RESUMEN

BACKGROUND: Systemic lupus erythematosus (SLE) often mimics symptoms of other diseases, and the interval between symptom onset and diagnosis may be long in some of these patients. Aims: To describe the characteristics associated with the time to SLE diagnosis and its impact on damage accrual and mortality in patients with SLE from a Latin American inception cohort. METHODS: Patients were from a multi-ethnic, multi-national Latin-American SLE inception cohort. All participating centers had specialized lupus clinics. Socio-demographic, clinical/laboratory, disease activity, damage, and mortality between those with a longer and a shorter time to diagnosis were compared using descriptive statistical tests. Multivariable Cox regression models with damage accrual and mortality as the end points were performed, adjusting for age at SLE diagnosis, gender, ethnicity, level of education, and highest dose of prednisone for damage accrual, plus highest dose of prednisone, baseline SLEDAI, and baseline SDI for mortality. RESULTS: Of the 1437 included in these analyses, the median time to diagnosis was 6.0 months (Q1-Q3 2.4-16.2); in 721 (50.2%) the time to diagnosis was longer than 6 months. Patients whose diagnosis took longer than 6 months were more frequently female, older at diagnosis, of Mestizo ethnicity, not having medical insurance, and having "non-classic" SLE symptoms. Longer time to diagnosis had no impact on either damage accrual (HR 1.09, 95% CI 0.93-1.28, p = 0.300) or mortality (HR 1.37, 95% CI 0.88-2.12, p = 0.200). CONCLUSIONS: In this inception cohort, a maximum time of 24 months with a median of 6 months to SLE diagnosis had no apparent negative impact on disease outcomes (damage accrual and mortality).

RESUMEN

OBJECTIVES: To compare the correlations of histological class inferences based on clinical manifestations and laboratory tests between rheumatologists and nephrologists, to determine the associations of clinical and laboratory data with histological classes and to develop an instrument that can assist histological class identification in lupus nephritis (LN). METHODS: Retrospective study based on medical records of 80 systemic lupus erythematosus patients (SLICC criteria classification, 2012) who underwent kidney biopsy between 2010 and 2017. Two rheumatologists and two nephrologists received clinical and laboratory data and answered questions regarding which histological class was expected on kidney biopsy. Kappa (K) coefficient was used to assess agreement between evaluators. A decision tree was constructed using the chi-square interaction detector and logistic regression was performed for the development of the proliferative histological class predictor instrument. RESULTS: The mean age and disease duration were 33 ± 10.3 years and 11.5 ± 6.7 years, respectively. The level of agreement between the evaluators and kidney biopsy was poor (global K 0.364 ± 0.029; p < .001). Analyzing clinical and laboratory variables as predictors of proliferative histological class, patients with abnormal urinary sediment and positive anti-dsDNA antibodies presented 13.96 and 4.96 times higher risks of presenting class III or IV, respectively (p < 0.001). Our instrument has a sensitivity of 87.8% and specificity of 80%, using abnormal urinary sediment, anti-dsDNA antibodies, and serum creatinine as variables. CONCLUSIONS: Rheumatologists and nephrologists with experience in treating LN generated evaluations that correlated weakly with kidney biopsy. When kidney biopsy is unavailable or is contraindicated for medical reasons, instruments based on clinical and laboratory predictors may be helpful.

RESUMEN

OBJECTIVES: To evaluate factors associated with COVID-19 severity outcomes in patients with systemic lupus erythematosus (SLE). METHODS: This was a cross-sectional analysis of baseline data of a prospective, multi-stage cohort study-"The ReumaCoV Brazil"-designed to monitor patients with immune-mediated rheumatologic disease (IMRD) during the SARS-CoV-2 pandemic. SLE adult patients with COVID-19 were compared with those without COVID-19. SLE activity was evaluated by the patient global assessment (PGA) and SLE Disease Activity Index 2000 (SLEDAI-2K). RESULTS: 604 SLE patients were included, 317 (52.4%) with COVID-19 and 287 (47.6%) in the control group. SLE COVID-19 patients reported a lower frequency of social isolation and worked more frequently as health professionals. There was no difference in the mean SLEDAI-2K score between groups in the post-COVID-19 period (5.8 [8.6] vs. 4.5 [8.0]; p = 0.190). However, infected patients reported increased SLE activity according to the Patient Global Assessment (PGA) during this period (2.9 [2.9] vs. 2.3 [2.6]; p = 0.031. Arterial hypertension (OR 2.48 [CI 95% 1.04-5.91], p = 0.041), cyclophosphamide (OR 14.32 [CI 95% 2.12-96.77], p = 0.006), dyspnea (OR: 7.10 [CI 95% 3.10-16.23], p < 0.001) and discontinuation of SLE treatment medication during infection (5.38 [CI 95% 1.97-15.48], p = 0.002), were independently associated with a higher chance of hospitalization related to COVID-19. Patients who received telemedicine support presented a 67% lower chance of hospitalization (OR 0.33 [CI 95% 0.12-0.88], p = 0.02). CONCLUSION: Hypertension and cyclophosphamide were associated with a severe outcome, and telemedicine can be a useful tool for SLE patients with COVID-19.

