Background Black men who have sex with men (MSM) in the United States (US) are affected by HIV at disproportionate rates compared to MSM of other race/ethnicities. Current HIV incidence estimates in this group are needed to appropriately target prevention efforts. Methods From July 2009 to October 2010, Black MSM reporting unprotected anal intercourse with a man in the past six months were enrolled and followed for one year in six US cities for a feasibility study of a multi-component intervention to reduce HIV infection. HIV incidence based on HIV seroconversion was calculated as number of events/100 person-years. Multivariate proportional hazards modeling with time-dependent covariates was used to identify correlates of HIV acquisition. Results Of 1,553 Black MSM enrolled, 1,164 were HIV-uninfected at baseline and included in follow-up. Overall annual HIV incidence was 3.0% (95% confidence interval (CI): 2.0, 4.4%) and 5.9% among men ≤30 years old (95% CI: 3.6, 9.1%). Men ≤30 years old reported significantly higher levels of sexual risk and were more likely to have a sexually transmitted infection diagnosed during follow-up. Younger men also were more likely to not have a usual place for health care, not have visited a health care provider recently, and to have unmet health care needs. In multivariate analysis, age ≤30 years (hazard ratio (HR): 3.4; 95% CI: 1.4, 8.3) and unprotected receptive anal intercourse with HIV-positive or unknown status partners (HR: 4.1; 95% CI: 1.9, 9.1) were significantly associated with HIV acquisition. Conclusion In the largest cohort of prospectively-followed Black MSM in the US, HIV incidence was high, particularly among young men. Targeted, tailored and culturally appropriate HIV prevention strategies incorporating behavioral, social and biomedical based interventions are urgently needed to lower these rates.

Background American Black men who have sex with men (MSM) are disproportionately affected by HIV, but the factors associated with this concentrated epidemic are not fully understood. Methods Black MSM were enrolled in 6 US cities to evaluate a multi-component prevention intervention, with the current analysis focusing on the correlates of being newly diagnosed with HIV compared to being HIV-uninfected or previously diagnosed with HIV. Results HPTN 061 enrolled 1553 Black MSM whose median age was 40; 30% self-identified exclusively as gay or homosexual, 29% exclusively as bisexual, and 3% as transgender. About 1/6th (16.2%) were previously diagnosed with HIV (PD); of 1263 participants without a prior HIV diagnosis 7.6% were newly diagnosed (ND). Compared to PD, ND Black MSM were younger (p<0.001); less likely to be living with a primary partner (p<0.001); more likely to be diagnosed with syphilis (p<0.001), rectal gonorrhea (p = 0.011) or chlamydia (p = 0.020). Compared to HIV-uninfected Black MSM, ND were more likely to report unprotected receptive anal intercourse (URAI) with a male partner in the last 6 months (p<0.001); and to be diagnosed with syphilis (p<0.001), rectal gonorrhea (p = 0.004), and urethral (p = 0.025) or rectal chlamydia (p<0.001). They were less likely to report female (p = 0.002) or transgender partners (p = 0.018). Multivariate logistic regression analyses found that ND Black MSM were significantly more likely than HIV-uninfected peers to be unemployed; have STIs, and engage in URAI. Almost half the men in each group were poor, had depressive symptoms, and expressed internalized homophobia. Conclusions ND HIV-infected Black MSM were more likely to be unemployed, have bacterial STIs and engage in URAI than other Black MSM. Culturally-tailored programs that address economic disenfranchisement, increase engagement in care, screen for STIs, in conjunction with safer sex prevention interventions, may help to decrease further transmission in this heavily affected community.

HIV Prevention Research for African Americans: Current and Future Directions

Lula A. Beatty; Darrell P. Wheeler; Juarlyn L. Gaiter

African Americans experience HIV and AIDS at a rate 10 times greater than the U.S. White population. Although there have been advances in HIV risk-reduction strategies, these efforts have not been as successful in decreasing HIV infection in the African American population. This article reviews the research base of HIV prevention interventions to identify research that will lead to the development of more effective prevention strategies for African Americans. Major limitations found in the research include the exclusion of African Americans in studies, particularly those at higher risk, and the lack of using culturally based theory to guide research. Recommendations for improving research are offered. They include conducting research that focuses on structural interventions rather than individuals, controlling for diversity within the African American population, defining culture when using it in research, and developing a cadre of African American researchers involved in prevention intervention studies.

