Abstract Introduction Perioperative anemia commonly occurs in patients undoing major surgery. We aimed to assess the efficacy and safety of intravenous iron therapy (IVIT) given compared to standard practice of oral iron in the perioperative period. Design The search strategy was conducted in Medline, Embase, and Cochrane for only eligible clinical trials (randomized controlled trials) comparing IV over oral iron therapy up to July 2019. The primary outcome was the effect of IVIT on the change of hemoglobin level. The secondary outcomes were the effects of IVIT compared to oral iron on ferritin level, mean corpuscular volume, and adverse side effects. Data were collected from each trial and where applicable meta-analyzed using RevMan. Results Six randomized clinical trials that fit our inclusion criteria were included in the study.We found that IVIT increases the level of hemoglobin compared to oral iron (MD: Mean difference 0.90, 95% confidence interval [CI]: 0.44–1.36, P = 0.000). Serum ferritin levels increased significantly in favor of the IV iron group compared to the oral iron group at posttreatment (MD: 106.95, 95% CI: 73.29, 140.62 ng/mL). In addition, marked increases in the pooled mean corpuscular volume (MCV) level were observed in favor of the IVIT (MD: 6.07, 95% CI: −0.88–13.02). There was no significant difference in the rate of adverse effects in both the groups. Conclusions IV iron therapy is more effective than oral iron on increasing hemoglobin, ferritin, and MCV in the perioperative period and is also as safe with no diffidence in the risk of developing adverse side effects.

Background: IV administration of iron is appropriate for the treatment of iron deficiency anemia (IDA) when orally administered iron has not been effective, tolerated, or clinically appropriate. In Calgary, Alberta, high levels of IV iron utilization required review, because of significant health care resource utilization, high cost, and reduced accessibility. Objectives: The primary objective was to describe the population of adult patients in Calgary with estimated glomerular filtration rate greater than or equal to 30 mL/min/1.73 m2 for whom IV iron was dispensed from acute care facilities, in terms of pretreatment laboratory data, previous use of oral iron, and treatment location, as well as to characterize dose and product selection for IV iron. The secondary objective was to determine the proportion of inpatients whose treatment was in alignment with the Toward Optimized Practice clinical practice guideline for IDA. Methods: A retrospective review of electronic charts was used to obtain data about patients with a first dose of IV iron dispensed in Calgary hospitals between March 1 and December 31, 2018. The data were analyzed descriptively. Results: A total of 1352 patients met the inclusion criteria. These patients received a total of 3532 doses of IV iron, 97.1% of which were iron sucrose, at a median of 300 mg per infusion. Laboratory indices assessed before the first infusion were hemoglobin (mean 92, standard deviation [SD] 19.6 g/L), mean corpuscular volume (mean 81 [SD 10.3] fL), and ferritin (median 18 [interquartile range 9–48] μg/L). Among the included patients, 233 (17.2%) had oral iron dispensed within 90 days before their first IV dose of iron. Only 146 (20.1%) of the 726 inpatients had treatment that was in alignment with the Toward Optimized Practice IDA guideline. Conclusions: There was substantial variation in baseline hemoglobin, mean corpuscular volume, and ferritin, and in the use of oral iron before initiation of IV iron treatment. Provision of educational tools and stewardship initiatives may help in ensuring alignment of iron prescribing with current guidelines. RÉSUMÉ Contexte : L’administration de fer par intraveineuse (IV) convient au traitement de l’anémie ferriprive lorsque son administration par voie orale n’a pas été efficace, tolérée ou appropriée d’un point de vue clinique. À Calgary (Alberta), il a fallu réviser les quantités de fer administrées par IV en raison de la mobilisation importante des ressources de soins de santé et des coûts élevés que cela exigeait ainsi que de l’accessibilité réduite au produit. Objectifs : L’objectif principal consistait à décrire la population de patients adultes, dont le taux estimé de filtration glomérulaire était supérieur ou égal à 30 mL/min/1,73 m2 et à qui on administrait du fer par IV dans des installations de soins intensifs de Calgary. La description devait se faire en termes de données de laboratoire préalables au traitement, d’administration antérieure de fer par voie orale et de lieu du traitement; il s’agissait aussi de décrire la dose et la sélection du produit pour l’administration de fer par IV. L’objectif secondaire consistait à déterminer la proportion de patients hospitalisés, dont le traitement s’alignait sur les directives de pratique clinique Toward Optimized Practice relatives à l’anémie ferriprive. Méthodes : Un examen rétrospectif des tableaux électroniques a permis d’obtenir des données sur les patients, ayant reçu une première dose de fer par IV dans les hôpitaux de Calgary, entre le 1er mars et le 31 décembre 2018. Les données ont fait l’objet d’une analyse descriptive. Résultats : Au total, 1352 patients répondaient au critère d’inclusion. Ils ont reçu 3532 doses de fer par IV, dont 97,1 % de saccharose de fer à raison d’une médiane de 300 mg par perfusion. Les indices de laboratoire évalués avant la première perfusion concernaient l’hémoglobine (moyenne 92, écart-type [ET] 19,6 g/L), le volume corpusculaire moyen (moyenne 81 [ET 10,3] fL) et la ferritine (moyenne 18 [écart interquartile 9-48] μg/L). Parmi les patients de l’étude, 233 (17,2 %) avaient reçu du fer par voie orale 90 jours avant la première dose de fer administrée par IV. Seuls 146 (20,1 %) des 726 patients hospitalisés avaient reçu un traitement conforme aux directives de pratique clinique Toward Optimized Practice relatives à l’anémie ferriprive. Conclusions : On a constaté une variation importante de l’hémoglobine de base, du volume corpusculaire moyen et de la ferritine, ainsi que de l’utilisation du fer par voie orale avant le début du traitement par IV. Des outils pédagogiques et des initiatives de gestion pourraient aider à assurer l’alignement de la prescription de fer sur les directives actuelles.

