A patient was diagnosed with discitis and sacroiliitis due to Mycobacterium xenopi. He had a history of percutaneous nucleotomy performed 15 years earlier (in 1992) at the Clinique du Sport, Paris, France, during an outbreak of nosocomial M. xenopi infection at that institution. In 1997, magnetic resonance imaging performed as part of the routine follow-up program for patients who had surgery at the Clinique du Sport during the outbreak was not interpreted as indicating discitis; this assessment was confirmed by our review of the images. Bone and joint infections due to atypical mycobacteria are rare and can develop very slowly. To our knowledge, this is the first reported case of M. xenopi discitis with secondary extension to the sacroiliac joint in an immunocompetent patient. [ABSTRACT FROM AUTHOR]

We conducted a national in-depth analysis including pharmacovigilance reports and clinical study to assess the reporting rate (RR) and to determine the clinical profile of polymyalgia rheumatica (PMR) and giant cell arteritis (GCA) in COVID-19-vaccinated individuals. First, based on the French pharmacovigilance database, we estimated the RR of PMR and GCA cases in individuals aged over 50 who developed their initial symptoms within one month of receiving the BNT162b2 mRNA, mRNA-1273, ChAdOx1 nCoV-19, and Ad26.COV2.S vaccines. We then conducted a nationwide survey to gather clinical profiles, therapeutic management, and follow-up data from individuals registered in the pharmacovigilance study. A total of 70 854 684 COVID-19 vaccine doses were administered to 25 260 485 adults, among which, 179 cases of PMR (RR 7. 1 cases/1 000 000 persons) and 54 cases of GCA (RR 2. 1 cases/1 000 000 persons) have been reported. The nationwide survey allowed the characterization of 60 PMR and 35 GCA cases. Median time to the onset of first symptoms was 10 (range 2-30) and 7 (range 2-25) days for PMR and GCA, respectively. Phenotype, GCA-related ischemic complications and -large vessel vasculitis as well as therapeutic management and follow-up seemed similar according to the number of vaccine shots received and when compared to the literature data of unvaccinated population. Although rare, the short time between immunization and the onset of first symptoms of PMR and GCA suggests a temporal association. Physician should be aware of this potential vaccine-related phenomenon.

The French Society of Rheumatology recommendations for managing rheumatoid arthritis (RA) has been updated by a working group of 21 rheumatology experts, 4 young rheumatologists and 2 patient association representatives on the basis of the 2023 version of the European Alliance of Associations for Rheumatology (EULAR) recommendations and systematic literature reviews. Two additional topics were addressed: people at risk of RA development and RA-related interstitial lung disease (RA-ILD). Four general principles and 19 recommendations were issued. The general principles emphasize the importance of a shared decision between the rheumatologist and patient and the need for comprehensive management, both drug and non-drug, for people with RA or at risk of RA development. In terms of diagnosis, the recommendations stress the importance of clinical arthritis and in its absence, the risk factors for progression to RA. In terms of treatment, the recommendations incorporate recent data on the cardiovascular and neoplastic risk profile of Janus kinase inhibitors. With regard to RA-ILD, the recommendations highlight the importance of clinical screening and the need for high-resolution CT scan in the presence of pulmonary symptoms. RA-ILD management requires collaboration between rheumatologists and pulmonologists. The treatment strategy is based on controlling disease activity with methotrexate or targeted therapies (mainly abatacept or rituximab). The prescription for anti-fibrotic treatment should be discussed with a pulmonologist with expertise in RA-ILD., (Copyright © 2024 The Authors. Published by Elsevier Masson SAS..

Background: Uncontrolled gout can cause articular impairment but is also associated with a global and cardiovascular excess mortality, especially in dialysis population. Data documented within existing research is not conclusive regarding gout flares evolution during hemodialysis and their control by urate lowering therapy (ULT). Without clear guidelines concerning hemodialysis patients management with chronic gout, this study proposes to investigate whether gout flare incidence reduction could be observed on this population treated by urate lowering therapy versus patients without treatment., Methods: We performed a retrospective cohort study in two hemodialysis centers in France. Were selected patients over 18 years old with a gout history who started hemodialysis between January 2005 and September 2015. Demographics and clinicals data were recorded at hemodialysis start and throughout 5 years of follow up. Gout flare was defined as presence of uric acid crystal in joint punction or clinically diagnosed as such with a colchicine prescription. All statistical analysis were performed in SAS® version 9.4 (SAS Institute Inc., Cary, NC)., Results: One hundred eighty-one patients have been included, mean age at dialysis initiation was 68.6 years (± 12.4) with 72% of men, 54% were treated by ULT: 89.7% by allopurinol and 9.3% by febuxostat. One patient received both treatments successively. After hemodialysis initiation, 35.36% patients had experienced at least one gout flare. The appearance of at least one gout flare concerned 50% of patients in no ULT group and 22.68% patients in ULT group (p = 0.0002). Dialysis efficiency was measured at regular interval during follow-up and was similar in both groups. To study the association strength between clinical factors and gout flares occurrences, a Cox model was performed; ULT is a protector factor of gout flare (HR:0,42, CI 95: 0,25-0,71). The proportion of serum urate values within the target (median 53% vs 29.3%, p < 0.0001) was significantly higher in ULT group versus no ULT group (median 53% vs 29.3%, p < 0.0001)., Conclusion: Urate lowering therapy limit new gout flares occurrence in hemodialysis patients with gout historyCollaboration between rheumatologists and nephrologists may help to update guidelines for urate-lowering therapies in patients on dialysis., (© 2024.

Objectives: Non-adherence to rheumatoid arthritis (RA) treatments must be identified. A methotrexate (MTX) urinary dosage (METU) was recently developed. The aim of our study was to assess adherence to MTX in RA using METU in real-life conditions and to compare it with indirect adherence measurement technics., Methods: We performed a cross-sectional study at Reims University Hospital. We included over 18-year-old patients with RA treated by MTX for more than 6 months. Patients were invited to complete demographic, clinical and psychological questionnaires and adherence measurement technics (Compliance Questionnaire of Rheumatology (CQR) and Medication Possession Ratio (MPR)). A urinary sample was collected to measure MTX and information about tolerance was evaluated through Methotrexate Intolerance Severity Score., Results: 84 patients were included, 26 using oral MTX, 58 subcutaneous (SC) MTX. Among them, 73% were female, mean age was 61.5 years, MTX mean dose was 15 mg/week and 61.9% were treated by biological DMARDs (Disease Modifying Antirheumatic Drugs). 77 patients (91.7%) were adherent to treatment according to METU, whereas MPR and CQR reported less adherence (69.5% and 61.9%, respectively). MPR and METU were not significantly different in SC MTX users (p=0.059). Non-adherent patients had a higher number of tender joints and C reactive protein value (p<0.05)., Conclusion: This is the first largest study evaluating MTX adherence in patients with RA using a urinary dosage. We identified that indirect adherence measurements did not reflect real-life adherence. It would be appreciable to realise METU, in a new study, in patients with RA with unexplained response to treatment, to consider it before escalating therapeutic strategy., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: The least significant change (LSC) threshold of 0.03 g/cm² is used to interpret bone mineral density (BMD) scans in the general population. Our working hypothesis was that the current LSC threshold would not be applicable in obese populations., Aims: The aim of this study was to calculate the LSC in an obese population., Methods: We performed an interventional study among 120 obesity patients, in whom two measurements of BMD were performed at 3 sites. Pairs of measures were used to calculate the LSC, using the Bland and Altman method., Results: We calculated that the LSC was 0.046 g/cm² at the lumbar spine, 0.069 g/cm² at the femoral neck, and 0.06 g/cm² at the total hip. We also calculated the LSC for each class of obesity and observed an increase in LSC with increasing body mass index (BMI). We calculated a LSC of 0.05 g/cm² in patients with class 2 or class 3 obesity, whereas the LSC in patients with class 1 obesity is similar to the threshold used in the general population., Discussion: In obese population, like BMD, LSC is higher than the threshold value of the general population, and increases with increasing BMI., Conclusion: LSC of 0.05 g/cm² could be used in clinical practice in patients with class 2 or 3 obesity. These findings should help to improve the interpretation of BMD scans in these patients and optimize their management., Trial Registration Number: Comité de Protection des Personnes Ile-de France VII, France., (© 2024.

