RESUMO
OBJECTIVES: To test the association of use of antimalarials with the overall safety of treatment in RA patients receiving one or multiple courses of biologic (b)DMARDs or a Janus kinase inhibitor (JAKi). METHODS: BiobadaBrasil is a multicentric registry-based cohort study of Brazilian patients with rheumatic diseases starting their first bDMARD or JAKi. The present analysis includes RA patients recruited from January 2009 to October 2019, followed up over one or multiple (up to six) courses of treatment (latest date, 19 November 2019). The primary outcome was the incidence of serious adverse events (SAEs). Total and system-specific adverse events (AEs) and treatment interruption served as secondary outcomes. Negative binomial regression with generalized estimating equations (to estimate multivariate incidence rate ratios, mIRR) and frailty Cox proportional hazards models were used for statistical analyses. RESULTS: The number of patients enrolled was 1316 (2335 treatment courses, 6711 patient-years [PY]; 1254.5 PY on antimalarials). The overall incidence of SAEs was 9.2/100 PY. Antimalarials were associated with reduced risk of SAEs (mIRR: 0.49; 95% CI: 0.36, 0.68; P < 0.001), total AEs (0.68; 95% CI: 0.56, 0.81; P < 0.001), serious infections (0.53; 95% CI: 0.34, 0.84; P = 0.007) and total hepatic AEs (0.21; 95% CI: 0.05, 0.85; P = 0.028). Antimalarials were also related to better survival of treatment course (P = 0.003). There was no significant increase in the risk of cardiovascular AEs. CONCLUSION: Among RA patients on treatment with bDMARDs or JAKi, concomitant use of antimalarials was associated with reduced the incidence of serious and total AEs and with longer treatment course survival.

OBJECTIVES: To review the effectiveness of manual thrombectomy (MT) in a series of patients with ST-elevation myocardial infarction (STEMI) exclusively presenting with TIMI 0-1 flow undergoing percutaneous coronary intervention (PCI), in accordance to the angiographically estimated area at risk (AAR). Second, to assess major in-hospital clinical events, emphasizing neurological outcomes. BACKGROUND: The routine utilization of MT in STEMI is not recommended. However, in recent trials, a significant proportion of patients had neither large thrombus burden nor a totally occluded coronary segment, neutralizing the expected benefits of MT. In addition, the efficiency of MT to remove thrombus has rarely been addressed. Finally, MT diminished distal embolization, which has been related to mortality. RESULTS: In 850 consecutive STEMI-patients, MT was utilized in 525 (62%) and it was considered efficient (TIMI 2-3 flow after MT) in 445 (85%). We found a significant interaction between the AAR and the effectiveness of MT to reduce infarct size (P-interaction = 0.014). In patients having AAR ≥ 28% (n = 184), efficient MT conferred lesser infarct size compared to inefficient MT (Ln-transformed peak CK): 7.87 ± 0.86 versus 8.36 ± 0.41 IU/L, P = 0.005, with no impact for AAR <28%. Clinical outcomes including stroke between MT and PCI-only groups were not different. CONCLUSION: In comparison with the group where MT was inefficient, efficient MT may modestly reduce final infarct size without a significant clinical benefit. In comparison with PCI-only, no difference was found regarding stroke. © 2017 Wiley Periodicals, Inc.

BACKGROUND AND OBJECTIVE: Cytokines have an important role in the pathogenesis of rheumatoid arthritis (RA). Although plasma levels of IL-6 have been related to musculoskeletal ultrasound (MSUS) synovitis in early DMARD-naïve RA, there are no similar studies in established disease. METHODS: 64 RA patients treated with non-biological DMARDs and 30 healthy controls were included in this prospective cross-sectional study. A blood sample was taken before evaluation of disease activity (DAS28) and ultrasonography (all tests performed in a blinded fashion). MSUS was performed by one of two ultrasound-trained rheumatologists on 10 joints of both hands. Gray scale (GS) and pD (power Doppler) synovitis were evaluated using a semi-quantitative scale (0-3) in individual joints, and their sum (score 10) was calculated. Plasma cytokines (IL-2, IL-4, IL-6, IL-10, IL-17, TNF, IFN-γ, and VEGF) were quantified by flow cytometry. RESULTS: Levels of all cytokines, excepting VEGF, were significantly higher in RA patients than in controls (P⩽0.05). In RA patients, IL-6, but not other cytokines, correlated positively with DAS28 and swollen joint count (P⩽0.01), as well as with 10-joint pD score, and GS and pD of both wrists (P<0.01 for all tests). In multiple linear regression, the association of IL-6 with 10-joint pD score was maintained even after adjustment for DAS28. However, there was no correlation of IL-6 with tender joint count, 10-joint GS score, or presence of erosions. CONCLUSION: We demonstrated an association of inflammatory findings on MSUS and plasma IL-6 independently of DAS28 in established RA.

