Efficacy of Intravenous Iron Infusion in Gestational Iron Deficiency Anemia in Dubai, United Arab Emirates, During 2018-2019: A Retrospective Study.

OBJECTIVE: The objective is to investigate the effectiveness of intravenous (IV) iron infusion in increasing hemoglobin levels in gestational iron deficiency anemia (GIDA) patients in a tertiary-care hospital in Dubai emirate, United Arab Emirates (UAE). METHODS: This is a retrospective cohort study of GIDA patients who were exposed to IV iron infusion supplementation. Study data of 40 cases aged 25-45 in a tertiary-care hospital in the UAE between 2018 and 2019 were analyzed. Variables accounted for were maternal age, age of gestation when IV iron was administered, and IV iron dose. RESULTS: The average hemoglobin level before the intervention was 9 g/dL, and the average change after the intervention was 10.4 g/dL with a mean of 1.4 g/dL difference between before and after the intervention. CONCLUSION: Supplementation of IV iron infusion in GIDA patients was seen to have increased the hemoglobin level after the intervention; however, the increase did not meet the recommended range of 12-16 g/dL.

The Experience of Anaemia and Ingesting Oral Iron Supplementation in Pregnancy: A Qualitative Study.

INTRODUCTION: The objective of this study was to understand the experience of iron deficiency anaemia requiring oral iron in pregnancy and the factors affecting compliance with oral iron supplementation. Participants' understanding regarding the possible consequences of anaemia in pregnancy was also explored. Feedback on a proposed randomised controlled trial of daily versus alternate day oral iron in pregnancy was sought. MATERIALS & METHODS: Following ethical approval, fourteen semi-structured one-to-one interviews were carried out using an interview tool with open-ended questions. Recruitment was carried out through social media and from an antenatal out-patient setting. Interviews were audio-recorded, transcribed and analysed thematically. RESULTS: Fatigue emerged as a predominant and troubling symptom. Awareness was often highlighted through friends/family and from healthcare professionals, particularly in first pregnancies. Knowledge surrounding the potential short-term and long-term adverse consequences of untreated anaemia however was limited. Gastro-intestinal side-effects, a previous experience of poor tolerance and forgetfulness all negatively impacted compliance with oral iron supplementation in pregnancy. Routine, a perceived improvement in fatigue with supplementation and reduced dose frequency recurred as themes which positively affected compliance. Pregnancy as a motivating factor recurred as a theme in analysis. The role of diet was felt to be important. Knowledge of iron-rich foods and absorption aids and inhibitors was good, but practice on optimal ingestion of oral iron supplementation varied. Feedback on trial acceptability was positive with the benefit of extra supportive care noted. Incorporating study visits with routine care was advised in view of time constraints. This area of research was perceived as important. CONCLUSION: In order to successfully reduce the rates of iron deficiency anaemia in pregnancy, it is crucial that all factors affecting compliance with oral iron are considered. Providing women with the important information on the possible consequences of sub optimally treated anaemia may help to improve this public health issue.

Dose-Responsive Effects of Iron Supplementation on the Gut Microbiota in Middle-Aged Women.

Oral iron supplementation is the first-line treatment for addressing iron deficiency, a concern particularly relevant to women who are susceptible to sub-optimal iron levels. Nevertheless, the impact of iron supplementation on the gut microbiota of middle-aged women remains unclear. To investigate the association between iron supplementation and the gut microbiota, healthy females aged 40-65 years (n = 56, BMI = 23 ± 2.6 kg/m2) were retrospectively analyzed from the Alberta's Tomorrow Project. Fecal samples along with various lifestyle, diet, and health questionnaires were obtained. The gut microbiota was assessed by 16S rRNA sequencing. Individuals were matched by age and BMI and classified as either taking no iron supplement, a low-dose iron supplement (6-10 mg iron/day), or high-dose iron (>100 mg/day). Compositional and functional analyses of microbiome data in relation to iron supplementation were investigated using various bioinformatics tools. Results revealed that iron supplementation had a dose-dependent effect on microbial communities. Elevated iron intake (>100 mg) was associated with an augmentation of Proteobacteria and a reduction in various taxa, including Akkermansia, Butyricicoccus, Verrucomicrobia, Ruminococcus, Alistipes, and Faecalibacterium. Metagenomic prediction further suggested the upregulation of iron acquisition and siderophore biosynthesis following high iron intake. In conclusion, adequate iron levels are essential for the overall health and wellbeing of women through their various life stages. Our findings offer insights into the complex relationships between iron supplementation and the gut microbiota in middle-aged women and underscore the significance of iron dosage in maintaining optimal gut health.

