Abatacept inhibits inflammation and onset of rheumatoid arthritis in individuals at high risk (ARIAA): a randomised, international, multicentre, double-blind, placebo-controlled trial.

BACKGROUND: Individuals with anti-citrullinated protein antibodies (ACPAs) and subclinical inflammatory changes in joints are at high risk of developing rheumatoid arthritis. Treatment strategies to intercept this pre-stage clinical disease remain to be developed. We aimed to assess whether 6-month treatment with abatacept improves inflammation in preclinical rheumatoid arthritis. METHODS: The abatacept reversing subclinical inflammation as measured by MRI in ACPA positive arthralgia (ARIAA) study is a randomised, international, multicentre, double-blind, placebo-controlled trial done in 14 hospitals and community centres across Europe (11 in Germany, two in Spain, and one in the Czech Republic). Adults (aged ≥18 years) with ACPA positivity, joint pain (but no swelling), and signs of osteitis, synovitis, or tenosynovitis in hand MRI were randomly assigned (1:1) to weekly subcutaneous abatacept 125 mg or placebo for 6 months followed by a double-blind, drug-free, observation phase for 12 months. The primary outcome was the proportion of participants with any reduction in inflammatory MRI lesions at 6 months. The primary efficacy analysis was done in the modified intention-to-treat population, which included participants who were randomly assigned and received study medication. Safety analyses were conducted in participants who received the study medication and had at least one post-baseline observation. The study was registered with the EUDRA-CT (2014-000555-93). FINDINGS: Between Nov 6, 2014, and June 15, 2021, 139 participants were screened. Of 100 participants, 50 were randomly assigned to abatacept 125 mg and 50 to placebo. Two participants (one from each group) were excluded due to administration failure or refusing treatment; thus, 98 were included in the modified intention-to-treat population. 70 (71%) of 98 participants were female and 28 (29%) of 98 were male. At 6 months, 28 (57%) of 49 participants in the abatacept group and 15 (31%) of 49 participants in the placebo group showed improvement in MRI subclinical inflammation (absolute difference 26·5%, 95% CI 5·9-45·6; p=0·014). Four (8%) of 49 participants in the abatacept group and 17 (35%) of 49 participants in the placebo group developed rheumatoid arthritis (hazard ratio [HR] 0·14 [0·04-0·47]; p=0·0016). Improvement of MRI inflammation (25 [51%] of 49 participants in the abatacept group, 12 [24%] of 49 in the placebo group; p=0·012) and progression to rheumatoid arthritis (17 [35%] of 49, 28 [57%] of 49; HR 0·14 [0·04-0·47]; p=0·018) remained significantly different between the two groups after 18 months, 12 months after the end of the intervention. There were 12 serious adverse events in 11 participants (four [8%] of 48 in the abatacept group and 7 [14%] of 49 in the placebo group). No deaths occurred during the study. INTERPRETATION: 6-month treatment with abatacept decreases MRI inflammation, clinical symptoms, and risk of rheumatoid arthritis development in participants at high risk. The effects of the intervention persist through a 1-year drug-free observation phase. FUNDING: Innovative Medicine Initiative.

Reporting Sacroiliac Joint Imaging Performed for Known or Suspected Axial Spondyloarthritis: Assessment of SpondyloArthritis International Society Recommendations.

Whereas previous projects attempted to standardize imaging in patients with axial spondyloarthritis (axSpA), few studies have been published about the need for specific details regarding the image acquisition and lesions that may be less familiar to general radiologists. This work reports consensus recommendations developed by the Assessment of SpondyloArthritis International Society (ASAS) that aim to standardize the imaging reports in patients suspected of having or with known axSpA. A task force consisting of radiologists and rheumatologists from ASAS and one patient representative formulated two surveys that were completed by ASAS members. The results of these surveys led to the development of 10 recommendations that were endorsed by 73% (43 of 59) of ASAS members. The recommendations are targeted to the radiologist and include best practices for the inclusion of clinical information, technical details, image quality, and imaging findings in radiology reports. These recommendations also emphasize that imaging findings that indicate differential diagnoses and referral suggestions should be included in the concluding section of the radiology report. With these recommendations, ASAS aims to improve the diagnostic process and care for patients suspected of having or with known axSpA.

Bimekizumab treatment in patients with active axial spondyloarthritis: 52-week efficacy and safety from the randomised parallel phase 3 BE MOBILE 1 and BE MOBILE 2 studies.

