RESUMEN

BACKGROUND: During the COVID-19 pandemic, online sexual health service delivery increased across Britain. We investigated inequalities in STI testing access and methods of access during the first year of the pandemic. METHODS: Natsal-COVID, an online-survey of people 18-59 years in Britain, explored sexual health experiences in the first year of the pandemic. We describe the socio-demographics of participants who used STI testing services and compare those who reported being "online service users", defined as using services with no direct clinician interactions (regardless of whether they also used other methods), with those who were exclusively "other service users", defined as face-to-face, telephone, or video calls. RESULTS: 246/6,064 participants (4.2%) reported STI testing between 03/2020-03/2021. Of those, 35.8% (95%CI 29.2-42.8) used online services. Online service users (compared to other service users) were more often white (74.9% (62.2-84.4) versus 68.5% (59.4-76.3)), less often had anxiety (39.0% (28.4-50.9) versus 57.2% (48.4-65.6)) and less often had disabilities (25.8% (16.8-37.4) versus 48.1% (39.4-56.9)). Among women (only), online users were more often in good health (91.4% (81.3-96.2) versus 69.3% (57.4-79.2)). CONCLUSIONS: More than one third of STI testers used online services during this period. Differences exist in the characteristics of people accessing online versus other testing services. These data suggest that online services were more likely to be accessed by groups with typically lower risk of poor sexual health (white and in good health). Further investigation is needed, especially if online services are the only option offered, as differences in ability to access services could widen inequalities.

RESUMEN

HIV point of care testing (POCT) is a common approach to expanding testing into non-specialised settings. Dental services have untapped potential to screen for health conditions including HIV. However, the perspectives of UK dental patients, dental professionals, and people with HIV are unknown. Ten focus groups were undertaken with dental patients, professionals, and people with HIV. The Framework method was used to analyse the qualitative data. Six themes were generated from the focus group data. The themes explored perceptions of HIV, the purpose, appropriateness, and acceptability of HIV testing in dental settings, and new processes that would need to be established in order to successfully implement point of care HIV testing in UK dental settings. Training needs were identified including communication skills and updates to current knowledge about HIV. HIV testing in dental settings is generally acceptable to dental patients, dental professionals, and PWH. However, of concern were logistical challenges and the risk of patients surprised at being offered an HIV test during a visit to the dentist. Nonetheless, the public health benefits of the intervention were well understood, i.e., early detection of HIV and initiation of treatment to improve health outcomes. Dental teams were able to generate novel solutions that could help to overcome contextual and logistical challenges to implementing HIV testing in dental settings.

RESUMEN

OBJECTIVES: Our objective was to describe the prevalence of cardiovascular disease (CVD) risk factors in people of African ancestry with HIV in the UK. METHODS: We conducted a cross-sectional analysis of CVD risk factors in Black people with HIV aged ≥40 years and estimated the 10-year CVD risk using QRISK®3-2018. Correlations between body mass index (BMI) and CVD risk factors were described using Pearson correlation coefficients, and factors associated with 10-year CVD risk ≥5% were described using logistic regression. RESULTS: We included 833 Black people with HIV and a median age of 54 years; 54% were female, 50% were living with obesity (BMI ≥30 kg/m2), 61% had hypertension, and 19% had diabetes mellitus. CVD risk >5% ranged from 2% in female participants aged 40-49 years to 99% in men aged ≥60 years, and use of statins ranged from 7% in those with CVD risk <2.5% to 64% in those with CVD risk ≥20%. BMI was correlated (R2 0.1-0.2) with triglycerides and diastolic blood pressure in women and with glycated haemoglobin, systolic and diastolic blood pressure, and total:high-density lipoprotein (HDL) cholesterol ratio in men. In both female and male participants, older age, blood pressure, diabetes mellitus, and kidney disease were strongly associated with CVD risk ≥5%, whereas obesity, total:HDL cholesterol, triglycerides, and smoking status were variably associated with CVD risk ≥5%. CONCLUSIONS: We report a high burden of CVD risk factors, including obesity, hypertension, and diabetes mellitus, in people of African ancestry with HIV in the UK. BMI-focused interventions in these populations may improve CVD risk while also addressing other important health issues.

