Introduction Anti-retroviral therapy (ART) simplification strategies are needed for treatment-experienced people with HIV (PWH) and multidrug-resistant viruses. These individuals are commonly treated with boosted ART regimens and are thereby at risk for harmful drug-drug interactions (DDI). In this trial, we aim to assess the efficacy of the combination doravirine, dolutegravir and lamivudine (DOR/DTG/3TC) among people with a history of virological failure who receive boosted ART.Methods and analysis B-Free is a multistage, randomised, multicentre, open-label, non-inferiority trial, embedded within the Swiss HIV Cohort Study and conducted in collaboration with cohorts of PWH in the Netherlands and France. Cohort participants with a history of ART change due to virologic failure and who maintain HIV virologic suppression with an ART regimen consisting of a pharmacological booster and at least two drugs from classes other than nucleoside reverse transcriptase inhibitors are included. Patients with major drug resistance mutations against DTG or DOR and individuals with chronic hepatitis B virus infection are not eligible for the study. Individuals are randomised 1:1 to either receiving co-formulated DTG/3TC and DOR once daily or continuing their boosted ART regimen. The primary outcome is the proportion of individuals lacking virologic control (HIV-RNA ≥50 cp/mL) at 48 weeks, according to the Food and Drug Administration snapshot algorithm. Changes in DDI burden (assessed using a DDI score), treatment satisfaction (assessed using the HIV Treatment Satisfaction Questionnaire), quality of life and mental health represent key secondary outcomes. Additional secondary outcomes include the proportion of individuals developing new resistance-associated mutations and changes in quality of life and mental health. In a qualitative substudy, we will conduct semistructured interviews with a subset of participants to assess their expectations and experiences towards HIV treatment and clinical research in general. Enrolling 210 individuals will provide 80% power to demonstrate non-inferiority, defined as less than 8% absolute increase in loss of viral suppression in individuals randomised to DOR/DTG/3TC (one-sided type I error rate of 0.025).Ethics and dissemination The study was approved by the competent ethics committees (reference number BASEC 2023–01060) and the regulatory authority Swissmedic (reference number 701655) in Switzerland before the enrolment of the first participant. Approval by the European Medicines Agency and local ethical committees in the Netherlands and France will be obtained prior to including participants in these countries. Participant’s written informed consent is obtained by the investigators before enrolment. The results of all major B-Free study outcomes will be submitted to peer-reviewed journals that enable Open Access publication.Trial registration number Swiss National Clinical Trials Portal (SNCTP000005686, registered on 06 November 2023) and Clinicaltrials.gov (NCT06037564, registered on 07 September 2023).

Introduction CARISEL is an implementation–effectiveness “hybrid” study examining the perspectives of people living with HIV-1 (patient study participants [PSPs]) on cabotegravir (CAB) plus rilpivirine (RPV) long-acting (LA) dosed every 2 months (Q2M) across 5 European countries. Methods PSPs completed questionnaires on acceptability (Acceptability of Intervention Measure), appropriateness (Intervention Appropriateness Measure), and feasibility (Feasibility of Intervention Measure) at their first (Month [M] 1), third (M4), and seventh (M12) injection visits. Semistructured qualitative interviews were also conducted. Results Overall, 437 PSPs were enrolled, of whom 430 received treatment. Median (interquartile range) age was 44 (37-51) years, 25.3% (n = 109/430) were female (sex at birth), and 21.9% (n = 94/430) were persons of color. Across time points, PSPs found CAB + RPV LA highly acceptable, appropriate, and feasible (mean scores ≥4.47/5). Qualitative data supported these observations. Conclusions PSPs found CAB + RPV LA Q2M to be an acceptable, appropriate, and feasible treatment option.

Abstract Introduction Transgender women are at increased risk of acquiring HIV. Earlier studies reported lower retention in HIV care, antiretroviral therapy uptake, adherence and viral suppression. We assessed the stages of the HIV care continuum of transgender women in the Netherlands over an 11‐year period. In addition, we assessed new HIV diagnoses and late presentation, as well as disengagement from care, between 2011 and 2021. Methods Using data from the Dutch national ATHENA cohort, we separately assessed viral suppression, as well as time to achieving viral suppression, among transgender women for each year between 2011 and 2021. We also assessed trends in new HIV diagnoses and late presentation (CD4 count of

Summary: Human genetic studies of critical COVID-19 pneumonia have revealed the essential role of type I interferon-dependent innate immunity to SARS-CoV-2 infection. Conversely, an association between the HLA-B∗15:01 allele and asymptomatic SARS-CoV-2 infection in unvaccinated individuals was recently reported, suggesting a contribution of pre-existing T cell-dependent adaptive immunity. We report a lack of association of classical HLA alleles, including HLA-B∗15:01, with pre-omicron asymptomatic SARS-CoV-2 infection in unvaccinated participants in a prospective population-based study in the United States (191 asymptomatic vs. 945 symptomatic COVID-19 cases). Moreover, we found no such association in the international COVID Human Genetic Effort cohort (206 asymptomatic vs. 574 mild or moderate COVID-19 cases and 1,625 severe or critical COVID-19 cases). Finally, in the Human Challenge Characterisation study, the three HLA-B∗15:01 individuals infected with SARS-CoV-2 developed symptoms. As with other acute primary infections studied, no classical HLA alleles favoring an asymptomatic course of SARS-CoV-2 infection were identified.

Medicine ,Science - Abstract
BackgroundIndividuals who have recently acquired HIV represent a unique population because the time frame since HIV acquisition is relatively short and identification of missed HIV prevention opportunities is, therefore, closer to real time and less subject to recall bias. Identifying prevention measures used and missed opportunities for using them, can help stop further HIV transmission.ObjectivesThis systematic review aims to synthesise current global evidence on uptake of HIV prevention methods among people with recently acquired HIV from 2007, the year that the concept of ART as a prevention method was first introduced.Methods and analysisMEDLINE/PubMed, EMBASE, PsycINFO, Cochrane and Web of Science databases, will be searched for articles published January 2007-December 2023. Eligible studies will be those that reported on HIV prevention methods among people with recently acquired HIV. Quality assessment of the studies selected will be undertaken, and reporting of the systematic review will be informed by Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.ResultsThe systematic review is expected to provide comprehensive insights into the uptake, use and adherence to HIV prevention methods among individuals with recently acquired HIV. Analysis anticipates identifying gaps in prevention coverage, missed opportunities for intervention, and variations in access to and use of prevention strategies. Sociodemographic, personal, and behavioural factors influencing prevention uptake and adherence will also be synthesised.ConclusionsThe findings will be of key relevance to researchers, healthcare providers including third sector organisations/ community groups and policymakers, as they will offer insight into better understanding of missed or failed HIV prevention efforts and will help ensure future efforts meet the needs of those in need of them.

Medicine ,Science - Abstract
IntroductionHIV treating physicians in the Netherlands follow the guidelines of the Department of Health and Human Services (DHHS). Most of these recommended initial regimens are single-tablet regimens (STRs), which incur higher costs. By the end of 2017, generic NRTI backbones had become widely available, offering a potentially cheaper multi-tablet regimen. This study aimed to evaluate guideline compliance in people with HIV who started antiretroviral therapy (ART), the uptake of generic multi-tablet regimens (gMTRs), and associated medication costs.MethodsThis retrospective cohort study used data from the Dutch HIV Monitoring Foundation to determine the proportion of treatment-naïve people entering care who initiated ART according to the DHHS and type of ART regimens prescribed between January 2016 and December 2020. We analyzed ART prescriptions, both at the national level and per individual HIV treatment centers. We calculated the monthly ART costs based on Dutch medicine prices listed on www.medicijnkosten.nl for each calendar year.ResultsIn 2016, an integrase inhibitor-containing regimen was initiated in 77.3% which increased to 87.8% in 2020. The compliance rate to DHHS-recommended initial regimens ranged from 82.8% in 2016 to 90.9% in 2020. Most patients received single-tablet regimens, 81.3% in 2016 to 60.3% in 2020. After the introduction the gMTRs showed a steady increase from 17.8% in 2018 to 37.8% in 2020. The cost of the first-line regimen per patient decreased by 22.9% in 2020 compared with 2017. The decrease was larger in centers where treatment-naïve individuals with HIV were preferentially initiated on a gMTR.ConclusionsThere was a high compliance to the "DHHS-recommended initial regimens for most people with HIV" in the Netherlands. Most people who initiated ART received STRs, although the percentage of people who started on STRs gradually decreased over time. The use of gMTRs increased over time and was associated with lower medication costs.