ABSTRACT Iron deficiency is a major worldwide health problem. There is recent evidence that anemia is the last manifestation of the syndrome. Advances in outlining the physiology of iron deficiency have been made; gaps remain in the current understanding. While oral iron supplement remains the mainstay, some indications for intravenous (IV) administration have developed. In this review, we will highlight the indications and prerequisites of IV iron therapy, dosage, safety, and method of administration. How to cite this article Gautham KSK. Intravenous Iron Sucrose.

Introduction: Anemia is the commonest major contributing factor in maternal mortality and morbidity in developing countries and according to World Health Organization (WHO) criteria, it contributes to 20% of maternal deaths. Anemia in pregnancy defined as hemoglobin level <11 gm/dl (7.45 mmol/L) and hematocrit less than 33% (WHO). Aim: To compare the efficacy of oral iron ferrous sulphate therapy with intravenous iron sucrose therapy in the treatment of iron deficiency anemia during postpartum period. Material & Methods: This was a prospective randomized comparative clinical trial single center study conducted on 200 postpartum women aged >18 years (after normal delivery or LSCS) within 10 days of delivery with Hb level more or equal to 6 gm/dl but less than 10 gm/dl were included in the study. This was a one year study conducted during 1st December 2018 to 30th November 2019. Results : There was a significant increase in the hemoglobin level in both the groups i.e. in IV iron group, from 8.26 ±1.03gm/dl on day 1 to 11.62±0.94gm/dl on day 45 as compared to oral iron group, from 8.24±1.09gm/dl on day 1 to 11.07±1.14gm/dl on day 45; and serum ferritin level from 41.69±40.45ng/ml on day 1 to 77.34±41.60ng/ml on day 45 in IV iron group as compared to the oral iron group from 22.20±8.82ng/ml on day 1 to 31.72±9.72 ng/ml on day 45. So, there was a rapid increase in both hemoglobin and serum ferritin levels in IV iron group as compared to the oral iron group. Conclusion: Intravenous iron sucrose administration increases the hemoglobin level and serum ferritin more rapidly in compare to the oral intake of ferrous sulphate in women with iron deficiency anemia in postpartum women in our study. Keywords: Iron deficiency anemia, Intravenous iron sucrose, Serum ferritin, Maternal mortality.

Background: In India, women become pregnant with low baseline hemoglobin level resulting in high incidence of moderate to severe anemia in pregnancy where oral iron therapy cannot meet the requirement. Pregnant women with moderate anemia are to be treated with parenteral iron therapy. The aim of the study is to the infusion of intravenous iron sucrose and its outcome in the management of anemia.Methods: Totally 100 pregnant females were included in the study. The study period was from January 2018-July 2018 at vanavil medical center in Chennai. 50 Patients of Group A was given oral iron tablets containing100mg of elemental iron. 50 patients of Group B was given a total of 1000 mg of intravenous iron sucrose divided into five doses of 200 mg each at weekly intervals. Estimation of hemoglobin was started 4 weeks after commencement of iron therapy and then repeated every 4 weeks till 36 weeks of gestation, pre-delivery and postpartum.Results: Target hemoglobin levels were achieved in 4 weeks’ time in 19 (76%) patients in the iron sucrose group as compared to 08 (32%) of patients in the oral iron group. There was a significant improvement in the various hematological parameters in iv sucrose group as compared to patients in the oral iron group. There were no significant allergic reactions in iv sucrose group.Conclusions: Our results showed that intravenous iron sucrose therapy was effective to treat moderate anemia in pregnant women. Intramuscular preparations are known to be associated with local side-effects. Iron sucrose complex iv therapy was with negligible side effects. It caused a rapid rise in hemoglobin level and the replacement of stores was faster. Long term comparative studies are required to assess if they can be used at a peripheral level.

