Autoimmune/autoinflammatory syndrome induced by adjuvants (ASIA) was first described in 2011 to cover disorders characterized by dysregulation of the immune system after exposure to an adjuvant. In the present review, the authors focus on silicone-induced ASIA. In the last two decades, there has been worldwide increase in the use of silicone breast implant (SBI) as an aesthetic procedure, raising concerns for possible effects on the immune system, especially in people who already have previous immune dysregulation. The authors did a critical review of the most important articles referring to silicone-induced ASIA, including most recent studies regarding physiopathologic mechanism. Despite large-scale epidemiological studies conducted to assess the association between SBI and autoimmune/rheumatic disorders, the results remain inconclusive, and the debate over the safety of SBIs remains heated. The explantation of silicone breast has been indicated for silicone-induced ASIA with improvement of unspecific symptoms in the majority of patients; however, the outcome seems different in patients with definitive autoimmune rheumatic disease (AIRD). There is no prospective study evaluating the risk of flares after SBI in patients who already have an AIRD. Therefore, based on the literature, we cannot contraindicate the procedure; however, we need to advertise about the risk of ASIA to the patients with AIRD. Long-term safety and implant-related outcomes should be discussed with these patients, considering each case individually, assessing genetic and environmental factors, and determining if the autoimmune disease is in remission or not, for shared decision among patient and the physician.

Background Myostatin is a protein in the TGF-β family that negatively regulates muscle mass, and follistatin is a myostatin antagonist. Objective The aim of this study was to measure serum levels of myostatin and follistatin in idiopathic inflammatory myopathy patients and correlate these levels with muscle strength, fatigue, functional capacity, damage, and serum levels of muscle enzymes. Methods This was a multicenter cross-sectional study including 50 patients (34 dermatomyositis and 16 polymyositis [PM]) and 52 healthy individuals (control group [CG]). The disease status was evaluated according to the International Myositis Assessment & Clinical Studies. Fatigue was rated according to the Fatigue Severity Scale, and body composition was measured using dual-energy x-ray emission densitometry. Myostatin and follistatin were measured using enzyme-linked immunosorbent assays. Results Mean age was 50.9 ± 14.0 years, and mean disease duration was 89.2 ± 80.9 months. There were no differences in levels of myostatin (14.15 ± 9.65 vs. 10.97 ± 6.77 ng/mL; p = 0.131) or follistatin (0.53 ± 0.71 vs. 0.49 ± 0.60 ng/mL; p = 0.968) between patients and the CG. However, myostatin levels were higher in PM than CG (16.9 ± 12.1 vs. 11.0 ± 6.8 ng/mL; p = 0.036). There was no difference in serum myostatin among patients with and without low lean mass. Patients not treated with corticosteroids had higher serum levels of myostatin than the CG. There was a weak negative correlation between follistatin and Manual Muscle Testing and a Subset of Eight Muscles and a weak positive correlation between follistatin and Healthy Assessment Questionnaire. Conclusions Serum levels of myostatin and follistatin did not differ between dermatomyositis and PM patients and control subjects. The assessment of serum levels of myostatin and follistatin in idiopathic inflammatory myopathy patients seems not to be helpful in clinical practice.

Endothelial dysfunction and reduced number of endothelial progenitor cells (EPCs) in peripheral blood are contributing factors to cardiovascular disease in systemic lupus erythematosus (SLE) patients. Endothelial progenitor cell proliferation is regulated by vascular endothelial growth factor (VEGF). Angiotensin-converting enzyme inhibitors reduce cardiovascular mortality in patients with coronary heart disease.This was a randomized trial including 37 female SLE patients without cardiovascular risk factors allocated into 2 groups: 19 patients received ramipril 10 mg/d for 12 weeks (IG) and 18 patients maintained without ramipril (CG). Endothelial function was assessed by brachial artery ultrasound measuring flow-mediated dilation, and EPCs were quantified by flow cytometry and cell culture, at baseline and after 12 weeks. Serum VEGF levels were measured by enzyme-linked immunosorbent assay. Statistical analysis was intention to treat. p0.05 was considered significant.After 12 weeks, higher flow-mediated dilation (6.17% vs. 11.14%, p0.001) was observed in IG, without change in CG (5.37% vs. 5.02%, p = 0.630). Higher number of EPC colony-forming units was also observed in IG (21.3 ± 10.4 vs. 31.6 ± 8.5, p0.001), without difference in CG ( p = 0.714). No difference was found in EPCs evaluated by flow cytometry. Vascular endothelial growth factor level increased after 12 weeks in IG ( p = 0.048), with no difference in CG ( p = 0.661).Ramipril improved endothelial function and increased the numbers of EPCs evaluated by cell culture and VEGF levels in SLE patients without cardiovascular risk factors. These data suggest that angiotensin-converting enzyme inhibitor bring an extra benefit beyond the hypotensive action and should be considered as a preferred antihypertensive drug in SLE patients.