OBJECTIVES: Bimekizumab (BKZ), a monoclonal IgG1 antibody that selectively inhibits interleukin (IL)-17F in addition to IL-17A, has demonstrated superior efficacy versus placebo in patients with non-radiographic (nr-) and radiographic (r-) axial spondyloarthritis (axSpA) at Week 16. Here, the objective is to report the efficacy and safety of BKZ at Week 52. METHODS: BE MOBILE 1 (nr-axSpA; NCT03928704) and BE MOBILE 2 (r-axSpA; NCT03928743) comprised a 16-week, double-blind, placebo-controlled period, then a 36-week maintenance period. From Week 16, all patients received subcutaneous BKZ 160 mg every 4 weeks. RESULTS: Improvements versus placebo in Assessment of SpondyloArthritis International Society ≥40% response (primary endpoint), Ankylosing Spondylitis Disease Activity Score, high-sensitivity C-reactive protein levels and MRI inflammation of the sacroiliac joints/spine at Week 16 were sustained to Week 52 in BKZ-randomised patients. At Week 52, responses of patients switching from placebo to BKZ at Week 16 were comparable to BKZ-randomised patients. At Week 52, ≥1 treatment-emergent adverse events (TEAEs) were reported in 183 (75.0%) and 249 (75.5%) patients with nr-axSpA and r-axSpA, respectively. Serious TEAEs occurred in 9 (3.7%) patients with nr-axSpA and 20 (6.1%) patients with r-axSpA. Oral candidiasis was the most frequent fungal infection (nr-axSpA: 18 (7.4%); r-axSpA: 20 (6.1%)). Uveitis occurred in three (1.2%) and seven (2.1%) patients with nr-axSpA and r-axSpA, and inflammatory bowel disease in two (0.8%) and three (0.9%). CONCLUSIONS: At Week 52, dual inhibition of IL-17A and IL-17F with BKZ resulted in sustained efficacy across the axSpA spectrum; the safety profile was consistent with the known safety of BKZ. TRIAL REGISTRATION NUMBER: NCT03928704; NCT03928743.

Efficacy and safety of pharmacological treatment of psoriatic arthritis: a systematic literature research informing the 2023 update of the EULAR recommendations for the management of psoriatic arthritis.

OBJECTIVES: To obtain an overview of recent evidence on efficacy and safety of pharmacological treatments in psoriatic arthritis (PsA). METHODS: This systematic literature research (SLR) investigated the efficacy and safety of conventional synthetic (cs), biological (b) and targeted synthetic (ts) disease-modifying antirheumatic drugs (DMARDs) in patients with PsA. A systematic database search using Medline, EMBASE, Cochrane CENTRAL was conducted to identify relevant articles published since the previous update in 2019 until 28 December 2022. Efficacy was assessed in trials while for safety observational data were also considered. Adverse events of special interest were infections (including herpes zoster, influenza and tuberculosis), malignancies, major adverse cardiovascular events, venous thromboembolisms, liver disease, laboratory changes and psychiatric adverse events. No meta-analyses were performed. RESULTS: For efficacy, of 3946 articles screened, 38 articles (30 trials) were analysed. The compounds investigated included csDMARDs (leflunomide, methotrexate), bDMARDs inhibiting IL17 (bimekizumab, brodalumab, ixekizumab, izokibep, secukinumab,), IL-23 (guselkumab, risankizumab, tildrakizumab), IL-12/23 (ustekinumab) as well as TNF (adalimumab, certolizumab-pegol, etanercept, infliximab, golimumab) and Janus Kinase inhibitors (JAKi) (brepocitinib, deucravacitinib, tofacitinib, upadacitinib). The compounds investigated were efficacious in improving signs and symptoms of PsA, improving physical functioning and quality of life. For safety, 2055 abstracts were screened, and 24 articles analysed: 15 observational studies and 9 long-term follow-ups of trials, assessing glucocorticoids, TNFi, IL-17i, JAKi, IL-12/23i and PDE4i (apremilast). Safety indicators were generally coherent with the previous SLR in 2019. CONCLUSION: The results of this SLR informed the task force responsible for the 2023 update of the European Alliance of Associations for Rheumatology recommendations for pharmacological management of PsA.

Goodbye to the term 'ankylosing spondylitis', hello 'axial spondyloarthritis': time to embrace the ASAS-defined nomenclature.

