A new autoinflammatory syndrome related to somatic mutations of UBA1 was recently described and called VEXAS syndrome ('Vacuoles, E1 Enzyme, X-linked, Autoinflammatory, Somatic syndrome').To describe clinical characteristics, laboratory findings and outcomes of VEXAS syndrome.One hundred and sixteen patients with VEXAS syndrome were referred to a French multicentre registry between November 2020 and May 2021. The frequency and median of parameters and vital status, from diagnosis to the end of the follow-up, were recorded.The main clinical features of VEXAS syndrome were found to be skin lesions (83%), noninfectious fever (64%), weight loss (62%), lung involvement (50%), ocular symptoms (39%), relapsing chondritis (36%), venous thrombosis (35%), lymph nodes (34%) and arthralgia (27%). Haematological disease was present in 58 cases (50%): myelodysplastic syndrome (MDS; n = 58) and monoclonal gammopathy of unknown significance (n = 12; all patients with MGUS also have a MDS). UBA1 mutations included p.M41T (45%), p.M41V (30%), p.M41L (18%) and splice mutations (7%). After a median follow-up of 3 years, 18 patients died (15·5%; nine of infection and three due to MDS progression). Unsupervised analysis identified three clusters: cluster 1 (47%; mild-to-moderate disease); cluster 2 (16%; underlying MDS and higher mortality rates); and cluster 3 (37%; constitutional manifestations, higher C-reactive protein levels and less frequent chondritis). The 5-year probability of survival was 84·2% in cluster 1, 50·5% in cluster 2 and 89·6% in cluster 3. The UBA1 p.Met41Leu mutation was associated with a better prognosis.VEXAS syndrome has a large spectrum of organ manifestations and shows different clinical and prognostic profiles. It also raises a potential impact of the identified UBA1 mutation.

Acute Parvovirus B19 (PVB19) infection is responsible for erythema infectiosum in children and non-specific polyarthralgias in immunocompetent adults associated with skin lesions and rarer manifestations (hepatic, neurological, cardiac or nephrological). In immunocompromised patients, cytopenias are more frequent and in some cases, viremia persists and is responsible for PVB19 chronic infection. PVB19 is responsible for pure red cell aplasia during chronic hemolytic diseases. Acute PVB19 infection is a differential diagnosis of some autoimmune diseases and has been suspected to be a trigger for some autoimmune diseases because of its ability to promote the emergence of autoimmune markers. Mechanisms of molecular mimicry, induction of apoptosis and activation of enzymes have been demonstrated, explaining in part the production of autoantibodies during infection. However, the demonstration of a causal relationship in the triggering of autoimmune disease remains to be done. This review provides a synthesis of the PVB19 infection clinical data in adults with a particular focus on these links with autoimmunity.

Resumen La enfermedad de Still del adulto es una enfermedad autoinflamatoria poligenica cuya etiologia sigue siendo desconocida. La naturaleza autoinflamatoria la distingue de las enfermedades autoinmunitarias por autoanticuerpos. Desde el punto de vista clinico, es una triada clasica que combina fiebre hectica, erupcion evanescente y artritis. Aunque es benigna en la gran mayoria de los casos, pueden producirse complicaciones que ponen en peligro la vida. Por definicion, la enfermedad afecta a personas de mas de 16 anos, pero la mayoria de los expertos esta de acuerdo en que la forma adulta y la forma pediatrica pertenecen a un continuo patologico: la enfermedad de Still. En ausencia de un biomarcador especifico, el diagnostico sigue basandose en criterios clinicos y de laboratorio, previa exclusion de los diagnosticos diferenciales. Las principales afecciones que deben descartarse son las infecciones virales, en particular herpeticas, y las hemopatias malignas. En el plano terapeutico, existe un consenso para el tratamiento precoz, en particular el uso de bioterapias, en caso de una respuesta inadecuada a la corticoterapia. Las bioterapias dirigidas a la interleucina 1 y la interleucina 6 ocupan entonces un lugar prominente en la estrategia terapeutica.

Adult-onset Still's disease (AOSD) is a rare multisystemic disorder and a diagnostic challenge for physicians because of the wide range of differential diagnoses. Common features of AOSD and secondary hemophagocytic lymphohistiocytosis (sHLH) could favour diagnostic uncertainty, in particular in case of infection-related sHLH.A 61-year-old man was admitted to our internal medicine department for suspected AOSD. He reported a 2-week history of sudden onset fever, headaches, myalgia, sore throat, diarrhoea, and an erythematous macular rash of the trunk as well as petechial purpuric lesions on both legs on return from Reunion Island. Laboratory tests found cytopenia, hepatic cytolysis, hypertriglyceridaemia, and hyperferritinaemia. Hemophagocytosis was diagnosed on bone marrow aspiration in favour of the diagnosis of secondary hemophagocytic lymphohistiocytosis (sHLH). Subcutaneous anakinra (100mg) was initiated to treat sHLH with favourable course. Oral doxycycline was added 3days later because of atypical features for AOSD diagnosis such as diarrhoea, hypergammaglobulinaemia, and doubtful serologies for Rickettsia and Coxiella. Three weeks later, Rickettsia typhi serology was checked again and revealed an increase in IgG titer4 times that confirmed the diagnosis of murine typhus. A diagnosis of murine typhus complicated by sHLH was retained, successfully treated by anakinra and doxycycline.Our observation shows that AOSD diagnosis has to be stringent due to the many differential diagnoses, particularly infection complicated by sHLH, which may be rare. It is important to consider murine typhus in patients returning from endemic areas, such as La Reunion or other tropical areas, when they present fever of unknown origin with non-specific clinical features. Moreover, this case illustrates the effectiveness of IL-1 blockers as a treatment for symptomatic sHLH without severity criteria, regardless of the aetiology.

To assess the relevance of lumbar puncture (LP) for the etiological diagnosis of uveitis and to establish predictive factors associated with its contributory use.We performed a retrospective study of patients with de novo uveitis who were referred to our tertiary hospital for etiological diagnosis of uveitis, between January 2003 and July 2018. We included patients who underwent a LP as part of the etiological assessment of uveitis. LP was considered as contributory if it led to the etiological diagnosis or to correct the initially suspected diagnosis.One hundred eighty eight of the 1211 patients referred for evaluation (16%) had an LP, among these patients, 93 (49.4%) had abnormal results including 69 (36.7%) patients with hypercellularity, 69 (36.7%) with hyperproteinorachia, and 28 (14.9%) with oligoclonal bands and/or increased IgG index. LP was considered as contributing to the diagnosis in only 31 (16.4%) cases, among which there were 10 (5.3%) contributions to the etiological diagnosis and 21 (11.2%) modifications in the diagnosis classification. Multivariate analysis established that African ethnicity (p0.001), bilateral uveitis (p = 0.01), presence of macular edema or retinal serous detachment (p = 0.048), presence of retinal vasculitis (p0.001), presence of neurological signs or symptoms (p = 0.01), and contributing cerebral MRI (p0.001) were all significantly associated with a contributory LP. LP did not lead to any therapeutic modification.LP direct contribution to the diagnosis was rare and most often detected non-specific abnormalities. LP should be performed only in cases of neurological clinical signs or symptoms, suspicion of multiple sclerosis, Vogt-Koyanagi-Harada, or syphilis.

