OBJECTIVE: To assess the effects of iron supplementation on immunological parameters of adolescents with varying iron status. METHOD:Adolescents of both sexes with varying iron status were allocated to four treatment groups by using inclusion criteria. Three of the four groups received iron(III)-hydroxide polymaltose complex (IPC, Maltofer) containing 100 mg of iron 6 days a week for 8 months. The fourth group was given a placebo. Immunological parameters were assessed at baseline and after 4 and 8 months of supplementation. RESULTS: Increases from baseline to 4 months and from 4 to 8 months of supplementation were observed for Bactericidal Capacity of Neutrophils (BCA), NitroBlue Tetrazolium Reduction Test (NBT), and phytohaemagglutinin (PHA) in all three supplemented groups. No increase was found in the control placebo group except for PHA. No side effects were noted in any participants. CONCLUSION:IPC supplementation for eight months led to significant improvements of immunological parameters in iron deficient adolescents with and without anemia.
