COVID-19 and autoimmune bullous diseases: Lessons learned.

Both COVID-19 and autoimmune bullous diseases represent potentially life-threatening conditions. Autoimmunity has been a special focus during the COVID-19 pandemic considering the possible detrimental mutual influence between COVID-19 and autoimmune disorders as well as their supposed induction or triggering by SARS-CoV-2 vaccines. There is a growing need to assess the impact of the current pandemic particularly in patients with autoimmune bullous diseases requiring potent and long-term immunosuppressive treatments. This review provides the relevant state-of-the-art knowledge, including our own research, about immunobullous diseases in relation to COVID-19 and summarizes expert perspectives on their management throughout the pandemic.
