Introduction Rheumatoid arthritis (RA) is a well-documented independent risk factor for cardiovascular disease. Obesity may provide an additional link between inflammation and accelerated atherosclerosis in RA. Objective To evaluate the association between obesity and disease parameters and cardiovascular risk factors in RA patients. Method Cross-sectional study of a cohort of RA patients from three Brazilian teaching hospitals. Information on demographics, clinical parameters and the presence of cardiovascular risk factors was collected. Blood pressure, weight, height and waist circumference (WC) were measured during the first consultation. Laboratory data were retrieved from medical records. Obesity was defined according to the NCEP/ATPIII and IDF guidelines. The prevalence of obesity was determined cross-sectionally. Disease activity was evaluated using the DAS28 system (remission < 2.6; low 2.6–3.1; moderate 3.2–5.0; high > 5.1). Results The sample consisted of 791 RA patients aged 54.7 ± 12.0 years, of whom 86.9% were women and 59.9% were Caucasian. The mean disease duration was 12.8 ± 8.9 years. Three quarters were rheumatoid factor-positive, the mean body mass index (BMI) was 27.1 ± 4.9, and the mean WC was 93.5 ± 12.5 cm. The observed risk factors included dyslipidemia (34.3%), type-2 diabetes (15%), hypertension (49.2%) and family history of premature cardiovascular disease (16.5%). BMI-defined obesity was highly prevalent (26.9%) and associated with age, hypertension and dyslipidemia. Increased WC was associated with diabetes, hypertension, dyslipidemia and disease activity. Conclusion: Obesity was highly prevalent in RA patients and associated with disease activity.

In view of the method of diagnosing sarcopenia being complex and considered to be difficult to introduce into routine practice, the European Working Group on Sarcopenia in Older People (EWGSOP) recommends the use of the SARC-F questionnaire as a way to introduce assessment and treatment of sarcopenia into clinical practice. Only recently, some studies have turned their attention to the presence of sarcopenia in systemic sclerosis (SSc).There is no data about performance of SARC-F and other screening tests for sarcopenia in this population. To compare the accuracy of SARC-F, SARC-CalF, SARC-F+EBM, and Ishii test as screening tools for sarcopenia in patients with SSc. Cross-sectional study of 94 patients with SSc assessed by clinical and physical evaluation. Sarcopenia was defined according to the revised 2019 EWGSOP diagnostic criteria (EWGSOP2) with assessments of dual-energy X-ray absorptiometry, handgrip strength, and short physical performance battery (SPPB). As case finding tools, SARC-F, SARC-CalF, SARC-F+EBM and Ishii test were applied, including data on calf circumference, body mass index, limitations in strength, walking ability, rising from a chair, stair climbing, and self reported number of falls in the last year. The screening tests were evaluated through receiver operating characteristic (ROC) curves. Standard measures of diagnostic accuracy were computed using the EWGSOP2 criteria as the gold standard for diagnosis of sarcopenia. Sarcopenia was identified in 15 (15.9%) patients with SSc by the EWGSOP2 criteria. Area under the ROC curve of SARC-F screening for sarcopenia was 0.588 (95% confidence interval (CI) 0.420-0.756, p = 0.283). The results of sensitivity, specificity, positive likelihood ratio (+LR), negative likelihood ratio (-LR) and diagnostic Odds Ratio (DOR) with the EWGSOP2 criteria as the gold standard were 40.0% (95% CI, 19.8-64.2), 81.0% (95% CI, 71.0-88.1), 2.11 (95% CI, 0.98-4.55), 0.74 (95% CI, 0.48-1.13) and 2.84 (95% CI, 0.88-9.22), respectively. SARC-CalF and SARC-F+EBM showed better sensitivity (53.3%, 95% CI 30.1-75.2 and 60.0%, 95% CI 35.7-80.2, respectively) and specificity (84.8%, 95% CI 75.3-91.1 and 86.1%, 95% CI 76.8-92.0, respectively) compared with SARC-F. The best sensitivity was obtained with the Ishii test (86.7%, 95% CI 62.1-96.3), at the expense of a small loss of specificity (73.4%, 95% CI 62.7-81.9). Comparing the ROC curves, SARC-F performed worse than SARC-CalF, SARC-F+EBM and Ishii test as a sarcopenia screening tool in this population (AUCs 0.588 vs. 0.718, 0.832, and 0.862, respectively). Direct comparisons between tests revealed differences only between SARC-F and Ishii test for sensitivity (p = 0.013) and AUC (p = 0.031). SARC-CalF, SARC-F+EBM, and Ishii test performed better than SARC-F alone as screening tools for sarcopenia in patients with SSc. Considering diagnostic accuracy and feasibility aspects, SARC-F+EBM seems to be the most suitable screening tool to be adopted in routine care of patients with SSc.

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.

