    Post-transplant anaemia remains a common problem after kidney transplantation, with an incidence ranging from nearly 80% at day 0 to about 25% at 1 year. It has been associated with poor graft outcome, and recently has also been shown to be associated with increased mortality.Our transplant unit routinely administers oral iron supplements to renal transplant recipients but this is frequently accompanied by side effects, mainly gastrointestinal intolerance. Intravenous iron is frequently administered to dialysis patients and we sought to investigate this mode of administration in transplant recipients after noticing less anaemia in several patients who had received intravenous iron just prior to being called in for transplantation. This study is a single-centre, prospective, open-label, randomised, controlled trial of oral versus intravenous iron supplements in renal transplant recipients and aims to recruit approximately 100 patients over a 12-month period. Patients will be randomised to receive a single dose of 500 mg iron polymaltose (intravenous iron group) or 2 ferrous sulphate slow-release tablets daily (oral iron group). The primary outcome is time to normalisation of haemoglobin post-transplant. Prospective power calculations have indicated that a minimum of 48 patients in each group would have to be followed up for 3 months in order to have a 90% probability of detecting a halving of the time to correction of haemoglobin levels to > or =110 g/l in iron-treated patients, assuming an alpha of 0.05. All eligible adult patients undergoing renal transplantation at the Princess Alexandra Hospital will be offered participation in the trial. Exclusion criteria will include iron overload (transferrin saturation >50% or ferritin >800 microg/l), or previous intolerance of either oral or intravenous iron supplements. If the trial shows a reduction in the time to correction of anaemia with intravenous iron or less side effects than oral iron, then intravenous iron may

    A European reassessment has led to identical changes in the summaries of product characteristics (SPCs) for all intravenous iron-containing products: the risk of serious adverse effects is now highlighted, underlining the fact that intravenous iron-containing products should only be used when the benefits clearly outweigh the harms. Unfortunately, iron dextran still remains on the market despite a higher risk of hypersensitivity reactions than with iron sucrose.

  8. Intravenous Iron Carboxymaltose as a Potential Therapeutic in Anemia of Inflammation.

    Directory of Open Access Journals (Sweden)

    Niklas Lofruthe

    Full Text Available Intravenous iron supplementation is an effective therapy in iron deficiency anemia (IDA, but controversial in anemia of inflammation (AI. Unbound iron can be used by bacteria and viruses for their replication and enhance the inflammatory response. Nowadays available high molecular weight iron complexes for intravenous iron substitution, such as ferric carboxymaltose, might be useful in AI, as these pharmaceuticals deliver low doses of free iron over a prolonged period of time. We tested the effects of intravenous iron carboxymaltose in murine AI: Wild-type mice were exposed to the heat-killed Brucella abortus (BA model and treated with or without high molecular weight intravenous iron. 4h after BA injection followed by 2h after intravenous iron treatment, inflammatory cytokines were upregulated by BA, but not enhanced by iron treatment. In long term experiments, mice were fed a regular or an iron deficient diet and then treated with intravenous iron or saline 14 days after BA injection. Iron treatment in mice with BA-induced AI was effective 24h after iron administration. In contrast, mice with IDA (on iron deficiency diet prior to BA-IA required 7d to recover from AI. In these experiments, inflammatory markers were not further induced in iron-treated compared to vehicle-treated BA-injected mice. These results demonstrate that intravenous iron supplementation effectively treated the murine BA-induced AI without further enhancement of the inflammatory response. Studies in humans have to reveal treatment options for AI in patients.

    Iron deficiency anaemia (IDA) is a global public health problem. Treatment with the standard of care ferrous iron salts may be poorly tolerated, leading to non-compliance and ineffective correction of IDA. Employing supplements with higher bioavailability might permit lower doses of iron to be used with fewer side effects, thus improving treatment efficacy. Here, we compared the iron bioavailability of ferrous sulphate tablets with alternative commercial iron products, including three liquid-based supplements. Iron bioavailability was measured using Caco-2 cells with ferritin formation as a surrogate marker for iron uptake. Statistical analysis was performed using one-way ANOVA followed by either Dunnett's or Tukey's multiple comparisons tests. Spatone Apple(®) (a naturally iron-rich mineral water with added ascorbate) and Iron Vital F(®) (a synthetic liquid iron supplement) had the highest iron bioavailability. There was no statistical difference between iron uptake from ferrous sulphate tablets, Spatone(®) (naturally iron-rich mineral water alone) and Pregnacare Original(®) (a multimineral/multivitamin tablet). In our in vitro model, naturally iron-rich mineral waters and synthetic liquid iron formulations have equivalent or better bioavailability compared with ferrous iron sulphate tablets. If these results are confirmed in vivo, this would mean that at-risk groups of IDA could be offered a greater choice of more bioavailable and potentially better tolerated iron preparations.

  11. Intravenous ferric carboxymaltose for the treatment of iron deficiency anemia

    2015-12-01

    Full Text Available ABSTRACT Nutritional iron deficiency anemia is the most common deficiency disorder, affecting more than two billion people worldwide. Oral iron supplementation is usually the first choice for the treatment of iron deficiency anemia, but in many conditions, oral iron is less than ideal mainly because of gastrointestinal adverse events and the long course needed to treat the disease and replenish body iron stores. Intravenous iron compounds consist of an iron oxyhydroxide core, which is surrounded by a carbohydrate shell made of polymers such as dextran, sucrose or gluconate. The first iron product for intravenous use was the high molecular weight iron dextran. However, dextran-containing intravenous iron preparations are associated with an elevated risk of anaphylactic reactions, which made physicians reluctant to use intravenous iron for the treatment of iron deficiency anemia over many years. Intravenous ferric carboxymaltose is a stable complex with the advantage of being non- dextran-containing and a very low immunogenic potential and therefore not predisposed to anaphylactic reactions. Its properties permit the administration of large doses (15 mg/kg; maximum of 1000 mg/infusion in a single and rapid session (15-minute infusion without the requirement of a test dose. The purpose of this review is to discuss some pertinent issues in relation to the history, pharmacology, administration, efficacy, and safety profile of ferric carboxymaltose in the treatment of patients with iron deficiency anemia.

    Erythropoiesis-stimulating agents (ESAs) are often used in treatment of patients with chemotherapy-induced anemia. Many studies have demonstrated an improved hemoglobin (Hb) response when ESA is combined with intravenous iron supplementation and a higher effectiveness of intravenous iron over traditional oral iron formulations. A new formulation of oral sucrosomial iron featuring an increased bioavailability compared to traditional oral formulations has recently become available and could provide a valid alternative to those by intravenous (IV) route. Our study evaluated the performance of sucrosomial iron versus intravenous iron in increasing hemoglobin in anemic cancer patients receiving chemotherapy and darbepoetin alfa, as well as safety, need of transfusion, and quality of life (QoL). The present study considered a cohort of 64 patients with chemotherapy-related anemia (Hb >8 g/dL iron deficiency, scheduled to receive chemotherapy and darbepoetin. All patients received darbepoetin alfa 500 mcg once every 3 weeks and were randomly assigned to receive 8 weeks of IV ferric gluconate 125 mg weekly or oral sucrosomial iron 30 mg daily. The primary endpoint was to demonstrate the performance of oral sucrosomial iron in improving Hb response, compared to intravenous iron. The Hb response was defined as the Hb increase ≥2 g/dL from baseline or the attainment Hb ≥ 12 g/dL. There was no difference in the Hb response rate between the two treatment arms. Seventy one percent of patients treated with IV iron achieved an erythropoietic response, compared to 70% of patients treated with oral iron. By conventional criteria, this difference is considered to be not statistically significant. There were also no differences in the proportion of patients requiring red blood cell transfusions and changes in QoL. Sucrosomial oral iron was better tolerated. In cancer patients with chemotherapy-related anemia receiving darbepoetin alfa, sucrosomial oral iron provides

