Prevent HIV Transmission Research Articles

A qualitative study to explore daily versus on-demand oral pre-exposure prophylaxis (PrEP) in young people from South Africa, Uganda and Zimbabwe.

Adolescents in sub-Saharan Africa (SSA) remain vulnerable to HIV infection. While pre-exposure prophylaxis (PrEP) is highly effective in preventing HIV transmission as a daily or on-demand regimen, tailored approaches are necessary. The Combined HIV Adolescent PrEP and Prevention Study (CHAPS) is a mixed-methods research program investigating the acceptability and feasibility of implementing daily and on-demand PrEP among young people in SSA. It also aims to determine an on-demand dosing schedule for insertive sex. For this paper, we explored preferences for daily versus on-demand PrEP amongst adolescents as part of CHAPS. Purposive sampling was used to recruit participants from Soweto and Cape Town (South Africa), Wakiso district (Uganda) and Chitungwiza (Zimbabwe). At the time of the study in 2018/2019, Uganda had not rolled out PrEP to the general population; in Zimbabwe, PrEP for young people was only available at selected sites with one located within the study recruitment area. In South Africa, PrEP was made available to selected high-risk groups. We conducted 60 in-depth interviews and 24 group discussions amongst young people aged 13-24 without HIV in South Africa, Uganda, and Zimbabwe. All in-depth interviews and group discussions were audio-recorded, transcribed verbatim and translated to English. Data were analysed using framework analysis. The main themes were centered around preferences for daily and on-demand PrEP. Reasons for on-demand preferences included stigma, pill fatigue, adherence and side effects. Reasons for daily PrEP preferences included factors related to sexual risk behaviour, continuous protection against incidents of unintentional exposure, and the increased efficacy of a daily dose. Participants at all sites preferring daily PrEP identified the same reasons, with more males than females citing inadvertent blood contact or perceived increased efficacy. Similarly, participants at all sites preferring on-demand PrEP gave the same reasons for their preferences for on-demand PrEP; the exception was South Africans who did not mention the hope of having fewer side effects by not taking daily PrEP. Additionally, more males than females cited intermittent sex as a reason for opting for on-demand PrEP. Our study is the first known to explore and describe youth preferences for daily versus on-demand PrEP. While the choice is clear-cut, the reasons cited in the different options provide invaluable insights into their decisions, and the actual and perceived facilitators and barriers to access to PrEP. Further education is needed amongst young people, not only about PrEP but also in other areas of comprehensive sexuality education. Exploring all options of HIV prevention is crucial to provide a tailored, one-size-does-not-fit-all approach to adolescent care in SSA to reduce and, the continued and increasing risk of this preventable infection.

ANALYSIS OF HIV AND SYPHILIS TRANSMISSION PREVENTION PROGRAMS FOR ADOLESCENTS

Background: Adolescents tend to want to try things they have never experienced, and the main contributing factor is curiosity and imitating what adults do, including sexuality. Aims: This study aimed to analyze the transmission prevention program of HIV and Syphilis for adolescents in North Sumatra. Methods: This study used an analytic survey approach with a cross-sectional design by taking 729 people as a sample, selected using quota sampling, from the total adolescent population (19.4% of the population of North Sumatra). Questionnaires produced using an online platform and adapted from The Prospero Network. The results were then transferred into a statistics-based application for descriptive data analysis, bivariate, and multi-level tests. Results: The study showed that >50% of the respondents took a quick, free laboratory test for HIV and syphilis and a reactive confirmation test through a health facility in both cases. Moreover, the results of multi-level statistical tests show models 1 and 2, namely the availability of syphilis screening referrals, have a 1-17 times higher risk of implementing HIV and syphilis programs in adolescents. Conclusion: Everything is interrelated with the implementation of HIV and Syphilis transmission prevention programs in adolescents. However, there is still a significant chance that it will not work. Therefore, the government and the community must work together to implement this program properly and consistently. Keywords: Adolescents, Health Program, HIV, Syphilis

Analysis of online user discussions on Reddit associated with the transition of use between HIV PrEP therapy.

