Objectives: To develop and validate a web-based ecological momentary assessment (EMA) tool to enhance symptoms monitoring among patients with Sjögren's disease (SjD)., Methods: Consecutive adults with SjD were enrolled in this pilot observational study. Participants used the WebApp over a 3-month period, for the daily collection of individual EULAR Sjögren's Syndrome Patient Reported Index (ESSPRI) scales and separate assessment of eyes and mouth dryness, using 0-10 numerical scales. Primary outcome was the measure of the interdaily variability of symptoms. Data collected through the WebApp were compared with those obtained with paper-based questionnaires administered during a final visit, using distinct approaches (predicted error, maximum negative error and maximum positive error). User experience was assessed using the System Usability Scale (SUS) score., Results: Among the 45 participants, 41 (91.1%) were women. Median age was 57 years (IQR: 49-66). Daily variability of symptoms ranged between 0.5 and 0.8 points across the scales. Over the 3-month period, the predicted error ranged between -1.2 and -0.3 points of the numerical scales. The greatest differences were found for fatigue (-1.2 points (IQR: -2.3 to -0.2)) and ESSPRI score (-1.2 points (IQR: -1.7 to -0.3)). Over the last 2 weeks, the predicted error ranged between - 1.2 and 0.0 points. Maximum negative error ranged between -2.0 and -1.0 points, and maximum positive error between -0.3 and 0.0 points. Median SUS score was 90 (IQR: 85-95)., Conclusion: Our results demonstrate the usability and the relevance of our web-based EMA tool for capturing data that closely reflects daily experiences of patients with SjD., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Purpose: Evaluate the benefit of 2-deoxy-2-[18F]-fluoro-D-glucose ([ 18 F] FDG) positron emission tomography/computed tomography (PET/CT) for the therapeutic assessment of Abatacept (ABA) as first-line therapy in early-onset polymyalgia rheumatica (PMR) patients., Methods: This was an ancillary study of ALORS trial (Abatacept in earLy Onset polymyalgia Rheumatica Study) assessing the ability of ABA versus placebo to achieve low disease activity (C-Reactive Protein PMR activity score (CRP PMR-AS) ≤ to 10) without glucocorticoid (GC) at week 12 in patients with early-onset PMR. The patients underwent [ 18 F] FDG PET/CT at baseline and after 12 weeks of treatment. Responses to treatments were evaluated according to CRP PMR-AS, Erythrocyte Sedimentation Rate (ESR) PMR-AS, Clin PMR-AS, and CRP-Imputed (Imput-CRP) PMR-AS. Quantitative score by maximal standardized uptake value (SUVmax) and combined qualitative scores according to liver uptake (Leuven, Leuven/Groningen, and Besançon Scores) were used for assessment of [ 18 F] FDG uptake in regions of interest (ROI) usually affected in PMR. Student's t-test was applied to evaluate the clinical, biological, and [ 18 F] FDG uptake variation difference in ABA and placebo groups between W0 and W12. Subgroup analysis by GC rescue was performed., Results: At W12, there was no significant difference according to SUVmax between the ABA and the placebo groups in all ROI. Subgroup analysis according to GC administration demonstrated a significant (p 0.047) decrease in SUVmax within the left sternoclavicular joint ROI in the ABA group (- 0.8) compared to the placebo group (+ 0.6) without GC rescue. Other results did not reveal any significant difference between the ABA and placebo groups. According to combined qualitative scores, there was no significant difference between ABA and placebo groups for the direct comparison analysis and subgroup analysis according to GC rescue., Conclusion: [ 18 F] FDG PET/CT uptake did not decrease significantly after ABA compared to placebo in anatomical areas usually affected in PMR patients. These results are correlated with the clinical-biological therapeutic assessment., Clinical Trial Registration: The study was approved by the appropriate ethics committee (CPP Sud-Est II Ref CPP: 2018-33), and all patients gave their written informed consent before study enrollment. The protocol was registered on Clinicaltrials.gov (NCT03632187)., (© 2023. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)

