Abstract
INTRODUCTION Idiopathic Multicentric Castleman Disease (iMCD) is a complex and poorly understood pathophysiological entity, which encompasses a variety of conditions and can mimic or be associated with autoimmune/autoinflammatory diseases, making it challenging to diagnose and treat. Vacuoles, Enzyme E1, X-linked, Autoinflammatory, Somatic (VEXAS) syndrome is an adult-onset autoinflammatory disorder associated with hematological abnormalities and caused by acquired somatic mutations in the ubiquitin-like modifier activating enzyme 1 gene (UBA1) which shares several common clinical and biological signs with iMCD. In this article, we report a patient with VEXAS syndrome initially presenting as iMCD, questioning the link between these two entities. CASE DESCRIPTION We report here a patient initially presenting as iMCD, proved on lymph node histology, which turns out to have a mutation at the splice acceptor site of exon 3 of UBA1 exhibiting VEXAS syndrome with Castleman-like lymph node. CONCLUSION This is only the second case of VEXAS syndrome presenting as iMCD. VEXAS syndrome should therefore be considered in the presence of iMCD suspicion, including in cases of compatible histology.

Abstract
OBJECTIVES To analyse in routine practice the efficacy of targeted therapies on joint involvement of patients with rheumatoid arthritis/systemic sclerosis (RA/SSc) overlap syndrome. METHODS This was a retrospective analysis of medical records of two academic centres over a 10-year period. Joint response to targeted therapies was measured according to EULAR criteria based on Disease Activity Score (DAS)-28. In addition, changes in CRP level and glucocorticoid consumption were recorded. RESULTS Nineteen patients were included. Methotrexate (n=11) and hydroxychloroquine (n=4) were the most used first-line treatments. Targeted therapies were frequently used (n=14). Tocilizumab was the most selected therapy (n=8), then rituximab (n=5), abatacept and anti-tumour necrosis factor (n=4). Twenty-one treatment sequences were assessed, including 18 with EULAR response criteria. Responses were "good" or "moderate" in 100% (4/4) of patients treated with abatacept, 80% (4/5) with rituximab, 40% (2/5) with tocilizumab, and 25% (1/4) with anti-TNF. T and B lymphocyte-targeted therapies (abatacept, rituximab) resulted more frequently in a "good" or "moderate" response compared to cytokine inhibitors (tocilizumab, etanercept, infliximab) with a significant decrease in DAS-28 at 6 months (-1.75; p=0.016) and a trend to a lower consumption of glucocorticoids. CCONCLUSIONS In patients with RA/SSc overlap syndrome refractory to conventional synthetic-DMARDs, T and B lymphocyte-targeted therapies seem to be a promising therapeutic option to control joint activity.

Abstract
Introduction This study aimed to provide an updated analysis of the different prognostic trajectories of patients with anti-melanoma differentiation-associated gene 5 (MDA5) antibodies. Methods Among a cohort of 70 patients, baseline characteristics and phenotypes, treatments and outcomes were analyzed. A Cox proportional hazards model was used to identify factors associated with poor outcomes, i.e., death or progressive disease at the last follow-up. Results Among the 70 patients, 45 were women, and 54 were Caucasian. A dermatologic involvement was observed in 58 (83%) patients, including 40 with MDA5 vasculopathy-related skin lesions. Muscular involvement was observed in 39 (56%) patients. Interstitial lung disease (ILD) was observed at baseline in 52 (74%) patients, including 23 (44%) who developed rapidly progressive (RP) ILD. Seven (10%) patients showed thromboembolic complications within the first weeks of diagnosis, and eight (11%) other patients developed a malignancy (4 before the diagnosis of anti-MDA5 disease). Poor outcomes were observed in 28 (40%) patients, including 13 (19%) deaths. Among the 23 patients with RP-ILD, 19 (79%) showed poor outcomes, including 12 (63%) who died. In multivariate analyses, RP-ILD (hazard ratio (HR), 95% CI: 8.24 [3.21-22], p<0.0001), the occurrence of thromboembolic events (HR: 5.22 [1.61-14.77], p=0.008) and the presence of any malignancy (HR: 19.73 [6.67-60], p<0.0001) were the three factors independently associated with poor outcomes. Discussion This new independent cohort confirms the presence of different clinical phenotypes of anti-MDA5 diseases at baseline and the poor prognosis associated with RP-ILD. Thromboembolic events and malignancies were also identified as prognostic factors.

Abstract
Facial and neckline telangiectasias have an underestimated yet important impact on quality of life of patients with systemic scleroderma (SSc). This monocentric, prospective, open-label, intra-patient comparative study was conducted in 21 consecutive patients with SSc. Patients underwent 4 sessions of PDL 8 weeks apart. A final quadruple assessment was performed by several raters 2 months after the last session, based on the following criteria: change in telangiectasia number; subjective improvement score (LINKERT scale); impact on the quality of life (QoL; SKINDEX score); visual analog pain scale; adverse effects (AEs), including treatment discontinuation for PDL-induced purpura and patient satisfaction. The mean telangiectasia number decreased by 5 (32%) at the end of the protocol. Eighteen patients (85.7%) reported an improvement or a strong improvement, versus 73.81% for the expert committee. Immediate session pain (mean = 3.4/10) was slightly less than overall pain (mean = 4.6/10). Ten patients (47%) experienced at least one AE (oozing/crusts, edema, epidermal blistering), including PDL-induced purpura in 3 patients (14%). AEs were mostly transient (<1 week) and mild (CTCAE grade 1). All QoL parameters improved after treatment, and 85% of patients were satisfied.

