Awareness of, willingness to use, and experiences with Pre-exposure prophylaxis among youth in Nigeria

BackgroundYouth (ages 14–24) in Nigeria have disproportionately high rates of new HIV infection. Pre-exposure prophylaxis could substantially reduce new infections among youth but has not been scaled up. This cross-sectional study aimed to assess Pre-exposure prophylaxis awareness, willingness to use, and prior use of Pre-exposure prophylaxis among youth in Nigeria.MethodsThis is a secondary analysis of cross-sectional data from a quasi-experimental pilot study (clinical trial NCT04070287). The analysis focused on Pre-exposure prophylaxis awareness, willingness to use, and prior use among 324 youth recruited between September 2019 to March 2020. Descriptive statistics were calculated as frequencies and percentages for categorical variables and means and standard deviations for continuous variables.ResultsOf the 324 participants, the mean age and standard deviation were 21.17 (± 2.20) years. The majority were 20–24 years old (75.9%) and male (57.7%). Only 30.7% used condoms consistently over three months. Regarding Pre-exposure prophylaxis awareness and willingness, 62.6% had never heard of Pre-exposure prophylaxis, and 158 (50.1%) reported willingness to use Pre-exposure prophylaxis. Only 10 (3.2%) reported having used Pre-exposure prophylaxis.ConclusionNigerian youth have low awareness of and prior use of Pre-exposure prophylaxis. Given the gap between prior use and willingness to use Pre-exposure prophylaxis, our findings suggest missed opportunities to prevent new HIV infections among youth in Nigeria. Efforts to increase awareness and uptake of Pre-exposure prophylaxis among this population should consider youth-led Pre-exposure prophylaxis outreach efforts and effectively communicate the benefits of Pre-exposure prophylaxis to this population.Trial RegistrationNCT04070287, the Date of registration of the trial is 20-07-2019.

Drug Use Behaviors and the Risk of HIV Infection Among Drug Users in China Between 2014 and 2021: Cross-Sectional Study.

Drug users are a high-risk group for HIV infection and are prominent HIV carriers. Given the emergence of new drugs, we explored current drug-using behaviors, HIV infections, and the correlation between drug-using behaviors and HIV infection risk among drug users from 2014 to 2021. We aimed to identify the prevalence of HIV infection risk among drug users and explore drug use behaviors based on the updated data, which could provide evidence for the precision of HIV prevention strategies among drug users. Data were collected from sentinel surveillance of drug users in rehabilitation centers and communities in Hangzhou (2014-2021), including sociodemographic characteristics, HIV awareness, drug use, risky sexual behaviors, and HIV infection status. Multivariate logistic regression was used to identify the factors influencing HIV infection and risky sexual behaviors among drug users. In total, 5623 drug users (male: n=4734, 84.19%; age: mean 38.38, SD 9.94 years) were included. New drugs dominated among the participants (n=3674, 65.34%). The main mode of drug use was noninjection (n=4756, 84.58%). Overall, for 27.45% (n=1544) of injected drugs in the last month before the investigation, the average daily injection frequency was 3.10 (SD 8.24). Meanwhile, 3.43% of participants shared needles. The incidence of sexual behaviors after drug use was 33.13% (n=1863), with 35.75% (n=666) of them using a condom in the last time. Overall, 116 participants tested positive for HIV antibodies (infection rate=2.06%). New drug users exhibited more postuse sexual behaviors than traditional drug users (odds ratio [OR] 7.771, 95% CI 6.126-9.856; P<.001). HIV-aware drug users were more likely to engage in risky sexual behaviors (OR 1.624, 95% CI 1.152-2.291; P=.006). New-type drug users were more likely to engage in unprotected sexual behavior (OR 1.457, 95% CI 1.055-2.011; P=.02). Paradoxically, drug users with greater HIV awareness were more prone to engaging in unprotected sexual behavior (OR 5.820, 95% CI 4.650-7.284; P<.001). Women engaged less in unprotected sex than men (OR 0.356, 95% CI 0.190-0.665; P=.001). HIV rates were higher among injecting drug users (OR 2.692, 95% CI 0.995-7.287; P=.04) and lower among drug users who used condoms during recent sex than those who did not (OR 0.202, 95% CI 0.076-0.537; P=.001). Higher education levels were associated with higher HIV infection rates. However, there was no significant correlation between HIV cognition level and HIV infection. New drug types and noninjection were the main patterns in last 7 years. Using new types of drugs, rather than traditional drugs, was associated with an increased risk of HIV infection. Injection drug use was a risk factor for HIV infection. HIV awareness among drug users was high, but the incidence of risky sexual behaviors remained high. Therefore, it is important to promote the behavioral transformation of high-risk populations from cognition to attitude, and then to taking protective measures.

