Abstract
BACKGROUND Anemia affects one-fourth of the world's population and is caused mostly by iron deficiency. Iron supplementation is the most essential strategy for preventing iron deficiency anemia. Conventional oral iron salts have many drawbacks such as poor absorption & bioavailability, and poor tolerability resulting in poor clinical outcomes. OBJECTIVE To compare the effectiveness and safety of ferrous ascorbate, ferrous fumarate, ferrous bis-glycinate, and Sucrosomial iron in the management of iron deficiency anemia. METHOD The study is a retrospective observational clinical study comprising 260 subjects with hemoglobin between 7-10 g/dl. The patients were divided into four groups I, II, III, and IV, and received ferrous fumarate, ferrous ascorbate, ferrous bis-glycinate, and Sucrosomial iron respectively. Hematological profile and iron store indices were measured at baseline and month 3. One-way ANOVA followed by Tukey multiple comparison test was used to assess statistical significance (P < 0.05) using GraphPad Prism V.9.3.1 software. RESULTS The observational study showed that hemoglobin levels were significantly increased in the ferrous ascorbate group (11.86 ± 0.09; P < 0.0001), ferrous fumarate group (11.72 ± 0.08; P < 0.0001), ferrous bis-glycinate group (11.69 ± 0.11; P = 0.0003) and Sucrosomial iron group (12.20 ± 0.1; P < 0.0001) compared to the baseline. The Sucrosomial iron-supplemented group showed significantly higher improvement in hemoglobin levels and serum ferritin levels compared to conventional oral iron salts (P < 0.05) with a better safety profile. CONCLUSION The Sucrosomial iron showed significantly higher improvement in hemoglobin levels and higher improvement in iron store indices parameters along with a good tolerability profile compared to other conventional oral iron salts.

Abstract
OBJECTIVES Post-stroke fatigue (PSF) is an experience characterized by an early feeling of exhaustion with fatigue, a lack of energy, and difficulty in exertion, both motor and cognitive. To counteract fatigue and limit its effects on activities of daily living, the use of vitamins and minerals is known in addition to the pharmacological approach. However, few studies have evaluated the effect of vitamin and mineral supplementation on fatigue management. SiderAL® Med is a food for special medical purposes with a complete formulation containing vitamins, sucrosomal minerals, copper and algal calcium. The aim of the study is to evaluate whether nutritional supplementation with SiderAL® Med improves the symptom of fatigue and motor and cognitive function in stroke patients. DESIGN This is a pilot, randomized study with a control group. SETTING Post-Acute Rehabilitation Unit of the Fondazione Policlinico "A. Gemelli" IRCCS. PARTICIPANTS Twenty-four patients with stroke outcomes, admitted to rehabilitation, were recruited and randomized into the experimental group (Sid-G) and the control group (CG). INTERVENTION The Sid-G patients, in association with the pharmacological and rehabilitation therapy foreseen during hospitalization, took SiderAL® Med, one sachet per day for 8 weeks, while the CG patients underwent only the pharmacological and rehabilitation therapy foreseen in the daily routine. MEASUREMENTS All patients were assessed at baseline (T0), after 4 weeks (T1), after 8 weeks (T2) and after 12 weeks (T3) for motor and cognitive fatigue, balance, walking, functional capacity, cognitive performance, autonomy, quality of life and body composition. RESULTS Both Sid-G and CG patients showed significant improvement on most rating scales between T0-T1-T2-T3 (p = 0.0001). When comparing the two groups, a statistically significant difference emerged in favor of Sid-G with regard to motor fatigue (p = 0.007), cognitive fatigue (p = 0.009) and total fatigue (p = 0.034); balance (p < 0.001), functional capacity (p < 0.001); cognitive performance (p = 0.004); bone mineral content (p = 0.005), lean mass (p = 0.005), total mass (p < 0.001) and percentage of fat mass (p = 0.039). CONCLUSION Nutritional supplementation with SiderAL® Med, in concert with intensive rehabilitation treatment, appears to be effective in managing fatigue and improving motor and cognitive performance and body composition, representing a valuable tool to associate with rehabilitation treatment in stroke patients.

