目的 探讨度普利尤单抗对瘙痒性皮肤病的效果及对嗜酸粒细胞（EOS）恢复和生活质量的影响。方法 选取2021年2月—2022年1月期间,我院收治的瘙痒性皮肤病患者96例。根据治疗方式不同分为对照组（48例）和观察组（48例）。对照组给予传统激素治疗,观察组给予度普利尤单抗治疗。比较治疗前后2组血清炎症因子、免疫球蛋白水平情况;比较治疗前后2组症状积分下降指数（SSRI 评分）、神经激肽/速激肽受体1（NK1R）及EOS情况。观察2组疗效情况。采用皮肤病生活质量问卷（DLQI）对2组生活质量进行评价,并观察2组复发率情况。结果 治疗后,2组血清IFN-γ（干扰素-γ）、IL-2（白介素2）、IgA、IgG、IgM、NK1R、EOS水平升高,IL-4、IL-13、IgE水平及SSRI 评分降低,且观察组更明显（P<0.05）。观察组治疗有效率高于对照组（P<0.05）。随访6个月,观察组DLQI评分及复发率低于对照组（P<0.05）。结论 度普利尤单抗可减轻瘙痒性皮肤病患者瘙痒症状,增强机体防御力,促进嗜酸粒细胞恢复,提高其生活质量,值得临床推广应用。

Objective To investigate the effect of Dupilumab on pruritic dermatosis,eosinophil（EOS）recovery and quality of life．Methods From February 2021 to January 2022,96 patients with pruritic dermatosis were selected．According to different treatment methods,they were divided into control group（48 cases）and observation group（48 cases）．The control group was treated with traditional hormone,and the observation group was treated with Dupilumab．The levels of serum inflammatory factors and immunoglobulin in the two groups were compared before and after treatment．The symptom score reduce index（SSRI score）,neurokinin/tachykinin receptor 1（NK1R）and EOS were compared between the two groups before and after treatment．The curative effect of the two groups was observed．The quality of life of the two groups was evaluated with Dermatology Quality of Life Questionnaire（DLQI）,and the recurrence rate of the two groups was observed．Results After treatment,levels of serum IFN-γ,IL-2,IgA,IgG,IgM,NK1R and EOS of two groups increased,while the levels of IL-4,IL-13,IgE and SSRI scores decreased,especially in the observation group（P<0.05）．The effective rate of the observation group was higher than that of the control group（P<0.05）．The DLQI score and recurrence rate in the observation group were lower than those in the control group（P<0.05）in 6 months follow-up．Conclusions Dupilumab can alleviate the itching symptoms of patients with pruritic dermatosis,enhance the body's defense,promote eosinophil recovery,and improve their quality of life,which is worthy of clinical application．