Characteristics of women on opioid substitution therapy in primary healthcare in Tshwane (South Africa): a retrospective observational study.

Women who use drugs face specific challenges compared to men, such as higher rates of HIV infection, unsafe injecting practices and intimate partner violence. However, this population's access to drug dependence treatment and gender-sensitive interventions remains limited, leading to unmet needs and increased vulnerability. To investigate the characteristics of and associations with retention in care among women on opioid substitution therapy (OST) in a community based primary care setting. A descriptive observational study within the Community Orientated Substance Use Programme in Tshwane, South Africa. Data from 199 women (>18 years) on OST was extracted from an electronic database and paper-based files. Data was analysed descriptively, and inferential analysis looked for association of variables with retention on OST for≥6 months. Majority of participants were unemployed, with 44.3% falling within the 20-29 years age range. During the initiation and course of OST, 39.2% of women experienced intimate partner violence, and 19.0% were pregnant. Retention on OST was significantly associated with increasing age at initiation (p=0.047), knowledge of HIV status (p=0.029), an increase in the ASSIST score (p=0.023), and methadone dose (p<0.001). Factors such as race, employment status, health system level, pregnancy, intimate partner using substances, intimate partner violence, route of administering opioids, and having tuberculosis and/or hepatitis C exposure did not show a significant relationship with retention on OST (p>0.05). This study reveals specific vulnerabilities in women receiving OST, emphasising the need for the integration of interventions to address reproductive health, violence mitigation, infectious disease and polydrug use into care.

Teachers navigating the sociocultural challenges of teaching sexuality education to South African learners

Objective: Globally, South Africa has the highest rate of HIV infection, nevertheless, society and communities seem hesitant to entrust teachers with the responsibility to teach their children about sexuality issues. This study examined how Further Education and Training Life Orientation teachers navigate the sociocultural complexities of teaching sexuality education. Design: A qualitative, narrative study was conducted. Data were generated using narrative frames, collages, and lesson observations. Setting: Six Life Orientation teachers from six schools in the province of KwaZulu-Natal, South Africa participated. Results: Life Orientation teachers faced a range of sociocultural challenges when teaching sexuality education. The following strategies were used to mitigate these challenges: avoiding teaching about contradicting cultural and religious beliefs; using social media platforms; involving specialists, peer educators and role models; and adopting pastoral and parental roles. Conclusion: Collaborative opportunities between Life Orientation teachers, specialists, role models and community members or organisations could offer a supportive role and influence the teaching of sexuality education positively. Social media platforms and innovative teaching strategies could enhance the quality and teaching of sexuality education.

Amphotericin B resistance in Leishmania amazonensis: In vitro and in vivo characterization of a Brazilian clinical isolate.

