简介:脱发areata是头发滤泡的疾病,与支持自体免疫的病原学的充分证据。脱发areata经常与象干癣和地衣planus那样的皮肤表明与调停免疫者的疾病被联系,或没有象自体免疫的甲状腺炎和自发的thrombocytopenic紫癜病那样的皮肤表明。Helicobacterpylori(H。pylori)感染在约50%世界人口是在场的并且包括自体免疫的甲状腺炎,自发的thrombocytopenic紫癜病,和干癣与许多调停免疫者的额外消化的混乱被联系了。有头皮和胡子的脱发areata的8瞬间历史的一个43年的老人的一个盒子被介绍。病人被一个皮肤学家正在对待并且有精神病学的支持,没有任何改进。他有消化不良的历史,脲呼吸测试证实了H。pylori感染。病人在H以后从脱发areata走进宽恕。pylori根除。如果如此的一个协会被为这个目的设计的流行病学的研究证实,新治疗学的选择能为这些病人是可得到的,特别在区域在哪儿有H的感染。pylori是高度流行的。
