Show moreAim: To identify all possible definitions of "early SpA" employed in the literature, including "early axial SpA (axSpA)" and "early peripheral SpA (pSpA)".Methods: A systematic literature review was conducted in Medline, EMBASE and the Cochrane Library for studies that included any mention of "early SpA" or its subtypes. The proportion of studies including a definition was calculated, and the different definitions were assessed.Results: Out of 9651 titles identified, 336 publications reporting data from 183 studies were included. Over time, an increasing number of publications were identified. In total, 114 (62%) studies reported a specific definition: 33% of them based it on symptom duration, 31% on radiographic damage, 28% on disease duration, 5% on both symptom/disease duration and radiographic damage, and 3% on other aspects. Overall, 61 (33%) studies included the term "early axSpA", whereas 60 (33%) included "early ankylosing spondylitis (AS)". Regarding the studies that referred to "early axSpA", the most used definition was symptom/disease duration <5 years, whereas for "early AS" was symptom/disease duration <10 years. After 2010, the definition of "early axSpA" based on the absence of radiographic sacroiliitis was less used compared to before 2010 (17% vs 38%).Conclusion: Over time, the term "early SpA" and its subtypes is increasingly used. More than one third of the studies did not include a definition of the term and the studies reporting one showed a large heterogeneity. These results emphasize the need for a standardised definition of early SpA. Show less

Show moreObjectives To investigate the associations between MRI detected vertebral corner inflammation (VCI) and vertebral corner fat deposition (VCFD) on whole spine low-dose CT scan (ldCT) detected syndesmophyte formation and growth. Methods Patients from the Sensitive Imaging in Ankylosing Spondylitis cohort underwent MRI (baseline, 1 year and 2 years) and ldCT (baseline and 2 years). MR images were scored by three readers for VCI and VCFD, MRI patterns were defined by presence of VCI and/or VCFD over 2 years. LdCT images were scored by two central readers for presence and size of syndesmophytes and change was calculated for new or new/grown syndesmophytes. Multilevel generalised estimated equations were used to test the associations between VCI and VCFD and syndesmophyte development. Results Fifty radiographic patients with axial spondyloarthritis were included (mean age 49 years, 86% male, 78% HLA-B27+). Absence of both VCI and VCFD protected against syndesmophyte development (ORs 0.36-0.37). Presence of VCI and/or VCFD increased the risk of syndesmophyte development (ORs 1.73-2.60). Out of all corners with a new or new/grown syndesmophyte, 47% of corners according to reader 1 and 44% according to reader 2 had neither VCI nor VCFD preceding the bone formation. Conclusions VCI and VCFD were positively associated with syndesmophyte development. This has been shown for the first time for syndesmophytes detected on ldCT and also in the thoracic spine. However, almost half of all bone formation occurred in corners without VCI or VCFD, suggesting the presence of these lesions in yearly MRIs does not fully clarify the development of syndesmophytes.

Show moreBackground: Hand osteoarthritis (HOA) is a highly prevalent rheumatic disease that predominates in females and causes pain and loss of functional capacity. Obesity and metabolic syndrome have been previously suggested to associate with the severity of HOA, but clarity on these associations is yet to be achieved.Objective: Test the association between obesity and other components of the metabolic syndrome and disability in women with hand osteoarthritis (HOA).Design: Individuals from EpiReumaPt epidemiological community-based study (2011-2013) are representative of the Portuguese population. Women with diagnosis of primary HOA were included.Primary outcome: hand functional status, assessed by Cochin questionnaire.Secondary outcomes: hand pain, assessed by visual analogue scale and tender hand joint count (THJ).Explanatory variables: obesity, diabetes mellitus, arterial hypertension and hypercholesterolemia. Possible associations between obesity and the other components of metabolic syndrome with Cochin score, hand pain and THJ were tested in a multivariable linear regression model.Potential confounders considered: age, education level and countrywide distribution.Results: 473 women with primary HOA were included. Forty percent were overweight and 29% obese. Ninety-three (19.8%) participants had diabetes, 261 (55.8%) reported hypertension and 261 (55.9%) hypercholesterolemia. Mean Cochin score was 15.5 +/- 14.8, mean pain VAS was 4.7 +/- 2.6 and mean THJ 1.4 +/- 3. In the multivariable analysis, obesity (beta 4.6 CI 0.7;8.5) and diabetes (beta 4.0 CI 0.4;7.6) were found to significantly associate with HOA functional disability. In addition, diabetes, but not obesity, associated with hand pain. There was no association between obesity or diabetes with THJ.Conclusion: In a Portuguese female population with primary HOA, obesity and diabetes mellitus independently associated with a worse hand functional status. These data add to evidence suggesting a role of metabolic factors in the severity of HOA. Show less

