    Resumen /Abstract

    Resumen en Español

    Objetivo: La pandemia por coronavirus 2019 (COVID-19), causada por el síndrome respiratorio agudo severo coronavirus 2 (SARS-Cov-2), ha registrado más de 234 millones de casos confirmados y más de 4,7 millones de muertes en todo el mundo hasta el 2 de octubre de 2021. Durante los últimos meses se han publicado un número importante de reportes de COVID-19 en pacientes con enfermedades reumáticas. En este estudio el objetivo es reportar las características clínicas de los pacientes chilenos con enfermedades reumáticas y COVID-19 reportados en la plataforma de registro de médicos “Global Rheumatology Alliance” (GRA).

    Materiales y métodos: Los pacientes chilenos con enfermedades reumáticas y COVID-19 fueron incluidos en el registro informado por médicos COVID-19 GRA.

    Resultados: se incluyeron 54 pacientes. La enfermedad reumática más frecuente fue la artritis reumatoide (AR) con 28 casos (51,9%). 30 pacientes (55,6%) utilizaron corticosteroides, de los cuales 20 (66,7%) utilizaron una dosis de 10 mg o menos. 33 pacientes (61,1%) solo utilizaron FAME convencionales, 4 (7,4%) solo biológicos y 6 (11,1%) la combinación. Un total de 35 pacientes (64,8%) tuvieron que ser hospitalizados. Fallecieron 2 pacientes (3,7%). 26 pacientes de los 35 hospitalizados (74,2%) requirieron algún tipo de soporte ventilatorio, de los cuales 5 (19,2%) precisaron ventilación mecánica no invasiva y 8 (30,8%) invasiva u oxigenación por membrana extracorpórea (ECMO).

    Discusión: La mayoría de los pacientes reumáticos chilenos incluidos fueron hospitalizados, con una baja tasa de mortalidad pero con un alto porcentaje de pacientes que requirieron al menos ventilación mecánica no invasiva.

    Introduction

     

    The coronavirus disease 2019 (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2), has registered more than 234 million confirmed cases and more than 4.7 million deaths throughout the world until October 2, 2021, according to data published by the Johns Hopkins University (1). In Latin America, according to the World Health Organization, by October 2, 2021, almost 47 million cases had been registered, with approximately 1.5 million deaths (2), while Chile reported a total of 1.6 million cases with 37 thousand deaths from COVID-19 (3).

     

    COVID-19 can generate a severe and aggressive illness, requiring hospitalization and ventilatory support, and potentially resulting in death. During the last few months, a significant number of case series and reports of COVID-19 in patients with rheumatic diseases have been published; one of the most important being the registry of the “COVID-19 Global Rheumatology Alliance” (GRA), the response of the rheumatology community to the global pandemic of COVID-19 (4). Since its launch in March 2020, more than 19,000 cases have been reported worldwide through its European and World-wide registries. Most of the GRA reports establish that the risk factors associated with hospitalization in rheumatic patients are the same as those in the general population and there does not seem to be a clear relationship between the activity indices of rheumatic disease and the evolution of COVID-19 or worsening of underlying rheumatic disease secondary to COVID-19. Caution is necessary with some medications such as Rituximab, Sulfasalazine or doses of corticosteroids.

    In this study the objective is to report the clinical characteristics of Chilean patients with rheumatic diseases and COVID-19 reported in the GRA physician registration platform.

     

    Materials and Methods

     

    Chilean patients with rheumatic diseases and COVID-19 were included in the GRA physician registry between April 2020 and August 2021. GRA is the collaborative work of an international group of rheumatologists, researchers and patient partners, surveying people with rheumatic diseases to better understand their experience during the COVID-19 pandemic and explore risk factors for developing COVID-19. 19. All health centers nationwide that wanted to participate in the study could do so, it was voluntary. The study included a single survey asking about medical history and the medications you take to treat your rheumatic disease. The selected patients were adults over 18 years of age with previously diagnosed rheumatic disease and confirmed COVID-19 who attended the emergency services. COVID-19 infection was defined as those individuals who presented suggestive symptoms and/or with compatible polymerase chain reaction (PCR) + or CT Scam compatible. Regarding COVID-19, the duration of symptoms, the status of the infection (resolved or not resolved at the time of the report, or unknown), the use of a specific drug treatment for COVID-19, the need for ventilatory support, infection outcome [death, hospitalization, complications such as acute respiratory distress syndrome (ARDS), sepsis, myocarditis / heart failure, secondary infection, cytokine storm] were also recorded.

