Background: It is unclear whether hereditary hemorrhagic telangiectasia (HHT) patients can tolerate antithrombotic therapies (AT) including antiplatelet (AP) and/or anticoagulant (AC) agents., Objectives: Primary endpoint was tolerance to AT in HHT. Secondary endpoints were to identify factors associated with major bleeding events (MBE) and premature discontinuation of AT., Methods: Retrospective multicenter study in French national HHT Registry patients exposed to AT., Results: We included 126 patients with 180 courses of AT. Median follow-up was 24 [11-52] months. Mean age was 65.6 ± 13.1 years. The first 3 months of AT exposure had an increased risk of hospitalization for hemorrhage (p < 0.001) and transfusions (p < 0.001). MBE (n = 63) occurred more frequently in the first 3 months of AT exposure (p < 0.001). Premature discontinuation of AT occurred in 61 cases. Rate of premature discontinuation was 29 % under both AP and AT therapy but significantly higher under dual AP therapy (n = 4/7, 57 % p = 0.008). Risk factors for MBE were: age ≥ 60 years (HR 2.34 [1.12;4.87], p = 0.023), prior hospitalization in the 3 months before starting AT for hemorrhage (HR 3.59 [1.93;6.66], p < 0.001) or transfusion (HR 3.15 [1.61;6.18], p = 0.001), previous history of gastro-intestinal bleeding (HR 2.71 [1.57;4.65], p < 0.001) or MBE (HR 4.62 [2.68;7.98], p < 0.001). Frequency of MBE did not differ between groups except for a higher risk in the dual AP group (HR 3.92 [1.37;11.22], p = 0.011)., Conclusion: Tolerance of AC or AP therapy was similar in HHT population but not dual AP therapy. We identified risk factors for MBE occurrence or premature discontinuation under AT., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Only one author have potential conflict of interest: L.

Background: EPHB4 loss of function is associated with type 2 capillary malformation-arteriovenous malformation syndrome, an autosomal dominant vascular disorder. The phenotype partially overlaps with hereditary haemorrhagic telangiectasia (HHT) due to epistaxis, telangiectases and cerebral arteriovenous malformations, but a similar liver involvement has never been described., Methods: Members of the French HHT network reported their cases of EPHB4 mutation identified after an initial suspicion of HHT. Clinical, radiological and genetic characteristics were analysed., Results: Among 21 patients with EPHB4 , 15 had a liver imaging, including 7 with HHT-like abnormalities (2 female patients and 5 male patients, ages 43-69 years). Atypical epistaxis and telangiectases were noted in two cases each. They were significantly older than the eight patients with normal imaging (median: 51 vs 20 years, p<0.0006).The main hepatic artery was dilated in all the cases (diameter: 8-11 mm). Six patients had hepatic telangiectases. All kind of shunts were described (arteriosystemic: five patients, arterioportal: two patients, portosystemic: three patients). The overall liver appearance was considered as typical of HHT in six cases.Six EPHB4 variants were classified as pathogenic and one as likely pathogenic, with no specific hot spot., Conclusion: EPHB4 loss-of-function variants can be associated with HHT-like hepatic abnormalities and should be tested for atypical HHT presentations., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Objectives: In this large multicentre study, we compared the effectiveness and safety of tocilizumab intravenous versus subcutaneous (SC) in 109 Takayasu arteritis (TAK) patients., Methods: We conducted a retrospective multicentre study in referral centres from France, Italy, Spain, Armenia, Israel, Japan, Tunisia