Background/objective The Latin American population living with lupus lacks reliable and culturally competent health education resources. We describe a Spanish and Portuguese online program to educate Latin American people about lupus. Methods An extensive network of Latin American stakeholders participated in the program design, implementation, dissemination, and evaluation. Patients and rheumatologists selected core topics. Rheumatologists prepared the content using evidence-based data. Adaptations were conducted to meet the audience's health literacy and cultural values. Social media was used to post audiovisual resources and facilitate users' interactions with peers and educators, and a Web site was created to offer in-depth knowledge. Results The most massive outreach was through Facebook, with more than 20 million people reached and 80,000 followers at 3 months, between the Spanish and Portuguese pages. Nearly 90% of followers were from Latin America. A high engagement and positive responses to a satisfaction survey indicate that Facebook users valued these resources. The Spanish and Portuguese Web sites accumulated more than 62,000 page views, and 71.7% of viewers were from Latin American. Conclusions The engagement of patients and stakeholders is critical to provide and disseminate reliable lupus education. Social media can be used to educate and facilitate interactions between people affected by lupus and qualified health care professionals. Social media-based health education has extensive and scalable outreach but is more taxing for the professional team than the Web site. However, the Web site is less likely to be used as a primary education source by Latin American people because they value social interactions when seeking lupus information.

The objective of this study is to investigate the use of PET-CT scan with 18F-fluorodeoxyglucose (18F-FDG) as a method to predict outcomes in patients with Takayasu arteritis (TAK), as well as to analyze associations between 18F-FDG PET-CT findings with disease relapses, sustained remission, new angiographic lesions, ischemic events, and changes in therapy for TAK. At baseline assessment, 36 TAK patients underwent 18F-FDG PET-CT scan and maximal standardized uptake value (SUVmax) in arteries ≥ 1.3 was predictive for clinical disease activity. Thirty-two TAK patients were then followed-up for a median 83.5 months. Twenty-three (71.9%) patients developed clinical relapses and new arterial lesions were observed in 14 (43.8%) cases. Disease relapses [85.0% vs. 50.0%, p = 0.049; odds ratio (OR): 5.667; 95% confidence interval (95 CI): 1.067–30.085] and the need for changing immunosuppressive therapy (85.0% vs. 41.7%, p = 0.018; OR: 7.933; 95CI: 1.478–42.581) were more frequently found in patients with SUVmax ≥ 1.3 at baseline compared with those presenting SUVmax

BACKGROUND Acute transverse myelitis (ATM) is an infrequent but severe complication of systemic lupus erythematosus (SLE). The purpose of study was to describe clinical features and prognostic factors of patients with SLE-related ATM. METHODS In this medical records review study, data were collected from 60 patients from 16 centers seen between 1996 and 2017 who met diagnostic criteria for SLE and myelitis as defined by the American College of Rheumatology/Systemic International Collaborating Clinics and the Working Group of the Transverse Myelitis Consortium, respectively. Objective neurological impairment was measured with American Spinal Injury Association Impairment Scale (AIS) and European Database for Multiple Sclerosis Grade Scale (EGS). RESULTS Among patients included, 95% (n = 57) were female, and the average age was 31.6 ± 9.6 years. Myelitis developed after diagnosis of SLE in 60% (n = 36). Symmetrical paraparesis with hypoesthesia, flaccidity, sphincter dysfunction, AIS = A/B, and EGS ≥ 8 was the most common presentation. Intravenous methylprednisolone was used in 95% (n = 57), and 78.3% (n = 47) received intravenous cyclophosphamide. Sensory/motor recovery at 6 months was observed in 75% (42 of 56), but only in 16.1% (9 of 56) was complete. Hypoglycorrhachia and EGS ≥ 7 in the nadir were associated with an unfavorable neurological outcome at 6 months (p < 0.05). A relapse rate during follow-up was observed in 30.4% (17 of 56). Hypoglycorrhachia and hypocomplementemia seem to be protective factors for relapse. Intravenous cyclophosphamide was associated with time delay to relapse. CONCLUSIONS Systemic lupus erythematosus-related ATM may occur at any time of SLE course, leading to significant disability despite treatment. Relapses are infrequent and intravenous cyclophosphamide seems to delay it. Hypoglycorrhachia, hypocomplementemia, and EGS at nadir are the most important prognostic factors.

