  印度代购提示,斑秃是一种自身免疫性疾病,导致部分或全部的头皮或身体上的毛发脱落,该病影响美国多达65万人。头皮是最常见的受累区域,但任何生长毛发的区域都可能单独或与头皮一起受累。斑秃男女发病率无差异,可在任何年龄段发生,大多数患者在40岁时开始出现症状。斑秃可伴有严重的心理后果,包括焦虑和抑郁。斑秃的发病原因不明,但在毛囊周围有淋巴细胞浸润,且有时合并其他自身免疫性疾病(如白癜风、特应性皮炎),因此也认为斑秃的发生可能存在自身免疫的发病机制。目前,还没有获得FDA批准治疗斑秃的药物。

Alopecia areata is an autoimmune disease that causes partial or total scalp or body hair loss and affects as many as 650,000 people in the United States, according to the report. The scalp is the most common area affected, but any area where hair is growing can be affected either alone or with the scalp. Alopecia areata has no difference in incidence between men and women and can occur at any age, with most patients beginning to develop symptoms at age 40. Alopecia areata can have serious psychological consequences, including anxiety and depression. The pathogenesis of alopecia areata is unknown, but there is lymphocyte infiltration around the hair follicle, and sometimes other autoimmune diseases (such as vitiligo, atopic dermatitis), so it is also believed that the occurrence of alopecia areata may have an autoimmune pathogenesis. Currently, there are no FDA-approved treatments for alopecia areata.
