Impact of coronavirus disease 2019-related clinic closures on HIV incidence in young adult MSM and transgender women in Kenya.

Little is known about the impact that the COVID-19 pandemic had on risk of HIV acquisition in sub-Saharan Africa. We assessed the impact of COVID-19-related clinic closures on HIV incidence in a cohort of gay, bisexual, and other men who have sex with men (MSM) and transgender women in Kenya. MSM and transgender women enrolled in a prospective, multicentre cohort study were followed quarterly for HIV testing, behaviour assessments, and risk. We estimated the HIV incidence rate and its 95% credible intervals (CrI) among participants who were HIV-negative before COVID-19-related clinic closure, comparing incidence rate and risk factors associated with HIV acquisition before vs. after clinic reopening, using a Bayesian Poisson model with weakly informative priors. A total of 690 (87%) participants returned for follow-up after clinic reopening (total person-years 664.3 during clinic closure and 1013.3 after clinic reopening). HIV incidence rate declined from 2.05/100 person-years (95% CrI = 1.22-3.26, n = 14) during clinic closures to 0.96/100 person-years (95% CrI = 0.41-2.07, n = 10) after clinic reopening (IRR = 0.47, 95% CrI = 0.20-1.01). The proportion of participants reporting hazardous alcohol use and several sexual risk behaviours was higher during clinic closures than after clinic reopening. In multivariable analysis adjusting for study site and participant characteristics, HIV incidence was lower after clinic reopening (IRR 0.57, 95% CrI = 0.23-1.33). Independent risk factors for HIV acquisition included receptive anal intercourse (IRR 1.94, 95% CrI = 0.88-4.80) and perceived risk of HIV (IRR 3.03, 95% CRI = 1.40-6.24). HIV incidence during COVID-19-related clinic closures was moderately increased and reduced after COVID-19 restrictions were eased. Ensuring access to services for key populations is important during public health emergencies.

Evaluating the impact of point-of-care HIV viral load assessment on linkage to care in Baltimore, MD: a randomized controlled trial

BackgroundIntegration of a sensitive point-of-care (POC) HIV viral load (VL) test into screening algorithms may help detect acute HIV infection earlier, identify people with HIV (PWH) who are not virally suppressed, and facilitate earlier referral to antiretroviral therapy (ART), or evaluation for pre-exposure prophylaxis (PrEP). This report describes a randomized clinical trial sponsored by the Centers for Disease Control and Prevention (CDC): “Ending the HIV Epidemic Through Point-of-Care Technologies” (EHPOC). The study’s primary aim is to evaluate the use of a POC HIV VL test as part of a testing approach and assess the impact on time to linkage to ART or PrEP. The study will recruit people in Baltimore, Maryland, including patients attending a hospital emergency department, patients attending an infectious disease clinic, and people recruited via community outreach. The secondary aim is to evaluate the performance characteristics of two rapid HIV antibody tests approved by the United States Food and Drug Administration (FDA).MethodsThe study will recruit people 18 years or older who have risk factors for HIV acquisition and are not on PrEP, or PWH who are not taking ART. Participants will be randomly assigned to either the control arm or the intervention arm. Participants randomized to the control arm will only receive the standard-of-care (SOC) HIV screening tests. Intervention arm participants will receive a POC HIV VL test in addition to the SOC HIV diagnostic screening tests. Follow up will consist of an interim phone survey conducted at week-4 and an in-person week-12 visit. Demographic and behavioral information, and oral fluid and blood specimens will be collected at enrollment and at week-12. Survey data will be captured in a Research Electronic Data Capture (REDCap) database. Participants in both arms will be referred for either ART or PrEP based on their HIV test results.DiscussionThe EHPOC trial will explore a novel HIV diagnostic technology that can be performed at the POC and provide viral assessment. The study may help inform HIV testing algorithms and contribute to the evidence to support same day ART and PrEP recommendations.Trial registrationNIH ClinicalTrials.gov NCT04793750.

Distinct mucosal and systemic immunological characteristics in transgender women potentially relating to HIV acquisition.