RESUMEN

BACKGROUND: Sexually transmitted infections (STIs) are a serious public health issue in many countries. Online postal self-sampling (OPSS) is increasingly used to test for STIs, a trend accelerated by the COVID-19 pandemic. There remains limited understanding of how service users experience OPSS and what leads them to access it over clinic-based services, or vice versa. This research seeks to address these gaps, by undertaking a large qualitative study which sits within the ASSIST study, a mixed-methods, realist evaluation of OPSS. METHODS: Participants were recruited via clinic-based and online sexual health services in three case study areas in England. Purposive sampling was used to over-represent populations disproportionately affected by poor sexual health: young people; people of colour; men who have sex with men; and trans and non-binary people. Semi-structured interviews were analysed using Levesque's conceptual framework of access to healthcare. RESULTS: We interviewed 100 service users. Participants typically became aware of OPSS from sexual health services, the internet or word of mouth. Acceptability of OPSS was facilitated by the perceived privacy it offered over clinic-based services, which some participants found embarrassing to access. OPSS also enabled participants to overcome barriers to reaching clinic-based services, such as a lack of appointment availability, although difficulty obtaining OPSS kits in some areas undermined this. As all services in our case study areas were free to use, affordability did not significantly shape access, although OPSS enabled some participants to avoid costs associated with travelling to clinic-based services. Participants were usually able to engage with OPSS, finding it easy to use and reliable, although blood self-sampling was challenging for most. Participants valued the support offered by clinic-based services beyond STI testing, including the opportunity to access contraception or ask staff questions, and felt this was more appropriate when they had specific concerns about their sexual health, such as STI symptoms. CONCLUSIONS: Our findings constitute one of the largest qualitative studies to have explored OPSS and offer valuable insights to providers. OPSS shapes access to STI testing in a number of ways, including facilitating access in many circumstances, but users also want to retain access to clinic-based services, particularly for when they believe they need support beyond STI testing.

RESUMEN

BACKGROUND: Understanding the reasons for and consequences of bodyweight change in people living with HIV initiating antiretroviral therapy (ART) is crucial to optimising long-term health and wellbeing. We aimed to examine bodyweight trends and associated factors among individuals with well estimated dates of HIV-1 seroconversion. METHODS: In this cohort study, we pooled retrospective data from clinical records of participants in CASCADE aged 16 years and older recruited from clinics in France, Greece, the Netherlands, Spain, Sweden, the UK, and Canada. All participants had well estimated dates of HIV-1 seroconversion, seroconverted between Jan 1, 2007, and Dec 31, 2022 (HIV-1 positive antibody test within 12 months of an HIV-1 negative antibody test, or other laboratory evidence of seroconversion), initiated ART within 1 year of seroconversion, and were previously ART-naive. Participants were followed up to the time of data pooling (May 31, 2023). We modelled bodyweight changes after ART initiation by ART class, BMI categories, and other demographic characteristics using linear mixed models. FINDINGS: Of 15 755 potentially eligible participants, 5698 met inclusion criteria. Of those, 5148 (90·3%) were assigned male at birth, 517 (9·1%) were assigned female at birth, and 33 (0·6%) had sex not known. 2778 (48·8%) participants initiated integrase strand transfer inhibitor (INSTI)-based ART regimens, 1809 (31·7%) initiated protease inhibitor-based regimens, and 1111 (19·5%) initiated non-nucleoside reverse transcriptase inhibitor (NNRTI)-based regimens. The majority of participants were men who have sex with men (MSM; 4519 [79·3%]). Median age at seroconversion was 33·7 years (IQR 26·9-43·2). Bodyweight changes differed significantly by ART class within all baseline BMI categories (BMI <18·5 kg/m2 p=0·026, BMI 18·5-24·9 kg/m2 p<0·0001, BMI 25·0-29·9 kg/m2 p=0·0021, and BMI ≥30·0 kg/m2 p=0·0033; ART class and BMI interaction p=0·011). Participants with BMI less than 30 kg/m2 on regimens including both INSTI and tenofovir alafenamide gained 4·76 kg (95% CI 4·05-5·46) or more at 3 years. Of those with baseline BMI 18·5-24·9 kg/m2, 31·3% (95% CI 29·5-33·1) on INSTI-based regimens, 25·3% (23·0-27·7) on protease inhibitor-based regimens, 20·4% (18·8-22·9) on NNRTI-based regimens, 37·4% (33·9-40·9) on tenofovir alafenamide-based regimens, and 38·4% (34·6-42·1) on tenofovir alafenamide and INSTI-based regimens had gained more than 10% of their baseline bodyweight at 3 years. The greatest 3-year bodyweight gains by individuals on INSTI-based regimens and with BMI 18·5-24·9 kg/m2 were in women (5·63 kg [95% CI 4·92-6·35]), and people originating from sub-Saharan African (5·76 kg [5·06-6·46]), compared with MSM (3·82 kg [3·50-4·13]). INTERPRETATION: Our findings suggest a direct effect of INSTIs and tenofovir alafenamide on bodyweight gain, rather than a return to health effect. Given the known risk for cardiometabolic disease, bodyweight management needs to be part of the overall care of individuals prescribed these drugs.