Introduction: Anemia is the most common finding in chronic kidney disease patients. Iron supplements are commonly prescribed for these patients with or without erythropoietin therapy by means of oral and intravenous iron. Both oral and intravenous irons have their own advantage and disadvantage, and the efficacy is also different. The objective of the study is to analyze the efficacy of oral and intravenous iron in chronic kidney disease patients on erythropoietin therapy, an erythropoiesis stimulating agents for increment of haemoglobin. Methods: This is a prospective study comparing intravenous iron to oral iron in chronic kidney disease patients who underwent maintenance hemodialysis at different centers and visited Kathmandu Medical College Teaching Hospital from April 2010 to April 2011. Patients having a haemoglobin level of < 11 g/dl, transferrin saturation (TSAT) < 25%, ferritin < 300ng/ml and who were on erythropoietin therapy were allocated alternately into two groups to receive oral iron (iron fumarate) or IV iron (iv sucrose). Haemoglobin was measured after 30 days of therapy. Results: A significant increase in haemoglobin levels was observed in both groups. But the mean haemoglobin increment was more in the IV iron group than in the oral iron group. Sixty percent 60% of patients in the IV iron group had an increase in the haemoglobin level of more than 1gm/dl while only 20% of the oral iron group had this increase. Conclusions: Intravenous iron therapy is more effective in raising the hemoglobin level in hemodialysis dependent chronic kidney disease patients. Keywords: anemia; chronic kidney disease; iron.

Abstract Background: Prior studies have indicated that transfusion is unusual (2%) in pregnant women with iron deficiency anemia. Nonetheless, compliance with oral iron replacement can be an issue and physicians may wish to use IV iron therapy in markedly anemic pregnant women. Objectives: to evaluate the effectiveness of adding intravenous iron sucrose concentrate (ISC) to pregnant patients already taking oral iron in terms of effect on hemoglobin, effect on ferritin levels, rates of transfusion, and cost. Methods: We analyzed all referrals from Obstetrics to Hematology clinic and Obstetrics consultation (Internal medicine) clinic from January 2014 to June 2016. Of the 176 pregnant patients, 98 were referred for anemia, including 81 patients with Hgb < 12 g/dl and ferritin < 20 ug/L. All had previously been given oral ferrous sulfate prescriptions. Patients with hemoglobinopathy were excluded. All 81 patients were advised to continue on the oral iron, and 40 were given IV iron sucrose (ISC group). Results: The average cumulative dose of iron sucrose was 700 mg, a mean of 5.575 doses (initiated in the third trimester in 38 of 40 patients). The lowest antepartum Hgb was 8.18 g/dl in the ISC group and 9.58 in the oral only group; there was an average Hgb increase of 2.17 vs 1.76 g/dl respectively (p=.107 NS and the 0.41 g/dl difference was considered to be of no clinical consequence). 89% in the ISC group vs 30% in the oral achieved a ferritin >20 (p=0.000015). No adverse events in the IV iron group were reported. There was 1 transfusion in the oral iron group attributable to iron deficiency (2.4%) vs none in the IV iron group (p = 0.107 NS). Two patients were transfused in the antenatal period before IV iron was started and 1 transfused because of post-partum hemorrhage. The total cost of the IV iron therapy would add an average of $1,500 per patient. Thus, and additional cost of $60,000 in IV iron would be required to prevent 1 transfusion [40:1]. Conclusions: ISC corrects ferritin in more patients than oral iron replacement, but did not significantly increase Hgb levels or have a meaningful impact on the transfusion rate. The additional cost and lack of clinically improved outcomes with IV iron argue against its use and in favor of strategies to ensure compliance with oral iron. Disclosures No relevant conflicts of interest to declare.

