[Recommendations for diagnosis and treatment of psoriatic arthritis in China].

Psoriatic arthritis is a chronic systemic autoimmune disease, characterized by psoriasis skin lesions and inflammation of the spine and joint. It has complicated clinical manifestations and individual variations. Nearly half of the patients will have joints erosion in two years, which is crippling. The severity of the skin and joint disease frequently do not correlate with each other. Currently, the understanding of the disease is insufficient in China with the lack of standardized diagnosis and treatment. Therefore, researchers from the Chinese Rheumatology Association formulated this specification based on the diagnosis and management experience together with guidelines at home and abroad. The specification summarizes the present situation of domestic diagnosis and treatment, aiming to standardize the diagnosis process and treatment protocols of psoriatic arthritis. Furthermore, it can reduce misdiagnosis and missed diagnosis, as well as improve the prognosis.银屑病关节炎是一种以累及脊柱和/或外周关节为主的银屑病相关的慢性进展性炎性关节炎。其临床表现复杂，具有显著的异质性，近50%的患者可在诊断2年内出现关节的侵蚀破坏，是一种致残性疾病。目前，我国对该病的认识不足，规范化诊治的普及依然欠缺。中华医学会风湿病学分会在借鉴国内外治疗指南和诊治经验的基础上，结合我国现状制定了本规范，旨在规范银屑病关节炎的诊断与治疗，减少误诊和漏诊，改善患者的预后。.