Sarcoidosis can develop into a chronic disease in about 30% of cases. When general treatment is indicated, corticosteroids are the first-line treatment. More than one third of patients treated with corticosteroids receive a steroid-sparing agent. Although methotrexate is the most commonly used sparing agent, synthetic antimalarials have been used for more than fifty years on the basis of small, randomised, therapeutic trials. Despite this low level of evidence, chloroquine or more often hydroxychloroquine are used in daily practice, particularly to treat skin, bone and joint sarcoidosis, as well as hypercalcemia and certain types of uveitis. This review summarises the state of knowledge on steroid-sparing therapy in sarcoidosis, particularly in its extra-pulmonary form. These data support the need for good quality therapeutic trials to validate the use of hydroxychloroquine in this specific indication.

Spontaneous adrenal hemorrhages (AH) are a rare condition with no consensus about their management.Patients were identified using the Medicalization of the Information System Program database, imaging software and a call for observations to internists, intensivists and obsetricians working at our institution. Adult patients whose medical records were complete and whose diagnosis was confirmed by medical imaging were included.From 2000 to 2007, 20 patients were identified, including 15 were women. The clinical onset of AH was non-specific. In five cases, AH occurred during pregnancy; four of them were unilateral and right sided. The etiology of the other fifteen (bilateral adrenal hemorrhage in 11) were as follows: antiphospholipid syndrome (n=8), heparin-induced thrombocytopenia (n=4), essential thrombocythemia (n=3), spontaneous AH due to oral anticoagulants (n=1), complication of a surgical act (n=3), and sepsis (n=3). In seven cases, two causes were concomitant. The diagnosis of AH was often confirmed by abdominal CT. An anticoagulant treatment was initiated in 16 cases. Ten of the eleven patients presenting with bilateral adrenal hematomas were treated using a long-term substitute opotherapy. One patient died because of a catastrophic antiphospholipid syndrome.The clinical onset of HS is heterogeneous and non-specific. The confirmatory diagnosis is often based on abdominal CT. The search for an underlying acquired thrombophilia is essential and we found in this study etiological data comparable to the main series in the literature. Adrenal insufficiency is most of the time definitive in cases of bilateral involvement.

Introduction Le syndrome inflammatoire prolonge inexplique (SII) est defini par analogie avec la fievre prolongee inexpliquee, par : un syndrome inflammatoire (CRP ≥ a 30 mg/L et/ou elevation de la vitesse de sedimentation selon la formule de Miller), evoluant ≥ 3 semaines associe a une temperature corporelle ≤ 38,3 °C, sans etiologie identifiee au terme de 3 jours d’hospitalisation ou 3 consultations [1] . Contrairement aux fievres prolongees inexpliquees, peu d’etudes se sont interessees aux SIIs [2] , [3] . Nous avons realise une etude afin de definir le spectre etiologique, la rentabilite des examens complementaires et le pronostic des SIIs. Patients et methodes Nous avons conduit une etude retrospective de 2005 a 2020 dans un centre universitaire. Le diagnostic de SII reposait sur les criteres de Vanderschueren [1] . Les observations ont ete identifiees a partir de l’outil informatique Easily Recherche, en utilisant les mots cles : « syndrome inflammatoire prolonge », « syndrome inflammatoire inexplique », « syndrome inflammatoire » ET « prolonge » ET « inexplique », et en interrogeant les medecins de trois services de medecine interne. Le diagnostic positif des maladies systemiques (arterite a cellules geantes (ACG), vascularites a anticorps anti-cytoplasme des polynucleaires neutrophiles (ANCA) …) reposait sur les criteres actualises et consensuels de classification. Seuls les examens complementaires, qui ont concouru au diagnostic etiologique, ont ete consideres comme contributifs. L’efficacite et la tolerance des traitements d’epreuve (antibiotherapie, colchicine, corticoides, immunosuppresseurs) ont ete analysees. La guerison a ete definie par l’absence de symptome et une proteine C-reactive Resultats 18 hommes et 39 femmes (âge moyen : 67 ans, extremes : 29-100 ans) ont ete inclus. Apres un suivi median de 48 mois, un diagnostic etait retenu chez 26/57 patients (46 %). Il s’agissait de : (1) 13 maladies inflammatoires non infectieuses (7 ACG, 3 polyangeites microscopiques (PAM), une maladie de Takayasu, une sarcoidose, et une maladie de Still), avec un delai diagnostique moyen de 67 jours 2) 10 neoplasies (8 hemopathies malignes : 3 lymphomes, 2 myelodysplasies incluant un patient qui presentait un phenotype compatible avec un VEXAS, une leucemie aigue myeloblastique cryptoleucemique, un thymome, une maladie de Castleman ; et 2 tumeurs solides), avec un delai diagnostique moyen de 20 jours 4) et une cause autre : un syndrome de Sweet (688 jours). Un 18FDG-PET a ete realise chez 42 patients (72 %) et a ete contributif dans 12 cas (29 %). Cinq patients ayant un 18FDG-PET contributif presentaient des anomalies au scanner initial, qui ont ete considerees a posteriori comme contributives. La recherche d’ANCA et les serologies ont ete contributives dans 3 cas de PAM et un cas de fievre Q aigue, respectivement. L’echographie trans-thoracique (30 patients) n’a jamais ete contributive mais l’echographie transoesophagienne a ete contributive dans un cas. Parmi les 23 biopsies d’artere temporale realisees systematiquement, 5 (22 %) ont ete contributives. Le myelogramme, realise chez un tiers des patients, a ete contributif dans 3 cas d’hemopathies. Les biopsies ganglionnaires, musculaires et cutanees, orientees par le 18FDG-PET, ont ete contributives dans 6 cas (5 hemopathies et une sarcoidose), un cas (tumeur solide) et un cas (syndrome de Sweet profond), respectivement. Les endoscopies (gastroscopie : 61 % des patients ; coloscopie : 53 % ; fibroscopie bronchique : 28 %) et la biologie moleculaire (28 %) n’ont jamais ete contributives. Au terme du suivi, 8 des 31 patients sans diagnostic etaient consideres au terme du suivi comme gueris : 3 spontanement et 5 apres un traitement d’epreuve (2 patients sous corticosteroides et antibiotherapie, 2 patients sous antibiotherapie seule et un patient sous corticosteroides seuls). Cinq patients (16 %) sans diagnostic etaient decedes : un deces etait lie au traitement d’epreuve. Les autres causes de deces etaient : une infection pulmonaire, une decompensation cardiaque, et deux causes inconnues. Le SII a persiste chez 18 patients sans diagnostic final, dont 10 avaient recu un traitement d’epreuve. Conclusion Plus de la moitie des SII demeure d’etiologie indeterminee. Les maladies inflammatoires non infectieuses et les hemopathies rendent compte de la majorite des causes identifiees. Le 18FDG-PET a ete contributif au diagnostic dans 29 % des cas. La majorite des SII sans diagnostic identifie persiste. La mortalite est elevee dans ce groupe de patients. La place et la nature des traitements d’epreuve reste a definir.