RESUMEN

BACKGROUND: Understanding how HIV self-testing (HIVST) can meet the testing needs of gay, bisexual and other men who have sex with men (GBMSM) and trans people whose social networks vary is key to upscaling HIVST implementation. We aim to develop a contextual understanding of social networks and HIV testing needs among GBMSM (cis and transgender) and trans women in SELPHI (An HIV Self-testing Public Health Intervention), the UK's largest randomised trial on HIVST. METHODS: This study re-analysed qualitative interviews conducted from 2015 to 2020. Forty-three in-person interviews were thematically analysed using the Framework Method. Our analytic matrix inductively categorised participants based on the unmet needs for HIV testing and the extent of social network support. The role of social networks on HIVST behaviour was explored based on individuals' testing trajectories. RESULTS: Four distinct groups were identified based on their unmet testing needs and perceived support from social networks. Optimisation advocates (people with high unmet needs and with high network support, n = 17) strived to tackle their remaining barriers to HIV testing through timely support and empowerment from social networks. Privacy seekers (people with high unmet needs and with low network support, n = 6) prioritised privacy because of perceived stigma. Opportunistic adopters (people with low unmet needs and with high network support, n = 16) appreciated social network support and acknowledged socially privileged lives. Resilient testers (people with low unmet needs and with low network support, n = 4) might hold potentially disproportionate confidence in managing HIV risks without sustainable coping strategies for potential seroconversion. Supportive social networks can facilitate users' uptake of HIVST by: (1) increasing awareness and positive attitudes towards HIVST, (2) facilitating users' initiation into HIVST with timely support and (3) affording participants an inclusive space to share and discuss testing strategies. CONCLUSIONS: Our proposed categorisation may facilitate the development of differentiated person-centred HIVST programmes. HIVST implementers should carefully consider individuals' unmet testing needs and perceived levels of social support, and design context-specific HIVST strategies that link people lacking supportive social networks to comprehensive HIV care.

RESUMEN

BACKGROUND: Unmet need within sexual and reproductive health (SRH) is a concept that is difficult to define and measure. This qualitative Delphi exercise was used to ascertain the opinions of SRH professionals on the conceptualisation and measurement of unmet need within SRH. METHODS: This exercise was carried out in two rounds. In the first round, respondents responded narratively to three prompts, which were then used to create a series of statements. In the second round, participants responded narratively to the statements created in the first round. Responses from both rounds were then coded and analysed thematically. RESULTS: Participants felt that an understanding of unmet need is an important part of SRH service design and provision, and believed that certain populations are often underrepresented within the datasets that are used to assess unmet need. Many respondents felt that a full understanding of unmet need within SRH would only come from involvement of relevant stakeholders in the process of investigating unmet need, and that qualitative methods may also have a role to play in gaining a more holistic understanding of unmet need within SRH. CONCLUSIONS: Respondents within this study felt that unmet need is complex concept that has a significant impact on service delivery and the outcomes and experiences of the most vulnerable populations. We need to improve our understanding of unmet need and prioritise stakeholder voices if we want to create interventions that address unmet need within SRH.

