Abstract
Iron-deficiency anemia occurs most commonly in young children due to a low-iron diet and adolescent girls due to menstrual blood loss. However, children with gastrointestinal conditions such as intestinal failure, inflammatory bowel disease, celiac disease, and/or other chronic conditions, including chronic kidney disease and heart failure, also commonly have iron deficiency. Many patients with classic iron-deficiency anemia will improve with oral iron therapy. However, in children who have an incomplete response to oral iron, intravenous iron therapy is increasingly being used. Benefits of intravenous iron therapy include a rapid repletion of iron stores in addition to resolution of anemia, less gastrointestinal side effects, and relief for patients and families struggling with long-term iron supplementation. Indications for first-line therapy with intravenous iron in children with chronic conditions have also increased. Four intravenous iron formulations have approved indications in pediatrics, and many are increasingly used off-label in children as well. Here we discuss the indications and appropriate timing of intravenous iron therapy in children with a wide range of underlying etiologies.

Abstract
Iron deficiency anemia in children is a public health problem. Although oral iron treatment is the first choice, common side effects and compliance problems can cause the treatment to be interrupted. This study retrospectively evaluated children treated with intravenous (IV) iron sucrose or ferric carboxymaltose (FCM) and compared the treatment processes and efficacy. The demographic characteristics and treatment details of the 44 children with iron deficiency anemia were retrospectively evaluated. Iron sucrose was administered to 25 patients and FCM was administered to 19 patients. The IV iron infusion was applied to 64% of the patients because of unresponsiveness to oral treatment, 25% of the patients because of compliance problems, and 11% of the patients because of severe anemia. IV iron therapy increased hemoglobin, mean corpuscular volume, mean corpuscular hemoglobin, red-cell distribution width, and serum ferritin levels and decreased platelet count. The mean number of infusions per patient in the FCM group was lower, and the total treatment time was shorter. In conclusion, IV iron sucrose or FCM can be used in children with nonadherence to oral therapy and severe anemia in addition to specific indications.

Abstract
OBJECTIVE To determine whether intravenous (IV) or oral iron suppletion is superior in improving physical fitness in anemic children with inflammatory bowel disease (IBD). STUDY DESIGN We conducted a clinical trial at 11 centers. Children aged 8-18 with IBD and anemia (defined as hemoglobin [Hb] z-score < -2) were randomly assigned to a single IV dose of ferric carboxymaltose or 12 weeks of oral ferrous fumarate. Primary end point was the change in 6-minute walking distance (6MWD) from baseline, expressed as z-score. Secondary outcome was a change in Hb z-score from baseline. RESULTS We randomized 64 patients (33 IV iron and 31 oral iron) and followed them for 6 months. One month after the start of iron therapy, the 6MWD z-score of patients in the IV group had increased by 0.71 compared with -0.11 in the oral group (P = .01). At 3- and 6-month follow-ups, no significant differences in 6MWD z-scores were observed. Hb z-scores gradually increased in both groups and the rate of increase was not different between groups at 1, 3, and 6 months after initiation of iron therapy (overall P = .97). CONCLUSION In this trial involving anemic children with IBD, a single dose of IV ferric carboxymaltose was superior to oral ferrous fumarate with respect to quick improvement of physical fitness. At 3 and 6 months after initiation of therapy, no differences were discovered between oral and IV therapies. The increase of Hb over time was comparable in both treatment groups.

Eur J Pediatr 2022; 181:3781-3793. [PMID: 36056175 PMCID: PMC9439269 DOI: 10.1007/s00431-022-04582-w] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/08/2022] [Revised: 06/24/2022] [Accepted: 07/29/2022] [Indexed: 11/25/2022]
Abstract
Iron deficiency is the primary cause of anaemia worldwide and is particularly common among children and adolescents. Intravenous (IV) iron therapy is recommended for paediatric patients with certain comorbidities or if oral iron treatment has been unsuccessful. IV ferric carboxymaltose (FCM) has recently been approved by the US Food and Drug Administration for use in children aged > 1 year. This narrative review provides an overview of the available publications on the efficacy and safety of IV FCM in children and adolescents. A literature search using PubMed and Embase yielded 153 publications; 33 contained clinical data or reports on clinical experience relating to IV FCM in subjects < 18 years of age and were included in the review. No prospective, randomised controlled studies on the topic were found. Most publications were retrospective studies or case reports and included patients with various underlying conditions or patients with inflammatory bowel disease. Efficacy data were included in 27/33 publications and improvements in anaemia, and/or iron status parameters were reported in 26 of them. Safety data were included in 25/33 publications and were in line with the adverse events described in the prescribing information. CONCLUSION The available publications indicate that IV FCM, a nanomedicine with a unique and distinctive therapeutic profile, is an effective and generally well-tolerated treatment for iron deficiency or iron deficiency anaemia in children and adolescents. Despite the wealth of retrospective evidence, prospective, randomised controlled trials in the paediatric setting are still necessary. WHAT IS KNOWN • Iron deficiency and iron deficiency anaemia are usually managed using oral iron therapy, but intravenous iron therapy is recommended for certain paediatric patients. • Intravenous ferric carboxymaltose (FCM) has recently been approved in the US for use in children aged > 1 year. WHAT IS NEW • Despite evidence that FCM is effective and generally well tolerated in children and adolescents, so far, only retrospective studies, non-randomised uncontrolled prospective studies, or case reports have been published in full. • There is a strong need for prospective, randomised controlled trials on FCM in the paediatric setting.

