摘要: 目的:评估舌下含服标准化粉尘螨滴剂治疗变应性鼻炎(AR)伴过敏性哮喘的疗效及其经济性。方法:回顾性分析203例4~60岁尘螨过敏的AR伴过敏性哮喘患者的资料。203例患者中,86例接受标准化粉尘螨滴剂的舌下含服特异性免疫治疗(SLIT)和药物治疗(SLIT组);117例患者仅采用标准化药物治疗(单纯药物组)。每3个月随访1次,共随访2年。观察并记录患者治疗期间的鼻部症状评分、鼻炎药物评分、哮喘日间症状评分、哮喘夜间症状评分、哮喘药物评分以及治疗费用,并进行经济性分析。结果:2组患者治疗前鼻部症状评分、鼻部药物评分、哮喘日间症状评分、哮喘夜间症状评分、哮喘药物评分比较差异均无统计学意义(均P>0.05)。分别完成1年和2年的疗程后,SLIT组患者鼻部症状评分、鼻炎药物评分、哮喘日间症状评分、哮喘夜间症状评分、哮喘药物评分均显著低于单纯药物组,差异均有统计学意义(均P<0.01)。与治疗前比较,SLIT组患者治疗1年和治疗2年症状评分和药物评分显著降低,差异均有统计学意义(均P<0.01)。治疗费用方面,尽管SLIT组的直接费用稍高于单纯药物组,但其间接费用明显低于单纯药物组,差异有统计学意义(P<0.01)。结论:舌下含服粉尘螨滴剂对AR伴过敏性哮喘具有良好的疗效,且能够降低患者的间接治疗费用。Abstract: Objective: To evaluate the efficacy and economics of sublingual immunotherapy (SLIT) with Dermatophagoides farinae drops in patients with allergic rhinitis and allergic asthma.Method: Two hundred and three patients(aged 4-60 yr) with allergic rhinitis and allergic asthma induced by house dust mites were retrospectively analyzed. Eighty-six patients were treated by SLIT with standardized Dermatophagoides farina drops and pharmacotherapy(SLIT group), while 117 patients were treated by standardized pharmacotherapy(drug group). Patients were followed up for 2 years with one visit in every 3 months. Total nasal syptom score(TNSS), total rhinitis medicine score(TRMS), daytime asthma syptom score(DASS), nighttime asthma syptom score(NASS), total asthma medicine score(TAMS) and treatment charge were recorded at each visit.Result: There was no significant difference between two groups in TNSS, TRMS, DASS, NASS, TAMS before treatment(all P>0.05). After 1-year or 2-year duration, there were significant differences between the SLIT group and drug group in TNSS, TMSS, DASS,NASS, TAMS(all P<0.01). After 1-year or 2-year duration, the symptom scores and medication scores of SLIT group significantly decreased compared with those before treatment(all P<0.01). In terms of treatment charge, although direct cost of SLIT group was a little higher than that of drug group, the indirect cost of SLIT group was remarkably lower than that of drug group, showing significant difference(P<0.01).Conclusion: SLIT with Dermatophagoides farinae drops is effective in patients with allergic rhinitis and allergic asthma, which may also reduce indirect cost.