IntroductionThe 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.MethodsA 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.ResultsWe 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.ConclusionThe 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 Vascular cell adhesion molecule-1 (VCAM-1) is involved in the progression of glomerular and tubulointerstitial injury in lupus nephritis (LN) and can be easily assessed in urine. The aim of this study was to assess urinary soluble VCAM-1 (uVCAM-1) as a biomarker of disease activity and treatment response in LN. Methods This prospective study enrolled 62 patients with class III, IV or V LN diagnosed within the last 3 years and divided them in two groups: with and without active nephritis at the inclusion, each group with 31 patients. At each visit, a urine sample was collected for uVCAM-1 evaluation and the nephritis status was assessed. Results Median uVCAM-1 level was elevated in patients with active compared to inactive LN ( P  < 0.001). The ROC curve of uVCAM-1 demonstrated an AUC of 0.84 and a cutoff of 47.2 ng/mgCr yielded a good sensitivity (74.2%) and specificity (74.2%) for the diagnosis of active LN. A significant correlation was found between uVCAM-1 level and renal activity scores and traditional biomarkers of LN. The level of uVCAM-1 dropped in patients with active LN who went into remission ( P  < 0.001), increased in patients who went into activity ( P  = 0.002) and did not change in patients who remained inactive ( P  = 0.797). The level of uVCAM-1 peaked during the flare of LN ( P  < 0.05). Conclusion The uVCAM-1 is a reliable biomarker that reflects renal disease activity and is useful for monitoring individual patients with lupus nephritis over time.

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 treat-to-target strategy (T2T) was associated with better outcomes in psoriatic arthritis (PsA) compared to standard care in clinical trials. This study aimed to analyze factors precluding treatment optimization in a T2T strategy conducted in a real-world cohort of PsA patients. A retrospective cross-sectional study nested in a cohort was conducted. Medical records of patients ≥ 18 years old, fulfilling CASPAR criteria and with at least one visit in the PsA clinic, were reviewed. Demographic data, current medication, and minimal disease activity (MDA) criteria were recorded. Reasons for the non-escalation of therapy in patients who were not classified as MDA were reported as absolute and relative frequencies. In the 8-month period, 131 visits (corresponding to 74 patients) were conducted. The MDA criteria were available in 113 visits (86.3%) and patients were classified as MDA in 31.0% of the visits (N = 35/113). Although in 69.0% of the visits patients were not in MDA, (N = 78/113), therapy was adjusted in only 42.3% (N = 33/78). Reasons precluding treatment escalation in non-MDA subjects were physician’s impression of remission (57.7%, N = 26), non-adherence to previous prescription (17.8%, N = 8), restricted access to drugs (17.8%, N = 8), adverse events (11.1%, N = 5), poor understanding of medication instructions (6.7%, N = 3), patient’s refusal to escalate therapy (4.4%, N = 2), and recent change in therapy (2.2%, N = 1). Discordance between the physician’s clinical evaluation and the MDA criteria, non-adherence to prescription, and poor access to drugs were the main factors precluding escalation of therapy in a T2T strategy in a real-world PsA cohort.

Background: To prospectively evaluate the safety and clinical impact of SARS-CoV-2 vaccines in patients with systemic lupus erythematosus (SLE). Methods: Subanalysis of the Brazilian multicenter observational study “Safety, Effectiveness and Duration of Immunity after Vaccination against SARS-CoV-2 in Patients with Immune-Mediated Inflammatory Diseases (SAFER)”, which included SLE patients vaccinated with CoronaVac, ChAdOx1, or BNT162b2. Patients with HIV infection, pregnant women, or those with immunosuppression not related to SLE were excluded. Safety data related to adverse events and underlying disease activity were assessed. Additionally, COVID-19 cases were monitored throughout the follow-up period. Results: The study included 373 patients with systemic lupus erythematosus (SLE), with a mean age of 36 years, the majority being women (89.8%). The most common adverse events after SARS-CoV-2 vaccination were injection site reactions and headache, observed both after the first and subsequent doses. The ChAdOx-1 vaccine was associated with a higher frequency of adverse events compared to CoronaVac. At baseline, 38.3% of patients were in remission, 32.8% had low disease activity, and 28.9% had moderate to high activity. Following CoronaVac vaccination, there was an increase in remission rates (from 34.6% to 51.1%) and a significant reduction in moderate to high activity (from 37.6% to 15.0%) after the first dose, with this reduction partially maintained after the second dose. In contrast, patients vaccinated with ChAdOx-1 showed an increase in moderate to high activity (from 14.5% to 38.2% after the first dose), a trend that persisted after the second dose. No statistically significant changes in disease activity were observed among those who received BNT162b2. During follow-up, 44 cases of COVID-19 were reported, all mild, with no deaths or need for intensive care unit admission. Conclusions: Vaccination against SARS-CoV-2 demonstrated a favorable safety profile in patients with SLE, with a low frequency of serious adverse events. While analysis of disease activity revealed variations across vaccine platforms, most notably an increased proportion of moderate to high disease activity among those receiving ChAdOx-1 compared with CoronaVac and BNT162b2, the overall occurrence of COVID-19 during follow-up was limited to mild cases, with no severe outcomes. These findings highlight that, despite potential risks of disease exacerbation, the clear protection against severe COVID-19 supports vaccination as a beneficial strategy for this immunocompromised population.