Abstract
The intravenous iron formulations ferric carboxymaltose (FCM) and ferric derisomaltose (FDI) offer the possibility of administering a large amount of iron in one infusion. This results in faster correction of anemia and the formulations being better tolerated than oral iron formulations. This triad of logistic advantages, improved patient convenience, and fast correction of anemia explains the fact that intravenous iron formulations nowadays are frequently prescribed worldwide in the treatment of iron deficiency anemia. However, these formulations may result in hypophosphatemia by inducing a strong increase in active fibroblast growth factor-23 (FGF-23), a hormone that stimulates renal phosphate excretion. This effect is much more pronounced with FCM than with FDI, and therefore the risk of developing hypophosphatemia is remarkably higher with FCM than with FDI. Repeated use of FCM may result in severe osteomalacia, which is characterized by bone pain, Looser zones (pseudofractures), and low-trauma fractures. Intravenous iron preparations are also associated with other adverse effects, of which hypersensitivity reactions are the most important and are usually the result of a non-allergic complement activation on nanoparticles of free labile iron-Complement Activation-Related Pseudo-Allergy (CARPA). The risk on these hypersensitivity reactions can be reduced by choosing a slow infusion rate. Severe hypersensitivity reactions were reported in < 1% of prospective trials and the incidence seems comparable between the two formulations. A practical guideline has been developed based on baseline serum phosphate concentrations and predisposing risk factors, derived from published cases and risk factor analyses from trials, in order to establish the safe use of these formulations.

Abstract
BACKGROUND Parenteral iron is generally considered safe in adults, and severe adverse events are extremely rare. Ferric carboxymaltose (FCM), a third-generation parenteral iron product, is not licensed for pediatric use. OBJECTIVE The aim of this study was to present our data on the safety of FCM in children with iron deficiency (ID) and/or iron deficiency anemia (IDA) and to investigate through a systematic literature review articles reporting on the safety of FCM use in children with ID/IDA. PATIENTS AND METHODS Safety data regarding children treated with FCM for ID/IDA from four pediatric departments in Greece over a 26-month period are presented. Additionally, a literature search was performed in PubMed, Scopus, and Google Scholar on December 4, 2021 for articles reporting on the use of FCM in children with ID/IDA. Review articles, guidelines, case reports/case series, and reports on the use of FCM for conditions other than ID/IDA were excluded. Identified articles were screened for all reported adverse events (AE) that were graded according to the Common Terminology Criteria for Adverse Events, version 5.0. RESULTS In our cohort, 37 children with ID/IDA received 41 FCM infusions. All infusions were tolerated well. In addition, 11 articles reporting 1231 infusions of FCM in 866 children were identified in the literature. Among them, 52 (6%) children developed AE that were graded as mild or moderate (grades I-III). CONCLUSIONS Our patient cohort and this literature review provide further evidence for the good safety profile of FCM in children, although well-designed prospective clinical trials with appropriate safety endpoints are still required.

Abstract
Iron-deficiency anemia is the most common reason for worsening of the anemia characteristically seen in chronic kidney disease (CKD). Ferric carboxymaltose (FCM) is a macromolecular hydroxide ferric carbohydrate complex that allows high-dose iron to be administered parenterally for gradual, controlled release. The aim of this study was to retrospectively evaluate the safety and effectiveness of FCM treatment in pediatric patients with CKD non-dependent of hemodialysis, seen at a tertiary hospital. Data were collected on demographics, dosage, infusion time, laboratory results, and tolerability of the medicinal product. A total of 79 patients (40.5% girls) were included; the median age [25th percentile (P25) to 75th percentile (P75)] was 9 years (5-13). Laboratory results at 15-45 days post-infusion revealed a median increase of 1.4 g/dL (0.9-1.9) in hemoglobin, 224 μg/L (136-378.5) in ferritin, 37 μg/dL (17.5-71) in serum iron, and 18% (9.3-27.8) in transferrin saturation. All patients tolerated FCM infusions well, and no serious hypersensitivity reactions or anaphylactic reactions were observed. Only one adverse event was identified: drug extravasation at the end of the infusion in a 16-year-old patient. These data provide further evidence for the use of FCM as a safe and effective therapeutic option in pediatric patients with CKD, based on the low incidence of adverse effects, minor intervention required, and anemia improvement based on laboratory results.

