RESUMO

OBJECTIVE: To evaluate the discriminatory ability of ultrasound in calcium pyrophosphate deposition disease (CPPD), using microscopic analysis of menisci and knee hyaline cartilage (HC) as reference standard. METHODS: Consecutive patients scheduled for knee replacement surgery, due to osteoarthritis (OA), were enrolled. Each patient underwent ultrasound examination of the menisci and HC of the knee, scoring each site for presence/absence of CPPD. Ultrasound signs of inflammation (effusion, synovial proliferation and power Doppler) were assessed semiquantitatively (0-3). The menisci and condyles, retrieved during surgery, were examined microscopically by optical light microscopy and by compensated polarised microscopy. CPPs were scored as present/absent in six different samples from the surface and from the internal part of menisci and cartilage. Ultrasound and microscopic analysis were performed by different operators, blinded to each other's findings. RESULTS: 11 researchers from seven countries participated in the study. Of 101 enrolled patients, 68 were included in the analysis. In 38 patients, the surgical specimens were insufficient. The overall diagnostic accuracy of ultrasound for CPPD was of 75%-sensitivity of 91% (range 71%-87% in single sites) and specificity of 59% (range 68%-92%). The best sensitivity and specificity were obtained by assessing in combination by ultrasound the medial meniscus and the medial condyle HC (88% and 76%, respectively). No differences were found between patients with and without CPPD regarding ultrasound signs of inflammation. CONCLUSION: Ultrasound demonstrated to be an accurate tool for discriminating CPPD. No differences were found between patents with OA alone and CPPD plus OA regarding inflammation.

RESUMO

OBJECTIVE: 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.

RESUMO

Due to the frequent presence of interstitial lung disease and widespread use of immunosuppressive treatment, systemic sclerosis (SSc) patients may be considered at risk for a more severe disease course and higher mortality when they develop Severe Acute Respiratory Syndrome - Coronavirus - 2 (SARS-CoV-2) virus infection. Therefore, with World Scleroderma Foundation endorsement, experts from different specialties including rheumatology, virology and clinical immunology gathered virtually to answer to the main practical clinical questions regarding SARS-CoV-2 infection coming from both patients and physicians. This preliminary advice is aligned with other national and international recommendations, adapted for SSc patients.

RESUMO

OBJECTIVE: To update the European League Against Rheumatism (EULAR) recommendations for the pharmacological treatment of psoriatic arthritis (PsA). METHODS: According to the EULAR standardised operating procedures, a systematic literature review was followed by a consensus meeting to develop this update involving 28 international taskforce members in May 2019. Levels of evidence and strengths of recommendations were determined. RESULTS: The updated recommendations comprise 6 overarching principles and 12 recommendations. The overarching principles address the nature of PsA and diversity of both musculoskeletal and non-musculoskeletal manifestations; the need for collaborative management and shared decision-making is highlighted. The recommendations provide a treatment strategy for pharmacological therapies. Non-steroidal anti-inflammatory drugs and local glucocorticoid injections are proposed as initial therapy; for patients with arthritis and poor prognostic factors, such as polyarthritis or monoarthritis/oligoarthritis accompanied by factors such as dactylitis or joint damage, rapid initiation of conventional synthetic disease-modifying antirheumatic drugs is recommended. If the treatment target is not achieved with this strategy, a biological disease-modifying antirheumatic drugs (bDMARDs) targeting tumour necrosis factor (TNF), interleukin (IL)-17A or IL-12/23 should be initiated, taking into account skin involvement if relevant. If axial disease predominates, a TNF inhibitor or IL-17A inhibitor should be started as first-line disease-modifying antirheumatic drug. Use of Janus kinase inhibitors is addressed primarily after bDMARD failure. Phosphodiesterase-4 inhibition is proposed for patients in whom these other drugs are inappropriate, generally in the context of mild disease. Drug switches and tapering in sustained remission are addressed. CONCLUSION: These recommendations provide stakeholders with an updated consensus on the pharmacological management of PsA, based on a combination of evidence and expert opinion.

