Immune reconstitution and evolution of B cell stimulating cytokines after R-CHOP therapy for HIV-associated DLBCL.

HIV infection is associated with an increased risk of diffuse large B cell lymphoma (DLBCL) that persists despite the advent of combined anti-retroviral therapy. In this prospective study, we analyzed the evolution of B cell activating cytokines (IL-6, IL-10 and BAFF) and the co-evolution of main functional subsets of circulating B and T cells in 51 patients with HIV-associated DLBCL treated with R-CHOP. R-CHOP therapy was associated with a decrease of IL-10, whilst IL-6 levels fluctuated and BAFF levels increased during the first 3 months and decreased thereafter. We observed a rapid rise in CD19+ B cells composed mostly of naïve B cells whereas marginal zone-like B cells and memory B cells recovered gradually. With a median follow-up of 41 months, PFS and OS at 5 years were 61.8% (95CI 47.6-80.4%) and 67.4% (95CI 53.4-85.0%), respectively. Progression (17.5%) and sepsis (12.5%) were the main causes of death. Baseline risk factors for death and progression were poor R-IPI (p=0.049), NK cell lymphopenia (p=0.001), lower proportion of naïve B cells among B cell compartment (p=0.017) and higher IL-6 serum levels (p=0.001). Our data suggest that patients treated with R-CHOP for HIV-associated DLBCL have a disturbed peripheral B cell compartment and that the low pool size of circulating naïve B cells affects negatively clinical outcome in these patients. In an era of rapid development of B cell-depleting therapies including B cell-targeting CAR-T cells, baseline and post-treatment assessment of perturbations within non-tumoral B cells counterpart are warranted for proper risk profiling in HIV-associated DLBCL.

Changes in bodyweight after initiating antiretroviral therapy close to HIV-1 seroconversion: an international cohort collaboration.

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

Safety and tolerability of immune checkpoint inhibitors in people with HIV infection and cancer: insights from the national prospective real-world OncoVIHAC ANRS CO24 cohort study.

BACKGROUND: Immune checkpoint inhibitors (ICIs) have been a major advance in cancer management. However, we still lack prospective real-world data regarding their usage in people with HIV infection (PWH). METHODS: The ANRS CO24 OncoVIHAC study (NCT03354936) is an ongoing prospective observational cohort study in France of PWH with cancer treated with ICI. We assessed the incidence of grade ≥3 immune-related adverse events (irAEs). All grade ≥3 irAEs were reviewed by an event review. RESULTS: Between January 17, 2018, and December 05, 2023, 150 participants were recruited from 33 sites and 140 were included in this analysis. At the data cut-off date of December 05, 2023, the median follow-up was 9.2 months (IQR: 3.9-18.3), with a total of 126.2 person-years.Median age was 59 years (IQR: 54-64) and 111 (79.3%) were men. Median time since HIV diagnosis was 25 years (12-31), the median duration on antiretroviral (ARV) was 19.5 years (7.7-25.4), and the CD4 nadir was 117/µL (51-240). ICI regimens comprised anti-programmed cell death protein-1 (PD-1) for 111 (79.3%) participants, anti-programmed death-ligand 1 for 25 (17.9%), a combination of anti-PD-1 and anti-cytotoxic T-lymphocyte associated protein 4 for 3 (2.1%), and anti-PD-1 along with anti-vascular endothelial growth factor receptor for 1 (0.7%). The most frequent cancers were lung (n=65), head/neck (n=15), melanoma (n=12), liver (n=11) and Hodgkin's lymphoma (n=9).During follow-up, a total of 34 grade ≥3 irAEs occurred in 20 participants, leading to an incidence rate of 26.9 per 100 person-years. The Kaplan-Meier estimates of the proportion of participants with at least one episode of grade ≥3 irAEs were 13.8% at 6 months, 15.0% at 12 months and 18.7% at 18 months. One treatment-related death due to myocarditis was reported (0.7%). Multivariable analysis of cumulative incidence showed that participants with time since HIV diagnosis >17 years (incidence rate ratio (IRR)=4.66, p=0.002), with CD4<200 cells/µL (IRR=4.39, p<0.0001), with positive cytomegalovirus (CMV) serology (IRR=2.76, p=0.034), with history of cancer surgery (IRR=3.44, p=0.001) had a higher risk of incidence of grade ≥3 irAEs. CONCLUSION: This study showed that the incidence of a first episode of grade ≥3 irAE was 15.0% (95% CI: 9.6% to 22.9%) at 1 year and the cumulative incidence of all severe irAE episodes was 26.9 per 100 person-years. Low CD4 count, positive CMV serology, history of cancer surgery and a longer time since HIV diagnosis were associated with the occurrence of severe irAEs.