In Brazil, Leishmania amazonensis is the etiological agent of cutaneous and diffuse cutaneous leishmaniasis. The state of Maranhão in the Northeast of Brazil is prevalent for these clinical forms of the disease and also has high rates of HIV infection. Here, we characterized the drug susceptibility of a L. amazonensis clinical isolate from a 46-year-old man with diffuse cutaneous leishmaniasis coinfected with HIV from this endemic area. This patient underwent several therapeutic regimens with meglumine antimoniate, liposomal amphotericin B, and pentamidine, without success. In vitro susceptibility assays against promastigotes and intracellular amastigotes demonstrated that this isolate had low susceptibility to amphotericin B, when compared with the reference strain of this species that is considered susceptible to antileishmanial drugs. Additionally, we investigated whether the low in vitro susceptibility would affect the in vivo response to amphotericin B treatment. The drug was effective in reducing the lesion size and parasite burden in mice infected with the reference strain, whereas those infected with the clinical isolate and a resistant line (generated experimentally by stepwise selection) were refractory to amphotericin B treatment. To evaluate whether the isolate was intrinsically resistant to amphotericin B in animals, infected mice were treated with other drugs that had not been used in the treatment of the patient (miltefosine, paromomycin, and a combination of both). Our findings demonstrated that all drug schemes were able to reduce lesion size and parasite burden in animals infected with the clinical isolate, confirming the amphotericin B-resistance phenotype. These findings indicate that the treatment failure observed in the patient may be associated with amphotericin B resistance, and demonstrate the potential emergence of amphotericin B-resistant L. amazonensis isolates in an area of Brazil endemic for cutaneous leishmaniasis.

Comparing PrEP initiation rates by service delivery models among high risk adolescent boys and young men in KwaZulu-Natal, South Africa: findings from a population-based prospective study

IntroductionPre-exposure prophylaxis (PrEP) is an HIV prevention strategy that can reduce the risk of HIV acquisition by more than 90% if taken consistently. Although South Africa has been implementing PrEP since 2016, initially for selected population groups before expanding access to more people, there is a dearth of research focused on PrEP among adolescent boys and young men (ABYM), despite them experiencing high rates of HIV infection. To address this gap, we compared PrEP initiation rates by service delivery points (SDPs) among ABYM in KwaZulu-Natal, South Africa.MethodsWe conducted a population-based prospective study in 22 SDPs from July 2021 to July 2022 in KwaZulu-Natal, South Africa. Sexually active ABYM aged 15–35 years who tested HIV negative were recruited at purposively selected PrEP SDPs (i.e., healthcare facilities, secondary schools and Technical Vocational Education and Training (TVET) colleges, and community-based youth zones). We collected baseline quantitative data from each participant using self-administered electronic questionnaires built into REDCap, including demographic information such as age, sex, employment status and level of education, as well as PrEP initiation outcomes. We extracted data from REDCap and exported it to Stata version 17.0 for analysis, and then eliminated discrepancies and removed duplicates. We described baseline characteristics using summary and descriptive statistics (median, interquartile range [IQR] and proportions) and reported PrEP initiation proportions overall and by SDPs.ResultsThe study included 1104 ABYM, with a median age of 24 years (interquartile range (IQR): 21–28)). Almost all participants were black African (n = 1090, 99%), with more than half aged 15–24 years (n = 603, 55%) and 45% (n = 501) aged 25–35 years. The majority (n = 963; 87%) had attained a secondary level of education. Overall PREP initiation rate among adolescent boys and young men was low: among 1078 participants who were eligible for PrEP, 13% (n = 141) were started on PrEP. Among the participants who were initiated on PrEP, over three quarters (78%, n = 58) were initiated from high schools, compared with community-based youth zones (40%, n = 37), TVET colleges (26%, n = 16) and healthcare facilities (4%, n = 30).ConclusionsThis study provided evidence suggesting that expanding PrEP services to non-traditional settings, such as high schools, TVET colleges, and community-based organizations, may have a potential to increase PrEP access among ABYM in South Africa.

