RESUMO
Data on COVID-19 re-infections in patients with systemic rheumatic diseases (SRDs) are lacking. We aimed to describe the course and outcomes of COVID-19 re-infections in these patients versus controls. In this single-center retrospective study, we included 167 consecutive SRD patients with at least one COVID-19 re-infection (mean age 47.3 years, females 70.7%). SRD patients were compared in terms of patient-perceived COVID-19 re-infection severity and hospitalizations/deaths with 167 age/sex-matched non-SRD controls. Logistic regression analysis was performed to assess potential milder re-infection versus primary infection severity, adjusting for study group, demographics (age, sex), vaccination status, body mass index, smoking, and comorbidities. 23 and 7 out of 167 re-infected SRD patients experienced two and three re-infections, respectively, which were comparable to the re-infection rates in controls (two: 32; and three: 2) who also had comparable COVID-19 vaccination history (89% and 95% vaccinated, respectively). In the initial infection, patients with SRDs were hospitalized (7.2% versus 1.8%, p = 0.017), and had received antiviral treatment (16.1% versus 4.7%, p < 0.001) more frequently than controls. However, hospitalizations (1.8% vs 0.6%) and antiviral treatment (7.8% vs 3.5%) did not differ (p > 0.05) between patients and controls at the first re-infection, as well as during the second and third re-infection; no deaths were recorded. Perceived severity of re-infections was also comparable between patients and controls (p = 0.847) and among those on biologic DMARDs or not (p = 0.482). In multivariable analysis, neither SRDs presence nor demographics or comorbidities were associated with COVID-19 re-infection severity. COVID-19 re-infection severity (patient-perceived/hospitalizations/deaths) did not differ between SRDs and controls.
RESUMO
OBJECTIVES: The 2022 EULAR recommendations for cardiovascular risk management in patients with rheumatic disorders, including SLE, call for rigorous management of cardiovascular risk factors (CVRF). The impact of CVRF target attainment on atherosclerotic plaque progression hasn't been previously evaluated in prospective ultrasound studies. METHODS: A total of 115 patients with SLE and 1:1 age and sex-matched healthy controls who had a baseline carotid and femoral ultrasound examination in our cardiovascular research unit were invited for a 7-year follow-up assessment of new plaque development. We aimed to compare the incidence of plaque progression between SLE patients and controls and reveal the extent to which it is affected by the attainment of European Society of Cardiology (ESC) targets for modifiable CVRFs (blood pressure, smoking status, body weight, lipids and physical activity), and disease-related features (disease duration, disease activity, autoantibodies, treatments). RESULTS: Eighty-six SLE patients and 42 controls had a 7-year follow-up carotid and femoral plaque examination. New plaque development was observed in 32/86 patients vs 8/42 controls (P = 0.037). Patients with SLE had a 4-fold higher risk for plaque progression than controls (OR: 4.16, CI: 1.22, 14.19, P = 0.023), adjusting for potential confounders. Multivariate regression analyses showed a 50% decrease in plaque progression for every modifiable CVRF fulfilling ESC targets (OR: 0.56, CI: 0.34, 0.93, P = 0.026). CONCLUSION: Patients with SLE develop a rapid progression of atherosclerotic plaques which may be drastically reduced by CVRF target attainment according to ESC guidelines.
