[COVID-19 and autoimmune dysregulation: exploring common mechanisms and treatment strategies in interstitial lung disease].

ABSTRACT

COVID-19 is caused by the infection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and manifests primarily as acute lung injury with diffuse interstitial lung disease evident in imaging. Patients often present with clinical features similar to those of autoimmune diseases and share imaging, treatment and serological similarities with autoimmune-related interstitial lung diseases. The association between autoimmune abnormalities and post-COVID-19 pulmonary fibrosis is also recognized. This article provided a comprehensive review of the pathogenic mechanisms, clinical manifestations, and therapeutic interventions associated with autoimmune abnormalities induced by SARS-CoV-2 infection.
