Synovial tissue research has become widely developed in several rheumatology centres, however, large discrepancies exist in the way synovial tissue is handled and, more specifically, how data ...pertaining to biopsy procedure, quality check and experimental results are reported in the literature. This heterogeneity hampers the progress of research in this rapidly expanding field. In that context, under the umbrella of European Alliance of Associations for Rheumatology, we aimed at proposing points to consider (PtC) for minimal reporting requirements in synovial tissue research.
Twenty-five members from 10 countries across Europe and USA met virtually to define the key areas needing evaluation and formulating the research questions to inform a systematic literature review (SLR). The results were presented during a second virtual meeting where PtC were formulated and agreed.
Study design, biopsy procedures, tissue handling, tissue quality control and tissue outcomes (imaging, DNA/RNA analysis and disaggregation) were identified as important aspects for the quality of synovial tissue research. The SLR interrogated four databases, retrieved 7654 abstracts and included 26 manuscripts. Three OPs and nine PtC were formulated covering the following areas: description of biopsy procedure, overarching clinical design, patient characteristics, tissue handling and processing, quality control, histopathology, transcriptomic analyses and single-cell technologies.
These PtC provide guidance on how research involving synovial tissue should be reported to ensure a better evaluation of results by readers, reviewers and the broader scientific community. We anticipate that these PtC will enable the field to progress in a robust and transparent manner over the coming years.
ObjectiveTo update the EULAR 2020 systematic literature review (SLR) on efficacy and safety of immunomodulatory agents in SARS-CoV-2 infection.MethodsAs part of a EULAR taskforce, a systematic ...literature search update was conducted from 11 December 2020 to 14 July 2021. Two reviewers independently identified eligible studies and extracted data on efficacy and safety of immunomodulatory agents used therapeutically in SARS-CoV-2 infection at any stage of disease. The risk of bias (RoB) was assessed with validated tools.ResultsOf the 26 959 records, 520 articles were eligible for inclusion. Studies were mainly at high or unclear RoB. New randomised controlled trials (RCTs) on tocilizumab clarified its benefit in patients with severe and critical COVID-19, mainly if associated with glucocorticoids. There are emergent data on the usefulness of baricitinib and tofacitinib in severe COVID-19. Other therapeutic strategies such as the use of convalescent plasma and anti-SARS-CoV-2 monoclonal antibodies showed efficacy in subjects not mounting normal anti-SARS-CoV-2 antibody responses.ConclusionThis new SLR confirms that some immunomodulators (tocilizumab and JAK inhibitors) have a role for treating severe and critical COVID-19. Although better evidence is available compared with the previous SLR, the need of RCT with combination therapy (glucocorticoids+anti-cytokines) versus monotherapy with glucocorticoids still remains alongside the need for standardisation of inclusion criteria and outcomes to ultimately improve the care and prognosis of affected people. This SLR informed the 2021 update of the EULAR points to consider on the use of immunomodulatory therapies in COVID-19.
•An annual review of patients with axial spondyloarthritis encompassing disease activity, severity, comorbidities, employment, psychological factors, and lifestyle is recommended.•The specific ...content of this annual review has never been proposed.•This initiative provided a reporting framework including all components needing to be assessed during this review.•This document was obtained after a literature search and an expert consensus-driven approach.
National and international scientific societies advocate for a regular, systematic, and standardized global evaluation of axial spondyloarthritis (axSpA) patients. However, there are no recommendations specifying the content of this global evaluation. This initiative aimed to propose a standardized reporting framework, using evidence-based and consensus approaches, to collect data on all domains of axSpA.
A literature review and consensus process involved a steering committee and an expert panel of 37 rheumatologists and health professionals. The first steering committee took place in March 2022 and identified the main domains for inclusion in the standardized report. A hierarchical literature review was conducted to identify items within these domains and tools for assessment. The items and tools for assessment were discussed and consensus was reached through a vote session during an expert meeting that took place in March 2023.
The steering committee identified four main domains to include in the standardized reporting framework: disease assessment, comorbidities, lifestyle, and quality of life. Items and tools for assessment were adopted after the expert meeting. Additionally, recommendations regarding digital tools (websites, apps, social media) were provided.
This initiative led to a consensus, based on evidence and expertise, on a reporting framework for use during periodic systematic global evaluations of axSpa in daily practice.
•IMSYC is a new synovitis score adding 5 immunostainings to Krenn's original synovitis score.•IMSYC has a better sensitivity and specificity than original synovitis score to discriminate inflammatory ...and non-inflammatory arthritis.•IMSYC allows a more accurate synovitis characterization.
Krenn synovitis Score has been developed by Krenn et al. in order to assess synovitis severity and is used in synovial research. Cell signature of synovial tissue can be studied using immunohistochemistry and is of interest as a biomarker for both prognosis and prediction of response to treatment. However, no synovitis score including immunohistochemistry exists yet. In order to answer this unmet need, we propose a new Immunologic Synovitis score (IMSYC) adding 5 components to the Krenn score: CD68, CD3, CD20, CD31 and Ki67 immunostaining. In this study, we aimed to validate this new IMSYC by studying its diagnostic performances in a well-defined collection of synovial samples.
Synovial samples from patients were obtained during surgical procedures. CD68, CD3, CD20, CD31 and KI67 immunohistochemistry were performed.
In total, 77 patients were included. In total, 45 were females, mean age was 63.1 years. Forty had inflammatory arthritis, mainly rheumatoid arthritis (31/40). Non inflammatory arthritis group included 35 patients with mainly osteoarthritis. Mean Krenn score and IMSYC were significantly higher in the inflammatory group (P<0.001). ROC analysis of diagnostic performances determined the score of 13.5 out of 24 as the cut-off that gave the best ratio for discrimination between inflammatory and non-inflammatory arthritis with a sensitivity of 71.8% and specificity of 98%.
