Objectives: This study aimed to evaluate the impact of different comorbidities on thereflecting its safety profile persistence of biological disease-modifying anti-rheumatic drugs (bDMARDs) in rheumatoid arthritis (RA), taking advantage of a retrospective analysis of administrative healthcare databases (AHDs). Method: A retrospective observational study was conducted on AHDs of the Lombardy region, Italy (2004–2013). Among RA patients treated with bDMARDs, drug survival was estimated using Cox proportional hazard models [hazard ratio (HR), 95% confidence interval (CI)], crude and adjusted for prespecified confounders (gender, age, disease duration, concomitant use of non-steroidal anti-inflammatory drugs, glucocorticoids, conventional DMARDs, specific bDMARDs), in first-line and subsequent lines of treatment. The role of comorbidities in administration of specific bDMARDs was analysed through multinomial logistic models. Results: The study included 4657 RA patients. In the first-line treatment strategy, the Charlson Comorbidity Index (CCI) (RA excluded) was significantly associated with an increased rate of bDMARD failure (CCI = 1: HR 1.28, 95% CI 1.13–1.46; CCI ≥ 2: HR 1.26, 95% CI 1.03–1.53). Among selected comorbidities, chronic obstructive pulmonary disease (HR 1.38, 95% CI 1.01–1.91), diabetes (HR 1.18, 95% CI 1.01–1.37), and previous-year bacterial infections (HR 1.18, 95% CI 1.07–1.30) were slightly associated with risk of bDMARD failure, while acute myocardial infarction (HR 1.30, 95% CI 0.97–1.75), mild liver disease (HR 1.21, 95% CI 0.91–1.60), and solid tumours (HR 1.19, 95% CI 0.93–1.53) were not. In the following treatment lines, neoplasms were associated with reduced risk of failure (HR 0.64, 95% CI 0.41–0.99). Multiple comorbidities were associated with first-line abatacept and rituximab administration. Conclusions: Comorbidities affect treatment decisions in RA and influence bDMARD failure, and should be considered when analysing the persistence of biological therapy. [ABSTRACT FROM AUTHOR]

A low-cost array of modular sensors for online monitoring of radioactive waste was developed at INFN-LNS. We implemented a new kind of gamma counter, based on Silicon PhotoMultipliers and scintillating fibers, that behaves like a cheap scintillating Geiger-Muller counter. It can be placed in shape of a fine grid around each single waste drum in a repository. Front-end electronics and an FPGA-based counting system were developed to handle the field data, also implementing data transmission, a graphical user interface and a data storage system. A test of four sensors in a real radwaste storage site was performed with promising results. Following the tests an agreement was signed between INFN and Sogin for the joint development and installation of a prototype DMNR (Detector Mesh for Nuclear Repository) system inside the Garigliano radwaste repository in Sessa Aurunca (CE, Italy). Such a development is currently under way, with the installation foreseen within 2014.

We developed a technique for thermal neutron detection not making use of 3He, also suitable for online real time monitoring of CASTOR spent fuel containers. As a neutron converter we used 6LiF, being the neutron capture cross section of 6Li very well known and with only an alpha and a triton in the exit channel. We can deposit thin layers of converter onto several different substrates, to be placed on top of solid state detectors or scintillators capable of efficiently detecting the decay products.

Objective: Anti-synthetase syndrome (ASSD) is a rare systemic autoimmune rheumatic disease (SARD) with significant heterogeneity and no shared classification criteria. We aimed to identify clinical and serological features associated with ASSD that may be suitable for inclusion in the data-driven classification criteria for ASSD., Methods: We utilized a large, international, multi-center "Classification Criteria for Anti-synthetase Syndrome" (CLASS) project database, which includes both ASSD patients and controls with mimicking conditions, namely SARDs and/or interstitial lung disease (ILD). The local diagnoses of ASSD and controls were confirmed by project team members. We employed univariable logistic regression and multivariable Ridge regression to evaluate clinical and serological features associated with an ASSD diagnosis in a randomly selected subset of the cohort., Results: Our analysis included 948 ASSD cases and 1077 controls. Joint, muscle, lung, skin, and cardiac involvement were more prevalent in ASSD than in controls. Specific variables associated with ASSD included arthritis, diffuse myalgia, muscle weakness, muscle enzyme elevation, ILD, mechanic's hands, secondary pulmonary hypertension due to ILD, Raynaud phenomenon, and unexplained fever. In terms of serological variables, Jo-1 and non-Jo-1 anti-synthetase autoantibodies, antinuclear antibodies with cytoplasmic pattern, and anti-Ro52 autoantibodies were associated with ASSD. In contrast, isolated arthralgia, dysphagia, electromyography/MRI/muscle biopsy findings suggestive of myopathy, inflammatory rashes, myocarditis, and pulmonary arterial hypertension did not differentiate between ASSD and controls or were inversely associated with ASSD., Conclusion: We identified key clinical and serological variables associated with ASSD, which will help clinicians and offer insights into the development of data-driven classification criteria for ASSD., (This article is protected by copyright.

