免疫賦活剤ＯＫ‐４３２により好酸球性血管性浮腫を認めた舌癌患者の１例

Abstract

Episodic angioedema associated with eosinophilia (EAE) was first reported by Gleich et al. in 1984. Clinical features of EAE include recurrent edema, urticaria, fever, increased body weight, and peripheral eosinophilia. We encountered a patient with EAE during the treatment of tongue cancer and describe the clinical features and mechanism considered responsible for the development of EAE. A 24-year-old man was given a diagnosis of tongue cancer (T 2 N 0 M 0) and underwent partial resection of the tongue. After the operation, the patient received immunochemotherapy, including UFT and OK-432, as well as radiotherapy. Shortly after beginning treatment, localized edema in the limbs and peripheral eosinophilia developed. In addition, because interleukin (IL)-5 and eosinophil cationic protein (ECP) were detected in serum, EAE was diagnosed. The symptoms disappeared after immunochemotherapy and radiotherapy were withdrawn. Because the symptoms became serious after increasing the dose of OK-432 and the patient showed positivity for OK-432 on examination of lymphocyte blastogenesis, EAE in our patient was attributed to OK-432.
