Abstract
BACKGROUND Diagnosing iron deficiency is challenging in the presence of systemic inflammation. AIM To investigate the relationship between plasma C-reactive protein (CRP), serum ferritin (SF) and transferrin saturation (TS), with the objective of establishing a straightforward ratio applicable in the presence of inflammatory syndrome. DESIGN Test prospective cohort and validation retrospective cohort. METHODS A prospective cohort of inpatients (n = 140) assessed the correlation between CRP and SF/TS levels. The diagnostic performance of a determined ratio was evaluated for identifying iron deficiency (ID) using different definitions and in the presence of inflammation and/or chronic heart and/or kidney failure. A large validation cohort (n = 795) further assessed the predictive power of this ratio. RESULTS In a training cohort (median age 76 years [57-84]), a linear relation was observed between SF (µg/l) and CRP (mg/l), unlike with TS. The SF/CRP ratio accurately predicted ID, with receiver operating characteristic-area under the curve (ROC-AUC) values ranging from 0.85 to 0.92 for different ID definitions. A threshold of ≤6 demonstrated the highest Youden index (0.61). In the validation cohort (age 72 years [57-84]), the SF/CRP ratio exhibited an ROC-AUC of 0.88 [95% CI: 0.85-0.90], with an odds ratio of 37.9 [95% CI: 20.3-68.9] for the threshold of ≤6. CONCLUSION In this study, we demonstrated that the SF/CRP ratio, with a threshold of ≤6, is a simple and effective biomarker for ID, even in the presence of systemic inflammation or comorbidities. This ratio could potentially replace the complex set of criteria currently recommended by learned societies.

Abstract
INTRODUCTION Anemia and transfusion of blood products are risk factors associated with poor patient outcomes across all elective surgeries. Patient blood management (PBM) is a patient-centered approach to optimize patient's endogenous red cell mass, to minimize blood loss in patients undergoing surgery, and to harness and optimize patient-specific physiological tolerance to anemia. This study aimed to assess (1) the impact of PBM on blood product usage in cardiovascular surgeries in a state hospital setting, (2) cost-effectiveness of PBM with a model based on transfusion of red blood cells (RBCs) in cardiovascular surgeries, and (3) the budget impact of PBM implementation based on transfusion of RBCs. METHODS Cost-effectiveness and budget impact models, based on the numbers of avoided transfusions and avoided complications after implementation of the PBM program, were compared between pre- and post-PBM periods at the cardiovascular surgery department of Ankara Bilkent City Hospital between February 11, 2019 and July 24, 2022. The probabilities of transfusions and complications with and without PBM were taken from recent meta-analyses. Data from the Ankara Bilkent City Hospital transfusion center informed the pre- and post-PBM calculations. Costs were calculated from the Social Security Institution's perspective. RESULTS There was a 21% decrease in the use of RBCs and a 23.7% decrease in use of all blood products after the implementation of PBM. The number of RBC packs per patient reduced by 0.88 packs (21%). The cost saving from reduction of RBC transfusions per patient was 518.68 Turkish lira (TRY) and for the hospital it was 1,635,948 TRY. Fewer complications and lower costs in favor of the post-PBM arm were demonstrated in the cost-effectiveness analysis. On the basis of the budget impact model, in 20 months, the hospital's cardiovascular surgery department saved 6,596,934 TRY (€342,302). CONCLUSION This hospital-based study demonstrated that PBM is a budget-saving and cost-effective option in Turkey.

Abstract
The association of thrombocytosis with iron deficiency anemia (IDA) is well-recognized, but data describing the rate, predictors, and risk of thrombotic complications associated with IDA-related thrombocytosis are limited. We queried an institutional patient data repository containing comprehensive chart data for over 6 million patients to identify IDA patients with and without thrombocytosis and thrombotic events over a 40-year time period (1979 to 2019). Demographics, hematological parameters, thrombosis history, and other medical history were collected. Fidelity of query data was assessed via detailed manual chart review of 700 patients, including confirmation of ferritin and hematologic parameters in addition to temporal and clinical association of thrombocytosis. Our queries identified 36 327 cases of IDA of which 15 022 had thrombocytosis. Following assessment for data integrity, we observed a thrombocytosis rate of 32.6% in patients with IDA. The rate of thrombosis was calculated to be 7.8% in patients with IDA and 15.8% in patients with IDA and thrombocytosis. Platelet mass index at time of peak thrombocytosis was significantly higher than at baseline and was strongly negatively correlated with hemoglobin at peak thrombocytosis. A multivariable model demonstrated a significant predictive relationship between decreasing hemoglobin and increasing platelet count at peak thrombocytosis. In conclusion, we observed reactive thrombocytosis in one-third of IDA patients, and a 2-fold thrombosis risk in patients with IDA and thrombocytosis compared with patients with IDA alone. Given the global burden of untreated and undertreated IDA, adequate IDA treatment may reduce thrombotic complications and associated morbidity and mortality.

