Risk factors for cardiovascular diseases in patients with systemic lupus erythematosus: an umbrella review.

Cardiovascular disease in patients with systemic lupus erythematosus (SLE) remains one of the most common causes of death and is caused by several factors, including both traditional and disease-specific risk factors. We aimed to systematically appraise the evidence of cardiovascular disease risk factors focusing on the SLE population. The protocol for this umbrella review is registered in PROSPERO (registration no. CRD42020206858). A systematic literature search was conducted in PubMed, Embase, and the Cochrane Library from database inception to June 22, 2022, for systematic reviews and meta-analyzes that examined cardiovascular disease risk factors in patients with SLE. Two reviewers independently extracted data and assessed the quality of the included studies using the "Assessing the Methodological Quality of Systematic Reviews 2 (AMSTER 2)" tool. Of the 102 identified articles, nine systematic reviews were included in this umbrella review. All included systematic reviews were assessed as critically low quality according to the AMSTER 2 tool. The traditional risk factors identified in this study were older age, male sex, hypertension, dyslipidemia, smoking, and a family history of cardiovascular disease. SLE-specific risk factors were long-term disease duration, lupus nephritis, neurological disorders, high disease activity, organ damage, use of glucocorticoids, azathioprine, and antiphospholipid antibodies, including anticardiolipin antibodies and lupus anticoagulant. This umbrella review identified some cardiovascular disease risk factors in patients with SLE; however, the study quality of all included systematic reviews was critically low. Key Points • We examined the evidence of cardiovascular disease risk factors focusing on patients with systemic lupus erythematosus. • We found that long-term disease duration, lupus nephritis, neurological disorders, high disease activity, organ damage, use of glucocorticoids, azathioprine, and antiphospholipid antibodies, including anticardiolipin antibodies and lupus anticoagulant, were cardiovascular disease risk factors among patients with systemic lupus erythematosus. • The review indicates the need for well-validated and high-quality future reviews that assess major adverse cardiovascular events as an outcome in patients with systemic lupus erythematosus.

Perceptions and behaviours related to COVID-19 in patients with rheumatoid arthritis: a cross-sectional study.

OBJECTIVES: To study the perceptions and behavioural changes related to the coronavirus disease 2019 (COVID-19) in patients with rheumatoid arthritis (RA) and determine their associations with patient characteristics, such as health literacy. METHODS: This cross-sectional study was conducted from September to November of 2020 and included 400 outpatients with RA aged 18 and above. We measured self-reported perceptions as outcomes, such as awareness, knowledge and behaviours related to COVID-19. Health literacy and other characteristics as exposures were investigated using self-report questionnaires and electronic health records. To analyse the association between patient factors and the outcomes, multivariable linear and logistic regression models were performed. RESULTS: In total, 365 patients completed the survey. More than half (51%) of patients reported that they were 'very worried' about possible infection with COVID-19, whereas over 80% believed the possibility of getting COVID-19 was low. In the multivariable analyses, patients with low health literacy had limited knowledge about COVID-19 and did not change daily routines and perform preventive measures. CONCLUSIONS: In this pandemic, healthcare providers may need to be aware of more vulnerable individuals and share COVID-19 related information promptly and effectively with their patients. Key Points • This cross-sectional study aimed to investigate the perceptions and behavioural changes related to COVID-19 in patients with RA. • All patients were aware of COVID-19 and most of them worried about getting infected. • Health literacy, age, sex, disease activity and rheumatic drugs were associated with perceptions and behaviours related to COVID-19.
