Abstract
Intravenous iron has become an essential component for the treatment of iron deficiency and iron deficiency anemia. Individuals administering Intravenous iron should have knowledge in intravenous iron administration, including a pre-infusion assessment to evaluate infusion reaction risks, pre- and post-infusion monitoring, identification of and management of infusion reactions, accurate documentation of these reactions, laboratory monitoring and recognition and management of treatment-emergent hypophosphatemia. This comprehensive consensus provides step-by-step guidance and tools for practitioners to promote safe delivery of intravenous iron, recognition, and management of infusion reactions and treatment-emergent hypophosphatemia.

Abstract
Kidney replacement therapies (KRTs) including hemodialysis (HD) are one of the treatment options for most of the patients with end-stage kidney disease. Although HD is vital for these patients, it is not hundred percent physiological, and various adverse events including hypersensitivity reactions may occur. Fortunately, these reactions are rare in total and less when compared to previous decades, but it is still very important for at least two reasons: First, the number of patients receiving kidney replacement treatment is increasing globally; and the cumulative number of these reactions may be substantial. Second, although most of these reactions are mild, some of them may be very severe and even lead to mortality. Thus, it is very important to have basic knowledge and skills to diagnose and treat these reactions. Hypersensitivity reactions can occur at any component of dialysis machinery (access, extracorporeal circuit, medications, etc.). The most important preventive measure is to avoid the allergen. However, even with very specific test, sometimes the allergen cannot be found. In mild conditions, HD can be contained with non-specific treatment (topical creams, antihistaminics, corticosteroids). In more severe conditions, treatment must be stopped immediately, blood should not be returned to patient, drugs must be stopped, and rules of general emergency treatment must be followed.

Abstract
INTRODUCTION Postoperative anaemia is prevalent in adult spinal deformity (ASD) surgery in association with unfavourable outcomes. Ferric derisomaltose, a novel iron supplement, offers a promising solution in rapidly treating postoperative anaemia. However, the clinical evidence of its effect on patients receiving spinal surgery remains inadequate. This randomised controlled trial aims to evaluate the safety and efficacy of ferric derisomaltose on postoperative anaemia in ASD patients. METHODS AND ANALYSIS This single-centre, phase 4, randomised controlled trial will be conducted at Department of Orthopaedics at Peking Union Medical College Hospital and aims to recruit adult patients who received ASD surgery with postoperative anaemia. Eligible participants will be randomly assigned to receive ferric derisomaltose infusion or oral ferrous succinate. The primary outcome is the change in haemoglobin concentrations from postoperative days 1-14. Secondary outcomes include changes in iron parameters, reticulocyte parameters, postoperative complications, allogeneic red blood cell infusion rates, length of hospital stay, functional assessment and quality-of-life evaluation. ETHICS AND DISSEMINATION This study has been approved by the Research Ethics Committee of Peking Union Medical College Hospital and registered at ClinicalTrials.gov. Informed consent will be obtained from all participants prior to enrolment and the study will be conducted in accordance with the principles of the Declaration of Helsinki. The results of this study are expected to be disseminated through peer-reviewed journals and academic conferences. TRIAL REGISTRATION NUMBER NCT05714007.

Abstract
Intravenous iron has become a major component of the therapeutic armamentarium for iron deficiency and iron deficiency anemia. The earliest formulations were associated with unacceptable toxicity. Newer formulations, with complex carbohydrate cores that bind elemental iron more tightly, allow the administration of full therapeutic doses in 15 to 60 minutes. Nonetheless, a folklore of danger, fueled by earlier formulations no longer available, continues to foment caution. Complement-mediated minor infusion reactions, referred to as complement activation-related pseudo-allergy, resolve without therapy. Inappropriate intervention with vasopressors and H1 blockers converts these minor reactions into hemodynamically significant adverse events. Four new formulations, low-molecular-weight iron dextran, ferumoxytol, ferric carboxymaltose, and ferric derisomaltose, all approved for the treatment of iron deficiency in a host of conditions, are now widely used with an excellent safety profile. Herein, the administration, safety, indications, and management of infusion reactions are discussed. Treatment-emergent hypophosphatemia, a newly recognized side effect for some formulations, is also reviewed. Based on the preponderance of published evidence, intravenous iron should be moved up-front for the treatment of iron deficiency and iron deficiency anemia in those conditions in which oral iron is suboptimal.

Abstract
Intravenous iron is commonly used to treat iron deficiency anemia in non-dialysis chronic kidney disease (ND-CKD). There is a paucity of information on the potential impact of intravenous iron on patient reported outcome measures, functional status and markers of cardiovascular health. As part of the secondary analysis of this double-blind exploratory randomized controlled trial focusing on patients with iron deficiency (+ /- anemia) and ND-CKD (serum ferritin < 200 µg/L or transferrin saturation ≤ 20% and serum ferritin 200-299 µg/L; CKD stages: 3a-5), 26 patients were randomized in a 1:1 ratio to receive ferric derisomaltose or ferric carboxymaltose. Participants received 1000 mg at baseline and 500-1000 mg at one month to achieve iron repletion. Quality of life and fatigue status were assessed using the Short-Form (36) questionnaire and the fatigue severity scale. Functional status was evaluated using the Duke Activity Status Index and the 1-min-sit-to-stand test. Cardiac markers such as NT-proBNP, Troponin T and pulse wave velocity were monitored. Intravenous iron was associated with similar improvements in most domains of the Short-Form (36) questionnaire, fatigue status, and 1-min-sit-to-stand ability increased significantly by the end of the trial in both groups (p < 0.001). Markers of cardiac function remained stable, with no arterial stiffness impact. Longer term studies are required to further evaluate the impact of intravenous iron on quality of life and cardiac safety in patients with ND-CKD.

Abstract
Anemia is a common complication of chronic kidney disease (CKD) and is associated with a decrease in quality of life and an increased risk of transfusions, morbidity and mortality, and progression of CKD. The Anemia Working Group of the Sociedad Española de Nefrología conducted a Delphi study among experts in anemia in CKD to agree on relevant unanswered questions by existing evidence. The RAND/UCLA consensus methodology was used. We defined 15 questions with a PICO structure, followed by a review in scientific literature databases. Statements to each question were developed based on that literature review. Nineteen experts evaluated them using an iterative Two-Round Delphi-like process. Sixteen statements were agreed in response to 8 questions related to iron deficiency and supplementation with Fe (impact and management of iron deficiency with or without anemia, iron deficiency markers, safety of i.v. iron) and 7 related to erythropoiesis stimulating agents (ESAs) and/or hypoxia-inducible factor stabilizers (HIF), reaching consensus on all of them (individualization of the Hb objective, impact and management of resistance to ESA, ESA in the immediate post-transplant period and HIF stabilizers: impact on ferrokinetics, interaction with inflammation and cardiovascular safety). There is a need for clinical studies addressing the effects of correction of iron deficiency independently of anemia and the impact of anemia treatment with various ESA on quality of life, progression of CKD and cardiovascular events.

Abstract
Hypophosphatemia is a recognized side effect of treatment of iron deficiency anemias with injectable iron. We analyzed 35 clinical trials that used ferric carboxymaltose (FCM) or iron sucrose (IS). Hypophosphatemia prevalence ranged from 0 to 91.7%. FCM-induced a significant (P<0.001) greater hypophosphatemia prevalence and phosphatemia decrease than IS (52.0% [95% CI: 42.2-61.8%] vs. 7.7% [95% CI: -2.8 to 18.2%] and -1.12mmol/L [95% CI: -1.36 to -0.89mmol/L] vs. -0.13mmol/L [95% CI: -0.59 to 0.32mmol/L]). FCM-induced hypophosphatemia was dose-dependent. The nadir of hypophosphatemia was reached in almost all studies after 7 and 14days. Hypophosphatemia persisted at the end of the study in 53.8% of the reported studies that used FCM and lasted up to 6months. FCM-induced an increase in intact circulating fibroblast growth factor 23 and in renal phosphorus excretion while serum 1-25 dihydroxyvitamin D was decreased. Risk factors for hypophosphatemia after FCM therapy were low basal circulating phosphate or ferritin, low body weight, high glomerular filtration rate, serum parathyroid hormone or hemoglobin and age, whereas renal insufficiency was associated with a lower risk. In conclusion, hypophosphatemia is common after treatment with injectable iron, FCM being associated with a higher risk than IS and with disorders of phosphocalcium metabolism. Monitoring of blood phosphate and 1-25 dihydroxyvitamin D could be considered during FCM therapy.