Abstract
OBJECTIVE Few comparative data exist on early infections secondary to remission-induction therapy (RIT) with rituximab (RTX) versus cyclophosphamide (CYC) in newly diagnosed anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) patients. We compared and analysed the rates and predictors of severe infection in such patients within the first 6 months following RIT. METHOD From the Caen University Hospital databases, we included all consecutive adults newly diagnosed with ANCA-positive granulomatosis with polyangiitis or microscopic polyangiitis between January 2006 and December 2019. We compared rates of survival without severe infection and survival without infections of any severity within 6 months of RIT and used a multivariate Cox analysis to identify predictors of infection. RESULTS We included 145 patients, 27 in the RTX and 118 in the CYC group. Patients in the RTX group more frequently had pneumococcal vaccination (p < 0.01) and creatinine < 150 µmol/L; other characteristics were comparable between the two groups. Overall, 37 severe infections and 65 infections of any severity were recorded. Rates of survival without severe infection were similar in both groups (p = 0.69), but survival without infections of any severity was lower in the RTX group (p = 0.005). In multivariate analysis, risk factors at diagnosis for severe infections included chronic urinary tract disease, dialysis, and absence of trimethoprim-sulfamethoxazole prophylaxis (p < 0.01 each). CONCLUSIONS Within 6 months of RIT, rates of survival without severe infection were similar in newly diagnosed ANCA-positive AAV patients treated with RTX or CYC, but survival rates without infections of any severity appeared to be lower with RTX treatment.

Abstract
BackgroundDevelopment of Tumor Necrosis Factor blockers (TNFb) whose drug class has several mechanistic and pharmacologic sub-classes, have improved the management of autoimmune and inflammatory diseases, including sarcoidosis. With their increasing use, paradoxical reactions are described and one of the most frequent is sarcoidosis. However, the description of TNFb-induced sarcoidosis (TIS) remains poor, because reported in few and only short case-series.ObjectivesWe aimed to better describe the clinical spectrum of TIS, and the differential involvement of TNFb sub-classes.MethodsFrench pharmacovigilance database was used to collect data on TIS, excluding patients with previous idiopathic sarcoidosis. Statistical analyses were performed using the Mann-Whitney test for quantitative data and Fisher test for qualitative data. A p value < 0.05 was considered statistically significant.ResultsData were obtained from 2002 to 2019 for infliximab, adalimumab, golimumab, certolizumab and etanercept. Thirty-one TIS patients were collected from the database, including 12 women (38.7%). In most cases, TNFb was introduced for ankylosing spondylitis (58%), psoriasis (19.3%) or rheumatoid arthritis (16.1%). Median age at TIS occurrence was 54 [43.5; 61.5] years, with a median time to onset of 24 [6.0; 72.0] months. The most frequent involved TNFb was etanercept (n=21, 67.8%). The two mains clinical TIS manifestations were lymph node (n=27, 87.1%) and lung involvement (n=16, 51.6%). The culprit drug was discontinued in 26 (84%) patients, and a double-barreled inflammatory gun to control both initial and induced disorders was proposed in 19 of them (90.5 %), mostly glucocorticoids (n=13, 68.4%) alone or combined with methotrexate (n=3, 15,8%). Among the 14 patients with the available data, the TIS had completely resolved in 11 (78.6%); for all these lasts, the TNFb was discontinued. No significant differences were observed between the TNFb sub-classes of monoclonal antibodies or fusion proteins, regarding clinical presentation, median time to onset or outcome.ConclusionThis second largest case-series shows that TIS are mostly encountered with etanercept, but without any difference in clinical or prognostic implications with the other TNFb-subclasses.References[1]Aggarwal BB, Gupta SC, Kim JH.