In 2019, the U.S. Food and Drug Administration (FDA) approved emtricitabine and tenofovir alafenamide (Descovy) as another option for HIV pre-exposure prophylaxis (PrEP) prevention for high-risk adults and adolescents. With the introduction of this new PrEP, millions of current users on emtricitabine and tenofovir disoproxil fumarate (Truvada), another PrEP medication currently used to prevent HIV transmission, have options of whether to continue their current treatment regime or transition to new treatment options. The objective of this study was to conduct a descriptive analysis to characterize user-generated social media conversations on Reddit associated with FDA-approved PrEP prevention treatment options. Key themes identified were associated with perceptions, knowledge, and attitudes associated with the transition of use of different PrEP medications. Data were collected retrospectively and prospectively from the Reddit platform for posts with keywords filtered for HIV, PrEP, and FDA-approved PrEP prevention treatment from October 2020 to December 2020. We chose the Reddit platform based on prior studies that have identified PrEP user conversations and insights on access challenges for specific AIDS communities, such as gays and men who have sex with men (MSM). Reddit posts were then manually annotated using an inductive content coding approach for key themes regarding the transition of use and other emergent themes from user-generated content. Formal coding of text data was conducted with refined codes, and sub-codes created. A total of 3,120 posts were analyzed from Reddit resulting in 315 posts that were coded for PrEP and 105 posts (33.33%) specific to user discussions regarding the transition of PrEP prevention. Overall, users expressed interest in drug switching to Descovy, particularly in the context of poorer adherence or concerns about existing side effects associated with Truvada. Other major themes included discussions about the cost of Descovy, apprehension about side effects in comparison to Truvada, insurance coverage changes, and discussions about the donation of Truvada to other users after transitioning. Among these discussions, topics related to sexual minorities, including MSM, reported concerns when considering a switch in their HIV prevention regime. Understanding the changing public perception associated with the introduction of new HIV prevention is important in the context of market access, patient safety, pharmacovigilance, and health equity, particularly among high-risk populations such as MSM. Results support the use of social media from a digital pharmacovigilance perspective to better understand emerging HIV prevention, treatment, and adherence challenges experienced by patients.

Community-based HIV prevention services for transgender people in Ukraine: current situation and potential for improvement

BackgroundCommunity-based HIV-prevention services are a key approach to prevent HIV transmission among key population representatives. Transgender people have multiple specific needs and it is crucial to use prevention approaches that effectively respond to those needs and facilitate barriers on the way to use HIV prevention and related services. This study is aimed to explore the current state of community-based HIV prevention services among transgender people in Ukraine, its limitations and potential for improvement based on the experience and perceptions of transgender people, physicians, and community social workers providing services to transgender people.MethodsSemi-structured in-depth interviews were conducted among physicians providing services to transgender people (N = 10), community social workers (N = 6), and transgender people (N = 30). The objectives of the interviews were to explore: the relevance of the community-based HIV prevention services to the needs of transgender people; the key components of the most preferred (“ideal”) HIV-prevention package for transgender people; ways to optimize the existing HIV prevention package for transgender people including enrollment and retention. Systematically collected data were analyzed and coded into the main domains, thematic categories and subcategories using thematic analysis.ResultsThe current HIV prevention programs were well-evaluated by the majority of respondents. Gender-affirming care was found to be the key need of transgender people. Integration of HIV prevention services and gender-affirming care was perceived as the main way to address the needs of transgender people. Internet-based and peer word-of-mouth recruitment may improve enrollment in services. Optimization of existing HIV prevention package may include: psychological counseling, referral and navigation to medical services, legal services, pre- and post-exposure prevention, dissemination of tube lubricants, femidoms and latex wipes, use of oral fluid test systems for HIV self-testing.ConclusionsThe findings of this study suggest potential solutions to improve community-based HIV prevention services for transgender people by introducing a transgender people -oriented package, which integrates gender transition, HIV prevention and other services. Provision of prevention services based on assessed risk and referral/navigation to related services are the key options for optimization of the existing HIV prevention package.Trial registrationNot applicable.

EFdA efficiently suppresses HIV replication in the male genital tract and prevents penile HIV acquisition.