Impact of vaccination with third generation modified vaccinia Ankara and sexual behaviour on mpox incidence in men who have sex with men: analysis among participants of the ANRS-174 DOXYVAC trial.

Background: Mpox was first reported in France on May 19 and third-generation live Modified Vaccinia Ankara (MVA-BN) vaccination of multiple-partner men who have sex with men (MSM) was recommended as of July 11, 2022. We assessed the impact of vaccination and of sexual behavior adopted during the epidemic period on mpox incidence in the ANRS-174-DOXYVAC trial enrolling MSM on HIV pre-exposure prophylaxis (PrEP) with history of sexually-transmitted infections (STI) in the previous year. Methods: We compared pre-epidemic socio-behavioral characteristics and change in sexual behaviors after the onset of the epidemic of participants with mpox and mpox-free. Then we compared incidence rates of mpox per 1000 person-months (p-m) between May 9-July 10 (before vaccination of MSM, period-1) and July 11-September 20 2022 (after vaccination launch, period-2) and explored factors explaining the period effect using Poisson regression model. Findings: 472 MSM had data before and after May 9, 2022. Twenty percent had received smallpox vaccine during childhood. Mpox occurred in 77/472 participants (incidence 49.3 per 1000 p-m (95% CI 38.9-61.6)). MVA-BN vaccination roll-out was rapid, with 86% (341/398) of eligible participants having received at least one dose by September 20, 2022. Sexual behavior significantly changed before and after May 9, with a decrease in the proportion of mpox-free participants with >10 partners during last 3 months (45% vs 38%, p = 0.0035). Mpox incidence was 67.4 per 1000 p-m (95% CI 51.6-86.6) in period-1, and 24.4 per 1000 p-m (95% CI 13.9-39.6) in period-2, with an incidence rate ratio of 0.36 (95% CI 0.21-0.63). In multivariable Poisson regression model, only MVA-BN vaccination in 2022 remained significantly associated with mpox incidence, with a 99% risk reduction (95% CI 96.6-99.7). Interpretation: In MSM on PrEP enrolled in the ANRS-174-DOXYVAC trial, rapid roll-out of MVA-BN vaccination was associated with a strong reduction in mpox incidence.

Doxycycline prophylaxis and meningococcal group B vaccine to prevent bacterial sexually transmitted infections in France (ANRS 174 DOXYVAC): a multicentre, open-label, randomised trial with a 2 × 2 factorial design.

