RESUMO
OBJECTIVE: To evaluate the relevance of the Rheumatoid Arthritis Impact of Disease (RAID) score as a disease activity marker of rheumatoid arthritis (RA) in a teleconsultation setting. METHODS: A prospective, observational, 24-month, single-center study involving patients with RA who underwent teleconsultations was performed. The RAID score was sent to all patients by email and completed the day before the scheduled session. The RAID questionnaire was also completed just prior to the next scheduled face-to-face consultation. The same physician performed teleconsultation/in-person consultations and was unaware of the RAID results. RESULTS: We included 70 patients (mean age 50 [SD 14] yrs, mean disease duration 10 [SD 9] yrs). The RAID score correlated with the following items: patient global assessment (r 0.55, P < 0.001), patient-reported swollen joint count (r 0.50, P < 0.001), and Disease Activity Score in 28 joints based on C-reactive protein (DAS28-CRP) calculated with patient self-reported tender/swollen joints (r 0.74, P < 0.001). The RAID score completed during the next face-to-face consultation for 45 patients also correlated with the DAS28-CRP performed by the clinician (r 0.65, P < 0.001). A RAID score > 2 was associated with the best combination of sensitivity (94%) and specificity (43%) for the indication of rapid in-person consultation because of insufficiently controlled disease activity, with an area under the curve of 0.74. All 23 patients with RAID < 2 had no intercurrent flares; overall physician global assessment was 1.6 of 10 (SD 1.4), DAS28-CRP 1.5 (SD 0.2), and CRP 1.8 (SD 1.4) mg/L. CONCLUSION: Our findings reinforce the RAID score as a valuable tool in teleconsultation, exhibiting a good correlation with disease activity variables. Using a RAID score threshold of 2 during teleconsultations could distinguish patients with good disease control and those with the potential need for an in-person visit.
RESUMO
Therapeutic monoclonal antibodies have been successful in protecting vulnerable populations against SARS-CoV-2. However, their effectiveness has been hampered by the emergence of new variants. To adapt the therapeutic landscape, health authorities have based their recommendations mostly on in vitro neutralization tests. However, these do not provide a reliable understanding of the changes in the dose-effect relationship and how they may translate into clinical efficacy. Taking the example of EvusheldTM (AZD7442), we aimed to investigate how in vivo data can provide critical quantitative results and project clinical effectiveness. We used the Golden Syrian hamster model to estimate 90â¯% effective concentrations (EC90) of AZD7442 in vivo against SARS-CoV-2 Omicron BA.1, BA.2 and BA.5 variants. While our in vivo results confirmed the partial loss of AZD7442 activity for BA.1 and BA.2, they showed a much greater loss of efficacy against BA.5 than that obtained in vitro. We analyzed in vivo EC90s in perspective with antibody levels measured in a cohort of immunocompromised patients who received 300â¯mg of AZD7442. We found that a substantial proportion of patients had serum levels of anti-SARS-CoV-2 spike protein IgG above the estimated in vivo EC90 for BA.1 and BA.2 (21â¯% and 92â¯% after 1 month, respectively), but not for BA.5. These findings suggest that AZD7442 is likely to retain clinical efficacy against BA.2 and BA.1, but not against BA.5. Overall, the present study illustrates the importance of complementing in vitro investigations by preclinical studies in animal models to help predict the efficacy of monoclonal antibodies in humans.