and Russia regarding biological-targeted therapies in TAK, since January 2017 to September 2019., Results: A total of 109 TAK patients received at least 3 months tocilizumab therapy and were included in this study. Among them, 91 and 18 patients received intravenous and SC tocilizumab, respectively. A complete response (NIH <2 with less than 7.5 mg/day of prednisone) at 6 months was evidenced in 69% of TAK patients, of whom 57 (70%) and 11 (69%) patients were on intravenous and SC tocilizumab, respectively (p=0.95). The factors associated with complete response to tocilizumab at 6 months in multivariate analysis, only age <30 years (OR 2.85, 95% CI 1.14 to 7.12; p=0.027) and time between TAK diagnosis and tocilizumab initiation (OR 1.18, 95% CI 1.02 to 1.36; p=0.034). During the median follow-up of 30.1 months (0.4; 105.8) and 10.8 (0.1; 46.4) (p<0.0001) in patients who received tocilizumab in intravenous and SC forms, respectively, the risk of relapse was significantly higher in TAK patients on SC tocilizumab (HR=2.55, 95% CI 1.08 to 6.02; p=0.033). The overall cumulative incidence of relapse at 12 months in TAK patients was at 13.7% (95% CI 7.6% to 21.5%), with 10.3% (95% CI 4.8% to 18.4%) for those on intravenous tocilizumab vs 30.9% (95% CI 10.5% to 54.2%) for patients receiving SC tocilizumab. Adverse events occurred in 14 (15%) patients on intravenous route and in 2 (11%) on SC tocilizumab., Conclusion: In this study, we confirm that tocilizumab is effective in TAK, with complete remission being achieving by 70% of disease-modifying antirheumatic drugs-refractory TAK patients at 6 months., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Background: Tocilizumab and anakinra are anti-interleukin drugs to treat severe coronavirus disease 2019 (COVID-19) refractory to corticosteroids. However, no studies compared the efficacy of tocilizumab versus anakinra to guide the choice of the therapy in clinical practice. We aimed to compare the outcomes of COVID-19 patients treated with tocilizumab or anakinra., Methods: Our retrospective study was conducted in three French university hospitals between February 2021 and February 2022 and included all the consecutive hospitalized patients with a laboratory-confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection assessed by RT-PCR who were treated with tocilizumab or anakinra. A propensity score matching was performed to minimize confounding effects due to the non-random allocation., Results: Among 235 patients (mean age, 72 years; 60.9% of male patients), the 28-day mortality (29.4% vs. 31.2%, p = 0.76), the in-hospital mortality (31.7% vs. 33.0%, p = 0.83), the high-flow oxygen requirement (17.5% vs. 18.3%, p = 0.86), the intensive care unit admission rate (30.8% vs. 22.2%, p = 0.30), and the mechanical ventilation rate (15.4% vs. 11.1%, p = 0.50) were similar in patients receiving tocilizumab and those receiving anakinra. After propensity score matching, the 28-day mortality (29.1% vs. 30.4%, p = 1) and the rate of high-flow oxygen requirement (10.1% vs. 21.5%, p = 0.081) did not differ between patients receiving tocilizumab or anakinra. Secondary infection rates were similar between the tocilizumab and anakinra groups (6.3% vs. 9.2%, p = 0.44)., Conclusion: Our study showed comparable efficacy and safety profiles of tocilizumab and anakinra to treat severe COVID-19., Competing Interests: GK has received from ROCHE-CHUGAI Research Grants <€20,000 and fees from Sobi France for scientific presentations <€4,000 and participated in a SOBI Advisory Board on COVID unpaid and an OLATEC Monitoring Board unpaid.

