Covid-19 vaccine immunogenicity in people living with HIV-1

IntroductionCOVID-19 vaccine efficacy has been evaluated in large clinical trials and in real-world situation. Although they have proven to be very effective in the general population, little is known about their efficacy in immunocompromised patients. HIV-infected individuals’ response to vaccine may vary according to the type of vaccine and their level of immunosuppression. We evaluated immunogenicity of an mRNA anti-SARS CoV-2 vaccine in HIV-positive individuals. MethodsHIV-positive individuals (n = 121) were recruited from HIV clinics in Montreal and stratified according to their CD4 counts. A control group of 20 health care workers naïve to SARS CoV-2 was used. The participants’ Anti-RBD IgG responses were measured by ELISA at baseline and 3–4 weeks after receiving the first dose of an mRNA vaccine). ResultsEleven of 121 participants had anti-COVID-19 antibodies at baseline, and a further 4 had incomplete data for the analysis. Mean anti-RBD IgG responses were similar between the HIV negative control group (n = 20) and the combined HIV+ group (n = 106) (p = 0.72). However, these responses were significantly lower in the group with <250 CD4 cells/mm3. (p < 0.0001). Increasing age was independently associated with decreased immunogenicity. ConclusionHIV-positive individuals with CD4 counts over 250 cells/mm3 have an anti-RBD IgG response similar to the general population. However, HIV-positive individuals with the lowest CD4 counts (<250 cells/mm3) have a weaker response. These data would support the hypothesis that a booster dose might be needed in this subgroup of HIV-positive individuals, depending on their response to the second dose.

Heightened levels of plasma growth differentiation factor 15 in men living with HIV.

Plasma biomarkers that reflect energy balance disorders in people living with HIV (PLWH) remain limited. Growth differentiation factor 15 (GDF15) abundance in plasma of mice and humans induces negative energy balance but also becomes highly elevated in obesity and other metabolic diseases. We sought to compare plasma GDF15 levels in PLWH and HIV‐negative persons and mouse models expressing the HIV accessory protein Vpr (that recapitulate HIV‐associated metabolic disorders) and determine their relationship to metabolic parameters. We measured liver Gdf15 mRNA levels and plasma GDF15 levels in male Vpr mice and littermate controls. In parallel, we analyzed plasma GDF15 levels in 18 male PLWH on stable, long‐term antiretroviral therapy and 13 HIV‐negative men (6 healthy controls and 7 with metabolic syndrome). Plasma GDF15 levels were correlated with anthropometric and immune cell parameters in humans. Gene expression analysis of Vpr mouse liver demonstrated elevated Gdf15 mRNA. Plasma GDF15 levels were also higher in Vpr mouse models. Levels of plasma GDF15 in PLWH were greater than in both HIV‐negative groups and correlated positively with the CD4/CD8 T cell ratio in PLWH. Plasma GDF15 levels correlated positively with age in the HIV‐negative subjects but not in PLWH. Since GDF15 levels predict fatty liver disease and energy balance disorders, further studies are warranted to determine the effect of GDF15 in mediating the metabolic disturbances that occur in Vpr mice and PLWH.

Risk of SARS-CoV-2 Infection Among People Living With HIV in Wuhan, China.

