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