RESUMO

OBJECTIVES: To describe and explore differences in formal regulations around sick leave and work disability (WD) for patients with rheumatoid arthritis (RA), as well as perceptions by rheumatologists and patients on the system's performance, across European countries. METHODS: We conducted three cross-sectional surveys in 50 European countries: one on work (re-)integration and social security (SS) system arrangements in case of sick leave and long-term WD due to RA (one rheumatologist per country), and two among approximately 15 rheumatologists and 15 patients per country on perceptions regarding SS arrangements on work participation. Differences in regulations and perceptions were compared across categories defined by gross domestic product (GDP), type of social welfare regime, European Union (EU) membership and country RA WD rates. RESULTS: Forty-four (88%) countries provided data on regulations, 33 (75%) on perceptions of rheumatologists (n=539) and 34 (77%) on perceptions of patients (n=719). While large variation was observed across all regulations across countries, no relationship was found between most of regulations or income compensation and GDP, type of SS system or rates of WD. Regarding perceptions, rheumatologists in high GDP and EU-member countries felt less confident in their role in the decision process towards WD (ß=-0.5 (95% CI -0.9 to -0.2) and ß=-0.5 (95% CI -1.0 to -0.1), respectively). The Scandinavian and Bismarckian system scored best on patients' and rheumatologists' perceptions of regulations and system performance. CONCLUSIONS: There is large heterogeneity in rules and regulations of SS systems across Europe in relation to WD of patients with RA, and it cannot be explained by existing welfare regimes, EU membership or country's wealth.

RESUMO

OBJECTIVES: To assess the reliability of the OMERACT ultrasound (US) definitions for the identification of calcium pyrophosphate deposition disease (CPPD) at the metacarpal-phalangeal, triangular fibrocartilage of the wrist (TFC), acromioclavicular (AC) and hip joints. METHODS: A web-based exercise and subsequent patient-based exercise were carried out. A panel of 30 OMERACT members, participated at the web-based exercise by evaluating twice a set of US images for the presence/absence of CPPD. Afterwards, 19 members of the panel met in Siena, Italy, for the patient-based exercise. During the exercise, all sonographers examined twice eight patients for the presence/absence of CPPD at the same joints. Intraoberserver and interobserver kappa values were calculated for both exercises. RESULTS: The web-based exercise yielded high kappa values both in intraobserver and interobserver evaluation for all sites, while in the patient-based exercise, inter-reader agreement was acceptable for the TFC and the AC. TFC reached high interobserver and intraobserver k values in both exercises, ranging from 0.75 to 0.87 (good to excellent agreement). AC reached moderate kappa values, from 0.51 to 0.85 (moderate to excellent agreement) and can readily be used for US CPPD identification. CONCLUSIONS: Based on the results of our exercise, the OMERACT US definitions for the identification of CPPD demonstrated to be reliable when applied to the TFC and AC. Other sites reached good kappa values in the web-based exercise but failed to achieve good reproducibility at the patient-based exercise, meaning the scanning method must be further refined.

RESUMO

OBJECTIVES: Our aim was to use the opportunity provided by the European Scleroderma Observational Study to (1) identify and describe those patients with early diffuse cutaneous systemic sclerosis (dcSSc) with progressive skin thickness, and (2) derive prediction models for progression over 12 months, to inform future randomised controlled trials (RCTs). METHODS: The modified Rodnan skin score (mRSS) was recorded every 3 months in 326 patients. 'Progressors' were defined as those experiencing a 5-unit and 25% increase in mRSS score over 12 months (±3 months). Logistic models were fitted to predict progression and, using receiver operating characteristic (ROC) curves, were compared on the basis of the area under curve (AUC), accuracy and positive predictive value (PPV). RESULTS: 66 patients (22.5%) progressed, 227 (77.5%) did not (33 could not have their status assessed due to insufficient data). Progressors had shorter disease duration (median 8.1 vs 12.6 months, P=0.001) and lower mRSS (median 19 vs 21 units, P=0.030) than non-progressors. Skin score was highest, and peaked earliest, in the anti-RNA polymerase III (Pol3+) subgroup (n=50). A first predictive model (including mRSS, duration of skin thickening and their interaction) had an accuracy of 60.9%, AUC of 0.666 and PPV of 33.8%. By adding a variable for Pol3 positivity, the model reached an accuracy of 71%, AUC of 0.711 and PPV of 41%. CONCLUSIONS: Two prediction models for progressive skin thickening were derived, for use both in clinical practice and for cohort enrichment in RCTs. These models will inform recruitment into the many clinical trials of dcSSc projected for the coming years. TRIAL REGISTRATION NUMBER: NCT02339441.