Introduction La sarcoidose est une granulomatose systemique d’etiologie indeterminee [1] . De nombreux cas et des series d’infections opportunistes (IO) chez des patients atteints de sarcoidose sont rapportes dans la litterature medicale [2] , [3] . Sont generalement exclues les aspergilloses cavitaires et les tuberculoses, associees respectivement a la fibrose et a des elements demographiques communs. Les agents opportunistes rapportes sont varies (Cryptococcus neoformans, JC virus, mycobacteries atypiques, Nocardia spp.) mais actuellement aucun facteur de risque d’infection opportuniste n’est decrit au cours de la sarcoidose. Patients et methodes Nous avons effectue un recueil de la litterature medicale via le moteur de recherche Medline et realise un appel a observations via le groupe sarcoidose francophone a la recherche d’associations « infection opportuniste » et « sarcoidose ». Les caracteristiques cliniques des IO ont ete comparees a une population temoin constituee de patients porteurs d’une sarcoidose sans IO issus d’une cohorte de notre service. Resultats La revue de la litterature a permis de recenser 164 cas d’infections qualifiees d’opportunistes chez des patients porteurs d’une sarcoidose. Parmi ces 164 infections, 83 etaient des cryptococcoses (51 %) et 39 etaient des leuco-encephalopathies multifocales progressives (LEMP) (24 %). Notre appel a observations a permis de recenser 50 IO chez 49 patients, incluant : 24 cryptococcoses (49 %), 12 LEMP (24 %), 7 pneumocystoses (14 %) et 7 autres infections (14 %) dont 3 mycobacterioses atypiques, 2 nocardioses et 2 infections a cytomegalovirus. Ces 49 patients avec IO ont ete compares a 135 controles porteurs d’une sarcoidose sans IO. Dans le groupe infection opportuniste, le compte lymphocytaire moyen etait de 1000/mm3 (100-2680/mm3) et 14 patients ne presentaient pas de lymphopenie (29 %). Les facteurs de risques identifies en analyse univariee etaient : le sexe masculin (OR = 4,76; IC95 % [2,12 ; 10,00]), la presence d’adenopathies peripheriques (OR = 3,45 ; [1,49 ; 8,04]), d’une hepatomegalie (OR = 8,10 ; [1,91 ; 40,41]) ou d’une splenomegalie (OR = 9,00, [1,80 ; 58,86]), la presence d’une atteinte pulmonaire de stade ≥2 (OR = 6,66 ; [2,80 ; 17,74]), d’une atteinte neurologique centrale (OR = 8,73 ; [1,98 ; 53,52]) ou d’une insuffisance renale (OR = 5,65 ; [1,33 ; 25,24]), la corticotherapie (OR = 10,26 ; [4,15 ; 29,22]) et l’utilisation du cyclophosphamide (OR = 9,42 ; [1,61 ; 98,92]) ou d’un anti-TNFα (OR = 7,68 ; [1,21 ; 83,62]). En analyse multivariee (ajustement sur l’âge et le sexe), les facteurs de risque identifies etaient l’utilisation de corticoides (OR = 10,60 ; [4,31 ; 29,57]) ou d’un anti-TNFα (OR = 13,47 ; [2,05 ; 129,43]), la presence d’une hepatomegalie (OR = 9,91 ; [2,23 ; 55,85]), une atteinte pulmonaire de stade 2 ou superieur (OR = 5,65 ; [2,34 ; 15,36]) et l’insuffisance renale (OR = 11,76 ; [2,32 ; 68,35]). La lymphopenie Conclusion Les facteurs de risque d’IO dans notre etude sont associes a la gravite de la sarcoidose et/ou a sa diffusion systemique. Il existe un facteur confondant lie a l’utilisation des immunosuppresseurs chez des patients avec une sarcoidose plus severe. Dans notre serie, 6 % des patients ont developpe une infection opportuniste sans aucun facteur de risque, suggerant neanmoins une immunosuppression propre a la sarcoidose dans ces cas.

Introduction La maladie de Kawasaki de l’adulte (MKA) est une forme rare de vascularite dont la gravite est liee a l’atteinte coronaire. Nous decrivons dans cette etude les consequences cardio-vasculaires a long terme de la MKA. Patients et methodes Les donnees de suivi cardio-vasculaires des patients de l’Observatoire Francais de la MKA ont ete collectees retrospectivement. Resultats 26 patients ont ete inclus avec un âge median au diagnostic de 30 ans. Au diagnostic, 8 patients presentaient des symptomes cardio-vasculaires : douleur thoracique (5/8), insuffisance cardiaque droite (3/8) ou gauche (2/8) et 5 patients avaient une elevation de la troponine sanguine. Douze patients avaient une atteinte cardiovasculaire au diagnostic : 8 pericardites, 6 arterites coronaires stenosantes, 5 myocardites, 3 anevrysmes coronariens. Treize patients presentaient au moins un facteur de risque cardio-vasculaire, le plus frequent etant le tabagisme (12/13). Dix-sept patients ont recus des immunoglobulines intraveineuses au diagnostic et 19 un traitement anti-inflammatoire. La duree mediane de suivi etait de 60 mois (10 a 192). Deux patients ont presente un evenement cardiovasculaire relie a la MKA durant le suivi : deux infarctus du myocarde, survenus respectivement chez un patient non traite au diagnostic et un patient avec sequelles coronaires connues de sa MKA. Aucun deces n’est survenu. La derniere echocardiographie de suivi (disponible pour 23 patients) retrouvait une fraction d’ejection ventriculaire gauche normale. Un seul des 4 patients ayant beneficie de test fonctionnel de depistage de l’ischemie myocardique a presente un resultat anormal. Deux patients ont beneficie d’une coronarographie durant le suivi dont une seule etait anormale. Neuf patients beneficient encore d’un traitement par antiagregant plaquettaire. Conclusion Cette etude apporte les premieres donnees de suivi cardiovasculaires dans la MKA. Un diagnostic et un traitement precoces semblent importants pour prevenir les complications a long terme, de meme qu’un depistage et une prise en charge systematique des facteurs de risque cardio-vasculaires.