IMPORTANCE Emerging data warrant the integration of biomedical and behavioral recommendations for human immunodeficiency virus (HIV) prevention in clinical care settings. OBJECTIVE To provide current recommendations for the prevention of HIV infection in adults and adolescents for integration in clinical care settings. DATA SOURCES, STUDY SELECTION, AND DATA SYNTHESIS Data published or presented as abstracts at scientific conferences (past 17 years) were systematically searched and reviewed by the International Antiviral (formerly AIDS) Society-USA HIV Prevention Recommendations Panel. Panel members supplied additional relevant publications, reviewed available data, and formed recommendations by full-panel consensus. RESULTS Testing for HIV is recommended at least once for all adults and adolescents, with repeated testing for those at increased risk of acquiring HIV. Clinicians should be alert to the possibility of acute HIV infection and promptly pursue diagnostic testing if suspected. At diagnosis of HIV, all individuals should be linked to care for timely initiation of antiretroviral therapy (ART). Support for adherence and retention in care, individualized risk assessment and counseling, assistance with partner notification, and periodic screening for common sexually transmitted infections (STIs) is recommended for HIV-infected individuals as part of care. In HIV-uninfected patients, those persons at high risk of HIV infection should be prioritized for delivery of interventions such as preexposure prophylaxis and individualized counseling on risk reduction. Daily emtricitabine/tenofovir disoproxil fumarate is recommended as preexposure prophylaxis for persons at high risk for HIV based on background incidence or recent diagnosis of incident STIs, use of injection drugs or shared needles, or recent use of nonoccupational postexposure prophylaxis; ongoing use of preexposure prophylaxis should be guided by regular risk assessment. For persons who inject drugs, harm reduction services should be provided (needle and syringe exchange programs, supervised injection, and available medically assisted therapies, including opioid agonists and antagonists); low-threshold detoxification and drug cessation programs should be made available. Postexposure prophylaxis is recommended for all persons who have sustained a mucosal or parenteral exposure to HIV from a known infected source and should be initiated as soon as possible. CONCLUSIONS AND RELEVANCE Data support the integration of biomedical and behavioral approaches for prevention of HIV infection in clinical care settings. A concerted effort to implement combination strategies for HIV prevention is needed to realize the goal of an AIDS-free generation.

More than half a million Americans became newly infected with human immunodeficiency virus (HIV) in the first decade of the new millennium. The domestic epidemic has had the heaviest impact on men who have sex with men and persons from racial and ethnic minority populations, particularly black persons. For example, black men who have sex with men represent <1% of the US population but 25% of new HIV infections, according to Centers for Disease Control and Prevention estimates published in 2008. Although black and Hispanic women constitute 24% of all US women, they accounted for 82% of HIV infections among women in 2005, according to data from 33 states with confidential name-based reporting. There is a nearly 23-fold higher rate of AIDS diagnoses among black women (45.5 diagnoses per 100,000 women) and a nearly 6-fold higher rate among Hispanic women (11.2 diagnoses per 100,000 women), compared with the rate among white women (2.0 diagnoses per 100,000 women). Investigators from the HIV Prevention Trials Network, a National Institutes of Health-sponsored collaborative clinical trials group, have crafted a domestic research agenda with community input. Two new domestic studies are in progress (2009), and a community-based clinical trial feasibility effort is in development (2010 start date). These studies focus on outreach, testing, and treatment of infected persons as a backbone for prevention of HIV infection. Reaching persons not receiving health messages and services with novel approaches to both prevention and treatment is an essential priority for control of HIV infection in the United States; our research is designed to guide the best approaches and assess the impact of bridging treatment and prevention.

