Caljé E, Groom KM, Dixon L, Marriott J, Foon R, Oyston C, Bloomfield FH, Jordan V. Intravenous iron versus blood transfusion for postpartum anemia: a systematic review and meta-analysis. Syst Rev 2024; 13:9. [PMID: 38169415 PMCID: PMC10759729 DOI: 10.1186/s13643-023-02400-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Accepted: 11/22/2023] [Indexed: 01/05/2024] Open
Abstract
BACKGROUND Intravenous iron (IV-iron) is used as an alternative to, or alongside, red blood cell transfusion (RBC-T) to treat more severe postpartum anemia (PPA), although optimal treatment options remain unclear. No previous systematic reviews have examined IV-iron and RBC-T, including patient-reported outcomes and hematological responses. METHODS A systematic review and meta-analysis of randomized trials comparing IV-iron and RBC-T with each other, oral iron, no treatment, and placebo for the treatment of PPA. Key inclusion criteria were PPA (hemoglobin < 12 g/dL) and IV-iron or RBC-T as interventions. Key exclusion criteria were antenatal IV-iron or RBC-T. Fatigue was the primary outcome. Secondary outcomes included hemoglobin and ferritin concentrations, and adverse events. From 27th August 2020 to 26th September 2022, databases, registries, and hand searches identified studies. A fixed-effect meta-analysis was undertaken using RevMan (5.4) software. The quality of the studies and the evidence was assessed using the Cochrane Risk of Bias table, and Grading of Recommendations, Assessment, Development, and Evaluation. This review is registered with the Prospective Register of Systematic Reviews (CRD42020201115). RESULTS Twenty studies and 4196 participants were included: 1834 assigned IV-iron, 1771 assigned oral iron, 330 assigned RBC-T, and 261 assigned non-intervention. Six studies reported the primary outcome of fatigue (1251 participants). Only studies of IV-iron vs. oral iron (15 studies) were available for meta-analysis. Of these, three reported on fatigue using different scales; two were available for meta-analysis. There was a significant reduction in fatigue with IV-iron compared to oral iron (standardized mean difference - 0.40, 95% confidence interval (CI) - 0.62, - 0.18, I2 = 0%). The direction of effect also favored IV-iron for hemoglobin (mean difference (MD) 0.54 g/dL, 95% confidence interval (CI) 0.47, 0.61, I2 = 91%), ferritin, (MD 58.07 mcg/L, 95% CI 55.74, 60.41, I2 = 99%), and total adverse events (risk-ratio 0.63, 95% CI 0.52, 0.77, I2 = 84%). The overall quality of the evidence was low-moderate. DISCUSSION For all outcomes, the evidence for RBC-T, compared to IV-iron, non-intervention, or dose effects of RBC-T is very limited. Further research is needed to determine whether RBC-T or IV-iron for the treatment of PPA is superior for fatigue and hematological outcomes.

Abstract
BACKGROUND Postpartum iron deficiency anemia (PPIDA) is highly prevalent in developing countries where it constitutes an important cause of maternal morbidity and mortality. Potential determinants of PPIDA are prepartum iron deficiency or iron deficiency anemia in association with severe blood loss during delivery. We investigated the efficacy of oral Sucrosomial® iron for recover from mild-to-moderate PPIDA. METHODS This pilot study was conducted in three medical centers in Romania. Adult women (≥ 18y) with mild (hemoglobin [Hb] 9-11 g/dL) or moderate (Hb 7-9 g/dL) PPIDA diagnosed at screening (2-24 h after delivery) were eligible. Women with mild PPIDA received oral Sucrosomial® iron (Pharmanutra, S.p.A, Italy) once daily (30 mg elemental iron per capsule) for 60 days. Those with moderate PPIDA received oral Sucrosomial® iron twice daily (60 mg elemental iron) for 10 days, followed by a 50-day course of oral Sucrosomial® iron once daily (30 mg elemental iron). Laboratory parameters, as well as subjective clinical symptoms using a 3-point Likert Scale, were assessed at baseline and on study days 10, 30 and 60. RESULTS Sixty anemic women entered the study, but three were missed during follow-up. At day 60, a Hb rise was observed in both groups (+ 3.6 ± 1.5 g/dL; p < 0.01), 81% experienced correction of anemia (Hb ≥ 12 g/dL), 36% achieved a ferritin concentration ≥ 30 ng/mL (p < 0.05), and 54% a transferrin saturation (TSAT) ≥ 20% (p < 0.01). For women still anemic at day 60, mean Hb was close to normality (11.3 ± 0.8 g/dL). Resolution of IDA-associated clinical symptoms was already observed just 10 days after treatment initiation. No patient discontinued treatment due to gastrointestinal adverse events. CONCLUSIONS Sucrosomial® iron was shown to be potentially effective and well tolerated at treating mild and moderate PPIDA. These results encourage the use of oral Sucrosomial® iron as a treatment option for PPIDA, but larger studies with longer follow-up are warrant.

Abstract
BACKGROUND Iron supplementation is administered orally or intravenously to treat iron-deficiency anemia (IDA). Ferric Carboxymaltose (FCM) "Ferinject®" is an intravenous (IV) iron preparation that has emerged as a safe therapeutic option for treating IDA in the past decade. AIM This study aimed to evaluate safety and efficacy of carboxymaltose in a cohort of patients with IDA not responding to oral therapy. METHODS This 12-month retrospective study included 106 patients with IDA, with-or without bariatric surgery, who received (single or multiple doses) of Carboxymaltose 500mg/10mL. Data points included patients' demographics, baseline data for Hb, platelet, ferritin, and MCV pre-and at 1, 2, and 3 months following different doses of IV-Carboxymaltose. Changes in Hb, MCV, platelets, and ferritin levels were recorded in response to Carboxymaltose to assess the optimal dose, risk of hyperferritinemia, and hypophosphatemia. RESULTS At three months (95 days) follow-up, the median change pre-and post-therapy in hemoglobin was from 9.5 to 11.9g/dL (p < 0.01), MCV 73.6-80.5fL (p < 0.01), and ferritin 5.3-93.8ng/mL. A significant difference was observed between platelet count of patients who underwent bariatric surgery and those who did not. An optimal ferritin response (>30ng/mL) was observed in 87.8% of patients who received first dose, and none of the full three doses showed no response. 37% of patients who received two doses developed hyperferritinemia. Serum phosphate levels were assessed in 28 cases, and hypophosphatemia was observed in 25% of these patients. CONCLUSION Carboxymaltose is a reliable option for IDA. IV-FCM therapy helps achieve significant improvement in hemoglobin concentration and MCV from the first dose carrying a low reversible risk of hyperferritinemia following multiple doses. An interesting finding of this study is the discovery of a population of IDA patients requiring periodic assessment for iron reinfusion to sustain normal levels, mostly post-bariatric surgery. Changes in serum phosphate levels reported to occur consecutively with FCM treatment should be further studied.

