Abstract: With the in-depth research on atopic dermatitis（AD）， it is now believed that AD is no longer a simple skin disease， but a systemic disease. Therefore， it is necessary to constantly update epidemiological data to enhance the importance of the disease， improve the study of disease burden and rationally allocate medical resources to better alleviate the patient's disease， and improve the efficacy of treatment and quality of life through effective patient education. This article reviews the relevant literature published in recent years， aiming to raise the attention of clinicians with a hope that more medical resources will be devoted to research， so as to further improve the treatment mode of AD.

Key words: atopic dermatitis, burden of disease, epidemiology

摘要： 随着对特应性皮炎（atopic dermatitis，AD）研究的深入，目前认为其不再是一个单纯的皮肤疾病，而是一种系统性疾病。故需要不断更新流行病学数据，加强对AD的重视，完善疾病负担研究，合理配置医疗资源，更好地减轻患者病痛，通过有效的患者教育提高治疗效果、改善患者生活质量。该文综述了近年发表的相关文献，旨在提高临床医师重视，希望有更多医疗资源投入研究，从而进一步完善AD的诊疗模式。
