Objectives The assessment of physical function is fundamental in the management of patients with idiopathic inflammatory myopathies (IIMs). We aimed to investigate the physical function of patients with IIMs compared with those with non-IIM autoimmune rheumatic diseases (AIRDs) utilizing Patient-Reported Outcome Measurement Information System (PROMIS) Physical Function (PF) data obtained in the COVAD study, an international self-reported e-survey assessing the safety of COVID-19 vaccines in AIRDs. Methods Demographics, AIRD diagnosis, disease activity, and PROMIS PF short form-10a data were extracted from the COVAD database. PROMIS PF-10a scores were compared between disease categories and stratified by disease activity. Factors affecting PROMIS PF-10a scores other than disease activity were identified by multivariable regression analysis in patients with inactive disease. Results A total of 1057 IIM patients, 3635 non-IIM AIRD patients and 3981 healthy controls (HCs) responded to the COVAD e-survey from April to August 2021. Using a binomial regression model, the predicted mean of PROMIS PF-10a scores was significantly lower in IIM patients compared with non-IIM AIRD patients or HCs [36.3 (95% CI 35.5, 37.1) vs 41.3 (95% CI 40.2, 42.5) vs 46.2 (95% CI 45.8, 46.6), P Conclusion Physical function is significantly impaired in IIMs compared with non-IIM AIRDs or HCs, even in patients with inactive disease. Our study highlights a critical need for better strategies to minimize functional disability in patients with IIMs.

Objectives To explore current management practices for PMR by general practitioners (GPs) and rheumatologists including implications for clinical trial recruitment. Methods An English language questionnaire was constructed by a working group of rheumatologists and GPs from six countries. The questionnaire focused on: 1: Respondent characteristics; 2: Referral practices; 3: Treatment with glucocorticoids; 4: Diagnostics; 5: Comorbidities; and 6: Barriers to research. The questionnaire was distributed to rheumatologists and GPs worldwide via members of the International PMR/Giant Cell Arteritis Study Group. Results In total, 394 GPs and 937 rheumatologists responded to the survey. GPs referred a median of 25% of their suspected PMR patients for diagnosis and 50% of these were returned to their GP for management. In general, 39% of rheumatologists evaluated patients with suspected PMR >2 weeks after referral, and a median of 50% of patients had started prednisolone before rheumatologist evaluation. Direct comparison of initial treatment showed that the percentage prescribing >25 mg prednisolone daily for patients was 30% for GPs and 12% for rheumatologists. Diagnostic imaging was rarely used. More than half (56%) of rheumatologists experienced difficulties recruiting people with PMR to clinical trials. Conclusion This large international survey indicates that a large proportion of people with PMR are not referred for diagnosis, and that the proportion of treatment-naive patients declined with increasing time from referral to assessment. Strategies are needed to change referral and management of people with PMR, to improve clinical practice and facilitate recruitment to clinical trials.

Background The use of social media in health care may serve as a beneficial tool for education, information dissemination, telemedicine, research, networking, and communications. To better leverage the benefits of social media, it is imperative to understand the patterns of its use and potential barriers to its implementation in health care. A previous study in 2016 that investigated social media use among young clinical rheumatologists (≤45 years) and basic scientists showed that there was substantial social media use among them for social and professional reasons. However, there is a limited inquiry into social media use in different areas of rheumatology, such as spondyloarthritis. Objective We aimed to explore the motivations, barriers, and patterns of social media use among an international group of experts in spondyloarthritis. Methods We distributed a web-based survey via email from March 2021 to June 2021 to 198 members of the Assessment of Spondyloarthritis International Society. It contained 24 questions about demographic characteristics, patterns of current social media use, and perceptions of utility. Univariable and multivariable logistic regression analyses were performed to identify the characteristics associated with use trends. Results The response rate was 78.8% (156/198). Of these, 93.6% (146/156) of participants used at least one social media platform. Apart from internet-based shopping and entertainment, the use of social media for clinical updates (odds ratio [OR] 6.25, 95% CI 2.43-16.03) and research updates (OR 3.45, 95% CI 1.35-8.78) were associated with higher social media consumption. Among the respondents, 66% (103/156) used social media in a work-related manner. The use of social media for new web-based resources (OR 6.55, 95% CI 2.01-21.37), interaction with international colleagues (OR 4.66, 95% CI 1.21-17.90), and establishing a web-based presence (OR 4.05, 95% CI 1.25-13.13) were associated with higher levels of consumption for work-related purposes. Time investment, confidentiality concerns, and security concerns were the top 3 challenges to a wider adoption of social media. Conclusions Most respondents (103/156, 66%) use social media in a work-related manner. Professional development, establishing a web-based presence, and international collaboration were associated with higher use. Challenges to social media adoption should be addressed to maximize its benefits.