BACKGROUND: Increased rates of sexually transmitted infections (STIs) are reported among men who have sex with men (MSM) and new interventions are needed. We aimed to assess whether post-exposure prophylaxis (PEP) with doxycycline could reduce the incidence of chlamydia or syphilis (or both) and whether the meningococcal group B vaccine (4CMenB) could reduce the incidence of gonorrhoea in this population. METHODS: ANRS 174 DOXYVAC is a multicentre, open-label, randomised trial with a 2 × 2 factorial design conducted at ten hospital sites in Paris, France. Eligible participants were MSM aged 18 years or older, HIV negative, had a history of bacterial STIs within the 12 months before enrolment, and who were already included in the ANRS PREVENIR study (a cohort of MSM using pre-exposure prophylaxis with tenofovir and emtricitabine for HIV prevention). Participants were randomly assigned (2:1) to doxycycline PEP (two pills of 100 mg each orally within 72 h after condomless sex, with no more than three doses of 200 mg per week) or no PEP groups and were also randomly assigned (1:1) to the 4CMenB vaccine (GlaxoSmithKline, Paris, France; two intramuscular injections at enrolment and at 2 months) or no vaccine groups, using a computer-generated randomisation list with a permuted fixed block size of four. Follow-up occurred for at least 12 months (with visits every 3 months) up to 24 months. The coprimary outcomes were the risk of a first episode of chlamydia or syphilis (or both) after the enrolment visit at baseline for the doxycycline intervention and the risk of a first episode of gonorrhoea starting at month 3 (ie, 1 month after the second vaccine dose) for the vaccine intervention, analysed in the modified intention-to-treat population (defined as all randomly assigned participants who had at least one follow-up visit). This trial is registered with ClinicalTrials.gov, NCT04597424 (ongoing). FINDINGS: Between Jan 19, 2021, and Sept 19, 2022, 556 participants were randomly assigned. 545 (98%) participants were included in the modified intention-to-treat analysis for the doxycycline PEP and no PEP groups and 544 (98%) were included for the 4CMenB vaccine and no vaccine groups. The median follow-up was 14 months (IQR 9-18). The median age was 40 years (34-48) and all 545 participants were male. There was no interaction between the two interventions (p≥0·1) for the primary outcome. The incidence of a first episode of chlamydia or syphilis (or both) was 8·8 per 100 person-years (35 events in 362 participants) in the doxycycline PEP group and 53·2 per 100 person-years (80 events in 183 participants) in the no PEP group (adjusted hazard ratio [aHR] 0·17 [95% CI 0·12-0·26]; p<0·0001). The incidence of a first episode of gonorrhoea, starting from month 3 was 58·3 per 100 person-years (103 events in 274 participants) in the 4CmenB vaccine group and 77·1 per 100 person-years (122 events in 270 participants) in the no vaccine group (aHR 0·78 [95% CI 0·60-1·01]; p=0·061). There were no deaths during the study. One drug-related serious adverse event (fixed-drug eruption) occurred in the doxycycline PEP group. Six (2%) participants in the doxycycline group discontinued doxycycline PEP because of gastrointestinal adverse events. INTERPRETATION: Doxycycline PEP strongly reduced the incidence of chlamydia and syphilis in MSM, but we did not show efficacy of the 4CmenB vaccine for gonorrhoea. Doxycycline PEP should be assessed in other populations, such as heterosexual men and women, and its effect on antimicrobial resistance carefully monitored.

Cardiac Adverse Events and Remdesivir in Hospitalized Patients With COVID-19: A Post Hoc Safety Analysis of the Randomized DisCoVeRy Trial.

BACKGROUND: We aimed to evaluate the cardiac adverse events (AEs) in hospitalized patients with coronavirus disease 2019 (COVID-19) who received remdesivir plus standard of care (SoC) compared with SoC alone (control), as an association was noted in some cohort studies and disproportionality analyses of safety databases. METHODS: This post hoc safety analysis is based on data from the multicenter, randomized, open-label, controlled DisCoVeRy trial in hospitalized patients with COVID-19. Any first AE that occurred between randomization and day 29 in the modified intention-to-treat (mITT) population randomized to either remdesivir or control group was considered. Analysis was performed using Kaplan-Meier survival curves, and Kaplan-Meier estimates were calculated for event rates. RESULTS: Cardiac AEs were reported in 46 (11.2%) of 410 and 48 (11.3%) of 423 patients in the mITT population (n = 833) enrolled in the remdesivir and control groups, respectively. The difference between both groups was not significant (hazard ratio [HR], 1.0; 95% confidence interval [CI], .7-1.5; P = .98), even when serious and nonserious cardiac AEs were evaluated separately. The majority of reports in both groups were of arrhythmic nature (remdesivir, 84.8%; control, 83.3%) and were associated with a favorable outcome. There was no significant difference between the two groups in the occurrence of cardiac AE subclasses, including arrhythmic events (HR, 1.1; 95% CI, .7-1.7; P = .68). CONCLUSIONS: Remdesivir treatment was not associated with an increased risk of cardiac AEs compared with control in patients hospitalized with moderate or severe COVID-19. These results are consistent with other randomized, controlled trials and meta-analyses. Clinical Trials Registration. NCT04315948; EudraCT 2020-000936-23.

