Incidence and Predictors of Tuberculosis-associated IRIS in People With HIV Treated for Tuberculosis: Findings From Reflate TB2 Randomized Trial.

Background: After antiretroviral therapy (ART) initiation, people with HIV (PWH) treated for tuberculosis (TB) may develop TB-associated immune reconstitution inflammatory syndrome (TB-IRIS). Integrase inhibitors, by providing a faster HIV-RNA decline than efavirenz, might increase the risk for this complication. We sought to assess incidence and determinants of TB-IRIS in PWH with TB on raltegravir- or efavirenz-based ART. Methods: We conducted a secondary analysis of the Reflate TB 2 trial, which randomized ART-naive PWH on standard TB treatment, to receive raltegravir- or efavirenz-based ART. The primary objective was to evaluate the incidence of TB-IRIS. Incidence rate ratio comparing TB-IRIS incidence in each arm was calculated. Kaplan-Meier curves were used to compare TB-IRIS-free survival probabilities by ART arm. Cox regression models were fitted to analyze baseline characteristics associated with TB-IRIS. Results: Of 460 trial participants, 453 from Brazil, Côte d'Ivoire, Mozambique, and Vietnam were included in this analysis. Baseline characteristics were median age 35 years (interquartile range [IQR], 29-43), 40% female, 69% pulmonary TB only, median CD4, 102 (IQR, 38-239) cells/mm³, and median HIV RNA, 5.5 (IQR, 5.0-5.8) log copies/mL. Forty-eight participants developed TB-IRIS (incidence rate, 24.7/100 PY), 19 cases in the raltegravir arm and 29 in the efavirenz arm (incidence rate ratio 0.62, 95% confidence interval .35-1.10). Factors associated with TB-IRIS were: CD4 ≤ 100 cells/µL, HIV RNA ≥500 000 copies/mL, and extrapulmonary/disseminated TB. Conclusions: We did not demonstrate that raltegravir-based ART increased the incidence of TB-IRIS compared with efavirenz-based ART. Low CD4 counts, high HIV RNA, and extrapulmonary/disseminated TB at ART initiation were associated with TB-IRIS.

Harm reduction and multidisciplinary consultations for gay, bisexual, and other men who have sex with men practising chemsex based in a French infectious disease unit: patients' characteristics and perceptions.

BACKGROUND: Chemsex, a type of sexualised drug use, is expanding among gay, bisexual, and other men who have sex with men (GBMSM), with physical and mental health risks. Health-seeking behaviours of GBMSM practising chemsex is not clear. METHODS: Harm reduction (HR) consultations for GBMSM engaging in chemsex and seeking comprehensive services including HR were offered in a Parisian infectious disease unit. From December 2021 to January 2022, HR consultation patients completed an online survey on their consumption, health, used services, and perspective on consultations. We generated descriptive statistics, and tested (χ 2 ) the relationship between reporting a specialised follow-up and perceived usefulness of intervention. RESULTS: Of 172 patients, a total of 96 GBMSM (55.2%) completed the survey. Most ever consumed substance was 3-methylmethcathinone (3MMC; 92/96; 95.8%). Before consultations, about half consumed at least once a week (50/96; 52%), most reported negative impacts of chemsex on their social (60/96, 62.5%), professional (56/96, 58.3%), intimate (53/96; 55.21%), or sexual life (52/96; 54.17%). Also, more than two-thirds (n =57; 69.38%) had received a follow-up in specialised services: one-third had been followed in addictology (28/96, 29.2%) and/or psychotherapy (32/96, 33.3%), and one-fourth (24/96, 25.0%) had used emergency services. After consultations, three-quarters perceived the intervention as useful (n =74; 77.08%); we found no significant relationship with receiving a specialised follow-up; and most were satisfied with professionals' listening (90/96; 93.8%), and reported reduced risks (80/96; 83.3%). DISCUSSION: Multidisciplinary HR, preventive, diagnostical, and therapeutic sexological and psychiatric interventions are greatly needed among GBMSM practising chemsex. HR interventions accessible in services already attended by GBMSM are a valuable option.

Sexual behaviour and STIs among MSM living with HIV in the PrEP era: the French ANRS PRIMO cohort study.

