Rheumatoid arthritis and post-COVID-19 syndrome

Abstract

In the third year of the SARS-CoV-2 (severe acute respiratory syndrome coronavirus-2, COVID-19) pandemic doctors are encountering a new pathology – post-COVID-19 syndrome (PCS, long covid). Musculoskeletal manifestations are among the most common and may present as myalgia, arthralgia, or arthritis. Currently, there is no generally accepted definition of the disease, its duration, classification, or diagnostic criteria, and no single view on the “content” of musculoskeletal manifestations of PCS. We have enough descriptions of the debut of rheumatoid arthritis (RA) after SARS-CoV-2. That is a question: it is a coincidence, or COVID-19 may be a trigger factor of RA? We thought that SARS-CoV-2 infection may be a trigger factor for new rheumatic musculoskeletal diseases, including rheumatoid arthritis or COVID-19 can unmask previously undetected RA. The occurrence of arthritis may be a sign of PCS with transient character. So arthritis in the post covid period may induce problems in differential diagnosis of rheumatic diseases.
