摘　　要：目的评估凯普斯泰冷敷凝胶联合地奈德乳膏治疗儿童特应性皮炎(AD)的短期有效性和安全性。方法采用随机、双盲、对照研究,2019年11月至2020年9月收集就诊于四川大学华西医院皮肤科的儿童AD患者60例,最终56例完成随访,试验组和对照组各28例。试验组前3 d早晚外涂地奈德乳膏,中午外涂凯普斯泰冷敷凝胶,后11 d早中晚外涂凯普斯泰冷敷凝胶,对照组前3 d早晚外涂地奈德乳膏,中午外涂安慰剂,后11 d早中晚外涂安慰剂,治疗2周。分别于治疗前、治疗(7±3)d及治疗(14±3)d随访,记录湿疹面积及严重程度指数(EASI评分)、瘙痒视觉模拟评分法(VAS)评分、研究者总体评分(IGA评分)、皮肤生活质量评分(DLQI评分)等临床指标及不良反应。结果治疗1周时,试验组1例(3.57%),对照组1例(3.57%)有效;治疗2周时,试验组12例(42.86%)有效,对照组2例(7.14%)有效;经秩和检验,治疗1周和2周时两组疗效差异有统计学意义(Z=-4.318、-5.474,均P<0.05)。治疗前,试验组和对照组EASI、VAS、IGA、DLQI评分差异均无统计学意义(P>0.05);经非参数Friedman检验,两组EASI评分随治疗时间的变化差异具有统计学意义(χ2=45.720,P<0.05)。经两因素重复测量方差分析,治疗1周后,两组间VAS评分差异有统计学意义(F=10.738,P=0.002),IGA、DLQI评分差异无统计学意义(F=0.066、0.804,P=0.135、0.374);治疗2周后,两组间VAS、IGA、DLQI评分差异均有统计学意义(F=67.313、38.949、51.503,均P<0.001)。研究期间,试验组和对照组各发生1例不良反应事件,均表现为外用药物部位刺痛感或刺激感,两组不良事件发生率差异无统计学意义(P>0.05)。结论短期应用凯普斯泰冷敷凝胶联合地奈德乳膏可有效治疗儿童AD,且与安慰剂比较未增加不良反应的发生。Objective To evaluate short-term clinical efficacy and safety of a cooling gel containing calcium-based antimicrobial peptide compounds(CAPCS cooling gel)combined with desonide cream in the treatment of atopic dermatitis(AD)in children.Methods From November 2019 to September 2020,a randomized,double-blind controlled clinical trial was conducted in 60 children with AD enrolled from Department of Dermatology and Venereology,West China Hospital,Sichuan University.The 60 patients were randomly and equally divided into 2 groups:test group treated with topical desonide cream in the morning and evening as well as topical CAPCS cooling gel at noon during the first 3 days of treatment,followed by topical CAPCS cooling gel in the morning,at midday and in the evening for 11 days;control group treated with topical desonide cream in the morning and evening as well as topical CAPCS-free placebo gel at noon during the first 3 days of treatment,followed by topical CAPCS-free placebo gel in the morning,at midday and in the evening for 11 days.The treatment lasted 2 weeks.Finally,56 AD patients completed the follow-up,and 28 in each group were included into the following analysis.Clinical indices,such as eczema area and severity index(EASI),visual analogue scale(VAS),investigator′s global assessment(IGA)and dermatology life quality index(DLQI),were recorded before,7±3 days and 14±3 days after the treatment,so were adverse reactions.Results After 1-week treatment,1 patient in the test group and 1 in the control group showed response to the treatment,with the response rate being 3.57%in both groups;after 2-week treatment,12 patients in the test group and 2 in the control group showed response to the treatment,with response rates being 42.86%and 7.14%respectively;there were significant differences in the treatment outcomes between the two groups after 1-and 2-week treatment(Z=-4.318,-5.474,respectively,both P<0.05).There was no significant difference in the EASI,VAS,IGA or DLQI score between the two groups before treatment(all P>
