Factors Associated With Mortality in Patients With Immune-Mediated Rheumatic Diseases and COVID-19 From Latin America: Data From Argentina, Mexico, and Brazil.

OBJECTIVE: To describe characteristics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in patients with rheumatic immune-mediated inflammatory diseases (IMIDs) from Argentina, Mexico and Brazil, and to assess factors associated with mortality in this population. METHODS: Data from 3 national registries, SAR-COVID (Argentina), CMR-COVID (Mexico), and ReumaCoV-Brasil (Brazil), were combined. Adult patients with IMIDs and SARS-CoV-2 infection were recruited. Sociodemographic data, comorbidities, IMID clinical characteristics and treatment, and SARS-CoV-2 infection presentation and outcomes were recorded. RESULTS: A total of 4827 individuals were included: 2542 (52.7%) from SAR-COVID, 1167 (24.2%) from CMR-COVID, and 1118 (23.1%) from ReumaCoV-Brasil. Overall, 82.1% were female with a mean age of 49.7 (SD, 14.3) years; 22.7% of the patients were hospitalized, and 5.3% died because of COVID-19 (coronavirus disease 2019). Argentina and Brazil had both 4% of mortality and Mexico 9.4%. In the multivariable analysis, older age (≥60 years; odds ratio [OR], 7.4; 95% confidence interval [CI], 4.6-12.4), male sex (OR, 1.5; 95% CI, 1.1-2.1), living in Mexico (OR, 3.0; 95% CI, 2.0-4.4), comorbidity count (1 comorbidity: OR, 1.5; 95% CI, 1.0-2.1), diagnosis of connective tissue disease or vasculitis (OR, 1.8; 95% CI, 1.3-2.4), and other diseases (OR, 2.6; 95% CI, 1.6-4.1) compared with inflammatory joint disease, high disease activity (OR, 4.2; 95% CI, 2.5-7.0), and treatment with glucocorticoids (OR, 1.9; 95% CI, 1.4-2.5) or rituximab (OR, 4.2; 95% CI, 2.7-6.6) were associated with mortality. CONCLUSIONS: Mortality in patients with IMIDs was particularly high in Mexicans. Ethnic, environmental, societal factors, and different COVID-19 mitigation measures adopted have probably influenced these results.

Does the Use of Immunosuppressive Drugs Impact on SARS-CoV-2 Infection Outcome? Data From A National Cohort of Patients With Immune-Mediated Inflammatory Diseases (SAR-COVID Registry).

BACKGROUND/OBJECTIVE: This study describes the impact of immunomodulatory and/or immunosuppressive (IM/IS) drugs in the outcomes of COVID-19 infection in a cohort of patients with immune-mediated inflammatory diseases (IMIDs). METHODS: Adult patients with IMIDs with a confirmed SARS-CoV-2 infection were included. Data were reported by the treating physician between August 13, 2020 and July 31, 2021. Sociodemographic data, comorbidities, and DMARDs, as well as clinical characteristics, complications, and treatment of the SARS-CoV-2 infection, were recorded. Descriptive analysis and multivariable logistic regression models were carried out. RESULTS: A total of 1672 patients with IMIDs were included, of whom 1402 were treated with IM/IS drugs. The most frequent diseases were rheumatoid arthritis (47.7%) and systemic lupus erythematosus (18.4%). COVID-19 symptoms were present in 95.2% of the patients. A total of 461 (27.6%) patients were hospitalized, 8.2% were admitted to the intensive care unit, and 4.4% died due to COVID-19.Patients without IM/IS treatment used glucocorticoids less frequently but at higher doses, had higher levels of disease activity, were significantly older, were more frequently hospitalized, admitted to the intensive care unit, and died due to COVID-19. After adjusting for these factors, treatment with IM/IS drugs was not associated with a worse COVID-19 outcome (World Health Organization-Ordinal Scale ≥5) (odds ratio, 1.24; 95% confidence interval, 0.73-2.06). CONCLUSIONS: SAR-COVID is the first multicenter Argentine registry collecting data from patients with rheumatic diseases and SARS-CoV-2 infection. After adjusting for relevant covariates, treatment with IM/IS drugs was not associated with severe COVID-19 in patients with IMIDs. STUDY REGISTRATION: This study has been registered in ClinicalTrials.gov under the number NCT04568421.

Sociodemographic and clinical factors associated with poor COVID-19 outcomes in patients with rheumatic diseases: data from the SAR-COVID Registry.