Objectives: The purpose of this study was to evaluate the performance of a dermatologist-filled-in 7-item questionnaire (called HERACLES) as a screening tool for psoriatic arthritis (PsA) in patients with psoriasis., Methods: This study was performed in Italy in seven dermatology centres cooperating with rheumatology centres. Adults with psoriasis were consecutively recruited up to a calculated number of 750. They were invited to fill in the following questionnaires used for PsA screening: ToPAS, PASE, PEST, and EARP. The dermatologists, in addition to standard demographic and clinical data, scored each participant using a new 7-item questionnaire. All participants were later evaluated by the rheumatologists for a diagnosis of PsA. The performance of the various questionnaires was compared using receiver-operating-characteristic (ROC) area-under-the-curve (AUC) analysis., Results: Of the 759 enrolled psoriatic patients, 524 (280 males and 244 females) were suitable for data analysis. PsA was diagnosed in 73 (13.9%) participants. PsA and non-PsA patient characteristics were comparable, except for arthritis-related features which were often more prevalent in the PsA group. The ROC AUC of the HERACLES instrument was 0.775 (CI: 0.722-0.828), similar to that of the other questionnaires (ToPAS 0.757; PASE 0.730; PEST 0.741; and EARP 0.739). For the HERACLES instrument, a score value of 2 yielded a sensitivity of 92% and a specificity of 47%., Conclusions: In this study, a dermatologist-filled-in questionnaire proved to be not inferior to patient-administered PsA screening tools and to be feasible. It might be an alternative (or additional) tool to screen psoriatic patients for rheumatology referral.

Objectives: The management of neuropsychiatric systemic lupus erythematosus (NPSLE) poses considerable challenges due to limited clinical trials. Therapeutic decisions are customized based on suspected pathogenic mechanisms and symptoms severity. This study aimed to investigate therapeutic strategies and disease outcome for patients with NPSLE experiencing their first neuropsychiatric (NP) manifestation., Methods: This retrospective cohort study defined NP events according to the American College of Rheumatology case definition, categorizing them into three clusters: central/diffuse, central/focal and peripheral. Clinical judgment and a validated attribution algorithm were used for NP event attribution. Data included demographic variables, SLE disease activity index, cumulative organ damage, and NP manifestation treatments. The clinical outcome of all NP events was determined by a physician seven-point Likert scale. Predictors of clinical improvement/resolution were investigated in a multivariable logistic regression analysis., Results: The analysis included 350 events. Immunosuppressants and corticosteroids were more frequently initiated/escalated for SLE-attributed central diffuse or focal NP manifestations. At 12 months of follow-up, 64% of patients showed a clinical improvement in NP manifestations. Focal central events and SLE-attributed manifestations correlated with higher rates of clinical improvement. Patients with NP manifestations attributed to SLE according to clinical judgment and treated with immunosuppressants had a significantly higher probability of achieving clinical response (OR 2.55, 95%CI 1.06-6.41, P = 0.04). Age at diagnosis and focal central events emerged as additional response predictors., Conclusion: NP manifestations attributed to SLE by clinical judgment and treated with immunosuppressants demonstrated improved 12-month outcomes. This underscores the importance of accurate attribution and timely diagnosis of NPSLE., (© The Author(s) 2024. Published by Oxford University Press on behalf of the British Society for Rheumatology.

