Objective: This study aimed to assess the effectiveness of the Global OMERACT-EULAR Synovitis Score (GLOESS) of bilateral second to fifth metacarpophalangeal joints (MCP 2-5) in evaluating rheumatoid arthritis (RA) activity in a real-life setting., Methods: This cross-sectional study included consecutive RA patients without hyperalgesia. Clinical data were extracted from electronic medical records. Evaluations were conducted on bilateral MCP 2-5 by two independent experts in musculoskeletal ultrasound (MSUS). Correlation between clinical and ultrasonographic parameters was analyzed, aiming to define a cutoff value for detecting disease activity., Results: Sixty-nine patients were included. The mean DAS28-ESR was 4.3 (±1.4), and the median GLOESS was 7 (13). The correlation between GLOESS and DAS28 was moderate (r = .62; P < .05). A total GLOESS score of ≤3 and all joints with both GS and PD ≤1 showed good sensitivity and specificity for detecting disease activity (remission/low vs moderate/high, P = 0)., Conclusion: In a real-life scenario, GLOESS for MCP 2-5 emerges as a valuable measure of RA activity. The optimal cutoff distinguishing remission/low from moderate/high disease activity was determined to be GLOESS ≤3, with all MCP joints exhibiting both GS and PD scores of ≤1., (© 2024 American Institute of Ultrasound in Medicine.)

Background: Nail psoriasis occurs frequently in patients with psoriatic disease, it can lead to functional impairment, pain, discomfort, decreased quality of life and can also be a predictor for the development of arthritis. Early recognition of this condition can provide early and effective treatment and prevent structural impairment. This study aims to identify nail ultrasonographic characteristics in three groups: psoriasis (PsO), psoriatic arthritis (PsA) and controls patients, to determine if the ultrasonography (US) can identify early signs of nail psoriatic impairment or local inflammation. We conducted nail US to determine nail matrix resistance index (NMRI), nail bed resistance index (NBRI), and power Doppler (PD) and grayscale (GS) parameters in these 3 groups., Methods: Single-center, cross-sectional study. GS, PD, and spectral doppler images of bilateral 2nd and 3rd fingernails were acquired from 35 PsO, 31 PsA, and 35 controls patients. An US equipment with an 18 MHz linear transducer for GS and 8.0 MHz for PD was used. PD, NMRI, NBRI, nail plate thickness (NPT), nail bed thickness (NBT), nail matrix thickness (NMT), and morphostructural characteristics of the trilaminar structure (TS) were evaluated in saved images, blind., Results: Mean NMRI and NBRI did not differ between groups. Linear regression analysis detected no relationships between PsO or PsA and NMRI or NBRI. Nail PD grade did not differ between groups. Type I and IV TS changes were more frequent in PsO; types II and III changes were more frequent in PsA (p < 0.001). NPT was greater in PsA and PsO groups than controls: PsA 0.73 ± 0.14 mm, PsO 0.72 ± 0.15 mm, Controls 0.67 ± 0.10 mm (p = 0.001)., Conclusion: Echographic TS characteristics of the nail plate and NPT evaluated by GS are useful and can distinguish PsO and PsA nails from controls. NMRI, NBRI, and US nail microcirculation parameters could not distinguish psoriatic nails., Trial Registration: 72762317.4.0000.5327 (Certificate of Presentation of Ethical Appreciation - CAAE - Plataforma Brasil) Avaiable in  https://plataformabrasil.saude.gov.br/login.jsf ., (© 2021.

Introduction: The TNF inhibitors were the first immunobiologicals used to treat rheumatic diseases, but their use is associated with an increased risk of tuberculosis. The primary objective is to estimate the incidence of tuberculosis in patients with rheumatic diseases exposed to anti-TNF therapy. The secondary objectives are to evaluate the incidence of tuberculosis by region and subgroups of diseases, to review the presentation of tuberculosis in these patients, and to assess the time elapsed between onset of anti-TNF therapy and development of active granulomatous disease., Methods: A systematic review of the literature was conducted in MEDLINE, the Cochrane Library, and LILACS. The primary endpoint was described as incidence and secondary outcomes, through subgroup analyses and comparisons of means., Results: We included 52 observational studies. Among the exposed patients, 947 cases of tuberculosis were documented (62.2% pulmonary), with a cumulative incidence of 9.62 cases per 1000 patients exposed. TB incidence across different continents was distributed as follows: South America, 11.75 cases/1000 patients exposed; North America, 4.34 cases/1000 patients exposed; Europe, 6.28 cases/1000 patients exposed; and Asia, 13.47 cases/1000 patients exposed. There were no significant differences in TB incidence among the described diseases. The mean time elapsed from start of anti-TNF therapy until the endpoint was 18.05 months., Conclusion: The incidence of TB in patients with rheumatic diseases exposed TNF inhibitor considering all countries was 9.62 cases per 1000 patients exposed. TB incidence was higher in South America and Asia compared with North America and Europe. Most cases occurred in the first XX months of use, and the pulmonary form predominated.Key Points• Higher incidence of tuberculosis in patients exposed to anti-TNF compared with the general population.• Higher incidence of TB in countries of South America and Asia compared with North America and Europe.

