Abstract
Patients with inflammatory bowel disease (IBD) are prone to reduced bone mineral density and elevated overall fracture risk. Osteopenia affects up to 40% of patients with IBD (high regional variability). Besides disease activity, IBD specialists must consider possible side effects of medication and the presence of associated diseases and extraintestinal manifestations. Osteopenia and osteoporosis remain frequent problems in patients with IBD and are often underestimated because of widely differing screening and treatment practices. Malnutrition, chronic intestinal inflammation and corticosteroid intake are the major pathophysiological factors contributing to osteoporosis. Patients with IBD are screened for osteoporosis using dual-energy X-ray absorptiometry (DXA), which is recommended for all patients with a prolonged disease course of more than three months, with repeated corticosteroid administration, aged >40 years with a high FRAX risk score or aged <40 years with multiple risk factors. From a therapeutic perspective, besides good disease control, vitamin D supplementation and glucocorticoid sparing, several specific osteological options are available: bisphosphonates, receptor activator of nuclear factor kappa-B ligand (RANKL) inhibitors (denosumab), parathyroid hormone (PTH) analogues and selective estrogen receptor modulators. This review provides an overview of the pathophysiology, diagnosis, prevention and treatment of IBD-associated bone loss.

Abstract
OBJECTIVE To investigate the hepatic effects of high-dose intravenous (IV) iron, including those on liver function and the degree of fibrosis, in a rat model of cirrhosis. METHODS We evenly allocated 25 Sprague-Dawley rats into five groups: normal rats (control group), cirrhotic rats receiving IV normal saline (liver cirrhosis [LC] group), and cirrhotic rats receiving 20, 40, or 80 mg/kg IV ferric carboxymaltose (LC-iron20, LC-iron40, and LC-iron80 group, respectively). Biochemical parameters were compared at 0, 7, 14, 21, and 28 days. The degrees of hepatic fibrosis and iron deposition were evaluated. Inflammatory and oxidative stress markers were also compared. RESULTS There were no significant differences in the 28-day serum alanine aminotransferase levels among the LC-iron20, LC-iron40, and LC-iron80 groups (69 ± 7, 1003 ± 127, 1064 ± 309, 919 ± 346, and 820 ± 195 IU/L in the control, LC, LC-iron20, LC-iron40, and LC-iron80 groups, respectively). Hepatic iron accumulation increased in a dose-dependent manner, but the degree of hepatic fibrosis was comparable among the groups. The inflammatory and oxidative stress marker levels did not differ significantly according to the IV iron dose. CONCLUSIONS Administration of IV iron at various high doses appears safe in our rat model of cirrhosis.

Abstract
Iron-carbohydrate complexes are widely used to treat iron deficiencies. Macrophages play a crucial role in the uptake and fate of these nanomedicines, however, how complexed iron carbohydrates are taken up and metabolized by macrophages is still not fully understood. Using a (phospho-)proteomics approach, we assessed differences in protein expression and phosphorylation in M2 macrophages triggered by iron sucrose (IS). Our results show that IS alters the expression of multiple receptors, indicative of a complex entry mechanism. Besides, IS induced an increase in intracellular ferritin, the loss of M2 polarization, protective mechanisms against ferroptosis, and an autophagic response. These data indicate that macrophages can use IS as a source of iron for its storage and later release, however, the excess of iron can cause oxidative stress, which can be successfully regulated by the cells. When comparing IS with ferric carboxymaltose (FCM) and iron isomaltoside-1000 (IIM), complexes with a higher carbohydrate ligand stability, we observed that FCM and IIM are metabolized at a slower rate, and trigger M2 polarization loss to a lower extent. These results indicate that the surface characteristics of the iron-carbohydrate complexes may influence the cell responses. Our data show that the application of (phospho-)proteomics can lead to a better understanding of metabolic processes, including the uptake, biodegradation and bioavailability of nanomedicines.

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.

