- Abstract
Objectives: Lipid profiles appear to be altered in SLE patients due to disease activity and inflammation. Cholesterol efflux capacity (CEC) is the ability of high-density lipoprotein cholesterol to accept cholesterol from macrophages. CEC has been linked to cardiovascular events in the general population and is impaired in SLE patients. The aim of this study was to establish whether CEC is related to subclinical carotid atherosclerosis in SLE patients., Methods: The present report is of a cross-sectional study that encompassed 418 individuals: 195 SLE patients and 223 controls. CEC, using an in vitro assay, and lipoprotein serum concentrations were assessed in patients and controls. Carotid intima-media thickness and carotid plaques were evaluated in SLE patients. A multivariable analysis was performed to study the relationship of CEC to SLE-related data, lipid profile and subclinical carotid atherosclerosis., Results: CEC was downregulated in SLE patients [8.1 (4.2) % vs 16.9 (10.4) %, P = 0.004). This occurred independently of traditional cardiovascular risk factors, statin use or other variations in the lipid profile related to the disease. Traditional cardiovascular risk factors, both in patients and controls, and SLE-related data such as activity, severity or damage were not associated with CEC. After multivariable regression analysis including lipid profile-related molecules, CEC was inversely and independently associated with the presence of carotid plaques in SLE patients [odds ratio 0.87 (95% CI: 0.78, 0.97), P = 0.014]., Conclusion: CEC is impaired in SLE patients independently of other inflammation-related lipid profile modifications that occur during the disease. CEC is associated with carotid plaques in SLE patients., (© The Author(s) 2020. Published by Oxford University Press on behalf of the British Society for Rheumatology. All rights reserved.

- Abstract
Objectives: Prevalence of SLE varies among studies, being influenced by study design, geographical area and ethnicity. Data about the prevalence of SLE in Spain are scarce. In the EPISER2016 study, promoted by the Spanish Society of Rheumatology, the prevalence estimate of SLE in the general adult population in Spain has been updated and its association with sociodemographic, anthropometric and lifestyle variables has been explored., Methods: Population-based multicentre cross-sectional study, with multistage stratified and cluster random sampling. Participants were contacted by telephone to carry out a questionnaire for the screening of SLE. Investigating rheumatologists evaluated positive results (review of medical records and/or telephone interview, with medical visit if needed) to confirm the diagnosis. To calculate the prevalence and its 95% CI, the sample design was taken into account and weighing was calculated considering age, sex and geographic origin. Multivariate logistic regression models were defined to analyse which sociodemographic, anthropometric and lifestyle variables included in the telephone questionnaire were associated with the presence of SLE., Results: 4916 subjects aged 20 years or over were included. 16.52% (812/4916) had a positive screening result for SLE. 12 cases of SLE were detected. The estimated prevalence was 0.21% (95% CI: 0.11, 0.40). SLE was more prevalent in the rural municipalities, with an odds ratio (OR) = 4.041 (95% CI: 1.216, 13.424)., Conclusion: The estimated prevalence of SLE in Spain is higher than that described in most international epidemiological studies, but lower than that observed in ethnic minorities in the United States or the United Kingdom., (© The Author(s) 2020.

- Abstract
Objectives: The aims of this study were to study physical activity (PA) in patients with RA by accelerometry and to determine to what degree their mobility is affected by disease activity., Methods: A group of 50 RA patients, without lower limb clinical disease, and 50 age- and sex-matched healthy controls were included in this cross-sectional study. PA was assessed by accelerometry and with the International Physical Activity Questionnaire (IPAQ). We performed multiple regression analysis not only to compare PA between groups, but also to explore the relation between RA features, including disease activity and cardiovascular risk parameters, and PA. In a randomized group of 30 RA patients a test-retest study was carried out in order to determine the correlation between variations in disease activity and PA., Results: The number of minutes of moderate and vigorous activity per day, as evaluated by accelerometry, was significantly lower in RA patients than in healthy controls. In RA patients, accelerometry and IPAQ demonstrated concordance to a moderate degree [quadratic weighed kappa index 0.27 (0.06-0.48), P = 0.02]. HAQ negatively correlated with both IPAQ and accelerometry data. The 28-joint DAS using CRP (DAS28-CRP) was also inversely related with IPAQ. Framingham score and metabolic syndrome were inversely associated with PA in RA patients. Interestingly, variations in PA by accelerometry inversely correlated with changes in RA disease activity (r = -0.42, P = 0.02)., Conclusion: In RA patients, accelerometry is a reliable technique to evaluate PA. This study not only showed that RA patients spend less time doing moderate and vigorous PA than healthy controls, but also PA, as assessed by accelerometry, was sensitive to any changes in disease activity.