Abstract Background As highly effective therapy against hepatitis C virus (HCV) infection is available with rapid uptake, there is newfound optimism for HCV elimination. Nevertheless, certain key populations have a high risk of HCV reinfection, in particular men who have sex with men (MSM) in Western European countries. Modelling data indicate that HCV elimination will not be feasible without reduction in risk behaviour, thus supporting the need for effective interventions aimed at reducing risk behaviour and preventing reinfections in MSM. Methods The ICECREAM study is an international, multi-centred, phase 2, 3-arm randomised trial comparing run-in and intervention periods enrolling MSM with a history of a cured or spontaneously cleared HCV infection. Individuals are followed in routine care for 6 months (i.e. run-in period) and then randomly allocated (1:1:1) to one of the following: a tailored, interactive online risk-reduction behavioural intervention, a validated home-based HCV-RNA self-sampling test service using dried blood spots, or a combination of both. After randomisation, individuals are followed every 6 months until 18 months (i.e. intervention period). Interventions are delivered in addition to standard of care. Online questionnaire measuring risk behaviour over the past 6 months is administered at every visit. The primary outcome is the proportion at risk of HCV infection during run-in versus intervention periods assessed by using the HCV-MOSAIC risk score. The risk score consists of six self-reported HCV-related risk behaviours. Secondary outcomes include incidence of HCV reinfection, changes in the individual risk behaviour items and changes in sexual well-being since changes in sexual behaviour may have an impact on sexual experience. Two hundred forty-six MSM aged 18 years or older will be invited to participate. Discussion The ICECREAM study is a trial aimed at establishing interventions that could effectively decrease the incidence of HCV re-infection in MSM with a previous HCV infection. By offering an online behavioural risk-reduction intervention and HCV-RNA self-sampling, both of which are aimed to influence risk behaviour, we are able to provide products to at-risk MSM that could further reduce population-level HCV incidence and ultimately help reach HCV micro-elimination.

Medicine - Abstract
Introduction Successful antiviral therapy has transformed HIV infection into a chronic condition, where optimising quality of life (QoL) has become essential for successful lifelong treatment. Patient-reported outcome measures (PROMs) can signal potential physical and mental health problems related to QoL. This study aims to determine whether PROMs in routine clinical care improve quality of care as experienced by people with HIV (PWH).Methods and analysis We report the protocol of a multicentre longitudinal cohort studying PWH at Amsterdam University Medical Centres in the Netherlands. PROMs are offered annually to patients via the patient portal of the electronic health record. Domains include anxiety, depression, fatigue, sleep disturbances, social isolation, physical functioning, stigma, post-traumatic stress disorder, adherence, drug and alcohol use and screening questions for sexual health and issues related to finances, housing and migration status. Our intervention comprises (1) patients’ completion of PROMs, (2) discussion of PROMs scores during annual consultations and (3) documentation of follow-up actions in an individualised care plan, if indicated. The primary endpoint will be patient-experienced quality of care, measured by the Patient Assessment of Chronic Illness Care, Short Form (PACIC-S). Patients will provide measurements at baseline, year 1 and year 2. We will explore change over time in PACIC-S and PROMs scores and examine the sociodemographical and HIV-specific characteristics of subgroups of patients who participated in all or only part of the intervention to ascertain whether benefit has been achieved from our intervention in all subgroups.Ethics and dissemination Patients provide consent for the analysis of data collected as part of routine clinical care to the AIDS Therapy Evaluation in the Netherlands study (ATHENA) cohort through mechanisms described in Boender et al. Additional ethical approval for the analysis of these data is not required under the ATHENA cohort protocol. The results will be presented at national and international academic meetings and submitted to peer-reviewed journals for publication.

ABSTRACT Few studies have comprehensively compared severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine-induced and hybrid B- and T-cell responses in people with HIV (PWH) to those in comparable controls without HIV. We included 195 PWH and 246 comparable controls from the AGEhIV COVID-19 substudy. A positive nucleocapsid antibody (INgezim IgA/IgM/IgG) or self-reported PCR test defined prior SARS-CoV-2 infection. SARS-CoV-2 anti-spike (anti-S) IgG titers and anti-S IgG production by memory B cells were assessed. Neutralizing antibody titers were determined in a subset of participants. T-cell responses were assessed by gamma interferon (IFN-γ) release and activation-induced marker assay. We estimated mean differences in postvaccination immune responses (β) between levels of determinants. Anti-S IgG titers and anti-S IgG production by memory B cells were not different between PWH and controls. Prior SARS-CoV-2 infection (β = 0.77), receiving mRNA vaccine (β = 0.56), female sex (β = 0.24), fewer days between last vaccination and sampling (β = 0.07), and a CD4/CD8 ratio of

Medicine - Abstract
Introduction Despite the availability of pre-exposure prophylaxis (PrEP) and antiretroviral therapy (ART), 21 793 people were newly diagnosed with HIV in Europe in 2019. The Concerted action on seroconversion to AIDS and death in Europe study aims to understand current drivers of the HIV epidemic; factors associated with access to, and uptake of prevention methods and ART initiation; and the experiences, needs and outcomes of people with recently acquired HIV.Methods and analysis This longitudinal observational study is recruiting participants aged ≥16 years with documented laboratory evidence of HIV seroconversion from clinics in Canada and six European countries. We will analyse data from medical records, self-administered questionnaires, semistructured interviews and participatory photography. We will assess temporal trends in transmitted drug resistance and viral subtype and examine outcomes following early ART initiation. We will investigate patient-reported outcomes, well-being, and experiences of, knowledge of, and attitudes to HIV preventions, including PrEP. We will analyse qualitative data thematically and triangulate quantitative and qualitative findings. As patient public involvement is central to this work, we have convened a community advisory board (CAB) comprising people living with HIV.Ethics and dissemination All respective research ethics committees have approval for data to contribute to international collaborations. Written informed consent is required to take part. A dissemination strategy will be developed in collaboration with CAB and the scientific committee. It will include peer-reviewed publications, conference presentations and accessible summaries of findings on the study’s website, social media and via community organisations.

Summary: Background: Broad direct-acting antiviral (DAA) access may reduce hepatitis C virus (HCV) incidence through a “treatment as prevention” (TasP) effect. We assessed changes in primary HCV incidence following DAA access among people living with HIV (PLHIV). Methods: We used pooled individual-level data from six cohorts from the International Collaboration on Hepatitis C Elimination in HIV Cohorts (InCHEHC). Follow-up started from the first recorded negative HCV antibody test date and ended at last negative antibody test or estimated infection date. Follow-up was restricted to 2010–2019. We used segmented Poisson regression to model trends across pre-, limited- (i.e., restrictions on access) and broad-DAA access periods. Findings: Overall, 45,942 participants had at least one HCV antibody negative result and follow-up between 2010 and 2019. We observed 2042 incident HCV infections over 248,189 person-years (PY). Pooled incidence decreased from 0.91 per 100 PY in 2015 to 0.41 per 100 PY in 2019. Compared to the average pre-DAA period incidence (0.90 per 100 PY), average incidence was similar during the limited-DAA access period (Incidence rate ratio [IRR] = 0.98; 95%CI = 0.87, 1.11), and 52% lower during the broad-DAA access period (IRR = 0.48; 95%CI = 0.42, 0.52). The average annual decline in HCV incidence was 2% in the pre-DAA period; an additional 9% annual decline in incidence was observed during the limited-DAA access period (IRR = 0.91; 95%CI = 0.82, 1.00) and a further 20% decline in the broad-DAA access period (IRR = 0.80, 95%CI = 0.73, 0.89). Interpretation: Our findings suggest that broad DAA access has a TasP effect on primary HCV incidence among PLHIV. Based on the initial years of DAA availability, the countries in the InCHEHC collaboration are on track to meet the World Health Organization's 80% HCV incidence reduction target for PLHIV by 2030. Funding: This study was funded by the Australian Government National Health and Medical Research Council (Grant number GNT1132902).

IntroductionIn the 2022 multicountry mpox (formerly named monkeypox) outbreak, several countries offered primary preventive vaccination (PPV) to people at higher risk for infection. We study vaccine acceptance and its determinants, to target and tailor public health (communication-) strategies in the context of limited vaccine supply in the Netherlands.MethodsOnline survey in a convenience sample of gay, bisexual and other men who have sex with men, including transgender persons (22/07-05/09/2022, the Netherlands). We assessed determinants for being (un)willing to accept vaccination. We used multivariable multinominal regression and logistic regression analyses, calculating adjusted odds ratios (aOR) and 95 percent confidence-intervals. An open question asked for campaigning and procedural recommendations.ResultsOf respondents, 81.5% (n = 1,512/1,856) were willing to accept vaccination; this was 85.2% (799/938) in vaccination-eligible people and 77.7% (713/918) in those non-eligible. Determinants for non-acceptance included: urbanization (rural: aOR:2.2;1.2–3.7; low-urban: aOR:2.4;1.4–3.9; vs. high-urban), not knowing mpox-vaccinated persons (aOR:2.4;1.6–3.4), and lack of connection to gay/queer-community (aOR:2.0;1.5–2.7). Beliefs associated with acceptance were: perception of higher risk/severity of mpox, higher protection motivation, positive outcome expectations post vaccination, and perceived positive social norms regarding vaccination. Respondents recommended better accessible communication, delivered regularly and stigma-free, with facts on mpox, vaccination and procedures, and other preventive options. Also, they recommended, “vaccine provision also at non-clinic settings, discrete/anonymous options, self-registration” to be vaccinated and other inclusive vaccine-offers (e.g., also accessible to people not in existing patient-registries).ConclusionIn the public health response to the mpox outbreak, key is a broad and equitable access to information, and to low-threshold vaccination options for those at highest risk. Communication should be uniform and transparent and tailored to beliefs, and include other preventive options. Mpox vaccine willingness was high. Public health efforts may be strengthened in less urbanized areas and reach out to those who lack relevant (community) social network influences.

