目的：分析舌下含服尘螨滴剂治疗变应性鼻炎（AR）停药1年后的疗效及相关影响因素。方法：收集武汉大学人民医院2007-06-2011-12期间收治的87例诊断明确的粉尘螨过敏AR患者。以症状评分为标准,用有效与无效来评估疗效,用Logistic回归分析舌下免疫治疗的疗效及相关影响因素。结果：在87例患者中,治疗有效率为54.0%（47/87）;坚持用药1年的患者有36例,依从率为41.4%;共7例出现不良反应（均为Ⅰ级）。Logistic回归分析显示,疗效与用药时间有关（P〈0.05）,与性别、年龄无关（P〉0.05）。治疗时间〈3个月者有效率为41.9%,3~12个月者有效率为70.0%,〉12~18个月者有效率为37.5%,〉18个月者有效率为70.0%。结论：粉尘螨滴剂的长期疗效与治疗时间呈正相关,但治疗12~18个月时会有反复现象;医生应督促患者坚持治疗并及时处理并发症,从而有效提高有效率和改善患者的生活质量。

The effect of sublingual immunotherapy and its related factors were evaluated by the symptoms and signs. The data was analysed by Logistic regression. Result：The response rate of samples is 54.0%. There are 36 patient having been treating over one year, the compliance rate is 41.4 %. By using logistic regression results are as follows. The efficacy is related with treatment time（P〈0.05） ,not are gender and age（P〉0.05）. When treat- ment time is less than 3 months,the validity is 41.9%. The validity of 3--12 months is 70.0% ,The one of 〉12- 18 months is 37.5 %, The one of more than 18 months is 70.0 %. Conclusion：The long-term efficacy of dust mites drops is positive correlation with time. But in 12-18 months condition can be waving.