OBJECTIVE: A consensus meeting of representatives of 16 Latin American and Caribbean countries and the REAL-PANLAR group met in the city of Bogota to provide recommendations for improving quality of care of patients with rheumatoid arthritis (RA) in Latin America, defining a minimum standards of care and the concept of center of excellence in RA. METHODS: Twenty-two rheumatologists from 16 Latin American countries with a special interest in quality of care in RA participated in the consensus meeting. Two RA Colombian patients and 2 health care excellence advisors were also invited to the meeting. A RAND-modified Delphi procedure of 5 steps was applied to define categories of centers of excellence. During a 1-day meeting, working groups were created in order to discuss and validate the minimum quality-of-care standards for the 3 proposed types of centers of excellence in RA. Positive votes from at least 60% of the attending leaders were required for the approval of each standard. RESULTS: Twenty-two opinion leaders from the PANLAR countries and the REAL-PANLAR group participated in the discussion and definition of the standards. One hundred percent of the participants agreed with setting up centers of excellence in RA throughout Latin America. Three types of centers of excellence and its criteria were defined, according to indicators of structure, processes, and outcomes: standard, optimal, and model. The standard level should have basic structure and process indicators, the intermediate or optimal level should accomplish more structure and process indicators, and model level should also fulfill outcome indicators and patient experience. CONCLUSIONS: This is the first Latin American effort to standardize and harmonize the treatment provided to RA patients and to establish centers of excellence that would offer to RA patients acceptable clinical results and high levels of safety.

Background: Histoplasmosis is the second most frequent granulomatous disease in patients treated with tumor necrosis factor (TNF)-α inhibitors, second only to tuberculosis. However, there is limited information about pre-therapy screening procedures and the need for preventive treatments for patients who will start immunobiologicals. Methods: This is a cohort study that evaluated the prevalence of histoplasmosis in asymptomatic HIV-negative patients before initiation of TNF-α inhibitors by testing for Histoplasma antigen in urine samples. The patients included completed a 180-day follow-up after the initiation of the biologics to assess the onset of symptoms suggestive of histoplasmosis. Results: From January 2021 to December 2022, 54 patients who were prescribed a TNF-α inhibitor agent for treating autoimmune diseases in centers in southern Brazil were included. In the screening before therapy, the prevalence of a positive urinary Histoplasma antigen test was 14.8%. None of the 54 patients developed histoplasmosis after 6 months of immunobiological therapy, including the eight patients who tested positive. Conclusion: The prevalence of Histoplasma capsulatum infection in chronic patients may be higher than expected, but the impact of latent infection in asymptomatic patients is still uncertain, including those starting treatment with immunobiological drugs such as TNF-α inhibitors. Our study did not identify risk factors for the diagnosis of disseminated histoplasmosis in this group, including a positive result in an antigen test performed before immunobiological therapy. To date, there is no evidence to recommend routine antigen-based screening or preventive therapy for histoplasmosis before initiating a TNF-α inhibitor.
Using a urine test for fungal infection to screen people without symptoms who are about to start taking immunobiologic medications This study looked at the prevalence of histoplasmosis, a fungal infection, in asymptomatic patients who were about to start treatment with TNF-α inhibitors, which are medications used for autoimmune diseases. The researchers tested urine samples for Histoplasma antigen before the patients started the treatment and followed them for 180 days after starting the medication to see if they developed any symptoms of histoplasmosis. The study included 54 patients in southern Brazil, and they found that 14.8% of the patients tested positive for the Histoplasma antigen before starting the treatment. However, none of the patients, including those who tested positive, developed histoplasmosis during the 6-month follow-up. The researchers concluded that histoplasmosis infection may be more common in these patients than previously thought, but it's still not clear if asymptomatic patients with a positive antigen test will develop the infection when starting TNF-α inhibitor treatment. The study did not find any specific risk factors for developing histoplasmosis in this group of patients, and based on their findings, they did not recommend routine screening or preventive therapy for histoplasmosis before starting TNF-α inhibitor treatment.
RESUMO
BACKGROUND: Treatment of rheumatoid arthritis (RA) has evolved dramatically in the last decade. However, little is known about the way rheumatologists in Latin America treat their patients in clinical practice, outside the scope of clinical trials. OBJECTIVE: The objective of this study was to describe treatment patterns at disease onset in early RA with data from a large, multicenter, multinational inception cohort of Latin American patients. METHODS: Consecutive patients with early RA (<1 year of disease duration as diagnosed by a rheumatologist) from 46 centers in 14 Latin American countries were enrolled in the study. Clinical data, laboratory assessments, and a detailed registry on type of prescriptions were collected at baseline and at 3, 6, 12, 18, and 24 months of follow-up. Hands and feet x-rays were obtained at baseline and at 12 and 24 months. All data were captured in Arthros 6.1 database. Continuous variables were expressed as means and SDs, and categorical variables were expressed as percentages and 95% confidence intervals (95% CIs). Only therapeutic data at baseline are presented, corresponding to the period between disease onset and second visit (3 months). RESULTS: A total of 1093 patients were included. Eighty-five percent were female, and 76% had a positive rheumatoid factor. Mean age at diagnosis was 46.5 (SD, 14.2) years, and mean disease duration at the first visit was 5.8 (SD, 3.8) months. Between baseline and second visit (3 months), 75% of patients (95% CI, 72%-78%) received disease-modifying antirheumatic drugs. Methotrexate (MTX) alone or in combination was the most frequently used (60.5%), followed by antimalarials (chloroquine or hydroxychloroquine, 32.1%), sulfasalazine (7.1%), and leflunomide (LEF, 4%). In 474 patients (43%), initiation of disease-modifying antirheumatic drugs was within the first month after the first visit. In addition, 290 patients (26%; 95% CI, 23%-29%) received combination therapy as initial treatment. The most frequently used combinations were MTX + chloroquine (45%), MTX + hydroxychloroquine (25%), and MTX + sulfasalazine (16%). Eleven patients (1%; 95% CI, 0.5%-1.8%) received biologics. Sixty-four percent (95% CI, 60%-66%) received corticosteroids. Of those, 80% (95% CI, 77%-84%) received 10 mg of oral prednisone or less. CONCLUSIONS: In this cohort of Latin American patients with early RA, most patients received MTX very early in their disease course. Combination therapy was used approximately in 1 of every 4 patients as initial therapy. Biologics were rarely used at this early stage, and low-dose prednisone was commonly used.