Abstract
Introduction. The concept of blood management in relation to the surgical treatment of surgical diseases recommends the correction of iron defi ciency anemia (IDA) at the prehospital stage. However, surgery is often performed for emergency indications, making it necessary to carry out treatment as soon as possible.Aim – to evaluate the possibilities of using delta hemoglobin (Delta-He) to monitor the effectiveness of IDA therapy in neurosurgical patients at the prehospital stage to reduce the time required to prepare patients for hospitalization.Materials and methods. A total of 42 patients were treated with high-dose iron preparations (iron [III] carboxymaltosate and iron [III] hydroxide oligoisomaltosate). During the treatment, the dynamics of the number of reticulocytes and the values of the hemoglobin delta were evaluated. Data are presented as median (IQR).Results. Treatment with high-dose iron preparations led to an increase in Delta-He values starting from days 1–2. Significant changes were recorded by days 3–4 from the start of therapy: from 2.2 (0.3–4.9) pg to 15.5 (13.8–10) pg on day 7. These changes were 2–3 days ahead of the increase in the number of reticulocytes in the corresponding blood samples: the number of reticulocytes significantly increased by days 5–6 from the start of treatment.Conclusion. The use of high-dose preparations of iron [III] carboxymaltosate and iron [III] hydroxide oligoisomaltosate in the form of infusion made it possible to prepare neurosurgical patients for hospitalization within a week. None of the patients required transfusion of erythrocyte-containing components of donated blood at any stage of surgical treatment. The ability to focus on Delta-He values instead of the number of reticulocytes during iron therapy made it possible to shorten the waiting period for the effect of drug exposure by 2–3 days.

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
INTRODUCTION Iron deficiency is a prevalent comorbidity in patients with severe aortic stenosis and may be associated with procedural and clinical outcomes after transcatheter aortic valve implantation (TAVI). In the Intravenous Iron Supplement for Iron Deficiency in Patients with Severe Aortic Stenosis (IIISAS) trial, we aim to examine whether a single administration of ferric derisomaltose can improve physical capacity after TAVI. METHODS AND ANALYSIS This randomised, double-blind, placebo-controlled trial aims to enrol 150 patients with iron deficiency who are scheduled for TAVI due to severe aortic stenosis. The study drug and matching placebo are administered approximately 3 months prior to TAVI, and the patients are followed for 3 months after TAVI. Inclusion criteria are iron deficiency, defined as serum ferritin<100 µg/L or ferritin between 100 and 300 µg/L in combination with a transferrin saturation<20% and written informed consent. Exclusion criteria include haemoglobin<10 g/dL, red blood cell disorders, end-stage kidney failure, intolerance to ferric derisomaltose, and ongoing infections. The primary endpoint is the baseline-adjusted distance walked on a 6 min walk test (6MWT) 3 months after TAVI. Secondary end points include quality of life, New York Heart Association functional class (NYHA functional class), and skeletal muscle strength. ETHICS AND DISSEMINATION Ethical approval was obtained from the Regional Committee for Medical and Health Research of South-Eastern Norway and The Norwegian Medicines Agency. Enrolment has begun, and results are expected in 2022. The results of the IIISAS trial will be disseminated by presentations at international and national conferences and by publications in peer-reviewed journals. TRIAL REGISTRATION NUMBER NCT04206228.

Abstract
Parathyroid gland (PG) injury is the most common complication of thyroidectomy owing to the lack of approaches for surgeons to effectively distinguish PGs from surrounding thyroid glands (TGs) in the operation room. Herein, we report the development of biodegradable iron oxide nanoparticles (IONPs) as a promising contrast agent candidate for intraoperative PG visualization. We elucidated that locally administrated dark-colored IONPs readily diffuse in TGs but cannot infiltrate tissue-dense PGs, yielding a distinguishable contrast enhancement between PGs and TGs by naked eye observation. We performed unbiased and quantitative in vivo screenings to optimize particle size and concentration of IONPs for PG/TG contrast enhancement. Moreover, in vivo applications of IONPs via the local administration route demonstrate no adverse toxicities and can be biodegraded in the thyroid microenvironment within 3 months. To our knowledge, these promising findings provide the first in vivo evidence that IONPs can serve as a safe, biodegradable, and effective contrast agent candidate for improving PG visualization in thyroidectomy.

