Abstract
B cells bearing the CD5 surface marker comprise a substantial minority of the circulating lymphocyte population in healthy individuals. These recently described cells have been implicated in T-independent humoral responses, immunoregulation, and autoimmunity. We undertook to enumerate circulating CD5+ B cells by three-color fluorescence activated flow cytometry in 28 patients with Crohn's disease (CD). None of the CD patients were using immunosuppressive medication. The CD patients were subdivided into "inactive" and "active" groups based upon their Crohn's disease activity index (CDAI). Thirty-two normal subjects served as a control population. The percentage of CD19+ B cells was significantly reduced in both active and inactive CD patients as compared with normal controls (P less than or equal to 0.01). CD5+ B cells were likewise found to be significantly decreased in both inactive and active CD patients (P less than or equal to 0.01) as compared with normal controls. The proportion of CD5+ B cells was significantly lower in the peripheral blood of active as compared with inactive CD patients (P less than or equal to 0.05). The finding that CD5+ B cells are reduced in CD may provide an important clue to immunological dysfunction in inflammatory bowel disease and merits further study.