Background: Hereditary hemorrhagic telangiectasia (HHT) disease is a rare genetic disorder with symptoms and complications that can significantly affect patients' daily lives. To date, no scale has been validated to assess the specific symptoms of this disease on the quality of life (QOL) of HHT patients. This makes it difficult for clinicians to accurately measure the quality of life of patients with HHT. The present study aims to develop and validate a QOL measurement tool specific to HHT disease: the QOL questionnaire in HHT (QoL-HHT)., Methods: A quantitative, non-interventional, multi-center study involving HHT patients in twenty French HHT expert centers was conducted. A calibration sample of 415 HHT patients and a validation sample of 228 HHT patients voluntarily participated in the study. Data were analyzed using exploratory factor analysis (EFA), confirmatory factor analysis (CFA), Exploratory Structural Equation Modeling (ESEM) analyses, reliability analyses, and correlational analyses., Results: The EFA, CFA and ESEM results allowed us to provide evidence of the factorial structure of a questionnaire composed of 24 items measuring 6 domains of QOL: Physical limitations, social relationships, concern about bleeding, relationship with the medical profession, experience of symptoms, and concern about the evolution of the disease. Cronbach's alpha coefficients (> 0.70) demonstrated reliable internal consistency of all the QoL-HHT scores (dimensions). The results of the test-retest provided further evidence of the reliability of the QOL-HHT scores over time. Correlational analyses provided evidence for the convergent validity of the QoL-HHT scores., Conclusions: We developed a simple and quick self-assessment tool to measure quality of life specific to HHT disease. This study demonstrated reliability and validity of our QoL-HHT scores. It is a very promising tool to evaluate the impact of HHT disease on all aspects of the quality of life of HHT patients in order to offer them individualized medico-psycho-social support., Trial Registration: ClinicalTrials, NCT03695874.

Objective: A new adult-onset autoinflammatory syndrome has been described, named VEXAS (Vacuoles, E1 Enzyme, X-linked, Autoinflammatory, Somatic). We aimed to compare the clinical characteristics, the laboratory features and the outcomes between idiopathic-relapsing polychondritis (I-RP) and VEXAS-relapsing polychondritis (VEXAS-RP)., Methods: Patients from French retrospective multicentre cohort of RP were separated into two groups: a VEXAS-RP and an I-RP., Results: Compared with patients with I-RP (n=40), patients with VEXAS-RP (n=55) were men (96% vs 30%, p<0.001) and were older at diagnosis (66 vs 44 years, p<0.001). They had a greater prevalence of fever (60% vs 10%, p<0.001), of skin lesions (82% vs 20%, p<0.001), of ocular involvement (57% vs 28%, p=0.01), of pulmonary infiltrates (46% vs 0%, p<0.001), of heart involvement (11% vs 0%, p=0.0336) and with higher median C-reactive protein levels (64 mg/L vs 10 mg/L, p<0.001). Seventy-five per cent of the patients with VEXAS-RP had myelodysplastic syndrome (MDS) versus none in I-RP group. The glucocorticoids use, and the number of steroid sparing agents were similar in both groups, but patients with VEXAS-RP had more frequent refractory disease (remission obtained in 27% vs 90%, p<0001). VEXAS-RP was associated with higher risk of death: six patients (11%) died in the VEXAS-RP group after a median follow-up of 37 months and none in the I-RP group after a median follow-up of 92 months (p<0.05)., Conclusion: We report the largest cohort of VEXAS-RP, characterised by high prevalence of male sex, fever, skin lesion, ocular involvement, pulmonary infiltration, heart involvement, older age and MDS association., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Objective: To assess the safety and the efficacy of TNF-α antagonists and tocilizumab in patients with Takayasu arteritis (TAK)., Methods: A total of 209 patients with TAK [median age 29 years (interquartile range 7-62)], 186 (89%) females] were included. They received either TNF-α antagonists [n = 132 (63%) with 172 lines; infliximab (n = 109), adalimumab (n = 45), golimumab (n = 8), certolizumab (n = 6) and etanercept (n = 5)] or tocilizumab [n = 77 (37%) with 121 lines; i.v. and s.c. in 95 and 26 cases, respectively]., Results: A complete response at 6 months was evidenced in 101/152 (66%) patients on TNF-α antagonists and 75/107 (70%) patients on tocilizumab. Age ≥30 years [odds ratio 2.09 (95% CI 1.09, 3.99)] was associated with complete response, whereas vascular signs [OR 0.26 (95% CI 0.1, 0.65)], baseline prednisone ≥20 mg/day [OR 0.51 (95% CI 0.28, 0.93)] were negatively associated with the complete response to TNF-α antagonists or tocilizumab. During a median follow-up of 36 months, 103 relapses were noted. Supra-aortic branches and thoracic aorta involvement [HR 2.44 (95% CI 1.06, 5.65) and 3.66 (1.18, 11.4), respectively] and systemic signs at baseline [HR 2.01 (95% CI 1.30, 3.11)] were significantly associated with relapse. The cumulative incidence of treatment discontinuation and relapse were similar in TNF-α antagonists and tocilizumab. Fifty-eight (20%) adverse effects occurred on biologic targeted therapies [37 (21%) on TNF-α antagonists and 21 (17%) on tocilizumab (P = 0.4), respectively]., Conclusion: This large multicentre study shows high efficacy of biologic targeted treatments in refractory TAK. Efficacy, relapse and drug retention rate were equivalent with TNF-α antagonists and tocilizumab., (© The Author(s) 2021.