Maternal Fatigue after Postpartum Anemia Treatment with Intravenous Ferric Carboxymaltose vs. Intravenous Ferric Derisomaltose vs. Oral Ferrous Sulphate: A Randomized Controlled Trial.

(1) Background: Postpartum anemia is a common maternal complication and is recognized as a cause of impaired quality of life, reduced cognitive abilities, and fatigue. Efficient iron supplementation for the treatment of postpartum anemia is an essential component of high-quality maternal care. The optimal mode of iron supplementation has not been determined yet, whether oral or intravenous. The objective of this study was to compare postpartum anemia treatment with intravenous ferric carboxymaltose, intravenous ferric derisomaltose, and oral ferrous sulfate. (2) Methods: A single-center, open-label, randomized controlled trial. Women with hemoglobin < 100 g/L within 48 h postpartum were randomly allocated to receive intravenous ferric carboxymaltose, intravenous ferric derisomaltose, or oral ferrous sulfate. Intravenous iron was given in one or two doses, while ferrous sulfate was given as two 80 mg tablets once daily. The primary outcome was maternal fatigue measured by the Multidimensional Fatigue Inventory (MFI) six weeks postpartum. Hemoglobin, ferritin, and transferrin saturation levels were analyzed as secondary outcomes. A Kruskal-Wallis test was used for group comparison (p < 0.05 significant). (3) Results: Three hundred women were included. The MFI score at six weeks postpartum did not differ between groups (median 38 (inter-quartile range (IQR) 29-47) in the ferric carboxymaltose group, median 34 (IQR 26-42) in the ferric derisomaltose group, and median 36 (IQR 25-47) in the ferrous sulfate group; p = 0.26). Participants receiving oral iron had lower levels of hemoglobin (135 (131-139) vs. 134 (129-139) vs. 131 (125-137) g/L; p = 0.008), ferritin (273 (198-377) vs. 187 (155-246) vs. 24 (17-37) µg/L; p < 0.001) and transferrin saturation (34 (28-38) vs. 30 (23-37) vs. 24 (17-37) %; p < 0.001) than those receiving ferric carboxymaltose or ferric derisomaltose. (4) Conclusions: Intravenous ferric carboxymaltose, intravenous ferric derisomaltose, and oral ferrous sulfate had similar impacts on maternal fatigue at six weeks postpartum despite improved laboratory parameters in the intravenous groups.

Acceptability of IV iron treatment for iron deficiency anaemia in pregnancy in Nigeria: a qualitative study with pregnant women, domestic decision-makers, and health care providers.

BACKGROUND: Anaemia in pregnancy causes a significant burden of maternal morbidity and mortality in sub-Saharan Africa, with prevalence ranging from 25 to 45% in Nigeria. The main treatment, daily oral iron, is associated with suboptimal adherence and effectiveness. Among pregnant women with iron deficiency, which is a leading cause of anaemia (IDA), intravenous (IV) iron is an alternative treatment in moderate or severe cases. This qualitative study explored the acceptability of IV iron in the states of Kano and Lagos in Nigeria. METHODS: We purposively sampled various stakeholders, including pregnant women, domestic decision-makers, and healthcare providers (HCPs) during the pre-intervention phase of a hybrid clinical trial (IVON trial) in 10 healthcare facilities across three levels of the health system. Semi-structured topic guides guided 12 focus group discussions (140 participants) and 29 key informant interviews. We used the theoretical framework of acceptability to conduct qualitative content analysis. RESULTS: We identified three main themes and eight sub-themes that reflected the prospective acceptability of IV iron therapy. Generally, all stakeholders had a positive affective attitude towards IV iron based on its comparative advantages to oral iron. The HCPs noted the effectiveness of IV iron in its ability to evoke an immediate response and capacity to reduce anaemia-related complications. It was perceived as a suitable alternative to blood transfusion for specific individuals based on ethicality. However, to pregnant women and the HCPs, IV iron could present a higher opportunity cost than oral iron for the users and providers as it necessitates additional time to receive and administer it. To all stakeholder groups, leveraging the existing infrastructure to facilitate IV iron treatment will stimulate coherence and self-efficacy while strengthening the existing trust between pregnant women and HCPs can avert misconceptions. Finally, even though high out-of-pocket costs might make IV iron out of reach for poor women, the HCPs felt it can potentially prevent higher treatment fees from complications of IDA. CONCLUSIONS: IV iron has a potential to become the preferred treatment for iron-deficiency anaemia in pregnancy in Nigeria if proven effective. HCP training, optimisation of information and clinical care delivery during antenatal visits, uninterrupted supply of IV iron, and subsidies to offset higher costs need to be considered to improve its acceptability.

