RESUMEN
In South Africa, HIV acquisition risk has been studied less in people assigned male at birth. We studied the associations between risk behaviors, clinical features and HIV incidence amongst males in two South African HIV preventive vaccine efficacy trials. We used Cox proportional hazards models to test for associations between demographics, sexual behaviors, clinical variables and HIV acquisition among males followed in the HVTN 503 (n = 219) and HVTN 702 (n = 1611) trials. Most males reported no male sexual partners (99.09% in HVTN 503) or identified as heterosexual (88.08% in HVTN 702). Annual HIV incidence was 1.39% in HVTN 503 (95% CI 0.76-2.32%) and 1.33% in HVTN 702 (95% CI 0.80-2.07%). Increased HIV acquisition was significantly associated with anal sex (HR 6.32, 95% CI 3.44-11.62), transactional sex (HR 3.42, 95% CI 1.80-6.50), and non-heterosexual identity (HR 16.23, 95%CI 8.13-32.41) in univariate analyses and non-heterosexual identity (HR 14.99, 95% CI 4.99-45.04; p < 0.01) in multivariate analysis. It is appropriate that prevention efforts in South Africa, although focused on the severe epidemic in young women, also encompass key male populations, including men who have sex with men, but also men who engage in anal or transactional sex.

BACKGROUND: The Human Immunodeficiency Virus (HIV) remains a global health burden, and despite the advancements in antiretroviral therapy and various strategies employed to curb HIV infections, the incidence of HIV remains disproportionately high among women. Therefore, this study aimed to determine the prevalence of the risk factors for the acquisition of HIV among sexually active women in Rwanda. METHODS: Secondary data from the 2020 Rwanda Demographic Health Survey, comprising 10,684 sexually active women, was used. Multistage stratified sampling was employed to select the study participants. Multivariable logistic regression was conducted to determine the associated risk factors using the SPSS (version 25). RESULTS: Of the 10,684 sexually active women, 28.7% (95% confidence interval (CI): 27.5-29.4) had at least one risk factor for HIV acquisition. Having no education (AOR = 3.65, 95%CI: 2.16-6.16), being unmarried (AOR = 4.50, 95%CI: 2.47-8.21), being from female-headed households (AOR = 1.75, 95%CI: 1.42-2.15), not having health insurance (AOR = 1.34, 95%CI: 1.09-1.65), no HIV test history (AOR = 1.44, 95%CI: 1.01-2.08), being from the poorest wealth quintile (AOR = 1.61, 95%CI: 1.14-2.27) and lack of exposure to mass media (AOR = 1.30, 95%CI: 1.07-1.58) were associated with higher odds of exposure to at least one HIV acquisition risk factor. In contrast, age groups of 25-34 (AOR = 0.56, 95%CI: 0.44-0.71) and 35-44 years (AOR = 0.62, 95%CI: 0.48-0.80), rural residence (AOR = 0.63, 95%CI: 0.49-0.81) and being from the western region (AOR = 0.67, 95%CI: 0.48-0.94) were associated with less odds of exposure to at least one HIV acquisition risk factor. CONCLUSION: More than a quarter of sexually active women in Rwanda had exposure to at least one risk factor for HIV acquisition. There is a need to maximize the use of mass media in disseminating HIV prevention and behavioral change messages. Engagement of religious leaders and promotion of HIV testing, especially among the never-testers, may be vital strategies in successful HIV prevention programs.