Abstract
Background Patients with colorectal cancer have a high risk of iron deficiency anaemia (IDA) due to chronic tumour induced blood loss, a reduced dietary iron intake from poor nutrition or gastrointestinal malabsorption. This pilot, double blinded, randomised controlled trial (RCT) examined the effect and feasibility of using preoperative iron isomaltoside for treating iron deficiency anaemia. Methods Forty eligible adults with IDA were randomised to receive either intravenous iron isomaltoside (20 mg.kg-1 up to 1000 mg over 30 minutes) or usual preoperative care (control) three weeks before scheduled colorectal surgery. The primary outcomes were perioperative changes in haemoglobin and ferritin concentrations. Results The recruitment rate was 78% of all eligible referred patients (1.9 patients/month). The haemoglobin and ferritin concentrations were higher in the iron isomaltoside group than the control group over the perioperative period (group*time interaction P = 0.042 and P < 0.001 respectively). Mean haemoglobin change from baseline to before surgery was higher in the iron isomaltoside group (7.8, 95% CI: 3.2 to 12.3 g.l-1) than the control group (1.7, 95% CI: -1.9 to 5.3 g.l-1) [mean difference 6.1, 95% CI: 0.3 to 11.8 g.l-1; P = 0.040]. The ferritin change from baseline to before surgery between groups was large in favour of the iron isomaltoside group (mean difference 296.9, 95% CI: 200.6 to 393.2 μg.l-1; P < 0.001]. There were no differences between groups in packed red blood cell transfusions needed, surgical complications, quality of recovery and days (alive and) at home within 30 days after surgery. Conclusion Iron isomaltoside therapy was safe and had a minimal effect on perioperative changes in haemoglobin concentration. Given the slow recruitment and new evidence emerging during the conduct of this study, conducting a multi-centre RCT based on the current pilot trial protocol is unlikely to be feasible. Trial registration ClinicalTrials.gov NCT03565354.

[PMID: 34394714 PMCID: PMC8358243 DOI: 10.1177/1753495x20932426] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2020] [Accepted: 05/13/2020] [Indexed: 01/01/2023] Open
Abstract
Iron deficiency anaemia is a global health problem, which particularly affects pregnant women. Iron deficiency anaemia during pregnancy is associated with increased maternal and perinatal morbidity and mortality. Maternal iron deficiency may also be associated with neurocognitive deficits in infants. Iron requirements increase during pregnancy and are influenced by hepcidin, the master regulator of iron homeostasis. The enduring global burden of maternal anaemia suggests that currently employed iron supplementation strategies are suboptimal. Recent developments in our understanding of systemic and placental iron homeostasis may improve therapeutic effectiveness by altering the dose and frequency of oral iron. Intravenous iron appears to be a safe treatment to correct maternal anaemia rapidly but research on patient-centred outcomes and cost-effectiveness is needed. Future trials should be adequately powered to assess outcomes relevant to pregnant women.

Abstract
Phosphorus has an essential role in cellular and extracellular metabolism; maintenance of normal phosphorus homeostasis is critical. Phosphorus homeostasis can be affected by diet and certain medications; some intravenous iron formulations can induce renal phosphate excretion and hypophosphatemia, likely through increasing serum concentrations of intact fibroblast growth factor 23. Case studies provide insights into two types of hypophosphatemia: acute symptomatic and chronic hypophosphatemia, while considering the role of pre‐existing conditions and comorbidities, medications, and intravenous iron. This review examines phosphorus homeostasis and hypophosphatemia, with emphasis on effects of iron deficiency and iron replacement using intravenous iron formulations.

Abstract
Iron deficiency and anaemia are global health problems and major causes of morbidity in women. Current definitions of anaemia in women are historic and have been challenged by recent data from observational studies. Menstrual loss, abnormal uterine bleeding and pregnancy put women at risk of developing iron deficiency which can result in severe fatigue, reduced exercise capacity and poor work performance. Iron deficiency and anaemia during pregnancy are associated with adverse maternal and fetal outcomes, including neurocognitive deficits in children born to iron-deficient mothers. Both iron deficiency and anaemia are common in women undergoing surgery but their association with poor outcomes remains uncertain. The enduring burden of iron deficiency and anaemia in women suggests that current strategies for recognition, prevention and treatment are limited in their utility. Improvements in our understanding of iron homeostasis and the development of new iron preparations, which are better absorbed with fewer side-effects, may improve therapeutic effectiveness of oral iron. Intravenous iron is efficacious for correcting anaemia rapidly but high-quality data on patient-centred outcomes and cost-effectiveness are currently lacking. Many recommendations for the treatment of iron deficiency and anaemia in national guidelines are not supported by high-quality evidence. There is a need for robust epidemiological data and well-designed clinical trials. The latter will require collaborative working between researchers and patients to design studies in ways that incorporate patients' perspectives on the research process and target outcomes that matter to them.

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.

Hypophosphataemia after treatment of iron deficiency with intravenous ferric carboxymaltose or iron isomaltoside-a systematic review and meta-analysis. Br J Clin Pharmacol 2020; 87:2256-2273.