Summary: Background: Indicator-condition (IC) guided HIV testing is a feasible and cost-effective strategy to identify undiagnosed people living with HIV (PLHIV), but remains insufficiently implemented. We aimed to promote IC-guided HIV testing in seven ICs. Methods: Relevant departments in five hospitals of the Amsterdam region participated. HIV testing among adult patients without known HIV infection but with an IC was assessed using electronic health records during pre-intervention (January 2015–June 2020) and intervention (July 2020–June 2021) periods. The multifaceted intervention included audit and feedback. The primary endpoint was HIV testing ≤3 months before or after IC diagnosis and the effect of the intervention was evaluated using segmented Poisson regression. Findings: Data from 7986 patients were included, of whom 6730 (84·3%) were diagnosed with an IC in the pre-intervention period and 1256 (15·7%) in the intervention period. The proportion HIV tested ≤3 months before or after IC diagnosis increased from 36.8% to 47.0% (adjusted risk ratio [RR]= 1.16, 95% CI=1.03–1.30, p=0.02). For individual ICs, we observed significant increases in HIV testing among patients with cervical cancer or intraepithelial neoplasia grade 3 (adjusted RR=3.62, 95% CI=1.93–6.79) and peripheral neuropathy (adjusted RR=2.27 95% CI=1.48–3.49), but not the other ICs. Eighteen of 3068 tested patients were HIV positive (0.6%). Interpretation: Overall IC-guided testing improved after the intervention, but not for all ICs. Variations in effect by IC may have been due to variations in implemented developments, but the effect of separate elements could not be assessed.

We assessed the predictive capacity of the HCV-MOSAIC risk score, originally developed for primary early HCV infection, as a screening tool for HCV reinfection in 103 men who have sex with men (MSM) with HIV using data from the MOSAIC cohort, including MSM with HIV/HCV-coinfection who became reinfected (cases, n = 27) or not (controls, n = 76) during follow-up. The overall predictive capacity of the score was assessed using the area under the receiver operating characteristic (AUROC) curve. The effects of covariates on the receiver operating characteristic (ROC) curve were assessed using parametric ROC regression. The score cut-off validated for primary early infection (≥2.0) was used, from which the sensitivity and specificity were calculated. The AUROC was 0.74 (95% confidence interval (CI) = 0.63–0.84). Group sex significantly increased the predictive capacity. Using the validated cut-off, sensitivity was 70.4% (95%CI = 49.8–86.2%) and specificity was 59.2% (95%CI: 47.3–70.4%). External validation from a cohort of 25 cases and 111 controls, all MSM with HIV, resulted in a sensitivity of 44.0% (95%CI = 24.4–65.1) and specificity of 71.2% (95%CI = 61.8–79.4). The HCV-MOSAIC risk score may be useful for identifying individuals at risk of HCV reinfection. In sexual health or HIV-care settings, this score could help guide HCV-RNA testing in MSM with a prior HCV infection.

Medicine - Abstract
BackgroundVaccines can be less immunogenic in people living with HIV (PLWH), but for SARS-CoV-2 vaccinations this is unknown. In this study we set out to investigate, for the vaccines currently approved in the Netherlands, the immunogenicity and reactogenicity of SARS-CoV-2 vaccinations in PLWH.Methods and findingsWe conducted a prospective cohort study to examine the immunogenicity of BNT162b2, mRNA-1273, ChAdOx1-S, and Ad26.COV2.S vaccines in adult PLWH without prior COVID-19, and compared to HIV-negative controls. The primary endpoint was the anti-spike SARS-CoV-2 IgG response after mRNA vaccination. Secondary endpoints included the serological response after vector vaccination, anti-SARS-CoV-2 T-cell response, and reactogenicity. Between 14 February and 7 September 2021, 1,154 PLWH (median age 53 [IQR 44-60] years, 85.5% male) and 440 controls (median age 43 [IQR 33-53] years, 28.6% male) were included in the final analysis. Of the PLWH, 884 received BNT162b2, 100 received mRNA-1273, 150 received ChAdOx1-S, and 20 received Ad26.COV2.S. In the group of PLWH, 99% were on antiretroviral therapy, 97.7% were virally suppressed, and the median CD4+ T-cell count was 710 cells/μL (IQR 520-913). Of the controls, 247 received mRNA-1273, 94 received BNT162b2, 26 received ChAdOx1-S, and 73 received Ad26.COV2.S. After mRNA vaccination, geometric mean antibody concentration was 1,418 BAU/mL in PLWH (95% CI 1322-1523), and after adjustment for age, sex, and vaccine type, HIV status remained associated with a decreased response (0.607, 95% CI 0.508-0.725, p < 0.001). All controls receiving an mRNA vaccine had an adequate response, defined as >300 BAU/mL, whilst in PLWH this response rate was 93.6%. In PLWH vaccinated with mRNA-based vaccines, higher antibody responses were predicted by CD4+ T-cell count 250-500 cells/μL (2.845, 95% CI 1.876-4.314, p < 0.001) or >500 cells/μL (2.936, 95% CI 1.961-4.394, p < 0.001), whilst a viral load > 50 copies/mL was associated with a reduced response (0.454, 95% CI 0.286-0.720, p = 0.001). Increased IFN-γ, CD4+ T-cell, and CD8+ T-cell responses were observed after stimulation with SARS-CoV-2 spike peptides in ELISpot and activation-induced marker assays, comparable to controls. Reactogenicity was generally mild, without vaccine-related serious adverse events. Due to the control of vaccine provision by the Dutch National Institute for Public Health and the Environment, there were some differences between vaccine groups in the age, sex, and CD4+ T-cell counts of recipients.ConclusionsAfter vaccination with BNT162b2 or mRNA-1273, anti-spike SARS-CoV-2 antibody levels were reduced in PLWH compared to HIV-negative controls. To reach and maintain the same serological responses as HIV-negative controls, additional vaccinations are probably required.Trial registrationThe trial was registered in the Netherlands Trial Register (NL9214). https://www.trialregister.nl/trial/9214.

Abstract Background Late presentation remains a key barrier towards controlling the HIV epidemic. Indicator conditions (ICs) are those that are AIDS-defining, associated with a prevalence of undiagnosed HIV > 0.1%, or whose clinical management would be impeded if an HIV infection were undiagnosed. IC-guided HIV testing is an effective strategy in identifying undiagnosed HIV, but opportunities for earlier HIV diagnosis through IC-guided testing are being missed. We present a protocol for an interventional study to improve awareness of IC-guided testing and increase HIV testing in patients presenting with ICs in a hospital setting. Methods We designed a multicentre interventional study to be implemented at five hospitals in the region of Amsterdam, the Netherlands. Seven ICs were selected for which HIV test ratios (proportion of patients with an IC tested for HIV) will be measured: tuberculosis, cervical/vulvar cancer or high-grade cervical/vulvar dysplasia, malignant lymphoma, hepatitis B and C, and peripheral neuropathy. Prior to the intervention, a baseline assessment of HIV test ratios across ICs will be performed in eligible patients (IC diagnosed January 2015 through May 2020, ≥18 years, not known HIV positive) and an assessment of barriers and facilitators for HIV testing amongst relevant specialties will be conducted using qualitative (interviews) and quantitative methods (questionnaires). The intervention phase will consist of an educational intervention, including presentation of baseline results as competitive graphical audit and feedback combined with discussion on implementation and opportunities for improvement. The effect of the intervention will be assessed by comparing HIV test ratios of the pre-intervention and post-intervention periods. The primary endpoint is the HIV test ratio within ±3 months of IC diagnosis. Secondary endpoints are the HIV test ratio within ±6 months of diagnosis, ratio ever tested for HIV, HIV positivity percentage, proportion of late presenters and proportion with known HIV status prior to initiating treatment for their IC. Discussion This protocol presents a strategy aimed at increasing awareness of the benefits of IC-guided testing and increasing HIV testing in patients presenting with ICs in hospital settings to identify undiagnosed HIV in Amsterdam, the Netherlands.

Medicine ,Science - Abstract
Hepatitis C virus (HCV) elimination among men who have sex with men (MSM) is unlikely to be feasible without effective behavioural interventions. We developed a multilevel intervention to reduce HCV transmission among MSM in Amsterdam. The intervention includes a toolbox to facilitate risk reduction among MSM and support health care professionals in risk reduction counselling. To assess the use of the toolbox and its impact on behavior, we conducted a mixed-methods study. We collected data through online questionnaires (n = 49), and in-depth interviews with MSM at risk of HCV (n = 15) and health care professionals (n = 7). We found that the toolbox has been well received by MSM, increased awareness of HCV risks and has facilitated preventive behaviours and risk-reduction communication with peers. Professionals reported the toolbox to be a useful aid for discussions about HCV risk and risk reduction strategies with their clients.

