RESUMEN
OBJECTIVE: To summarise current data regarding the use of imaging in crystal-induced arthropathies (CiAs) informing a European Alliance of Associations for Rheumatology task force. METHODS: We performed four systematic searches in Embase, Medline and Central on imaging for diagnosis, monitoring, prediction of disease severity/treatment response, guiding procedures and patient education in gout, calcium pyrophosphate dihydrate deposition (CPPD) and basic calcium phosphate deposition (BCPD). Records were screened, manuscripts reviewed and data of the included studies extracted. The risk of bias was assessed by validated instruments. RESULTS: For gout, 88 studies were included. Diagnostic studies reported good to excellent sensitivity and specificity of dual-energy CT (DECT) and ultrasound (US), high specificity and lower sensitivity for conventional radiographs (CR) and CT. Longitudinal studies demonstrated sensitivity to change with regard to crystal deposition by US and DECT and inflammation by US and structural progression by CR and CT. For CPPD, 50 studies were included. Diagnostic studies on CR and US showed high specificity and variable sensitivity. There was a single study on monitoring, while nine assessed the prediction in CPPD. For BCPD, 56 studies were included. There were two diagnostic studies, while monitoring by CR and US was assessed in 43 studies, showing a reduction in crystal deposition. A total of 12 studies with inconsistent results assessed the prediction of treatment response. The search on patient education retrieved two studies, suggesting a potential role of DECT. CONCLUSION: This SLR confirmed a relevant and increasing role of imaging in the field of CiAs.

OBJECTIVE: To formulate evidence-based recommendations and overarching principles on the use of imaging in the clinical management of crystal-induced arthropathies (CiAs). METHODS: An international task force of 25 rheumatologists, radiologists, methodologists, healthcare professionals and patient research partners from 11 countries was formed according to the EULAR standard operating procedures. Fourteen key questions on the role of imaging in the most common forms of CiA were generated. The CiA assessed included gout, calcium pyrophosphate deposition disease and basic calcium phosphate deposition disease. Imaging modalities included conventional radiography, ultrasound, CT and MRI. Experts applied research evidence obtained from four systematic literature reviews using MEDLINE, EMBASE and CENTRAL. Task force members provided level of agreement (LoA) anonymously by using a Numerical Rating Scale from 0 to 10. RESULTS: Five overarching principles and 10 recommendations were developed encompassing the role of imaging in various aspects of patient management: making a diagnosis of CiA, monitoring inflammation and damage, predicting outcome, response to treatment, guided interventions and patient education. Overall, the LoA for the recommendations was high (8.46-9.92). CONCLUSIONS: These are the first recommendations that encompass the major forms of CiA and guide the use of common imaging modalities in this disease group in clinical practice.

New evidence from 2023 has slightly shifted some perspectives on rheumatoid arthritis (RA) management. Glucocorticoids have reaffirmed their role as bridging therapy, while novel studies on JAK inhibitors have examined efficacy, mechanism of action, and their potential in high-risk populations, bolstering our understanding with real-world data.Additionally, among treatment strategies, achieving low disease activity has emerged as comparable to achieving remission in the long term, and new insights have been gained regarding tapering both biological and conventional synthetic DMARDs. Furthermore, novel approaches have been proposed for managing difficult-to-treat RA and pre-RA. In this paper, the reviewers aim to present the most relevant studies published during the last year in the field of RA management.

OBJECTIVES: Rheumatoid arthritis (RA) patients are at high risk of cardiovascular (CV) events. The aim of this position paper is to provide Italian rheumatologists with an easy, feasible and time-saving CV risk assessment in their daily clinical practice. METHODS: A narrative review of the literature and an assessment of the methodological strength underlying the current evidence on CV risk assessment in patients with RA were performed. The evidence-based results were shared among the members of the steering committee of the CORDIS study group of the Italian Society of Rheumatology. Subsequently, a unanimously agreed-upon algorithm was discussed and finally approved by the experts. RESULTS: RA patients should have their CV profile monitored using the Italian 'Progetto Cuore' chart, according to the current EULAR recommendations for CV risk management, at least every 5 years. In the presence of high disease activity, or a multi-drug failure condition, when prolonged treatment with glucocorticoids and/or NSAIDs is required, or if hypertension, dyslipidaemia, or diabetes mellitus are concomitant, a more stringent CV risk assessment should be considered. When moderate CV risk is documented, patients should undergo intima-media thickening measurement. The condition of high CV risk requires a cardiological evaluation. CONCLUSIONS: This position paper provides five Italian recommendations for CV risk assessment in RA patients. A general and uniform approach to CV risk profiling may be useful to identify those patients who should undertake intensive preventive strategies to improve their CV outcomes.

