RESUMEN

BACKGROUND AND AIMS: The severity of liver injury and clinical outcomes in lean individuals with NAFLD is a subject of debate and very few studies have been performed in the general population. The aim of this study was to compare subject characteristics and mortality between lean and nonlean NAFLD in a community setting. APPROACH AND RESULTS: The study population included 169,303 participants from the nationwide Constances cohort. Subjects with excessive alcohol consumption, viral hepatitis, or other liver diseases were excluded and 137,206 subjects were analyzed. The diagnosis of NAFLD and fibrosis was performed using the Fatty Liver Index and the Forns Index. The median follow-up was 3.58 years. The prevalence of NAFLD was 5.3% (95% CI: 5.2-5.4) in lean subjects, while 16.3% (95% CI: 15.7-16.8) of NAFLD subjects were lean. Despite their better metabolic profile, the prevalence of advanced fibrosis was significantly higher in lean than in nonlean NAFLD (3.7% vs. 1.7%, respectively, p < 0.01). Among NAFLD subjects and after adjustment for demographics, metabolic risk factors and lifestyle, lean status was associated with advanced fibrosis (OR=1.26, 95% CI: 1.20-1.65, p = 0.005), an increased risk of liver-related events (adjusted HR=5.84, 95% CI: 4.03-8.46), chronic kidney disease (adjusted HR=2.49, 95% CI: 1.49-4.16), and overall mortality (adjusted HR=3.01, 95% CI: 2.21-4.11). Liver-related events and overall mortality were related to the severity of fibrosis, both in lean and nonlean NAFLD subjects, whatever the usual risk factors. CONCLUSION: This study in a large community-based cohort confirms that NAFLD in lean subjects is more severe for fibrosis, the progression of liver disease, chronic kidney disease, and overall mortality.

RESUMEN

Hepatitis B (HBV) is a major cause of global morbidity and mortality, and the leading cause of liver cancer worldwide. Significant advances have recently been made toward the development of a finite HBV treatment that achieves permanent loss of HBsAg and HBV DNA (so-called "HBV cure"), which could provide the means to eliminate HBV as a public health threat. However, the HBV cure is just one step toward achieving WHO HBV elimination targets by 2030, and much work must be done now to prepare for the successful implementation of the HBV cure. In this review, we describe the required steps to rapidly scale-up future HBV cure equitably. We present key actions required for successful HBV cure implementation, integrated within the World Health Organization (WHO) Global Health Sector Strategy (GHSS) 2022-2030 framework. Finally, we highlight what can be done now to progress toward the 2030 HBV elimination targets using available tools to ensure that we are preparing, but not waiting, for the cure.

RESUMEN

BACKGROUND: As the population of people with HIV ages, concerns over managing age-related comorbidities, polypharmacy, immune recovery, and drug-drug interactions while maintaining viral suppression have arisen. We present pooled TANGO and SALSA efficacy and safety results dichotomized by age (< 50 and ≥ 50 years). METHODS: Week 48 data from the open-label phase 3 TANGO and SALSA trials evaluating switch to once-daily dolutegravir/lamivudine (DTG/3TC) fixed-dose combination vs continuing current antiretroviral regimen (CAR) were pooled. Proportions of participants with HIV-1 RNA ≥ 50 and < 50 copies/mL (Snapshot, intention-to-treat exposed) and safety were analyzed by age category. Adjusted mean change from baseline in CD4 + cell count was assessed using mixed-models repeated-measures analysis. RESULTS: Of 1234 participants, 80% of whom were male, 29% were aged ≥ 50 years. Among those aged ≥ 50 years, 1/177 (< 1%) DTG/3TC participant and 3/187 (2%) CAR participants had HIV-1 RNA ≥ 50 copies/mL at 48 weeks; proportions with HIV-1 RNA < 50 copies/mL were high in both treatment groups (≥ 92%), consistent with overall efficacy and similar to observations in participants aged < 50 years (≥ 93%). Regardless of age category, CD4 + cell count increased or was maintained from baseline with DTG/3TC. Change from baseline in CD4 + /CD8 + ratio was similar across age groups and between treatment groups. One CAR participant aged < 50 years had confirmed virologic withdrawal, but no resistance was detected. In the DTG/3TC group, incidence of adverse events (AEs) was similar across age groups. Proportions of AEs leading to withdrawal were low and comparable between age groups. Although drug-related AEs were generally low, across age groups, drug-related AEs were more frequent in participants who switched to DTG/3TC compared with those who continued CAR. While few serious AEs were observed in both treatment groups, more were reported in participants aged ≥ 50 years vs < 50 years. CONCLUSIONS: Among individuals with HIV-1, switching to DTG/3TC maintained high rates of virologic suppression and demonstrated a favorable safety profile, including in those aged ≥ 50 years despite higher prevalence of concomitant medication use and comorbidities.