Ankylosing spondylitis (AS) is the historic term used for decades for the HLA-B27-associated inflammatory disease affecting mainly the sacroiliac joints (SIJ) and spine. Classification criteria for AS have radiographic sacroiliitis as a dominant characteristic. However, with the availability of MRI of SIJ, it could be demonstrated that the disease starts long before definite SIJ changes become visible on radiographs. The Assessment of SpondyloArthritis international Society, representing a worldwide group of experts reached consensus on changes in the nomenclature pertaining to axial spondyloarthritis (axSpA), such as the terminology of diagnosis and of assessment of disease activity tools. These are important changes in the field, as experts in axSpA are now in agreement that the term axSpA is the overall term for the disease. A further differentiation, of which radiographic versus non-radiographic is only one aspect, may be relevant for research purposes. Another important decision was that the terms AS and radiographic axSpA (r-axSpA) can be used interchangeably, but that the preferred term is r-axSpA. Based on the decision that axSpA is the correct terminology, a proposal was made to officially change the meaning of the ASDAS acronym to 'Axial Spondyloarthritis Disease Activity Score'. In addition, for simplification it was proposed that the term ASDAS (instead of ASDAS-CRP) should be preferred and applied to the ASDAS calculated with C reactive protein (CRP). It is hoped that these changes will be used consequently for education, in textbooks, manuscripts and presentations.

Unmet need in rheumatology: reports from the Advances in Targeted Therapies meeting, 2023.

The Advances in Targeted Therapies meets annually, convening experts in the field of rheumatology to both provide scientific updates and identify existing scientific gaps within the field. To review the major unmet scientific needs in rheumatology. The 23rd annual Advances in Targeted Therapies meeting convened with more than 100 international basic scientists and clinical researchers in rheumatology, immunology, infectious diseases, epidemiology, molecular biology and other specialties relating to all aspects of immune-mediated inflammatory diseases. We held breakout sessions in five rheumatological disease-specific groups including: rheumatoid arthritis (RA), psoriatic arthritis (PsA), axial spondyloarthritis (axSpa), systemic lupus erythematosus (SLE), systemic sclerosis (SSc) and vasculitis, and osteoarthritis (OA). In each group, experts were asked to identify and prioritise current unmet needs in clinical and translational research. An overarching theme across all disease states is the continued need for clinical trial design innovation with regard to therapeutics, endpoint and disease endotypes. Within RA, unmet needs comprise molecular classification of disease pathogenesis and activity, pre-/early RA strategies, more refined pain profiling and innovative trials designs to deliver on precision medicine. Continued scientific questions within PsA include evaluating the genetic, immunophenotypic, clinical signatures that predict development of PsA in patients with psoriasis, and the evaluation of combination therapies for difficult-to-treat disease. For axSpA, there continues to be the need to understand the role of interleukin-23 (IL-23) in pathogenesis and the genetic relationship of the IL-23-receptor polymorphism with other related systemic inflammatory diseases (eg, inflammatory bowel disease). A major unmet need in the OA field remains the need to develop the ability to reliably phenotype and stratify patients for inclusion in clinical trials. SLE experts identified a number of unmet needs within clinical trial design including the need for allowing endpoints that reflect pharmacodynamic/functional outcomes (eg, inhibition of type I interferon pathway activation; changes in urine biomarkers). Lastly, within SSc and vasculitis, there is a lack of biomarkers that predict response or disease progression, and that allow patients to be stratified for therapies. There remains a strong need to innovate clinical trial design, to identify systemic and tissue-level biomarkers that predict progression or response to therapy, endotype disease, and to continue developing therapies and therapeutic strategies for those with treatment-refractory disease. This document, based on expert consensus, should provide a roadmap for prioritising scientific endeavour in the field of rheumatology.

EULAR recommendations for the management of psoriatic arthritis with pharmacological therapies: 2023 update.