RESUMEN

OBJECTIVE: To develop the first evidence-based Pan American League of Associations for Rheumatology (PANLAR) guidelines for the treatment of Takayasu arteritis (TAK). METHODS: A panel of vasculitis experts developed a series of clinically meaningful questions addressing the treatment of TAK patients in the PICO (population/intervention/comparator/outcome) format. A systematic literature review was performed by a team of methodologists. The evidence quality was assessed according to the GRADE (Grading of Recommendations/Assessment/Development/Evaluation) methodology. The panel of vasculitis experts voted each PICO question and made recommendations, which required ≥70% agreement among the voting members. RESULTS: Eleven recommendations were developed. Oral glucocorticoids are conditionally recommended for newly diagnosed and relapsing TAK patients. The addition of nontargeted synthetic immunosuppressants (e.g., methotrexate, leflunomide, azathioprine, or mycophenolate mofetil) is recommended for patients with newly diagnosed or relapsing disease that is not organ- or life-threatening. For organ- or life-threatening disease, we conditionally recommend tumor necrosis factor inhibitors (e.g., infliximab or adalimumab) or tocilizumab with consideration for short courses of cyclophosphamide as an alternative in case of restricted access to biologics. For patients relapsing despite nontargeted synthetic immunosuppressants, we conditionally recommend to switch from one nontargeted synthetic immunosuppressant to another or to add tumor necrosis factor inhibitors or tocilizumab. We conditionally recommend low-dose aspirin for patients with involvement of cranial or coronary arteries to prevent ischemic complications. We strongly recommend performing surgical vascular interventions during periods of remission whenever possible. CONCLUSION: The first PANLAR treatment guidelines for TAK provide evidence-based guidance for the treatment of TAK patients in Latin American countries.

RESUMEN

OBJECTIVES: To evaluate the incidence of COVID-19 and its main outcomes in rheumatic disease (RD) patients on hydroxychloroquine (HCQ) compared to household cohabitants (HC). METHODS: This is a 24-week nationwide prospective multi-centre cohort with a control group without RD and not using HCQ. All participants were monitored through scheduled phone interviews performed by health professionals. Details regarding COVID-19 symptoms, and epidemiological, clinical, and demographic data were recorded on a specific web-based platform. COVID-19 was defined according to the Brazilian Ministry of Health criteria and classified as mild, moderate or severe. RESULTS: A total of 9,585 participants, 5,164 (53.9%) RD patients on HCQ and 4,421 (46.1%) HC were enrolled from March 29th, 2020 to September 30th, 2020, according to the eligibility criteria. COVID-19 confirmed cases were higher in RD patients than in cohabitants [728 (14.1%) vs. 427 (9.7%), p<0.001] in a 24-week follow-up. However, there was no significant difference regarding outcomes related to moderate/ severe COVID-19 (7.1% and 7.3%, respectively, p=0.896). After multiple adjustments, risk factors associated with hospitalisation were age over 65 (HR=4.5; 95%CI 1.35-15.04, p=0.014) and cardiopathy (HR=2.57; 95%CI 1.12-5.91, p=0.026). The final survival analysis demonstrated the probability of dying in 180 days after a COVID-19 diagnosis was significantly higher in patients over 65 years (HR=20.8; 95%CI 4.5-96.1) and with 2 or more comorbidities (HR=10.8; 95%CI 1.1-107.9 and HR=24.8; 95%CI 2.5-249.3, p=0.006, respectively). CONCLUSIONS: Although RD patients have had a higher COVID-19 incidence than individuals from the same epidemiological background, the COVID-19 severity was related to traditional risk factors, particularly multiple comorbidities and age, and not to underlying RD and HCQ.

RESUMEN

BACKGROUND/OBJECTIVES: 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. METHODS: 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. p < 0.05 was considered significant. RESULTS: After 12 weeks, higher flow-mediated dilation (6.17% vs. 11.14%, p < 0.001) 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, p < 0.001), 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). CONCLUSION: 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.

