一项新的研究表明:培养人皮肤上的有益菌使得个体化的皮肤病(如:湿疹)治疗策略成为可能。

最新证据表明,体内微生物群落中的有益菌可用于治疗有害菌导致的传染病。由于目前某些有害细菌对于抗生素耐药性日益增长,这可能是抗菌药物研究的新方向。

每个人的皮肤上都附着着大量的有益和有害菌,二者的比例也大不相同。过敏性皮肤炎是最常见的一种湿疹,症状表现为发炎疼痛,将近一千八百万的美国人都深受其害。有益有害菌比例的失衡可能是部分人群患过敏性皮肤炎的原因。

来自UCSD的皮肤病医生Richard Gallo 在美联社采访中说道:"患有这种湿疹的患者,在皮肤上有大量的细菌,但并不是有害菌,但目前原因尚不完全清楚。"

为了弄清这些细菌群体的组成,Gallo和他的团队检测了30位健康人及49位湿疹患者的皮肤培养物化验标本。

检测了上千个菌落后,他们发现健康人的皮肤上富含两种菌--溶血性葡萄球菌和表皮葡萄球菌。这两种菌都能够抵抗金黄色葡萄球菌。金黄色葡萄球菌是一种有害菌,是超级抗药细菌MRSA的前体。

研究团队给予患者胳膊洗液处理,使他们的皮肤上附着与健康人相同数量的有益菌(约每平方厘米含10万个菌落单位)。其中两位患者仅仅在24小时后,皮肤上的金黄色葡萄球菌就消失了,而另外三位病人皮肤上的金黄色葡萄球菌数量显著下降。

除了金黄色葡萄球菌的数量减少外,研究团队并没有宣布湿疹的症状是否得到缓解,但他们认为,他们已经掌握了这种治疗的基本原理。

另一个好消息是,与广谱抗生素相比,这种治疗方式可以通过特定菌种的培养,做到只针对有害细菌,不同于抗生素"好坏皆杀"。

研究发表在《Science Translational Medicine》杂志上。

快速上手:儿童湿疹诊疗五大要点

湿疹是一种剧烈瘙痒的皮肤炎症,很多孩子都发生过不止一次的湿疹,由于瘙痒引起的搔抓会导致皮肤损伤和感染,常引起患儿的不适和家长的恐慌。特应性皮炎是湿疹的常见原因,主要引起皮肤的红斑、瘙痒、发热、疼痛、甚至是小水泡。研究认为湿疹有遗传倾向,大约一半的湿疹儿童可能存在干草热或哮喘,湿疹患儿的家庭成员常有干草热、哮喘或其他过敏性疾病。湿疹本身并不是过敏,但是过敏反应能诱导湿疹发生,一些环境因素能诱发湿疹。