Show moreObjetive: The aim of this study was to investigate whether peripheral arthritis together with disease activity independently contribute to functional impairment over time in patients with axSpA and to evaluate if there are contextual factors modifying this relationship.Material and methods: Patients with axial spondyloarthritis from the ESPAXIA cohort were followed-up annually over a mean of 3.7 years. Physical function was assessed by the self-reported questionnaire BASFI, disease activity by ASDAS and peripheral arthritis was also recorded. Generalized estimating equations (GEE) were used to investigate longitudinal association between peripheral arthritis, ASDAS and BASFI as the outcome. Autoregressive models (adjusted for BASFI 1 year earlier) were run to allow for a truly longitudinal interpretation. Interactions between each of ASDAS and peripheral arthritis with contextual factors (age, gender, educational level, smoking, job type) were tested.Results: 185 patients (77 % male, mean (SD) age 42 (13) years old and mean disease duration (SD) of 9.4 (9.6) years) were included. ASDAS and peripheral arthritis independently contributed to explaning BASFI over time. Contextual factors did not modify either of the relationships. A true longitudinal relation was proven with the autoregressive GEE model, showing that, adjusted for age, gender, spinal mobility and use of NSAIDs, an increase of one ASDAS unit led to a BASFI 0.48 units higher (ss 0.48 [95%CI 0.39, 0.57]), and the presence of peripheral arthritis, to a BASFI 0.44 units higher (ss 0.44 [95%CI 0.08, 0.8]). Conclusion: Peripheral arthritis and higher disease activity independently lead to more functional impairment in axSpA over time. Contextual factors do not modify these relationships.(c) 2021 Elsevier Inc. All rights reserved. Show less

Show moreObjective: Towards developing an instrument to measure knee and hip osteoarthritis (KHOA) flare, the Out-come Measures in Rheumatology (OMERACT) Flares in OA Working Group first sought to identify and define relevant domains of flare in KHOA.Methods: Guided by OMERACT Filter 2.1, candidate domains were identified from data generated in inter-views, in English or French, with persons with KHOA and health professionals (HPs) who treat OA. The first and second rounds of an online Delphi process with patients and HPs, including researchers, selected rele-vant domains. The third round provided agreement on the selected domains and their definitions. At the vir-tual OMERACT 2020 workshop, the proposed domains and their definitions were discussed in facilitated breakout groups with patients and HPs. Participants then voted, with consensus set at >= 70%.Results: Qualitative interviews characterizing OA flare were completed with 29 persons with KHOA and 16 HPs. Content was analyzed and grouped into nine clusters. These candidate domains were included in two Delphi rounds, completed by 91 patients and 165 HPs then 50 patients and 116 HPs, per round, respectively. This resulted in selecting five relevant domains. A final Delphi round, completed by 38 patients and 89 HPs, provided agreement on these domains and their definitions. The OMERACT virtual vote included 27 patients and 106 HPs. The domains and their definitions were endorsed with >= 98% agreement. Domains include: Pain, Swelling, Stiffness, Psychological aspects, and Impact of symptoms, all defined "during flare".Conclusion: Using OMERACT methodology, we have developed five domains of KHOA flare that were highly endorsed by patients and HPs.

Show moreObjective: The human resting myofascial tone maintains the body tone in a neutral posture, the assessment of this and other muscle physical properties (MPP) is relevant, since, it is altered in many pathological states.Patients and methods: Seventeen healthy subjects (8 males), between 18-50 years old, were assessed. The MPP of lower lumbar muscles was evaluated on right and left sides during prone resting position using two devices; myotonometry (stiffness, elasticity and tone) and ultrasound-based shear-wave elastography (SWE) (shear modulus). MTM measurements were performed at two anatomic points (ANp), selected by an experienced reader and at an adjacent ultra-sound determined point (USp). Myotonometry measurements of the erector spinae and SWE measurements of multifidus muscles at the L3-4 level were compared between genders and sides. The intra-reader reliability (IRR) for each device and correlations between techniques were analysed. MTM measurements performed at ANp and USp were compared. The intraclass correlation coefficient (ICC) was assessed for both devices. Correlations between stiffness (myotonometry) and shear modulus (SWE) at the respective muscle depths were assessed with Spearman correlation.Results: Males had greater stiffness and tone than females, particularly on the dominant side. MPP assessed by myotonometry were not different between ANp and USp. Good/Excellent 1RR was documented for measurements by MTM (ICC >= 0.90) and SWE (ICC >= 0.85). No correlation in myotonometry stiffness and SWE shear modulus was found. For myotonometry assessments, the addition of ultrasonography was not different from anatomic localizations. No correlation of measurements was found between devices assessing respective L3-4 level muscles.Conclusions: Gender and side differences must be considered when assessing MPP in axial muscles. For MTM assessments, the addition of ultrasonography was not different to anatomic references. No correlation was found between devices. Show less