    To improve the iron status of infants an effort was made to increase the iron content of complementary foods by adding 12.5 mg of elemental iron to the meal in the form of micro-encapsulated ferrous fumarate coated with a lipid. The contents of the packet were sprinkled directly on to infant foods. Relative absorption of iron from this supplement was determined in a prospective randomized study with 39 infants (mean age 33.6 +/- 5.2 weeks) with initial hemoglobin values greater than 100 g/L. They were fed two complementary foods (rice-based and wheat-based) in which the supplement labeled with stable isotopes of iron 57Fe and 58Fe was incorporated. The erythrocyte iron incorporation was measured in the blood by inductively coupled plasma mass spectrophotometry. The incorporation of iron was significantly higher 11.9% p sprinkles has proved to be efficacious in increasing the available iron intake of the infants.

    Intravenous iron formulations are a class of complex drugs that are commonly used to treat a wide variety of disease states associated with iron deficiency and anemia. Venofer® (iron-sucrose) is one of the most frequently used formulations, with more than 90% of dialysis patients in the United States receiving this formulation. Emerging data from global markets outside the United States, where many iron-sucrose similars or copies are available, have shown that these formulations may have safety and efficacy profiles that differ from the reference listed drug. This may be attributable to uncharacterized differences in physicochemical characteristics and/or differences in labile iron release. As bioequivalence evaluation guidance evolves, clinicians should be educated on these potential clinical issues before a switch to the generic formulation is made in the clinical setting. © 2017 New York Academy of Sciences.

    Intravenous iron sucrose and oral iron therapy are the main therapies for iron deficiency anaemia (IDA), but there is still a debate regarding their efficacy and especially as to which one is the best choice during pregnancy. A meta-analysis of randomised controlled trials comparing patients treated with intravenous iron sucrose (intravenous group) with those treated with oral iron (oral group) for IDA during pregnancy was performed. The primary outcomes of interest were mean maternal haemoglobin and serum ferritin levels at the end of treatment. Secondary outcomes were treatment-related adverse events and foetal birth weight. Six randomised controlled trials, involving a total of 576 women, were included in the present review. Significant increases in haemoglobin [mean difference (MD), 0.85; 95% confidence interval (CI), 0.31-1.39; p = 0.002] and ferritin levels (MD, 63.32; 95% CI, 39.46-87.18; p < 0.00001) were observed in the intravenous group. Compared with the oral group, there were fewer adverse events in the intravenous group (risk ratio, 0.50; 95% CI, 0.34-0.73; p = 0.0003). There was no significant difference in birth weight between the two groups. For pregnant women who could not tolerate the side effects of oral treatment or required a rapid replacement of iron stores, intravenous iron sucrose was associated with fewer adverse events and was more effective than regular oral iron therapy. © 2015 S.

    Anemia affects up to 42% of gravidas. Neonatal iron deficiency is associated with low birth weight, delayed growth and development, and increased cognitive and behavioral abnormalities. While oral iron is convenient, up to 70% report significant gastrointestinal toxicity. Intravenous iron formulations allowing replacement in one visit with favorable side-effect profiles decrease rates of anemia with improved hemoglobin responses and maternal fetal outcomes. Seventy-four oral iron-intolerant, second- and third-trimester iron-deficient gravidas were questioned for oral iron intolerance and treated with intravenous iron. All received 1000 mg of low-molecular-weight iron dextran in 250 mL normal saline. Fifteen minutes after a test dose, the remainder was infused over the balance of 1 hour. Subjects were called at 1, 2, and 7 days to assess delayed reactions. Four weeks postinfusion or postpartum, hemoglobin levels and iron parameters were measured. Paired t test was used for hemoglobin and iron; 58/73 women were questioned about interval growth and development of their babies. Seventy-three of 74 enrolled subjects completed treatment.

  7. Iron supplementation: overcoming technical and practical barriers.

    Iron supplementation is probably the best available option to effectively address iron deficiency in pregnant women and young children because it can be targeted specifically to these high-risk groups. However, technical and practical barriers exist: limited information on the effectiveness of supplementation interventions, side effects that affect compliance, and supply/distribution constraints. An innovative approach to addressing these constraints is the use of sprinkles of powdered, microencapsulated ferrous fumarate that can be added directly to any semi-liquid food without changing their taste or consistency. This technique has been tested in initial trials in Ghana and found to be as effective as iron drops. Another approach to improve the effectiveness of iron interventions is through information, education and communication (IEC) programs. These interventions can help modify consumer behavior in some cases, but in some countries, geographic location, variations in language and population size can make the cost of IEC programs very high. IEC strategies in Indonesia aimed at increasing demand for iron supplements by systematic dissemination of specific messages, improving the quality and variety of tablets, increasing the availability and access to supplements by engaging the commercial sector, enrolling traditional birth attendants and other community volunteers in selling supplements. Key issues to be addressed include clarifying optimal starting points and duration of supplementation interventions--based on individual status or population prevalence, defining hemoglobin and ferritin cutoffs at which treatment should be instigated and evaluating the effectiveness of intermittent supplementation with multiple micronutrients.

    Background Iron and folic acid supplementation has been the preferred intervention to improve iron stores and prevent anaemia among pregnant women, and it may also improve other maternal and birth outcomes. Objectives To assess the effects of daily oral iron supplements for pregnant women, either alone or in conjunction with folic acid, or with other vitamins and minerals as a public health intervention. Search methods We searched the Cochrane Pregnancy and Childbirth Group’s Trials Register (2 July 2012). We also searched the WHO International Clinical Trials Registry Platform (ICTRP) (2 July 2012) and contacted relevant organisations for the identification of ongoing and unpublished studies. Selection criteria Randomised or quasi-randomised trials evaluating the effects of oral preventive supplementation with daily iron, iron + folic acid or iron + other vitamins and minerals during pregnancy. Data collection and analysis We assessed the methodological quality of trials using standard Cochrane criteria. Two review authors independently assessed trial eligibility, extracted data and conducted checks for accuracy. Main results We included 60 trials. Forty-three trials, involving more than 27,402 women, contributed data and compared the effects of daily oral supplements containing iron versus no iron or placebo. Overall, women taking iron supplements were less likely to have low birthweight newborns (below 2500 g) compared with controls (8.4% versus 10.2%, average risk ratio (RR) 0.81; 95% confidence interval (CI) 0.68 to 0.97, 11 trials, 8480 women) and mean birthweight was 30.81 g greater for those infants whose mothers received iron during pregnancy (average mean difference (MD) 30.81; 95% CI 5.94 to 55.68, 14 trials, 9385 women). Preventive iron supplementation reduced the risk of maternal anaemia at term by 70% (RR 0.30; 95% CI 0.19 to 0.46, 14 trials, 2199 women) and iron deficiency at term by 57% (RR 0.43; 95% CI 0.27 to 0.66, seven trials, 1256 women