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.

Association between SARS-CoV-2 viral kinetics and clinical score evolution in hospitalized patients.

The role of antiviral treatment in coronavirus disease 2019 hospitalized patients is controversial. To address this question, we analyzed simultaneously nasopharyngeal viral load and the National Early Warning Score 2 (NEWS-2) using an effect compartment model to relate viral dynamics and the evolution of clinical severity. The model is applied to 664 hospitalized patients included in the DisCoVeRy trial (NCT04315948; EudraCT 2020-000936-23) randomly assigned to either standard of care (SoC) or SoC + remdesivir. Then we use the model to simulate the impact of antiviral treatments on the time to clinical improvement, defined by a NEWS-2 score lower than 3 (in patients with NEWS-2 <7 at hospitalization) or 5 (in patients with NEWS-2 ≥7 at hospitalization), distinguishing between patients with low or high viral load at hospitalization. The model can fit well the different observed patients trajectories, showing that clinical evolution is associated with viral dynamics, albeit with large interindividual variability. Remdesivir antiviral activity was 22% and 78% in patients with low or high viral loads, respectively, which is not sufficient to generate a meaningful effect on NEWS-2. However, simulations predicted that antiviral activity greater than 99% could reduce by 2 days the time to clinical improvement in patients with high viral load, irrespective of the NEWS-2 score at hospitalization, whereas no meaningful effect was predicted in patients with low viral loads. Our results demonstrate that time to clinical improvement is associated with time to viral clearance and that highly effective antiviral drugs could hasten clinical improvement in hospitalized patients with high viral loads.

Brentuximab vedotin with AVD for stage II-IV HIV-related Hodgkin lymphoma (AMC 085): phase 2 results from an open-label, single arm, multicentre phase 1/2 trial.

BACKGROUND: Brentuximab vedotin in combination with doxorubicin, vinblastine, and dacarbazine (AVD) is approved in the upfront setting for advanced stage classical Hodgkin lymphoma (cHL). People living with HIV have been excluded from these studies. We aimed to understand the activity and safety of brentuximab vedotin-AVD in people living with HIV diagnosed with Hodgkin lymphoma, while focusing on HIV disease parameters and antiretroviral therapy (ART) interactions. METHODS: We present the phase 2 portion of a multicentre phase 1/2 study. Eligible patients were 18 years or older, had untreated stage II-IV HIV-associated cHL (HIV-cHL), a Karnofsky performance status of more than 30%, a CD4+ T-cell count of 50 cells per µL or more, were required to take ART, and were not on strong CYP3A4 or P-glycoprotein inhibitors. Patients were treated intravenously with 1·2 mg/kg of brentuximab vedotin (recommended phase 2 dose) with standard doses of AVD for six cycles on days 1 and 15 of a 28-day cycle. The primary endpoint of the phase 2 portion was 2-year progression-free survival (PFS), assessed in all eligible participants who began treatment. Accrual has been completed. This trial is registered at ClinicalTrials.gov, NCT01771107. FINDINGS: Between March 8, 2013, and March 7, 2019, 41 patients received study therapy with a median follow up of 29 months (IQR 16-38). 34 (83%) of 41 patients presented with stage III-IV and seven (17%) with stage II unfavourable HIV-cHL. 37 (90%) of 41 patients completed therapy, all 37 of whom achieved complete response. The 2-year PFS was 87% (95% CI 71-94) and the overall survival was 92% (78-97). The most common grade 3 or worse adverse events were peripheral sensory neuropathy (four [10%] of 41 patients), neutropenia (18 [44%]), and febrile neutropenia (five [12%]). One treatment-related death was reported, due to infection. INTERPRETATION: Brentuximab vedotin-AVD was highly active and had a tolerable adverse event rate in HIV-cHL and is an important therapeutic option for people with HIV-cHL. The complete reponse rate is encouraging and is possibly related to a unique aspect of HIV-cHL biology. Upcoming 5-year data will evaluate the sustainability of the outcomes obtained.

