Abstract
PURPOSE Iron deficiency anemia is common in people with inflammatory bowel disease (IBD), causing deterioration in quality of life, which can be reversed by treatment that increases iron stores and hemoglobin levels. The present post hoc analyses estimate health state utility values for patients with IBD after treatment with ferric derisomaltose or ferric carboxymaltose and evaluate the health domains driving the changes. METHODS SF-36v2 responses were recorded at baseline and day 14, 35, 49, and 70 from 97 patients enrolled in the randomized, double-blind, PHOSPHARE-IBD trial (ClinicalTrials.gov ID: NCT03466983), in which patients with IBD across five European countries were randomly allocated to either ferric derisomaltose or ferric carboxymaltose. Changes in SF-36v2 scale scores and SF-6Dv2 health utility values were analyzed by mixed models. RESULTS In both treatment arms, SF-6Dv2 utility values and all SF-36v2 scale scores, except Bodily Pain, improved significantly (p = < 0.0001). The improvement in SF-6Dv2 utility values showed no significant treatment group difference. The improvement in utility values was completely explained by improvement in Vitality scores. Vitality scores showed significantly larger improvement with ferric derisomaltose versus ferric carboxymaltose (p = 0.026). Patients with the smallest decrease in phosphate had significantly larger improvements in Vitality scores at each time point (p = < 0.05 for all comparisons) and overall (p = 0.0006). CONCLUSIONS Utility values improved significantly with intravenous iron treatment. Improvement in utility values was primarily driven by Vitality scores, which showed significantly greater improvement in the ferric derisomaltose arm. Smaller decreases in phosphate were associated with significantly higher Vitality scores, suggesting that quality of life improvement is attenuated by hypophosphatemia. The utility values can inform future cost-utility analysis.

Cost-utility analysis of ferric derisomaltose versus ferric carboxymaltose in patients with inflammatory bowel disease and iron deficiency anemia in England. J Med Econ 2024; 27:392-403. [PMID: 38391240 DOI: 10.1080/13696998.2024.2313932] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Accepted: 01/31/2024] [Indexed: 02/24/2024]
Abstract
AIMS Anemia is the most common extraintestinal complication of inflammatory bowel disease (IBD), with approximately half of cases caused by iron deficiency (ID). Intravenous iron is the preferred ID anemia (IDA) treatment where oral iron is contraindicated, ineffective or not tolerated, or where ID correction is urgent. The objective was to evaluate the cost-utility of ferric derisomaltose (FDI) versus ferric carboxymaltose (FCM) in patients with IBD and IDA in England, in whom IV iron treatment is preferred. MATERIALS AND METHODS A patient-level simulation model was developed, capturing quality of life (QoL) differences based on SF-36v2 data from the PHOSPHARE-IBD randomized controlled trial, monitoring and incidence of post-infusion hypophosphatemia, and number of iron infusions required. Analyses were conducted over a five-year time horizon from the Department of Health and Social Care (DHSC) perspective, with healthcare provider and societal perspectives adopted in separate analyses. Future costs and effects were discounted at 3.5% per annum and one-way and probabilistic sensitivity analyses were performed. RESULTS FDI increased quality-adjusted life expectancy by 0.075 QALYs versus FCM from 2.57 QALYs to 2.65 QALYs per patient. Patients receiving FDI required 1.63 fewer iron infusions over the five-year time horizon, driving infusion-related cost savings of GBP 496 per patient (GBP 2,188 versus GBP 1,692) from the DHSC perspective. Costs of monitoring and treating hypophosphatemia after FCM were GBP 226, yielding total savings of GBP 722 per patient (GBP 2,414 versus GBP 1,692) over the five-year time horizon. FDI also led to reduced costs versus FCM in the societal and provider analyses and was therefore the dominant intervention across all three perspectives. LIMITATIONS The analysis did not capture patient adherence, hypophosphatemic osteomalacia, or fractures. CONCLUSIONS Results showed that FDI improved patient QoL and reduced direct healthcare expenditure versus FCM in patients with IBD and IDA in England.

Abstract
Many patients experiencing acute gastrointestinal bleeding (GIB) require iron supplementation to treat subsequent iron deficiency (ID) or iron-deficiency anemia (IDA). Guidelines regarding management of these patients are lacking. We aimed to identify areas of unmet need in patients with ID/IDA following acute GIB in terms of patient management and physician guidance. We formed an international working group of gastroenterologists to conduct a narrative review based on PubMed and EMBASE database searches (from January 2000 to February 2021), integrated with observations from our own clinical experience. Published data on this subject are limited and disparate, and those relating to post-discharge outcomes, such as persistent anemia and re-hospitalization, are particularly lacking. Often, there is no post-discharge follow-up of these patients by a gastroenterologist. Acute GIB-related ID/IDA, however, is a prevalent condition both at the time of hospital admission and at hospital discharge and is likely underdiagnosed and undertreated. Despite limited data, there appears to be notable variation in the prescribing of intravenous (IV)/oral iron regimens. There is also some evidence suggesting that, compared with oral iron, IV iron may restore iron levels faster following acute GIB, have a better tolerability profile, and be more beneficial in terms of quality of life. Gaps in patient care exist in the management of acute GIB-related ID/IDA, yet further data from large population-based studies are needed to confirm this. We advocate the formulation of evidence-based guidance on the use of iron therapies in these patients, aiding a more standardized best-practice approach to patient care.