Introduction: Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis. The advent of immunobiologic therapy with TNF inhibitors agents, has been associated with a significant increase in incident cases of tuberculosis in this population., Objective: To estimate the incidence of tuberculosis in patients receiving TNF inhibitors therapy for rheumatic diseases. As secondary objectives, we sought to evaluate mortality and the clinical impact of screening for latent tuberculosis infection., Methods: This retrospective study included patients with rheumatic diseases of Public Health System from the Brazilian state, a high TB incidence area, who received prescriptions of TNF inhibitors agents between 2006 and 2016., Results: A total of 5853 rheumatic disease patients were included. Patients were predominantly women (68.7%) aged 49.5 (± 14.7) years old. Forty-three cases of TB were found (2.86 cases per 1000 person-years; 18 times higher than in the general population). Adalimumab and certolizumab users presented a higher risk for TB development compared to etanercept users (RR: 3.11, 95%CI 1.16-8.35; 7.47, 95%CI 1.39-40.0, respectively). In a subgroup of patients, screening for latent tuberculosis infection was performed in 86% of patients, and 30.2% had a positive tuberculin skin test. Despite latent TB treatment, TB was diagnosed in 2 out of 74 (2.7%) patients. Overall, TB diagnosis did not increase mortality., Conclusion: In this population-based study of rheumatic disease patients from a high incident area, TNF inhibitor exposure was associated with an 18-time increased TB incidence. Adalimumab and certolizumab were associated with greater and earlier TB diagnosis compared to etanercept., Competing Interests: The authors have declared that no competing interests exist.

Background: In psoriatic arthritis (PsA) almost all qualitative studies have been performed in European populations. This work aimed to evaluate the impact of PsA in Brazilian and French subjects, as well as to explore cultural differences in the experience of disease and to recognize domains important for patients living with PsA outside Europe., Methods: A qualitative study was conducted in two university hospitals in Brazil and France; outpatients fulfilling Classification Criteria for PsA participated in individual interviews regarding the impact of PsA; interviews were conducted in the local language. The sample size was defined by saturation; interviews were recorded and transcribed and content analysis was performed., Results: Fifteen patients were interviewed in Brazil and 13 in France. Mean disease duration was 16.5 ± 12.5 years (range: 8 months to 47 years) and 14.4 ± 8.4 years (range 12 months to 29 years) for Brazilian and French subjects, respectively. A broad impact was perceived: 67 codes emerged from the interviews and were grouped in 41 categories. Although 2/3 of categories were common to both nationalities, some important health domains from the perspective of PsA patients from a non-European background were brought to light including sexual dysfunction, emotional impact of psoriasis and impact of prejudice on social and professional life., Conclusions: This study highlights the importance of assessing the impact of PsA on a national level, emphasizing the common cross-cultural aspects but also revealing domains of interest for patients with PsA living outside Europe which merit further study.

Introduction: The Mean Platelet Volume (MPV) is a platelet activation biomarker that has been recently correlated with disease activity in SLE. We aimed to evaluate the MPV in patients with SLE comparing it with healthy individuals, to study the correlation between MPV and SLE Disease Activity Index (SLEDAI) in SLE patients and to analyze possible correlation between MPV and Erythrocyte Sedimentation Rate (ESR), C-Reactive Protein (CRP), and complement components C3 and C4., Methods: This is a cross-sectional study in which 81 patients with SLE according to the American College of Rheumatology (ACR) diagnostic classification criteria and 58 healthy controls were included. Active disease was defined as SLEDAI>0., Results: Patients with active SLE had decreased MPV when compared to inactive disease group (10.0±0.7fL vs . 10.7±1.0fL, p =0.005, respectively) and when compared to control group (10.9±1.0fL, p <0.001). Our study found a weak negative correlation between the SLEDAI and the MPV (r=-0.29, p =0.009). There was no correlation between MPV and CRP, ESR, C3 and C4. Also, no correlation between SLEDAI and CRP, ESR, C3 and C4 was found., Conclusion: MPV decreases in patients with active SLE and is inversely correlated with SLEDAI.