OBJECTIVE: New modes of action and more data on the efficacy and safety of existing drugs in psoriatic arthritis (PsA) required an update of the EULAR 2019 recommendations for the pharmacological treatment of PsA. METHODS: Following EULAR standardised operating procedures, the process included a systematic literature review and a consensus meeting of 36 international experts in April 2023. Levels of evidence and grades of recommendations were determined. RESULTS: The updated recommendations comprise 7 overarching principles and 11 recommendations, and provide a treatment strategy for pharmacological therapies. Non-steroidal anti-inflammatory drugs should be used in monotherapy only for mild PsA and in the short term; oral glucocorticoids are not recommended. In patients with peripheral arthritis, rapid initiation of conventional synthetic disease-modifying antirheumatic drugs is recommended and methotrexate preferred. If the treatment target is not achieved with this strategy, a biological disease-modifying antirheumatic drug (bDMARD) should be initiated, without preference among modes of action. Relevant skin psoriasis should orient towards bDMARDs targeting interleukin (IL)-23p40, IL-23p19, IL-17A and IL-17A/F inhibitors. In case of predominant axial or entheseal disease, an algorithm is also proposed. Use of Janus kinase inhibitors is proposed primarily after bDMARD failure, taking relevant risk factors into account, or in case bDMARDs are not an appropriate choice. Inflammatory bowel disease and uveitis, if present, should influence drug choices, with monoclonal tumour necrosis factor inhibitors proposed. Drug switches and tapering in sustained remission are also addressed. CONCLUSION: These updated recommendations integrate all currently available drugs in a practical and progressive approach, which will be helpful in the pharmacological management of PsA.

Differential properties of Janus kinase inhibitors in the treatment of immune-mediated inflammatory diseases.

Janus kinases (JAKs) are a family of cytosolic tyrosine kinases that regulate cytokine signal transduction, including cytokines involved in a range of inflammatory diseases, such as RA, psoriasis, atopic dermatitis and IBD. Several small-molecule JAK inhibitors (JAKis) are now approved for the treatment of various immune-mediated inflammatory diseases. There are, however, key differences between these agents that could potentially translate into unique clinical profiles. Each JAKi has a unique chemical structure, resulting in a distinctive mode of binding within the catalytic cleft of the target JAK, and giving rise to distinct pharmacological characteristics. In addition, the available agents have differing selectivity for JAK isoforms, as well as off-target effects against non-JAKs. Other differences include effects on haematological parameters, DNA damage repair, reproductive toxicity and metabolism/elimination. Here we review the pharmacological profiles of the JAKis abrocitinib, baricitinib, filgotinib, peficitinib, tofacitinib and upadacitinib.

Magnetic resonance imaging characteristics in patients with psoriatic arthritis and axial manifestations from the MAXIMISE cohort.

OBJECTIVE: The current analysis of the MAXIMISE trial was conducted to investigate the presence of post-inflammatory and degenerative spinal changes and inflammatory changes in spinal processes identified in baseline MRIs and their potential for predicting differential treatment effects in a cohort of PsA patients with axial manifestations. METHODS: Baseline spinal MRIs from the MAXIMISE trial were re-read to identify additional inflammatory (spinal process), post-inflammatory, and degenerative changes, and investigate the differential treatment effect of these imaging features using logistic regression modelling. RESULTS: In addition to bone marrow oedema assessed at primary analysis, spinal process inflammation and post-inflammatory changes evaluated by FAt Spondyloarthritis Spine Score were documented in 11.1% and 20.2% patients, respectively. At least one type of degenerative change was noted in 64% patients, with Pfirrmann grade ≥3 (51.1%) being the most common. Combining primary and re-read MRI findings, 67.1% of patients presented with inflammatory or post-inflammatory changes while 21.2% had degenerative changes alone. Although not statistically significant, post-inflammatory changes were associated with a trend for better efficacy outcomes in terms of ASAS20, ASAS40 and BASDAI50 responses; a trend for worse outcomes was observed in the presence of degenerative changes. CONCLUSION: The current analysis revealed the occurrence of additional inflammatory and post-inflammatory changes suggestive of axial PsA (axPsA) and a trend for better clinical outcomes for patients treated with secukinumab. These results elucidate the imaging characteristics and improve our current understanding of axPsA thereby supporting the interpretation of future trials.

A Good Response to Nonsteroidal Antiinflammatory Drugs Does Not Discriminate Patients With Longstanding Axial Spondyloarthritis From Controls With Chronic Back Pain.