BackgroundIn the era of the COVID-19 pandemic, people living with HIV (PLWH) face more challenges. However, it is unclear if PLWH is more susceptible to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection than HIV-negative individuals. This study aimed to explore the prevalence of the SARS-CoV-2 infection and the associated risk factors among PLWH.MethodsFrom 1 to 30 May 2020, we conducted a cross-sectional survey that enrolled 857 PLWH and 1,048 HIV-negative individuals from the Wuchang district in Wuhan, China. Our data analysis compared the rate of the SARS-CoV-2 infection among PLWH and HIV-negative participants, and the proportions of symptomatic patients and asymptomatic infectors between the two groups. We also assessed the risk factors associated with the SARS-CoV-2 infection among PLWH.ResultsOverall, 14/857 (1.6%) PLWH and 68/1,048 (6.5%) HIV-negative participants were infected with SARS-CoV-2. Among the SARS-CoV-2-infected PLWH participants, 6/14 (42.8%) were symptomatic patients, 4/14 (28.6%) were SARS-CoV-2 nucleic acid-positive asymptomatic infectors, and 4/14 (28.6%) were serology-positive asymptomatic infectors. Among the infected HIV-negative participants, 5/68 (7.4%) patients were symptomatic and 63/68 (92.6%) were serology-positive asymptomatic infectors. The rate of the SARS-CoV-2 infection was lower among the PLWH than in the HIV-negative group (1.96% vs. 5.74%, p = 0.001) and the rate of morbidity among the symptomatic patients was similar between the two groups (p = 0.107). However, there were more serology-positive asymptomatic infectors among the infected HIV-negative participants than among the infected PLWH (0.54% vs. 5.46%, p = 0.001). Furthermore, being 50 years or older (aOR = 4.50, 95% CI: 1.34–15.13, p = 0.015) and having opportunistic infections (aOR = 9.59, 95% CI: 1.54–59.92, p = 0.016) were associated with an increased risk of SARS-CoV-2 infection among PLWH.ConclusionsPLWH has more varied forms of the SARS-CoV-2 infection than the HIV-negative population and should, therefore, undertake routine screening to avoid late diagnosis. Also, older age (≥50 years) and having opportunistic infections increase the risks of SARS-CoV-2 infection among PLWH.

Increased biomarkers of cardiovascular risk in HIV-1 viremic controllers and low persistent inflammation in elite controllers and art-suppressed individuals

HIV controllers (HICs) are models of HIV functional cure, although some studies have shown persistent inflammation and increased rates of atherosclerosis in HICs. Since immune activation/inflammation contributes to the pathogenesis of cardiovascular diseases (CVD), we evaluated clinical data and inflammation markers in HIV-1 viremic controllers (VC), elite controllers (EC), and control groups (HIV positive individuals with virological suppression by antiretroviral therapy—cART; HIV negative individuals—HIVneg) to assess whether they presented elevated levels of inflammation markers also associated with CVD. We observed the highest frequencies of activated CD8+ T cells in VCs, while EC and cART groups presented similar but slightly altered frequencies of this marker when compared to the HIVneg group. Regarding platelet activation, both HICs groups presented higher expression of P-selectin in platelets when compared to control groups. Monocyte subset analyses revealed lower frequencies of classical monocytes and increased frequencies of non-classical and intermediate monocytes among cART individuals and in EC when compared to HIV negative individuals, but none of the differences were significant. For VC, however, significant decreases in frequencies of classical monocytes and increases in the frequency of intermediate monocytes were observed in comparison to HIV negative individuals. The frequency of monocytes expressing tissue factor was similar among the groups on all subsets. In terms of plasma markers, VC had higher levels of many inflammatory markers, while EC had higher levels of VCAM-1 and ICAM-1 compared to control groups. Our data showed that VCs display increased levels of inflammation markers that have been associated with CVD risk. Meanwhile, ECs show signals of lower but persistent inflammation, comparable to the cART group, indicating the potential benefits of alternative therapies to decrease inflammation in this group.

Macular Changes Observed on Optical Coherence Tomography Angiography in Patients Infected With Human Immunodeficiency Virus Without Infectious Retinopathy.