Objective: We assess the clinical and structural impact at two years of progressively spacing tocilizumab (TCZ) or abatacept (ABA) injections versus maintenance at full dose in patients with rheumatoid arthritis in sustained remission., Methods: This multicenter open-label noninferiority (NI) randomized clinical trial included patients with established rheumatoid arthritis in sustained remission receiving ABA or TCZ at a stable dose. Patients were randomized to treatment maintenance (M) at full dose (M-arm) or progressive injection spacing (S) driven by the Disease Activity Score in 28 joints every 3 months up to biologics discontinuation (S-arm). The primary end point was the evolution of disease activity according to the Disease Activity Score in 44 joints during the 2-year follow-up analyzed per protocol with a linear mixed-effects model, evaluated by an NI test based on the one-sided 95% confidence interval (95% CI) of the slope difference (NI margin 0.25). Other end points were flare incidence and structural damage progression., Results: Overall, 202 of the 233 patients included were considered for per protocol analysis (90 in S-arm and 112 in M-arm). At the end of follow-up, 16.2% of the patients in the S-arm could discontinue their biologic disease-modifying antirheumatic drug, 46.9% tapered the dose and 36.9% returned to a full dose. NI was not demonstrated for the primary outcome, with a slope difference of 0.10 (95% CI 0.10-0.31) between the two arms. NI was not demonstrated for flare incidence (difference 42.6%, 95% CI 30.0-55.1) or rate of structural damage progression at two years (difference 13.9%, 95% CI -6.7 to 34.4)., Conclusion: The Towards the Lowest Efficacious Dose trial failed to demonstrate NI for the proposed ABA or TCZ tapering strategy., (© 2023 The Authors.

The objectives of our study were to assess retention rate, safety, and predictive factors for retention of subcutaneous (SC) TNF inhibitors (TNFi) (adalimumab (ADA), etanercept (ETN), golimumab (GOL), and certolizumab pegol (CZP)) in axial spondyloarthritis (axSpA) depending on the line of treatment in real-life conditions. A multicentre retrospective observational study was conducted including 552 patients fulfilling the ASAS criteria for axSpA followed in the RIC-France register who began SC-TNFi between 01/01/13 and 08/31/2018 for a total of 824 prescriptions. Taking all lines of treatment into account, GOL had a significantly higher retention rate compared with ADA, ETN, and CZP with a mean retention length of 59 months. As first-line bDMARDs, GOL had a significantly higher retention rate compared with ADA and ETN. ETN had the best retention rate when prescribed as at least 3rd bDMARD. Taking all lines of treatment into account, female sex, peripheral disease, BASDAI at initiation, and line of treatment were predictive factors for treatment cessation. Primary inefficiency was the most frequent reason for treatment cessation. In conclusion, GOL showed the highest retention rate in axSpA. Male sex, absence of peripheral disease, and early line of prescription were associated with better SC-TNFi retention in axSpA., (© 2024. The Author(s).)

Introduction: RA-BE-REAL is a 3-year, multinational, prospective, observational study of adult patients with rheumatoid arthritis (RA) evaluating time to discontinuation of initial RA treatment along with patient baseline characteristics. This study's primary objective was to assess the time to discontinuation of initial baricitinib, any other targeted synthetic disease-modifying anti-rheumatic drug (tsDMARD), or any biologic disease-modifying anti-rheumatic drug (bDMARD) treatment for all causes (excluding sustained clinical response) over 24 months in a European population., Methods: Patients initiated treatment with baricitinib (cohort A) or any bDMARD or tsDMARD (cohort B) for the first time. This study's primary objective was to assess the time to discontinuation of initial baricitinib, any other targeted synthetic disease-modifying anti-rheumatic drug (tsDMARD), or any biologic disease-modifying anti-rheumatic drug (bDMARD) treatment for all causes (excluding sustained clinical response) over 24 months in a European population. Comparative effectiveness analyses, over 24 months, included time to treatment discontinuation for all causes (excluding sustained clinical response), percentage of patients achieving Clinical Disease Activity Index (CDAI) remission or low disease activity (LDA), as well as mean changes from baseline for CDAI, pain visual analogue scale, and the Health Assessment Questionnaire-Disability Index (HAQ-DI). For this European subpopulation, comparative analyses were performed using a frequentist model averaging (FMA) framework based on a data-driven machine learning causal inference approach to compare time to discontinuation, effectiveness, rates of remission or LDA, and patient-reported outcomes over 24 months comparing baricitinib with TNFi, as well as non-TNFi and tsDMARD grouped as other mechanism of action (OMA) drugs., Results: In the European sample of RA-BE-REAL, patients with RA treated with baricitinib experienced fewer discontinuations in comparison to those treated with tumour necrosis factor inhibitors or OMA. Overall, patients naïve to b/tsDMARDs achieved a higher rate of LDA and remission compared with experienced patients. A significantly greater proportion of patients treated with baricitinib achieved LDA compared with b/tsDMARDs., Conclusion: This real-world data can better inform clinicians about baricitinib effectiveness and drug survival when prescribing treatment for patients with RA across different subpopulations., (© 2023.

Background and Objectives: Methotrexate (MTX) is the first-line therapy for rheumatoid arthritis (RA). While therapeutic adherence is essential to successful management, no objective MTX assay is currently available. Using population pharmacokinetic modelling (PopPK), our objective was to describe the urinary MTX (MTXu) kinetics in treated patients and to evaluate its abilities to assess the MTX-adherence., Methods: The association between urinary methotrexate level and methotrexate administration was assessed using a generalized linear model. Then, a population pharmacokinetic model was developed based on data from 59 patients using with Monolix 2021. R2. Simulations were run to establish a reference kinetic profile and evaluate the proportion of samples predicted as true positives., Results: Compared to the control group, multivariate analysis showed that MTXu was independently associated with methotrexate administration (p < 0.0001) with a sensitivity and specificity greater than 99%. The final PopPK model selected was a two-compartment model with first-order absorption and elimination. Internal and external validation of the model met all predefined criteria. When using an analytical assay with a LOQ equal to 1 nM, the proportion of samples predicted as true positives is over 90%, as a function of MTX dose (7.5-25 mg/week) and post-administration sampling days (1-7 days)., Conclusion: We developed a pharmacokinetic model able to describe expected patterns of urinary methotrexate. This allowed us to propose a new objective test of MTX adherence, which could help in routine practice to differentiate patients who are truly unresponsive to methotrexate from those who are unresponsive because of non-adherence., Competing Interests: Declaration of Competing Interest All authors have no conflicts to disclose., (Copyright © 2023 The Authors.