Objective: To develop the optimal US scanning protocol for the diagnosis of calcium pyrophosphate crystal deposition (CPPD) disease., Methods: In this cross-sectional study, consecutive patients with a crystal-proven diagnosis of CPPD disease, and age-, sex-matched disease controls with a negative synovial fluid analysis were prospectively enrolled in two Italian Institutions. Four rheumatologists, blinded to patients' clinical details, performed US examinations using a standardized scanning protocol including 20 joints (shoulders, elbows, wrists, metacarpophalangeal joints from second to fifth fingers, hips, knees, ankles). CPPD was identified as presence/absence, according to the OMERACT definitions. Reduced US scanning protocols were developed by selecting the most informative joints to be imaged by US using the LASSO technique. Patients were randomly divided into training and validation sets. Their diagnostic accuracy was tested comparing the area under the receiver operating characteristic curves., Results: The number of participants enrolled was 204: 102 with CPPD disease and 102 disease controls [age, mean (s.d.): 71.3 (12.0) vs 71.1 (13.5) years; female: 62.8% vs 57.8%]. The median number of joints with US evidence of CPPD was 5 [interquartile range (IQR): 4-7] and 0 (IQR: 0-1) in patients with CPPD disease and controls, respectively (P < 0.01). The detection of CPPD in ≥2 joints using a reduced scanning protocol (bilateral assessment of knees, wrists and hips) showed a sensitivity of 96.7% (95% CI: 82.8, 99.9) and a specificity of 100 (95% CI: 88.8, 100.0) for the diagnosis of CPPD disease and had good feasibility [mean (s.d.): 12.5 (5.3) min]., Conclusion: Bilateral US assessment of knees, wrists and hips had excellent accuracy and good feasibility for the diagnosis of CPPD disease., (© The Author(s) 2023.

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: To investigate pregnancy outcomes in women with autoimmune rheumatic diseases (ARD) in the Italian prospective cohort study P-RHEUM.it., Methods: Pregnant women with different ARD were enrolled for up to 20 gestational weeks in 29 Rheumatology Centres for 5 years (2018-2023). Maternal and infant information were collected in a web-based database., Results: We analysed 866 pregnancies in 851 patients (systemic lupus erythematosus was the most represented disease, 19.6%). Maternal disease flares were observed in 135 (15.6%) pregnancies. 53 (6.1%) pregnancies were induced by assisted reproduction techniques, 61 (7%) ended in miscarriage and 11 (1.3%) underwent elective termination. Obstetrical complications occurred in 261 (30.1%) pregnancies, including 2.3% pre-eclampsia. Two cases of congenital heart block were observed out of 157 pregnancies (1.3%) with anti-Ro/SSA. Regarding treatments, 244 (28.2%) pregnancies were treated with glucocorticoids, 388 (44.8%) with hydroxychloroquine, 85 (9.8%) with conventional synthetic disease-modifying anti-rheumatic drugs and 122 (14.1%) with biological disease-modifying anti-rheumatic drugs. Live births were 794 (91.7%), mostly at term (84.9%); four perinatal deaths (0.5%) occurred. Among 790 newborns, 31 (3.9%) were small-for-gestational-age and 169 (21.4%) had perinatal complications. Exclusive maternal breast feeding was received by 404 (46.7%) neonates. The Edinburgh Postnatal Depression Scale was compiled by 414 women (52.4%); 89 (21.5%) scored positive for emotional distress., Conclusions: Multiple factors including preconception counselling and treat-to-target with pregnancy-compatible medications may have contributed to mitigate disease-related risk factors, yielding limited disease flares, good pregnancy outcomes and frequency of complications which were similar to the Italian general obstetric population. Disease-specific issues need to be further addressed to plan preventative measures., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Objective: This post-hoc analysis was carried out on data acquired in the longitudinal Sonographic Tenosynovitis/arthritis Assessment in Rheumatoid Arthritis Patients in Remission (STARTER) study. Its primary aim was to determine the predictive clinical and MSUS features factors for disease flare in RA patients in clinical remission, whilst its secondary aim was to evaluate the probability of disease flare based on clinical and MSUS features., Methods: The analysis included a total of 389 RA patients in DAS28-defined remission. All patients underwent a MSUS examination according to OMERACT guidelines. Logistic regression and results presented as OR and 95%CI were used for the evaluation of the association between selected variables and disease flare. Significant clinical and MSUS features were incorporated into a risk table to predict disease flare within 12 months in RA remission patients., Results: Within 12 months, 137(35%) RA patients experienced a disease flare. RA patients who experienced a flare disease differed from persistent remission for ACPA positivity (75.9%vs62.3%; p= 0.007), percentage of sustained clinical remission at baseline (44.1%vs68.5%; p= 0.001) and synovium PD signal presence (58.4%vs33.3%; p< 0.001). Based on these results, the three features were considered in a predictive model of disease flare with adjOR 3.064(95%CI 1.728-5.432). Finally, a risk table was constructed including the three significant predictive factors of disease flare within 12 months from the enrolment., Conclusion: An adaptive flare prediction model tool, based on data available in outpatient setting, were developed as a multiparametric risk table. If confirmed by the external validation, this tool might support the definition of therapeutic strategies in RA patients in DAS28-defined remission status., (© The Author(s) 2024.

