Systemic lupus erythematosus (SLE) is a complex multifactorial autoimmune disease depending on both intrinsic and environmental factors. Among the latter, the Epstein-Barr Virus (EBV) has long been suggested as one of the responsible factors for the onset and activity of lupus disease. ⋯ Also, there are abnormalities in humoral and cellular responses to EBV and lupus patients have impaired control of EBV, with higher blood viral loads. Interstingly, this virus seems to be able to promote disease activity, by promoting the survival of autoreactive B lymphocytes and the production of interferon-α, which are two pivotal mechanisms in the pathophysiology of lupus disease.
