RESUMO
BACKGROUND: In a clinical trial setting, patients with rheumatoid arthritis (RA) taking the Janus kinase inhibitor (JAKi) tofacitinib demonstrated higher adverse events rates compared with those taking the tumour necrosis factor inhibitors (TNFi) adalimumab or etanercept. OBJECTIVE: Compare treatment discontinuations for adverse events (AEs) among second-line therapies in an international real-world RA population. METHODS: Patients initiating JAKi, TNFi or a biological with another mode of action (OMA) from 17 registers participating in the 'JAK-pot' collaboration were included. The primary outcome was the rate of treatment discontinuation due to AEs. We used unadjusted and adjusted cause-specific Cox proportional hazard models to compare treatment discontinuations for AEs among treatment groups by class, but also evaluating separately the specific type of JAKi. RESULTS: Of the 46 913 treatment courses included, 12 523 were JAKi (43% baricitinib, 40% tofacitinib, 15% upadacitinib, 2% filgotinib), 23 391 TNFi and 10 999 OMA. The adjusted cause-specific hazard rate of treatment discontinuation for AEs was similar for TNFi versus JAKi (1.00, 95% CI 0.92 to 1.10) and higher for OMA versus JAKi (1.11, 95% CI 1.01 to 1.23), lower with TNFi compared with tofacitinib (0.81, 95% CI 0.71 to 0.90), but higher for TNFi versus baricitinib (1.15, 95% CI 1.01 to 1.30) and lower for TNFi versus JAKi in patients 65 or older with at least one cardiovascular risk factor (0.79, 95% CI 0.65 to 0.97). CONCLUSION: While JAKi overall were not associated with more treatment discontinuations for AEs, subgroup analyses suggest varying patterns with specific JAKi, such as tofacitinib, compared with TNFi. However, these observations should be interpreted cautiously, given the observational study design.

Musculoskeletal diseases, on the rise, pose a major challenge in French-speaking Switzerland where the shortage of rheumatologists is worsening, due to the aging of practitioners, a scarcity of emerging professionals, and a trend towards part-time work among young doctors. To address this, increasing rheumatology training positions and enhancing general practitioners' training in these pathologies are essential. The adoption of alternative care models, such as monitoring by specialized nurses and greater involvement of physiotherapists, should be considered. This evolution is crucial for patients, whose quality of life and health depend on the accessibility and effectiveness of adequate care. Therefore, concerted action is indispensable to ensure a sustainable and effective future for rheumatology in French-speaking Switzerland.
Les maladies musculosquelettiques, en augmentation, posent un défi majeur en Romandie, où la pénurie de rhumatologues s'aggrave en raison du vieillissement des praticiens, du manque de relève et de la tendance au travail partiel chez les jeunes médecins. Pour y faire face, augmenter les postes de formation en rhumatologie et renforcer la formation des généralistes dans les pathologies concernées est essentiel. L'adoption de modèles de soins alternatifs, comme le suivi par des infirmiers spécialisés, et une plus grande implication des physiothérapeutes sont à envisager. Cette évolution est cruciale pour les patients, dont la qualité de vie et la santé dépendent de l'efficacité et de l'accessibilité à des soins adéquats. Une action concertée est donc indispensable pour assurer un avenir durable et efficace de la rhumatologie en Romandie.

OBJECTIVES: The expanded therapeutic arsenal in rheumatoid arthritis (RA) raises new clinical questions. The objective of this study is to compare the effectiveness of cycling Janus kinase inhibitors (JAKi) with switching to biologic disease-modifying antirheumatic drug (bDMARD) in patients with RA after failure to the first JAKi. METHODS: This is a nested cohort study within data pooled from an international collaboration of 17 national registries (JAK-pot collaboration). Data from patients with RA with JAKi treatment failure and who were subsequently treated with either a second JAKi or with a bDMARD were prospectively collected. Differences in drug retention rates after second treatment initiation were assessed by log-rank test and Cox regression analysis adjusting for potential confounders. Change in Clinical Disease Activity Index (CDAI) over time was estimated using a linear regression model, adjusting for confounders. RESULTS: 365 cycling and 1635 switching patients were studied. Cyclers were older and received a higher number of previous bDMARDs. Both strategies showed similar observed retention rates after 2 years of follow-up. However, adjusted analysis revealed that cycling was associated with higher retention (p=0.04). Among cyclers, when the first JAKi was discontinued due to an adverse event (AE), it was more likely that the second JAKi would also be stopped due to an AE. Improvement in CDAI over time was similar in both strategies. CONCLUSIONS: After failing the first JAKi, cycling JAKi and switching to a bDMARD appear to have similar effectiveness. Caution is advised if an AE was the reason to stop the first JAKi.