Objective: Systemic sclerosis is an autoimmune disease characterized by fibrosis of the skin and internal organs including the lung. Mucosal-associated invariant T cells are innate-like T lymphocytes able to produce various cytokines and cytotoxic mediators such as granzyme B. A large body of evidence supports a role of mucosal-associated invariant T cells in autoimmune disease but more recent reports suggest also a potential role in fibrotic conditions. Therefore, we herein addressed the question as whether mucosal-associated invariant T cells may have an altered profile in systemic sclerosis. Methods: Mucosal-associated invariant T cell frequency was analyzed by flow cytometry, using fresh peripheral blood from 74 consecutive systemic sclerosis patients who were compared to 44 healthy donors. In addition, in-depth mucosal-associated invariant T cell phenotype and function were analyzed in unselected 29 women with systemic sclerosis who were compared to 23 healthy women donors. Results: Proportion of circulating mucosal-associated invariant T cells was significantly reduced by 68% in systemic sclerosis compared to healthy donors (0.78% in systemic sclerosis vs 2.5%, p < 0.0001). Within systemic sclerosis subsets, mucosal-associated invariant T cells were reduced in patients with interstitial lung disease (systemic sclerosis-interstitial lung disease) (0.56% vs 0.96% in patients without interstitial lung disease, p = 0.04). Moreover, in systemic sclerosis patients, mucosal-associated invariant T cells displayed an activated phenotype indicated by markedly increased CD69+ mucosal-associated invariant T cell frequency (20% mucosal-associated invariant T cell CD69+ compared to 9.4% in healthy donors, p = 0.0014). Interestingly, mucosal-associated invariant T cells from systemic sclerosis-interstitial lung disease patients had a more pronounced altered phenotype compared to systemic sclerosis without interstitial lung disease with a correlation between mucosal-associated invariant T cells expressing CCR6+ and mucosal-associated invariant T cell frequency (r = 0.8, p = 0.006). Conclusion: Circulating mucosal-associated invariant T cells were reduced and exhibited an activated phenotype in systemic sclerosis patients. This peripheral mucosal-associated invariant T cell deficiency may be related to enhanced apoptosis and/or homing in inflamed tissue, particularly in systemic sclerosis-interstitial lung disease patients.

OBJECTIVE: Our goal was to study the tolerance and efficacy of two B cell depletion strategies, including one with CD19-targeted chimeric antigen receptor (CAR) T cells, in a preclinical model mimicking the severe lung damages observed in systemic sclerosis. METHODS: B cell depletion strategies were evaluated in the Fra-2 transgenic (Tg) mouse model. We considered a first group of 16 untreated mice, a second group of 15 mice receiving a single dose of anti-CD20 monoclonal antibody (mAb), and a third group of 8 mice receiving CD19-targeted CAR-T cells in combination with anti-CD20 monoclonal antibody. After six weeks of clinical evaluation, different validated markers of inflammation, lung fibrosis, and pulmonary vascular remodeling were assessed. RESULTS: CD19-targeted CAR-T cells infusion in combination with anti-CD20 mAb resulted in a deeper B cell depletion than anti-CD20 mAb alone in the peripheral blood and lesional lungs of Fra-2 Tg mice. CAR-T cell infusion worsened the clinical score and increased mortality in Fra-2 Tg mice. In line with the above findings, CAR-T cell infusion significantly increased lung collagen content, the histological fibrosis score, and right ventricular systolic pressure. CAR-T cells accumulated in lesional lungs and promoted T activation and inflammatory cytokine production. Treatment with anti-CD20 mAb in monotherapy had no impact on lung inflammation-driven fibrosis and pulmonary hypertension. CONCLUSION: B cell therapies failed to show efficacy in the Fra2 Tg mice. The exacerbated Fra-2 lung inflammatory burden stimulated accumulation and expansion of activated CD19-targeted CAR-T cells, secondarily inducing T cell activation and systemic inflammation, finally leading to disease worsening.