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
IMPORTANCE Intravenous iron is recommended by many clinical guidelines based largely on its effectiveness in reducing anemia. However, the association with important safety outcomes, such as infection, remains uncertain. OBJECTIVE To examine the risk of infection associated with intravenous iron compared with oral iron or no iron. DATA SOURCES Medline, Embase, and Cochrane Central Register of Controlled Trials (CENTRAL) were searched for randomized clinical trials (RCTs) from 1966 to January 31, 2021. Ongoing trials were sought from ClinicalTrials.gov, CENTRAL, and the World Health Organization International Clinical Trials Search Registry Platform. STUDY SELECTION Pairs of reviewers identified RCTs that compared intravenous iron with oral iron or no iron across all patient populations, excluding healthy volunteers. Nonrandomized studies published since January 1, 2007, were also included. A total of 312 full-text articles were assessed for eligibility. DATA EXTRACTION AND SYNTHESIS Data extraction and risk of bias assessments were performed according to the Preferred Reporting Items of Systematic Reviews and Meta-analyses (PRISMA) and Cochrane recommendations, and the quality of evidence was assessed using the GRADE (Grades of Recommendation, Assessment, Development, and Evaluation) approach. Two reviewers extracted data independently. A random-effects model was used to synthesize data from RCTs. A narrative synthesis was performed to characterize the reporting of infection. MAIN OUTCOMES AND MEASURES The primary outcome was risk of infection. Secondary outcomes included mortality, hospital length of stay, and changes in hemoglobin and red blood cell transfusion requirements. Measures of association were reported as risk ratios (RRs) or mean differences. RESULTS A total of 154 RCTs (32 920 participants) were included in the main analysis. Intravenous iron was associated with an increased risk of infection when compared with oral iron or no iron (RR, 1.17; 95% CI, 1.04-1.31; I2 = 37%; moderate certainty of evidence). Intravenous iron also was associated with an increase in hemoglobin (mean difference, 0.57 g/dL; 95% CI, 0.50-0.64 g/dL; I2 = 94%) and a reduction in the risk of requiring a red blood cell transfusion (RR, 0.93; 95% CI, 0.76-0.89; I2 = 15%) when compared with oral iron or no iron. There was no evidence of an effect on mortality or hospital length of stay. CONCLUSIONS AND RELEVANCE In this large systematic review and meta-analysis, intravenous iron was associated with an increased risk of infection. Well-designed studies, using standardized definitions of infection, are required to understand the balance between this risk and the potential benefits.

Abstract
The effectiveness of intravenous ferric carboxymaltose (FCM) in quickly increasing normal hemoglobin concentration and replenishing body iron reserves up to 6-12 wk is known; however, its long-term effectiveness is unknown. In this study conducted in northern India during August 2018 to February 2019, 100 postpartum women within 48 h of delivery with a hemoglobin concentration between 5.0 and 9.9 g/dL were included. A single dose of intravenous FCM was administered. The hemoglobin and serum ferritin concentrations were measured at baseline and at 6 mo. Out of 100 women recruited, 57 (57%) returned for the follow-up visit at 6 mo. The mean (± SD) hemoglobin and serum ferritin concentrations at baseline were 8.6 ± 1.1 g/dL and 15.8 ± 17.2 ng/mL, respectively, and at 6 months were 12.5 ± 1.2 g/dL and 72.0 ± 52.0 ng/mL, respectively. The mean increase in hemoglobin concentration was 3.9 (95% CI: 3.5, 4.3) g/dL (P < 0.001) and for serum ferritin was 53.8 (95% CI: 41.8, 65.8) ng/mL (P < 0.001). The study was registered prospectively in the Clinical Trials Registry-India (CTRI) as CTRI/2018/06/014332.

Abstract
Restless legs syndrome (RLS) affects about 20% of all pregnant women. RLS symptoms are usually moderate to severe in intensity during pregnancy and can result in insomnia, depression, and other adverse outcomes. Although iron deficiency has been implicated as a potential etiological factor, other mechanisms can also play a role. Nonpharmacologic methods are the primary recommended form of treatment for RLS in pregnancy and lactation. Iron supplementation may be considered when the serum ferritin is low; however, several patients are unable to tolerate iron or have severe symptoms despite oral iron replacement. Here, we describe a case of severe RLS in pregnancy and illustrate the dilemmas in diagnosis and management. We review the literature on the prevalence, diagnosis, course, possible underlying pathophysiologic mechanisms and complications of RLS in pregnancy. We describe current best evidence on the efficacy, and safety of nonpharmacologic therapies, oral and intravenous iron supplementation, as well as other medication treatments for RLS in pregnancy and lactation. We highlight gaps in the literature and provide a practical guide for the clinical management of RLS in pregnancy and during breastfeeding.

Abstract
INTRODUCTION Iron deficiency anemia (IDA) is common among obstetric and gynecologic patients. This systematic review aimed to assess the comparative efficacy and safety of commonly used intravenous (IV) iron formulations, ferric carboxymaltose (FCM), and iron sucrose (IS) in the treatment of IDA in obstetric and gynecologic patients. METHODS We systematically searched PubMed, EMBASE, Cochrane CENTRAL, and Google Scholar for eligible randomized controlled trials (RCTs) comparing IV iron replacement using FCM and IS up to October 2019. The primary outcome was to compare the efficacy of FCM and IS, assessed by measuring serum hemoglobin (Hb) and ferritin levels before and after iron replacement. The secondary outcome was to compare the safety of FCM and IS, assessed by the incidence of adverse events during iron replacement. The meta-analysis was performed using RevMan 5.3. RESULTS We identified 9 RCTs with 910 patients (FCM group, n = 456; IS group, n = 454). Before iron replacement, FCM and IS group patients had similar baseline Hb (mean difference [MD], 0.04 g/dL; 95% confidence interval [CI], -0.07 to 015; I2 = 0%; P = 0.48) and ferritin levels (MD, -0.42 ng/mL; 95% CI, -1.61 to 0.78; I2 = 45%; P = 0.49). Following iron replacement, patients who received FCM had higher Hb (MD, 0.67; 95% CI, 0.25-1.08; I2 = 92%; P = 0.002) and ferritin levels (MD, 24.41; 95% CI, 12.06-36.76; I2 = 75%; P = 0.0001) than patients who received IS. FCM group showed a lower incidence of adverse events following iron replacement than IS group (risk ratio, 0.53; 95% CI, 0.35-0.80; I2 = 0%; P = 0.003). Serious adverse events were not reported in any group. CONCLUSION FCM group showed better efficacy in increasing Hb and ferritin levels and a favorable safety profile with fewer adverse events compared with IS group for IDA treatment among obstetric and gynecologic patients. However, this meta-analysis was limited by the small number of RCTs and high heterogeneity. TRIAL REGISTRATION The review was prospectively registered with the International Prospective Registry of Systematic Reviews (https://www.crd.york.ac.uk/prospero/, registration number CRD42019148905).

Abstract
OBJECTIVE To examine the feasibility of developing an in-reach parenteral iron infusion service to residents of residential aged care facilities (RACFs). METHODS An audit comparing the use of iron infusions in RACFs prior to and following the introduction of an in-reach iron infusion service. RESULTS Of the 738 inpatient iron infusions administered to inpatients ≥65 years in the 12 months prior to the in-reach service, 52 (7%) lived in an RACF, with no significant adverse events reported. After implementation of an in-reach service, a total of 37 RACF residents received parenteral iron in the first 12 months of the service, with no significant adverse events reported. CONCLUSION It is possible to safely provide parenteral iron through an in-reach service to residents in RACF. Further research is required to identify the person-level benefits achieved by this service.