Abstract
INTRODUCTION This study aimed to quantify the potential epidemiological and health economic benefits of implementing preoperative anaemia measures (PAMs) in clinical practice in the German healthcare system. METHODS An evidence-based health economic model was developed to assess the possible impact of implementing PAMs, the first pillar of patient blood management (PBM), in a German population. The analysis of two risk factors-iron-deficiency anaemia (IDA) and receipt of a red blood cell concentrate (RBC) transfusion during elective surgery-allowed the estimation of relative risks (RRs), average cost per patient, average length of hospital stay, and avoided hospital deaths after the implementation of PAMs. RESULTS A total of 4,591,060 patients who had undergone elective surgery during 2015 were identified, of which 29,170 (0.64%) were diagnosed with preoperative IDA. These patients had an increased RR of receiving a RBC transfusion during surgery (RR 5.031; 95% confidence interval [CI] 4.928, 5.136) and increased mortality risk (RR 3.630; 95% CI 3.401, 3.874) versus patients without IDA. Patients who received a RBC transfusion during surgery had a 24.6-times higher risk of death than those who did not (RR 24.593; 95% CI 24.121, 25.075). Average cost of treatment was €7883 in patients with IDA, €21,744 in patients with IDA and RBC transfusion, and €4560 in patients without risk factors. The model identified 29,714 patients (0.65%) who had received a RBC transfusion and who potentially had IDA but remained undiagnosed before surgery. Hypothetical implementation of PAMs would have resulted in an estimated annual net hospital direct cost saving of €1029 million (1.58%) of total hospital direct costs of the German healthcare system and 3036 hospital deaths (0.07%) avoided. CONCLUSIONS This model estimated the impact of implementing PAMs for patients with IDA undergoing elective surgery. A significant number of deaths, costly treatments, and hospital days could have been avoided by the introduction of PAMs in routine clinical practice in Germany.

Treatment of iron deficiency in patients with chronic kidney disease: A prospective observational study of iron isomaltoside (NIMO Scandinavia)
. Clin Nephrol 2019; 91:246-253. [PMID: 30614439 PMCID: PMC6434427 DOI: 10.5414/cn109474] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/20/2019] [Indexed: 11/18/2022] Open
Abstract
Aims: Iron deficiency is common in patients with chronic kidney disease (CKD). Appropriate iron substitution is critical and intravenous iron is an established therapy for these patients. The objective of this study was to assess treatment routine, effectiveness, and safety of iron isomaltoside (Monofer®, Pharmacosmos A/S, Holbaek, Denmark) in CKD patients in clinical practice. Materials and methods: This was a prospective observational study conducted in predialysis CKD patients treated with iron isomaltoside according to the product label and to routine clinical care. Results: The study included 108 patients with predialysis CKD: 22 were in stage 2 – 3, 41 in stage 4, and 45 in stage 5. The mean (standard deviation) age was 67 (15) years, and 55% of patients were male. The majority of patients (65%) received one iron isomaltoside treatment. In patients with a baseline Hb < 10 g/dL, the mean dose of iron isomaltoside in the study was lower than the estimated total iron requirement (567 mg versus 921 mg). A treatment response of Hb ≥ 1 g/dL was achieved in 16/28 (57%) of patients, and the mean post-treatment Hb level was 10.5 g/dL. The probability of retreatment did not correlate with dose, but no dose administered was > 1,000 mg. There were no serious adverse drug reactions. One nonserious adverse drug reaction – injection site discoloration – was reported, and the patient had an uneventful recovery. Conclusion: Iron isomaltoside shows a good effectiveness and safety profile in predialysis CKD patients. However, some patients did not receive adequate iron doses to allow for optimal correction of their iron deficiency anemia.