Acute severe hepatitis is a rare complication of adult-onset Still's disease (AOSD). This condition is poorly characterized. We performed a review of the medical literature to describe clinical, biological, pathological, and treatment characteristics from AOSD patients with acute severe hepatitis. Their characteristics were compared with AOSD patients without severe hepatitis. Twenty-one cases were collected including a new case reported here. Patients with severe hepatitis were mostly young adults with a median age of 28 years (range: 20 to 55 years). Overall, patients with severe hepatitis had less arthritis, macular rash, sore throat, lymphadenopathy, or splenomegaly than patients without severe hepatitis. Cytopenia was more frequent in case of severe hepatitis. Most patients were treated with steroids, and the use of biotherapies has increased over the last decade. Despite treatment, 49% of patients required liver transplantation and 24% died. Key Points • Acute severe hepatitis in adult-onset Still's disease (AOSD) is associated with liver transplantation and/or death in, respectively, 43% and 24% of cases. • Severe hepatitis is the inaugural manifestation of AOSD in half of cases. Diagnosis is difficult when extra-hepatic clinical manifestations are lacking. • The mechanism of hepatic necrosis in AOSD with severe hepatitis is unknown. Liver biopsy is not specific and should not delay treatment initiation.

Myelodysplastic syndromes (MDS) and chronic myelomonocytic leukemia (CMML) are associated with systemic inflammatory or autoimmune diseases in 10-20 % of cases. Among them, immune thrombocytopenia (ITP) has been reported but large studies assessing this association are missing. Whether such patients have a particular phenotype and require particular management is unclear. This study analyzes the clinical spectrum, outcome and therapeutic management of patients with ITP associated with MDS or CMML, in comparison (i) to patients with primary ITP without MDS/CMML and (ii) to patients with MDS/CMML without ITP. Forty-one MDS/CMML-associated ITP patients were included, with chronic ITP in 26 (63%) patients, low-risk myelodysplasia in 30 (73%) patients and CMML in 24 (59%) patients. An associated autoimmune disease was noted in 10 (24%) patients. In comparison to primary ITP patients, MDS/CMML-associated ITP patients had a higher occurrence of severe bleeding despite similar platelet counts at diagnosis. First-line treatment consisted of glucocorticoids (98%) and intravenous immunoglobulin (IVIg) (56%). Response achievement with IVIg was more frequent in primary ITP than in MDS/CMML-associated ITP patients. Response rates to second-line therapies were not statistically different between primary ITP and MDS/CMMLassociated ITP patients. Ten percent (n=4) of patients with MDS/CMML-associated ITP had multirefractory ITP versus none in primary ITP controls. After a median follow-up of 60 months, there was no difference in overall survival between MDS/CMML-associated ITP and primary ITP patients. Leukemia-free-survival was significantly better in MDS/CMMLassociated ITP patients than in MDS/CMML without ITP MDS/CMML-associated ITP have a particular outcome with more severe bleeding and multirefractory profile than primary ITP, similar response profile to primary ITP therapy except for IVIg, and less progression toward acute myeloid leukemia than MDS/CMML without ITP.

