ABSTRACT
Objectives: Patients with systemic lupus erythematosus (SLE) present greater severity of SARS-CoV-2 infection compared to the general population, particularly those with glomerulonephritis and who are treated with glucocorticoids. Likewise, high disease activity and some immunosuppressants have been associated with worse outcomes. The aim of this study was to describe the characteristics of SARS-CoV-2 infection in patients with SLE in Argentina from the SAR-COVID registry and to establish factors associated with a worse outcome. Method(s): Observational study. Patients diagnosed with SLE with confirmed SARS-CoV-2 infection (RT-PCR and/or positive serology) from the SAR-COVID registry were included. Data were collected from August 2020 to March 2022. The outcome of the infection was measured using the World Health Organization-ordinal scale (WHO-OS). Severe COVID-19 was defined as an WHO-OS value >=5. Descriptive analysis, Student's t , Mann Whitney U, ANOVA, Chi2 and Fisher's tests. Multivariable logistic regression. Result(s): A total of 399 patients were included, 93%female, with a mean age of 40.9 years (SD 12.2), 39.6% had at least one comorbidity. At the time of infection, 54.9% were receiving glucocorticoids, 30.8% immunosuppressants, and 3.3% biological agents. SARS-CoV-2 infection was mild in most cases, while 4.6% had a severe course and/or died. The latter had comorbidities, used glucocorticoids, and had antiphospholipid syndrome (APS) more frequently and higher disease activity at the time of infection. In the multivariate analysis, high blood pressure (OR 5.1, 95% CI 1.8-15.0), the diagnosis of APS (4.7, 95% CI 1.2-15.8), and the use of glucocorticoids (10 mg/day or more: OR 5.5, 95% CI 1.6-20.5) were associated with severe hospitalization and/or death from COVID-19 (WHO-EO >= 5). Conclusion(s): In this cohort of SLE patients with confirmed SARS-CoV-2 infection, most had a symptomatic course, 22.1% were hospitalized, and 5% required mechanical ventilation. Mortality was close to 3%. The diagnosis of APS, having high blood pressure, and the use of glucocorticoids were significantly associated with severe COVID-19.
ABSTRACT
Objectives: To compare characteristics of patients with rheumatic disease and COVID-19 in Argentina (SAR-COVID Registry), in contrast to the data reported at the Latin American and global level (Global International Alliance RheumCOVID Registry). Methods: A national, multicenter, longitudinal and observational registry was carried out. Patients older than 18 years, with a diagnosis of rheumatic disease and SARS-CoV-2 infection by PCR or positive serology, were included between August 13, 2020 and April 11, 2021. Demographic data, underlying rheumatic disease, comorbidities, clinical-laboratory characteristics of the SARS-CoV-2 infection, as well as treatments and outcomes. Characteristics of the patients included were compared with the data reported at the Latin American and global level. Descriptive statistics were performed. Comparisons between groups were made using ANOVA, chi2 or Fisher's test. Results: 863 patients from Argentina, 74 patients from Latin America and 583 from the rest of the world were included, mostly women in the three groups (79.4%, 73% and 71% respectively). The most frequent rheumatic diseases in the three groups were rheumatoid arthritis (45.8%, 35%, and 39%, respectively) and systemic lupus erythematosus (18%, 22%, and 14%) (Table 1). In Argentina, fewer patients received specific pharmacological treatment for COVID-19 in relation to the other 2 groups (41.4%, 68% and 43% respectively, p < 0.0001), and there was a lower requirement for non-invasive/invasive mechanical ventilation than in the rest of Latin America and theworld (8.6%vs 31% vs 13%, p < 0.0001). Hospitalization requirement in Argentina was lower than in the rest of Latin America and the rest of theworld (32.8%vs 61% vs 45%, p < 0.0001), as well as mortality (5.8%, 12%and 11%;p 0.0010). 86.9% of patients did not present any complications in Argentina, with a statistically significant difference with the rest of the groups (62% and 77%, with p < 0.0001) (Figure 1). Conclusion: Patients with rheumatic diseases and SARS-CoV-2 infection from Argentina reported in this registry received less specific pharmacological treatment for COVID-19 than those registered in other countries, presented fewer complications and required less ventilatory support. In relation to mortality, although a lower mortality was found in the Argentine registry. The fact that registries have information collected at different periods of the pandemic and different local epidemiological situations, does not allow major conclusions to be drawn.