OBJECTIVE: Monoclonal gammopathy of undetermined significance (MGUS) is common, but there are scarce data regarding the effect of DMARDs on this premalignant condition. We aimed to evaluate the impact of JAK inhibitors (JAKis) on MGUS when initiated for an active rheumatic disease. METHODS: Patients with monoclonal abnormality prior to JAKi initiation for an active rheumatic disease were identified through the MAJIK-SFR Registry, a French multicentre prospective study. Clinical and biological data were collected using a standardized case report form. RESULTS: Twenty patients were identified with a mean age of 65 years and a diagnosis of RA (n = 15), PsA (n = 3), and axial SpA (n = 2). The JAKi prescribed was baricitinib (n = 9), tofacitinib (n = 6) or upadacitinib (n = 5), with a mean duration of 15.5 months. Seventeen patients had individualized serum monoclonal protein (IgG kappa n = 9; IgG lambda n = 4; IgM kappa n = 3; IgA lambda n = 1) ranging from 0.16 to 2.3 g/dl, and three patients did not have an initial measurable spike but they had a positive serum immunofixation. With a follow-up of 4-28 months, the serum monoclonal protein level decreased in 8 of 17 patients (47%), remained stable in 8 patients (47%) and increased in 1 patient (6%). The maximal decrease observed was an initial IgG kappa of 2.3 g/dl, decreasing to 0.2 g/dl at month 14. CONCLUSION: This study provides reassuring and promising data on MGUS evolution in patients treated with JAKis for rheumatic diseases, which may guide the choice of treatment in patients with both conditions.

OBJECTIVE: To validate the predictive value of the DAS28 γ-glutamyl transferase (DAS28-γGT) for the occurrence of major cardiovascular (CV) events (MACE) in the 'Etude et Suivi des Polyarthrites Indifférenciées Récentes' ESPOIR cohort. METHODS: Analysis of 13-year outcome from the ESPOIR cohort. RA patients with missing data for baseline γGT activity and those not followed-up to 1 year were excluded. Baseline DAS28-γGT was calculated using the following formula: 0.56*âTJ-28 + 0.28 * âSJ-28 + 2*ln(γGT) + 0.014 * GH. Our primary outcome was the merit of the DAS28-γGT in predicting the occurrence of MACE. RESULTS: Among the 696 patients [536 women, mean (s.d.) age of 49 (12) years], 34 MACE were recorded, with a mean time to event of 71 (44) months. Receiver operating characteristic curve analysis indicated that a DAS28-γGT >9.4 had the best sensitivity and specificity for the diagnosis of MACE during the observation period. DAS28-γGT >9.4 was predictive of the occurrence of MACE, with a hazard ratio (HR) of 3.11 (95% CI 1.41, 5.43). Multivariate Cox analyses confirmed higher DAS28-γGT (HR 2.44, 95% CI 1.05, 5.64) together with age (HR 1.04, 95% CI 1.01, 1.07) and diabetes mellitus (HR 4.12, 95% CI 1.55, 10.95) as independent predictors of MACE. There was a dose effect of the DAS28-γGT for MACE-risk prediction, which was in line with the application of the Framingham risk score. CONCLUSION: The DAS28-γGT was identified in this large prospective cohort as an independent predictor of MACE in patients with RA. The DAS28-γGT is a simple and useful tool to evaluate CV risk in routine and warn the clinician about the CV risk burden in patients with RA.

Background: Fibromyalgia is a prevalent condition affecting 1-2% of the general population and can result in significant disability. Physicians and patients frequently encounter challenges in managing this condition. Aim: The aim of this study was to explore novel management approaches through a qualitative analysis of the doctor-patient relationship. Design and setting: Telephonic interviews were conducted with fibromyalgia patients to investigate their healthcare experiences. Methods: Qualitative analysis was performed on patients' narratives using interpretative phenomenological analysis, a methodology that delves into each individual's subjectivity. Results: A total of 19 adult patients with fibromyalgia, primarily middle-aged women (84% women, mean age 49.8 years), recruited from two university centers in Paris, were included in the study. The narratives of participants revealed substantial suffering and considerable functional impairment, which is paradoxical for a condition often considered benign. They reported an ongoing sense of loss of control, exacerbated by an imbalanced patient-doctor relationship. Patients constantly feared not being heard or believed, and they frequently sought attention from their caregivers. Most participants displayed significant ambivalence toward the nature of their condition and actively sought causal links. Patients' adaptive strategies sometimes worsened their symptoms, as in the case of muscular deconditioning. The healthcare system appeared deficient in managing these patients, characterized by a lack of health professional training, frequent inappropriate responses from healthcare providers, and stigmatization of psychological conditions. Conclusion: Despite its perceived benign nature, fibromyalgia should be regarded as a severe condition due to its substantial long-term consequences. Participants reported a challenging experience with the doctor-patient relationship, marked by a strong sense of dependence and a lack of recognition. The care pathway for these patients appeared unsuitable and disorderly, potentially resulting in iatrogenic consequences. The management of patients with fibromyalgia should be enhanced and directed toward a patient-centered approach. The study provides practical recommendations regarding communication methods and patient care.
