目的探讨促肾上腺皮质激素(ACTH)治疗婴儿癫痫性痉挛综合征(IESS)疗效的影响因素及其预测指标。方法回顾性分析成都市妇女儿童中心医院2016年1月-2020年12月收治并给予ACTH治疗的80例IESS患儿(男50例,女30例)的临床资料。根据ACTH治疗28 d疗效分为有效组(n=39)与无效组(n=41),收集并比较两组的临床资料,包括患儿的基本信息、病因、治疗方案及治疗前后脑电图高度失律严重程度评分(即Kramer评分)等指标。构建修正Poisson回归模型以发现疗效预测因素,采用受试者工作特征(ROC)曲线评估阳性指标的预测价值。结果患儿起病年龄为1个月7 d~1岁9个月。发作形式包括单纯痉挛发作66例,合并其他发作如局灶发作、继发全面性发作14例。32例ACTH治疗前已给予抗癫痫发作药物(ASMs)治疗。治疗前、治疗后14 d的Kramer评分分别为10.0(8.3,12.0)分和6.0(4.0,7.0)分。经ACTH治疗后39例(48.8%)有效。与有效组比较,无效组中围产期存在异常、病因不明发育迟滞、ACTH治疗前已使用ASMs、ACTH给药剂量>2 U/(kg.d)、联合2种以上ASMs、治疗14 d时仍有发作的构成比高,且ACTH治疗14 d Kramer评分高,差异均具有统计学意义(P0.05)。ROC曲线分析显示,治疗14 d的Kramer评分对疗效有预测价值[曲线下面积(AUC)=0.930,95%CI 0.873~0.987,P<0.001],敏感度为92.7%,特异度为84.6%,约登指数为0.773,即治疗14 d Kramer评分越高,疗效越差,以6分为截点值,每升高1分,疗效降低接近30.0%。结论治疗前已使用ASMs可能会影响ACTH的疗效,治疗14 d后的Kramer评分≥6分或可作为ACTH治疗IESS疗效不佳的独立预测指标。