Background There is a lack of information on the role of chronic use of hydroxychloroquine during the SARS-CoV-2 outbreak. Our aim was to compare the occurrence of COVID-19 between rheumatic disease patients on hydroxychloroquine with individuals from the same household not taking the drug during the first 8 weeks of community viral transmission in Brazil. Methods This baseline cross-sectional analysis is part of a 24-week observational multi-center study involving 22 Brazilian academic outpatient centers. All information regarding COVID-19 symptoms, epidemiological, clinical, and demographic data were recorded on a specific web-based platform using telephone calls from physicians and medical students. COVID-19 was defined according to the Brazilian Ministry of Health (BMH) criteria. Mann–Whitney, Chi-square and Exact Fisher tests were used for statistical analysis and two binary Final Logistic Regression Model by Wald test were developed using a backward-stepwise method for the presence of COVID-19. Results From March 29th to May 17st, 2020, a total of 10,443 participants were enrolled, including 5166 (53.9%) rheumatic disease patients, of whom 82.5% had systemic erythematosus lupus, 7.8% rheumatoid arthritis, 3.7% Sjögren’s syndrome and 0.8% systemic sclerosis. In total, 1822 (19.1%) participants reported flu symptoms within the 30 days prior to enrollment, of which 3.1% fulfilled the BMH criteria, but with no significant difference between rheumatic disease patients (4.03%) and controls (3.25%). After adjustments for multiple confounders, the main risk factor significantly associated with a COVID-19 diagnosis was lung disease (OR 1.63; 95% CI 1.03–2.58); and for rheumatic disease patients were diagnosis of systemic sclerosis (OR 2.8; 95% CI 1.19–6.63) and glucocorticoids above 10 mg/ day (OR 2.05; 95% CI 1.31–3.19). In addition, a recent influenza vaccination had a protective effect (OR 0.674; 95% CI 0.46–0.98). Conclusion Patients with rheumatic disease on hydroxychloroquine presented a similar occurrence of COVID-19 to household cohabitants, suggesting a lack of any protective role against SARS-CoV-2 infection.

Aims To determine the factors predictive of disease activity early in the course of SLE (baseline visit). Methods Patients from GLADEL, a multi-national, multi-ethnic, Latin-American lupus cohort were included. Disease activity was evaluated at baseline with the SLEDAI score. Demographic characteristics (age at diagnosis, gender, ethnicity, marital status, educational level, medical coverage and socioeconomic status) were assessed. Disease duration was defined as the time between the fourth ACR criterion and baseline. Time to criteria accrual was defined as the interval between the first and fourth ACR criterion. Use of glucocorticoids was recorded as the highest dose received before the baseline visit. Antimalarials and immunosuppressive drugs were recorded as use or not use. Univariable and multivariable analysis were performed. Model selection was based on backward elimination. Results One thousand two hundred sixty-eight patients were included; 1136 (89.6%) of them were female. Mean age at diagnosis was 29.2 (SD: 12.3) years. Five hundred sixty-five (44.6%) were Mestizo, 539 (42.5%) were Caucasians and 164 (12.9%) were African-Latin-Americans. The mean SLEDAI at baseline was 10.9 (SD: 8.4). Longer time between first and fourth ACR criterion, medical coverage, a dose of prednisone between 15 and 60 mg/d, and the use of antimalarials were factors protective of disease activity, while Mestizo and African-Latin-American ethnicities were predictive factors. Conclusions Mestizo and African-Latin-American ethnicities were predictive whereas antimalarial use, medical coverage, and longer time to criteria accrual were protective of higher disease activity early in the disease course.

