Abstract:

目的探讨特异益生菌干预是否可以减少常年性变应性鼻炎(perennialallergicrhinitis,PAR)发作次数,减轻PAR症状;益生菌抑制PAR发病是否与肠道或全身免疫有关。方法2013年春季和2014年春季(2-4月),我院收治PAR患者50例进入研究序列,每例患者允许获得独立编码的胶囊药物,每天确保口服胶囊1粒,连续3个月。益生菌组药物为益生菌胶囊,每粒含5×109CFU(25%嗜酸乳杆菌和75%乳双歧杆菌)。对照组为纤维素胶囊。2组PAR患者均口服氯雷他定10mg/d,治疗1个月。分别于治疗后1、3个月进行随访,完成以下指标检测:症状VAS评分、鼻腔分泌物及全血嗜酸性粒细胞测定,血清sIgE、细胞因子IL-4及IFN-γ浓度测定,粪便IgA浓度测定。结果2组治疗前检测的上述指标差异无统计学意义(P>0.05)。2组症状VAS评分在治疗后1个月均降低;治疗后3个月益生菌组评分低于对照组(P<0.05)。治疗后1、3个月,益生菌组鼻腔分泌物嗜酸性粒细胞检出率较对照组明显降低(P<0.05,P<0.01)。治疗后1、3个月,2组血清sIgE出现先上升后下降的现象,组间差异均有统计学意义(P<0.05)。治疗后1个月,2组IL-4均上升,组间差异有统计学意义(P<0.05);治疗后3个月IL-4升高被益生菌干预阻断,而对照组IL-4继续升高,组间差异有统计学意义(P<0.01)。2组全血嗜酸性粒细胞计数和血清IFN-γ水平在治疗后1、3个月无明显变化(P>0.05)。治疗后1、3个月,益生菌组粪便中IgA持续降低,而对照组IgA水平持续升高,组间差异有统计学意义(P<0.01)。结论口服特异益生菌组合能够减少PAR的发病,减轻鼻腔黏膜的变应性炎症。益生菌可能通过调节肠道或全身免疫状态,抑制PAR的发病。
