Differentiation of transient erythroblastopenia of childhood from congenital hypoplastic anemia

The Journal of Pediatrics
W C Wang, William C Mentzer


Erythrocyte properties of patients with congenital hypoplastic anemia were compared to those of patients with transient erythroblastopenia of childhood. The MCV was less than 85 in all nine TEC patients studied and greater than 90 in all 11 CHA patients. Hemoglobin F concentration was elevated beyond the normal level for age in eight CHA patients and almost always normal in TEC. The i antigen score was more likely to be elevated in CHA than in TEC. The activities of transaminase, aldolase, phosphofructokinase, and glutathione peroxidase were higher in CHA than in TEC (p less than 0.001). Some abnormal properties (namely, MCV and hemoglobi n F concentration) of CHA erythrocytes, present during remission but accentuated during relapse, seemed to vary with changes in serum erythropoietin. Early differentiation of TEC and CHA appears feasible, allowing prompt provision of a favorable prognosis and the avoidance of unnecessary corticosteroid therapy in TEC.

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