Hydroxychloroquine and chloroquine, also known as antimalarial drugs, are widely used in the treatment of rheumatic diseases and have recently become the focus of attention because of the ongoing COVID-19 pandemic. Rheumatologists have been using antimalarials to manage patients with chronic immune-mediated inflammatory rheumatic diseases for decades. It is an appropriate time to review their immunomodulatory and anti-inflammatory mechanisms impact on disease activity and survival of systemic lupus erythematosus patient, including antiplatelet effect, metabolic and lipid benefits. We also discuss possible adverse effects, adding a practical and comprehensive approach to monitoring rheumatic patients during treatment with these drugs.

Objectives This study aimed to compare the clinical features, damage accrual, and survival of patients with familial and sporadic systemic lupus erythematosus (SLE). Methods A multi-ethnic, multinational Latin American SLE cohort was studied. Familial lupus was defined as patients with a first-degree SLE relative; these relatives were interviewed in person or by telephone. Clinical variables, disease activity, damage, and mortality were compared. Odds ratios (OR) and 95% confidence intervals (CI) were estimated. Hazard ratios (HR) were calculated using Cox proportional hazard adjusted for potential confounders for time to damage and mortality. Results A total of 66 (5.6%) patients had familial lupus, and 1110 (94.4%) had sporadic lupus. Both groups were predominantly female, of comparable age, and of similar ethnic distribution. Discoid lupus (OR = 1.97; 95% CI 1.08–3.60) and neurologic disorder (OR = 1.65; 95% CI 1.00–2.73) were significantly associated with familial SLE; pericarditis was negatively associated (OR = 0.35; 95% CI 0.14–0.87). The SLE Disease Activity Index and Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI) were similar in both groups, although the neuropsychiatric (45.4% vs. 33.5%; p = 0.04) and musculoskeletal (6.1% vs. 1.9%; p = 0.02) domains of the SDI were more frequent in familial lupus. They were not retained in the Cox models (by domains). Familial lupus was not significantly associated with damage accrual (HR = 0.69; 95% CI 0.30–1.55) or mortality (HR = 1.23; 95% CI 0.26–4.81). Conclusion Familial SLE is not characterized by a more severe form of disease than sporadic lupus. We also observed that familial SLE has a higher frequency of discoid lupus and neurologic manifestations and a lower frequency of pericarditis.

ObjectiveTo compare the clinical, laboratory and outcome features of SLE patients with and without Jaccoud’s arthropathy (JA) from the Grupo Latino Americano De Estudio del Lupus (GLADEL) cohort.Methods1480 patients with SLE [(34 centres, 9 Latin American countries with a recent diagnosis (≤2 years)] constitute the GLADEL cohort. JA was defined as reducible deformity of the metacarpophalangeal axis, without radiographic erosions at any time. Within this cohort, a nested case–control study was carried out. Control was matched for age, gender and centre in a 1:3 proportion. The variables included were: sociodemographic, clinical and immunological features, disease activity, damage and mortality. Comparisons were performed with Wilcoxon and χ2 tests for continuous and categorical variables, respectively. ORs and 95% CIs and Kaplan-Meier survival curve were estimated.ResultsOf 1480 patients, 17 (1.1%) JA patients were identified; 16 (94.1%) of them were women, mean age: 31.0 years (SD 12.0). Five (29.4%) patients presented JA at SLE diagnosis and 12 (70.6%) after. The median follow-up time and all disease features were comparable in both groups except for a higher frequency of pneumonitis in the patients with JA [4 (23.5) vs 1 (2.0); p=0.012; (OR: 15.4; 95% CI 1.6 to 149.6)]. The SLE disease activity index, Systemic Lupus International Collaborating Clinics/American College of Rheumatology damage Index and the Kaplan-Meier survival curve were similar in both groups.ConclusionJA may tend to appear early in the course of SLE; it seems not to have an impact on disease activity, damage accrual or in survival.

AimA decrease in proteinuria has been considered protective from renal damage in lupus nephritis (LN), but a cut-off point has yet to be established. The aim of this study was to identify the predictors of renal damage in patients with LN and to determine the best cut-off point for a decrease in proteinuria.MethodsWe included patients with LN defined clinically or histologically. Possible predictors of renal damage at the time of LN diagnosis were examined: proteinuria, low complement, anti-double-stranded DNA antibodies, red cell casts, creatinine level, hypertension, renal activity (assessed by the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI)), prednisone dose, immunosuppressive drugs and antimalarial use. Sociodemographic variables were included at baseline. Proteinuria was assessed at baseline and at 12 months, to determine if early response (proteinuria ResultsFive hundred and two patients with systemic lupus erythematosus patients were included; 120 patients (23.9%) accrued renal damage during their follow-up. Early response to treatment (HR=0.58), antimalarial use (HR=0.54) and a high SES (HR=0.25) were protective of renal damage occurrence, whereas male gender (HR=1.83), hypertension (HR=1.86) and the renal component of the SLEDAI (HR=2.02) were risk factors for its occurrence.ConclusionsEarly response, antimalarial use and high SES were protective of renal damage, while male gender, hypertension and higher renal activity were risk factors for its occurrence in patients with LN.

