Background And AimsIncreasing evidence in adults demonstrates efficacy and safety of IV iron in inflammatory Bowel disease (IBD) associated iron deficiency anemia; however, evidence in pediatric patients is yet scarce and no previous study has included a long follow-up. This study aimed to evaluate safety and efficacy of IV iron (primary end point), and the need of re-treatment (secondary end point), in this setting.MethodsProspective recruitment (40 months); PCDAI determined before and after treatment; anemia defined according to WHO criteria; IV iron treatment included iron sucrose and ferric carboxymaltose. Primary and secondary endpoints included hemoglobin, serum ferritin, transferrin saturation at baseline and 4-6 weeks after treatment; and the need of re-treatment during the median follow-up period (18 months), respectively.ResultsNineteen patients (median age: 15.5 years) with remissive/mild disease were included. At recruitment, the median hemoglobin was 10.5 g/dl, (median s-ferritin: 20.1 ug/l, median transferrin saturation; 6%) and 4-6 weeks after treatment was 12.7 g/dl. Median hemoglobin according to age groups before vs. after treatment: <12 years:11 vs. 12.0 g/dl; females ≥12 years:9.9 vs. 12.6 g/dl; and males ≥12 years:11.1 vs. 13.3 g/dl. Patients with remissive vs. mild disease had median Hb of 10.5 g/dl vs. 10.6 g/dl, and median s-ferritin: 6.8 ug/dl vs. 43.3 ug/dl, respectively). Nine patients were treated with iron sucrose (median dose 672.6 mg/dl) and 10 patients with ferric carboxymaltose (median dose 811.5 mg/dl). No major adverse reactions occurred. Six patients needed re-treatment after a median 15.5 months period.ConclusionsOur prospective study, concerning pediatric IBD anemia patients with remission/mild disease and a significant follow-up, emphasizes efficacy and safety of IV-iron and the importance of long-term follow-up of iron status.SummaryIn pediatric IBD iron anemia, the evidence supporting the efficacy and safety of IV-iron is scare. This prospective study aims to evaluate the safety and efficacy (short and long term) of IV-iron in these patients. Nineteen pediatric CD patients were evaluated before and after IV iron treatment (40-month period).The median Hb before and after IV iron was 10.5 and 12.7 g/dl, respectively. No major adverse reactions were documented. Six patients needed re-treatment (median period of 15.5 months). This study further demonstrates the efficacy and safety of IV iron. It reinforces the importance of long-term follow-up of the iron status in pediatric CD patients.