Sexually transmitted HIV infections in heterosexual men are acquired through the penis. Low adherence to condom usage and the fact that 40% of circumcised men are not protected indicate the need for additional prevention strategies. Here, we describe a new approach to evaluate the prevention of penile HIV transmission. We demonstrated that the entire male genital tract (MGT) of bone marrow/liver/thymus (BLT) humanized mice is repopulated with human T and myeloid cells. The majority of the human T cells in the MGT express CD4 and CCR5. Direct penile exposure to HIV leads to systemic infection including all tissues of the MGT. HIV replication throughout the MGT was reduced 100-1,000-fold by treatment with 4'-ethynyl-2-fluoro-2'-deoxyadenosine (EFdA), resulting in the restoration of CD4+ T cell levels. Importantly, systemic preexposure prophylaxis with EFdA effectively protects from penile HIV acquisition. IMPORTANCE Over 84.2 million people have been infected by the human immunodeficiency virus type 1 (HIV-1) during the past 40 years, most through sexual transmission. Men comprise approximately half of the HIV-infected population worldwide. Sexually transmitted HIV infections in exclusively heterosexual men are acquired through the penis. However, direct evaluation of HIV infection throughout the human male genital tract (MGT) is not possible. Here, we developed a new in vivo model that permits, for the first time, the detail analysis of HIV infection. Using BLT humanized mice, we showed that productive HIV infection occurs throughout the entire MGT and induces a dramatic reduction in human CD4 T cells compromising immune responses in this organ. Antiretroviral treatment with novel drug EFdA suppresses HIV replication in all tissues of the MGT, restores normal levels of CD4 T cells and is highly efficient at preventing penile transmission.

Pengalaman Tenaga Kesehatan dalam Melakukan Tes HIV pada Ibu Hamil di Puskesmas

The number of new HIV cases in DKI Jakarta is increasing every year. The East Jakarta has the highest incidence of HIV cases. The increasing number of HIV cases is not followed by awareness of HIV test, especially pregnant women. The purpose of this study was to obtain an overview of the experience of health care providers in performing HIV tests on pregnant women. The research method was descriptive narrative with participants from health workers who did HIV tests on pregnant women. The research was conducted at two Community Health Center in East Jakarta. Interviews used structured questions, conducted for 30 – 55 minutes, and recorded using a digital voice recorder with 13 participants. The data were analyzed using content analysis techniques. The four themes emerged including HIV test was mandatory for pregnant women at the first visit (K1); emphasizing on explaining the benefits of HIV test for prevention of HIV transmission in children; coordinating in the implementation HIV test for pregnant women and handling of those who are HIV positive; and challenges in implementing HIV test. in pregnant women. Health education about the importance of HIV test for pregnant women should be done from an early age. Additional of reagents HIV test for mothers from other regions is needed. The results of this study are expected to be input in improving the quality of HIV test for pregnant women.

Pre-exposure prophylaxis uptake for high-risk men who have sex with men in China: a multi-city cross-sectional survey

BackgroundPre-exposure prophylaxis (PrEP) is a proven biomedical strategy to prevent HIV transmission among men who have sex with men (MSM). Despite oral PrEP is safe and effective in MSM, the use of PrEP has been discouraging, especially in high-risk MSM. And there are no relevant studies showing the use of PrEP in high-risk MSM. The purpose of this study was to get the rate of PrEP use and the factors influencing PrEP use among high-risk MSM.MethodsA cross-sectional study was conducted through an electronic questionnaire on the “i guardian Platform”, and “snowballing” method was used to recruit MSM in six cities in China, including Beijing, Shenzhen, Chengdu, Changsha, Jinan and Nanjing in China, from January to April 2021. Univariate and multivariate logistic regression analysis were used to analyze the factors associated with the use of PrEP among high-risk MSM who had heard about PrEP.ResultsAmong the 1865 high-risk MSM who had heard of PrEP, the rates of those who were willing to use PrEP, had knowledge awareness of PrEP, and had used PrEP were 96.7%, 24.7%, and 22.4%, respectively. Multivariate logistic regression analysis of PrEP use in high-risk MSM showed that more PrEP was used by those who were 26 years or older (OR = 1.86, 95%CI 1.17 ~ 2.99), had master degree or above (OR = 2.37, 95% CI 1.21 ~ 4.72), had unstable work (OR = 1.86, 95% CI 1.16 ~ 2.96), had tested five or more HIV times in the past year (OR = 3.09, 95% CI 1.65 ~ 6.04), had consulted PrEP (OR = 22.05, 95% CI 14.87 ~ 33.91) and had PrEP knowledge awareness (OR = 1.90, 95% CI 1.41 ~ 2.55) (P < 0.05).ConclusionsThe rate of PrEP use in high-risk MSM was relatively low. PrEP was used more by high-risk MSM with unstable jobs, higher education, frequent HIV testing, and PrEP counseling. Public education on PrEP for MSM should continue to be enhanced to help them use PrEP in a timely and accurate manner.