Abstract
BACKGROUND Preoperative anaemia is common and occurs in 5% to 76% of patients preoperatively. It is associated with an increased risk of perioperative allogeneic blood transfusion, longer hospital stay, and increased morbidity and mortality. Iron deficiency is one of the most common causes of anaemia. Oral and intravenous iron therapy can be used to treat anaemia. Parenteral iron preparations have been shown to be more effective in conditions such as inflammatory bowel disease, chronic heart failure and postpartum haemorrhage due to rapid correction of iron stores. A limited number of studies has investigated iron therapy for the treatment of preoperative anaemia. The aim of this Cochrane Review is to summarise the evidence for iron supplementation, both enteral and parenteral, for the management of preoperative anaemia. OBJECTIVES To evaluate the effects of preoperative iron therapy (enteral or parenteral) in reducing the need for allogeneic blood transfusions in anaemic patients undergoing surgery. SEARCH METHODS We ran the search on 30 July 2018. We searched the Cochrane Injuries Group's Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL, the Cochrane Library), Ovid MEDLINE(R), Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) Daily and Ovid OLDMEDLINE(R), Embase Classic and Embase (Ovid), CINAHL Plus (EBSCO), PubMed, and clinical trials registries, and we screened reference lists. We ran a top-up search on 28 November 2019; one study is now awaiting classification. SELECTION CRITERIA We included all randomised controlled trials (RCTs) that compared preoperative iron monotherapy to placebo, no treatment, standard care or another form of iron therapy for anaemic adults undergoing surgery. We defined anaemia as haemoglobin values less than 13 g/dL for males and 12 g/dL for non-pregnant females. DATA COLLECTION AND ANALYSIS Two review authors collected data and a third review author checked all collected data. Data were collected on the proportion of patients who receive a blood transfusion, the amount of blood transfused per patient (units), quality of life, ferritin levels and haemoglobin levels, measured as continuous variables at the following predetermined time points: pretreatment (baseline), preoperatively but postintervention, and postoperatively. We performed statistical analysis using the Cochrane software, Review Manager 5. We summarised outcome data in tables and forest plots. We used the GRADE approach to describe the quality of the body of evidence. MAIN RESULTS Six RCTs, with a total of 372 participants, evaluated preoperative iron therapy to correct anaemia before planned surgery. Four studies compared iron therapy (either oral (one study) or intravenous (three studies)) with no treatment, placebo or usual care, and two studies compared intravenous iron therapy with oral iron therapy. Iron therapy was delivered over a range of periods that varied from 48 hours to three weeks prior to surgery. The 372 participants in our analysis fall far short of the 819 required - as calculated by our information size calculation - to detect a 30% reduction in blood transfusions. Five trials, involving 310 people, reported the proportion of participants who received allogeneic blood transfusions. Meta-analysis of iron therapy versus placebo or standard care showed no difference in the proportion of participants who received a blood transfusion (risk ratio (RR) 1.21, 95% confidence interval (CI) 0.87 to 1.70; 4 studies, 200 participants; moderate-quality evidence). Only one study that compared oral versus intravenous iron therapy measured this outcome, and reported no difference in risk of transfusion between groups. There was no difference between the iron therapy and placebo/standard care groups for haemoglobin level preoperatively at the end of the intervention (mean difference (MD) 0.63 g/dL, 95% CI -0.07 to 1.34; 2 studies, 83 participants; low-quality evidence). However, intravenous iron therapy produced an increase in preoperative postintervention haemoglobin levels compared with oral iron (MD 1.23 g/dL, 95% CI 0.80 to 1.65; 2 studies, 172 participants; low-quality evidence). Ferritin levels were increased by intravenous iron, both when compared to standard care ((MD 149.00, 95% CI 25.84 to 272.16; 1 study, 63 participants; low-quality evidence) or to oral iron (MD 395.03 ng/mL, 95% CI 227.72 to 562.35; 2 studies, 151 participants; low-quality evidence). Not all studies measured quality of life, short-term mortality or postoperative morbidity. Some measured the outcomes, but did not report the data, and the studies which did report the data were underpowered. Therefore, uncertainty remains regarding these outcomes. The inclusion of new research in the future is very likely to change these results. AUTHORS' CONCLUSIONS The use of iron therapy for preoperative anaemia does not show a clinically significant reduction in the proportion of trial participants who received an allogeneic blood transfusion compared to no iron therapy. Results for intravenous iron are consistent with a greater increase in haemoglobin and ferritin when compared to oral iron, but do not provide reliable evidence. These conclusions are drawn from six studies, three of which included very small numbers of participants. Further, well-designed, adequately powered, RCTs are required to determine the true effectiveness of iron therapy for preoperative anaemia. Two studies are currently in progress, and will include 1500 randomised participants.

Comparative efficacy and safety of intravenous ferric carboxymaltose and iron sucrose for the treatment of preoperative anemia in patients with menorrhagia: An open-label, multicenter, randomized study. J Obstet Gynaecol Res 2019; 45:858-864.

Abstract
AIM To compare ferric carboxymaltose (FCM) with iron sucrose (IS) for the effective and timely treatment of preoperative iron deficiency anemia (IDA) in women with menorrhagia. METHODS This open-label, multicenter, two-arm study randomized patients to receive either a single dose of FCM or multiple doses of IS. The primary endpoint was the proportion of patients who achieved hemoglobin (Hb) levels ≥10 g/dL within 2 weeks after the first administration. Secondary endpoints included mean Hb levels, time to reach Hb ≥10 g/dL and quality of life (QoL). RESULTS In total, 101 patients (FCM n = 52; IS n = 49) were randomized to the study treatments. FCM was as effective as IS in achieving Hb ≥10 g/dL within 2 weeks after the first administration (78.8% vs 72.3%). The time to reach Hb ≥10 g/dL was significantly shorter in the FCM group than in the IS group (7.7 days vs 10.5 days). Mean Hb levels were higher in the FCM-treated patients than in the IS-treated patients with borderline significance. QoL scores did not differ between the two groups. CONCLUSION Ferric carboxymaltose is as effective as IS in correcting preoperative IDA among patients with menorrhagia. The added benefits of FCM over IS included significant rapid correction of IDA, replenishment of iron stores and reduced hospital visits.

Abstract
BACKGROUND Acute gastrointestinal bleeding is prevalent condition and iron deficiency anaemia is a common comorbidity, yet anaemia treatment guidelines for affected patients are lacking. AIM To compare efficacy and safety of intravenous ferric carboxymaltose (FCM) and oral ferrous sulphate (FeSulf) in patients with anaemia secondary to non-variceal gastrointestinal bleeding METHODS: A prospective 42-day study randomised 61 patients with haemoglobin <10 g/dL upon discharge (Day 0) to receive FCM (n = 29; Day 0: 1000 mg, Day 7: 500 or 1000 mg; per label) or FeSulf (n = 32; 325 mg/12 hours for 6 weeks). Outcome measures were assessed on Days 0 (baseline), 7, 21 and 42. The primary outcome was complete response (haemoglobin ≥12 g/dL [women], ≥13 g/dL [men]) after 6 weeks. RESULTS A higher proportion of complete response was observed in the FCM vs the FeSulf group at Days 21 (85.7% vs 45.2%; P = 0.001) and 42 (100% vs 61.3%; P < 0.001). Additionally, the percentage of patients with partial response (haemoglobin increment ≥2 g/dL from baseline) was significantly higher in the FCM vs the FeSulf group (Day 21:100% vs 67.7%; P = 0.001, Day 42:100% vs 74.2%; P = 0.003). At Day 42, normalisation of transferrin saturation to 25% or greater was observed in 76.9% of FCM vs 24.1% of FeSulf-treated patients (P < 0.001). No patient in the FCM group reported any adverse event vs 10 patients in the FeSulf group. CONCLUSION FCM provided greater and faster Hb increase and iron repletion, and was better tolerated than FeSulf in patients with iron deficiency anaemia secondary to non-variceal acute gastrointestinal bleeding.