INTRODUCTION: In a context of declining condom use and high sexually transmitted infection (STI) incidence, the diffusion of "treatment as prevention" (Tasp) and more recently pre-exposure prophylaxis (PrEP) may have changed the sexual behaviour of newly diagnosed men who have sex with men (MSM) with HIV. METHODS: Six hundred and nine MSM were enrolled and followed annually between 2014 and 2021 in the ANRS PRIMO Cohort (ClinicalTrials.gov:NCT03148964) from the time of HIV seroconversion. We studied changes over calendar time in sexual behaviour before and after HIV diagnosis. Factors associated with inconsistent condom use (ICU) after HIV diagnosis, PrEP use by partner(s) and bacterial STI acquisition were studied in random-effects models. RESULTS: In the 6 months preceding HIV diagnosis, the number of sexual partners decreased from a median of 10 (IQR: 4-19) in 2014 to 6 (3-11) in 2021. After HIV diagnosis, ICU increased from 57.1% (16/28) of visits in 2014 up to 84.2% (229/272) in 2020-2021. Up to 25% (63/229) of MSM with HIV in recent years reported the use of PrEP by their partner(s) as the reason for ICU; these MSM were less frequently in a stable relationship, had a higher number of sexual partners and higher education level than those who did not report the use of PrEP by their partner(s). STI incidence after HIV diagnosis increased between 2014 and 2016 and remained high afterwards. STI risk was no longer associated with PrEP use by partners after adjustment for the number of partners and calendar period. ICU, age below 35 years, not being in a stable relationship, higher number of sexual partners were independently associated with an increased risk of STI. CONCLUSIONS: Implementation of TasP and more recently PrEP has led to major changes in the sexual behaviour of MSM with HIV. ICU has become overwhelmingly prevalent, PrEP use by the partner increasingly being the reported reason for ICU, behind TasP, which remains the main reason. Characteristics of MSM at the time of diagnosis of HIV have changed, with fewer number of sexual partners today than in 2014, which must lead to broaden the indications for PrEP prescription. STIs incidence remains high in MSM with HIV and requires improvements in screening and prevention methods such as pre- or post-exposition antibiotics or vaccines.

Filling in the Gaps: Updates on Doxycycline Prophylaxis for Bacterial Sexually Transmitted Infections.

Over the past two decades, cases of sexually transmitted infections (STIs) due to syphilis, gonorrhea, and chlamydia have been rising in the United States, disproportionately among gay, bisexual, and other men who have sex with men (MSM), as well as racial and ethnic minorities of all genders. In this review, we address updates about the evidence on doxycycline post-exposure prophylaxis (doxy-PEP) for prevention of bacterial STIs, including efficacy, safety, antimicrobial resistance (AMR), acceptability, modeling population impact, and evolving guidelines for use. Equitable implementation of doxy-PEP will require evaluation of who is offered and initiates it, understanding patterns of use and longer-term STI incidence and AMR, provider training, and tailored community education.

Failure of bamlanivimab with selection of E484K mutation in an allogeneic stem cell transplant recipient with nosocomial SARS-CoV-2 infection.

We report the case of an allogeneic stem cell transplant recipient with nosocomial acquisition of SARS-CoV-2 infection who received antispike neutralizing monoclonal antibody bamlanivimab 2 days after diagnosis of SARS-CoV-2 infection but progressed to severe COVID-19 pneumonia and died with the selection of E484K/Q resistance mutations to bamlanivimab.

Switch to bictegravir/emtricitabine/tenofovir alafenamide from dolutegravir-based therapy: 96-week pooled analysis.