New evidence from 2022 slightly changed some perspectives for rheumatoid arthritis (RA) management. Real-world data on the efficacy and safety of disease-modifying anti-rheumatic drugs strengthened the importance of tailoring treatment decisions based on patient characteristics. Moreover, the research of response biomarkers to therapy underlined the need for precision medicine and remote care applications showed an innovative outlook that supports a patient-centred approach. New developments in vaccinations led to the release of updated guidelines and to a consistent improvement in the prevention of vaccine-preventable infections. New literature data also reconsidered drug management in RA-associated interstitial lung disease and pregnancy. In this paper, the reviewers aim to present the most relevant studies published during the last year in the field of RA management.

OBJECTIVE: To investigate the associations between the Patient Global Assessment (PGA) and measures of disease activity in patients with rheumatoid arthritis (RA) in relation to disease duration and autoantibody status. METHODS: 1412 patients from three independent cohorts were studied: a prospective cohort of 810 patients with early RA followed up for 24 months; a cross-sectional cohort of 210 patients with established RA in low disease activity; a cross-sectional cohort of 401 patients with established RA in moderate-to-high disease activity. Correlations of the PGA were analysed by Pearson's coefficients and multivariable linear regression at baseline and at months 6, 12 and 24 in the overall populations and after stratification for autoantibody subgroup and remission status (Boolean remission, PGA near remission and non-remission). RESULTS: In patients with early RA in non-remission, swollen joints correlated independently with the PGA; the correlation became progressively weaker but persisted at all time points in autoantibody-positive patients (adjusted r=0.30-0.12) but lost significance after month 12 in autoantibody-negative patients. Swollen joints independently correlated with the PGA also in near remission until month 12 (adjusted r=0.18-0.16) in autoantibody-positive patients. No independent correlations of inflammatory variables were instead found in patients with established RA irrespective of disease activity and autoantibody status. CONCLUSIONS: In the early phases of RA, particularly in autoantibody-positive patients, inflammatory variables directly correlate with the PGA across different disease activity states. The optimal cut-off values of the PGA capable of identifying absence of disease should be better explored in relation to disease duration and autoantibody status.

OBJECTIVES: This study aimed to determine the prevalence of ultrasound-detected tendon abnormalities in healthy subjects (HS) across the age range. METHODS: Adult HS (age 18-80 years) were recruited in 23 international Outcome Measures in Rheumatology ultrasound centres and were clinically assessed to exclude inflammatory diseases or overt osteoarthritis before undergoing a bilateral ultrasound examination of digit flexors (DFs) 1-5 and extensor carpi ulnaris (ECU) tendons to detect the presence of tenosynovial hypertrophy (TSH), tenosynovial power Doppler (TPD) and tenosynovial effusion (TEF), usually considered ultrasound signs of inflammatory diseases. A comparison cohort of patients with rheumatoid arthritis (RA) was taken from the Birmingham Early Arthritis early arthritis inception cohort. RESULTS: 939 HS and 144 patients with RA were included. The majority of HS (85%) had grade 0 for TSH, TPD and TEF in all DF and ECU tendons examined. There was a statistically significant difference in the proportion of TSH and TPD involvement between HS and subjects with RA (HS vs RA p<0.001). In HS, there was no difference in the presence of ultrasound abnormalities between age groups. CONCLUSIONS: Ultrasound-detected TSH and TPD abnormalities are rare in HS and can be regarded as markers of active inflammatory disease, especially in newly presenting RA.