Transgender women (TGW) are disproportionally affected by HIV infection, with a global estimated prevalence of 19.9%, often attributed to behavioral risk factors, with less known about biological factors. We evaluated potential biological risk factors for HIV acquisition in TGW at the sites of viral entry by assessing immune parameters of the neovaginal surface and gut mucosa. The neovagina in TGW, compared with the vagina in cisgender women (CW), shows distinct cell composition and may pose a more inflammatory environment, evidenced by increased CD4+ T cell activation and higher levels of soluble markers of inflammation (C-reactive protein, soluble CD30). Increased inflammation may be driven by microbiome composition, as shown by a greater abundance of Prevotella and a higher Shannon Diversity Index. In addition, we have observed higher frequency of CD4+CCR5+ target cells and decreased DNA methylation of the CCR5 gene in the gut mucosa of TGW compared with CW and men who have sex with men, which was inversely correlated with testosterone levels. The rectal microbiome composition in TGW appears to favor a proinflammatory milieu as well as mucosal barrier disruption. Thus, it is possible that increased inflammation and higher frequencies of CCR5-expressing target cells at sites of mucosal viral entry may contribute to increased risk of HIV acquisition in TGW, with further validation in larger studies warranted.

HIV/Sexually Transmitted Infection Screening and Eligibility for HIV Preexposure Prophylaxis Among Women Incarcerated in an Urban County Jail.

Incarcerated women experience high rates of HIV and sexually transmitted infections (STIs); few are offered HIV preexposure prophylaxis (PrEP). We aimed to examine HIV/STI screening rates in this population and identify PrEP eligibility. Results of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) urine and HIV/syphilis screening in cisgender women in the Dallas County Jail were compiled from January to October 2020. An electronic health record review was conducted for a subgroup in March 2020 to identify PrEP eligibility. Overall, 4398 of 13,292 women were screened for CT and 4389 of 13,292 for GC, and among them, 479 (11%) screened for HIV and 562 (13%) for syphilis. Furthermore, 462 of 4398 (11%) were positive for CT, 323 of 4389 (7%) were positive for GC, 10 of 479 (2%) had positive HIV test results, of whom 6 (1.3%) were new diagnoses and 75 (13%) had a reactive rapid plasma reagin test. In March 2020, of 541 women screened, 90 tested positive for CT or GC. Of these 90, 70 (78%) did not receive HIV or syphilis screening, including women with these risk factors: 10 (14%) were homeless, 11 (16%) reported heroin use, and 10 (14%) reported methamphetamine use. Based on the presence of an acute bacterial STI, 17% (96 of 541) were PrEP eligible. Incarcerated women had high STI rates and other risk factors for HIV acquisition, although only 1 in 5 with acute STIs (11% overall) was also screened for HIV or syphilis. HIV prevention efforts should include comprehensive STI/HIV screening, linkage to treatment, and identification of PrEP candidates.

Strong Father-Child Relationships and Other Positive Childhood Experiences, Adverse Childhood Experiences, and Sexual Risk Factors for HIV among Young Adults Aged 19-24 Years, Namibia, 2019: A Cross-Sectional Study.

Using cross-sectional data from the 2019 Namibia Violence Against Children and Youth Survey and sex-stratified multivariable models, we assessed the associations between four different positive childhood experiences (PCEs) and having ≥3 adverse childhood experiences (ACEs), including ≥3 ACE-PCE interaction terms, and seven sexual risk factors for HIV acquisition among young adults aged 19-24 years. One PCE, having a strong father-child relationship, was inversely associated with two risk factors among women (lifetime transactional sex (OR, 0.4; 95% CI, 0.2-0.7) and recent age-disparate sexual relationships (OR, 0.3; 95% CI, 0.2-0.5)), and significantly interacted with having ≥3 ACEs for three risk factors among women (not knowing a partner's HIV status, infrequently using condoms, and ever having an STI) and one among men (having multiple sexual partners in the past year). The other PCEs were significantly associated with ≤1 HIV risk factor and had no significant interaction terms. Strong father-child relationships may reduce HIV acquisition risk and mitigate the effect of childhood adversity on HIV risk among young adults in Namibia.

HIV pre-exposure prophylaxis initiation, persistence, and adherence during pregnancy through the postpartum period.