Background: Patients with rheumatoid arthritis (RA) and other chronic inflammatory rheumatic disorders have increased risk of cardiovascular disease (CVD) and venous thromboembolism (VTE) compared with the general population. Moreover, recent data have raised concerns around a possible increased risk of major CV events (MACE) and VTE in patients treated with JAK inhibitors (JAKi). In October 2022, the PRAC has recommended measures to minimize the risk of serious side effects, including CV conditions and VTE, associated with all approved in chronic inflammatory diseases., Objective: To provide an adequate and feasible strategy to evaluate, at the individual level, the risk of CVD and VTE in patients with chronic inflammatory rheumatic diseases., Methods: A multidisciplinary steering committee comprised 11 members including rheumatologists, a cardiologist, a hematologist expert in thrombophilia and fellows. Systematic literature searches were performed and evidence was categorized according to standard guidelines. The evidence was discussed and summarized by the experts in the course of a consensus finding and voting process., Results: Three overarching principles were defined. First, there is a higher risk of MACE and VTE in patients with chronic inflammatory rheumatic diseases compared with the general population. Second, the rheumatologist has a central role in the evaluation of the risk of CVD and VTE in patient with chronic inflammatory rheumatic diseases. Third, the risk of MACE and VTE should be regularly assessed in patients with chronic inflammatory rheumatic diseases, particularly before initiating targeted therapies. Eleven recommendations were defined to prevent potentially life-threatening complications of CVD and VTE in patients with chronic inflammatory rheumatic diseases, providing practical assessment of CVD and VTE before considering the prescription of targeted therapies, and especially JAKi., Conclusion: These practical recommendations based on expert opinion and scientific evidence provide consensus for the prevention and the assessment of CVD and VTE., (Copyright © 2023 The Authors.

Ocular graft versus host disease (OGvHD) develops after allogeneic hematopoietic stem cell transplantation (HSCT) and manifests as ocular surface inflammatory disease. This study evaluated the efficacy of adeno-associated virus (AAV) gene therapy encoding human leukocyte antigen G (HLA-G) to inhibit OGvHD. A major histocompatibility mismatch chronic OGvHD murine model was evaluated. 7 days after HSCT, mice were dosed subconjunctivally with scAAV8-HLA-G1/5 (1 x 10 9 vg/eye), topical cyclosporine (twice daily), or left untreated. Body weights and tear production (red thread test) were recorded, and eyelid, corneal opacity, and corneal fluorescein retention were scored through day 44 after HSCT. Tissues were collected for vector biodistribution, ocular histology, and immunofluorescence. Compared with untreated HSCT eyes, those dosed with scAAV8-HLA-G1/5 had significantly reduced clinical inflammatory signs of OGvHD. On histology, eyes that received scAAV8-HLA-G1/5 or cyclosporine had a significantly lower mean limbal mononuclear cell count when compared with non-treated HSCT eyes. HLA-G immunofluorescence was detected in the subconjunctiva and peripheral cornea in HSCT animals treated with scAAV8-HLA-G1/5. Vector genomes were detected in the lacrimal gland, but not in the other tested organs. These results provide evidence that subconjunctival AAV targets ocular surface and corneal disease and support that HLA-G-based gene therapy may be an effective treatment for OGvHD., Competing Interests: M.L.H. and B.C.G. are coinventors of the AAV-HLA-G technology evaluated herein and are listed on a patent (pending) that is owned by the University of North Carolina and North Carolina State University.

Many studies have shown the effectiveness of platelet-rich plasma (PRP) in the treatment of knee osteoarthritis. We aimed to determine the factors associated with good or poor response to PRP injections in knee osteoarthritis. This was a prospective observational study. Patients with knee osteoarthritis were recruited from a university hospital. PRP was injected twice at a one-month interval. Pain was assessed on a visual analog scale (VAS) and function was assessed using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Radiographic stage was collected and defined according to the Kellgren-Lawrence classification. Patients were classified as responders if they met the OMERACT-OARSI criteria at 7 months. We included 210 knees. At 7 months, 43.8% were classified as responders. Total WOMAC and VAS were significantly improved between M0 and M7. Physical therapy and a heel-buttock distance >35 cm were the two criteria associated with poor response at M7 by multivariate analysis. Pain VAS at M7 appeared to be lower in patients with osteoarthritis for less than 24 months. No adverse effects were reported. PRP treatment in knee osteoarthritis appears to be well-tolerated and effective, even in patients who reacted poorly to hyaluronic acid. Response was not associated with radiographic stage.

Introduction: RA-BE-REAL has the overall aim of defining a profile of patients with rheumatoid arthritis (RA) starting baricitinib or any other targeted synthetic (ts) or any biologic (b) disease-modifying antirheumatic drug (DMARD) for the first time, and the primary objective of estimating time until discontinuation from any cause (excluding sustained response) of the initial treatment., Methods: RA-BE-REAL is an ongoing, prospective, observational, 36-month study in patients with RA initiating treatment with baricitinib (cohort A) or any other tsDMARD or any bDMARD (cohort B) for the first time. The primary objective is to assess the time until treatment discontinuation from any cause (excluding sustained response) at 24 months, (i.e., the rate of discontinuation of initial baricitinib or ts/bDMARD). Patient profiles of each cohort are described and compared. Post-baseline data are descriptively analyzed. This manuscript presents baseline and interim (6-month) outcomes for European patients with RA participating in the global RA-BE-REAL study., Results: Data from 1074 patients (cohort A: 509; cohort B: 565) were analyzed. For cohorts A and B, respectively, the 6-month cumulative incidence (95% confidence interval) of treatment discontinuation was 16.5 (12.9-21.1) and 23.3 (19.1-28.2), and the proportions of patients achieving remission were 25.6% and 18.5%. At baseline, mean patient age was 59.1 and 57.0 years (p = 0.010) and mean disease duration was 10.0 and 8.9 years (p = 0.047), respectively. The proportions of patients exposed to ts/bDMARDs at any time before study entry were 51.9% and 39.1%, and the proportions of patients initiated on monotherapy were 50.9% and 31.2%, respectively., Conclusion: In real-world settings, patients with RA initiating treatment with baricitinib were older and had longer disease duration than those initiating treatment with any other tsDMARD or any bDMARD. Initial descriptive data regarding treatment discontinuation (including reasons for discontinuation), effectiveness, and treatment patterns will be enriched as the study progresses., (© 2022.

Survival improvement in cystic fibrosis (CF) is associated with more frequent long-term complications, including CF related bone disease (CFBD). Impact of CFBD on global health outcome remains poorly described. We aimed to assess the relationship between low bone mineral density (BMD) and spinal pain, disability, and quality of life in CF adult patients. This monocentric cross-sectional study with prospective data collection was conducted from November 2016 to December 2019 in the Department of Respiratory Diseases at the University Hospital of Reims (NCT02924818). BMD was assessed by X-ray absorptiometry (DXA). Disability was assessed by the Health Assessment Questionnaire (HAQ). Quality of life was assessed by both the St George's Respiratory Questionnaire and the Cystic Fibrosis Questionnaire for teenagers and adults (CFQ 14+). Forty patients were analyzed, 68% of men, with a median age of 25 years, a median body mass index of 21 kg/m² and a median FEV1% of 54%. Nine patients (23%) had spinal pain. Ten patients (25%) had a low BMD. Compared with patients with normal BMD, patients with low BMD had a significantly lower BMI (22 vs 19 kg/m²; P = .006) and less vitamin D supplementation (33% vs 0%; P = .035). Low BMD was not associated with spinal pain, disability and quality of life. Low BMD is frequent in CF, affecting 1-quarter of adult patients. No significant association was found between low BMD and spinal pain, disability or quality of life., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2022 the Author(s).

Background: Use of a combination of targeted therapies (COMBIO) in patients with refractory/overlapping immune-mediated inflammatory diseases (IMIDs) has increased, but reported data remain scarce. We aimed to assess effectiveness and safety of COMBIO in patients with IMIDs., Methods: We conducted a French ambispective multicenter cohort study from September 2020 to May 2021, including adults' patients with 1 or 2 IMIDs and treated at least 3-month with COMBIO., Results: Overall, 143 patients were included. The most common IMIDs were Crohn's disease (63.6%), axial spondyloarthritis (37.7%), and ulcerative colitis (14%). Half of patients had only one IMID, of which 60% were Crohn's disease. Mean duration of COMBIO was 274.5±59.3 weeks, and COMBIO persistence at 104 weeks was estimated at 64.1%. The most frequent COMBIOs combined anti-TNF agents with vedolizumab (30%) or ustekinumab (28.7%). Overall, 50% of patients achieved significant and 27% mild-to-moderate improvement in patient-reported outcomes. Extended duration of COMBIO (aOR=1.09; 95% CI: 1.03-1.14; p=0.002) and diagnoses of two IMIDs (aOR=3.46; 95%CI: 1.29-9.26; p=0.013) were associated with significant improvement in patient-reported outcomes. Incidence of serious infection during COMBIO was 4.51 per 100 person-years (95% CI 2.20-8.27) and 5 COMBIOs were discontinued due to adverse events., Conclusions: COMBIO can be effective and safe in patients with refractory/overlapping IMIDs., Competing Interests: Declaration of Competing Interest L Guillo declares consulting fees for Abbvie.