Abstract
BACKGROUND Impaired quality of life is common in patients with end-stage kidney disease. We report the baseline quality of life measures in participants from the PIVOTAL randomized controlled trial and the potential relationship with the primary outcome (all-cause mortality, myocardial infarction, stroke, and heart failure hospitalisation), and associations with key baseline characteristics. METHODS This was a post hoc analysis of 2141 patients enrolled in the PIVOTAL trial. Quality of life was measured using EQ5D index, Visual Analogue Scale, and the KD-QoL [Physical Component Score and Mental Component Score]. RESULTS Mean baseline EQ5D index and visual analogue scale scores were 0.68 and 60.7 and 33.7 (Physical Component Score) and 46.0 (Mental Component Score), respectively. Female sex, higher Body Mass Index, diabetes mellitus, history of myocardial infarction, stroke or heart failure were associated with significantly worse EQ5D index and visual analogue scale. Higher C-reactive protein levels and lower transferrin saturation were associated with worse quality of life. Haemoglobin was not an independent predictor of quality of life. A lower transferrin saturation was an independent predictor of worse physical component score. A higher C-reactive protein level was associated with most aspects of worse quality of life. Impaired functional status was associated with mortality. CONCLUSION Quality of life was impaired in patients starting haemodialysis. A higher C-reactive protein level level was a consistent independent predictor of the majority of worse quality of life. Transferrin saturation ≤ 20% was associated with worse physical component score of quality of life. Baseline quality of life was predictive of all-cause mortality and the primary outcome measure.

Abstract
Modern intravenous iron compounds (e.g., ferric carboxymaltose [FCM] and ferric derisomaltose [FDI]) are utilized in the treatment of iron deficiency anemia in non-dialysis-dependent chronic kidney disease (ND-CKD). Product-specific alterations in the metabolism of fibroblast growth factor 23 (FGF-23) leading to hypophosphatemia have been described for certain intravenous iron compounds, such as FCM, with potential effects on bone and cardiovascular health and quality of life. No prior head-to-head comparison between FCM and FDI exists in ND-CKD. This single-center exploratory double-blind randomized controlled trial primarily aimed to investigate the differential impact of FCM and FDI on FGF-23 and phosphate in patients with iron deficiency +/- anemia and ND-CKD (stages 3a-5 - serum ferritin <200 μg/L or serum ferritin 200-299 μg/L and transferrin saturation <20%). Patients were randomized (1:1) to receive either FCM or FDI over two infusions (1 month apart). Follow-up was 3 months. Measurements of serum intact FGF-23, phosphate, vitamin D metabolites, parathyroid hormone, other bone metabolism, cardiovascular, and quality of life markers were monitored. 168 patients were prescreened. Thirty-five patients were screened; 26 patients were randomized. The mean (standard deviation) age was 67.9 (12.4) years and 17 participants were male. Most participants had stage 4 CKD (median [interquartile range] estimated glomerular filtration rate [eGFR]: 18.0 [11.3] mL/min/1.73 m2). A higher than normal median (interquartile range) level of intact FGF-23 (212.1 [116.4] pg/mL) was noted. Serum phosphate was within normal range, while parathyroid hormone was higher and 1,25 (OH)2 vitamin D lower than the normal range. The "Iron and Phosphaturia - ExplorIRON-CKD" trial will provide important information regarding the differential effect of intravenous iron products in terms of FGF-23, phosphate, and other markers of bone and cardiovascular metabolism, alongside patient-reported outcome measures in patients with ND-CKD.

Abstract
Objective: To evaluate the efficacy and safety of intravenous iron supplementation in patients with recurrent iron deficiency anemia (IDA) . Methods: This retrospective analysis of 90 patients with recurrent IDA from May 2012 to December 2021 was conducted, comparing the efficacy and safety of the intravenous iron therapy group and the oral iron therapy group. Results: Among the 90 patients with recurrent IDA, 20 were males and 70 were females, with a median age of 40 (range: 14-85) years. A total of 60 patients received intravenous iron supplementation and 30 received oral iron supplementation. The hematologic response rates in the intravenous iron group were significantly higher than those in the oral iron group at 4 and 8 weeks after treatment [80.0% (48/60) vs 3.3% (1/30) and 96.7% (58/60) vs 46.7% (14/30), all P<0.001, respectively]. The median increase in hemoglobin levels was also significantly higher in the intravenous iron group than in the oral iron group [38 (4, 66) g/L vs 7 (1, 22) g/L at week 4 and 44.5 (18, 80) g/L vs 19 (3, 53) g/L at week 8, all P<0.001]. The intravenous iron group had a significantly higher proportion of patients who achieved normal hemoglobin levels than the oral iron group (55.0% vs 0 and 90% vs 43.3%, all P<0.001, respectively). Iron metabolism indicators were tested before and after 8 weeks of treatment in 26 and 7 patients in the intravenous and oral iron groups, respectively. The median increase in serum ferritin (SF) levels in the intravenous iron group 8 weeks after treatment was 113.7 (49.7, 413.5) μg/L, and 54% (14/26) of these patients had SF levels of ≥100 μg/L, which was significantly higher than the median increase in SF levels in the oral iron group [14.0 (5.8, 84.2) μg/L, t=4.760, P<0.001] and the proportion of patients with SF levels of ≥100 μg/L (P=0.013). The incidence of adverse reactions was 3.3% (2/60) in the intravenous iron group, which was significantly lower than that in the oral iron group [20.0% (6/30), P=0.015]. Conclusion: Intravenous iron supplementation is more effective for hematologic response, faster hemoglobin increase, and higher iron storage replenishment rates compared with oral iron supplementation in patients with recurrent IDA, and it is well tolerated by patients.

Abstract
BACKGROUND Intravenous iron is the preferred treatment for patients with iron deficiency anemia in a variety of clinical situations. Although uncommon, administration of modern IV iron formulations can result in hypersensitivity reactions (HSRs) and, rarely, anaphylactic or anaphylactoid reactions. AIM The objective of the present study was to systematically review the literature to identify and analyze data on the incidence of HSRs after administration of ferric derisomaltose (FDI) or ferric carboxymaltose (FCM). METHOD A prospectively-registered systematic literature review was conducted to identify prospective randomized controlled trials comparing FDI and FCM with other intravenous iron formulations or oral iron. Searches were conducted in PubMed (including MEDLINE), EMBASE, and the Cochrane Library in November 2020. The relative incidence of serious or severe HSRs occurring on the day or day after dosing of intravenous iron, recorded under the standardized Medical Dictionary for Regulatory Activities query for anaphylactic reaction. RESULTS Data were obtained from seven randomized controlled trials of FCM (N = 2683) and ten of FDI (N = 3474) enrolling 10,467 patients in total. The number of patients experiencing any serious or severe HSR event was 29/2683 (1.08%) with FCM versus 5/3474 with FDI (0.14%). Bayesian inference of proportions showed the event rates to be significantly lower with FDI relative to FCM. CONCLUSION HSR events were uncommon with both intravenous iron formulations; however, the present study showed a significantly lower incidence of HSRs with FDI relative to FCM. Further large-scale, head-to-head trials of the iron formulations would be required to confirm this finding.