Incidence and Predictors of Loss to Follow-Up Among Adults on Antiretroviral Therapy in South Gondar Governmental Hospitals, Ethiopia: Retrospective Cohort Study.

Approximately 38.4 million adult people worldwide live with HIV, of which the majority live in Africa. In Ethiopia increasing the quality of life to HIV patients and preventing HIV transmission are challenging. Even though test-and-treat strategy is applied for early enrollment to ART, poor retention and loss to follow-up are hindering the care. This study examined the incidence and predictors of loss to follow-up among adult HIV patients on ART in South Gondar governmental hospitals, September 11, 2017-September 10, 2022. A multi-facility-based retrospective follow-up study was conducted. Study subjects were assigned using simple random sampling methods by their medical record numbers. The data were entered into EPI data version 3.0.2 and exported to STATA version 17 for analysis. The Kaplan-Meier failure function was employed to determine the overall failure estimates. Cox proportional hazard model was tailored for both bi-variable and multivariable. Variables at p-value <0.05 with 95% CI were significantly associated with loss to follow-up. In this study, about 559 adult HIV survivors were included, and the response rate was 98%. The mean age and standard deviation (±SD) of study subjects were 36.6±9.3 years. The incidence rate of loss to follow-up was 6.7 per 100 person-years (95% CI: 5.6, 8.1). Educational status [AHR: 1.68 (95% CI: 1.04, 2.72)], substance use [AHR: 2.38 (95% CI: 1.50, 3.75)], and ART adherence [AHR: 3.33 (95% CI: 1.38, 8.08)] were significant determinants to loss to follow-up. In conclusion, the study finding reported that the incidence of loss to follow-up was low. HIV patients who did not have formal education, substance users, and poor ART adherence were at greater hazard of being lost to follow-up. In order to mitigate the rate of loss to follow-up, it is recommended to strengthen the available intervention modalities.

CO104 Trajectories of Adherence to Pre-Exposure Prophylaxis (PrEP) and Risk of HIV Incidence

Pre-exposure prophylaxis (PrEP) is effective in preventing HIV transmission and acquisition. However, poor adherence may limit its efficacy. Thus, we examined the association between adherence trajectories of PrEP and the risk of HIV acquisition among PrEP users.

The Vital Role of Public Health Nurses in Perinatal HIV Prevention and Elimination.

Perinatal HIV transmission remains a significant public health challenge, with an estimated 160,000 children newly infected with HIV each year. Public health nurses play a critical role in the prevention and elimination of perinatal HIV transmission through targeted interventions such as identification of pregnant women with HIV, referral and linkage to care, provision of antiretroviral therapy, and follow-up and retention in care for both mothers and infants. However, significant barriers to successful implementation exist, including stigma and discrimination, limited access to healthcare services, socioeconomic factors, and limited resources. Addressing these barriers will require a multifaceted approach that includes policy changes, community engagement, and targeted support and resources for affected families. In this review article, we provide an overview of the epidemiology of perinatal HIV transmission, current strategies for prevention and elimination, and the vital role of public health nurses in these efforts. We will also discuss the barriers to the successful implementation of public health nurse interventions and the future directions for research and practice in this field. Ultimately, the goal of perinatal HIV prevention and elimination can only be achieved through a sustained and collaborative effort across multiple sectors and stakeholders, with public health nurses playing a crucial role in this effort.