Am J Obstet Gynecol 2019; 221:19-29.e3. [PMID: 30578747 DOI: 10.1016/j.ajog.2018.12.016] [Citation(s) in RCA: 52] [Impact Index Per Article: 10.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2018] [Revised: 11/15/2018] [Accepted: 12/08/2018] [Indexed: 12/30/2022]
Abstract
OBJECTIVE To perform a systematic review of randomized trials comparing oral vs intravenous (IV) iron therapy to treat postpartum anemia. DATA SOURCES Data sources were as follows: PubMed (1972-2017); Cochrane Central Register of Controlled Trials, CENTRAL (1972-2017); CINAHL (1972-2017); Web of Science; Excerpta Medica Database, and EMBASE (1972-2017). STUDY ELIGIBILITY CRITERIA We included randomized trials comparing oral vs IV iron monotherapy to treat postpartum anemia (classified as a hemoglobin <12 g/dL). STUDY APPRAISAL AND SYNTHESIS METHODS Study quality was assessed with the Cochrane risk of bias assessment tool. The primary outcome was hemoglobin concentration at 6 weeks postpartum. Secondary outcomes included hemoglobin concentration at 1-5 weeks postpartum, ferritin concentration at 1-6 weeks postpartum, and maternal adverse outcomes. For meta-analysis, mean differences and odds ratios using a random effects model were calculated. Risk of heterogeneity was reported as I2. RESULTS A total of 15 randomized trials met our inclusion criteria (n = 1001 and 1 181 women receiving oral iron and IV iron, respectively); 4 studies reported data for our primary outcome. We observed higher postpartum week 6 hemoglobin concentrations in the IV iron group compared to the oral iron group (mean difference, 0.9 g/dL; 95% confidence interval (CI), 0.4-1.3; P = .0003). Compared to oral iron, women receiving IV iron had higher hemoglobin concentrations at postpartum weeks 1, 2, and 3; higher ferritin concentrations at postpartum weeks 1, 2, 4, and 6; an increased likelihood of skin flushing (odds ratio [OR], 6.95; 95% CI, 1.56-31.03; P = .01; I2 = 0%); and a decreased likelihood of constipation (OR, 0.08; 95% CI, 0.03-0.21; P < .00001, I2 = 27%) and dyspepsia (OR, 0.07; 95% confidence interval, 0.01-0.42; P = .004; I2 = 0%). The reported event rate for anaphylaxis among women receiving IV iron was 0.6%. CONCLUSION In this systematic review, among women with postpartum anemia, hemoglobin concentrations at 6 weeks postpartum were almost 1 g/dL higher in women who received IV iron compared to oral iron. The safety profile of IV iron was also reassuring. Given the weaker hemoglobin response and higher risk of gastrointestinal side effects with oral iron use, our findings suggest that IV iron be considered as a viable treatment option for postpartum iron deficiency anemia.

Abstract
Intravenous ferric carboxymaltose (Ferinject®; Injectafer®) is a colloidal solution of nanoparticles which consist of a polynuclear iron (III)-(oxyhydr)oxide core stabilized by carboxymaltose and may be given as a single high-dose, 15-min infusion. This article reviews the clinical use of ferric carboxymaltose in various patient populations with iron deficiency (ID) [± anaemia] and briefly summarizes its pharmacological properties. Based on extensive experience in the clinical trial and real-world settings, ferric carboxymaltose is an effective and generally well tolerated treatment for rapidly replenishing iron stores and correcting anaemia in patients with ID (± anaemia) of various aetiologies, including patients with chronic heart failure (CHF), chronic kidney disease, inflammatory bowel disease or perioperative anaemia, and women with ID during pregnancy, postpartum or associated with heavy uterine bleeding. As it may be given as a single high-dose infusion, ferric carboxymaltose has the potential to provide cost savings from a healthpayer perspective. Thus, ferric carboxymaltose remains an important option for the treatment of ID in adults and, where approved, children aged ≥ 14 years, when oral iron preparations are ineffective or cannot be used.

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
Purpose To evaluate the efficacy and safety of intravenous ferric carboxymaltose administration to pregnant women with varying severities of iron deficiency anemia and iron deficiency without anemia. Methods In this prospective observational study of local obstetric practice, we analyzed data from 863 pregnant women with iron deficiency according to anemia status and severity. All women were treated with intravenous ferric carboxymaltose in pregnancy. Treatment efficacy was assessed by repeat hemoglobin measurements at 3 and 6 week post-infusion and ferritin levels, where available. Safety was assessed by analysis of adverse events, fetal heart rate monitoring, and newborn health outcome data. Results Ferric carboxymaltose significantly increased hemoglobin in women with mild, moderate, and severe iron deficiency anemia and women with iron deficiency alone at 3 and 6 week post-infusion (p < 0.01 for all). No hemoconcentration occurred in iron-deficient women without anemia. No serious adverse events were recorded, with minor temporary side effects (including local skin irritation, nausea, and headache) occurring in 96 (11%) women. No adverse fetal or neonatal outcomes were observed. Conclusions Ferric carboxymaltose infusion corrects iron deficiency or various degrees of iron deficiency anemia efficaciously and safely pregnant women, and does not cause hemoconcentration.

Abstract
Background This retrospective study was performed to determine whether postoperative intravenous ferric carboxymaltose reduces transfusion amounts without influencing clinical outcomes in patients that have undergone hip surgery. Methods Between May 2014 and April 2016, the authors adopted a new perioperative blood management protocol involving the administration of intravenous ferric carboxymaltose after hip surgeries. One-to-one matching between the 150 patients treated during this period with 150 patients treated before initiation of the new protocol was performed by propensity scoring for age, sex, diagnosis, and type of hip surgery. Hematologic results and clinical outcomes in these two groups were compared. Results Average amounts of perioperative blood loss were not different in the two groups. Ninety-two patients (61%) were transfused in the control group and 70 patients (47%) were transfused in the intravenous ferric carboxymaltose group. The average number of transfused blood units was significantly lower in the intravenous ferric carboxymaltose group (1.7 ± 2.7 units vs. 1.0 ± 1.2 units, p = 0.002). At 6 weeks after surgery, the average hemoglobin concentration recovered to baseline in both groups, but the amount of recovered hemoglobin concentration at 6 weeks was significantly greater in the intravenous ferric carboxymaltose group than in the control group. Clinical outcomes including incidences of postsurgical complications were similar between the two groups. Conclusions This study suggests that postoperative intravenous ferric carboxymaltose injection is associated with reduced transfusion amounts and that intravenous ferric carboxymaltose does not influence clinical outcomes after hip surgery.