Low blood level in pregnancy is of public health importance and with common occurrence worldwide, but with a higher rate in low resource settings where its burden greatly affects both the mother and her baby. This low blood level is usually caused by poor intake of an iron-rich diet. It could lead to fatigue, decreased work capacity, and dizziness if not detected. Without treatment, this condition could affect the baby, possibly leading to its sudden demise in the womb, immediately after birth, or even the woman's death.The use of oral iron has been the primary treatment; however, it is associated with significant side effects, which have led to poor compliance. Fortunately, an alternative therapy in the form of a drip has been shown to overcome these challenges. However, it is not routinely used in countries like Nigeria. Moreover, being effective is different from being utilised. Therefore, this study was conducted to understand the factors that will make this treatment widely accepted.We interviewed pregnant women, family support and health care providers in 10 health facilities in Lagos and Kano States, Nigeria. Our findings revealed good attitudes to iron drip. However, its inclusion into routine antenatal health talk, training of health care providers, availability of space, drugs and health workers who will provide this care, and ensuring this drug is of low cost are some of the efforts needed for this treatment to be accepted.

High Ferritin Is Not Needed in Hemodialysis Patients: A Retrospective Study of Total Body Iron and Oral Iron Replacement Therapy.

In vivo iron levels can be adjusted through intestinal iron absorption to be maintained at a suitable level; however, optimal iron levels in hemodialysis (HD) patients are unclear. In this study, we investigated total body iron (TBI), calculated as the sum of red blood cell (RBC) iron and iron stores, during courses of low-dose oral iron replacement therapy, and evaluated in vivo iron sufficiency and its indicators in HD patients. We analyzed data on 105 courses of low-dose iron replacement therapy administered to 83 patients on maintenance HD over 7 months. We evaluated changes in TBI, RBC iron, and iron stores from the initiation of treatment to month 7 in two groups of patients, namely, iron-therapy responders and non-responders. TBI showed significant increases until month 4 and plateaued thereafter in iron-therapy responders, and tended to increase and then reached a similar plateau in non-responders (month 7: 1900 ± 447 vs. 1900 ± 408 mg). Steady-state TBI was strongly correlated with body surface area (y = 1628.6x - 791.91, R2 = 0.88, p < 0.001). We observed constant TBI during oral iron replacement therapy suggesting the activation of a "mucosal block". The results suggest that body surface area has utility for estimating the required TBI with regression equations.

Cost-effectiveness analysis of parenteral iron therapy compared to oral iron supplements in managing iron deficiency anemia among pregnant women.

OBJECTIVE: This study compared the clinical efficacy and cost-effectiveness of parenteral iron, using intravenous iron sucrose (IVIS) therapy against the standard regimen of oral iron (OI) therapy for managing iron-deficiency anemia (IDA) among pregnant women in a natural primary care setting in Gujarat. DESIGN: A prospective cost-effectiveness study was conducted in natural programme setting wherein 188 pregnant women in their 14 to 18 weeks with moderate and severe anemia women enrolled from two districts of Gujarat, and 142 were followed up until the post-partum phase. The intervention group comprised of 82 participants who were administered IVIS, while the comparison group comprised of 106 participants who were put on OI therapy. Hemoglobin (Hb) levels were measured at periodic intervals, first during enrollment and then during each month of pregnancy period and finally on the 42nd day of the post-natal period. OUTCOME MEASURES: Change in mean Hb level from baseline was the primary outcome, while the incidence of morbidity and mortality was a secondary outcome measure. RESULTS: The intervention group showed a significant incremental mean change in Hb level from 8.2 g/dl to 11.45 g/dl at the fourth follow-up, while the control group's mean Hb level reduced from 9.99 g/dl to 9.55 g/dl. The discounted cost per beneficiary for IVIS was US$ 87, while that for OI was US$ 49. The incremental cost-effectiveness ratio (ICER) was US$ 9.84, which is 0.049% of India's per capita GDP. CONCLUSION: IVIS therapy was more clinically effective and cost-effective than OI therapy among pregnant women for management of moderate and severe anemia.

Interventions in Maternal Anaemia to Reduce Maternal Mortality Rate Across India.

Anaemia is one of the most prevalent issues encountered throughout pregnancy, with Iron deficiency anaemia and megaloblastic anaemia being the most common causes in India. It is critical to address anaemia in pregnancy since it has been linked to adverse pregnancy outcomes like preterm delivery, low-birth-weight newborns, fetal mortality, and, in certain circumstances, maternal death. The maternal mortality rate (MMR) is one of the significant health challenges, particularly in developing countries. It has substantially impacted the population's social situation and requires quick management. In this review article, we discuss recent developments and advancements in treating maternal anaemia with the aid of some government health programs, which can help with lowering the risk of maternal mortality. The primary goal of this manuscript is to raise awareness about anaemia in pregnancy. We examined the literature on anaemia during pregnancy, with a view to offering current and unambiguous guidance for preventing and managing this illness, which, if not appropriately managed, can result in severe maternal and neonatal problems.