Objectives: The CLASS (Classification Criteria of Anti-Synthetase Syndrome) project is a large international multicentre study that aims to create the first data-driven anti-synthetase syndrome (ASSD) classification criteria. Identifying anti-aminoacyl tRNA synthetase antibodies (anti-ARS) is crucial for diagnosis, and several commercial immunoassays are now available for this purpose. However, using these assays risks yielding false-positive or false-negative results, potentially leading to misdiagnosis. The established reference standard for detecting anti-ARS is immunoprecipitation (IP), typically employed in research rather than routine autoantibody testing. We gathered samples from participating centers and results from local anti-ARS testing. As an "ad-interim" study within the CLASS project, we aimed to assess how local immunoassays perform in real-world settings compared to our central definition of anti-ARS positivity., Methods: We collected 787 serum samples from participating centres for the CLASS project and their local anti-ARS test results. These samples underwent initial central testing using RNA-IP. Following this, the specificity of ARS was reconfirmed centrally through ELISA, line-blot assay (LIA), and, in cases of conflicting results, protein-IP. The sensitivity, specificity, positive likelihood ratio and positive and negative predictive values were evaluated. We also calculated the inter-rater agreement between central and local results using a weighted κ co-efficient., Results: Our analysis demonstrates that local, real-world detection of anti-Jo1 is reliable with high sensitivity and specificity with a very good level of agreement with our central definition of anti-Jo1 antibody positivity. However, the agreement between local immunoassay and central determination of anti-non-Jo1 antibodies varied, especially among results obtained using local LIA, ELISA and "other" methods., Conclusions: Our study evaluates the performance of real-world identification of anti-synthetase antibodies in a large cohort of multi-national patients with ASSD and controls. Our analysis reinforces the reliability of real-world anti-Jo1 detection methods. In contrast, challenges persist for anti-non-Jo1 identification, particularly anti-PL7 and rarer antibodies such as anti-OJ/KS. Clinicians should exercise caution when interpreting anti-synthetase antibodies, especially when commercial immunoassays test positive for non-anti-Jo1 antibodies.

Objective: Approximately one third of individuals worldwide have not received a COVID-19 vaccine. Although studies have investigated risk factors linked to severe COVID-19 among unvaccinated people with rheumatic diseases (RDs), we know less about whether these factors changed as the pandemic progressed. We aimed to identify risk factors associated with severe COVID-19 in unvaccinated individuals in different pandemic epochs corresponding to major variants of concern., Methods: Patients with RDs and COVID-19 were entered into the COVID-19 Global Rheumatology Alliance Registry between March 2020 and June 2022. An ordinal logistic regression model (not hospitalized, hospitalized, and death) was used with date of COVID-19 diagnosis, age, sex, race and/or ethnicity, comorbidities, RD activity, medications, and the human development index (HDI) as covariates. The main analysis included all unvaccinated patients across COVID-19 pandemic epochs; subanalyses stratified patients according to RD types., Results: Among 19,256 unvaccinated people with RDs and COVID-19, those who were older, male, had more comorbidities, used glucocorticoids, had higher disease activity, or lived in lower HDI regions had worse outcomes across epochs. For those with rheumatoid arthritis, sulfasalazine and B-cell-depleting therapy were associated with worse outcomes, and tumor necrosis factor inhibitors were associated with improved outcomes. In those with connective tissue disease or vasculitis, B-cell-depleting therapy was associated with worse outcomes., Conclusion: Risk factors for severe COVID-19 outcomes were similar throughout pandemic epochs in unvaccinated people with RDs. Ongoing efforts, including vaccination, are needed to reduce COVID-19 severity in this population, particularly in those with medical and social vulnerabilities identified in this study., (© 2023 American College of Rheumatology.)

