17599276

    Introduction HIV incidence remains high among young women in sub-Saharan Africa in spite of scale-up of HIV testing, behavioural interventions, antiretroviral treatment and medical male circumcision. There is a critical need to critique past approaches and learn about the most effective implementation of evidence-based HIV prevention strategies, particularly emerging interventions such as pre-exposure prophylaxis (PrEP). Discussion Women in sub-Saharan Africa are at increased risk of HIV during adolescence and into their 20s, in part due to contextual factors including gender norms and relationship dynamics, and limited access to reproductive and sexual health services. We reviewed behavioural, behavioural economic and biomedical approaches to HIV prevention for young African women, with a particular focus on the barriers, opportunities and implications for implementing PrEP in this group. Behavioural interventions have had limited impact in part due to not effectively addressing the context, broader sexual norms and expectations, and structural factors that increase risk and vulnerability. Of biomedical HIV prevention strategies that have been tested, daily oral PrEP has the greatest evidence for protection, although adherence was low in two placebo-controlled trials in young African women. Given high efficacy and effectiveness in other populations, demonstration projects of open-label PrEP in young African women are needed to determine the most effective delivery models and whether women at substantial risk are motivated and able to use oral PrEP with sufficient adherence to achieve HIV prevention benefits. Conclusions Social marketing, adherence support and behavioural economic interventions should be evaluated as part of PrEP demonstration projects among young African women in terms of their effectiveness in increasing demand and optimizing uptake and effective use of PrEP. Lessons learned through evaluations of implementation strategies for delivering oral Pr

    Female sex workers (FSWs) who work as peer outreach workers in HIV prevention programs are drawn from poor socio-economic groups and consider outreach work, among other things, as an economic activity. Yet, while successful HIV prevention outcomes by such programs are attributed in part to the work of peers who have dense relations with FSW communities, there is scant discussion of the economic implications for FSWs of their work as peers. Using observational data obtained from an HIV prevention intervention for FSWs in south India, we examined the economic benefits and costs to peers of doing outreach work and their implications for sex workers’ economic security. We found that peers considered their payment incommensurate with their workload, experienced long delays receiving compensation, and at times had to advance money from their pockets to do their assigned peer outreach work. For the intervention these conditions resulted in peer attrition and difficulties in recruitment of new peer workers. We discuss the implications of these findings for uptake of services, and the possibility of reaching desired HIV outcomes. Inadequate and irregular compensation to peers and inadequate budgetary outlays to perform their community-based outreach work could weaken peers’ relationships with FSW community members, undermine the effectiveness of peer-mediated HIV prevention programs and invalidate arguments for the use of peers.

    As part of a larger study to examine the feasibility and acceptability of a couples-based HIV-prevention intervention, we conducted formative in-depth interviews with 10 couples to explore topics such as challenges in practising safer sex, HIV-prevention strategies, gender power and violence, and issues of trust and infidelity. In this study, both men and women perceived infidelity as ubiquitous in their social context and were therefore unable to discuss HIV risk and prevention without suspicions of infidelity in their own relationship. This impacted couples’ ability openly and effectively to discuss strategies to prevent HIV and thus may have contributed to the limited uptake of HIV-prevention strategies, such as condom use and HIV testing. The contentious nature of safe-sex discussions placed both members of the couple at a higher risk for HIV acquisition within the partnership. This study sheds light on how existing relationship norms in South Africa influence HIV-prevention communication within couples and suggests that new ways of approaching conflictual issues such as mistrust and infidelity are vital in order for HIV-prevention programmes to succeed.

    Background: Commercial sex plays an increasingly important role in China’s growing HIV and sexually transmitted infection (STI) epidemics. In China, street-based sex workers (SSWs) are a subgroup of female sex workers with a particularly high risk of HIV/STI infections but are neglected in responses to HIV. This study assesses changes in HIV voluntary counseling and testing (VCT) utilization and high-risk sexual behaviors following a three-month HIV preventive intervention among SSWs in Chongqing, China. Methods: A three-month intervention was conducted by a team of peer educators, outreach workers from community-based organizations and health professionals. It mainly included distribution of free pamphlets and condoms and delivery of onsite and clinic-based VCT. Cross-sectional surveys were conducted prior to (n = 100) and immediately following (n = 112) the intervention to assess its impact. In-depth interviews were conducted among 12 SSWs after the intervention to further explore potential barriers to HIV prevention. Results: The intervention significantly increased SSWs’ participation in VCT (from 2.0%–15.2%, P < 0.001). Despite participants’ improved HIV-related knowledge level (from 24.0%–73.2%, P < 0.001), there were minimal changes in the levels of condom use with clients. Qualitative research revealed that fear of police arrest and stigma were the main barriers to VCT utilization. Low condom use was associated with family financial constraints, inadequate power in condom negotiation, low awareness and misconceptions of HIV infection risks. Conclusion: HIV intervention improved VCT utilization and knowledge but we did not observe an increase in condom use after this short intervention. SSWs faced substantial economic, social and environmental barriers to VCT utilization and condom use. PMID:25602971

    Despite the Mozambique government's efforts to curb human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS), national prevalence is 11.5% and support is needed to expand HIV-related services and improve program quality. Positive prevention (PP) programs, which prioritize HIV prevention with people living with HIV and AIDS (PLHIV), have been recognized as an important intervention for preventing new HIV infections. To address this, an evidence-based PP training intervention was implemented with HIV healthcare providers in Mozambique. This study focuses on the acceptability and feasibility of a PP intervention in HIV clinics from the healthcare provider perspective. In-depth interviews were conducted with 31 healthcare providers from three provinces who participated in PP trainings in Mozambique. Interview data were coded using content analysis. Study data suggest that healthcare providers found PP acceptable, feasible to implement in their HIV work in clinic settings, and valued this strategy to improve HIV prevention. The PP training also led providers to feel more comfortable counseling their patients about prevention, with a more holistic approach that included HIV testing, treatment and encouraging PLHIV to live positively. While overall acceptance of the PP training was positive, several barriers to feasibility surfaced in the data. Patient-level barriers in
