Data on the clinical presentation and outcomes of sarcoidosis patients with coronavirus disease 19 (COVID-19) are scarce. In this case series, we identified 5 out of 238 sarcoidosis patients who are enrolled in an ongoing longitudinal observational study who developed COVID-19 during the study period and follow their clinical course. Four patients recovered completely, whereas one patient expired during hospital admission. Our preliminary experience suggests that African American patients with chronic sarcoidosis treated with disease-modifying anti-rheumatic drugs (DMARDs) or anti-tumor necrosis factor (TNF) therapy do not seem to be at increased risk of respiratory or life-threatening complications from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) compared with the general population, although at the present time, we advocate for maintaining a high level of vigilance and strict follow-up in this patient population.
Sarcoidosis is an immune mediated chronic inflammatory disorder that is best characterized by non-caseating granulomas found in one or more affected organs. The COVID-19 pandemic poses a challenge for clinicians caring for sarcoidosis patients who may be at increased risk of infection compared to the general population. With the recent availability of COVID-19 vaccines, it is expected that clinicians raise questions regarding efficacy and safety in sarcoidosis. However, studies examining safety and efficacy of vaccines in sarcoidosis are lacking. In this review, we examine the current literature regarding vaccination in immunocompromised populations and apply them to sarcoidosis patients. The available literature suggests that vaccines are safe and effective in patients with autoimmune disorders and in those taking immunosuppressive medications. We strongly recommend the administration of COVID-19 vaccines in patients with sarcoidosis. We also present a clinical decision algorithm to provide guidance on vaccination of sarcoidosis patients against COVID-19.
Purpose of reviewSarcoidosis is a poorly understood multisystem granulomatous disease that frequently involves the lungs but can affect any organ system. In this review, we summarize recent developments in the understanding of the immune dysregulation seen in sarcoidosis and propose a new expanded definition of human autoimmunity in sarcoidosis, and the implications it would have on treating sarcoidosis with targeted immunotherapy regimens in the future. Recent findingsSarcoidosis has been linked to infectious organisms like Mycobacterium and Cutibacterium, and certain manifestations of sarcoidosis have been linked to specific HLA alleles, but the overall pathogenesis remains uncertain. Sarcoidosis patients have similar patterns of cellular immune dysregulation seen in other autoimmune diseases like rheumatoid arthritis, and recent large-scale population studies show that sarcoidosis frequently presents with other autoimmune diseases. SummaryAdvancements in the understanding of sarcoidosis support its consideration as an autoimmune disease. Sarcoidosis patients carry a higher risk of comorbid autoimmune conditions which offers an excellent opportunity to further understand autoimmunity and explore biologic therapies in sarcoidosis treatment, and furthermore will better targeted immunotherapy regimens for sarcoidosis patients in the future.
Purpose of reviewPatients with sarcoidosis may be at higher risk of coronavirus disease-19 (COVID-19) as over 90% of the patients have pulmonary involvement and many are treated with immunosuppressive agents. This review will summarize the current literature regarding sarcoidosis and COVID-19, with a particular focus on susceptibility, clinical outcomes, management, and approach to vaccination. Recent findingsData about COVID-19 and sarcoidosis include a number of case series and reports, cohort studies, and registries. Literature is not conclusive whether patients with sarcoidosis have increased susceptibility to COVID-19. Patients with moderate to severe impaired pulmonary function may be at increased risk of adverse outcomes and mortality. Whether immunosuppressive medication increases risk of COVID-19 severity or affects vaccination response is not yet clear. Novel approaches, such as telemedicine and home monitoring programs, are promising to ensure continuity of care for patients with sarcoidosis during the COVID-19 pandemic.
Purpose of review Patients on chronic immunosuppressive treatments at baseline are at increased risk of opportunistic infections. These patients are at especially increased risk of morbidity and mortality during the coronavirus-19 (COVID-19) pandemic. This review will focus on patients with diseases in which immunosuppression is a vital part of the treatment regimen, including those with solid organ transplants, rheumatologic disorders, sarcoidosis, and inflammatory bowel disease (IBD). We will summarize the current knowledge of immunosuppression in these diseases and the risk of contracting COVID-19. Furthermore, we will discuss if immunosuppression increases severity of COVID-19 presentation. Recent findings Since the start of the COVID-19 pandemic, a large number patients receiving chronic immunosuppression have been infected with SARS-CoV-2. Moreover, our understanding of the immunology of SARS-CoV-2 is advancing at a rapid pace. Currently, a number of clinical trials are underway to investigate the role of immunosuppressive treatments in the management of this disease. Summary Currently, there is no conclusive evidence to suggest that solid organ transplant recipients on chronic immunosuppression are at increased risk of contracting COVID-19. Solid organ transplant recipients may be at increased risk for worse COVID-19 outcomes but the data are not consistent. There is evidence to suggest that patients with rheumatologic disorders or IBDs are not at increased risk of contracting COVID-19 and do not necessarily experience worse clinical outcomes. Patients with sarcoidosis are not necessarily at increased risk of COVID-19, although there is limited data available to determine if immunosuppression worsens outcomes in this population.