Objectives: To evaluate the in vitro effect of tofacitinib on autophagy activity of psoriatic arthritis (PsA) fibroblast-like synoviocytes (FLS), and to confirm its activity on inflammatory and invasive properties of FLS and synovial cells, deepening the impact on mitochondrial function., Methods: FLS, peripheral blood mononuclear cells (PBMCs), and synovial cells from active PsA patients were cultured with tofacitinib 1 μM or vehicle control for 24 h. Autophagy was measured by Western blot and by fluorescence microscopy. Chemokines/cytokines released into culture supernatants were quantified by ELISA, while invasive properties of FLS by migration assays. Specific mitochondrial probes were adopted to measure intracellular reactive oxygen species (ROS), mitochondrial potential, morphology, turnover and mitophagy. Oxygen consumption rate (OCR), reflecting oxidative phosphorylation, was quantified using the Seahorse technology. Differences were determined by adopting the non-parametric Wilcoxon signed rank test., Results: 18 patients with moderately-to-severely active PsA were enrolled. Tofacitinib significantly increased the levels of the autophagy markers LC3-II and ATG7 in PsA FLS compared to vehicle control, suggesting an increase in spontaneous autophagy activity; no effect was highlighted in PBMCs and synovial cells cultures. Tofacitinib reduced migration properties of PsA FLS, and reduced MCP-1 and IL-6 release into FLS and synovial cells cultures supernatants. Furthermore, tofacitinib decreased intracellular ROS production, increased basal OCR, ATP production and maximal respiratory capacity, and enhanced mitophagy and mitochondrial turnover., Conclusions: The JAK inhibitor tofacitinib reduces the pro-invasive and pro-inflammatory properties of PsA FLS. Autophagy induction and mitochondrial quality control modulation by tofacitinib might contribute to FLS function restoration., Competing Interests: Declaration of competing interest ES has received research support from AbbVie and Lilly and consulting/speaker's fees from AbbVie, Galapagos, Lilly, Novartis, Astra-Zeneca and Amgen.

Background: Inflammatory arthritis (IAs), such as rheumatoid arthritis (RA) and psoriatic arthritis (PsA), are characterized by the presence of chronic synovitis. The Krenn's synovitis score (KSS), a simple tool detectable by haematoxylin/eosin staining of synovial biopsy samples, allows the discrimination between high-grade and low-grade synovitis. The aim of this study was to identify the clinical associations of KSS and to evaluate the relationship between high-grade synovitis and treatment response in IA patients., Methods: Clinical, laboratory and ultrasound data were retrieved from RA and PsA patients recruited in the prospective MATRIX cohort study. Inclusion criteria were age≥18 years, RA or PsA diagnosis, and presence of active disease with eligibility to start/modify therapy. Patients underwent ultrasound-guided synovial biopsy of one of the most involved joints before starting/modifying treatment according to treat-to-target strategy. The samples were analysed by an expert pathologist for KSS calculation. Univariable and multivariable logistic regression analyses were performed to evaluate the relationship between KSS and baseline variables. The association between KSS and treatment response at 24 weeks of follow-up was investigated in univariable logistic regression analysis., Results: 53 patients, 34 RA and 19 PsA, completed 24 weeks of follow-up after synovial biopsy. Patients were either treatment naïve (N=6, 11%), csDMARDs-experienced (N=46, 87%) or b/tsDMARDs-experienced (N=20, 38%). Median KSS was 6.00 (Q1-Q3 4.00-7.00) in RA and 4.00 (3.00-6.00) in PsA (p=0.040), and inflammatory infiltrates score was significantly higher in RA than in PsA patients (median 3.00 vs 2.00, p=0.021). In multivariable analysis, synovial effusion in the biopsied joint (OR 9.26, 95%CI 2.12-53.91) and erythrocyte sedimentation rate (ESR) (OR 1.04, 95%CI 1.01-1.08) associated with high KSS. High-grade synovitis significantly associated with a higher probability of achieving DAS28 remission, ACR20/50 response, and Boolean2.0 remission, independently from diagnosis., Conclusion: Several markers of pro-inflammatory pathways associated with the presence of high-grade synovitis, and patients with higher KSS shared a higher probability of treatment targets achievement in the follow up. The integration of a simple and feasible tool like KSS in the clinical and prognostic stratification of patients with IA might help in intercepting patients with a disease more prone to respond to available treatment paradigms., Competing Interests: ES has received research support from AbbVie and Lilly and consulting/speaker’s fees from AbbVie, Galapagos, Lilly, Novartis, Astra-Zeneca and Amgen.

