Possible activation of effector B cells during drug‐induced hypersensitivity syndrome

Abstract Although the development of autoimmune disorders is recognized in drug‐induced hypersensitivity syndrome (DIHS), the serial change of B‐cell activity has not been well‐addressed. Herein, the serum levels of IL‐6, IL‐10, B‐cell activating factor of the tumor necrosis factor family (BAFF), an...

Sumario:Abstract Although the development of autoimmune disorders is recognized in drug‐induced hypersensitivity syndrome (DIHS), the serial change of B‐cell activity has not been well‐addressed. Herein, the serum levels of IL‐6, IL‐10, B‐cell activating factor of the tumor necrosis factor family (BAFF), and a proliferation‐inducing ligand (APRIL) in three DIHS patients were tracked over time. While IL‐6 and IL‐10 tended to be elevated according to the disease activity, BAFF and APRIL increased during the improved phase. Our results imply that the continuous activation of B cells may be involved in the prolonged disease activity of DIHS and the development of autoimmune disorders.
