Classic Transient Erythroblastopenia of Childhood With Human Parvovirus B19 Genome Detection in the Blood and Bone Marrow

Abstract: The etiology of transient erythroblastopenia of childhood (TEC) remains unknown, although an association with viral infections has been proposed. The authors describe a 3.5-year-old girl with classic TEC concomitantly with human parvovirus B19 (HPV) infection. The infection was evident by detection of HPV genome in the blood and the bone marrow by polymerase chain reaction. Viral genome was no longer detected when the TEC resolved clinically. The patient was immunocompetent and the anemia has not recurred. To … Show more

“…In patient 5, although the lymphoproliferative disorder was considered as controlled at the onset of acute anemia, the role of EBV as a trigger of autoimmunity can be discussed. Other viruses may be responsible for hematological disorders, such as anemia with parvovirus B19 (11). However this is mostly a central defect in erythrogenesis, and not a peripheral destruction of red cells.…”

“…Es por esto que se piensa que el desorden sería gatillado por un factor ambiental en sujetos genéticamente predispuestos 4,7 . En diferentes series reportadas, los resultados son poco concordantes, en nuestra experiencia no encontramos relación con infección viral, mientras otros autores sí la reportan 8,9 . Se ha propuesto que el cuadro podría ser causado por infecciones virales ya que se ha descrito la ocurrencia de cuadro viral previo (respiratorio alto o gastrointestinal) hasta en la mitad de los casos, con un promedio de un mes atrás, lo que es apoyado además por la distribución etaria del cuadro, la ausencia de recaída y la actividad del sistema inmune; sin embargo, esto no ha sido probado 2,4 .…”

“…Hallazgos de laboratorio en pacientes con eritroblastopenia transitoria de la infancia especificidad de IgM alcanza un 90% mientras que la sensibilidad es sólo de 50%, lo que convierte a la PCR en médula ósea en el examen de elección para descartar compromiso por este virus. En dos de nuestros casos la PCR en médula ósea fue negativa para parvovirus 9,10 . La necesidad de estudio viral no es absoluta.…”