BACKGROUND/OBJECTIVE: This study aims to describe the course and to identify poor prognostic factors of SARS-CoV-2 infection in patients with rheumatic diseases. METHODS: Patients ≥ 18 years of age, with a rheumatic disease, who had confirmed SARS-CoV-2 infection were consecutively included by major rheumatology centers from Argentina, in the national, observational SAR-COVID registry between August 13, 2020 and July 31, 2021. Hospitalization, oxygen requirement, and death were considered poor COVID-19 outcomes. RESULTS: A total of 1915 patients were included. The most frequent rheumatic diseases were rheumatoid arthritis (42%) and systemic lupus erythematosus (16%). Comorbidities were reported in half of them (48%). Symptoms were reported by 95% of the patients, 28% were hospitalized, 8% were admitted to the intensive care unit (ICU), and 4% died due to COVID-19. During hospitalization, 9% required non-invasive mechanical ventilation (NIMV) or high flow oxygen devices and 17% invasive mechanical ventilation (IMV). In multivariate analysis models, using poor COVID-19 outcomes as dependent variables, older age, male gender, higher disease activity, treatment with glucocorticoids or rituximab, and the presence of at least one comorbidity and a greater number of them were associated with worse prognosis. In addition, patients with public health insurance and Mestizos were more likely to require hospitalization. CONCLUSIONS: In addition to the known poor prognostic factors, in this cohort of patients with rheumatic diseases, high disease activity, and treatment with glucocorticoids and rituximab were associated with worse COVID-19 outcomes. Furthermore, patients with public health insurance and Mestizos were 44% and 39% more likely to be hospitalized, respectively. STUDY REGISTRATION: This study has been registered in ClinicalTrials.gov under the number NCT04568421. Key Points • High disease activity, and treatment with glucocorticoids and rituximab were associated with poor COVID-19 outcome in patients with rheumatic diseases. • Some socioeconomic factors related to social inequality, including non-Caucasian ethnicity and public health insurance, were associated with hospitalization due to COVID-19.

Disease activity at conception predicts lupus flare up to two years after birth: A multicentre long term follow-up study.

OBJECTIVE: To assess predicting factors that might influence systemic lupus erythematosus (SLE) disease activity in women in an extended follow-up period of two years after giving birth with clinical assessments every three months. METHODS: The study was design as an international retrospective study, enrolling 119 women with a first birth and with a two years follow-up. RESULTS: Joint involvement was present in 80% of patients, acute cutaneous in 64%, haematological in 54%, renal in 41% and 75% of patients were positive for anti-dsDNA. The mean SLE disease activity index 2000 (SLEDAI-2K) at diagnosis was 13.5±6.8 and at first birth was 2.8±4.4. At follow-up, 51.3% of patients had at least one flare after a mean time after birth of 9±6.3 months (mean flare per patient 0.94±1.1). The most frequent flare manifestations were joint involvement (48%), renal (33%), cutaneous (28%) and haematologic (20%). Patients with remission of disease (SLEDAI-2K=0; no clinical or laboratory manifestations of SLE) at conception had significantly lower rates of flares (18/49-37% vs. 43/70-61%; p=0.008). Patients who experienced a flare during pregnancy (17 patients) had higher rates of flares during follow-up (76% vs. 47%; p=0.019), lower time for first flare (4.4±2.3 months vs. 10.3±6.5; p<0.001), lower rate of remission of disease at conception (12% vs. 46%; p<0.001), lower rates of SLEDAI-2K at conception (5.9±5.6 vs. 2.3±4; p<0.001) and lower rates of exclusive breastfeeding (24% vs. 57%: p=0.009). Results were confirmed after performing multivariate analysis. CONCLUSION: Remission at conception can influence SLE disease positively, even at long-term. Planned pregnancy counseling is fundamental when managing SLE patients.

Características clínicas y evolución de la infección por SARS-CoV-2 en pacientes con lupus eritematoso sistémico en Argentina: datos del registro nacional SAR-COVID / Clinical characteristics and course of SARS-CoV-2 infection in patients with systemic lupus erythematosus in Argentina: data from the SAR-COVID national registry

