Transient erythroblastopenia in childhood. A study of 15 cases

A survey is presented of 15 patients from the Aurora Hospital and 35 patients reported in the literature with transient erythroblastopenia of childhood (TEC). The children were hospitalized because of pallor and tiredness, some of them having signs of mild infection. They displayed normochromic anaemia, reticulocytopenia and erythroblastopenia during the severe stage of the disease. In addition, they had moderately high values for serum iron and iron-binding saturation. No other haematological, chemical or cytogenetic abnormalities could be demonstrated. 80% of the children were between 6 and 48 months old and the sexes were equally affected. In the 15 patients from the Aurora Hospital a barely significant (p=0.02-0.05) association with blood group A was recorded. Remission, indicated by a rise in the reticulocyte count, begins within a week after the diagnosis is made, even without treatment. The aetiology of the disease is unknown. Analysis of the red blood cell population at the time of diagnosis indicates that damage to the red cell precursors has occurred 2-3 months before the child is brought for examination.