Barriers to HIV Pre-Exposure Prophylaxis Use Among Women in the US: A Systematic Literature Review

Introduction: The high acquisition rate of HIV infection among women in the United States is concerning. Despite the FDA approving the first pre-exposure prophylaxis (PrEP) drug in 2012, PrEP utilization remains significantly lower among women. This literature review aims to analyze the current body of research concerning HIV PrEP usage among women in the US. Methods: A search of three medical databases was conducted. After the screening, 19 studies were selected for analysis. A risk of bias assessment was performed. Results: A final set of records meeting the inclusion criteria (n=19) was included in the review for data collection and analysis. The study methodology for these research articles included interview-based designs (semi-structured and brief formats) in 1-on-1 meetings, focus groups, surveys, and retrospective data analysis. Participants' HIV risk characteristics were reported by way of sexual behavior, drug use, combined sexual behavior and drug use, and living in a high HIV rate neighborhood. Nineteen themes were identified and organized into three categories: (1) Common medication administration barriers, (2) PrEP-specific barriers, and (3) Situational barriers. The three most common themes reported by participants included a concern about side effects, low perceived risks of HIV, and lack of PrEP information. The CASP Qualitative Checklist and risk assessment summary showed acceptable validity among studies. Discussion: This review identifies significant barriers hindering women's PrEP utilization, which would benefit from more prevalent stakeholder communication and education directed to at-risk populations. Inconsistently reported descriptive data on participants and the low patient populations make it difficult to generalize outcomes.

Prevalence of HIV, HBV and HCV among livestock merchants and slaughterhouse workers in Ibadan, Nigeria.

Most studies on viral infections among livestock handlers have focused on occupational exposure from inadvertent contact with infected animals. Consequently, little emphasis is given to the effect of their lifestyle on the acquisition of other blood-borne viruses. To determine the prevalence and assess risk factors for HIV, HBV and HCV infections among livestock handlers in Ibadan, Nigeria. Blood samples were collected from 265 livestock handlers between October 2016 to April 2017 in Ibadan. The samples were tested for the presence of antibodies to HIV and HCV; and surface antigen to HBV using ELISA. Structured questionnaire was administered to collect information on risk factors associated with the transmission of these viruses. Data analysis was carried out using Chi-square test and logistic regression to determine the association between risk factors and predictors of infection (p < 0.05). Of 265 participants, 11 (4.2%), 29 (10.9%) and 13 (4.9%) individuals tested positive for HIV, HBV and HCV infections respectively. Two (0.8%) of the participants were coinfected with HIV and HBV while 1(0.4%) was coinfected with both HBV and HCV. Individuals who travelled frequently in the course of Livestock trades had a higher rate of HIV infection. A high Infection with HIV, HBV and HCV is common among the study participants. There is a need for continued surveillance and awareness creation on preventive measures against these viruses.

The Psychological and Physical Effects of Sex Taboos

The objective of this investigation was to find the physical and psychological effects that sex taboos directly or indirectly cause in individuals. This investigation's importance is reflected in how sex taboos are such an integral part of everything, from culture, art, clothing, architecture, medical care, teachings, and language. Sex taboos are present in almost every person's life, and it is essential first to illustrate the effects they have on people to be able to take the first step into helping individuals and irradicating sex taboos. This investigation proves that sex taboos, or situations caused by the upholding of these norms, lead to anxiety, depression, shame, guilt, risky sexual behavior, higher HIV infection rates, higher teen pregnancy rates, incorrect sex ed, damaged parent-child relationships, emotional distress, mistreatment and misdiagnosis of malnutrition, prejudice, isolation, medical professionals perpetuating misinformation and myths, violent sexual behavior, and suicide.

Youth Ending the HIV Epidemic (YEHE): Protocol for a pilot of an automated directly observed therapy intervention with conditional economic incentives among young adults with HIV.