COVID-19; Registries; Vaccination COVID-19; Registros; Vacunación COVID-19; Registres; Vacunació Vaccine hesitancy is considered a major barrier to achieving herd immunity against COVID-19. While multiple alternative and synergistic approaches including heterologous vaccination, booster doses, and antiviral drugs have been developed, equitable vaccine uptake remains the foremost strategy to manage pandemic. Although none of the currently approved vaccines are live-attenuated, several reports of disease flares, waning protection, and acute-onset syndromes have emerged as short-term adverse events after vaccination. Hence, scientific literature falls short when discussing potential long-term effects in vulnerable cohorts. The COVAD-2 survey follows on from the baseline COVAD-1 survey with the aim to collect patient-reported data on the long-term safety and tolerability of COVID-19 vaccines in immune modulation. The e-survey has been extensively pilot-tested and validated with translations into multiple languages. Anticipated results will help improve vaccination efforts and reduce the imminent risks of COVID-19 infection, especially in understudied vulnerable groups.

Objectives The COVID-19 vaccination in autoimmune diseases (COVAD) study aimed to assess short-term COVID-19 vaccination-related adverse events (AEs) in RA patients. Methods An online self-reported questionnaire (March–December 2021) was used to capture data related to COVID-19 vaccination-related AEs in RA, other autoimmune rheumatic diseases (AIRDs) (excluding RA and inflammatory myositis), non-rheumatic autoimmune diseases (nrAIDs) and healthy controls (HCs). Descriptive and multivariable regression analyses were performed. Results Of the 9462 complete respondents, 14.2% (n = 1347) had been diagnosed with RA; they had a mean (s.d.) age of 50.7 (13.7) years, 74.2% were women and 49.3% were Caucasian. In total, 76.9% and 4.2% of patients with RA reported minor and major AEs, respectively. Patients with active and inactive RA had similar AE and hospitalization frequencies. Overall, AEs were reported more frequently by BNT162b2 and mRNA-1273 recipients and less frequently by BBV152 recipients compared with the rest. Major AE and hospitalization frequencies were similar across recipients of different vaccines. Patients receiving methotrexate and hydroxychloroquine reported fewer minor AEs than those patients not on them. Compared with HCs and patients with other AIRDs, patients with RA reported similar total AEs, overall minor AEs, and hospitalizations. Compared with nrAIDs, patients with RA reported lower frequencies of overall AEs, minor AEs (both odds ratio [OR] = 0.7; 95% CI: 0.5, 0.9), and injection site pain (OR = 0.6; 95% CI: 0.5, 0.8) with similar major AE and hospitalization frequencies. Conclusion Despite the differences in AE frequency across different COVID-19 vaccines, all were well tolerated in patients with RA and were comparable to HCs, providing reassurance as to the safety of COVID-19 vaccination.