RESUMEN

BackgroundSome migrant men who have sex with men (MSM) acquire HIV in France.AimsWe investigated, in migrant MSM receiving HIV care in France, the (i) rate of post-migration-HIV acquisition in France, (ii) delay between arrival and HIV acquisition and (iii) factors affecting HIV acquisition within 1 year after migration.MethodsThis cross-sectional study focused on ≥ 18-year-old MSM born outside France, receiving HIV care in the Paris region. Information on migration history, socioeconomic condition, sexual activity, and health was collected in May 2021-June 2022 through self-administered questionnaires and medical records. Post-migration-HIV-acquisition rate and delay between arrival in France and HIV acquisition were estimated from biographical data and CD4+ T-cell counts. Predictors of HIV acquisition within 1 year after migration were determined using logistic regression.ResultsOverall post-migration HIV-acquisition rate was 61.7% (715/1,159; 95%CI: 61.2-62.2), ranging from 40.5% (95%CI: 39.6-41.6) to 85.4% (95%CI: 83.9-86.0) in participants from Latin America and North Africa. Among post-migration-HIV acquisitions, those within 1 year after migration represented 13.1% overall (95%CI: 11.6-14.6), being highest in participants from sub-Saharan Africa (25%; 95%CI: 21.5-28.3). Participants ≥ 15-years old at migration, with post-migration-acquired HIV, had a 7.5-year median interval from arrival in France to HIV acquisition (interquartile range (IQR): 3.50-14.75). Older age at arrival, region of origin (sub-Saharan Africa and Asia), degree of social disadvantage and numbers of sexual partners were independently associated with acquiring HIV within 1 year in France.ConclusionOur findings may guide HIV prevention policies for most vulnerable migrants to Europe.

RESUMEN

BACKGROUND: Initiating same-day ART for newly HIV-diagnosed individuals reduces secondary HIV transmissions and the risk of them being lost to follow-up between diagnosis and initiation of ART. METHODS: The FAST study was a national, prospective, single-arm study assessing the efficacy, safety and feasibility of bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) in a same-day initiation model. ART had to be started on the first medical appointment, before any laboratory results were available. Participants completed a self-administered questionnaire at each visit including a HIV anxiety 5-point Likert scale. The primary outcome was the proportion of participants in the ITT population with plasma HIV RNA (pVL) < 50 copies/mL at Week (W) 24 using the FDA Snapshot algorithm. RESULTS: Overall, 112 participants were included in the ITT population. During follow-up, seven participants discontinued the study drug but remained on the study, and seven others discontinued follow-up. According to FDA Snapshot analysis, at W24 and W48, 90/112, (80.4%; 95% CI: 71.8-87.3) and 95/112 (84.8%; 95% CI: 76.8-90.9) of participants achieved pVL < 50 copies/mL, respectively. The protocol-defined virological failure (PDVF, 2 consecutive pVL ≥ 50 copies/mL as of W24) was observed in 11/112 (9.8%) at W24 and 14/112 (12.5%) at W48. No emergent resistance-associated mutation was detected in those with PDVF at W24 and W48. BIC/FTC/TAF was well tolerated through to W48, with a low incidence of grade 3-4 adverse events (15/100 person-years). Patient opinion of same-day treatment initiation and continuing BIC/FTC/TAF was very favourable. CONCLUSIONS: These results suggest that BIC/FTC/TAF is safe, effective and well accepted for same-day initiation.