Young adults have a disproportionately high rate of HIV infection, high rates of attrition at all stages of the HIV care continuum, and an elevated probability of disease progression and transmission. Tracking and monitoring objective measures of antiretroviral therapy (ART) adherence in real time is critical to bolster the accuracy of research data, support adherence, and improve clinical outcomes. However, adherence monitoring often relies on self-reported and retrospective data or requires additional effort from providers to understand individual adherence patterns. In this study, we will monitor medication-taking using a real-time objective measure of adherence that does not rely on self-report or healthcare providers for measurement. The Youth Ending the HIV Epidemic (YEHE) study will pilot a novel automated directly observed therapy-conditional economic incentive (aDOT-CEI) intervention to improve ART adherence among youth with HIV (YWH) in California and Florida who have an unsuppressed HIV viral load. The aDOT app uses facial recognition to record adherence each day, and then economic incentives are given based on a participant's confirmed adherence. We will enroll participants in a 3-month pilot study to assess the feasibility and acceptability of the aDOT-CEI intervention using predefined metrics. During and after the trial, a subsample of the pilot participants and staff/providers from participating AIDS Healthcare Foundation (AHF) clinics will participate in individual in-depth interviews to explore intervention and implementation facilitators and barriers. YEHE will provide data on the use of an aDOT-CEI intervention to improve adherence among YWH who are not virologically suppressed. The YEHE study will document the feasibility and acceptability and will explore preliminary data to inform a trial to test the efficacy of aDOT-CEI. This intervention has the potential to effectively improve ART adherence and virologic suppression among a key population experiencing health disparities. The trial registration number is NCT05789875.

Adapting Provider Training and Pre-Exposure Prophylaxis Advertising to Increase Pre-Exposure Prophylaxis Awareness and Uptake Among Black Cisgender Women.

Black cisgender women (hereafter referred to as "women") have disproportionately high rates of HIV infection yet low rates of pre-exposure prophylaxis (PrEP) utilization. Barriers to PrEP uptake exist at the system, provider, and individual/client level. To learn how existing training and advertising can be adapted to address race- and sex-based gaps within PrEP service delivery, we conducted focus groups with providers and Black women. Participants were recruited at three health care organizations in the Midwest and South, screened for eligibility, and consented verbally. Focus groups occurred from August 2022 to February 2023. Women were asked about their knowledge and thoughts on PrEP. Providers were asked about factors influencing their decision-making about PrEP. A codebook was developed based on the Consolidated Framework for Implementation Research. Transcripts were coded using the Stanford Lightning Report Method. We completed four focus groups with 10 providers and 9 focus groups with 25 women. Three major themes emerged: (1) low comfort level and limited cultural sensitivity/competency among providers discussing HIV risk and PrEP with Black women, (2) women's concerns about PrEP's side effects and safety during pregnancy, and (3) lack of Black women representation in PrEP advertisement/educational materials. In addition, women in the South reported general medical mistrust and specific misconceptions about PrEP. PrEP trainings for providers need detailed information about the safety of PrEP for women and should include role-playing to enhance cultural competency. Likewise, PrEP advertisements/materials should incorporate information regarding side effects and images/experiences of Black women to increase PrEP awareness and uptake among this population. Clinical Trial Registration Number: NCT05626452.

Metabolomic profiling of preterm birth in pregnant women living with HIV

BackgroundPreterm birth is a leading cause of death in children under the age of five. The risk of preterm birth is increased by maternal HIV infection as well as by certain antiretroviral regimens, leading to a disproportionate burden on low- and medium-income settings where HIV is most prevalent. Despite decades of research, the mechanisms underlying spontaneous preterm birth, particularly in resource limited areas with high HIV infection rates, are still poorly understood and accurate prediction and therapeutic intervention remain elusive.ObjectivesMetabolomics was utilized to identify profiles of preterm birth among pregnant women living with HIV on two different antiretroviral therapy (ART) regimens.MethodsThis pilot study comprised 100 mother-infant dyads prior to antiretroviral initiation, on zidovudine monotherapy or on protease inhibitor-based antiretroviral therapy. Pregnancies that resulted in preterm births were matched 1:1 with controls by gestational age at time of sample collection. Maternal plasma and blood spots at 23–35 weeks gestation and infant dried blood spots at birth, were assayed using an untargeted metabolomics method. Linear regression and random forests classification models were used to identify shared and treatment-specific markers of preterm birth.ResultsClassification models for preterm birth achieved accuracies of 95.5%, 95.7%, and 80.7% in the untreated, zidovudine monotherapy, and protease inhibitor-based treatment groups, respectively. Urate, methionine sulfone, cortisone, and 17α-hydroxypregnanolone glucuronide were identified as shared markers of preterm birth. Other compounds including hippurate and N-acetyl-1-methylhistidine were found to be significantly altered in a treatment-specific context.ConclusionThis study identified previously known as well as novel metabolomic features of preterm birth in pregnant women living with HIV. Validation of these models in a larger, independent cohort is necessary to ascertain whether they can be utilized to predict preterm birth during a stage of gestation that allows for therapeutic intervention or more effective resource allocation.