Daily versus alternate day oral iron therapy in iron deficiency anemia: a systematic review.

Daily administration of oral iron is considered the current treatment standard for treating iron deficiency anemia due to availability and reduced cost compared to intravenous iron therapy. But adverse effects like epigastric pain, heartburn, and constipation reduce compliance to daily oral iron. There is scanty evidence regarding compliance and efficacy with alternate-day iron therapy. As per our knowledge, this is the first systematic review to compare daily with alternate-day oral iron therapy. Six electronic databases including PubMed and EMBASE were searched for randomized controlled trials, quasi-experimental studies published between January 2000 to March 2023 that compared daily with alternate day iron therapy in individuals diagnosed with iron deficiency anemia. The primary outcome analyzed was a change in hemoglobin. The other hematological parameters were assessed as secondary outcomes. Risk of bias was assessed regarding randomization process, deviation from intended intervention, missing outcome data, measurement of the outcome, and selection of the reported result. Out of the 9 full-text articles, 2 were not included as one was an ongoing trial and the second one had a different study design. The reviewed trials involved 594 participants, and the study participants ranged from 19 to 200. The mean age of the participants in the reported trials was 21 ± 2 to 49 ± 16 years. There is no significant increase in hemoglobin level and also the iron indices namely ferritin, hepcidin, total iron binding capacity, and reticulocyte count between daily and alternate-day dosing of iron. However, the frequency of adverse effects especially nausea, metallic taste, and altered bowel habits are reduced with alternate-day dosing. Oral iron given daily or on alternate days did not have a significant difference in the hemoglobin levels though iron absorption may be affected in the initial few days.Trial registration: The review protocol was registered with PROSPERO (Prospero2023CRD42023393095).

Pathophysiology and management of iron deficiency anaemia in pregnancy: a review.

According to World Health Organization (WHO), iron deficiency anaemia (IDA) is considered the most prevalent nutritional deficiency worldwide, affecting approximately 30% of the global population. While gastrointestinal bleeding and menstruation in women are the primary causes of IDA, insufficient dietary iron intake and reduced iron absorption contribute to the condition. The aim of IDA treatment is to restore iron stores and normalise haemoglobin levels in affected patients. Iron plays a critical role in various cellular mechanisms, including oxygen delivery, electron transport, and enzymatic activity. During pregnancy, the mother's blood volume increases, and the growing foetus requires a significant increase in iron. Iron deficiency during pregnancy is associated with adverse outcomes such as maternal illness, low birth weight, preterm birth, and intrauterine growth restriction. Iron supplementation is commonly used to treat IDA; however, not all patients benefit from this therapy due to factors such as low compliance and ineffectiveness. In the past, IV iron therapy was underutilised due to its unfavourable and occasionally unsafe side effects. Nevertheless, the development of new type II and III iron complexes has improved compliance, tolerability, efficacy, and safety profiles. This article aims to provide an updated overview of the diagnosis and management of IDA during pregnancy. It will discuss the advantages and limitations of oral versus intravenous iron and the pathophysiology, diagnosis, treatment, and overall management of IDA in pregnancy.

Incidence of postpartum depression after treatment of postpartum anaemia with intravenous ferric carboxymaltose, intravenous ferric derisomaltose or oral ferrous sulphate: A randomized clinical trial.

Objectives: This study aimed to explore whether the type of iron preparation used to treat postpartum anaemia affects the incidence of postpartum depression and whether the risk of postpartum depression is higher in postpartum patients with anaemia who were adequately treated compared to the general postpartum population. Study design: Single-center, open-label, randomized trial. Women were allocated to receive intravenous ferric carboxymaltose, intravenous ferric derisomaltose or oral ferrous sulphate. Intravenous iron was given in one or two doses, while ferrous sulphate as two 80 mg tablets once daily. Primary outcome was postpartum depression measured by Edinburgh Postnatal Depression Scale (EPDS) six weeks postpartum. Haematological parameters were analyzed as secondary outcomes. Kruskal-Wallis test was used for group comparison (p < 0.05 significant). The chi-square test was applied to compare categorical variables as well as the group of all subjects treated for anaemia in the study with the historical data for the Slovenian postpartum population. Results: Three-hundred women with postpartum anemia (hemoglobin < 100 g/L within 48-hours postpartum) were included between September 2020 and March 2022 in tertiary perinatal center. Most characteristics were similar across groups. EPDS score at six weeks postpartum did not differ between groups. The treatment modality of postpartum anaemia did not have a statistically significant effect on the EPDS score six weeks after treatment (p = 0.10), nor did it have a statistically significant effect on the difference in EPDS scores before and after treatment (p = 0.68). The proportions of participants who scored 10 or more points on the EPDS scores at six weeks postpartum were not statistically different between the groups (p = 0.79). The proportion of participants with an EPDS score of 10 or more at six weeks postpartum in the total study population did not differ significantly from previously reported proportion of postpartum women with EPDS score of 10 or more in the general population (12 % vs. 21 %; p < 0.001). Conclusions: Maternal depression at 6 weeks postpartum did not differ in women treated for postpartum anemia with intravenous ferric carboxymaltose, intravenous ferric derisomaltose or oral ferrous sulphate. Participants with postpartum anaemia who are adequately treated with either oral or intravenous iron preparations are not at a higher risk of postpartum depression than the general population at six weeks postpartum.