Introduction: We aimed to evaluate the efficacy and tolerance of A1 pulley release using the needle technique, under ultrasound guidance, in patients with symptomatic trigger finger., Methods: All patients with symptomatic trigger finger underwent A1 pulley release using an intramuscular 21 gauge (G) needle. Quinnell grade (I-IV), Quick Disabilities of Arm, Shoulder & Hand (QuickDASH) score (0-100) and pain score on a visual analog scale (VAS: 0-10mm) were recorded at inclusion. The primary endpoint was complete resolution of the trigger finger at 6 months., Results: Eighty-four patients totaling 105 treated digits were included. Mean age was 63.3±10.7 years. Prior to treatment, mean VAS pain score was 5.8±2.6mm, and mean QuickDASH score was 44.3±19.1. At 6 months, disappearance of symptoms was achieved in 85 of 91 digits with follow-up (93.4%), and in 85.7% at 12 months. The absolute reduction in VAS pain and QuickDASH scores at 6 months was respectively 4.1±3.1 (P<0.001) and 36.1±20.7 (P<0.001), and 90% of patients reported being satisfied or very satisfied at 6 months. Long duration of symptoms was significantly associated with persistent trigger finger at 6 months after intervention. Complications were rare and minor. Tenosynovitis occurred in 5.7% of cases, for which a corticosteroid injection into the tendon sheath rapidly led to favorable resolution., Conclusion: Treatment of trigger finger by release of the A1 pulley under ultrasound guidance using the needle technique is a mildly invasive technique that yields rapid and effective symptom resolution with good tolerance up to 12 months., (Copyright © 2022 Société française de rhumatologie.

Objectives: Previous studies demonstrated equivalence in terms of efficacy and safety of biosimilars (bsDMARDs) compared to original treatments (boDMARDs) and in switching situations. Less is known about what happens when initiating a bsDMARD in a molecule naïve patient. The objectives of our study were to compare the retention of treatment of subcutaneous boDMARDs and bsDMARDs globally, depending on the disease [rheumatoid arthritis (RA), spondyloarthritis (SpA), or psoriatic arthritis (PsA)], molecule [etanercept (ETN) or adalimumab (ADA)], line of treatment, or presence of citrate in the context of first use of each molecule (namely initiation) and to analyze treatment retention's predictive factors., Materials and Methods: This multicenter retrospective study used data from shared medical records of the RIC-FRANCE network, encompassing the prescription of hospital rheumatologists and attached practitioners, of patients with RA, SpA, or PsA, with the starting ETN between 03/10/2016 and 31/07/2020, or ADA between 23/10/2018 and 31/07/2020. Clinical data were collected from medical records. Retention analysis was performed using Kaplan-Meier curves and the log-rank test. Retention's predictive factors were analyzed using Cox proportional-hazard ratio., Results: Eight hundred forty-five prescriptions were analyzed: 340 boDMARDs and 505 bsDMARDs. About 57% of prescriptions concerned women. The mean age was 51.8 years. About 38% were prescriptions for RA, 16% for PsA, and 46% for SpA. An increase in the initiation over time was observed for both ETN and ADA. The retention rate of bsDMARDs was superior to boDMARDs' one (39 vs. 23 months; p = 0.045). When molecules are compared, the difference was significant only for ETN (45 vs. 19 months for boDMARD; p = 0.0265). When comparing diseases, the difference in favor of bsDMARDs was significant in patients with RA only ( p = 0.041). Citrated treatments displayed better retention compared to citrate-free treatments ( p = 0.0137). Multivariable analysis of predictive factors for the cessation of treatment found shorter disease duration, boDMARD prescription, hospital practitioner prescription, late line of treatment, and female sex as significant. More side effects were observed with boDMARDs, especially more infections (17.8% vs. 7.8%)., Conclusion: Even if bsDMARDs' prescription increases over time, its penetration rate is still below expectations. bsDMARDs displayed better retention compared to boDMARDs, especially for ETN, and in patients with RA. Citrated treatments had better retention. Prescription by a full-time hospital-based rheumatologist is associated with poorer retention., Competing Interests: GL received support for attending meetings from NOVARTIS, GSK, and AMGEN.

Equine recurrent uveitis (ERU) is a spontaneous, painful, and vision threatening disease affecting up to 25% of equine populations worldwide. Current treatments of ERU are non-specific and have many side effects which limits them to short-term use. In order to develop an effective therapy for ERU, we investigated the use of adeno-associated virus (AAV) gene therapy, exploiting a natural immune tolerance mechanism induced by equine interleukin-10 (Equine-IL10). The purpose of this study was to evaluate the therapeutic efficacy of a single intravitreal (IVT) dose of AAV8-Equine-IL10 gene therapy for inhibition of experimental autoimmune uveitis (EAU) in rats. Each rat was dosed intravitreally (IVT) in both eyes with either balanced salt solution (BSS) (control; n = 4), AAV8-Equine-IL10 at a low dose (2.4x109 vg; n = 5) or high dose (2.4x1010 vg; n = 5). EAU was induced in all groups of rats 7 days after IVT injections and euthanized 21 days post-injection. Ophthalmic examination and aqueous humor (AH) cell counts were recorded with the observer blinded to the treatment groups. Histopathology and qPCR were performed on selected ocular tissues. Data presented herein demonstrate that AAV8-Equine-IL10 treated rats exhibited a significant decrease in clinical inflammatory scores and AH cell counts compared to BSS-treated EAU eyes on days 10, 12 and 14 post EAU induction at both administered vector doses. Mean cellular histologic infiltrative scores were also significantly less in AAV8-Equine-IL10 dosed rats compared to the BSS group. Intravitreal injection of AAV8-Equine-IL10 resulted in Equine-IL10 cDNA expression in the ciliary body, retina, cornea, and optic nerve in a dose-dependent manner. A single IVT injection of AAV8-Equine-IL10 appeared to be well-tolerated and inhibited EAU even at the lowest administered dose. These results demonstrate safety and efficacy of AAV8-Equine-IL10 to prevent EAU and support continued exploration of AAV gene therapy for the treatment of equine and perhaps human recurrent uveitis., Competing Interests: The authors have declared that no competing interests exist.