Oportunidades perdidas en la detección temprana de la infección por VIH en pacientes con infecciones de transmisión sexual: un estudio de vida real

IntroductionSexually transmitted diseases such as cervicitis, proctitis and urethritis are associated with high rates of HIV infection. When these pathologies are suspected, HIV serology should be requested. Material and methodsA Retrospective study was performed during 2018 at the Hospital Costa del Sol (Marbella, Málaga, Spain). HIV serologies requested in patients who were asked for PCR for Chlamydia trachomatis and Neisseria gonorrhoeae were reviewed. ResultsA total of 1818 patients were evaluated, in which HIV serology was performed in 44.7%, of which 14 (1.7%) were positive. The remaining 55.3% were missed diagnostic opportunities. ConclusionsC.trachomatis and N.gonorrhoeae infections are associated with a high rate of occult HIV infection. The degree of suspicion of HIV in this population remains low and it is essential that it be reinforced in the presence of the possibility of infection by these pathologies.

Current characteristics of the HIV/syphilis co-infection epidemic

Syphilis, alongside with HIV infection, remains a pressing public health issue due to its widespread prevalence among high-risk groups: men who have sex with men (MSM), transgender women, and female sex workers (FSW). The MSM group shows a disproportionately high prevalence rate of HIV infection, with cases of syphilis/HIV co-infection also on the rise in this population. The increase in these co-infection cases deserves special attention. According to the literature, the rate of HIV infection among syphilis patients averages 15.7%. In addition, it varies significantly, going from 3% in the general population to 90% among MSM. Epidemiological surveillance data showed an increase in cases of HIV/syphilis co-infection in the MSM group, with the proportion of co-infection patients varying from 30 to 60% depending on the region. This syndemia can be explained by the fact that syphilis can contribute to HIV transmission and acquisition. The risk of HIV infection is 2 to 5 times higher among people with syphilis. At the same time, STDs are more and more difficult to control as the Internet and dating applications have made it easier to find potential sex partners. Given the high prevalence rate of syphilis among MSM, screening, diagnosis and treatment of STDs in this population should be a health care priority. Early detection and timely treatment of these socially significant diseases play an important role in epidemic prevention measures.

Risky sexual behaviors and associated factors among adult patients on antiretroviral treatment at Mankweng Hospital in Limpopo Province, South Africa.

Worldwide, it is estimated that 38 million people are HIV-positive and that over 36 million people have died from the virus. In South Africa, the prevalence of HIV was reported to be 20.6% with Limpopo Province having 17% HIV. Given the high rate of new HIV infection in Limpopo, there is therefore a need to assess factors promoting risky sexual behavior among people living with HIV in order to help design and develop behavioral interventions aimed at reducing risky behaviors among people living with HIV. This was a quantitative cross-sectional prospective study, conducted in Mankweng Hospital. The study consisted of 116 participants of which 40 were males and 76 were females aged 18 years and above. The participants were selected using purposive sampling. The data was analyzed using Statistical Package for Social Sciences version 27. A comparison of proportions was performed using Chi-Square. The association between risky sexual practice and sociodemographic factors was analyzed using multivariate logistic regression. The proportion of risky sexual practices in the total population was 48.3%. Participants who were married, those aged 35-44, and those with tertiary qualifications were more likely to engage in risky sexual practices. Multivariate logistic regression showed widowed participants were less likely to practice risky sexual practices. The present study reported a high prevalence of risky sexual practices of 48.3%. Risky sexual behavior was determined by age, marital status, and level of education. The proportion of married participants was higher in risky sexual behavior. Based on the findings of the present study, it is recommended that targeted interventions and educational programs should be implemented to reduce risky sexual behavior among married individuals, individuals aged 35-44, and individuals with tertiary qualifications.