Objectives The aim of this study was to investigate the association between individual-level and country-level socio-economic (SE) factors and health outcomes across SpA phenotypes. Methods Patients with axial SpA (axSpA), peripheral SpA (pSpA) or PsA from the ASAS-perSpA study (in 23 countries) were included. The effect of individual-level (age, gender, education and marital status) and country-level [e.g. Gross Domestic Product (GDP)] SE factors on health outcomes [Ankylosing Spondylitis Disease Activity Score (ASDAS) ≥ 2.1, ASDAS, BASFI, fatigue and the Assessment of SpondyloArthritis international Society Health Index (ASAS-HI)] was assessed in mixed-effects models adjusted for potential confounders. Interactions between SE factors and disease phenotype were tested. A mediation analysis was conducted to explore whether the impact of country-level SE factors on ASDAS was mediated through biologic/targeted synthetic (b/ts) DMARD uptake. Results In total, 4185 patients (61% males, mean age 45) were included (65% axSpA, 25% PsA, 10% pSpA). Female gender [β= 0.14 (95% CI: 0.06, 0.23)], lower educational level [β = 0.35 (0.25, 0.45)) and single marital status [β = 0.09 (0.01, 0.17)] were associated with higher ASDAS. Living in lower GDP countries was also associated with higher ASDAS [β = 0.39 (0.16, 0.63)], and 7% of this association was mediated by b/tsDMARD uptake. Higher BASFI was similarly associated with female gender, lower education and living alone, without the effect of country-level SE factors. Female gender and lower educational level were associated with worse ASAS-HI, while more fatigue was associated with female gender and higher country-level SE factors [lower GDP, β = −0.46 (−0.89 to −0.04)]. No differences across disease phenotypes were found. Conclusions Our study shows country-driven variations in health outcomes in SpA, independently influenced by individual-level and country-level SE factors and without differences across disease phenotypes.

Objectives The primary objective was to compare the clinical characteristics of SpA patients with and without root joint disease (RJD+ and RJD–). The secondary objectives were to compare the prevalence of RJD across various SpA subtypes and in different world regions, and to compare the SpA axial severity and SpA burden between RJD+ and RJD–. Methods This is a post hoc analysis of the Assessment of Spondyloarthritis International Society PerSpA study (PERipheral involvement in SpondyloArthritis), which included 4465 patients with SpA [axial (axSpA), peripheral (pSpA), PsA, IBD, reactive and juvenile] according to the rheumatologist’s diagnosis. RJD was defined as the ‘ever’ presence of hip or shoulder involvement related to SpA, according to the rheumatologist. Patient characteristics were compared between RJD+ and RJD–. Multivariable stepwise binary logistic regression analyses were conducted to identify factors associated with ‘RJD’, ‘hip’ and ‘shoulder’ involvement. Results RJD was significantly associated with the SpA main diagnosis (highest in pSpA), a higher prevalence of HLA-B27 positivity, enthesitis, tender and swollen joints, CRP, conventional synthetic DMARDs, loss of lumbar lordosis and occiput-wall distance >0. RJD was more prevalent in Asia, and occurred in 1503 patients (33.7%), with more hip (24.2%) than shoulder (13.2%) involvement. Hip involvement had a distinct phenotype, similar to axSpA (including younger age at onset, HLA-B27 positivity), whereas shoulder involvement was associated with features of pSpA (including older age at onset). Conclusion RJD+ SpA patients had a distinctive clinical phenotype compared with RJD–. Hip involvement, based on the rheumatologist’s diagnosis, was more prevalent than shoulder involvement and was clinically distinct.

Objectives: The primary objective was to develop an educational video to teach patients with rheumatoid arthritis (RA) self-assessment of their disease activity. Secondary objectives were to validate the video, identify the challenges in producing it, and the responses to these challenges. Methods: Rheumatologists from 7 Middle Eastern Arab countries (MEAC) discussed unmet needs in the education of patients with RA. They reviewed pre-existing educational audiovisual material and drafted the script for a new video in Arabic. The video was produced in collaboration with a technical team, then validated by patients using a standardized interview. At each step of production, challenges were identified. Results: Twenty-three rheumatologists from MEAC identified unmet needs in patients’ education. A video was produced, explaining the concepts of treat-to-target and showing a patient performing self-assessment using DAS-28. Sixty-two patients were interviewed for validation and found the video to be useful and easy to understand, albeit not replacing the physician’s visit. Most common challenges encountered included acceptance of patient empowerment, agreement on DAS-28 as composite measure, production of a comprehensible written Arabic text, and addressing the population cultural mix. Conclusion: Despite challenges, the video was well accepted among patients and can be used for clinical and research purposes. It is particularly useful in pandemic periods where social distancing is recommended.