Background: The mid-term respiratory sequelae in survivors of severe COVID-19 appear highly heterogeneous. In addition, factors associated with respiratory sequelae are not known. In this monocentric prospective study, we performed a multidisciplinary assessment for respiratory and muscular impairment and psychological distress 3 months after severe COVID-19. We analysed factors associated with severe persistent respiratory impairment, amongst demographic, COVID-19 severity, and 3-month assessment., Methods: Patients with severe SARS-CoV-2 pneumonia requiring ≥ 4L/min were included for a systematic 3-month visit, including respiratory assessment (symptoms, lung function, CT scan), muscular evaluation (body composition, physical function and activity, disability), psychopathological evaluation (anxiety, depression, post-traumatic stress disorder-PTSD) and quality of life. A cluster analysis was performed to identify subgroups of patients based on objective functional measurements: D LCO , total lung capacity and 6-min walking distance (6MWD)., Results: Sixty-two patients were analysed, 39% had dyspnea on exercise (mMRC ≥ 2), 72% had D LCO  < 80%, 90% had CT-scan abnormalities; 40% had sarcopenia/pre-sarcopenia and 31% had symptoms of PTSD. Cluster analysis identified a group of patients (n = 18, 30.5%) with a severe persistent (SP) respiratory impairment (D LCO 48 ± 12%, 6MWD 299 ± 141 m). This SP cluster was characterized by older age, severe respiratory symptoms, but also sarcopenia/pre-sarcopenia, symptoms of PTSD and markedly impaired quality of life. It was not associated with initial COVID-19 severity or management., Conclusions and Clinical Implication: We identified a phenotype of patients with severe persistent respiratory and muscular impairment and psychological distress 3 months after severe COVID-19. Our results highlight the need for multidisciplinary assessment and management after severe SARS-CoV-2 pneumonia. Trial registration The study was registered on ClinicalTrials.gov (May 6, 2020): NCT04376840., (© 2022. The Author(s).)

Purpose: To determine if inhibition of Myristoylated Alanine Rich C Kinase Substrate (MARCKS) protein, using novel MARCKS inhibitor peptides, will reduce the severity of endotoxin-induced uveitis (EIU) in rats. Methods: EIU was induced in Lewis rats using subcutaneous administration of lipopolysaccharide. In the first phase of the study, 3 different novel MARCKS inhibitor peptides that mimic the N-terminal region of MARCKS (BIO-11006, or lower molecular weight analogs BIO-91201 or BIO-91202; Biomarck Pharmaceuticals, Ltd., Newtown, PA) were administered intravitreally (IVT) at 50 and 100 μM. In the second phase, BIO-91201 was administered IVT at 10, 50, and 100 μM and topically at the 100 μM concentration. The efficacy of MARCKS inhibitor peptides was assessed by clinical examination using slit lamp biomicroscopy, optical coherence tomography (OCT) anterior chamber cell counts, histopathology, and aqueous humor cytokine analysis. Results: Clinical scores were significantly reduced 24 h following uveitis induction in the first phase of the study in the following treatment groups: BIO-11006 50 μM IVT and 100 μM IVT, BIO-91201 50 μM IVT, and BIO-91202 100 μM IVT ( P  < 0.05). OCT anterior chamber cell counts were significantly reduced in the first phase of the study in all treatment groups ( P  < 0.001). OCT anterior chamber cell counts and histopathology scores were significantly reduced in the second phase of the study in the BIO-91201 50 μM IVT group ( P  < 0.05). No effect was seen with topical administration. Conclusion: MARCKS inhibitor peptides were effective in reducing the severity of ocular inflammation and cellular influx in EIU.

Background: Obesity is a risk factor for dyspnea. However, investigations of daily living obesity-related dyspnea are limited and its mechanisms remain unclear. We conducted a cross-sectional study to analyze the relationships between dyspnea in daily living, lung function, and body composition in patients with obesity., Methods: One-hundred and thirty patients (103 women/27 men), candidate for bariatric surgery, with a mean ± SD Body Mass Index (BMI) of 44.8 ± 6.8 kg/m 2 were included. Dyspnea was assessed by the modified Medical Research Council (mMRC) scale. Comorbidities, laboratory parameters, pulmonary function tests, arterial blood gases, six-minute walk test (6MWT), handgrip strength, and DXA body composition were analyzed., Results: Thirty-one percent of patients exhibited disabling dyspnea in daily living (mMRC ≥ 2). Compared with patients without disabling dyspnea (mMRC < 2), significant dyspnea (mMRC ≥ 2) was associated with a lower 6MWT distance (395 ± 103 m vs 457 ± 73 m, p < 0.001), lower lung volumes including Expiratory Reserve Volume (42 ± 28% vs 54 ± 27%, p = 0.024), Vital Capacity (95 ± 14 vs 106 ± 15%, p < 0.001) and Forced expiratory volume in one second (95 ± 13 vs 105 ± 15%, p = 0.002), a higher BMI (48.2 ± 7.7 vs 43.2 ± 5.7 kg/m 2 , p = 0.001) and a higher percentage of fat mass in the trunk (46 ± 5 vs 44 ± 5 p = 0.012) and android region (52 ± 4 vs 51 ± 4%, p = 0.024). There was no difference regarding comorbidities (except hypertension), laboratory parameters, and sarcopenia markers between patients with (mMRC ≥ 2) and without (mMRC < 2) disabling dyspnea., Conclusion: Dyspnea in patients with obesity is associated with a reduction in lung volumes and a higher percentage of fat mass in central body regions. How dyspnea and body composition may change with interventions like physical activity or bariatric surgery remains to be investigated., (© 2022. The Author(s).)

Background: With the improvement of cystic fibrosis (CF) patient survival, the prevalence of long-term complications increased, among them rheumatologic disorders., Methods: The aim of this prospective study was to evaluate the prevalence of spinal and joint pain, and their impact on disability, anxiety, depression, and quality of life in CF adult patients., Results: Forty-seven patients were analyzed, 72% of men, mean aged 28 years, with a mean body mass index of 22 kg/m 2 and a mean FEV 1 % of 63%. Twenty-two patients (47%) described rheumatologic pain either spinal ( n = 15, 32%) and/or joint pain ( n = 14, 30%). Patients with spinal and/or joint pain were shorter ( p = 0.023), more frequently colonized with Staphylococcus aureus ( p < 0.008), had more frequent ΔF508 homozygous mutations ( p = 0.014), and a trend for more impairment of the 6-min walking distance ( p = 0.050). The presence of rheumatologic pain tended to be associated with disability according to the Health Assessment Questionnaire (HAQ) and anxiety. Compared with patients with no pain patients with both spinal and joint pain exhibited a more pronounced impact on the St George's Respiratory Questionnaire (SGRQ)., Conclusion: Rheumatologic pain is frequent in CF adult patients, and may affect daily living, anxiety and quality of life. Systematic assessment of rheumatologic pain should be included in the management of CF patients., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Schmoll, Launois, Perotin, Ravoninjatovo, Griffon, Carré, Mulette, Ancel, Hagenburg, Lebargy, Deslée, Salmon and Dury.)

Introduction : Biologic treatments are a milestone in the management of rheumatoid arthritis (RA) patients with an inadequate response to conventional synthetic treatments. With the increase in the number of biologic treatments, predictor factors of discontinuation are needed to choose the right treatment for the right patient. Areas covered : In this article, the factors affecting persistence with biologic treatments will be covered: factors associated with the demographic characteristics and comordidities of the patients, those with the characteristics of the disease, the biomarkers, and the adherence. Expert opinion : Seeking factors affecting persistence with biologic treatments is an important field of clinical research to offer the best management to the RA patients. Personalized medicine is the ultimate goal in this field to choose the biological therapy with the highest persistence for every patient. To achieve this goal, biomarkers could be a milestone.

Objectives: To evaluate the characteristics of patients (pts) with PsA treated by ustekinumab (UST) or secukinumab (SEK) and to compare real-world persistence of UST and SEK in PsA., Methods: In this retrospective, national, multicentre cohort study, pts with PsA (CASPAR criteria or diagnosis confirmed by the rheumatologist) initiating UST or SEK with a follow-up ≥6 months were included from January 2011 to April 2019. The persistence between SEK and UST was assessed after considering the potential confounding factors by using pre-specified propensity-score methods. Causes of discontinuation and tolerance were also collected., Results: A total of 406 pts were included: 245 with UST and 161 with SEK. The persistence rate was lower in the UST group compared with the SEK group [median persistence 9.4 vs 14.7 months; 26.4% vs 38.0% at 2 years; weighted hazard ratio (HR) = 1.42; 95% CI: 1.07, 1.92; P =0.015]. In subgroup analysis, the persistence rate of SEK associated with MTX was significantly higher than that of UST associated with MTX: HR = 2.20; 95% CI: 1.30, 3.51; P =0.001, in contrast to SEK vs UST monotherapy: HR = 1.06; 95% CI: 0.74, 1.53; P =0.75. Discontinuation due to inefficacy was reported in 91.7% (SEK) and 82.4% (UST) of pts. Discontinuation due to an adverse event was reported in 12.2% (SEK) and 7.7% (UST) of pts., Conclusion: In this first study comparing UST and SEK, the persistence of SEK was higher than that of UST in PsA. In subgroup analysis, this difference was only found in association with MTX., (© The Author(s) 2020. Published by Oxford University Press on behalf of the British Society for Rheumatology.

