Abstract: Summary: Background: Although immunomodulators have established benefit against the new coronavirus disease (COVID-19) in general, it is uncertain whether such agents improve outcomes without increasing the risk of secondary infections in the specific subgroup of previously immunocompromised patients. We assessed the effect of immunomodulators on outcomes of immunocompromised patients hospitalized for COVID-19. Methods: The protocol was prospectively registered with PROSPERO (CRD42022335397). MEDLINE, Cochrane Central Register of Controlled Trials and references of relevant articles were searched up to 01-06-2022. Authors of potentially eligible randomized controlled trials were contacted to provide data on immunocompromised patients randomized to immunomodulators vs control (i.e., placebo or standard-of-care). Findings: Eleven randomized controlled trials involving 397 immunocompromised patients hospitalized for COVID-19 were included. Ten trials had low risk of bias. There was no difference between immunocompromised patients randomized to immunomodulators vs control regarding mortality [30/182 (16.5%) vs 41/215 (19.1%); RR 0.93, 95% CI 0.61–1.41; p = 0.74], secondary infections (RR 1.00, 95% CI 0.64–1.58; p = 0.99) and change in World Health Organization ordinal scale from baseline to day 15 (weighed mean difference 0.27, 95% CI -0.09–0.63; p = 0.15). In subgroup analyses including only patients with hematologic malignancy, only trials with low risk of bias, only trials administering IL-6 inhibitors, or only trials administering immunosuppressants, there was no difference between comparators regarding mortality. Interpretation: Immunomodulators, compared to control, were not associated with harmful or beneficial outcomes, including mortality, secondary infections, and change in ordinal scale, when administered to immunocompromised patients hospitalized for COVID-19.

Abstract: Abstract Background We describe a frugal approach (focusing on needs, performance, and costs) to manage a massive influx of COVID-19 patients with acute hypoxemic respiratory failure (AHRF) using the Boussignac valve protected by a filter (“Filter Frugal CPAP”, FF-CPAP) in and out the ICU. Methods (1) A bench study measured the impact of two filters with different mechanical properties on CPAP performances, and pressures were also measured in patients. (2) Non-ICU healthcare staff working in COVID-19 intermediate care units were trained with a video tutorial posted on a massive open online course. (3) A clinical study assessed the feasibility and safety of using FF-CPAP to maintain oxygenation and manage patients out of the ICU during a massive outbreak. Results Bench assessments showed that adding a filter did not affect the effective pressure delivered to the patient. The resistive load induced by the filter variably increased the simulated patient’s work of breathing (6–34%) needed to sustain the tidal volume, depending on the filter’s resistance, respiratory mechanics and basal inspiratory effort. In patients, FF-CPAP achieved pressures similar to those obtained on the bench. The massive training tool provided precious information on the use of Boussignac FF-CPAP on COVID-19 patients. Then 85 COVID-19 patients with ICU admission criteria over a 1-month period were studied upon FF-CPAP initiation for AHRF. FF-CPAP significantly decreased respiratory rate and increased SpO2. Thirty-six (43%) patients presented with respiratory indications for intubation prior to FF-CPAP initiation, and 13 (36%) of them improved without intubation. Overall, 31 patients (36%) improved with FF-CPAP alone and 17 patients (20%) did not require ICU admission. Patients with a respiratory rate > 32 breaths/min upon FF-CPAP initiation had a higher cumulative probability of intubation (p

Abstract: Summary Background Patients with COVID-19 pneumonia can have increased inflammation and elevated cytokines, including interleukin (IL)-6, which might be deleterious. Thus, sarilumab, a high-affinity anti-IL-6 receptor antibody, might improve the outcome of patients with moderate-to-severe COVID-19 pneumonia. Methods We did a multicentric, open-label, Bayesian randomised, adaptive, phase 2/3 clinical trial, nested within the CORIMUNO-19 cohort, to test a superiority hypothesis. Patients 18 years or older hospitalised with COVID-19 in six French centres, requiring at least 3L/min of oxygen but without ventilation assistance and a WHO Clinical Progression Scale [CPS] score of 5 were enrolled. Patients were randomly assigned (1:1) via a web-based system, according to a randomisation list stratified on centre and with blocks randomly selected among 2 and 4, to receive usual care plus 400 mg of sarilumab intravenously on day 1 and on day 3 if clinically indicated (sarilumab group) or usual care alone (usual care group). Primary outcomes were the proportion of patients with WHO-CPS scores greater than 5 on the 10-point scale on day 4 and survival without invasive or non-invasive ventilation at day 14. This completed trial is closed to new participants and is registered with ClinicalTrials.gov , NCT04324073 . Findings 165 patients were recruited from March 27 to April 6, 2020, and 148 patients were randomised (68 patients to the sarilumab group and 80 to the usual care group) and followed up for 90 days. Median age was 61·7 years [IQR 53·0–71·1] in the sarilumab group and 62·8 years [56·0–71·7] in the usual care group. In the sarilumab group 49 (72%) of 68 were men and in the usual care group 59 (78%) of 76 were men. Four patients in the usual care group withdrew consent and were not analysed. 