OBJECTIVES To evaluate the impact and risk factors associated with an abnormal exercise test (ET) in systemic inflammatory rheumatic disease (SIRD) patients before commencing supervised physical exercise. METHODS A total of 235 SIRD patients were enrolled in three controlled clinical trials, including 103 RA, 42 SLE and 57 AS patients. The control group consisted of 231 healthy, sedentary subjects matched for age, gender and BMI. All performed an ET, according to Bruce's or Ellestad's protocol. Cardiovascular disease risk factors, medications, comorbidities and details of each SIRD were assessed. RESULTS SIRD patients had a higher percentage of abnormal ETs compared with the control group, especially exercise hypertensive behaviour, higher oxygen consumption, higher resting heart rate and heart rate at the first minute of recovery, and chronotropic incompetence (C-Inc) (P

Background Systemic Lupus Erythematosus (SLE) is an autoimmune disease which impairs the quality of life. The objective of study was to evaluate the effectiveness of Brief Group Psychoanalytic Psychotherapy to improve quality of life, depression, anxiety and coping strategies in SLE patients. Methods In a randomized clinical trial, 80 female SLE patients were allocated into two groups: therapy group (n = 37) and control group (n = 43). Therapy group (TG) attended weekly psychotherapy sessions for 20 weeks; control group (CG) remained on a waiting list. Both groups received standard medical care. Questionnaires and scales were applied by blinded evaluators at baseline (T1) and after 20 weeks (T2): Socioeconomic Status, SLE International Collaborating Clinic/American College of Rheumatology-Damage Index, SLE International Disease Activity, SLE Specific Symptom Checklist, SLE Quality of life, Hospital Anxiety Depression Scale, Coping Strategies Inventory. Intent to treat intra- and inter-group analysis was performed for all variables in T1 and T2 using Qui-square, t-Student, Mann-Whitney and Wilcoxon tests. Analysis of Variance was used to compare categorical variables over time. P < 0.05 was considered significant. Results The mean age of patients was 42 years; 54% were white, with mean disease duration of years 12. At baseline, both groups were homogeneous in all variables, including medications. After 20 weeks of psychotherapy TG was significantly different from CG, with lower frequency of symptoms (p = 0.001), lower level of anxiety (p = 0.019) and depression (p = 0.022), better index in five of six domains of quality of life scale (p ≤ 0.005), including total SLEQOL (p < 0.001) and with higher positive planful problem solving strategy (p = 0.017). No change in disease activity score was observed in both groups. Conclusions Psychoanalytic psychotherapy was effective to improve many domains of quality of life and one positive coping skill and to reduce SLE symptoms, anxiety and depression levels. Brief group psychotherapy can be a useful tool to complement medical care in SLE patients. Trial registration Number NCT01840709.

Background Endothelial progenitor cells (EPCs) are responsible for endothelial damage repair. Takayasu’s arteritis (TA) is a chronic inflammatory disease that affects large vessels. The aim of the study was to evaluate the number of EPCs and the levels of vascular endothelial growth factor (VEGF) and the relationship of these variables in patients with TA. Methods Thirty women with TA and 30 healthy controls were included. EPCs were assessed by flow cytometry and cell culture and VEGF quantification was performed by commercial ELISA kits. Results Ages of patients and controls were similar. The number of EPCs in patients and controls (median (interquartile range) were 0.0073% (0.0081%) vs. 0.0062% (0.0089%), p = 0.779 by flow cytometry and 27.0 (42.3) colony forming units (CFUs) vs. 27.0 (20.5) CFUs, p = 0.473 by cells culture, respectively. VEGF levels in patients and controls was 274.5 (395.5) pg/ml vs. 243.5 (255.3) pg/ml, p = 0.460. There was no difference in the number of EPCs and VEGF level between patients with active and inactive disease. There was a tendency of the number of angioblast-like EPCs in patients taking anti-TNFs to be higher; and in patients using methotrexate to be lower. Conclusion No significant difference was found in the quantification of EPCs and VEGF levels in TA patients compared to controls, and no difference was observed between patients with active and inactive disease.

