目的 探讨中重度特应性皮炎儿童接受度普利尤单抗治疗及停药后皮肤微生物组的变化。 方法 共纳入24例儿童AD患者和10例儿童健康志愿者。AD患者使用度普利尤单抗治疗16周,观察至第28周。在治疗开始前和治疗后对患者进行严重程度评估(包括湿疹面积和严重程度指数、个体体征评分、儿童皮肤病生活质量指数、患者湿疹自我评价量表以及峰值瘙痒数字评定量表)。分别在健康志愿者、AD患者基线期、度普利尤单抗治疗期(第2、4、8、12和16周)及停药期(第22和28周)采集皮肤样本,进行16s rRNA测序分析。 结果 度普利尤单抗显著改善了AD的各项指标。16S rRNA测序结果显示,金黄色葡萄球菌丰度降低,微生物多样性升高。停药后,这些变化开始逆转,并与EASI评分再度升高的趋势一致。此外,聚集杆菌、巨球菌属等菌属治疗后减少,停药后升高,提示持续用药才能维持疗效。 结论 本研究揭示了儿童特应性皮炎患者在接受度普利尤单抗治疗期间及停药后皮肤细菌群落的动态变化模式。度普利尤单抗能调节的细菌范围可能更广;候选微生物分类群的作用仍需进一步探讨。