RESUMO

OBJECTIVE: To assess the efficacy and safety of oral decernotinib (VX-509; Vertex Pharmaceuticals) monotherapy in a 12-week, randomized, double-blind, placebo-controlled, dose-ranging study of patients with rheumatoid arthritis (RA). METHODS: Two hundred four adults with active RA who had been unsuccessfully treated with ≥1 disease-modifying antirheumatic drug were administered placebo tablets or decernotinib twice a day at dosages of 25 mg, 50 mg, 100 mg, or 150 mg. Primary measures of efficacy at week 12 were the response rate according to the American College of Rheumatology 20% improvement criteria (ACR20) and mean change from baseline in the Disease Activity Score in 28 joints using the C-reactive protein level (DAS28-CRP). RESULTS: At week 12, the ACR20 response rates were 39.0%, 61.0%, 65.0%, and 65.9% in the 25-mg, 50-mg, 100-mg, and 150-mg groups, respectively, and were significantly higher in the 50-mg group (P = 0.007) and the 100-mg and 150-mg groups (P = 0.002) as compared to the response rates in the placebo group (29.3%). The mean change from baseline in DAS28-CRP was greater in the 50-mg, 100-mg, and 150-mg groups as compared to the placebo group (P < 0.001). Decernotinib treatment resulted in higher ACR50 and ACR70 response rates, more patients with DAS28-CRP scores <2.6, and improvements in the Health Assessment Questionnaire disability index as compared to placebo. The most common adverse events in any decernotinib group were nausea (6.1%), headache (4.3%), an increase in levels of alanine aminotransferase (4.3%), and hypercholesterolemia (3.7%). In the groups receiving decernotinib, there was an increased risk of infections and increased liver transaminase levels. CONCLUSION: Decernotinib was efficacious in improving clinical signs and symptoms of RA at week 12 at dosages of 50-150 mg twice a day. Infections and increases in liver transaminase and lipid levels were noted as potential safety signals.

RESUMO

The aim of this study is to assess the prognostic value of major provisional criteria for the development of systemic sclerosis (SSc) in primary Raynaud's phenomenon (RP) patients. We retrospectively studied the chart of 497 patients with primary RP in whom anticentromere (ACA) and antitopoisomerase I (ATA) antibodies tests and a capillary reading were available. Sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratios (LHR+), negative likelihood ratios (LHR-), odds ratio (OR), and area under the receiver operating characteristics curve (AUC) of those criteria were assessed to predict the development of SSc. During the average follow-up of 2.3 ± 1.9 years, 159 (32 %) patients evolved to SSc, 245 (49.3 %) evolved to other connective tissue diseases, and 93 (18.7 %) patients did not progress. The SSc pattern predicted SSc satisfactorily (LHR+ 4.12, LHR- 0.07, OR 63, AUC 0.819; P < 0.001). ACA were not significantly associated with the development of SSc (LHR+ 1.19, LHR- 0.9, OR 1.32, AUC 0.538, P = 0.156). ATA were significantly associated with the development of SSc (LHR+ 9.32, LHR- 0.67, OR 15.13, AUC 0.777; P < 0.001). Both SSc pattern and ACA or ATA were significantly associated with the development of SSc (LHR+ 2.98, LHR- 0.70, OR 4.2, AUC 0.674; P < 0.001 vs. LHR+ 16, LHR- 0.68, OR 24, AUC 0.819; P < 0.001, respectively). SSc pattern or ATA as independent risk factors, as well as following two parameters together (SSc pattern and ATA or SSc pattern and ACA) were good predictors for the development of SSc.