Abstract
Background Iron deficiency anemia is common in patients with advanced chronic kidney disease (CKD). Ferric derisomaltose (FDI) enables iron repletion in a single dose, unlike other forms of iron for IV administration, which require multiple doses. Protocols are commonly used with other IV irons, but there are limited Canadian data for FDI, and no protocol exists. Objectives To evaluate the efficacy and safety of FDI for patients with CKD and to ascertain information related to its use in Canadian provinces. Methods This retrospective cohort study involved patients with non-dialysis-dependent CKD (NDD-CKD) and patients undergoing peritoneal dialysis (PD) who received FDI in a tertiary hospital in Nova Scotia between June 2020 and May 2021. Each patient was followed for a minimum of 6 months. The efficacy outcomes were the changes from baseline in hemoglobin, transferrin saturation (TSAT), and ferritin after the first dose of FDI and at 3 and 6 months. The safety outcomes were the frequency and types of adverse reactions to FDI. Electronic surveys were sent to 33 Canadian renal pharmacists to gather information about FDI use, dosing, administration, monitoring, funding, and safety in their respective organizations. Results A total of 52 infusions were administered to 35 patients during the study period. The median times between doses 1 and 2 and between doses 2 and 3 were 19.1 and 6.6 weeks, respectively. The median change from baseline to first post-FDI follow-up blood work was significant for hemoglobin (9.0 g/L, p = 0.023), TSAT (11 percentage points, p < 0.001), and ferritin (271.4 μg/L, p < 0.001). Median darbepoetin doses decreased from baseline to 6 months (p < 0.001). Three adverse reactions occurred. At least 15 (65%) of the 23 survey respondents reported that FDI was funded by their province or was listed on their hospital drug formulary. Conclusion This study provides evidence that FDI is an effective and safe treatment for anemia in NDD-CKD and PD patients.

Markers of Oxidative Stress, Inflammation and Endothelial Function following High-Dose Intravenous Iron in Patients with Non-Dialysis-Dependent Chronic Kidney Disease-A Pooled Analysis.

Abstract
Chronic kidney disease (CKD) represents a state of oxidative stress imbalance, which is potentially amplified by iron deficiency. Intravenous iron is considered safe and efficacious in the treatment of iron deficiency anemia, however, concerns remain regarding its potential pro-oxidant effect, leading to inflammatory and endothelial consequences. This pooled analysis of two pilot randomized controlled trials aimed to group and analyze the potential effect of high-dose intravenous iron (ferric derisomaltose, 1000 mg) on markers of oxidative stress (thiobarbituric acid reactive substance), inflammation (C-reactive protein, interleukins 6 and 10) and endothelial response (E-selectin, P-selectin) in patients with non-dialysis-dependent CKD and iron deficiency with/without anemia. Pulse wave velocity as a surrogate measure of arterial stiffness was measured. Thirty-six patients were included. No statistically significant trend was identified for any of the aforementioned markers. Stratification and comparison of data based on CKD stage did not yield statistically significant trajectories with the exception of the C-reactive protein in CKD stage 3b. These results suggest that high-dose intravenous iron does not impact measures of oxidative stress or inflammation; however, the results are not conclusive. Further research in a larger cohort is necessary to characterize the effect of intravenous iron on oxidative status and inflammation and its potential sequela in CKD.

Abstract
Anemia is a common complication of chronic kidney disease (CKD). The insufficient erythropoietin (EPO) production by the kidneys and iron deficiency are the main causes. Iron supplementation and the administration of recombinant EPO are the main treatment modalities. New iron formulations that can be administered orally, intravenously or directly via the dialysate have recently been developed to improve efficacy and tolerance. Ferric citrate administered orally can effectively corrects anemia in case of iron deficiency and in addition chelate phosphate in the gut lumen. Ferric carboxymaltose allows intravenous administration of larger doses given less frequently. Ferric pyrophosphate citrate administered directly via the dialysate allows the compensation of iron losses during the hemodialysis session. HIF-prolyl-hydroxylase inhibitors are a new therapeutic class of erythropoiesis-stimulating agents. Orally administered, they act by stabilizing the HIF transcription factor involved in the initiation of erythropoietin production by hypoxia. Several clinical studies have recently evaluated these new molecules in comparison with recombinant EPO. In CKD patients not yet on dialysis or undergoing dialysis therapy non-inferiority in correcting anemia has been demonstrated compared with recombinant EPO. The decrease in circulating hepcidin they induce appears greater than that induced by injectable recombinant EPO. Presently available reports on the safety of HIF-prolyl-hydroxylase inhibitors are reassuring but need to be confirmed in longer-term studies of larger size. © 2022 Published by Elsevier Masson SAS on behalf of Société francophone de néphrologie, dialyse et transplantation.

Abstract
BACKGROUND Iron deficiency anemia (IDA) is common during pregnancy and associated with adverse maternal and neonatal outcomes. Treatment with iron supplementation is recommended during pregnancy, but the optimal delivery route is unclear. Oral iron risks has high risk of gastrointestinal side effects and low absorption. Intravenous iron is infused directly but is expensive. The American College of Obstetricians and Gynecologists currently recommends oral iron to treat IDA in pregnancy with intravenous iron reserved as second-line therapy, if needed. This approach is associated with persistent anemia, increasing the risk of peripartum blood transfusion. We aim to provide data on optimal route of iron repletion for IDA in pregnancy. METHODS In IVIDA2, a double-blind, placebo controlled, multicenter randomized trial in the United States, 746 pregnant people with moderate-to-severe IDA (hemoglobin <10 g/dL and ferritin <30 ng/mL) at 24-28 weeks' gestation will be randomized 1:1 to either a single 1000 mg dose of intravenous ferric derisomaltose and oral placebo (1-3 times daily) or a single placebo infusion with 1-3 times daily 325 mg ferrous sulfate (65 mg elemental iron) tablet. The primary outcome is peripartum blood transfusion (blood transfusion from delivery to 7 days postpartum). Secondary outcomes include adverse medication reactions, maternal and neonatal hematologic indices, and offspring neurodevelopment.

Abstract
Ferric derisomaltose (FDI; Monofer) is used in clinical practice to treat iron deficiency, but the safety and efficacy of FDI has not been robustly evaluated in a large real-world study. This retrospective, multicentre, audit-based, observational study provides pragmatic information about safety and clinical responses with FDI across therapy areas and patient populations, helping to facilitate treatment decisions. Participating sites provided data from the medical records of adults who had received ≥ 1 FDI infusion. The primary outcome was the incidence of adverse reactions within 24 hours of the FDI infusion. Secondary outcomes included the change from baseline in haemoglobin and ferritin up to 12 months post infusion. In total, 19 sites provided data for a total of 7354 FDI-treated patients; 64.3% of patients were female, and 42.2% were aged ≥ 70 years. Surgery was the main hospital specialty (34.5%). The incidence of any recorded adverse reactions, hypersensitivity reactions, and anaphylaxis were 1.7%, 0.4%, and < 0.1%, respectively, regardless of baseline anaemia status. Statistically significant increases in haemoglobin and ferritin were observed between baseline and Month 4 following FDI treatment (p < 0.0001). Improvements in haemoglobin were more pronounced for hospital specialties where operative blood loss is expected (surgery/obstetrics) compared with those where blood loss is not expected. This study provides real-world clinical evidence for the low risk of adverse reactions with FDI across diverse patient populations, providing reassurance that intravenous iron is not associated with serious toxicity. These findings may inform changes in intravenous iron delivery to provide effective therapy to more patients in need.

Abstract
Fatigue is a common, non-specific symptom that often impairs patients’ quality of life. Even though fatigue may be the first symptom of many serious diseases, it is often underestimated due to its non-specific nature. Iron metabolism disorders are a prominent example of conditions where fatigue is a leading symptom. Whether it is an iron deficiency or overload, tiredness is one of the most common features. Despite significant progress in diagnosing and treating iron pathologies, the approach to chronic fatigue syndrome in such patients is not precisely determined. Our study aims to present the current state of knowledge on fatigue in patients with deteriorated iron metabolism.