We evaluated pre-exposure prophylaxis (PrEP) initiation, persistence, and adherence measured via tenofovir-diphosphate (TFV-DP) concentrations in dried blood spots (DBS) among women offered PrEP during pregnancy. We prospectively analyzed data from participants in the PrIMA Study (NCT03070600) who were offered PrEP during the second trimester and followed through 9 months postpartum. At follow-up visits (monthly in pregnancy; 6 weeks, 6 months, 9 months postpartum), self-reported PrEP use was assessed, and DBS were collected for quantifying TFV-DP concentrations. In total, 2949 participants were included in the analysis. At enrollment, median age was 24 years [interquartile range IQR) 21-29], gestational age 24 weeks (IQR 20-28), and 4% had a known partner living with HIV. Overall, 405 (14%) participants initiated PrEP in pregnancy with higher frequency among those with risk factors for HIV acquisition, including >2 lifetime sexual partners, syphilis during pregnancy, forced sex, and intimate partner violence ( P < 0.05). At 9 months postpartum, 58% of PrEP initiators persisted with PrEP use, of which 54% self-reported not missing any PrEP pills in the last 30 days. Among DBS randomly selected from visits where participants persisted with PrEP ( n = 427), 50% had quantifiable TFV-DP. Quantifiable TFV-DP was twice as likely in pregnancy than postpartum [adjusted risk ratio (aRR) = 1.90, 95% confidence interval (CI) 1.40-2.57, P < 0.001]. Having a partner known to be living with HIV was the strongest predictor of PrEP initiation, persistence, and quantifiable TFV-DP ( P < 0.001). PrEP persistence and adherence waned postpartum, though over half of PrEP initiators persisted through 9-months postpartum. Interventions should prioritize increasing knowledge of partner HIV status and sustaining adherence in the postpartum period.

Characterizing HIV Syndemics and the Role of Incarceration Among Men Who have Sex with Men Presenting for Care at a Sexually Transmitted Infections Clinic.

Men who have sex with men (MSM) with a history of incarceration experience unique risk factors for HIV acquisition. The current study examined unique risk factors for HIV among MSM with a history of incarceration presenting to a sexually transmitted infections (STI) clinic. We analyzed self-reported behavioral data from clinical encounters among patients attending the clinic between January 2012 and April 2021. There were 17,221 unique visits, of which 5988 were MSM. Of these, 4.34% (N = 206) were MSM with a history of incarceration. MSM with a history of incarceration were significantly more likely to report a range of behavioral risk factors for HIV, yet also were significantly less likely to perceive themselves at risk for HIV. Future research and practice should develop culturally tailored biobehavioral HIV prevention services and consider embedding these programs within criminal justice settings to better reach this at-risk group.

No increased in utero and peripartum HIV acquisition risk in HIV-exposed preterm infants.

Limited data exist on the differential risk of HIV acquisition between infants born preterm versus those born at term to women living with HIV (WLHIV). With a reported increase in preterm delivery among pregnant WLHIV, understanding the risk of vertical transmission of HIV in preterm infants can inform strategies to optimise the timing of diagnostic testing, antiretroviral prophylaxis, and infant feeding. To describe the prevalence and timing of HIV acquisition, in utero versus perinatal, among infants with perinatal HIV exposure born prior to 37 weeks completed gestation age compared to those born at term in the Botswana-based Mpepu study and explore predictors of infant HIV acquisition. Using data extracted from the Mpepu study, we describe the prevalence, timing and risk factors for HIV acquisition in infants born preterm versus those born at term. Fisher exact testing was used to test for differences in prevalence and timing of HIV and a multivariable logistic regression model was used to assess risk factors for infant HIV acquisition. 2866 infants born to WLHIV were included in this secondary analysis. 532 (19%) were born preterm. There was no observed difference in the prevalence of HIV acquisition among infants born preterm versus at term overall (0.8% vs 0.6%, P = 0.54), at birth (0.2% vs 0.3%, P = 1.00) or between 14 and 34 days post-delivery (0.6% vs 0.3%, P = 0.41). The absence of maternal antiretroviral use during pregnancy significantly predicted infant HIV acquisition, with the risk of HIV acquisition reduced by 96% among infants whose mothers were taking antiretroviral treatment (ART) during pregnancy (adjusted odds ratio: 0.003, confidence interval: 0.01-0.02, P < 0.001). There was no observed increase of in utero and peripartum HIV acquisition among infants born preterm following foetal exposure to HIV compared to those born at term.

Factors Associated with Intention to Initiate Pre-exposure Prophylaxis in Cisgender Women at High Behavioral Risk for HIV in Washington, D.C.