Abstract
BackgroundMyeloperoxidase (MPO) plays a major role in loss of immunological tolerance leading to tissue destruction in ANCA-associated vasculitis (AAV). Ceruloplasmin is a protein with antiproteinase and antioxidant properties that inhibits MPO activity. Whether serum level of ceruloplasmin at AAV diagnosis has an impact is unknown.ObjectivesThe objective of this study was to evaluate the prognostic impact of serum level of ceruloplasmin at diagnosis in patients with granulomatosis with polyangiitis or microscopic polyangiitis.MethodsWe conducted a retrospective unicentric study at Caen University Hospital, involving consecutive adult patients with granulomatosis with polyangiitis or microscopic polyangiitis between 2010 and 2021 who had available serum at diagnosis. Data was collected using the health records.Ceruloplasmin was measured by standardized nephelometry (normal values: 0.15 – 0.50 g/L). Patients in each subgroup (whole cohort, microscopic polyangiitis and anti-MPO patients) were divided into two groups based on the median serum level of ceruloplasmin.We estimated survival using the Kaplan-Meier survival curve, and between-group differences were evaluated by the log-rank test. The study was approved by the local ethics committee of Caen University Hospital (n° 1947).ResultsNinety-two patients were included, 46 (50%) granulomatosis with polyangiitis (41 anti-proteinase 3 and 5 anti-MPO) and 46 (50%) microscopic polyangiitis (45 anti-MPO and 1 anti-proteinase 3). The median level of ceruloplasmin was 0.44 g/L. No significant differences in the clinical presentation were observed between patients in the two groups (p>0.05). We observed 9 (19.6%) deaths in the low ceruloplasmin group and 5 (10.9%) in the high ceruloplasmin group (p=0.39). Vasculitis relapse occurred in 10/46 patients (22%) and 11/46 patients (24%) (p=1), renal failure leading to dialysis and/or renal transplant in 6/46 patients (13%) and 8/46 patients (17%) (p=0.77), respectively. No significant difference in survival was found (p=0.07). The same analyses were performed between the low and the high ceruloplasmin group with the microscopic polyangiitis subgroup (n=46), and no significant differences were found (p>0.05). However, within the anti-MPO subgroup (n=50), the survival was worse in the low ceruloplasmin group (p=0.03).ConclusionIn anti-MPO AAV patients, serum level of ceruloplasmin at diagnosis seems to be associated with a significant impact on survival.References[1]Baskin E, et al.

Abstract
BACKGROUND Necrozoospermia is a condition found in 0.2 to 0.4 % of male infertility cases. The causes of necrozoospermia are multiple: they can be related to testicular and/or post-testicular damage. Additionally, these causes most often involve the production of reactive oxygen species (ROS) and/or sperm DNA fragmentation (SDF) which can reduce the chances of spontaneous pregnancy or affect the outcome of assisted reproductive technologies. OBJECTIVE To focus on potential etiologies of necrozoospermia, its diagnosis and its therapeutic management especially before the employment of ICSI. METHODS Authors searched PubMed/Medline, Web of Science, Cochrane Library, Google and Institutional websites for medical subheading terms and free text words referred to "necrozoospermia", "sperm vitality", "sperm viability", "sperm DNA fragmentation" and "ICSI". RESULTS We identified twelve main etiologies of necrozoospermia responsible for either a decrease of sperm vitality, a mild a moderate or a severe necrozoospermia. In case of a confirmed decreased vitality, a thorough check-up should be conducted and if available, etiological treatment should be proposed. Therapeutic management could also include repeated ejaculations, drug treatments, the use of ICSI with ejaculated or surgically extracted spermatozoa in case of a non-treatable necrozoospermia. DISCUSSION AND CONCLUSION The potential causes of necrozoospermia should be investigated because many of them could be corrected, thus avoiding the use of ICSI. Moreover, if ICSI procedure remains necessary, the therapeutic management of necrozoospermia could also improve the chances of success by reducing oxidative stress and/or sperm DNA fragmentation.

Abstract
BACKGROUND & AIMS Secondary to tumour necrosis factor-alpha induced protein 3 (TNFAIP3) mutations, A20 haploinsufficiency (HA20) is a recently described autoinflammatory disease with clinical features similar to those of Behçet's and Crohn's diseases but with a constantly expanding clinical spectrum. Here, we describe HA20 liver involvement in three new patients from the same family. METHODS We retrospectively assessed clinical, biological and/or histological findings for eight patients over three generations of the same family with heterozygous mutations in the TNFAIP3 gene (c.259C > T, p.Arg87*). RESULTS The eight patients exhibited the following: aphthous ulcers (8/8, bipolar in 7), autoimmune features (6/8, including 5 with definitive autoimmune disease diagnoses, ie, type I diabetes, Hashimoto thyroiditis, pernicious anaemia, and/or 5 with antinuclear antibodies ≥320), pustulosis/folliculitis (5/8), abdominal pain (4/8), arthralgia (3/8), enlarged cervical lymph nodes (3/8) and pericarditis (1/8). In addition, three patients (twin sisters and their grandmother aged 23 and 70 years, respectively) exhibited persistent mild hepatic cytolysis associated with splenomegaly (n = 3), hepatomegaly (n = 1) and/or liver atrophy (n = 1) on echography. We could not detect any other causes of chronic liver diseases. Liver biopsies from three patients displayed hepatic fibrosis, hepatocyte injury and/or CD4+ /CD8+ T lymphocyte infiltration, and patterns of inflammatory cells and NLRP3 or NF-κB immunostaining differed from the predominant neutrophil infiltration observed in skin or some digestive tract biopsies. CONCLUSIONS This study reinforces the dual involvement of innate and adaptive immunity in HA20 according to both acute and chronic injury and the organ involved and widens its clinical spectrum to include chronic hepatic involvement.