Background: Mortality rates are high among hospitalized patients with COVID-19, especially in those intubated on the ICU. Insight in pathways associated with unfavourable outcome may lead to new treatment strategies. Methods: We performed a prospective cohort study of patients with COVID-19 admitted to general ward or ICU who underwent serial blood sampling. To provide insight in the pathways involved in disease progression, associations were estimated between outcome risk and serial measurements of 64 biomarkers in potential important pathways of COVID-19 infection (inflammation, tissue damage, complement system, coagulation and fibrinolysis) using joint models combining Cox regression and linear mixed-effects models. For patients admitted to the general ward, the primary outcome was admission to the ICU or mortality (unfavourable outcome). For patients admitted to the ICU, the primary outcome was 12-week mortality. Findings: A total of 219 patients were included: 136 (62%) on the ward and 119 patients (54%) on the ICU; 36 patients (26%) were included in both cohorts because they were transferred from general ward to ICU. On the general ward, 54 of 136 patients (40%) had an unfavourable outcome and 31 (23%) patients died. On the ICU, 54 out of 119 patients (45%) died. Unfavourable outcome on the general ward was associated with changes in concentrations of IL-6, IL-8, IL-10, soluble Receptor for Advanced Glycation End Products (sRAGE), vascular cell adhesion molecule 1 (VCAM-1) and Pentraxin-3. Death on the ICU was associated with changes in IL-6, IL-8, IL-10, sRAGE, VCAM-1, Pentraxin-3, urokinase-type plasminogen activator receptor, IL-1-receptor antagonist, CD14, procalcitonin, tumor necrosis factor alfa, tissue factor, complement component 5a, Growth arrest–specific 6, angiopoietin 2, and lactoferrin. Pathway analysis showed that unfavourable outcome on the ward was mainly driven by chemotaxis and interleukin production, whereas death on ICU was associated with a variety of pathways including chemotaxis, cell-cell adhesion, innate host response mechanisms, including the complement system, viral life cycle regulation, angiogenesis, wound healing and response to corticosteroids. Interpretation: Clinical deterioration in patients with severe COVID-19 involves multiple pathways, including chemotaxis and interleukin production, but also endothelial dysfunction, the complement system, and immunothrombosis. Prognostic markers showed considerable overlap between general ward and ICU patients, but we identified distinct differences between groups that should be considered in the development and timing of interventional therapies in COVID-19.

Summary: Background: The AGEhIV cohort study is a prospective cohort study evaluating the occurrence of age-related comorbidities in people living with and without HIV. We previously reported a lower forced vital capacity (FVC) in HIV-positive compared with HIV-negative participants in those without heavy smoking exposure at time of enrolment in the AGEhIV cohort study. In this study we evaluate longitudinal changes in spirometry indices in the same AGEhIV cohort accounting for smoking behaviour and other risk factors. Methods: We obtained pre-bronchodilator spirometry measurements in AGEhIV cohort participants during biennial visits over a median of 5·9 years (IQR 5·7–6·0). Adjusted declines in forced expiratory volume in 1 s (FEV1), FVC, and FEV1/FVC ratio were modelled using linear mixed-effects models and compared by HIV status and smoking status. To evaluate whether changes in spirometry measurements could be driven by increased levels of chronic inflammation, we assessed associations between rates of FEV1 and FVC decline and CD4 and CD8 T-cell counts, and plasma concentrations of C-reactive protein (CRP), interleukin 6, soluble CD14, soluble CD163, and intestinal fatty-acid-binding protein in separate models. The study is registered at ClinicalTrials.gov, NCT01466582. Findings: 500 HIV-positive and 481 HIV-negative participants were included with spirometry data from Oct 29, 2010, to Aug 14, 2018. HIV-positive participants were virally suppressed (

ObjectivesRecent studies have reported disproportionate weight gain associated with integrase strand transfer inhibitor (INSTI) initiation in antiretroviral therapy(ART)-naive people with HIV (PWH), particularly among black women. We investigated if HIV-positive AGEhIV participants with suppressed viremia switching to INSTI-containing ART experienced more weight gain compared to HIV-positive virally-suppressed non-switching and HIV-negative controls.MethodsIn the AGEhIV cohort, standardized weight measurements were performed biennially. Participants switching to INSTI-containing ART were 1:2:2 propensity score-matched with controls by age, gender, ethnicity and body mass index. Mean weight changes and proportions experiencing >5% or >10% weight gain were compared between study-groups using linear mixed-effects models and logistic regression, respectively.Results121 INSTI-switching participants and 242 participants from each of the control groups were selected. Across groups, median age was 53-55 years, 83-91% were male and 88-93% white. Mean weight change after switch among INSTI-switching participants was +0.14 kg/year (95%CI -0.25, +0.54) and similar among HIV-positive [+0.13 kg/year (95%CI +0.07, +0.33; P = .9)] and HIV-negative [+0.18 kg/year (95%CI 0.00, +0.37; P = .9)] controls. Weight gain >5% occurred in 28 (23.1%) INSTI-switching, 38 HIV-positive (15.7%, P = .085) and 32 HIV-negative controls (13.2%, P = .018). Weight gain >10% was rare.ConclusionsSwitching to INSTI-containing ART in our cohort of predominantly white men on long-term ART was not associated with greater mean weight gain, but >5% weight gain was more common than in controls. These results suggest that not all, but only certain, PWH may be particularly prone to gain a clinically significant amount of weight as a result of switching to INSTI.

Background The Netherlands has a low hepatitis C virus (HCV) prevalence, estimated at 0.16%. Previous studies have shown that up to 30% of the diagnosed HCV population in the Netherlands has been lost to follow-up (LTFU). Retrieval of these patients could halt progression of liver disease in infected patients, reduce the number of infected individuals and limit HCV transmission. Several regional Dutch retrieval projects have already been executed, which demonstrated that retrieval is feasible. Therefore, we initiated a nationwide retrieval project, aiming to achieve microelimination in previously diagnosed but LTFU patients with chronic HCV through retrieval.Methods Laboratory records will be used to identify possible patients with chronic hepatitis C, defined as either a positive most recent HCV RNA or positive HCV antibodies without known RNA result. Reviewing patient records and obtaining current contact information from municipality databases will identify LTFU patients who are eligible for retrieval. These patients will be invited for outpatient clinic care. The primary outcome of the study is the total number of LTFU patients who have been successfully linked to care.Discussion Hepatitis C ELimination In the NEtherlands (CELINE) is within the remit of WHO elimination targets and the Dutch National Hepatitis Plan. The methodology of CELINE is based on previously conducted regional retrieval projects and is designed to overcome some of their limitations. After ethical approval was obtained in 2018, the first centre initiated retrieval in 2018 and the project is expected to finish in 2021.Trial registration number NCT04208035.

Medicine ,Science - Abstract
To facilitate HCV diagnosis, we developed an HCV-RNA testing service, which involved home-sampled dried blood spots (DBS). The main objective of this study was to evaluate the feasibility of self-sampling at home. Furthermore, to optimise the processing of DBS samples for RNA detection, we evaluated two elution buffers: phosphate-buffered saline (PBS) and L6-buffer. 27 HCV-RNA and 12 HIV-1 RNA positive patients were included. Laboratory spotted DBS (LabDBS) were made by a technician from blood samples drawn at inclusion. Patients received a DBS home-sampling kit and were requested to return their self-sampled DBS (ssDBS) by mail. We compared the RNA load of PBS and L6-eluted labDBS, and of L6-eluted ssDBS, L6-eluted labDBS and plasma. LabDBS load measurements were repeated after 7-13 and 14-21 days to evaluate RNA stability. All 39 plasma samples provided quantifiable RNA loads. In 1/39 labDBS sample, RNA could not be detected (plasma HCV load: 2.98 log10 IU/ml). L6-eluted samples gave a 0.7 log10 and 0.6 log10 higher viral load for HCV and HIV-1 respectively, compared to PBS-eluted samples. Strong correlations were found between labDBS and ssDBS HCV RNA (r = 0.833; mean difference 0.3 log10 IU/mL) and HIV-1 RNA results (r = 0.857; mean difference 0.1 log10 copies/mL). Correlations between labDBS and plasma values were high for HCV (r = 0.958) and HIV-1 (r = 0.844). RNA loads in DBS remained stable over 21 days. Our study demonstrates that self-sampling dried blood spots at home is a feasible strategy for the detection of HCV and HIV-1 RNA. This could facilitate one-step diagnostics and treatment monitoring in communities with high HCV prevalence.

OBJECTIVE Assessing whether the previously reported association between abacavir (ABC) and cardiovascular disease (CVD) remained amongst contemporarily treated people living with HIV (PLWH). DESIGN Multinational cohort collaboration. METHODS RESPOND participants were followed from latest of 01/01/2012 or cohort enrolment until the first of a CVD event (myocardial infarction [MI], stroke, invasive cardiovascular procedure [ICP]), last follow-up or 31/12/2019. Logistic regression examined odds of starting ABC by 5-year CVD or chronic kidney disease (CKD) D:A:D risk score. We assessed associations between recent ABC use (use within past six months) and risk of CVD with negative binomial regression models, adjusted for potential confounders. RESULTS Of 29,340 individuals, 34% recently used ABC. Compared to those at low estimated CVD and CKD risks, the odds of starting ABC were significantly higher among individuals at high CKD risk (odds ratio 1.12 [95% confidence interval, 1.04-1.21]) and significantly lower for individuals at moderate, high or very high CVD risk (0.80 [0.72-0.88], 0.75 [0.64-0.87], 0.71 [0.56-0.90], respectively). During 6.2 years median follow-up (interquartile range; 3.87-7.52), there were 748 CVD events (incidence rate [IR] 4.7/1000 persons-years of follow up [4.3-5.0]). The adjusted CVD IR ratio was higher for individuals with recent ABC use (1.40 [1.20-1.64]) compared to individuals without, consistent across sensitivity analyses. The association did not differ according to estimated CVD (interaction p = 0.56) or CKD (p = 0.98) risk strata. CONCLUSION Within RESPOND's contemporarily treated population, a significant association between CVD incidence and recent ABC use was confirmed and not explained by preferential ABC use in individuals at increased CVD or CKD risk.

