Systemic lupus erythematosus (SLE) is a severe autoimmune disease with rare remission and recurrent flare. Epstein-Barr virus (EBV) infection has been reported to be strongly associated with SLE in the United States, but with an inconclusive role in Asia. We investigated the role of EBV infection in patients with SLE in Taiwan, with one of the highest population densities in Asia. ⋯ This is the first evidence that IgA antibody against EBV-VCA is strongly associated with disease flare in SLE patients. It suggests that EBV reactivation may contribute toward the disease flare of SLE.
