AB0473 Evaluation of anti-TNF levels and anti-TNF antibodies in rheumatic diseases treated with infliximab and adalimumab; results from a local registry:
Abstract:Objectives
To analyse the clinical relevance of serum levels of infliximab (INF) and adalimumab (ADA) and the production of anti-INF (INF-Abs) or anti-ADA antibodies (ADA-Abs) from a local registry of patients with rheumatic diseases on treatment with INF or ADA.