BackgroundThe COVIH study is a prospective coronavirus disease 2019 (COVID-19) vaccination study in 1154 people with HIV (PWH), of whom 14% showed reduced antibody levels after primary vaccination. We evaluated whether an additional vaccination boosts immune responses in these hyporesponders.MethodsThe primary end point was the increase in antibodies 28 days after additional mRNA-1273 vaccination. Secondary end points included neutralizing antibodies, S-specific T-cell and B-cell responses, and reactogenicity.ResultsOf the 66 participants, 40 previously received 2 doses ChAdOx1-S, 22 received 2 doses BNT162b2, and 4 received a single dose Ad26.COV2.S. The median age was 63 years (interquartile range [IQR], 60–66), 86% were male, and median CD4+ T-cell count was 650/μL (IQR, 423–941). The mean S1-specific antibody level increased from 35 binding antibody units (BAU)/mL (95% confidence interval [CI], 24–46) to 4317 BAU/mL (95% CI, 3275–5360) (P < .0001). Of all participants, 97% showed an adequate response and the 45 antibody-negative participants all seroconverted. A significant increase in the proportion of PWH with ancestral S-specific CD4+ T cells (P = .04) and S-specific B cells (P = .02) was observed.ConclusionsAn additional mRNA-1273 vaccination induced a robust serological response in 97% of PWH with a hyporesponse after primary vaccination.Clinical Trials Registration.

BACKGROUND Although associations between older antiretroviral drug classes and cardiovascular disease in people living with HIV are well described, there is a paucity of data regarding a possible association with integrase strand-transfer inhibitors (INSTIs). We investigated whether exposure to INSTIs was associated with an increased incidence of cardiovascular disease. METHODS RESPOND is a prospective, multicentre, collaboration study between 17 pre-existing European and Australian cohorts and includes more than 32 000 adults living with HIV in clinical care after Jan 1, 2012. Individuals were eligible for inclusion in these analyses if they were older than 18 years, had CD4 cell counts and HIV viral load measurements in the 12 months before or within 3 months after baseline (latest of cohort enrolment or Jan 1, 2012), and had no exposure to INSTIs before baseline. These individuals were subsequently followed up to the earliest of the first cardiovascular disease event (ie, myocardial infarction, stroke, or invasive cardiovascular procedure), last follow-up, or Dec 31, 2019. We used multivariable negative binomial regression to assess associations between cardiovascular disease and INSTI exposure (0 months [no exposure] vs >0 to 6 months, >6 to 12 months, >12 to 24 months, >24 to 36 months, and >36 months), adjusted for cardiovascular risk factors. RESPOND is registered with ClinicalTrials.gov, NCT04090151, and is ongoing. FINDINGS 29 340 people living with HIV were included in these analyses, of whom 7478 (25·5%) were female, 21 818 (74·4%) were male, and 44 (24 to 36 months of exposure). Compared with those with no INSTI exposure, the risk of cardiovascular disease was increased in the first 24 months of INSTI exposure and thereafter decreased to levels similar to those never exposed (>0 to 6 months of exposure: adjusted incidence rate ratio of 1·85 [1·44-2·39]; >6 to 12 months of exposure: 1·19 [0·84-1·68]; >12 to 24 months of exposure: 1·46 [1·13-1·88]; >24 to 36 months of exposure: 0·89 [0·62-1·29]; and >36 months of exposure: 0·96 [0·69-1·33]; p

Background Within the ongoing AGEhIV Cohort Study in Amsterdam, we prospectively compared the incidence of and risk factors for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection between human immunodeficiency virus (HIV)–positive and HIV-negative participants. Moreover, we compared SARS-CoV-2 nucleocapsid antibody levels between participants with incident infection from both groups. Methods Starting in September 2020, consenting HIV-positive and HIV-negative participants were assessed every 6 months for incident SARS-CoV-2 infection, using combined immunoglobulin (Ig) A/IgM/IgG SARS-CoV-2 nucleocapsid antibody assay. Cumulative incidence of SARS-CoV-2 infection and associated risk factors were assessed from 27 February 2020 through 30 April 2021, using complementary log-log regression. In those with incident SARS-CoV-2 infection, nucleocapsid (N) antibody levels were compared between groups using linear regression. Results The study included 241 HIV-positive (99.2% virally suppressed) and 326 HIV-negative AGEhIV participants. The cumulative SARS-CoV-2 incidence by April 2021 was 13.4% and 11.6% in HIV-positive and HIV-negative participants, respectively (P = .61). Younger age and African origin were independently associated with incident infection. In those with incident infection, only self-reported fever, but not HIV status, was associated with higher N antibody levels. Conclusions HIV-positive individuals with suppressed viremia and adequate CD4 cell counts had similar risk of SARS-CoV-2 acquisition and similar SARS-CoV-2 N antibody levels after infection compared with a comparable HIV-negative cohort. Clinical Trial Registration NCT01466582.

In the Netherlands, hepatitis C virus (HCV) transmission occurs primarily in men who have sex with men (MSM). By early diagnosis and immediate treatment of acute HCV infections, HCV micro-elimination in MSM is within reach. In cooperation with the community affected, we developed an online HCV-RNA home-based self-sampling test service. This service combined online HCV self-risk assessment with the possibility to test anonymously for HCV-RNA. The service was available in the Netherlands from February 2018 till December 2020 and was promoted online on various dating sites and offline by community volunteers. Using website user data, test results and an online post-test user survey, we evaluated the service and user experiences. The website page with information about testing was visited by 3401 unique users, of whom 2250 used the HCV-risk assessment tool, 152 individuals purchased 194 HCV-RNA tests, and 104 tests were used, of which 101 gave a conclusive result. The target population of MSM at risk was successfully reached with 44.1% of users receiving the advice to test. The test service had a satisfactory uptake (6.8%, 152/2250), a very high HCV-RNA positivity rate (10.9%, 11/101) and was considered acceptable and easy to use by most MSM. We demonstrate that an HCV-RNA home-based self-sampling test service is successful in diagnosing HCV infections among MSM. This service could be a valuable addition to existing sexual healthcare services as it may reach men who are otherwise not tested.

OBJECTIVE: To describe hepatitis C virus (HCV)-viremia prevalence and barriers to direct-acting antiviral (DAA) treatment during unrestricted access to DAA in a nationwide cohort of people living with HIV (PLWH).DESIGN: Retrospective analysis of prospectively-collected data.METHODS: We calculated yearly HCV-viremia prevalence as proportion of HCV RNA-positive individuals ever HCV-tested. We then included HCV-viremic individuals with ≥1 visit during the era of universal DAA-access (database lock=31 December 2018). Based on their last visit, individuals were grouped as DAA-treated or -untreated. Variables associated with lack of DAA-treatment were assessed using targeted maximum likelihood estimation. In November 2020, physicians of DAA-untreated individuals completed a questionnaire on barriers to DAA-uptake and onward HCV-transmission risk.RESULTS: Among 25,196 PLWH, HCV-viremia decreased from 4-5% between 2000-2014 to 0.6% in 2019. Being DAA-untreated was associated with HIV-transmission route other than men who have sex with men, older age, infrequent follow-up, severe alcohol use, detectable HIV-RNA, HCV-genotype 3, and larger hospital size. With universal DAA-access, 72/979 HCV-viremic individuals remained DAA-untreated at their last visit. Of these, 39 were no longer in care, 27 remained DAA-untreated in care, and six initiated DAA since database lock. Most common physician-reported barriers to DAA-uptake were patient refusal (20/72, 28%) and infrequent visit attendance (19/72, 26%). Only one DAA-untreated individual in care was engaging in activities associated with onward HCV-transmission.CONCLUSIONS: Prevalence of HCV-viremic PLWH is low in the Netherlands, coinciding with widespread DAA-uptake. Barriers to DAA-uptake appear mostly patient-related, while HCV-transmission seems unlikely from the few DAA-untreated in care.

IntroductionDespite the availability of pre-exposure prophylaxis (PrEP) and antiretroviral therapy (ART), 21 793 people were newly diagnosed with HIV in Europe in 2019. The Concerted action on seroconversion to AIDS and death in Europe study aims to understand current drivers of the HIV epidemic; factors associated with access to, and uptake of prevention methods and ART initiation; and the experiences, needs and outcomes of people with recently acquired HIV.Methods and analysisThis longitudinal observational study is recruiting participants aged ≥16 years with documented laboratory evidence of HIV seroconversion from clinics in Canada and six European countries. We will analyse data from medical records, self-administered questionnaires, semistructured interviews and participatory photography. We will assess temporal trends in transmitted drug resistance and viral subtype and examine outcomes following early ART initiation. We will investigate patient-reported outcomes, well-being, and experiences of, knowledge of, and attitudes to HIV preventions, including PrEP. We will analyse qualitative data thematically and triangulate quantitative and qualitative findings. As patient public involvement is central to this work, we have convened a community advisory board (CAB) comprising people living with HIV.Ethics and disseminationAll respective research ethics committees have approval for data to contribute to international collaborations. Written informed consent is required to take part. A dissemination strategy will be developed in collaboration with CAB and the scientific committee. It will include peer-reviewed publications, conference presentations and accessible summaries of findings on the study’s website, social media and via community organisations.