Intravenous iron sucrose vs. blood transfusion in the management of moderate postpartum iron deficiency anemia: A non-randomized quasi-experimental study. Heliyon 2022; 8:e08980. [PMID: 35243098 PMCID: PMC8866052 DOI: 10.1016/j.heliyon.2022.e08980] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2021] [Revised: 01/08/2022] [Accepted: 02/14/2022] [Indexed: 11/28/2022] Open
Abstract
INTRODUCTION Postpartum anemia is often over-treated with blood transfusion without clear indication despite having a potential alternative of parenteral iron therapy. The present study aimed to compare the efficacy of intravenous (IV) iron sucrose with blood transfusion in increasing the hematological parameters in postpartum women with moderate anemia. METHODS This prospective non-randomized quasi-experimental study was conducted among 44 hemodynamically stable postpartum women with moderate anemia (Hb 7-8 g/dl) in the Obstetrics department of Dhaka Medical College Hospital (DMCH) from January to June 2021. Among them, 22 patients received 600 mg of IV iron sucrose after 48 h of delivery for three subsequent days and the other 22 patients received two units of blood transfusion after 48 h of delivery in two subsequent days. The primary endpoint was increase in Hemoglobin (Hb) and serum ferritin level after 6 weeks of the intervention. Two-way repeated measures ANOVA (mixed factor ANOVA) was applied to compare between before and after effect in the two intervention groups. RESULTS Baseline Hb and ferritin were 7.4 g/dl and 73.5 μg/l in IV iron group and 7.3 g/dl and 73.2 μg/l in blood transfusion group. Mean Hb level was increased 4.2 g/dl in IV iron sucrose group and 4.5 g/dl in blood transfusion group at sixth week. Besides, serum ferritin level was increased 40.5 μg/l and 44.8 μg/l after six weeks in IV iron sucrose group and blood transfusion group respectively. Other hematological parameters like reticulocyte count, MCV, MCH, and MCHC also increased significantly after intervention in both groups. However, no significant difference was noticed in the change of hematological parameters in between the groups. CONCLUSIONS The IV iron sucrose is as effective as blood transfusion in replenishing the hemoglobin and iron storage status in hemodynamically stable women with moderate post-partum anemia. This could be an effective alternative of blood transfusion in treating these patients, especially in resource-poor settings.

Obes Surg 2022; 32:810-818. [PMID: 35000068 PMCID: PMC8866325 DOI: 10.1007/s11695-021-05858-0] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2021] [Revised: 12/15/2021] [Accepted: 12/17/2021] [Indexed: 11/30/2022]
Abstract
Purpose Iron deficiency is common following bariatric surgery, and treatment with intravenous iron is often required. This post hoc analysis of data from two randomized, open-label, multicenter trials evaluated the efficacy and safety of ferric derisomaltose (FDI; formerly iron isomaltoside 1000) versus iron sucrose (IS) over 4 weeks in adults with iron deficiency anemia (IDA) resulting from prior bariatric surgery. Materials and methods Data were pooled for participants who received FDI or IS in the PROVIDE or FERWON-IDA trials for the treatment of IDA post bariatric surgery. Efficacy outcomes included changes in hemoglobin (Hb) and iron parameters; safety outcomes included the incidence of adverse drug reactions (ADRs), serious or severe hypersensitivity reactions (HSRs), and hypophosphatemia. Results The analysis included 159 patients. Mean (standard deviation) cumulative iron doses were 1199 (± 347) mg for FDI and 937 (± 209) mg for IS. Compared with IS, FDI resulted in a faster and more pronounced Hb response, and a higher proportion of responders (Hb level increase ≥ 2 g/dL from baseline) at all time points. The incidence of ADRs was similar with FDI and IS (15.1% and 18.2%, respectively), with no serious ADRs or serious or severe HSRs reported. The incidence of hypophosphatemia was low and similar in both treatment groups, with no cases of severe hypophosphatemia observed. Conclusions In patients with IDA resulting from bariatric surgery, FDI produced a faster and more pronounced Hb response than IS. Both FDI and IS were well tolerated. Graphical abstract ![]()

Abstract
Background In Australia, iron deficiency anaemia can be managed by ferric carboxymaltose, and iron polymaltose given via either a traditional slow or new rapid infusion protocol. These differ in their manufacturing, administration, and monitoring requirements, with unknown associated costs. Aim To compare the direct costs of iron infusions used in Australia; and explore potential savings associated with increased uptake of the least-expensive option at a local hospital. Method A time-motion method was used to determine the labour and consumables associated with each infusion protocol. Secondly, a frequency analysis identified the most common iron infusion doses prescribed at the study site. The total direct costs per protocol were compared at these doses and then the potential savings from switching to the lowest-costing of these protocols where possible were explored. Results The most common doses were 0.5 g, 1 g, 1.5 g and 2 g. At these dose points, ferric carboxymaltose infusions are the least expensive, but only if national health subsidies are applied. In cases where they do not apply, iron polymaltose prepared from ampoules and infused using the rapid protocol ('Iron Polymaltose Ampoules Rapid') is the least expensive. Switching all applicable ferric carboxymaltose infusions and iron polymaltose infusions administered using the slow infusion protocol to Iron Polymaltose Ampoules Rapid is projected to yield up to $12,000 worth of savings annually. Conclusions Increased use of the Iron Polymaltose Ampoules Rapid protocol when government-subsidised options are not available is projected to have cost-saving outcomes. Investigation of implementation strategies to increase the use of this protocol are warranted.