Diagnosing peripheral spondyloarthritis (pSpA) remains a significant challenge due to the lack of specific disease biomarkers and the overlap with other SpA subtypes, mainly psoriatic arthritis (PsA), which represents a diagnostic challenge particularly in the absence of skin psoriasis (PsAsine psoriase). This narrative review aimed to compare the epidemiology, genetic susceptibility, pathophysiology, classification criteria, disease phenotype and burden, and therapeutic guidelines between patients diagnosed with pSpA and those with PsAsine psoriase,to determine if the two entities should be considered jointly or distinctly. Globally, pSpA appears to be more inclusive compared with PsAsine psoriase. Areas of similarities include age of onset, number of joints involved and prevalence of axial involvement. However, patients with pSpA have a male gender predominance, a higher prevalence of HLA-B27, enthesitis and involvement of large joints of the lower limbs, whereas patients with PsAsine psoriasehave a higher prevalence HLA-Cw6, dactylitis and involvement of hand distal interphalangeal joints. Therefore, the difference between pSpA and PsAsine psoriasegoes beyond semantics. The few dissimilarities should drive scientific efforts to reach a better characterisation of pSpA as an individual disease. Accordingly, randomised clinical trials should target patients with well-defined pSpA to identify effective therapies in this population.

The association between ambient air pollution and several health conditions, including dermatologic disorders, has been heavily investigated. The mechanism involves an interplay of oxidative stress, inflammation and altered gene expression. Our study aims to investigate the association between air pollution and urticaria, an association not thoroughly investigated in the literature. Prospective data collection was performed during 2012 from emergency department (ED) medical records. Air pollution and meteorological data were obtained from Air Quality Research Unit stations situated close to each hospital. Stratification by age group was performed. Distributed lag model and generalized additive model analysis was performed. Relative risk (RR) and their 95% confidence intervals for ED visits diagnosed with urticaria associated with a 10-unit increase in PM2.5 and PM10 concentrations from reference value were calculated. Statistically significant associations were observed at lag 2 and lag 3 for individuals younger than 16 years of age. Statistically significant associations were not demonstrated for other age groups or at different lags. These findings demonstrate that air pollution is associated with increased risk of developing or experiencing manifestations of urticaria, particularly among children and adolescents.

The management of axial spondyloarthritis (axSpA) is challenging worldwide, and the particular challenges shared by North Africa and the Middle East are mainly related to early diagnosis and standardized management. We believe there are several reasons for these challenges, including: (a) limited awareness of the disease manifestations and prevalence in the region among physicians; (b) the concept of nonradiographic axSpA, while accepted with some difficulty by the rheumatology community, may not be well understood by the referring primary care physicians; (c) access to, and training in magnetic resonance imaging varies greatly between countries in the North Africa and Middle East region, and this may have a large impact on early diagnosis; (d) country‐specific treatment guidelines are unavailable; and (e) economic and cultural factors influence patients’ attempts to seek and continue treatment. In this review, we will discuss the prevalence of axSpA in North Africa and the Middle East, as well as the challenges to diagnose and treat patients in this region. As rheumatologists practicing in North Africa and the Middle East, we also provide suggestions to assist physicians, other healthcare professionals, and researchers in facilitating early, accurate diagnosis and treatment of axSpA.

Aim To evaluate the impact of the coronavirus disease 2019 pandemic (COVID-19) on the access to rheumatology care for patients with chronic rheumatic diseases (CRD) in the Arab countries. Method A web-based cross-sectional survey was designed by the Arab Adult Arthritis Awareness group (AAAA) consisting of 16 rheumatologists representing countries from the Arab League of Associations for Rheumatology (ArLAR) and was validated by the ArLAR scientific committee. The survey was disseminated online through social media and patients' association channels between May 8 and May 22, 2020. The steering committee developed recommendations to improve the care of patients with CRD during the COVID-19 pandemic. Results A total of 2163 patients were included in the analysis; 72% were female; mean age was 40 years (SD 11.9). The Levant, the Gulf, and North Africa contributed almost equally to the sample. The pandemic had a significant negative impact on rheumatology visits in 82% of cases, access to hydroxychloroquine (47%), and chronic medication persistency (28%). The negative impact on rheumatology visits was associated with female gender, country, medication non-persistency, isolation due to COVID-19, and impact on mental health. Sixty-one patients (2.8%) stated that they had COVID-19, 5% said that a close contact was infected, and 47% were in isolation because of COVID-19. Conclusion The current study highlights the deleterious consequences of the COVID-19 pandemic on the continuity of rheumatology care. Therefore, an action plan, including establishing a telemedicine platform, securing drug availability, and promoting medication persistence through the appropriate communication channels, is strongly recommended.

