Abstract

SUMMARY: Although the standard of care in febrile neutropenic patients includes the initiation of empirical antibacterial and antifungal therapy, many patients do not respond and need further diagnostic work up and treatment. Here, we report on an immunosuppressed neutropenic patient with a prolonged episode of fever unresponsive to empirical antibacterial therapy. Herpes polymerase chain reaction revealed systemic reactivation of herpes simplex virus type 1 (HSV-1) infection and treatment with acyclovir was associated with the prompt resolution of signs and symptoms of infection. Screening for HSV in persistently febrile neutropenic patients may discover HSV reactivation that can be treated successfully by acyclovir administration.