    Statistical analysis: The mean and standard deviation (SD) were calculated for the variables with normal distribution, and the median and interquartile range (IQR) were calculated for the variables without normal distribution. All analyzes were performed using the IBM SPSS Statistics version 24 program for Macintosh.

    Ethical Considerations: This study was approved by the Department of Academic Development and Research and the Scientific Ethics Committee of the “Clinica Alemana- Universidad del Desarrollo” Medicine Faculty.

     

    Results

     

    54 patients were included, from April 2020 to August 2021. The mean age of the patients was 53.4 years (SD 14.6), and 36 patients (66.7%) were women. The most common primary rheumatic disease was rheumatoid arthritis (RA) with 28 cases (51.9%), followed by lupus (LES) with 7 cases (13%). At the time of COVID-19 diagnosis, 30 patients (55.6%) were in remission or had minimal or low activity of their underlying rheumatic disease, 8 patients (14.8%) had moderate activity and 8 (14.8%) severe activity, according to the physician appreciation. 30 patients (55.6%) used corticosteroids, of which 20 (66.7%) used a dose of 10 mg or less, and in 18 (60%) the dose was increased after COVID-19 diagnosis. 33 patients (61.1%) used only conventional DMARDs, the most used DMARDs were hydroxychloroquine, 20 patients (37%) and Methotrexate 17 patients (31.5%), 4 patients (7.4%) only biologics, and 6 (11.1%) the combination. No patients were reported using targeted synthetic DMARDs. DMARDs were stopped in 22 patients (51.2%) after COVID-19 diagnosis, methotrexate is the that most frequently stopped with 7 patients (31.8%). Regarding comorbidities, 28 patients (51.9%) were hypertensive, 9 (16.7%) had underlying lung disease, 7 (13%) had diabetes, 1 (1.9%), 13 patients (24.1%) had ever smoked.

    Regarding COVID-19 in 47 (87%) patients the diagnosis was confirmed by polymerase chain reaction (PCR), 4 cases (7.4%) were diagnosed only by symptoms and 3 cases (5.6%) by a compatible CT scan. 52 cases (96.3%) were symptomatic, the main symptoms being fever in 29 patients (53.7%), cough also in 29 (53.7%), and dyspnea in 27 cases (50%) (Table 1).

    Specific drug treatment for COVID-19 was used in 30 patients (55.6%), of these, 16 (29.6%) received corticosteroids, 8 (14.8%) received azithromycin, 6 (11.1%) antimalarials, and 1 (1.9%) received tocilizumab. In 18 of the 30 patients (60%) who used corticosteroids before the diagnosis of COVID-19, the dose was increased after the diagnosis. At the time of registering, 40 patients (76.9%) had resolved symptoms. The duration of symptoms in these patients was a median of 21 days (interquartile range (IQR) 10-31.5). A total of 35 patients (64.8%) had to be hospitalized. 2 patients (3.7%) died. Among the 35 hospitalized patients, 26 (74.2%) required some type of ventilatory support, 13 (24.1%) at least non-invasive mechanical ventilation and of these 8 (14.8%) patients required invasive mechanical ventilation (IMV) or extracorporeal membrane oxygenation (ECMO). None of the registered patients presented a cytokine storm like syndrome.

     

    Discussion and Conclusions 

     

    Since the COVID-19 pandemic began, the question has arisen as to whether patients with pre-existing inflammatory diseases mediated by the immune system, such as rheumatic diseases, are at increased risk of SARS CoV2 infection or severe COVID-19 outcomes. The first GRA report was published in May 2020 (5), where the factors associated with hospitalization were examined in 600 rheumatic patients with COVID-19 from 40 countries, of which 46% (277 patients) required hospitalization. Both, advanced age, and the presence of previous comorbidities were factors associated with hospitalization (as in the general population). The use of high-dose glucocorticoids (≥10 mg per day of prednisone equivalent) was associated with an increased risk of hospitalization. The study also included a preliminary analysis of biological DMARD exposure and found that compared to patients who were not receiving biological DMARDs, they were less like to be hospitalized, regardless of the presence of other risk factors. In the Chilean registry the inclusion of hospitalized patients was favored, and the number of registered cases was low, so performing analysis of associations of risk for hospitalization and worse outcome of infection did not seem appropriate to us. The median of days from onset to resolution of symptoms was 13 days in the global report, while in Chilean patients it was 21 days.