Purpose: To explore the effects of chronic, uncontrolled glaucoma on pressure sensitivity in dogs before and after enucleation of the painful globe., Methods: Client-owned dogs undergoing enucleation for chronic glaucoma with no other sources of pain were enrolled. Normal dogs of similar breeds and skull morphology were enrolled as controls. Craniofacial ratio (CFR) and relative palpebral fissure width (RPFW) were assessed in all patients. Serial mechanical quantitative sensory testing (QST) was performed the day before surgery, and 14, 30, 60, and 120 days after surgery. QST consisted of electronic Von Frey (eVF), and blunt algometry (BA) performed above and below the nonglaucomatous eye, the metacarpus, and metatarsus. Cochet-Bonnet esthesiometry (CB) was also performed on the remaining eye., Results: Twelve dogs (6 per group) were included. Compared to baseline values, sensitivity tended to decrease over time (increased thresholds) in treatment dogs while it stayed constant or increased slightly in control dogs. The difference in change from baseline sensitivity between control and treatment groups was significant at day 120 using BA at supraorbital (P = .0153), infraorbital (P = .0209), and metacarpal sites (P = .007) and overall (P = .0470). This divergence was also significant using CB (P = .0470) on the opposite cornea. As patient CFR and RPFWV increased, both eVF (P = .005-.023) and BA (P = .004-.041) increased., Conclusions: Sensitivity to mechanical stimuli decreased both locally and at remote sites in dogs following enucleation for painful chronic glaucoma. Cranial conformation is associated with differences in sensitivity., (© 2020 American College of Veterinary Ophthalmologists.)

Purpose: Determine optimal iontophoresis times for riboflavin delivery to the corneal stroma across different species and compare these to corneal injection., Methods: Ex vivo horse, dog, rabbit, and pig globes were treated with riboflavin administered with either iontophoresis for 2.5-20 minutes with or without corneal epithelium; or with purpose-designed precise corneal injection (PCI) application with intact epithelium. Immediately following riboflavin administration, samples were harvested, frozen, and sectioned. Riboflavin penetration was imaged using fluorescence microscopy., Results: Horse samples processed with iontophoresis without epithelium for 2.5, 5, and 7.5 minutes, and processed with intact epithelium for 20 minutes, had mean percent stromal penetration (%SP mean ) of 63.4%, 93.8%, 100.0%, and 0.0% (respectively). Dog samples processed with iontophoresis without epithelium for 2.5 and 5 minutes, had %SP mean of 60.7% and 82.1% (respectively). Pig samples processed with iontophoresis for 5 minutes without and with epithelium had %SP mean of 63.3% and 35.1% (respectively). Rabbit samples processed with iontophoresis without epithelium for 2.5 and 5 minutes, had %SP mean of 81.8% and 100.0% (respectively). For all injected volumes, riboflavin was observed spanning throughout the corneal stroma, and lamellar separation was noted surrounding all sites of injection., Conclusions: Both iontophoresis and injection via PCI needles provide efficient and effective means of riboflavin administration in ex vivo horse, dog, rabbit, and pig corneas. Epithelial debridement is required for stromal delivery of riboflavin using iontophoresis in horses. Following epithelial removal, riboflavin penetrated through the horse corneal stroma faster than all other species tested., (© 2020 American College of Veterinary Ophthalmologists.)

The chronic ocular toxicity, tolerability, and inflammation following corneal intrastromal injection of saline or escalating doses of an adeno-associated virus (AAV) containing a codon-optimized α-l-iduronidase (AAV-opt- IDUA ) expression cassette were evaluated in New Zealand White rabbits. Corneal opacity following corneal intrastromal injection resolved by 24 h. Mild elevation of clinical ocular inflammation was observed 24 h after injection, but it returned to baseline by day 7 and no abnormalities were noted through 6 months of observation after injection. Vector genomes and IDUA cDNA were detected in the injected corneas in a dose-dependent manner. Both the lowest administered AAV-opt- IDUA dose, shown to be effective in mucopolysaccharidosis type I (MPS I) dogs, and a 10-fold higher dose of AAV-opt- IDUA resulted in no detectable immunologic response or adverse effect in rabbits. Vector genomes outside of the eye were rarely detected following corneal intrastromal injection of AAV-opt- IDUA , and neutralizing antibodies to the AAV capsid were not present at the experimental conclusion. This study, combined with our previous studies in MPS I dogs, suggests that AAV-opt- IDUA corneal gene therapy following corneal intrastromal injection of AAV-opt- IDUA has the potential to prevent and reverse blindness in MPS I patients in a safe and effective manner., (© 2020 The Author(s).)

Tumour necrosis factor-α [TNF-α] inhibitors have revolutionised the management of chronic inflammatory conditions. A number of cutaneous adverse events have been reported with TNF inhibition, including vasculitis. Most reactions are mild and rarely warrant treatment withdrawal. Here we describe a patient with Crohn's disease treated with adalimumab in whom severe multivisceral Henoch-Schönlein purpura developed, including neurological involvement, requiring definitive TNF blocker withdrawal., (Copyright © 2019 European Crohn’s and Colitis Organisation (ECCO).

Objectives: Data on abatacept (ABA) persistence in routine practice are limited. We aimed to study ABA persistence rates at 12 months, according to the date of initiation, and to analyze the factors associated with persistence at 12 months., Methods: We performed an observational, ambispective, multi-center study from January 2008 to July 2016, based on the French-RIC Network. We defined three groups of patients followed up for rheumatoid arthritis (RA), according to the date of initiation of ABA therapy: Group 1 (from 2007 to 31 July 2010: ABA indicated after anti-TNF failure); Group 2 (from 1 August 2010 to 31 March 2014: ABA indicated after conventional antirheumatic drugs failure); Group 3 (from 1 April 2014 to 1 July 2016: ABA available by the subcutaneous injection)., Results: Among 517 patients who initiated ABA, drug persistence at 12 months was 68%. The only factor significantly associated with persistence rate at 12 months was C-reactive protein (CRP) < 10 mg/L at ABA initiation (odds ratio (OR) 0.6, 95% confidence interval 0.3-0.9; p = 0.0016). There was no significant difference in drug persistence according to date of initiation, the line of biological disease-modifying antirheumatic drugs (bDMARD) therapy or the route of administration., Conclusions: In routine practice, over time, ABA has come to be initiated earlier in the course of therapy for RA in France. Abatacept persistence is similar to that reported in the Orencia Rheumatoid Arthritis (ORA) registry, and does not differ according to the date of initiation. The only factor found to be associated with the persistence rate at 12 months was CRP < 10 mg/L at ABA initiation., Competing Interests: The authors declare no conflicts of interest.