RESUMEN

Background: The 2022-2024 global mpox outbreak, occurring primarily in the sexual networks of gay, bisexual and other men who have sex with men (GBMSM), has not been accompanied by a focus on patient perspectives of illness. We explore the experiences of GBMSM diagnosed with mpox in England to understand needs for social and clinical support. Methods: In-depth interviews (March/July 2023) were conducted with 22 GBMSM diagnosed with mpox in 2022, randomly selected from a national mpox surveillance database, and 4 stakeholders from clinical/community-based organisations. Interviews covered experiences of illness, testing, diagnosis, treatment and contact tracing, and were recorded, transcribed and analysed with a thematic framework. Findings: Media coverage drawing on homophobic stereotypes around sex between men contributed to feelings of stigma and shame. GBMSM living with HIV appeared to cope better with mpox stigma, drawing on their experiences of being diagnosed with HIV for resilience. Younger GBMSM with less experience of stigmatising illness found mpox diagnosis more traumatic and sometimes required support beyond what was provided. Accessing testing could be complicated when healthcare professionals did not recognise mpox symptoms. Men felt information on course of illness, isolation and vaccination after recovery was often inconsistent and contradictory. GBMSM described that care from sexual health and infectious disease units usually better met their emotional and medical needs. This was frequently linked by men to these services having skills in working with the GBMSM community and managing infection risk sensitively. General hospital services and centralised contact tracing could increase feelings and experiences of stigma as some staff were perceived to lack skills in supporting GBMSM and, sometimes, clinical knowledge. Long-term impacts described by men included mental health challenges, urethral/rectal symptoms and life-changing disability. Interpretation: In this study stigma was a central feature of mpox illness among GBMSM and could be exacerbated or lessened depending on the clinical and social support provided. Involving communities affected by outbreaks in co-producing, planning and delivering care (including contact-tracing) may help improve support provided.

RESUMEN

BACKGROUND AND AIMS: HBV and HIV coinfection is a common occurrence globally, with significant morbidity and mortality. Both viruses lead to immune dysregulation including changes in natural killer (NK) cells, a key component of antiviral defense and a promising target for HBV cure strategies. Here we used high-throughput single-cell analysis to explore the immune cell landscape in people with HBV mono-infection and HIV/HBV coinfection, on antiviral therapy, with emphasis on identifying the distinctive characteristics of NK cell subsets that can be therapeutically harnessed. APPROACH AND RESULTS: Our data show striking differences in the transcriptional programs of NK cells. HIV/HBV coinfection was characterized by an over-representation of adaptive, KLRC2 -expressing NK cells, including a higher abundance of a chemokine-enriched ( CCL3/CCL4 ) adaptive cluster. The NK cell remodeling in HIV/HBV coinfection was reflected in enriched activation pathways, including CD3ζ phosphorylation and ZAP-70 translocation that can mediate stronger antibody-dependent cellular cytotoxicity responses and a bias toward chemokine/cytokine signaling. By contrast, HBV mono-infection imposed a stronger cytotoxic profile on NK cells and a more prominent signature of "exhaustion" with higher circulating levels of HBsAg. Phenotypic alterations in the NK cell pool in coinfection were consistent with increased "adaptiveness" and better capacity for antibody-dependent cellular cytotoxicity compared to HBV mono-infection. Overall, an adaptive NK cell signature correlated inversely with circulating levels of HBsAg and HBV-RNA in our cohort. CONCLUSIONS: This study provides new insights into the differential signature and functional profile of NK cells in HBV and HIV/HBV coinfection, highlighting pathways that can be manipulated to tailor NK cell-focused approaches to advance HBV cure strategies in different patient groups.

