Chronic active Epstein-Barr virus infection: a novel cause of lymphocytic variant hypereosinophilic syndrome.

摘要

Lymphocytic variant hypereosinophilic syndrome (LHES) is a rare disease in which cytokine production by T cells drives blood and tissue eosinophilia. We report a case of LHES in a patient with chronic active Epstein-Barr virus (CAEBV) infection and an EBV-infected T-cell clone producing eosinophilopoietic cy tokines. All methods can be found in supplemental Methods (available on the Blood Web site; see the Supplemental Materials link at the top of the online article).