Abstract
Iron deficiency commonly affects patients with chronic kidney disease and has an important burden in disease trajectory and quality of life; nonetheless current guidelines do not advocate treatment of iron-deficiency without anemia in this patient group. Concerns exist regarding the potential effects of intravenous iron on oxidative stress, inflammation, and endothelial function. As part of a multicenter double-blinded randomized controlled clinical trial, we examined the effects of a single dose of intravenous iron vs. placebo on biomarkers of oxidative stress, inflammation and endothelial function in non-anemic iron deficient patients (serum ferritin < 100 μg/L and/or transferrin saturation < 20%) with chronic kidney disease (stage 3b-5). Fifty-four individuals were randomized to receive ferric derisomaltose (n = 26) or placebo (n = 28). Ferric derisomaltose was associated with a non-significant decrease in mean F2-isoprostane and no effect on thiobarbituric acid reactive substances when compared to placebo throughout follow up. No effect on inflammatory markers was observed. A modest but statistically significant rise in E-selectin was noted in the intravenous iron group at 1 month and 3 month follow-up (p = 0.030 and p = 0.002 respectively). These results suggest ferric derisomaltose administration in non-dialysis dependent chronic kidney disease patients who are iron deficient does not induce prolonged oxidative stress or inflammation. Larger trials are required to quantify the benefit of intravenous iron administration in this patient group.

Abstract
Chronic kidney disease (CKD) leads to alterations of iron metabolism, which contribute to the development of anemia and necessitates iron supplementation in patients with CKD. Elevated hepcidin accounts for a significant iron redistribution in CKD. Recent data indicate that these alterations in iron homeostasis coupled with therapeutic iron supplementation have pleiotropic effects on many organ systems in patients with CKD, far beyond the traditional hematologic effects of iron; these include effects of iron on inflammation, oxidative stress, kidney fibrosis, cardiovascular disease, CKD-mineral and bone disorder, and skeletal growth in children. The effects of iron supplementation appear to be largely dependent on the route of administration and on the specific iron preparation. Iron-based phosphate binders exemplify the opportunity for using iron for both traditional (anemia) and novel (hyperphosphatemia) indications. Further optimization of iron therapy in patients with CKD may inform new approaches to the treatment of CKD complications and potentially allow modification of disease progression.

Abstract
CONTEXT Hypophosphatemia, osteomalacia, and fractures are complications of certain intravenous iron formulations. OBJECTIVE This study investigated risk factors for incident, severe, and persistent hypophosphatemia, and associated alterations in bone and mineral biomarkers following intravenous iron treatment. METHODS We analyzed data from the PHOSPHARE-IDA randomized clinical trials, comprising 245 patients aged 18 years or older with iron deficiency anemia at 30 outpatient clinics in the United States who received intravenous ferric carboxymaltose (FCM) or ferric derisomaltose (FDI). Outcome measures included serum phosphate, intact fibroblast growth factor-23 (iFGF23), 1,25-dihydroxyvitamin D (1,25(OH)2D), ionized calcium, parathyroid hormone (PTH), and alkaline phosphatase. RESULTS FCM was the only consistent risk factor for incident hypophosphatemia (< 2.0 mg/dL; odds ratio vs FDI: 38.37; 95% CI: 16.62, 88.56; P < 0.001). Only FCM-treated patients developed severe hypophosphatemia (< 1.0 mg/dL; 11.3%; 13/115) or persistent hypophosphatemia (< 2.0 mg/dL at study end; 40.0%; 46/115). More severe hypophosphatemia associated with significantly greater increases in iFGF23, PTH, and alkaline phosphatase, and more severe decreases in 1,25(OH)2D and ionized calcium (all P < 0.05). Patients with persistent vs resolved hypophosphatemia demonstrated significantly greater changes in iFGF23, PTH, 1,25(OH)2D, and N-terminal procollagen-1 peptide levels (all P < 0.01), but alkaline phosphatase increased similarly in both groups. CONCLUSION Treatment with FCM was the only consistent risk factor for hypophosphatemia. Patients who developed severe or persistent hypophosphatemia after FCM treatment manifested more severe derangements in bone and mineral metabolism. Changes in bone biomarkers continued beyond resolution of hypophosphatemia, suggesting ongoing effects on bone that may help explain the association of FCM with osteomalacia and fractures.

Abstract
WHAT IS KNOWN AND OBJECTIVE To evaluate the efficacy and safety of intravenous iron supplementation in patients with renal anaemia. METHODS We searched the PubMed, Embase, Cochrane Library, and Web of Science from their inception until 17 September 2021, for randomized controlled trials (RCTs) to evaluate the efficacy and safety of intravenous iron at different frequencies. The observed efficacy indicators included transfer saturation (TSAT), serum ferritin (SF) and haemoglobin (HGB). Outcomes of interest included allergies, infections, all-cause mortality and cardiovascular events. RESULTS AND DISCUSSION Of the 751 eligible studies, 7 RCTs met the inclusion criteria. The RCTs showed that there were no significant differences between the low-frequency high-dose group (1-2 doses, >200 mg/dose) and the high-frequency low-dose group (4-5 doses, ≤200 mg/dose) in the increase in TSAT (WMD = 1.90; 95% CI = -2.04 to 5.84; I2 = 0%), SF (WMD = 15.70; 95% CI = -32.20 to 70.61; I2 = 0%) and HGB (WMD = -0.00; 95% CI = -0.43 to 0.42; I2 = 0%). There was also no significant difference in the occurrence of outcome events, including allergies (RR = 1.84; 95% CI = 0.95 to 3.57; I2 = 45%), infections (RR = 0.61; 95% CI = 0.20-1.86; I2 = 0%), cardiovascular events (RR = 0.88; 95% CI = 0.67-1.15; I2 = 48%) and all-cause mortality (RR = 0.74; 95% CI = 0.40-1.35; I2 = 0%). WHAT IS NEW AND CONCLUSION Frequencies of intravenous iron supplementation with similar doses share similar safety and efficacy in patients with renal anaemia. However, a single dose or two doses of intravenous iron are more cost-effective and patient friendly. These findings may provide evidence for the clinical application of intravenous iron supplementation for patients with renal anaemia.

Abstract
In 1996, the National Health Insurance Administration of Taiwan applied a restrictive reimbursement criteria for erythropoiesis-stimulating agents (ESAs) use in patients with chronic kidney disease. The maximal ESAs dosage allowed by insurance is capped at 20,000 U of epoetin per month. Nephrologists avoided the use of high ESA dosages to achieve a hemoglobin level of 10–11 g/dL using iron supplementation. We assessed the association of anemia and iron parameters with mortality among peritoneal dialysis (AIM-PD) patients. A retrospective cohort study was conducted based on the Taiwan Renal Registry Data System. From January 1, 2000 to December 31, 2008, we enrolled 4356 well-nourished PD patients who were older than 20 years and had been receiving PD for more than 12 months. All patients were divided into subgroups according to different hemoglobin, ferritin and transferrin saturation (TSAT) values. Patients were followed until death or December 31, 2008. In a median 2.9-year study period, 694 (15.9%) patients died. By multivariate adjustment, a hemoglobin level lower than 10 g/dL was significantly associated with a higher risk for all-cause and cardiovascular deaths. Moreover, a serum ferritin level higher than 800 ng/mL was associated with a higher risk for all-cause deaths, and a TSAT value between 20 and 50% was associated with the lowest all-cause mortality. In conclusions, we recommend avoiding a low hemoglobin level and a serum ferritin level of more than 800 ng/mL and maintaining a TSAT value between 20 and 50%, as these conditions were associated with lower risks of all-cause mortality in the AIM-PD study.