PurposeAs the human immunodeficiency virus (HIV) pandemic is far from over, whether there are subclinical macular changes in HIV-positive patients is something that should not be overlooked. We aimed to apply optical coherence tomography angiography (OCTA) to assess the macular structure and microvasculature changes in patients with HIV without infectious retinopathy.MethodsHIV-positive and -negative participants were included and classified into three groups: HIV-negative, HIV-positive, and HIV-positive with microvasculopathy. OCTA parameters regarding macular structure and microvasculature were analyzed.ResultsCompared with the HIV-negative group, the superficial retinal vessel density (VD) in the parafovea sectors and the whole Early Treatment of Diabetic Retinopathy Study (ETDRS) grid and the choroidal vascularity index (CVI) in the whole ETDRS grid were significantly decreased in the HIV-positive and HIV-positive with microvasculopathy groups (p < 0.05). No differences were found in OCTA parameters between the HIV-positive and HIV-positive with microvasculopathy groups. Retinal, retinal nerve fiber layer-ganglion cell layer-inner plexiform layer (RNFL-GCL-IPL), RNFL, GCL-IPL, and INL thickness showed a negative association with the duration of HIV diagnosis or antiretroviral therapy (ART) (all p < 0.05). All OCTA microvasculature parameters showed no association with HIV-related clinical variables (all p > 0.05).ConclusionsSubclinical macular changes existed in HIV-infected patients without clinical infectious retinopathy. Substructures from inner retinal layers might be associated with HIV infection or ART duration.

Comparison of Anxiety and Depression Among HIV-Positive and HIV-Negative Pregnant Women During COVID-19 Pandemic in Ekiti State, Southwest Nigeria.

PurposeCoronavirus disease 2019 (COVID-19) pandemic is the significant public health crisis of the 21st century that has disrupted personal, local, and international territorial relationships. Earlier studies have shown that people with HIV were at least twice at risk of dying from COVID-19 than the general population. There are also deep concerns about the indirect impact of COVID-19 on women within the reproductive age group in Sub-Saharan Africa who were already struggling to access reproductive healthcare services. In addition, pregnant HIV-positive women have an increased rate of anxiety and depression. This study, therefore, examined depression and anxiety disorders in pregnant HIV-positive women in response to the COVID-19 pandemic.Patients and MethodsThis cross-sectional study used a structured questionnaire containing sociodemographic information, Patient Health Questionnaire-9 (PHQ-9), and General Anxiety Disorder-7 (GAD-7) assessment tools. Data obtained were analyzed using Statistical Package for Social Science version 26.ResultsNinety-nine (99) representing 78% of 127 pregnant HIV-positive women enrolled in the PMTCT program were eligible for this study. This number matched 99 randomly selected pregnant HIV-negative in the study areas as controls. Major depressive disorder (MDD) and severe anxiety disorder were significantly higher among the HIV-positive group than in the HIV-negative group (PHQ-9 Mean ± SD 8.0 ± 5.4 vs 2.3 ± 2.9; p = 0.000) and (GAD-7 Mean ± SD 5.9 ± 4.6 vs 1.2 ± 2.2; p = 0.000).ConclusionGiven the high prevalence of major depressive disorder and severe anxiety disorder among pregnant HIV-positive women, mental health care should be incorporated into the prevention with positive interventions and strategies to reduce the indirect consequences of the COVID-19 pandemic.

Arterial Stiffness in a Cohort of Young People Living With Perinatal HIV and HIV Negative Young People in England

BackgroundAntiretroviral therapy (ART) has increased life expectancy and consequently the risk of cardiovascular disease (CVD) in adults living with HIV. We investigated the levels and predictors of arterial stiffness in young people (YP) living with perinatal HIV (PHIV) and HIV negative YP in the Adolescents and Adults Living with Perinatal HIV (AALPHI) study.MethodsAALPHI was a prospective study evaluating the impact of HIV infection and exposure to ART on YP living with PHIV (aged 13–21 years) who had known their HIV status for at least 6 months, and HIV negative YP (aged 13–23 years) who either had a sibling, friend or parent living with HIV. Participants were enrolled from HIV clinics and community services in England. Two hundred and thirteen PHIV and 65 HIV negative YP (42% siblings of PHIV) had pulse wave velocity (PWV) measurements taken (Vicorder software) from the supra-sternal notch to the middle of the thigh cuff, at their second interview in the study between 2015 and 2017. Average PWV was calculated from the three closest readings (≥3 and ≤ 12 m/s) within 0.6 m/s of each other. Linear regression examined predictors of higher (worse) PWV, including age, sex, HIV status and height as a priori, ethnicity, born outside UK/Ireland, alcohol/nicotine/drug use, weight, waist-to-hip-ratio, mean arterial pressure (MAP), caffeine 2 h before PWV and nicotine on day of PWV. A separate PHIV model included CD4, viral load, years taking ART and ART regimen.FindingsOne hundred and twenty eight (60%) PHIV and 45 (69%) HIV negative YP were female (p = 0.18), with median (IQR) age 18 (16, 20) and 18 (16, 21) years (p = 0.48) respectively. Most PHIV were taking a combination of three ART drugs from two classes. There was a trend toward higher (worse) mean PWV in the PHIV group than the HIV negative group [unvariable analysis 6.15 (SD 0.83) m/s vs. 5.93 (0.70) m/s, respectively, unadjusted p = 0.058], which was statistically significant in the multivariable analysis [adjusted p (ap) = 0.020]. In multivariable analysis being male (ap = 0.002), older age (ap < 0.001), higher MAP (ap < 0.001) and nicotine use on day of measurement (ap = 0.001) were also predictors of higher PWV. The predictors were the same in the PHIV model.InterpretationBy late adolescence PHIV had worse PWV in comparison to HIV negative peers, and traditional risk factors for CVD (higher arterial pressure, being male and older age) were associated with higher PWV values. Regular detailed monitoring of cardiovascular risk factors should become standard of care for every young person with PHIV worldwide.