RESUMO

The aim of this study was to assess the association between Raynaud's phenomenon (RP) and specific capillaroscopic findings in patients with SLE and particular clinical manifestations of the disease. A total of 79 patients with SLE were included in the study: 44 of them (43 women) with RP and 35 (32 women) age-, sex-, and disease-duration-matched patients with SLE without RP. Demographic variables, clinical manifestations, laboratory and nailfold capillaroscopy findings were compared between the two groups. Central nervous systemic involvements (P = 0.0038) and peripheral neuropathy (P = 0.0336) were significantly more common in SLE patients with RP, while secondary Sjögren's syndrome (P = 0.0363) was more common in SLE patients without RP. RP occurred in 52 % of patients before SLE onset while 48 % of patients developed RP after they had been diagnosed with SLE. Arthritis/arthralgia (P = 0.0073) was significantly more common in patients who had been diagnosed with RP before the onset of SLE, while mucosal ulcers were more common in patients who contracted RP after the onset of SLE (P = 0.0258). Enlarged capillaries (P = 0.0482), presence of avascular areas (P = 0.0476), capillary hemorrhages (P = 0.0482), and granular blood flow (P = 0.0482) were more common in patients with SLE who also suffered from RP, than in patients with SLE without RP. The frequency of normal (63.6 vs. 82.9 %, P = 0.100) and nonspecific (25 vs. 17.1 %, P = 0.5696) capillaroscopy findings were similar in either groups. Scleroderma-like pattern of capillaroscopy finding was only found in patients with RP [(11.4 %), P = 0.0482]. RP in our patients with SLE was associated with specific clinical manifestations, indicating that prognostic relevance of RP in SLE should be evaluated.

RESUMO

To assess the prognostic value of the age at onset of Raynaud's (RP) and of a history of exacerbation of RP attacks for the development of connective tissue disease (CTD) in patients initially found to have primary Raynaud's. 3,035 patients with primary RP (2,702 women and 333 men) were followed for an average of 4.8 years (range from 1 to 10 years). At baseline and every 6 months, they were screened for signs and symptoms of CTD. At 4.8 years of follow-up, 54.7 % patients remained as primary RP, 8.1 % had developed suspected secondary RP, and 37.2 % had developed a definite CTD. Primary RP patients had an earlier onset of RP (mean age of 32.2 years) than those with suspected (mean age 36.5 years, P = .007) or definite secondary RP associated with CTD (mean age of 39.8 years, P = .004). RP beginning before the age of forty was not significantly associated with the development of CTD. Conversely, the appearance of RP after the age of 40 was significantly associated with the development of CTD (P = .00001). Worsening of RP attacks predicted the development of CTD, especially systemic sclerosis (relative risk [RR] of 1.42), scleroderma overlap syndrome (RR of 1.18), and mixed CTD (RR of 1.18). Patients whose onset of RP occurred past 40 years of age and those with worsening RP attacks were at risk for the future development of CTD.

RESUMO

OBJECTIVE: To evaluate the effect of a tumor necrosis factor-α (TNF-α) inhibitor (etanercept) on innate inflammatory and Th17 cytokines in patients with rheumatoid arthritis (RA). METHODS: Serum samples were collected from 40 patients with active RA refractory to conventional disease-modifying antirheumatic drugs who initiated therapy with etanercept plus methotrexate (MTX). Treatment response was assessed at Week 24 according to the European League Against Rheumatism response criteria. Serum levels of interleukin 6 (IL-6), TNF-α, IL-32, IL-23, IL-17A, IL-21, and IL-22 were measured in patients with RA and 25 healthy controls. RESULTS: Patients with RA had increased levels of IL-6 (p < 0.001), IL-32 (p < 0.001), IL-23 (p < 0.001), and a trend toward increased IL-21 in the sera compared to controls. At 24 weeks' posttreatment, followup serum samples of etanercept responders had decreased levels of IL-6 (p < 0.001) and increased IL-21 (p < 0.05) and IL-32 (p < 0.001), while there were no differences in cytokine levels in non-responders. Serum IL-6 levels were positively correlated with levels of erythrocyte sedimentation rate (r = 0.458, p < 0.01), C-reactive protein (r = 0.593, p < 0.01), and 28-joint Disease Activity Score (r = 0.432, p < 0.01) at baseline. Serum IL-21 levels were positively correlated with levels of rheumatoid factor (r = 0.513, r = 0.633, both p < 0.01) and antimutated citrullinated vimentin antibodies (r = 0.515, p < 0.01; r = 0.428, p < 0.05) at baseline and after 24 weeks of treatment with etanercept. CONCLUSION: Multiple inflammatory pathways contribute to persistent chronic inflammation in RA. In contrast to nonresponders, etanercept therapy modulated serum cytokine levels and caused a marked decrease of IL-6 levels in responders. IL-21 might be involved in the regulation of autoantibody production in RA.

