[Treatment of ankylosing spondylitis with anti-TNFalpha agents].

Non steroidal antiinflammatory drugs (NSAID) used to be the only drugs active in ankylosing spondylarthritis (AS). However, they are inadequate or ill-tolerated in many patients, and have no proven impact on disease-related structural changes. Clinical trials have recently shown the impressive efficacy of two anti-TNFalpha agents (infliximab and etanercept) in patients with NSAID-resistant SA.