Background & Aims: HBV coinfection is common among people living with HIV (PLWH) and is the most important cause of hepatocellular carcinoma (HCC). While risk prediction tools for HCC have been validated in patients with HBV monoinfection, they have not been evaluated in PLWH. Thus, we performed an external validation of PAGE-B in people with HIV/HBV coinfection.Methods: We included data on PLWH from four European cohorts who were positive for HBsAg and did not have HCC before starting tenofovir. We estimated the predictive performance of PAGE-B for HCC occurrence over 15 years in patients receiving tenofovir-containing antiretroviral therapy. Model discrimination was assessed after multiple imputation using Cox regression with the prognostic index as a covariate, and by calculating Harrell's c-index. Calibration was assessed by comparing our cumulative incidence with the PAGE-B derivation study using Kaplan-Meier curves.Results: In total, 2,963 individuals with HIV/HBV coinfection on tenofovir-containing antiretroviral therapy were included. PAGE-B was Conclusions: For individuals with HIV/HBV coinfection, PAGE-B is a valid tool to determine the need for HCC screening. Impact and implications: Chronic HBV infection is the most important cause of hepatocellular carcinoma (HCC) among people living with HIV. Valid risk prediction may enable better targeting of HCC screening efforts to high-risk individuals. We aimed to validate PAGE-B, a risk prediction tool that is based on age, sex, and platelets, in 2,963 individuals with HIV/HBV coinfection who received tenofovir-containing antiretroviral therapy. In the present study, PAGE-B showed good discrimination, adequate calibration, and a cut-off of

Background: People with HIV generally have more ageing-associated comorbidities than those without HIV. We aimed to establish whether the difference in comorbidities and their disease burden changes with ageing. Methods: In this prospective, longitudinal cohort study, we assessed comorbidities commonly associated with ageing every 2 years in 596 HIV-positive and 550 HIV-negative participants. HIV-positive participants were recruited from the HIV outpatient clinic of the Amsterdam University Medical Centres (Amsterdam, Netherlands). HIV-negative participants were recruited from the sexual health clinic and the Amsterdam Cohort Studies at the Public Health Service of Amsterdam (Amsterdam, Netherlands). Inclusion criteria were participants aged 45 years or older and, for HIV-negative participants, a documented HIV-negative antibody test. The mean number of comorbidities present over time was compared between groups by use of Poisson regression, accounting for dropout and death through joint survival models. Mean disability-adjusted life-years (DALYs) accrued during 2-year intervals were compared between groups by use of an exponential hurdle model. Findings: Between Oct 29, 2010, and Oct 9, 2012, participants were enrolled and then prospectively followed up until their last visit before Oct 1, 2018. 1146 participants were followed up for a median 5·9 years (IQR 5·7–6·0), during which 231 participants (20·2%) dropped out: 145 (24·3%) of 596 HIV-positive and 86 (15·6%) of 550 HIV-negative. 38 (3·3%) of 1146 participants died: 31 (5·2%) of 596 HIV-positive and seven (1·3%) of 550 HIV-negative. 24 HIV-positive and two HIV-negative participants died from ageing-associated comorbidities. 15 HIV-positive participants versus one HIV-negative participant died from non-AIDS malignancies. At inclusion, mean number of comorbidities was higher in HIV-positive participants (0·65) than in HIV-negative participants (0·32; pinteraction=0·78). Number of comorbidities was associated with an increased risk of death (hazard ratio 3·33 per additional comorbidity, 95% CI 2·27–4·88; pinteraction=0·0045). This difference was reduced when deaths were excluded in establishing DALYs (0·127, 0·083–0·171 vs 0·066, 0·005–0·127; p interaction =0·11). Interpretation: The larger comorbidity prevalence in HIV-positive participants aged 50–55 years on effective antiretroviral treatment than in HIV-negative participants increased similarly as participants aged and was associated with an increased risk of death, particularly of non-AIDS malignancies. Our findings reinforce the need for strategies to optimise prevention, screening, and early intervention.

Background: Incidence of anal cancer is high in people living with HIV, particularly in men who have sex with men (MSM). Screening for and treatment of precursor lesions might prevent progression to anal cancer in people living with HIV. We examined trends in incidence of and mortality after anal cancer diagnosis in people living with HIV, including the effect of screening from 2007 onwards, in the Netherlands. Methods: In this observational cohort study, we analysed data from the ongoing open nationwide Dutch AIDS Therapy Evaluation in the Netherlands (ATHENA) cohort. We included all consenting adults living with HIV and identified all primary anal squamous cell carcinoma. We reported temporal trends in incident anal cancer cases from Jan 1, 1996, to Dec 31, 2020, and all-cause and anal cancer-related mortality in individuals diagnosed with anal cancer. Multivariable Poisson regression was used to explore risk factors for incident anal cancer and multivariable Cox regression was used to explore risk factors for anal cancer-related mortality. Findings: Among 28 175 individuals in HIV care (59·7% MSM), 227 primary anal cancer cases were diagnosed. Despite the increasing average age of the cohort, crude incidence rates of anal cancer in MSM declined slowly over time, from 107·0 (95% CI 75·7–147·0) per 100 000 person-years in 1996–2005 to 93·7 (75·3–115·0) per 100 000 person-years in 2013–20 (p=0·49). Crude incidence rates in men who do not have sex with men (non-MSM) and women were generally lower than in MSM, but increased slightly over time, from 51·08 (95% CI 20·54–105·25) to 67·82 (40·83–105·91; p=0·52) per 100 000 person-years in non-MSM and from 8·09 (0·20–45·06) to 24·95 (10·03–51·40; p=0·29) per 100 000 person-years in women. The age-adjusted incidence rate in MSM in 2013–20 was significantly lower (rate ratio 0·62 [95% CI 0·41–0·92]) compared with in 1996–2005. Changes in risk factors (less smoking, cumulative exposure to CD4 count of 1000 copies per mL) mostly explained the decrease in anal cancer risk over time in MSM. 3866 (23·0%) of 16 819 MSM participated in anal cancer screening at least once. TNM tumour staging was more favourable (Cochrane-Armitage test for trend p=0·033) in individuals diagnosed during screening. Crude anal cancer-associated 5-year mortality in people living with HIV decreased from 30·4% (1996–2005) to 18·3% (2013–20; odds ratio 0·48; p=0·070). Anal cancer-related mortality was 3·7% (95% CI 0·5–23·5) in all men who had been screened and 24·0% (95% CI 18·1–31·3) in men who had not been screened (p=0·023). In men, screening participation (hazard ratio [HR] 0·31, p=0·051) and cumulative exposure to CD4 counts of less than 200 cells per μL (HR 1·11 per year; p=0·0022) were independently associated with anal cancer-related mortality. Interpretation: As anal cancer incidence is slowly declining in MSM but not in non-MSM and women, health-care professionals should not focus only on MSM for anal cancer prevention. Men diagnosed with anal cancer during screening had improved survival, probably because they were diagnosed at an earlier disease stage. Next to preventing anal cancer, these data are an important justification to screen those most at risk of anal cancer. Funding: None.

BACKGROUND There are limited data on end-stage liver disease (ESLD) and mortality in people with HIV (PWH) coinfected with both hepatitis B virus (HBV) and hepatitis C virus (HCV). METHODS All PWH aged greater than 18 under follow-up in EuroSIDA positive for HBsAg (HBV), and/or HCVRNA+, were followed from baseline (latest of 1 January 2001, EuroSIDA recruitment, known HBV/HCV status) to ESLD, death, last visit, or 31 December 2020. Follow-up while HCVRNA- was excluded. In two separate models, Poisson regression compared three groups updated over time; HIV/HBV, HIV/HCV, and HIV/HBV/HCV. RESULTS Among 5733 included individuals, 4476 (78.1%) had HIV/HCV, 953 (16.6%) had HIV/HBV and 304 (5.3%) had HIV/HBV/HCV. In total, 289 (5%) developed ESLD during 34 178 person-years of follow-up (PYFU), incidence 8.5/1000 PYFU [95% confidence interval (CI) 7.5-9.4] and 707 deaths occurred during 34671 PYFU (incidence 20.4/1000 PYFU; 95% CI 18.9-21.9). After adjustment, compared with those with HIV/HCV, persons with HIV/HBV had significantly lower rates of ESLD [adjusted incidence rate ratio (aIRR) 0.53; 95% CI 0.34-0.81]. Those with HIV/HBV/HCV had marginally significantly higher rates of ESLD (aIRR 1.49; 95% CI 0.98-2.26). Those under follow-up in 2014 or later had significantly lower rates of ESLD compared with 2007-2013 (aIRR 0.65; 95% CI 0.47-0.89). Differences in ESLD between the three groups were most pronounced in those aged at least 40. After adjustment, there were no significant differences in all-cause mortality across the three groups. CONCLUSION HIV/HBV-coinfected individuals had lower rates of ESLD and HIV/HBV/HCV had higher rates of ESLD compared with those with HIV/HCV, especially in those aged more than 40. ESLD decreased over time across all groups. CLINICALTRIALSGOV IDENTIFIER NCT02699736.