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
The most common complication seen in inflammatory bowel disease (IBD) patients is iron deficiency anaemia (IDA). Symptoms such as chronic fatigue can be as debilitating to IBD patients as pathological symptoms of abdominal pain and diarrhoea. Recognising and correcting anaemia may be as important as managing IBD symptoms and improving overall quality of life. Thus, iron replacement should be commenced the moment IDA is identified. Although intravenous iron is now considered standard treatment for IBD patients in Europe, oral iron still appears to be the preferred option. Advantages of oral iron include greater availability, lower costs and ease of applicability. However, its multitude of side effects, impact on the microbiome and further exacerbating IBD activity can have consequences on patient compliance. The newer oral iron formulations show promising safety and efficacy data with a good side effect profile. Intravenous iron formulations bypass the gastrointestinal tract absorption thereby leading to less side effects. Multiple studies have shown its superiority compared to oral formulations although its risk for hypersensitivity reactions continue to lead to clinician hesitancy in prescribing this formulation. This article provides an updated review on diagnosis and management of IDA in IBD patients, discussing the newer oral and intravenous formulations.

Abstract
Perioperative anaemia increases postoperative morbidity and mortality, and iron deficiency is anaemia’s most common cause in surgical patients. Preoperative intravenous iron increases postoperative haemoglobin; however, data regarding intraoperative intravenous iron’s effectiveness are inadequate. This study examined intraoperative intravenous iron’s effects on postoperative haemoglobin levels in adults. Fifty-seven healthy subjects (aged 19–40 years) scheduled for bimaxillary orthognathic surgery were assigned randomly to the iron (n = 28) or control (n = 29) groups. The iron group received intravenous ferric derisomaltose (1,000 mg) after anaesthetic induction. The control group received an identical volume of intravenous normal saline. The primary outcome was postoperative haemoglobin level. Secondary outcomes included other postoperative haematologic and iron parameters. Laboratory data were obtained preoperatively and at 1 day, 2 weeks, and 4 weeks postoperatively. Haemoglobin was higher in the iron group 2 weeks postoperatively (12.9 g/dL vs. 12.2 g/dL), but the between-group difference was not significant after adjustment for multiple testing. However, the reticulocyte production index was significantly higher in the iron group 2 weeks postoperatively. Intraoperative intravenous iron maintains postoperative haemoglobin values in patients undergoing bimaxillary orthognathic surgery by increasing haematopoietic function and iron bioavailability and therefore appears to be a useful strategy for blood management.

Abstract
Background Anaemia is common in haemodialysis (HD) patients and associated with significant morbidity and mortality. Intravenous (IV) iron combined with erythropoiesis-stimulating agents (ESA) is the mainstay treatment of anaemia in these patients. The comparative efficacy and risk of adverse events with IV iron preparations have been assessed in only a few trials. Methods This was a retrospective observational study in 2 centres designed to compare the safety and efficacy of iron sucrose (IS-Venofer®) versus iron isomaltoside (IIM-Diafer®) in haemodialysis patients. The study included patients currently on dialysis and receiving Venofer who were switched to Diafer® and monitored for at least 12 months for each iron preparation. Results A total of 190 patients were included and had a mean age of 65.8 years (SD ± 15.5). Non-inferiority was confirmed with no change in mean haemoglobin per mg of iron administered over a 12-month period. In total there were 41,295 prescriptions of iron isomaltoside and 14,685 of iron sucrose with no difference in the number of reported adverse events during the study period (7 each, none were severe). There was a statistically significant effect on Hb over time after conversion, including adjustment for multiple comparisons. There were significant improvements in ferritin over time, which remained at 6 months (P < 0.01). The weekly iron dose was similar after adjustment (P = 0.02). The EPO dose did not differ significantly after month 0 in patients switched to IIM. Conclusions This study demonstrates the comparative safety and efficacy of iron isomaltoside versus iron sucrose, with similar dosing schedules in dialysis patients. Iron isomaltoside is non-inferior to iron sucrose in maintaining Hb in patients on regular haemodialysis/haemodiafiltration with no difference in the number of reported adverse events.

Abstract
PURPOSE To evaluate the efficacy and safety for mother and child of using intravenous iron isomaltoside (IV-IIM) during pregnancy. METHODS Using an appointment register, we retrospectively identified all pregnant women who received a single dose of 1000 or 1500 mg IV-IIM in the maternity ward of Falu Hospital and subsequently gave birth between August 6, 2013 and July 31, 2018. Women who received IV-IIM (case group) were individually matched with pregnant women who did not receive IV-IIM (control group) by delivery date, maternal age (± 2 years), and parity. Adverse drug reactions (ADRs), demographic characteristics, hemoglobin and s-ferritin counts, pregnancy and delivery complications, and infant data (APGAR score, pH at umbilical artery, birthweight, birth length, intrauterine growth restriction and neonatal ward admission). Data were obtained from electronic patient charts. SPSS was used for descriptive statistics. RESULTS During the 5-year period, 213 women each received a single administration of IV-IIM. Ten (4.7%) ADRs occurred during IV-IIM administration. All ADRs were mild hypersensitivity reactions, abated spontaneously within a few minutes, and did not recur on rechallenge. No association between IIM dose and ADR frequency was noted. Maternal and fetal outcomes, including hemoglobin counts at delivery and postpartum, were similar in the case and control groups. CONCLUSION These results support the convenience, safety, and efficacy of a single high-dose (up to 1500 mg) infusion of IV-IIM for iron deficiency or iron deficiency anemia during pregnancy.