RESUMEN

BACKGROUND: Women aged 16-24 in England have a high burden of sexual and reproductive morbidity, with particularly poor outcomes among people living in more deprived areas (including racially minoritised populations). This analysis used national data to examine the disparities within sexual and reproductive outcomes among this population and to assess whether the patterns of inequality were consistent across all outcomes. METHODS: Within this ecological study, univariable and multivariable Poisson regression analyses of neighbourhood-level data from national data sets were carried out to investigate the relationships of deprivation and ethnicity with each of six dependent variables: gonorrhoea and chlamydia testing rates, gonorrhoea and chlamydia test positivity rates, and abortion and repeat abortion rates. RESULTS: When comparing Index of Multiple Deprivation (IMD) decile 1 (most deprived) and IMD decile 10 (least deprived), chlamydia (RR 0.65) and gonorrhoea (0.79) testing rates, chlamydia (0.70) and gonorrhoea (0.34) positivity rates, abortion rates (0.45) and repeat abortion rates (0.72) were consistently lower in IMD decile 10 (least deprived). Similarly, chlamydia (RR 1.24) and gonorrhoea positivity rates (1.92) and repeat abortion rates (1.31) were higher among black women than white women. Results were similar when both ethnicity and deprivation were incorporated into multivariable analyses. CONCLUSION: We found similar patterns of outcome inequality across a range of sexual and reproductive outcomes, despite multiple differences in the drivers of each outcome. Our analysis suggests that there are broad structural causes of inequality across sexual and reproductive health that particularly impact the health of deprived and black populations.

RESUMEN

OBJECTIVES: This qualitative sub-study aimed to explore how cisgender gay, bisexual, and other men who have sex with men (cis-GBMSM) and transgender people who reported non-consensual sex (NCS) accessed health care services, what barriers they faced, and how this experience influenced subsequent HIV testing. METHODS: SELPHI is an online randomized controlled trial evaluating both acceptability and efficiency of HIV-self testing among cis-GBMSM and transgender people. Semi-structured interviews were conducted, audio-recorded, transcribed, and analysed through a framework analysis, as a qualitative sub-study. We identified narratives of NCS from interviews and investigated experiences of cis-GBMSM and transgender people accessing health care services following sexual assault. RESULTS: Of 95 participants, 15 (16%) spontaneously reported NCS. Participants reported a broad range of NCS, including partner's coercive behaviours, non-consensual removal of condoms, and rapes. All feared HIV transmission, leading them to test for HIV, underlining a marked lack of awareness of post-exposure prophylaxis (PEP). Most had negative experiences in communicating with reception staff in sexual health clinics following these incidents. A lack of confidentiality and empathy was described in these situations of psychological distress. Clinic visits were primarily focused on testing for HIV and sexually transmitted infection, and generally no specific psychological support was offered. Getting a negative HIV result was a key step in regaining control for people who experienced NCS. CONCLUSIONS: Sexual health care providers should take care to more fully address the issue of NCS with cis-GBMSM and transgender people when it arises. Recognizing and managing the emotional impact of NCS on affected patients would prevent negative experiences and increase confidence in care.

RESUMEN

OBJECTIVES: To describe HIV care outcomes in people of Black ethnicities living in England during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2; coronavirus disease 2019 [COVID-19]) pandemic. METHODS: This was an observational cohort study of people of self-reported Black ethnicities attending for HIV care at nine HIV clinics across England. The primary outcome was a composite of antiretroviral therapy (ART) interruption and HIV viraemia (HIV RNA ≥200 copies/mL) ascertained via self-completed questionnaires and review of medical records. We used multivariable logistic regression to explore associations between ART interruption/HIV viraemia and demographic factors, pre-pandemic HIV immunovirological control, comorbidity status, and COVID-19 disease and vaccination status. RESULTS: We included 2290 people (median age 49.3 years; 56% female; median CD4 cell count 555 cells/mm3; 92% pre-pandemic HIV RNA <200 copies/mL), of whom 302 (13%) reported one or more ART interruption, 312 (14%) had documented HIV viraemia ≥200 copies/mL, and 401 (18%) experienced the composite endpoint of ART interruption/HIV viraemia. In multivariable analysis, a pre-pandemic HIV RNA <200 copies/mL (odds ratio [OR] 0.21; 95% confidence interval [CI] 0.15-0.30) and being vaccinated against SARS-CoV-2 (OR 0.41; 95% CI 0.30-0.55) were associated with reduced odds of ART interruption/HIV viraemia; pandemic-related disruptions to HIV care were common self-reported additional factors. CONCLUSIONS: During the COVID-19 pandemic, one in six people of Black ethnicities in this HIV cohort experienced an ART interruption/HIV viraemia. Some of these episodes resulted from pandemic-related healthcare disruptions. Associations with suboptimal engagement in HIV care pre-pandemic and not being vaccinated against SARS-CoV-2 suggest that wider health beliefs and/or poor healthcare access may have been contributory factors.