Introduction: Our objective was to evaluate characteristics, treatment and outcome of vasculitis associated with myelodysplastic syndrome (MDS) and chronic myelomonicytic leukemia (CMML) PATIENTS AND METHODS: Retrospective descriptive analysis of MDS/CMML-related vasculitis and comparison with MDS/CMML patients without dysimmune features., Results: Seventy patients with vasculitis and MDS/CMML were included, with median age of 71.5 [21-90] years and male/female ratio of 2.3. Vasculitis was diagnosed prior to MDS/CMML in 31 patients (44%), and after in 20 patients. In comparison with MDS/CMML without autoimmune/inflammatory features, vasculitis with MDS/MPN showed no difference in MDS/CMML subtypes distribution nor International Prognostic Scoring System and CMML-specific prognostic (IPSS/CPSS) scores. Vasculitis subtypes included Giant cell arteritis in 24 patients (34%), Behçet's-like syndrome in 11 patients (20%) and polyarteritis nodosa in 6 patients (9%). Glucocorticoids (GCs) were used as first-line therapy for MDS/CMML vasculitis in 64/70 patients (91%) and 41 (59%) received combined immunosuppressive therapies during the follow-up. After a median follow-up of 33.2 months [1-162], 31 patients (44%) achieved sustained remission. At least one relapse occurred in 43 patients (61%). Relapse rates were higher in patients treated with conventional Disease Modifying Anti-Rheumatic Drug (DMARDs) (odds ratio 4.86 [95% CI 1.38 - 17.10]), but did not differ for biologics (odds ratio 0.59 [95% CI 0.11-3.20]) and azacytidine (odds ratio 1.44 [95% CI 0.21-9.76]) than under glucocorticoids. Overall survival in MDS/CMML vasculitis was not significantly different from MDS/CMML patients without autoimmune/inflammatory features (p = 0.5), but acute leukemia progression rates were decreased (log rank <0.05)., Conclusion: This study shows no correlation of vasculitis diagnoses with subtypes and severity of MDS/CMML, and no significant impact of vasculitis on overall survival. Whereas conventional DMARDs seem to be less effective, biologics or azacytidine therapy could be considered for even low-risk MDS/CMML vasculitis., (Copyright © 2020 Elsevier Inc.

Objectives: Blood transcriptomic IFN signature is a hallmark of SLE. The impaired health-related quality of life (HRQOL) observed in SLE is poorly related to disease activity. The aim of this study was to test how IFN signatures were associated with HRQOL in SLE patients., Methods: Among consecutive patients, blood transcriptomic profiles were analysed with a modular framework comprising 3 IFN modules: M1.2, M3.4 and M5.12. Disease activity was evaluated by the SLEDAI score, and HRQOL was assessed with the SF-36 questionnaire, which includes eight domains: physical function, role physical, bodily pain, general health, vitality, social functioning, role emotional, and mental health (MH) and physical component summary and mental component summary scores., Results: A total of 57 SLE patients were evaluated, among whom 27 (47%) were clinically quiescent, 30 (53%) were flaring, and 19 (33%) had active lupus nephritis. All SF-36 domains were altered in SLE patients compared with the general French population (P < 0.0001). In multivariate analysis, taking into account flares, age, ethnicity, smoking and renal severity, social functioning was independently associated with the IFN score (P = 0.027). Analyses restrained to quiescent patients (n = 27) yielded greater associations between social functioning and the three IFN modules, and between MH and M3.4. Considering all quiescent visits (n = 51), the IFN score was independently correlated with social functioning (P = 0.022) and MH (P = 0.038)., Conclusion: This unexpected paradoxical association between IFN signature and some specific HRQOL domains argues against a pivotal role of IFNs in the persistently altered HRQOL of SLE patients., (© The Author(s) 2019.