Abstract
Background Iron deficiency is frequent in haemodialysis (HD) patients with chronic kidney disease (CKD), and intravenous iron is an established therapy for these patients. This study assessed treatment routine, effectiveness, and safety of iron isomaltoside (IIM) 5% (Diafer®) in a HD cohort. Methods This prospective observational study included 198 HD patients converted from iron sucrose (IS) and treated with IIM according to product label and clinical routine. Data for IIM were compared to historic data for IS in 3-month intervals. The primary endpoint was to show non-inferiority for IIM versus IS in haemoglobin (Hb) maintenance. Results Most patients (> 60%) followed a fixed low-dose iron treatment protocol. Three minutes were required for preparation and administration of IIM. Erythropoiesis-stimulating agent (ESA) was used in > 80% of patients during both IIM and IS phases. The maintenance of Hb was similar with both iron drugs; the mean Hb level was 11 g/dL, and the mean change of 0.3 g/dL (95% confidence interval: 0.1, 0.5) for IIM 0–3 months compared to IS demonstrated non-inferiority. Nine adverse drug reactions were reported in 2% of patients administered IIM. All patients had uneventful recoveries. The frequency of metallic taste was higher with IS compared to IIM (34% versus 0.5%, p < 0.0001). Conclusions IIM is effective and well tolerated by CKD patients on HD. IIM was non-inferior to IS in maintenance of Hb, and had similar ESA requirements. The fast-push injection of IIM may enable logistical benefits in clinical practice, and the low frequency of metallic taste contributes to patient convenience.

Abstract
BACKGROUND An analytic-decision model was built to estimate the cost-effectiveness of using ferric carboxymaltose for pre-operative haemoglobin optimisation in patients with iron deficiency anaemia undergoing primary knee arthroplasty. MATERIALS AND METHODS We simulated 20,000 patients who were randomly assigned to the haemoglobin optimisation arm or the non-optimisation control arm in a strict 1:1 ratio. The main outcomes were cost per patient transfusion avoided and red blood cell units spared. The analyses were performed from the hospital perspective with length of stay as the time horizon. RESULTS In the reference case scenario, pre-operative haemoglobin optimisation led to fewer patients being exposed to allogeneic red blood cell transfusion (2,212 vs 6,595 out of 10,000 patients) and a relevant decrease in the number of red blood cell units transfused (4.342 vs 13.336). The costs of avoiding one patient transfusion and sparing one red blood cell unit were € 831 and € 405, respectively. Increased costs in the optimisation arm were mostly associated with the outpatient day hospital visit (54%) and ferric carboxymaltose treatment (40%). DISCUSSION In primary knee arthroplasty, pre-operative haemoglobin optimisation with intravenous ferric carboxymaltose is less expensive than other reported patient blood management modalities and must be considered in patients with iron deficiency anaemia.

Abstract
Background Perioperative administration of ferric carboxymaltose (FCM) was previously shown to reduce both the need for transfusions and the hospital length of stay in patients with preoperative iron deficiency anemia (IDA). In this study, we estimated the economic consequences of perioperative administration using FCM vs usual care in patients with IDA from the perspective of a German hospital using decision-analytic modeling. Materials and methods The model was populated with clinical inputs (transfusion rates, blood units transfused, hospital length of stay) from a previously reported randomized trial comparing FCM vs usual care for managing IDA patients undergoing elective abdominal surgery. We applied a hospital perspective to all costs, excluding surgery-related costs in both treatment arms. One-way sensitivity analyses were undertaken to evaluate key drivers of cost analysis. Results The average costs per case treated using FCM compared to usual care were €2,461 and €3,246, respectively, for resource expenses paid by hospital per case. This would suggest potential savings achieved with preoperative intravenous iron treatment per patient of €786 per case. A sensitivity analysis varying the key input parameters indicated the cost analysis is most sensitive to changes in the length of stay and the cost of hospitalization per day. Conclusion Perioperative administration of FCM results in cost savings to hospitals based on reduced blood transfusions and length of stay following elective abdominal surgery.