Background: Iron deficiency anaemia (IDA) continues to be a very common problem in developing countries leading to a spectrum of adverse events in pregnant women. The objective of this study was to determine the efficacy, side effects and tolerance of ferric carboxymaltose as compared to available iron preparations for the prophylaxis and treatment of mild to moderate iron deficiency anaemia during pregnancy.Methods: One-year clinical study (from June 2017 to May 2018). A total 100 patients were enrolled after matching inclusion and exclusion criteria. The efficacy assessment was performed during 4, 8, and 12 weeks of starting therapy. If the patient is not responding to therapy in either arm as documented by no rise or fall in haemoglobin levels patients may be removed from study for other therapy. Treatment duration up to 12 weeks. Safety and efficacy follow-up visit at 4, 8 and 12 weeks. Institutional ethics committee permission was taken.Results: On intra-group comparisons there was significant increase in haemoglobin levels at 8 and 12 weeks in oral iron group as compared to day 1 haemoglobin levels while there was significant increase in haemoglobin levels at 4, 8 and 12 weeks in IV iron group as compared to day 1 haemoglobin levels. On intergroup comparisons between oral and IV iron group, there was significant increase in haemoglobin levels at 4, 8 and 12 weeks in IV iron group as compared oral iron group haemoglobin levels.Conclusions: Intravenous iron therapy with ferric carboxymaltose causes significant improvement in haemoglobin more quickly and more effective in correcting iron deficiency anaemia in pregnancy compared to oral treatment in terms of increase in haemoglobin levels at 4, 8 and 12 weeks. Intravenous ferric carboxymaltose is safe and effective option for pregnant women with iron deficiency anaemia.

Abstract To date, limited data is available regarding prevalence of iron deficiency during pregnancy in Australia. There is little if any data currently available regarding comparative efficacy of IV iron versus oral iron therapy in pregnant women. In Australia the prevalence of iron deficiency anaemia (IDA) is approximately 5% in the general population with higher rates in pregnant women. At a single site, the Launceston General Hospital (LGH), we prospectively investigated 200 pregnant women between January and July 2007 with FBC and iron studies at the first or second antenatal visit. Among those, 40 women (20%) had iron deficiency anaemia, and were recruited to a prospective randomised trial to determine whether intravenous iron therapy (iron polymaltose) is superior to oral iron (ferrous sulphate) for the management of IDA associated with pregnancy. The patients’ median age was 28 years old (range; 19–40) with a median gestational age at recruitment of 27 weeks (range; 13–29) and a median body weight of 74 kg (range; 47–130). At recruitment median Hb was 106 g/L (range; 90–114, normal range; 120–160 g/L), while median serum ferritin was 11.5 μg/L and mean ferritin was 19 μg/L normal range; 30–460). After four weeks of treatment the Hb level increased by a mean of 6g/L on oral iron and by 10.5 g/L after IV iron. Mean/Median serum ferritin did not increase significantly in women on oral iron, but increased to a median of 96.5 μg/L and a mean of 224 μg/L in those received IV iron. Multi-variate analysis using general linear modelling for continuous variables showed a significant increase in serum ferritin after treatment with IV iron versus oral iron (p=0.017). There was no statistically significant difference in terms of Hb increment, patients’ parity, weight, and date of last pregnancy between groups. Analysis of quality of life questionnaires to assess patients’ well-being, ability to perform activities, and symptoms of anaemia showed improvement in both groups of patients with a trend to greater and faster improvement after IV iron. Both treatments were well tolerated without major side effects. The preliminary data indicate IDA is a common finding during pregnancy in the LGH population, and intravenous iron therapy appears a safe and effective treatment in this cohort of patients. This research received a grant from the Clifford Craig Medical Research Trust, Tasmania, Australia.

Background: The aim of this study was to compare the efficacy and safety of iron sucrose with oral iron in the treatment of iron deficiency anemia of pregnancy.Methods: An interventional comparative study was conducted at Jhalawar Medical College, Jhalawar involving 80 pregnant women with iron deficiency anemia from March 2016 to August 2016. Inclusion criteria were gestational age between 24-32 weeks with established iron deficiency anemia, with hemoglobin between 7-10g/dl. Target Hemoglobin was 11 g/dl. In intravenous iron sucrose group iron sucrose dose was calculated from following formula: total iron dose required (mg) = 2.4 x body weight in Kg x (target Hb – Patient’s Hb g/dl) + 500. In oral iron, group patient received ferrous-sulphate 335 mg daily BD. Hb level were reviewed at 2, 4, 6 weeks.Results: Change in Hemoglobin level from baseline significantly higher in IV iron group than oral iron group. In IV iron, group mean value of baseline Hb was 8.07±0.610 g/dl and in oral iron group was 8.48±0.741 g/dl. At the end of 6-week mean hemoglobin in IV iron sucrose was 10.66±0.743 g/dl and in oral iron group was 10.08±0.860 g/dl.Conclusions: Intravenous iron sucrose elevates more Hb than oral iron, with less adverse effects.