Abstract
OBJECTIVE The literature data supporting the role of a drug in the onset of drug-associated anti-neutrophil cytoplasmic antibody-associated vasculitis (DA-AAV) mainly rely on case reports or short series and implicate old treatments. The advent of new treatments may have modified the epidemiology of these adverse drug reactions (ADRs). We therefore aimed to update this list by using a pharmacovigilance-based data mining approach. METHODS We collected data on ADRs reported with the MedDRA preferred term "Anti-neutrophil cytoplasmic antibody positive vasculitis" up to November 2020 from the World Health Organization pharmacovigilance database (VigiBase® ). For each retrieved drug, a case/noncase analysis was performed, and disproportionate reporting was calculated by using the information component (IC). A positive IC025 value, which is the lower end of the 95% credibility interval, was considered significant. RESULTS A total of 483 deduplicated individual case safety reports of DA-AAV involving 15 drugs with an IC025 >0 were retrieved. DA-AAV occurred in 264 (71.2%, n=371) women, the median age at onset was 62 years [45-72], and the median time to onset between the introduction of the suspected drug and DA-AAV was 9 months [1-36]. DA-AAV occurrence was considered serious in 472 (97.7%, n=481) cases and fatal in 43 (8.9%) cases. The drugs associated with the highest disproportionate reporting were hydralazine, propylthiouracil, thiamazole, sofosbuvir, minocycline, carbimazole, mirabegron, and nintedanib. CONCLUSION This study strengthens the previously suspected association but also identifies 3 new drugs that may cause DA-AAV. Particular attention should be given to these drugs by prescribers and in experimental studies.

Abstract
Background:Several pharmacological classes are involved in drug-associated anti-neutrophil cytoplasmic antibody-associated vasculitis (DA-AAV). However, the literature data supporting the role a drug in the onset of DA-AAVs mainly rely on case reports or short series and implicate old treatments. Moreover, the advent of new treatments, including targeted therapies, may have modified the epidemiology of these adverse drug reactions (ADRs).Objectives:To update this list by using a pharmacovigilance-based data mining approach.Methods:We collected data on ADRs reported with the MedDRA preferred term “Anti-neutrophil cytoplasmic antibody positive vasculitis” up to November 2020, from the World Health Organization pharmacovigilance database. For each retrieved drug, a case/noncase analysis was performed, and disproportionate reporting was calculated by using the information component (IC). A positive IC025 value, which is the lower end of the 95% credibility interval, was considered significant.Results:A total of 483 deduplicated individual case safety reports of DA-AAV involving 15 drugs with an IC025>0 were retrieved. DA-AAV occurred in 264 (71.2%, n=371) women, the median age at onset was 62 years [45-72], and the median time to onset between the introduction of the suspected drug and DA-AAV was 9 months [1-36]. DA-AAV occurrence was considered serious in 472 (97.7%, n=481) cases and fatal in 43 (8.9%) cases. The drugs associated with the highest disproportionate reporting were hydralazine, propylthiouracil, thiamazole, sofosbuvir, minocycline, carbimazole, mirabegron, and nintedanib (Table 1).Table 1.List of the 15 drugs associated with ANCA-associated vasculitis in the World Health Organization pharmacovigilance database with significant disproportional reporting, sorted by decreasing IC025.DrugNobservedNfatal (%)IC025 / ICROR [95%CI]Delay (in days) between the introduction of the drug and AAV, median [Q1-Q3] (n available)Hydralazine20819 (9%)8.2 / 8.42683.5 [2269.3-3173.3]1277 (n=1)Propylthiouracil1084 (4%)7.2 / 7.51201.5 [974.8-1480.9]1003 [425-1959] (n=19)Thiamazole405 (13%)5.2 / 5.6138.7 [100.7-191.1]411 [58-966] (n=6)Sofosbuvir4604.9 / 5.374.6 [55.3-100.8](n=0)Minocycline1703.8 / 4.672.4 [44.7-117.3](n=0)Carbimazole602.0 / 3.444.9 [20.1-100.4]92 (n=1)Mirabegron72 (29%)1.5 / 2.711.1 [5.3-23.3]291 [289-415] (n=3)Nintedanib62 (33%)1.4 / 2.814.2 [6.3-31.7]56 [36-132] (n=4)Penicillamine41 (25%)1.4 / 3.1170.3 [63.5-456.3](n=0)Influenza vaccine292 (7%)1.3 / 1.94.1 [2.8-6.0]24 [20-26] (n=7)Allopurinol72 (29%)1.2 / 2.48.0 [3.8-16.8](n=0)Rifampicin72 (29%)0.6 / 1.94.7 [2.2-9.8](n=0)Peginterferon alfa-2b400.3 / 2.17.0 [2.6-18.6]98 (n=1)Montelukast44 (100%)0.2 / 1.95.8 [2.2-15.5](n=0)Rosuvastatin600.1 / 1.53.4 [1.5-7.5](n=0)IC: information component; ROR: reporting odds ratio; CI: confidence interval; AAV: ANCA-associated vasculitisConclusion:This study strengthens the previously suspected association but also identifies 3 new drugs that may cause DA-AAV.

