[Iron supplementation in patients with chronic inflammatory bowel disease: recommendations for a practical approach]. / Eisensupplementation bei Patienten mit chronisch-entzündlicher Darmerkrankung: Empfehlungen zur praxisnahen Vorgehensweise.

Iron deficiency is the predominant cause of anemia. Iron deficiency anemia plays a major role, especially in patients with inflammatory bowel disease (IBD), and is the most common extraintestinal manifestation and IBD-associated systemic complication. The presence of anemia leads to a reduction in quality of life in patients with IBD associated with limitations in physical, emotional, and cognitive function. In addition, it is associated with an increased hospitalization rate. For this reason, iron supplementation is of particular importance. Oral and intravenous iron supplements are used to treat iron deficiency. Due to the lack of absorption and gastrointestinal side effects of oral substitution, intravenous supplementation is becoming increasingly important. However, there are still certain concerns about intravenous administration.With the help of this review, we want to address the topic of iron substitution in patients with IBD, summarize current guideline recommendations, and provide a practical approach.

Should echocardiogram be undertaken routinely when a child has severe iron deficiency anaemia?

Iron deficiency anaemia (IDA) is common in children. Treatment usually consists of oral iron therapy and, if severe, inpatient hospitalisation with blood transfusion. Providers may also undertake an echocardiogram, depending on availability and the severity of anaemia. A male toddler with nutritional IDA, haemoglobin of 1.7 g/dL (the lowest level in the literature) and hypertension had left ventricular hypertrophy (LVH) on the initial echocardiogram. He was managed acutely with judicious blood transfusion, followed by oral iron supplementation and anti-hypertensive medication at discharge. Repeat echocardiogram a month later demonstrated slight improvement of the LVH but the hypertension persisted at follow-up 6 months later. There was complete resolution of the findings a year later. In chronic nutritional IDA, there can be structural cardiac changes which can affect the acute management and requires close follow-up. It is important to use echocardiography in such severe cases.Abbreviations: CHF: congestive heart failure; CM: cardiomyopathy; DCM: dilated cardiomyopathy; ICU: intensive care unit; IDA: iron deficiency anaemia; IVSd: interventricular septum in diastole; LA: left atrium; LV: left ventricle; LVEDD: left ventricular end-diastolic diameter; LVH: left ventricular hypertrophy; LVM: left ventricular mass; LVPWd: left ventricular posterior wall end-diastole; PRBC: packed red blood cells.

Current concepts in postpartum anemia management.

PURPOSE OF REVIEW: Postpartum anemia (PPA) is common in women after childbirth and affects about 50-80% of all women worldwide. Iron deficiency (ID) is the main cause for anemia and constitutes a potentially preventable condition with great impact on the mother's physical and mental condition after delivery. In most cases, PPA is associated with antenatal ID and peripartum blood losses. Numerous published studies confirmed the positive effect of PPA diagnosis and treatment. RECENT FINDINGS: Iron deficiency as well as iron deficiency anemia (IDA) are common in the postpartum period and represent significant health problems in women of reproductive age. SUMMARY: Important movements towards early detection and therapy of postpartum anemia have been observed. However, postpartum anemia management is not implemented on a large scale as many healthcare professionals are not aware of the most recent findings in the field. Diagnosis and therapy of PPA, particularly iron supplementation in ID and IDA, has proven to be highly effective with a tremendous effect on women's wellbeing and outcome.

Oral iron therapy: Current concepts and future prospects for improving efficacy and outcomes.

Iron deficiency (ID) and iron-deficiency anaemia (IDA) are global public health concerns, most commonly afflicting children, pregnant women and women of childbearing age. Pathological outcomes of ID include delayed cognitive development in children, adverse pregnancy outcomes and decreased work capacity in adults. IDA is usually treated by oral iron supplementation, typically using iron salts (e.g. FeSO4 ); however, dosing at several-fold above the RDA may be required due to less efficient absorption. Excess enteral iron causes adverse gastrointestinal side effects, thus reducing compliance, and negatively impacts the gut microbiome. Recent research has sought to identify new iron formulations with better absorption so that lower effective dosing can be utilized. This article outlines emerging research on oral iron supplementation and focuses on molecular mechanisms by which different supplemental forms of iron are transported across the intestinal epithelium and whether these transport pathways are subject to regulation by the iron-regulatory hormone hepcidin.

Iron Deficiency Anemia: An Updated Review.