OBJECTIVES: To develop EULAR recommendations for screening and prophylaxis of chronic and opportunistic infections in patients with autoimmune inflammatory rheumatic diseases (AIIRD). METHODS: An international Task Force (TF) (22 members/15 countries) formulated recommendations, supported by systematic literature review findings. Level of evidence and grade of recommendation were assigned for each recommendation. Level of agreement was provided anonymously by each TF member. RESULTS: Four overarching principles (OAP) and eight recommendations were developed. The OAPs highlight the need for infections to be discussed with patients and with other medical specialties, in accordance with national regulations. In addition to biologic/targeted synthetic disease-modifying antirheumatic drugs (DMARDs) for which screening for latent tuberculosis (TB) should be performed, screening could be considered also before conventional synthetic DMARDs, glucocorticoids and immunosuppressants. Interferon gamma release assay should be preferred over tuberculin skin test, where available. Hepatitis B (HBV) antiviral treatment should be guided by HBV status defined prior to starting antirheumatic drugs. All patients positive for hepatitis-C-RNA should be referred for antiviral treatment. Also, patients who are non-immune to varicella zoster virus should be informed about the availability of postexposure prophylaxis should they have contact with this pathogen. Prophylaxis against Pneumocystis jirovecii seems to be beneficial in patients treated with daily doses >15-30 mg of prednisolone or equivalent for >2-4 weeks. CONCLUSIONS: These recommendations provide guidance on the screening and prevention of chronic and opportunistic infections. Their adoption in clinical practice is recommended to standardise and optimise care to reduce the burden of opportunistic infections in people living with AIIRD.

OBJECTIVES: To provide an update of the EULAR rheumatoid arthritis (RA) management recommendations addressing the most recent developments in the field. METHODS: An international task force was formed and solicited three systematic literature research activities on safety and efficacy of disease-modifying antirheumatic drugs (DMARDs) and glucocorticoids (GCs). The new evidence was discussed in light of the last update from 2019. A predefined voting process was applied to each overarching principle and recommendation. Levels of evidence and strengths of recommendation were assigned to and participants finally voted on the level of agreement with each item. RESULTS: The task force agreed on 5 overarching principles and 11 recommendations concerning use of conventional synthetic (cs) DMARDs (methotrexate (MTX), leflunomide, sulfasalazine); GCs; biological (b) DMARDs (tumour necrosis factor inhibitors (adalimumab, certolizumab pegol, etanercept, golimumab, infliximab including biosimilars), abatacept, rituximab, tocilizumab, sarilumab and targeted synthetic (ts) DMARDs, namely the Janus kinase inhibitors tofacitinib, baricitinib, filgotinib, upadacitinib. Guidance on monotherapy, combination therapy, treatment strategies (treat-to-target) and tapering in sustained clinical remission is provided. Safety aspects, including risk of major cardiovascular events (MACEs) and malignancies, costs and sequencing of b/tsDMARDs were all considered. Initially, MTX plus GCs is recommended and on insufficient response to this therapy within 3-6 months, treatment should be based on stratification according to risk factors; With poor prognostic factors (presence of autoantibodies, high disease activity, early erosions or failure of two csDMARDs), any bDMARD should be added to the csDMARD; after careful consideration of risks of MACEs, malignancies and/or thromboembolic events tsDMARDs may also be considered in this phase. If the first bDMARD (or tsDMARD) fails, any other bDMARD (from another or the same class) or tsDMARD (considering risks) is recommended. With sustained remission, DMARDs may be tapered but should not be stopped. Levels of evidence and levels of agreement were high for most recommendations. CONCLUSIONS: These updated EULAR recommendations provide consensus on RA management including safety, effectiveness and cost.