A Novel Capacity-Strengthening Intervention for Frontline Harm Reduction Workers to Support Pre-exposure Prophylaxis Awareness-Building and Promotion Among People Who Use Drugs: Formative Research and Intervention Development.

HIV prevalence among people who use drugs (PWUD) in Baltimore, Maryland, is higher than among the general population. Pre-exposure prophylaxis (PrEP) is a widely available medication that prevents HIV transmission, yet its usefulness is low among PWUD in Baltimore City and the United States. Community-level interventions to promote PrEP uptake and adherence among PWUD are limited. We describe the development of a capacity-strengthening intervention designed for frontline harm reduction workers (FHRWs) to support PrEP awareness-building and promotion among PWUD. Our study was implemented in 2 phases in Baltimore City, Maryland. The formative phase focused on a qualitative exploration of the PrEP implementation environment, as well as facilitators and barriers to PrEP willingness and uptake, among cisgender women who use drugs. This work, as well as the existing literature, theory, and feedback from our community partners, informed the intervention development phase, which used an academic-community partnership model. The intervention involved a 1-time, 2-hour training with FHRWs aimed at increasing general PrEP knowledge and developing self-efficacy promoting PrEP in practice (eg, facilitating PrEP dialogues with clients, supporting client advancement along a model of PrEP readiness, and referring clients to PrEP services). In a separate paper, we describe the conduct and results of a mixed methods evaluation to assess changes in PrEP-related knowledge, attitudes, self-efficacy, and promotion practices among FHRWs participating in the training. The pilot was developed from October to December 2021 and implemented from December 2021 through April 2022. We leveraged existing relationships with community-based harm reduction organizations to recruit FHRWs into the intervention. A total of 39 FHRWs from 4 community-based organizations participated in the training across 4 sessions (1 in-person, 2 online synchronous, and 1 online asynchronous). FHRW training attendees represented a diverse range of work cadres, including peer workers, case managers, and organizational administrators. This intervention could prevent the HIV burden among PWUD by leveraging the relationships that FHRWs have with PWUD and by supporting advancement along the PrEP continuum. Given suboptimal PrEP uptake among PWUD and the limited number of interventions designed to address this gap, our intervention offers an innovative approach to a burgeoning public health problem. If effective, our intervention has the potential to be further developed and scaled up to increase PrEP awareness and uptake among PWUD worldwide.

Development and validation of a novel scale for antiretroviral therapy readiness among pregnant women in urban Zambia with newly diagnosed HIV infection

BackgroundWomen who are newly diagnosed with HIV infection during pregnancy may not be ready to immediately initiate lifelong antiretroviral therapy (ART; called Option B +) as is recommended. Lack of “readiness” drives early disengagement from care and undermines prevention of HIV transmission to infants. Several studies have shown high early attrition of women initiating ART in pregnancy. Although poor ART uptake and adherence have been attributed to various factors including stigma, disclosure issues and structural issues, there is no standard way of determining which pregnant woman will face challenges and therefore need additional support. We developed and validated a novel ART readiness tool in Lusaka, Zambia.MethodsThe aim of this study was to develop and validate a tool that could be used to assess how ready a newly diagnosed pregnant woman living with HIV would be to initiate ART on the day of diagnosis. Using a mixed method design, we conducted this study in three public-setting health facilities in Lusaka, Zambia. Informed by qualitative research and literature review, we identified 27 candidate items. We assessed content validity using expert and target population judgment approaches. We administered the 27-item questionnaire to 454 newly diagnosed pregnant women living with HIV, who were enrolled into a randomized trial (trials number NCT02459678). We performed item reduction analysis and used Cronbach’s alpha coefficient of 0.70 as threshold for reliability.ResultsA total of 454 pregnant women living with HIV enrolled in the study between March 2017 and December 2017; 452 had complete data for analysis. The correlation coefficient between the 27 items on the completed ART readiness scale ranged from 0.31 to 0.70 while item discrimination index ranged from -0.01 to 2.38. Sixteen items were selected for the final scale, representing three domains, which we classified as “internalized and anticipated HIV stigma”, “partner support” and “anticipated structural barriers”.ConclusionWe developed and validated a tool that could be used to assess readiness of newly diagnosed women living with HIV to initiate ART. This ART readiness tool could allow clinics to tailor limited resources to pregnant women living with HIV needing additional support to initiate and remain on ART.