RESUMEN

Dynamic regulation of cellular metabolism is important for maintaining homeostasis and can directly influence immune cell function and differentiation, including NK cell responses. Persistent HIV-1 infection leads to a state of chronic immune activation, NK cell subset redistribution, and progressive NK cell dysregulation. In this study, we examined the metabolic processes that characterize NK cell subsets in HIV-1 infection, including adaptive NK cell subpopulations expressing the activating receptor NKG2C, which expand during chronic infection. These adaptive NK cells exhibit an enhanced metabolic profile in HIV-1- individuals infected with human cytomegalovirus (HCMV). However, the bioenergetic advantage of adaptive CD57+NKG2C+ NK cells is diminished during chronic HIV-1 infection, where NK cells uniformly display reduced oxidative phosphorylation (OXPHOS). Defective OXPHOS was accompanied by increased mitochondrial depolarization, structural alterations, and increased DRP-1 levels promoting fission, suggesting that mitochondrial defects are restricting the metabolic plasticity of NK cell subsets in HIV-1 infection. The metabolic requirement for the NK cell response to receptor stimulation was alleviated upon IL-15 pretreatment, which enhanced mammalian target of rapamycin complex 1 (mTORC1) activity. IL-15 priming enhanced NK cell functionality to anti-CD16 stimulation in HIV-1 infection, representing an effective strategy for pharmacologically boosting NK cell responses.

RESUMEN

To investigate the symptoms of SARS-CoV-2 infection, their dynamics and their discriminatory power for the disease using longitudinally, prospectively collected information reported at the time of their occurrence. We have analysed data from a large phase 3 clinical UK COVID-19 vaccine trial. The alpha variant was the predominant strain. Participants were assessed for SARS-CoV-2 infection via nasal/throat PCR at recruitment, vaccination appointments, and when symptomatic. Statistical techniques were implemented to infer estimates representative of the UK population, accounting for multiple symptomatic episodes associated with one individual. An optimal diagnostic model for SARS-CoV-2 infection was derived. The 4-month prevalence of SARS-CoV-2 was 2.1%; increasing to 19.4% (16.0%-22.7%) in participants reporting loss of appetite and 31.9% (27.1%-36.8%) in those with anosmia/ageusia. The model identified anosmia and/or ageusia, fever, congestion, and cough to be significantly associated with SARS-CoV-2 infection. Symptoms' dynamics were vastly different in the two groups; after a slow start peaking later and lasting longer in PCR+ participants, whilst exhibiting a consistent decline in PCR- participants, with, on average, fewer than 3 days of symptoms reported. Anosmia/ageusia peaked late in confirmed SARS-CoV-2 infection (day 12), indicating a low discrimination power for early disease diagnosis.

RESUMEN

OBJECTIVES: To describe the clinical epidemiology of COVID-19 in people of black ethnicity living with HIV in the UK. METHODS: We investigated the incidence and factors associated with COVID-19 in a previously established and well-characterized cohort of black people with HIV. Primary outcomes were COVID-19 acquisition and severe COVID-19 disease (requiring hospitalization and/or resulting in death). Cumulative incidence was analysed using Nelson-Aalen methods, and associations between demographic, pre-pandemic immune-virological parameters, comorbidity status and (severe) COVID-19 were identified using Cox regression analysis. RESULTS: COVID-19 status was available for 1847 (74%) of 2495 COVID-AFRICA participants (median age 49.6 years; 56% female; median CD4 cell count = 555 cells/µL; 93% HIV RNA <200 copies/mL), 573 (31%) of whom reported at least one episode of COVID-19. The cumulative incidence rates of COVID-19 and severe COVID-19 were 31.0% and 3.4%, respectively. Region of ancestry (East/Southern/Central vs. West Africa), nadir CD4 count and kidney disease were associated with COVID-19 acquisition. Diabetes mellitus [adjusted hazard ratio (aHR) = 2.39, 95% confidence interval (CI): 1.26-4.53] and kidney disease (aHR = 2.53, 95% CI: 1.26-4.53) were associated with an increased risk, and recent CD4 count >500 cells/µL (aHR = 0.49, 95% CI: 0.25-0.93) with a lower risk of severe COVID-19. CONCLUSIONS: Region of ancestry was associated with COVID-19 acquisition, and immune and comorbidity statuses were associated with COVID-19 disease severity in people of black ethnicity living with HIV in the UK.