Abstract
INTRODUCTION Erythropoietin (EPO) is a commonly used option in the treatment of chemotherapy-induced anaemia (CIA). However, ∼30-50% of patients fail to achieve an adequate response after initial treatment. Prior studies have demonstrated that intravenous iron might synergistically improve therapeutic response to EPO treatment in this patient population. METHODS AND ANALYSIS We will perform this multicentre, randomised, open-label, parallel-group, active controlled non-inferiority study to compare the two combination therapies of EPO plus intravenous iron regimen versus doubling the dose of EPO in patients with CIA who have an inadequate response to initial EPO treatment at a routine dose. A total of 603 patients with an increase in haemoglobin (Hb) <1 g/dL will be enrolled and randomised to one of the three study treatment groups at a 1:1:1 ratio Group 1: EPO treatment at the original dose plus intravenous iron dextran 200 mg every 3 weeks (Q3W) for 15 weeks; Group 2: EPO treatment at the original dose plus intravenous iron dextran 100 mg, twice a week for 5 weeks; Group 3: the control group, doubling the EPO dose without preplanned iron supplementation. The primary outcome measure to compare is the Hb response rate at week 15 and the secondary end points involve therapeutic blood transfusions. Time-to-progression, adverse events and quality of life will also be evaluated. ETHICS AND DISSEMINATION All participants will provide informed consent; the study protocol has been approved by the independent ethics committee of Shanghai East Hospital. This study would clearly demonstrate the potential benefit of combining epoetin treatment with intravenous iron supplementation. Findings will be shared with participating hospitals, policymakers and the academic community to promote the clinical management of CIA in China. TRIAL REGISTRATION NUMBER NCT02731378.

Abstract
Anemia is a frequent complication in cancer patients, both at diagnosis and during treatment, with a multifactorial etiology in most cases. Iron deficiency is among the most common causes of anemia in this setting and can develop in nearly half of patients with solid tumors and hematologic malignancies. Surprisingly, this fact is usually neglected by the attending physician in a way that proper and prompt investigation of the iron status is either not performed or postponed. In cancer patients, functional iron deficiency is the predominant mechanism, in which iron availability is reduced due to disease or the therapy-related inflammatory process. Hence, serum ferritin is not reliable in detecting iron deficiency in this setting, whereas transferrin saturation seems more appropriate for this purpose. Besides, lack of bioavailable iron can be further worsened by the use of erythropoiesis stimulating agents that increase iron utilization in the bone marrow. Iron deficiency can cause anemia or worsen pre-existing anemia, leading to a decline in performance status and adherence to treatment, with possible implications in clinical outcome. Due to its frequency and importance, treatment of this condition is already recommended in many specialty guidelines and should be performed preferably with intravenous iron. The evidences regarding the efficacy of this treatment are solid, with response gain when combined with erythropoiesis stimulating agents and significant increments in hemoglobin as monotherapy. Among intravenous iron formulations, slow release preparations present more favorable pharmacological characteristics and efficacy in cancer patients.

Abstract
Iron deficiency and iron deficiency-associated anemia are common complications in cancer patients. Most iron deficient cancer patients present with functional iron deficiency (FID), a status with adequate storage iron, but insufficient iron supply for erythroblasts and other iron dependent tissues. FID is the consequence of the cancer-associated cytokine release, while in absolute iron deficiency iron stores are depleted resulting in similar but often more severe symptoms of insufficient iron supply. Here we present a short review on the epidemiology, pathophysiology, diagnosis, clinical symptoms, and treatment of iron deficiency in cancer patients. Special emphasis is given to intravenous iron supplementation and on the benefits and limitations of different formulations. Based on these considerations and recommendations from current international guidelines we developed recommendations for clinical practice and classified the level of evidence and grade of recommendation according to the principles of evidence-based medicine.

Switching patients with non-dialysis chronic kidney disease from oral iron to intravenous ferric carboxymaltose: effects on erythropoiesis-stimulating agent requirements, costs, hemoglobin and iron status. PLoS One 2015; 10:e0125528. [PMID: 25928811 PMCID: PMC4415953 DOI: 10.1371/journal.pone.0125528] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2014] [Accepted: 03/06/2015] [Indexed: 11/20/2022] Open
Abstract
Background Patients with non-dialysis-dependent chronic kidney disease (ND-CKD) often receive an erythropoiesis-stimulating agent (ESA) and oral iron treatment. This study evaluated whether a switch from oral iron to intravenous ferric carboxymaltose can reduce ESA requirements and improve iron status and hemoglobin in patients with ND-CKD. Methods This prospective, single arm and single-center study included adult patients with ND-CKD (creatinine clearance ≤40 mL/min), hemoglobin 11–12 g/dL and iron deficiency (ferritin <100 μg/L or transferrin saturation <20%), who were regularly treated with oral iron and ESA during 6 months prior to inclusion. Study patients received an intravenous ferric carboxymaltose dose of 1,000 mg iron, followed by a 6-months ESA/ ferric carboxymaltose maintenance regimen (target: hemoglobin 12 g/dL, transferrin saturation >20%). Outcome measures were ESA dose requirements during the observation period after initial ferric carboxymaltose treatment (primary endpoint); number of hospitalizations and transfusions, renal function before and after ferric carboxymaltose administration, number of adverse reactions (secondary endpoints). Hemoglobin, mean corpuscular volume, ferritin and transferrin saturation were measured monthly from baseline until end of study. Creatinine clearance, proteinuria, C-reactive protein, aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase bimonthly from baseline until end of study. Results Thirty patients were enrolled (age 70.1±11.4 years; mean±SD). Mean ESA consumption was significantly reduced by 83.2±10.9% (from 41,839±3,668 IU/patient to 6,879±4,271 IU/patient; p<0.01). Hemoglobin increased by 0.7±0.3 g/dL, ferritin by 196.0±38.7 μg/L and transferrin saturation by 5.3±2.9% (month 6 vs. baseline; all p<0.01). No ferric carboxymaltose-related adverse events were reported and no patient withdrew or required transfusions during the study. Conclusion Among patients with ND-CKD and stable normal or borderline hemoglobin, switching from oral iron to intravenous ferric carboxymaltose was associated with significant improvements in hematological and iron parameters and a significant reduction in ESA dose requirements in this single-center pilot study.