RESUMEN

BACKGROUND: Myostatin is a protein in the TGF-ß 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.

RESUMEN

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.

RESUMEN

INTRODUCTION: Factors related to presentation of neuropsychiatric (NP) SLE manifestations, early in the course of the disease, and during follow up have not been clearly established. PURPOSE: To identify disease and non-disease related factors associated with NP manifestations in early SLE. METHODS: We included 1193 patients from the GLADEL inception cohort free of NP involvement at cohort entry. We evaluated the association of demographic, clinical and laboratory data with NP involvement during follow-up. STATISTICAL METHODS: Independent factors associated with NP involvement were identified using a multivariable Cox regression model. RESULTS: Factors independently associated with NP manifestations were: mestizo ethnicity (HR 1.701, 95% CI 1.282-2.258, p = 0.0002), myalgias/myositis (HR 1.832, 95% CI 1.335-2.515, p = 0.0002), pneumonitis (HR 2.476, 95% CI 1.085-5.648, p = 0.0312), shrinking lung (HR 2.428, 95% CI 1.074-5.493, p = 0.0331) and hemolytic anemia (HR 1.629, 95% CI 1.130-2.347, p = 0.0089). Longer disease duration at cohort entry (13 to 24 months) was associated with a lower risk of developing NP manifestations (HR 0.642, 95% CI 0.441-0.934, p = 0.0206). CONCLUSIONS: Patients with myalgias/myositis, pneumonitis, shrinking lung and hemolytic anemia are at higher risk of NP involvement, whereas longer disease duration at cohort entry is associated with a lower risk of developing NP involvement.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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 < 1.3. No associations were found between SUVmax ≥ or < 1.3 in large arteries at baseline and the development of ischemic events, sustained remission or new angiographic lesions. In multivariate analysis, associations between baseline SUVmax ≥ 1.3 and disease relapses were not independent (hazard ratio: 1.07; 95 CI 0.39-2.92; p = 0.892). In conclusion, arterial SUVmax is marginally associated with disease relapses and with the need to change therapy in TAK. 18F-FDG uptake in large arteries is not associated with the development of new arterial lesions in TAK.

RESUMEN

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.

RESUMEN

OBJECTIVE: To evaluate disease activity statuses' (DAS') impact on systemic lupus erythematosus (SLE) outcomes. MATERIALS AND METHODS: Four 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. RESULTS: 1350 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. CONCLUSIONS: Remission 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.

RESUMEN

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.

RESUMEN

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 < 0.001). The disease itself was involved with higher likelihood of having an abnormal ET [Odds ratio (OR) = 12.0, 95% CI: 2.5, 56.7; P = 0.002 for SLE; OR = 13.56, 95% CI: 6.16, 29.8; P < 0.001 for RA; and OR = 4.31, 95% CI: 1.17, 15.8; P = 0.028, for AS]. Each 10-year increment of age increased the chance of having an abnormal ET by 13% (P = 0.008) in AS patients, as well as hypertension (OR = 7.14, 95% CI: 1.61, 31.6; P = 0.01). Regarding C-Inc, age played a protective role (OR = 0.88, 95% CI: 0.78, 0.99; P = 0.043) in SLE, and ASDAS-ESR was associated with a higher risk in AS (OR = 2.73, 95% CI: 0.93, 8.0; P = 0.067). CONCLUSION: Our results showed a higher prevalence of abnormal ETs in asymptomatic cardiovascular SIRD patients, and the disease itself was associated with a higher likelihood of having an abnormal test, emphasizing the relevance and need of performing it before starting supervised physical exercise.