Abstract
Background:Few comparative data exist on early infections secondary to remission-induction therapy (RIT) with rituximab versus cyclophosphamide in newly-diagnosed ANCA-associated vasculitis (AAV) patients.Objectives:We compared and analyzed the rate and predictors of severe infections in such patients within the first six months following RIT.Methods:We included, from the databases of Caen University Hospital, all consecutive adults newly-diagnosed with granulomatosis with polyangiitis or microscopic polyangiitis between January 2006 and December 2019. We compared the survival without severe infections (WSI) and the survival without infection of any severity (WIOAS) within 6 months from the RIT, and used a multivariate cox analysis to identify predictors of infection.Results:We included 145 patients, 27 in rituximab group and 118 in cyclophosphamide group. Patients in the rituximab group more frequently had pneumococcal vaccination (p<0.01) and creatinine level <150 µmol/L, while other characteristics, including Birmingham Vasculitis Activity Score, were comparable between both groups.Overall, 37 severe infections and 65 infections of any severity were recorded. The survival WSI was similar in both groups (p=0.69), but survival WIOAS was lower in rituximab group (p=0.005).In multivariate analysis, risk factors at diagnosis for severe infections were chronic urinary tract disease, dialysis and absence of prophylaxis with trimethoprim-sulfamethoxazole (p<0.01 each).Conclusion:The survival WIS within the 6 months following RIT was similar in patients with newly-diagnosed AAV treated by rituximab or cyclophosphamide, but survival WIOAS appeared to be lower within the 6 months following rituximab despite a better pneumococcal vaccination coverage.Figure 1.Comparison of the 6-month survival without severe infection (A) or without infection of any severity (B) in patients with newly-diagnosed ANCA-associated vasculitis treated by rituximab or cyclophosphamideDisclosure of Interests:None declared

Abstract
INTRODUCTION Pyoderma gangrenosum (PG) is a rare, mainly dermatological condition, whose unusual and little-known lung involvement presents a diagnostic and therapeutic challenge. CASE REPORT A 66-year-old man, followed for 6 years for an IgA monoclonal gammopathy of undetermined significance and an initially cutaneous corticosteroid-dependent PG, received a pneumonectomy for a mass suspected of neoplasia, that turns out to be a PG pulmonary localisation. During successive pneumopathies, sometimes dyspneic and excavated, several hypotheses are discussed. Various infectious and immunological explorations, and various antibacterial/fungal or immunosuppressive therapies are conducted, to finally conclude to pulmonary and/or cutaneous recurrences of PG. The outcome at 14 months seems finally favourable with tofacitinib. CONCLUSION The recognition of cutaneous involvement of PG, which is essential for the diagnosis of its lung involvement, is probably the mirror of its evolution under treatment. Only multidisciplinary confrontation of reported cases will allow the elaboration of diagnostic and therapeutic recommendations.

Abstract
BACKGROUND For the past decades, number of prophylactic bilateral mastectomies using reconstruction with implants increases. We describe a new surgical strategy and analyse its safety and feasability. METHOD It is a retrospective, descriptive and monocentric study. The first step of surgery consisted in obteining a peri-prosthetic capsule with implants and if there was a mammary hypertrophy and/or ptosis, it was corrected at the same time. The second step of surgery was the nipple-sparing mastectomy with change of implants for bigger ones. Third step consisted in a lipofilling. RESULTS Seven patients were included. 6 women had a BRCA1 gene mutation. Mean age was 35.6 year-old [29.6; 41.6], mean BMI was 23.8kg/m2 [20.6; 27], mean chest circumference was 93.7cm [87.4; 100], mean cup was C- [B-; D-]. 4 women had mammary hypertrophy and/or ptosis. Mean number of procedure per woman was 3.6 [2.5; 4.7]. Mean volume of implants used at the first step was 248.6ml [211.3; 285.9]. The second step was performed mean 33.9 weeks [22.3; 45.5] later. Mean increase of implants volume was 120ml [80.4; 159.6]. 4 patients had complications including 1 who had implant exposure. Six patients had lipofilling of mean volume per breast of 175ml [116; 234]. CONCLUSION This new strategy could decrease complication rate, improve aesthetic outcome and decrease psychological impact of surgery.