Men Who Have Sex with Men and Women (MSMW) experience discrimination from same-sex and heterosexual communities partially because of perceptions they feature high-risk sexual behavior, elevated polysubstance use levels, and constitute an HIV bridge population. We used a longitudinal multivariate generalized linear mixed model comparing sexual risk and substance use patterns for Men Who Have Sex with Men Only (MSMO) with MSMW in the same cohort study. Data consisted of 771 men reporting 3,705 sexual partnerships from 2012-2017. For high-risk sexual behavior multivariate results showed non-significant (p>0.05) differences for partner number and commercial sex work, and significantly less (p<0.05) HIV prevalence and condomless anal sex. However, MSMW had significantly higher levels of hallucinogen and prescription opioid use, and substance treatment histories. Only one HIV-positive MSMW had a transmittable viral load, negating the concept of an HIV bridge population. Results indicate the need for additional longitudinal studies comparing MSMO and MSMW.
RESUMEN
BACKGROUND: It is important to understand how HIV infection is transmitted in the population in order to guide prevention activities and properly allocate limited resources. In Ukraine and other countries where injecting drug use and homosexuality are stigmatized, the information about mode of transmission in case registration systems is often biased. METHODS: We conducted a cross-sectional survey in a random sample of patients registered at HIV clinics in seven regions of Ukraine in 2013-2015. The survey assessed behavioral risk factors and serological markers of viral hepatitis B and C. We analyzed the discrepancies between the registered mode of transmission and the survey data, and evaluated trends over 3 years. RESULTS: Of 2285 participants, 1032 (45.2%) were females. The proportion of new HIV cases likely caused by injecting drug use based on the survey data was 59.7% compared to 33.2% in official reporting, and proportion of cases likely acquired through homosexual transmission was 3.8% compared to 2.8%. We found a significant decrease from 63.2 to 57.5% in the proportion of injecting drug use-related cases and a steep increase from 2.5 to 5.2% in homosexual transmission over 3 years. CONCLUSIONS: The study confirmed the significant degree of misclassification of HIV mode of transmission among registered cases. The role of injecting drug use in HIV transmission is gradually decreasing, but remains high. The proportion of cases related to homosexual transmission is relatively modest, but is rapidly increasing, especially in younger men. Improvements in ascertaining the risk factor information are essential to monitor the epidemic and to guide programmatic response.

BACKGROUND: A low prevalence of HIV in sickle cell disease (SCD) patients has been reported in the literature though mechanisms for this are not understood. METHODS: HIV risk behaviors were compared between SCD cases and non-SCD controls using a self-administered audio computer-assisted self-interview. SCD cases were recruited from a multi-center SCD cohort established in Brazil; controls were recruited from SCD social contacts. Categorical variables were analyzed using Chi-Square or Fisher exact test. Continuous variables were compared using the Mann-Whitney U test. RESULTS: There were 152 SCD cases and 154 age/location matched controls enrolled at three participating Brazilian centers during 2016-17. No significant differences in number of sexual partners (lifetime or previous 12 months), male-to-male sex partners or intravenous drug use were observed. Cases received more transfusions, surgeries, and acupuncture treatment. CONCLUSIONS: Besides the risk of transfusion-transmitted HIV, which is now exceedingly rare, SCD and non-SCD participants demonstrated similar HIV risk behaviors. Causes other than risk behaviors such as factors inherent to SCD pathophysiology may explain the reported low prevalence of HIV in SCD.

Reducing multiple and concurrent partnerships has been identified as a priority in generalised HIV epidemics, yet developing successful interventions to bring about such behaviour change has proven challenging. We offered a three-session intervention aimed to improve couple relationship quality and address HIV risk factors, particularly concurrent sexual partnerships (CSP), in a peri-urban community of Kampala, Uganda. Before launching the intervention, a different group of community members participated in eight single-gender focus group discussions (FGDs) which explored issues of couple relationship quality and satisfaction. Findings from the FGDs guided the intervention. All 162 couples invited to the intervention completed a survey pre- and post-intervention. In FGDs, women and men discussed challenges faced in their relationships, including pervasive dissatisfaction, financial constraints, deception and lack of trust, poor communication, lack of sexual satisfaction, and concurrent sexual partnerships. A difference-in-difference analysis showed no measurable impact of the intervention on relationship quality or sexual risk behaviours over a six-month follow-up among 183 individuals who participated in the intervention, although many stated in response to open-ended questions that they had experienced positive relationship changes. Qualitative findings suggest high demand for couple-focused interventions but also reveal many individual-, couple-, community- and structural-level factors which contribute to women and men seeking concurrent sexual partnerships. More intensive interventions may be needed to overcome these barriers to behaviour change and reduce HIV risk. These findings also raise questions about how to interpret divergent qualitative and quantitative data, a topic which has received little attention in the literature.