Latent Tuberculosis Infection and Associated Risk Factors among People Living with HIV and HIV-Uninfected Individuals in Lithuania.

BACKGROUND: People living with HIV (PLHIV) with latent tuberculosis infection (LTBI) are at increased risk of tuberculosis (TB) reactivation compared to the HIV-negative population. Lithuania belongs to the 18 high-priority TB countries in the European region. The aim of this study was to compare the prevalence of LTBI and LTBI-related risk factors between PLHIV and HIV-uninfected populations. METHODS: A cross-sectional study was conducted in three Lithuanian Infectious Diseases centres from August 2018 to May 2022 using the interferon gamma release assay (IGRA) and tuberculin skin test (TST) in Vilnius, and IGRA only in Siauliai and Klaipeda. Cohen's kappa was used to assess IGRA and TST agreement. A structured questionnaire was completed by the study participants. LTBI-related risk factors were identified using a multivariable logistic regression model. RESULTS: In total, 391 PLHIV and 443 HIV-uninfected individuals enrolled, with a median age of 41 (IQR 36-48) and 43 (IQR 36-50), consisting of 69.8% and 65.5% male, respectively. The prevalence of LTBI defined by positive IGRA and/or TST among PLHIV was higher compared to that in the HIV-uninfected population (20.5% vs. 15.3%; OR 1.42; 95% CI 1.02-2.03; p = 0.04). The concordance between IGRA and TST was fair: kappa = 0.23 (95% CI 0.09-0.34). In multivariable analyses, association with injecting drug use (IDU) (ORa 2.25, 95% CI 1.27-3.99, p = 0.01) and imprisonment (ORa 1.99, 95% CI 1.13-3.52, p = 0.02) in all participants, IDU (ORa 2.37, 95% CI 1.09-5.15; p = 0.029) in PLHIV and a history of contact with an active TB patient (ORa 3.33, 95% CI 1.53-7.24; p = 0.002) in HIV-uninfected individuals were significant associations evidenced by LTBI. CONCLUSIONS: The prevalence of LTBI among PLHIV in Lithuania is higher compared to that in the HIV-uninfected population and the European average. The association with IDU in PLHIV emphasizes the need for integrated HIV, TB and substance abuse treatment to provide patient-centred care.

Management of pharmacovigilance during the COVID-19 pandemic crisis by the safety department of an academic sponsor: Lessons learnt and challenges from the EU DisCoVeRy clinical trial.

The current COVID-19 pandemic was an exceptional health situation, including for drug use. As there was no known effective drug for COVID-19 at the beginning of the pandemic, different drug candidates were proposed. In this article, we present the challenges for an academic Safety Department to manage the global safety of a European trial during the pandemic. The National Institute for Health and Medical Research (Inserm) conducted a European multicenter, open-label, randomized, controlled trial involving three repurposed and one-in development drugs (lopinavir/ritonavir, IFN-ß1a, hydroxychloroquine, and remdesivir) in adults hospitalized with COVID-19. From 25 March 2020 to 29 May 2020, the Inserm Safety Department had to manage 585 Serious Adverse Events (SAEs) initial notification and 396 follow-up reports. The Inserm Safety Department's staff was mobilized to manage these SAEs and to report Expedited safety reports to the competent authorities within the legal timeframes. More than 500 queries were sent to the investigators due to a lack of or incoherent information on SAE forms. At the same time, the investigators were overwhelmed by the management of patients suffering from COVID-19 infection. These particular conditions of missing data and lack of accurate description of adverse events made evaluation of the SAEs very difficult, particularly the assessment of the causal role of each investigational medicinal product. In parallel, working difficulties were accentuated by the national lockdown, frequent IT tool dysfunctions, delayed implementation of monitoring and the absence of automatic alerts for SAE form modification. Although COVID-19 is a confounding factor per se, the delay in and quality of SAE form completion and the real-time medical analysis by the Inserm Safety Department were major issues in the quick identification of potential safety signals. To conduct a high-quality clinical trial and ensure patient safety, all stakeholders must take their roles and responsibilities.

Impact of corticosteroids use on midterm sequelae in survivors of COVID-19 admitted to hospital: A prospective cohort study.