Resume Le retentissement fonctionnel dans la spondyloarthrite axiale est lie a la progression structurale causee par la maladie, qui contribue ainsi largement a son retentissement global et represente un defi majeur pour la prise en charge. Le diagnostic precoce au tout premier stade du processus inflammatoire permet d’ameliorer le controle et la prise en charge de la maladie. L’histoire naturelle des spondyloarthrites axiales est desormais mieux comprise grâce aux donnees de l’imagerie et du suivi a long terme, mais egalement a l’identification de certains facteurs predictifs de la progression structurale. Les anti-inflammatoires non-steroidiens (AINS) representent le traitement de premiere ligne de la spondyloarthrite axiale, cependant leur impact sur la progression structurale reste tres debattu. Les DMARD (traitements de fond) biologiques, tels que les anti-TNF, ont recemment montre un effet de ralentissement sur l’atteinte radiographique apres plusieurs annees de traitement tandis que les premieres donnees sur les inhibiteurs de l’IL-17 ont ete jugees positives. De nouveaux traitements sont en cours d’evaluation et affichent des resultats encourageants concernant leur effet sur l’evolution de la maladie. Cette revue resume les facteurs predictifs de progression radiographique chez les patients atteints de spondyloarthrite axiale et les donnees probantes sur l’efficacite structurale des traitements disponibles.

Functional disability in axial spondyloarthritis is related to the structural progression caused by the disease, thus largely contributing to its global burden and still representing a major challenge in management. Diagnosis at an early inflammatory stage of the disease is the hallmark for a better disease control and management. The natural history of axial spondyloarthritis is now better understood with imaging studies and long-term follow-up data, with some predictive factors for structural progression being identified. Non-steroidal anti-inflammatory drugs are still considered as the first line treatment for axial spondyloarthritis, however, their impact on structural progression is conflicting. Recent data on biologic disease-modifying anti-rheumatic drugs, such as tumor necrosis factor inhibitors have shown significant retardation of radiographic damage after several years of treatment, while first data with interleukin-17 inhibitors were also positive. Novel emerging drugs are being evaluated with promising results on halting disease progression. This review summarizes the predictors of radiographic progression in patients with axial spondyloarthritis as well as the current evidence on the effect of available treatments on structural progression.

BACKGROUND The use of social media in healthcare may serve as a beneficial tool for education, information dissemination, telemedicine, research, networking and communications.

It contained 24 questions about demographic characteristics, patterns of current social media usage and perceptions of utility. Univariable and multivariable logistic regression analyses were performed to identify characteristics associated with usage patterns. RESULTS The response rate was 78.8% (n=156). Of these, 146 (93.6%) used at least one social media platform. Apart from online shopping and entertainment, usage of social media for clinical updates (OR: 6.25, 95% CI: 2.43 – 16.03) and research updates (OR: 3.45, 95% CI: 1.35 – 8.78) were associated with higher social media consumption. Among the respondents, 103 (66.0%) utilised it in a work-related manner. Usage of social media for new online resources (OR: 6.55, 95% CI: 2.01 – 21.37), interaction with international colleagues (OR: 4.66, 95% CI: 1.21 – 17.90) and establishing an online presence (OR: 4.05, 95% CI: 1.25 – 13.13) were associated with higher levels of consumption for work-related purposes. Time investment, confidentiality concerns and security concerns were the top 3 challenges to a wider adoption of social media. CONCLUSIONS Majority of respondents (66.0%) utilise social media in a work-related manner. Professional development, establishing an online presence and international collaboration were associated with higher usage. Challenges to social media adoption should be addressed to maximise its benefits.