Show moreObjectives: COVID-19 is an ongoing global pandemic. There is an urgent need for identification and understanding of clinical and laboratory parameters related to progression towards a severe and fatal form of this illness, often preceded by a so-called cytokine-storm syndrome (CSS). Therefore, we explored the hemocytometric characteristics of COVID-19 patients in relation to the deteriorating clinical condition CSS, using the Sysmex XN-10 hematology analyzer.Methods: From March 1st till May 16th, 2020, all patients admitted to our hospital with respiratory complaints and suspected for COVID-19 were included (n=1,140 of whom n=533 COVID-19 positive). The hemocytometric parameters of immunocompetent cells in peripheral blood (neutrophils [NE], lymphocytes [LY] and monocytes [MO]) obtained upon admission to the emergency department (ED) of COVID-19 positive patients were compared with those of the COVID-19 negative ones. Moreover, patients with CSS (n=169) were compared with COVID-19 positive patients without CSS, as well as with COVID-19 negative ones.Results: In addition to a significant reduction in leukocytes, thrombocytes and absolute neutrophils, it appeared that lymphocytes-forward scatter (LY-FSC), and reactive lymphocytes (RE-LYMPHO)/leukocytes were higher in COVID-19-positive than negative patients. At the moment of presentation, COVID-19 positive patients with CSS had different neutrophils- side fluorescence (NE-SFL), neutrophils-forward scatter (NE-FSC), LY-FSC, RE-LYMPHO/lymphocytes, antibody-synthesizing (AS)-LYMPHOs, high fluorescence lymphocytes (HFLC), MO-SSC, MO-SFL, and Reactive (RE)-MONOs. Finally, absolute eosinophils, basophils, lymphocytes, monocytes and MO-FSC were lower in patients with CSS.Conclusions: Hemocytometric parameters indicative of changes in immunocompetent peripheral blood cells and measured at admission to the ED were associated with COVID-19 with and without CSS.

Show moreObjective As part of European League against Rheumatism (EULAR)/European Musculoskeletal Conditions Surveillance and Information Network, 20 user-focused standards of care (SoCs) for rheumatoid arthritis (RA) addressing 16 domains of care were developed. This study aimed to explore gaps in implementation of these SoCs across Europe.Methods Two cross-sectional surveys on the importance, level of and barriers (patients only) to implementation of each SoC (0-10, 10 highest) were designed to be conducted among patients and rheumatologists in 50 European countries. Care gaps were calculated as the difference between the actual and maximum possible score for implementation (ie, 10) multiplied by the care importance score, resulting in care gaps (0-100, maximal gap). Factors associated with the problematic care gaps (ie, gap >= 30 and importance >= 6 and implementation<6) and strong barriers (>= 6) were further analysed in multilevel logistic regression models.Results Overall, 26 and 31 countries provided data from 1873 patients and 1131 rheumatologists, respectively. 19 out of 20 SoCs were problematic from the perspectives of more than 20% of patients, while this was true for only 10 SoCs for rheumatologists. Rheumatologists in countries with lower gross domestic product and non-European Union countries were more likely to report problematic gaps in 15 of 20 SoCs, while virtually no differences were observed among patients. Lack of relevance of some SoCs (71%) and limited time of professionals (66%) were the most frequent implementation barriers identified by patients.Conclusions Many problematic gaps were reported across several essential aspects of RA care. More efforts need to be devoted to implementation of EULAR SoCs. Show less

Show moreObjective: The Assessments of SpondyloArthritis international Society Health Index (ASAS HI), estimates the impact of Spondyloarthritis (SpA) on global functioning and health. This article assesses the construct validity, reliability and responsiveness of the Portuguese version of the ASAS HI.Patients And Methods: Patients fulfilling ASAS classification criteria for axial (axSpA) or peripheral SpA (pSpA) were included. Construct validity was assessed through Spearman's correlation analysis with other health outcomes. Discriminant validity was tested comparing the ASAS HI across disease activity and functional states using the Kruskal-Wallis test. Internal consistency was assessed by Cronbach's alpha, and test-retest reliability by intraclass correlation coefficients (ICC). Responsiveness was evaluated by the standardized response mean (SRM) in patients with active disease who required therapy escalation.Results: Among the 91 patients included, 67% were male, mean (SD) age 47.2 (12.9) years, 63 patients with axSpA and 28 patients with pSpA. The hypothesis defined a priori to test construct validity were confirmed. The ASAS HI showed ability to discriminate between patients with different disease activity and functional states (p<0.001). Internal consistency (Cronbach's alpha: 0.88) and test-retest reliability [ICC=0.76 (95%CI 0.09-0.91)] were good. Responsiveness was moderate (SRM=-0.53). The smallest detectable change was 3.0.Conclusions: The Portuguese version of the ASAS HI is a comprehensible questionnaire that is valid, reliable and responsive. It can be used to assess the impact of SpA and its treatment on functioning and health, in clinical practice and for research purposes. Show less
