摘要

摘要：【目的】局部免疫法治疗重型斑秃在国外的使用历史已逾30年，但国内尚未广泛开展，本研究旨在分析该法治疗中国重型斑秃患者的疗效及初步探讨作用机制。【方法】对63例斑秃患者进行二苯环丙烯酮局部免疫治疗。治疗前进行皮肤镜、实验室、病理检查，治疗过程中对血常规、总IgE进行监测并复查部分患者头皮病理。同时检测21名患者治疗前后血清细胞因子浓度，并征集正常对照13人，年龄性别与斑秃组相匹配。【结果】本组患者总有效率为61.0%，疗效仅与脱发面积成负相关，即面积越小，疗效越好，而与其它临床资料无相关关系。相比有效组，严重副作用组治疗前血清IgE浓度较高。经治疗后真皮浅层血管周围单个核细胞浸润明显增多。患者血清Th1型细胞因子IFN-γ、IL-12在治疗前较正常对照高，经治疗后有效组明显降低，与正常对照无差异，而无效组IFN-γ未降低，IL-12水平反而较治疗前升高。Th2 型细胞因子IL-4在无效组治疗前后均高于正常组，IL-10均低于正常组，而在有效组该两种因子治疗前与正常无差异，治疗后升高，且高于正常水平。【结论】局部免疫法可用于治疗重型斑秃，疗效较确切，且相对较安全。治疗前进行IgE测定可初步预示治疗过程中炎症反应过强者，而IL-4升高可能提示对局部免疫疗法无效。治疗后有效组Th1 型细胞因子的表达减少，恢复了原有Th1 与Th2细胞因子的平衡状态，使毛囊从休止期重新进入生长期，达到毛发生长的治疗效果。

Abstract

Abstract：【Objective】This study aims to investigate the therapeutic effect of topical immunotherapy in Chinese patients and to explore the mechanism. 【Methods】 Detailed clinical data in 63 patients enrolled in this study were recorded. Laboratory blood tests

serum IgE level

scalp tissue biopsies were carried out pre- and post-treatment. In the course of treatment

global photographic views and dermoscopic features were analyzed to monitor the process of hair growth. Cytokine levels were measured in 13 healthy controls and 21 patients pre- and post-treatment. 【Results】The respond rate to treatment was 61.0%. Effectiveness of treatment did not correlate with any of clinical features

except that it correlated negatively with hair loss area. Pre-treatment serum IgE level was significantly higher in adverse-effects group than in responders group. Compared with pre-treatment

perivascular mononuclear cell infiltration in superficial dermis was significantly increased after treatment. It was also noted that

prior to treatment

alopecic patients had a remarkably higher serum level of Th1 cytokine such as IFN-γ and IL-12 when compared to healthy controls. Post-treatment levels of IFN-γ and IL-12 were significantly decreased

but levels of IL-4 and IL-10 were increased in the responder group

different from that in the non-responder group. In the non-responder group after treatment

IFN-γ level was not significantly decreased and an increase of IL-12 level was even found as compared to pre-treatment levels. Also

serum level of IL-4 was higher and IL-10 was lower than normal controls both pre- and post-treatment. 【Conclusions】 Topical immunotherapy treatment is an effective way to treat severe AA patients and it is relatively safe. Pre-treatment serum IgE level can be used as a prognostic marker of treatment intolerance. Also

high level of IL-4 at pre-treatment may be a valuable indicator for non-responder. Mechanism of action can be interpreted as restoration of the immunological balance by decreasing Th1 cytokine levels and increasing Th2 cytokine levels. Thus

the newly formed cytokine milieu is crucial in promoting entry of hair follicles into anagen stage which results in hair regrowth.