Abstract
Anemia is a severe health issue that affects around one-third of the global population. Therefore, the present study aims to conduct a bibliometric analysis to investigate the research trends regarding advancements on iron formulations in treating iron deficiency anemia via oral or parenteral route. This study adopts thematic and bibliometric methods on existing research on novel iron formulations. It also provides perspective into the existing understanding on treatment strategies for iron deficiency anemia. This study is conducted on 543 papers on various ferrous and ferric formulations used in the treatment of iron deficiency anemia. The study period is from 1977 to 2022, and the papers are identified from the Scopus database. The bibliometric analysis was carried out using the R tool's Bibliometrix package. The study discusses performance analysis, including annual publications, geographic analysis, relevant affiliations, journal analysis, and citation analysis. In addition, the conceptual structure, including the co-occurrence network, thematic map, thematic evolution, intellectual structure highlighting co-citation analysis, and social structure depicting the collaboration network and collaboration world map, are presented. The results showed increased research on formulation strategies for the treatment of iron deficiency anemia from 2010 onwards. The top 5 contributing countries are the USA, Italy, India, Germany, and the UK, and peer-reviewed journals from the area of nutrition. The most trending areas of study are iron deficiency anemia in pregnancy, chronic kidney diseases, inflammatory bowel diseases, and various intravenous formulations used in its treatment. The authors from Europe collaborate the most with authors from other countries. The study concludes that a safer and more effective iron formulation is needed to reduce the prevalence of anemia. The findings of the study are helpful in advancing research on innovative formulations for treating iron deficiency anemia. The insights from the study are helpful to policymakers in designing specific health policies and investing more in research and development of novel formulations for the treatment of iron deficiency anemia.

Abstract
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.

Abstract
Celiac disease (CD) is a chronic autoimmune disorder characterized by an immune-mediated response to gluten, resulting in small intestinal mucosal damage. While gastrointestinal (GI) symptoms are commonly associated with CD, atypical presentations can pose diagnostic challenges, particularly when hematological abnormalities are the primary manifestation. We report a case of a 52-year-old female patient who presented with paraesthesia, numbness in her hands and feet, marked thinness, extreme thrombocytosis, severe anemia, and mild electrolyte imbalance. Physical examination was unremarkable, except for the notable thinness. GI symptoms were absent, and there was no family history of gastroenterological diseases. Diagnostic evaluations, including serological tests and duodenal biopsy, confirmed the diagnosis of CD with grade 4 Marsh 3C classification. This case emphasizes the significance of considering CD as a potential cause for atypical hematological manifestations, such as extreme thrombocytosis secondary to severe anemia. Prompt recognition and appropriate management, including adherence to a gluten-free diet, can lead to symptom improvement and resolution of hematological abnormalities. It is crucial for healthcare professionals to recognize and be familiar with these atypical presentations to promote early diagnosis and enhance patient outcomes.

Abstract
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.

Abstract
OBJECTIVES Anemia is one of the most common extraintestinal manifestations of pediatric inflammatory bowel disease (IBD). We aimed to evaluate the prevalence of anemia in children newly diagnosed with IBD and assess the efficacy and safety of oral iron therapy over a 12-month follow-up period. METHODS This single-center, retrospective, observational cohort study included all children newly diagnosed with IBD at the Pediatric Gastroenterology Unit of Sapienza University of Rome from May 2015 to May 2019 presenting with anemia. At baseline, demographic, clinical, laboratory data (hemoglobin, mean corpuscular volume, serum iron, ferritin, transferrin levels, erythrocyte sedimentation rate, and C-reactive protein), and treatment received, were recorded. Clinical and laboratory data, as well as anemia therapy and adverse events (AEs), were collected every 3 months during the 1-year follow-up. RESULTS Eighty-nine out of 140 patients newly diagnosed with IBD presented with anemia (64%); 13 were excluded due to incomplete follow-up, thus 76 were included [median age 12.7 (interquartile range 9.8-15), 25 (33%) Crohn disease, 51 (67%) ulcerative colitis]. All patients received sucrosomial iron (SI) alone or in combination with intravenous ferric carboxymaltose. Treatment with SI was effective in 67 (88%) patients at the end of follow-up [37 (48%) within 3 months], regardless of anemia severity at baseline. No serious AEs related to SI treatment were reported. CONCLUSIONS We confirmed a high prevalence of anemia at the time of the diagnosis of pediatric IBD. Our data suggest that SI is safe and effective, leading to anemia resolution in approximately half of the patients within 3 months.

