Guideline for the diagnosis and treatment of psoriasis arthropathica (psoriatic arthritis) in China (2026 edition)

Psoriasis arthropathica, also known as psoriatic arthritis (PsA), is a highly heterogeneous systemic inflammatory disease. In addition to involving the skin with characteristic psoriatic lesions such as erythematous scaly plaques, it may also affect the joints, leading to joint pain, swelling, stiffness, and functional impairment, thereby substantially reducing patients' quality of life. To develop clinical practice guidelines that align with international standards for guideline development while reflecting Chinese clinical practice, the China Dermatologist Association, in collaboration with the Chinese Dermatovenerology Society of Integrative Medicine, initiated a guideline project focusing on 14 key clinical questions in the diagnosis and management of PsA in China. Evidence-based recommendations were formulated accordingly. This guideline systematically reviews recent domestic and international advances in the diagnosis and treatment of PsA, and covers diagnosis, disease activity assessment, therapeutic strategies, comorbidity management, and pharmacotherapy in special populations. The guideline aims to improve the overall standard of PsA diagnosis and management in China and ultimately enhance patient outcomes.

关节病型银屑病亦称银屑病关节炎（PsA），是一种临床异质性较强的系统性炎症性疾病，其不仅累及皮肤，出现红斑鳞屑等特征性银屑病皮损，还可侵犯关节，引发关节疼痛、肿胀、僵硬及功能障碍，严重影响患者生活质量。为制订符合国际指南制订标准与中国临床实践的诊疗指南，中国医师协会皮肤科医师分会联合中国中西医结合学会皮肤性病专业委员会发起，围绕我国PsA诊疗中的14个关键临床问题，形成了基于循证医学的推荐意见。本指南系统梳理了国内外PsA诊疗进展，涵盖疾病诊断、病情评估、治疗策略、共病管理及特殊人群用药等多个方面，旨在提高我国PsA的整体诊疗水平，改善患者预后。.