Non-infectious uveitis (NIU) is an intractable, recurrent, and painful disease that is a common cause of vision loss. Available treatments of NIU, such as the use of topical corticosteroids, are non-specific and have serious side effects which limits them to short-term use; however, NIU requires long-term treatment to prevent vision loss. Therefore, a single dose therapeutic that mediates long-term immunosuppression with minimal side effects is desirable. In order to develop an effective long-term therapy for NIU, an adeno-associated virus (AAV) gene therapy approach was used to exploit a natural immune tolerance mechanism induced by the human leukocyte antigen G (HLA-G). To mimic the prevention of NIU, naïve Lewis rats received a single intravitreal injection of AAV particles harboring codon-optimized cDNAs encoding HLA-G1 and HLA-G5 isoforms one week prior to the induction of experimental autoimmune uveitis (EAU). AAV-mediated expression of the HLA-G-1 and -5 transgenes in the targeted ocular tissues following a single intravitreal injection of AAV-HLA-G1/5 significantly decreased clinical and histopathological inflammation scores compared to untreated EAU eyes (p < 0.04). Thus, localized ocular gene delivery of AAV-HLA-G1/5 may reduce the off-target risks and establish a long-term immunosuppressive effect that would serve as an effective and novel therapeutic strategy for NIU, with the potential for applications to additional ocular immune-mediated diseases.

Objectives: We performed a systematic review and meta-analysis of the current literature to assess the safety of combining two biologic disease-modifying antirheumatic drugs (bDMARDs) in the treatment of rheumatoid arthritis (RA)., Methods: We systematically searched for controlled studies evaluating safety in patients with RA treated with two bDMARDs independently of dose-regimen. Databases used were MEDLINE (via Pubmed), EMBase, Cochrane Library, Scopus, ClinicalTrials.gov, and the WHO International Clinical Trials Registry platform. A meta-analysis was performed between groups on combination therapy and patients on single therapy using random effects model calculating odds ratio (OR) as well as 95% confidence interval (CI). The primary outcome was the rate of serious adverse events (SAEs)., Results: Six studies with a total of 623 patients (410 on combination therapy and 213 on single therapy) were included. Median follow-up was 9.5 months (range 6-12 months). There was a significant increase in SAEs in the combination group (14.9 vs 6.0%, OR 2.51, 95% CI 1.29-4.89, I 2  0%) as well as in total adverse events (94.6 vs 89.1%, OR 2.07, 95% CI 1.11-3.86, I 2  0%). When performing subgroup analysis in patients receiving only full-dose of both bDMARDs there was a significant increase in serious infections (6.7 vs 0.6%, OR 5.58, 95% CI 1.25-24.90, I 2  0%) and the risk of SAEs remained significantly higher (17.1 vs 6.2%, OR 2.72, 95% CI 1.30-5.69, I 2  0%)., Conclusion: Our findings suggest that combination therapy with two bDMARDs in RA appears to increase the risk of SAEs during the first twelve months of treatment., (Copyright © 2018 Elsevier Inc.

Background: Data on the economic consequences of hip and knee osteoarthritis (OA) are scarce. We aimed to estimate the annual direct and indirect costs for patients followed for hip and/or knee OA in the Knee and Hip Osteoarthritis Long term Assessment (KHOALA) cohort., Methods: The KHOALA cohort, set up from 2007 to 2009, is a French multicenter study of 878 individuals with symptomatic knee/hip OA who were 40-75 years old. Resources used were collected annually for 5 years. Costs were assigned by using official sources and expressed in 2018 euros per patient., Results: The mean annual total costs per patient over the 5-year study period were 2,180 ± 5,305€. The mean annual direct medical costs per patient were 2,120 ± 5,275€ and mean annual indirect costs per patient 180 ± 1,735€ for people of working age. Costs increased slightly over the study period. Drugs were the largest cost share, representing over 50% of all direct costs. However, the proportion attributable to OA drugs accounted for only 10.5% of drug costs. The second cost share was hospitalizations; hip and knee prosthetic surgery accounted for 27% of surgery hospitalization costs. Health professional visits were the third cost share, accounting for 3% of direct medical costs. The median costs induced could be as high as 2 billion €/year (IQR 0.7-4.3) in France., Conclusion: Hip and knee OA costs were substantial and increased over the study period in France. However, the costs attributable to OA represented only a small fraction of overall costs., (Copyright © 2019. Published by Elsevier Ltd.)

Introduction: Bariatric surgery is used to treat severe obesity. We aimed to investigate the incidence of clinically significant bone mineral density (BMD) loss at 6 and 12 months after bariatric surgery., Methods: Observational study performed in a specialized center for the treatment of obesity at the University Hospital of Reims, France. Surface BMD was measured by dual x-ray absorptiometry (DEXA). A reduction of > 0.03 g/cm 2 was considered clinically significant., Results: A total of 110 patients were included. A clinically significant reduction in BMD was observed in 62.1% of patients at 6 months, and in 71.6% at 12 months after surgery. No case of osteoporosis was observed. There were four cases of osteopenia and one fracture post-surgery. BMD loss was related by univariate analysis to the reduction in body mass index (BMI) (p < 0.01), weight loss (p < 0.01), fat mass (p < 0.01), and lean mass (p < 0.01). Multivariable analysis found a significant association between the reduction in BMD and the excess weight loss percentage (odds ratio 1.11, 95% confidence interval (1.05-1.18), p < 0.001)., Conclusion: There was a clinically significant reduction in BMD at 6 months after surgery in over 60% of patients undergoing bariatric surgery. BMD loss is persistent over time and predominantly situated at the femoral level, and strongly associated with weight loss. Systematic vitamin and calcium supplementation, as well as follow-up by DEXA scan seems appropriate. Systematic DEXA scan pre- and post-surgery, and annually thereafter until weight has stabilized seems appropriate.

Introduction: The main objective of this work was to assess the maintenance of effectiveness of subcutaneous tocilizumab 6 months after switching from intravenous to subcutaneous formulation in patients with rheumatoid arthritis (RA) in a real-world setting. Secondary objectives aimed to describe the characteristics of patients and disease, the effectiveness at 12 months after switching, the therapeutic maintenance, and to search for predictive factors of switching., Methods: We analyzed all the RA patients of the shared medical file "RIC Nord de France", treated with tocilizumab, switching or not from intravenous to subcutaneous tocilizumab, between April 2015 and January 2016. The primary effectiveness endpoint was the proportion of patients remaining in their DAS28-ESR category remission/low disease activity (LDA) or moving to an inferior DAS28-ESR category at 6 months. Since RoSwitch was an observational study, without randomization, a propensity score was built in a sensitivity analysis to balance on RA and patients' characteristics at inclusion between switching and no-switching groups., Results: An improvement of initial DAS28-ESR category or maintenance in DAS28-ESR remission/LDA at 6 months was shown in 203 of the 285 patients with an evaluation for the primary criterion (71.2%, 95% CI [65.6-76.4%]) without differences between groups (73.3%, 95% CI [63.0-82.1%] vs. 70.3%, 95% CI [63.3-76.6%]). The RoSwitch study showed the maintenance of effectiveness at 6 and 12 months. Similar therapeutic maintenance rates were observed for switch and no-switch patients. No clinical factor was associated with the switch in patients in remission/LDA at inclusion., Conclusions: The RoSwitch study showed the maintenance of effectiveness at 6 months in RA patients switching from intravenous (IV) to subcutaneous (SC) tocilizumab., Funding: Roche SAS and Chugai Pharma France.

Background: The place of disease-modifying osteoarthritis drugs (DMOADs) and intra-articular hyaluronic acid (IAHA) in the therapeutic arsenal for knee osteoarthritis (OA) remains uncertain. Indeed, these treatments have demonstrated symptomatic efficacy but no efficacy for disease modification., Objective: This report reviews the cost effectiveness of IAHA and DMOADs used in the treatment of knee OA., Methods: A systematic literature search of the MEDLINE, Scopus, EMBASE and Cochrane databases was performed independently by two rheumatologists who used the same predefined eligibility criteria to identify relevant articles. Papers without abstracts and in languages other than English or French were excluded. Extracted costs were annualised and converted to 2015 euros (€) using the Consumer Price Index of the relevant countries and the 2013 Purchasing Power Parities between these countries and the European Union average., Results: A total of 95 abstracts were selected, and 13 articles were considered for the review: nine articles on IAHA and four on DMOADs. Only one article directly compared different IAHA compounds. Articles showed substantial heterogeneity in methodological approaches. The incremental cost-effectiveness ratios (ICERs) ranged from €4000 to €57,550 and from €240 to €53,225 per quality-adjusted life-year (QALY) gained for DMOADs and IAHA, respectively., Conclusions: This review highlights substantial heterogeneity between studies, ranging from a cost saving (or dominating) position to very high ICERs, far above the acceptability threshold of €50,000/QALY. Additional research is needed to determine reliable and robust ICER estimates for knee OA therapies.

