Autoimmune Diseases Induced or Exacerbated by COVID-19: A Single Center Experience.

The association between infectious diseases and autoimmunity has long been reported. Specifically, during the coronavirus disease 2019 (COVID-19) pandemic, this relation was further emphasized. The interplay between the two disease processes remains interesting, yet incompletely defined. Herein, we report a case series of six patients presenting with autoimmune phenomena first developed or exacerbated following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We describe the disease course and discuss the possible mechanisms underlying the association between autoimmunity and COVID-19.