BACKGROUND: Schistosoma mansoni infection has been associated with increased risk of HIV transmission in African women. This association might be causal or mediated through shared socio-behavioural factors and associated co-infections. We tested the latter hypothesis in a cross-sectional pilot study in a cohort of women from a S. mansoni endemic region of Uganda. To validate the immunological effects of S. mansoni in this cohort, we additionally assessed known schistosomiasis biomarkers. METHODS: HIV-uninfected non-pregnant adult women using public health services were tested for schistosomiasis using the urine circulating cathodic antigen test, followed by serology and Schistosoma spp.-specific PCR. Blood was obtained for herpes simplex virus (HSV)-2 serology, eosinophil counts and cytokine analysis. Samples collected from the genitourinary tract were used to test for classical sexually transmitted infections (STI), for bacterial vaginosis and to assess recent sexual activity via prostate-specific antigen testing. Questionnaires were used to capture a range of socio-economic and behavioral characteristics. RESULTS: Among 58 participants, 33 (57%) had schistosomiasis, which was associated with elevated levels of interleukin (IL)-10 (0.32 vs. 0.19 pg/ml; p = 0.038) and a trend toward increased tumour necrosis factor (TNF) (1.73 vs. 1.42 pg/ml; p = 0.081). Eosinophil counts correlated with levels of both cytokines (r = 0.53, p = 0.001 and r = 0.38, p = 0.019, for IL-10 and TNF, respectively); the association of eosinophilia with schistosomiasis was not significant (OR = 2.538, p = 0.282). Further, schistosomiasis was associated with lower age (per-year OR = 0.910, p = 0.047), being unmarried (OR = 0.263, p = 0.030), less frequent hormonal contraceptive (HC) use (OR = 0.121, p = 0.002, dominated by long acting injectable contraceptives) and a trend to longer time since penile-vaginal sex (OR = 0.350, p = 0.064). All women infected by Chlamydia trachomatis (n = 5), were also positive for schistosomiasis (Fisher's exact p = 0.064). CONCLUSIONS: Intestinal schistosomiasis in adult women was associated with systemic immune alterations, suggesting that associations with immunological correlates of HIV susceptibility warrant further investigation. S. mansoni associations with socio-behavioral parameters and C. trachomatis, which may alter both genital immunity and HIV exposure and/or acquisition risk, means that future studies should carefully control for potential confounders. These findings have implications for the design and interpretation of clinical studies on the effects of schistosomiasis on HIV acquisition.

Violence Against Children and Youth Survey (VACS) data from seven countries were analyzed to estimate population-level eligibility for the President's Emergency Plan for AIDS Relief (PEPFAR) Determined, Resilient, Empowered, AIDS-Free, Mentored, and Safe (DREAMS) HIV prevention program for adolescent girls and young women (AGYW). The prevalence of overall eligibility and individual risk factors, including experiences of violence, social, and behavioral risks differ across countries and age groups. A large proportion of AGYW across all countries and age groups examined have at least one risk factor making them eligible for DREAMS. Experiencing multiple risks is also common, suggesting that researchers and programs could work together to identify combinations of risk factors that put AGYW at greatest risk of HIV acquisition, or that explain most new HIV infections, to more precisely target the most vulnerable AGYW. The VACS provides important data for such analyses to refine DREAMS and other youth programming.

BACKGROUND: The menstrual cycle influences HIV infection-risk in women, although the timing and underlying mechanism are unclear. Here we investigated the contribution of the menstrual cycle to HIV susceptibility through evaluating immune behavior with infection-risk over time. METHODS: Blood and vaginal lavage samples were collected from 18 pig-tailed macaques to evaluate immune changes over reproductive cycles, and from 5 additional animals undergoing repeated vaginal exposures to simian HIV (SHIV). Peripheral blood mononuclear cell (PBMC) samples from healthy women (n = 10) were prospectively collected over the course of a menstrual cycle to profile T cell populations. Immune properties from PBMC and vaginal lavage samples were measured by flow cytometry. Plasma progesterone was measured by enzyme immunoassay. The oscillation frequency of progesterone concentration and CCR5 expression on CD4 T cells was calculated using the Lomb-Scargle periodogram. SHIV infection was monitored in plasma by RT-PCR. Immune measures were compared using generalized estimating equations (GEE). FINDINGS: Macaques cycle-phases were associated with fluctuations in systemic immune properties and a type-1 inflammatory T cell response with corresponding CCR5+ memory CD4 T cell (HIV target cell) infiltration into the vaginal lumen at the late luteal phase. Power spectral analysis identified CCR5 oscillation frequencies synchronized with reproductive cycles. In a repetitive low-dose vaginal challenge model, productive SHIV163P3 infection only occurred during intervals of mounting type-1 T cell responses (n = 5/5). Finally, we identify similar type-1 inflammatory T cell responses over the menstrual cycle are occurring in healthy women. INTERPRETATION: These data demonstrate that periodic shifts in the immune landscape under menstrual cycle regulation drives bystander CCR5+ CD4 T cell recruitment and HIV susceptibility in the female reproductive tract. FUNDING: This study was supported by the U.S. Centers for Disease Control and Prevention, Atlanta, GA 30329 and NIH grants to Emory University (K23AI114407 to A.N.S., the Emory University Center for AIDS research [P30AI050409], and Atlanta Clinical and Translational Sciences Institute [KLR2TR000455, UL1TR000454]).