IgG4-related disease is a chronic inflammatory disease characterized by clinical, biological and pathological unifying findings. Because these criteria are not always all together available in patients and because biological and pathological markers are not totally specific, the diagnosis should be retained after exclusion of mimickers. Since the individualization of IgG4-RD, several studies have allowed to better characterize immunological abnormalities associated with this particular condition. B and T cell oligoclonal activation is associated with T helper 2 cytokine production leading to IgG4 production and profibrotic cytokine release. A central role for T follicular helper 2 cells is suggested from recent findings. We summarize here recent advances in understanding of immune abnormalities in IgG4-related disease., (Copyright © 2020 Elsevier Masson SAS. All rights reserved.)

Pachymeningitis is rare, either idiopathic or secondary to inflammatory disorders, after tumoral, surgical or infectious causes have been excluded. The fibroinflammatory IgG4-related disease is one of the etiologies of pachymeningitis with only few cases reported yet. From a single referral regional center, we evaluated the frequency of IgG4-related disease as the cause of inflammatory pachymeningitis in 10% of cases. From a National case registry of IgG4-related disease the pachymeningitis frequency was 4.1%. We report eight new cases with cranial, spinal or both involvements and a literature review of 46 pathological proven cases. We observed that IgG4-related pachymeningitis is in most cases not associated to extra-neurological manifestations of the disease. Only 27% of spinal and 40% of cranial IgG4-related pachymeningitis are associated with other disease localizations. First line treatment strategies included surgery and steroids. The use of immunosuppressants or rituximab was necessary in 18% of spinal and 54% of cranial localizations. Some patients remained with sequellae and clinical and/or radiological improvement can be difficult to obtain., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Introduction/objectives: The aim of our study was to investigate possible differences in nailfold videocapillaroscopy (NVC) features between patients with dermatomyositis (DM), overlap myositis (OM), antisynthetase syndrome (ASS), and immune-mediated necrotizing myopathy (IMNM)., Methods: We performed a cross-sectional monocentric study. All patients with inflammatory myopathies (IMs) over a 6-month period were analyzed by NVC for giant and ramified capillaries, tortuosities, capillary density, disorganization, and scleroderma pattern. Clinical, biological, and pathological characteristics were retrospectively recorded. Patients were classified as having DM, OM, ASS, or IMNM for comparison. Patients were also compared with a group of patients with systemic sclerosis (SSc)., Results: NVC was analyzed in DM (n = 17), OM (n = 8), ASS (n = 12), and IMNM (n = 6). Vascular disorganization and avascular zones were observed only in DM (11.8%) and OM (62.5%). The percentage of patients with giant capillaries was higher in OM (n = 4/8) than in DM (n = 3/17) and absent in ASS and IMNM. Frequency of ramified capillaries, tortuosities, hemorrhages, or thrombosis was not different between subgroups. A scleroderma pattern was only observed in OM patients., Conclusion: In this limited series of patients, we observed that DM and OM NVC abnormalities are different from ASS and IMNM. We could not determine NVC specific patterns associated with myositis-specific antibody subtypes of DM because of the small number of patients.Key Points• Nailfold videocapillaroscopy abnormalities are different in subgroups of inflammatory myopathies.• Giant capillaries, disorganization, and major capillary loss are observed in overlap myositis and dermatomyositis but not in antisynthetase syndrome (ASS) or immune-mediated necrotizing myopathy.• Nailfold videocapillaroscopy abnormalities in overlap myositis (with the exclusion of ASS) are close to systemic sclerosis.