Background Rheumatoid arthritis (RA) is a systemic autoimmune disease with articular and extra-articular manifestations. Chronic inflammation may contribute to sarcopenia independently of age. While cross-sectional studies report sarcopenia in 24–30% of RA patients, longitudinal data remain limited. This study aimed to assess long-term changes in sarcopenia and body composition in RA patients and explore their associations with clinical features and health outcomes. Methods In this prospective cohort study, 90 RA patients were followed for a median of 6.4 years (IQR: 5.8–7.0). Clinical features, falls, fragility fractures, and mortality were recorded. Body composition (BMI, appendicular lean mass index [ALMI], fat mass index [FMI]) was assessed using dual-energy X-ray absorptiometry; grip strength by JAMAR dynamometer; and physical performance by the Timed Up and Go test. Sarcopenia was defined using EWGSOP2 criteria. Statistical analyses included ANOVA, Kruskal–Wallis, chi-squared tests, generalized estimating equations, Kaplan–Meier curves, and regression models. Results At baseline, mean age was 56.5 ± 7.3 years, median disease duration 8.5 years (IQR:3.0–18.0), median DAS28-CRP 3.0 (IQR:1.0–3.0), and mean HAQ-DI 1.1 ± 0.9. Seven patients (7.7%) had sarcopenia, including one severe case. Most participants were overweight with elevated FMI. Sarcopenia prevalence and clinical characteristics remained stable, with no new sarcopenia cases during follow-up. ALMI increases were associated with FMI increases ( p  = 0.005). Baseline sarcopenia was not associated with falls, fractures, or mortality. Low muscle mass and poor physical performance were not linked to mortality, but low muscle strength showed a trend toward higher mortality risk (HR = 4.35, 95% CI: 0.51–37.25). After adjusting for age, disease duration, glucocorticoid dose, and DMARD use, low muscle strength was significantly associated with falls (B = 3.92,95% CI:1.03–15.02; p  = 0.046). No associations were found for low muscle mass, low physical performance, or sarcopenia with these outcomes. Conclusion In RA patients receiving regular care, sarcopenia prevalence remained high and stable. Low muscle strength was associated with falls and showed a trend toward increased mortality risk, possibly due to limited sample size, highlighting its potential prognostic value. However, the absence of a control group limits interpretation, as observed changes may reflect normal aging rather than disease-specific effects. Clinical trial number Not applicable.

ObjectivesTo evaluate the disease activity before and after COVID-19 and risk factors associated with outcomes, including hospitalization, intensive care unit (ICU) admission, mechanical ventilation (MV) and death in patients with spondylarthritis (SpA).MethodsReumaCoV Brazil is a multicenter prospective cohort of immune-mediated rheumatic diseases (IMRD) patients with COVID-19 (case group), compared to a control group of IMRD patients without COVID-19. SpA patients enrolled were grouped as axial SpA (axSpA), psoriatic arthritis (PsA) and enteropathic arthritis, according to usual classification criteria.Results353 SpA patients were included, of whom 229 (64.9%) were axSpA, 118 (33.4%) PsA and 6 enteropathic arthritis (1.7%). No significant difference was observed in disease activity before the study inclusion comparing cases and controls, as well no worsening of disease activity after COVID-19. The risk factors associated with hospitalization were age over 60 years (OR = 3.71; 95% CI 1.62–8.47, p = 0.001); one or more comorbidities (OR = 2.28; 95% CI 1.02–5.08, p = 0.001) and leflunomide treatment (OR = 4.46; 95% CI 1.33–24.9, p = 0.008). Not having comorbidities (OR = 0.11; 95% CI 0.02–0.50, p = 0.001) played a protective role for hospitalization. In multivariate analysis, leflunomide treatment (OR = 8.69; CI = 95% 1.41–53.64; p = 0.023) was associated with hospitalization; teleconsultation (OR = 0.14; CI = 95% 0.03–0.71; p = 0.01) and no comorbidities (OR = 0.14; CI = 95% 0.02–0.76; p = 0.02) remained at final model as protective factor.ConclusionsOur results showed no association between pre-COVID disease activity or that SARS-CoV-2 infection could trigger disease activity in patients with SpA. Teleconsultation and no comorbidities were associated with a lower hospitalization risk. Leflunomide remained significantly associated with higher risk of hospitalization after multiple adjustments.