Pre-exposure prophylaxis (PrEP) for HIV prevention is underutilized by cisgender women at risk for HIV in the USA. Published research on PrEP initiation among cisgender women at risk for HIV focuses on identifying barriers and facilitators associated with intention to initiate, but few apply a behavioral theoretical lens to understand the relative importance of these diverse factors. This study provides a theoretically grounded view of the relative importance of factors associated with intention to initiate PrEP. We conducted an anonymous, cross-sectional survey of 1437 cisgender women seeking care at family planning and sexual health clinics to evaluate hypothesized barriers and facilitators of PrEP initiation. We categorized cisgender women with ≥ 3 behavioral risk-factors as "high-risk" for HIV acquisition; 26.9% (N = 387) met high-risk criterion. Among cisgender women in the high-risk sample, the majority were Black and single. Perceived risk of HIV acquisition was low and 13.7% reported intention to initiate PrEP. Positive attitudes toward PrEP, self-efficacy, perceived support from medical providers and social networks, and prior discussion about PrEP with medical providers were associated with intention to initiate PrEP; stigma was negatively associated. Background characteristics (other than age), risk factors for HIV acquisition, prior awareness of PrEP, and perceived risk of HIV were not associated with uptake intention. These findings support interventions that center on the role of providers in the provision of PrEP and on social networks in destigmatization of PrEP use.

Women Trust Their OBGYNs to Provide Preexposure Prophylaxis: An Opportunity for HIV Prevention.

ObjectiveThe objective of this study was to understand how women perceive the role of their Obstetrician and Gynecologist (OBGYN) in screening for and providing preexposure prophylaxis (PrEP) for HIV prevention.MethodsWe recruited women ages 18–45 years receiving obstetric or gynecological care at an academic medical center in the Bronx, NY. Thirty participants were enrolled: 10 seeking care for family planning, 10 seeking prenatal care, and 10 seeking care for a sexually transmitted infection. We screened participants for HIV acquisition risk using a PrEP screening tool. We conducted face-to-face, semi-structured interviews, which were audio-recorded, transcribed, and entered into Dedoose for analysis of themes using a grounded theory approach.ResultsSixty percent of the participants were Latinx and 33% African American. Seventy percent had one or more risk factors for HIV acquisition based on the PrEP screening tool, indicating they would benefit from a PrEP discussion. Three main themes emerged from the analysis of interview data. Participants viewed OBGYNs as experts in sexual and reproductive healthcare and believed they were experts in PrEP. Participants were concerned about “PrEP stigma”, being judged by their clinicians as being sexually promiscuous if they expressed a need for PrEP. Lastly, when participants trusted their OBGYN, that trust became a facilitator for women to consider PrEP and offset stigma as a barrier to identifying patients who are candidates for PrEP.ConclusionWomen established in care with an OBGYN are enthusiastic about having access to PrEP services incorporated into their sexual and reproductive healthcare. A universal approach to HIV prevention would avert stigma surrounding HIV care and prevention.

Evolving epidemiology of HIV/AIDS in Campania region, 2011-2018: Is HIV/AIDS population in Campania different?

Objectives:Data on HIV/AIDS cases in Italy are collected using a standardised form. Regional epidemiology may vary. We described the epidemiological and clinical characteristics of newly diagnosed persons with HIV in the ‘Cotugno’ hospital in Naples during 2011–2018 and compared them with national data to identify similarities and differences.Methods:Data source for the Campania region is the data collection forms sent to the national surveillance system. The data source for the national data is from the periodic annual bulletins on HIV/AIDS published by the National Institute of Health.Results:In all, 1149 persons with HIV were diagnosed in ‘Cotugno’ (69.7% of those diagnosed in Campania). Persons with HIV in Campania showed many similarities with the Italian population: men were in the majority in both groups (about 75%), foreign origin was about 30%, heterosexuals were the most represented risk group, followed by men who have sex with men and injecting drug use in both samples. Some notable differences are also present. Among the risk factors for HIV acquisition, injecting drug use is significantly more common in Campania. Among the reasons for testing, significant differences are evident for almost all reasons, with screening activities (testing for concurrent diseases, for diagnosis of sexually transmitted diseases, screening in hospital during maternity care and screening in drug-addition services or prisons) being more common at the national level. The Campania population has a more severe disease pattern, with a significantly higher proportion of patients diagnosed with less than 200 CD4 cells/µL and AIDS. For each variable, we compared trends in the Campania region and in Italy using Spearman’s correlation coefficient. Almost all trends show a weak correlation.Conclusion:In conclusion, the prevalence of injecting drug use is still consistent, and requires specific campaigns. The reasons for testing are different: screening activities work less in Campania than in Italy. This untimely approach contributes to a more severe clinical picture in Campania.