Systemic lupus erythematosus (SLE), a complex and heterogeneous autoimmune disease, represents a significant challenge for both diagnosis and treatment. Patients with SLE in Latin America face special problems that should be considered when therapeutic guidelines are developed. The objective of the study is to develop clinical practice guidelines for Latin American patients with lupus. Two independent teams (rheumatologists with experience in lupus management and methodologists) had an initial meeting in Panama City, Panama, in April 2016. They selected a list of questions for the clinical problems most commonly seen in Latin American patients with SLE. These were addressed with the best available evidence and summarised in a standardised format following the Grading of Recommendations Assessment, Development and Evaluation approach. All preliminary findings were discussed in a second face-to-face meeting in Washington, DC, in November 2016. As a result, nine organ/system sections are presented with the main findings; an 'overarching' treatment approach was added. Special emphasis was made on regional implementation issues. Best pharmacologic options were examined for musculoskeletal, mucocutaneous, kidney, cardiac, pulmonary, neuropsychiatric, haematological manifestations and the antiphospholipid syndrome. The roles of main therapeutic options (ie, glucocorticoids, antimalarials, immunosuppressant agents, therapeutic plasma exchange, belimumab, rituximab, abatacept, low-dose aspirin and anticoagulants) were summarised in each section. In all cases, benefits and harms, certainty of the evidence, values and preferences, feasibility, acceptability and equity issues were considered to produce a recommendation with special focus on ethnic and socioeconomic aspects. Guidelines for Latin American patients with lupus have been developed and could be used in similar settings. Fil: Pons Estel, Bernardo A..

Modern medicine is in a continuous state of flux given the relentless development of new evidence; thus, it is quite difficult for clinicians to remain abreast of all advances as they happen. Trustworthy clinical practica guidelines (CPGs) rigorously developed following a transparent methodology (http://www.gradeworkinggroup.org/) and including the best available evidence represent one of the best solutions to overcome these problems...

OBJECTIVE The aim of this study was to evaluate the association of socioeconomic status and American College of Rheumatology/Systemic Lupus International Collaborating Clinics Damage Index (SDI) score in Brazilian patients with systemic lupus erythematosus (SLE). METHODS Five hundred twenty-three patients (SLE ACR criteria) 18 years or older who were at 12 months or greater since diagnosis were included. Socioeconomic status was assessed by per-capita income and years of education. Race was categorized as white and nonwhite. The SDI and Mexican SLE Disease Activity Index were used. STATISTICAL ANALYSIS Mean ± SD and median were used for descriptive analysis. Student t test, Mann-Whitney U test, χ test, and Spearman rank correlation coefficient and univariate and multivariate regression analyses were performed. The level of significance was set at 5% for all statistical tests. RESULTS Ninety-six percent were female, 51.2% were nonwhite, and the mean age was 37.8 ± 1.4 years. Disease duration was 8.2 ± 10.3 years and formal education was 10.2 ± 3.5 years. Unemployment among patients was 63.7%, with median monthly per-capita income of US $276. Mean SDI score was 1.4 ± 1.52, and 65.6% had some type of damage (SDI ≥1). Patients with SDI of 1 or greater had lower income (P = 0.039). Nonwhite patients had higher SDI than did white patients (P = 0.005). The SDI presented a positive correlation with disease duration (P < 0.001) and age (P < 0.001) and a negative correlation with years of education (P = 0.001). Working patients had lower SDI than did inactive ones (P ≤ 0.001). In a multivariate analysis, older age, higher disease duration, nonwhite race, low income, and out-of-work profile were associated with damage. CONCLUSIONS Besides nonmodifiable characteristics such as longer disease duration and older age, low income was also associated with damage. Therefore, interventions to give adequate socioeconomic support are necessary to improve outcome, mainly in poorer and nonwhite SLE patients.

