Chronic-Relapsing cutaneous leukocytoclastic vasculitis in a young patient with reduced EBV-specific T cell response using enzyme-linked immunospot (ELISPOT) assay successfully treated with Valaciclovir

Among different pathogens, opportunistic viral infection caused by EBV is particularly relevant. This gammaherpesvirus, belonging to the Herpesviridae family, may complicate the disease course in different clinical settings by inducing pathological EBV pictures in patients with a defective immunologic response. Our report evaluated EBV-specific T cell responses by IFN- γ ELISPOT assay, which revealed defective EBV specific immunological response.