Abstract
Background:Protease-activated receptor-2 (PAR2) is a member of a family of G-protein-coupled receptors involved in multiple physiological mechanisms. Compelling evidences have unravelled the key roles of PAR2 in the pathology of both rheumatoid arthritis (RA) and osteoarthritis (OA)1. Indeed, in vitro, in vivo and ex vivo experiments showed that this receptor promotes inflammation, cartilage erosion (and subsequent bone degradation), and pain. However, the signalling pathways involved in these functions are not well understood2. This is of importance as some pathways can promote the pathogenesis3while others prevent it4. We developed a new series of small molecules as novel biased PAR2 inhibitors to treat rheumatic diseases.Objectives:To evaluate the efficacy and mechanism of action of new biased PAR2 inhibitors on cartilage erosion and inflammation.Methods:The potency of compounds to inhibit human PAR2 signalling was evaluated in vitro by FLIPR calcium assay in HEK293 cells. The same assay was used to determine their selectivity over human PAR1 and PAR4 as well as murine versions of PAR2. The effect of several PAR2 inhibitors on 9 signalling pathways (Gi2, GoB, Gz, Gq, G13, G14, G15, B arrestin 2, EPAC) was evaluated by the BRET-based bioSens-All™ technology. In vitro anti-hypertrophic effect was determined by measuring the mRNA level of type II collagen, aggrecan and MMP13 in rat chondrocytes after IL1β stimulation. In vitro anti-inflammatory effect was determined by measuring the secretion of IL6, IL8, IL1β, TNFα and IFNγ by human monocytes. In vivo, the pharmacodynamic of our small molecules was assessed after intravenous and oral administration. Therapeutic efficacy of a compound was then evaluated in a collagen-induced arthritis model in DBA1/J mice. In this model, measures of the arthritis index score, body weight, plasma level of TNFα, IL6, IL8 and IL1β and histological evaluation of cartilage erosion were performed.Results:Our new series of small molecules are potent PAR2 inhibitors (IC50<1nM in calcium assay) with some selectivity over PAR1 and PAR4. Our compounds significantly inhibited PAR2 mediated recruitment of Gz, Gq, G13, G14 and G15. However, surprisingly, these small molecules had no effect on B arrestin 2, EPAC, Gi2 and GoB demonstrating that they are biased inhibitors. The effect of our compounds on PAR2 signalling was clearly different from 3 already existing PAR2 inhibitors described in the literature (I-117, AZ3451 and P2pal-18s). We compared the in vitro anti-hypertrophic effect on chondrocyte and anti-inflammatory effect on monocytes of these compounds to determine the importance of PAR2 signalling pathways in these cellular functions. In vivo, our small molecules had good bioavailability after oral administration of 10mg/kg in mice (clearance = 0.038L/h/kg; T½ = 9.9h; AUC= 162564 ng.h/mL; Cmax = 9005 ng/mL). The in vivo therapeutic efficacy of a biased PAR2 inhibitor in a model of collagen-induced arthritis will be presented.Conclusion:Our results show the potency of biased PAR2 inhibitors to reduce both the inflammation and cartilage erosion in rheumatoid arthritis. They confirm the huge potential of PAR2 as a therapeutic target and unravel the relevance of biased antagonism of this receptor to treat rheumatic diseases.References:[1]McCulloch et al., Frontiers in Endocrinology, 2018;2Hollenberg et al., British Journal of Pharmacology, 2014;3Sharma et al., Genes and Immunity, 2015;4Rayees et al., Cell Reports, 2019Disclosure of Interests:Thibaut Brugat Employee of: Domain Therapeutics, Baptiste Rugeri Employee of: Domain Therapeutics, Gaël Hommet Employee of: Domain Therapeutics, Alexia Dumont Employee of: Domain Therapeutics, Luc Baron Employee of: Domain Therapeutics, Célia Halter Employee of: Domain Therapeutics, Meriem Sémache Employee of: Domain Therapeutics, Arturo Mancini Employee of: Domain Therapeutics, Camille Amalric Employee of: Domain Therapeutics, Marie Giambelluco Employee of: Domain Therapeutics, Nathalie Lenne Employee of: Domain Therapeutics, Marjorie Sidhoum Employee of: Domain Therapeutics, Christel Franchet Employee of: Domain Therapeutics, Stanislas Mayer Employee of: Domain Therapeutics, Xavier Leroy Employee of: Domain Therapeutics, Stephan Schann Employee of: Domain Therapeutics

Abstract
AbstractBackgroundThe death rate due to suicide in elderly people is particularly high. As part of suicide selective prevention measures for at-risk populations, the WHO recommends training “gatekeepers”.MethodsIn order to assess the impact of gatekeeper training for members of staff, we carried out a controlled quasi-experimental study over the course of one year, comparing 12 nursing homes where at least 30% of the staff had undergone gatekeeper training with 12 nursing homes without trained staff. We collected data about the residents considered to be suicidal, their management further to being identified, as well as measures taken at nursing home level to prevent suicide.ResultsThe two nursing home groups did not present significantly different characteristics. In the nursing homes with trained staff, the staff were deemed to be better prepared to approach suicidal individuals. The detection of suicidal residents relied more on the whole staff and less on the psychologist alone when compared to nursing homes without trained staff. A significantly larger number of measures were taken to manage suicidal residents in the trained nursing homes. Suicidal residents were more frequently referred to the psychologist. Trained nursing homes put in place significantly more suicide prevention measures at an institutional level.ConclusionsHaving trained gatekeepers has an impact not only for the trained individuals but also for the whole institution where they work, both in terms of managing suicidal residents and routine suicide prevention measures.