An understanding of the midterm sequelae in COVID-19 and their association with corticosteroids use are needed. Between March and July 2020, we evaluated 1227 survivors of COVID-19, 3 months posthospitalization, of whom 213 had received corticosteroids within 7 days of admission. Main outcome was any midterm sequelae (oxygen therapy, shortness of breath, one major clinical sign, two minor clinical signs or three minor symptoms). Association between corticosteroids use and midterm sequelae was assessed using inverse propensity-score weighting models. Our sample included 753 (61%) male patients, and 512 (42%) were older than 65 years. We found a higher rate of sequelae among users than nonusers of corticosteroids (42% vs. 35%, odds ratio [OR] 1.40 [1.16-1.69]). Midterm sequelae were more frequent in users of low-dose corticosteroids than nonusers (64% vs. 51%, OR 1.60 [1.10-2.32]), whereas no association between higher doses (≥20 mg/day equivalent of dexamethasone) and sequelae was evidenced (OR 0.95 [0.56-1.61]). Higher risk of sequelae with corticosteroids use was observed among subjects with propensity score below the 90th percentile. Our study suggest that corticosteroids use during hospitalization for COVID-19 is associated with higher risk of midterm sequelae.

Four days/week antiretroviral maintenance strategy (ANRS 170 QUATUOR): substudies of reservoirs and ultrasensitive drug resistance.

BACKGROUND: In a 4 days/week (4/7 days) maintenance strategy (ANRS-170 QUATUOR trial), the virological impact of an intermittent strategy was assessed by ultrasensitive virological analyses of reservoirs and resistance. METHODS: HIV-1 total DNA, ultra-sensitive plasma viral load (USpVL) and semen VL were measured in the first 121 participants. Sanger and ultra-deep sequencing (UDS) were performed on the HIV-1 genome (Illumina technology) according to the ANRS consensus. A generalized estimation equation with a Poisson distribution was used to compare changes in the proportion of residual viraemia, detectable semen HIV RNA and HIV DNA within and between the two groups over time. RESULTS: The proportion of participants with residual viraemia at Day 0 (D0) and Week 48 (W48) was 16.7% and 25.0% in the 4/7 days group and 22.4% and 29.7% in the 7/7 days group, respectively (+8.3% versus +7.3%, P = 0.971). The proportion of detectable DNA (>40 copies/106 cells) at D0 and W48 was 53.7% and 57.4% in the 4/7 days group and 56.1% and 51.8% in the 7/7 days group, respectively (+3.7% versus -4.3%, P = 0.358). Semen HIV RNA was detectable (≥100 copies/mL) in 2.2% of participants at D0 and 4.5% at W48 in the 4/7 days group versus 6.1% and 9.1% in the 7/7 days group, respectively (+2.3% versus +3.0%, P = 0.743). Emerging resistance at failure was more frequent in the 4/7 days group detected by Sanger sequencing: 3/6 participants versus 1/4 in the 7/7 days group, and similar with the UDS assay: 5/6 versus 4/4, respectively. CONCLUSIONS: These findings support the potency of a 4/7 days maintenance strategy on virological suppression at the reservoirs and emergent resistance level, including minority variants.

Mortality in hepatitis C virus-cured vs. hepatitis C virus-uninfected people with HIV.