Barriers to Voluntary Medical Male Circumcision Uptake to Prevent HIV Transmission: A Qualitative Study among Married Men

Background: Voluntary medical male circumcision (VMMC) is a relatively new intervention that has been found to reduce sexual transmission of HIV among heterosexual partners by 60% when properly practiced. However, the poor acceptance of VMMC makes it difficult to accomplish the objectives of health policy to boost uptake. The purpose of this study was to explore the barriers to VMMC Uptake among married men in Kitgum municipality. Methods: The qualitative descriptive design was employed in this study. The purposive sampling method was used to recruit 30 married men who lived within any of the three divisions of the municipality and had been married for at least one year. Data collection was done using an in-depth interview method. Inductive content analysis was used to generate the themes and categories. Results: The study findings revealed that fear, financial uncertainty, involvement of female health workers, cultural beliefs, religious belief, sexual dissatisfaction and advanced age were barriers to voluntary medical male circumcision uptake among the married men in Kitgum municipality. Conclusion: In Kitgum municipality, VMMC Uptake is still low, but the majority of the males had sufficient knowledge about it. We found the low uptake was primarily attributed to anxiety, involvement of female health workers, financial instability, sexual unhappiness, and advanced age. There is a need for proper re-packaging of the health education messages during mobilisations to address the anticipated side effects and to clearly state the reasons for the VMMC program. There is a need for proper re-packaging of the health education messages during mobilisations to address the communication gaps and to clearly state the reasons for VMMC program. Adequate psychological preparation of the men to expect any sex of staffs working in these clinics.

The need for a health equity framework in next-generation pre-exposure prophylaxis implementation.

Pre-exposure prophylaxis (PrEP) is highly effective for prevention of HIV transmission and plays an important role in efforts to end the HIV epidemic within the next decade. However, disparities in access to PrEP might be fuelling disparities in the burden of HIV in the USA. The advent of next-generation PrEP formulations that do not involve daily regimens (eg, long-acting cabotegravir) holds potential to facilitate medication adherence, but if the roll-out of these formulations does not consider disparities in access, HIV disparities might be further widened. On the basis of US epidemiological data and informed by the Theory of Fundamental Causes of Health Disparities, we propose an equity-promoting framework to guide the implementation of daily oral and next-generation PrEP. Multilevel efforts to bolster equity in PrEP care include generating demand for next-generation PrEP formulations among marginalised groups, expanding the availability of health services providing oral and next-generation PrEP, and addressing structural and financial barriers to HIV prevention care. The aim of these strategies is to realise the potential of next-generation PrEP to provide people at high risk with effective options to prevent HIV acquisition, thereby helping to reduce both overall HIV transmission and health disparities in the USA.

Association of mental health symptoms on HIV care outcomes and retention in treatment

ObjectiveThe purpose was to examine associations between HIV care engagement and mental health symptoms among persons living with HIV (PLWH) receiving ART. This study builds upon previous findings indicating a significant association between mental health and retention in HIV care,1 while also advancing the literature by examining the impact of substance use on this link, as well as potential bidirectional associations. MethodParticipants of the current study were 493 patients who engaged in care and received antiviral therapy (ART) from Infectious Disease physicians between 2017 and 2019 in a large academic medical center. ResultsResults from hierarchical regression analyses revealed that patients who missed more days of ART medication had higher depressive symptoms, even when accounting for the effect of demographic variables and alcohol use. Further, depressive symptoms predicted significant variance in number of “no show” visits, but was not individually predictive of ““no show”” visits beyond the effect of other HIV care outcomes (e.g., number of days of medication missed). ConclusionFindings reflect linkages among HIV treatment adherence, mental health, and substance use, and highlight the need to target mental health symptoms to improve outcomes among PLWH and prevent HIV transmission.

Maternal ART throughout gestation prevents caudate volume reductions in neonates who are HIV exposed but uninfected.