Objective: The C reactive protein polymyalgia rheumatica activity score (CRP-PMR-AS) is a composite index that includes CRP levels and was developed specifically for PMR. As treatments such as interleukin-6 antagonists can normalise CRP levels, the erythrocyte sedimentation rate (ESR) of PMR-AS, the clinical (clin)-PMR-AS and the imputed-CRP (imp-CRP)-PMR-AS have been developed to avoid such bias. Our primary objective was to measure the correlation of these activity scores. Our secondary objective was to evaluate the concordance between different cutoffs of the PMR-ASs., Method: Data from the Safety and Efficacy of tocilizumab versus Placebo in Polymyalgia rHeumatica With glucocORticoid dEpendence (SEMAPHORE) trial, a superiority randomised double-blind placebo-controlled trial, were subjected to post hoc analysis to compare the efficacy of tocilizumab versus placebo in patients with active PMR. The CRP-PMR-AS, ESR-PMR-AS, clin-PMR-AS and imp-CRP-PMR-AS were measured at every visit. The concordance and correlation between these scores were evaluated using kappa correlation coefficients, Bland-Altman correlations, intraclass correlation coefficients (ICCs) and scatter plots., Results: A total of 101 patients were included in the SEMAPHORE trial, and 100 were analysed in this study. The correlation between the PMR-ASs was excellent, as the ICC and kappa were >0.85 from week 4 until week 24 (CRP-PMR-AS ≤10 or >10). Bland-Altman plots revealed that the differences between the CRP-PMR-AS and the other threescores were low. The cut-off values for the clin-PMR-AS were similar to those for the CRP-PMR-AS 86% of the time., Conclusion: The correlation between all the PMR-ASs was excellent, reflecting the low weight of CRP. In clinical trials using drugs that have an impact on CRP, the derived activity scores can be used., Trial Registration Number: NTC02908217., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: Medium-dose glucocorticoids can improve symptoms in nearly all patients with polymyalgia rheumatica. According to its good safety profile, abatacept could be used instead of glucocorticoids in early polymyalgia rheumatica. We aimed to determine whether the efficacy of abatacept is sufficient to justify larger studies in early polymyalgia rheumatica., Methods: To evaluate whether abatacept allows low disease activity without glucocorticoids in early polymyalgia rheumatica, we conducted a proof-of-concept, randomised, double-blind, placebo-controlled, parallel-group trial. Participants were recruited from five centres in France (in Brest, Le Mans, Morlaix, Dinan and Saint Malo, and Strasbourg) and were included if they had recent-onset (<6 months) polymyalgia rheumatica with a C-reactive protein (CRP) polymyalgia rheumatica activity score (PMR-AS) of more than 17 without any signs or symptoms of giant cell arteritis (clinical and [ 18 F]fluorodeoxyglucose PET-CT evaluation). Participants were randomly assigned (1:1) to receive weekly subcutaneous abatacept (125 mg) or matching placebo, with glucocorticoid rescue therapy allowed in cases of high disease activity, for 12 weeks, and then glucocorticoid treatment based on disease activity, until week 36. Investigators, patients, outcome assessors, and sponsor personnel were masked to group assignments. The primary endpoint was low disease activity (CRP PMR-AS ≤10) at week 12 without glucocorticoids and without rescue treatment. The study was powered to demonstrate a 60% difference in response rates between groups. Open-ended adverse events were collected at each visit by clinicians and were categorised following system organ class classification after study completion. The ALORS trial is registered with ClinicalTrials.gov, NCT03632187., Findings: 34 patients (22 women and 12 men) were randomly assigned between Dec 13, 2018, and Oct 21, 2021. All patients who had been randomly assigned were included in the analysis. The primary endpoint was reached by eight (50%) of 16 patients in the abatacept group and four (22%) of 18 patients in the placebo group (relative risk 2·2 [0·9-5·5]); crude p=0·15; adjusted p=0·070). Eight (50%) patients in the abatacept and 15 (83%) in the placebo group had adverse events. Four patients (one [6%] in the abatacept group and three [17%] in the placebo group) had serious adverse events. There were no deaths or new safety concerns., Interpretation: This study suggests that the effect of abatacept alone is not strong enough to justify larger studies in early polymyalgia rheumatica. This is only a first step in deciding whether a larger study should be conducted in early polymyalgia rheumatica and does not exclude a potential effect of abatacept in glucocorticoid-dependent polymyalgia rheumatica., Funding: BMS Pharma France., Competing Interests: Declaration of interests ASa reports work from speakers bureaus for speakers bureau for AbbVie, Bristol Myers Squibb (BMS), Galapagos, Lilly, Novartis, Nordic, Pfizer, Roche-Chugai, Sanofi, and Union Chimique Belge (UCB); and grants or research support from AbbVie, BMS, Lilly, and Novartis.

