Persistent and Prolonged Parvovirus B19 Viremia in a Pediatric Patient With Acute Lymphoblastic Leukemia.

Parvovirus B19 is a small single-stranded DNA virus of the Parvoviridae family. Depending on host factors, it may produce a wide array of clinical disease states. Disease severity can range from self-limited to severe, requiring significant supportive care. Immunocompromised patients are generally affected more severely but rarely develop prolonged and persistent infections. Here, we describe a patient who was diagnosed with parvovirus during maintenance therapy for acute lymphoblastic leukemia and required therapy with intravenous immunoglobulin; the patient remained parvovirus positive according to a polymerase chain reaction testing but had no clinical symptoms for 27 months off chemotherapy.