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

Abstract
BACKGROUND Anemia is a common complication of severe forms of epidermolysis bullosa (EB). To date, there are no guidelines outlining best clinical practices to manage anemia in the EB population. The objective of this manuscript is to present the first consensus guidelines for the diagnosis and management of anemia in EB. RESULTS Due to the lack of high-quality evidence, a consensus methodology was followed. An initial survey exploring patient preferences, concerns and symptoms related to anemia was sent to EB patients and their family members. A second survey was distributed to EB experts and focused on screening, diagnosis, monitoring and management of anemia in the different types of EB. Information from these surveys was collated and used by the panel to generate 26 consensus statements. Consensus statements were sent to healthcare providers that care for EB patients through EB-Clinet. Statements that received more than 70% approval (completely agree/agree) were adopted. CONCLUSIONS The end result was a series of 6 recommendations which include 20 statements that will help guide management of anemia in EB patients. In patients with moderate to severe forms of EB, the minimum desirable level of Hb is 100 g/L. Treatment should be individualized. Dietary measures should be offered as part of management of anemia in all EB patients, oral iron supplementation should be used for mild anemia; while iron infusion is reserved for moderate to severe anemia, if Hb levels of > 80-100 g/L (8-10 g/dL) and symptomatic; and transfusion should be administered if Hb is < 80 g/L (8 g/dL) in adults and < 60 g/L (6 g/dL) in children.

Abstract
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.

Abstract
The WHO has recognised iron deficiency anaemia (IDA) as the most common nutritional deficiency in the world, with 30% of the population being affected with this condition. Although the most common causes of IDA are gastrointestinal bleeding and menstruation in women, decreased dietary iron and decreased iron absorption are also culpable causes. Patients with IDA should be treated with the aim of replenishing iron stores and returning the haemoglobin to a normal level. This has shown to improve quality of life, morbidity, prognosis in chronic disease and outcomes in pregnancy. Iron deficiency occurs in many chronic inflammatory conditions, including congestive cardiac failure, chronic kidney disease and inflammatory bowel disease. This article will provide an updated overview on diagnosis and management of IDA in patients with chronic conditions, preoperative and in pregnancy. We will discuss the benefits and limitations of oral versus intravenous iron replacement in each cohort, with an overview on cost analysis between the different iron formulations currently on the market.

Abstract
Iron deficiency is one of the most common nutritional deficiencies worldwide and is often treated with oral iron supplements. However, commonly used supplements, including those based on ferrous iron salts, are associated with gastrointestinal side effects and unfavorable changes in the intestinal microbiome. Sucrosomial® iron is a novel iron formulation that is effective at treating iron deficiency, and with fewer gastrointestinal side effects, yet its effect on the gut microbiome has not been examined previously. Thus, we treated mice for two weeks with diets containing either Sucrosomial® iron or ferrous sulfate as the sole iron source and examined bacterial communities in the intestine using 16S Microbial Profiling of DNA extracted from feces collected both prior to and following dietary treatment. Mice treated with Sucrosomial® iron showed an increase in Shannon diversity over the course of the study. This was associated with a decrease in the abundance of the phylum Proteobacteria, which contains many pathogenic species, and an increase in short chain fatty acid producing bacteria such as Lachnospiraceae, Oscillibacter and Faecalibaculum. None of these changes were observed in mice treated with ferrous sulfate. These results suggest that Sucrosomial® iron may have a beneficial effect on the intestinal microbiome when compared to ferrous sulfate and that this form of iron is a promising alternative to ferrous iron salts for the treatment of iron deficiency.

