Immunotherapy:单磷酰脂质A辅助的特异性免疫治疗在患有花粉过敏患者中的长期影响研究

2018-03-25 AlexYang MedSci原创

单磷酰脂质A辅助的超短疗程花粉免疫治疗(MPL)与传统的过敏原特异性免疫治疗(AIT)相比是具有吸引力的。然而,MPL-AIT的长期治疗效果还没有进行评估。最近,有研究人员在对花粉过敏的68名过敏性鼻炎患者中(年龄16.75 ±5.3岁 )进行了调查。研究包括了3个小组,组1为21名对照,组2为19名完成AIT的病人,组3为28名具有AIT治疗和治疗终止的病人。研究发现,与没有AIT治疗的对照相比

单磷酰脂质A辅助的超短疗程花粉免疫治疗(MPL)与传统的过敏原特异性免疫治疗(AIT)相比是具有吸引力的。然而,MPL-AIT的长期治疗效果还没有进行评估。最近,有研究人员在对花粉过敏的68名过敏性鼻炎患者中(年龄16.75 ±5.3岁 )进行了调查。

研究包括了3个小组,组1为21名对照,组2为19名完成AIT的病人,组3为28名具有AIT治疗和治疗终止的病人。研究发现,与没有AIT治疗的对照相比,临床症状(流鼻涕、打喷嚏、结膜炎和每周总得分)在组2和组3中显著的减少(p<0.0001)。T调控细胞和TH1/TH2细胞因子在不同病人小组之间没有差异。

最后,研究人员指出,他们试验中的对草花粉过敏的患者在MPL-AIT治疗后表现出了显著的和长期持续的症状改善,然而,仍旧需要更大群体的试验来支持上述研究发现。
