Allergy:青蒿素舌下免疫疗法治疗季节过敏性鼻炎试验

2020-02-25 AlexYang MedSci原创

青蒿素是中国北方季节过敏性鼻炎(SAR)的一种重要秋季花粉过敏原。目前,还没有研究调查青蒿素过敏原免疫治疗情况。最近,有研究人员调查了青蒿素舌下免疫治疗(SLIT)的疗效和潜在机制。研究是一个随机、双盲和安慰剂对照III期临床试验,包括了71名SAR患者;并随机分配到青蒿提取物SLIT治疗组(n=47)或者安慰剂组(n=24),治疗进行的时间为32周。研究发现,在第一次花粉峰值阶段(1st PPP

青蒿素是中国北方季节过敏性鼻炎(SAR)的一种重要秋季花粉过敏原。目前,还没有研究调查青蒿素过敏原免疫治疗情况。最近,有研究人员调查了青蒿素舌下免疫治疗(SLIT)的疗效和潜在机制。

研究是一个随机、双盲和安慰剂对照III期临床试验,包括了71名SAR患者;并随机分配到青蒿提取物SLIT治疗组(n=47)或者安慰剂组(n=24),治疗进行的时间为32周。研究发现,在第一次花粉峰值阶段(1st PPP)青蒿SLIT能够显著的减少总鼻症状评分(TNSS)(从基线点的9.45±1.68到6.16±2.27),且比安慰剂治疗减少的水平显著更高(从基线点的9.29±2.09到9.05±2.40(P<0.001),并且上述改善一直持续到第二次花粉峰值阶段(2st PPP)。另外,季节前青蒿素SLIT治疗16周能够显著的减少血液中的Th2细胞和增加nTreg和Tr1细胞;并且与治疗前比较,治疗后16周和32周鼻分泌物中的半胱氨酸蛋白酶抑制剂1(CST1)水平增加。总的来说,青蒿素SLIT治疗后,17/47名患者经历了轻度局部AEs,2名患者经历了轻度全身性AEs。

最后,研究人员指出,青蒿素SLIT是青蒿素SAR患者的一种有效和安全的治疗方法。