Introduction Au cours de la sarcoidose, une uveite est rencontree chez 25 a 50 % des patients [1] . Peu d’etudes ont evalue l’efficacite des traitements d’epargne cortisonique dans l’uveite sarcoidosique. L’efficacite de l’hydroxychloroquine (HCQ) a ete evaluee et rapportee dans de nombreuses atteintes de la sarcoidose (cutanee, pulmonaire, articulaire, hypercalcemie), mais pas au cours des uveites. Patients et methodes Nous avons mene une etude retrospective afin d’evaluer l’efficacite et la tolerance de l’HCQ chez des patients atteints d’uveite sarcoidosique. Nous avons identifie tous les patients avec un diagnostic d’uveite sarcoidosique traites par HCQ dans notre CHU entre 2003 et 2019. Le diagnostic d’uveite sarcoidosique etait retenu comme prouve, probable ou presume selon les criteres d’Abad modifies [2] . Les patients etaient inclus s’ils etaient traites par HCQ pour une duree minimale de 6 mois, et ne devaient pas recevoir d’autre traitement d’epargne cortisonique a l’introduction de l’HCQ. La presentation ophtalmologique, la duree du traitement, son efficacite et les donnees de tolerance ont ete relevees. Resultats Parmi 294 patients presentant une uveite sarcoidosique, 29 ont ete traites par HCQ. Deux patients ont ete exclus en raison de l’utilisation concomitante d’un autre traitement a visee d’epargne cortisonique. Au total, 27 patients ont ete analyses : 17 uveites sarcoidosiques prouvees, cinq presumees et cinq probables. L’âge moyen etait de 61,1 ans (35-83), avec un sexe ratio femme/homme a 1,45. La distribution anatomique etait : dix panuveites, trois uveites posterieures, neuf uveites anterieures et intermediaires, deux uveites intermediaires, et trois uveites anterieures. 21 uveites etaient compliquees d’œdeme maculaire, douze de cataracte, et sept de glaucome secondaire. A l’initiation de l’HCQ, treize patients recevaient une corticotherapie orale a la dose moyenne de 20 mg/j, et les 14 autres presentaient une cortico-dependance topique. La duree moyenne du traitement etait de 23,3 (± 12,4) mois. Quatorze patients ont presente une rechute inflammatoire sous HCQ, avec un taux de rechutes qui diminuait de 207,6 avant l’introduction du traitement a 56,2 pour 100 patients-annees (p = 0,001). Quinze patients etaient toujours traites par HCQ a la fin du suivi. Parmi eux, quatre patients etaient egalement traites par corticotherapie systemique, avec une dose moyenne de ≤ 5 mg/j (2-5). Un seul patient recevait un traitement local, pour une poussee d’uveite anterieure. L’HCQ a ete arretee chez douze patients au cours du suivi, dont six pour inefficacite jugee par les cliniciens. Quatre patients ont presente des effets indesirables sous HCQ avec des troubles digestifs non severes chez deux patients, une hyperpigmentation induite, et la survenue d’une maculopathie attribuee a l’HCQ chez un patient. Ces effets indesirables ont ete a l’origine de l’arret de l’HCQ chez trois de ces patients. L’HCQ a ete arretee chez deux patients du fait d’une maculopathie severe liee a l’uveite empechant la surveillance maculaire sous HCQ. Un patient a egalement decide d’arreter l’HCQ sans justification. Sur l’ensemble des patients, la dose mediane de prednisone a diminue a 5 mg/j (2-30) (p = 0,02). Conclusion L’HCQ est une option interessante dans l’uveite associee a la sarcoidose en raison de son effet d’epargne cortisonique. Les donnees de tolerance sont rassurantes, avec notamment une surveillance maculaire possible pour la grande majorite des patients. Une etude prospective est necessaire pour confirmer ces resultats.

Introduction La tuberculose est une cause rare d’uveite dans les pays en zone de faible endemie tuberculeuse avec une prevalence estimee entre 3,3 et 7,5 % dans les principales series europeennes recemment rapportees dans la litterature [1] . Materiels et methodes Nous avons realise une etude retrospective incluant les patients pour lesquels un test QuantiFERON avait ete prescrit, au sein d’une cohorte de patients referes en centre tertiaire pour un diagnostic d’uveite, entre janvier 2003 et decembre 2019. Le seuil de positivite du QuantiFERON etait de 0,35 UI/mL. Le diagnostic d’uveite etait etabli selon les criteres de la COTS [2] comprenant 4 criteres: signes cliniques compatibles avec une uveite tuberculeuse; l’exclusion d’uveites d’autres etiologies; la mise en evidence de la mycobacterie ou de son genome; un QuantiFERON positif ou une IDR positive ou la preuve d’une tuberculose guerie ou active sur la radiographie pulmonaire. Les patients etaient presumes atteints d’uveite tuberculeuse s’ils repondaient aux criteres 1 et 2 et a au moins un des criteres 3 et 4. Ont ete collectees les caracteristiques demographiques, cliniques et ophtalmologiques et la reponse au traitement anti tuberculeux. Nous avons calcule les differentes Sensibilites (Se), specificites (Sp), valeurs predictives positives (VPP) et valeurs predictives negatives (VPN) en fonction du seuil du QuantiFERON, avec construction d’une courbe ROC. Les facteurs de reponse a un traitement anti tuberculeux ont ete identifies avec le calcul des odds ratio (OR) et OR ajustes (ORa). Resultats Parmi les 1075 patients adresses pour uveites, 178 (16,5 %) avaient un QuantiFERON positif dont 105 (59 %) avaient un taux superieur a 2 UI/ml. Un test QuantiFERON positif prescrit devant une inflammation oculaire conduit a l’initiation d’un traitement anti tuberculeux chez 5,7 % (62/1075). Selon la COTS, 62 parmi ces 178 patients (34,8 %) ont eu un diagnostic d’uveite tuberculeuse et ont recu une quadritherapie standard pendant six mois. 70,9 % patients (44/62) etaient repondeurs au traitement anti tuberculeux. En analyse univariee un QuantiFERON avec une valeur superieure a 2 UI/mL constitue un facteur predictif de reponse au traitement anti tuberculeux avec un OR a 31, 66 (95 % IC 7,00–143,24; p Discussion Dans notre serie, nous avons observe une mediane du test QuantiFERON plus elevee dans le groupe uveites tuberculeuses que dans le groupe uveites non-repondeuses au traitement anti tuberculeux avec une meilleure reponse au traitement anti tuberculeux lorsque le test QuantiFERON etait superieur a 2 UI/mL. Cette approche est interessante et peut etre utilisee pour aider le clinicien a instaurer ou non un traitement anti tuberculeux et en predire la reponse. Dans l’etude de Gineys et al. de 2011, la reponse au traitement anti tuberculeux etait egalement meilleure avec 15 succes contre 10 echecs avec le test QuantiFERON a 7,67 contre 1,22 respectivement (p = 0,026) [3] . Conclusion Nous rapportons ici la serie la plus importante d’utilisation du test Quantiferon pour le diagnostic etiologique des uveites. Alors qu’une proportion importante (1/6e) de patients referes pour une uveite presente un test QuantiFERON positif, celui-ci n’entraine la prescription d’un traitement specifique que dans 1/3 des cas positifs. Toutefois, lorsqu’il est initie, ce traitement est efficace dans la grande majorite des cas. Un seuil de 2 UI/mL est associe a une meilleure reponse au traitement anti tuberculeux.

In the past ten years, the better understanding of the pathophysiological mechanisms underlying inflammatory and autoimmune diseases has led to the emergence of many targeted therapies. Among them, the Janus kinase inhibitors are acting upstream in the inflammatory cascade of several key cytokines in disorders such as rheumatoid arthritis, ulcerative colitis or psoriasis. At the moment, these three diseases represent the only indications validated by the FDA and the EMA of the use of JAK inhibitors apart from hematology. Preclinical data and therapeutic trials indicate their efficacy in other autoimmune or inflammatory conditions, such as lupus, dermatomyositis, ankylosing spondylitis, sarcoidosis and giant cell arteritis. This review provides a summary of current use and advancement of knowledge in the use of JAK inhibitors in pathologies faced by internists.

