Transient erythroblastopenia of childhood
|Transient erythroblastopenia of childhood|
Signs and symptoms
Individuals with TEC have a median age of presentation of 18–26 months; however, the disorder may occur in infants younger than 6 months and in children as old as age 10 years. Because of the gradual onset of the anemia, children are often healthier than expected from their low hemoglobin levels.
The cause of TEC is unknown, but it thought to be triggered by a viral infection. While rare cases have been attributed to infection with Parvovirus B19, the majority of cases are not related to Parvovirus infection. This is in contrast to transient aplastic crisis, seen in patients with hemoglobinopathies such as sickle cell disease, which is usually caused by Parvovirus infection.
Most patients recover completely within 1–2 months. However many reported cases have lasted 18–24 months and longer.