Abstract
Erythropoietin and iron have individually shown beneficial effects on early-phase liver regeneration following partial hepatectomy (PHx); however, there are limited data on the combined effect on late-phase liver regeneration after PHx. Here we examined combined effects of recombinant human erythropoietin (rhEPO, 3,000 IU/kg) and iron isomaltoside (IIM, 40 mg/kg) on late-phase liver regeneration following PHx and investigated the possible underlying mechanism. Rats administrated with rhEPO showed significantly higher liver mass restoration, interleukin-6 (IL-6, a hepatocyte mitogen) levels, and Ki-67-positive hepatocytes on day 7 after PHx than saline-treated controls. These beneficial effects were further enhanced on days 7 and 14 by co-treatment with IIM. This combination also significantly improved liver function indices, such as increased albumin production and decreased bilirubin levels, but did not alter serum levels of toxic parameters, such as aspartate transaminase and alanine transaminase. This study demonstrates that the combination of rhEPO and IIM synergistically improves late-phase liver regeneration and function after PHx, probably by promoting IL-6-mediated hepatocyte proliferation without adverse effects. Thus, this combination treatment can be a potential therapeutic strategy for patients undergoing resection for hepatic malignancies.

NANOMEDICINE-NANOTECHNOLOGY BIOLOGY AND MEDICINE 2020; 26:102178. [PMID: 32145382 DOI: 10.1016/j.nano.2020.102178] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/24/2019] [Revised: 01/06/2020] [Accepted: 02/19/2020] [Indexed: 02/06/2023]
Abstract
Iron deficiency is an important subclinical disease affecting over one billion people worldwide. A growing body of clinical records supports the use of intravenous iron-carbohydrate complexes for patients where iron replenishment is necessary and oral iron supplements are either ineffective or cannot be tolerated by the gastrointestinal tract. A critical characteristic of iron-carbohydrate drugs is the complexity of their core-shell structure, which has led to differences in the efficacy and safety of various iron formulations. This review describes parameters influencing the safety and effectiveness of iron-carbohydrate complexes during production, storage, handling, and clinical application. We summarized the physicochemical and biological assessments of commercially available iron carbohydrate nanomedicines to provide an overview of publicly available data. Further, we reviewed studies that described how subtle differences in the manufacturing process of iron-carbohydrate complexes can impact on the physicochemical, biological, and clinical outcomes of original product versus their intended copies or so-called iron "similar" products.

Abstract
Safety of parenteral iron therapy is critical and has been demonstrated in several studies, but concerns persist on safety. We performed a retrospective single-center study investigating the safety and efficacy of parenteral iron administration using 2 iron preparations-Monofer and Cosmofer (Pharmacosmos A/S, Holbaek, Denmark)-in patients with chronic kidney disease (CKD), on peritoneal dialysis (PD) and non-dialysis. A database of CKD patients receiving intravenous (IV) iron was analyzed. Side effects were recorded during infusion, post-infusion, and after 48 hours. In a population of CKD patients (non-dialysis and PD), IV iron is safe with few major adverse effects for these 2 IV iron preparations studied with similar dosing schedules. These data provide reassurance on the relative short-term safety of IV iron preparations regarding acute infusion-related hypersensitivity reactions.

Abstract
Iron deficiency anemia (IDA) is prevalent, and intravenous iron, especially if given in a single dose, may result in better adherence compared with oral iron. The present trial (FERWON‐IDA) is part of the FERWON program with iron isomaltoside 1000/ferric derisomaltose (IIM), evaluating safety and efficacy of high dose IIM in IDA patients of mixed etiologies. This was a randomized, open‐label, comparative, multi‐center trial conducted in the USA. The IDA patients were randomized 2:1 to a single dose of 1000 mg IIM, or iron sucrose (IS) administered as 200 mg intravenous injections, up to five times. The co‐primary endpoints were adjudicated serious or severe hypersensitivity reactions, and change in hemoglobin from baseline to week eight. A total of 1512 patients were enrolled. The frequency of patients with serious or severe hypersensitivity reactions was 0.3% (95% confidence interval: 0.06;0.88) vs 0.4% (0.05;1.45) in the IIM and IS group, respectively. The co‐primary safety objective was met, and no risk difference was observed between groups. The co‐primary efficacy endpoint of non‐inferiority in hemoglobin change was met, and IIM led to a significantly more rapid hematological response in the first two weeks. The frequency of cardiovascular events was 0.8% and 1.2% in the IIM and IS group, respectively (P = .570). The frequency of hypophosphatemia was low in both groups. Iron isomaltoside administered as 1000 mg resulted in a more rapid and more pronounced hematological response, compared with IS, which required multiple visits. The safety profile was similar with a low frequency of hypersensitivity reactions and cardiovascular events.