RESUMEN

OBJECTIVE: To investigate the association of age at antiretroviral therapy (ART) initiation with CD4 +  : CD8 + T-cell ratio in virally suppressed people with HIV on long-term ART, and to characterize potential CD4 +  : CD8 + ratio recovery in this population by age. DESIGN: A longitudinal study of people attending an HIV clinic at the Royal Free Hospital NHS Trust, London, who initiated ART between 2001 and 2015, and achieved and maintained HIV-1 viral suppression (viral load <1,000 copies/ml). The association of age group at ART initiation with CD4 +  : CD8 + ratio at 5 and 10 years was assessed. METHODS: Multivariable linear regression was used to investigate the relationship between age at ART initiation and log CD4 +  : CD8 + ratio, adjusting for demographic factors (gender/HIV transmission route, ethnicity), baseline CD4 + count and calendar year. RESULTS: The sample included 1859 people aged 20-78 (75% men, 56% white ethnicity). Overall, median CD4 +  : CD8 + T-cell ratio increased from 0.24 at baseline to 0.77 at year 5 and 0.88 at year 10. Ratios increased among all age groups in unadjusted and adjusted models but increased less among older ages (baseline ages 60-69 and 70-79). Median ratios at year 5 were 0.85, 0.80, 0.72, 0.76, 0.6, and 0.44, respectively, among people aged 20-29, 30-39, 40-49, 50-59, 60-69 and 70-79 years at baseline. CONCLUSION: In a virally suppressed London population, age had a substantial impact on CD4 +  : CD8 + ratio recovery, especially for those starting ART after age 60 years. Results may indicate the level of CD4 +  : CD8 + ratio recovery possible in an HIV-positive, virally suppressed, aging population.

RESUMEN

Natural killer (NK) cell subsets with adaptive properties are emerging as regulators of vaccine-induced T and B cell responses and are specialized towards antibody-dependent functions contributing to SARS-CoV-2 control. Although HIV-1 infection is known to affect the NK cell pool, the additional impact of SARS-CoV-2 infection and/or vaccination on NK cell responses in people living with HIV (PLWH) has remained unexplored. Our data show that SARS-CoV-2 infection skews NK cells towards a more differentiated/adaptive CD57+FcεRIγ- phenotype in PLWH. A similar subset was induced following vaccination in SARS-CoV-2 naïve PLWH in addition to a CD56bright population with cytotoxic potential. Antibody-dependent NK cell function showed robust and durable responses to Spike up to 148 days post-infection, with responses enriched in adaptive NK cells. NK cell responses were further boosted by the first vaccine dose in SARS-CoV-2 exposed individuals and peaked after the second dose in SARS-CoV-2 naïve PLWH. The presence of adaptive NK cells associated with the magnitude of cellular and humoral responses. These data suggest that features of adaptive NK cells can be effectively engaged to complement and boost vaccine-induced adaptive immunity in potentially more vulnerable groups such as PLWH.