Increased risk of mental illness in people with HIV.

People with HIV who are diagnosed promptly and treated can now anticipate a life expectancy similar to that of people without HIV.1 However, despite this remarkable narrowing of the gap in mortality risk, a stark disparity in mental health, evident in the early days of the epidemic,2 appears to persist. Studies across a range of countries and settings, using various measurement tools, have consistently found a high burden of depressive symptoms among people with HIV,3 with some reporting a two times higher prevalence compared with the general population or HIV-negative control groups.

A cohort analysis of sexually transmitted infections among different groups of men who have sex with men in the early era of HIV pre-exposure prophylaxis in France

BackgroundMSM are at particular risk of STIs due to sexual behavior and substance use. HIV PrEP use may increase this risk. DesignOur aim was to comparatively assess incident STIs among different at-risk groups—PLWHIV, HIV-negative PrEP and no-PrEP users—seen at our center early after PrEP implementation. MethodsClinical data were retrospectively collected on 636 MSM seen at the Infectious Diseases Department between September 2016 and October 2018. STI incidence rate was assessed among groups for the whole period, as well as separately for each year of the study. ResultsOverall STI incidence rate ratio was higher in HIV-neg when compared to PLWHIV. In multivariate analysis, STI risk was significantly higher among HIV-neg no-PrEP users compared to PLWHIV, while not different between PLWHIV and PrEP users.STI incidence globally increased during the first 2 years after PrEP approval among PLWHIV and no-PrEP users, stated by odds ratio (OR = 1.77 [1.23–2.55], p = 0.0020 and OR = 2.29 [0.91–5.73], p = 0.0774 respectively) while it remained rather stable for HIV-neg PrEP users (OR = 1.19 [0.60–2.38], p = 0.6181). The HIV-neg no-PrEP group remained at higher risk of STI than PLWHIV and PrEP users during the two periods. ConclusionThese results suggest that a proactive approach of an efficient follow-up of MSM participants since PrEP approval may have prevented an increase of the incidence of STIs among PrEP users.

Erythropoietin and iron for anemia in HIV-infected patients undergoing maintenance hemodialysis in China: a cross-sectional study