OBJECTIVE: To evaluate the safety of the methotrexate (MTX)-leflunomide (LEF) combination in rheumatoid arthritis (RA), comparing it with other therapeutic schemes involving conventional synthetic (cs-) and biologic (b-) disease-modifying antirheumatic drugs (DMARDs) or Janus kinase inhibitors (JAKi). METHODS: Patients with RA starting a treatment course with a csDMARD (without previous use of bDMARD or JAKi) or their first bDMARD/JAKi were followed up in a registry-based, multicentric cohort study in Brazil (BiobadaBrasil). The primary outcome was the incidence of serious adverse events (SAEs); secondary outcomes included serious infections. Multivariate Cox proportional hazards models and propensity score matching analysis (PSMA) were used for statistical comparisons. RESULTS: In total, 1671 patients (5349 patient-years [PY]) were enrolled; 452 patients (1537 PY) received MTX + LEF. The overall incidence of SAEs was 5.6 per 100 PY. The hazard of SAEs for MTX + LEF was not higher than for MTX or LEF (adjusted HR [aHR] 1.00, 95% CI 0.76-1.31, P = 0.98). MTX + LEF presented a lower hazard of SAEs (aHR 0.56, 95% CI 0.36-0.88, P = 0.01) and infectious SAEs (aHR 0.48, 95% CI 0.25-0.94, P = 0.03) than bDMARDs/JAKi with MTX or LEF. MTX + LEF presented lower hazard of SAEs than MTX + sulfasalazine (SSZ; aHR 0.33, 95% CI 0.16-0.65, P = 0.002). Analysis using PSMA confirmed the results obtained with traditional multivariate Cox analysis. CONCLUSION: In our study, MTX + LEF presented a relatively good overall safety profile in comparison to MTX + SSZ and schemes involving advanced therapies in RA.