Objectives The objective of this report is to investigate the feasibility of collecting patient-reported outcomes (PROs) via e-questionnaires delivered to patients with chronic inflammatory diseases (CIDs). Methods Consecutive outpatients with a confirmed diagnosis of systemic lupus erythematosus, primary Sjögren’s syndrome or inflammatory bowel disease were followed at two medical departments. Patients received monthly e-mails containing the SF36, Hospital Anxiety and Depression scale and an analogue symptom scale over a six-month period. Participation rate, socio-demographic characteristics and patients’ satisfaction were analysed. Results A total of 128 patients were included (79% female; mean age: 42 ± 12 years). Eighty-two per cent of questionnaires were returned. The monthly participation rate ranged from 89% to 77%, with a six-month attrition rate of 13%. The mean completion rate of questionnaires was 98%. Factors significantly associated with increased answer rate were: married/couple status, greater number of children at home and previous participation in online surveys. The main reasons for non-response were: ‘too busy to participate’ (35%) and ‘away from home Internet access’ (31%). Overall, 68% of the participants found the study convenient and 96% agreed to continue at a monthly or bimonthly frequency. Conclusion Online home self-assessment of PROs was feasible in the setting of CIDs. Patients were satisfied and willing to continue the survey. The Internet allows immediate and sophisticated presentation of PROs to clinicians. Future studies are warranted to determine how PRO monitoring may contribute to routine care in CIDs and other diseases.

Sarcoidosis is one of the leading causes of inflammatory eye disease. Any part of the eye and its adnexal tissues can be involved. Uveitis and optic neuropathy are the main manifestations, which the internists face. This review reports the state of knowledge for these two ocular involvements and proposes an assessment-algorithm for sarcoidosis in patients with suspected sarcoid uveitis. Two groups of patients with sarcoid uveitis can be distinguished: one young and multiethnic group in which ophthalmological findings are various and another group of elderly Caucasian women with mostly chronic posterior uveitis. Clinically isolated uveitis revealing sarcoidosis remains a strictly ocular condition in a large majority of cases. Although it could be a serious condition involving functional prognosis, an early recognition in addition to a growing therapeutic arsenal including intravitreal implant seems to have improved visual prognosis of the disease in the last years. Systemic corticosteroids are indicated when uveitis does not respond to topical corticosteroids or when there is bilateral posterior involvement, especially macular edema and occlusive vasculitis. In up to 25% of cases that require an unacceptable dosage of corticosteroids to maintain remission, additional immunosuppression is used, including methotrexate, azathioprine, and mycophenolate mofetil. Regarding systemic sarcoidosis, infliximab and adalimumab have been successfully used for the treatment of refractory or sight-threatening disease. Optic neuropathy often affects women of African and Caribbean origin. Some authors recommend that patients be treated with high-dose corticosteroids and concurrent immunosuppression from the onset for this manifestation, which may be associated with a poorer outcome.

The French Agency for Health Safety of Products published recommendations of good practices (RGP) for the treatment of venous thromboembolic disease in 2009. Four of these recommendations apply to the initial management of the disease, with the objective of this study is to determine whether the development and diffusion of the four RGP has had an impact on the practice.A retrospective before/after study comparing 132 patients treated in emergency department of the Civil Hospices of Lyon for pulmonary embolism (PE) and/or deep venous thrombosis (DVT) in 2008-2009 ("before") and 153 patients in 2010-2011 ("after").In the "before" period, 70 patients were treated for DVT and 62 patients for PE. In the "after" period, 50 patients were treated for DVT and 103 patients for PE. The compliance rate was not significantly different for the two periods for each RGP except for the indication of low molecular weight Heparin (LMWH) or fondaparinux in the absence of severe renal failure (21% "before" vs. 45% "after"; P=0.02) for patients with PE. Management for the four recommendations was conform for 5.6% of eligible patients in the "before" period and for 3.7% for the "after" period.Our study shows that globally there is no impact of RGP. The reasons appear multiple with first, the mere dissemination and the absence of implementation of these guidelines.

International audience; The association between thymoma and autoimmunity is well known. Besides myasthenia gravis, which is found in 15 to 20% of patients with thymoma, other autoimmune diseases have been reported: erythroblastopenia, systemic lupus erythematosus, inflammatory myopathies, thyroid disorders, Isaac's syndrome or Good's syndrome. More anecdotally, Morvan's syndrome, limbic encephalitis, other autoimmune cytopenias, autoimmune hepatitis, and bullous skin diseases (pemphigus, lichen) have been reported. Autoimmune diseases occur most often before thymectomy, but they can be discovered at the time of surgery or later. Two situations require the systematic investigation of a thymoma: the occurrence of myasthenia gravis or autoimmune erythroblastopenia. Nevertheless, the late onset of systemic lupus erythematosus or the association of several autoimmune manifestations should lead to look for a thymoma. Neither the characteristics of the patients nor the pathological data can predict the occurrence of an autoimmune disease after thymectomy. Thus, thymectomy usefulness in the course of the autoimmune disease, except myasthenia gravis, has not been demonstrated. This seems to indicate the preponderant role of self-reactive T lymphocytes distributed in the peripheral immune system prior to surgery. Given the high infectious morbidity in patients with thymoma, immunoglobulin replacement therapy should be considered in patients with hypogammaglobulinemia who receive immunosuppressive therapy, even in the absence of prior infection