OBJECTIVE: To evaluate the efficacy and safety of 96 weeks of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) treatment in participants switching from dolutegravir (DTG)-based therapy. DESIGN: Studies 1489 (NCT02607930) and 1490 (NCT02607956) were phase 3 randomized, double-blind, active-controlled, first-line therapy trials in people with HIV-1. After 144 weeks of DTG-based or B/F/TAF treatment, participants could enter a 96-week open-label extension (OLE) of B/F/TAF. METHODS: A pooled analysis evaluated viral suppression (HIV-1 RNA <50 copies/mL) and changes in CD4+ cell count at OLE Weeks 48 and 96, treatment-emergent resistance, safety and tolerability after switch from a DTG-based regimen to B/F/TAF. Outcomes by prior treatment were summarized using descriptive statistics and compared by two-sided Wilcoxon rank sum test. RESULTS: At OLE Week 96, participants who switched to B/F/TAF (N=519) maintained high levels of virologic suppression (99.5% and 99.1% in those switching from DTG/abacavir/lamivudine and DTG+F/TAF, respectively) and CD4+ cell count, with no treatment-emergent resistance to B/F/TAF. Twenty-one participants experienced drug-related adverse events (AEs) after switching, with diarrhea, weight gain and headache occurring most commonly. There were no cases of proximal renal tubulopathy, drug-related Grade 4 AEs or serious AEs. Two participants discontinued B/F/TAF due to treatment-related AEs. Participants who switched from DTG/abacavir/lamivudine experienced statistically significant greater weight gain than those who switched from DTG+F/TAF; however, median weight change from the blinded phase baseline to OLE Week 96 was numerically similar across treatment groups. CONCLUSIONS: This medium-term analysis demonstrates the safety and efficacy of switching to B/F/TAF from a DTG-containing regimen in people with HIV-1.

Ex-vivo rectal tissue infection with HIV-1 to assess time to protection following oral preexposure prophylaxis with tenofovir disoproxil/emtricitabine.

OBJECTIVES: We wished to assess time to protection from HIV-1 infection following oral tenofovir disoproxil and emtricitabine (TDF/FTC) as preexposure prophylaxis (PrEP), using ex-vivo rectal tissue infections and drug concentration measures in blood and rectal tissue. DESIGN/METHODS: Participants from the ANRS PREVENIR study (NCT03113123) were offered this sub-study after a 14-day wash-out. We used an ex-vivo model to evaluate rectal tissue HIV-1 susceptibility before and after PrEP, 2 h after two pills or 7 days of a daily pill of TDF/FTC. PrEP efficacy was expressed by the difference (after-before) of 14-day cumulative p24 antigen levels. TFV-DP and FTC-TP levels were measured in rectal tissue and PBMCs and correlated with HIV-1 infection. RESULTS: Twelve and 11 men were analyzed in the 2 h-double dose and 7 days-single dose groups, respectively. Cumulative p24 differences after-before PrEP were -144 pg/ml/mg (IQR[-259;-108]) for the 2 h-double dose group ( P  = 0.0005) and -179 pg/ml/mg (IQR [-253;-86]) for the 7 days-single dose group ( P  = 0.001), with no differences between groups ( P  = 0.93). Rectal TFV-DP was below quantification after a double dose, but FTC-TP levels were similar to levels at 7 days. There was a significant correlation between rectal FTC-TP levels and p24 changes after a double dose ( R  = -0.84; P  = 0.0001). CONCLUSION: Oral TDF/FTC provided similar protection against HIV-1 infection of rectal tissue 2 h after a double dose or 7 days of a daily dose. At 2 h, this protection seems driven by high FTC-TP concentrations in rectal tissue. This confirms the importance of combining TDF and FTC to achieve early protection.

Brief Report: Incidence and Management of Complex Kidney Situations Among On-Demand and Daily HIV Pre-Exposure Prophylaxis Users.

BACKGROUND: We evaluated complex pre-exposure prophylaxis (PrEP) situations linked to kidney issues in a cohort of on-demand and daily PrEP users. SETTING: We conducted a single-center retrospective cohort study in France including all PrEP users who received a tenofovir disoproxil (TD)-emtricitabine (FTC) prescription between January 1, 2012 and December 31, 2019 with at least 1 creatinine measurement available before and after PrEP initiation. METHODS: A complex kidney situation (CKS) was defined as an estimated glomerular filtration rate (eGFR) <60 mL/minute/1.73m 2 on 2 consecutive measurements. We estimated the incidence of this event, described case management, and identified associated factors using a Cox model. RESULTS: Three thousand one hundred and fourteen individuals were included in this study. Almost all were men (99%) with a median age of 35 years, 25% had an eGFR <90 mL/minute/1.73m 2 at baseline, and 65% used on-demand PrEP. Nine users (0.29%) had a CKS at baseline; 8/9 initiated on-demand PrEP without renal function worsening after a median (interquartile range [IQR]) follow-up time of 14 months (7-31). Thirteen cases of CKS occurred during the follow-up for a 0.25 per 100 person-years incidence (95% confidence interval [CI]: [0.14; 0.45]). On-demand PrEP was used in 7/13 participants with no further episode of confirmed eGFR <60 mL/minute/1.73m 2 after a 17-month median follow-up (IQR 4-18). CKS was associated with an age ≥50 years (hazard ratio [HR] 13, 95% CI: [4-39]) or with a baseline eGFR <90 mL/minute/1.73m 2 (HR 34, 95% CI: [4-261]). 9/22 CKS were linked to high-protein intake for weight training. CONCLUSIONS: CKS were rare in our cohort. On-demand PrEP did not result in subsequent renal function worsening in these few situations.