18 (26%) of 68 patients in the sarilumab group had a WHO-CPS score greater than 5 at day 4 versus 20 (26%) of 76 in the usual care group (median posterior absolute risk difference 0·2%; 90% credible interval [CrI] −11·7 to 12·2), with a posterior probability of absolute risk difference greater than 0 of 48·9%. At day 14, 25 (37%) patients in the sarilumab and 26 (34%) patients in the usual care group needed ventilation or died, (median posterior hazard ratio [HR] 1·10; 90% CrI 0·69–1·74) with a posterior probability HR greater than 1 of 37·4%. Serious adverse events occurred in 27 (40%) patients in the sarilumab group and 28 (37%) patients in the usual care group (p=0·73). Interpretation Sarilumab treatment did not improve early outcomes in patients with moderate-to-severe COVID-19 pneumonia. Further studies are warranted to evaluate the effect of sarilumab on long-term survival. Funding Assistance publique—Hopitaux de Paris

Abstract: Summary Background Shortening the duration of antibiotic therapy for patients admitted to hospital with community-acquired pneumonia should help reduce antibiotic consumption and thus bacterial resistance, adverse events, and related costs. We aimed to assess the need for an additional 5-day course of β-lactam therapy among patients with community-acquired pneumonia who were stable after 3 days of treatment. Methods We did this double-blind, randomised, placebo-controlled, non-inferiority trial (the Pneumonia Short Treatment [PTC]) in 16 centres in France. Adult patients (aged ≥18 years) admitted to hospital with moderately severe community-acquired pneumonia (defined as patients admitted to a non-critical care unit) and who met prespecified clinical stability criteria after 3 days of treatment with β-lactam therapy were randomly assigned (1:1) to receive β-lactam therapy (oral amoxicillin 1 g plus clavulanate 125 mg three times a day) or matched placebo for 5 extra days. Randomisation was done using a web-based system with permuted blocks with random sizes and stratified by randomisation site and Pneumonia Severity Index score. Participants, clinicians, and study staff were masked to treatment allocation. The primary outcome was cure 15 days after first antibiotic intake, defined by apyrexia (temperature ≤37·8°C), resolution or improvement of respiratory symptoms, and no additional antibiotic treatment for any cause. A non-inferiority margin of 10 percentage points was chosen. The primary outcome was assessed in all patients who were randomly assigned and received any treatment (intention-to-treat [ITT] population) and in all patients who received their assigned treatment (per-protocol population). Safety was assessed in the ITT population. This study is registered with ClinicalTrials.gov, NCT01963442, and is now complete. Findings Between Dec 19, 2013, and Feb 1, 2018, 706 patients were assessed for eligibility, and after 3 days of β-lactam treatment, 310 eligible patients were randomly assigned to receive either placebo (n=157) or β-lactam treatment (n=153). Seven patients withdrew consent before taking any study drug, five in the placebo group and two in the β-lactam group. In the ITT population, median age was 73·0 years (IQR 57·0–84·0) and 123 (41%) of 303 participants were female. In the ITT analysis, cure at day 15 occurred in 117 (77%) of 152 participants in the placebo group and 102 (68%) of 151 participants in the β-lactam group (between-group difference of 9·42%, 95% CI −0·38 to 20·04), indicating non-inferiority. In the per-protocol analysis, 113 (78%) of 145 participants in the placebo treatment group and 100 (68%) of 146 participants in the β-lactam treatment group were cured at day 15 (difference of 9·44% [95% CI −0·15 to 20·34]), indicating non-inferiority. Incidence of adverse events was similar between the treatment groups (22 [14%] of 152 in the placebo group and 29 [19%] of 151 in the β-lactam group). The most common adverse events were digestive disorders, reported in 17 (11%) of 152 patients in the placebo group and 28 (19%) of 151 patients in the β-lactam group. By day 30, three (2%) patients had died in the placebo group (one due to bacteraemia due to Staphylococcus aureus, one due to cardiogenic shock after acute pulmonary oedema, and one due to heart failure associated with acute renal failure) and two (1%) in the β-lactam group (due to pneumonia recurrence and possible acute pulmonary oedema). Interpretation Among patients admitted to hospital with community-acquired pneumonia who met clinical stability criteria, discontinuing β-lactam treatment after 3 days was non-inferior to 8 days of treatment. These findings could allow substantial reduction of antibiotic consumption. Funding French Ministry of Health.