Abstract
BACKGROUND Iron deficiency and iron deficiency anaemia are common complications in inflammatory bowel disease (IBD). In patients with moderate-to-severe anaemia, oral iron intolerance or ineffectiveness of oral iron, ferric carboxymaltose and iron isomaltoside are widely used. Hypophosphatemia is a side effect of both preparations. AIMS To investigate the occurrence of hypophosphatemia in IBD patients with iron deficiency/iron deficiency anaemia treated with high-dose intravenous iron. METHODS A prospective observational study of adult IBD patients with iron deficiency/iron deficiency anaemia was conducted at two study sites where patients received 1000 mg of ferric carboxymaltose or iron isomaltoside. At baseline, weeks 2 and 6, blood and faecal samples were collected. The primary endpoint was to determine the incidence of moderate-to-severe hypophosphatemia. Secondary endpoints included the total incidence of hypophosphatemia, possible risk factors for hypophosphatemia, and response to single-dose intravenous iron. RESULTS One hundred and thirty patients were included. In the per-protocol set, 52 patients received ferric carboxymaltose and 54 patients received iron isomaltoside. Ferric carboxymaltose treatment had a significantly higher incidence of moderate-to-severe hypophosphatemia compared with iron isomaltoside at week 2 (56.9% vs 5.7%, P < 0.001) and a higher incidence at week 6 (13.7% vs 1.9%, P = 0.054).The overall incidence of hypophosphatemia was significantly higher with ferric carboxymaltose compared with iron isomaltoside treatment at weeks 2 (72.5% vs 11.3%, P < 0.001) and 6 (21.6% vs 3.7%, P = 0.013). CONCLUSIONS In IBD patients with iron deficiency/iron deficiency anaemia, ferric carboxymaltose was associated with higher incidence, severity and persistence of hypophosphatemia compared with iron isomaltoside. The presence of moderate-to-severe hypophosphatemia beyond 6 weeks is a clinical concern that requires further investigation.

Abstract
Nanotechnology, as an interdisciplinary science, combines engineering, physics, material sciences, and chemistry with the biomedicine knowhow, trying the management of a wide range of diseases. Nanoparticle-based devices holding tumor imaging, targeting and therapy capabilities are formerly under study. Since conventional hematological therapies are sometimes defined by reduced selectivity, low therapeutic efficacy and many side effects, in this review we discuss the potential advantages of the NPs' use in alternative/combined strategies. In the introduction the basic notion of nanomedicine and nanoparticles' classification are described, while in the main text nanodiagnostics, nanotherapeutics and theranostics solutions coming out from the use of a wide-ranging NPs availability are listed and discussed.

Abstract
OBJECTIVES The efficacy of oral iron in treating iron deficiency anemia (IDA) can be limited by poor gastrointestinal (GI) absorption and adverse GI symptoms; intravenous (IV) iron is a well-established alternative. The present study compared the efficacy of two IV iron formulations in patients with IDA: iron isomaltoside (IIM) and ferric carboxymaltose (FCM). METHODS A systematic literature review (SLR) was conducted to identify randomized controlled trials (RCTs) of IIM and FCM in patients with IDA. An adjusted indirect treatment comparison (ITC) of IIM and FCM was then conducted to evaluate differences in change from baseline hemoglobin and the proportion of patients achieving a clinically-relevant response. RESULTS The SLR identified no completed RCTs of IIM versus FCM, 5 RCTs of IIM (4 versus oral iron and 1 versus iron sucrose), and 14 RCTs of FCM (11 versus oral iron and 3 versus iron sucrose). In an ITC via iron sucrose, IIM resulted in a significantly larger increase from baseline hemoglobin with a mean difference of +0.249 g/dL with IIM relative to FCM, but there was no significant difference in the proportion of patients with a clinically-relevant response. CONCLUSIONS IIM resulted in a larger increase from baseline hemoglobin than FCM in patients with IDA, but with no difference in the proportion of patients responding. Studies comparing IIM and FCM directly would be needed to confirm these findings.