We propose a new synovitis score including immunohistochemistry. This score has a better sensitivity and specificity than the Krenn score and represents a more functional synovitis evaluation. IMSYC could be further used in better categorizing synovial tissue phenotype and give a basis for tissue driven therapy.
Cystic angiomatosis (CA) is a rare disorder causing bony cysts. It displays some similarity to Gorham-Stout disease (GSD), but has a much better local prognosis, despite the larger number of cysts. ...These 2 conditions also differ in terms of their location, visceral involvement, and response to treatment.
We report 4 cases of CA, including 1 sclerosing form, which we compare with cases from a literature review performed with PRISMA methodology.
We reviewed 38 articles describing 44 other patients. Mean age at diagnosis for the 48 patients (our 4 patients + the 44 from the review) was 22.5 years, and 28 of the patients were men. The femur was involved in 81% (n = 39), the pelvis in 73% (n = 35), the humerus in 52% (n = 25), the skull in 48% (n = 23), and the vertebrae in 44% (n = 21). Visceral lymphangiomatosis (either clinical, or detected on autopsy) was also reported in 35% (n = 18) of the patients. The spleen was the most frequently involved organ (n = 12), followed by the lungs and pleura (n = 8). Liver cysts and/or chylothorax were rarely reported (5 cases), but were invariably fatal. Radiation therapy on bone or soft tissue masses was ineffective, as was interferon alpha, in the 2 patients in which this drug was tested. The efficacy of bisphosphonate was at best equivocal.
The progression of CA is unpredictable and treatments effective against GSD, such as bisphosphonates and radiotherapy, have proved ineffective for this condition. New treatments are thus urgently required.
BackgroundThe aim of this work was to summarise the literature evaluating the impact of biopsy procedures, tissue handling, tissue quality and disease-specific aspects including joint biopsied and ...disease stage, on synovial tissue outcome.MethodsTwo reviewers independently identified eligible studies according to the Patients, Intervention, Comparator and Outcome framework obtained for five research questions formulated during the first EULAR task force meeting to produce points to consider (PtC) for minimal reporting requirements in synovial tissue studies. The databases explored were Medline, Embase, CENTRAL and Cinhal. The risk of bias of each study was evaluated using an adapted version of the Joanna Briggs Institute checklist for analytical cross-sectional studies.ResultsOf the 7654 records yielded, 75 full texts were assessed, leading to the inclusion of 26 manuscripts in the systematic literature review (SLR). Two papers assessed the impact of biopsy procedures on the quality and quantity of tissue retrieved alongside patient tolerability; six papers focused on synovial tissue variability. Four papers studied the impact of sample handling or randomisation and 14 assessed the impact of disease stage and state, namely early or established active rheumatoid arthritis and remission on histopathological and transcriptomic results.ConclusionsThis SLR informs the EULAR PtC for minimal reporting requirements in synovial tissue research in rheumatology. Characteristics related to the study design, population, sample handling, randomisation and analysis can affect the final synovial tissue outcome in the studies reviewed. Thus, accurate reporting of these factors is required in order to ensure the scientific validity of manuscripts describing synovial tissue outcomes.
BackgroundMobile health applications (apps) are available to enable people with rheumatic and musculoskeletal diseases (RMDs) to better self-manage their health. However, guidance on the development ...and evaluation of such apps is lacking.ObjectivesThe objective of this EULAR task force was to establish points to consider (PtC) for the development, evaluation and implementation of apps for self-management of RMDs.MethodsA systematic literature review of app content and development strategies was conducted, followed by patient focus group and an online survey. Based on this information and along with task force expert opinion, PtC were formulated in a face-to-face meeting by a multidisciplinary task force panel of experts, including two patient research partners. The level of agreement among the panel in regard to each PtC was established by anonymous online voting.ResultsThree overarching principles and 10 PtC were formulated. Three PtC are related to patient safety, considered as a critical issue by the panel. Three are related to relevance of the content and functionalities. The requirement for transparency around app development and funding sources, along with involvement of relevant health professionals, were also raised. Ease of app access across ages and abilities was highlighted, in addition to considering the cost benefit of apps from the outset. The level of agreement was from 8.8 to 9.9 out of 10.ConclusionThese EULAR PtC provide guidance on important aspects that should be considered for the development, evaluation and implementation of existing and new apps.
Striving for harmonisation of specialty training and excellence of care in rheumatology, the European League Against Rheumatism (EULAR) established a task force to develop points to consider (PtCs) ...for the assessment of competences during rheumatology specialty training.
A systematic literature review on the performance of methods for the assessment of competences in rheumatology specialty training was conducted. This was followed by focus groups in five selected countries to gather information on assessment practices and priorities. Combining the collected evidence with expert opinion, the PtCs were formulated by the multidisciplinary task force, including rheumatologists, medical educationalists, and people with rheumatic and musculoskeletal diseases. The level of agreement (LoA) for each PtC was anonymously voted online.
Four overarching principles and 10 PtCs were formulated. The overarching principles highlighted the importance of assessments being closely linked to the rheumatology training programme and protecting sufficient time and resources to ensure effective implementation. In the PtCs, two were related to overall assessment strategy (PtCs 1 and 5); three focused on formative assessment and portfolio (PtCs 2-4); three focused on the assessment of knowledge, skills or professionalism (PtCs 6-8); one focused on trainees at risk of failure (PtC 9); and one focused on training the trainers (PtC 10). The LoA (0-10) ranged from 8.75 to 9.9.
These EULAR PtCs provide European guidance on assessment methods throughout rheumatology training programmes. These can be used to benchmark current practices and to develop future strategies, thereby fostering continuous improvement in rheumatology learning and, ultimately, in patient care.
