Background: Low dose (200 mg) extended Intravenous iron sucrose remains the most common treatment option in patients who are intolerant to oral iron therapy in patients with Iron deficiency anemia (IDA). The objective of this study was to evaluate the efficacy and safety of high dose accelerated intravenous iron sucrose (IS) in the treatment of adults with iron deficiency anemiaMethods: One hundred adult patients with iron deficiency anemia, who had intolerance or showed no effect with oral iron therapy, received daily doses of 500 mg of intravenous iron sucrose until the hemoglobin level was corrected or until receiving the total dose of intravenous iron calculated for each patient.Results: The mean and median Hb (g/dL) 6.47±1.656 and 6.6 (2) at baseline, 9.61±1.629 and 9.6 (2) at 2 weeks of treatment, 11.85±1.277 and 12 (1) at 4 weeks of treatment respectively. The mean rise of Hb was 3.13±1.41 and 5.37±1.50 after 2 and 4 weeks of treatment respectively (p<0.000). A total of 303 intravenous infusions of iron sucrose were administered and iron sucrose was generally well tolerated with twenty-six patients developing mild and one patient developing moderate adverse drug reactions. There was no serious adverse event recorded.Conclusions: Accelerated high dose intravenous iron sucrose is a safe and cost effective option minimizing frequent hospital visits in the treatment of adults with iron deficiency anemia who are intolerant or lack satisfactory response to oral iron therapy.

Abstract Abstract 484 Background Treatment options for individuals diagnosed with iron deficiency anemia (IDA) include oral or intravenous iron. Oral iron may not increase patient hemoglobin levels adequately, due to poor compliance and/or suboptimal gastrointestinal absorption due to inflammation-mediated induction of hepcidin, which regulates iron homeostasis. This study evaluated whether hepcidin levels can be used to identify patients with IDA who are unresponsive to oral iron therapy. Methods Hepcidin levels were assessed in a subset of subjects enrolled in a randomized trial comparing oral iron (ferrous sulfate) to intravenous iron (Injectafer®[ferric carboxymaltose, FCM]) in subjects with IDA (Hemoglobin [Hb] ≤ 11 g/dL; and ferritin ≤ 100 ng/mL, or ≤ 300 ng/mL when transferrin saturation (TSAT) was ≤ 30%) (Szczech et al Amer Soc Nephrol 2011; 22:405A). Subjects who met the inclusion criteria underwent a 14-day (run-in) course of ferrous sulfate 325 mg, three times per day. Subjects with an increase in Hb ≥ 1 g/dL were considered to be “responders” and not randomized. “Non-responders” were randomized to ferric carboxymaltose (2 injections of 750 mg given on Day 0 [day of randomization] and Day 7) or oral iron for 14 more days. Hb levels and markers of iron status were assessed at screening (day-15), day-1 and day 35. Hepcidin levels were analyzed at screening (Day -15) in an initial Cohort (I) of 44 patients, 22 responders and 22 non-responders. A hepcidin value of >20 ng/mL was identified for further analysis for predictive values for non-responsiveness to 14 day oral iron run-in in 240 patients (Cohort II). Hepcidin levels were also analyzed at Day -1 and Day 35 in a Cohort (III) of patients who were then randomized to FCM vs. oral iron therapy. Results Hepcidin screening levels in Cohort I were significantly higher in the non-responders vs. responders (33.2 vs. 8.7 ng/mL, p < 0.004). Twenty one of 22 non-responders had hepcidin values > 20 ng/mL. For Cohort II, mean hepcidin levels were again significantly higher in the non-responders vs. responders (38.4 vs. 11.3 ng/mL, p = 0.0002). Utilizing a hepcidin criterion of > 20 ng/mL, we found a sensitivity of 41.3% (26 of 150), specificity of 84.4% (76 of 90), and a positive predictive value (PPV) of 81.6% (62 of 76) for non-responsiveness to oral iron (Figure: The Receiver Operator Characteristic curves present plots of sensitivity vs. (1-specificity) for hepcidin, ferritin, and TSAT at the various cutoff levels indicated near the respective curves in the same color as the respective curves). While ferritin < 30ng/mL or TSAT <15% had greater sensitivity (77.3% and 64.7%, respectively), their PPVs (59.2% and 55%) were inferior to PPVs for hepcidin. Patients subsequently randomized to FCM vs. oral iron responded with Hgb increases of ≥1 g/dL for 65.3% vs. 20.8% (p <0.0001)and mean Hgb increases of 1.7 ± 1.3 vs. 0.6 ± 0.9 g/dL (p = 0.0025), respectively. Conclusion Our analysis provides evidence that non-responsiveness to oral iron in patients with iron deficiency anemia can be predicted from patients' baseline hepcidin levels, which have superior positive predictive values compared to transferrin saturation or ferritin levels. Furthermore, non-response to oral iron therapy does not rule out iron deficiency, since two thirds of these non-responders to oral iron responded to IV iron.