OBJECTIVE: To compare the response to nonsteroidal antiinflammatory drugs (NSAIDs) in patients with longstanding axial spondyloarthritis (axSpA) and controls with back pain (nonspondyloarthritis [non-SpA]). METHODS: Consecutive outpatients with chronic back pain (axSpA or non-SpA), were prospectively recruited. Any previous NSAIDs were withdrawn 2 days before study start (baseline). Back pain was assessed using a numerical rating scale (NRS; range 0-10) starting at 2 hours after baseline and several times thereafter up to 4 weeks. "Any response" to NSAIDs was defined as improvement of back pain on the NRS > 2 units, and "good response" as improvement > 50%, compared to baseline. RESULTS: Among 233 patients included, 68 had axSpA (29.2%) and 165 had non-SpA back pain (70.8%). The mean age was 42.7 (SD 10.7) vs 49.3 (SD 11.1) years, symptom duration 15.1 (SD 11.1) years vs 14.6 (SD 11.9) years, and pain score 5.9 (SD 2.3) vs 6.3 (SD 2.0), respectively. Overall, of patients with axSpA or non-SpA back pain, 30.9% vs 29.1% of patients showed any response and 23.5% vs 16.4% of patients showed a good response after 4 weeks, respectively (P value not significant). No differences were found in the rapidity of response or between subgroups of patients based on demographics, including different stages of axSpA. CONCLUSION: No major differences in the response to NSAIDs were found between patients with axSpA and those with non-SpA with longstanding chronic back pain. The item in the Assessment of SpondyloArthritis international Society classification criteria on "response to NSAIDs" needs more study.

Efficacy and Safety of Tofacitinib in Ankylosing Spondylitis by Baseline C-Reactive Protein Level: Post Hoc Analysis of Phase 2/3 Clinical Trials.

OBJECTIVE: This post hoc analysis assessed baseline CRP impact on efficacy/patient-reported outcomes (PROs)/safety of tofacitinib in ankylosing spondylitis (AS). METHODS: Phase 2/Phase 3 data from patients with active AS were used. Endpoints (weeks 12/16/48) including Assessment of SpondyloArthritis International Society 20%/40% improvement (ASAS20/ASAS40), AS Disease Activity Score (ASDAS)-CRP low disease activity (ASDAS-CRP LDA), 50% improvement in Bath AS Disease Activity Index (BASDAI50), and PROs (pain/fatigue) were stratified by baseline CRP (mg/L): <5 (normal)/≥5 (elevated); and <10/≥10. Safety outcomes were evaluated by <5/≥5mg/L. RESULTS: Overall, 372 patients were included (69.6%, ≥5mg/L; 50.8%, ≥10mg/L). At baseline, in the <5mg/L group, more placebo-treated than tofacitinib-treated patients received concomitant non-steroidal anti-inflammatory drugs (NSAIDs)/sulfasalazine. Week 12 efficacy/PRO responses were generally higher for tofacitinib versus placebo, regardless of baseline CRP. The treatment effect (placebo-adjusted response) at week 12 was generally numerically higher in ≥5/≥10 versus <5/<10mg/L groups. Treatment-emergent adverse events (TEAEs) and 'all infections' incidence rates were numerically higher for tofacitinib versus placebo in patients with <5mg/L, but similar for tofacitinib versus placebo in patients with ≥5mg/L. CONCLUSION: Regardless of baseline CRP, tofacitinib was more efficacious versus placebo (week 12). The placebo-adjusted efficacy/PRO responses were generally numerically higher in patients with ≥5/10mg/L versus <5/10mg/L. The higher concomitant NSAID/sulfasalazine exposure may have improved efficacy responses in the baseline <5mg/L placebo group, and ultimately affected the tofacitinib treatment effect. Safety was consistent with previous studies of tofacitinib in AS, with numerically higher TEAEs and 'all infections' incidence rates for tofacitinib versus placebo in patients with <5mg/L.

Anti-TNF-α induced paradoxical psoriasis in patients with ankylosing spondylitis: a systematic review.

OBJECTIVES: The approval of TNF-a inhibitors (TNFi) was a breakthrough in the treatment of ankylosing spondylitis (AS). Although also effective in psoriasis, drug-related adverse events of onset of psoriasiform skin lesions - paradoxical psoriasis (PP) under TNFi have been reported. METHODS: We performed an electronic data search in MEDLINE via Pubmed and Cochrane library scientific databases from inception to January 2023, following the PRISMA guidelines. We assessed the distinct characteristics and frequency of risks for PP appearance in AS patients treated with different TNFi. RESULTS: PP was found in 0.5-1% of TNFi-treated AS patients and the latency period was 2-11 months. The safest TNFi in terms of PP induction was certolizumab, whereas the one most commonly associated with PP was infliximab. CONCLUSIONS: PP is an uncommon adverse reaction to TNFi treatment in AS patients and responds well to drug withdrawal. More large data studies need to be conducted though, to shed light on PP nature and management.