RESUMEN

OBJECTIVES: The aim of this study was to evaluate the efficacy of atorvastatin to reduce the plasma levels of TNF system molecules (TNF-α, sTNFR1 and sTNFR2) and to assess their association with risk factors for accelerate atherosclerosis and clinical disease activity scores in SLE patients. METHODS: In a previous study, 64 female SLE patients received 20 mg/day of atorvastatin and 24 SLE patients (non-treated group) were followed for 8 weeks. Plasma levels of TNF-α, sTNFR 1 and sTNFR 2 were measured by ELISA, at baseline and at the end of the study. RESULTS: The plasma levels of sTNFR1 and sTNFR 2 showed a positive correlation with SLEDAI score. We also found a positive correlation between TNF-α and sTNFR 1 levels and SLICC score. Patients with current nephritis and patients with anti-ds-DNA antibodies presented higher sTNFR1 and sTNFR2 levels. Patients with abdominal obesity and arterial hypertension also had higher plasma levels of soluble receptors. At the end of 8 weeks, we observed a significant decrease in sTNFR1 plasma levels in patients receiving atorvastatin [median (percentile), 876.5 (717-1284 pg/ml) vs. 748 (629.6-917.3 pg/ml), p=0.03], without difference regarding TNF-α and sTNFR2 plasma levels. The SLEDAI and SLICC scores were independent determinants of the plasma levels of sRTNF1. CONCLUSIONS: Atorvastatin reduced soluble receptors of TNF-α. The plasma levels of TNF-α, sTNFR1 and sTNFR2 may play a role in SLE activity and atherosclerosis, and might be evaluated as targets for new therapies.

RESUMEN

OBJECTIVE: This study describes the utility scores of the SF-6D, standardized for the Brazilian urban population. METHODS: Five thousand individuals, over the age of 15, were assessed in the five regions of the country, in 16 capitals. The sample consisted of representative quotas of the Brazilian population. The selection of households was random. Face-to-face approach was applied in the household interviews. The SF-6D questionnaire was used to assess the measure of utility. Sociodemographics, household income and work status were also evaluated. RESULTS: The mean score of utility assessed by the SF-6D for the study population was 0.82 (015). The scores were lower for females (0.79), and as age increases, the utility scores progressively decrease. Individuals who reported health problems affecting their work activities presented the lowest scores (0.64). CONCLUSIONS: This study describes the utility scores using the SF-6D, standardized for the Brazilian urban population. These values will be useful for understanding the impact of interventions on health and quality of life in the population, assisting decision-making in the health sector.

RESUMEN

The disability caused by the musculoskeletal signs and symptoms affects the quality of life of a population, especially that related to health. The objective of this study is to evaluate the functional capacity of individuals of the Brazilian population who presented musculoskeletal signs and symptoms (MSK-S). The prevalence of MSK-S was evaluated in 5000 individuals (>15 years) in 16 capitals from the five regions of Brazil using the COPCORD Core Questionnaire. Those individuals (n = 2494) that experienced MSK-S and referred some level of disability at the time of the interview were invited to complete the Health Assessment Questionnaire-Disability Index (HAQ-DI). The HAQ-DI scores were compared among regions, and subgroups according to gender, age and type of activity. Three hundred ninety-four (7.9 %) participants reported disability at the time of the interview. The average score of HAQ-DI was 1.09 (SD = 0.71), and the Brazilian region with the highest level of disability was the North region. Among individuals without history of trauma, the disability was higher when the duration of MSK-S was longer. Disability was shown to worsen with increasing age, and the group with 25-34 years showed the lowest scores. Females showed worse functional capacity scores compared to males (p = 0.002). Individuals showed higher degrees of difficulty or were incapable of performing the activities walking, reaching, usual activities and dressing. MSK-S reduce the functional capacity of individuals of the Brazilian general population. The reduction in functional capacity was mainly observed in individuals with chronic musculoskeletal complaints not due to trauma, as well as in female gender and in advancing age.

RESUMEN

BACKGROUND: Generic drugs (GDs) offer a way to reduce health spending without sacrificing quality. Despite this, there are doubts as to their acceptance by the population. This work aims to assess perceptions of GDs among the Brazilian population. METHODS: We conducted a national household survey face-to-face between April and May 2013, with 5000 individuals aged over 15 years. The questions explored socioeconomic and demographic characteristics, the use of GDs, and perceptions about GDs as compared to brand drugs (BDs). The chi-square test was used to examine the associations between the perceptions and the characteristics of the population. RESULTS: Of the 5000 participants, 51.3% were women, 40.2% were white, 48.6% were between 15 and 34 years of age, and 52.3% had income of less than two minimum wages (US$627.78). In terms of the use of GDs, 44.6% of the participants were taking or had taken GDs in the past three months, with the highest figures among the elderly (61.1%) and female (49.2%) populations. Regarding perceptions, 30.4% of the respondents considered GDs less effective than BDs; provided the same price, 59% would prefer BD, and 45.8% agreed that physicians prefer to prescribe GDs. The most negative perceptions about GDs were observed among lower income, elderly and nonwhite populations. CONCLUSION: The findings provide a better understanding of Brazilians' perceptions regarding GDs. This should be considered when formulating healthcare policies aiming at improving access to effective and quality drugs, and reduction of health costs.