Purpose: Neonatal immune neutropenia is observed in rare cases in newborns from mothers with idiopathic or autoimmune neutropenia, secondary to passive transfer of maternal granulocyte auto-antibodies., Methods: We performed a literature review and report four supplementary cases from the French registry of neutropenia., Results: Only 14 cases (11 mothers, 14 newborns) have been reported. Granulocyte aggregation (GAT) and granulocyte indirect immunofluorescence test (GIFT) are the recommended laboratory procedures for antibody detection. Monoclonal antibody-specific immobilization of granulocyte antigens (MAIGA)-confirmed antibody specificity. Antibody detection in newborns is not generally possible owing to extreme neutropenia. In half of the cases autoantibodies against neutrophils (AAN) were positive in maternal sera (7 out of 11). In some newborns tested, IgG + AAN were also positive, with disappearance in parallel of spontaneous neutrophil count improvement. No correlation between maternal type of AAN and titer and neonatal neutropenia can be established. Neutropenia resolved spontaneously between 2 weeks and 4 months. Infections in newborns were observed in 43% of cases, with no deaths reported. Granulocyte colony-stimulating factor (G-CSF) was administered to some newborns (5 out of 14) in the case of infections. Low-dose G-CSF administered to childbearing women during pregnancy could be proposed to prevent neutropenia in newborns., Conclusions: From the few cases reported so far it is impossible to draw any conclusions regarding frequency, risk factors, and outcome, but the overall prognosis for newborns seems good. Because it can be associated with potentially severe neonatal infections, autoimmune neutropenia in childbearing mothers should be closely monitored in collaboration with gynecologists and pediatricians.

Background: We conducted a monocentric retrospective study of patients with myelodysplastic syndromes (MDS) and autoimmune or inflammatory disorders (AIMs) and a literature review. We analyzed the association with subgroups of the WHO 2016 MDS classification and patient's survival in a case control study. Risk factors associated with survival were analyzed by uni- and multivariate analysis., Results: From all MDS patients 11% presented with AIMs. These were heterogeneous and the most frequent where polyarthritis (25%) and autoimmune cytopenias (17%). No difference for frequency and type of AIMs was observed for the WHO 2016 MDS subgroups (p = .3). In the case control study WHO classification, karyotype abnormalities, IPSS-R and IPSS were similar in both groups. The overall survival from MDS diagnosis was better in the group with AIMs [10.3 ± 0.6 (IC95% 6.2-12.9) versus 4.8 ± 1.1 years (IC95% 4.2-8.7), p = .04]. The better survival was restricted to MDS with low or intermediate-1 IPSS [11.1 ± 1.5 (IC95% 9.9-NR) versus 8.7 ± 1.3 years (IC95% 4.8-10.3), p = .006]. The better survival was only observed when AIMs diagnosis was timely associated or appeared after MDS diagnosis (p = .04). Factors associated with a better overall survival and survival without AML were steroid dependence [respectively HR = 0.042, p = .003, (IC95% 0.005-0.33) and HR = 0.07, p = .002, (IC95% 0.013-0.39)], a diagnosis of AIMs and MDS timely associated [respectively HR = 0.05, p = .009, (IC95% 0.006-0.478) and HR = 0.1, p = .008, (IC95% 0.018-0.54)] or a diagnosis of AIMs after MDS [respectively HR = 0.024, p = .009, (IC95% 0.001-0.39) and HR = 0.04, p = .008, (IC95% 0.003-0.43)]., Conclusion: Autoimmune and inflammatory diseases associated to MDS are heterogeneous. AIMs diagnosed after or concomitantly to MDS seems associated with a better survival. Prospective studies are necessary to demonstrate that autoimmunity is associated to a better control of the MDS clone., (Copyright © 2018 Elsevier B.V. All rights reserved.)

Background: Alemtuzumab is a humanized monoclonal antibody directed at CD52 approved as a disease-modifying therapy for relapsing forms of multiple sclerosis (MS)., Objective: To describe a case of a life-threatening autoimmune anemia occurring after a first course of alemtuzumab for relapsing-remitting MS in a 28-year-old male., Methods: Case report., Results: A 28-year-old male developed a life-threatening autoimmune anemia occurring 11 months after first alemtuzumab course., Conclusion: We report the third case of autoimmune hemolytic anemia following treatment with alemtuzumab in a young MS patient. Due to the severity of this adverse event, neurologists using this treatment should be alert.
