Two groups of infants, one fed whole cow milk commencing at 6 months of age (n = 69) and the other continuing to receive iron-fortified infant formula (n = 98), were closely observed over their second 6 months of life. At 12 months of age, infants fed cow milk had significantly lower mean serum ferritin levels and mean corpuscular volume, higher free erythrocyte protoporphyrin values, and greater incidence of hemoglobin values less than 11 g/dl than did formula-fed infants. There were no significant differences in frequency of otitis media, wheezing episodes, nasal discharge or congestion, diaper dermatitis, constipation, guaiac-positive stools, or hospital admissions between the two groups. These data suggest that, to avoid iron deficiency, infants should continue to receive iron-fortified formula throughout the first year of life or a daily iron supplement if they are fed whole cow milk before their first birthday.

On June 30, 2009, the United States Food and Drug Administration (FDA) approved ferumoxytol (Feraheme injection, AMAG Pharmaceuticals), an iron-containing product for intravenous (IV) administration, for the treatment of iron deficiency anemia in adult patients with chronic kidney disease (CKD). The safety and efficacy of ferumoxytol were assessed in three randomized, open-label, controlled clinical trials. Two trials evaluated patients with nondialysis dependent CKD and a third trial assessed patients undergoing hemodialysis. Randomization was either to ferumoxytol or oral iron. Ferumoxytol was administered as two 510 mg IV injections, separated by 3-8 days. Oral iron, Ferro-Sequels, was administered at a dose of 100 mg twice daily for 21 days. In all three clinical trials, ferumoxytol administration increased the mean blood hemoglobin (Hgb) concentrations by approximately 1.0 g/dL over the 35 day period, a mean increase that was greater than what was observed in patients receiving oral iron. Patients receiving ferumoxytol also had increases in blood transferrin saturation (TSAT) and ferritin values. For the proposed ferumoxytol dosing regimen, 4.9% of patients had serum ferritin >or=800 ng/mL and TSAT >or=50% post-treatment. The most important ferumoxytol safety concerns were hypersensitivity reactions and/or hypotension. Anaphylaxis or anaphylactoid reactions were reported in 0.2% of subjects, and other adverse reactions potentially associated with hypersensitivity (e.g., pruritus, rash, urticaria, or wheezing) were reported in 3.7%. Hypotension was observed in 1.9%, including three patients with serious hypotensive reactions. Ferumoxytol administration may transiently affect the diagnostic ability of magnetic resonance imaging and the drug label provides further information regarding this effect.

Iron deficiency anemia (IDA) is the most common nutritional deficiency in children. Most children with IDA are treated with oral iron preparations. However, intravenous (IV) iron is an alternative for children with severe IDA who have difficulty in adhering to or absorbing oral iron. We sought to describe the safety and effectiveness of IV iron sucrose for treatment of IDA in children. Pharmacy records of children who received IV iron sucrose at a children's hospital between 2004 and 2014 were reviewed. Laboratory markers of anemia and iron studies were obtained and preinfusion and postinfusion values were compared. Records were also reviewed for adverse reactions. A total of 142 patients received IV iron sucrose over 10 years. The mean age was 11 years, 9 months. One patient of 142 developed cough and wheezing during the infusion. No other adverse events were found. IV iron sucrose resulted in a statistically significant and clinically meaningful increase in hemoglobin, mean corpuscular volume, serum iron, ferritin, and % iron saturation, with a corresponding decrease in total iron binding capacity. The use of IV iron sucrose in pediatric patients with IDA is safe and leads to a moderate increase in hemoglobin and substantial improvement in iron studies.

Idiopathic pulmonary hemosiderosis (IPH) is an uncommon chronic disorder in children. It is characterized by recurrent pulmonary hemorrhage and may result in hemoptysis and pulmonary insufficiency. The most common hematologic manifestation of IPH is iron deficiency anemia. The etiology of IPH is not known and its diagnosis may be difficult due to the variable clinical courses. The most helpful signs for identifying IPH are iron deficiency anemia and recurrent or chronic cough, hemoptysis, dyspnea, wheezing. We report here 5 pediatric cases of IPH presenting with iron deficiency anemia and without pulmonary symptoms. Mean corpuscular volume was low in all patients; iron was low in 4 out of 5 cases; total iron binding capacity was high in all of them; ferritin was low in 3 patients. At follow up, none of them had responded successfully to the iron therapy. Although they didn't present with pulmonary symptoms, chest radiographs incidentally revealed diffuse reticulonoduler shadows in all of them. Computed tomography revealed diffuse ground-glass opacities, consolidation, increased density. The diagnosis was confirmed by the detection of hemosiderin-laden macrophages in bronchoalveolar lavage fluid and gastric aspirate. If patients with iron deficiency anemia don't respond to iron therapy, they should be examined for IPH. Chest radiographs should be taken even in absence of pulmonary symptoms. Early diagnosis is important for a timely management of IPH.