OBJECTIVES: This study aimed to evaluate if and how the incidence of serious infection (SI) and active tuberculosis (TB) differ among seven biological disease-modifying antirheumatic drugs (bDMARDs) in patients with rheumatoid arthritis (RA) considering the line of therapy. METHODS: Patients with RA from the British Society for Rheumatology Biologics Register-RA cohort who initiated etanercept, certolizumab, infliximab, adalimumab, abatacept, rituximab, or tocilizumab from the first to fifth line of therapy were included. Follow-up extended up to three years. Primary outcome was SI, secondary outcome was TB. Event rates were calculated and compared using Cox proportional-hazards, controlling for confounding with inverse probability of treatment weights. Comparisons were made overall and stratified by line of therapy. Sensitivity analysis restricted to all treatment courses from 2009 (tocilizumab availability) until end of study (2018). RESULTS: Among 33 897 treatment courses (62 513 patient-years) the incidence of SI was 4.4/100 patient-years (95%CI 4.2-4.5). After adjustment, hazards ratios (HR) of SI were slightly higher with adalimumab and infliximab compared with etanercept. However, no clear pattern was observed when stratifying by line of therapy, in terms of incidence rate or hazards ratio. Sensitivity analyses showed similar HR among these treatments. Regarding TB, all 49 cases occurred during the first three lines of treatment and rarely since 2009. CONCLUSION: The risk of serious infections does not appear to be influenced by the line of therapy in patients with RA. However, the risk of tuberculosis seems to be more frequent during the initial lines of treatment or prior to 2009.
RESUMO
OBJECTIVES: To assess the relationship between self-reported and serologic evidence of prior chlamydial infection, rheumatoid arthritis (RA)-related autoantibodies and risk of RA-development. METHODS: This is a nested study within a prospective Swiss-based cohort including all first-degree relatives of RA patients (RA-FDR) who answered a question on past chlamydial infections. Primary outcome was systemic autoimmunity associated with RA (RA-autoimmunity) defined as positivity for anti-citrullinated peptide antibodies (ACPA) and/or rheumatoid factor (RF). Secondary outcomes were high levels of RA-autoimmunity, RA-associated symptoms and RA-autoimmunity, and subsequent seropositive RA diagnosis. We conducted a nested case-control analysis by measuring the serological status against Chlamydia trachomatis' major outer membrane protein. We replicated our analysis in an independent United States-based RA-FDR cohort. RESULTS: Among 1231 RA-FDRs, 168 (13.6%) developed RA-autoimmunity. Prevalence of self-reported chlamydial infection was significantly higher in individuals with RA-autoimmunity compared with controls (17.9% vs 9.8%, OR = 2.00, 95%CI: 1.27-3.09, p < 0.01). This association remained significant after adjustments (OR = 1.91, 95%CI: 1.20-2.95). Stronger effect sizes were observed in later stages of RA development. There was a similar trend between a positive C. trachomatis serology and high levels of RA-autoimmunity (OR = 3.05, 95% CI: 1.10-8.46, p= 0.032). In the replication cohort, there were significant associations between chlamydial infection and RF positivity and incident RA, but not anti-CCP positivity. CONCLUSIONS: Self-reported chlamydial infections are associated with elevated RA-autoimmunity in at risk individuals. The differing association of chlamydial infections and ACPA/RF between cohorts will need to be explored in future studies but is consistent with a role of mucosal origin of RA-related autoimmunity.
RESUMO
Rheumatoid arthritis (RA) is a common chronic autoimmune inflammatory disease, primarily affecting the joints. Its activity is subject to exacerbations called flares. These RA flares are linked to cardiovascular, functional and radiological complications. The mechanisms behind these flares are still poorly understood. There is currently no reliable biomarker for the diagnosis of the flares. Diagnostic scores have been developed for research purposes but their application in clinical practice is not yet clear. The therapeutic approach includes acute treatment of the flare with corticosteroids and evaluation of the need for intensification of background therapy.
La polyarthrite rhumatoïde (PR) est une maladie inflammatoire chronique auto-immune fréquente, touchant principalement les articulations, dont l'activité peut être sujette à des exacerbations appelées « poussées ¼. Ces dernières sont liées à des complications cardiovasculaires, fonctionnelles et radiologiques. Les mécanismes à l'origine de ces poussées sont encore mal compris. Il n'existe pas à l'heure actuelle de biomarqueur fiable permettant de diagnostiquer les poussées. Des scores à but diagnostic ont été développés pour la recherche, mais leur application en clinique n'est pas encore claire. L'attitude thérapeutique comprend un traitement aigu de la poussée par une corticothérapie ainsi qu'une évaluation systématique de l'indication à une intensification du traitement de fond.