    In September 2020 another GRA (6) study was published comparing the characteristics of 74 patients with rheumatic diseases and COVID-19 reported in Latin America with 583 from the rest of the world. Mortality was similar in both groups (12% in Latin America vs 11% in the rest of the world). However, the Latin American registry included a higher percentage of hospitalized patients (61% in Latin America vs 45% in the rest of the world) and a high percentage needed at least non-invasive ventilation. This was like our Chilean report, but the reported mortality was higher in the Latin American cohort.

    In January 2021, a publication derived from the GRA (7) registry determined the factors associated with death related to COVID-19 in people with rheumatic disease. Of 3729 patients, 1739 (49%) was hospitalized, 187 (6.2%) required invasive ventilation and 390 (10.5%) died. Death was associated with known general factors and disease-specific factors (disease activity and specific medications). The association with moderate/high disease activity highlights. Caution may be required with rituximab, sulfasalazine, glucocorticoid dosages and some immunosuppressants. Mortality was higher, but the percentage of hospitalized patients was lower in this study than that reported in the Chilean registry (10.5% vs 3% deaths, 49% vs 64% hospitalized patients).

    A more recent publication from the GRA (8), with a total of 1,324 patients, concluded that African American, Latinos, and Asian patients were more likely to require hospitalization compared to white patients. Latino patients were also 3 times more likely to require ventilatory support. We think these differences may be due in large part to a bias in the registry, clearly in Chile the registry of hospitalized patients was favored. No differences in mortality were found based on race / ethnicity. The results of this study are like the Chilean data in terms of mortality and the use of at least non-invasive mechanical ventilation reported, even though in Chile the registration of hospitalized patients was favored (64% Chile vs 36% Global).

    This study had some limitations, such as the difficulty in data collection, due to medical exhaustion, the increased care load in the health centers selected to carry out the study, constant changes in the treatment paradigm, therefore, the number of patients included is low compared to those affected by COVID-19 in Chile. Therefore, we did not perform any further association analysis, as it would not reflect the reality of what happened. It is evident that the median number of symptoms is higher than that reported in other studies. This may be because the patients with more days of symptoms were those who attended the health centers and were hospitalized, and these were the patients who were included in the study. the study. It is possible that there is an underreporting of mortality due to patients who did not consult the emergency services, and this would explain the low mortality rate with respect to the global data. In Chilean rheumatic patients, the symptoms of COVID-19 were the classic symptoms described for the disease, a low percentage manifested arthralgia and no activation of the rheumatic disease was reported. There is evidence of less use of corticosteroids and greater use of biological DMARDs in rheumatic patients from the rest of the world compared to Chilean patients, possibly related to accessibility due to economic factors and health policies in each region. Regarding specific treatment for COVID-19, some patients were treated with therapies that were initially believed to work, but later evidence showed that they did not, such as hydroxychloroquine or azithromycin. Only one patient received tocilizumab, probably at the time of registration (early in the pandemic). If we compare the data of patients with rheumatic disease vs the total number of patients with COVID-19 in Chile for the dates of data collection, a higher percentage of hospitalization is evidenced for patients with rheumatic disease 64% vs 9.3%, in relation to mortality are similar 3% vs 2.4%, the reason for the greater number of patients requiring hospitalization may be due to what was previously mentioned and is that only patients who consulted the emergency room were included in the study, and that therefore it is understood they had more severe symptoms of COVID-19. It is not mentioned if the patients were vaccinated because when the data collection began it was not yet available, and Chile started the vaccination process in patients with comorbidities in February 2021, and after that very few patients were registered.

    It is concluded that most of the Chilean rheumatic patients included were hospitalized with a low mortality rate, although with a high percentage of patients who required at least non-invasive mechanical ventilation. No worsening of arthralgias or activation of rheumatic disease was reported at the time of diagnosis of COVID-19