Objectives: We aimed to investigate the existence of an association between hidrosadenitis suppurativa and spondyloarthritis., Methods: We performed a single-centre, cross-sectional study in patients with hidrosadenitis suppurativa followed in a tertiary care center, and in healthy volunteers without dermatological disease, matched for age (±5years) and gender. For each subject included, clinical examinations, HLA-B27 testing and sacro-iliac MRI were performed in order to diagnose spondyloarthritis according to the Assessment of SpondyloArthritis international Society (ASAS) criteria., Results: In total, 39 subjects were included in each group (70% women in each group, mean age 35.6±11.1 in the hidrosadenitis suppurativa group and 36.0±11.1 in the control group). Eleven (28.2%) patients in the hidrosadenitis suppurativa group were diagnosed with spondyloarthritis (in 4 of these, spondyloarthritis was already previously documented), and in 1 (2.6%) subject in the control group (OR 11.0; 95% CI 4.1-83.3; P=0.02). Axial spondyloarthritis was the most common form of spondyloarthritis, observed in 9/11 patients in the hidrosadenitis suppurativa group, the remainder were peripheral spondyloarthritis. In the hidrosadenitis suppurativa group, only HLA B27 was found to be associated with a diagnosis of spondyloarthritis., Conclusions: Our results indicate that hidrosadenitis suppurativa is significantly associated with an increased risk of spondyloarthritis, independently of age and sex. Patients with hidrosadenitis suppurativa presenting osteoarticular symptoms, specially low back pain or dactylitis, should be monitored for spondyloarthritis., (Copyright © 2017 Société française de rhumatologie.

Objective: Study the therapeutic maintenance, efficacy and reasons for tocilizumab stop in daily practice., Patients and Methods: A monocentric, retrospective study of patients treated for rheumatoid arthritis who received at least one TCZ infusion between January 2009 and December 2015. Therapeutic maintenance was evaluated using the Kaplan-Meier method. The efficacy of TCZ was measured by DAS28 and the EULAR response. Reasons for stopping and new treatment lines were also collected., Results: Of the 88 patients (83% women and 17% men) who were included, the mean age was 54±12.5 years. There were 75% positive rheumatoid factors and 76% positive anti-CCP. The mean duration of the follow-up was 31 months. TCZ was used as monotherapy in 24 patients (27%). Before the introduction of TCZ, the mean DAS28 was 5.07±1.32. The EULAR response at 1 year in patients still under treatment (n=63) was obtained in 59 (93.7%) patients, 46 good responders and 13 moderate responders. Therapeutic maintenance was 82.9%, 72.5%, 68.7% and 57.2%, respectively, at 12, 24, 36 and 54 months. Twenty-eight patients (32%) followed TCZ, 10 for adverse events and 14 for ineffectiveness. Abatacept was the main new therapeutic line., Conclusion: The therapeutic maintenance of TCZ in common practice over a long period of follow-up is similar to pivotal studies. Efficacy data are reassuring in the long-term., (Copyright © 2017 Société française de pharmacologie et de thérapeutique. Published by Elsevier Masson SAS. All rights reserved.)

Objective: The aim was to evaluate the incidence of serious infusion-related reactions (SIRRs) in RA treated by non-TNF-targeted biologics., Methods: We analysed data from three independent prospective registers, namely autoimmunity and rituximab, Orencia (abatacept) and RA (ORA) and Registry RoAcTEmra (tocilizumab), promoted by the French Society of Rheumatology and including patients with RA. SIRRs were defined by an occurrence during or within 24 h of an infusion and requiring discontinuation of treatment. Characteristics of patients with SIRRs were extracted from the electronic database., Results: Among the 4145 patients, SIRRs occurred in 100 patients: 56 patients with the rituximab cohort (2.8% or 0.7/100 patient-years), 15 with the abatacept cohort (1.5% or 0.6/100 patient-years) and 29 with tocilizumab (1.9% or 1/100 patient-years). No fatal SIRR occurred. A previous mild infusion reaction to non-TNF-targeted biologics was observed in a quarter of patients with SIRRs. After pooled multivariate analysis, positive anti-CCP was associated with a higher risk of SIRR (odds ratio = 2.5; 95% CI: 1.01, 6.17). Absence of concomitant treatment with a synthetic DMARD tended to be associated with a higher risk of SIRR (odds ratio = 1.67; 95% CI: 1.00, 2.86)., Conclusion: In daily practice, SIRRs are slightly more frequent than in clinical trials and rarely life threatening. In common practice, serological status (anti-CCP positivity) and absence of concomitant treatment with a synthetic DMARD increase the risk of SIRR., (© The Author 2017.

Objectives: Assess the frequency of paradoxical reactions encountered in daily practice under tocilizumab, using the REGATE (Registry-RoActemra) registry. The secondary objectives were to determine the type of paradoxical reaction and the consequences of these reactions., Methods: The REGATE registry is an independent prospective registry, promoted by the French Society of Rheumatology, consisting of patients treated with tocilizumab for rheumatoid arthritis. The paradoxical reaction was retained if it was a paradoxical precipitation of a condition for which tocilizumab was indicated, if tocilizumab was being used for an alternative indication, and if it appeared after at least one tocilizumab infusion., Results: Among the 1491 patients included with at least one follow-up visit (3429 patient-years), a paradoxical reaction occurred in 9 patients (0.60% of patients; 2.62/1000 patient-years). These were 7 de novo pathologies (3 vasculitis, 3 uveitis, 1 lupus) and 2 exacerbations of pre-existing conditions (1 vasculitis, 1 lupus). Permanent discontinuation of tocilizumab was chosen for 5 patients., Conclusions: In the REGATE registry, the occurrence of paradoxical reactions in patients treated with tocilizumab was rare., (Copyright © 2017 Société française de rhumatologie.

Over 1.5 million individuals suffer from cornea vascularization due to genetic and/or environmental factors, compromising visual acuity and often resulting in blindness. Current treatments of corneal vascularization are limited in efficacy and elicit undesirable effects including, ironically, vision loss. To develop a safe and effective therapy for corneal vascularization, adeno-associated virus (AAV) gene therapy, exploiting a natural immune tolerance mechanism induced by human leukocyte antigen G (HLA-G), was investigated. Self-complementary AAV cassettes containing codon optimized HLA-G1 (transmembrane) or HLA-G5 (soluble) isoforms were validated in vitro. Then, following a corneal intrastromal injection, AAV vector transduction kinetics, using a chimeric AAV capsid, were determined in rabbits. One week following corneal trauma, a single intrastromal injection of scAAV8G9-optHLA-G1 + G5 prevented corneal vascularization, inhibited trauma-induced T-lymphocyte infiltration (some of which were CD8 + ), and dramatically reduced myofibroblast formation compared to control treated eyes. Biodistribution analyses suggested AAV vectors persisted only in the trauma-induced corneas; however, a neutralizing antibody response to the vector capsid was observed inconsistently. The collective data demonstrate the clinical potential of scAAV8G9-optHLA-G to safely and effectively treat corneal vascularization and inhibit fibrosis while alluding to broader roles in ocular surface immunity and allogenic organ transplantation.