Oral Iron Absorption of Ferric Citrate Hydrate and Hepcidin-25 in Hemodialysis Patients: A Prospective, Multicenter, Observational Riona-Oral Iron Absorption Trial.

Oral ferric citrate hydrate (FCH) is effective for iron deficiencies in hemodialysis patients; however, how iron balance in the body affects iron absorption in the intestinal tract remains unclear. This prospective observational study (Riona-Oral Iron Absorption Trial, R-OIAT, UMIN 000031406) was conducted at 42 hemodialysis centers in Japan, wherein 268 hemodialysis patients without inflammation were enrolled and treated with a fixed amount of FCH for 6 months. We assessed the predictive value of hepcidin-25 for iron absorption and iron shift between ferritin (FTN) and red blood cells (RBCs) following FCH therapy. Serum iron changes at 2 h (ΔFe2h) after FCH ingestion were evaluated as iron absorption. The primary outcome was the quantitative delineation of iron variables with respect to ΔFe2h, and the secondary outcome was the description of the predictors of the body's iron balance. Generalized estimating equations (GEEs) were used to identify the determinants of iron absorption during each phase of FCH treatment. ΔFe2h increased when hepcidin-25 and TSAT decreased (-0.459, -0.643 to -0.276, p = 0.000; -0.648, -1.099 to -0.197, p = 0.005, respectively) in GEEs. FTN increased when RBCs decreased (-1.392, -1.749 to -1.035, p = 0.000) and hepcidin-25 increased (0.297, 0.239 to 0.355, p = 0.000). Limiting erythropoiesis to maintain hemoglobin levels induces RBC reduction in hemodialysis patients, resulting in increased hepcidin-25 and FTN levels. Hepcidin-25 production may prompt an iron shift from RBC iron to FTN iron, inhibiting iron absorption even with continued FCH intake.

Pilot Study to Gain First Indications for the Impact of a 3-Month's Oral Intake of a Sucrosomial Iron Supplement on Hemoglobin in Iron-Deficient Blood Donors.

Introduction: Regular whole blood donors often suffer from iron deficiency (ID) or iron deficiency anemia due to the loss of 200-300 mg of iron with each donation. Hemoglobin (Hb) as donor eligibility criterion reflects iron stores only poorly. ID in blood donors is typically prevented or treated with orally administered ferrous salts, which frequently cause gastrointestinal side effects. A high daily oral iron dose is counterproductive due to hepcidin upregulation. Oral sucrosomial iron (sucriron) is encapsulated ferric pyrophosphate that may be an option for blood donors due to its supposed high bioavailability and good tolerability. Methods: This monocentric single-cohort pilot study included fifty whole blood donors (divided into premenopausal women, postmenopausal women, and men) who did not meet Hb donation criteria. Participants aged 18-65 years with ferritin <30 ng/mL and venous Hb <12.5 g/dL in women and Hb <13.5 g/dL in men received oral sucriron (30 mg iron) for 90-120 days. Primary endpoints were the increase of Hb and ferritin. Results: Forty-seven participants completed the study. With the limitation that no control group was included, there was a substantial overall median increase of 0.94 g/dL Hb and 4.97 ng/mL ferritin (standardized on 90 days of iron intake). These value improvements were likewise observed in each of the subgroups. sucriron was very well tolerated, with almost no gastrointestinal side effects identified. Conclusion: A clear increase of Hb and ferritin was observed after the intake of sucriron, so it may be a reasonable and useful alternative to traditional oral iron therapy. The ease of administration, pleasant taste, dietary supplement status, and, most importantly, good tolerability highlight the value of sucriron supplementation.

Safety monitoring of oral iron supplements in pregnant women with anemia: a multi-center observational clinical study.