BackgroundAnemia is a common complication of chronic kidney disease (CKD) and HIV infection. The number of people living with HIV on hemodialysis (HD) is increasing. However, there is no data about anemia and related therapies in this kind of patients in China. We aim to assess the difference in hemoglobin (Hgb) and treatments like erythropoietin and iron between HIV-HD patients and HD patients in Chengdu, China.MethodsThis cross-sectional study was conducted with data collection from January 2020 to June 2020. Thirty-four HIV-infected HD patients and thirty-five non-HIV-infected HD patients were included. Age, gender, dialysis vintage, single-pool (sp) Kt/V, Hgb, the dose of erythropoietin, ferritin, use of iron preparations, and serum albumin were collected in all patients. Time since HIV diagnosis, counts of CD4 + T cells, HIV RNA, and antiretroviral therapy for HIV infection were collected in HIV-infected patients. T-test, Mann–Whitney U test, and chi-square statistics were applied in SPSS.ResultsThe Hgb of HIV-HD and HD groups were 105.70 (95.93–112.08) g/L and 112.00 (93.00–126.00) g/L respectively (P = 0.064). There was a statistically significant higher erythropoietin dosage used in the HIV-HD population (222.55 ± 115.47 U/kg/week) compared to the HIV-negative HD group (161.86 ± 110.31 U/kg/week) (P = 0.029). 16/34 (47.06%) HIV-HD patients and 5/35 (14.29%) HD patients were treated with iron preparations (P = 0.003). The ferritin levels were 316.50 (117.38–589.75) ng/ml and 272.70 (205.00–434.00) ng/ml in HIV-HD and HD groups respectively.ConclusionsA higher erythropoietin dosage and a higher probability of iron preparations may be required to maintain Hgb in HIV-HD patients compared with HD patients.

Behavioral Efficacy of a Sexual Health Mobile App for Men Who Have Sex With Men: Randomized Controlled Trial of Mobile Messaging for Men.

BackgroundGay, bisexual, and other men who have sex with men (GBMSM) face the highest burden of HIV in the United States, and there is a paucity of efficacious mobile health (mHealth) HIV prevention and care interventions tailored specifically for GBMSM. We tested a mobile app combining prevention messages and access to core prevention services for GBMSM.ObjectiveThis study aims to measure the efficacy of the Mobile Messaging for Men (M-cubed) app and related services to increase HIV prevention and care behaviors in diverse US GBMSM.MethodsWe conducted a randomized open-label study with a waitlist control group among GBMSM in 3 groups (low-risk HIV-negative group, high-risk HIV-negative group, and living-with-HIV [LWH] group) recruited online and in venues in Atlanta, Detroit, and New York City. Participants were randomly assigned to receive access to the app immediately or at 9 months after randomization. The app provided prevention messages in 6 domains of sexual health and offered ordering of at-home HIV and sexually transmitted infection test kits, receiving preexposure prophylaxis (PrEP) evaluations and navigation, and service locators. Serostatus- and risk-specific prevention outcomes were evaluated at baseline, at the end of the intervention period, and at 3, 6, and 9 months after the intervention period.ResultsIn total, 1226 GBMSM were enrolled and randomized; of these 611 (49.84%) were assigned to the intervention group and 608 (99.51%) were analyzed, while 615 (50.16%) were assigned to the control group and 612 (99.51%) were analyzed. For high-risk GBMSM, allocation to the intervention arm was associated with higher odds of HIV testing during the intervention period (adjusted odds ratio [aOR] 2.02, 95% CI 1.11-3.66) and with higher odds of using PrEP in the 3 months after the intervention period (aOR 2.41, 95% CI 1.00-5.76, P<.05). No changes in HIV prevention or care were associated with allocation to the intervention arm for the low-risk HIV-negative and LWH groups.ConclusionsAccess to the M-cubed app was associated with increased HIV testing and PrEP use among high-risk HIV-negative GBMSM in 3 US cities. The app could be made available through funded HIV prevention providers; additional efforts are needed to understand optimal strategies to implement the app outside of the research setting.Trial RegistrationClinicalTrials.gov NCT03666247; https://clinicaltrials.gov/ct2/show/NCT03666247International Registered Report Identifier (IRRID)RR2-10.2196/16439

POS-625 ERYTHROPOIETIN AND IRON FOR ANEMIA IN HIV-INFECTED PATIENTS UNDERGOING MAINTENANCE HEMODIALYSIS IN CHINA

A higher erythropoietin dosage and a higher probability of iron preparations may be required to maintain Hgb in HIV-HD patients compared with HD patients.