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.

Background: Major improvements in the management of rheumatoid arthritis (RA) have made clinical remission an achievable and desirable goal but, despite the relevance gained by a profound disease suppression, many patients with RA still miss clinical remission due to several factors influencing disease activity, including treatment adherence., Objective: To evaluate the effect of adherence to conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) on the achievement of clinical remission in a cohort of patients with new-onset inflammatory arthritis., Study Design: A prospective cohort study was conducted using the ELECTRA database, which consists of clinical data from patients followed at the IRCCS Policlinico San Matteo Foundation (Pavia, Italy), linked to regional administrative healthcare databases., Methods: We enrolled patients with new-onset active disease between January 2006 and December 2013 and followed them until their first clinical remission or end of follow-up (December 2015). To assess the association of csDMARD adherence with clinical remission, we estimated the csDMARD proportion of days covered (PDC) during follow-up. PDC was added to the main clinical adjustment covariates as a time-dependent variable in a proportional hazard Cox regression model., Results: The cohort included 324 patients with a mean (SD) age of 58 (13.9) and predominantly female (74.5%). A total of 219 patients (67.6%) achieved clinical remission during follow-up and 85 (26.2%) in the first 6 months (early clinical remission). Cox regression models showed that a 10% increment of PDC increased the probability of achieving clinical remission by 10% ( p  < 0.001) and the probability of early clinical remission by 21% ( p  = 0.03)., Conclusion: Patients at disease onset with higher adherence to csDMARDs were more likely to achieve clinical remission and early clinical remission. Our study highlighted the importance of close monitoring of patients to increase their likelihood of following therapeutic indications and achieving favorable disease outcomes, such as lower disability., Competing Interests: Carlo Alberto Scirè received research grants from Abbvie and Lilly.

Introduction: Data concerning SARS-CoV-2 in patients affected by SLE are contradicting.The aim of this study was to investigate disease-related differences in COVID-19 prognosis of patients affected by rheumatic diseases before vaccination; we tested the hypothesis that patients with SLE may have a different outcome compared with those with rheumatoid arthritis (RA) or spondyloarthritis (SPA)., Methods: We analysed data from the national CONTROL-19 Database with a retrospective, observational design, including rheumatic patients affected by COVID-19. The principal outcome measure was hospitalisation with death or mechanical ventilation. Differences between SLE, RA and SPA were analysed by univariable and multivariable logistic regression models., Results: We included 103 patients with SLE (88.2% female, mean age 48.9 years, 50.4% active disease), 524 patients with RA (74.4% female, mean age 60.6 years, 59.7% active disease) and 486 patients with SPA (58.1% female, mean age 53.2 years, 58% active disease).Outcome prevalence was not different between patients with SLE and those with RA (SLE 24.5%, RA 25.6%), while patients with SPA showed a more favourable outcome compared with those with SLE (SPA 15.9%); data from the multivariable analysis confirmed this result.In SLE, age >65 years (OR 17.3, CI 5.51 to 63.16, p<0.001), hypertension (OR 6.2, CI 2.37 to 17.04, p<0.001) and prednisone (PDN) use (OR 3.8, CI 1.43 to 11.39, p=0.01) were associated with severe outcomes, whereas hydroxychloroquine use was found to be protective (OR 0.3, CI 0.14 to 0.91, p=0.03)., Conclusion: Our data suggest that patients with SLE and RA do not show a different COVID-19 outcome, while patients with SPA have a more favourable disease course compared with those with SLE. Risk of hospitalisation with ventilation or death was associated with age >65 years, hypertension and PDN use in patients with SLE., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Systemic lupus erythematosus (SLE) is characterized by multisystemic clinical manifestations ranging from a relatively mild involvement to potentially life-threatening complications. Due to this complexity, a multidisciplinary (MD) approach is the best strategy for optimizing patients' care. The main aim of this systematic literature review (SLR) was to scrutinize the published data regarding the MD approach for the management of SLE patients. The secondary objective was to evaluate the outcomes of the MD approach in SLE patients. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were used. We performed an SLR to retrieve articles available in English or Italian listed in PubMed, Embase, Cinahl, and Cochrane Library concerning the MD approach used in observational studies and clinical trials. Four independent reviewers performed the study selection and data collection. Of 5451 abstracts evaluated, 19 studies were included in the SLR. The MD approach was most frequently described in the context of SLE pregnancy, reported in 10 papers. MD teams were composed of a rheumatologist, except for one cohort study; a gynecologist; a psychologist; a nurse; and other health professionals. MD approaches had a positive impact on pregnancy-related complications and disease flares and improved SLE psychological impact. Although international recommendations advise an MD approach for managing SLE, our review highlighted the paucity of data supporting this strategy, with most of the available evidence on the management of SLE during pregnancy.