Aims: To investigate the safety of oral iron therapy in pregnant women with iron-deficiency anemia (IDA) in the real world. Methods: A retrospective analysis was performed on 1792 pregnant patients with IDA who received oral iron supplements from 12 hospitals in Shandong Province from 1 April to 31 June 2021; follow-up and adverse reactions were recorded. They were divided into six groups according to the treatment drugs. Results: The overall adverse reaction rate was 15.4%, and the main adverse reaction site was the digestive system. The incidence of all kinds of oral iron adverse reactions from high to low in order: compound ferrous sulfate and folic acid tablets (21.88%); iron proteinsuccinylate oral solution (20.90%); ferrous succinate tablets (19.76%); ferrous succinate sustained-release tablets (18.00%); iron polysaccharide complex capsule (12.06%); and iron dextran oral solution (6.94%). It was found that there was a significant difference in the incidence of adverse reactions among the six drugs (p < 0.05). Pairwise comparison showed that the incidence of adverse reactions was higher in the iron proteinsuccinylate oral solution than that in the iron polysaccharide complex capsule (p < 0.05). There was no significant difference in the incidence of adverse reactions in different ages (p > 0.05), but there was a significant difference in the incidence of adverse reactions in different gestational ages (p < 0.05). In Adverse Drug Reaction (ADR) patients, the adverse reaction result of most patients is recovery or improvement, and there was no serious adverse reaction outcome such as sequela and death. Conclusion: All the adverse reactions of oral iron were mainly gastrointestinal adverse reactions, and no heavy adverse reactions were found. Iron proteinsuccinylate oral solution has a higher incidence of adverse reactions than iron polysaccharide complex capsule. The results showed that oral iron was safer for anemia patients during pregnancy.

Safety of oral iron in the treatment of iron-deficiency anemia during pregnancy Introduction: The safety of different oral iron agents varies. At present, the safety evaluation of iron supplements in the treatment of anemia during pregnancy is mainly focused on intravenous iron supplements, and there is no comprehensive study on the safety of commonly used oral iron supplements. This study compared the safety of six commonly used oral iron supplements in the treatment of iron-deficiency anemia during pregnancy, aiming to provide a reference for clinical medication. Methods: We conducted a study involving 1792 patients in 12 hospitals in Shandong Province from 1 April to 31 June 2021. Results: Among the six groups, 276 ADR patients reported 302 adverse reactions. There were significant differences in the rates of adverse reactions among the six oral iron agents, and the incidence of adverse reactions in the iron proteinsuccinylate oral solution was significantly higher than that of iron polysaccharide complex capsules. The main incidence of adverse reactions was constipation (6.96%), and most of the outcomes were cured or improved. Conclusion: In this study, there were no heavy adverse reactions. The incidence of adverse reactions of iron proteinsuccinylate oral was higher than that of iron polysaccharide compound capsule. The results showed that oral iron had a good safety in patients with anemia during pregnancy.

Sucrosomial® Iron: An Updated Review of Its Clinical Efficacy for the Treatment of Iron Deficiency.

Iron deficiency (ID) and iron deficiency anemia (IDA) are highly prevalent worldwide. Oral iron salts, especially ferrous sulfate, are commonly used for the treatment of iron deficiency (ID). However, its use is associated with gastrointestinal side effects, thus compromising treatment compliance. Intravenous iron administration is a more costly and logistically complex alternative and is not risk-free, as infusion and hypersensitivity reactions may occur. Sucrosomial® iron is an oral formulation consisting of ferric pyrophosphate conveyed by a phospholipid and sucrester matrix (sucrosome®). Intestinal Sucrosomial® iron absorption is mediated by enterocytes and M cells, through the paracellular and transcellular routes, and occurs mostly as intact particles. These pharmacokinetic properties of Sucrosomial® iron result in higher iron intestinal absorption and excellent gastrointestinal tolerance compared to oral iron salts. The evidence derived from clinical studies supports the use of Sucrosomial® iron as a valid first option for the treatment of ID and IDA, especially for subjects who are intolerant or refractory to conventional iron salts. Newer evidence also demonstrates the effectiveness of Sucrosomial® iron, with a lower cost and fewer side effects, in certain conditions usually treated with IV iron in current clinical practice.

Effect of Educational Handouts With Standard Therapy Versus Standard Therapy Alone on Compliance With Oral Iron Supplementation in Antenatal Women With Iron Deficiency Anemia: A Randomized Controlled Trial.