Objective: To assess the main fears and beliefs of people with rheumatoid arthritis (RA) and their effect on treatment outcomes; METHODS: A systematic literature review was conducted in Pubmed/Medline; original articles published up to May 2017, reporting fears and/or beliefs of adult patients with RA were analyzed. Fears and beliefs were collected by two independent researchers and grouped into categories., Results: Among 474 references identified, 84 were analyzed, corresponding to 24,336 RA patients. Fears were reported in 38.4% of the articles (N = 32/84): most studies described fears related to pharmacological therapy (50.0%, N = 16/32) and fear of disability (28.1%, N = 9/32). Beliefs were reported in 88.0% of articles (N = 74/84) and were found to moderate the patient-perceived impact of RA in 44.6% (N = 33/74), mainly the emotional impact (18.9%, N = 14/74); measures of function, quality of life, fatigue and pain were also found to be affected by patients' beliefs in 8.1% (N = 6/74), 6.8% (N = 5/74), 2.7% (N = 2/74) and 2.7% (N = 2/74) of the articles, respectively. Beliefs about therapy were linked to adherence in 17.6% of articles (N = 13/74) and beliefs about cause of RA predicted coping patterns in 12.2% of publications (N = 9/74). Only 9.5% (N = 8/84) of articles reported fears and/or beliefs of patients living outside Europe and North America: there was only one work which recruited patients in Latin America and no article included patients from Africa., Conclusion: In RA, patients' beliefs are linked to impact of disease and non-adherence. Further research is needed on fears/ beliefs of patients living outside Europe and North America.

Introduction: Interstitial lung disease (ILD) is currently the primary cause of death in systemic sclerosis (SSc). Thoracic high-resolution computed tomography (HRCT) is considered the gold standard for diagnosis. Recent studies have proposed several clinical algorithms to predict the diagnosis and prognosis of SSc-ILD., Objective: To test the clinical algorithms to predict the presence and prognosis of SSc-ILD and to evaluate the association of extent of ILD with mortality in a cohort of SSc patients., Methods: Retrospective cohort study, including 177 SSc patients assessed by clinical evaluation, laboratory tests, pulmonary function tests, and HRCT. Three clinical algorithms, combining lung auscultation, chest radiography, and percentage predicted forced vital capacity (FVC), were applied for the diagnosis of different extents of ILD on HRCT. Univariate and multivariate Cox proportional models were used to analyze the association of algorithms and the extent of ILD on HRCT with the risk of death using hazard ratios (HR)., Results: The prevalence of ILD on HRCT was 57.1% and 79 patients died (44.6%) in a median follow-up of 11.1 years. For identification of ILD with extent ≥10% and ≥20% on HRCT, all algorithms presented a high sensitivity (>89%) and a very low negative likelihood ratio (<0.16). For prognosis, survival was decreased for all algorithms, especially the algorithm C (HR = 3.47, 95% CI: 1.62-7.42), which identified the presence of ILD based on crackles on lung auscultation, findings on chest X-ray, or FVC <80%. Extensive disease as proposed by Goh et al. (extent of ILD > 20% on HRCT or, in indeterminate cases, FVC < 70%) had a significantly higher risk of death (HR = 3.42, 95% CI: 2.12-5.52). Survival was not different between patients with extent of 10% or 20% of ILD on HRCT, and analysis of 10-year mortality suggested that a threshold of 10% may also have a good predictive value for mortality. However, there is no clear cutoff above which mortality is sharply increased., Conclusion: Clinical algorithms had a good diagnostic performance for extents of SSc-ILD on HRCT with clinical and prognostic relevance (≥10% and ≥20%), and were also strongly related to mortality. Non-HRCT-based algorithms could be useful when HRCT is not available. This is the first study to replicate the prognostic algorithm proposed by Goh et al. in a developing country., (Copyright © 2017 Elsevier Inc. All rights reserved.)