The introduction of clotting factor concentrates has substantially improved the lives of people with clotting factor deficiencies. Unfortunately, the transmission of blood-borne viral infections through these plasma-derived products led to a huge epidemic of human immunodeficiency virus and viral hepatitis in people with haemophilia (PWH). In a significant proportion of PWH exposed to these viruses, the ensuing decades-long chronic infection resulted in excess morbidity and mortality. Fortunately, developments in the safety of blood products, as well as vaccination and highly effective antiviral treatments have improved the prospects of PWH. The present article reviews the background of the viral hepatitis epidemic in PWH, the natural history of hepatitis B and C infections and their long-term management.

- Abstract
IntroductionIn the global monkeypox outbreak primary preventive vaccination is offered to people at higher risk for infection. We study vaccine acceptance and its determinants, to target and tailor public health (communication-)strategies in the context of limited vaccine supply in the Netherlands. Methods. Online survey in a convenience sample of gay, bisexual and other men who have sex with men, including transgender persons (22/07-05/09/2022, the Netherlands). We assessed determinants (sociodemographic, social environment, medical, and behavioral factors, and beliefs) for being (un)willing to accept vaccination. We used multivariable multinominal regression and logistic regression analyses, calculating adjusted odds ratios (aOR) and 95 percent confidence-intervals. An open question asked for campaigning and procedural recommendations.ResultsOf respondents, 81.5% (n=1,512/1,856) were willing to accept vaccination; this was 85.2% (799/938) in vaccination-eligible people (HIV-PrEP use, living with HIV, STI, or >3 partners) and 77.7% (713/918) in those non-eligible. Determinants for non-acceptance included: urbanization (rural: aOR:2.2;1.2-3.7; low-urban: aOR:2.4;1.4-3.9; versus high-urban), not knowing monkeypox-vaccinated persons (aOR:2.4;1.6-3.4), and lack of connection to gay/queer-community (aOR:2.0;1.5-2.7). Beliefs associated with acceptance were perception of higher risk/severity of monkeypox, higher protection motivation, positive outcome expectations post vaccination (effectiveness and side-effects), and perceived positive social norms regarding vaccination of their social network.Respondents recommended more accessible communication, delivered regularly, stigma-free, sex positive and with facts on monkeypox, vaccination benefits and procedures, and explain (other) preventive options. For vaccination, it was recommended to add ‘self-registration’, provision also at non-clinic settings, discrete/anonymous options, and more inclusive strategies to reach people (e.g., those not in existing patient-registries) at high risk for monkeypox.ConclusionIn the public health response to the monkeypox outbreak, key is a broad and equitable access to information, and low-threshold vaccination options for those at highest risk.Communication should be transparent and tailored to beliefs, such as perceived risks of monkeypox, benefits of vaccination, and social norms, and should include other preventive options. Public health efforts may be strengthened in less urbanized areas and reach out to those who lack relevant social network influences.

Background Human immunodeficiency virus (HIV)-positive men who have sex with men (MSM) are at high risk of hepatitis C virus (HCV) reinfection following clearance of HCV, but risk factors specifically for reinfection have never been comprehensively assessed. Methods Using data from a prospective observational cohort study among HIV-positive MSM with an acute HCV infection (MOSAIC), the incidence of HCV reinfection following spontaneous clearance or successful treatment was assessed. A univariable Bayesian exponential survival model was used to identify risk factors associated with HCV reinfection. Results In total, 122 HIV-positive MSM who had a spontaneously cleared or successfully treated HCV infection between 2003 and 2017 were included. During a median follow-up of 1.4 years (interquartile range [IQR] 0.5–3.8), 34 HCV reinfections were observed in 28 patients. The incidence of HCV reinfection was 11.5/100 person-years and among those with reinfection, median time to reinfection was 1.3 years (IQR 0.6–2.7). HCV reinfection was associated with receptive condomless anal intercourse, sharing of sex toys, group sex, anal rinsing before sex, ≥10 casual sex partners in the last 6 months, nadir CD4 cell count Conclusions Incidence of HCV reinfection was high and strongly associated with sexual risk behavior, highlighting the need for interventions to reduce risk behavior and prevent HCV reinfections among HIV-positive MSM.

Background: The AGE hIV cohort study is a prospective cohort study evaluating the occurrence of age-related comorbidities in people living with and without HIV. We previously reported a lower forced vital capacity (FVC) in HIV-positive compared with HIV-negative participants in those without heavy smoking exposure at time of enrolment in the AGE hIV cohort study. In this study we evaluate longitudinal changes in spirometry indices in the same AGE hIV cohort accounting for smoking behaviour and other risk factors. Methods: We obtained pre-bronchodilator spirometry measurements in AGE hIV cohort participants during biennial visits over a median of 5·9 years (IQR 5·7–6·0). Adjusted declines in forced expiratory volume in 1 s (FEV 1), FVC, and FEV 1/FVC ratio were modelled using linear mixed-effects models and compared by HIV status and smoking status. To evaluate whether changes in spirometry measurements could be driven by increased levels of chronic inflammation, we assessed associations between rates of FEV 1 and FVC decline and CD4 and CD8 T-cell counts, and plasma concentrations of C-reactive protein (CRP), interleukin 6, soluble CD14, soluble CD163, and intestinal fatty-acid-binding protein in separate models. The study is registered at ClinicalTrials.gov, NCT01466582. Findings: 500 HIV-positive and 481 HIV-negative participants were included with spirometry data from Oct 29, 2010, to Aug 14, 2018.

There are no comprehensive data on viral hepatitis from Sierra Leone; however, a huge disease burden has been observed in different subpopulations. This review summarizes available data on hepatitis B and C virus (HBV and HCV) prevalence in Sierra Leone and identifies knowledge gaps. Despite the non-uniformity of the studies and the lack of systematic case recording, different reports published in recent decades yielded a hepatitis B prevalence of 8.7% among healthcare workers, 11.3% among pregnant women, 15.2% among blood donors and 16.7% in school-age children. The actual HBV prevalence in the general population was reported as 21.7%; similar to what was reported for people living with human immunodeficiency virus (PLHIV). HCV prevalence is 8% and 7% in male and female blood donors, respectively, 4.1% in PLHIV and 2.0% in school children. There are significant knowledge gaps regarding the prevalence of viral hepatitis B and C in Sierra Leone, despite the high burden reported in a few studies. There are limited programmatic interventions on the control and prevention of viral hepatitis in the country. Therefore, well-structured representative studies should provide a solid understanding of the true prevalence of hepatitis B and C to inform best possible public health measures in Sierra Leone.

- Abstract
BackgroundThe COVIH study is a prospective SARS-CoV-2 vaccination study in people living with HIV (PLWH). Of the 1154 PLWH enrolled, 14% showed a reduced or absent antibody response after a primary vaccination regimen. As the response to an additional vaccination in PLWH with hyporesponse is unknown, we evaluated whether an additional vaccination boosts immune responses in these hyporesponders.MethodsConsenting hyporesponders received an additional 100 µg of mRNA-1273. Hyporesponse was defined as ≤300 spike(S)-specific binding antibody units [BAU]/mL. The primary endpoint was the increase in antibodies 28 days after the additional vaccination. Secondary endpoints were the correlation between patient characteristics and antibody response, levels of neutralizing antibodies, S-specific T-cell and B-cell responses, and reactogenicity.ResultsOf the 75 PLWH enrolled, five were excluded as their antibody level had increased to >300 BAU/mL at baseline, two for a SARS-CoV-2 infection before the primary endpoint evaluation and two were lost to follow-up. Of the 66 remaining participants, 40 previously received ChAdOx1-S, 22 BNT162b2, and four Ad26.COV2.S. The median age was 63 [IQR:60-66], 86% were male, pre-vaccination and nadir CD4+ T-cell counts were 650/μL [IQR:423-941] and 230/μL [IQR:145-345] and 96% had HIV-RNA 300 BAU/mL in 64/66 (97%) with a mean increase of 4282 BAU/mL (95%CI:3241-5323). No patient characteristics correlated with the magnitude of the antibody response nor did the primary vaccination regimen. The additional vaccination significantly increased the proportion of participants with detectable ancestral S-specific B-cells (p=0.016) and CD4+ T-cells (p=0.037).ConclusionAn additional mRNA-1273 vaccination induced a robust serological response in 97% of the PLWH with a hyporesponse after a primary vaccination regimen. This response was observed regardless of the primary vaccination regimen or patient characteristics.