RESUMO
OBJECTIVE: To determine whether persistent complete B cell (BC) depletion was associated with a better clinical response in rheumatoid arthritis (RA) patients long-term treated with rituximab (RTX). METHODS: We conducted a retrospective study including RA patients admitted for a new infusion between 2019 and 2021. The primary end point was the comparison of the mean DAS28-CRP at each of the 4 last infusion visits between patients with persistent complete BC depletion (mean CD19 counts <18/µL at each of the last 4 visits) or without persistent complete BC depletion (mean CD19 counts of the last 4 visits ≥18/µL). Secondary endpoints included DAS28, pain/fatigue VAS, CRP, gammaglobulins and the frequency of self-reported RA flares. RESULTS: Of the 126 patients in maintenance therapy with RTX (exposure period: 76 ± 5 months, n 14 ± 7 infusions received), 43 (34%) had persistent complete BC depletion at each of the 4 last infusions. The mean DAS28-CRP calculated at each of the 4 last infusion visits did not significantly differ according to persistence or not of complete BC depletion. This result remained unchanged after adjusting for antibody status, number of previous therapies, number of RTX infusion and cumulative RTX dose. All secondary outcomes were also not significantly different between both groups. CONCLUSION: Maintaining complete BC depletion does not appear to be a therapeutic target to achieve in RA patients in long-term maintenance therapy with RTX. There is a limited benefit of monitoring CD19 in RA patients long term treated with RTX and having achieved low disease activity/remission.
RESUMO
In this article, we review published literature on "telerheumatology", a term describing the use of telemedicine in rheumatology. This field has received considerable recent attention through the development of efficient digital technologies, resulting in a good level of satisfaction among patients and health care professionals. In 2020, the social distancing constraints during the COVID-19 pandemic accelerated more widespread adoption worldwide. Telerheumatology is particularly suited for patients with rheumatoid arthritis who have achieved a sustained therapeutic target of remission or low disease activity. To facilitate remote consultations and meet expectations of rheumatologists and patients, international and national guidelines have recently been proposed and existing tools, such as Patient-Reported Outcomes questionnaires, have had to be digitally adapted. In addition, telerheumatology toolkits are proposed by the Arab League of Associations for Rheumatology (ArLAR), the Association of American Medical College (AAMC), and the American College of Rheumatology (ACR) for all learners, from medical students to practicing clinicians, encouraging the acquisition of telehealth skills and facilitating their integration into their routine clinical practice. The main benefits reported for this mode of health care are greater access to specialty care, flexibility, reduced rates of missed appointments, as well as improved patient engagement and autonomy. Limitations include the absence of physical examination. However, to implement telerheumatology effectively and widely in daily clinical practice, some barriers still need to be addressed. These include training of health care professionals, technological restrictions and reimbursement mechanisms. Despite the advantages of telerheumatology, it is not intended to replace face-to-face visits, but rather as a way to enhance access to care, service delivery and health care support for patients.

The lack of validated tools to predict rheumatoid arthritis (RA) disease course warrants the development of new reliable biomarkers. Our aim was to evaluate the merit of circulating SEMA4A for the prediction of outcomes in patients with RA. In a first cohort of 101 consecutive RA patients followed up for 41 ± 15 months, increased baseline SEMA4A levels were identified as an independent predictor of treatment failure (hazard ratio, HR 2.71, 95% CI 1.14-6.43), defined by the occurrence of patient-reported flares and initiation or change of targeted therapy. The highest predictive value of treatment failure was obtained with the combination of increased circulating SEMA4A and/or Disease Activity Score (DAS) 28-CRP > 3.2 and/or active synovitis on doppler ultrasound (HR 10.42, 95% CI 1.41-76.94). In a second independent cohort of 40 consecutive RA patients who initiated new therapy because of insufficient disease control, baseline SEMA4A levels were significantly higher in patients who further experienced none or moderate response, and SEMA4A concentrations were markedly decreased in the group of patients with good clinical response as compared to non-responders. Circulating SEMA4A appears as an appealing biomarker in RA with ability to predict treatment failure, and with association with response to therapy.