Early infant diagnosis of HIV infection: a mixed-method study of uptake and challenges at primary health centers in Lagos State, Nigeria

IntroductionNigeria has a low uptake of early infant diagnosis (EID) of HIV despite its high pediatric HIV infection rate. Efforts to increase the EID of HIV have been limited by many factors. This research assessed EID uptake and challenges service providers experienced in providing routine care for HIV-exposed infants.MethodsThis is a mixed-method study at primary health centers (PHCs) in Lagos state, Nigeria. The quantitative component of the research was a review of the PMTCT Infant Follow-up Register at a purposive sample of 22 PHCs of Lagos State. The number of HIV-exposed infants (HEIs) returned for a dried blood sample (DBS) collection, date of collection, and the infant’s EID results for one year preceding the study were captured on Research Electronic Data Capture (RedCap). In-depth interviews were conducted with service providers purposively selected per participating PHC. Electronic transcripts were analyzed using MAXQDA 2020 (VERBI Software, 2019).ResultsTwenty-two Lagos State primary health centers participated in the research. Fifteen PHCs (68.2%) had PMTCT HIV counseling and Infant follow-up registers. Documentation of DBS sample collection was observed in 12 (54.6%) PHCs. Both DBS sample collection and EID results documentation were observed in only nine (40.9%) PHCs. In-depth interviews revealed both maternal and health systems’ challenges to EID. The denial of HIV status was the only maternal factor reported as a barrier against the use of EID services. Health systems challenges include unavailability of EID services, uncertainty regarding whether EID is performed in a facility, referral to secondary health facilities for EID services (leading to losses to follow-up), and delay in getting results of EID. Task-shifting of DBS collection by nurses was suggested as means to increase access to EID services.ConclusionsThere is a need to expand EID services and address women’s denial of HIV infection. Counseling women and linkage to available services are emphasized. Re-training of health workers on DBS collection and proper documentation of EID services were noted as key to improving the implementation of early infant diagnosis of HIV in the state.

Stimulant use, HIV, and immune dysregulation among sexual minority men

BackgroundSexual minority men (SMM) report high rates of stimulant use (e.g., crystal methamphetamine, cocaine) and HIV infection. Stimulant use contributes to immune dysfunction, which enhances risk for HIV acquisition and pathogenesis. Research is needed to examine the independent and interactive relationships of stimulant use and HIV infection with systemic immune dysregulation among SMM, especially during the COVID-19 pandemic. MethodsFrom 2020–2022, 75 SMM in Miami, Florida with and without HIV completed an online survey and provided biospecimens to assess HIV status and viral load (VL), recent stimulant use, and soluble markers of immune activation and inflammation in plasma, including soluble CD14 (sCD14) and elevated high-sensitivity C-reactive protein (hs-CRP > 1.0mg/L). Sociodemographics and prior SARS-CoV-2 infection were compared across HIV status/stimulant use groups. Moderation models examined the independent and interactive associations of stimulant use and HIV status with sCD14 and elevated hs-CRP. ResultsThirty participants were persons living with HIV (PWH) (50% with stimulant use), and 45 were HIV-negative (44% with stimulant use). SARS-CoV-2 infection was not associated with stimulant use/HIV groups or immune outcomes. HIV-negative SMM without stimulant use had lower sCD14 compared to other SMM, as well as lower odds of elevated hs-CRP compared to PWH who used stimulants. Stimulant use showed independent associations with immune dysregulation that persisted after controlling for HIV status and VL, whereas HIV status was only independently associated with elevated hs-CRP in one model not controlling for VL. ConclusionsAmong SMM, stimulant use was independently associated with elevated immune activation and inflammation.