Successful programmes for prevention of vertical HIV transmission have reduced the risk of infant HIV infection in South Africa from 8% in 2008 to below 1% in 2018/2019, resulting in an increasing population of children exposed to HIV perinatally but who are uninfected (HEU). However, the long-term effects of HIV and antiretroviral treatment (ART) exposure on the developing brain are not well understood. Whereas children who are HEU perform better than their HIV-infected counterparts, they demonstrate greater neurodevelopmental delay than children who are HIV unexposed and uninfected (HUU), especially in resource-poor settings. Here we investigate subcortical volumetric differences related to HIV and ART exposure in neonates. We included 120 infants (59 girls; 79 HEU) born to healthy women with and without HIV infection in Cape Town, South Africa, where HIV sero-prevalence approaches 30%. Of the 79 HEU infants, 40 were exposed to ART throughout gestation (i.e., mothers initiated ART pre conception; HEU-pre), and 39 were exposed to ART for part of gestation (i.e., mothers initiated ART post conception; HEU-post). Post-conception mothers had a mean (± SD) gestational age (GA) of 15.4 (± 5.7) weeks at ART initiation. Mothers with HIV received standard care fixed drug combination ART (Tenofovir/Efavirenz/Emtricitabine). Infants were imaged unsedated on a 3T Skyra (Siemens, Erlangen, Germany) at mean GA equivalent of 41.5 (± 1.0) weeks. Selected regions (caudate, putamen, pallidum, thalamus, cerebellar hemispheres and vermis, and corpus callosum) were manually traced on T1-weighted images using Freeview. HEU neonates had smaller left putamen volumes than HUU [β (SE) = -90.3 (45.3), p = 0.05] and caudate volume reductions that depended on ART exposure duration in utero. While the HEU-pre group demonstrated no caudate volume reductions compared to HUU, the HEU-post group had smaller caudate volumes bilaterally [β (SE) = -145.5 (45.1), p = 0.002, and -135.7 (49.7), p = 0.008 for left and right caudate, respectively]. These findings from the first postnatal month suggest that maternal ART throughout gestation is protective to the caudate nuclei. In contrast, left putamens were smaller across all HEU newborns, despite maternal ART.

Factors influencing the adoption of HIV prevention measures in low socio-economic communities of inner-city Durban, South Africa

ABSTRACT South Africa is the epicentre of the HIV pandemic. Although there have been health promotion education campaigns to reduce HIV incidence, these have not achieved the desired outcomes. When exploring the effectiveness of these campaigns, it is useful not only to examine HIV knowledge, but also to explore the relationship between that knowledge and health-related behaviour. This study aimed to determine the (1) level of knowledge of HIV prevention, (2) relationship between the level of knowledge and the adoption of these behaviours and (3) barriers to sexual behaviour change of vulnerable women in Durban’s city centre, KwaZulu-Natal, South Africa. A mixed methods approach was used to collect information from a marginalised population of women (n = 109) attending a non-governmental organisation, which provides for the needs of people from low socio-economic strata. Data were collected during September 2018 at a wellness day programme at the centre. A total of 109 women, over the age of 18 years answered the questionnaire. Knowledge of HIV transmission was high, with majority of participants correctly identifying modes of transmission. Almost all the participants (91.2%) had been tested for HIV, with 68.8% tested a minimum of three times. Despite this, sexual risk behaviour was high. Despite the high level of knowledge of HIV transmission, there was no relationship between HIV knowledge and adoption of behaviours for the prevention of HIV transmission (p = .457). However, bivariate analysis showed an association between transactional sex and living in informal housing (OR = 31.94, 95% CI: 5.65–180.63, p < .001). Living in informal housing was also associated with having multiple current sexual partners (OR = 6.30, 95% CI: 1.39–28.42, p = .02). Multivariate analysis, after adjusting for all other factors, indicated that the odds of having transactional sex was increased by 23 times in those who did not have formal housing (OR = 23.306, 95% CI: 3.97–144.59, p = .001). Qualitative responses showed that women perceived poverty as the overarching factor determining the lifestyle choices which impacted their health. They indicated a need for employment opportunities and provision of housing to alleviate both poverty as well as transactional sex. Although, participants from this study understood the benefits of the protective behaviours to prevent HIV transmission, economic and social factors do not afford this vulnerable group the opportunity nor the motivation to adopt such behaviours. In the current climate of increasing unemployment and escalating GBV, urgent interventions are needed in terms of employment opportunities and empowerment drives to prevent an increase in HIV transmission.