RESUMO

To assess the prognostic value of scleroderma pattern of nailfold capillary changes for the development of connective tissue diseases (CTD) in subjects with primary Raynaud's phenomenon (RP). The study included 3,029 consecutive patients with primary RP who had been followed at 6-month intervals during the mean of 4.8 years. The pathological features of nailfold capillaroscopy were recorded in all patients who had neither clinical nor serological signs of a CTD. In patients who developed CTD, capillary changes obtained 6 months prior to diagnosis were analyzed. A possible relationship between capillary changes and the presence of associated CTD was assessed. At the end of follow-up, 1,660 (54,8%) patients have still the primary RP, 246 (8,1%) had suspected secondary RP, and 1,123 (37,1%) patients developed CTD (363 undifferentiated CTD, 263 systemic sclerosis, 143 systemic lupus erythematosus, 106 rheumatoid arthritis, 102 Sjögren's syndrome, 61 overlap syndrome, 30 vasculitides, 24 mixed CTD, 19 polymyositis, 7 dermatomyositis, and 5 primary antiphospholipid syndrome). Scleroderma pattern were significantly associated with the development of systemic sclerosis [P = .00001, sensitivity 94%, specificity 92%, positive predictive value 52%, negative predictive value 99%, and odds ratio 163 (95% CI, 97,9-271,5)], as well as dermatomyositis (P = .0004), overlap syndrome with signs of systemic sclerosis (P = .0001), and mixed connective tissue disease (P = .007). Capillary microscopy is effective method for differentiation between primary and secondary RP and useful tool for the prediction of scleroderma spectrum disorders in RP patients.

RESUMO

OBJECTIVE: To compare an ultrasonographic (US) scoring system of salivary glands with scintigraphy and salivary gland biopsy, in order to evaluate its diagnostic value in primary Sjögren's syndrome (SS). METHODS: In 135 patients with suspected SS, the grades of 5 US measures of both parotid and submandibular salivary glands were scored (0-48 scale). Diagnosis of primary SS was established following the American-European Consensus Group criteria of 2002. The patients' total scintigraphic score (0-12 scale) was determined and the histopathological changes of minor salivary glands graded. Area under the receiver-operating characteristic (ROC) curve was employed to evaluate the diagnostic value of the US scoring system. RESULTS: Primary SS was diagnosed in 107 (79.2%) patients and the remaining 28 subjects (20.8%) constituted the control group. US changes of salivary glands were established in 98/107 patients with SS and in 14/28 controls. Mean US score was 26 in SS patients and 6 in controls. Through ROC curves, US arose as the best performer (0.95 +/- 0.01), followed by scintigraphy (0.86 +/- 0.31). Setting the cutoff score for US at 19 resulted in the best ratio of specificity (90.8%) to sensitivity (87.1%), while setting the cutoff scintigraphic score at 6 resulted in specificity of 86.1% and sensitivity of 67.1%. Among 70 patients with US score >or= 19, a scintigraphic score > 6 was recorded in 54/70 (77.1%) and positive biopsy findings in 62/70 (88.5%) patients. CONCLUSION: We show high diagnostic accuracy of a novel US scoring system of salivary glands (0-48) in patients with primary SS comparable to invasive methods, i.e., scintigraphy and salivary gland biopsy.