Abstract
BACKGROUND Iron deficiency anemia (IDA) is a significant problem worldwide particularly in women. The aim of the study was to evaluate the effectiveness and safety of intravenous ferric carboxymaltose (FCM) in comparison to iron sucrose (IS) in women with IDA. METHOD Two hundred patients at Department of Obstetrics and Gynaecology, Sher-i-Kashmir Institute of Medical Sciences Medical College and Hospital, Jammu & Kashmir, India identified with IDA were enrolled for the study. Intravenous FCM and IS were both given as per the protocol. Change in the laboratory parameters such as hemoglobin (Hb), mean corpuscular value, and serum ferritin levels at two weeks and four weeks interval after the treatment was recorded. RESULT A significant increase in the mean Hb was observed from 7.76 ± 0.709 to 13.25 ± 0.606 in patients treated with FCM and 7.64 ± 0.710 to 11.59 ± 0.733 g/dL (P < 0.001) in patients treated with IS after four weeks of therapy. The rise in mean corpuscular volume was from 66.82 ± 5.24 to 86.76 ± 3.765 and 68.05 ± 5.56 to 93.80 ± 3.80 and rise in serum ferritin levels were from 8.32 ± 1.787 to 38.94 ± 6.095 μg/L and 8.16 ± 1.540 to 27 ± 8.175 μg/L in patients treated with FCM and IS respectively after four weeks of therapy. No serious adverse effects were reported. CONCLUSION Parenteral therapy is effective in IDA, but FCM elevates hemoglobin level and restored iron stores faster than IS with minimum adverse drug reactions.

Abstract
Iron deficiency, with or without anemia, is extremely frequent worldwide, representing a major public health problem. Iron replacement therapy dates back to the seventeenth century, and has progressed relatively slowly until recently. Both oral and intravenous traditional iron formulations are known to be far from ideal, mainly because of tolerability and safety issues, respectively. At the beginning of this century, the discovery of hepcidin/ferroportin axis has represented a turning point in the knowledge of the pathophysiology of iron metabolism disorders, ushering a new era. In the meantime, advances in the pharmaceutical technologies are producing newer iron formulations aimed at minimizing the problems inherent with traditional approaches. The pharmacokinetic of oral and parenteral iron is substantially different, and diversities have become even clearer in light of the hepcidin master role in regulating systemic iron homeostasis. Here we review how iron therapy is changing because of such important advances in both pathophysiology and pharmacology.

Abstract
In patients with heart failure (HF), iron deficiency (ID) correlates with decreased exercise capacity and poor health-related quality of life, and predicts worse outcomes. Both absolute (depleted iron stores) and functional (where iron is unavailable for dedicated tissues) ID can be easily evaluated in patients with HF using standard laboratory tests (assessment of serum ferritin and transferrin saturation). Intravenous iron therapy in iron-deficient patients with HF and reduced ejection fraction has been shown to alleviate HF symptoms and improve exercise capacity and quality of life. In this paper, we provide information on how to diagnose ID in HF. Further we discuss pros and cons of different iron preparations and discuss the results of major trials implementing iron supplementation in HF patients, in order to provide practical guidance for clinicians on how to manage ID in patients with HF.

Abstract
OBJECTIVE To compare the efficacy and safety of intravenous ferric carboxymaltose (FCM) with first-line oral ferrous sulfate (FS) in pregnant women with iron deficiency anemia (IDA). MATERIALS AND METHODS Pregnant women (n=252; gestational weeks 16-33) with IDA were randomized 1:1 to FCM (1000-1500 mg iron) or FS (200 mg iron/day) for 12 weeks. The primary objective was to compare efficacy; secondary objectives included safety and quality of life. RESULTS Hemoglobin (Hb) levels improved at comparable rates across both treatments; however, significantly more women achieved anemia correction with FCM vs. FS [Hb ≥11.0 g/dL; 84% vs. 70%; odds ratio (OR): 2.06, 95% confidence interval (CI): 1.07, 3.97; P=0.031] and within a shorter time frame (median 3.4 vs. 4.3 weeks). FCM treatment significantly improved vitality (P=0.025) and social functioning (P=0.049) prior to delivery. Treatment-related adverse events were experienced by 14 (FCM; 11%) and 19 (FS; 15%) women, with markedly higher rates of gastrointestinal disorders reported with FS (16 women) than with FCM (3 women). Newborn characteristics were similar across treatments. CONCLUSIONS During late-stage pregnancy, FCM may be a more appropriate option than first-line oral iron for rapid and effective anemia correction, with additional benefits for vitality and social functioning.

Abstract
Background Iron-deficiency anemia is the most common nutritional cause of anemia in pregnancy and is often responsible for puerperal anemia. Puerperal anemia can impair postpartum maternal and neonatal well-being. Objective To determine the effect of treatment of moderate puerperal iron-deficiency anemia using a single intravenous total-dose iron dextran versus daily single dose oral iron(III)-hydroxide polymaltose. Methodology A randomized controlled study in which postpartum women with moderate iron-deficiency anemia were randomized into treatment with either a single total-dose intravenous iron dextran or with daily single doses of oral iron(III)-hydroxide polymaltose tablets for 6 weeks. Effects on hemoglobin concentration using either method were compared at 6 weeks postpartum. Analysis was per protocol using SPSS version 17 for windows. P-values ≤0.05 were considered significant. Results Two hundred eighty-four women were recruited for the study: 142 women received single total dose intravenous infusion of iron dextran while 142 received daily oral iron(III)-hydroxide polymaltose tablets. Approximately 84.0% (237/282) completed the study and were analyzed including 81% (115/142) of those randomized to injectable iron therapy compared to 85.9% (122/142) of those randomized to oral treatment. The proportions of women who had attained hemoglobin concentration of at least 10 g/dL by the 6 weeks postpartum visit did not differ significantly between cases and controls (95.7% vs 94.3%; P=0.73). Similarly, the mean increases in hemoglobin following either therapeutic route were comparable (1.03±0.56 g/dL for intravenous iron and 0.97±0.46 g/dL for the oral group; P=0.42). Conclusion Single total-dose intravenous iron for treatment of puerperal iron-deficiency anemia was as effective as daily single doses of ferric iron tablets. For puerperal patients with iron-deficiency anemia in whom compliance with and tolerability of oral iron are not certain, a single total-dose intravenous iron can be safely offered.

Abstract
Objective. To evaluate safety and efficacy of intravenous ferric carboxymaltose (FCM) versus standard medical care (SMC) for iron-deficiency anemia (IDA) in postpartum women and women with heavy menstrual bleeding. Study Design. This open-label, multicenter study randomized women with IDA (hemoglobin ≤ 11.0 g/dL) to single doses of FCM (15 mg/kg [maximum 1000 mg]) or SMC (this treatment was determined by the investigator and there may have been no treatment). Safety data (primary outcome) were collected for 30 days. Results. Of 2045 subjects enrolled (FCM: n = 1023; SMC: n = 1022), 996 received FCM and 1022 received SMC. At least 1 serious adverse event (AE) was reported by 0.6% and 2.2% of subjects in the FCM and SMC groups, respectively; none were considered treatment related. The difference in serious AEs was primarily due to higher rates of uterine leiomyoma, uterine hemorrhage, and menorrhagia in SMC subjects with heavy menstrual bleeding. Common AEs were generally predictable, with higher rates of infusion site reactions in FCM subjects and gastrointestinal AEs in SMC subjects. Mean hemoglobin increases were greater in the FCM group than the SMC group. Conclusion. FCM was well tolerated and effectively increased mean hemoglobin levels in postpartum women or women with heavy menstrual bleeding and IDA. This trial is registered with ClinicalTrials.gov, NCT00548860.