OBJECTIVE: To develop guidelines for Musculoskeletal Ultrasound (MSKUS) training for rheumatologists in the Americas. METHODS: A total of 25 Rheumatologists from 19 countries of the American Continent participated in a consensus-based interactive process (Delphi method) using 2 consecutive electronic questionnaires. The first questionnaire included the following: the relevance of organizing courses to teach MSKUS to Rheumatologists, the determination of the most effective educational course models, the trainee levels, the educational objectives, the requirements for passing the course(s), the course venues, the number of course participants per instructor, and the percentage of time spent in hands-on sessions. The second questionnaire consisted of questions that did not achieve consensus (>65%) in the first questionnaire, topics, and pathologies to be covered at each course MSKUS level. RESULTS: General consensus was obtained for MSKUS courses to be divided into 3 educational levels: basic, intermediate, and advanced. These courses should be taught using a theoretical-didactic and hands-on model. In addition, the group established the minimum requirements for attending and passing each MSKUS course level, the ideal number of course participants per instructor (4 participants/instructor), and the specific topics and musculoskeletal pathologies to be covered. In the same manner, the group concluded that 60% to 70% of course time should be focused on hands-on sessions. CONCLUSION: A multinational group of MSKUS sonographers using a consensus-based questionnaire (Delphi method) established the first recommendations and guidelines for MSKUS course training in the Americas. Pan-American League of Associations for Rheumatology urges that these guidelines and recommendations be adopted in the future by both national and regional institutions in the American continent involved in the training of Rheumatologists for the performance of MSKUS.

BACKGROUND: Mediastinal paragangliomas (PGs) are rare and particularly challenging neuroendocrine tumours. Clinical presentation is heterogeneous and tumour resection can be challenging due to bleeding and the risk of catecholamine surges in functional tumours. CASE SUMMARY: A 36-year-old man with multiple cardiovascular risk factors was admitted with subacute heart failure. Investigations revealed a large non-metastatic functional mediastinal PG irrigated mainly by a left circumflex coronary anomalous feeder branch. The surgical risk was deemed very high due to patient comorbidities, tumour vascularization, and close relation to major thoracic structures. A multidisciplinary team decided to perform embolization of the anomalous coronary branch followed by peptide-receptor radionuclide therapy with 177-LuDOTATE aiming to decrease tumour size and perioperative risk. Follow-up studies showed a reduction in tumour vascularization, size, and hormonal production. DISCUSSION: The innovative strategy of combining embolization of the anomalous feeder branch with radionuclide therapy proved to be a promising approach.
RESUMO
BACKGROUND: Right ventriculo-arterial coupling (RV-PA) can be estimated by echocardiography using the ratio between tricuspid annular plane systolic excursion (TAPSE) and pulmonary artery systolic pressure (PASP) and it has prognostic value in the general heart failure (HF) population. We aimed to study the clinical correlates and prognostic value of RV-PA in HF patients undergoing cardiac resynchronization therapy (CRT). METHODS: We retrospectively studied 70 HF patients undergoing CRT implantation. RESULTS: RV-PA coupling was estimated by TAPSE/PASP ratio using baseline echocardiography. Non-response to CRT was defined as improvement of left ventricular ejection fraction < 5% in a follow-up echo 6-12 months after CRT. Those with lower TAPSE/PASP ratios (worse RV-PA coupling) had higher NT-proBNP concentrations and increased E/e' ratio. TAPSE/PASP ratio and PASP, but not TAPSE, predicted nonresponse to CRT with TAPSE/PASP ratio showing the best discriminative ability with a sensitivity of 76% and specificity of 71%. Among these parameters, PASP independently predicted all-cause mortality. CONCLUSIONS: RV-PA coupling estimated by TAPSE/PASP ratio was associated with established prognostic markers in HF. It numerically outperformed PASP and TAPSE in predicting the response to CRT. Our data suggest that this simple and widely available echocardiographic parameter conveys significant pathophysiological and prognostic meaning in HF patients undergoing CRT.
RESUMO
AIM: Remote ischemic conditioning may reduce acute kidney injury (AKI) in patients undergoing a coronary intervention. As preinfarct angina (PIA) might act as a preconditioning stimulus in patients with ST-elevation myocardial infarction (STEMI), we aimed to study whether PIA reduces AKI in accordance to pre-existing chronic kidney disease. PATIENTS AND METHODS: We conducted a retrospective study including 891 consecutive STEMI patients who underwent primary coronary intervention from January 2008 to March 2016. AKI was determined on the basis of KDIGO criteria. The impact of PIA was evaluated in three groups according to the baseline glomerular filtration rate: less than 45 ml/min/1.73 m (group 1, n = 89), 45-59 ml/min/1.73 m (group 2, n = 117), and greater than or equal to 60 ml/min/1.73 m (group 3, n = 642). Univariate and multivariate predictors for AKI were determined. RESULTS: AKI developed in 13.8% of patients (n = 117) and was more prevalent in patients with worse baseline renal function (35% in group 1; 22% in group 2; and 9% in group 3, P < 0.01). The prevalence of PIA was similar across groups (28-34%, P = 0.2). Only in group 1 did patients with PIA have a significantly lower rate of AKI than patients without PIA (19 vs. 42%, P = 0.033). In multivariate analysis, the absence of PIA in group 1 patients conferred an almost three-fold risk of developing AKI (odds ratio = 2.92, P = 0.009), whereas no differences were found for the other groups. Age, total ischemic time, and intra-aortic balloon pump utilization were also related independently to AKI. CONCLUSION: In our series, STEMI patients with at least stage 3B chronic kidney disease had a three-fold risk of developing AKI in the absence of PIA. These findings suggest that patients with worse renal function may be more susceptible to the renoprotective effect of myocardial ischemic preconditioning.