Bringing social context into global biomedical HIV cure-related research: An urgent call to action

Advances in science have ushered in a wave of new potential curative and control strategies for HIV that could eliminate the current requirement for life-long antiretroviral therapy (ART) for people living with HIV (PLWH). In this article, we argue that it is critical to consider social contexts in the development of HIV cure trial protocols. The biological and behavioral risk factors for HIV acquisition by study participants are inseparable from the social context in which these participants live. The article discusses an example of a cohort established to further HIV cure research that included social context, called the FRESH Acute HIV study, which combines a sociostructural intervention while conducting HIV prevention, treatment and cure-related research in Durban, South Africa. We make an urgent call to action to include sociobehavioral components as instrumental in future HIV cure trials in global context.

862. A Survey of HIV PrEP Prescribing Practices at an Academic Medical Center in the Northwest United States

Abstract Background The prescribing of pre-exposure prophylaxis (PrEP) remains a major means of reducing the incidence of HIV infection in the United States. Many individuals are unaware of their HIV status until further symptom progression has ensued or continue to engage in high-risk behavior despite awareness of the risk of HIV transmission. Primary care providers are instrumental in identifying patients who are at high risk of HIV acquisition and prescribing PrEP with appropriate counseling and monitoring. Methods In order to identify existing barriers to prescribing HIV PrEP at a single academic medical center, a voluntary 14-question de-identified survey was administered electronically to ambulatory care providers in the following departments: family medicine, internal medicine and geriatrics, adolescent and young adult health, student health, and women’s health clinics. Results Following survey dissemination, the response rate was 28% (82/286). The results are displayed in Tables 1-3. Notably, though 74% of survey respondents reported being familiar with CDC 2017 and USTPF 2019 clinical practice guidelines for PrEP prescribing, only 36% (22/61) were able to correctly identify the clinical scenarios in the survey whereby an individual is eligible for HIV PrEP. 57% (47/82) reported that they discuss HIV PrEP with less than 25% of eligible patients. Conclusion A significant proportion of healthcare providers at a major regional academic medical center are either not familiar with HIV PrEP prescribing clinical practice guidelines or are unable to appropriately identify situations whereby an individual meets eligibility for PrEP. In addition, a significant proportion do not discuss HIV PrEP with eligible patients. As such, data from the conducted survey will be used to inform the creation of clinical decision support tool to identify risk factors for HIV acquisition in patients, educate providers on guideline-based indications, and provide the option of a telePrEP referral service. Downstream effects anticipated from this intervention include increased HIV/STI testing, case identification, and increased rates of PrEP counseling and prescribing.

Changes in prevalence of violence and risk factors for violence and HIV among children and young people in Kenya: a comparison of the 2010 and 2019 Kenya Violence Against Children and Youth Surveys

Previous research has shown a high prevalence of violence among young people in Kenya. Violence is a known risk factor for HIV acquisition and these two public health issues could be viewed as a syndemic. In 2010, Kenya became the third country to implement the Violence Against Children and Youth Survey (VACS). The study found a high prevalence of violence in the country. Led by the Government of Kenya, stakeholders implemented several prevention and response strategies to reduce violence. In 2019, Kenya implemented a second VACS. This study examines the changes in violence and risk factors for violence and HIV between 2010 and 2019. The 2010 and 2019 VACS used a similar sampling approach and measures. Both VACS were cross-sectional national household surveys of young people aged 13-24 years, designed to produce national estimates of physical, sexual, and emotional violence. Prevalence and changes in lifetime experiences of violence and risk factors for violence and HIV were estimated. The VACS uses a three-stage cluster sampling approach with random selection of enumeration areas as the first stage, households as the second stage, and an eligible participant from the selected household as the third stage. The VACS questionnaire contains sections on demographics, risk and protective factors, violence victimisation, violence perpetration, sexual behaviour, HIV testing and services, violence service knowledge and uptake, and health outcomes. For this study, the main outcome variables were violence victimisation, context of violence, and risk factors for violence. All analyses were done with the entire sample of 13-24-year-olds stratified by sex and survey year. The prevalence of lifetime sexual, physical, and emotional violence significantly declined in 2019 compared with 2010, including unwanted sexual touching, for both females and males. Experience of pressured and forced sex among females also decreased between the surveys. Additionally, significantly more females sought and received services for sexual violence and significantly more males knew of a place to seek help in 2019 than in 2010. The prevalence of several risk factors for violence and HIV also declined, including infrequent condom use, endorsement of inequitable gender norms, endorsement of norms justifying wife beating, and never testing for HIV. Kenya observed significant declines in the prevalence of lifetime violence and some risk factors for violence and HIV, and improvements in some service seeking indicators between 2010 and 2019. Continued prioritisation of preventing and responding to violence in Kenya could contribute to further reductions in violence and its negative outcomes. Other countries in the region that have made substantial investments and implemented similar violence prevention programmes could use repeat VACS data to monitor violence and related outcomes over time. None.

