Two patients are described with Crohn's disease and selective IgA deficiency. Serum IgA was undetectable in each case, and immunoperoxidase studies of the lamina propria showed a gross diminution of IgA-bearing plasma cells. Peripheral blood lymphocytes, however, showed normal numbers of IgA-bearing lymphocytes. The typical clinical course and histology in these two patients suggest that IgA-mediated responses in the mucosa are not involved in the pathogenesis of Crohn's disease.
描述了两名患有克罗恩病和选择性IgA缺乏症的患者。在每个病例中血清IgA均无法检测到,固有层的免疫过氧化物酶研究显示含IgA浆细胞明显减少。然而,外周血淋巴细胞中含IgA淋巴细胞数量正常。这两名患者典型的临床病程和组织学表现提示,黏膜中IgA介导的反应不参与克罗恩病的发病机制。