Abstract: Background We describe a frugal approach (focusing on needs, performance, and costs) to manage a massive influx of COVID-19 patients with acute hypoxemic respiratory failure (AHRF) using the Boussignac valve protected by a filter (“Filter Frugal CPAP”, FF-CPAP) in and out the ICU. Methods (1) A bench study measured the impact of two filters with different mechanical properties on CPAP performances, and pressures were also measured in patients. (2) Non-ICU healthcare staff working in COVID-19 intermediate care units were trained with a video tutorial posted on a massive open online course. (3) A clinical study assessed the feasibility and safety of using FF-CPAP to maintain oxygenation and manage patients out of the ICU during a massive outbreak. Results Bench assessments showed that adding a filter did not affect the effective pressure delivered to the patient. The resistive load induced by the filter variably increased the simulated patient’s work of breathing (6–34%) needed to sustain the tidal volume, depending on the filter’s resistance, respiratory mechanics and basal inspiratory effort. In patients, FF-CPAP achieved pressures similar to those obtained on the bench. The massive training tool provided precious information on the use of Boussignac FF-CPAP on COVID-19 patients. Then 85 COVID-19 patients with ICU admission criteria over a 1-month period were studied upon FF-CPAP initiation for AHRF. FF-CPAP significantly decreased respiratory rate and increased SpO2. Thirty-six (43%) patients presented with respiratory indications for intubation prior to FF-CPAP initiation, and 13 (36%) of them improved without intubation. Overall, 31 patients (36%) improved with FF-CPAP alone and 17 patients (20%) did not require ICU admission. Patients with a respiratory rate > 32 breaths/min upon FF-CPAP initiation had a higher cumulative probability of intubation (p Conclusion Adding a filter to the Boussignac valve does not affect the delivered pressure but may variably increase the resistive load depending on the filter used. Clinical assessment suggests that FF-CPAP is a frugal solution to provide a ventilatory support and improve oxygenation to numerous patients suffering from AHRF in the context of a massive outbreak.

