ABSTRACT

Psoriatic arthritis (PsA) is a chronic and inflammatory arthropathy that may permanently damage joints. Nowadays it is reported that anti-TNF agents have good results in patients with inefficient response to conventional treatments. However, treatment with anti-TNF drugs is still problematic in patients who are resistant to or have any contraindications under treatment. In this group of patients, non-TNF biologic agents are started being used in daily practice. In this paper, we aimed to present three patients who had PsA diagnosis and abatacept treatment and to review the literature on this subject.