RESUMEN

BACKGROUND AND AIMS: The association between birth weight (BW) and metabolic outcomes has been described since the 1980s but NAFLD has been rarely studied. This study aimed to investigate the association between BW and NAFLD occurrence in adult subjects. APPROACH AND RESULTS: The study population consisted of participants from the French nationwide Constances cohort from 2012 to 2019. Participants with a history of chronic viral hepatitis or excessive alcohol consumption were excluded. Noninvasive diagnosis of NAFLD and fibrosis was performed using a combination of the Fatty Liver Index (FLI) and the Forns Index. The relationship between BW and NAFLD was analyzed with a sex-stratified logistic regression model adjusted for sociodemographic parameters, lifestyle, and birth term, whereas liver fibrosis was analyzed with a sex-stratified linear regression model. In total, 55,034 individuals with reliable BW were included (43% men, mean age: 38 years). NAFLD (FLI ≥ 60) was present in 5530 individuals (10%). Multivariate logistic regression showed a significant U-shaped relationship between BW and NAFLD, with no significant interaction with sex. A significant and slightly decreasing association was found between BW and Forns Index (ß = -0.05; p = 0.04). Premature birth (OR, 1.23; 95% CI, 1.03-1.48 for birth between 33 and 37 weeks versus ≥ 37 weeks) was associated with NAFLD, with a significant direct effect of premature birth, and without an indirect effect of low BW in mediation analysis. Forns Index was not significantly higher in participants with preterm birth compared to full-term birth. CONCLUSIONS: This large prospective adult-based cohort confirms the relationship between BW and NAFLD occurrence.

RESUMEN

BACKGROUND: The impact of non-alcoholic fatty liver disease (NAFLD) on morbidity and mortality has yet to be documented at the general population level. This study aimed to assess whether NAFLD was associated with morbidities and mortality and to estimate its impact on health status and mortality. METHODS: The study population consisted of 137 206 participants from Constances cohort. Non-invasive diagnosis of NAFLD and advanced fibrosis was performed using the fatty liver index and Forns index, respectively. Constances data were linked to health care and hospitalization data to identify liver-related events, cardiovascular diseases (CVD), extrahepatic cancers (EHC), chronic kidney disease (CKD) and all-cause mortality. RESULTS: The prevalence of NAFLD was 18.3% in subjects without other chronic liver diseases, among whom 2.7% had fibrosis. NAFLD after IPTW-weighted remained associated with an increased risk of death (HR 1.26, 95% CI 1.01-1.57), hepatic-related complications (HR 2.48, 95% CI 1.99-3.29), CVD (HR 1.42, 95% CI 1.30-1.55), EHC (HR 1.11, 95% CI 1.01-1.28) and CKD (HR 1.81, 95% CI 1.53-2.07) compared to those without chronic liver diseases risk factors (Non-NAFLD). In the trend analysis over the study period of inclusion and compared to Non-NAFLD, NAFLD has shown a fastest growing cause of hepatic events (HR 1.38, 95% CI 1.07-1.76 per year), CVD (HR 1.08, 95% CI 1.03-1.12), CKD (HR 1.16, 95% CI 1.07-1.25), and death (HR 1.39, 95% CI 1.39-1.50). CONCLUSION: This large community-based cohort showed that NAFLD was associated with excess morbidity and mortality and demonstrated a fastest-growing trend.

RESUMEN

OBJECTIVES: People who inject drugs (PWID) are at a high risk of hepatitis C virus (HCV) infection. HCV cure is associated with improved patient-reported outcomes (PROs), but there are little data among PWID. This study aimed to assess the change in PROs during and after HCV direct-acting antiviral (DAA) treatment. METHODS: This analysis used data from 2 clinical trials of DAA treatment in PWID. PROs assessed included health-related quality of life, social functioning, psychological distress, housing, and employment. Generalized estimating equations and group-based trajectory modeling were used to assess changes in PROs over time. RESULTS: No significant changes in the 3-level version of EQ-5D scores, EQ visual analogue scale scores, social functioning, psychological distress, and housing were observed over the 108-week study period. There was a significant increase in the proportion of participants employed (18% [95% confidence interval (CI) 12%-23%] at baseline to 28% [95% CI 19%-36%] at the end of the study). Participants were more likely to be employed at 24 weeks and 108 weeks after commencing treatment. Having stable housing increased the odds of being employed (odds ratio 1.70; 95% CI 1.00-2.90). The group-based trajectory modeling demonstrated that most outcomes remained stable during and after DAA treatment. CONCLUSIONS: Although no significant improvement was identified in health-related quality of life after HCV DAA treatment, there was a modest but significant increase in employment during study follow-up. The study findings support the need for multifaceted models of HCV care for PWID addressing a range of issues beyond HCV treatment to improve quality of life.