Abstract: International audience; Background: Patients with COVID-19 pneumonia have an excess of inflammation and increased concentrations of cytokines including interleukin-1 (IL-1). We aimed to determine whether anakinra, a recombinant human IL-1 receptor antagonist, could improve outcomes in patients in hospital with mild-to-moderate COVID-19 pneumonia.Methods: In this multicentre, open-label, Bayesian randomised clinical trial (CORIMUNO-ANA-1), nested within the CORIMUNO-19 cohort, we recruited patients from 16 University hospitals in France with mild-to-moderate COVID-19 pneumonia, severe acute respiratory syndrome coronavirus 2 infection confirmed by real-time RT-PCR, requiring at least 3 L/min of oxygen by mask or nasal cannula but without ventilation assistance, a score of 5 on the WHO Clinical Progression Scale (WHO-CPS), and a C-reactive protein serum concentration of more than 25 mg/L not requiring admission to the intensive care unit at admission to hospital. Eligible patients were randomly assigned (1:1) using a web-based secure centralised system, stratified by centre and blocked with varying block sizes (randomly of size two or four), to either usual care plus anakinra (200 mg twice a day on days 1-3, 100 mg twice on day 4, 100 mg once on day 5) or usual care alone. Usual care was provided at the discretion of the site clinicians. The two coprimary outcomes were the proportion of patients who had died or needed non-invasive or mechanical ventilation by day 4 (ie, a score of >5 on the WHO-CPS) and survival without need for mechanical or non-invasive ventilation (including high-flow oxygen) at day 14. All analyses were done on an intention-to-treat basis. The trial is registered with ClinicalTrials.gov, NCT04341584, and is now closed to accrual.Findings: Between April 8 and April 26, 2020, we screened 153 patients. The study was stopped early following the recommendation of the data and safety monitoring board, after the recruitment of 116 patients: 59 were assigned to the anakinra group, and 57 were assigned to the usual care group. Two patients in the usual care group withdrew consent and were not analysed. In the analysable population, the median age was 66 years (IQR 59 to 76) and 80 (70%) participants were men. In the anakinra group, 21 (36%) of 59 patients had a WHO-CPS score of more than 5 at day 4 versus 21 (38%) of 55 in the usual care group (median posterior absolute risk difference [ARD] -2·5%, 90% credible interval [CrI] -17·1 to 12·0), with a posterior probability of ARD of less than 0 (ie, anakinra better than usual care) of 61·2%. At day 14, 28 (47%; 95% CI 33 to 59) patients in the anakinra group and 28 (51%; 95% CI 36 to 62) in the usual care group needed ventilation or died, with a posterior probability of any efficacy of anakinra (hazard ratio [HR] being less than 1) of 54·5% (median posterior HR 0·97; 90% CrI 0·62 to 1·52). At day 90, 16 (27%) patients in the anakinra group and 15 (27%) in the usual care group had died. Serious adverse events occurred in 27 (46%) patients in the anakinra group and 21 (38%) in the usual care group (p=0·45).Interpretation: Anakinra did not improve outcomes in patients with mild-to-moderate COVID-19 pneumonia. Further studies are needed to assess the efficacy of anakinra in other selected groups of patients with more severe COVID-19.Funding: The Ministry of Health, Programme Hospitalier de Recherche Clinique, Foundation for Medical Research, and AP-HP Foundation.

Abstract: Background Pulmonary arterial hypertension (PAH) is a rare complication of systemic lupus erythematosus (SLE). Methods We identified all patients with SLE and PAH (SLE-PAH) who were enrolled in the French Pulmonary Hypertension Registry with a diagnosis confirmed by right heart catheterization (RHC). A control group of 101 patients with SLE without known PAH was selected from SLE expert centers participating in the Pulmonary Hypertension Registry. Survival was estimated by the Kaplan-Meier method. Hazard ratios associated with potential predictors of death were estimated using Cox proportional hazard models. Results Of the 69 patients with SLE-PAH identified in the French Pulmonary Hypertension Registry, 51 were included in the study. They did not differ from the control group regarding age, sex, or duration of SLE at the time of the analysis but had a higher frequency of anti-SSA and anti-SSB antibodies. The delay between SLE diagnosis and PAH diagnosis was 4.9 years (range, 2.8-12.9) years. The 3- and 5-year overall survival rates were 89.4% (95% CI, 76.2%-96.5%) and 83.9% (95% CI, 68.8%-92.1%), respectively. The survival rate was significantly better in patients with anti-U1-RNP antibodies ( P = .04). Conclusions Patients with SLE-PAH have an overall 5-year survival rate of 83.9% after the PAH diagnosis. Anti-SSA/SSB antibodies may be a risk factor for PAH, and the presence of anti-U1-RNP antibodies appears to be a protective factor regarding survival.