Objective: To determine whether repeated minor salivary gland biopsy (MSGB) has a clinical diagnostic utility in patients with suspicion of Sjögren's syndrome (SS)., Methods: Clinical, biological, pathological data and physician's diagnosis after each MSGB from patients with suspected primary or secondary SS who had benefited from 2 MSGB at Brest University Hospital between January 1st, 1990 and January 14th, 2015, were retrospectively collected. We compared the characteristics of patients with and without first positive MSGB, concordance between the MSGB, and analyzed the modifications of diagnosis after the second MSGB., Results: Ninety-three patients were included, first MSGB was positive for 23 and negative for 70. Patients with first positive MSGB had more often renal involvement (P<0.05) and hypergammaglobulinemia (P=0.01), anti-SSA antibodies (P<0.05) and positive second biopsy with focus score ≥ 1 or Chisholm>2 (P<0.01). The mean time between the 2 MSGB was 5.7±4.3 years. The concordance between the results of the 2 biopsies was low (κ = 0.34). MSGB influenced diagnostic's change in 10 cases where the second MSGB was always guided by new specific clinical manifestations., Conclusion: We observed a low concordance between 2 MSGB in patients with suspected pSS in our study. Despite this variability, performing a second MSGB changed the initial diagnosis in only a minority of the patients and was particularly useful when clinical manifestations had deeply evolved., (Copyright © 2022 Société française de rhumatologie.

Importance: Few treatments are available for patients with glucocorticoid-dependent polymyalgia rheumatica. IL-6 antagonists may reduce disease activity in patients with active glucocorticoid-dependent polymyalgia rheumatica., Objective: To compare the efficacy of tocilizumab vs placebo in patients with glucocorticoid-dependent polymyalgia rheumatica., Design, Setting, and Participants: This double-blind, parallel-group, placebo-controlled randomized clinical trial enrolled 101 patients with polymyalgia rheumatica at 17 hospitals in France from February 2017 to October 2019. Final follow-up occurred in November 2020. Inclusion criteria were persistent disease activity (polymyalgia rheumatica activity score computed using the C-reactive protein level [CRP PMR-AS] >10) and prednisone dose greater than or equal to 10 mg per day., Interventions: Patients were randomly assigned to receive intravenous tocilizumab (8 mg/kg; n = 51) or placebo (n = 50) every 4 weeks for 24 weeks, combined with predefined standardized tapering of oral prednisone., Main Outcomes and Measures: The primary efficacy end point was CRP PMR-AS less than 10 (range, 0-100; higher values indicate greater activity; no minimal clinically important difference defined) combined with either prednisone dose less than or equal to 5 mg per day or a decrease in prednisone dose greater than or equal to 10 mg from baseline at week 24. There were 11 secondary outcomes assessed at week 24 included in this report, including disease activity (measured by CRP PMR-AS) and the proportion of patients no longer taking prednisone., Results: Of the 101 randomized patients (mean age, 67.2 years; 68 [67.3%] women), 100 (99%) received at least 1 infusion and 100 completed the trial. The primary end point was achieved in 67.3% of patients in the tocilizumab group and 31.4% of patients in the placebo group (adjusted difference, 36.0% [95% CI, 19.4%-52.6%]; adjusted relative risk, 2.3 [95% CI, 1.5-3.6]; P < .001). Of 11 reported secondary end points at 24 weeks, 7 showed significant differences favoring tocilizumab, including mean CRP PMR-AS score (7.5 [95% CI, 5.4-9.6] vs 14.9 [95% CI, 11.4-18.4]; adjusted difference, -7.5 [95% CI, -11.2 to -3.8]; P < .001) and the percentage of patients no longer receiving prednisone (49.0% vs 19.6%; adjusted difference, 29.3% [95% CI, 18.9%-39.7%]; adjusted relative risk, 2.5 [95% CI, 1.8-3.5]; P < .001). The most frequent adverse events were infections, experienced by 23 patients (46.9%) in the tocilizumab group and 20 (39.2%) in the placebo group., Conclusions and Relevance: Among patients with active polymyalgia rheumatica despite prednisone therapy, tocilizumab, compared with placebo, resulted in a significantly greater percentage of patients with a CRP PMR-AS less than 10 with reduced prednisone requirements at week 24. Further research is needed to confirm efficacy and to determine the balance of potential benefits and harms., Trial Registration: ClinicalTrials.gov Identifier: NCT02908217.