Patient clusters identified by machine learning from a pooled analysis of the clinical development programme of secukinumab in psoriatic arthritis, ankylosing spondylitis and psoriatic arthritis with axial manifestations.

OBJECTIVES: To identify patient clusters based on baseline demographics and clinical indicators. METHODS: Pooled baseline demographics and clinical data of secukinumab-treated patients from ten Phase III studies in psoriatic arthritis (PsA; FUTURE 1-5 and MAXIMISE), ankylosing spondylitis (AS; MEASURE 1-4), were analysed by machine learning (ML) algorithms. The longitudinal responses of secukinumab 300 mg versus 150 mg were investigated across the clusters and three clinical indicators of tender joints, swollen joints and enthesitis. RESULTS: 3907 patients were grouped into eight distinct clusters based on patient demographics and baseline clinical characteristics. Patients with PsA and axial manifestations (MAXIMISE) were overrepresented in clusters 6-8. Patients in cluster 6 (mean age 48 years; 46% male) were overweight with pronounced psoriasis, higher articular burden in knees, shoulders, elbows and wrists. Patients in cluster 7 (mean age 47 years; 53% male) were less overweight with lower polyarticular joint counts and tenderness of the joints of the feet, wrists and hands. Patients in cluster 8 were predominantly with AS (mean age 43 years; 64% male) with a mean body mass index of 27.3 kg/m2, oligoarthritis and high prevalence of spinal pain. Patients with PsA (FUTURE) were overrepresented in clusters 1-5. Longitudinal analysis showed improvements with secukinumab 300 mg versus 150 mg in clusters 6 and 8 for tender joint counts, and cluster 7 for swollen joint counts. CONCLUSIONS: PsA clusters obtained by ML in pooled dataset indicate phenotypical heterogeneity of patients with PsA and axial manifestations and overlapping features across the spondyloarthritis spectrum.

Prevalence of remission in patients with rheumatoid arthritis in daily clinical practice: long-term data from a tertiary care centre.

OBJECTIVES: We aimed to study remission rates in patients with RA in a tertiary care centre over a long-term observation period. METHODS: In a monocentric cohort study with a prospective and a retrospective part, adult RA patients were included. Patient's characteristics and outcome parameters were documented prospectively (clinical visit). Data of the initial visit (index visit) and date of first occurrence of remission were taken retrospectively from the hospital information system. Remission was defined as DAS28 <2.6 and sustained remission (SR) was defined as remission lasting >6 months. Logistic regression analysis was used to analyse factors associated with remission and SR. RESULTS: A total of 136 RA patients were included with retrospective data available over a period of 47.9 (18.9) months. One third already had erosions and severe limitations in physical function at baseline. The vast majority (n=109) of patients achieved a state of remission at least once over time (80.1%). At the clinical visit, 40 patients (29.4%) were in remission. Remission was achieved 14.9 months (13.8) after the index visit and by 54.1%, 23.9%, 13.8%, and 8.3% of patients within the first, second, third, and fourth year, respectively. SR was achieved by 65 patients (47.8%) within the observation period. CONCLUSIONS: Most patients achieved remission at least once within the observation period and almost 50% of patients also achieved SR. This study shows that the target of achieving remission should be constantly pursued, as we were able to show that even in the fourth year of treatment, patients still achieved remission.

[Patient-oriented optimization of the quality of care in a specialized outpatient clinic in a tertiary rheumatology center : A qualitative study]. / Patientenorientierte Optimierung der Versorgungsqualität in der ambulanten spezialfachärztlichen Versorgung (ASV) in einem tertiären rheumatologischen Zentrum : Eine qualitative Studie.

