The relationship of iron-binding proteins to prognosis was studied in 50 children at the Children's Hospital of Philadelphia, newly diagnosed with Hodgkin's disease (HD). There were five patients with Stage I, 18 with Stage II, 14 with Stage III, and 13 with Stage IV. Initial serum ferritin, transferrin, iron, hemoglobin (Hb), erythrocyte sedimentation rate (ESR), and A or B symptoms were analyzed for their association with progression-free survival (PFS). There was a linear increase of mean and median ferritin levels and a decrease of mean and median transferrin levels with advancing stages. Also, there was a significant inverse correlation between ferritin and transferrin (P less than 0.001). In univariate analyses, high ferritin (greater than 142 ng/ml) (P = 0.02) and low transferrin (less than or equal to 250 mg/dl) (P = 0.008) were significantly associated with poor PFS. Serum iron, Hb, ESR, and A or B symptoms were not associated with PFS. Stepwise proportional hazards regression analysis of all factors showed that transferrin was the only factor significantly associated with PFS. These preliminary results suggest that serum transferrin can also be used as a prognostic factor in addition to serum ferritin and that it may be helpful to assay both serum ferritin and transferrin as prognostic factors in childhood HD. Further testing of large groups of patients is needed to determine whether they are independent of tumor bulk and other established prognostic factors.

Pediatric patients with end-stage renal disease undergoing hemodialysis (HD) frequently develop anemia. Administration of recombinant human erythropoietin (rHuEPO) is effective in managing this anemia, although the additional demand for iron often results in iron deficiency. In adult patients undergoing HD, intravenous (IV) iron administration is known to replenish iron stores more effectively than oral iron administration. Nevertheless, IV iron supplementation is underutilized in pediatric patients, possibly because of unproved safety in this population. This international, multicenter study investigated the safety and efficacy of two dosing regimens (1.5 mg kg(-1) and 3.0 mg kg(-1)) of sodium ferric gluconate complex (SFGC) therapy, during eight consecutive HD sessions, in iron-deficient pediatric HD patients receiving concomitant rHuEPO therapy. Safety was evaluated in 66 patients and efficacy was evaluated in 56 patients. Significant increases from baseline were observed in both treatment groups 2 and 4 weeks after cessation of SFGC dosing for mean hemoglobin, hematocrit, transferrin saturation, serum ferritin, and reticulocyte hemoglobin content. Efficacy and safety profiles were comparable for 1.5 mg kg(-1) and 3.0 mg kg(-1) SFGC with no unexpected adverse events with either dose. Administration of SFGC was safe and efficacious in the pediatric HD population. Given the equivalent efficacy of the two doses, an initial dosing regimen of 1.5 mg kg(-1) is recommended for pediatric HD patients.

Intravenous iron therapy is recommended for children and adults who receive hemodialysis (HD) and recombinant human erythropoietin (rHuEPO). However, limited information exists on the use of any maintenance IV iron regimen in children. Therefore, we conducted a prospective, multicenter, open-label trial of maintenance therapy with sodium ferric gluconate complex (SFGC) in iron-replete pediatric HD patients receiving rHuEPO. Patients received SFGC weekly at an initial dose of 1.0 mg kg(-1) week(-1), not to exceed 125 mg. Doses could be adjusted based on iron indices. Twenty-three patients (mean age: 13.2+/-2.39 years) were enrolled and received at least one dose of SFGC, while twelve patients completed the study. After 12 weeks of treatment, the mean SFGC dose delivered was 1.0 mg/kg. Mean TSAT and serum ferritin levels remained within NKF-K/DOQI target ranges and the mean Hgb level remained unchanged from baseline. No unexpected or unusual safety risks were associated with SFGC use. In summary, this experience provides evidence for the safety and efficacy of intravenous SFGC and supports the recommendation that the maintenance SFGC starting dose should be 1.0 mg/kg, not to exceed 125 mg, with subsequent adjustments made according to TSAT and/or serum ferritin levels.