In rheumatology, this year has seen an expansion of knowledge about the treatment of rheumatoid arthritis, with the availability of results from randomized trials evaluating a new molecule targeting IL-6, and regarding the safety profile of tofacitinib compared to TNF-alpha inhibitors. Interesting data on the outcome of pregnancy in patients with spondylarthritis have also been published. New molecules and different treatment strategies have shown promising results in psoriatic arthritis and systemic lupus erythematosus. The utility of botulinum toxin A injections for Raynaud's phenomenon and the efficacy of transplantation of autologous adipose-derived regenerative cells for the treatment of hand dysfunctions have been questioned by 2 randomized controlled trials of patients with systemic sclerosis.
Cette année a vu un approfondissement des connaissances sur le traitement de la polyarthrite rhumatoïde, avec la publication de résultats d'essais randomisés évaluant une nouvelle molécule ciblant l'IL-6 et le profil de sécurité du tofacitinib par rapport aux inhibiteurs du TNF-alpha. Des données intéressantes sur l'issue de la grossesse chez les patientes atteintes de spondylarthrite ont également été publiées. De nouvelles stratégies de traitement ont donné des résultats prometteurs dans le rhumatisme psoriasique et le lupus érythémateux systémique. L'utilité des injections de toxine botulique A pour le phénomène de Raynaud et l'efficacité de la transplantation de cellules régénératrices adipeuses autologues pour le traitement de dysfonctions de la main ont été remises en question par deux études dans la sclérose systémique.

Gout is a common complication occurring among inpatients, as factors affecting urate levels in blood and tissues are often modified by acute conditions. The control of chronic uricemia within recommended target values helps reduce the risk of flares. Joint aspiration is the gold standard for diagnosis, but ultrasound and dual-energy CT scan are reasonable alternatives. Acute and chronic treatments do not differ from those provided in outpatient care, although the increased prevalence of organ failures often require treatment adjustments. Active patient engagement, including therapeutic education during hospitalization, is essential for long-term disease control.
Lors d'un séjour hospitalier, les facteurs impactant la concentration sanguine et tissulaire d'urate sont souvent modifiés, augmentant le risque d'une crise de goutte. Le maintien de l'uricémie dans les cibles reconnues grâce à la poursuite des traitements contribue à réduire ce risque. La ponction articulaire est la méthode de référence pour établir le diagnostic, mais l'ultrason et le scanner à double énergie sont des alternatives fiables pour diagnostiquer une goutte. Les traitements aigu et chronique ne diffèrent pas de ceux pratiqués en ambulatoire, mais la fréquence augmentée d'insuffisances d'organes peut nécessiter l'adaptation des traitements. Pour assurer un contrôle de la maladie sur le long terme, il est essentiel d'impliquer le patient dans sa prise en charge, notamment par l'éducation thérapeutique dispensée pendant l'hospitalisation.