To examine disease activity and physical function after implementation of treat-to-target (T2T) strategy in patients with established rheumatoid arthritis (RA) over a long-term period. Patients with RA were started on a T2T strategy in 2005 and followed through 2014. Patients were seen every 3-4 months until remission/low disease activity was achieved and every 6 months thereafter. Disease activity was measured by the DAS28 and CDAI, and physical function by the HAQ-DI. Results were presented as all observed data, without imputation for missing values. Changes in disease activity and physical function were evaluated by generalized estimating equations (GEE). Two hundred and twenty-nine patients were included, with a mean (SD) disease duration of 10.6 (7.4) years. Significant improvements were seen in both composite scores during the follow-up period, as demonstrated by DAS28 (β coefficient = 0.19; 95% CI = 0.16-0.21; p < 0.01) and by CDAI (β coefficient = 1.59; 95% CI = 1.84-1.34; p < 0.01). Physical function also improved, as demonstrated by HAQ-DI (β coefficient = 0.03; 95% CI = 0.02-0.04; p < 0.01). Biological therapy was associated with improvement in disease activity and in physical function. Leflunomide was only associated with improvement in physical function. Clinically meaningful reductions of DAS28, CDAI and HAQ-DI were observed in patients with established rheumatoid arthritis from 2005 to 2014. Implementation of new therapeutic options, in the scenario of T2T strategy, was associated with improvement in disease activity and physical function.

The present study aims to evaluate differences in clinical and laboratory manifestations and medication use in the different ages of disease onset in patients with systemic lupus erythematosus (SLE). This cross-sectional study consisted of 598 SLE patients (550 female and 48 male), who attended the Rheumatology Clinic of the Hospital de Clínicas de Porto Alegre between 2003 and 2015. Demographic, clinical and laboratory data were collected. The patients were classified into three groups according to their ages at disease diagnosis. Mean age of diagnosis was 33.6 ± 14.3 years, and the median (25th-75th percentile) disease duration was 13 (7-20) years. Among the patients studied, 419 (70%) were adult-onset (aSLE), 90 (14.8%) were late-onset (lSLE) and 89 (14.8%) were childhood-onset (cSLE). The female to male ratio was higher in aSLE (18:1) compared to the other groups (p = 0.001). Arthritis was predominantly found in aSLE (78.5%) when compared with lSLE (57.7%) (p < 0.001). Nephritis was more common in cSLE (60.6%) than in lSLE (26.6%) (p < 0.001). Median (25th-75th percentile) of SLE disease activity index (SLEDAI) was higher in the cSLE group [2 (0-5)] when compared to the lSLE group [0 (0-4)] (p = 0.045). Childhood-onset SLE showed a more severe disease due to the higher incidence of nephritis and needed a more aggressive treatment with immunosuppressive drugs.

Objectives: Our goal is to study the correlations among gray-scale seven-joint ultrasound score (GS-US7), power Doppler seven-joint ultrasound score (PD-US7), disease activity score-28 joints (DAS28), simplified disease activity index (SDAI) and clinical disease activity index (CDAI) in patients with and without fibromyalgia (FM)., Methods: A matched case-control study included all patients consecutively seen in the Rheumatoid Arthritis (RA) Clinic. Participants were allocated into one of two groups: RA with FM and RA without FM. Ultrasound (US) and clinical scoring were blinded for the presence of FM. Medians and proportions were compared by Mann-Whitney's test and McNemar's test, respectively. Spearman's rank correlation coefficients (rs) were calculated among clinical and US scores and differences were tested by r-to-z transformation test., Results: Seventy-two women were included, out of 247 RA patients, mostly white, with median (IQR) age of 57.5 (49.3-66.8) years, with RA symptoms for 13.0 (6.0-19.0) years and FM symptoms for 6.0 (2.0-15.0) years. Disease-modifying antirheumatic drugs, non-steroidal anti-inflammatory drugs and prednisone use was comparable between groups. Objective activity parameters were not different between groups. RA patients with FM had greater DAS28, SDAI and CDAI but similar GS-US7 and PD-US7. GS-US7 correlated with DAS28, SDAI and CDAI in patients with and without FM (rs = 0.36-0.57), while PD-US7 correlated with clinical scores only in patients without FM (rs = 0.35-0.38)., Conclusion: To our knowledge, this is the first study to demonstrate that ultrasound synovitis scores are not affected by FM in RA patients. PD-US7 performed better than GS-US7 in long-standing RA patients with DAS28, SDAI or CDAI allegedly overestimated due to FM. Since sonographic synovitis predicts erosion better than swollen joint count, C-reactive protein and erythrocyte sedimentation rate, US should be considered a promising treatment target in RA patients with FM.

Systemic lupus erythematosus (SLE) is a systemic inflammatory disease associated with genetic, environmental, hormonal, and immunological factors. One of these factors is vitamin D deficiency. Vitamin D plays many roles in the immune system. Several studies have suggested a potential role in the development of autoimmune diseases. SLE patients have low serum levels of vitamin D, which increase the possibility of an association between vitamin deficiency and disease onset and evolution. This review of the literature presents an analysis of the aspects related to the immunoregulatory effects of vitamin D and its importance for SLE, as well as the recommendations for vitamin D supplementation in these patients.