Intravenous Iron Therapy

Iron replacement for iron-deficiency anemia has historically been accomplished with the use of oral iron therapy. Although oral iron is appropriate for most iron-deficiency anemia patients, many patients do not respond to or may be intolerant of oral iron, or may experience bleeding of sufficient magnitude to require higher iron doses than that achievable with oral iron. Intravenous iron therapy is a useful option for these latter patients. Three intravenous iron products are recommended: low-molecular weight iron dextran (INFeD), ferric gluconate (Ferrlecit), and iron sucrose (Venofer). These intravenous iron products have superior safety profiles compared to high-molecular weight iron dextran. The Food and Drug Administration's approval of erythropoietic-stimulating agents to treat certain types of anemia has increased usage of intravenous iron for functional iron deficiency. This review summarizes the current status of intravenous iron products and discusses their advantages and disadvantages in treating both absolute and functional iron deficiency.

Serum Hepcidin

Greater prevalence of iron deficiency (ID) has been observed in overweight and obese children and adolescents. Hepcidin acts as a key regulator of iron metabolism. Hepcidin synthesis increases in response inflammatory cytokines especially Interleukin-6 (IL-6). Considering that obesity represents a low grade chronic inflammatory state, a high concentration of hepcidin has been found in obese children. Elevated hepcidin level in obese children is associated with diminished response to oral iron therapy. Lactoferrin is an iron-binding multifunctional glycoprotein and has strong capacity to modulate the inflammatory response by its capacity to reduce pro-inflammatory cytokine expression in vivo, including IL-6 and hepcidin. Aim of the Work: To compare the efficacy of lactoferrin versus oral iron therapy in treatment of obese children and adolescents with iron deficiency anemia and the effect of therapy on serum hepcidin and interleukin 6 levels. Methodology: This prospective randomized clinical trial was conducted on 40 obese children and adolescents aged between 6 –18 years suffering from iron deficiency anemia (IDA). They were equally randomized into one of 2 groups. Group A received regular oral lactoferrin in a dose of 100 mg/day. Group B received regular oral iron supplementation (Ferric hydroxide polymaltose) in a dose of 6 mg elemental iron/kg /day.Baseline investigations included complete blood count (CBC), iron profile (Serum ferritin, serum iron, total iron binding capacity (TIBC), transferrin saturation), serum Interleukin 6, and serum hepcidin. Reevaluation of CBC was done monthly while iron status parameters, serum IL-6 and serum hepcidin were reevaluated after 3 months of receiving regular therapy. Results: Significant elevations in hemoglobin, MCV, MCH, Serum ferritin, serum iron and transferrin saturation with lactoferrin therapy compared to oral iron therapy. Significantly Lower TIBC after 3 months of lactoferrin therapy while the decrease in TIBC was insignificant in the iron therapy group.Lower serum hepcidin and IL6 after 3 months of lactoferrin therapy with no significant change in serum hepcidin and IL6 after iron therapy. Conclusion: This study clearly demonstrated the superiority of lactoferrin over iron use as oral in the treatment of iron deficiency anemia in obese children not only for the better response of hematological and iron status parameters and less gastrointestinal side effects but also for its effect on decreasing inflammatory biomarkers as hepcidin and IL6.

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.