This clinic was set up to provide diagnosis and treatment, and to coordinate investigative procedures, where necessary, into the underlying causes of anemia. Initially piloted with anemic preoperative orthopedic patients, the clinic now treats a wide range of conditions, deriving from both internal and external referrals. Treatment includes dietary advice, supplementation with iron, vitamin B12 and folate, and blood transfusion. Most patients at the RAAC need iron replacement, the majority of which require intravenous (IV iron. Therefore the first-line IV iron-administration protocol is carefully considered to ensure viability of the service and patient satisfaction. Four IV irons available in the UK are discussed, with explanation of the benefits and drawbacks of each product and the reasoning behind the IV iron choice at different stages of the RAAC's development. Costs to the service, affected by IV iron price and administration regimen, are considered, as well as the product's contraindications. Finally, the authors reflect on the success of the RAAC and how it has improved patients' quality-of-treatment experience, in addition to benefiting the hospital and National Health Service in achieving specific health-care mandates and directives. Drawing from the authors' experiences, recommendations are given to assist others in setting up and providing a successful rapid-access anemia service or similar facility.Keywords: hemoglobin, iron deficiency, ferric carboxymaltose, iron sucrose, iron dextran, iron isomaltoside

    Full Text Available Professional societies have published recommendations for iron dosing of preterm neonates, but differences exist between guidelines. To help develop standardized guidelines, we performed a 10-year analysis of iron dosing in groups at risk for iron deficiency: IDM (infants of diabetic mothers, SGA (small for gestational age, and VLBW premature neonates (very low birth weight, <1500 g. We analyzed iron dosing after red cell transfusions and erythropoiesis-stimulating agents (ESA. Of IDM, 11.8% received iron in the hospital; 9.8% of SGA and 27.1% of VLBW neonates received iron. Twenty percent of those who received iron had it started by day 14; 63% by 1 month. Supplemental iron was stopped after red cell transfusions in 73% of neonates receiving iron. An ESA was administered to 1677, of which 33% received iron within 3 days. This marked variation indicates that a consistent approach is needed, and using this report and a literature review, we standardized our iron-dosing guidelines.

    Oral iron-replacement therapy is the mainstay of treatment for iron-deficiency anemia, but it is often poorly tolerated or ineffective. Hemoglobin response at day 14 of oral iron may be useful in assessing whether and when to transition patients from oral to intravenous (IV) iron. Pooled data from 5 randomized trials were analyzed to compare oral and IV iron-replacement therapy for iron-deficiency anemia. Treatment criteria and assignment to oral versus IV iron were defined per protocol; this analysis included only subjects receiving oral iron. Responders were subjects with ≥1.0-g/dL increases in hemoglobin at day 14, and nonresponders were those with smaller increases. Demographic and clinical characteristics were evaluated for association with hemoglobin response at multiple timepoints. Most subjects (72.8%) were classified as responders. The proportion of subjects with hemoglobin increases ≥1.0, ≥2.0, and ≥3.0 g/dL was greatest among those with postpartum anemia, intermediate among those with heavy uterine bleeding or gastrointestinal-related causes of anemia, and lowest among those with other causes; this proportion was also significantly greater among responders than nonresponders. A ≥1.0-g/dL increase in hemoglobin on day 14 most accurately predicted satisfactory overall hemoglobin response to oral iron on day 42/56 (sensitivity 90.1%; specificity 79.3%; positive and negative predictive values of 92.9% and 72.7%, respectively). Iron-replacement therapy improved quality of life and reduced fatigue. Hemoglobin responses <1.0 g/dL at day 14 of oral iron identify subjects with iron-deficiency anemia who should be transitioned to IV iron supplementation. Copyright © 2017 Elsevier Inc.

    Full Text Available Introduction. Parenteral iron formulations are frequently used to correct iron deficiency anemia (IDA and iron deficiency (ID. Intravenous formulation efficacy on ferritin and hemoglobin level improvement is greater than that of oral formulations while they are associated with lower gastrointestinal side effects. Ferric carboxymaltose- (FCM- related hypophosphatemia is frequent and appears without clinical significance. The aim of this study was to assess the prevalence, duration, and potential consequences of hypophosphatemia after iron injection. Patients and Methods. The medical records of all patients who underwent parenteral iron injection between 2012 and 2014 were retrospectively reviewed. Pre- and postinjection hemoglobin, ferritin, plasma phosphate, creatinine, and vitamin D levels were assessed. Patients who developed moderate (range: 0.32–0.80 mmol/L or severe (<0.32 mmol/L hypophosphatemia were questioned for symptoms. Results. During the study period, 234 patients received iron preparations but 104 were excluded because of missing data. Among the 130 patients included, 52 received iron sucrose (FS and 78 FCM formulations. Among FS-treated patients, 22% developed hypophosphatemia versus 51% of FCM-treated patients, including 13% who developed profound hypophosphatemia. Hypophosphatemia severity correlated with the dose of FCM (p=0.04 but not with the initial ferritin, hemoglobin, or vitamin D level. Mean hypophosphatemia duration was 6 months. No immediate clinical consequence was found except for persistent fatigue despite anemia correction in some patients. Conclusions. Hypophosphatemia is frequent after parenteral FCM injection and may have clinical consequences, including persistent fatigue. Further studies of chronic hypophosphatemia long-term consequences, especially bone assessments, are needed.

    Iron-deficiency anemia is the most common hematologic problem in the world. Although oral iron is often viewed as front-line therapy, extensive published evidence has accumulated that IV iron is superior, in both efficacy and safety, to oral iron in many clinical situations and should be introduced much sooner in the treatment paradigm of iron-deficient patients. In this chapter, we will review the formulations of IV iron that allow total complete replacement doses in 1 or 2 sessions including practical tips for administration. We realize safety concerns abound and therefore will analyze evidence based overstated concerns regarding serious adverse events highlighting unnecessary interventions for minor, self-limiting infusion reactions, which infrequently occur with intravenous iron administration. Recent data for the use of IV iron in a variety of clinic situations will be reviewed including women with heavy uterine bleeding, pregnancy, bariatric surgery, inflammatory bowel disease, and restless legs syndrome. Briefly discussed is the new frontier of IV iron's use in the prevention of acute (high altitude) mountain sickness. It is clear that in many clinical situations IV iron is a new and improved standard of care offering advantages over oral iron in efficacy, toxicity, and convenience to patients and health care providers. © 2016 by The American Society of Hematology.

    Full Text Available Objective. To provide clinicians with evidence-based guidance for iron therapy dosing in patients with iron deficiency anemia (IDA, we conducted a study examining the benefits of a higher cumulative dose of intravenous (IV iron than what is typically administered. Methods. We first individually analyzed 5 clinical studies, averaging the total iron deficit across all patients utilizing a modified Ganzoni formula; we then similarly analyzed 2 larger clinical studies. For the second of the larger studies (Study 7, we also compared the efficacy and retreatment requirements of a cumulative dose of 1500 mg ferric carboxymaltose (FCM to 1000 mg iron sucrose (IS. Results. The average iron deficit was calculated to be 1531 mg for patients in Studies 1–5 and 1392 mg for patients in Studies 6-7. The percentage of patients who were retreated with IV iron between Days 56 and 90 was significantly (p<0.001 lower (5.6% in the 1500 mg group, compared to the 1000 mg group (11.1%. Conclusions. Our data suggests that a total cumulative dose of 1000 mg of IV iron may be insufficient for iron repletion in a majority of patients with IDA and a dose of 1500 mg is closer to the actual iron deficit in these patients.