BACKGROUND OR OBJECTIVES: Worldwide, men who have sex with men (MSM) and Transgender persons are vulnerable to psychosocial factors associated with high risk for HIV, and suffer disproportionately high rates of HIV/AIDS. In the United States (US), the House Ball Community (HBC) is a social network comprised predominantly of Black and Hispanic MSM and Transgender persons who reside in communal settings. This study explores Western New York HBC leaders' perceptions of HIV in their communities and their knowledge of HIV prevention strategies, including HIV vaccine trials. METHODS: The project was conducted using an exploratory approach based on the principles of Community-Based Participatory Research (CBPR) methods. An HIV behavioral risk assessment provided descriptive data, while qualitative measures explored psychosocial and behavioral factors. RESULTS: Behavioral assessments indicated high levels of risky sexual behaviors and experiences of violence. Interviews with 14 HBC leaders revealed that knowledge of HIV and local HIV vaccines trials was limited. Barriers to HIV knowledge included fear of peer judgment, having inaccurate information, and lack of formal education. Experiencing violence was identified as barrier to positive health behavior. Nevertheless, the HBC was described as a safe and creative space for marginalized MSM and Transgender youth. CONCLUSION AND GLOBAL HEALTH IMPLICATIONS: Findings suggest that the interrelation between health problems and social context amplify HIV risk in the HBC. The organizational structure and resources of the HBC, and MSM/Transgender communities worldwide can be instrumental in informing interventions to address HIV-related risk behaviors and create appropriate recruitment tools to ensure their representation in HIV research.
RESUMEN
Human immunodeficiency virus (HIV) remains a leading cause of global morbidity with the highest burden in Sub-Saharan Africa (SSA). For reasons that are incompletely understood, the likelihood of HIV transmission is several fold higher in SSA than in higher income countries, and most of these infections are acquired by young women. Residents of SSA are also exposed to a variety of endemic infections, such as malaria and various helminthiases that could influence mucosal and systemic immunology. Since these immune parameters are important determinants of HIV acquisition and progression, this review explores the possible effects of endemic infections on HIV susceptibility and summarizes current knowledge of the epidemiology and underlying immunological mechanisms by which endemic infections could impact HIV acquisition. A better understanding of the interaction between endemic infections and HIV may enhance HIV prevention programs in SSA.
RESUMEN
BACKGROUND: Using data from HIV Prevention Trials Network 064, a multisite, observational cohort study conducted to estimate HIV incidence rates among women living in areas of high poverty and HIV prevalence in the United States, we examined the use of HIV risk characteristics to predict emotional abuse, physical violence, and forced sex. METHODS: Participants included 2099 women, 18-44 years of age, who reported unprotected vaginal or anal sex with a male partner and an additional personal or perceived male partner HIV risk characteristic in the past 6 months. Adjusting for time-varying covariates, generalized estimating equations were used to assess the ability of HIV risk characteristics to predict violence 6 months later. RESULTS: Reported analyses were limited to the 1980 study participants who reported having a male sex partner at that assessment. Exchanging sex, perceived partner concurrency, and perceived partner incarceration were significantly predictive of emotional abuse 6 months later (adjusted odds ratio [AOR]: 1.60; 1.59; 1.34, respectively). Prior sexually transmitted infection diagnosis, exchanging sex, and binge drinking were significantly predictive of physical violence 6 months later (AOR: 1.62; 1.71; 1.47, respectively). None of the variables measured was significantly predictive of forced sex. CONCLUSIONS: Strategies that address reducing violence against women should be studied further in the context of HIV prevention programs.