BACKGROUND: Uncontrolled T-cell activation plays a key role in systemic sclerosis (SSc). Arsenic trioxide (ATO) has immunological effects and has demonstrated potential in preclinical SSc models. In this study, we assessed the efficacy of ATO in Fra2 transgenic (Fra2TG) mice, which develop severe vascular remodeling of pulmonary arterioles and nonspecific interstitial pneumonia-like lung disease, closely resembling human SSc-associated pulmonary hypertension, therefore partially resembling to the SSc human disease. METHODS: The efficacy of ATO in Fra2TG mice was evaluated through histological scoring and determination of cell infiltration. Fibrotic changes in the lungs were assessed by measuring collagen content biochemically, using second harmonic generation to measure fibrillar collagen, and imaging via computed tomography. Cardiovascular effects were determined by measuring right ventricular systolic pressure and vessel remodeling. The mechanism of action of ATO was then investigated by analyzing lung cell infiltrates using flow cytometry and bulk RNA with sequencing techniques. RESULTS: After ATO treatment, the Ashcroft histological score was substantially decreased by 33% in ATO-treated mice compared to control mice. Other investigations of fibrotic markers showed a trend of reduction in various measurements of fibrosis, but the differences did not reach significance. Further cardiovascular investigations revealed convergent findings supporting a beneficial effect of ATO, with reduced right ventricular systolic pressure and medial wall thickness, and a significant decrease in the number of muscularized distal pulmonary arteries in ATO-treated Fra2TG mice compared to untreated Fra2TG mice. Additionally, inflammatory cell infiltration was also markedly reduced in lesioned lungs. A reduction in the frequency of CD4 + and T effector memory cells, and an increase in the percentage of CD4 + T naive cells in the lungs of ATO-treated Fra-2TG mice, was observed when compared to PBS group Fra-2Tg mice. RNA-seq analysis of ATO-treated mouse lungs revealed a downregulation of biological pathways associated with immune activity and inflammation, such as T-cell activation, regulation of leucocyte activation, leucocyte cell-cell adhesion, and regulation of lymphocyte activation. CONCLUSIONS: Our results suggest the clinical relevance of ATO treatment in SSc. Using the Fra2TG mouse model, we observed significant lung histological changes, a trend towards a decrease in various fibrotic makers, and a strong reduction in vascular remodeling. The mechanism of action of ATO appears to involve a marked counteraction of the immune activation characteristic of SSc, particularly T-cell involvement. These findings pave the way for further studies in SSc.

OBJECTIVE: We aimed to compare two matched populations of patients with MTCD with and without associated ILD and to identify predictive factors for ILD progression and severity. METHODS: This international multicenter retrospective study (14 tertiary hospitals), included MCTD patients who fulfilled at least one historical MCTD classification criteria. ILD was defined by the presence of typical chest high-resolution computed tomography (HRCT) abnormalities. Factors associated with ILD were assessed at baseline. Long-term progressive ILD was assessed in MCTD-ILD patients with multiple forced vital capacity (FVC) measurements. RESULTS: 300 patients with MCTD were included. Mean age at diagnosis was 39.7 ± 15.4 years and 191 (63.7%) were women. Mean follow-up was 7.8 ± 5.5 years. At baseline, we identified several factors associated with ILD presence: older age (p = 0.01), skin thickening (p = 0.03), upper gastro-intestinal (GI) symptoms (p<0.001), FVC <80% (p<0.0001), diffusing capacity for carbon monoxide <80% (p<0.0001), anti-topoisomerase antibodies (p = 0.01), SSA/Ro antibodies (p = 0.02), cryoglobulinemia (p = 0.04) and elevated C-reactive protein (p<0.001). Patients with MTCD-ILD were more likely to be treated with synthetic immunosuppressant agents (p<0.001) in particular mycophenolate mofetil (p = 0.03). Digital ulcers (DU) were identified as a risk factor for FVC decline >10%. During follow-up mortality was higher in the MTCD-ILD group (p<0.001). CONCLUSION: In this large international cohort of patients with MTCD, we identified different factors associated with ILD. Our findings also provide evidence that MCTD-ILD patients have increased mortality and that DU are associated with progressive lung disease.