Abstract
Anemia is a major health condition associated with chronic kidney disease (CKD). A key underlying cause of this disorder is iron deficiency. Although intravenous iron treatment can be beneficial in correcting CKD-associated anemia, surplus iron can be detrimental and cause complications. Excessive generation of reactive oxygen species (ROS), particularly by mitochondria, leads to tissue oxidation and damage to DNA, proteins, and lipids. Oxidative stress increase in CKD has been further implicated in the pathogenesis of vascular calcification. Iron supplementation leads to the availability of excess free iron that is toxic and generates ROS that is linked, in turn, to inflammation, endothelial dysfunction, and cardiovascular disease. Histidine is indispensable to uremic patients because of the tendency toward negative plasma histidine levels. Histidine-deficient diets predispose healthy subjects to anemia and accentuate anemia in chronic uremic patients. Histidine is essential in globin synthesis and erythropoiesis and has also been implicated in the enhancement of iron absorption from human diets. Studies have found that L-histidine exhibits antioxidant capabilities, such as scavenging free radicals and chelating divalent metal ions, hence the advocacy for its use in improving oxidative stress in CKD. The current review advances and discusses evidence for iron-induced toxicity in CKD and the mechanisms by which histidine exerts cytoprotective functions.

Abstract
Absolute or functional iron deficiency is the most prevalent cause of anaemia in surgical patients, and its correction is a fundamental strategy within "Patient Blood Management" programmes. Offering perioperative oral iron for treating iron deficiency anaemia is still recommended, but intravenous iron has been demonstrated to be superior in most cases. However, the long-standing prejudice against intravenous iron administration, which is thought to induce anaphylaxis, hypotension and shock, still persists. With currently available intravenous iron formulations, minor infusion reactions are not common. These self-limited reactions are due to labile iron and not hypersensitivity. Aggressively treating infusion reactions with H1-antihistamines or vasopressors should be avoided. Self-limited hypotension during intravenous iron infusion could be considered to be due to hypersensitivity or vascular reaction to labile iron. Acute hypersensitivity reactions to current intravenous iron formulation are believed to be caused by complement activation-related pseudo-allergy. However, though exceedingly rare (<1:250,000 administrations), they should not be ignored, and intravenous iron should be administered only at facilities where staff is trained to evaluate and manage these reactions. As preventive measures, prior to the infusion, staff should inform all patients about infusion reactions and identify those patients with increased risk of hypersensitivity or contraindications for intravenous iron. Infusion should be started at a low rate for a few minutes. In the event of a reaction, the very first intervention should be the immediate cessation of the infusion, followed by evaluation of severity and treatment. An algorithm to scale the intensity of treatment to the clinical picture and/or response to therapy is presented.

Abstract
AIMS Iron deficiency anaemia (IDA) is common in patients with inflammatory bowel disease (IBD), who are often treated with intravenous iron. This observational study aimed to investigate the effectiveness and safety of iron isomaltoside in routine practical care of IDA in IBD patients. METHODS The study included 197 IBD patients designated for treatment with iron isomaltoside. Treatment was administered according to routine practice. Data were recorded at baseline and after approximately 4, 8, and 16 weeks. Efficacy data included haemoglobin (Hb) levels and haematinics, while safety data included adverse drug reactions and safety laboratory variables. RESULTS Patients received a mean (range) cumulative dose of 1304 (100-3500) mg iron isomaltoside. Hb increased from 10.7(±1.6) g/dL at baseline to 13.1(±1.5) g/dL at the final visit. In addition, serum iron, ferritin and transferrin saturation increased and soluble transferrin receptor decreased. Calprotectin decreased, as did IBD symptom scores, Harvey-Bradshaw Index (Crohn's disease) and partial Mayo score (Ulcerative colitis). About 8% of patients reported transient adverse reactions, most commonly skin reactions, nausea and vomiting, and 2% SAEs, most frequently tachycardia. CONCLUSION Iron isomaltoside was demonstrated to be effective and had a good safety profile in IBD patients in everyday clinical practice in Germany.