Abstract
Double-positive vasculitis with anti-polynuclear cytoplasm (ANCA) and anti-glomerular basement membrane (GBM) antibodies is a rare entity of systemic vasculitis defined by the presence of ANCA and anti-GBM antibodies. The gradual accumulation of clinical and therapeutic data shows the usefulness of identifying and differentiating this entity from the two vasculitis respectively associated with the isolated presence of each of these two antibodies. Indeed, the double-positive ANCA and anti-GBM vasculitis appears to associate the characteristics of the demography and the extra-renal and pulmonary involvement of the ANCA-associated vasculitis on the one hand, and of the histological type and severe renal prognosis of the anti-MBG vasculitis on the other hand, with the renal involvement which is the only involvement consistently observed in double-positive vasculitis. The aim of this focus is to describe the epidemiological, clinico-biological, histological and prognostic characteristics of this entity, in light of recent literature and ongoing therapeutic changes in the two eponymous vasculitis.

Abstract
Abstract
Background
With 50,000 death every year, cervical cancer is the fourth most common cause of death by cancer in sub-Saharan countries. Due to high risk human papilloma virus (hr-HPV) persistence on the cervix, leading to pre-malignous lesions, the disease is more frequent among HIV-positive women. In low- and middle-income countries, cervical cancer screening strategy relies on visual inspection with acetic acid, an operator-associated technic. As an alternative, HPV-based detection and its better performances are considered as it could lead to a potential screening uptake and women empowerment through self-sampling. Côte d’Ivoire, with a high HIV prevalence, is considering this innovative strategy. Yet, few studies analyzed the potential socio-cultural factors associated with cervical cancer screening in this context. Our study aims to assess beliefs and perceptions toward cervical cancer among HIV positive women in Abidjan, Côte d’Ivoire.
Methods
We performed in-depth interviews with 21 HIV positive women randomly attending a health center or member of a women’s association, in November 2018. All interviews were recorded and transcribed. A theoretical framework with the Health Belief Model and the PEN-3 was used to categorize women’s perceptions, enablers, nurturers, perceived gravity and self-efficacy about cervical cancer, screening and self-sampling technique introduction.
Results
Positive findings were knowledge about cervical cancer, awareness about women’s vulnerability and HIV status role on it and relationship to caregivers. Fear appeared as a barrier to screening but also a facilitator among women with health awareness. Negative findings were reluctance for HIV-associated diseases, poor screening knowledge and lack of resources to get treated. Self-sampling introduction was disregarded due to lack of self-confidence.
Conclusions
This study provides useful information for counselling and opens the door to HPV-based screening implementation.
Key messages
Beliefs and perceptions about cervical cancer screening among HIV women need to be assess before implementing a new strategy. Cervical cancer screening uptake will need to address fear, self-confidence and stigma.

Abstract
INTRODUCTION Some studies suggest that there is an increased risk of malignancies in giant cell arteritis (GCA). We aimed to describe the clinical characteristics and outcomes of GCA patients with concomitant malignancy and compare them to a GCA control group. METHOD Patients with a diagnosis of GCA and malignancy and with a maximal delay of 12 months between both diagnoses were retrospectively included in this study and compared to a control group of age-matched (3:1) patients from a multicenter cohort of GCA patients. RESULTS Forty-nine observations were collected (median age 76 years). Malignancies comprised 33 (67%) solid neoplasms and 16 (33%) clonal hematologic disorders. No over-representation of a particular type of malignancy was observed. Diagnosis of GCA and malignancy was synchronous in 7 (14%) patients, while malignancy succeeded GCA in 29 (59%) patients. Malignancy was fortuitously diagnosed based on abnormalities observed in laboratory tests in 26 patients, based on imaging in 14 patients, and based on symptoms or clinical examination in the nine remaining patients. Two patients had a concomitant relapse of both conditions. When compared to the control group, patients with concomitant GCA and malignancy were more frequently male (p < 0.001), with an altered general state (p < 0.001), and polymyalgia rheumatica (p < 0.01). CONCLUSIONS This study does not indicate an over-representation of any particular type of malignancy in GCA patients. Initial follow-up dictated by vasculitis may have led to an early identification of malignancy. Nevertheless, GCA male patients with an altered general state and polymyalgia rheumatica might more frequently show concomitant malignancies.

BACKGROUND Maternal virilization during pregnancy is a rare phenomenon. Polycystic ovary syndrome (PCOS), luteoma and luteinic cysts are the most frequent and benign etiologies. This article presents two cases of recurrent maternal virilization during pregnancy. CLINICAL CASES Our reported cases were young women with Afro-Caribbean and Nigerian origins. Data were collected by history-taking, clinical examination, laboratory investigations, transabdominal ultrasonographic examination and Magnetic Resonance Imaging. Both patients were diagnosed with PCOS according to the Rotterdam criteria. During each of their pregnancies they both developed an explosive hirsutism, a deepening in the voice, a clitoromegaly. Gestational diabetes occurred during pregnancies. There was no fetal virilization, despite raising androgen levels, more than tenfold to normal. Improvement of hirsutism and normalization of androgens were described in postpartum. CONCLUSION Only few cases of maternal virilization during pregnancy were reported in literature and even fewer concern recurrent and bilateral ovarian etiology. Hyperplasia of ovarian theca cells seems to be the most likely explanation, which would suggest that PCOS belongs to a spectrum of abnormal reactivity of the ovary to human Chorionic Gonadotrophin (hCG) stimulation along with luteoma and luteinic cyst of pregnancy. Insulin resistance could worsen hyperandrogenism but is not enough to explain virilization. Treatment should focus on protecting the fetus of possible virilization as well as its mother, but also on preserving the subsequent fertility in both.