Objectives COVID-19 vaccines have been proven to be safe in the healthy population. However, gaps remain in the evidence of their safety in patients with systemic autoimmune and inflammatory disorders (SAIDs). COVID-19 vaccination-related adverse events (AEs) in patients with SAIDs and healthy controls (HC) seven days post-vaccination were assessed in the COVAD study, a patient self-reported cross-sectional survey. Methods The survey was circulated in early 2021 by >110 collaborators (94 countries) to collect SAID details, COVID-19 vaccination details and 7-day vaccine AEs, irrespective of respondent vaccination status. Analysis was performed based on data distribution and variable type. Results Ten thousand nine hundred respondents [median (interquartile range) age 42 (30–55) years, 74% females and 45% Caucasians] were analysed; 5867 patients (54%) with SAIDs were compared with 5033 HCs. Seventy-nine percent had minor and only 3% had major vaccine AEs requiring urgent medical attention (but not hospital admission) overall. Headache [SAIDs = 26%, HCs = 24%; odds ratio (OR) = 1.1 (95% CI: 1.03, 1.3); P = 0.014], abdominal pain [SAIDs = 2.6%, HCs = 1.4%; OR = 1.5 (95% CI: 1.1, 2.3); P = 0.011], and dizziness [SAIDs = 6%, HCs = 4%; OR = 1.3 (95% CI: 1.07, 1.6); P = 0.011], were slightly more frequent in SAIDs. Overall, major AEs [SAIDs = 4%, HCs = 2%; OR = 1.9 (95% CI: 1.6, 2.2); P Conclusion Vaccination against COVID-19 is safe in SAID patients. SAIDs were at a higher risk of major AEs than HCs, though absolute risk was small. There are small differences in minor AEs between vaccine types in SAID patients.

BackgroundTelehealth use is increasing and will undeniably continue to play a role beyond the COVID-19 era. Best practice guidelines (BPG) for telehealth add credibility, standardize approaches, facilitate reimbursement, and decrease liability.ObjectivesTo develop BPG for the use of Telehealth In Rheumatology in the Arab region, to identify the top barriers and facilitators of telehealth in the Arab region, and to provide rheumatologists with a practical toolkit for the implementation of telehealth.MethodsGuidelines were drafted by a core steering committee from the Arab League of Associations for Rheumatology (ArLAR) after performing a literature search. A multidisciplinary task force (TF), including 18 rheumatologists, 2 patients, and 2 regulators from 15 Arab countries, assessed the BPG using 3 rounds of anonymous online voting by modified Delphi process. The voting on barriers and facilitators was performed through one voting round. The toolkit was developed based on available literature and discussions during the Delphi rounds.ResultsFour General Principles and twelve Statements were formulated. All statements reached >80% consensus. A teleconsultation was specifically defined for the purpose of these guidelines. The concept of choice in telehealth was highlighted, emphasizing patient confidentiality, medical information security, rheumatologist’s clinical judgment, and local jurisdictional regulations. The top barrier for telehealth was the concern about the quality of care. The toolkit emphasized technical aspects of teleconsultation and proposed a triage system.ConclusionsThe ArLAR BPG provides rheumatologists with a series of strategies about the most reliable, productive, and rational approaches to apply telehealth.Article SummaryStrengths and limitations of this studyBest practice guidelines (BPG) the use of Telehealth In Rheumatology in the Arab region were developed herein under the umbrella of the Arab League of Associations for Rheumatology (ArLAR)A teleconsultation was specifically defined for the purpose of these guidelinesThe concept of choice in telehealth was highlighted, emphasizing patient confidentiality, medical information security, rheumatologist’s clinical judgment, and local jurisdictional regulationsThe top barrier for telehealth was the concern about the quality of careThe ArLAR BPG provides rheumatologists with a series of strategies about the most reliable, productive, and rational approaches to apply telehealth in the rheumatology clinic