BACKGROUND: The adaptation of structures and processes in treatment procedures can contribute to increasing patient satisfaction and is the focus of patient-oriented quality assurance. OBJECTIVE: To identify patient satisfaction as well as needs, expectations and preferences with respect to care and, based on this, to formulate recommendations for action to optimize the quality of care at a large tertiary rheumatology center. MATERIAL AND METHODS: As part of a qualitative research approach, semi-structured patient interviews and a focus group interview consisting of physicians in rheumatology training in outpatient specialist care were conducted. The quality dimensions of Donabedian were recorded. The data material was evaluated and analyzed using the content-structuring qualitative content analysis according to Kuckartz with the MAXQDA evaluation software. RESULTS: Using 12 patient interviews and a focus group of 3 future rheumatologists, recommendations for action to optimize the quality of care were derived on the basis of the structural, process and outcome quality. There was a need for optimization in the areas of personnel management, internal practice processes, practice equipment and treatment processes in the outpatient clinic. CONCLUSION: The results from the patient interviews and the focus group revealed the aspects in need of optimization. The methodology and results of this study can serve as a reference point for analyses of other rheumatology clinics in order to improve the quality of care within the framework of patient-oriented quality management and continuous further development.

[German translation and linguistic validation of the modified short questionnaire to assess health-enhancing physical activity (mSQUASH) for patients with axial spondyloarthritis (axSpA)]. / Übersetzung und sprachliche Validierung des modifizierten-Short QUestionnaire to Assess Health-enhancing physical activity (mSQUASH) ins Deutsche für Patienten mit axialer Spondyloarthritis (axSpA).

BACKGROUND: Patients with axial spondyloarthritis (axSpA) often experience chronic pain and inflammation, resulting in physical impairments, reduced mobility and decreased physical activity. The modified short questionnaire to assess health-enhancing physical activity (mSQUASH) was developed to assess daily physical activity in patients with axSpA. OBJECTIVE: To translate, cross-culturally adapt and linguistically validate the original mSQUASH into German for patients with axSpA. METHODS: The original mSQUASH was translated from Dutch into German using a multistep process (Beaton method) with forward-backward translations into German by bilingual Dutch-German lay people and experts. Any remaining discrepancies were resolved by a scientific committee, resulting in a prefinal German version. Field testing with cognitive debriefing interviews with patients with axSpA from diverse backgrounds led to a final German version. RESULTS: Minor discrepancies, primarily related to formalities, semantic errors and syntax were found during translations. These were addressed, resulting in slight wording modifications. The prefinal German version was validated through cognitive debriefing by 10 patients with axSpA, confirming its linguistic validity and equivalence to the Dutch version. CONCLUSION: Overall, this study confirmed the final German mSQUASH as a comprehensive measurement instrument for daily physical activity. It can now be used as a patient-reported outcome by German patients with axSpA. This can enable cross-linguistic comparisons and expanding its utility across language barriers.

Survey on the working, training, and research conditions of resident physicians in internistic and rheumatological continuing education-BEWUSST.

BACKGROUND: Data on the training and continuing education situation of residents in the field of internal medicine and rheumatology are not available for Germany. For this reason, the Commission for Education and Training of the German Society of Rheumatology (DGRh) initiated the BEWUSST survey on the working, training and research conditions of residents in rheumatology. METHODS: A total of 102 questions on the topics of working conditions in everyday professional life, continuing medical education and training, compatibility of career and family, compatibility of work and research, perspectives as a rheumatologist and practical activities were included in an online questionnaire. RESULTS: A total of 102 participants took part in the survey. Of the respondents 48.1% were satisfied with their professional situation, 40.2% of the participants were supervised by a specialist mentor and 54.9% were working as scientists during their work as a physician. A compatibility of family and career was possible for 34.7%. After completion of the residency 52.9% of the respondents aspired to a combined clinical and outpatient activity. CONCLUSION: Half of the trainee rheumatologists are satisfied with their professional activities, although mentoring of the assistants in training should be further improved. With respect to the desired combined clinical and outpatient activity, the existing options should be expanded or new professional fields of activity should be established, so that the specialty remains attractive for the upcoming generations.

Immunological biomarkers in patients with radiographic axial spondyloarthritis, an exploratory longitudinal Swedish study.

