[Transient erythroblastopenia in early childhood].
BACKGROUND
Transient erythroblastopenia is rare in young children although its frequency is increasing.


RESULTS
Six infants (four boys, two girls), aged 29-41 months (mean: 33) were admitted for polar and asthenia. Only one displayed infectious episode two months earlier. Hemoglobin ranged from 40 to 67 g/l and reticulocyte number from 1 to 10 G/l. Mean corpuscular volume was normal as was Coombs' test. There was a profound erythroblastopenia in the bone marrow in five of the six patients. Parvovirus B19 infection was excluded in all. The white cell and platelet counts were normal. All patients were given an unique blood transfusion. Reticulocytosis spontaneously appeared within a few weeks in three patients. Another patient had normal number of erythroid precursors in the bone marrow 1 month after admission.


CONCLUSIONS
Diagnosis of transient erythroblastopenia can only be made after exclusion of known causes such as drugs, virus, immune deficiency, leukemia and of Blackfan-Diamond disease. Its persistence must lead to search for another cause.