ObjectiveTo evaluate disease activity statuses’ (DAS’) impact on systemic lupus erythematosus (SLE) outcomes.Materials and methodsFour DAS were defined: remission off-therapy: SLE Disease Activity Index (SLEDAI)=0, no prednisone or immunosuppressive drugs (IS); remission on-therapy: SLEDAI=0, prednisone ≤5 mg/day and/or IS (maintenance); low (L) DAS: SLEDAI ≤4, prednisone ≤7.5 mg/day and/or IS (maintenance); non-optimally controlled: SLEDAI >4 and/or prednisone >7.5 mg/day and/or IS (induction). Antimalarials were allowed in all. Predefined outcomes were mortality, new damage (increase of at least one Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR) damage index (SDI) point) and severe new damage (increase of at least 3 SDI points). Univariable and multivariable Cox regression models were performed to define the impact of DAS, as time-dependent variable, on these outcomes.Results1350 patients were included, 79 died during follow-up, 606 presented new and 177 severe new damage. In multivariable analyses, remission (on/off-therapy) was associated with a lower risk of new (HR 0.60; 95% CI 0.43 to 0.85), and of severe new damage (HR 0.32; 95% CI 0.15 to 0.68); low disease activity status (LDAS) was associated with a lower risk of new damage (HR 0.66; 95% CI 0.48 to 0.93) compared with non-optimally controlled. No significant effect on mortality was observed.ConclusionsRemission was associated with a lower risk of new and severe new damage; LDAS with a lower risk of new damage after adjusting for other damage confounders.

Objective. The objective of this study was to evaluate the effect of supervised physical exercise on endothelial function, ergospirometric test variables and disease activity in SLE patients. Methods. We conducted a prospective study in which women with SLE who were available to perform physical exercise were allocated to the exercise group (EG) to practise supervised physical exercise for 1 h three times per week for 16 weeks. Those who were not available for this activity were allocated to the control group (CG). Intervention consisted of walking at a heart rate corresponding to the ventilatory 1 threshold obtained from ergospirometry and monitored by a frequency meter. At baseline (T0) and after 16 weeks (T16), patients were assessed for endothelial function by brachial artery (flow-mediated dilation), ergospirometry and disease activity (SLEDAI). Statistical analysis was performed through normality tests, Student’s t-test and non-parametric tests for data with non-normal distribution. P < 0.05 was considered significant. Results. Eighteen patients were allocated in the EG and 20 in the CG. After 16 weeks there was an increase in FMD in the EG [6.3 (6.7)% vs 14.1 (9.1)%, P = 0.006] without a change in the CG [8.4 (8.2)% vs 9.4 (5.7)%, P = 0.598]. Regarding the ergospirometric test, we found improvement in exercise tolerance [12.3 (2.4) vs 13.4 (2.6) min, P = 0.027], maximum speed [7.7 (1.0) vs 8.3 (1.2) km/h, P = 0.027] and threshold speed [5.6 (0.7) vs 6.1 (0.9) km/h, P = 0.005] in the EG without a difference in the CG. There was no difference in the SLEDAI score in both groups. Conclusion. Physical exercise is a useful strategy to improve endothelial function and aerobic capacity without worsening disease activity in SLE patients. Trial registration.

Objective: To evaluate 18F-fluorodeoxyglucose (18F-FDG) uptake on positron emission tomography–computed tomography (PET–CT) and serum levels of different cytokines and matrix metalloproteinases (MMPs) in patients with Takayasu arteritis (TA) and associations with disease activity. Methods: Serum levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-2, IL-6, IL-8, IL-12, IL-18, MMP-3 and MMP-9 were measured in 36 TA patients and 36 controls. Maximum standard uptake value (SUVmax) of 18F-FDG in arterial walls was determined by PET–CT scans. TA patients were classified as active disease, inactive disease and possible active disease. Results: Serum IL-6 and MMP-3 levels were higher in TA patients than in controls (p < 0.001). Serum IL-6 was higher in patients with active disease and in patients with possible active disease than in inactive disease (p < 0.0001). Patients with active disease had higher serum TNFα levels than patients with inactive disease (p = 0.049) while patients with possible active disease presented higher IL-18 levels than patients with inactive disease (p = 0.046). Patients with active disease had higher SUVmax values than those with inactive disease (p = 0.042). By receiver operating characteristic (ROC) curve SUVmax was predictive of active disease in TA and values ≥1.3 were associated with disease activity (p = 0.039). Serum TNF-α levels were higher in patients with SUVmax ≥ 1.3 than