The prevalence of HIV is substantially higher among prisoners than the general population, while the incidence varies considerably in different regions around the world. If we consider Sub-Saharan Africa as one region with the highest prevalence of HIV, data on African prisoners would be limited. Despite the low prevalence of HIV in the Middle East and North Africa, its incidence is rising in these regions with a few exceptions; there are insufficient data on HIV prevalence in prisons. A similar situation is present in both Pacific and Central Asia as well as in Eastern Europe. A high rate of infection is mainly observed among prisoners in Western and Central parts of Europe, since the data from these are more available than other parts. Nowadays, the sexual transmission mode and tattooing are important ways in HIV risks among prisoners after injecting drug use as the most common route of HIV transmission in all regions. However, it is difficult to compare and analyze the prevalence of HIV among prisoners in different regions regarding the limited data and different methods which they used in collecting data. Eventually, it can certainly be said that prisons are one of the high-risk places for HIV transmission; on the other hand, can be a suitable place for implementing HIV case-finding, linkage to treatment and harm reduction programs.
RESUMEN
OBJECTIVE: To conduct statistical analysis to assess the association between alcohol use and HIV status using Demographic Health Survey data from Zambia (2013-2014) and Zimbabwe (2015-2016). RESULTS: The study showed an association between alcohol use and HIV status using nationally representative population-based surveys. The surveys were conducted among men (15-54 years) and women (15-49 years) in 2013-2014 and 2015-2016 in Zambia and Zimbabwe respectively. HIV prevalence in the two countries was higher among males and females who drank alcohol compared to those who did not. This study reinforces the existing knowledge base on the association between alcohol use and HIV sero-status and calls for further research to explore the causal pathways between alcohol consumption and HIV status.

PURPOSE: The purpose of this study was to determine whether there is adherence to the October 2011 American Academy of Pediatrics (AAP) recommendations for HIV screening in a large urban adolescent program with availability of a publicly funded program providing free, confidential, sexually transmitted infection (STI) and HIV counseling and testing (then rapid or third generation HIV testing), nested in the same adolescent clinic. METHODS: We conducted a retrospective chart review of HIV screening trends among 13- to 24-year-old patients tested for HIV during periods of January 2010 to June 2011 (18 months pre-AAP recommendations period) and July 2011 to December 2012 (18-month period, which included 15 months after the AAP recommendations). RESULTS: During the period of January 2010 to June 2011, there were 22 tests/1,000 medical visits (N = 824 of 37,520 medical visits), and during the period of July 2011 to December 2012, there were 27 tests/1,000 medical visits (N = 1,068 of 38,763 medical visits) (p < 0.0001, odds ratio [OR] 1.26). The number of 13- to 18-year-old patients screened in the pre-AAP period was 150, compared to 297 in the second 18-month period (X 2 = 43.3, df = 1, p < 0.0001). A summative risk profile score of 0-9 was created in the form of a continuous variable, with a risk score of 0 for those with no risk factor identified and 1 point for each risk behavior identified. The proportion of HIV test clients with zero-specified risk (a risk score of "0") increased from 2010 to 2012. CONCLUSION: Release of the 2011 AAP HIV testing guidelines was associated with a modest increase in HIV screening and a shift toward testing younger people and away from risk-based screening.
RESUMEN
Introduction: The presence of metabolic syndrome and cardiovascular risk in HIV positive patients has been overlooked in patients with HIV infection. Objectives: To evaluate the frequency of metabolic syndrome and compare cardiovascular risk stratification according to the Framingham, PROCAM, and SCORE equations in HIV patients. Methodology: A cross-sectional study of 760 HIV-infected adults from January 2016 to December 2018. The presence of metabolic syndrome was assessed using the ATP-III criteria, and the cardiovascular risk score was examined. Results: The most frequent comorbidities were smoking, hypercholesterolemia, and high blood pressure. Student's T test was carried out, showing differences in the classification of low to moderate risk. The number of HIV-infected male patients identified as having moderate cardiovascular risk according to the Framingham risk equation was two folds compared to those with the PROCAM and SCORE systems. Conclusions: This study showed a high prevalence of patients with low cardiovascular risk. It is appropriate to consider cardiovascular risk factors in patients with HIV, since they are very frequently associated with adverse outcomes of this type.
Introducción: La presencia del síndrome metabólico y el riesgo cardiovascular en pacientes VIH positivos ha sido desestimado en pacientes con infección por VIH. Objetivos: Evaluar la frecuencia del síndrome metabólico y comparar la estratificación del riesgo cardiovascular según las ecuaciones de Framingham, PROCAM y SCORE en pacientes con VIH. Metodología: estudio transversal de 760 adultos infectados por el VIH en el periodo enero de 2016-diciembre de 2018. Se evaluó la presencia de síndrome metabólico a través de los criterios del ATP-III y se examinó la puntuación de riesgo cardiovascular. Resultados: Las comorbilidades más frecuentes fueron el tabaquismo, la hipercolesterolemia y la hipertensión arterial. Se realizó la prueba T de Student, y a partir de ella se lograron apreciar diferencias en categorización de riesgo bajo a moderado. El número de pacientes varones infectados por el VIH identificados como de riesgo cardiovascular moderado según la ecuación de riesgo de Framingham fue mayor del doble en comparación con los sistemas PROCAM y SCORE. Conclusiones: El estudio mostró una alta prevalencia de pacientes con bajo riesgo cardiovascular. Es pertinente considerar los factores de riesgo cardiovascular en pacientes con VIH, ya que estos se encuentran frecuentemente asociados con desenlaces adversos de este tipo.