Abstract
AbstractAnemia of pregnancy, an important risk factor for fetal and maternal morbidity, is considered a global health problem, affecting almost 50% of pregnant women. In this article, diagnosis and management of iron, cobalamin, and folate deficiencies, the most frequent causes of anemia in pregnancy, are discussed. Three clinical cases are considered. Iron deficiency is the most common cause. Laboratory tests defining iron deficiency, the recognition of developmental delays and cognitive abnormalities in iron-deficient neonates, and literature addressing the efficacy and safety of IV iron in pregnancy are reviewed. An algorithm is proposed to help clinicians diagnose and treat iron deficiency, recommending oral iron in the first trimester and IV iron later. Association of folate deficiency with neural tube defects and impact of fortification programs are discussed. With increased obesity and bariatric surgery rates, prevalence of cobalamin deficiency in pregnancy is rising. Low maternal cobalamin may be associated with fetal growth retardation, fetal insulin resistance, and excess adiposity. The importance of treating cobalamin deficiency in pregnancy is considered. A case of malarial anemia emphasizes the complex relationship between iron deficiency, iron treatment, and malaria infection in endemic areas; the heightened impact of combined etiologies on anemia severity is highlighted.

Abstract
BACKGROUND AND OBJECTIVES To evaluate the clinical efficacy of a single-dose intravenous infusion of iron isomaltoside compared with current treatment practice with oral iron measured by physical fatigue in women after postpartum haemorrhage. MATERIALS AND METHODS Single-centre, open-label, randomized controlled trial. Participants received intravenous iron (n = 97) or oral iron (n = 99), and completed the Multidimensional Fatigue Inventory and Edinburgh Postnatal Depression Scale, and haematological and iron parameters were measured. Primary outcome was the aggregated change in physical fatigue score from baseline to 12 weeks postpartum. RESULTS The difference in physical fatigue score was -0·97 (95% CI: -1·65; -0·28, P = 0·006) in favour of intravenous iron, but did not meet the predefined difference of 1·8. Across visits, we found statistically significant differences in fatigue and depression scores, as well as in haematological and iron parameters, all in favour of intravenous iron. There were no serious adverse reactions. CONCLUSION A single dose of intravenous iron was associated with a statistically significant reduction in aggregated physical fatigue within 12 weeks after postpartum haemorrhage compared to standard medical care with oral iron below the prespecified criteria of clinical superiority. As patient-reported outcomes improved significantly and intravenous iron resulted in a fast hematopoietic response without serious adverse reactions, intravenous iron may be a useful alternative after postpartum haemorrhage if oral iron is not absorbed or tolerated.

Abstract
AIM We compared the iron concentration in breast milk after a single high dose of intravenous iron isomaltoside or daily oral iron for postpartum haemorrhage. METHODS In this randomised controlled trial, the women were allocated a single dose of intravenous 1200 mg iron isomaltoside or oral iron at a mean daily dose of 70.5 mg. We included 65 women with sufficient breast milk three days after inclusion - 30 from the intravenous iron group and 35 from the oral iron group - and collected breast milk and maternal blood samples three days and one week after allocation. RESULTS The mean (±SD) iron concentration in breast milk in the intravenous and oral groups was 0.72 ± 0.27 and 0.40 ± 0.18 mg/L at three days (p < 0.001) and 0.47 ± 0.17 and 0.44 ± 0.25 mg/L after one week (p = 0.64). Baseline samples were not available that soon after birth. CONCLUSION A single high dose of intravenous iron isomaltoside for postpartum haemorrhage led to a transient increase in the iron concentration in breast milk three days after treatment compared with oral iron. The difference disappeared one week after treatment, and mean iron concentrations were within the normal range in all samples.

Abstract
INTRODUCTION Iron deficiency is the most common cause of Post-partum anaemia, reported as 50-60% in India. It is primarily due to inadequate iron intake and due to peripartum blood loss. It has been associated with significant post-partum complications. Therefore, Post-partum iron deficiency warrants greater attention and higher quality care. Oral iron treatment has been considered the standard of care. However, parenteral iron treatment is expected to be advantageous in cases where oral iron therapy is not possible. As a result, there is increased interest in parenteral iron therapy. Recently, a new parenteral iron preparation, Ferric Carboxy Maltose (FCM), was developed to facilitate effective treatment of Iron Deficiency Anaemia (IDA). This study was carried out in women with Post-partum IDA who were expected to benefit from the short treatment period permitted by the larger doses given parenterally. AIM To evaluate the efficacy, safety and tolerability of intra venous FCM compared to oral iron in treating Post-partum IDA patients. MATERIALS AND METHODS This was a hospital based prospective comparative study. Women with Haemoglobin (Hb) between 7-10 g/dl and peripheral smear showing microcytic hypochromic anaemia on the first Post-partum day were included in the study. These women were randomised to receive either IV FCM (single dose 1000 mg) or oral ferrous ascorbate (100 mg twice daily for 6 weeks). Statistical analysis was done by student's paired and unpaired t-test and by chi- square test and fischer-exact t-test. RESULTS Ninety patients (45 in each group) were followed at one week and six weeks from the start of treatment and their Hb were estimated. Significant rise in Hb was observed in subjects treated with FCM compared to oral iron. FCM treated subjects were more likely to achieve an Hb rise greater than or equal to 3.0 g/dL. FCM was better tolerated with complete adherence to treatment as compared to oral ferrous ascorbate. CONCLUSION FCM showed robust evidence of efficacy, tolerability and safety in comparison to oral iron. Collectively, these data support the clinical utility of FCM in treating Post-partum IDA patients.

Abstract
Background Iron deficiency is very common in a number of medical conditions. Ferric carboxymaltose is a new stable iron preparation that can be administered in single infusions over short periods of time. The aim of this study was to conduct a systematic review of randomised controlled trials (RCTs) regarding the efficacy and safety of the novel complex compared with other iron formulations. In addition, the feasibility of a network meta-analysis for indirect comparisons was investigated. Methods A systematic literature review was performed for published RCTs on the use of ferric carboxymaltose in iron deficiency between July and October 2014. Indirect comparisons were also addressed using terms referring to competing iron formulations. We further supported the qualitative results of the systematic review by a network meta-analysis that allows pooling the evidence around different intervention outcomes in the absence of trials involving a direct comparison. Results The initial search yielded 1027 citations, which was decreased to 21 studies eligible for inclusion in the review. Studies were heterogeneous in the number of patients randomised, iron deficiency-related conditions addressed, trial inclusion criteria, time horizon, treatment dosage and outcomes assessed. Six studies with the same time horizon (i.e. 6 weeks) were included in the network meta-analysis. Considering the differences between final and initial outcome values for each iron formulation, the mean difference of these differences (delta) was estimated for each couple of treatments involving ferric carboxymaltose. Significant improvements in serum ferritin (µg/l) were obtained with ferric carboxymaltose compared to oral iron (delta 172.8; 95 % CI 66.7–234.4) and in haemoglobin (g/dl) with respect to ferric gluconate (delta 0.6; 95 % CI 0.2–0.9), oral iron (delta 0.8; 95 % CI 0.6–0.9) and placebo (delta 2.1; 95 % CI 1.2–3.0). Conclusions All currently available intravenous iron preparations appear to be safe and effective, but ferric carboxymaltose seems to provide a better and quicker correction of haemoglobin and serum ferritin levels in iron-deficient patients.