INTRODUCTION: Baricitinib, an orally available small-molecule inhibitor of Janus kinase (JAK)1 and JAK2, is indicated to treat active moderate-to-severe rheumatoid arthritis (RA). OBJECTIVE: This systematic review described the real-world clinical characteristics of baricitinib-treated patients with RA, prescription patterns, effectiveness, drug persistence, patient-reported outcomes (PROs; physical function, pain, health-related quality of life [HRQoL]), patient global assessment (PGA), and safety of baricitinib. METHODS: A PRISMA systematic review of real-world studies was conducted to identify relevant literature published between January 2016 and September 2022 using MEDLINE®, EMBASE®, and evidence-based medicine review databases. Websites or online repositories of the American College of Rheumatology and the European Alliance of Associations for Rheumatology were searched manually to include relevant abstracts from conferences held between January 2016 and November 2022. RESULTS: A total of 11,472 records were identified by searching online databases. Seventy studies were included in the study, of which 40 were abstracts. Most patients were older (51-71 years), female, and with mean RA duration of 4-19 years. Baricitinib was mostly used after the failure of one or more bDMARDs, and 4 mg dosing was prevalent in patients with RA (range 22-100%). Clinical effectiveness of baricitinib was reported in real-world settings regardless of prior biologic/targeted synthetic disease-modifying antirheumatic drug (DMARD) use and concomitant conventional synthetic DMARD use. Achievement of Clinical Disease Activity Index (CDAI) remission was reported in 8.7-60% of patients at week 12 and CDAI low disease activity (LDA) in 20.2-81.6% at week 24. The proportion of patients attaining Simple Disease Activity Index (SDAI) remission was reported in 12% at week 4 to 45.4% at 24 weeks. Drug persistence was high, similar, or equal to anti-tumor necrosis factor drugs. No new safety signals were identified. CONCLUSION: Baricitinib demonstrated effectiveness in the real-world setting with a consistent safety profile observed in clinical studies. Better persistence rates for baricitinib compared to bDMARDs with improvement in PROs were reported, although baricitinib-treated patients had RA with poor prognostic characteristics.
RESUMO
OBJECTIVES: Patients with connective tissue diseases can develop interstitial lung disease (ILD), leading to a progressive fibrosing ILD (PF-ILD) phenotype in some cases. We aimed to investigate the occurrence of PF-ILD in idiopathic inflammatory myopathies (IIMs), and factors potentially predicting this phenotype. Secondary aims were to assess the radiological pattern and factors associated with IIMs-ILD. METHODS: Patients with IIMs from our multicentric prospective cohort were retrospectively evaluated. Data were recorded at IIMs and ILD diagnosis, and during follow-up. Patients with ILD were classified according to the predominant high-resolution CT (HRCT) pattern: non-specific interstitial pneumonia (NSIP), usual interstitial pneumonia (UIP) and organising pneumonia (OP). PF-ILD was defined according to the 2022 American Thoracic Society (ATS), European Respiratory Society (ERS), Japanese Respiratory Society (JRS) and Latin American Thoracic Society (ALAT) guidelines. Univariate and multivariate analyses were performed to identify factors associated to ILD and to PF-ILD. RESULTS: Of 253 patients with IIMs, 125 (49%) had ILD: 99 (78%) at IIMs diagnosis and 26 (22%) during follow-up (21/26 within 5 years). Multivariate analysis identified anti-Jo-1, anti-MDA5, anti-Ro52, high score on manual muscle test, mechanic's hands and Raynaud's phenomenon as independently associated with ILD. The predominant HRCT pattern was NSIP (50% of patients), followed by UIP (28%) and OP (22%). At 1-year follow-up, PF-ILD occurred in 18% of IIMs-ILD. PF-ILD was predicted by anti-MDA5, heliotropic rash, xerostomia and xerophthalmia at univariate but not at multivariate analysis. CONCLUSION: Patients with IIM should be carefully screened for ILD at IIMs diagnosis and yearly during follow-up. All patients with IIMs-ILD should be carefully monitored to capture ILD progression since a consistent proportion of them are expected to develop PF-ILD.