BACKGROUND: Sub-Saharan African Migrants (SAM) are the second largest group affected by HIV/AIDS in Belgium and the rest of Western Europe. Increasing evidence shows that, more than previously thought, SAM are acquiring HIV in their host countries. This calls for a renewed focus on primary prevention. Yet, knowledge on the magnitude of the HIV epidemic among SAM (HIV prevalence estimates and proportions of undiagnosed HIV infections) and underlying drivers are scarce and limit the development of such interventions. OBJECTIVE: By applying a community-based participatory and mixed-methods approach, the TOGETHER project aims to deepen our understanding of HIV transmission dynamics, as well as inform future primary prevention interventions for this target group. METHODS: The TOGETHER project consists of a cross-sectional study to assess HIV prevalence and risk factors among SAM visiting community settings in Antwerp city, Belgium, and links an anonymous electronic self-reported questionnaire to oral fluid samples. Three formative studies informed this method: (1) a social mapping of community settings using an adaptation of the PLACE method; (2) a multiple case study aiming to identify factors that increase risk and vulnerability for HIV infection by triangulating data from life history interviews, lifelines, and patient files; and (3) an acceptability and feasibility study of oral fluid sampling in community settings using participant observations. RESULTS: Results have been obtained from 4 interlinked studies and will be described in future research. CONCLUSIONS: Combining empirically tested and innovative epidemiological and social science methods, this project provides the first HIV prevalence estimates for a representative sample of SAM residing in a West European city. By triangulating qualitative and quantitative insights, the project will generate an in-depth understanding of the factors that increase risk and vulnerability for HIV infection among SAM. Based on this knowledge, the project will identify priority subgroups within SAM communities and places for HIV prevention. Adopting a community-based participatory approach throughout the full research process should increase community ownership, investment, and mobilization for HIV prevention.
RESUMEN
The purpose of this manuscript is to assess and compare HIV risk behaviors among early adolescents after a three-year pilot study. A total of 135 public and private junior high schools students completed the intervention protocol. A self-administered questionnaire was given at baseline and at the end of the third year (fourth measure). Descriptive and inferential analyses were performed using SPSS 20.0. About 60% of the students were 14 years old at the fourth measure. The proportion of students that did not report at least one HIV risk behavior at baseline and those that reported any risk behavior at the fourth measure was lower in the intervention group (45.0%) than in the control group (54.5%). The proportion of students that reported at least one HIV risk behavior at baseline and those that did not report any HIV risk behavior at the fourth measure was higher in the intervention group than in the control group (33.3% vs. 8.3%). The proportion of students engaging in HIV risk behaviors was higher in the control group than in the intervention group at the fourth measure, suggesting that A Supportive Model for HIV Risk Reduction in Early Adolescence (ASUMA) intervention might be a promising initiative to reduce adolescents' engagement in HIV risk behaviors.