RESUMEN

Previous research has documented the various challenges people living with HIV face as they navigate intimate relationships, including what is often referred to as disclosure. In studies of gay, bisexual and other men who have sex with men, the issue of telling or not telling others about an HIV-positive status has been examined primarily in relation to communication with sexual partners, with few studies focusing on other aspects of intimacy. Drawing on interviews with gay men living with HIV, conducted in four clinics in London, this article explores the narratives of men who have been asked by female friends about the possibility of being a sperm donor. The narratives highlight layers of complexity which have received little attention, not only in research on HIV but also in studies of sperm donation and co-parenting. The article advances dialogue between these two largely separate bodies of work. Our data suggest that reluctance to share an HIV-positive status with others can be an important factor in deciding how to answer the 'sperm donor question'. Examining reproductive relationships of a specific kind - those based on friendships between women and gay men - the article develops the understanding of how secrecy about HIV shapes intimate lives.

RESUMEN

OBJECTIVES: Recently acquired HIV is a critical time when people may experience debilitating symptoms and is when they are most likely to pass HIV on. Qualitative research offers insights into lived experiences and a deeper understanding of the contextual factors underlying HIV acquisition. We aimed to synthesize qualitative literature on recently acquired HIV. DESIGN: Systematic review and textual narrative synthesis. METHODS: We searched MEDLINE, CINAHL Plus, PsycINFO and Sociology Database. Articles were screened, and two authors completed full text review and data extraction. Quality appraisal was conducted (Critical Appraisal Skills Programme Qualitative Studies Checklist) and certainty of findings graded (GRADE-CERQual). RESULTS: We reviewed 1890 articles (1554 following de-duplication), excluding 1539. Fifteen articles were included and an additional article was included after updating the search. We identified 15 themes, three of which we have high confidence in: recent acquisition of HIV facilitates understanding of circumstances of HIV acquisition; indeterminate HIV tests generate uncertainty and anxiety; and people with recently acquired HIV are motivated to reduce risk of onward transmission. CONCLUSIONS: Our findings highlight the importance of continued research into recently acquired HIV, as well as the need for support to manage the emotional impact of indeterminate test results and negotiate risk reduction. We found no studies exploring sexual risk in the context of recently acquired HIV, or use of pre-exposure prophylaxis or treatment as prevention. The literature is primarily focused on HIV acquisition from an individual and behavioural perspective, neglecting important aspects of lived experience such as immediate ART, stigma, and health and wellbeing.

RESUMEN

BACKGROUND: The potential of HIV self-testing (HIVST) to cause harm is a concern hindering widespread implementation. The aim of this paper is to understand the relationship between HIVST and harm in SELPHI (An HIV Self-testing Public Health Intervention), the largest randomised trial of HIVST in a high-income country to date. METHODS: 10 111 cis and trans men who have sex with men (MSM) recruited online (geolocation social/sexual networking apps, social media), aged 16+, reporting previous anal intercourse and resident in England or Wales were first randomised 60/40 to baseline HIVST (baseline testing, BT) or not (no baseline testing, nBT) (randomisation A). BT participants reporting negative baseline test, sexual risk at 3 months and interest in further HIVST were randomised to three-monthly HIVST (repeat testing, RT) or not (no repeat testing, nRT) (randomisation B). All received an exit survey collecting data on harms (to relationships, well-being, false results or being pressured/persuaded to test). Nine participants reporting harm were interviewed in-depth about their experiences in an exploratory substudy; qualitative data were analysed narratively. RESULTS: Baseline: predominantly cis MSM, 90% white, 88% gay, 47% university educated and 7% current/former pre-exposure prophylaxis (PrEP) users. Final survey response rate was: nBT=26% (1056/4062), BT=45% (1674/3741), nRT=41% (471/1147), RT=50% (581/1161).Harms were rare and reported by 4% (n=138/3691) in exit surveys, with an additional two false positive results captured in other study surveys. 1% reported harm to relationships and to well-being in BT, nRT and RT combined. In all arms combined, being pressured or persuaded to test was reported by 1% (n=54/3678) and false positive results in 0.7% (n=34/4665).Qualitative analysis revealed harms arose from the kit itself (technological harms), the intervention (intervention harms) or from the social context of the participant (socially emergent harms). Intervention and socially emergent harms did not reduce HIVST acceptability, whereas technological harms did. DISCUSSION: HIVST harms were rare but strategies to link individuals experiencing harms with psychosocial support should be considered for HIVST scale-up. TRIAL REGISTRATION NUMBER: ISRCTN20312003.