Psychiatric symptoms in people living with HIV: prevalences, interactions and consequences

IntroductionPeople living with HIV (PLHIV) experience higher levels of mental health issues compared to the general population. Especially depression, anxiety, impulsivity and substance use occur frequently in PLHIV. This is thought to have important consequences for quality of life, sexual risk behaviour and antiretroviral treatment (ART) adherence. Both in PLHIV as well as in the general population, divergent psychiatric symptoms often co-occur, and influence one another.ObjectivesTo assess the interrelatedness of psychiatric symptoms and their potential consequences in PLHIV.MethodsData from 1615 outpatient PLHIV using suppressive ART from the 2000HIV study (NCT03994835) were analysed. Participants reported on the severity of substance use (MATE-Q), depression and anxiety (HADS), impulsivity (BIS-11), quality of life (EQ-5D-5L), ART adherence (MASS-8) and sexual risk behaviour. For these variables, prevalence rates and mean scores were calculated. After binarizing the data, an Ising network model was constructed. Using this network, interrelations between psychiatric symptoms were assessed, the centrality of symptoms was estimated and connections with clinical consequences were explored.ResultsIn our cohort of PLHIV, the increased prevalence of substance use was most pronounced, as shown by a prevalence rate of 28.7% for smoking, 13.6% for cannabis use, 11.1% for heavy alcohol drinking and 9.2% for ecstasy use in the past month. The network analysis revealed that symptoms of depression and anxiety were most strongly interrelated. The depressive symptom “feeling slowed down” was one of the most central symptoms, and was most strongly connected with quality of life. Substance use was associated with a higher occurrence of sexually transmitted diseases, and this relationship was mediated by a higher number of sexual partners. Notably, ART adherence did not display any connections with depression, anxiety, impulsivity or substance use.Image:ConclusionsThe high occurrence of substance use and its link with sexual risk behaviour, emphasizes it’s role as a potential target for prevention of HIV transmission. Contrary to general assumption, psychiatric symptoms are not associated with lower levels of ART adherence in our cohort. Treatment of depression in PLHIV might be improved by focussing on the symptom of feeling slowed down, since this symptom was most strongly connected with quality of life.Disclosure of InterestE.

High Prevalence of Syphilis and Syphilis/HIV Coinfection among Men Who Have Sex with Men Who Attend Meeting Places in Mexico.

Men who have sex with men (MSM) are disproportionately affected by syphilis, HIV, and syphilis/HIV coinfection. Antiretroviral therapy (ART) prevents HIV transmission but does not impede the spread or acquisition of syphilis. Information about syphilis/HIV coinfection among MSM is scarce. We aimed to determine the prevalence of syphilis/HIV coinfection in a national sample of MSM who attend meeting places (such as movies, clubs, gay bars, saunas, shopping malls, and others referred to by the same MSM participants of the study) in Mexico to evaluate factors associated with syphilis, and to compare the prevalence rates of syphilis between the current survey and DGE data. We performed a laboratory diagnosis to determine the rates of syphilis and HIV among the included MSM. The national and regional prevalence of syphilis was calculated. HIV and coinfection prevalence were determined only for the survey. All prevalence rates included 95%CIs. Descriptive, bivariate, and multivariate analyses were performed. The national prevalence rates of syphilis, HIV, and coinfection were 15.2%, 10.2%, and 5.7%, respectively. The region with the highest prevalence rate was Mexico City (39.4%). The center region, minimal "goods" (i.e., a minimal number of material possessions such as a car or dryer, etc., which served as a proxy for low economic income level), use of "inhalant drugs", "HIV infection", "sexual intercourse" only with men, "rewarded sex", and "youngest age at first sexual encounter or debut" were risk factors for syphilis. In general, regional prevalence of syphilis was higher in the survey (2013) and DGE data from 2019 than in the DGE data from 2013. Similar to other countries, Mexico needs to assess elements around not only syphilis and HIV infections but also syphilis/HIV coinfection, and preventive measures focusing on MSM are needed.