Contains fulltext : 252163.pdf (Publisher’s version ) (Open Access) BACKGROUND & AIMS: The number of chronic hepatitis C virus (HCV)-infected patients who have been lost to follow-up (LTFU) is high and threatens HCV elimination. Micro-elimination focusing on the LTFU population is a promising strategy for low-endemic countries like the Netherlands (HCV prevalence 0.16%). We therefore initiated a nationwide retrieval project in the Netherlands targeting LTFU HCV patients. METHODS: LTFU HCV-infected patients were identified using laboratory and patient records. Subsequently, the Municipal Personal Records database was queried to identify individuals eligible for retrieval, defined as being alive and with a known address in the Netherlands. These individuals were invited for re-evaluation. The primary endpoint was the number of patients successfully re-linked to care. RESULTS: Retrieval was implemented in 45 sites in the Netherlands. Of 20,183 ever-diagnosed patients, 13,198 (65%) were known to be cured or still in care and 1,537 (8%) were LTFU and eligible for retrieval. Contact was established with 888/1,537 (58%) invited individuals; 369 (24%) had received prior successful treatment elsewhere, 131 (9%) refused re-evaluation and 251 (16%) were referred for re-evaluation. Finally, 219 (14%) were re-evaluated, of whom 172 (79%) approved additional data collection. HCV-RNA was positive in 143/172 (83%), of whom 38/143 (27%) had advanced fibrosis or cirrhosis and 123/143 (86%) commenced antiviral treatment. CONCLUSION: Our nationwide micro-elimination strategy accurately mapped the ever-diagnosed HCV population in the Netherlands and indicates that 27% of LTFU HCV-infected patients re-linked to care have advanced fibrosis or cirrhosis. This emphasizes the potential value of systematic retrieval for HCV elimination.

Background & Aims Shortened duration therapy for acute and recent HCV infection has been shown to be highly effective in several small non-randomised studies with direct-acting antiviral regimens; however, large randomised studies are lacking. Methods REACT was an NIH-funded multicentre international, open-label, randomised, phase IV non-inferiority trial examining the efficacy of short course (6-week) vs. standard course (12-week) therapy with sofosbuvir-velpatasvir for recent HCV infection (estimated duration of infection ≤12 months). Randomisation occurred at week 6. The primary endpoint was sustained virological response 12 weeks after treatment end (SVR12) in the intention-to treat (ITT) population. A total of 250 participants were due to be enrolled, but on advice of the data safety and monitoring board the study was halted early. Results The primary analysis population consisted of 188 randomised participants at termination of study enrolment; short arm (n = 93), standard arm (n = 95). Ninety-seven percent were male and 69% HIV positive. ITT SVR12 was 76/93, 81.7% (95% CI 72.4–89.0) in the short arm and 86/95, 90.5% (95% CI 82.7–95.6) in the standard arm. The difference between the arms was -8.8 (95% CI -18.6 to 1.0). In modified ITT analysis, wherein non-virological reasons for failure were excluded (death, reinfection, loss to follow-up), SVR12 was 76/85, 89.4% (95% CI 80.8–95.0) in the short arm and 86/88, 97.7% in the standard arm (95% CI 92.0–99.7; difference -8.3%, p = 0.025). Conclusions In this randomised study in recent HCV infection, a 6-week course of sofosbuvir-velpatasvir did not meet the criteria for non-inferiority to standard 12-week therapy. Lay summary In this randomised trial, 188 people with recently acquired hepatitis C infection were randomly assigned to treatment using either a short 6-week course (93 people) or standard 12-week course (95 people) of the hepatitis C treatment sofosbuvir/velpatasvir. There were 9 cases of relapse after treatment with the short course and 2 following the standard course. A shortened course of 6-week therapy for hepatitis C infection appeared to be less effective than a standard 12-week course in people with recently acquired hepatitis C infection.

INTRODUCTION: As the incidence of hepatitis C virus (HCV) infections remains high among human immunodeficiency virus (HIV)-positive men who have sex with men (MSM) an HCV testing strategy was introduced at the sexually transmitted infections (STI) clinic in Amsterdam in 2017. We aimed to evaluate this HCV testing strategy. METHODS: The HIV-positive MSM and transgender women (TGW) were eligible for HCV testing (anti-HCV and HCV ribonucleic acid) at the STI clinic if they did not visit their HIV clinician in the 3 months before the consultation and had not been tested for HCV at the STI clinic in the previous 6 months. All eligible individuals were administered the 6 questions on risk behavior of the HCV-MSM observational study of acute infection with hepatitis C (MOSAIC) risk score; a risk score of 2 or greater made a person eligible for testing. RESULTS: From February 2017 through June 2018, 1015 HIV-positive MSM and TGW were eligible for HCV testing in 1295 consultations. Eleven active HCV infections (HCV ribonucleic acid positive) were newly diagnosed (positivity rate, 0.9%; 95% confidence interval [CI], 0.4-1.5%). Sensitivity and specificity of the HCV-MOSAIC score for newly diagnosed active HCV infections were 80.0% (95% CI, 49.0-94.3%) and 53.7% (95% CI, 50.8-56.5%), respectively. If an HCV-MOSAIC score of 2 or greater were used to determine whom to test, 46.6% of individuals currently tested for HCV would be eligible for testing. CONCLUSIONS: Using the new HCV testing strategy, HCV testing was done in 1295 consultations with HIV-positive MSM and TGW in 17 months. We newly diagnosed 11 active HCV infections. The HCV-MOSAIC risk score could reduce the number of tests needed, but some active HCV infections will be missed.

- Abstract
BackgroundVaccines can be less immunogenic in people living with HIV (PLWH), but for SARS-CoV-2 vaccinations this is unknown.Methods and FindingsA prospective cohort study to examine the immunogenicity of BNT162b2, mRNA-1273, ChAdOx1-S and Ad26.COV2.S vaccines in adult PLWH, without prior COVID-19, compared to HIV-negative controls. The primary endpoint was the anti-spike SARS-CoV-2 IgG response after mRNA vaccination. Secondary endpoints included the serological response after vector vaccination, anti-SARS-CoV-2 T-cell response and reactogenicity.Between February-September 2021, 1154 PLWH (median age 53 [IQR 44-60], 86% male) and 440 controls (median age 43 [IQR 33-53], 29% male) were included. 884 PLWH received BNT162b2, 100 mRNA-1273, 150 ChAdOx1-S, and 20 Ad26.COV2.S. 99% were on antiretroviral therapy, 98% virally suppressed, and the median CD4+T-cell count was 710 cells/µL [IQR 520-913]. 247 controls received mRNA-1273, 94 BNT162b2, 26 ChAdOx1-S and 73 Ad26.COV2.S. After mRNA vaccination, geometric mean concentration was 1418 BAU/mL in PLWH (95%CI 1322-1523), and after adjustment for age, sex, and vaccine type, HIV-status remained associated with a decreased response (0.607, 95%CI 0.508-0.725). In PLWH vaccinated with mRNA-based vaccines, higher antibody responses were predicted by CD4+T-cell counts 250-500 cells/µL (2.845, 95%CI 1.876-4.314) or >500 cells/µL (2.936, 95%CI 1.961-4.394), whilst a viral load >50 copies/mL was associated with a reduced response (0.454, 95%CI 0.286-0.720). Increased IFN-γ, CD4+, and CD8+T-cell responses were observed after stimulation with SARS-CoV-2 spike peptides in ELISpot and activation induced marker assays, comparable to controls. Reactogenicity was generally mild without vaccine-related SAE.ConclusionAfter vaccination with BNT162b2 or mRNA-1273, anti-spike SARS-CoV-2 antibody levels were reduced in PLWH. To reach and maintain the same serological responses and vaccine efficacy as HIV-negative controls, additional vaccinations are probably required.

Background We determined the frequency of and factors associated with ≥10% weight gain and its metabolic effects in virally suppressed people with human immunodeficiency virus (PWH) from the Dutch national AIDS Therapy Evaluation in the Netherlands (ATHENA) cohort switching to tenofovir alafenamide (TAF) and/or integrase strand transfer inhibitor (INSTI). Methods We identified antiretroviral therapy–experienced but TAF/INSTI-naive PWH who switched to a TAF and/or INSTI-containing regimen while virally suppressed for >12 months. Individuals with comorbidities/comedication associated with weight change were excluded. Analyses were stratified by switch to only TAF, only INSTI, or TAF + INSTI. Factors associated with ≥10% weight gain were assessed using parametric survival models. Changes in glucose, lipids, and blood pressure postswitch were modeled using mixed-effects linear regression and compared between those with and without ≥10% weight gain. Results Among 1544 PWH who switched to only TAF, 2629 to only INSTI, and 918 to combined TAF + INSTI, ≥10% weight gain was observed in 8.8%, 10.6%, and 14.4%, respectively. Across these groups, weight gain was more frequent in Western and sub-Saharan African females than Western males. Weight gain was also more frequent in those with weight loss ≥1 kg/year before switching, age Conclusions Weight gain of ≥10% after switch to TAF and/or INSTI was common in virally suppressed PWH, particularly in females and those starting both drugs simultaneously. Consequent changes in metabolic parameters were, however, modest.

Medication non-adherence can be intentional or unintentional. We investigated the prevalence of unintentional and intentional non-adherence to antiretroviral therapy (ART) and the relationship with beliefs about medicines, sociodemographic- and HIV-related variables among people with HIV (PWH) attending the HIV clinic of the Amsterdam University Medical Centers. Participants completed the Medication Adherence Rating Scale (MARS) and the Beliefs about Medicines (BMQ) questionnaire. About half of 80 participants reported unintentional non-adherence and 20% reported intentional non-adherence. Both unintentional and intentional non-adherence were associated with younger age. Additionally, intentional non-adherence was associated with being a migrant from Suriname /Netherlands Antilles, having more concerns about negative effects of ART and stronger beliefs that medicines in general are overused/ overprescribed. In conclusion, intentional but not unintentional non-adherence was associated with beliefs about medicines. Eliciting and discussing beliefs about medicines may be a promising avenue to address patients’ concerns and perceptions thereby potentially enhancing medication adherence.
