Can SARS‐CoV‐2 infection trigger rheumatoid arthritis? A case report

Inflammatory arthritis has been reported after SARS‐COV‐2 infection. We present a case of a 38‐year‐old female patient who developed polyarthralgia 1 month after SARS‐COV‐2 infection. Musculoskeletal examination was significant for synovitis of hands and wrists. Antinuclear antibody (ANA), rheumatoid factor (RF), and anti‐cyclic citrullinated peptide (CCP) antibodies were positive. Magnetic resonance imaging of the hands showed synovitis of the metacarpophalangeal joints and proximal interphalangeal joints of the hands, wrist joints, and tendinitis with tenosynovitis. The patient was diagnosed with seropositive nonerosive rheumatoid arthritis (RA) and initiated on therapy using nonsteroidal anti‐inflammatory agents and disease‐modifying anti‐rheumatic drug methotrexate leading to an improvement in symptoms.