Factors associated with HIV infection among children in Larkana District, Pakistan: a matched case-control study

In April, 2019, an HIV outbreak predominantly affecting children occurred in Larkana District, Sindh, Pakistan. By December, 2019, 881 (4·0%) of 21 962 children screened for HIV had tested positive. We aimed to assess factors associated with HIV infection in this outbreak. In this individually matched case-control study, we sampled 406 cases (individuals aged <16 years who had registered for paediatric HIV care at the HIV Treatment Centre at Shaikh Zayed Children's Hospital in Larkana City, Pakistan) and 406 controls (individuals without HIV matched by age, sex, and neighbourhood residence, recruited through doorknocking at houses adjacent to case participants). An interviewer-administered questionnaire was used to collect data on possible risk factors for HIV acquisition and a blood sample was collected from all participants for hepatitis B and hepatitis C serology. Mothers of all participants underwent HIV testing. Odds ratios were estimated using conditional logistic regression to assess factors associated with HIV infection. 406 case-control pairs were recruited between July 3 and Dec 26, 2019. Five pairs were excluded (three pairs had an age mismatch and two pairs were duplicate cases) and 401 were analysed. The prevalence of hepatitis B surface antigen was 18·2% (95% CI 14·5-22·3) among cases and 5·2% (3·3-7·9) among controls, and the prevalence of hepatitis C antibodies was 6·5% (95% CI 4·3-9·4) among cases and 1·0% (0·3-2·5) among controls. 28 (7%) of 397 mothers of cases for whom we had data, and no mothers of 394 controls, were HIV positive. In the 6 months before recruitment, 226 (56%) of 401 cases and 32 (8%) of 401 controls reported having more than ten injections, and 291 (73%) cases and 78 (19%) controls had received an intravenous infusion. At least one blood transfusion was reported in 56 (14%) cases and three (1%) controls in the past 2 years. HIV infection was associated with a history of more injections and infusions (adjusted odds ratio 1·63; 95% CI 1·30-2·04, p<0·0001), blood transfusion (336·75; 23·69-4787·01, p<0·0001), surgery (399·75, 13·99-11 419·39, p=0·0005), the child's mother being HIV positive or having died (3·13, 1·20-8·20, p=0·020), and increased frequency of private clinic (p<0·0001) and government hospital visits (p<0·0001), adjusting for confounders. The predominant mode of HIV transmission in this outbreak was parenteral, probably due to unsafe injection practices and poor blood safety practices. General practitioners across Pakistan need training and systems support in reducing injection use, and in providing safe injections and transfusions only when necessary.

Correlates of Self-Reported HIV Testing Among Patients in Specialized Substance Abuse Treatment Centers in South Africa.

Substance use is a recognized risk factor for HIV acquisition, transmission and progression in South Africa. Persons who use drugs (PWUD) and access specialist substance abuse treatmentcenters (SSATCs)are a potentially critical target group for HIV services because of the severity of their substance use and associated health risks. SSATCsrepresent an opportunity for integrated programming, particularly HIV testing services (HTS), to reach PWUD who are at an increased risk of or living with HIV. This analysis of national SSATC admission dataexploresself-reported HIV testing and associated factors to identify coverage gaps and integration opportunities. The South African Community Epidemiology Network on Drug Use (SACENDU) collects routine surveillance data to monitor national treatment admission trends in alcohol andother drug use. SACENDU data from 2012 to 2017 was analyzed usingchi-square test of independence and logistic regression to examine associations betweenHTS, demographic characteristics and substances of use. Of 87,339 treatment admissions,47.5% (n = 41,481) of patients had not accessedHTSin the prior 12months.HTS was reported less frequently by patients whose primary substance of use was cannabis or those with polysubstance use (36.9% and 41.1%, respectively).None of the substance use sub-groupsreported a testing rate above 70%.Compared to specific reference groups, logistic regression showed those with lower odds of HTS were:15-19years (OR = 0.59); had primary-level education (OR = 0.51); were scholars/learners (OR = 0.27); andprimarily cannabis users (OR = 0.64). Patients whose primary drug was heroin had higher odds of testing (OR = 2.45) as did those who injected drugs (OR = 2.86). Given the low coverage and decreased odds of self-reportedHTSamong sub-groups of patients inSSATCs, the integration of HIV services for PWUD should be a priority inSouth Africa and a focus of the national HIV strategy.

