title: [Psoriatic arthritis and etanercept].
abstract: Psoriatic arthritis (PA) is a chronic inflammatory condition whose symptoms generally appear after the skin symptoms. Making an early diagnosis and treatment of the disease is of vital importance because of the potential development of mutilating and deforming arthritis. Classical treatments of PA include the use of non-steroid anti-inflammatory drugs, disease-modifying antirheumatic drugs (DMARD) such as methotrexate, sulfasalazine, or gold, and finally, leflunomide. Research on the pathophysiology of psoriasis and of the PA has led to the incorporation of biological treatments, specifically anti-TNF drugs. The three treatments used most in PA are etanercept, infliximab and adalimumab. Of all these, we are going to make a systematic review of the principal studies available on etanercept for the treatment of PA.