Abstract
Background Rigorous data are sparse concerning the optimal route of administration and dosing strategy for iron therapy with or without concomitant erythropoiesis-stimulating agent (ESA) therapy for the management of iron deficiency anaemia in patients with non-dialysis dependent chronic kidney disease (ND-CKD). Methods FIND-CKD was a 56-week, open-label, multicentre, prospective, randomized three-arm study (NCT00994318) of 626 patients with ND-CKD and iron deficiency anaemia randomized to (i) intravenous (IV) ferric carboxymaltose (FCM) at an initial dose of 1000 mg iron with subsequent dosing as necessary to target a serum ferritin level of 400–600 µg/L (ii) IV FCM at an initial dose of 200 mg with subsequent dosing as necessary to target serum ferritin 100–200 µg/L or (iii) oral ferrous sulphate 200 mg iron/day. The primary end point was time to initiation of other anaemia management (ESA therapy, iron therapy other than study drug or blood transfusion) or a haemoglobin (Hb) trigger (two consecutive Hb values <10 g/dL without an increase of ≥0.5 g/dL). Results The background, rationale and study design of the trial are presented here. The study has been completed and results are expected in late 2013. Discussion FIND-CKD was the longest randomized trial of IV iron therapy to date. Its findings will address several unanswered questions regarding iron therapy to treat iron deficiency anaemia in patients with ND-CKD. It was also the first randomized trial to utilize both a high and low serum ferritin target range to adjust IV iron dosing, and the first not to employ Hb response as its primary end point.

Prevention of blood transfusion with intravenous iron in gynecologic cancer patients receiving platinum-based chemotherapy. Gynecol Oncol 2013; 131:679-82. [PMID: 24099839 DOI: 10.1016/j.ygyno.2013.09.028] [Citation(s) in RCA: 27] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2013] [Revised: 09/24/2013] [Accepted: 09/27/2013] [Indexed: 12/21/2022]
Abstract
OBJECTIVES To compare the efficacy of intravenous iron and oral iron for prevention of blood transfusions in gynecologic cancer patients receiving platinum-based chemotherapy. MATERIALS AND METHODS Sixty-four non anemic gynecologic cancer patients receiving adjuvant platinum-based chemotherapy were stratified and randomized according to baseline hemoglobin levels and chemotherapy regimen. The study group received 200mg of intravenous iron sucrose immediately after each chemotherapy infusion. The control group received oral ferrous fumarate at a dose of 200mg three times a day. Complete blood count was monitored before each chemotherapy infusion. Blood transfusions were given if hemoglobin level was below 10mg/dl. RESULTS There were 32 patients in each group. No significant differences in baseline hemoglobin levels and baseline characteristics were demonstrated between both groups. Nine patients (28.1%) in the study group and 18 patients (56.3%) in the control group required blood transfusion through 6 cycles of chemotherapy (p=0.02). Fewer median number of total packed red cell units were required in the study group compared to the control group (0 and 0.5 unit, respectively, p=0.04). Serious adverse events and hypersensitivity reactions were not reported. However, constipation was significantly higher in the control group (3.1% and 40.6%, p=<0.001). CONCLUSIONS Intravenous iron is an effective, well-tolerated treatment for primary prevention of blood transfusions in gynecologic cancer patients receiving platinum-based chemotherapy, associated with less constipation than the oral formulation.