Background: Electronic health databases are used to identify people at risk of poor outcomes. Using electronic regional health databases (e-RHD), we aimed to develop and validate a frailty index (FI), compare it with a clinically based FI, and assess its association with health outcomes in community-dwellers with SARS-CoV-2., Methods: Data retrieved from the Lombardy e-RHD were used to develop a 40-item FI (e-RHD-FI) in adults (i.e., aged ≥18 years) with a positive nasopharyngeal swab polymerase chain reaction test for SARS-CoV-2 by May 20, 2021. The considered deficits referred to the health status before SARS-CoV-2. The e-RHD-FI was validated against a clinically based FI (c-FI) obtained from a cohort of people hospitalized with COVID-19 and in-hospital mortality was evaluated. e-RHD-FI performance was evaluated to predict 30-day mortality, hospitalization, and 60-day COVID-19 WHO clinical progression scale, in Regional Health System beneficiaries with SARS-CoV-2., Results: We calculated the e-RHD-FI in 689,197 adults (51.9% females, median age 52 years). On the clinical cohort, e-RHD-FI correlated with c-FI and was significantly associated with in-hospital mortality. In a multivariable Cox model, adjusted for confounders, each 0.1-point increment of e-RHD-FI was associated with increased 30-day mortality (Hazard Ratio, HR 1.45, 99% Confidence Intervals, CI: 1.42-1.47), 30-day hospitalization (HR per 0.1-point increment = 1.47, 99%CI: 1.46-1.49), and WHO clinical progression scale (Odds Ratio = 1.84 of deteriorating by one category, 99%CI 1.80-1.87)., Conclusion: The e-RHD-FI can predict 30-day mortality, 30-day hospitalization, and WHO clinical progression scale in a large population of community-dwellers with SARS-CoV-2 test positivity. Our findings support the need to assess frailty with e-RHD., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Rebora, Scirè, Occhino, Bortolan, Leoni, Cideni, Zucchelli, Focà, Marengoni, Bellelli and Valsecchi.)

Objective: Early diagnosis and tight control improve outcomes of rheumatoid arthritis (RA). However, whether establishing an early arthritis clinic (EAC) is sustainable for national health systems is not known. This analysis aimed to compare effectiveness and costs of an EAC compared to patients followed by the current standard of care., Methods: A retrospective study on administrative health databases of patients with a new diagnosis of RA was conducted: 430 patients followed in an EAC were enrolled, and 4 non-EAC controls were randomly matched for each. During 2 years of follow-up, the mean health care costs (outpatient, inpatient, pharmaceutical, and global) and 3 effectiveness measures (number and length of hospitalization and quality of care) of the EAC and non-EAC were estimated. The incremental cost-effectiveness ratio was calculated as well as the cost-effectiveness acceptability curve., Results: The cohorts included patients with a mean age of 55.4 years, and 1,506 patients (70%) were female. The mean pharmaceutical (2,602 versus 1,945 euros) and outpatient (2,447 versus 1,778 euros) costs were higher in the EAC cohort. Conversely, a higher rate of non-EAC patients had a low adherence to quality-of-care indicators. The expected number of hospitalizations and the length of stay were statistically significantly higher in the non-EAC versus EAC., Conclusion: Despite an expected increase in outpatient costs (visits and diagnostic tests) and pharmaceutical costs, the reduction in terms of number and length of hospitalizations and the higher adherence to international quality-of-care guidelines support the effectiveness of the EAC model., (© 2022 The Authors.

