Effect of sublingual dust mite drops on single or multiple allergens allergic rhinitis in children
-
摘要: 目的: 评估标准化尘螨滴剂舌下特异性免疫治疗(SLIT)对儿童变应性鼻炎的疗效。方法: 回顾性分析174例接受标准化粉尘螨滴剂进行SLIT 2年的患儿。按变应原种类分为单一尘螨过敏组(61例)和尘螨合并其他过敏组(113例)。通过比较治疗前后的症状评分、药物评分和炎症因子检测,进行疗效分析。结果: ①治疗前和治疗2年后患儿的症状评分:单一尘螨过敏组为(11.27±1.46)分和(3.48±1.50)分;尘螨合并其他过敏组为(11.54±1.50)分和(3.59±1.56)分;组内比较差异有统计学意义(P<0.01)。2组间症状评分,单一尘螨过敏组为(7.68±3.23)分,尘螨合并其他过敏组为(8.14±2.56)分,组间症状评分无明显差异(P>0.05)。②2组患儿治疗前后药物评分:单一尘螨过敏组为(1.67±0.43)分和(0.52±0.40)分,尘螨合并其他过敏组为(1.64±0.44)分和(0.55±0.41)分,组内比较差异有统计学意义(P<0.01);2组间药物评分单一尘螨过敏组为(1.16±0.61)分,尘螨合并其他过敏组为(1.28±0.55)分,组间症状评分差异无统计学意义(P>0.05)。③治疗后血清特异性IgG4均有增高(P<0.01)。④免疫治疗后降低了IL4、IL17α的高表达;升高了IL2、TGF-β1的低表达(P<0.05)。结论: 尘螨SLIT可以明显改善单一尘螨过敏和尘螨合并其他过敏患儿的鼻部症状,减少对症药物的使用,且2组疗效相当。尘螨SLIT不仅可以用于治疗单一尘螨过敏的患儿,也可以用于治疗尘螨合并其他过敏的患儿。尘螨血清特异性IgG4升高可以作为免疫治疗有效的预测指标。免疫治疗后可以恢复Thl/Th2/Th17和Treg平衡。Abstract: Objective: Evaluation of the efficacy of standardized dust mite drops in sublingual immunotherapy(SLIT) for allergic rhinitis in children.Method: A retrospective analysis of 174 children who received SLIT with standardized dermatophagoides farinae drops for 2 years. These patients had been divided into two groups:monoasensitized group(n=61) and polysensitized group(n=113). The total medication score(TMS), total nasal symptoms score(TNSS) and inflammatory factors were evaluated before and after SLIT treatment.Result: ①After SLIT treatment for 2.0 year, the TNSS in the monosensitized group is(11.27±1.46) and(3.48±1.50), polyasensitized group is (11.54±1.50) and (3.59±1.56), there are significant difference of TNSS between two groups(P<0.01). But the improvements of the TNSS between the two groups have no significant difference(P>0.05), the monosensitized group is(7.68±3.23); polysensitized group is (8.14±2.56). ②Two groups of children with TMS before and after treatment were obviously improved, monosensitized group is (1.67±0.43) and (0.52±0.40), polysensitized group is(1.64±0.44) and (0.55±0.41). There are significant difference of TMS between two groups(P<0.01). But the improvements of the TMS between the two groups have no obvious difference(P>0.05), the monsensitized group is(1.16±0.61); polysensitized group is(1.28±0.55).③Specific IgG4 serum is increased after treatment(P<0.01). ④After immunotherapy, the expression of IL4 and IL-17α is down-regulated, IL-2 and TGF-β1 is up-regulated.Conclusion: ①Dust mites under the SLIT, can significantly improve the monosensitized and polyasensitized allergic children nasal symptoms, reduce the drug use, and two groups have the equivalent effect. ②Dust mite drops SLIT, can be used to the monosensitized and polyasensitized allergic children. ③The rise of dust mites specific IgG4 can be used as immunotherapy effective predictors. ④After immunotherapy, Thl/Th2/Thl7 and Treg can be re-balanced.