BACKGROUND: Patients treated with anti-CD20 therapy are particularly at risk of developing severe coronavirus disease 2019 (COVID-19); however, little is known regarding COVID-19 vaccine effectiveness in this population. METHODS: This prospective observational cohort study assesses humoral and T-cell responses after vaccination with 2 doses of mRNA-based COVID-19 vaccines in patients treated with rituximab for rheumatic diseases or ocrelizumab for multiple sclerosis (nâ =â 37), compared to immunocompetent individuals (nâ =â 22). RESULTS: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-specific antibodies were detectable in only 69.4% of patients and at levels that were significantly lower compared to controls who all seroconverted. In contrast to antibodies, Spike (S)-specific CD4â T cells were equally detected in immunocompetent and anti-CD20 treated patients (85-90%) and mostly of a Th1 phenotype. Response rates of S-specific CD8â T cells were higher in ocrelizumab (96.2%) and rituximab-treated patients (81.8%) as compared to controls (66.7%). S-specific CD4â and CD8â T cells were polyfunctional but expressed more effector molecules in patients than in controls. During follow-up, 3 MS patients without SARS-CoV-2-specific antibody response had a mild breakthrough infection. One of them had no detectable S-specific T cells after vaccination. CONCLUSIONS: Our study suggests that patients on anti-CD20 treatment are able to mount potent T-cell responses to mRNA COVID-19 vaccines, despite impaired humoral responses. This could play an important role in the reduction of complications of severe COVID-19.

BACKGROUND: Persistent symptoms of SARS-CoV-2 are prevalent weeks to months following the infection. To date, it is difficult to disentangle the direct from the indirect effects of SARS-CoV-2, including lockdown, social, and economic factors. OBJECTIVE: The study aims to characterize the prevalence of symptoms, functional capacity, and quality of life at 12 months in outpatient symptomatic individuals tested positive for SARS-CoV-2 compared to individuals tested negative. METHODS: From 23 April to 27 July 2021, outpatient symptomatic individuals tested for SARS-CoV-2 at the Geneva University Hospitals were followed up 12 months after their test date. RESULTS: At 12 months, out of the 1447 participants (mean age 45.2 years, 61.2% women), 33.4% reported residual mild to moderate symptoms following SARS-CoV-2 infection compared to 6.5% in the control group. Symptoms included fatigue (16% vs. 3.1%), dyspnea (8.9% vs. 1.1%), headache (9.8% vs. 1.7%), insomnia (8.9% vs. 2.7%), and difficulty concentrating (7.4% vs. 2.5%). When compared to the control group, 30.5% of SARS-CoV-2 positive individuals reported functional impairment at 12 months versus 6.6%. SARS-CoV-2 infection was associated with the persistence of symptoms (adjusted odds ratio [aOR] 4.1; 2.60-6.83) and functional impairment (aOR 3.54; 2.16-5.80) overall, and in subgroups of women, men, individuals younger than 40 years, those between 40-59 years, and in individuals with no past medical or psychiatric history. CONCLUSION: SARS-CoV-2 infection leads to persistent symptoms over several months, including in young healthy individuals, in addition to the pandemic effects, and potentially more than other common respiratory infections. Symptoms impact functional capacity up to 12 months post infection.

OBJECTIVES: To assess the performance of statistical methods used to compare the effectiveness between drugs in an observational setting in the presence of attrition. METHODS: In this simulation study, we compared the estimations of low disease activity (LDA) at 1 year produced by complete case analysis (CC), last observation carried forward (LOCF), LUNDEX, non-responder imputation (NRI), inverse probability weighting (IPW) and multiple imputations of the outcome. All methods were adjusted for confounders. The reasons to stop the treatments were included in the multiple imputation method (confounder-adjusted response rate with attrition correction, CARRAC) and were either included (IPW2) or not (IPW1) in the IPW method. A realistic simulation data set was generated from a real-world data collection. The amount of missing data caused by attrition and its dependence on the 'true' value of the data missing were varied to assess the robustness of each method to these changes. RESULTS: LUNDEX and NRI strongly underestimated the absolute LDA difference between two treatments, and their estimates were highly sensitive to the amount of attrition. IPW1 and CC overestimated the absolute LDA difference between the two treatments and the overestimation increased with increasing attrition or when missingness depended on disease activity at 1 year. IPW2 and CARRAC produced unbiased estimations, but IPW2 had a greater sensitivity to the missing pattern of data and the amount of attrition than CARRAC. CONCLUSIONS: Only multiple imputation and IPW2, which considered both confounding and treatment cessation reasons, produced accurate comparative effectiveness estimates.

