Development of ulcerative colitis during the course of rheumatoid arthritis: Association with selective IgA deficiency

有风湿性关节炎(RA ) 的 29 年的历史的一个 56 岁的女人进入医院，抱怨高发烧，腹的疼痛和严重流血腹泻。结肠镜检查与从直肠延长到远侧的横向的冒号的自发的流血、弥漫的侵蚀和溃疡揭示了脆、水肿的粘膜。直肠的活体检视的组织病理学说的调查结果与 ulcerative (UC ) 兼容。作为有严重活跃左边的 UC 被诊断，她成功地被对待，静脉内的甲基氢化尼松由氢化尼松和 leukocytapheresis 列在后面。实验室测试揭示了低浆液和口水 IgA 层次，它可能在 UC 的发展起一个作用。到我们的知识，这是发生在 RA 的功课期间的 UC 的第一个盒子，由选择 IgA 缺乏伴随了。

A 56-year-old woman with a 29-year history of rheumatoid arthritis （RA） was admitted to the hospital, complaining of high fever, abdominal pain and severe bloody diarrhea. Colonoscopy revealed friable and edematous mucosa with spontaneous bleeding, diffuse erosions and ulcers extending from the rectum to the distal transverse colon. Histopathological findings of rectal biopsies were compatible with ulcerative colitis （UC）. Being diagnosed as having severe active leftside UC, she was successfully treated with intravenous methylprednisolone followed by prednisolone and leukocytapheresis. Laboratory tests revealed low serum and saliva IgA levels, which might play a role in the development of UC. To our knowledge, this is the first case of UC occurring during the course of RA, accompanied by selective IgA deficiency.
