Antibody Responses to Epstein-Barr Virus in the Preclinical Period of Rheumatoid Arthritis Suggest the Presence of Increased Viral Reactivation Cycles.

ABSTRACT:

Objective

Patients with established rheumatoid arthritis (RA) demonstrate altered immune responses to Epstein-Barr virus (EBV), but the presence and roles of EBV have not been fully explored during the pre-clinical disease period. This study was undertaken to determine if EBV infection, as evidenced by an altered anti-EBV antibody response, either plays an important role in driving the development of RA or is a result of expanded RA-related autoimmunity.

Methods

A total of 83 subjects with RA according to the 1987 American College of Rheumatology (ACR) criteria and 83 age-, sex-, and race-matched control subjects without RA were included in our study. We collected sera from RA subjects and matched controls during the pre-RA and post-RA diagnosis periods and tested the sera f