Objective: This study is a sub-analysis from the patient cohort of the STARTER (Sonographic Tenosynovitis Assessment in RheumaToid arthritis patiEnts in Remission) study. The aim was to evaluate differences in ultrasound-detected joint and/or tendon involvement between patients receiving therapies based on a combination of conventional synthetic DMARDs (csDMARDs) and biologic DMARDs (bDMARDs) and those who were treated with either csDMARDs or bDMARDs in monotherapy., Material and Methods: Four hundred and twenty-seven consecutive patients with a diagnosis of RA were recruited between October 2013 and June 2014. They were divided into three subgroups based on their therapy at baseline: patients with bDMARD in monotherapy, patients with csDMARD in monotherapy and patients in combination therapy (csDMARD + bDMARD). At baseline, 6 months and 12 months, a clinical examination (28 joint count) and an ultrasound evaluation were performed in each patient. A score of grey-scale (GS) and power Doppler (PD) synovitis and tenosynovitis was calculated based on the OMERACT scoring systems., Results: Two hundred and fifty-six patients completed the observation period: 48 patients from the bDMARD group (18.75%), 152 patients from the csDMARD group (59.38%) and 56 patients from csDMARD + bDMARD group (21.88%). The analysis showed that GS tenosynovitis and PD tenosynovitis are better controlled in combination therapy than they are with csDMARD alone (P = 0.025 and P = 0.047, respectively); for PD synovitis, there was a better response in those who were treated with the combination therapy when compared with the patients receiving csDMARD (P = 0.01) or bDMARD (P = 0.02) alone., Conclusions: The analysis showed a lower prevalence of subclinical inflammatory manifestations detected with ultrasound imaging in those patients treated with the combination therapy than in those in monotherapy., (© The Author(s) 2022.

Objectives: To develop an Outcome Measures in Rheumatology (OMERACT) ultrasonography score for monitoring disease activity in giant cell arteritis (GCA) and evaluate its metric properties., Methods: The OMERACT Instrument Selection Algorithm was followed. Forty-nine members of the OMERACT ultrasonography large vessel vasculitis working group were invited to seven Delphi rounds. An online reliability exercise was conducted using images of bilateral common temporal arteries, parietal and frontal branches as well as axillary arteries from 16 patients with GCA and 7 controls. Sensitivity to change and convergent construct validity were tested using data from a prospective cohort of patients with new GCA in which ultrasound-based intima-media thickness (IMT) measurements were conducted at weeks 1, 3, 6, 12 and 24., Results: Agreement was obtained (92.7%) for the OMERACT GCA Ultrasonography Score (OGUS), calculated as follows: sum of IMT measured in every segment divided by the rounded cut-off values of IMTs in each segment. The resulting value is then divided by the number of segments available. Thirty-five members conducted the reliability exercise, the interrater intraclass correlation coefficient (ICC) for the OGUS was 0.72-0.84 and the median intrareader ICC was 0.91. The prospective cohort consisted of 52 patients. Sensitivity to change between baseline and each follow-up visit up to week 24 yielded standardised mean differences from -1.19 to -2.16, corresponding to large and very large magnitudes of change, respectively. OGUS correlated moderately with erythrocyte sedimentation rate, C reactive protein and Birmingham Vasculitis Activity Score (corr coeff 0.37-0.48)., Conclusion: We developed a provisional OGUS for potential use in clinical trials., Competing Interests: Competing interests: CDe has received grant support from AbbVie and consulting/speaker’s fees from Abbvie, Eli Lilly, Janssen, Galapagos, Novartis, Pfizer, Sparrow, Roche and Sanofi, all unrelated to this manuscript.