    Background Anaemia is a frequent condition during pregnancy, particularly among women from developing countries who have insufficient iron intake to meet increased iron needs of both the mother and the fetus. Traditionally, gestational anaemia has been prevented with the provision of daily iron supplements throughout pregnancy, but adherence to this regimen due to side effects, interrupted supply of the supplements, and concerns about safety among women with an adequate iron intake, have limited the use of this intervention. Intermittent (i.e. one, two or three times a week on non-consecutive days) supplementation with iron alone or in combination with folic acid or other vitamins and minerals has recently been proposed as an alternative to daily supplementation. Objectives To assess the benefits and harms of intermittent supplementation with iron alone or in combination with folic acid or other vitamins and minerals to pregnant women on neonatal and pregnancy outcomes. Search methods We searched the Cochrane Pregnancy and Childbirth Group’s Trials Register (23 March 2012). We also searched the WHO International Clinical Trials Registry Platform (ICTRP) for ongoing studies and contacted relevant organisations for the identification of ongoing and unpublished studies (23 March 2012). Selection criteria Randomised or quasi-randomised trials. Data collection and analysis We assessed the methodological quality of trials using standard Cochrane criteria. Two review authors independently assessed trial eligibility, extracted data and conducted checks for accuracy. Main results This review includes 21 trials from 13 different countries, but only 18 trials (with 4072 women) reported on our outcomes of interest and contributed data to the review. All of these studies compared daily versus intermittent iron supplementation. Three studies provided iron alone, 12 iron+folic acid and three more iron plus multiple vitamins and minerals. Their methodological quality was mixed

    Early iron supplementation in women with sufficient reserves could provoke iron excess resulting in haemoconcentration and low infant birth weight (IBW). To clarify the influence of early iron supplementation on maternal iron status and the IBW, taking into account pre-pregnancy iron deposits. Longitudinal, prospective study. Healthy women volunteers (n=82) intending to become pregnant. Women were grouped as a function of their pre-pregnancy (low or present) iron stores (serum ferritin (SF)supplementation during pregnancy; "early" (supplementation with iron was 140.7mg/d and the mean of late supplementation was 99.01mg/d. Early supplementation improves the biochemical status of the mother and does not provoke a significant increase in haemoconcentration relative to late supplementation independently of the pre-pregnancy iron levels. Supplemental iron had a positive effect on birth weight among women with pre-pregnancy low iron stores (β=4.37; SE=1.8; p=0.038) and did not affect birth weight among women with present iron stores (β=-0.008; SE=3.03; p=0.998). Early iron supplementation with doses ~100mg/d improves the biochemical status of the mother independently of her pre-pregnancy iron status. Supplementation with iron improves newborn birth weight in those women who start pregnancy with iron deficiency, and makes no significant difference to those women who are not iron deficient.

    Preterm infants are at risk of exhausting their body iron stores much earlier than healthy term newborns. It is widespread practice to give enteral iron supplementation to preterm and low birth weight infants to prevent iron deficiency anaemia. However, it is unclear whether supplementing preterm and low birth weight infants with iron improves growth and neurodevelopment. It is suspected that excess exogenous iron can contribute to oxidative injury in preterm babies, causing or exacerbating conditions such as necrotising enterocolitis and retinopathy of prematurity. Additionally, the optimal dose and timing of commencement and cessation of iron supplementation are uncertain. To evaluate the effect of prophylactic enteral iron supplementation on growth and neurodevelopmental outcomes in preterm and low birth weight infants. The secondary objectives were to determine whether iron supplementation results in improved haematological parameters and prevents other causes of morbidity and mortality. We used the standard search strategy of the Cochrane Neonatal Review Group. We searched Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 8), MEDLINE (1951 to August 2011), CINAHL (1982 to August 2011) and conference proceedings and previous reviews. Randomised controlled trials (RCTs) and quasi-randomised trials that compared enteral iron supplementation with no iron supplementation, or different regimens of enteral iron supplementation in preterm or low birth weight infants or both. We extracted data using the standard methods of the Cochrane Neonatal Review Group. Both review authors separately evaluated trial quality and data extraction. We synthesised data using risk ratios (RRs), risk differences (RDs) and weighted mean differences (WMDs). Where data about the methodology and results or both were lacking, we made an attempt to contact the study authors for further information. We included twenty-six studies (2726 infants) in the

    2002-01-01

    Full Text Available The purpose of the present study was to identify noninvasive methods to evaluate the severity of iron overload in transfusion-dependent ß-thalassemia and the efficiency of intensive intravenous therapy as an additional tool for the treatment of iron-overloaded patients. Iron overload was evaluated for 26 ß-thalassemia homozygous patients, and 14 of them were submitted to intensive chelation therapy with high doses of intravenous deferoxamine (DF. Patients were classified into six groups of increasing clinical severity and were divided into compliant and non-compliant patients depending on their adherence to chronic chelation treatment. Several methods were used as indicators of iron overload. Total gain of transfusion iron, plasma ferritin, and urinary iron excretion in response to 20 to 60 mg/day subcutaneous DF for 8 to 12 h daily are useful to identify iron overload; however, urinary iron excretion in response to 9 g intravenous DF over 24 h and the increase of urinary iron excretion induced by high doses of the chelator are more reliable to identify different degrees of iron overload because of their correlation with the clinical grades of secondary hemochromatosis and the significant differences observed between the groups of compliant and non-compliant patients. Finally, the use of 3-9 g intravenous DF for 6-12 days led to a urinary iron excretion corresponding to 4.1 to 22.4% of the annual transfusion iron gain. Therefore, continuous intravenous DF at high doses may be an additional treatment for these patients, as a complement to the regular subcutaneous infusion at home, but requires individual planning and close monitoring of adverse reactions.

    Full Text Available Intravenous iron preparations are typically classified as non-dextran-based or dextran/dextran-based complexes. The carbohydrate shell for each of these preparations is unique and is key in determining the various physicochemical properties, the metabolic pathway, and the immunogenicity of the iron-carbohydrate complex. As intravenous dextran can cause severe, antibody-mediated dextran-induced anaphylactic reactions (DIAR, the purpose of this study was to explore the potential of various intravenous iron preparations, non-dextran-based or dextran/dextran-based, to induce these reactions. An IgG-isotype mouse monoclonal anti-dextran antibody (5E7H3 and an enzyme-linked immunosorbent assay (ELISA were developed to investigate the dextran antigenicity of low molecular weight iron dextran, ferumoxytol, iron isomaltoside 1000, ferric gluconate, iron sucrose and ferric carboxymaltose, as well as isomaltoside 1000, the isolated carbohydrate component of iron isomaltoside 1000. Low molecular weight iron dextran, as well as dextran-based ferumoxytol and iron isomaltoside 1000, reacted with 5E7H3, whereas ferric carboxymaltose, iron sucrose, sodium ferric gluconate, and isolated isomaltoside 1000 did not. Consistent results were obtained with reverse single radial immunodiffusion assay. The results strongly support the hypothesis that, while the carbohydrate alone (isomaltoside 1000 does not form immune complexes with anti-dextran antibodies, iron isomaltoside 1000 complex reacts with anti-dextran antibodies by forming multivalent immune complexes. Moreover, non-dextran based preparations, such as iron sucrose and ferric carboxymaltose, do not react with anti-dextran antibodies. This assay allows to assess the theoretical possibility of a substance to induce antibody-mediated DIARs. Nevertheless, as this is only one possible mechanism that may cause a hypersensitivity reaction, a broader set of assays will be required to get an understanding of the

Puerperal anemia can impair postpartum maternal and neonatal well-being. Objective: To determine the effect of treatment of moderate puerperal iron-deficiency anemia using a single intravenous total-dose iron dextran versus daily single dose oral iron(III-hydroxide polymaltose. Methodology: A randomized controlled study in which postpartum women with moderate iron-deficiency anemia were randomized into treatment with either a single total-dose intravenous iron dextran or with daily single doses of oral iron(III-hydroxide polymaltose tablets for 6 weeks. Effects on hemoglobin concentration using either method were compared at 6 weeks postpartum. Analysis was per protocol using SPSS version 17 for windows. P-values ≤0.05 were considered significant. Results: Two hundred eighty-four women were recruited for the study: 142 women received single total dose intravenous infusion of iron dextran while 142 received daily oral iron(III-hydroxide polymaltose tablets. Approximately 84.0% (237/282 completed the study and were analyzed including 81% (115/142 of those randomized to injectable iron therapy compared to 85.9% (122/142 of those randomized to oral treatment.