Background Iron requirements rise dramatically throughout the second and third trimesters of pregnancy. Pregnant women are more susceptible to anemia because their need for iron increases during pregnancy, which is difficult to achieve through diet alone. Methodology A randomized controlled trial (non-blinded and parallel group) was undertaken with the recruitment of 174 women. However, 35 women were lost to follow-up, and the study was ultimately completed with 139 participants distributing 68 women in Group A (intervention group) and 71 women in Group B (non-interventional group). Educational handouts were explained to the participants with iron supplements in Group A and only supplements were given to Group B, and the participants were followed up till three months before the recruitment period. Compliance with iron supplementation and a rise in hemoglobin were noted. Results In this study, maximum women were in the 22-30 years age group and were almost evenly distributed with respect to parity with no statistically significant difference in the groups. All the participants were started with oral iron therapy. No additional parenteral iron therapy was given. Women in Group A showed good compliance for iron supplementation than those in Group B. It was determined that this difference was statistically insignificant (>0.05). In the majority of women, the reason for poor compliance was frustration to follow oral iron therapy daily (52.3% in Group A and 21.7% in Group B). There were other reasons like forgetfulness, heartburn, vomiting, constipation, and nausea as the reason for poor compliance. The hemoglobin levels were compared at the recruitment and a mean rise in hemoglobin levels was noted in groups A and B at the follow-up period after three months. There was a greater mean rise in hemoglobin concentration in Group A (1.28) than in Group B (0.63), which was statistically insignificant (>0.05). Conclusion The current study found that among pregnant women with iron-deficient anemia, instructional handouts did not promote compliance with oral iron treatment. The main reasons for low compliance were frustration with taking the oral drug, followed by forgetfulness, heartburn, vomiting, constipation, and nausea. In pregnant females with anemia brought on by iron deficiency, educational handouts did not enhance hemoglobin status.

Antenatal Optimization of Maternal Anemia Leads to Decreased Risks of Maternal Morbidity.

Purpose of Review: Our review focuses on the appropriate use of intravenous iron to increase the likelihood of achieving target hemoglobin levels prior to delivery to reduce maternal morbidity. Recent Findings: Iron deficiency anemia (IDA) is a leading contributor to severe maternal morbidity and mortality. Prenatal treatment of IDA has been demonstrated to reduce the likelihood of adverse maternal outcomes. Recent investigations of intravenous iron supplementation have demonstrated superior efficacy and high tolerability for the treatment of IDA in the third trimester, compared against oral regimens. However, it is unknown whether this treatment is cost-effective, available to clinicians, or acceptable to patients. Summary: Intravenous iron is superior to the oral treatment of IDA; however, its use is limited by the lack of implementation data.

Deficiencia de hierro en enfermedad renal crónica

Contexto: la deficiencia de hierro es un trastorno frecuentemente observado en pacientes con enfermedad renal crónica (ERC), sobre todo en estadios avanzados. Su presencia se asocia a una mayor morbilidad y mortalidad. La deficiencia de hierro puede ser absoluta o funcional. La deficiencia absoluta se refiere a una ausencia o una reducción de las reservas de hierro, mientras que la deficiencia funcional se define por la presencia de depósitos de hierro adecuados pero con una disponibilidad insuficiente de hierro para su incorporación en los precursores eritroides. Varios factores de riesgo contribuyen a la deficiencia absoluta y funcional de hierro en ERC, incluyendo pérdidas hemáticas, absorción alterada de hierro e inflamación crónica. Objetivo: con esta revisión narrativa se pretende presentar las definiciones, los aspectos fisiopatológicos, los criterios diagnósticos y las medidas terapéuticas en el paciente con diagnóstico de ERC con deficiencia de hierro. Metodología: se realizó una revisión no sistemática de la literatura en la base de datos PubMed, incluyendo además las guías internacionales más utilizadas que abordan el tema de deficiencia de hierro en ERC. Resultados: se incluyeron un total de 30 referencias bibliográficas. La deficiencia de hierro puede ser absoluta o relativa y el déficit absoluto de hierro se produce con valores de ferritina 100 mcg/l, pero con una TSAT < 20 %. El tratamiento del déficit absoluto consta de reposición de hierro oral o endovenoso y en pacientes que aún no reciben diálisis, se puede hacer una prueba terapéutica con hierro oral, de no haber respuesta se optará por hierro endovenoso, mientras que en pacientes que sí reciben diálisis, la medida ideal es el hierro endovenoso, preferiblemente en preparaciones que permitan esquemas de altas dosis y bajas frecuencias de administración. Las metas propuestas por las distintas guías presentan variaciones entre 500 y 700 mcg/l de ferritina. Conclusiones: el déficit de hierro debe buscarse activamente en pacientes con ERC, ya que su presencia y la falta de intervención conlleva a un incremento en los desenlaces adversos. La terapia con hierro es el pilar del tratamiento y la elección del agente a utilizar dependerá de las características individuales del paciente y de la disponibilidad de las preparaciones de hierro oral o endovenoso.