Abstract
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.

Abstract
Iron is an essential nutrient to life and is required for erythropoiesis, oxidative, metabolism, and enzymatic activities. It is a cofactor for mitochondrial respiratory chain enzymes, the citric acid cycle, and DNA synthesis, and it promotes the growth of immune system cells. Thus, iron deficiency (ID) leads to deleterious effects on the overall health of individuals, causing significant morbidity. Iron deficiency anemia (IDA) is the most recognized type of anemia in patients with celiac disease (CD) and may be present in over half of patients at the time of diagnosis. Folate and vitamin B12 malabsorption, nutritional deficiencies, inflammation, blood loss, development of refractory CD, and concomitant Heliobacter pylori infection are other causes of anemia in such patients. The decision to replenish iron stores and the route of administration (oral or intravenous) are controversial due, in part, to questions surrounding the optimal formulation and route of administration. This paper provides an algorithm based on the severity of symptoms; its impact on the health-related quality of life (HRQL); the tolerance and efficiency of oral iron; and other factors that predict a poor response to oral iron, such as the severity of histological damage, poor adherence to GFD, and blood loss due to mucosal lesions.

Abstract
Iron deficiency anemia (IDA) is a common manifestation of Inflammatory Bowel Disease (IBD). Oral iron supplements are the treatment of choice, but are not always well tolerated. Sucrosomial® iron (SI) may represent an alternative. This prospective study assessed the tolerability and effectiveness of SI, and quality of life (QoL) of IDA-IBD patients who were intolerant to oral iron salts. The study included 52 individuals treated with 1 capsule/day for 12 weeks. Tolerability was assessed through a gastrointestinal symptom severity questionnaire. Hemoglobin (Hb) levels and clinical symptoms of IDA were analyzed. QoL was assessed using IBDQ-9 and EuroQoL questionnaires. The percentage of patients with excellent/good health increased from 42.9% to 94.3%. Mean Hb concentration significantly increased at all follow-up visits (p < 0.05). Almost all participants (96.9%) were adherent to the study medication. Patients' QoL improved (IBDQ-9: from 60.9 to 65.5). Patients also improved in mobility (71.8% to 78.1%), usual activities (51.3% to 68.7%), pain/discomfort (41.0% to 53.1%), and extreme depression/anxiety problems (7.7% to 3.2%); they worsened in self-care (100% to 90.6%), but perceived an enhancement in their global health [EQ-VAS score: 61.9 (±26.1) to 66.9 (±20.3)]. SI was well tolerated and improved IDA symptoms, IBD activity, and patients' QoL. In conclusion, SI should be considered in IDA-IBD patients.

Abstract
Anemia is a global health problem affecting one-third of the world population, and half of the cases are due to iron deficiency (ID). Iron deficiency anemia (IDA) is the leading cause of disability in several countries. Although multiple mechanisms may coexist, ID and IDA causes can be classified as i) insufficient iron intake for the body requirement, ii) reduced absorption, and iii) blood losses. Oral iron represents the mainstay of IDA treatment. IDA is defined as "refractory" when the hematologic response after 4 to 6 weeks of treatment with oral iron (an increase of >=1 g/dL of Hb) is absent. The cause of iron-refractory anemia is usually acquired and frequently related to gastrointestinal pathologies, although a rare genetic form called iron-refractory iron deficiency anemia (IRIDA) exists. In some pathological circumstances, either genetic or acquired, hepcidin increases, limiting the absorption in the gut, remobilization, and recycling of iron, thereby reducing iron plasma levels. Indeed, conditions with high hepcidin levels are often under-recognized as iron refractory, leading to inappropriate and unsuccessful treatments. This review provides an overview of the iron refractory anemia underlying conditions, from gastrointestinal pathologies to hepcidin dysregulation and iatrogenic or provoked conditions, and the specific diagnostic and treatment approach.