Abstract: Introduction La drepanocytose est la maladie genetique la plus frequente en France avec une incidence moyenne en 2010 de 1/2364 naissances. C’est une maladie multisystemique avec des atteintes polymorphes dont la plus parlante est la crise vaso-occlusive. Plusieurs progres therapeutiques ont vu le jour avec comme principaux traitement l’hydroxyuree, les echanges transfusionnels, l’allogreffe de moelle et actuellement l’avenement de la therapie genique. Tous ces progres ont contribue a diminuer la morbi-mortalite relative a cette affection. Cependant, malgre toutes les avancees therapeutiques realisees, le traitement des ulceres de jambe dans la maladie drepanocytaire reste mal codifie. Cette complication garde un impact majeur sur la vie des patients a cause des douleurs chroniques engendrees, qui mettent des mois voire des annees pour cicatriser, entrainant une degradation de la qualite de vie ainsi qu’une desinsertion socioprofessionnelle. Les ulceres de jambe de la drepanocytose sont associes a un profil plus hemolytique. Celui-ci est associe a une diminution de la biodisponibilite de l’oxyde nitrique (NO) alterant la vaso reactivite, favorisant l’activation endotheliale et le developpement d’une vasculopathie ischemique. Materiels et methodes Nous avons mene une etude retrospective chez les patients drepanocytaires adultes traites dans notre centre entre janvier 2015 et decembre 2017 pour un ulcere de jambe de plus de 1cm2 afin d’evaluer l’efficacite du traitement par trinitrine. Les patients ayant d’autres causes potentielles d’ulcerations (diabete, insuffisance arterielle, maladie systemique, insuffisance veineuse) ont ete exclues. Le suivi photographique etait realise pour tous les patients et analyse a l’aide du logiciel Pictzar lors de chaque pansement, la surface etait estimee par le calcul : longueur par largeur. Les pansements etaient realises une fois par semaine dans notre centre et 1 jour sur 2 au domicile par une infirmiere qui suivait les memes instructions. Une pulverisation de trinitrine a 0,30 mg etait appliquee lors de chaque soin apres avoir retire la fibrine. Notre critere de jugement principal etait la vitesse de cicatrisation (diminution de surface/jours), le critere de jugement secondaire etait la duree de cicatrisation. Un test de Mann Withney etait utilise pour la comparaison des medianes. Resultats Dix-sept patients ayant un syndrome drepanocytaire majeur (SDM) dont 16 drepanocytaires SS et 1 drepanocytaire Sβ0-Thalasemique, ont ete inclus. Six patients SS (2 hommes et 4 femmes) constituaient le groupe ayant recu de la trinitrine (TNT) avec une moyenne d’âge de 47 ans. Dix patients SS (1 femme et 9 hommes) et 1 patient Sβ0-Thalassemique n’ont pas recu de TNT avec une moyenne d’âge de 47 ans. Il n’y avait pas de difference significative (p = 0,3) des tailles medianes des ulceres a l’inclusion (5,75 cm2 vs 2,4 cm2). La mediane des vitesses de cicatrisation dans le groupe TNT etait sensiblement plus rapide que dans le groupe controle, sans atteindre une significativite statistique (0,11 cm2/j vs 0,05 cm2/j, p = 0,08). La duree mediane de cicatrisation etait de 56 jours dans le groupe TNT (mais un patient avait toujours un ulcere actif en fin d’analyse), tandis qu’elle etait de de 100 jours dans le groupe controle. Conclusion Notre etude retrospective, sur un faible effectif de patients, montre une tendance a l’acceleration des vitesses de cicatrisation par l’adjonction de trinitrine lors des soins. Une etude randomisee controlee est necessaire pour confirmer ces premiers resultats. D’autres traitements vasodilatateurs pourraient egalement etre testes suivant une methodologie similaire.

