摘要: 【摘要】 斑秃的确切病因未明,部分患者反复发作。有证据显示过敏参与部分斑秃患者早发、重症、复发和迁延。尘螨过敏可能是部分重症斑秃患者尤其是儿童重症斑秃的病因之一,估计因为Th2型免疫反应占优势。脱敏可抑制Th2型免疫反应,改变机体免疫格局,降低斑秃复发时的病情严重程度。另外,斑秃治疗前高IgE水平可预测度普利尤单抗有效率较高,高白细胞介素(IL)-4水平可预示二苯环丙烯酮局部免疫疗法无效,因为该疗法通过拮抗Th1型反应而起作用。因此,血清总IgE、尘螨特异性IgE和IL-4可作为生物标志物,在斑秃患者中提示Th2型反应占优势。本文重点分析过敏与斑秃的关系、抗过敏和脱敏在治疗斑秃中的作用,旨在为斑秃的精准/个体化治疗提供思路。

Abstract: 【Abstract】 Alopecia areata (AA) is a common inflammatory and non-scarring hair loss condition with unknown pathogenesis, and relapses are common in some patients. Evidence has demonstrated that allergy takes part in the early onset, severe condition, recurrence, and prolonged process in AA. Allergy to dust mites may be one of the reasons for refractory severe AA, especially in childhood, possibly due to the predominance of T helper type 2 (Th2) immune response. Desensitization can suppress the Th2 immune response, alter the immune balance, and reduce disease severity during AA relapses. In addition, high IgE levels may predict favorable efficacy of dupilumab in AA patients before treatment, while high interleukin-4 levels may predict the ineffectiveness of topical immunotherapy with diphenylcyclopropenone, which works by antagonizing Th1 immune response. Therefore, serum total IgE, specific IgE to dust mites, and interleukin-4 can be considered as biomarkers, revealing the predominance of Th2 immune response in AA patients. This article focuses on the relationship between allergy and AA, as well as the role of anti-allergic reactions and desensitization in the treatment of AA, aiming to provide ideas for precise and individualized treatment of AA.
