Abstract: Systemic autoinflammatory diseases （SAIDs） affect various organ systems throughout the body. The expanding spectrum of these diseases， along with new classifications， increased heterogeneity of phenotypes， and research into genetic mechanisms has advanced our understanding of basic science theories with improved precision diagnosis and treatment. Because these diseases affect multiple organs or systems， pediatricians across different specialties are required to enhance their knowledge and attention in this field.

Key words: systemic autoinflammatory diseases, child, precision diagnosis and treatment, progress

摘要： 系统性自身炎症性疾病（systemic autoinflammatory diseases， SAIDs）累及全身各个器官系统，其疾病谱的不断扩大，新的疾病分类、表型的异质性增加以及遗传机制的研究推动了基础理论的认识及精准诊疗水平的提升。因为涉及到全身多个器官或系统，所以要求不同专业的儿科医生均应提高对该领域的认识和关注。