Abstract
INTRODUCTION Intravenous (IV) iron is the preferred treatment for patients with iron deficiency anemia (IDA) who require rapid replenishment of iron stores or in whom oral iron is not tolerated or effective. Data from two large-scale randomized controlled trials (RCTs) have recently been published reporting the incidence of adjudicated cardiovascular events after ferric derisomaltose (FDI) and iron sucrose (IS). The objective was to calculate the relative incidence of cardiovascular events with FDI and IS, and to conduct an indirect comparison with ferric carboxymaltose (FCM) based on previously published studies of cardiovascular risk. METHODS RCTs reporting the incidence of blindly adjudicated cardiovascular events in IDA patients treated with IV iron were identified by systematic literature review (SLR). Pairwise random effects meta-analyses of FDI versus IS, and FCM versus IS were conducted for the pre-specified adjudicated composite cardiovascular endpoint of: death due to any cause, nonfatal myocardial infarction, nonfatal stroke, unstable angina requiring hospitalization, congestive heart failure, arrhythmia, and protocol-defined hypertensive and hypotensive events. Analyses were also conducted for the composite endpoint excluding blood pressure events. Meta-analysis results were combined in an adjusted indirect comparison to provide an indirect estimate of cardiovascular risk with FDI versus FCM. RESULTS The SLR retrieved 694 unique articles, of which four were RCTs reporting the incidence of the composite cardiovascular endpoint; two studies comparing FCM (N = 1529) with IS (N = 1505), and two studies comparing FDI (N = 2008) with IS (N = 1000). The odds ratios of the composite CV endpoint were 0.59 (95% confidence interval: 0.39-0.90) for FDI versus IS, 1.12 (95% CI 0.90-1.40) for FCM versus IS, and the indirect OR for FDI versus FCM was 0.53 (95% CI 0.33-0.85). CONCLUSIONS Pooling data from four large-scale RCTs suggested that FDI was associated with significantly lower incidence of cardiovascular adverse events compared to both FCM and IS.

Abstract
OBJECTIVES Two intravenous (IV) iron formulations, ferric derisomaltose (FDI) and iron sucrose (IS), are currently available for the treatment of iron deficiency anemia (IDA) in China. Clinical studies have demonstrated that FDI has an improved efficacy and safety profile versus IS, while requiring fewer infusions to correct iron deficits. Based on these findings, the present study evaluated the costs and benefits of FDI and IS for the treatment of IDA, from a healthcare system and societal perspective in China. METHODS A patient-level model was developed to project time to hematological response and incidence of cardiovascular adverse events and hypersensitivity reactions (HSRs) associated with FDI and IS over 5 years. Costs included iron acquisition, administration, and adverse event/HSR treatment costs, based on published studies, fee schedules, and a physician survey. Health state utilities associated with adverse events, HSRs, and the number of infusions were obtained from the literature and a time trade-off survey. RESULTS From a healthcare system perspective, FDI was associated with incremental costs of RMB 1,934 (purchasing power parity USD 462) and incremental quality-adjusted life expectancy of 0.078 quality-adjusted life-years (QALYs) versus IS, yielding an incremental cost-utility ratio of RMB 24,901 (USD 5,949) in the base case scenario. From a societal perspective, FDI was associated with reduced total costs and therefore dominant versus IS. LIMITATIONS Limitations included the absence of clinical data specific to China and insufficient data to model persistence with treatment. CONCLUSIONS This was the first cost-utility analysis comparing FDI and IS for the treatment of IDA in China. Based on a patient-level model, FDI was found to improve quality of life and reduce administration and adverse events costs relative to IS. Using the 2020 Chinese gross domestic product per capita of RMB 72,447 (USD 17,307) as a cost-effectiveness threshold, FDI would be considered cost-effective in China.

Abstract
Iron deficiency commonly contributes to the anemia affecting individuals with chronic kidney disease. Diagnostic criteria for iron deficiency in chronic kidney disease are explained. Mechanisms of functional and absolute iron deficiency and general treatment Principles as delineated in the Kidney Disease: Improving Global Outcomes guidelines are reviewed. Repletion of absolute iron deficits has progressed over time with the addition of better tolerated, more effective oral agents including ferric citrate, ferric maltol, and sucrosomial iron. Structural characteristics and trial data enabling regulatory approval of these novel oral agents are examined. Newer intravenous iron therapies including ferric carboxymaltose and ferric derisomaltose allow for fewer infusions and decreased risk of serious hypersensitivity reactions. Concerns about adverse events including cardiovascular events and infections are discussed. The potential risk of 6H syndrome due to these intravenous agents, including hypophosphatemia, osteomalacia, and pathologic fractures is emphasized. The proposed pathophysiology of 6H syndrome and hypophosphatemia is described. Ferric pyrophosphate citrate enables administration of iron for repletion through dialysate. Relative merits, costs, and risks of various iron agents such as hypersensitivity and 6H syndrome/hypophosphatemia are summarized.

Abstract
BACKGROUND AND OBJECTIVES Whether iron supplementation in patients on hemodialysis could be delivered by less frequent but higher single doses compared with the currently more common higher-frequency schedules of lower single iron doses is unknown. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We carried out an open-label, randomized, controlled noninferiority trial over 40 weeks in patients on prevalent hemodialysis (n=142). We administered in total 2 g iron as 100 mg iron sucrose biweekly in a continuous (20 × 100 mg) fashion or 500 mg ferric carboxymaltose every 10 weeks in a periodic (4 × 500 mg) fashion. The primary end point was the change in hemoglobin at week 40 from baseline with a noninferiority margin of -0.8 g/dl. Secondary end points were changes in ferritin, transferrin, transferrin saturation, and erythropoiesis-stimulating agent use. RESULTS In total, 108 patients completed the study. At 40 weeks, hemoglobin changed by -0.27 g/dl (95% confidence interval, -0.64 to 0.09) in the iron sucrose arm and by -0.74 g/dl (95% confidence interval, -1.1 to -0.39) in the ferric carboxymaltose arm compared with baseline. Noninferiority was not established in the per-protocol population as hemoglobin changes compared with baseline differed by -0.47 g/dl (95% confidence interval, -0.95 to 0.01) in the ferric carboxymaltose arm compared with the iron sucrose arm. Proportional changes from baseline to week 40 differed by -31% (98.3% confidence interval, -52 to -0.1) for ferritin, by 1% (98.3% confidence interval, -7 to 10) for transferrin, and by -27% (98.3% confidence interval, -39 to -13) for transferrin saturation in the ferric carboxymaltose arm compared with the iron sucrose arm. Erythropoiesis-stimulating agent dosing did not differ between groups. The overall number of adverse events was similar; however, more infections were observed in the iron sucrose arm. CONCLUSIONS An equal cumulative dose of ferric carboxymaltose administered less frequently did not meet noninferiority for maintaining hemoglobin levels compared with iron sucrose administered more frequently.

Safety and Efficacy of Intravenous Ferric Derisomaltose Compared to Iron Sucrose for Iron Deficiency Anemia in Patients with Chronic Kidney Disease With and Without Heart Failure. Am J Cardiol 2021; 152:138-145. [PMID: 34162484 DOI: 10.1016/j.amjcard.2021.04.042] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/05/2021] [Revised: 04/13/2021] [Accepted: 04/16/2021] [Indexed: 11/23/2022]
Abstract
Ferric derisomaltose (FDI) is an intravenous (IV) high-dose iron formulation approved in the US for the treatment of iron deficiency anemia in adults who are intolerant of/have had an unsatisfactory response to oral iron, or who have non-dialysis-dependent chronic kidney disease (NDD-CKD). FERWON-NEPHRO was a randomized, open-label, multicenter clinical trial evaluating the safety and efficacy of a single infusion of FDI 1,000 mg versus up to 5 doses of iron sucrose (IS) 200 mg (recommended cumulative dose, 1,000 mg) over 8 weeks in patients with NDD-CKD and iron deficiency anemia. Of 1,525 patients included in the safety analysis, 244 (16%) had a history of heart failure (HF). Overall, the rate of serious or severe hypersensitivity reactions was low and did not differ between treatment groups. Cardiovascular adverse events (AEs) were reported for 9.4% of patients who had HF and 4.2% who did not. Time to first cardiovascular AE was longer following administration of FDI compared with IS (hazard ratio: 0.59 [95% CI: 0.37, 0.92]; p=0.0185), a difference that was similar in patients with or without HF (p=0.908 for interaction). Patients achieved a faster hematological response (assessed by changes in hemoglobin and ferritin concentrations, and increase in transferrin saturation) with FDI versus IS. In conclusion, in patients with NDD-CKD, a single infusion of FDI was safe, well tolerated, and was associated with fewer cardiovascular AEs and a faster hematological response, compared to multiple doses of IS. These effects were similar for patients with and without HF.

