核心结论
目前各主要指南均未将"发热满5日"作为静脉注射免疫球蛋白(IVIG)的治疗前提。"发热超过5 d"是经典川崎病病例定义中的一项条件,用于保证诊断特异性;静脉注射免疫球蛋白的治疗指征是川崎病诊断的确立。美国心脏协会(AHA)2017年声明的表述为"发病10 d内、确诊后尽早(as soon as possible after diagnosis)",为Ⅰ类推荐、证据水平A。
其二,来自治疗推荐中的给药时间窗表述。中国2023年指南推荐"最好在发病5~7 d内给予IVIG",AHA 2024年声明的表述为"理想第4~5日(ideally at 4 to 5 days of illness)"。此类表述是对"何时给药冠状动脉结局最优"的经验概括,其方向为约束延迟治疗:越接近该时间窗越好,超过则风险上升。同一声明同时规定,发病10 d以后若炎症持续(CRP>3.0 mg/dL)仍应给予治疗。对超过10 d均不作为绝对界限的时间窗,不构成对发病第4日给药的限制。

三、指南原文对照
以下截图均取自各指南官方在线版或期刊PDF,红框与紫色高亮为本文所加,原文未作改动。
(一)AHA 2024年科学声明(Circulation 2024;150:e481-e500)
诊断节原文连续两句:
"Diagnosis of KD can be made with 4 days of fever when ≥4 principal clinical criteria are present. Experienced clinicians may establish the diagnosis earlier, at 3 days of fever."
即:≥4项主要临床特征时,发热4 d即可诊断;有经验的医师可提前至发热3 d诊断。注:《World J Pediatr》2025年述评将该句转述为"five days of fever",与AHA 2024年声明正式发表文本"4 days"不一致;查该声明2025年两份勘误均未涉及此句(详见下图图注),应以Circulation在线版为准。
"It is imperative to diagnose KD within 10 days of fever onset, ideally at 4 to 5 days of illness for patients with complete KD, and as soon as possible and within 10 days of fever onset for patients with a possible diagnosis of incomplete KD."
"ideally at 4 to 5 days"的方向为"不应迟于发病第4~5日",而非"不应早于发病第5日";对不完全型川崎病同样要求"尽早、10 d内"。
"…should be treated with high-dose IVIG (2 g/kg given as a single intravenous infusion) within 10 days of illness onset but as soon as possible after diagnosis (Class I; Level of Evidence A)."
《World Journal of Pediatrics》2025年述评(浙江大学医学院附属儿童医院团队)对该修订版的转述如下:
"Revision of Diagnostic Guidelines for Kawasaki Disease (6th revised edition) … no longer emphasizes that fever must persist for longer than five days, but rather highlights a comprehensive assessment of clinical presentations. The number of days of fever is not the most important diagnostic criterion."
