    Background: The mechanism of rheumatoid arthritis (RA) pathogenesis induction is unclear


    Recent studies have shown that mucosal surfaces play an important role in the early development of RA, especially in ACPA-positive disease


    The production of mucosal antibodies mainly involves the extracellular transport of immunoglobulin (Ig) A through the polyIg receptor (pIgR) located on the basolateral surface of epithelial cells


    Methods: Three groups of patients were studied: (1) ACPA-positive patients with musculoskeletal pain but not arthritis; (2) patients with recent onset rheumatoid arthritis (RA); (3) previous rheumatoid arthritis ( RA) patients


    Results: The serum levels of TsigA and TSIgM in early RA patients and high-risk RA patients were higher than those in healthy controls (P<0.


    The serum levels of TsigA and TSIgM in patients with early RA and high-risk RA were higher than those in healthy controls.


    Circulating secretory immunoglobulins were elevated both before and during the onset of RA