BACKGROUND: Worldwide, iron deficiency anemia is the most prevalent nutritional deficiency disorder and the leading cause of anemia in children, especially in developing countries. When present in early childhood, especially if severe and prolonged, iron deficiency anemia can result in neurodevelopmental and cognitive deficits, which may not always be fully reversible even following the correction of iron deficiency anemia. OBJECTIVE: This article aimed to familiarize physicians with the clinical manifestations, diagnosis, evaluation, prevention, and management of children with iron deficiency anemia. METHODS: A PubMed search was conducted in February 2023 in Clinical Queries using the key term "iron deficiency anemia". The search strategy included all clinical trials (including open trials, non-randomized controlled trials, and randomized controlled trials), observational studies (including case reports and case series), and reviews (including narrative reviews, clinical guidelines, and meta-analyses) published within the past 10 years. Google, UpToDate, and Wikipedia were also searched to enrich the review. Only papers published in the English literature were included in this review. The information retrieved from the search was used in the compilation of the present article. RESULTS: Iron deficiency anemia is most common among children aged nine months to three years and during adolescence. Iron deficiency anemia can result from increased demand for iron, inadequate iron intake, decreased iron absorption (malabsorption), increased blood loss, and rarely, defective plasma iron transport. Most children with mild iron deficiency anemia are asymptomatic. Pallor is the most frequent presenting feature. In mild to moderate iron deficiency anemia, poor appetite, fatigability, lassitude, lethargy, exercise intolerance, irritability, and dizziness may be seen. In severe iron deficiency anemia, tachycardia, shortness of breath, diaphoresis, and poor capillary refilling may occur. When present in early childhood, especially if severe and prolonged, iron deficiency anemia can result in neurodevelopmental and cognitive deficits, which may not always be fully reversible even with the correction of iron deficiency anemia. A low hemoglobin and a peripheral blood film showing hypochromia, microcytosis, and marked anisocytosis, should arouse suspicion of iron deficiency anemia. A low serum ferritin level may confirm the diagnosis. Oral iron therapy is the first-line treatment for iron deficiency anemia. This can be achieved by oral administration of one of the ferrous preparations, which is the most cost-effective medication for the treatment of iron deficiency anemia. The optimal response can be achieved with a dosage of 3 to 6 mg/kg of elemental iron per day. Parenteral iron therapy or red blood cell transfusion is usually not necessary. CONCLUSION: In spite of a decline in prevalence, iron deficiency anemia remains a common cause of anemia in young children and adolescents, especially in developing countries; hence, its prevention is important. Primary prevention can be achieved by supplementary iron or iron fortification of staple foods. The importance of dietary counseling and nutritional education cannot be overemphasized. Secondary prevention involves screening for, diagnosing, and treating iron deficiency anemia. The American Academy of Pediatrics recommends universal laboratory screening for iron deficiency anemia at approximately one year of age for healthy children. Assessment of risk factors associated with iron deficiency anemia should be performed at this time. Selective laboratory screening should be performed at any age when risk factors for iron deficiency anemia have been identified.

Umbilical cord management - the first opportunity to improve healthcare disparities.

This review focuses on iron deficiency and iron deficiency anemia in women and children in the United States. These are common, fixable problems that disproportionally affect minority populations. There are many opportunities for successful screening and management. The knowledge and awareness for identification and treatment of our populations' commonest deficiency is crucial.

Expert consensus on improving iron deficiency anemia management in obstetrics and gynecology in Asia.

Iron deficiency anemia (IDA) is a major health burden among women in Asia. Key issues in IDA management in Asia are under-diagnosis and under-treatment. The lack of Asia-specific guidelines, and suboptimal utilization of treatment compounds the management of IDA. To address these gaps, a panel of 12 experts in obstetrics, gynecology, and hematology from six regions in Asia convened to review current practices and clinical evidence and provide practical guidance on IDA diagnosis and management in Asian women. The Delphi approach was used to obtain objective opinions and attain consensus on statements pertaining to awareness, diagnosis, and management of IDA. In total, 79 statements attained consensus and are summarized to provide guidance on raising awareness of IDA and approaches for improved diagnosis and treatment of IDA among women in various settings: pregnancy, postpartum, heavy menstrual bleeding, gynecologic cancers, and perioperative care. This clinician-led consensus integrates appropriate recommendations based on clinical evidence and best practices and is intended to guide decision making in the management of iron deficiency/IDA in women. The expert panel raises a call for timely diagnosis and utilization of appropriate treatment, including use of high-dose intravenous iron, stringent blood management, and interdisciplinary collaboration, for optimization of IDA management among women in Asia.

