Acute and recurring pericarditis. a singular case of overlap syndrome with autoimmune diseases

Autoimmune disorders are responsible for a substantial amount of disability and morbidity. Most of the identified autoantibodies are shared among multiple autoimmune diseases. The pattern of these antibodies’ association with autoimmune phenotypes varies, suggesting that certain subgroups of autoimmune diseases are likely to share etiological similarities and underlying mechanisms of disease. In this article, we present a clinical case of acute and recurring pericarditis and we propose an overlap phenotype with Sjögren’s syndrome (SS) and rheumatoid arthritis (RA) with interesting implications in clinical management of patient.