Abstract
BACKGROUND Pre-operative anaemia is common and occurs in up to 76% of patients. It is associated with increased peri-operative allogeneic blood transfusions, longer hospital lengths of stay and increased morbidity and mortality. Iron deficiency is one of the most common causes of this anaemia. Oral iron therapy has traditionally been used to treat anaemia but newer, safer parenteral iron preparations have been shown to be more effective in other conditions such as inflammatory bowel disease, chronic heart failure and post-partum haemorrhage. A limited number of studies look at iron therapy for the treatment of pre-operative anaemia. The aim of this Cochrane review is to summarise the evidence for use of iron supplementation, both enteral and parenteral, for the management of pre-operative anaemia. OBJECTIVES The objective of this review is to evaluate the effects of pre-operative iron therapy (enteral or parenteral) in reducing the need for allogeneic blood transfusions in anaemic patients undergoing surgery. SEARCH METHODS We ran the search on 25 March 2015. We searched the Cochrane Injuries Group's Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library), Ovid MEDLINE(R), Ovid MEDLINE(R) In-Process & Other Non-Indexed Citations, Ovid MEDLINE(R) Daily and Ovid OLDMEDLINE(R), EMBASE Classic and EMBASE (Ovid), CINAHL Plus (EBSCO), PubMed, clinical trials registries, conference abstracts, and we screened reference lists. SELECTION CRITERIA We included all randomised controlled trials (RCTs) which compared pre-operative iron monotherapy to placebo, no treatment, standard of care or another form of iron therapy for anaemic adults undergoing surgery. Anaemia was defined by haemoglobin values less than 13 g/dL for males and 12 g/dL for non-pregnant females. DATA COLLECTION AND ANALYSIS Data were collected by two authors on the proportion of patients who receive a blood transfusion, amount of blood transfused per patient (units) and haemoglobin measured as continuous variables at pre-determined time-points: pre-treatment, pre-operatively but post-treatment, and post-operatively. Statistical analysis was performed using the Cochrane statistical software, Review Manager 2014. Outcome data were summarised in tables and a forest plot. MAIN RESULTS Three prospective randomised controlled studies evaluated pre-operative iron therapy to correct anaemia (two in colorectal and one in gynaecological surgery) and included 114 patients in total. One compared oral iron versus standard care (Lidder 2007); one intravenous iron versus control (Edwards 2009); and one study compared oral versus intravenous iron (Kim 2009). Both colorectal trials reported the primary outcome (proportion of patients who received allogeneic blood transfusions) and meta-analysis showed a reduction in blood transfusions with the administration of iron therapy, but the reduction was not statistically significant (risk ratio (RR) 0.56, 95% confidence interval (CI) 0.27 to 1.18). All studies reported haemoglobin change but data for the anaemic patients were only available for two studies (Edwards 2009 and Kim 2009). Edwards 2009 showed no difference in haemoglobin at the end of treatment pre-operatively. The intravenous versus oral iron study showed an increase in haemoglobin with intravenous iron at the end of treatment pre-operatively (MD 1.90 g/dL, 95% CI 1.16 to 2.64; participants = 56), but the results are at high risk of bias because participants with less than 80% compliance with therapy were excluded from the analysis and compliance was lower in the oral iron group due to the side-effects of treatment (Kim 2009).None of the studies reported quality of life, short- or long-term mortality or post-operative morbidity. AUTHORS' CONCLUSIONS The use of iron therapy for pre-operative anaemia does not show a statistically significant reduction in the proportion of patients who received an allogeneic blood transfusion compared to no iron therapy. However, the 38 patients in our analysis falls far short of the 819 patients our information size calculation recommended to detect a 30% reduction in blood transfusions. Intravenous iron may be more effective than oral iron at increasing haemoglobin. However, all these conclusions are drawn from only three small randomised controlled studies. Further well designed, adequately powered randomised controlled studies are required to determine the true effectiveness of iron therapy for pre-operative anaemia.

Safety and Efficacy of Ferric Carboxymaltose in Anemic Pregnant Women: A Retrospective Case Control Study. Obstet Gynecol Int 2015; 2015:728952. [PMID: 26688686 PMCID: PMC4672138 DOI: 10.1155/2015/728952] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2015] [Revised: 11/08/2015] [Accepted: 11/10/2015] [Indexed: 12/21/2022] Open
Abstract
Background. Anemia during pregnancy is commonly caused by iron deficiency and can have severe consequences for both the mother and the developing fetus. The aim of this retrospective study was to assess the safety and efficacy of intravenous ferric carboxymaltose (FCM) in pregnant women. Methods. All women treated with FCM for anemia during pregnancy between 2010 and 2012 at our institution were included. A matched control group was selected, including women who either were nonanemic or had anemia but were not considered for intravenous iron. Main outcome measures were maternal safety and pregnancy outcomes. Results. The study included 128 patients (FCM: 64; control: 64). Median FCM dose was 1000 mg and median gestational age at the time of first treatment was 34 weeks and 6 days. Median Hb increased from 8.4 g/dL (interquartile range 7.7; 8.9 g/dL) at the first FCM administration to 10.7 g/dL (9.8; 11.5 g/dL; n = 46 with available Hb at delivery) at the time of delivery, achieving levels similar to those in the control group (10.8 g/dL [9.8; 11.8 g/dL; n = 48]). No treatment-related adverse events were reported and no statistically significant differences in pregnancy outcomes were observed between groups. Conclusions. Within the limitations of this case control study, FCM was a safe and efficient treatment of anemia during pregnancy.

Abstract
According to the World Health Organization (WHO), anemia is the most common disease, affecting >1.5 billion people worldwide. Furthermore, iron deficiency anemia (IDA) accounts for 50% of cases of anemia. IDA is common during pregnancy and the postpartum period, and can lead to serious maternal and fetal complications. The aim of this report was to present the experiences of a multidisciplinary expert group, and to establish reference guidelines for the optimal diagnosis and treatment of IDA during pregnancy and the postpartum period. Studies and guidelines on the diagnosis and treatment of IDA published in Turkish and international journals were reviewed. Conclusive recommendations were made by an expert panel aiming for a scientific consensus. Measurement of serum ferritin has the highest sensitivity and specificity for diagnosis of IDA unless there is a concurrent inflammatory condition. The lower threshold value for hemoglobin (Hb) in pregnant women is <11 g/dL during the 1st and 3rd trimesters, and <10.5 g/dL during the 2nd trimester. In postpartum period a Hb concentration <10 g/dL indicates clinically significant anemia. Oral iron therapy is given as the first-line treatment for IDA. Although current data are limited, intravenous (IV) iron therapy is an alternative therapeutic option in patients who do not respond to oral iron therapy, have adverse reactions, do not comply with oral iron treatment, have a very low Hb concentration, and require rapid iron repletion. IV iron preparations can be safely used for the treatment of IDA during pregnancy and the postpartum period, and are more beneficial than oral iron preparations in specific indications.

Abstract
Iron deficiency is more common in women due to uterine bleeding, which affects them throughout their fertile life. Additionally, iron needs increase physiologically during pregnancy and breastfeeding. Pregnant women therefore constitute one of the risk groups for iron deficiency. During the postpartum period, iron deficiency is the most common cause of anemia. Longer hospital stays and greater susceptibility to infections are potential consequences of postpartum anemia.