[Anemia: Diagnostics and Therapy]. / Ambulante Anämiediagnostik und -therapie.

The most common cause of anemia is iron deficiency, followed by anemia of chronic disease, which is due to an inflammatory reaction in chronic diseases such as heart failure, renal failure, rheumatoid diseases and cancer. Also from the therapeutic point of view, it is useful to divide iron deficiency anemia into two forms: absolute and functional iron deficiency. Absolute iron deficiency is characterized by low iron stores and low total iron. In functional iron deficiency, a sufficient amount of storage iron is present, but it cannot be mobilized. Therapy of iron deficient anemia should always eliminate the underlying cause. The goal of therapy is sustained normalization of hemoglobin concentration and total body iron. Therapy for absolute iron deficiency focuses on improving iron stores, eliminating chronic blood losses, and optimizing iron absorption via an iron-rich diet and iron supplementation. In the case of functional iron deficiency with inflammation present, IV iron supplementation is recommended in certain situations in addition to treatment of the underlying disease, especially in patients with cancer.

Synbiotic supplement for treatment of iron deficiency anaemia in haemodialysis patients: A randomized controlled trial.

BACKGROUND: There is evidence that probiotics can increase the availability of iron. The aim of current study was to determine the effects of synbiotic supplementation on the haematological parameters and anaemia in haemodialysis patients. METHODS: This study was a randomized, double-blind, placebo-controlled trial. Fifty patients were randomly selected from the haemodialysis section of Vaseii Hospital, Sabzevar, Iran. Subjects in the symbiotic and control groups received 2 capsules of synbiotic supplement or placebo, respectively, once a day for 8 weeks. Blood samples were divided into two test tubes in equal volumes. Blood haemoglobin, haematocrit, transferrin saturation, red blood cells (RBCs), and total iron binding capacity (TIBC) were measured with auto-analyser. Ferritin was determined using Sandwich enzyme-linked immunosorbent assay (ELISA). RESULTS: Twenty tree patients in each group completed the study. Significant results were recorded in synbiotic groups regarding the concentration of blood haemoglobin, haematocrit, transferrin saturation, the number of RBCs, and serum ferritin compare to placebo group (P < .05). At the end of week 8, TIBC significantly decreased in synbiotic than placebo group (P < .05). CONCLUSION: Synbiotic supplementation could be a safe and promising candidate in improving anaemia in CKD patients.

Current concepts in preoperative anemia management in obstetrics.

PURPOSE OF REVIEW: The purpose of this article is to provide an overview of currently recommended treatment approaches for anemia during pregnancy, with a special focus on iron deficiency and iron deficiency anemia (IDA). RECENT FINDINGS: As consistent patient blood management (PBM) guidelines in obstetrics are still lacking, recommendations regarding the timing of anemia screening and the treatment recommendations for iron deficiency and IDA during pregnancy are still controversial. Based on increasing evidence, early screening for anemia and iron deficiency should be recommended at the beginning of each pregnancy. To reduce maternal and fetal burden, any iron deficiency, even without anemia, should be treated as early as possible during pregnancy. While oral iron supplements administered every other day are the standard treatment in the first trimester, the use of intravenous iron supplements is increasingly suggested from the second trimester onwards. SUMMARY: The treatment of anemia, and more specifically iron deficiency anemia during pregnancy, holds many possibilities for improvement. The fact that the period of risk is known well in advance and thus there is a long optimization phase is per se an ideal prerequisite for the best possible therapy of treatable causes of anemia. Standardization of recommendations and guidelines for screening and treatment of IDA in obstetrics is required for the future. In any case, a multidisciplinary consent is the precondition for a successfully implementation of anemia management in obstetrics to establish an approved algorithm easily enabling detection and treatment of IDA during pregnancy.

Prevalence, Pathogenesis and Management of Anemia in Inflammatory Bowel Disease: An IG-IBD Multicenter, Prospective, and Observational Study.