Common mental disorders and HIV status in the context of DREAMS among adolescent girls and young women in rural KwaZulu-Natal, South Africa

BackgroundHIV affects many adolescent girls and young women (AGYW) in South Africa. Given the bi-directional HIV and mental health relationship, mental health services may help prevent and treat HIV in this population. We therefore examined the association between common mental disorders (CMD) and HIV-related behaviours and service utilisation, in the context of implementation of the combination DREAMS (Determined, Resilient, Empowered, AIDS-free, Mentored and Safe) HIV prevention programme in rural uMkhanyakude district, KwaZulu-Natal. DREAMS involved delivering a package of multiple interventions in a single area to address multiple sources of HIV risk for AGYW.MethodsWe analysed baseline data from an age-stratified, representative cohort of 13–22 year-old AGYW. We measured DREAMS uptake as a count of the number of individual-level or community-based interventions each participant received in the last 12 months. CMD was measured using the validated Shona Symptom Questionnaire, with a cut off score ≥ 9 indicating probable CMD. HIV status was ascertained through home-based serotesting. We used logistic regression to estimate the association between CMD and HIV status adjusting for socio-demographics and behaviours.ResultsProbable CMD prevalence among the 2184 respondents was 22.2%, increasing steadily from 10.1% among 13 year-old girls to 33.1% among 22 year-old women. AGYW were more likely to report probable CMD if they tested positive for HIV (odds ratio vs. test negative: 1.88, 95% confidence interval: 1.40–2.53). After adjusting for socio-demographics and behaviours, there was evidence that probable CMD was more prevalent among respondents who reported using multiple healthcare-related DREAMS interventions.ConclusionWe found high prevalence of probable CMD among AGYW in rural South Africa, but it was only associated with HIV serostatus when not controlling for HIV acquisition risk factors. Our findings highlight that improving mental health service access for AGYW at high risk for HIV acquisition might protect them. Interventions already reaching AGYW with CMD, such as DREAMS, can be used to deliver mental health services to reduce both CMD and HIV risks. There is a need to integrate mental health education into existing HIV prevention programmes in school and communities.

KAPOSI SARCOMA IN AN IMMUNOSUPPRESSED PATIENT WITH PRESUMED CROHN’S DISEASE: IATROGENIC OR EPIDEMIC?

Abstract Introduction Biologic immunosuppression and HIV infection both carry risks of infection and malignancy. Small series suggest that patients living with well-controlled HIV may safely and efficaciously use biologics, like TNF-alpha inhibitors (TNF-I). However, no current U.S. guidelines exist to screen for HIV infection among high-risk groups prior to starting TNF-I. We describe the case of a patient who received TNF-I for Crohn’s Disease without any HIV testing, who developed potentially avoidable extensive Kaposi Sarcoma. Case Description A healthy 32-year-old man presented with 1 month of diarrhea and a 15-lb weight loss. Fecal calprotectin, ESR, and CRP were markedly elevated. Endoscopy demonstrated severe rectal inflammation with perirectal abscess and perianal skin tags, suggestive of inflammatory bowel disease. Biopsies showed active colitis with ulceration, cryptitis, and fibropurulent debris without evidence of granulomata, dysplasia, or CMV. He was treated with IV antibiotics, IV steroids, and 2 infusions of infliximab at 5 mg/kg. He continued to have 4 loose stools an hour, limiting his steroid wean. One month later, he developed painful, violaceous plaques on his face, buccal mucosa, torso, and lower extremities. Biopsy showed Kaposi Sarcoma, and HIV test was positive, with viral load 3292 and CD4 count 248. Although in a monogamous relationship with his husband, a well-recognized risk factor for HIV acquisition, he had never been tested for HIV. Antiretroviral therapy was initiated promptly. Repeat rectal biopsies stained positive for HHV-8 and CMV, concerning for rectal KS and CMV proctitis. He started valgancyclovir but self-increased prednisone, with poor symptom relief. Review of the initial endoscopy confirmed no obvious HHV-8 positivity. Three weeks after HIV diagnosis, he developed new red nodules across his chest, suspicious for worsening KS due to immune reconstitution inflammatory syndrome (IRIS). He completed 12 cycles of chemotherapy and had no sign of residual IBD on recent colonoscopy. KS is his presumed original diagnosis. Discussion Current U.S. guidelines do not recommend HIV screening prior to TNF-I use, despite the heightened risks of cumulative immune dysregulation. Our patient should have been screened annually for HIV according to CDC guidelines. Further, his uncontrolled HIV infection in combination with TNF-I and high dose steroids led to life-threatening Stage IV malignancy (KS), complicated by immune reconstitution inflammatory syndrome and poor ART absorption. We propose that all patients should be screened for common risk factors for HIV acquisition, such as men who have sex with men or intravenous drug use. For high risk patients, gastroenterologists should consider screening for HIV, in addition to tuberculosis and hepatitis, prior to immunosuppression with TNF-I.