Abstract
BACKGROUND Although intravenous ferric carboxymaltose (FCM) is effective in treating iron deficiency anemia (IDA) in paediatric inflammatory bowel disease (pIBD), no data are available on its post-infusion related risks. AIMS We assessed the efficacy of FCM and the rate of post-infusion hypophosphatemia in a large cohort of children with IBD and IDA. METHODS All children with IBD with IDA treated with FCM over 5-year period were reviewed. Disease activity, biohumoral assessment and treatments were evaluated at baseline, 4-6 and 12 weeks after each infusion. RESULTS 128 patients [median age at first infusion: 13 years] were identified, 81 (63.3%) were <14 years, 10 (7.8%) <6 years. Eighty-three children (64.8%) received one infusion, whilst 45 (35.2%) repeated infusions. A significant increase in Hb (p<0.001), iron (p<0.001) and ferritin (p<0.001) was observed 4-6 and 12 weeks post-infusion. Hb gain was unrelated to disease severity. Low baseline iron was the main predicting factor for repeated infusions (p<0.05). Three patients reported infusion reactions, none <6 years. Twenty-five children had low post-infusion serum phosphate (11 were <14 years, 3 <6 years). Two children developed severe hypophosphatemia. CONCLUSIONS FCM administration is effective for IDA management in pIBD, including children <6 years. Due to the high prevalence of post-infusion hypophosphatemia, serum phosphate monitoring should be mandatory.

Abstract
OBJECTIVES The aim of the study was to assess the efficacy, safety and side-effect profile of ferric carboxymaltose (FCM) for correcting IDA in children and adolescents in paediatric gastroenterology, hepatology, and nutrition. METHOD This was a retrospective study of all gastroenterology patients <18 years who had FCM (October 2015 to October 2017). Haematological and biochemical parameters were recorded pre-infusion, at 4 weeks, 3 months, 6 months, and 1 year post-infusion. Recognised side-effects were documented. RESULTS Sixty-six children received FCM during this period. Data was analysed on 61 children, 5 excluded because of inadequate data. The median age at administration was 14 years (IQR 7). Thirty-two (52%) were boys. Twenty-six (42%) were <14 years old. Seven (11.5%) were <5 years old. Seventeen (28%) were switched from oral iron supplements to FCM. The median dose of FCM delivered was 19 mg/kg. The median haemoglobin increased from 108 to 126 g/L at 1 month post-infusion (P value <0.00001). The mean cell volume also improved from 80 to 84 fL at 1 month post-infusion (P value = 0.0007). Forty-eight (94%) children corrected their anaemia after receiving FCM. Two patients (3%) reported side-effects with skin bruising and staining. CONCLUSIONS FCM appears to be effective in correcting IDA in children across a wide range of gastroenterology indications and all ages. It is effective and generally well tolerated including in very young patients. Potential side-effects can be avoided by careful monitoring during infusions.

Abstract
BACKGROUND Iron deficiency (ID) with or without anemia is a common complication of pediatric inflammatory bowel disease (IBD), causing significant morbidity. Despite this, ID remains prevalent and undertreated, related in part to questions surrounding optimal formulation and route of administration. Ferric carboxymaltose (FCM) is a recent formulation of intravenous iron, allowing higher doses and rapid infusion times. This study aims to demonstrate the efficacy and safety of FCM in paediatric patients with IBD, and explore the differences between patients with active and quiescent disease. METHODS Paediatric patients 6-18 years with IBD with iron deficiency (ID) or iron deficiency anemia (IDA) were treated prospectively with FCM at the Queensland Children's Hospital in Brisbane. Patients received FCM as a single dose of 15 mg/kg up to 1,000 mg over 15-20 min. Biochemical parameters measured prior to and approximately 8 weeks after the infusion were: hemoglobin (Hb), mean corpuscular volume (MCV), ferritin, and transferrin saturation (TS). C-reactive protein (CRP) was measured as a marker of co-existing inflammation. Resolution of anemia or ID was assessed following treatment, with adverse events captured. RESULTS A total of 101 patients received infusions of FCM during the study period and were analysed, median age 14 (IQR 14-16) years. A total of 44% of patients underwent treatment for IDA, while 56% were for ID without anemia. Following FCM infusion, 64% of patients with IDA had resolution of anemia, with 81% showing resolution for ID without anemia. Elevation of CRP throughout the study period had no influence on resolution of IDA with FCM (P=0.68), but in patients with ID, patients with quiescent disease activity were more likely to have resolution of ID [odds ratios (ORs) 5.1; P=0.03]. CONCLUSIONS Rapid, high dose FCM in children aged 6 and over is safe, well tolerated and efficacious for correction of ID. Replenishing iron in IBD is important and FCM improves our ability to meet this need.