Introduction Une imagerie par resonance magnetique (IRM) cerebrale est tres frequemment realisee, dans le cadre du bilan etiologique des uveites, en particulier a la recherche d’une pathologie demyelinisante du systeme nerveux central. Plusieurs auteurs s’accordent sur le fait de ne pas recommander cet examen en l’absence de signe clinique au regard de sa faible rentabilite. L’objectif de cette etude est d’evaluer la pertinence de l’IRM cerebrale pour le diagnostic etiologique des uveites, en fonction de la presence de signes cliniques et du diagnostic suspecte initialement. Patients et methodes Nous avons etudie de maniere retrospective les dossiers de patients atteints d’uveite au centre hospitalo-universitaire de la Croix-Rousse a Lyon entre janvier 2003 et juillet 2018. Nous avons inclus, parmi les dossiers etudies, ceux ayant beneficies d’une IRM cerebrale pour le diagnostic etiologique de l’uveite. Le diagnostic de sclerose en plaques (SEP) a ete retenu en utilisant les criteres de Mc Donald [1] ou apres l’evaluation du centre de reference de la sclerose en plaques du CHU de Lyon. L’IRM cerebrale a ete consideree contributive si elle permettait de poser le diagnostic etiologique ou de redresser le diagnostic initialement suspecte. Resultats Parmi les 1215 patients atteints d’uveite, 402 (33,1 %) ont beneficie d’une IRM cerebrale. L’âge moyen au diagnostic etait de 45 ans et l’on retrouvait 229 femmes (57 %) et 173 hommes (43 %). Le type anatomique de l’uveite etait le suivant : uveites anterieures (16,4 %), intermediaires (29 %), posterieures (27 %), pan uveites (n = 109, 27 %). Les uveites etaient unilaterales dans 127 cas (31,6 %), chroniques dans 337 cas (83,8 %), granulomateuses dans 93 cas (23,1 %) et hypertensives dans 23 cas (5,7 %). L’IRM etait consideree comme anormale chez 80 patients (19,9 %), incluant des hypersignaux aspecificiques (n = 28, 35 %), des images de leucopathie vasculaire (n = 34, 42,5 %), des lesions inflammatoires (n = 13, 16,2 %), qui pour 12 patients repondaient aux criteres de Mac Donald ainsi que des lesions tumorales evocatrices de lymphome (n = 4, 5 %). La repartition etiologique a l’issue du bilan etait la suivante : uveites idiopathiques (45,8 %), uveites d’origine inflammatoire (25,1 %) incluant 67 sarcoidoses, 5 maladies de Behcet et 13 scleroses en plaques, entites ophtalmologiques (choroidite multifocale …) (18,4 %), etiologie infectieuse (7 %) et pseudo-uveites (3,7 %) dont 13 lymphomes oculo-cerebraux (LOC). L’IRM cerebrale a ete contributive dans 18 cas (4,5 %) incluant 4 cas de LOC, les 13 cas de SEP et 1 cas d’uveo-meningite tuberculeuse. Trente et un patients presentaient des signes neurologiques avant ou au moment de la realisation de l’IRM cerebrale ; pour 13 d’entre eux (36,1 %), l’IRM cerebrale a ete contributive au diagnostic etiologique de l’uveite. Pour les 18 patients chez qui l’IRM cerebrale etait contributive, 13 d’entre eux presentaient des signes neurologiques (72 %) avant ou au moment la realisation de l’examen. Discussion Les donnees concernant la rentabilite diagnostique de l’IRM cerebrale pour le diagnostic etiologique des uveites sont peu nombreuses et portent sur des effectifs reduits (168 et 66 patients respectivement) [2] , [3] . Notre etude est la premiere a evaluer l’apport de cette technique en regard de l’existence de signes neurologiques precedents ou au moment de sa realisation. Conclusion Alors que la prescription d’une IRM cerebrale pour le bilan etiologique d’une uveite est frequente, notre travail montre que cet examen n’est rentable que dans moins de 5 % des cas independamment des signes neurologiques. Il montre le plus souvent des anomalies non specifiques ou de lesions de leucopathie vasculaire. Dans moins de 1 % des cas, l’IRM cerebrale peut contribuer chez des patients asymptomatiques sur le plan neurologique au diagnostic de SEP ou LOC. En revanche chez des patients dont les IRM sont revenues contributives 75 % d’entre eux presentaient des signes neurologiques avant la realisation de l’imagerie.

Introduction Plusieurs etudes ont montre au cours du sepsis et du choc septique, une surmortalite des patients hypothermes en comparaison des patients normothermes ou febriles [1] , [2] . Cependant les caracteristiques (terrain, type d’infection) des patients hypothermes demeurent mal connues. Ce travail a pour objectif de decrire les caracteristiques des sujets bacteriemiques des urgences selon leur profil thermique, en se focalisant sur les hypothermes. Patients et methodes Etude observationnelle, retrospective, de juin 2011 a mai 2013, incluant tous les sujets bacteriemiques des urgences d’un centre hospitalo-universitaire. Les contaminations etaient exclues. Les donnees demographiques, clinicobiologiques, evolutives et celles concernant la prise en charge ont ete analysees (dossiers des urgences et dossiers des services d’aval). La mortalite a ete etudiee a j7, j28 et a 1 an. Les patients ont ete repartis en 3 groupes selon leur temperature tympanique a l’admission : hypothermes ( Resultats Au total, 406 episodes bacteriemiques ont ete identifies, incluant 18 hypothermes (4,4 %), 181 normothermes (44,6 %) et 207 febriles (51 %). Les hypothermes avaient plus de comorbidites (score de Charlson moyen a 4,6 vs 3,18 chez les normothermes et 3,1 chez les febriles ; p = 0,013). Les proportions d’insuffisance cardiaque, de demence et de cirrhose etaient plus elevees chez les hypothermes que chez les non-hypothermes. A l’admission, les hypothermes presentaient plus d’encephalopathie aigue et une pression arterielle moyenne (PAM) plus basse par rapport aux non-hypothermes tandis que l’indice de choc (FC/PAS) n’etait pas different. Les affections digestives chirurgicales etaient plus frequentes chez les hypothermes, notamment les ischemies mesenteriques (22 % des affections digestives chirurgicales chez les hypothermes vs 0 % chez les non-hypothermes). Les hypothermes avaient des valeurs d’uree, de taux de prothrombine et de transaminases plus elevees que les non-hypothermes. Les infections urinaires predominaient chez les non-hypothermes. Il n’existait pas de difference sur le type de germe incrimine selon la classification de Gram. La prise en charge therapeutique n’etait pas differente selon le profil thermique en termes de delai d’administration de l’antibiotherapie, d’adequation de l’antibiotherapie probabiliste et du delai de prise en charge chirurgicale. L’hypothermie etait associee a une surmortalite precoce (50 % de deces a j28 contre 13,8 % chez les normothermes et 5,8 % chez les febriles ; p Discussion Nos resultats montrent une surmortalite precoce mais egalement persistante a un an chez les hypothermes bacteriemiques et corroborent les donnees d’autres series de patients septiques, bacteriemiques ou non [1] , [2] , [3] . Notre travail montre une surrepresentation des patients cirrhotiques, dements et insuffisants cardiaques chez les patients hypothermes ; l’insuffisance cardiaque avait ete retrouvee par un precedent travail [1] . La gravite de la presentation initiale des hypothermes (PAM plus basse, encephalopathie septique, perturbations biologiques) avait deja ete soulignee [2] . Nos resultats confirment la relation entre mortalite et profil thermique, deja retrouvee il y a plus de 30 ans, avec une relation inversement proportionnelle a la temperature [3] . Conclusion Bien que non retenue dans la 3e definition internationale du sepsis, l’hypothermie, ancien critere de reponse inflammatoire systemique, devrait etre consideree comme un signe de gravite. Elle touche des sujets plus fragiles, avec insuffisance d’organe prealable (cœur, foie, systeme nerveux) et ne semble pas en lien avec un type de germe. La normothermie ne doit pas rassurer.

International audience; Adult-onset Still's disease is a rare and difficult to diagnose multisystemic disorder considered as a multigenic autoinflammatory syndrome. Its immunopathogenesis seems to be at the crossroads between inflammasomopathies and hemophagocytic lymphohistiocytosis, the most severe manifestation of the disease. According to recent insights in the pathophysiology and thanks to cohort studies and therapeutic trials, two phenotypes of adult-onset Still's disease may be distinguished: a systemic pattern, initially highly symptomatic and with a higher risk to exhibit life-threatening complications such as reactive hemophagocytic lymphohistiocytosis, where interleukin-1 blockade seems to be very effective, a chronic articular pattern, more indolent with arthritis in the foreground and less severe systemic manifestations, which would threat functional outcome and where interleukin-6 blockade seems to be more effective. This review focuses on these data.