BACKGROUND: Anemia is a common extraintestinal manifestation of inflammatory bowel disease (IBD), with a 6% to 74% prevalence and a negative impact on patient survival and quality of life, although the prevalence is apparently declining due to improved disease treatment. We aimed to investigate the prevalence, pathogenesis, and clinical correlates of anemia in Italian patients with IBD. METHODS: A multicenter, prospective, observational study, involving 28 Italian gastroenterology centers, was conducted to investigate the epidemiology and consequences of IBD-associated anemia. Clinical and laboratory data of anemic patients were obtained at study enrolment. RESULTS: Anemia was diagnosed in 737 of 5416 adult IBD outpatients (prevalence 13.6%); females were more commonly affected than males (odds ratio, 1.5; 95% confidence interval [CI], 1.2-1.7) and had more severe anemia. In the majority of cases, anemia was due to iron deficiency (62.5% of cases; 95% CI, 58.3%-66.6%), either isolated or in association with inflammation and/or vitamin deficiencies; anemia of inflammation accounted for only 8.3% of cases. More severe anemia was associated with increasing fatigue and worse quality of life. Only 68.9% of anemic patients with iron deficiency (95% CI, 63.4%-73.8%) and 34.6% of those with vitamin deficiencies (95% CI, 26.2%-44.2%) were properly treated with supplementation therapy. CONCLUSIONS: In Italy, the prevalence of IBD-associated anemia is lower than previously reported. Anemia of IBD is most commonly due to iron deficiency and contributes to fatigue and poor quality of life, but remains untreated in a large proportion of patients with iron and/or vitamin deficiencies. This study is registered at clinicaltrials.gov as NCT02872376.

The prevalence of inflammatory bowel disease­associated anemia is 13.6%. The prevalence is higher among females younger than 50. Anemia is usually due to iron deficiency and adversely affects fatigue and quality of life. Many patients with iron or vitamin deficiency (31% and 65%, respectively) remain untreated.

Effectiveness of Dietary Interventions to Treat Iron-Deficiency Anemia in Women: A Systematic Review of Randomized Controlled Trials.

Iron-deficiency anemia is the most frequent nutritional deficiency, with women of reproductive age being particularly at risk of its development. The aim of the systematic review was to assess the effectiveness of dietary interventions to treat iron-deficiency anemia in women based on the randomized controlled trials. The systematic review was conducted according to the PRISMA guidelines and registered in the PROSPERO database (CRD42021261235). The searching procedure was based on PubMed and Web of Science databases, while it covered records published until June 2021. It included all randomized controlled trials assessing effectiveness of various dietary interventions on treatment of iron-deficiency anemia in women of childbearing age. The total number of 7825 records were screened, while 14 of them were finally included in the systematic review. The studies were screened, included, and reported, and the risk of bias was assessed using the revised Cochrane risk-of-bias tool for randomized trials by two independent researchers. The included studies compared the effectiveness of various dietary interventions with supplementation, placebo, control, or any other dietary intervention, while the assessed dietary interventions were based either on increasing iron supply and/or on increasing its absorption (by increasing vitamin C or vitamin D or decreasing phytate intake). The duration of applied intervention was diversified from 3 months or less, through 4 or 5 months, to half of a year or more. Among the assessed biochemical measures, the following were analyzed in majority of studies: hemoglobin, ferritin, transferrin receptor, hematocrit, and transferrin. The majority of included studies supported the influence of dietary interventions on the treatment of iron-deficiency anemia, as the applied dietary intervention was not effective in only three studies. The majority of included studies were assessed as characterized by medium risk of bias, while the overall risk was high for only four studies, which resulted from the randomization process, deviations from the intended interventions, and selection of the reported result. The majority of included studies were conducted for increasing iron supply and/or increasing vitamin C supply; however, only for the interventions including increasing iron supply and simultaneously increasing its absorption by vitamin C supply were all results confirmed effective. Vitamin D also seems to be an effective dietary treatment, but further studies are necessary to confirm the observations. Considering this fact, dietary interventions recommended for anemic female patients should include increased intake of iron and vitamin C.

Pathophysiology and therapeutic management of anemia in gastrointestinal disorders.

INTRODUCTION: Anemia is a common complication of gastrointestinal (GI) disorders, with a prevalence up to 60% in celiac disease (CeD) and inflammatory bowel disease (IBD). Iron deficiency anemia (IDA) is the most prevalent form of anemia in these conditions, but chronic inflammation and vitamin B12 deficiency represent other common contributing mechanisms, especially in IBD. AREAS COVERED: We discuss the pathogenesis of anemia in various medical GI disorders, the sometime problematic distinction between IDA, anemia of inflammation (AI) and the association of the two, and therapeutic and preventive measures that can be useful for the management of anemia in GI disorders. Unfortunately, with the exception of IDA and AI in IBD, large RCT concerning the treatment of anemia in GI disorders are lacking. EXPERT OPINION: Anemia management strategies in GI disorders are outlined, with a focus on the main prevention, diagnostic, and therapeutic measures. Specific problems and situations such as the role of gluten-free diet for IDA treatment in CeD, the choice between oral and parenteral supplementation of iron or vitamin B12 in carential anemias, the use of endoscopic procedures to stop bleeding in intestinal angiodysplasia and preventive/treatment strategies for NSAID-associated GI bleeding are discussed.

