Enlarged spleen, fever, increased susceptibility to infections, and thrombocytosis, are manifestations of iron deficiency which are relatively specific of pediatric patients. Iron deficiency anemia is part of everyday pediatrics. Patients are referred to the hematologist in the following situations: 1) Therapy is ineffective for one of the following reasons: the hypochromic anemia is not caused by iron deficiency (hemoglobinopathies); iron is less efficiently used because of transferrin deficiency or infectious, inflammatory or cancerous disease; iron therapy is inadequate either because of insufficient dosage or of suboptimal duration. 2) A relapse occurs in spite of adequate therapy. Before investigating the digestive tract, abnormal hemostasis. Osler-Weber-Rendu syndrome and pulmonary hemosiderosis should be considered. 3) Iron deficiency anemia is less common in adolescents. This condition, known as chlorosis, results mainly from increased needs, unbalanced diet, and onset of menses. In some cases no explanation is found but iron therapy leads to recovery. 4) Difficult problems arise in patients with complex anemias: iron deficiency with folic acid or vitamin B12 deficiency; hyposideremia complicating one of the hemoglobinopathies.