- Abstract
Background/objectives: The large number and heterogeneity of causes of uveitis make the etiological diagnosis a complex task. The clinician must consider all the information concerning the ophthalmological and extra-ophthalmological features of the patient. Diagnostic machine learning algorithms have been developed and provide a correct diagnosis in one-half to three-quarters of cases. However, they are not integrated into daily clinical practice. The aim is to determine whether machine learning models can predict the etiological diagnosis of uveitis from clinical information., Methods: This cohort study was performed on uveitis patients with unknown etiology at first consultation. One hundred nine variables, including demographic, ophthalmic, and clinical information, associated with complementary exams were analyzed. Twenty-five causes of uveitis were included. A neural network was developed to predict the etiological diagnosis of uveitis. The performance of the model was evaluated and compared to a gold standard: etiological diagnosis established by a consensus of two uveitis experts., Results: A total of 375 patients were included in this analysis. Findings showed that the neural network type (Multilayer perceptron) (NN-MLP) presented the best prediction of the etiological diagnosis of uveitis. The NN-MLP's most probable diagnosis matched the senior clinician diagnosis in 292 of 375 patients (77.8%, 95% CI: 77.4-78.0). It achieved 93% accuracy (95% CI: 92.8-93.1%) when considering the two most probable diagnoses. The NN-MLP performed well in diagnosing idiopathic uveitis (sensitivity of 81% and specificity of 82%). For more than three-quarters of etiologies, our NN-MLP demonstrated good diagnostic performance (sensitivity > 70% and specificity > 80%)., Conclusion: Study results suggest that developing models for accurately predicting the etiological diagnosis of uveitis with undetermined etiology based on clinical information is feasible. Such NN-MLP could be used for the etiological assessments of uveitis with unknown etiology., Competing Interests: Competing interests: The authors declare no competing interests., (© 2024.

- Abstract
Systemic juvenile idiopathic arthritis (sJIA) and adult-onset Still's disease (AOSD) are considered the same disease, but a common approach for diagnosis and management is still missing., Methods: In May 2022, EULAR and PReS endorsed a proposal for a joint task force (TF) to develop recommendations for the diagnosis and management of sJIA and AOSD. The TF agreed during a first meeting to address four topics: similarity between sJIA and AOSD, diagnostic biomarkers, therapeutic targets and strategies and complications including macrophage activation syndrome (MAS). Systematic literature reviews were conducted accordingly., Results: The TF based their recommendations on four overarching principles, highlighting notably that sJIA and AOSD are one disease, to be designated by one name, Still's disease.Fourteen specific recommendations were issued. Two therapeutic targets were defined: clinically inactive disease (CID) and remission, that is, CID maintained for at least 6 months. The optimal therapeutic strategy relies on early use of interleukin (IL-1 or IL-6 inhibitors associated to short duration glucocorticoid (GC). MAS treatment should rely on high-dose GCs, IL-1 inhibitors, ciclosporin and interferon-γ inhibitors. A specific concern rose recently with cases of severe lung disease in children with Still's disease, for which T cell directed immunosuppressant are suggested. The recommendations emphasised the key role of expert centres for difficult-to-treat patients. All overarching principles and recommendations were agreed by over 80% of the TF experts with a high level of agreement., Conclusion: These recommendations are the first consensus for the diagnosis and management of children and adults with Still's disease., Competing Interests: Competing interests: BF: AbbVie, Amgen, Biogen, BMS, Celltrion, Fresenius Kabi, Galapagos, Gilead, Janssen, Lilly, Medac, MSD, Nordic Pharma, Novartis, Pfizer, Roche-Chugai, Sandoz, Sanofi-Genzyme, SOBI, UCB, Viatris; SM: BMS, Lilly, SOBI; JA: Sobi, Novartis, Roche, Pfizer, AbbVie, Lilly; AB: Boehringer Ingelheim, Novartis, AbbVie, Fresenius Kabi, GlaxoSmithKline; CB: SOBI; TC: AbbVie, Novartis, Roche; LD: AbbVie, Amgen, Astra-Zeneca, Boehringer-Ingelheim, BMS, Lilly, Galapagos, GlaxoSmithKline, Janssen, Kiniksa, Novartis, Pfizer, SOBI; ADB: Lenovo; EF: AbbVie, BMS, Galapagos, Lilly, Medac, Novartis, Sanofi, UCB, Pfizer, Roche, SOBI; DF: Boehringer-Ingelheim, SOBI, Novartis, Werfen Innova; MG, SGL, FM, FOR, SV: Novartis, SOBI; RG, AG: Novartis; IJ: Amgen, Lilly, Novartis, SOBI; PN: BMS, Brickell Bio, Cerecor, Exo Therapeutics, Miach Ortho, Novartis, Pfizer, SOBI, UpToDate, American Academy of Pediatrics; SO: Novartis, SOBI, Pfizer; PQ: Amgen, AbbVie, BMS, Roche-Chugai, Lilly, Novartis, Pfizer, Sanofi, SOBI, Health Events; PR: AbbVie, BMS, Janssen, Novartis, SOBI; SS: Novartis, SOBI, CSL Behring, Takeda, BioCryst, Biotest; M-ET: Boehringer-Ingelheim, Pfizer, Lilly, MSD, SOBI, Janssen, BMS, Fresenius Kabi, Galapagos, AbbVie; CW: Novartis, SOBI, UCB; LC: Meda Pharma, Angelini Pharma, Pfizer, SANOFI-AVENTIS, Fresenius Kabi, Galapagos; FDB: SOBI, Novartis, Apollo, Kiniksa, Sanofi, Roche, Elixiron, Regeneron; ADM, SB, KL, CL, ES, T-CW: none., (© European Alliance of Associations for Rheumatology, EULAR 2024.

- Abstract
Purpose: Determining uveitis etiology is a challenge. It is based primarily on demographic data and the characteristics of eye examination. It is not clear to what extent extraocular physical signs contribute to elucidating the etiology. This study aimed to establish the contribution of the clinical extra-ophthalmological features for the assessment of the underlying etiology of uveitis., Methods: We retrospectively reviewed 1307 patients with uveitis referred to our tertiary center between 2003 and 2021. Uveitis was classified according to the Standardization of Uveitis Nomenclature. Clinical features were collected at diagnosis by internists before the etiological diagnosis was made. The main outcome description was the contribution of clinical features., Results: Clinical extra-ophthalmological features contributed to the assessment of the underlying etiology of uveitis in 363 (27.8%) patients. The joint and the skin examinations were the most useful for etiological investigations, respectively in 12.3% and 11.8% of patients. Five etiologies of uveitis accounted for 80% of the cases: sarcoidosis, HLA-B27-related uveitis, Behçet's disease, multiple sclerosis, and Vogt-Koyanagi-Harada disease. Clinical extra-ophthalmological features were particularly important in the etiological diagnosis of acute bilateral anterior uveitis and panuveitis., Conclusion: This study suggests that clinical extra-ophthalmological features are essential for the etiological diagnosis of uveitis in more than a quarter of patients. It demonstrates once again the value of collaboration between ophthalmologists and other specialists experienced in performing extra-ophthalmological clinical examinations, particularly in patients with acute bilateral anterior uveitis and panuveitis.

