Rheumatic manifestations and autoimmunity associated with COVID-19

A broad spectrum of complications following COVID-19 has been documented in adults, including the new onset of autoimmune-related manifestations and rheumatic diseases. Numerous case studies, reviews, and clinical trials have been published regarding the relationship between COVID-19 and the generation of autoantibodies that may cause rheumatic and autoimmune diseases. The currently suggested pathophysiology that leads to the new onset of such disorders may include well-established mechanisms, such as molecular mimicry and hyperstimulation of the immune system. The prevailing conditions documented following COVID-19 include, yet are not limited to, rheumatoid arthritis, myositis, antiphospholipid antibodies, ITP, and thyroid dysfunction. This chapter will summarize the current documentation of the broad-spectrum rheumatic diseases and autoimmune manifestations mediated by a SARS-CoV-2 infection.
