A review of the presentation and outcome of sarcoidosis in coronavirus disease 2019.

BACKGROUND

In the setting of the current pandemic, concerns have arisen regarding the multisystemic involvement of sarcoidosis and the possible exacerbations in response to the exposure to severe acute respiratory syndrome coronavirus 2.

AIM

This study aims to compare the differences in clinical presentation, management, and outcome of coronavirus disease 2019 (COVID-19) between patients with sarcoidosis and those in the general population.

METHODS

A literature search was conducted by reviewing original research articles such as case reports, case series, observational studies, and questionnaire-based surveys published in PubMed/Medline, Web of Science, and Google scholar. Data from individual patients in case series and case reports have been pooled to create a data set that was compared with larger such cohorts obtained from several other observational studies.

RESULTS

Twenty-seven patients were identified from 14 original articles. No significant differences were found in the clinical manifestations of patients with sarcoidosis presenting with COVID-19 as compared to the general population. The rate of hospitalization in our study was found to be 48.1%. The overall mortality in our study was 7.4%, which is higher than the global average of 2.1%.

CONCLUSION

Our observations have reinforced the hypothesis that the presence of additional medical comorbidities is associated with a higher risk of intensive care unit admission. Furthermore, the presence of moderate to a severe limitation in pulmonary functions is an additional risk factor associated with increased hospital admissions and mortality in sarcoidosis. However, neither the diagnosis of sarcoidosis nor ongoing treatment with steroids, methotrexate, or other immunosuppressants was associated with a poorer prognosis in patients with sarcoidosis.

RELEVANCE FOR PATIENTS

Patients with sarcoidosis must take added precautions to mitigate the risk of acquiring COVID-19 infection in view of the COVID-19-related mortality rate in this group of patients. Specifically, immunocompromised patients (on immunomodulator drugs and high dose steroids) have been found to have an increased risk of contracting COVID-19. Overall impact on prognostication and outcome in cases requiring hospitalization remains yet to be determined.
