From page 22 of the prescribing information for Enbrel:   AutoimmunityTreatment with ENBREL® may result in the formation of autoantibodies (see ADVERSE REACTIONS: Autoantibodies) and, rarely, in the development of a lupus-like syndrome or autoimmune hepatitis (see ADVERSE REACTIONS: Adverse Reaction Information from Spontaneous Reports), which may resolve following withdrawal of ENBREL®. If a patient develops symptoms and findings suggestive of a lupus-like syndrome or autoimmune hepatitis following treatment with ENBREL®, treatment should be discontinued and the patient should be carefully evaluated.   You can find this information on the Enbrel site, http://www.enbrel.com/pdf/enbrel_pi.pdf.   Sorry, Teri