OBJECTIVE: We aimed to systematically review the literature to retrieve evidence on the diagnostic and prognostic value of musculoskeletal ultrasound for a treat to target (T2T) approach in RA. METHODS: Eight research questions were developed addressing the role of ultrasound (including different ultrasound scores and elementary lesions) for diagnosis, monitoring and prognosis of RA. PubMed and EMBASE were searched (2005-2020). Articles on RA and reporting data on musculoskeletal ultrasound were included and extracted according to the underlying questions, and risk of bias assessed according to the study design. RESULTS: Out of 4632 records, 60 articles were included. Due to clinical heterogeneity, meta-analysis was not possible. Ultrasound better predicted disease relapses with respect to clinical examination in patients in remission, while both methods performed similarly in predicting response to therapy, achievement of remission and radiographic progression. Ultrasound was superior to clinical examination in diagnosing joint involvement using another imaging modality, such as magnetic resonance imaging, as reference. Limited ultrasound scores performed like more extensive evaluations for the detection of joint inflammation and for outcome prediction. Higher ultrasound scores of synovitis were linked to poor outcomes at all disease stages, but a specific cut-off distinguishing between low- and high-risk groups did not emerge. CONCLUSIONS: These data confirm the pivotal role of ultrasound when evaluating synovial inflammation and when identifying RA patients at higher risk of relapse. Further research is needed to better define the role of ultrasound in a T2T management strategy in moderately-to-highly active RA.

New evidence for the treatment of rheumatoid arthritis (RA) has emerged during the last year. Specifically, updated guidelines on pharmacological and non-pharmacological management of RA have emphasised the necessity of global patient's care, and have shifted the role of some older drugs, such as glucocorticoids and methotrexate. In addition, the long-term safety of Janus kinase inhibitors was investigated and reinforced. With respect to the coronavirus-19 pandemic, reassuring data on the efficacy and safety of vaccinations in the RA population were acquired, as well as on the potential role of telemedicine in RA management. Machine learning prediction models and biomarkers development have emerged as promising innovations in the area of precision/personalised medicine, appearing to encourage future expansion.In this narrative review, the authors aim to give their specific point of view on the most relevant and potentially impacting novelties published during 2021 and early 2022 in the context of RA management.

OBJECTIVES: Anti-synthetase syndrome (ASSD) is a heterogeneous autoimmune disease characterised by multi-system involvement with a wide variety of manifestations. Validated classification criteria are necessary to improve recognition and prevent misclassification, especially given the lack of reliable and standardised autoantibody testing. We systematically reviewed the literature to analyse proposed ASSD criteria, characteristics, and diagnostic performance. METHODS: We searched PubMed and Embase databases (01/01/1984 to 06/11/2018) and the ACR and EULAR meeting abstracts (2017-2018). Sensitivities, specificities, positive, negative likelihood ratios and risk of bias were calculated for ASSD criteria and key variables reported in the literature. We performed meta-analysis when appropriate. RESULTS: We retrieved 4,358 studies. We found 85 proposed ASSD criteria from a total of 82 studies. All but one study included anti-synthetase autoantibody (ARS) positivity in the ASSD criteria. Most studies required only one ASSD feature plus anti-ARS to define ASSD (n=64, 78%), whereas 16 studies required more than one ASSD variable plus anti-ARS. The only criteria not including anti-ARS positivity required 5 ASSD clinical features. We found limited data and wide variability in the diagnostic performance of each variable and definition proposed in the literature. Given these limitations we only meta-analysed the performance of individual muscle biopsy and clinical variables in diagnosing ASSD, which performed poorly. CONCLUSIONS: The current ASSD criteria include a variety of serological, clinical, and histological features with wide variability amongst proposed definitions and the performance of these definitions has not been tested. This systematic literature review suggests the need for additional data and consensus-driven classification criteria for ASSD.

OBJECTIVE: The aim of the study is to assess the performance of the DACTOS (DACtylitis glObal Sonographic) score in a PsA dactylitis clinical setting. In particular, we evaluated the ability of DACTOS to identify the affected fingers, its sensitivity to change after treatment, the correlations between DACTOS and clinical parameters, and the capacity of the score to identify the treatment responders. METHODS: Forty-six consecutive patients with symptomatic PsA hand dactylitis were enrolled. A total of seventy-three dactylitic digits were evaluated clinically and sonographically before and after treatment in this observational and prospective study. Clinical assessment included the Leeds Dactylitis Index-basic (LDI-b) score and visual analogue scales for pain (VAS-p) and functional impairment (VAS-FI). Sonographic lesions were investigated using high-frequency ultrasound with grey scale and power Doppler features according to the DACTOS score. Correlations between the DACTOS score and the clinical parameters were assessed at baseline, 1 month (T1) and 3 months (T3). RESULTS: We observed significant improvements in all of the assessed clinical parameters and the DACTOS scores after dactylitis treatment. There was a statistically significant correlation between the variation of all clinical parameters (VAS-p, VAS-FI and LDI-b) and the DACTOS score at T1 and T3 evaluations. We found statistically significant differences in the DACTOS score between clinical responder and non-responder groups (P < 0.001) and between clinical remission and non-remission groups (P < 0.001). CONCLUSION: The DACTOS score performs well in real-life clinical settings in terms of sensitivity to change and correlations with clinical features in PsA dactylitis.

