Pediatr Allergy Immunol:补充LGG可以改善特应性皮炎儿童患者治疗效果和生活质量

特应性皮炎(AD)是一种慢性炎症性皮肤病,影响多达20%的儿童人口。AD是一种多因素的慢性炎症性皮肤病,与皮肤和肠道微生物组的改变有关。特定的益生菌菌株可以调节炎症反应,对抗AD中的微生物组失调和免疫功能障碍,目前已提议使用益生菌来治疗AD。ProPAD是一项随机、双盲、对照试验,旨在研究益生菌Lacticaseibacillus rhamnosus GG(LGG)对AD患儿的治疗效果,相关结果已发表于Pediatr Allergy Immunol。

研究共纳入了100名6-36个月的AD患者,随机接受安慰剂(A组)或LGG(1 x 1010 CFU/天)(B组),为期12周。主要结果是评估LGG补充剂对AD严重程度的疗效,比较基线(T0)和12周(T12)时的特应性皮炎(SCORAD)指数。SCORAD指数降低≥8.7分被认为是最小临床重要差异(MCID)。次要结果是LGG治疗结束后4周(T16)的SCORAD指数评估,不使用救援药物的天数,婴儿皮炎生活质量问卷(IDQOL)的变化,肠道微生物组结构和功能,以及皮肤微生物组结构。

结果显示,B组患者在T12和T16达到MCID的比率明显较高(p < 0.05),并且在T16仍然维持稳定(p < 0.05),B组无需救援药物的天数较高。仅在B组患者中观察到肠道和皮肤微生物组的有益调控。

 

综上所述,该研究结果表明,补充LGG作为AD儿童患者的辅助治疗可以改善临床严重程度和生活质量,并可以减少外用类固醇的使用。这些临床改善与皮肤和肠道微生物组的积极调节以及众所周知的免疫调节性SCFA丁酸盐的增加相吻合。需要进一步研究以阐明潜在的免疫机制和对AD患者的潜在长期益处。