Overcoming biological, behavioral, and structural vulnerabilities: New directions in research to decrease HIV transmission in men who have sex with men

Abstract:Men who have sex with men (MSM), including transgender women, comprise a heterogeneous group of individuals whose sexual behaviors and gender identities may vary widely between cultures and among individuals. Their sources of increased vulnerability to HIV are diverse, including the increased efficiency of HIV transmission via unprotected anal intercourse, sexual role versatility, asymptomatic sexually transmitted infections, and behavioral factors that may be associated with condomless sex with multiple partners. Societal stigmatization of homosexual behavior and gender nonconformity may result in internalized negative feelings that lead to depression, other affective disorders, and substance use, which in turn are associated with increased risk-taking behaviors. Social stigma and punitive civil environments may lead to delays in seeking HIV and sexually transmitted disease screening, and later initiation of antiretroviral therapy. The iPrEX study demonstrated that chemoprophylaxis can decrease HIV acquisition in MSM, and the HIV prevention trials network 052 study established the biological plausibility that earlier initiation of highly active antiretroviral therapy can decrease HIV transmission to uninfected partners. Despite these advances, MSM remain among the most significantly HIV-affected population in resource-rich and limited settings. New studies will integrate enhanced understanding of the biology of enhanced rectal transmission of HIV and the focused use of antiretrovirals for prevention with culturally tailored approaches that address the potentiating social and behavioral factors associated with enhanced HIV spread among MSM.

LGBT Faculty, Research, and Researchers: Risks and Rewards

Michael C. LaSala; David A. Jenkins; Darrell P. Wheeler; Karen I. Fredriksen-Goldsen

ABSTRACT Self-identified lesbian, gay, bisexual, and transgender (LGBT) faculty along with heterosexuals with scholarly interests in these populations can face heterosexism, heterocentrism, homophobia, and hostility within and outside of social work programs. This article describes the risks and rewards of being an LGBT faculty based on the experiences of the authors. Myths and realities relating to coming out, promotion, and funding are discussed, along with the pitfalls of tokenism and the stress of being an LGBT faculty of color. Ways to endure and even thrive in spite of these potentially formidable burdens are also described.

Partners in Transition: The Transition Experience of Lesbian, Bisexual, and Queer Identified Partners of Transgender Men

Emily Joslin-Roher; Darrell P. Wheeler

While transgender individuals receive increasing attention in both academia and the social services, their partners remain a hidden population. This study was undertaken to examine the experiences of lesbian, bisexual, and queer identified partners of transgender men through the transition process. Nine subjects were interviewed. Major themes included the impact of transition on identity, community, caretaking, peer support, the relationship itself, and mental health. Isolation and lack of services were identified as significantly impacting the transition experiences of partners. Understanding the transition experience of partners has important implications for researchers and practitioners, and recommendations for further research and service improvement are provided.

Marzinke; William Clarke; Lei Wang; Vanessa Cummings; Ting Yuan Liu; Estelle Piwowar-Manning; Autumn Breaud; Sam Griffith; Susan Buchbinder; Steven Shoptaw; Carlos del Rio; Manya Magnus; Sharon Mannheimer; Sheldon D. Fields; Kenneth H. Mayer; Darrell P. Wheeler; Beryl A. Koblin; Susan H. Eshleman; Jessica M. Fogel

In The HIV Prevention Trials Network 061 study, 155 human immunodeficiency virus (HIV)-infected men reported no prior HIV diagnosis; 83 of those men had HIV RNA levels of <1000 copies/mL at enrollment. Antiretroviral drug testing revealed that 65 of the 83 (78.3%) men were on antiretroviral treatment. Antiretroviral drug testing can help distinguish between newly diagnosed and previously diagnosed HIV infection.

THE ROLE OF PEER SUPPORT ON CONDOM USE AMONG BLACk AND LATINO MSM IN THREE URBAN AREAS

Juli-Ann Carlos; Trista Bingham; Ann Stueve; Jennifer Lauby; George Ayala; Gregorio A. Millett; Darrell P. Wheeler

This article examines the sociodemographic/behavioral variables associated with low peer support of condom use and the relation between low peer support of condom use and unprotected anal sex for Black and Latino MSM in cities heavily impacted by the HIV/AIDS epidemic. Our findings indicate that perceived low peer support of condom use is associated with increased odds of recent unprotected anal intercourse (UAI) among Black and Latino MSM, regardless of male partner type. Although many participants reported having high peer support of condom use, this analysis highlights a considerable subgroup of Black and Latino MSM, 21% and 30%, respectively, who report low peer support of condoms. Given the prevalence of low peer support of condom use and its association with UAI in these highly impacted MSM populations, we recommend future intervention work that draws upon Black and Latino MSMs peer and social network members to reduce HIV risk behaviors.