Optimal iron content in ready-to-use therapeutic foods for the treatment of severe acute malnutrition in the community settings: a protocol for the systematic review and meta-analysis.

INTRODUCTION: The current standard of care for children with severe acute malnutrition (SAM) involves using ready-to-use therapeutic food (RUTF) to promote growth; however, the precise formulation to achieve optimal recovery remains unclear. Emerging research suggests that alternative RUTF formulations may be more effective in correcting SAM-related complications such as anaemia and iron deficiency. This systematic review commissioned by the WHO aims to synthesise the most recent research on the iron content in RUTF and related products in the community-based treatment of uncomplicated severe malnutrition in children aged 6 months and older. METHODS AND ANALYSIS: We will search multiple electronic databases. We will include randomised controlled trials and non-randomised studies with a control arm. The intervention group will be infants who received RUTF treatments other than the current recommended guidelines set forth by the WHO. The comparison group is children receiving RUTF containing iron at the current WHO-recommended level of 1.9 mg/100 kcal (10-14 mg/100 g). The primary outcomes of interest include blood haemoglobin concentration, any anaemia, severe anaemia, iron-deficiency anaemia, recovery from SAM and any adverse outcomes. We will use meta-analysis to pool findings if sufficient homogeneity exists among included studies. The risk of bias in studies will be evaluated using the Cochrane risk of bias-2. We will use the Grading of Recommendations Assessment, Development, and Evaluation(GRADE) approach to examine the overall certainty of evidence. ETHICS AND DISSEMINATION: This is a systematic review and will not involve direct contact with human subjects. The findings of this review will be published in a peer-reviewed journal and will guide the WHO's recommendation on the optimal iron content in RUTFs for the treatment of SAM in children aged 6-59 months.

Iron Status, Anemia, and Iron Interventions and Their Associations with Cognitive and Academic Performance in Adolescents: A Systematic Review.

In adolescents, iron-deficiency anemia is the leading cause of disability-adjusted life years lost. The World Health Organization recommends delivering iron supplementation through school-based platforms, requiring partnerships with the education sector. This anemia-reduction intervention is valued for the perceived benefits of improved learning and school performance. This article aims to systematically review the available evidence on the relationship between iron status and anemia and impacts of iron interventions on cognitive and academic performance in adolescents. Fifty studies were included: n = 26 cross-sectional and n = 24 iron-containing interventions. Our review suggests that iron status and anemia may be associated with academic performance in some contexts and that iron supplementation during adolescence may improve school performance, attention, and concentration. However, nearly all supplementation trials were judged to have moderate or high risk of bias. We did not find evidence suggesting that iron status and anemia influenced or were associated with attention, intelligence, nor memory in adolescents. Further, iron supplementation did not improve memory and recall or intelligence. Overall, more high-quality research is needed to guide programmers and policy makers to understand the relationships between anemia and educational performance and the potential impacts of iron interventions, which effectively reduce anemia, on adolescents' learning and school performance.

[Preoperative anemia in patients with rheumatic diseases]. / Präoperative Anämie beim Rheumatiker.

A preoperative anemia is an independent risk factor for the occurrence of complications during and after surgical interventions. It is associated with an increased length of hospital stay, higher mortality and an increased use of blood transfusions. Anemia affects some 30-70% of patients suffering from inflammatory rheumatic diseases, mostly caused by iron deficiency and/or chronic inflammation. The possibilities to treat anemia in rheumatic patients were extremely limited for a long period of time as older studies showed life-threatening side effects, the need of high doses of iron supplements or the occurrence of many nonresponders. Further development of the supplements, new dosage schemes and the combination of supplements increased the efficacy and reduced the occurrence of side effects to a minimum. In addition to orthopedic surgical interventions for rheumatism that despite new therapeutic options in some cases still represent the only way to alleviate the complaints, more and more patients with inflammatory rheumatic diseases also need surgical interventions due to comorbidities. Therefore, anemia should be clarified and preoperatively treated in accordance with the new study situation, to minimize additional complications due to anemia and to increase patient safety.

