ABSTRACT
Importance: Patients with myasthenia gravis (MG) and IST are potentially at increased risk for poor COVID-19 outcome. Objective: To determine whether immunosuppressive therapy (IST) compared to no IST is associated with a higher risk for, first, a symptomatic SARS-CoV-2 infection and, second, a more severe COVID-19 disease course as measured by hospitalization rate and death. Design, setting, and participants: The present study included all available MG patients from the German myasthenia gravis registry, which is a nationwide registry conducted by expert centers since February 2019 (German Clinical Trials Registry DRKS-ID 00024099). Main outcomes and measures: Between May 2020 and June 2021, data were collected on demographics, disease duration, comorbidities, preexistent IST including standard (corticosteroids, azathioprine, mycophenolate mofetil, methotrexate, cyclosporine) and escalation (rituximab, eculizumab) IST, thymectomy, COVID-19 characteristics, and outcomes. COVID-19 was diagnosed with a nasopharyngeal swab by polymerase-chain-reaction. Multiple binary logistic regression models and generalized estimation equation regression models based on matched SARS-CoV-2 infected to non-infected patients were used to estimate the association of IST with SARS-CoV-2 infection. Multiple binary logistic regression models were used to assess the association of IST with outcome of COVID-19 in MG patients. Results: Of 1388 MG patients, 95 (7%) MG patients with a mean age of 58 (SD 18) and median disease duration of 65 months (IQR 27-126) presented with COVID-19. Among them, 39 patients (41%) were male, and 76 (80%) received IST at the time of infection. There were 32 patients (34%) admitted to hospital due to COVID-19, 12 (13%) to the intensive care unit, and a total of 11 patients (12%) died. IST was a risk factor for hospitalization and death in the group of COVID-19 affected MG patients (adjusted odds ratio [OR] 3.04, 95% confi- dence interval [CI] = 1.02-9.06, p=0.046), but not for symptomatic SARS-CoV-2 infection itself in the whole group of MG patients. Conclusions and relevance: In MG patients, preexistent IST was a factor for a severe disease course of COVID-19 but not for the risk for SARS-CoV-2 infection. These data support the consequent implementation of effective strategies to prevent COVID- 19 in this high-risk group.
ABSTRACT
Many religious congregations in the United States have adapted to COVID-19 lockdowns by offering religious services online. This study aims to understand whether congregants from a diverse set of faith traditions expect to attend online or in-person religious services after the pandemic. First, it examines how members of different religious traditions vary in their expectations of future attendance. Second, it explores whether respondents' habituation to online attendance during the pandemic might result in greater preference for future online attendance. This study draws on a non-representative sample of 1609 members of Christian, Jewish, and Hindu communities in four US states surveyed in late 2020 and employs logistic regression models. The findings first suggest a divergence between congregation types that require in-person attendance for certain rituals versus those that do not. Second, habituation of the practice of online attendance may cultivate the desire to sustain this practice into the future. Online religious services have been well received by most congregants, and online services will likely play a useful role across congregation types, albeit at differing levels and with different audiences. Our finding that marginal congregants were more likely to prefer online religious services, while more engaged members preferred in-person attendance, is of relevance to faith leaders.