Abstract
Anemia affects millions of patients with chronic kidney disease (CKD) and prompt iron supplementation can lead to reductions in the required dose of erythropoiesis-stimulating agents, thereby reducing medical costs. Oral and intravenous (IV) traditional iron preparations are considered far from ideal, primarily due to gastrointestinal intolerability and the potential risk of infusion reactions, respectively. Fortunately, the emergence of novel iron replacement therapies has engendered a paradigm shift in the treatment of iron deficiency anemia in patients with CKD. For example, oral ferric citrate is an efficacious and safe phosphate binder that increases iron stores to maintain hemoglobin levels. Additional benefits include reductions in fibroblast growth factor 23 levels and the activation of 1,25 dihydroxyvitamin D. The new-generation IV iron preparations ferumoxytol, iron isomaltoside 1000, and ferric carboxymaltose are characterized by a reduced risk of infusion reactions and are clinically well tolerated as a rapid high-dose infusion. In patients undergoing hemodialysis (HD), ferric pyrophosphate citrate (FPC) administered through dialysate enables the replacement of ongoing uremic and HD-related iron loss. FPC transports iron directly to transferrin, bypassing the reticuloendothelial system and avoiding iron sequestration. Moreover, this paper summarizes recent advancements of hypoxia-inducible factor prolyl hydroxylase inhibitors and future perspectives in renal anemia management.

Abstract
Celiac disease (CD) is an autoimmune disorder characterized by intolerance to dietary gluten in genetically predisposed subjects. Iron deficiency anemia (IDA) is a common sign in CD, being the only abnormality in approximately 40% of celiac patients. A multifactorial etiology leads to IDA in CD. The two main causes are the villous atrophy of the mucosa at the site of iron absorption (the duodenum) and the resulting inflammation, which triggers the mechanism that leads to the anemia of chronic disease. Until now, it has been unclear why some patients with CD continue to have IDA despite a careful gluten-free diet (GFD) and the normalization of villous atrophy. Furthermore, some celiac patients are refractory to oral iron supplementation despite the healing of the mucosa, and they thus require periodic intravenous iron administration. The Marsh classification evaluates the degree of inflammation and villous atrophy, but it does not assess the possible persistence of ultrastructural and molecular alterations in enterocytes. The latter was found in CD in remission after adopting a GFD and could be responsible for the persistently reduced absorption of iron and IDA. Even in non-celiac gluten sensitivity, anemia is present in 18.5-22% of patients and appears to be related to ultrastructural and molecular alterations in intestinal microvilli. It is possible that a genetic component may also play a role in IDA. In this review, we evaluate and discuss the main mechanisms of IDA in CD and the possible causes of its persistence after adopting a GFD, as well as their therapeutic implications.

Abstract
Simple Summary In most mammals, including humans, the need for iron increases rapidly in the last period of pregnancy. Therefore, in compliance with World Health Organization (WHO) recommendations, iron supplementation has become a standard procedure even in healthy pregnant women although it carries the risk of iron toxicity and dysregulation of systemic iron homeostasis. Due to physiological and genomic similarities between swine and humans, pigs constitute an useful animal model in nutritional studies during pregnancy. Here, healthy pregnant sows were supplemented with sucrosomial ferric pyrophosphate (SFP), a new non-heme iron formulation, to study its effect on their iron metabolism and that of their progeny. In particular, we aimed at verifying whether supplementation of pregnant sows with SFP will increase the level of low hepatic iron stores in newborn piglets. Results of our study show that SFP does not significantly alter neither systemic iron homeostasis in pregnant sows, nor hepatic iron stores in newborn piglets, which can be used during neonatal period for the maintenance of hematological status. We hypothesize that supplemental iron given orally to pregnant sows is poorly transferred across the placenta. Abstract Background: The similarities between swine and humans in physiological and genomic patterns, as well as significant correlation in size and anatomy, make pigs an useful animal model in nutritional studies during pregnancy. In humans and pigs iron needs exponentially increase during the last trimester of pregnancy, mainly due to increased red blood cell mass. Insufficient iron supply during gestation may be responsible for the occurrence of maternal iron deficiency anemia and decreased iron status in neonates. On the other hand, preventive iron supplementation of non-anemic mothers may be of potential risk due to iron toxicity. Several different regimens of iron supplementation have been applied during pregnancy. The majority of oral iron supplementations routinely applied to pregnant sows provide inorganic, non-heme iron compounds, which exhibit low bioavailability and intestinal side effects. The aim of this study was to check, using pig as an animal model, the effect of sucrosomial ferric pyrophosphate (SFP), a new non-heme iron formulation on maternal and neonate iron and hematological status, placental transport and pregnancy outcome; Methods: Fifteen non-anemic pregnant sows were recruited to the experiment at day 80 of pregnancy and randomized into the non-supplemented group (control; n = 5) and two groups receiving oral iron supplementation—sows given sucrosomial ferric pyrophosphate, 60 mg Fe/day (SFP; n = 5) (SiderAL®, Pisa, Italy) and sows given ferrous sulfate 60 mg Fe/day (Gambit, Kutno, Poland) (FeSO4; n = 5) up to delivery (around day 117). Biological samples were collected from maternal and piglet blood, placenta and piglet tissues. In addition, data on pregnancy outcome were recorded.; Results: Results of our study show that both iron supplements do not alter neither systemic iron homeostasis in pregnant sows nor their hematological status at the end of pregnancy. Moreover, we did not detect any changes of iron content in the milk and colostrum of iron supplemented sows in comparison to controls. Neonatal iron status of piglets from iron supplemented sows was not improved compared with the progeny of control females. No statistically significant differences were found in average piglets weight and number of piglets per litter between animals from experimental groups. The placental expression of iron transporters varied depending on the iron supplement.

