Pediatric Crohn's disease, iron deficiency anemia and intravenous iron treatment: a follow-up study

AbstractBackground and aims: Increasing 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.Methods: Prospective 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.Results: Nineteen patients (median age: 15.5 years) with remissive/mild disease were included. At recruitment, the median hemoglobin was 10.5 g/dl, (median s-ferriti...