In the setting of rheumatology, the assessment of the involvement of joints and peri-articular structures was the first application of ultrasonography in the management of rheumatic diseases. In this field, the main novelties are related to the development of new technical tools to help overcome some of the limitations of conventional ultrasonographic assessment. In the meantime, there has been a growing interest in the application of ultrasound to extra-articular sites, relying on the definition of new indications. The present review aims to provide a critical analysis of the technical developments and new fields of application of ultrasonography in rheumatology.

Management of rheumatoid arthritis (RA) has evolved over the years as a result of better understanding of the role of different therapeutic strategies, as well as following an increasing availability of new disease-modifying antirheumatic drugs. However, the role of patients in sharing decisions, as well as the rules informing precision medicine or the principles to follow in case of specific comorbidities or extra-articular manifestations are still areas for improvement. Moreover, in 2020, the novel Coronavirus disease-19 outbreak has completely changed many attitudes in terms of assessment and treatment paradigms in most clinical diseases, including RA. In this narrative review, the authors report their specific point of view on the management of RA, based on a critical revision of literature published in 2020, focusing on relevant novelties and future research directions.

OBJECTIVES: Dactylitis is one of the most typical features of psoriatic arthritis (PsA), with a high lifetime prevalence and inclusion in PsA clinical indices. Musculoskeletal ultrasonography (Msk-US) can readily detect inflammatory involvement of finger anatomical structures particular to dactylitis and monitor therapeutic effects. In this study, we aim to identify the characteristic lesions in PsA dactylitis of the hands, assess the reliability of Msk-US in scoring those lesions and develop a DACTylitis glObal Sonographic (DACTOS) score. METHODS: After a systematic literature review on the use of Msk-US in PsA dactylitis, 12 rheumatologists participated in a three-round Delphi procedure and consensus meeting to agree on the sonographic elementary lesions characterising dactylitis and on the composition of a global sonographic score. Then, a web-based and a patient-based intra-rater and inter-rater reliability exercise was performed to assess those lesions included in the score. RESULTS: DACTOS score was obtained by summing the scores of each lesion selected in the Delphi survey: subcutaneous soft tissue oedema, flexor tenosynovitis, peritendon extensor inflammation and synovitis. The DACTOS score ranges from 0 to 25. In the reliability exercises, we obtained moderate-to-excellent agreement for the sonographic lesions included in the score. CONCLUSIONS: The novel DACTOS score is a reliable measure to interpret the multiple characteristic sonographic features of dactylitis. The DACTOS score provides a useful global analysis of dactylitis of the hand and can represent a support to clinical diagnosis as well as a useful tool for the management and research in patients with PsA with dactylitis.

Rheumatoid arthritis (RA) management is driven by evidence, and new 2019 EULAR recommendations help in refining the relevant place of different disease-modifying anti-rheumatic drugs (DMARDs) in treatment schedules. At present, new drugs are in phase of development, mainly Janus Kinase inhibitors (JAKis), however, specific treatment strategies seem to count more than individual DMARDs in terms of treatment responses, given the substantial lack of head-to-head comparisons between specific biological (b) and targeted synthetic (ts)DMARDs, and with the general perception of a similar efficacy profile across drugs. In this setting, when reliable biomarkers able to predict treatment responses are lacking, treatment decisions are mainly driven by specific clinical or individual factors, given the recognised role of comorbidities, treatment-specific side effects, patients' preferences, and costs on drug choice. In this narrative review, the authors give their specific point of view on the management of RA, based on a critical revision of the literature published in 2019, focusing on relevant novelties and future research directions.