Abstract
BACKGROUND Postpartum iron deficiency anaemia is caused by bleeding or inadequate dietary iron intake/uptake. This condition is defined by iron deficiency accompanied by a lower than normal blood haemoglobin concentration, although this can be affected by factors other than anaemia and must be interpreted in the light of any concurrent symptoms. Symptoms include fatigue, breathlessness, and dizziness. Treatment options include oral or intravenous iron, erythropoietin which stimulates red blood cell production, and substitution by red blood cell transfusion. OBJECTIVES To assess the efficacy and harms of the available treatment modalities for women with postpartum iron deficiency anaemia. SEARCH METHODS The Cochrane Pregnancy and Childbirth Group's Trials Register (9 April 2015); the WHO International Clinical Trials Registry Portal (ICTRP), and the Latin-American and Caribbean Health Sciences Literature database (LILACS) (8 April 2015) and reference lists of retrieved studies. SELECTION CRITERIA We included published, unpublished and ongoing randomised controlled trials that compared a treatment for postpartum iron deficiency anaemia with placebo, no treatment, or another treatment for postpartum iron deficiency anaemia, including trials described in abstracts only. Cluster-randomised trials were eligible for inclusion. We included both open-label trials and blinded trials, regardless of who was blinded. The participants were women with a postpartum haemoglobin of 120 g per litre (g/L) or less, for which treatment was initiated within six weeks after childbirth.Non-randomised trials, quasi-randomised trials and trials using a cross-over design were excluded. DATA COLLECTION AND ANALYSIS Two review authors independently assessed studies for inclusion, quality, and extracted data. We contacted study authors and pharmaceutical companies for additional information. MAIN RESULTS We included 22 randomised controlled trials (2858 women), most of which had high risk of bias in several domains. We performed 13 comparisons. Many comparisons are based on a small number of studies with small sample sizes. No analysis of our primary outcomes contained more than two studies.Intravenous iron was compared to oral iron in 10 studies (1553 women). Fatigue was reported in two studies and improved significantly favouring the intravenously treated group in one of the studies. Other anaemia symptoms were not reported. One woman died from cardiomyopathy (risk ratio (RR) 2.95; 95% confidence interval (CI) 0.12 to 71.96; two studies; one event; 374 women; low quality evidence). One woman developed arrhythmia. Both cardiac complications occurred in the intravenously treated group. Allergic reactions occurred in three women treated with intravenous iron, not statistically significant (average RR 2.78; 95% CI 0.31 to 24.92; eight studies; 1454 women; I² = 0%; low quality evidence). Gastrointestinal events were less frequent in the intravenously treated group (average RR 0.31; 95% CI 0.20 to 0.47; eight studies; 169 events; 1307 women; I² = 0%; very low quality evidence).One study evaluated red blood cell transfusion versus non-intervention. General fatigue improved significantly more in the transfusion group at three days (MD -0.80; 95% CI -1.53 to -0.07; women 388; low quality evidence), but no difference between groups was seen at six weeks. Maternal mortality was not reported.The remaining comparisons evaluated oral iron (with or without other food substances) versus placebo (three studies), intravenous iron with oral iron versus oral iron (two studies) and erythropoietin (alone or combined with iron) versus placebo or iron (seven studies). These studies did not investigate fatigue. Maternal mortality was rarely reported. AUTHORS' CONCLUSIONS The body of evidence did not allow us to reach a clear conclusion regarding the efficacy of the interventions on postpartum iron deficiency anaemia. The quality of evidence was low.Clinical outcomes were rarely reported. Laboratory values may not be reliable indicators for efficacy, as they do not always correlate with clinical treatment effects. It remains unclear which treatment modality is most effective in alleviating symptoms of postpartum anaemia.Intravenous iron was superior regarding gastrointestinal harms, however anaphylaxis and cardiac events occurred and more data are needed to establish whether this was caused by intravenous iron.The clinical significance of some temporarily improved fatigue scores in women treated with blood transfusion is uncertain and this modest effect should be balanced against known risks, e.g. maternal mortality (not reported) and maternal immunological sensitisation, which can potentially harm future pregnancies.When comparing oral iron to placebo it remains unknown whether efficacy (relief of anaemia symptoms) outweighs the documented gastrointestinal harms.We could not draw conclusions regarding erythropoietin treatment due to lack of evidence.Further research should evaluate treatment effect through clinical outcomes, i.e. presence and severity of anaemia symptoms balanced against harms, i.e. survival and severe morbidity.

Abstract
This article considers the use and modality of iron therapy to treat iron deficiency in patients with heart failure, an aspect of care which has received relatively little attention compared with the wider topic of anaemia management. Iron deficiency affects up to 50% of heart failure patients, and is associated with poor quality of life, impaired exercise tolerance, and mortality independent of haematopoietic effects in this patient population. The European Society of Cardiology Guidelines for heart failure 2012 recommend a diagnostic work-up for iron deficiency in patients with suspected heart failure. Iron absorption from oral iron preparations is generally poor, with slow and often inefficient iron repletion; moreover, up to 60% of patients experience gastrointestinal side effects. These problems may be exacerbated in heart failure due to decreased gastrointestinal absorption and poor compliance due to pill burden. Evidence for clinical benefits using oral iron is lacking. I.v. iron sucrose has consistently been shown to improve exercise capacity, cardiac function, symptom severity, and quality of life. Similar findings were observed recently for i.v. ferric carboxymaltose in patients with systolic heart failure and impaired LVEF in the double-blind, placebo-controlled FAIR-HF and CONFIRM-HF trials. I.v. iron therapy may be better tolerated than oral iron, although confirmation in longer clinical trials is awaited. Routine diagnosis and management of iron deficiency in patients with symptomatic heart failure regardless of anaemia status is advisable, and, based on current evidence, prompt intervention using i.v. iron therapy should now be considered.

Abstract
Background The tolerability of oral iron supplementation for the treatment of iron deficiency anemia is disputed. Objective Our aim was to quantify the odds of GI side-effects in adults related to current gold standard oral iron therapy, namely ferrous sulfate. Methods Systematic review and meta-analysis of randomized controlled trials (RCTs) evaluating GI side-effects that included ferrous sulfate and a comparator that was either placebo or intravenous (IV) iron. Random effects meta-analysis modelling was undertaken and study heterogeneity was summarised using I2 statistics. Results Forty three trials comprising 6831 adult participants were included. Twenty trials (n = 3168) had a placebo arm and twenty three trials (n = 3663) had an active comparator arm of IV iron. Ferrous sulfate supplementation significantly increased risk of GI side-effects versus placebo with an odds ratio (OR) of 2.32 [95% CI 1.74–3.08, p<0.0001, I2 = 53.6%] and versus IV iron with an OR of 3.05 [95% CI 2.07-4.48, p<0.0001, I2 = 41.6%]. Subgroup analysis in IBD patients showed a similar effect versus IV iron (OR = 3.14, 95% CI 1.34-7.36, p = 0.008, I2 = 0%). Likewise, subgroup analysis of pooled data from 7 RCTs in pregnant women (n = 1028) showed a statistically significant increased risk of GI side-effects for ferrous sulfate although there was marked heterogeneity in the data (OR = 3.33, 95% CI 1.19-9.28, p = 0.02, I2 = 66.1%). Meta-regression did not provide significant evidence of an association between the study OR and the iron dose. Conclusions Our meta-analysis confirms that ferrous sulfate is associated with a significant increase in gastrointestinal-specific side-effects but does not find a relationship with dose.