Abstract
BACKGROUND Approximately 30%-45% of patients with nondialysis CKD have iron deficiency. Iron therapy in CKD has focused primarily on supporting erythropoiesis. In patients with or without anemia, there has not been a comprehensive approach to estimating the association between serum biomarkers of iron stores, and mortality and cardiovascular event risks. METHODS The study included 5145 patients from Brazil, France, the United States, and Germany enrolled in the Chronic Kidney Disease Outcomes and Practice Patterns Study, with first available transferrin saturation (TSAT) and ferritin levels as exposure variables. We used Cox models to estimate hazard ratios (HRs) for all-cause mortality and major adverse cardiovascular events (MACE), with progressive adjustment for potentially confounding variables. We also used linear spline models to further evaluate functional forms of the exposure-outcome associations. RESULTS Compared with patients with a TSAT of 26%-35%, those with a TSAT ≤15% had the highest adjusted risks for all-cause mortality and MACE. Spline analysis found the lowest risk at TSAT 40% for all-cause mortality and MACE. Risk of all-cause mortality, but not MACE, was also elevated at TSAT ≥46%. Effect estimates were similar after adjustment for hemoglobin. For ferritin, no directional associations were apparent, except for elevated all-cause mortality at ferritin ≥300 ng/ml. CONCLUSIONS Iron deficiency, as captured by TSAT, is associated with higher risk of all-cause mortality and MACE in patients with nondialysis CKD, with or without anemia. Interventional studies evaluating the effect on clinical outcomes of iron supplementation and therapies for alternative targets are needed to better inform strategies for administering exogenous iron.

Abstract
Intravenous (IV) iron is the therapy of choice when oral iron is ineffective or poorly tolerated, yet use has been limited by fears of hypersensitivity reactions (HSRs). Newer formulations that bind iron more tightly and release it more slowly have made the risk of serious or severe HSRs very low. One such formulation, ferric derisomaltose, has been approved in the United States for delivery of 1000 mg iron in a single IV infusion. Ferric derisomaltose rapidly repletes iron parameters with low rates of serious or severe HSRs. Single-infusion iron repletion offers convenience, eliminates adherence concerns, and reduces healthcare resource utilization.

Abstract
In chronic kidney disease, anemia and disordered iron homeostasis are prevalent and associated with significant adverse consequences. In 2012, Kidney Disease: Improving Global Outcomes (KDIGO) issued an anemia guideline for managing the diagnosis, evaluation, and treatment of anemia in chronic kidney disease. Since then, new data have accrued from basic research, epidemiological studies, and randomized trials that warrant a re-examination of previous recommendations. Therefore, in 2019, KDIGO decided to convene 2 Controversies Conferences to review the latest evidence, explore new and ongoing controversies, assess change implications for the current KDIGO anemia guideline, and propose a research agenda. The first conference, described here, focused mainly on iron-related issues, including the contribution of disordered iron homeostasis to the anemia of chronic kidney disease, diagnostic challenges, available and emerging iron therapies, treatment targets, and patient outcomes. The second conference will discuss issues more specifically related to erythropoiesis-stimulating agents, including epoetins, and hypoxia-inducible factor-prolyl hydroxylase inhibitors. Here we provide a concise overview of the consensus points and controversies resulting from the first conference and prioritize key questions that need to be answered by future research.

Abstract
Introduction: The newest intravenous (IV) iron products show an improved safety profile over predecessors, allowing for the rapid administration of relatively high doses. Ferric derisomaltose (FDI; also known as iron isomaltoside), ferric carboxymaltose (FCM), and ferumoxytol (FER), are successful treatments for iron deficiency (Europe; FDI and FCM) and iron deficiency anemia (US; FDI, FCM, and FER).Areas covered: This review focusses on the chemistry and structure of FDI, FCM, and FER, and on three key aspects of IV iron safety: (1) hypersensitivity; (2) hypophosphatemia and sequelae; (3) cardiovascular safety.Expert opinion: Although the safety of modern IV iron has improved, immediate infusion reactions and the development of hypophosphatemia must be appreciated and recognized by those who prescribe and administer IV iron. Immediate infusion reactions can occur with any IV iron and are usually mild; severe reactions - particularly anaphylaxis - are extremely rare. The recognition and appropriate management of infusion reactions is an important consideration to the successful administration of IV iron. Severe, persistent, hypophosphatemia is a specific side effect of FCM. No cardiovascular safety signal has been identified for IV iron. Ongoing trials in heart failure will provide additional long-term efficacy and safety data.

Kassianides X, Gordon A, Sturmey R, Bhandari S. The comparative effects of intravenous iron on oxidative stress and inflammation in patients with chronic kidney disease and iron deficiency: a randomized controlled pilot study. Kidney Res Clin Pract 2021; 40:89-98. [PMID: 33745264 PMCID: PMC8041632 DOI: 10.23876/j.krcp.20.120] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Accepted: 08/25/2020] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND Concerns exist regarding the pro-oxidant and inflammatory potential of intravenous (IV) iron due to labile plasma iron (LPI) generation. This IRON-CKD trial compared the effects of different IV irons on oxidative stress and inflammation. METHODS In this randomized open-label explorative single-center study in the United Kingdom, non-dialysis-dependent chronic kidney disease (CKD) patients with iron deficiency were randomized (1:1:1:1) to receive a single infusion of 200 mg iron dextran, or 200 mg iron sucrose (IS), or 200 mg or 1,000 mg ferric derisomaltose (FDI) and were followed up for 3 months. The primary outcomes measured were induction of oxidative stress and inflammation. Secondarily, efficacy, vascular function, quality of life, and safety were monitored. RESULTS Forty patients were enrolled. No significant rise in oxidative stress existed, regardless of preparation or dose. There was a significant rise in LPI with 1,000 mg FDI at 2 hours that normalized within a week, not impacting oxidative stress or inflammation. A delayed rise in C-reactive protein was noted with IS. High-dose FDI produced a sustained serum ferritin increase (mean ± standard error of the mean of predose: 69.1 ± 18.4 μg/L, 3 months: 271.0 ± 83.3 μg/L; p = 0.007). Hemoglobin remained stable throughout. No adverse drug reactions were recorded during the study. CONCLUSION A single dose of IV iron in CKD patients does not trigger oxidative stress or inflammation biomarkers. Third-generation IV irons have a reassuring safety profile, and high-dose FDI produced a sustained serum ferritin rise and more efficient iron repletion, with no significant pro-oxidant or inflammatory signals when compared to a lower dose and other IV irons.

Abstract
This work presents an update on the management of iron deficiency in patients with chronic kidney disease (CKD), either with or without anaemia. A review is made of the recommendations of the guidelines for the treatment of iron deficiency in CKD. It also presents new studies on iron deficiency in patients with CKD, as well as new findings about iron therapy and its impact on clinical outcomes. Anaemia is a common complication of CRF, and is associated with a decrease in the quality of life of the patients, as well as an increase in morbidity and mortality. Iron deficiency (absolute or functional) is common in non-dialysis chronic kidney disease patients, and may cause anaemia or a low response to erythropoiesis-stimulating agents. For this reason, the clinical guidelines for the treatment of the anaemia in Nephrology indicate the correction of the deficiency in the presence of anaemia. Iron replacement therapy is indicated in patients with CKD and anaemia (Hb < 12 g/dl) in accordance with the guidelines. There is no unanimity in the indication of iron replacement therapy in patients with Hb > 12 g/dl, regardless of whether they have an absolute or functional iron deficiency. Intravenous iron replacement therapy is safe, more efficient and rapid than oral therapy for achieving an increase haemoglobin lels and reducing the dose of erythropoiesis-stimulating agents. For the administration of intravenous iron in non-dialysis chronic renal failure patients a strategy of high doses and low frequency would be preferred on being more convenient for the patient, preserves better the venous capital, and is safe and cost-effective. Iron plays an essential role in energy metabolism and other body functions beyond the synthesis of haemoglobin, for which the iron deficiency, even in the absence of anaemia, could have harmful effects in patients with CKD. The correction of the iron deficiency, in the absence of anaemia is associated with functional improvement in patients with heart failure, and in muscle function or fatigue in patients without CKD. Despite the evidence of benefits in the correction of iron deficiency in patients with CKD, more studies are required to evaluate the impact of the correction of the iron deficiency in the absence of anaemia on morbidity and mortality, quality of life and physical capacity, as well as the long-term effect of oral and intravenous iron replacement therapy in this population.