Protocol for WeExPAnd: a prospective, mixed-methods pilot demonstration study to increase access to pre-exposure prophylaxis among women vulnerable to HIV infection in the Southern USA

IntroductionAfrican American women (AA), particularly those living in the Southeastern USA, experience disproportionately high rates of HIV infection. Pre-exposure prophylaxis (PrEP) is a highly effective HIV prevention tool that may...

Synthesis of end-user research to inform future multipurpose prevention technologies in sub-Saharan Africa: a scoping review.

Women in sub-Saharan Africa (SSA) experience disproportionately high rates of HIV infection and unintended pregnancy compared to their age-matched counterparts in other regions of the world. Multipurpose prevention technologies (MPTs) that offer protection against HIV and unintended pregnancy in a single product stand to address these dual sexual and reproductive health needs simultaneously. The aim of this scoping review is to identify factors that are important for optimizing the likelihood of MPT adoption by end users in SSA. Study inclusion criteria included MPT research (HIV and pregnancy prevention dual indication) published or presented in English from 2000 to 2022 and conducted in SSA amongst end-users (women aged 15-44), male partners, health care providers, and community stakeholders. References were identified by searching peer reviewed literature, grey literature, conference presentations (2015-2022), grant databases, and outreach to MPT subject matter experts. Of 115 references identified, 37 references met inclusion criteria and were extracted for analysis. A narrative synthesis approach was used to summarize findings within and across MPT products. Studies were identified from six countries in SSA and a substantial proportion included a South African (n = 27) and/or Kenyan (n = 16) study site. Most studies utilized a qualitative study design (n = 22) and evaluated MPT acceptability and preferences by presenting hypothetical products through images or a list of product attributes (n = 21). The vaginal ring (n = 20), oral tablet (n = 20), and injection (n = 15) were examined most frequently. Across studies, there was high acceptability and demand for an HIV and pregnancy prevention MPT. End users valued choice in prevention product type as well as discreetness and long-acting options. Provider counseling and community sensitization were reported as essential for future introduction of novel MPT delivery forms. Recognizing the heterogeneity of women's preferences and changing reproductive and sexual health needs over the life course, choice is important in the delivery of pregnancy and HIV prevention products as well as amongst MPT products with distinct product profiles. End user research with active MPTs, vs. hypothetical or placebo MPTs, is necessary to advance understanding of end-user preferences and acceptability of future products.

The role of β-2-microglobulin and cystatin C as urinary biomarkers of focal segmental glomerulosclerosis in the setting of paediatric HIV infection

Background. Africa has the highest rate of HIV infection, and HIV-associated nephropathy (HIVAN) is one of the most frequent kidneydiseases observed in children. HIVAN in children usually presents as a form of nephrotic syndrome, predominantly focal segmentalglomerulosclerosis (FSGS) on histopathology, that often leads to chronic kidney failure.Objective. This study determined the urinary concentrations of β-2-microglobulin (β2M) and cystatin C proteins in children with HIVANand primary FSGS.Methods. The study group comprised 34 children; 14 with HIVAN and 20 with primary FSGS. The control groups were 20 HIV-positiveand 20 HIV-negative children with no kidney disease. Urine samples collected from these 74 children were stored at -80°C. Bio-Plextechnology was used to analyse the urinary protein concentration of cystatin C and β2M.Results. A significant increase in urinary β2M levels was observed in the HIVAN group compared with the HIV-negative group(p=0.0240). No other statistically significant differences in urinary β2M concentrations were noted across the study groups. Urinarycystatin C levels were significantly increased in primary FSGS children compared with both HIV-negative (p=0.0041) and HIV-positivecontrols (p=0.0256). Urinary cystatin C displayed a significant increase in the primary FSGS compared with the HIVAN group (p=0.0150).No significant differences in urinary cystatin C levels were noted in the HIVAN group compared with the HIV-negative and HIV-positivecontrol groups.Conclusion. Urinary cystatin C has promising prognostic value to predict primary FSGS from HIVAN.
