Clin Exp Allergy:桦树花粉过敏皮下免疫治疗的效果和安全性评价

2019-01-03 AlexYang MedSci原创

之前的桦树花粉皮下免疫治疗的临床试验一般进行1-2年的治疗周期,并且地理位置经常是单一的。最近,有研究人员在19个欧洲中心进行了为期3年的研究,他们评估了高剂量低致敏性桦树花粉过敏原皮下免疫治疗对那些确诊患有中度到重度季节过敏性鼻炎/鼻窦炎患者的治疗效果。研究包括了253名桦树花粉过敏患者,并随机分配到季节前安慰剂组(n=129)和积极治疗组(n=124)。研究发现,积极治疗vs安慰剂治疗患者的症

之前的桦树花粉皮下免疫治疗的临床试验一般进行1-2年的治疗周期,并且地理位置经常是单一的。最近,有研究人员在19个欧洲中心进行了为期3年的研究,他们评估了高剂量低致敏性桦树花粉过敏原皮下免疫治疗对那些确诊患有中度到重度季节过敏性鼻炎/鼻窦炎患者的治疗效果。

研究包括了253名桦树花粉过敏患者,并随机分配到季节前安慰剂组(n=129)和积极治疗组(n=124)。研究发现,积极治疗vs安慰剂治疗患者的症状药物评分变化表现出了一个积极的倾向,尽管没有显著性。2007年评估主要终点的时间与研究期间最低授粉时间重合。在东北区域(在该区域桦树是主要的树种)的亚群分析中(n=102),患者的对桦树花粉的接触更多,在积极治疗组中,症状药物评分(32.7%减少, p=0.0034)和无症状天数均值(p=0.0232)均得到了显著的改善。在第3年开放标签治疗中,积极治疗患者的症状药物评分均值减少,尽管花粉数量有所增加。皮下免疫治疗具有很好耐受性,且与已知的安全性评估一致。

最后,研究人员指出,证明桦树花粉皮下免疫治疗的效果仍旧有挑战性,原因是在实地研究中,有太多的因素影响桦树花粉的接触。