BACKGROUND: Imbalance and disfuntion in regulatory T-cells (Tregs) and IL-17 producer lymphocytes (Th17) have been implicated in the pathogenesis of rheumatoid arthritis (RA). Gray scale synovial proliferation (GS), power Doppler signal (pD) and bone erosions seen on high resolution muskuloskeletal ultrasound (MSUS) are hallmarks of destructive articular disease. OBJECTIVE: To evaluate the association of peripheral Tregs and Th17 with MSUS findings in RA. METHODS: RA patients (1987 ACR criteria) treated with disease-modifying antirheumatic drugs (DMARDs) were included. Lymphocytes were isolated and immunophenotyped by flow cytometry to investigate regulatory FoxP3+ T cells and IL-17+ cells. MSUS (MyLab 60, Esaote, Genova, Italy, linear probe 6-18 MHz) was performed on hand joints, and a 10-joint US score was calculated for each patient. RESULTS: Data on lymphocytes subsets were avaiable for 90 patients. The majority of patients were Caucasian women with a median disease duration of 6 years (interquartile range: 2-13 years). Mean DAS28 was 4.28 (SD ± 1.64) and mean HAQ score was 1.11 (SD ± 0.83). There was no significant correlation of 10-joint GS score (rS = 0.122, 95% CI: - 0.124 to 0.336, P = 0.254) and 10-joint pD score (rS = 0.056, 95% CI: - 0.180 to 0.273, P = 0.602) with the mean percentage of peripheral Treg cells. Also, 10-joint GS score (rS = 0.083, 95% CI: - 0.125 to 0.302, P = 0.438) and 10-joint pD score 10 (rS = - 0.060, 95% CI: - 0.271 to 0.150, P = 0.575); did not correlate to Th17 profile. No association of bone erosions on MSUS with Treg and Th17 profiles (P = 0.831 and P = 0.632, respectively) was observed. CONCLUSION: In this first study addressing MSUS features and lymphocytes subtypes in established RA, data did not support an association of circulating Tregs and Th17 lymphocytes with inflammatory and structural damage findings on MSUS.

RESUMO
OBJECTIVES: To identify baseline predictors of remission and low disease activity (LDA) in early rheumatoid arthritis (RA) from the GLADAR (Grupo Latino Americano De estudio de la Artritis Reumatoide) cohort. METHODS: Patients with 1- and 2-year follow-up visits were included. Remission and LDA were defined by DAS28-ESR (< 2.6 and ≤ 3.2, respectively). Baseline predictors examined were gender, ethnicity, age at diagnosis, socioeconomic status, symptoms' duration, DMARDs, RF, thrombocytosis, anemia, morning stiffness, DAS28-ESR (and its components), HAQ-DI, DMARDs and corticosteroid use, and Sharp-VDH score. Multivariable binary logistic regression models (excluding DAS28-ESR components to avoid over adjustment) were derived using a backward selection method (α-level set at 0.05). RESULTS: Four hundred ninety-eight patients were included. Remission and LDA/remission were met by 19.3% and 32.5% at the 1-year visit, respectively. For the 280 patients followed for 2 years, these outcomes were met by 24.3% and 38.9%, respectively. Predictors of remission at 1 year were a lower DAS28-ESR (OR 1.17; CI 1.07-1.27; p = 0.001) and HAQ-DI (OR 1.48; CI 1.04-2.10; p = 0.028). At 2 years, only DAS28-ESR (OR 1.40; CI 1.17-1.6; p < 0.001) was a predictor. Predictors of LDA/remission at 1 year were DAS28-ESR (OR 1.42; CI 1.26-1.61; p < 0.001), non-use of corticosteroid (OR 1.74; CI 1.11-2.44; p = 0.008), and male gender (OR 1.77; CI 1.2-2.63; p = 0.036). A lower baseline DAS28-ESR (OR 1.45; CI 1.23-1.70; p < 0.001) was the only predictor of LDA/remission at 2 years. CONCLUSIONS: A lower disease activity consistently predicted remission and LDA/remission at 1 and 2 years of follow-up in early RA patients from the GLADAR cohort. Key Points ⢠In patients with early RA, a lower disease activity at first visit is a strong clinical predictor of achieving remission and LDA subsequently. ⢠Other clinical predictors of remission and LDA to keep in mind in these patients are male gender, non-use of corticosteroids and low disability at baseline. ⢠Not using corticosteroids at first visit is associated with a lower disease activity and predicts LDA/remission at 1 year in these patients.