Musculoskeletal disorders remain a major problem in hemodialysis patients. The aim of the study was to estimate the prevalence of musculoskeletal manifestations in hemodialysis patients and identify disease cluster profiles. We performed a cross-sectional study including all adult patients in the hemodialysis unit at Hotel-Dieu de France Hospital. We collected demographic characteristics, musculoskeletal symptoms, biologic parameters, and treatments. Musculoskeletal disorders were classified by a rheumatologist into predefined diagnostic categories. Prevalence was presented, and a cluster analysis was performed. Eighty-nine patients were included, mean age was 67.5 ± 12 years, and 43.8% were female. Dialysis vintage was 5.7 ± 5.37 years. Musculoskeletal symptoms were reported by 76.4% of the patients. Pain was the most frequent symptom (44.9%). The main diagnoses were osteoarthritis (53.9%) and fracture (27%). Musculoskeletal symptoms and disorders were significantly associated with dialysis vintage and age. Cluster analysis identified three patient profiles: younger with low calcium levels, younger but long dialysis vintage with osteoarthritis and carpal tunnel syndrome, and older with long dialysis vintage and fractures. The prevalence of musculoskeletal manifestations is high in the hemodialysis population and increases with dialysis vintage. Musculoskeletal disorders cluster according to age and dialysis vintage. Key Points• Musculoskeletal symptoms are highly prevalent among hemodialysis patients (76.4%).• All musculoskeletal disorders are associated with dialysis vintage and age.• Three clusters are identified among hemodialysis patients: young with low calcium levels, young but long dialysis vintage with osteoarthritis and carpal tunnel syndrome and old with long dialysis vintage with fractures.

The Spondyloarthritis (SpA) represents a group of rheumatic inflammatory entities that share clinical, laboratory and imaging features, including Psoriatic Arthritis (PsA). Axial involvement may occur in up to 50% of patients with PsA (axPsA), causing inflammatory back pain, stiffness and changes on imaging. Whether axial SpA (axSpA) with psoriasis represents a distinct entity than axPsA is a matter of debate, since similarities and differences have been reported in terms of clinical expression and imaging. Patients with radiographically axPsA show lower prevalence of inflammatory b ack pain, lumbar and buttock pain in comparison with axSpA. In addition, imaging features differ between axPsA and axSpA, with less sacroiliitis in axPsA and more asymmetrical, chunky syndesmophytes which are predominant at the cervical spine location. Data on treatment efficacy and management recommendations are extrapolated from studies on axSpA, and only one published randomized clinical trial is dedicated specifically to axPsA to date.

Background: Health information records in many countries, especially developing countries, are still paper based. Compared to electronic systems, paper-based systems are disadvantageous in terms of data storage and data extraction. Given the importance of health records for epidemiological studies, guidelines for effective data cleaning and sorting are essential. They are, however, largely absent from the literature. The following paper discusses the process by which an algorithm was developed for the cleaning and sorting of a database generated from emergency department records in Lebanon. Design and methods: Demographic and health related information were extracted from the emergency department records of three hospitals in Beirut. Appropriate categories were selected for data categorization. For health information, disease categories and codes were selected according to the International Classification of Disease 10th Edition. Results: A total of 16,537 entries were collected. Demographic information was categorized into groups for future epidemiological studies. Analysis of the health information led to the creation of a sorting algorithm which was then used to categorize and code the health data. Several counts were then performed to represent and visualize the data numerically and graphically. Conclusions: The article describes the current state of health information records in Lebanon and the associated disadvantages of a paper-based system in terms of storage and data extraction. Furthermore, the article describes the algorithm by which health information was sorted and categorized to allow for future data analysis using paper records. Significance for public health In our protocol, we explain the process by which health information collected from paper-based records were analyzed to develop an algorithm to allocate appropriate ICD 10 disease codes and categories to each entry. The algorithm allows for the sequential analysis of the information present and serves to overcome the issue of incomplete records. This is especially relevant in developing countries where paper-based records are highly relied upon, noting that our protocol has already been applied to a study in the Ivory Coast. The protocol allows for a health information database to be cleaned and sorted for research in environmental, social and occupational health. Furthermore, since data cleaning and sorting protocols are sparse, it is crucial to establish a standardized tool to enhance the quality of the conducted research.