Abstract
The presence of neighbouring plants and predation risk can affect trophic interactions between plants and herbivores. We hypothesized that the relative preference for neighbouring species would determine winter herbivory and that predation risk would modulate browsing pressure. We tested these hypotheses using feeding trials in two regions with high white-tailed deer (Odocoileus virginianus (Zimmermann, 1780)) densities: Outaouais and Anticosti Island (Quebec, Canada). In each, we selected a species of interest and compared browsing rates and time spent foraging with neighbours relatively preferred or avoided. In a subexperiment, we included coyote (Canis latrans Say, 1823) urine to test for threat-sensitive foraging and interactions with neighbour effects. In Outaouais, time spent foraging on the focal species was reduced by the presence of potentially avoided neighbours and deer reduced browsing with increased perceived predation risk. On Anticosti, browsing rates on the focal species increased with avoided neighbours, with no effect of the predator urine. Anticosti deer have been in a predator-free environment for more than 120 years, likely reducing antipredator behaviours. This study demonstrates both neighbour effects and threat-sensitive foraging, phenomena that could interact and thus would benefit from being studied together to better represent trophic interactions in natural environments.

Could myo-inositol soft gel capsules outperform clomiphene in inducing ovulation? Results of a pilot study. EUROPEAN REVIEW FOR MEDICAL AND PHARMACOLOGICAL SCIENCES 2017; 21:10-14.

Abstract
OBJECTIVE Insulin resistance is known to worsen polycystic ovarian syndrome (PCOS). The management of insulin resistance is crucial in the treatment of PCOS and insulin-sensitizing molecule as myo-inositol (MYO) seems to have promising effects. The aim of our pilot study was to study whether supplementation with MYO can improve patients' sensitivity to clomiphene citrate (CC) in terms of ovulation and pregnancy rates. PATIENTS AND METHODS This study included 26 patients with PCOS, eligible to ovulation induction with CC. All of them received MYO in combination with CC and folic acid, following the usual protocol. Results concerning ovulation and pregnancy rates were compared to those from our historical cohort of PCOS patients treated with CC alone. RESULTS Ovulation rate was significantly higher with MYO+CC than with CC alone (65.5% vs. 42%, p=0.0001). The number of patients sensitive to 50 mg/d was 54% with MYO vs. 40% in our reference cohort (NS). The total resistance rate was 19% vs. 27% in the reference cohort (NS). Cumulative pregnancy rate with MYO+CC was 53.8% vs. 42.2% with CC alone (NS). Pregnancy rates per initiated cycle were 16.1% with MYO vs. 12.6% in the historical cohort (NS). DISCUSSION Although the differences were not significant for most outcomes, probably due to the small number of patients, our pilot study seemed to show a benefit of supplementation with MYO during ovulation induction with CC in PCOS patients. CONCLUSIONS This study proves the great interest of a RCT and re-opens the possibilities of insulin-sensitizing agents in the treatment of anovulatory patients with PCOS, such as natural products like MYO.

Boosting syntax training with temporally regular musical primes in children with cochlear implants. Ann Phys Rehabil Med 2017; 61:365-371.

Abstract
OBJECTIVES Previous research has suggested the use of rhythmic structures (implemented in musical material) to improve linguistic structure processing (i.e., syntax processing), in particular for populations showing deficits in syntax and temporal processing (e.g., children with developmental language disorders). The present study proposes a long-term training program to improve syntax processing in children with cochlear implants, a population showing syntax processing deficits in perception and production. METHODS The training program consisted of morphosyntactic training exercises (based on speech processing) that were primed by musical regular primes (8 sessions) or neutral baseline primes (environmental sounds) (8 sessions). A crossover design was used to train 10 deaf children with cochlear implants. Performance in grammatical processing, non-word repetition, attention and memory was assessed before and after training. RESULTS Training increased performance for syntax comprehension after both prime types but for grammaticality judgements and non-word repetition only when musical primes were used during training. For the far-transfer tests, some effects were also observed for attention tasks, especially if fast and precise sequential analysis (sequencing) was required, but not for memory tasks. CONCLUSIONS The findings extend the previously observed beneficial short-term effects of regular musical primes in the laboratory to long-term training effects. Results suggest that the musical primes improved the processing of the syntactic training material, thus enhancing the training effects on grammatical processing as well as phonological processing and sequencing of speech signals. The findings can be interpreted within the dynamic attending theory (postulating the modulation of attention over time) and associated oscillatory brain activity. Furthermore, the findings encourage the use of rhythmic structures (even in non-verbal materials) in language training programs and outline perspectives for rehabilitation.