Abstract
Anemia is a complication that affects a majority of individuals with advanced CKD. Although relative deficiency of erythropoietin production is the major driver of anemia in CKD, iron deficiency stands out among the mechanisms contributing to the impaired erythropoiesis in the setting of reduced kidney function. Iron deficiency plays a significant role in anemia in CKD. This may be due to a true paucity of iron stores (absolute iron deficiency) or a relative (functional) deficiency which prevents the use of available iron stores. Several risk factors contribute to absolute and functional iron deficiency in CKD, including blood losses, impaired iron absorption, and chronic inflammation. The traditional biomarkers used for the diagnosis of iron-deficiency anemia (IDA) in patients with CKD have limitations, leading to persistent challenges in the detection and monitoring of IDA in these patients. Here, we review the pathophysiology and available diagnostic tests for IDA in CKD, we discuss the literature that has informed the current practice guidelines for the treatment of IDA in CKD, and we summarize the available oral and intravenous (IV) iron formulations for the treatment of IDA in CKD. Two important issues are addressed, including the potential risks of a more liberal approach to iron supplementation as well as the potential risks and benefits of IV versus oral iron supplementation in patients with CKD.

Abstract
BACKGROUND Oral iron is recommended as first line treatment of anemia in non-dialysis chronic kidney disease (ND-CKD) patients. Sucrosomial® iron, a new generation oral iron with high absorption and bioavailability and a low incidence of side effects, has shown to be not inferior to intravenous (IV) iron in the replacement of iron deficiency anemia in patients with ND-CKD. Besides the clinical benefit, it is also important to determine the comparative total costs of oral versus IV iron administrations. The aim of this study was to perform a cost-minimization analysis of oral Sucrosomial iron, compared with IV iron gluconate from an Italian societal perspective. METHODS Cost analysis was performed on the 99 patients with ND-CKD and iron-deficiency anemia of the randomized trial by Pisani et al. Human and material resources utilization was recorded during each iron administration. According to study perspective, direct and indirect costs were considered. Costs for each resource unit were taken from official Italian sources. Probabilistic sensitivity analyses were carried out to test the robustness of the results. RESULTS The base case analysis showed an average cost/cycle per patient of € 111 for oral iron and € 1302 for IV iron. Thus, the potential saving was equal to € 1191 per patient/cycle. The sensitivity analysis showed that the most sensitive driver is the time loss by patient and caregivers for the therapy and related-care, followed by the minutes of nursing care and the number of kilometres travelled to reach the referral centre. DISCUSSION This study showed that oral Sucrosomial® iron could offer specific advantages in terms of potential savings, and allowed identifying some implications for future research. Such advantages still persist with the new single dose IV iron formulation available in the market, although to a lesser extent.