Increase in HIV incidence in women exposed to rape.

Objective:To determine the incidence of HIV acquisition in women postrape compared with a cohort of women who had not been raped.Design:A prospective cohort study.Methods:The Rape Impact Cohort Evaluation study based in Durban, South Africa, enrolled women aged 16–40 years from postrape care services, and a control group of women from Primary Healthcare services. Women who were HIV negative at baseline (441 in the rape-exposed group and 578 in the control group) were followed for 12–36 months with assessments every 3 months in the first year and every 6 months thereafter. Multivariable Cox regression models adjusted for baseline and time varying covariates were used to investigate the effect of rape exposure on HIV incidence over follow-up.Results:Eighty-six women acquired HIV during 1605.5 total person-years of follow-up, with an incident rate of 6.6 per 100 person-years [95% confidence interval (CI): 4.8–9.1] among the rape exposed group and 4.7 per 100 person-years (95% CI: 3.5–6.2) among control group. After controlling for confounders (age, previous trauma, social support, perceived stress, multiple partners and transactional sex with a casual partner), women exposed to rape had a 60% increased risk of acquiring HIV [adjusted hazard ratio: 1.59 (95% CI: 1.01–2.48)] compared with those not exposed. Survival analysis showed difference in HIV incident occurred after month 9.Conclusion:Rape is a long-term risk factor for HIV acquisition. Rape survivors need both immediate and long-term HIV prevention and care.

Microbial function and genital inflammation in young South African women at high risk of HIV infection

BackgroundFemale genital tract (FGT) inflammation is an important risk factor for HIV acquisition. The FGT microbiome is closely associated with inflammatory profile; however, the relative importance of microbial activities has not been established. Since proteins are key elements representing actual microbial functions, this study utilized metaproteomics to evaluate the relationship between FGT microbial function and inflammation in 113 young and adolescent South African women at high risk of HIV infection. Women were grouped as having low, medium, or high FGT inflammation by K-means clustering according to pro-inflammatory cytokine concentrations.ResultsA total of 3186 microbial and human proteins were identified in lateral vaginal wall swabs using liquid chromatography-tandem mass spectrometry, while 94 microbial taxa were included in the taxonomic analysis. Both metaproteomics and 16S rRNA gene sequencing analyses showed increased non-optimal bacteria and decreased lactobacilli in women with FGT inflammatory profiles. However, differences in the predicted relative abundance of most bacteria were observed between 16S rRNA gene sequencing and metaproteomics analyses. Bacterial protein functional annotations (gene ontology) predicted inflammatory cytokine profiles more accurately than bacterial relative abundance determined by 16S rRNA gene sequence analysis, as well as functional predictions based on 16S rRNA gene sequence data (p < 0.0001). The majority of microbial biological processes were underrepresented in women with high inflammation compared to those with low inflammation, including a Lactobacillus-associated signature of reduced cell wall organization and peptidoglycan biosynthesis. This signature remained associated with high FGT inflammation in a subset of 74 women 9 weeks later, was upheld after adjusting for Lactobacillus relative abundance, and was associated with in vitro inflammatory cytokine responses to Lactobacillus isolates from the same women. Reduced cell wall organization and peptidoglycan biosynthesis were also associated with high FGT inflammation in an independent sample of ten women.ConclusionsBoth the presence of specific microbial taxa in the FGT and their properties and activities are critical determinants of FGT inflammation. Our findings support those of previous studies suggesting that peptidoglycan is directly immunosuppressive, and identify a possible avenue for biotherapeutic development to reduce inflammation in the FGT. To facilitate further investigations of microbial activities, we have developed the FGT-DB application that is available at http://fgtdb.org/.DwvYvmP_Lqo1TfCUgVQTWuVideo