OBJECTIVE: It is unknown whether hepatitis C virus (HCV)-cured people with HIV (PWH) without cirrhosis reached the same mortality risk as HCV-uninfected PWH. We aimed to compare mortality in PWH cured of HCV by direct-acting antivirals (DAAs) to mortality in individuals with HIV monoinfection. DESIGN: Nationwide hospital cohort. METHODS: HIV-controlled participants without cirrhosis and HCV-cured by DAAs started between September 2013 and September 2020, were matched on age (±5 years), sex, HIV transmission group, AIDS status, and body mass index (BMI) (±1 kg/m 2 ) to up to 10 participants with a virally suppressed HIV monoinfection followed at the time of HCV cure ±6 months. Poisson regression models with robust variance estimates were used to compare mortality in both groups after adjusting for confounders. RESULTS: The analysis included 3961 HCV-cured PWH (G1) and 33 872 HCV-uninfected PWH (G2). Median follow-up was 3.7 years in G1 [interquartile range (IQR): 2.0-4.6], and 3.3 years (IQR: 1.7-4.4) in G2. Median age was 52.0 years (IQR: 47.0-56.0), and 29 116 (77.0%) were men. There were 150 deaths in G1 [adjusted incidence rate (aIR): 12.2/1000 person-years] and 509 (aIR: 6.3/1000 person-years) in G2, with an incidence rate ratio (IRR): 1.9 [95% confidence interval (CI), 1.4-2.7]. The risk remained elevated 12 months post HCV cure (IRR: 2.4 [95% CI, 1.6-3.5]). Non-AIDS/non-liver-related malignancy was the most common cause of death in G1 (28 deaths). CONCLUSIONS: Despite HCV cure and HIV viral suppression, after controlling on factors related to mortality, DAA-cured PWH without cirrhosis remain at higher risk of all-cause mortality than people with HIV monoinfection. A better understanding of the determinants of mortality is needed in this population.

The socio-demographic, clinical characteristics and outcomes of tuberculosis among HIV infected adults in Lithuania: A thirteen-year analysis.

BACKGROUND: Tuberculosis (TB) is a public health problem in Lithuania, among the 18 high-priority TB countries in the European region, and the most common AIDS-indicative disease with the highest proportion in the EU/EEA since 2015. The study aimed to identify socio-demographic, clinical characteristics and their relationship with TB outcomes in TB-HIV co-infected patients in Lithuania. METHODS: A retrospective chart review analysed the characteristics of TB-HIV co-infected adults registered in State Information System of Tuberculosis over 2008-2020. The factors associated with drug-resistant TB and unsuccessful treatment outcome were identified by multivariable logistic regression. RESULTS: The study included 345 cases in 311 patients (239 new, 106 previously treated cases), median age 40 years (IQR 35-45), 80.7% male. 67.8% patients knew their HIV-positive status before TB diagnosis, median time to TB diagnosis was 8 years (IQR 4-12). 83.6% were unemployed, 50.5%-anytime intravenous drug users (IDU), 34.9% abused alcohol. Drug-resistant TB rates in new and previously treated TB cases were 38.1% and 61.3%, respectively. In multivariable analysis, higher risk of drug-resistant TB was associated with imprisonment in new (aOR 3.35; 95%CI 1.17-9.57) and previously treated (aOR 6.63; 95%CI 1.09-40.35) cases. In 52.3% of new TB cases and in 42.5% previously treated TB cases the treatment outcomes were unsuccessful. In multivariable analysis of new TB cases, current imprisonment (aOR 2.77; 95%CI 1.29-5.91) and drug-resistant TB (aOR 2.18; 95%CI 1.11-4.28) were associated with unsuccessful treatment outcome. In multivariable analysis of previously treated TB cases, female gender (aOR 11.93; 95%CI 1.86-76.69), alcohol abuse (aOR 3.17; 95%CI 1.05-9.58), drug-resistant TB (aOR 4.83; 95%CI 1.53-15.28) were associated with unsuccessful treatment outcome. CONCLUSIONS: In the TB-HIV-infected adult cohort in Lithuania, unemployment, imprisonment, IDU, alcohol abuse, known to be risk factors for TB, were very frequent. Drug resistance was an undeniable risk factor for unsuccessful treatment outcome and imprisonment was associated with drug resistant TB.

Effects of remdesivir in patients hospitalised with COVID-19: a systematic review and individual patient data meta-analysis of randomised controlled trials.