Abstract
Third-generation intravenous (i.v.) iron preparations are safe and efficacious and are increasingly used in the treatment of iron-deficiency anaemia. Hypophosphataemia is emerging as an established side-effect following the administration of certain compounds. Symptoms of hypophosphataemia can be masked by their similarity to those of iron-deficiency anaemia and both acute and chronic hypophosphataemia can be detrimental. Hypophosphataemia appears to be linked to imbalances in the metabolism of the phosphatonin fibroblast growth factor 23. In this narrative review, we discuss the possible pathophysiology behind this phenomenon, the studies comparing third-generation i.v. iron compounds, and the potential implications of the changes in fibroblast growth factor 23 and hypophosphataemia. We also present an algorithm of how to approach such patients requiring i.v. iron in anticipation of hypophosphataemia and how the impact related to it can be minimized.

Abstract
During 2020, COVID-19 or CoV2-SARS dominated the public and medical community's discourse, thus prompting a preponderance of COVID-driven research. Despite the many resulting studies, few new insights emerged regarding blood components and blood treatments, the focus of this chapter. The pandemic led to a resurgence of interest in convalescent plasma and, by extension, freeze-dried plasma as treatment options for Coronavirus. Several such studies are summarized. Other research topics include blood coagulation, treatments for iron deficiency anemia, and newly diagnosed multiple myeloma. While this volume is devoted to exploring and reporting pharmacological side effects, most studies detailed few significant adverse events.

Abstract
Introduction: Originally approved in Europe in 2009, ferric derisomaltose is the most recently authorized intravenous iron compound in the United States of America (2020). Ferric derisomaltose given as a rapid high-dose infusion can allow complete iron repletion in a single dose and it is now widely used in the treatment of iron deficiency. Areas covered: The chemistry, pharmacodynamics and pharmacokinetics of ferric derisomaltose are reviewed. Results from phase II, III and IV trials regarding efficacy and safety are presented. Mechanisms behind minor infusion reactions, hypersensitivity and hypophosphatemia are discussed. The economic impact of ferric derisomaltose use is presented. Data pertaining to the use of ferric derisomaltose in iron deficiency anemia, chronic kidney disease, inflammatory bowel disease, chronic heart failure, perioperative care and other patient groups are comprehensively covered. Expert opinion: Ferric derisomaltose is an effective intravenous iron formulation with a good safety profile, providing rapid, cost-effective iron repletion. Ferric derisomaltose releases low quantities of labile iron relative to older compounds. Anaphylaxis is extremely rare, and 'Fishbane' reactions are uncommon. Hypophosphatemia following ferric derisomaltose administration is infrequent in comparison to other intravenous irons such as ferric carboxymaltose. The scope of ferric derisomaltose use is growing with increasing research in these areas.

Abstract
Background Intravenous iron is often used to treat iron deficiency anaemia in non-dialysis chronic kidney disease (ND-CKD), but the optimal dosing regimen remains unclear. We evaluated the impact of high- versus low-dose intravenous iron isomaltoside on the probability of retreatment with intravenous iron in iron-deficient ND-CKD patients. Methods This real-world, prospective, observational study collected data from 256 ND-CKD patients treated for anaemia in the UK. Following an initial course of iron isomaltoside, patients were followed for ≥12 months. Iron dose and the need for retreatment were determined at the investigators’ discretion. The primary study outcome was the need for retreatment at 52 weeks compared between patients who received >1000 mg of iron during Course 1 and those who received ≤1000 mg. Safety was evaluated through adverse drug reactions. Results The probability of retreatment at Week 52 was significantly lower in the >1000 mg iron group (n = 58) versus the ≤1000 mg group (n = 198); hazard ratio (95% confidence interval [CI]): 0.46 (0.20, 0.91); p = 0.012. Mean (95% CI) haemoglobin increased by 6.58 (4.94, 8.21) g/L in the ≤1000 mg group and by 10.59 (7.52, 13.66) g/L in the >1000 mg group (p = 0.024). Changes in other blood and iron parameters were not significantly different between the two groups. Administering >1000 mg of iron isomaltoside saved 8.6 appointments per 100 patients compared to ≤1000 mg. No serious adverse drug reactions were reported. Of the patients who received ≤1000 mg of iron in this study, 82.3% were eligible for a dose >1000 mg. Conclusions The >1000 mg iron isomaltoside regimen reduced the probability of retreatment, achieved a greater haemoglobin response irrespective of erythropoiesis-stimulating agent treatment, and reduced the total number of appointments required, compared to the ≤1000 mg regimen. Many of the patients who received ≤1000 mg of iron were eligible for >1000 mg, indicating that there was considerable underdosing in this study.

Abstract
Aims Hypophosphataemia is an increasingly recognized side‐effect of ferric carboxymaltose (FCM) and possibly iron isomaltoside/ferric derisomaltose (IIM), which are used to treat iron deficiency. The aim of this study was to determine frequency, severity, duration and risk factors of incident hypophosphataemia after treatment with FCM and IIM. Methods A systematic literature search for articles indexed in EMBASE, PubMed and Web of Science in years 2005–2020 was carried out using the search terms ‘ferric carboxymaltose’ OR ‘iron isomaltoside’. Prospective clinical trials reporting outcomes on hypophosphataemia rate, mean nadir serum phosphate and/or change in mean serum phosphate from baseline were selected. Hypophosphataemia rate and severity were compared for studies on IIM vs. FCM after stratification for chronic kidney disease. Meta‐regression analysis was used to investigate risk factors for hypophosphataemia. Results Across the 42 clinical trials included in the meta‐analysis, FCM induced a significantly higher incidence of hypophosphataemia than IIM (47%, 95% CI 36–58% vs. 4%, 95% CI 2–5%), and significantly greater mean decreases in serum phosphate (0.40 vs. 0.06 mmol/L). Hypophosphataemia persisted at the end of the study periods (maximum 3 months) in up to 45% of patients treated with FCM. Meta‐regression analysis identified low baseline serum ferritin and transferrin saturation, and normal kidney function as significant predictors of hypophosphataemia. Conclusion FCM is associated with a high risk of hypophosphataemia, which does not resolve for at least 3 months in a large proportion of affected patients. More severe iron deficiency and normal kidney function are risk factors for hypophosphataemia.

Abstract
Introduction: Iron-deficiency anemia in chronic kidney disease (CKD) is common and has prognostic, financial, and quality of life implications. Intravenous (IV) iron is a key intervention for optimal management, however, ongoing safety concerns exist. Area covered: The potential side effects associated with IV iron use are addressed as we review the most recent studies. Hypersensitivity reactions and true anaphylaxis are indeed rare with a greater understanding of the nature of labile iron and 'Fishbane' reactions. Hypophosphatemia appears commoner with certain IV iron preparations, however its significance in CKD requires exploration. The long-standing questions regarding oxidative stress and the potential susceptibility to infections and worsening cardiovascular morbidity are discussed. Iron overload secondary to repeat IV iron infusions is plausible, however, a number of guidelines limit and strictly guide prescription. Expert opinion: The past decade has improved our understanding of IV iron administration safety in patients with CKD. Third generation IV iron compounds have minimized hypersensitivity reactions while allowing high doses to be administered safely and rapidly in non-dialysis-dependent CKD patients. However, differences in safety profiles such as hypophosphatemia require further study and therapy should be tailored to the individual. Clinicians should feel confident in using IV iron therapy.