OBJECTIVE: To describe the clinical efficacy of tixagevimab/cilgavimab in pre-exposure prophylaxis in patients at risk of severe COVID-19 and unresponsive to vaccination (anti-SARS-CoV-2 antibodies <260 BAU/mL) in rheumatology. METHODS: In this multicenter observational study we included patients with autoimmune or inflammatory diseases who received a pre-exposure prophylaxis by tixagevimab/cilgavimab between December 2021 and August 2022. The endpoint was incidence and severity of COVID-19. RESULTS: Tixagevimab/cilgavimab was administered to 115 patients, median age 62 years (52-71), with chronic arthritis (n = 53), connective tissue disease (n = 38) or vasculitis (n = 11). Main background immunosuppressants were rituximab (n = 98), corticosteroids (n = 62, median dose 5mg, CI95% 5-8 mg) and methotrexate (n = 48). During a median follow-up of 128 days (93-173), COVID-19 occurred in 23/115patients (20%), Omicron identified for the 8 genotyped patients. During study period, the average weekly incidence was 1071/100.000 inhabitants in Ile-de-France vs. 588/100.000 in our patients. Patients who received a 2-injections regimen had a lower risk of infection than with a single injection (16/49, 33% vs. 5/64, 8%, p = 0.0012). The COVID-19+ patients did not differ from uninfected patients concerning age, comorbidities, underlying rheumatic disease, immunosuppressant. All COVID-19 were non-severe. The tolerance of injections was excellent. CONCLUSION: In a population with autoimmune or inflammatory diseases at risk of severe COVID-19 unresponsive to vaccination, pre-exposure prophylaxis by tixagevimab/cilgavimab was associated with lower incidence of COVID-19 and no severe infection to report.
RESUMO
OBJECTIVES: The efficacy of anti-IL6 receptors such as Tocilizumab (TCZ) was demonstrated in patients with Polymyalgia Rheumatica (PMR) in two recent randomized controlled trials. The objective of this multicentre retrospective study was to assess the efficacy of TCZ in PMR patients requiring GC-sparing treatment, as well as different strategies for TCZ withdrawal. METHODS: We conducted a multicentre study in French tertiary health care departments for patients with PMR. PMR patients receiving off-label TCZ between 2015 and 2022 were included. The primary end point was the proportion of patients tapering to glucocorticoids (GCs) ≤5mg/day 6 months after the first TCZ infusion. The secondary endpoints were the proportion in whom GC was discontinued during follow-up, and the proportion of patients in whom TCZ was discontinued. RESULTS: Fifty-three PMR patients were included. Thirty-one (31) patients suffered from active PMR despite csDMARDs. GCs were ≤5mg/day in 77% of the patients (95% confidence interval [CI95%]: 36-89) at 6 months, and in 97% of the patients at 12 months. Six and 12 months after the first TCZ infusion, the proportions of GC-free patients were 22.5% (CI95%: 12.7-37.8) and 58.3% (CI95%: 43.2-74.1), respectively. Among TCZ withdrawal strategies, TCZ infusion spacing and TCZ dose reduction were more successful (success in 87% and 79% of attempts, respectively) than TCZ discontinuation (success in 52% of attempts; p= 0.012 and p= 0.039, respectively). CONCLUSION: In GC-dependent PMR patients, treatment with TCZ led to a drastic decrease in GC dose and remission of PMR. TCZ dose reduction or TCZ infusion spacing are good options to consider in TCZ withdrawal.