Abstract: Introduction Nous rapportons le cas d’une patiente atteinte de connectivite mixte et qui a developpe a l’âge de 48 ans une insuffisance renale aigue avec microangiopathie thrombotique (MAT) en rapport avec l’association d’une crise renale sclerodermique et d’un purpura thrombotique thrombocytopenique acquis (PTTa). Cette association est tres exceptionnelle, ce qui explique que nous la rapportions. Observation Une patiente nee en 1955, est diagnostiquee a l’âge de 48 ans d’une connectivite mixte (MCTD) evoluant depuis 3 ans, avec un tableau clinique evocateur de sclerodermie systemique qui associe des arthralgies, une pericardite, un phenomene de Raynaud complique d’ulcerations digitales et une sclerodactylie. La capillaroscopie trouve des megacapillaires. La patiente a des Ac anti-nucleaires a 1/8000, des Ac anti-ADN natif double brin a 13 IU/mL (test de FARR) des anti-ECT positifs de type anti-RNP sans autre specificite. En octobre 2003, elle developpe une fievre, des myalgies avec un deficit musculaire proximal et une confusion avec une hemiparesie droite. Biologiquement : une anemie hemolytique avec peu de schizocytes, thrombopenie (78 000/mm3), creatine kinase > 4000 IU/L, creatinine = 118 mmol/L. La biopsie musculaire met en evidence une myopathie inflammatoire, et la patiente recoit trois bolus de methylprednisolone a 15 mg/kg/j relaye par prednisone 1 mg/kg/j. Par ailleurs, le dosage d’ADAMTS-13 est 2,5 g/24 h), une thrombopenie (7000/mm3) et l’apparition d’une hypertension arterielle moderee. La biopsie renale retrouve une proliferation cellulaire myo-intimale des arteres de petit et de moyen calibre qui predomine sur les arteres inter-lobulaires, avec des thromboses intra-luminales. La confirmation histologique de la microangiopathie thrombotique avec des lesions vasculaires de sclerodermie a justifie la reduction de la dose de corticoides et l’introduction d’inhibiteurs de l’enzyme de conversion en plus des echanges plasmatiques et du cyclophosphamide par voie IV, ce qui a permis la recuperation de la fonction renale (creatinine = 123 μmol/L) en novembre 2003. Deux ans plus tard, elle presente une fievre et un abdomen chirurgical associes a une confusion. On note une creatinine = 140 μmol/L avec une thrombopenie severe Discussion Le PTTa et la CRS se caracterisent par une MAT dont la survenue est exceptionnelle au cours de la MCTD. La distinction entre le PTTa et la forme normotensive de la CRS est difficile mais primordiale, car le traitement est radicalement different. Dans notre cas, le diagnostic du PTTa est affirme par l’activite effondree de l’ADAMTS-13 et la presence des anticorps anti-ADAMTS-13. Le premier episode de CRS est confirme par une biopsie renale qui n’a pas ete realisee au cours de la rechute a cause de la thrombopenie. Actuellement, le traitement du PTTa se base plutot sur l’association de la corticotherapie, des echanges plasmatiques et du rituximab. Par ailleurs, une dose de corticotherapie > 15 mg constitue un facteur favorisant la survenue d’une CRS dans le cadre d’une MCTD/sclerodermie, et serait a eviter chez cette patiente. Conclusion Nous rapportons l’association d’une crise renale sclerodermique et d’un PTTa chez une patiente ayant une connectivite mixte. Le traitement associe des corticoides, des immunosuppresseurs et les echanges plasmatiques.

Abstract: Introduction La morphine est couramment utilisee dans la prise en charge hospitaliere de la crise vaso-occlusive (CVO) des patients atteints d’un syndrome drepanocytaire majeur (SDM) [1] . Des cas d’insuffisance corticotrope induite par la morphine ont ete rapportes par plusieurs auteurs, notamment en oncologie [2] ; la morphine serait responsable d’un retrocontrole negatif au niveau hypothalamo-hypophysaire via l’activation de son recepteur μ [3] . L’impact potentiel de la morphine sur l’axe corticotrope au cours de la CVO chez le patient drepanocytaire n’est cependant pas connu. Nous rapportons ici notre experience et la decouverte d’une insuffisance corticotrope chez des patients drepanocytaires hospitalises pour CVO ou syndrome thoracique aigu (STA) et traites par morphine. Patients et methodes Cette etude exploratoire, prospective et monocentrique, a ete menee d’avril a decembre 2016. Ont ete inclus les patients adultes avec un SDM, hospitalises pour CVO ou STA et traites par morphine en intraveineux. Une 1re phase de l’etude a concerne des patients pour lesquels une hypotension (definie par une pression arterielle (PA) systolique Resultats Vingt-sept patients, d’âge median 30 ans (18–43), suivis pour un SDM homozygote SS (25) ou heterozygote composite SC (2), hospitalises pour CVO (22) ou STA (5) ont ete inclus. Aucune exposition cortisonique prealable n’etait rapportee ; 6 patients avaient une hemochromatose post transfusionnelle sous traitement chelateur. Dans le groupe de patients hypotendus ( n = 15 ; mediane PA 92/49 mmHg), 14 patients (93 %) avaient une insuffisance corticotrope (mediane cortisol 50 nmol/L, Q1–Q3 34–90 ; mediane ACTH 4,1 ng/L, Q1–Q3 2,2–7,9). Dans