HIV pre-exposure prophylaxis services, provision, and delivery in the European treatment network of HIV, hepatitis and global emerging infectious diseases (NEAT ID).

OBJECTIVES: We conducted a survey to evaluate HIV pre-exposure prophylaxis (PrEP) practices in a European clinical research network on HIV, hepatitis, and global infectious diseases (NEAT ID). METHODS: An online survey comprising 22 questions was sent via a secure electronic tool to the investigating physician of each of the 342 NEAT ID study centres across 15 European countries in November 2020. RESULTS: In total, 50 sites from 12 countries responded (15% response rate). Most sites were in Western Europe, two were in Poland, and one was in Hungary. Of the responding sites, 45 provided PrEP services for a total of 27 416 PrEP users, with 1361 new PrEP initiators each month. These centres supplied PrEP for men who have sex with men (100%), people who inject drugs (84%), sex workers (84%), women (62%), and transgender women (31%). PrEP persistence after 1 year was >90%, 75%-90%, and 40%-75% in 17, 24, and 4 centres, respectively. In total, 32/45 (71%) centres reported strong community-based organization commitment at their site, and 15/45 (33%) centres developed task-shifting processes to deliver PrEP through nurses (11/15), pharmacists (5/15), and key-population peers (2/15). The biggest barriers to implementation of PrEP were low awareness of and knowledge about PrEP (47%), unwillingness to disclose sexual identity or at-risk behaviour (36%), and lack of administrative support (29%). Of the 45 centres, 32 (71%) have already been involved in PrEP research and 43 (96%) were interested in participating in such studies. CONCLUSIONS: The few NEAT ID centres that responded to the survey showed disparities in PrEP deployment and practices despite a common interest in participating in research in this field.

Safety and efficacy of doravirine as first-line therapy in adults with HIV-1: week 192 results from the open-label extensions of the DRIVE-FORWARD and DRIVE-AHEAD phase 3 trials.