RESUMEN

HIV post- exposure prophylaxis (PEP) is a prevention tool for individuals with a recent potential exposure to HIV. Doravirine has been available since 2019 in combination with tenofovir disoproxil fumarate and lamivudine and has not been evaluated as a PEP. DOR/3TC/TDF is our department's most commonly prescribed PEP treatment since 2021. This study evaluates the completion rate of the DOR/3TC/TDF as compared to EVG/c/FTC/TAF for PEP, which was the regimen prescribed until 2020 in our hospital.This retrospective observational study was conducted between January 2020 and September 2021. The subjects included consecutively were adults who consulted for an HIV sexual exposure accident and for whom DOR/3TC/TDF in 2021 or EVG/c/FTC/TAF in 2020 was prescribed. The outcomes were the completion rate to the end of treatment (28 days), the seroconversion rate, and the description of side effects.During the study period, 311 people were included: 140 treated with DOR/3TC/TDF and 171 treated with EVGc/FTC/TAF. Considering subjects with a follow-up visit, the completion rate was 96.8% (90/93) in the DOR/3TC/TDF group, and 94.6% (123/130) in the EVG/c/FTC/TAF group (p-value: 0.53). The number of people lost to follow-up was nearly equivalent in both groups: 27.1% (38/140) in the DOR/3TC/TDF group and 23.4% (40/171) in the EVG/c/FTC/TAF group (p-value: 0.45). A side effect was described for 38% (36/94) in the DOR/3TC/TDF group, and 29.7% (38/128) in the EVG/c/FTC/TAF group. No cases of seroconversion were observed.DOR/3TC/TDF appears to have a similar safety profile to EVG/c/FTC/TAF. Due to its lower cost, it seems to be a treatment option for consideration in the context of HIV-exposure accidents.

RESUMEN

BACKGROUND: Baricitinib has shown efficacy in hospitalized patients with COVID-19, but no placebo-controlled trials have focused specifically on severe/critical COVID, including vaccinated participants. METHODS: Bari-SolidAct is a phase-3, multicentre, randomised, double-blind, placebo-controlled trial, enrolling participants from June 3, 2021 to March 7, 2022, stopped prematurely for external evidence. Patients with severe/critical COVID-19 were randomised to Baricitinib 4 mg once daily or placebo, added to standard of care. The primary endpoint was all-cause mortality within 60 days. Participants were remotely followed to day 90 for safety and patient related outcome measures. RESULTS: Two hundred ninety-nine patients were screened, 284 randomised, and 275 received study drug or placebo and were included in the modified intent-to-treat analyses (139 receiving baricitinib and 136 placebo). Median age was 60 (IQR 49-69) years, 77% were male and 35% had received at least one dose of SARS-CoV2 vaccine. There were 21 deaths at day 60 in each group, 15.1% in the baricitinib group and 15.4% in the placebo group (adjusted absolute difference and 95% CI - 0.1% [- 8·3 to 8·0]). In sensitivity analysis censoring observations after drug discontinuation or rescue therapy (tocilizumab/increased steroid dose), proportions of death were 5.8% versus 8.8% (- 3.2% [- 9.0 to 2.7]), respectively. There were 148 serious adverse events in 46 participants (33.1%) receiving baricitinib and 155 in 51 participants (37.5%) receiving placebo. In subgroup analyses, there was a potential interaction between vaccination status and treatment allocation on 60-day mortality. In a subsequent post hoc analysis there was a significant interaction between vaccination status and treatment allocation on the occurrence of serious adverse events, with more respiratory complications and severe infections in vaccinated participants treated with baricitinib. Vaccinated participants were on average 11 years older, with more comorbidities. CONCLUSION: This clinical trial was prematurely stopped for external evidence and therefore underpowered to conclude on a potential survival benefit of baricitinib in severe/critical COVID-19. We observed a possible safety signal in vaccinated participants, who were older with more comorbidities. Although based on a post-hoc analysis, these findings warrant further investigation in other trials and real-world studies. Trial registration Bari-SolidAct is registered at NCT04891133 (registered May 18, 2021) and EUClinicalTrials.eu ( 2022-500385-99-00 ).