le groupe asymptomatique ( n = 12 ; mediane PA 115/65 mmHg), une insuffisance corticotrope (mediane cortisol 51 nmol/L, Q1–Q3 40–75 ; mediane ACTH 7,3 ng/L, Q1–Q3 4,6–11,3) etait objectivee chez 4 patients (33 %). La consommation mediane de morphine au cours des 24 heures precedant le dosage hormonal etait de 58 mg [30–68] dans le groupe de patients hypotendus et de 35 mg [23–49] dans le groupe asymptomatique. Parmi les patients avec une insuffisance corticotrope ( n = 18), le test de stimulation a l’ACTH, realise a distance de l’hospitalisation chez seulement 5 patients, etait normal et permettait l’arret de la supplementation en hydrocortisone ; l’IRM hypophysaire, realisee chez 4 patients, etait sans anomalie decrite. Conclusion Dans cette etude preliminaire, nous avons objective une insuffisance corticotrope chez un nombre important de patients drepanocytaires traites par morphine lors d’une CVO ou d’un STA, et ce meme chez des patients sans signe clinique apparent d’insuffisance corticotrope. Ces donnees devront etre confirmees et precisees au travers d’une etude prospective cas/temoin portant sur un grand nombre de patients et l’impact d’un traitement substitutif par hydrocortisone sur l’evolution (duree, intensite) de la CVO devra etre evalue.

Abstract: Objective To investigate the clinical characteristics, outcomes, and results of hepatitis C virus (HCV) RNA analyses in a group of patients with HCV-associated mixed cryoglobulinemia (MC) vasculitis who experienced a relapse of vasculitis despite achieving a sustained viral response to treatment with antiviral agents. Methods HCV RNA testing was performed by the transcription-mediated amplification (TMA) method in sera and cryoprecipitates (detection limit 2.5 IU/ml). HCV replication was assessed in peripheral blood mononuclear cells (PBMCs) by a modified real-time polymerase chain reaction assay (detection limit 15 IU/106 cells). Results We identified 8 patients with relapse of HCV-MC vasculitis despite their having achieved a sustained viral response to treatment. Relapse appeared early after the end of treatment (mean ± SD 2.5 ± 3.5 months) and included mainly purpura (n = 7) and arthralgia (n = 5). Relapse was associated with an increase in serum cryoglobulin levels as compared with end-of-treatment levels (mean ± SD 0.3 ± 0.09 gm/liter and 0.08 ± 0.04 gm/liter, respectively; P < 0.01) and a decrease in C4 levels. In most patients, the relapse was brief, and the MC vasculitis manifestations subsided. A search for HCV RNA by TMA was negative in all patients tested (7 of 8 patients), both in sera and in cryoprecipitates. HCV replication was not found in PBMCs from any of the patients tested (6 of 8 patients). In 3 patients, the MC vasculitis symptoms persisted and were associated with elevated cryoglobulin levels. B cell lymphoma was diagnosed in 2 of these 3 patients. Conclusion Relapse of MC vasculitis does occur in a few patients with HCV infection, despite achieving a sustained viral response, and this relapse is not related to persistence of virus. Relapse is short-lived and may be induced by the withdrawal of interferon alfa therapy. However, in patients with persistent MC vasculitis symptoms, a different underlying condition should be considered, especially B cell lymphoma.

Abstract: Objective: To develop and assess the reliability and construct validity of a scale assessing disability involving the mouth in systemic sclerosis (SSc). Methods: We generated a 34-item provisional scale from mailed responses of patients (n = 74), expert consensus (n = 10) and literature analysis. A total of 71 other SSc patients were recruited. The test–retest reliability was assessed using the intraclass coefficient correlation and divergent validity using the Spearman correlation coefficient. Factor analysis followed by varimax rotation was performed to assess the factorial structure of the scale. Results: The item reduction process retained 12 items with 5 levels of answers (total score range 0–48). The mean total score of the scale was 20.3 (SD 9.7). The test–retest reliability was 0.96. Divergent validity was confirmed for global disability (Health Assessment Questionnaire (HAQ), r = 0.33), hand function (Cochin Hand Function Scale, r = 0.37), inter-incisor distance (r = −0.34), handicap (McMaster-Toronto Arthritis questionnaire (MACTAR), r = 0.24), depression (Hospital Anxiety and Depression (HAD); HADd, r = 0.26) and anxiety (HADa, r = 0.17). Factor analysis extracted 3 factors with eigenvalues of 4.26, 1.76 and 1.47, explaining 63% of the variance. These 3 factors could be clinically characterised. The first factor (5 items) represents handicap induced by the reduction in mouth opening, the second (5 items) handicap induced by sicca syndrome and the third (2 items) aesthetic concerns. Conclusion: We propose a new scale, the Mouth Handicap in Systemic Sclerosis (MHISS) scale, which has excellent reliability and good construct validity, and assesses specifically disability involving the mouth in patients with SSc.