Abstract
The objectives of this scoping review were to identify and characterize studies examining nutrition assessment, interventions, and measures to monitor gluten-free diet (GFD) adherence/compliance in patients with celiac disease (CD). An electronic literature search of four databases (Cochrane Database for systematic reviews, CINAHL, Embase, and Ovid MEDLINE) was conducted to identify articles examining nutrition care in CD individuals. Except for narrative review, grey literature, and case study/report, all types of peer-reviewed articles published between January 2007 and August 2018 were eligible. There were a total of 10,823 records; 10,368 were excluded during the first round of screening due to irrelevancy and/or duplication. Of the 455 full-text articles that were assessed, 292 met the criteria and were included. Most of the studies were observational studies (n=212), followed by experimental trials (n=50), evidence-based practice guideline (EBPG)/report/statement (n=16), and systematic review (SR) (n=14). Nine original studies examined assessment, focusing mainly on different tools/ways to assess GFD adherence. The majority of the included original articles (n=235) were in the nutrition intervention category with GFD, oats, and prebiotics/probiotics as the top-three most studied interventions. There were eight SRs on GFD and five on oats. One SR and 21 original studies investigated the effectiveness of different measures to monitor GFD adherence/compliance. Although recent CD EBPGs were identified, different methods with varying levels of rigor, in terms of literature search and assessment of evidence strength, were used. Based on this scoping review, interventions focused on gluten-free diet and oats have been significantly covered by either SRs or EBPGs. Studies related to prebiotics/probiotics and education program/counseling focused interventions, as well as assessment, in CD patients have increased in recent years. Thus, it might be beneficial to conduct SRs/EBPGs focused on these topics to guide practitioners.

Abstract
Celiac disease (CD) is a multisystemic disorder with different clinical expressions, from malabsorption with diarrhea, anemia, and nutritional compromise to extraintestinal manifestations. Anemia might be the only clinical expression of the disease, and iron deficiency anemia is considered one of the most frequent extraintestinal clinical manifestations of CD. Therefore, CD should be suspected in the presence of anemia without a known etiology. Assessment of tissue anti-transglutaminase and anti-endomysial antibodies are indicated in these cases and, if positive, digestive endoscopy and intestinal biopsy should be performed. Anemia in CD has a multifactorial pathogenesis and, although it is frequently a consequence of iron deficiency, it can be caused by deficiencies of folate or vitamin B12, or by blood loss or by its association with inflammatory bowel disease (IBD) or other associated diseases. The association between CD and IBD should be considered during anemia treatment in patients with IBD, because the similarity of symptoms could delay the diagnosis. Vitamin B12 deficiency is common in CD and may be responsible for anemia and peripheral myeloneuropathy. Folate deficiency is a well-known cause of anemia in adults, but there is little information in children with CD; it is still unknown if anemia is a symptom of the most typical CD in adult patients either by predisposition due to the fact of age or because biochemical and clinical manifestations take longer to appear.

Abstract
INTRODUCTION This systematic review and meta-analysis aims to explore the influence of ferumoxytol versus placebo on iron deficiency anemia. METHODS We search for randomized controlled trials (RCTs) assessing the effect of ferumoxytol on iron deficiency anemia on PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases. This meta-analysis is performed using the random-effects model. RESULTS Four RCTs are included in the meta-analysis. Compared with the control group for iron deficiency anemia, intravenous ferumoxytol can significantly improve the proportion of patients with a ≥20 g/L hemoglobin (Hb) increase (RR = 18.43; 95% CI = 7.29-46.57; p < 0.00001), the proportion of patients with an Hb level ≥120 g/L (RR = 18.55; 95% CI = 8.66-39.72; p < 0.00001), transferrin saturation (mean difference = 11.08; 95% CI = 9.86-12.31; p < 0.00001) and FACIT-fatigue score (mean difference = 4.60; 95% CI = 3.21-6.00; p < 0.00001), but has no remarkable influence on adverse events (RR = 1.33; 95% CI = 0.84-2.10; p = 0.22), serious adverse events (RR = 1.22; 95% CI = 0.74-2.02; p = 0.44), and death (RR = 0.32; 95% CI = 0.05-1.95; p = 0.22). CONCLUSIONS Intravenous ferumoxytol can provide the important benefits for iron deficiency anemia.