BACKGROUND: Comparing treatment effectiveness over time in observational settings is hampered by several major threats, among them confounding and attrition bias. OBJECTIVES: To develop European Alliance of Associations for Rheumatology (EULAR) points to consider (PtC) when analysing and reporting comparative effectiveness research using observational data in rheumatology. METHODS: The PtC were developed using a three-step process according to the EULAR Standard Operating Procedures. Based on a systematic review of methods currently used in comparative effectiveness studies, the PtC were formulated through two in-person meetings of a multidisciplinary task force and a two-round online Delphi, using expert opinion and a simulation study. Finally, feedback from a larger audience was used to refine the PtC. Mean levels of agreement among the task force were calculated. RESULTS: Three overarching principles and 10 PtC were formulated, addressing, in particular, potential biases relating to attrition or confounding by indication. Building on Strengthening the Reporting of Observational Studies in Epidemiology guidelines, these PtC insist on the definition of the baseline for analysis and treatment effectiveness. They also focus on the reasons for stopping treatment as an important consideration when assessing effectiveness. Finally, the PtC recommend providing key information on missingness patterns. CONCLUSION: To improve the reliability of an increasing number of real-world comparative effectiveness studies in rheumatology, special attention is required to reduce potential biases. Adherence to clear recommendations for the analysis and reporting of observational comparative effectiveness studies will improve the trustworthiness of their results.

BACKGROUND: JAK-inhibitors (JAKi), recently approved in rheumatoid arthritis (RA), have changed the landscape of treatment choices. We aimed to compare the effectiveness of four current second-line therapies of RA with different modes of action, since JAKi approval, in an international collaboration of 19 registers. METHODS: In this observational cohort study, patients initiating tumour necrosis factor inhibitors (TNFi), interleukin-6 inhibitors (IL-6i), abatacept (ABA) or JAKi were included. We compared the effectiveness of these treatments in terms of drug discontinuation and Clinical Disease Activity Index (CDAI) response rates at 1 year. Analyses were adjusted for patient, disease and treatment characteristics, including lines of therapy and accounted for competing risk. RESULTS: We included 31 846 treatment courses: 17 522 TNFi, 2775 ABA, 3863 IL-6i and 7686 JAKi. Adjusted analyses of overall discontinuation were similar across all treatments. The main single reason of stopping treatment was ineffectiveness. Compared with TNFi, JAKi were less often discontinued for ineffectiveness (adjusted HR (aHR) 0.75, 95% CI 0.67 to 0.83), as was IL-6i (aHR 0.76, 95% CI 0.67 to 0.85) and more often for adverse events (aHR 1.16, 95% CI 1.03 to 1.33). Adjusted CDAI response rates at 1 year were similar between TNFi, JAKi and IL-6i and slightly lower for ABA. CONCLUSION: The adjusted overall drug discontinuation and 1 year response rates of JAKi and IL-6i were similar to those observed with TNFi. Compared with TNFi, JAKi were more often discontinued for adverse events and less for ineffectiveness, as were IL-6i.

OBJECTIVE: To estimate the extent of and the reasons for ineligibility in randomized controlled trials (RCTs) of SSc patients included in the EUSTAR database, and to determine the association between patient's features and generalizability of study results. METHODS: We searched Clinicaltrials.gov for all records on interventional SSc-RCTs registered from January 2013 to January 2018. Two reviewers selected studies, and information on the main trial features were retrieved. Data from 8046 patients having a visit in the EUSTAR database since 2013 were used to check patient's eligibility. The proportion of potentially eligible patients per trial, and the risk factors for ineligibility were analysed. Complete-, worst- and best-case analyses were performed. RESULTS: Of the 37 RCTs included, 43% were conducted in Europe, 35% were industry-funded, and 87% investigated pharmacological treatments. Ninety-one percent of 8046 patients included could have participated in at least one RCT. In complete-case analysis, the median [range] proportion of eligible patients having the main organ complication targeted by each study was 60% [10-100] in the overall sample of trials, ranging from 50% [32-79] for trials on skin fibrosis to 90% [34-77] for those targeting RP. Among the criteria checked, treatment- and safety-related but not demographic were the main barriers to patient's recruitment. Older age, absence of RP, and lower mRSS were independently associated with the failure to fulfill criteria for any of the included studies. CONCLUSIONS: Patient's representativeness in SSc-RCTs is highly variable and is driven more by treatment- and safety-related rather than demographic criteria.