BACKGROUND: In two phase 3 trials for first-line therapy in adults with HIV-1, doravirine showed non-inferior efficacy, a favourable safety profile, and a superior lipid profile to darunavir and efavirenz through to 48 and 96 weeks. Here we report 192-week results from both studies. METHODS: DRIVE-FORWARD and DRIVE-AHEAD are multicentre, double-blind, randomised, active comparator-controlled, phase 3 trials of first-line antiretroviral treatment in adults with HIV-1. Eligible participants (aged ≥18 years) were naive to antiretroviral therapy, had plasma HIV-1 RNA 1000 copies per mL or more at screening, had no known resistance to any of the trial drugs, and had creatinine clearance 50 mL per min or more. DRIVE-FORWARD was conducted at 125 sites in 15 countries and compared doravirine (100 mg) with ritonavir-boosted darunavir (ritonavir [100 mg] and darunavir [800 mg]), each administered orally once daily with two nucleoside or nucleotide reverse transcriptase inhibitors (tenofovir disoproxil fumarate [300 mg] and emtricitabine [200 mg] or abacavir sulfate [600 mg] and lamivudine [300 mg]). DRIVE-AHEAD was conducted at 126 sites in 23 countries and compared doravirine (100 mg), lamivudine (300 mg), and tenofovir disoproxil fumarate (300 mg) with that of efavirenz (600 mg), emtricitabine (200 mg), and tenofovir disoproxil fumarate (300 mg), all administered orally once daily. DRIVE-FORWARD enrolment was between Dec 1, 2014, and June 1, 2020, and DRIVE-AHEAD enrolment was between June 10, 2015, and Aug 10, 2020. After the 96-week double-blind phase, eligible participants could enter an open-label extension and either continue doravirine or switch from comparator to doravirine for an additional 96 weeks. Efficacy (HIV-1 RNA <50 copies per mL) and safety assessments (adverse events and changes in laboratory parameters) were pooled. The DRIVE-FORWARD and DRIVE-AHEAD trials were registered with ClinicalTrials.gov, NCT02275780 and NCT02403674. FINDINGS: Of 1494 participants treated in the double-blind phase (1261 [84%] male and 233 [16%] female), 550 continued doravirine and 502 switched to doravirine in the extension. Using the FDA snapshot approach, HIV-1 RNA less than 50 copies per mL was maintained in 457 (83%) of 550 participants who continued doravirine and 404 (80%) of 502 participants who switched to doravirine. Protocol-defined virological failure and development of resistance were low, occurring mainly before week 96. Two (<1%) of 550 participants who continued doravirine reported serious drug-related adverse events, and three (1%) who continued doravirine and one (<1%) of 502 who switched to doravirine discontinued due to drug-related adverse events. Participants continuing or switching to doravirine showed generally favourable lipid profiles, little weight gain, and small decreases in estimated glomerular filtration rates, with no discontinuations due to increased creatinine or renal adverse events. INTERPRETATION: Favourable efficacy and safety profiles for doravirine at week 96 were maintained through to week 192 in participants who continued or switched to doravirine, supporting use of doravirine for long-term first-line HIV-1 treatment and for virologically suppressed adults switching therapy.

Prevention strategies for sexually transmitted infections, HIV, and viral hepatitis in Europe.

The current prevention efforts for STIs, HIV and viral hepatitis in the WHO European Region, especially in the Central and Eastern subregions, are hindered by healthcare disparities, data gaps, and limited resources. In this comprehensive narrative review, we aim to highlight both achievements and persisting challenges while also exploring new developments that could significantly impact the prevention of these infections in the near future. While pre-exposure prophylaxis (PrEP) for HIV has been broadly approved and implemented in 38 out of 53 countries in the region, challenges remain, including cost, limited licensing, and incomplete adherence. We explore innovative approaches like on-demand PrEP, long-acting injectable cabotegravir, and intravaginal rings that have shown promising results, alongside the use of six-monthly lenacapavir, the outcomes of which are pending. Additionally, the potential of doxycycline post-exposure prophylaxis has been discussed, revealing efficacy in reducing chlamydia and syphilis risk, but effectiveness against gonorrhoea being contingent on tetracycline resistance rates, and the need of further data to determine potential resistance development in other bacteria and its impact on the gut microbiome. We examine successful vaccination campaigns against HBV and HPV, the ongoing development of vaccines for chlamydia, syphilis, herpesvirus, and gonorrhoea, and challenges in HIV vaccine research, including lines of research with significant potential like sequential immunization, T-cell responses, and mRNA technology. This review underscores the research endeavors that pave the way for a more resilient and robust approach to combating STIs, HIV, and viral hepatitis in the region.

Major revision version 12.0 of the European AIDS Clinical Society guidelines 2023.

BACKGROUND: The European AIDS Clinical Society (EACS) guidelines were revised in 2023 for the 19th time, and all aspects of HIV care were updated. KEY POINTS OF THE GUIDELINES UPDATE: Version 12.0 of the guidelines recommend the same six first-line treatment options for antiretroviral treatment (ART)-naïve adults as versions 11.0 and 11.1: tenofovir-based backbone plus an unboosted integrase inhibitor or doravirine; abacavir/lamivudine plus dolutegravir; or dual therapy with lamivudine or emtricitabine plus dolutegravir. The long-acting section has been expanded in the ART and drug-drug interaction (DDI) panels. Tables for preferred and alternative ART in children and adolescents have been updated, as has the section on prevention of vertical transmission, particularly with new guidance for breastfeeding. A new DDI table has been included for the ART and anti-infective drugs used for opportunistic infections, sexually transmitted infections, and other infectious conditions; lenacapavir has been included in all DDI tables. New sections on alcohol use and patient-reported outcome measures (PROMs) have been included in the comorbidity panel, in addition to updates on many relevant topics, such as new resource guidance for deprescribing in people with HIV. Other sections, including travel, cognitive impairment, cancer screening, sexual health, and diabetes have also been revised extensively. The algorithm for the management of acute hepatitis C virus infection has been removed, as current guidelines recommend immediate treatment of all people with recently acquired hepatitis C virus. Updates on vaccination for hepatitis B virus and recommendations for simplification to tenofovir-free two-drug regimens in people with isolated anti-hepatitis B core antibodies are provided. In the opportunistic infections and COVID-19 panel, guidance on the management of COVID-19 in people with HIV has been updated according to the most up-to-date evidence, and a new section on monkeypox has been added. CONCLUSIONS: In 2023, the EACS guidelines were updated extensively and now include several new sections. The recommendations are available as a free app, in interactive web format, and as a pdf online.