OBJECTIVE: Most reports on serious infections (SI) in rheumatoid arthritis (RA) patients treated with biological disease-modifying antirheumatic drugs (bDMARDs) are from the USA and Western Europe. Data from other regions are largely missing. We report data from South American countries with different backgrounds and health-care systems but similar registries. METHODS: We merged 2010-2016 data from two registries, BIOBADABRASIL (Brazil) and BIOBADASAR (Argentina), which share the same protocol, online platform and data monitoring process. Patients with active RA were included when they began the first bDMARD or a conventional synthetic DMARD (csDMARD, control group). The SI incidence rate (IR) per 1000 patient/years and adjusted IR ratio (aIRR) were estimated for bDMARDs and csDMARDs. RESULTS: Data were analysed for 3717 RA patients with an exposure of 13,380 patient/years. The 2591 patients treated with bDMARDs (64% tumour necrosis factor-α inhibitors (TNFi)) had a follow-up of 9300 years, and the 1126 treated with csDMARDs had an exposure of 4081 patient/years. The SI IR was 30.54 (CI 27.18-34.30) for all bDMARDs and 5.15 (CI 3.36-7.89) for csDMARDs. The aIRR between the two groups was 2.03 ([1.05, 3.9] p = 0.034) for the first 6 months of treatment but subsequently increased to 8.26 ([4.32, 15.76] p < 0.001). The SI IR for bDMARDs decreased over time in both registries, dropping from 36.59 (28.41-47.12) in 2012 to 7.27 (4.79-11.05) in 2016. CONCLUSION: While SI remains a major concern in South American patients with RA treated with bDMARDs, a favourable trend toward a reduction was observed in the last years.Key Points⢠New comprehensive data on biologic drugs safety from international collaboration in South America.⢠First proposal for national registries data merging in South America.⢠Serious infections remain a major concern in RA patients treated with biologics.⢠A significant reduction of serious infections in RA patients exposed to biologics was observed over a 7 years period.

We present a case of a 63-year-old patient referred to a cardiology consultation due to progressive symptoms of heart failure. He had a history of an inferior ST elevation acute myocardial infarction 6 years ago. Echocardiogram revealed a giant left ventricular aneurysm/pseudoaneurysm involving the inferior and inferolateral left ventricular walls, with a massive mural thrombus. Additional characterization was done by cardiac magnetic resonance, essential in establishing the diagnosis of pseudoaneurysm and to guide subsequent management. In this case, we discuss the differential diagnosis between aneurysm and pseudoaneurysm and highlight the role of non-invasive multimodality imaging.

RESUMO
High-resolution musculoskeletal ultrasound (MSUS) has been increasingly employed in daily rheumatological practice and in clinical research. In rheumatoid arthritis (RA), MSUS can be now considered a complement to physical examination. This method evaluates synovitis through gray-scale and power Doppler and it is also able to identify bone erosions. The utilization of MSUS as a marker of RA activity has received attention in recent literature. Current data account for good correlation of MSUS with classical measures of clinical activity; in some instances, MSUS appears to perform even better. Diagnosis of subclinical synovitis by MSUS might help the physician in RA management. With some variation, interobserver MSUS agreement seems excellent for erosion and good for synovitis. However, lack of MSUS score standardization is still an unmet need. In this review, we describe several MSUS scores, as well as their correlation with clinical RA activity and response to therapy. Finally, we look at the relationship of MSUS with synovial tissue inflammation and discuss future perspectives for a better interpretation and integration of this imaging method into clinical practice.