Introducción: el lupus eritematoso sistémico (LES) es una enfermedad sistémica que se ha asociado a mayor severidad con la infección por SARS-CoV-2. Particularmente la alta actividad de la enfermedad y algunos inmunosupresores se han vinculado a peores desenlaces. Objetivos: describir las características por SARS-CoV-2 en pacientes con LES en Argentina del registro SAR-COVID y establecer los factores asociados a peor desenlace de la misma. Materiales y métodos: estudio observacional. Se incluyeron pacientes con diagnóstico de LES con infección confirmada por SARS-CoV-2 (RT-PCR y/o serología positiva) del registro SAR-COVID. Los datos se recolectaron desde agosto de 2020 hasta marzo de 2022. El desenlace de la infección se midió mediante la escala ordinal de la Organización Mundial de la Salud (EO-OMS). Se definió COVID-19 severo con un valor EO-OMS ≥5. Análisis descriptivo, test T de Student, test de Mann Whitney U, ANOVA, chi2 y Fisher. Regresión logística múltiple. Resultados: se incluyeron 399 pacientes, el 93% de sexo femenino, con una edad media de 40,9 años (DE 12,2). El 39,6% tenía al menos una comorbilidad. Al momento de la infección, el 54,9% recibía glucocorticoides, el 30,8% inmunosupresores y el 3,3% agentes biológicos. La infección por SARS-CoV-2 fue leve en la mayoría de los casos, mientras que un 4,6% tuvo curso severo y/o falleció. Estos últimos presentaban comorbilidades, usaban glucocorticoides y tenían síndrome antifosfolipídico (SAF) con mayor frecuencia y mayor actividad de la enfermedad al momento de la infección. En el análisis multivariado, la hipertensión arterial, el diagnóstico de SAF y el uso de glucocorticoides se asociaron a hospitalización severa y/o muerte por COVID-19 (EO-OMS ≥5). Conclusiones: en esta cohorte de pacientes con LES con infección por SARS-CoV-2 confirmada, la mayoría cursó de manera sintomática, un 22,1% fue hospitalizado y un 5% requirió ventilación mecánica. La mortalidad fue cercana al 3%. El diagnóstico de SAF, tener hipertensión arterial y el uso de glucocorticoides se asociaron significativamente con COVID-19 severo.

Introduction: systemic lupus erythematosus (SLE) is a systemic disease that has been associated with greater severity with SARS-CoV-2 infection. Particularly high disease activity and some immunosuppressants have been linked to worse outcomes. Objectives: to describe the characteristics due to SARS-CoV-2 in patients with SLE in Argentina from the SAR-COVID registry and to establish the factors associated with a worse outcome of the same. Materials and methods: 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 was 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 test, Mann Whitney U, ANOVA, chi2 and Fisher. Multiple logistic regression. Results: 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, the diagnosis of APS, and the use of glucocorticoids were associated with severe hospitalization and/or death from COVID-19 (WHO-EO ≥5). Conclusions: 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.

Environmental and societal factors associated with COVID-19-related death in people with rheumatic disease: an observational study.

Background: Differences in the distribution of individual-level clinical risk factors across regions do not fully explain the observed global disparities in COVID-19 outcomes. We aimed to investigate the associations between environmental and societal factors and country-level variations in mortality attributed to COVID-19 among people with rheumatic disease globally. Methods: In this observational study, we derived individual-level data on adults (aged 18-99 years) with rheumatic disease and a confirmed status of their highest COVID-19 severity level from the COVID-19 Global Rheumatology Alliance (GRA) registry, collected between March 12, 2020, and Aug 27, 2021. Environmental and societal factors were obtained from publicly available sources. The primary endpoint was mortality attributed to COVID-19. We used a multivariable logistic regression to evaluate independent associations between environmental and societal factors and death, after controlling for individual-level risk factors. We used a series of nested mixed-effects models to establish whether environmental and societal factors sufficiently explained country-level variations in death. Findings: 14 044 patients from 23 countries were included in the analyses. 10 178 (72·5%) individuals were female and 3866 (27·5%) were male, with a mean age of 54·4 years (SD 15·6). Air pollution (odds ratio 1·10 per 10 µg/m3 [95% CI 1·01-1·17]; p=0·0105), proportion of the population aged 65 years or older (1·19 per 1% increase [1·10-1·30]; p<0·0001), and population mobility (1·03 per 1% increase in number of visits to grocery and pharmacy stores [1·02-1·05]; p<0·0001 and 1·02 per 1% increase in number of visits to workplaces [1·00-1·03]; p=0·032) were independently associated with higher odds of mortality. Number of hospital beds (0·94 per 1-unit increase per 1000 people [0·88-1·00]; p=0·046), human development index (0·65 per 0·1-unit increase [0·44-0·96]; p=0·032), government response stringency (0·83 per 10-unit increase in containment index [0·74-0·93]; p=0·0018), as well as follow-up time (0·78 per month [0·69-0·88]; p<0·0001) were independently associated with lower odds of mortality. These factors sufficiently explained country-level variations in death attributable to COVID-19 (intraclass correlation coefficient 1·2% [0·1-9·5]; p=0·14). Interpretation: Our findings highlight the importance of environmental and societal factors as potential explanations of the observed regional disparities in COVID-19 outcomes among people with rheumatic disease and lay foundation for a new research agenda to address these disparities.

