A Case of Transient Aplastic Crisis Induced by Human Parvovirus Bl9 in Hereditary Spherocytosis
Abstract
-
Human parvovirus B19 is a single-strand DNA virus which causes erythema infectlosum, arthralgia, aplastic crisis in patients with red cell defect, chronic anemia in immunocompromised patients, and fetal hydrops in pregnant women . A 16-year-old women was referred to our hospital with pancytopenia and splenomegaly. In peripheral blood, spherocytosis and reitculocytopenia were observed. Many giant pronormoblasts with prominent inclusion bodies and deeply blue cytoplasm were observed but late erythroblasts were not observed in bone marrow smear. Osmotic fragility of patient's red cells was significantly increased. Human parvovirus Bl9 DNA was detected by polymerase chain reaction. Only with supportive therapy, pancytopenia was spontaneously resolved.