Cryptococcal meningitis and cerebral vasculitis in a patient with primary intestinal lymphangiectasia: a case report.

Primary intestinal lymphangiectasia (Waldmann's disease) is a rare exudative enteropathy without precisely assessed infectious risk. We report the case of a 49-year-old male patient with meningitis and cerebral vasculitis due to Cryptococcus neoformans complicating Waldmann's disease diagnosed 12 years ago. The treatment combined liposomal amphotericin B, 3 mg/kg daily plus flucytosine 25 mg/kg/6 h, both intravenously during 15 days, then fluconazole 800 mg daily during 8 weeks, and finally 200 mg daily indefinitely. Dexamethasone 0.4 mg/kg daily during the first week was gradually decreased over 2 months. The outcome was good, and the patient is still followed 3 years later without any recurrence.

Two cases of extensively drug-resistant (XDR) Neisseria gonorrhoeae infection combining ceftriaxone-resistance and high-level azithromycin resistance, France, November 2022 and May 2023.

We report two extensively drug-resistant (XDR) Neisseria gonorrhoeae (NG) isolates combining high-level resistance to azithromycin and resistance to ceftriaxone, obtained in France from two heterosexual patients, one of whom returned from Cambodia. Whole genome sequencing identified MLST ST16406, the mosaic penA-60.001 which caused ceftriaxone resistance in the internationally spreading FC428 clone, and the A2059G mutation in the 23S rRNA gene. The NG isolates F93 and F94 were related to XDR isolates detected in Austria and the United Kingdom in 2022.

Prevalence, Risk factors, and Shedding of Human Herpes Virus-8 among Men Having Sex With Men Enrolled in a Pre-exposure Prophylaxis Study.

BACKGROUND: Seroprevalence and risk factors for Human Herpesvirus-8 (HHV-8) infection among HIV-negative men who have sex with men (MSM) on pre-exposure prophylaxis (PrEP) have not been well characterized. Our objectives were to assess the prevalence and incidence of HHV-8 infection in MSM enrolled on PrEP and assess viral shedding in seropositive participants. METHODS: The ANRS IPERGAY study enrolled 429 participants in France and Canada to evaluate oral PrEP for HIV-1 prevention. Stored sera samples at day 0 (D0) and last visit were tested for the detection of HHV-8 antibodies using an indirect immunofluorescence assay. Baseline characteristics were analyzed to identify risk factors associated with HHV-8 seropositivity. Among seropositive participants, HHV-8 DNA was quantified on available oral and anal swabs, and ORF-K1 typing performed on HHV-8 positive samples. RESULTS: One hundred participants were seropositive at D0 (prevalence of 24%, 95% Confidence Interval (95%CI): 20·0-28·4) and 18/329 seroconverted during the study (incidence rate of 2·66 per 100 person-years, 95%CI: 1·57-4·20). Risk factors independently associated with baseline HHV-8 seropositivity included older age, high number of sexual partners, chemsex use and HSV-2 seropositivity. Among HHV-8 seropositive participants with available swab(s) for virological analysis, 37/115 (32%) displayed HHV-8 oral shedding, and 5/113 (4.4%) anal shedding at least once. Four patients had positive viral load before seroconversion. CONCLUSION: Prevalence and incidence of HHV-8 infection were high in HIV-negative PrEP users. Among seropositive participants, HHV-8 DNA is mainly detected in saliva, which may play a major role in viral transmission in this population.