RESUMEN

BACKGROUND: Extended-spectrum ß-lactamase-producing Enterobacterales (ESBL-E) represent a major threat to public health. Little is known on their potential for sexual transmission. METHODS: We recruited individuals at a sexually transmitted infection and human immunodeficiency virus (HIV) outpatient clinic in Paris, France, in whom we evaluated the prevalence of ESBL-E intestinal carriage and, among those testing positive, the proportion with clearance 6 months thereafter. We compared carriage prevalence between groups using logistic regression adjusted for age, geographic origin, travel outside Europe, and antibiotic use in the past 6 months. RESULTS: A total of 2157 individuals participated, of whom 226 (10.5%) were ESBL-E carriers. The proportions of ESBL-E carriers varied across sexual groups and were as follows: HIV-negative men who have sex with men (MSM) and who were on preexposure prophylaxis (PrEP), 16.3% (41 of 251); HIV-negative MSM not on PrEP, 9.7% (47 of 487); HIV-positive MSM, 12.2% (61 of 500); HIV-negative men who have sex exclusively with women, 10.0% (44 of 439); and HIV-negative women who have sex with men, 6.9% (n = 33 of 480). After adjustment, ESBL-E prevalence was significantly higher in HIV-negative MSM on PrEP (P < .001) and HIV-positive MSM (P = .01) than in women who have sex with men. A higher number of sexual partners in the past 6 months was associated with ESBL-E carriage after adjustment (P = .004). Escherichia coli sequence type 14 and blaSHV-12-producing ESBL-E were observed only in MSM. Of 102 individuals with ESBL-E returning for testing, 26 (25%) had carriage at 6 months. CONCLUSION: ESBL-E carriage is more frequent in MSM undergoing PrEP or living with HIV and with increasing number of sexual partners. More research is warranted to understand the consequences of ESBL-E carriage in these populations and how transmission can be reduced.

RESUMEN

BACKGROUND: In individuals living with human immunodeficiency virus (HIV) and hepatitis B virus (HBV), widespread tenofovir (TDF)-containing antiretroviral therapy (ART) has led to substantial decreases in HBV-DNA and HIV-RNA detection. However, the links between viral replication, liver fibrosis, and mortality remain unclear. METHODS: A total of 300 individuals living with HIV-HBV and undergoing ART were prospectively followed. Virological and clinical data were obtained at baseline and every 6-12 months. We quantified the associations between HBV-DNA, HIV-RNA, and liver fibrosis with risk of all-cause mortality using a joint longitudinal survival model. Viral detection, viral loads, and time-averaged cumulative viral loads of HIV and HBV were modeled as 3 separate exposures. RESULTS: During a median of 10.5 years (interquartile range, 4.0-14.6), the proportion undergoing TDF-containing ART (baseline = 18.7%, end of follow-up = 79.1%) and with undetectable HBV-DNA (baseline = 36.7%, end of follow-up = 94.8%) substantially increased. 42 participants died (incidence rate = 1.30/100 person-years, 95% confidence interval [CI] = .96-1.76). The leading causes of death were non-AIDS/non-liver-related malignancies (28.6%), followed by liver-related (16.7%), AIDS-related (16.7%), and other (16.7%). All-cause mortality was associated with HBV-DNA viral load (adjusted hazards ratio [aHR] per log10 IU/mL = 1.41, 95% CI = 1.04-1.93, P = .03) or time-averaged cumulative HBV-DNA (aHR per log10 copy-years = 1.37, 95% CI = 1.03-1.83, P = .03), but not undetectable HBV-DNA. Advanced liver fibrosis at baseline was also associated with increased mortality rates (aHR = 2.35, 95% CI = 1.16-4.76, P = .02). No significant association between HIV-RNA replication and mortality was observed. CONCLUSIONS: Concurrent and historical HBV replication and liver fibrosis are important drivers of all-cause mortality in largely TDF-treated individuals living with HIV-HBV, despite one-fifth of deaths being liver-related. HBV-DNA and liver fibrosis remain important prognostic indicators for this patient population.

