Abstract
Nonepisodic angioedema with eosinophilia (NEAE) is characterised by a single episode of angioedema localised to the extremities and peripheral eosinophilia. While NEAE can develop in response to infection or vaccination, NEAE associated with acute parvovirus B19 (B19V) infection is rare. We describe the case of a young woman with NEAE that developed during acute B19V infection. She presented with 1-week history of pruritus and polyarthralgia in the extremities, followed by the development of peripheral oedema, and was positive for anti-B19V IgM antibody. Her arthralgia improved within 2 weeks without any specific intervention; however, the oedema and pruritic erythema persisted and the peripheral eosinophil count increased. A short course of prednisolone therapy for suspected NEAE alleviated the symptoms, which have not recurred for more than 2 years. Thus, we believe that the patient was affected by NEAE and that NEAE can develop following acute B19 infection.