Little is known about the prevalence, phenotype, and burden of peripheral spondyloarthritis (pSpA). The objective of the study is to compare the phenotype and burden of disease of pure pSpA to that of pure psoriatic arthritis (PsA), pure axial SpA (axSpA), and combined forms of SpA.This is a post hoc analysis of 4,185 patients from the cross-sectional ASAS-Peripheral involvement in SpA (PerSpA) study. Patients were approached in 2 ways: the first approach was based on the rheumatologist's diagnosis (diagnostic approach) and the second one was based on the fulfillment of ASAS or CASPAR classification criteria (classification criteria approach). Demographics, disease phenotype, and burden were compared among pure pSpA, PsA, axSpA, and the combined forms.The proportion of pSpA was 31.5% of SpA using the classification criteria approach and 10.3% using the diagnostic approach. pSpA was pure (i.e. without axSpA or PsA) in 16.8% of pSpA using the criteria, and in 62.3% using the diagnostic approach. Using classification criteria and diagnostic approach, respectively, pure pSpA patients had a high prevalence of peripheral joint disease (86 and 96%), synovitis (76 and 91%), and enthesitis (57 and 55%), a positive HLA-B27 in 65 and 59%, a high C-Reactive Protein level in 51% and inflammatory back pain in 52 and 42%. However, compared to pure PsA and pure axSpA, they had a significantly higher disease burden, but lower use of biologics using both approaches.The proportion of pSpA varies when using the classification criteria or the diagnostic approach. pSpA occurred in a pure form less frequently than PsA and axSpA and had intermediate features but a higher disease burden.The PerSpA main study has been conducted under the umbrella of ASAS thanks to unrestricted grants from PFIZER, LILLY, ABBVIE, NOVARTIS, UCB, JANSSEN, MERCK.

ObjectivesTo characterise peripheral musculoskeletal involvement in patients with spondyloarthritis (SpA) including psoriatic arthritis (PsA), across the world.MethodsCross-sectional study with 24 participating countries. Patients with a diagnosis of axial SpA (axSpA), peripheral SpA (pSpA) or PsA according to their rheumatologist were included. The investigators were asked which diagnosis out of a list of six (axSpA, PsA, pSpA, inflammatory bowel disease-associated SpA, reactive arthritis or juvenile SpA (Juv-SpA)) fitted the patient best. Peripheral manifestations (ie, peripheral joint disease, enthesitis, dactylitis and root joint disease), their localisation and treatments were evaluated.ResultsA total of 4465 patients were included (61% men, mean age 44.5 years) from four geographic areas: Latin America (n=538), Europe plus North America (n=1677), Asia (n=975) and the Middle East plus North Africa (n=1275). Of those, 78% had ever suffered from at least one peripheral musculoskeletal manifestation; 57% had peripheral joint disease, 44% had enthesitis and 15% had dactylitis. Latin American had far more often peripheral joint disease (80%) than patients from other areas. Patients with PsA had predominantly upper limb and small joint involvement (52%).Hip and shoulder involvement was found in 34% of patients. The prevalence of enthesitis ranged between 41% in patients with axSpA and 65% in patients with Juv-SpA. Dactylitis was most frequent among patients with PsA (37%).ConclusionThese results suggest that all peripheral features can be found in all subtypes of SpA, and that differences are quantitative rather than qualitative. In a high proportion of patients, axial and peripheral manifestations coincided. These findings reconfirm SpA clinical subtypes are descendants of the same underlying disease, called SpA.

The coronavirus disease-2019 (COVID-19) pandemic continues to be a cause of unprecedented global morbidity and mortality. Whilst COVID-19 vaccination has emerged as the only tangible solution to reducing poor clinical outcomes, vaccine hesitancy continues to be an obstacle to achieving high levels of vaccine uptake. This represents particular risk to patients with autoimmune diseases, a group already at increased risk of hospitalization and poor clinical outcomes related to COVID-19 infection. Whilst there is a paucity of long-term safety and efficacy data of COVID-19 vaccination in patients with autoimmune diseases, the current evidence strongly suggests that the benefits of vaccination outweigh the risks of adverse effects and disease flares. Herein, we report the protocol of the COVID-19 Vaccination in Autoimmune Diseases (COVAD) study, an ongoing international collaborative study involving 29 countries and over 110 investigators.