RESUMEN

OBJECTIVES: Severe COVID-19 is associated with exaggerated complement activation. We assessed the efficacy and safety of avdoralimab (an anti-C5aR1 mAb) in severe COVID-19. DESIGN: FOR COVID Elimination (FORCE) was a double-blind, placebo-controlled study. SETTING: Twelve clinical sites in France (ICU and general hospitals). PATIENTS: Patients receiving greater than or equal to 5 L oxygen/min to maintain Sp o2 greater than 93% (World Health Organization scale ≥ 5). Patients received conventional oxygen therapy or high-flow oxygen (HFO)/noninvasive ventilation (NIV) in cohort 1; HFO, NIV, or invasive mechanical ventilation (IMV) in cohort 2; and IMV in cohort 3. INTERVENTIONS: Patients were randomly assigned, in a 1:1 ratio, to receive avdoralimab or placebo. The primary outcome was clinical status on the World Health Organization ordinal scale at days 14 and 28 for cohorts 1 and 3, and the number of ventilator-free days at day 28 (VFD28) for cohort 2. MEASUREMENTS AND MAIN RESULTS: We randomized 207 patients: 99 in cohort 1, 49 in cohort 2, and 59 in cohort 3. During hospitalization, 95% of patients received glucocorticoids. Avdoralimab did not improve World Health Organization clinical scale score on days 14 and 28 (between-group difference on day 28 of -0.26 (95% CI, -1.2 to 0.7; p = 0.7) in cohort 1 and -0.28 (95% CI, -1.8 to 1.2; p = 0.6) in cohort 3). Avdoralimab did not improve VFD28 in cohort 2 (between-group difference of -6.3 (95% CI, -13.2 to 0.7; p = 0.96) or secondary outcomes in any cohort. No subgroup of interest was identified. CONCLUSIONS: In this randomized trial in hospitalized patients with severe COVID-19 pneumonia, avdoralimab did not significantly improve clinical status at days 14 and 28 (funded by Innate Pharma, ClinicalTrials.gov number, NCT04371367).

RESUMEN

BACKGROUND: Whether integrase strand transfer inhibitors (INSTIs) can decrease HIV-1 DNA levels more rapidly than boosted PIs during primary HIV-1 infection (PHI) is unknown. We hypothesized that once-daily dolutegravir/tenofovir/emtricitabine could reduce the viral reservoir through rapid viral replication control further than once-daily darunavir/cobicistat/tenofovir/emtricitabine. METHODS: The OPTIPRIM2-ANRS 169 study was a randomized (1:1), open-label, multicentre trial in adults with ≤5 or ≤3 HIV antibodies detected, respectively, by western blot or immunoblot in the last 10 days. The primary endpoint was total HIV-1 DNA levels in PBMCs at Week 48 (W48) adjusted for baseline levels. The main secondary endpoint was HIV-1 RNA level decrease. RESULTS: Between April 2017 and August 2018, 101 patients were included from 31 hospitals. Most patients were men (93%), the median age was 36 years and 17% were Fiebig stage ≤3. The median (IQR) plasma HIV-1 RNA and DNA levels were, respectively, 5.8 (5.0-6.6) and 3.87 (3.52-4.15) log10 copies/million PBMCs. The median (IQR) decreases in HIV-1 DNA levels at W48 were -1.48 (-1.74 to -1.06) and -1.39 (-1.55 to -0.98) log10 copies/million PBMCs in the dolutegravir and darunavir/cobicistat groups, respectively (P = 0.52). Plasma HIV-1 RNA levels were <50 copies/mL in 24% versus 0% of patients in the dolutegravir and darunavir/cobicistat groups at W4, 55% versus 2% at W8, 67% versus 17% at W12, and 94% versus 90% at W48, respectively. CONCLUSIONS: Dolutegravir-based and darunavir-based regimens initiated during PHI strongly and similarly decreased the blood reservoir size. Considering the rapid viral suppression during a period of high HIV-1 transmission risk, dolutegravir-based regimens are a major first-line option.