    James R Connor

    Full Text Available There is a significant clinical need for effective treatment of iron deficiency. A number of compounds that can be administered intravenously have been developed. This study examines how the compounds are handled by macrophages and their relative potential to provoke oxidative stress.Human kidney (HK-2 cells, rat peritoneal macrophages and renal cortical homogenates were exposed to pharmaceutical iron preparations. Analyses were performed for indices of oxidative stress and cell integrity. In addition, in macrophages, iron uptake and release and cytokine secretion was monitored.HK-2 cell viability was decreased by iron isomaltoside and ferumoxytol and all compounds induced lipid peroxidation. In the renal cortical homogenates, lipid peroxidation occurred at lowest concentrations with ferric carboxymaltose, iron dextran, iron sucrose and sodium ferric gluconate. In the macrophages, iron sucrose caused loss of cell viability. Iron uptake was highest for ferumoxytol and iron isomaltoside and lowest for iron sucrose and sodium ferric gluconate. Iron was released as secretion of ferritin or as ferrous iron via ferroportin. The latter was blocked by hepcidin. Exposure to ferric carboxymaltose and iron dextran resulted in release of tumor necrosis factor α.Exposure to iron compounds increased cell stress but was tissue and dose dependent. There was a clear difference in the handling of iron from the different compounds by macrophages that suggests in vivo responses may differ.

    The aim of this study was to analyse the effect of iron supplementation in children with breath holding spells, irrespective of their iron status and study the factors associated with the response. This was a prospective interventional study. Study population comprised of patients aged 6-36 months, attending a paediatric outpatient department with recurrent episodes (more than three in last 4 weeks) of breath holding spells. Children with loss of consciousness or convulsive movements associated with breath holding spells were considered as severe. After baseline investigations, all enrolled patients were given elemental iron at the dose of 3 mg/kg/day as a single daily dose. Four weekly follow-ups were done until 3 months after initiation of the intervention. At 12 weeks, investigations were repeated and outcome assessed for remission or decrease in severity of breath holding episodes. A total of 100 children with breath holding spells received iron supplementation. Almost 73% of children showed complete response, with another 23% showing greater than 50% reduction in frequency. Frequency of spells at diagnosis and intolerance to oral iron were significantly associated with poor response to iron supplementation. Other factors such as age at onset, age at presentation, severity of spells, anaemia and serum iron parameters had no significant association with the response. Of the 27 children without iron deficiency (serum ferritin ≥ 30 µg/L), 77.7% responded completely to iron supplementation, similar to the iron-deficient group. Iron supplementation is effective in the management of breath holding spells. Non-anaemic and iron-replete children with breath holding spells also respond well to iron supplementation. © 2017 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

  12. High dose intravenous iron, mineral homeostasis and intact FGF23 in normal and uremic rats

    Science.gov (United States)

    2013-01-01

    Background High iron load might have a number of toxic effects in the organism. Recently intravenous (iv) iron has been proposed to induce elevation of fibroblast growth factor 23 (FGF23), hypophosphatemia and osteomalacia in iron deficient subjects. High levels of FGF23 are associated with increased mortality in the chronic kidney disease (CKD) population. CKD patients are often treated with iv iron therapy in order to maintain iron stores and erythropoietin responsiveness, also in the case of not being iron depleted. Therefore, the effect of a single high iv dose of two different iron preparations, iron isomaltoside 1000 (IIM) and ferric carboxymaltose (FCM), on plasma levels of FGF23 and phosphate was examined in normal and uremic iron repleted rats. Methods Iron was administered iv as a single high dose of 80 mg/kg bodyweight and the effects on plasma levels of iFGF23, phosphate, Ca2+, PTH, transferrin, ferritin and iron were examined in short and long term experiments (n = 99). Blood samples were obtained at time 0, 30, 60, 180 minutes, 24 and 48 hours and in a separate study after 1 week. Uremia was induced by 5/6-nephrectomy. Results Nephrectomized rats had significant uremia, hyperparathyroidism and elevated FGF23. Iron administration resulted in significant increases in plasma ferritin levels. No significant differences were seen in plasma levels of iFGF23, phosphate and PTH between the experimental groups at any time point within 48 hours or at 1 week after infusion of the iron compounds compared to vehicle. Conclusions In non-iron depleted normal and uremic rats a single high dose of either of two intravenous iron preparations, iron isomaltoside 1000, and ferric carboxymaltose, had no effect on plasma levels of iFGF23 and phosphate for up to seven days.

  16. Iron supplementation decreases severity of allergic inflammation in murine lung.

    Directory of Open Access Journals (Sweden)

    Laura P Hale

    Full Text Available The incidence and severity of allergic asthma have increased over the last century, particularly in the United States and other developed countries. This time frame was characterized by marked environmental changes, including enhanced hygiene, decreased pathogen exposure, increased exposure to inhaled pollutants, and changes in diet. Although iron is well-known to participate in critical biologic processes such as oxygen transport, energy generation, and host defense, iron deficiency remains common in the United States and world-wide. The purpose of these studies was to determine how dietary iron supplementation affected the severity of allergic inflammation in the lungs, using a classic model of IgE-mediated allergy in mice. Results showed that mice fed an iron-supplemented diet had markedly decreased allergen-induced airway hyperreactivity, eosinophil infiltration, and production of pro-inflammatory cytokines, compared with control mice on an unsupplemented diet that generated mild iron deficiency but not anemia. In vitro, iron supplementation decreased mast cell granule content, IgE-triggered degranulation, and production of pro-inflammatory cytokines post-degranulation. Taken together, these studies show that iron supplementation can decrease the severity of allergic inflammation in the lung, potentially via multiple mechanisms that affect mast cell activity. Further studies are indicated to determine the potential of iron supplementation to modulate the clinical severity of allergic diseases in humans.

    To determine whether administration of intravenous iron in a patient diagnosed with hip fracture reduces the need for blood transfusion. A retrospective observational case-control study was performed comparing a control group of 63 patients diagnosed with hip fracture with another group of 57 patients treated with parenteral iron. Demographic, clinical condition/clinical record and hematometric differences of the case-control patients were described. We analyzed the morbidity (post-surgical infection) and mortality rate. SPSS(®) was used for statistical studies. Being statistically significant, after the administration of intravenous iron sucrose, the need of blood transfusion was reduced in the case group, as well as the quantity of concentrates required (1.37 vs 0.6). In the case group, there was a statistically significant decreasing trend in hospital mortality rate (case group: 0.8%/control group: 8.3%). It was not been proven the relation between the decrease in nosocomial infection and the administration of intravenous iron The administration of intravenous iron sucrose in patients diagnosed with hip fracture before surgery could be effective blood saving measure in this type of trauma surgery. Furthermore, its use has been reliable without causing any side effects. Copyright © 2012 Elsevier España, S.L. All rights reserved.