BACKGROUND: Interpretation of the evidence from randomised controlled trials (RCTs) of remdesivir in patients treated in hospital for COVID-19 is conflicting. We aimed to assess the benefits and harms of remdesivir compared with placebo or usual care in these patients, and whether treatment effects differed between prespecified patient subgroups. METHODS: For this systematic review and meta-analysis, we searched PubMed, Embase, the Cochrane COVID-19 trial registry, ClinicalTrials.gov, the International Clinical Trials Registry Platform, and preprint servers from Jan 1, 2020, until April 11, 2022, for RCTs of remdesivir in adult patients hospitalised with COVID-19, and contacted the authors of eligible trials to request individual patient data. The primary outcome was all-cause mortality at day 28 after randomisation. We used multivariable hierarchical regression-adjusting for respiratory support, age, and enrollment period-to investigate effect modifiers. This study was registered with PROSPERO, CRD42021257134. FINDINGS: Our search identified 857 records, yielding nine RCTs eligible for inclusion. Of these nine eligible RCTs, individual data were provided for eight, covering 10 480 patients hospitalised with COVID-19 (99% of such patients included in such RCTs worldwide) recruited between Feb 6, 2020, and April 1, 2021. Within 28 days of randomisation, 662 (12·5%) of 5317 patients assigned to remdesivir and 706 (14·1%) of 5005 patients assigned to no remdesivir died (adjusted odds ratio [aOR] 0·88, 95% CI 0·78-1·00, p=0·045). We found evidence for a credible subgroup effect according to respiratory support at baseline (pinteraction=0·019). Of patients who were ventilated-including those who received high-flow oxygen-253 (30·0%) of 844 patients assigned to remdesivir died compared with 241 (28·5%) of 846 patients assigned to no remdesivir (aOR 1·10 [0·88-1·38]; low-certainty evidence). Of patients who received no oxygen or low-flow oxygen, 409 (9·1%) of 4473 patients assigned to remdesivir died compared with 465 (11·2%) of 4159 patients assigned to no remdesivir (0·80 [0·70-0·93]; high-certainty evidence). No credible subgroup effect was found for time to start of remdesivir after symptom onset, age, presence of comorbidities, enrolment period, or corticosteroid use. Remdesivir did not increase the frequency of severe or serious adverse events. INTERPRETATION: This individual patient data meta-analysis showed that remdesivir reduced mortality in patients hospitalised with COVID-19 who required no or conventional oxygen support, but was underpowered to evaluate patients who were ventilated when receiving remdesivir. The effect size of remdesivir in patients with more respiratory support or acquired immunity and the cost-effectiveness of remdesivir remain to be further elucidated. FUNDING: EU-RESPONSE.

Striking differences in weight gain after cART initiation depending on early or advanced presentation: results from the ANRS CO4 FHDH cohort.

BACKGROUND: Many studies have reported weight gain in ART-naive people living with HIV (PWH) initiating an integrase strand-transfer inhibitor-based regimen. We studied the impact of early or advanced presentation and that of individual drugs in PWH initiating combined ART (cART) between 2012 and 2018. METHODS: From the French Hospital Database HIV cohort, we assessed factors associated with a weight gain  ≥10%, weight change after cART initiation or BMI increase  ≥5 kg/m2 up to 30 months. The analyses were conducted overall, and among PWH with early (primary infection or CD4 >350/mm3 and viral load  <100 000 copies/mL, without AIDS) and advanced presentation (AIDS or CD4 <200/mm3, not during primary infection). RESULTS: At 30 months, 34.5% (95% CI: 33.5-35.6) of the 12 773 PWH had a weight gain ≥10%, with 20.9% (95% CI: 19.6-22.2) among the 5794 with early presentation and 63.1% (95% CI: 60.9-65.3) among the 3106 with advanced presentation. Weight gain was 2.8 kg (95% CI: 2.0-3.7) for those with early presentation and 9.7 kg (95% CI: 8.4-11.1) for those with advanced presentation. Most weight gain occurred in the first 12 months. Underweight and obese PWH were at significantly higher risk of a BMI increase  ≥5 kg/m2 than normal-weight PWH. Results differed within classes and by outcome. Raltegravir and dolutegravir were consistently associated with greater weight gain than the other third agents. Tenofovir alafenamide was also associated with higher weight gain than tenofovir disoproxil or abacavir. CONCLUSIONS: After initiating cART, PWH with early presentation exhibited a small weight gain, whereas it was large among those with advanced presentation. The choice of ART should account for the risk of weight gain, especially for PWH who present with advanced disease and/or are obese.