- Abstract
Objectives: Vacuoles, E1 enzyme, X-linked, autoinflammatory and somatic (VEXAS) syndrome is an adult-onset autoinflammatory disease associated with somatic ubiquitin-like modifier-activating enzyme 1 (UBA1) mutations. We aimed to evaluate the efficacy and safety of targeted therapies., Methods: Multicentre retrospective study including patients with genetically proven VEXAS syndrome who had received at least one targeted therapy. Complete response (CR) was defined by a clinical remission, C-reactive protein (CRP) ≤10 mg/L and a ≤10 mg/day of prednisone-equivalent therapy, and partial response (PR) was defined by a clinical remission and a 50% reduction in CRP levels and glucocorticoid dose., Results: 110 patients (median age 71 (68-79) years) who received 194 targeted therapies were included: 78 (40%) received Janus kinase (JAK) inhibitors (JAKi), 51 (26%) interleukin (IL)-6 inhibitors, 33 (17%) IL-1 inhibitors, 20 (10%) tumour necrosis factor (TNFα) blockers and 12 (6%) other targeted therapies. At 3 months, the overall response (CR and PR) rate was 24% with JAKi, 32% with IL-6 inhibitors, 9% with anti-IL-1 and 0% with TNFα blockers or other targeted therapies. At 6 months, the overall response rate was 30% with JAKi and 26% with IL-6 inhibitors. Survival without treatment discontinuation was significantly longer with JAKi than with the other targeted therapies. Among patients who discontinued treatment, causes were primary failure, secondary failure, serious adverse event or death in 43%, 14%, 19% and 19%, respectively, with JAKi and 46%, 11%, 31% and 9%, respectively, with IL-6 inhibitors., Conclusions: This study shows the benefit of JAKi and IL-6 inhibitors, whereas other therapies have lower efficacy. These results need to be confirmed in prospective trials., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024. No commercial re-use.

- Abstract
Granulomatous myositis is a clinical-pathological entity, which has been rarely reported, mostly described in sarcoidosis. Currently, no clear and simple prognostic factor has been identified to predict granulomatous myositis evolution. The clinical, anatomopathological, imaging, and biological characteristics of 26 patients with granulomatous myositis were retrospectively collected to describe clinical presentation and outcomes of this condition. Twenty-six patients with granulomatous myositis were included (14 males) with a median age of symptom onset of 65 years. 54 % of patients presented a severe form of the disease defined as a Rankin score ≥2 at last follow-up visit or a progressive form of the disease (no improvement under treatment). Etiology were sarcoidosis (n = 14), inclusion body myositis (n = 4), autoimmune disease (n = 1), hematological malignancy (n = 1), and idiopathic (n = 6). Distal deficit and amyotrophy were more frequent among those with a severe disease. Corticosteroids led to improvement in 75 % of cases, but 66 % of responders relapsed. Methotrexate appeared as a promising second line therapy with clinical improvement in 50 % of patients, and no relapse in responders. Granulomatous myositis is often a severe and difficult-to-treat disease in which patients frequently progress towards severe disability. The presence of muscle atrophy and distal weakness appears to be frequently associated with a severe form of the disease., Competing Interests: Declaration of competing interest The authors have no conflicts of interest to declare., (Copyright © 2024.

- Abstract
Background: The objective was to assess the agreement between therapeutic proposals derived from basic critical care echocardiography performed by novice operators in ultrasonography after a limited training (residents) and by experts considered as reference. Secondary objectives were to assess the agreement between operators' answers to simple clinical questions and the concordance between basic two-dimensional measurements., Methods: This observational, prospective, single-center study was conducted over a 3-year period in a medical-surgical intensive care unit. Adult patients with acute circulatory and/or respiratory failure requiring a transthoracic echocardiography (TTE) examination were studied. In each patient, a TTE was performed by a resident novice in ultrasonography after a short training program and by an expert, independently but within 1 h and in random order. Each operator addressed standardized simple clinical questions and subsequently proposed a therapeutic strategy based on a predefined algorithm., Results: Residents performed an average of 33 TTE studies in 244 patients (156 men; age: 63 years [52-74]; SAPS2: 45 [34-59]; 182 (75%) mechanically ventilated). Agreement between the therapeutic proposals of residents and experienced operators was good-to-excellent. The concordance was excellent for suggesting fluid loading, inotrope or vasopressor support (all Kappa values > 0.80). Inter-observer agreement was only moderate when considering the indication of negative fluid balance (Kappa: 0.65; 95% CI 0.50-0.80), since residents proposed diuretics in 23 patients (9.5%) while their counterparts had the same suggestion in 35 patients (14.4%). Overall agreement of responses to simple clinical questions was also good-to-excellent. Intraclass correlation coefficient exceeded 0.75 for measurement of ventricular and inferior vena cava size., Conclusions: A limited training program aiming at acquiring the basic level in critical care echocardiography enables ICU residents novice in ultrasonography to propose therapeutic interventions with a good-to-excellent agreement with experienced operators., (© 2024.

- Abstract
NLRP3-associated autoinflammatory disease is a heterogenous group of monogenic conditions caused by NLRP3 gain-of-function mutations. The poor functional characterization of most NLRP3 variants hinders diagnosis despite efficient anti-IL-1 treatments. Additionally, while NLRP3 is controlled by priming and activation signals, gain-of-functions have only been investigated in response to priming. Here, we characterize 34 NLRP3 variants in vitro, evaluating their activity upon induction, priming, and/or activation signals, and their sensitivity to four inhibitors. We highlight the functional diversity of the gain-of-function mutants and describe four groups based on the signals governing their activation, correlating partly with the symptom severity. We identify a new group of NLRP3 mutants responding to the activation signal without priming, associated with frequent misdiagnoses. Our results identify key NLRP3 residues controlling inflammasome activity and sensitivity to inhibitors, and antagonistic mechanisms with broader efficacy for therapeutic strategies. They provide new insights into NLRP3 activation, an explanatory mechanism for NLRP3-AID heterogeneity, and original tools for NLRP3-AID diagnosis and drug development., (© 2024 Cosson et al.)

- Abstract
Objective: FMF is the most common monogenic autoinflammatory disease associated with MEFV mutations. Disease phenotype and response to treatment vary from one patient to another, despite similar genotype, suggesting the role of environmental factors. The objective of this study was to analyse the gut microbiota of a large cohort of FMF patients in relation to disease characteristics., Methods: The gut microbiotas of 119 FMF patients and 61 healthy controls were analysed using 16 s rRNA gene sequencing. Associations between bacterial taxa, clinical characteristics, and genotypes were evaluated using multivariable association with linear models (MaAslin2), adjusting on age, sex, genotype, presence of AA amyloidosis (n = 17), hepatopathy (n = 5), colchicine intake, colchicine resistance (n = 27), use of biotherapy (n = 10), CRP levels, and number of daily faeces. Bacterial network structures were also analysed., Results: The gut microbiotas of FMF patients differ from those of controls in having increased pro-inflammatory bacteria, such as the Enterobacter, Klebsiella and Ruminococcus gnavus group. Disease characteristics and resistance to colchicine correlated with homozygous mutations and were associated with specific microbiota alteration. Colchicine treatment was associated with the expansion of anti-inflammatory taxa such as Faecalibacterium and Roseburia, while FMF severity was associated with expansion of the Ruminococcus gnavus group and Paracoccus. Colchicine-resistant patients exhibited an alteration of the bacterial network structure, with decreased intertaxa connectivity., Conclusion: The gut microbiota of FMF patients correlates with disease characteristics and severity, with an increase in pro-inflammatory taxa in the most severe patients. This suggests a specific role for the gut microbiota in shaping FMF outcomes and response to treatment., (© The Author(s) 2023.