  18. Iron Supplementation and Altitude: Decision Making Using a Regression Tree

    Full Text Available Altitude exposure increases the body’s need for iron (Gassmann and Muckenthaler, 2015, primarily to support accelerated erythropoiesis, yet clear supplementation guidelines do not exist. Athletes are typically recommended to ingest a daily oral iron supplement to facilitate altitude adaptations, and to help maintain iron balance. However, there is some debate as to whether athletes with otherwise healthy iron stores should be supplemented, due in part to concerns of iron overload. Excess iron in vital organs is associated with an increased risk of a number of conditions including cancer, liver disease and heart failure. Therefore clear guidelines are warranted and athletes should be discouraged from ‘self-prescribing” supplementation without medical advice. In the absence of prospective-controlled studies, decision tree analysis can be used to describe a data set, with the resultant regression tree serving as guide for clinical decision making. Here, we present a regression tree in the context of iron supplementation during altitude exposure, to examine the association between pre-altitude ferritin (Ferritin-Pre and the haemoglobin mass (Hbmass response, based on daily iron supplement dose. De-identified ferritin and Hbmass data from 178 athletes engaged in altitude training were extracted from the Australian Institute of Sport (AIS database. Altitude exposure was predominantly achieved via normobaric Live high: Train low (n = 147 at a simulated altitude of 3000 m for 2 to 4 weeks. The remaining athletes engaged in natural altitude training at venues ranging from 1350 to 2800 m for 3-4 weeks. Thus, the “hypoxic dose” ranged from ~890 km.h to ~1400 km.h. Ethical approval was granted by the AIS Human Ethics Committee, and athletes provided written informed consent. An in depth description and traditional analysis of the complete data set is presented elsewhere (Govus et al., 2015. Iron supplementation was prescribed by a sports physician

    A 67-year-old woman known to have iron deficiency anemia and persistent unexplained chronic leukopenia was cared for by our medical center for about 16 years. During this period she was examined thoroughly and diagnosed to have chronic idiopathic neutropenia (also known as chronic benign neutropenia). Her iron deficiency was attributed to nutritional factors and she was non-compliant with her oral iron supplements. The patient fully received her iron supplement medication by nursing staff for two and a half months during an unexpected prolonged hospital stay after her suffering an acute ischemic cerebrovascular accident. An astonishing outcome was that in addition to having her iron deficiency anemia treated, her long-term unexplained neutropenia was also corrected. Some patients diagnosed with chronic idiopathic neutropenia and clinically present as having unexplained chronic neutropenia might actually be suffering from a form of not yet described iron deficiency induced neutropenia.

    Iron oxide nanoparticles (IONP) are being developed for use as a cancer treatment. They have demonstrated efficacy when used either as a monotherapy or in conjunction with conventional chemotherapy and radiation. The success of IONP as a therapeutic tool depends on the delivery of a safe and controlled cytotoxic thermal dose to tumor tissue following activation with an alternating magnetic field (AMF). Prior to clinical approval, knowledge of IONP toxicity, biodistribution and physiological clearance is essential. This preliminary time-course study determines the acute toxicity and biodistribution of 110 nm dextran-coated IONP (iron) in mice, 7 days post systemic, at doses of 0.4, 0.6, and 1.0 mg Fe/ g mouse bodyweight. Acute toxicity, manifested as changes in the behavior of mice, was only observed temporarily at 1.0 mg Fe/ g mouse bodyweight, the highest dose administered. Regardless of dose, mass spectrometry and histological analysis demonstrated over 3 mg Fe/g tissue in organs within the reticuloendotheilial system (i.e. liver, spleen, and lymph nodes). Other organs (brain, heart, lungs, and kidney) had less than 0.5 mg Fe/g tissue with iron predominantly confined to the organ vasculature.

    Iron depletion is common in regular blood donors. The objective of the study was to investigate the frequency and severity of iron depletion in regular blood donors and whether IV iron is more effective than oral to avoid iron depletion and symptoms thereof, especially restless legs syndrome (RLS). One hundred and twenty blood donors with at least five previous whole blood donations were randomized to receive either IV iron sucrose (Venofer(®), RenaPharma/Vifor, Uppsala, Sweden), 200 mg, or to 20×100 mg of oral iron sulphate (Duroferon(®), GlaxoSmithKline, Stockholm, Sweden), after each blood donation during 1 year. Iron status and RLS incidence and severity were investigated. Iron status was generally poor among regular blood donors, especially in women, with a high incidence of iron depletion (>20%) and RLS (18%). The IV iron group increased storage iron to a greater extent than the oral iron group after 12 months (P=0·0043). Female donors were more responsive to IV iron sucrose compared to oral iron sulphate, particularly female donors below 50 years of age. RLS severity scores were significantly lower in the IV iron group. The two treatments were safe. Iron status is poor in regular blood donors, restless legs syndrome is common, and the routine iron supplementation is insufficient. IV iron sucrose substitutes iron loss in blood donors more efficiently compared with oral iron sulphate, especially in women. Iron substitution to blood donors should be individualized and based on P-ferritin monitoring. © 2010 The Author(s). Vox Sanguinis © 2010 International Society of Blood Transfusion.

    Background Iron-deficiency anaemia is common during childhood. Iron administration has been claimed to increase the risk of malaria. Objectives To evaluate the effects and safety of iron supplementation, with or without folic acid, in children living in areas with hyperendemic or holoendemic malaria transmission. Search methods We searched the Cochrane Infectious Diseases Group Specialized Register; the Cochrane Central Register of Controlled Trials (CENTRAL), published in the Cochrane Library, MEDLINE (up to August 2015) and LILACS (up to February 2015). We also checked the metaRegister of Controlled Trials (mRCT) and World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) up to February 2015. We contacted the primary investigators of all included trials, ongoing trials, and those awaiting assessment to ask for unpublished data and further trials. We scanned references of included trials, pertinent reviews, and previous meta-analyses for additional references. Selection criteria We included individually randomized controlled trials (RCTs) and cluster RCTs conducted in hyperendemic and holoendemic malaria regions or that reported on any malaria-related outcomes that included children younger than 18 years of age. We included trials that compared orally administered iron, iron with folic acid, and iron with antimalarial treatment versus placebo or no treatment. We included trials of iron supplementation or fortification interventions if they provided at least 80% of the Recommended Dietary Allowance (RDA) for prevention of anaemia by age. Antihelminthics could be administered to either group, and micronutrients had to be administered equally to both groups. Data collection and analysis The primary outcomes were clinical malaria, severe malaria, and death from any cause. We assessed the risk of bias in included trials with domain-based evaluation and assessed the quality of the evidence using the Grading of Recommendations Assessment

    Breath-holding attacks are common during childhood. Iron supplementation has been claimed to reduce the frequency or severity, or both, of breath-holding attacks in children. To assess the effect of iron supplementation on the frequency and severity of breath-holding attacks in children. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE, EMBASE, PsycINFO, CINAHL and the metaRegister of Controlled Trials (up to April 2009). We scanned references of included trials. Pharmaceutical companies manufacturing oral iron supplements and some trial authors were contacted for any unpublished data or trials. Randomised and quasi-randomised controlled trials comparing iron supplementation with placebo or no therapy in children breath-holding episodes. These were reported by an observer. The primary outcome was reduction in the frequency (number over time) or severity (leading to cessation of loss of consciousness or convulsive movements), or both, of breath-holding attacks. Two authors (AZ and NO) independently selected studies and extracted data. Study authors were contacted for missing data, where necessary. Risk of bias was assessed using domain-based evaluation. In the presence of low heterogeneity, a fixed-effect meta-analysis was performed with pooled results presented as odds ratios (OR) and 95% confidence intervals (CIs). Two trials (87 children) fulfilled the inclusion criteria. In these trials, iron supplementation significantly reduced the frequency of breath-holding attacks in children (OR 76.48; 95% CI 15.65 to 373.72; P breath-holding attacks maintained this significance (OR 53.43; 95% CI 6.57 to 434.57; P = 0.0002). Iron supplementation (at 5 mg/kg/day of elemental iron for 16 weeks) appears to be useful in reducing the frequency and severity of breath-holding attacks. Supplementation is of particular benefit in children with iron deficiency anaemia, responses correlating with the improvements in haemoglobin