Objectives There is a need for more specific biomarkers to diagnose and predict disease course in patients with axial spondyloarthritis (axSpA). This study aimed to study immunological plasma biomarkers, at different time-points in radiographic (r)-axSpA patients overall and stratified by sex and compare these biomarker pattern in r-axSpA patients concerning disease phenotypes and disease activity. Methods Plasma samples were analysed from r-axSpA patients at and prior (Pre-Backbone) inclusion in the Backbone study. Interferon gamma, interleukin-10, -17A, -17F, -22, -23, -6, MCP-1, TNF-α, VEGF-A, MIF, IgA anti-CD74, zonulin, ESR, hsCRP, white blood cell count, and blood lipids were measured. Results Biomarker pattern discriminated significantly between r-axSpA patients in Backbone and Pre-Backbone compared with controls. When stratifying by sex, it was possible to discriminate between male and female r-axSpA patients in Backbone vs controls and between male r-axSpA patients in pre-Backbone and controls. In Backbone, markers with high discriminative capacity were MIF, IgA anti-CD74, and MCP-1. In Pre-Backbone, IL-6, TNF-α, MIF, triglycerides, cholesterol, IL-10, and zonulin displayed high discriminative capacity. Conclusion Based on their temporal pattern and mutual relationship, we suggest studying MIF, IgA anti-CD74, and MCP-1 in depth, at more time points, to further elucidate disease-driving mechanisms in this complex disease.

What do we know about co-stimulatory and co-inhibitory immune checkpoint signals in ankylosing spondylitis?

Ankylosing spondylitis is the main entity of a family of inflammatory diseases affecting many musculoskeletal (sacroiliac joints, spine, and peripheral joints) and extra-musculoskeletal sites, termed spondyloarthritis. While it is debated whether disease onset is primarily driven by autoimmune or autoinflammatory processes, what is certain is that both innate and adaptive immune responses orchestrate local and systemic inflammation, which leads to chronic pain and immobility. Immune checkpoint signals are one key player in keeping the immune system in check and in balance, but their role in disease pathogenesis is still rather elusive. Therefore, we ran a MEDLINE search utilizing the PubMed platform for a variety of immune checkpoint signals in regard to ankylosing spondylitis. In this review, we summarize the experimental and genetic data available and evaluate the relevance of immune checkpoint signalling in the pathogenesis of ankylosing spondylitis. Markers such as PD-1 and CTLA-4 have been extensively studied and facilitate the concept of an impaired negative immune regulation in ankylosing spondylitis. Other markers are either neglected completely or insufficiently examined, and the data is conflicting. Still, some of those markers remain interesting targets to decipher the pathogenesis of ankylosing spondylitis and to develop new treatment strategies.

Efficacy and safety of non-pharmacological and non-biological interventions: a systematic literature review informing the 2022 update of the ASAS/EULAR recommendations for the management of axial spondyloarthritis.

OBJECTIVE: To update the evidence of non-biological treatments for axial spondyloarthritis (axSpA), as a basis for the 2022 Assessment of SpondyloArthritis international Society-European Alliance of Associations for Rheumatology (ASAS-EULAR) recommendations for the management of axSpA. METHODS: A systematic literature review (2016-2021) on efficacy and safety of non-pharmacological and non-biological pharmacological treatments was performed, up to 1 January 2022. The research question was formulated according to the PICO format: Population: adult patients with r-axSpA and nr-axSpA; Intervention: non-pharmacological and non-biological pharmacological treatments; Comparator: active comparator or placebo; Outcomes: all relevant efficacy and safety outcomes. Type of studies included were: randomised controlled trials (RCTs), observational studies (for efficacy of non-pharmacological treatments, and safety), qualitative studies. Cohen's effect size (ES) was calculated for non-pharmacological and risk ratio (RR) for pharmacological treatments. RESULTS: Of 107 publications included, 63 addressed non-pharmacological interventions, including education (n=8) and exercise (n=20). The ES for education on disease activity, function, mobility was small to moderate (eg. Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), ES: 0.06-0.59). Exercise had moderate to high ES on these outcomes (eg. BASDAI, ES: 0.14-1.43). Six RCTs on targeted synthetic disease-modifying antirheumatic drugs (DMARDs) showed efficacy of tofacitinib, upadacitinib and filgotinib (phase 2 only) in r-axSpA (range RR vs placebo for ASAS20: 1.91-3.10), while apremilast and nilotinib were not efficacious. Studies on conventional synthetic DMARDs (n=3), non-steroidal anti-inflammatory drugs (NSAIDs, n=8) and other drugs (n=12) did not provide new evidence on efficacy/safety (efficacy of NSAIDs confirmed; limited efficacy of short-term glucocorticoids in one RCT). CONCLUSIONS: Education, exercise and NSAIDs confirmed to be efficacious in axSpA. JAKi were proved efficacious in r-axSpA.