Abstract: Pulmonary arterial hypertension (PAH) refers to a spectrum of diseases characterised by a permanent increase in pulmonary vascular resistance leading to right ventricular dysfunction and, ultimately, death [1]. PAH can be idiopathic, familial or associated with a number of conditions or diseases, such as congenital heart disease, portal hypertension, HIV infection, and exposure to toxins and drugs, including appetite suppressants. PAH may also develop in the context of connective tissue disease (CTD), and may complicate the course of systemic sclerosis (SSc), systemic lupus erythematosus (SLE), and mixed connective tissue disease (MCTD) [2, 3]. Over the past decade, significant advances in the better understanding of PAH pathophysiology have led to the development of “specific” therapies that target aberrant molecular signalling pathways. Although these treatments favourably impact clinical status, long-term survival remains poor for patients with PAH, particularly for those with CTD [2, 4]. In the current issue of the European Respiratory Review , Johnson and Granton [5] give an overview of the epidemiology, prognostic factors and survival of SSc- and SLE-associated PAH. In this review, important differences between these two forms of PAH are highlighted. SSc is …

Abstract: International audience; The SARS-CoV-2 Omicron variant can escape neutralization by vaccine-elicited and convalescent antibodies. Memory B cells (MBCs) represent another layer of protection against SARS-CoV-2, as they persist after infection and vaccination and improve their affinity. Whether MBCs elicited by mRNA vaccines can recognize the Omicron variant remains unclear. We assessed the affinity and neutralization potency against the Omicron variant of several hundred naturally expressed MBC-derived monoclonal IgG antibodies from vaccinated COVID-19-recovered and -naive individuals. Compared with other variants of concern, Omicron evaded recognition by a larger proportion of MBC-derived antibodies, with only 30% retaining high affinity against the Omicron RBD, and the reduction in neutralization potency was even more pronounced. Nonetheless, neutralizing MBC clones could be found in all the analyzed individuals. Therefore, despite the strong immune escape potential of the Omicron variant, these results suggest that the MBC repertoire generated by mRNA vaccines still provides some protection against the Omicron variant in vaccinated individuals.

Abstract: In addition to serum immunoglobulins, memory B cell (MBC) generation against SARS-CoV-2 represents another layer of immune protection, but the quality of MBC responses in naive and COVID-19-recovered individuals after vaccination remains ill-defined. We studied longitudinal cohorts of naive individuals and disease-recovered patients for up to 2 months after SARS-CoV-2 mRNA vaccination. We assessed the quality of the memory response by analysis of VDJ repertoires, affinity and neutralization against variants of concern (VOCs), using unbiased cultures of 2452 MBCs. Upon boosting, the MBC pool of recovered patients selectively expanded, further matured and harbored potent neutralizers against VOCs. Although naïve individuals had weaker neutralizing serum responses, half of their RBD-specific MBCs displayed high affinity towards multiple VOCs, including delta (B.1.617.2), and one-third retained neutralizing potency against beta (B.1.351). Our data suggest that an additional challenge in naive vaccinees could recall such affinity-matured MBCs and allow them to respond efficiently to VOCs., Graphical Abstract, To better understand B cell responses to SARS-CoV-2 mRNA vaccination, Sokal et al. analyzed memory B cells from COVID-19-recovered and -naive individuals. In recovered patients, vaccination amplifies a broad repertoire of matured MBCs and generates variant-neutralizing plasma cells. In naïve individuals, vaccination induces an MBC pool containing potent neutralizing clones against all current variants of concern, including beta and delta.