    The aim of the study was to establish an optimized protocol of iron dextran administration to pig neonates, which better meets the iron demand for erythropoiesis. Here, we monitored development of red blood cell indices, plasma iron parameters during a 28-day period after birth (till the weaning), following intramuscular administration of different concentrations of iron dextran to suckling piglets. To better assess the iron status we developed a novel mass spectrometry assay to quantify pig plasma levels of the iron-regulatory peptide hormone hepcidin-25. This hormone is predominantly secreted by the liver and acts as a negative regulator of iron absorption and reutilization. The routinely used protocol with high amount of iron resulted in the recovery of piglets from iron deficiency but also in strongly elevated plasma hepcidin-25 levels. A similar protocol with reduced amounts of iron improved hematological status of piglets to the same level while plasma hepcidin-25 levels remained low. These data show that plasma hepcidin-25 levels can guide optimal dosing of iron treatment and pave the way for mixed supplementation of piglets starting with intramuscular injection of iron dextran followed by dietary supplementation, which could be efficient under condition of very low plasma hepcidin-25 level.

    Understanding physicochemical properties of intravenous (IV) iron drug products is essential to ensure the manufacturing process is consistent and streamlined. The history of physicochemical characterization of IV iron complex formulations stretches over several decades, with disparities in iron core size and particle morphology as the major source of debate. One of the main reasons for this controversy is room temperature sample preparation artifacts, which affect accurate determination of size, shape and agglomeration/aggregation of nanoscale iron particles. The present study is first to report the ultra-fine iron core structures of four IV iron complex formulations, sodium ferric gluconate, iron sucrose, low molecular weight iron dextran and ferumoxytol, using a cryogenic transmission electron microscopy (cryo-TEM) preservation technique, as opposed to the conventional room temperature (RT-TEM) technique. Our results show that room temperature preparation causes nanoparticle aggregation and deformation, while cryo-TEM preserves IV iron colloidal suspension in their native frozen-hydrated and undiluted state. In contrast to the current consensus in literature, all four IV iron colloids exhibit a similar morphology of their iron oxide cores with a spherical shape, narrow size distribution and an average size of 2nm. Moreover, out of the four tested formulations, ferumoxytol exhibits a cluster-like community of several iron carbohydrate particles which likely accounts for its large hydrodynamic size of 25nm, measured with dynamic light scattering. Our findings outline a suitable method for identifying colloidal nanoparticle core size in the native state, which is increasingly important for manufacturing and design control of complex drug formulations, such as IV iron drug products.

    To analyze the effects to iron status who were given preventive iron supplements for two months from when they were breast-fed to four-month-old. A total of 123 infants in four-month-old age who were breast-fed were randomly divided into iron supplementation group (63 cases) and control group (60 cases), iron supplementation group was supplied with low-dose iron (1 mg×kg⁻¹×d⁻¹) for two months with no intervention for control group. Blood samples were collected to test C reactive protein and iron status indicators in six-month-old age group infants, and the growth indices were measured and compared on the gender difference of iron status at and 6 months. After 2 months of low-dose iron supplementation, the hemoglobin of iron supplementation group (26 cases) increased about 5.5 g/L while the control group (34 cases) increases about 0.0 g/L (median), 95% confidence intervals were -7.0 - 13.0 g/L and -9.0 - 15.0 g/L, respectively. The hemoglobin increase of iron supplementation group was higher than the control group, the difference was statistically significant (u = -2.326, P nutritional status and the growth did not show any significant difference between iron supplementation group and control group (P > 0.05). At age 6 month, the MCV of the boys were (75.89 ± 3.34) fl, while the girls were (77.20 ± 3.17) fl. The boys had lower values of MCV than the girls, and the gender difference was statistically significant (t = 4.73, P nutritional status did not show any significant gender difference (P > 0.05). Low-dose iron supplementation of breast-fed infants at 4-month-old can increase the hemoglobin level when they were 6-month-old, and had no measurable side effect on growth.

    Full Text Available Background & objectives: Iron deficiency anaemia (IDA is the most common nutritional deficiency in pregnancy. Prophylactic oral iron is recommended during pregnancy to meet the increased requirement. In India, women become pregnant with low baseline haemoglobin level resulting in high incidence of moderate to severe anaemia in pregnancy where oral iron therapy cannot meet the requirement. Pregnant women with moderate anaemia are to be treated with parentral iron therapy. This study was undertaken to evaluate the response and effect of intravenous iron sucrose complex (ISC given to pregnant women with IDA. Methods: A prospective study was conducted (June 2009 to June 2011 in the department of Obstetrics & Gynecology, All India Institute of Medical Sciences, New Delhi. One hundred pregnant women with haemoglobin between 5-9 g% with diagnosed iron deficiency attending antenatal clinic were given intravenous iron sucrose complex in a dose of 200 mg twice weekly schedule after calculating the dose requirement. Results: The mean haemoglobin raised from 7.63 ± 0.61 to 11.20 ± 0.73 g% (P<0.001 after eight wk of therapy. There was significant rise in serum ferritin levels (from 11.2 ± 4.7 to 69 ± 23.1 μg/l (P<0.001. Reticulocyte count increased significantly after two wk of starting therapy (from 1.5 ± 0.6 to 4.6±0.8%.Other parameters including serum iron levels and red cell indices were also improved significantly. Only one woman was lost to follow up. No major side effects or anaphylactic reactions were noted during study period. Interpretation & conclusions: Parentral iron therapy was effective in increasing haemoglobin, serum ferritin and other haematological parameters in pregnant women with moderate anaemia. Intravenous iron sucrose can be used in hospital settings and tertiary urban hospitals where it can replace intramuscular therapy due to injection related side effects. Further, long-term comparative studies are required to recommend its

    The effects of growth, menstrual status, and calcium supplementation on iron status were studied over 4 y in 354 girls in pubertal stage 2 who were premenarcheal at baseline (x+/-SD age: 10.8+/-0.8 y). Girls were randomly assigned to placebo or treatment with 1000 mg Ca/d as calcium citrate malate. Anthropometric characteristics, bone mass, and nutritional status were measured biannually; ferritin was measured annually; and red blood cell indexes were determined at 4 y. The simultaneous effects of iron intake and menstrual status on serum ferritin, after change in lean body mass (LBM) was controlled for, were evaluated in subjects in the upper and lower quartiles of cumulative iron intake. The average maximal accumulation of LBM (386 g/mo; 95% CI: 372, 399) occurred 0.5 y before the onset of menarche. Change in LBM was a significant predictor of serum ferritin (P < 0.0001), with a negative influence on iron status (t ratio=-4.12). The 2 fitted mathematical models representing ferritin concentrations of subjects in the upper and lower quartiles of cumulative iron intake were significantly different (P < 0.018). The regression line of the ferritin concentration in menstruating girls with high iron intakes had a less negative slope than the line fit to serum ferritin concentrations in girls with low iron intakes (NS). Serum ferritin concentrations at 0, 1, 2, 3, and 4 y were not significantly different between groups. In addition, there was no significant difference between groups in any of the red blood cell indexes. In summary, growth spurt and menstrual status had adverse effects on iron stores in adolescent girls with low iron intakes (<9 mg/d), whereas long-term supplementation with calcium (total intake: approximately 1500 mg/d) did not affect iron status.