PROFILAKSIS PRA-PAJANAN (PPrP) HIV/AIDS PADA LELAKI SEKS LELAKI

Introduction: HIV is an infection that attacks the immune system which is characterized by a decrease in CD4+ cells with MSM as the 2nd largest contributor globally. PPrP serves as an additional option in the prevention of HIV-negative MSM from becoming infected with HIV. Objective: This study was conducted to review more deeply the role of pre-exposure prophylaxis in reducing the risk of contracting HIV in male sex groups with HIV negative men and to review the effectiveness and implementation of HIV/AIDS pre-exposure prophylaxis in male sex men so that it is expected to be a consideration in efforts to combat HIV/AIDS. Methods: Literature search was conducted from journal articles published online in the period 2012-2021. The databases used are ScienceDirect, Pubmed, Google Scholar, and Cochrane. Results: The study showed that the factors that significantly affected the high prevalence of HIV cases among MSM were anal sex and based on the findings the use of PrEP showed a significant effectiveness for the MSM group with pre-exposure prophylaxis as a preventive measure in dealing with HIV positive cases. Conclusion: PrEP has been shown to significantly reduce the risk of contracting HIV in HIV-negative MSM groups and has the potential to be an additional prevention option so that it can be applied in efforts to prevent HIV infection and reduce the spread of HIV in MSM.

Fatigue is associated with worse cognitive and everyday functioning in older persons with HIV.

The aim of this study was to determine whether there are relationships between fatigue, cognition, and everyday functioning in older persons with and without HIV and to examine if associations remain after accounting for depression, anxiety, and sleep quality. Sixty-nine persons with HIV (PWH) and 36 persons without HIV, aged 50-74 years, were recruited from ongoing studies at UC San Diego's HIV Neurobehavioral Research Program and from the community. Participants completed neuropsychological testing, a performance-based measure of everyday functioning, and self-report questionnaires of fatigue, depression, anxiety, sleep quality, and everyday functioning. Multivariable linear regressions and logistic regressions stratified by HIV serostatus were used to examine relationships between fatigue, cognition, and everyday functioning. Psychiatric symptoms and sleep quality were examined as covariates. In this cross-sectional study, PWH had significantly greater fatigue than the HIV-negative group (g = 0.83; P < 0.01). When stratifying by HIV serostatus, greater fatigue was significantly associated with worse global cognition (β = -0.56;P < 0.01) in PWH even when controlling for covariates;however, fatigue was not significantly associated with global cognition in persons without HIV. In PWH and when accounting for covariates, fatigue was also associated with greater risk of self-reported everyday functioning impairment [odds ratio (OR) = 1.66 for 10-point increase in fatigue, P = 0.04] but not performance-based everyday functioning (P = 0.95). Fatigue is associated with cognition, particularly measures with a speeded component, and self-reported everyday functioning in older PWH. Findings suggest that fatigue is important to assess and consider in the context of aging with HIV.

The physical sequelae of growing into adolescence with perinatally acquired HIV: a scoping review

Background Adolescents living with perinatal HIV (PHIVA) are a growing population with unique needs. While the impact of HIV on pediatric physical wellbeing is expansively documented, there is only emerging data on the long-term impact of perinatal HIV infection on adolescence and the resultant physical sequelae. Objective This scoping review aimed to identify and describe what is currently known about the physical sequelae that PHIVA face. Method A scoping review was conducted, following the methodology described by the Johanna Briggs Institute manual for Evidence Synthesis. Electronic databases of MEDLINE (PubMed), PEDro, CINAHL (EBSCOhost), Elsevier (Scopus), Elsevier (Science Direct), Google Scholar, CDC Stacks and Open Grey, and reference lists were searched. Two investigators screened the article titles, abstracts and full texts against the inclusion criteria. Data was charted on a data extraction tool, with a descriptive narrative presenting the results. Results Of the 1291 citations screened, eight studies were included. All of the studies were cross-sectional analyses, with only two studies using an HIV-negative comparison group. The studies addressed the physical outcomes of height, weight, body mass index, delayed puberty, physical functioning and activity levels, exercise tolerance and lung function, and pain. These sequelae were categorized into two subgroups: 1) anthropometric characteristics and 2) physical health and functioning. Conclusion The results of this scoping review show that PHIVA face significant physical challenges despite access to antiretroviral therapy. Thus this distinctive population requires unique and specialized healthcare.