RESUMEN

BACKGROUND: Dolutegravir is a widespread integrase strand-transfer inhibitor (INSTI) recommended for treatment of primary HIV infection (PHI). PHI is a high-risk stage for sexual transmission because of the high viral load in semen. Yet dolutegravir concentrations in semen are lower than in blood during chronic treatment. OBJECTIVES: To compare the kinetics of HIV-RNA and total HIV-DNA in the genital compartment in subjects receiving either tenofovir/emtricitabine/dolutegravir or tenofovir/emtricitabine/darunavir/cobicistat as a first-line combined ART (cART) at the time of PHI. PATIENTS AND METHODS: Eighteen subjects receiving tenofovir/emtricitabine/dolutegravir and 19 receiving tenofovir/emtricitabine/darunavir/cobicistat enrolled in the ANRS169 OPTIPRIM-2 trial participated in the genital substudy. RESULTS: Between week (W) 0 and W2 HIV-RNA in seminal plasma (SP) decreased by 1 log10 copies/mL. Undetectable SP HIV-RNA was achieved in similar proportions between the two regimens at each timepoint. Overall, eight patients still presented detectable HIV-RNA or HIV-DNA in semen at W48; 15.4% and 28.6% presented detectable HIV-RNA and 9.1% and 14.3% presented detectable HIV-DNA in dolutegravir- and darunavir-based cART groups, respectively, with no significant difference. CONCLUSIONS: For the first time, to the best of our knowledge, we showed that a dolutegravir-based regimen initiated as soon as PHI reduces HIV-RNA and HIV-DNA with no difference compared with a control group receiving a darunavir-based regimen. Although the viral purge in semen seems longer after treatment in PHI than CHI, due to high viral loads, early dolutegravir-based treatment initiation permits a major decay of both viral particles and infected cells in semen, efficiently reducing the high risk of transmission during PHI.

RESUMEN

Anti-CD20 monoclonal antibodies are widely used for the treatment of hematological malignancies or autoimmune disease but may be responsible for a secondary humoral deficiency. In the context of COVID-19 infection, this may prevent the elicitation of a specific SARS-CoV-2 antibody response. We report a series of 17 consecutive patients with profound B-cell lymphopenia and prolonged COVID-19 symptoms, negative immunoglobulin G (IgG)-IgM SARS-CoV-2 serology, and positive RNAemia measured by digital polymerase chain reaction who were treated with 4 units of COVID-19 convalescent plasma. Within 48 hours of transfusion, all but 1 patient experienced an improvement of clinical symptoms. The inflammatory syndrome abated within a week. Only 1 patient who needed mechanical ventilation for severe COVID-19 disease died of bacterial pneumonia. SARS-CoV-2 RNAemia decreased to below the sensitivity threshold in all 9 evaluated patients. In 3 patients, virus-specific T-cell responses were analyzed using T-cell enzyme-linked immunospot assay before convalescent plasma transfusion. All showed a maintained SARS-CoV-2 T-cell response and poor cross-response to other coronaviruses. No adverse event was reported. Convalescent plasma with anti-SARS-CoV-2 antibodies appears to be a very promising approach in the context of protracted COVID-19 symptoms in patients unable to mount a specific humoral response to SARS-CoV-2.

RESUMEN

BACKGROUND: The epidemiology and natural history of non-alcoholic fatty liver disease (NAFLD) in diabetes have been mainly investigated in the hospital setting. The goal of this study was to evaluate the characteristics of NAFLD and its impact on morbidity and mortality in type 2 diabetic subjects in a community setting. METHOD: This study included 199 341 participants in the nationwide Constances cohort. After patients with excessive alcohol consumption, viral hepatitis or other causes of liver disease were excluded, 164 285 were analysed and 8386 (5.3%) were considered to have type 2 diabetes. The non-invasive diagnosis of NAFLD and advanced fibrosis was made using a combination of the fatty liver index and Forns index. Median follow-up was 2.5 years. RESULTS: Diabetes increased the risk of NAFLD by sixfold (adjusted OR 6.05, 95% CI 5.68-6.45) and the risk of advanced fibrosis by 3.76-fold (aOR 3.76, 95% CI 2.87-4.91) in NAFLD subjects. After controlling for confounders, the presence of NAFLD in diabetic subjects was associated with an increased risk of severe liver-related events (aHR 2.53, 95% CI 1.36-4.69), cardiovascular disease (CVD, aHR 2.71, 95% CI 1.72-4.26) and overall mortality (aHR 2.91, 95% CI 1.53-5.53). The risk of hepatic and extrahepatic complications in diabetic subjects with NAFLD significantly increased with the severity of fibrosis (P < .05). CONCLUSION: This prospective, longitudinal study in a large community-based cohort provides real-world evidence of the risk for NAFLD and advanced fibrosis in diabetes, and its impact on liver disease progression, diabetes-related complications such as CVD, and overall mortality. These data could be used to estimate real clinical and economic burden of NAFLD in diabetic subjects.