Background: Iron deficiency is a disorder frequently observed in patients with chronic kidney disease (CKD), especially in advanced stages. Its presence is associated with increased morbidity and mortality. Iron deficiency can be absolute or functional. Absolute deficiency refers to absent or reduced iron stores, while functional deficiency is defined by the presence of adequate iron stores but insufficient iron availability for incorporation into erythroid precursors. Several risk factors contribute to absolute and functional iron deficiency in CKD, including blood fi, impaired iron absorption, and chronic inflammation. Purpose: With this narrative review, it is intended to present the details, pathophysiological aspects, diagnostic criteria and therapeutic options in patients diagnosed with chronic kidney disease with iron deficiency. Methodology: A non-systematic review of the fi ron ra was carried out, in the PubMed database, also including the most used international guidelines that address the issue fi ron deficiency in chronic kidney disease. Results: A total of 30 bibliographical references were included. Iron deficiency can be absolute or relative. The absolute iron deficiency occurs with ferritin values 100 mcg/l but with a TSAT <20 % Treatment of absolute deficiency consists of oral or intravenous iron replacement. In a patient who is not yet receiving dialysis, a therapeutic trial with oral iron can be done, if there is no response, intravenous iron will be chosen. In patients receiving dialysis, the ideal measure is intravenous iron, preferably in preparations that allow high-dose schemes and low frequencies of administration. The goals proposed by the different guidelines present variations between 500 and 700 mcg/l d ferritin. Conclusions: iron deficiency should be actively sought in patients with CKD, since its presence and lack of intervention leads to an increase in adverse outcomes. Iron therapy is the mainstay of treatment; the choice of the agent to be used depends on the individual characteristics of the patient and the availability of oral or intravenous iron preparations.

Impaired pancreatic beta-cell function after a single dose of oral iron: A before-and-after (pre-post) study.

BACKGROUND: Although in vitro and animal studies have shown that iron loading in pancreatic beta cells impairs insulin secretion, no human studies have documented the acute effects of oral iron on beta-cell insulin secretory capacity. In the present study, we determined beta-cell insulin secretory capacity at baseline and after a single oral dose of iron (ferrous sulphate, 120 mg elemental iron) in healthy male individuals. METHODS: Fifteen healthy male volunteers underwent an oral glucose tolerance test (OGTT) to document baseline glucose tolerance and insulin secretion kinetics (baseline OGTT). One week later, the same subjects underwent a second OGTT, 2 h after an oral dose of ferrous sulphate (120 mg of elemental iron) (post-iron OGTT). Changes in disposition index, insulin secretion kinetics, glucose tolerance, insulin resistance, insulin clearance and iron-related parameters in serum were determined. RESULTS: Compared to baseline OGTT, the areas under the curve (AUC) for serum iron and transferrin saturation increased by 125% and 118%, respectively, in the post-iron OGTT. The disposition index decreased by 20% (p = 0.009) and the AUC for glucose concentrations increased by 5.7% (p < 0.001) during the post-iron OGTT. The insulin secretion rate was marginally lower during the first hour (-3.5%, p = 0.63), but became significantly higher during the second hour (22%, p = 0.005) of the post-iron OGTT. Insulin resistance and insulin clearance rate were not affected by iron intake. CONCLUSIONS: The decrease in disposition index and glucose tolerance observed after the oral dose of iron points to an acute iron-induced impairment in pancreatic beta-cell insulin secretory capacity.

The role of oral iron in the treatment of adults with iron deficiency.

Iron deficiency is the most common nutrient deficiency in the world, affecting over 20% of premenopausal women worldwide. Oral iron supplementation is often the first-line treatment for the acute and chronic management of iron deficiency due to its ease and accessibility. However, there is no consensus on the optimal formulation or dosing strategy, or which patients should be preferentially treated with intravenous iron. Management of iron deficiency is complicated by the hepcidin-ferroportin iron regulatory pathway, which has evolved to prevent iron overload and thereby creates an inherent limit on gastrointestinal iron uptake and efficacy of oral iron. Unabsorbed iron propagates many of the side effects that complicate oral iron use including dyspepsia and constipation, all of which can thus be exacerbated by excessive oral iron doses. Daily low dose and every other day dosing protocols have attempted to bypass this physiologic bottleneck to allow for effective absorption and limit side effects; however, this approach has still resulted in low fractional iron absorption. In the following manuscript, we review the pathophysiology of iron absorption and current evidence for various preparations of oral iron. Lastly, we highlight opportunities for further study to advance the care of individuals affected by iron deficiency.