Diastolic dysfunction in people with HIV without known cardiovascular risk factors in Western Kenya

ObjectivesDiastolic dysfunction (DD) has been reported to be highly prevalent in people living with HIV (PLWH) on antiretroviral therapy (ART) leading to the hypothesis that it may be an early...

Accessing HIV care may lead to earlier ascertainment of comorbidities in health care clients in Khayelitsha, Cape Town.

Successful antiretroviral rollout in South Africa has greatly increased the health of the HIV-positive population, and morbidity and mortality in PLHIV can increasingly be attributed to comorbidities rather than HIV/AIDS directly. Understanding this disease burden can inform health care planning for a growing population of ageing PLHIV. Anonymized routine administrative health data were analysed for all adults who accessed public health care in 2016-2017 in Khayelitsha subdistrict (Cape Town, South Africa). Selected comorbidities and age of ascertainment for comorbidities were described for all HIV-positive and HIV-negative healthcare clients, as well as for a subset of women who accessed maternal care. There were 172 937 adult individuals with a median age of 37 (IQR:30-48) years in the virtual cohort, of whom 48% (83 162) were HIV-positive. Median age of ascertainment for each comorbidity was lower in HIV-positive compared to HIV-negative healthcare clients, except in the case of tuberculosis. A subset of women who previously accessed maternal care, however, showed much smaller differences in the median age of comorbidity ascertainment between the group of HIV-positive and HIV-negative health care clients, except in the case of chronic kidney disease (CKD). Both HIV-positive individuals and women who link to maternal care undergo routine point-of-care screening for common diseases at younger ages, and this analysis suggests that this may lead to earlier diagnosis of common comorbidities in these groups. Exceptions include CKD, in which age of ascertainment appears lower in PLHIV than HIV-negative groups in all analyses suggesting that age of disease onset may indeed be earlier; and tuberculosis for which age of incidence has previously been shown to vary according to HIV status.

859. Suboptimal Uptake, Retention, and Adherence of Daily Oral PrEP Among People with OUD Receiving HCV Treatment

BackgroundDaily oral pre-exposure prophylaxis (PrEP) with tenofovir/emtricitabine (TDF/FTC) effectively prevents HIV among people who use drugs (PWUD). Despite rising rates of HIV incidence and injection drug use, PrEP use remains low and limited research exists on PrEP adherence and retention in this population.MethodsBased in Washington, DC and Baltimore, the ANCHOR investigation evaluated a community-based model of care collocating hepatitis C (HCV) therapy, medication for opioid use disorder (OUD), and PrEP in people with chronic HCV, OUD, and drug use within 1 year. PrEP counseling was offered from HCV treatment Day 0 until Week 24 and subjects could start any time during this window. PrEP patients were followed for 48 weeks and assessed for adherence by self-report and dried blood spot analysis of TDF. ANCHOR PrEP study enrollment and participant retention along the PrEP continuum.Results198 participants enrolled in ANCHOR, of whom 185 (93%) were HIV-negative. 29 subjects (16% of HIV-negative group) initiated PrEP. 116 subjects (63%) met 2014 CDC criteria for PrEP initiation due to IDU (82, 44%), sex (9, 5%), or both (25, 14%). Those who initiated were more likely to meet both CDC sexual and IDU risk criteria than those who declined PrEP (P=0.006). Providers recommended PrEP to 94 subjects (51%), which was associated with uptake (P=0.02). While median treatment duration was 104 days (IQR 28, 276), only 8 subjects were retained through Week 48. The most common reason for discontinuation was side effects in 7 subjects or 24% of PrEP subgroup. Treatment interruptions occurred in one-third of the PrEP subgroup. Adherence of 4 to 7 pills per week was variable over time by self-report and declined by TDF analysis. No HIV seroconversions occurred. Demographic and epidemiological background of the ANCHOR study population. Total duration, in days, on PrEP in the ANCHOR study. Discontinued participants are grouped by reason for cessation of therapy.PrEP Adherence Adherence to PrEP by ANCHOR study timepoint, assessed via self-report (above) and dried bloodspot analysis of tenofovir level (below).ConclusionIn this cohort of people with OUD and HCV, 16% of subjects started PrEP. While clinical recommendation was associated with uptake, high rates of disruption and discontinuation, compounded by variable pill adherence, made daily oral TDF/FTC a suboptimal preventive strategy in this cohort. Emerging PrEP modalities like long-acting injectables have potential to address these barriers, but PWUD have been excluded from their research and development to date. Additional work to identify vulnerable individuals and to promote use, adherence, and retention will be critical in implementing PrEP more effectively in this key population.Disclosures Sarah Kattakuzhy, MD, Gilead Sciences (Scientific Research Study Investigator, Research Grant or Support) Elana S.