Abstract
BACKGROUND Iron deficiency is common in pregnancy. If left untreated, iron deficiency can lead to iron deficiency anaemia, which is a condition related to maternal and neonatal morbidity. The prevalence of iron deficiency increases through the trimesters, which means that women with iron deficiency in the beginning of pregnancy also have a great risk of developing iron deficiency anaemia during pregnancy. Standard treatment is oral iron in individualised intensified doses based on screening values in 1st trimester. Maternal symptoms of iron deficiency and iron deficiency anaemia include fatigue, reduced physical performance, and restless legs syndrome (RLS). Severe anaemia may cause dizziness, dyspnea, palpitation, orthostatism, and syncope, and it decreases the woman's ability to cope with blood loss during delivery. The anaemia may also compromise contractility in the uterine musculature increasing the risk for prolonged labour, caesarean section, and postpartum haemorrhage. Foetal iron deficiency may cause low birthweight and adversely affect foetal and early childhood brain development with long-term deficits. METHODS In this randomised comparative, open-label, single-centre, phase IV trial, 200 pregnant women between 14 and 21 weeks of gestation who have iron deficiency after 4 weeks of standard treatment will be randomised 1:1 to either a single 1000 mg dose of intravenously administered ferric derisomaltose/iron isomaltoside 1000 or a fixed dose of 100 mg oral ferrous fumarate containing 60 mg ascorbic acid. The primary endpoint is to prevent iron deficiency anaemia defined by a low level of haemoglobin throughout the trial. Other endpoints include other haematological indices of iron deficiency and anaemia, clinical outcomes by questionnaires, and collection of adverse events. Explorative endpoints by medical record follow-up include complications up to 7 days after delivery. DISCUSSION This trial will provide evidence on how to prevent iron deficiency anaemia. The trial population represents a clinical reality where pregnant women often have sustained iron deficiency despite an increased oral iron dose. Thus, this evidence can be used to consider the optimal 2nd line of treatment in iron-deficient pregnant women.

[PMID: 32819760 DOI: 10.1016/j.tmrv.2020.07.002] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2020] [Revised: 07/13/2020] [Accepted: 07/16/2020] [Indexed: 02/04/2023]
Abstract
Intravenous iron therapy is increasingly used in patients with iron deficiency anemia, although concerns of hypophosphatemia have been recently raised. The aim of this study was to evaluate different intravenous iron formulations for the risk of hypophosphatemia. Medline, Scopus, Cochrane Central Register of Controlled Trials, Web of Science, Clinicaltrials.gov, and Google Scholar databases were systematically searched to 20 March 2020. All randomized controlled trials reporting the incidence of hypophosphatemia among adult patients treated with any intravenous iron preparation were included. Pool estimates were obtained by applying an arm-based Bayesian network meta-analysis model. Eight randomized controlled trials were included, comprising 5989 patients. Ferric carboxymaltose was associated with significantly higher incidence of hypophosphatemia compared to iron isomaltoside (risk ratio [RR]: 7.90, 95% confidence interval [CI]: 2.10-28.0), iron sucrose (RR: 9.40, 95% CI: 2.30-33.0), iron dextran (RR: 6.60, 95% CI: 1.91-220.0), and ferumoxytol (RR: 24.0, 95% CI: 2.50-220.0). Therefore, ferric carboxymaltose ranked as the worst treatment presenting the highest surface under the cumulative ranking curve (99.1%). No significant differences were estimated for the comparisons among iron isomaltoside, iron sucrose, iron dextran, and ferumoxytol. In conclusion, it is suggested that the occurrence of hypophosphatemia is common after the administration of intravenous ferric carboxymaltose. Further research is needed in large-scale randomized controlled trials to determine the risk of symptomatic and persistent hypophosphatemia as well as to elucidate the exact pathophysiology of the observed association.

Abstract
INTRODUCTION The hypoxia-inducible factor prolyl hydroxylase (HIF-PH) pathway is responsible for regulating the biosynthesis of erythropoietin (EPO) and maintaining iron homeostasis. Investigational drugs that target the HIF-PH pathway are promising alternatives for treating anemia in Chronic Kidney Disease (CKD). AREAS COVERED This review summarizes recent advances focused on the clinical development of HIF-PH inhibitors (HIF-PHIs) as potentially novel therapies in the treatment of anemia in CKD based on publications available on PubMed and restricted Google searches. We provide a comparison between HIF-PHIs regarding their pharmacokinetics, dosing regimens and safety concerns, structure-activity relationships, and alterations in key laboratory parameters observed in animal models and clinical trials. EXPERT OPINION HIF-PHIs may be advantageous in some aspects compared to the conventional erythropoiesis-stimulating agents (ESAs). While ESAs could increase the risk of cardiovascular events due to rapid rises in ESA blood levels, HIF-PHIs have been reported to maintain EPO concentrations at levels that are closer to the normal physiological ranges. Although HIF-PHIs have been demonstrated to be relatively safe and effective in clinical trials, long-term safety data are needed in order to establish whether these therapeutic agents will lead to a major paradigm change in the treatment of anemia of CKD.

[PMID: 32479668 PMCID: PMC7384172 DOI: 10.1111/trf.15837] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2019] [Revised: 02/13/2020] [Accepted: 02/26/2020] [Indexed: 12/20/2022]
Abstract
BACKGROUND Reluctance to use intravenous (IV) iron for the treatment of iron deficiency continues due to a perceived high risk of severe hypersensitivity reactions (HSRs). Additionally, it has been hypothesized that 'dextran-derived' IV iron products (e.g., ferumoxytol [FER] and ferric derisomaltose/iron isomaltoside 1000 [FDI]) have a higher risk of severe HSRs than 'non-dextran-derived' products (e.g., ferric carboxymaltose [FCM] and iron sucrose [IS]). In the present analysis, HSR data from head-to-head randomized controlled trials (RCTs) with IV iron products were evaluated to determine if differences in safety signals are present among these IV iron formulations. STUDY DESIGN AND METHODS Reported serious or moderate-to-severe HSR incidence data from five RCTs (FIRM; FERWON-NEPHRO/-IDA; PHOSPHARE-IDA04/-IDA05) were used to calculate risk differences with 95% confidence intervals (CIs) for FER, FCM, FDI, and IS. The rates and risk differences for these HSRs were compared. RESULTS The analysis included data for 5247 patients: FER (n = 997), FCM (n = 1117), FDI (n = 2133) and IS (n = 1000). Overall rates of serious or moderate to severe HSRs were low (0.2%-1.7%). The risk differences (95% CIs) showed small differences between the IV iron formulations: FER versus FCM, -0.1 (-0.8 to 0.6); FDI versus IS, 0.1 (-0.3 to 0.5); FDI versus FCM, -0.9 (-3.7 to 1.9). CONCLUSION RCT evidence confirms a low risk of serious or moderate to severe HSRs with newer IV iron formulations and no significant differences among existing commercially available products. Thus, RCT data show that the supposed classification of dextran-derived versus non-dextran-derived IV iron products has no clinical relevance.

Abstract
Objectives: It is hypothesized that the risk of hypersensitivity reactions (HSRs) may be lower with ferric carboxymaltose than iron dextran because of its non-dextran carbohydrate moiety. This study compares the risk of HSRs between iron dextran and ferric carboxymaltose.Methods: This was a retrospective pharmacoepidemiological study with a case-population design covering 2008-2017. Global exposure data were estimated using IQVIA™ sales data. Spontaneously reported HSR data were retrieved from the World Health Organization database (VigiBase™) using different search criteria including: the Standardized MedDRA® Query (SMQ) 'Anaphylactic reaction'; type I-IV HSR terms; narrow terms for anaphylactic/anaphylactoid reactions; and cases with a fatal outcome.Results: Total exposure in 100 mg doses was 117.3 million for iron dextran and 84.2 million for ferric carboxymaltose. The relative risk (with 95% confidence interval) for ferric carboxymaltose versus iron dextran was 4.18 (3.88-4.50) for SMQ Anaphylactic reaction; 12.9 (9.90-16.7) for type I-IV HSRs; 1.72 (1.45-2.04) for anaphylactic/anaphylactoid reactions; and 1.92 (1.24-2.99) for death.Conclusion: The risk of spontaneously reported HSRs was consistently higher with ferric carboxy-maltose than with iron dextran over the period 2008-2017. Thus, this study does not support that dextran-free intravenous irons are associated with fewer HSRs than iron dextran.