An Argentinean cohort of patients with rheumatic and immune-mediated diseases vaccinated for SARS-CoV-2: the SAR-CoVAC Registry-protocol and preliminary data.

BACKGROUND/OBJECTIVE: To evaluate the efficacy and safety of SARS-CoV-2 vaccine in patients with rheumatic and immune-mediated inflammatory diseases (IMIDs) in Argentina: the SAR-CoVAC registry. METHODS: SAR-CoVAC is a national, multicenter, and observational registry. Adult patients with rheumatic or IMIDs vaccinated for SARS-CoV-2 were consecutively included between June 1 and September 17, 2021. Sociodemographic data, comorbidities, underlying rheumatic or IMIDs, treatments received, their modification prior to vaccination, and history of SARS-CoV-2 infection were recorded. In addition, date and place of vaccination, type of vaccine applied, scheme, adverse events (AE), disease flares, and new immune-mediated manifestations related to the vaccine were analyzed. RESULTS: A total of 1234 patients were included, 79% were female, with a mean age of 57.8 (SD 14.1) years. The most frequent diseases were rheumatoid arthritis (41.2%), osteoarthritis (14.5%), psoriasis (12.7%), and spondyloarthritis (12.3%). Most of them were in remission (28.5%) or low disease activity (41.4%). At the time of vaccination, 21% were receiving glucocorticoid treatment, 35.7% methotrexate, 29.7% biological (b) disease modifying anti-rheumatic drugs (DMARD), and 5.4% JAK inhibitors. In total, 16.9% had SARS-CoV-2 infection before the first vaccine dose. Most patients (51.1%) received Gam-COVID-Vac as the first vaccine dose, followed by ChAdOx1 nCoV-19 (32.8%) and BBIBP-CorV (14.5%). Half of them (48.8%) were fully vaccinated with 2 doses; 12.5% received combined schemes, being the most frequent Gam-COVID-Vac/mRAN-1273. The median time between doses was 51 days (IQR 53). After the first dose, 25.9% of the patients reported at least one AE and 15.9% after the second, being flu-like syndrome and local hypersensitivity the most frequent manifestations. There was one case of anaphylaxis. Regarding efficacy, 63 events of SARS-CoV-2 infection were reported after vaccination, 19% occurred during the first 14 days post-vaccination, 57.1% after the first dose, and 23.8% after the second. Most cases (85.9%) were asymptomatic or mild and 2 died due to COVID-19. CONCLUSIONS: In this national cohort of patients, the most common vaccines used were Gam-COVID-Vac and ChAdOx1 nCoV-19. A quarter of the patients presented an AE and 5.1% presented SARS-CoV-2 infection after vaccination, in most cases mild. STUDY REGISTRATION: This study has been registered in ClinicalTrials.gov under the number: NCT04845997. Key Points • This study shows real-world data about efficacy and safety of SARS-CoV-2 vaccination in patients with rheumatic and immune-mediated inflammatory diseases. Interestingly, different types of vaccines were used including vector-based, mRNA, and inactivated vaccines, and mixed regimens were enabled. • A quarter of the patients presented an adverse event. The incidence of adverse events was significantly higher in those receiving mRAN-1273 and ChAdOx1 nCoV-19. • In this cohort, 5.1% presented SARS-CoV-2 infection after vaccination, in most cases mild.

Miocardiopatía no compactada como causa de Insuficiencia Cardíaca en Lupus Eritematoso Sistémico / Non compacted cardiomyopathy as a cause of Heart Failure in Lupus Erythematosus Systemic

La Miocardiopatía no compactada (MCNC) representa una anomalía de la morfología miocárdica frecuentemente asociada a una etiología genética, sin embargo, hay escasas descripciones de su asociación con enfermedades autoinmunes. Se presenta revisión de la literatura y el caso de una paciente lúpica que ingresa con signos de insuficiencia cardiaca descompensada con confirmación de VINC por ecocardiograma y resonancia magnética nuclear cardiaca (RMN-C).

Non compacted cardiomyopathy (NCNC) frequently represents an abnormality of myocardial morphology associated with a genetic etiology, however, there are few descriptions of its association with autoimmune diseases. We present a review of the literature and the case of a lupus patient who was admitted with signs of decompensated heart failure with confirmation of VINC by echocardiography and cardiac nuclear magnetic resonance (C-MRI).