Age at menopause in women living with HIV: a systematic review.

With improved HIV care, more women living with HIV (WLWH) are aging and entering menopause. Understanding any increased risk conferred by a potentially earlier menopause transition is important for the care of these women. There is conflicting literature regarding the association between HIV and an earlier onset of menopause. We conducted a systematic review to summarize the literature on the association between HIV and age at menopause. A search of Ovid MEDLINE, EMBASE, and Web of Science identified 894 articles. We included cohort studies that assessed age at menopause, primary ovarian insufficiency (POI), or early menopause among WLWH and used the World Health Organization definition of menopause as ≥12 months of amenorrhea. Nine studies were included and eight reported on age at menopause. Across studies, the age at menopause for WLWH fell between 46 and 50 years. Five of seven studies reported that WLWH had an earlier menopausal transition than HIV negative controls/the general population. Six studies reported on the prevalence of POI or early menopause among WLWH, with all studies demonstrating an increased prevalence of both among WLWH. Our systematic review summarizes the literature around HIV and age at menopause. Many studies reported a high prevalence of POI and early menopause among WLWH; a factor that may partially account for the observed lower age at menopause. As only one study included biochemical confirmation of menopause, it remains unclear whether individuals with early menopause or POI were truly menopausal or had prolonged amenorrhea due to other causes. Overall, our findings highlight the need for further investigation with studies that include an HIV negative control group and biochemical confirmation of menopause to better understand whether menopause truly is occurring earlier among WLWH.

Differential Signature of the Microbiome and Neutrophils in the Oral Cavity of HIV-Infected Individuals

HIV infection is associated with a wide range of changes in microbial communities and immune cell components of the oral cavity. The purpose of this study was to evaluate the oral microbiome in relationship to oral neutrophils in HIV-infected compared to healthy individuals. We evaluated oral washes and saliva samples from HIV-infected individuals (n=52) and healthy controls (n=43). Using 16S-rRNA gene sequencing, we found differential β-diversity using Principal Coordinate Analysis (PCoA) with Bray-Curtis distances. The α-diversity analysis by Faith’s, Shannon, and observed OTUs indexes indicated that the saliva samples from HIV-infected individuals harbored significantly richer bacterial communities compared to the saliva samples from healthy individuals. Notably, we observed that five species of Spirochaeta including Spirochaetaceae, Spirochaeta, Treponema, Treponema amylovorum, and Treponema azotonutricum were significantly abundant. In contrast, Helicobacter species were significantly reduced in the saliva of HIV-infected individuals. Moreover, we found a significant reduction in the frequency of oral neutrophils in the oral cavity of HIV-infected individuals, which was positively related to their CD4+ T cell count. In particular, we noted a significant decline in CD44 expressing neutrophils and the intensity of CD44 expression on oral neutrophils of HIV-infected individuals. This observation was supported by the elevation of soluble CD44 in the saliva of HIV-infected individuals. Overall, the core oral microbiome was distinguishable between HIV-infected individuals on antiretroviral therapy compared to the HIV-negative group. The observed reduction in oral neutrophils might likely be related to the low surface expression of CD44, resulting in a higher bacterial diversity and richness in HIV-infected individuals.