RESUMEN

BACKGROUND: The relationship between the severity of NAFLD and extra-hepatic events such as cardiovascular disease (CVD), extra-hepatic cancer (EHC) or chronic kidney diseases (CKD) has not been clearly investigated in the general population. AIMS: The aim of this study was to assess whether the severity of fibrosis in NAFLD subjects was associated with extra-hepatic diseases based on noninvasive markers in a large population-based cohort. METHODS: The study population included a cohort of 118,664 participants from the nationwide CONSTANCES cohort. After excluding individuals with excessive alcohol consumption and other causes of liver disease, 102,344 were included. The noninvasive diagnosis of NAFLD and fibrosis was performed using a combination of the Fatty Liver Index (FLI) and the Forns Index. The history of CVD or EHC was recorded by a physician, and CKD was defined by a glomerular filtration rate < 60 ml/mn. RESULTS: The prevalence of NAFLD (FLI > 60) was 18.2%, 10% with mild fibrosis (Forns Index < 4.2), 7.7% with intermediate fibrosis (Forns Index 4.2-6.9), and 0.4% with advanced fibrosis (Forns Index > 6.9). The prevalence of CVD, EHC, or CKD increased significantly with the severity of fibrosis (p < 0.0001). When adjusted for demographic, metabolic risk factors, and smoking, NAFLD with intermediate or advanced fibrosis remained associated with CVD (OR 1.36, p < 0.0001 and OR 3.07, p < 0.0001, respectively), EHC (OR 1.24, p = 0.001 and OR 1.64, p = 0.004, respectively), and CKD (OR 1.18, p = 0.03 and OR 2.09, p < 0.0001, respectively). CONCLUSIONS: In a large adult population-based cohort, there is a dose-dependent relationship between the severity of fibrosis and CVD, EHC, or CKD in NAFLD subjects.

RESUMEN

BACKGROUND: Although direct-acting antivirals (DAA) have become standard care for patients with chronic hepatitis C worldwide, there is no evidence for their value for money in sub-Saharan Africa. We assessed the cost-effectiveness of four sofosbuvir-based regimens recommended by the World Health Organization (WHO) in Cameroon, Côte d'Ivoire and Senegal. METHODS: Using modelling, we simulated chronic hepatitis C progression with and without treatment in hypothetical cohorts of patients infected with the country's predominant genotypes (1, 2 and 4) and without other viral coinfections, history of liver complication or hepatocellular carcinoma. Using the status-quo 'no DAA treatment' as a comparator, we assessed four regimens: sofosbuvir-ribavirin, sofosbuvir-ledipasvir (both recommended in WHO 2016 guidelines and assessed in the TAC pilot trial conducted in Cameroon, Côte d'Ivoire and Senegal), sofosbuvir-daclatasvir and sofosbuvir-ledipasvir (two pangenotypic regimens recommended in WHO 2018 guidelines). DAA effectiveness, costs and utilities were mainly estimated using data from the TAC pilot trial. Secondary data from the literature was used to estimate disease progression probabilities with and without treatment. We considered two DAA pricing scenarios: S1) originator prices; S2) generic prices. Uncertainty was addressed using probabilistic and deterministic sensitivity analyses and cost-effectiveness acceptability curves. RESULTS: With slightly higher effectiveness and significantly lower costs, sofosbuvir/velpatasvir was the preferred DAA regimen in S1 with incremental cost-effectiveness ratios (ICERs) ranging from US$526 to US$632/QALY. At the cost-effectiveness threshold (CET) of 0.5 times the 2017 country's per-capita gross domestic product (GDP), sofosbuvir/velpatasvir was only cost-effective in Senegal (probability > 95%). In S2 at generic prices, sofosbuvir/daclatasvir was the preferred regimen due to significantly lower costs. ICERs ranged from US$139 to US$216/QALY according to country i.e. a 95% probability of being cost-effective. Furthermore, this regimen was cost-effective (probability> 95%) for all CET higher than US$281/QALY, US$223/QALY and US$195/QALY in Cameroon, Côte d'Ivoire and Senegal, respectively, corresponding to 0.14 (Côte d'Ivoire and Senegal) and 0.2 (Cameroon) times the country's per-capita GDP. CONCLUSIONS: Generic sofosbuvir/daclatasvir is very cost-effective for treating chronic hepatitis C in sub-Saharan Africa. Large-scale use of generics and an increase in national and international funding for hepatitis C treatment must be priorities for the HCV elimination agenda.
