PURPOSE: Transient aplastic crisis is reported in an eight-month old child with sickle cell anemia and acute B19 parvovirus infection. This fact is uncommon in this age. PATIENT AND METHODS: The authors review the literature and describe a clinical case of an eight-month old child with sickle cell anemia presented with profound anemia and reticulocytopenia. His peripheral blood was analyzed for parvovirus B19 using the polymerase chain reaction (PCR), and for anti B19 immunoglobulin Ig M, and

RESULTS: An eight-month old child with sickle cell anemia was admitted to the hospital with fever and profound anemia (HB = 3.8g/ dl) and reticulocytopenia (2%). A diagnosis of aplastic crisis was established. The results indicate that Ig M and PCR were positive and Ig G negative. The patient needed erytrocyte transfusion, and was discharged on hospital day 4. CONCLUSIONS: The clinical and laboratory features indicate that human parvovirus B19 was the etiologic agent of an aplastic crisis in an eight-month old child. According to the international literature this event is uncommon for this age; in addition, this is the first time it appears in the Brazilian literature.
