Epidemiology and outcomes of novel coronavirus 2019 in patients with immune-mediated inflammatory diseases

Abstract

Purpose of review 

The novel coronavirus 2019 (COVID-19) pandemic is of special concern for patients with immune-mediated inflammatory disease (IMID) and those who care for them because of the potential for worse outcomes. This article analyzes peer-reviewed research on the epidemiology and outcomes of COVID-19 in those with IMID.

Recent findings 

Published literature on approximately 1400 patients was included from rheumatology, gastroenterology, and dermatology. Data suggest that those who are older and have comorbidities have poorer outcomes. This is consistent with the reports from the general population of patients with COVID-19. Adjusted analyses from the largest published studies demonstrate independent effects of systemic glucocorticoids, as well as age and comorbidities with poorer COVID-19 outcomes (SECURE-IBD registry, n = 525; COVID-19 Global Rheumatology Alliance registry, n = 600); biologic or targeted synthetic disease-modifying antirheumatic drug therapy has not been associated with more severe outcomes. These early results will require validation in population-based studies as more data becomes available.

Summary 

Current data suggest that similar to the general population, age, and comorbidities are risk factors for poorer COVID-19 outcomes in patients with IMID. Additional research is needed to quantify outcomes and risk across rheumatic disease types, comorbidities, and immunosuppressive drugs.