Abstract
Iron deficiency or iron deficiency anemia (IDA) are some of the most common systemic complications of inflammatory bowel diseases (IBD). Symptoms such as fatigue, reduced ability to concentrate and reduced exercise tolerance can mimic common symptoms of IBD and can therefore easily be overseen. Furthermore, clinicians tend to see mild to moderate anemia as an inevitable accompaniment of IBD that is sufficiently explained by the underlying disease and does not require further workup. But in contrast to these clinical routines, current guidelines recommend that any degree of anemia in patients with IBD should be further evaluated and treated. Multiple studies have shown that anemia is a main factor for decreased quality of life (QoL) in patients with IBD. Correction of anemia, however, can significantly improve the QoL of patients with IBD. It is therefore recommended that every patient with IBD is regularly screened for iron deficiency and anemia. If detected, appropriate workup and treatment should be initiated. Over the last years, a number of new diagnostic tools and treatment options have been developed. Multiple studies have demonstrated the safety of newer formulations of intravenous iron in patients with IBD and have compared oral and intravenous iron in various situations. Treatment recommendations have changed and new evidence-based guidelines were developed. However, to date these guidelines are still not widely implemented in clinical practice. The aim of this review is to draw attention to the need for treatment for every level of anemia in patients with IBD and to provide some practical guidance for screening, diagnostics, treatment and follow up of IDA in patients with IBD following current international guidelines.

Abstract
PURPOSE OF REVIEW Iron deficiency anaemia (IDA) is common and associated with fatigue, reduced quality of life and poorer clinical outcomes. Treatment with oral iron is often inadequate and international guidelines recommend intravenous (i.v.) iron as the preferred option for the treatment of IDA in certain clinical situations. In this review, we assess the safety of using i.v. iron with a particular focus on patients with chronic kidney disease. RECENT FINDINGS Recent publications have raised safety concerns regarding the incidence of serious reactions accompanying i.v. infusion, as well as the subsequent risk of infections and cardiovascular events. Methodological flaws influence the interpretation of these data that lack evidence from the use of modern irons. The latter have been investigated in several randomized control trials. SUMMARY There is a need for better understanding and definition of the nature of i.v. iron reactions, as many are nonserious infusion reactions rather than true anaphylaxis. Retrospective identification of anaphylaxis is difficult and we suggest the importance of reanalysing data using fatalities or standardized terms as outcome measures. With the exception of high molecular weight iron dextran, serious or life-threatening reactions are rare with the use of i.v. irons, and they can be used safely for the treatment of IDA.

AIMS Intravenous (IV) iron infusions have been associated with hypophosphataemia (HP) and hypersensitivity reactions (HSRs). No studies have compared the side effects of ferric carboxymaltose (FCM) with those of isomaltoside 1000 (ISM). This study aimed to describe the occurrence of HP and HSRs following the administration of either FCM or ISM. METHODS Data on 231 outpatients treated with IV iron infusions, between November 2011 and April 2014, were collected. During that period, the department made a switch from FCM to ISM and then back to FCM. Of the 231 patients, 39 received both FCM and ISM during the period. The prevalences of HP and HSRs were compared between the two drugs. RESULTS We found more HP events when FCM was given (64 vs. 9; P < 0.01). In contrast, more patients had mild HSRs when ISM was given (2.5% vs. 10.7%; P < 0.01). A comparison of the two drugs in the subpopulation who received both drug types (n = 39) revealed a difference in phosphate decrease (P < 0.01), with the most marked decrease occurring with FCM. Nine patients who had HSRs were exposed to both drugs. No potential HSR crossover between the two drugs was found. CONCLUSION We found a higher risk of HP with FCM administration when compared to ISM administration. Conversely, we found a higher risk of mild HSRs with ISM administration when compared to FCM administration. The impacts of the two types of side effects should be considered when choosing an IV iron drug.

Abstract
Iron-deficiency anemia is the most common hematologic problem in the world. Although oral iron is often viewed as front-line therapy, extensive published evidence has accumulated that IV iron is superior, in both efficacy and safety, to oral iron in many clinical situations and should be introduced much sooner in the treatment paradigm of iron-deficient patients. In this chapter, we will review the formulations of IV iron that allow total complete replacement doses in 1 or 2 sessions including practical tips for administration. We realize safety concerns abound and therefore will analyze evidence based overstated concerns regarding serious adverse events highlighting unnecessary interventions for minor, self-limiting infusion reactions, which infrequently occur with intravenous iron administration. Recent data for the use of IV iron in a variety of clinic situations will be reviewed including women with heavy uterine bleeding, pregnancy, bariatric surgery, inflammatory bowel disease, and restless legs syndrome. Briefly discussed is the new frontier of IV iron's use in the prevention of acute (high altitude) mountain sickness. It is clear that in many clinical situations IV iron is a new and improved standard of care offering advantages over oral iron in efficacy, toxicity, and convenience to patients and health care providers.