Efficacy and safety of the novel capsid inhibitor lenacapavir to treat multidrug-resistant HIV: week 52 results of a phase 2/3 trial.

BACKGROUND: Lenacapavir, a first-in-class HIV-1 capsid inhibitor, is in development as a long-acting agent for treating and preventing HIV-1. We aimed to evaluate the efficacy and safety of lenacapavir with an optimised background regimen in adults living with multidrug-resistant HIV-1 up to 52 weeks. METHODS: This ongoing, international, phase 2/3 trial at 42 sites included adults living with multidrug-resistant HIV-1. In cohort 1, 36 participants were randomly assigned (2:1) to add oral lenacapavir (600 mg, days 1 and 2; 300 mg, day 8) or placebo to an existing failing regimen. At day 15, those on oral lenacapavir received subcutaneous lenacapavir 927 mg every 26 weeks; those on placebo started lenacapavir (2-week oral lead-in then subcutaneous). Cohort 1 started an optimised background regimen on day 15. In cohort 2 (non-randomised), 36 participants started an optimised background regimen concurrent with lenacapavir (oral to subcutaneous). Here we report the secondary endpoints of plasma HIV-1 RNA of less than 50 copies per mL or less than 200 copies per mL at week 52 (US Food and Drug Administration snapshot algorithm) in cohort 1 along with results for cohorts 1 and 2 combined. This trial is registered with ClinicalTrials.gov, NCT04150068, and clinicaltrialregister.eu, EudraCT 2019-003814-16 and is ongoing. FINDINGS: Of 72 participants, 46 (64%) had CD4 counts of less than 200 cells per µL and 38 (53%) had no more than one fully active antiretroviral drug at baseline. In cohort 1, 30 of 36 participants (83%, 95% CI 67-94) had less than 50 HIV-1 RNA copies per mL and 31 of 36 participants (86%, 71-95) had less than 200 HIV RNA copies per mL, at week 52. In all, nine participants (four in cohort 1, five in cohort 2) had emergent lenacapavir resistance; four resuppressed (HIV-1 RNA <50 copies per mL) while maintaining lenacapavir use. One participant discontinued study drug owing to injection site reaction. INTERPRETATION: In participants with multidrug-resistant HIV-1, subcutaneous lenacapavir in combination with an optimised background regimen resulted in a high rate of virological suppression up to 52 weeks.

Updated mortality and causes of death in 2020-2021 in people with HIV: a multicenter study in France.

OBJECTIVE: The aim of this study was to assess updated mortality and causes of death in people with HIV (PWH) in France. DESIGN AND METHODS: We analyzed all deaths in PWH followed up between January 1, 2020, and December 31, 2021, in 11 hospitals in the Paris region. We described the characteristics and causes of death among deceased PWH, and evaluated the incidence of mortality and associated risk factors using a multivariate logistic regression. RESULTS: Of the 12 942 patients followed in 2020--2021, 202 deaths occurred. Mean annual incidence of death [95% confidence interval (95% CI)] was 7.8 per 1000 PWH (6.3-9.5). Forty-seven patients (23%) died from non-AIDS nonviral hepatitis (NANH)-related malignancies, 38 (19%) from non-AIDS infections (including 21 cases of COVID-19), 20 (10%) from AIDS, 19 (9%) from cardiovascular diseases (CVD), 17 (8.4%) from other causes, six (3%) from liver diseases, and five (2.5%) from suicides/violent deaths. The cause of death was unknown in 50 (24.7%) patients. Risks factors for death were age [adjusted odds ratio (aOR) 1.93; 1.66-2.25 by additional decade), AIDS history (2.23; 1.61-3.09), low CD4 + cell count (1.95; 1.36-2.78 for 200-500 cells/µl and 5.76; 3.65-9.08 for ≤200 versus > 500 cells/µl), and viral load more than 50 copies/ml (2.03; 1.33-3.08), both at last visit. CONCLUSION: NANH malignancies remained in 2020-2021 the first cause of death. COVID-19 accounted for more than half of the mortality related to non-AIDS infections over the period. Aging, AIDS history, and a poorer viro-immunological control were associated with death.