Iron parameters in pregnant women with beta-thalassaemia minor combined with iron deficiency anaemia compared to pregnant women with iron deficiency anaemia alone demonstrate the safety of iron supplementation in beta-thalassaemia minor during pregnancy.

In patients with beta-thalassaemia intermedia or major, hepcidin induces iron overload by continuously promoting iron absorption. There have been no studies in pregnant women with beta-thalassaemia minor combined with iron deficiency anaemia (IDA), examining whether hepcidin is inhibited by GDF15, as may occur in patients with beta-thalassaemia intermedia or major, or whether the iron metabolism characteristics and the effect of iron supplementation are consistent with simple IDA in pregnancy. We compared and analysed routine blood parameters, iron metabolism parameters, the GDF15 levels, and the hepcidin levels among four groups, namely the beta-thalassaemia (ß) + IDA, ß, IDA, and normal groups. In addition, the ß + IDA and IDA groups received iron supplementation for four weeks. We found no statistically significant correlation between hepcidin and GDF15 in any group, but a positive correlation was observed between hepcidin and ferritin. After iron supplementation, the routine blood parameters and iron metabolism parameters in the ß + IDA group were improved, and the hepcidin content was significantly increased. These results suggest that in pregnant women with beta-thalassaemia minor, hepcidin functions normally to maintain iron homeostasis, and that iron supplementation is effective and safe.

Hemoglobin life-threatening value (1.9 g/dl) in good general condition: a pediatric case-report.

BACKGROUND: We report a pediatric patient presenting in good general condition despite a hemoglobin value of 1,9 g/dL, which is normally regarded as life-threatening. CASE PRESENTATION: An African 5 years-old girl presented to our Emergency Department (ED) for worsening asthenia, within a clinical picture of good general condition. The hemoglobin value at admission was 1,9 g/dL. The subsequent diagnostic-therapeutic pathway highlighted the presence of two different causes, both well known to be responsible for chronic anemia (with slow reduction of hemoglobin values): iron deficiency anemia (IDA) due to a very low dietary intake of iron-rich foods, and homozygous sickle cell disease (HbSS). She received transfusions of packed red blood cells (overall 15 ml/kg) and subsequently intravenous iron preparations (total amount 200 mg) followed by oral iron supplements. The Hb value at discharge, 10 days after the admission, was 9.8 g/dL. CONCLUSIONS: When approaching a picture of severe anemia, we suggest pediatricians take into consideration clinical conditions rather than laboratory values and to take advantage of detailed anamnestic data in order to make the diagnosis.

Iron distribution in different tissues of homozygous Mask (msk/msk) mice and the effects of oral iron treatments.

Iron-refractory iron deficiency anemia (IRIDA) is an autosomal recessive disorder caused by genetic mutations on TMPRSS6 gene which encodes Matriptase2 (MT2). An altered MT2 cannot appropriately suppress hepatic BMP6/SMAD signaling in case of low iron, hence hepcidin excess blocks dietary iron absorption, leading to a form of anemia resistant to oral iron supplementation. In this study, using the IRIDA mouse model Mask, we characterized homozygous (msk/msk) compared to asymptomatic heterozygous (msk/wt) mice, assessing the major parameters of iron status in different organs, at different ages in both sexes. The effect of carbonyl iron diet was analyzed as control iron supplementation being used for many studies in mice. It resulted effective in both anemic control and msk/msk mice, as expected, even if there is no information about its mechanism of absorption. Then, we mainly compared two forms of oral iron supplement, largely used for humans: ferrous sulfate and Sucrosomial iron. In anemic control mice, the two oral formulations corrected hemoglobin levels from 11.40 ± 0.60 to 15.38 ± 1.71 g/dl in 2-4 weeks. Interestingly, in msk/msk mice, ferrous sulfate did not increase hemoglobin likely due to ferroportin/hepcidin-dependent absorption, whereas Sucrosomial iron increased it from 11.50 ± 0.60 to 13.53 ± 0.64 g/dl mainly in the first week followed by a minor increase at 4 weeks with a stable level of 13.30 ± 0.80 g/dl, probably because of alternative absorption. Thus, Sucrosomial iron, already used in other conditions of iron deficiency, may represent a promising option for oral iron supplementation in IRIDA patients.