Abstract
Iron deficiency anemia (IDA) is a frequent complication of chronic kidney disease (CKD) and is associated with adverse outcomes in these patients. Patients with CKD and IDA remain largely undertreated. Conventional oral iron agents are insufficiently effective due to poor absorption and cause gastrointestinal side effects; thus, novel oral iron preparations are needed. This article covers current treatment guidelines for patients with anemia and CKD and clinical trial data for iron-repletion agents currently in use, as well as for novel oral iron therapies in development. Ferric citrate, a novel oral iron-repletion agent approved for patients with non-dialysis-dependent CKD and IDA, demonstrated improvements in hemoglobin levels and iron parameters, with good tolerability in patients with non-dialysis-dependent CKD. When used as a phosphate binder, ferric citrate also improves hemoglobin and iron parameters in dialysis-dependent CKD, but additional trials are needed to evaluate its efficacy as an iron-repletion agent in this setting. Other novel oral iron preparations in development for IDA in patients with CKD include ferric maltol, which is approved in Europe and the United States for IDA in adult patients, and sucrosomial iron, which has been evaluated in IDA associated with CKD and several other clinical settings.

Abstract
Iron deficiency (ID) is usually treated with oral iron salts, but up to 50% of patients complain of gastrointestinal side effects, leading to reduced treatment compliance. Intravenous (IV) iron formulations are increasingly safer, but there is still a risk of infusion and hypersensitivity reactions and the need for a venous access and infusion monitoring. Sucrosomial® iron (SI) is an innovative oral iron formulation in which ferric pyrophosphate is protected by a phospholipid bilayer plus a sucrester matrix (sucrosome), which is absorbed through para-cellular and trans-cellular routes (M cells). This confers SI unique structural, physicochemical and pharmacokinetic characteristics, together with high iron bioavailability and excellent gastrointestinal tolerance. The analysis of available evidence supports oral SI iron as a valid option for ID treatment, which is more efficacious and better tolerated than oral iron salts. SI has also demonstrated similar effectiveness, with lower risks, in patients usually receiving IV iron (e.g., chronic kidney disease, cancer, bariatric surgery). Thus, oral SI emerges as a most valuable first option for treating ID, even more for subjects with intolerance to or inefficacy of iron salts. Moreover, SI should be also considered as an alternative to IV iron for initial and/or maintenance treatment in different patient populations.

Abstract
Sucrosomial® Iron is a recently developed formulation to treat iron deficiency based on ferric pyrophosphate covered by a matrix of phospholipids plus sucrose esters of fatty acids. Previous data indicated that Sucrosomial® Iron is efficiently absorbed by iron-deficient subjects, even at low dosage, and without side effects. Its structural properties may suggest that it is absorbed by an intestinal pathway which is different to the one used by ionic iron. Although, studies in vitro showed that Sucrosomial® Iron is readily absorbed, no animal models have been established to study this important aspect. To this aim, we induced iron deficient anemia in mice by feeding them with a low-iron diet, and then we treated them with either Sucrosomial® Iron or sulfate iron by gavage for up to two weeks. Both iron formulations corrected anemia and restored iron stores in a two-week period, but with different kinetics. Ferrous Sulfate was more efficient during the first week and Sucrosomial® Iron in the second week. Of note, when given at the same concentrations, Ferrous Sulfate induced the expression of hepcidin and four different inflammatory markers (Socs3, Saa1, IL6 and CRP), while Sucrosomial® Iron did not. We conclude that anemic mice are interesting models to study the absorption of oral iron, and that Sucrosomial® Iron is to be preferred over Ferrous Sulfate because of similar absorption but without inducing an inflammatory response.