Patients with inflammatory rheumatologic diseases are at increased risk for infectious complications, including SARS-CoV-2, which represent one of the leading causes of death in this population. This risk is due to both the numerous comorbidities of this patient's group and the immunosuppressive therapies they receive. Vaccination reduces the incidence, complications, and mortality from infections. For patients receiving immunosuppressors, exacerbation of underlying diseases is rarely observed after immunization and only live-attenuated vaccines are contraindicated. A vaccination history and updated vaccination plan should be part of the clinical follow-up of patients with inflammatory rheumatism.
Les patients souffrant de maladies rhumatologiques inflammatoires sont plus à risque de complications infectieuses, y compris avec le SARS-CoV-2, qui représentent l'une des premières causes de mortalité dans cette population. Ce risque est attribuable à la fois aux nombreuses comorbidités de ces patients et aux thérapies immunosuppressives qu'ils reçoivent. La vaccination diminue l'incidence, les complications et la mortalité dues aux infections. Pour les patients recevant des immunosuppresseurs, une exacerbation significative des maladies sous-jacentes n'est qu'exception nellement observée après vaccination et seuls les vaccins vivants atténués sont en principe contre-indiqués.

In rheumatology, this year has seen an expansion of knowledge about the effects of COVID and the vaccine response in patients with autoimmune diseases, but also a re-examination of the usual doses of glucocorticoids in vasculitides and new treatments strategies for diseases such as systemic lupus erythematosus, spondylarthritis and rheumatoid arthritis. New criteria for imaging assessment in spondylarthritis and new management guidelines for patients with low back pain have also been proposed.
En rhumatologie, dans les nouveautés que nous avons choisi de mettre en avant, cette année a vu l'élargissement des connaissances sur le Covid et la réponse vaccinale chez les patients avec maladies autoimmunes, la remise en question des doses habituelles des corticostéroïdes dans les vascularites et la possibilité de nouveaux traitements ou stratégies de prise en charge, dans le lupus érythémateux systémique, les spondylarthrites et la polyarthrite rhumatoïde. De nouveaux critères pour l'évaluation de l'imagerie des spondylarthrites ont aussi été proposés et des précisions quant au type de prise en charge nécessaire pour les patients lombalgiques ont également été apportées.

OBJECTIVES: RF and ACPA are used as diagnostic tools and their presence has been associated with clinical response to some biologic DMARDs (bDMARDs) in RA. This study compared the impact of seropositivity on drug discontinuation and effectiveness of bDMARDs in patients with RA, using head-to-head comparisons in a real-world setting. METHODS: We conducted a pooled analysis of 16 observational RA registries. Inclusion criteria were a diagnosis of RA, initiation of treatment with rituximab (RTX), abatacept (ABA), tocilizumab (TCZ) or TNF inhibitors (TNFis) and available information on RF and/or ACPA status. Drug discontinuation was analysed using Cox regression, including drug, seropositivity, their interaction, adjusting for concomitant and past treatments and patient and disease characteristics and accounting for country and calendar year of bDMARD initiation. Effectiveness was analysed using the Clinical Disease Activity Index evolution over time. RESULTS: Among the 27 583 eligible patients, the association of seropositivity with drug discontinuation differed across bDMARDs (P for interaction <0.001). The adjusted hazard ratios for seropositive compared with seronegative patients were 1.01 (95% CI 0.95, 1.07) for TNFis, 0.89 (0.78, 1.02)] for TCZ, 0.80 (0.72, 0.88) for ABA and 0.70 (0.59, 0.84) for RTX. Adjusted differences in remission and low disease activity rates between seropositive and seronegative patients followed the same pattern, with no difference in TNFis, a small difference in TCZ, a larger difference in ABA and the largest difference in RTX (Lundex remission difference +5.9%, low disease activity difference +11.6%). CONCLUSION: Seropositivity was associated with increased effectiveness of non-TNFi bDMARDs, especially RTX and ABA, but not TNFis.