OBJECTIVES: The aims of this study were to define the risk of serious bacterial infections in patients receiving specific biological disease-modifying anti-rheumatic drugs (bDMARDs) and evaluating the effect of concomitant synthetic DMARDs (sDMARDs) in a large population-based sample of rheumatoid arthritis (RA) deriving from an administrative health database. METHODS: Data were extracted from health databases of Lombardy Region, Italy (2004-2013), as a part of the RECord-linkage On Rheumatic Diseases (RECORD) study. Patients with RA treated with approved bDMARDs were included. Hospitalisations for bacterial infections were evaluated by hospital discharge forms. The association between drug exposure and infections was assessed by survival models, with time-dependent covariates. Results are presented as hazard ratios (HR) and 95%CI, crude and adjusted for pre-specified confounders (sex, age, disease duration, Charlson Comorbidity Index, previous biologics, previous infections, use of methotrexate, leflunomide, corticosteroids, non-steroidal anti-inflammatory drugs). RESULTS: 4,656 RA patients with at least one bDMARD prescription were included, for a total of 7,601 biological courses; 3,603 (77.4%) women with a mean (SD) age of 55.8 (12.7) years. Crude incidence rate of hospitalised infection ranged from 0.14 to 2.95 per 1000 person-years. After multivariable adjustment, abatacept users (HR 0.29, 95%CI 0.10-0.82) had significantly lower risk of infections compared to etanercept. Concurrent treatment with methotrexate (0.72, 0.52-0.99) reduced the overall risk of infection while glucocorticoids increased it (1.09 per mg/day, 1.06-1.11). CONCLUSIONS: In RA patients treated with bDMARDs, abatacept was associated with the lowest risk of infections; overall risk was mitigated by concomitant methotrexate and increased by glucocorticoids in a dose-dependent manner.

OBJECTIVES: We aimed to evaluate the correlation between serum calprotectin and clinical and ultrasonographic (US) variables in early-onset psoriatic arthritis (PsA) and controls with rheumatoid arthritis (RA). METHODS: In a retrospective cross-sectional study, including PsA and matched RA patients, 44 joint counts (TJC, SJC), calprotectin, ESR and CRP were measured. US of wrists and MCPs 1-5 was performed, with grey-scale (GS) and power Doppler (PD) scored 0-3 at each site, summed in a total score. The correlation between calprotectin, clinical and US variables was evaluated by Spearman's coefficient, the predictivity by calprotectin of US by regression. Secondary analyses separating polyarticular PsA and using different US definitions (GS>1, PD>1) were performed. RESULTS: 78 PsA and 78 RA were included (PsA male 32%; mean age 51.7 (13.5)). Calprotectin did not significantly differ in PsA and RA. In PsA, calprotectin correlated with GS score (ρ=0.340, p=0.008), PD score (ρ=0.292, p=0.023) and the presence of PD (ρ=0.263, p=0.042); in RA there were no significant correlations. In polyarticular PsA, a significant correlation between calprotectin and GS (ρ=0.369, p=0.019) and PD scores (ρ=0.363, p=0.021) was confirmed. In both PsA and RA, calprotectin and CRP significantly correlated, while SJC and TJC did not. In the regression analysis, calprotectin did not predict US variables in PsA. Similar results were achieved in RA. CONCLUSIONS: In early PsA, serum calprotectin correlates with US measures of disease activity. Our results provide preliminary evidence for the application of this biomarker in early PsA.

OBJECTIVE: To define the role of ultrasound (US) for the assessment of patients with rheumatoid arthritis (RA) in clinical remission, including joint and tendon evaluation. METHODS: A multicentre longitudinal study has been promoted by the US Study Group of the Italian Society for Rheumatology. 25 Italian centres participated, enrolling consecutive patients with RA in clinical remission. All patients underwent complete clinical assessment (demographic data, disease characteristics, laboratory exams, clinical assessment of 28 joints and patient/physician-reported outcomes) and Power Doppler (PD) US evaluation of wrist, metacarpalphalangeal joints, proximal interphalangeal joints and synovial tendons of the hands and wrists at enrolment, 6 and 12 months. The association between clinical and US variables with flare, disability and radiographic progression was evaluated by univariable and adjusted logistic regression models. RESULTS: 361 patients were enrolled, the mean age was 56.20 (±13.31) years and 261 were women, with a mean disease duration of 9.75 (±8.07) years. In the 12 months follow-up, 98/326 (30.1%) patients presented a disease flare. The concurrent presence of PD positive tenosynovitis and joint synovitis predicted disease flare, with an OR (95% CI) of 2.75 (1.45 to 5.20) in crude analyses and 2.09 (1.06 to 4.13) in adjusted analyses. US variables did not predict the worsening of function or radiographic progression. US was able to predict flare at 12 months but not at 6 months. CONCLUSIONS: PD positivity in tendons and joints is an independent risk factor of flare in patients with RA in clinical remission. Musculoskeletal ultrasound evaluation is a valuable tool to monitor and help decision making in patients with RA in clinical remission.
