Introduction
Coronavirus disease 19 (COVID-19) is a viral infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). An increase in pro inflammatory cytokines ( IFN-γ, IL-1, IL-6, IL-12, and TNF-α) and chemokines ( CCL2, CXCL10, CXCL9, and IL-8) described as a cytokine storm or hyperinflammatory syndrome may develop during the course COVID‐19 (1).
Cases of autoimmune disorders presenting or exacerbating after SARS-Cov-2 infection have been reported (2). Herein, we report the first case of Rheumatoid arthritis occurring one month after COVID-19 infection.