    Aims The appropriate use of intravenous (IV) iron is essential to minimise the requirements for erythropoiesis-stimulating agents (ESAs). The clinical efficacy of generic IV iron compared to the original formulation is controversial. We evaluated the changes that were induced after switching from a generic IV iron to an original formulation in a stable, prevalent haemodialysis (HD) population. Methods A total of 342 patients were included, and the follow-up period was 56 weeks for each formulation. Anaemia parameters and doses of ESA and IV iron were prospectively recorded before and after the switch from generic to original IV iron. Results To maintain the same haemoglobin (Hb) levels after switching from the generic to the original formulation, the requirements for IV iron doses were reduced by 34.3% (from 52.8±33.9 to 34.7±31.8mg/week, p<0.001), and the ESA doses were also decreased by 12.5% (from 30.6±23.6 to 27±21μg/week, p<0.001). The erythropoietin resistance index declined from 8.4±7.7 to 7.4±6.7 IU/kg/week/g/dl after the switch from the generic to the original drug (p = 0.001). After the switch, the transferrin saturation ratio (TSAT) and serum ferritin levels rose by 6.8%(p<0.001) and 12.4%(p = 0.001), respectively. The mortality rate was similar for both periods. Conclusions The iron and ESA requirements are lower with the original IV iron compared to the generic drug. In addition, the uses of the original formulation results in higher ferritin and TSAT levels despite the lower dose of IV iron. Further studies are necessary to analyse the adverse effects of higher IV iron dosages. PMID:26322790

    Several treatment modalities exist for the treatment of perioperative anemia. We determined the effect of oral iron supplementation on preoperative anemia, and the use of blood-conserving interventions before total hip arthroplasty (THA) and total knee arthroplasty (TKA). A total of 3435 total joint arthroplasties (1461 THAs and 1974 TKAs) were analyzed during 2 phases of a blood conservation program. The first phase used erythropoietin alfa (EPO) or intravenous (IV) iron for patients at risk for perioperative anemia. The second phase included these interventions, as well as preoperative iron supplementation. The effect on preoperative hemoglobin (Hb) and serum ferritin, as well as EPO and IV iron utilization, was determined. Oral iron therapy increased preoperative Hb level by 6 g/L (P iron reduced from 4% to 2% (P = .05) and 5% to 2% (P iron therapy reduced the burden of perioperative anemia and reduced utilization of other blood-conserving therapies before THA and TKA. Future research should delineate the cost-effectiveness of oral iron therapy. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available BACKGROUND Anaemia in pregnancy continues to be a major public health problem with 54.96% of the pregnant population suffering from it in our setup. Despite the National Anaemia Prophylaxis Programme, anaemia complicating pregnancy continues to be a widespread problem with adverse effects on maternal and foetal outcome. The aim of the study is to find out an alternate iron therapy in the form of intravenous iron-sucrose and to determine its therapeutic effectiveness, safety and compliance in the management of anaemic expectant mother and to compare it with that of conventional oral iron therapy. MATERIALS AND METHODS The study was a randomised controlled clinical trial carried out in the Department of Obstetrics and Gynaecology in collaboration with the Department of Biochemistry, Regional Institute of Medical Sciences (RIMS, Imphal. 100 pregnant women in second or third trimester with mild or moderate anaemia were selected, 50 as study group (intravenous iron and 50 as controls (oral iron. Initial evaluation included complete blood count and serum ferritin level and reevaluated on the 14th and 28th day of initiation of therapy. RESULTS Majority of patients (42% in the study as well as control group were between 26-30 years of age. The mean ± SD increase in haemoglobin and ferritin levels on 28th day were 2.66 ± 0.34 gm/dL and 27.65 ± 1.80 ng/mL in study group and 1.55 ± 0.23 gm/dL and 16.89 ± 0.76 ng/mL in control group respectively, both of which were statistically significant. CONCLUSION The mean haemoglobin and serum ferritin levels throughout the treatment were significantly higher in the intravenous ironsucrose group than in the orally administered iron group and significantly higher number of patients achieved the target haemoglobin of 11.0 gm/dL after 28 days of treatment. This reduces the blood transfusion rates in pregnant women with severe anaemia near term.

    Full Text Available Vitamin A (VA and iron deficiencies are important nutritional problems, affecting particularly preschool children, as well as pregnant and lactating women. A PubMed (National Library of Medicine, National Institutes of Health, Bethesda, MD, USA literature review was carried out to search for clinical trials published from 1992 to 2013 that assessed the influence of vitamin A supplementation on iron status. Simultaneous use of iron and vitamin A supplements seemed to be more effective to prevent iron deficiency anemia than the use of these micronutrients alone. Some studies did not include a placebo group and only a few of them assessed vitamin A status of the individuals at baseline. Moreover, the studies did not consider any inflammatory marker and a reasonable number of iron parameters. Another important limitation was the lack of assessment of hemoglobin variants, especially in regions with a high prevalence of anemia. Assessment of hemoglobin variants, inflammatory markers and anemia of chronic inflammation would be important to the studies investigated. Studies involving different populations are necessary to elucidate the interaction between the two micronutrients, especially regarding iron absorption and modulation of erythropoiesis.

Intravenous iron has shown clinical benefit compared to oral iron therapy. Aim: This study aimed to compare health care outcomes and costs after oral vs intravenous iron treatment for IBD patients with iron deficiency or iron deficiency anemia (ID/A in Germany. Methods: IBD patients with ID/A were identified by ICD-10-GM codes and newly commenced iron treatment via ATC codes in 2013 within the InGef (formerly Health Risk Institute research claims database. Propensity score matching was performed to balance both treatment groups. Non-observable covariates were adjusted by applying the difference-in-differences (DID approach. Results: In 2013, 589 IBD patients with ID/A began oral and 442 intravenous iron treatment. After matching, 380 patients in each treatment group were analyzed. The intravenous group had fewer all-cause hospitalizations (37% vs 48% and ID/A-related hospitalizations (5% vs 14% than the oral iron group. The 1-year preobservation period comparison revealed significant health care cost differences between both groups.

We conducted a retrospective chart review, including all patients with CKD and IDA who were treated with iron dextran total dose infusion (TDI between 2002 and 2007. Patient demographics were noted, and laboratory values for creatinine, hemoglobin (Hgb, iron stores and PLT were recorded pre- and post-dose. Results. 153 patients received a total of 251 doses of TDI (mean ± SD = 971 ± 175 mg; age years and Creatinine  mg/dL. All CKD stages were represented (stage 4 commonest. Hgb and Fe stores improved post-TDI (. There was a very mild decrease in PLT (pre-TDI 255 versus post-TDI 244, .

    Both iron deficiency (ID) and excess can lead to impaired health status. There is substantial evidence of a U-shaped curve between the risk of adverse birth outcomes and maternal hemoglobin concentrations during pregnancy; however, it is unclear whether those relations are attributable to conditions of low and high iron status or to other mechanisms. We summarized current evidence from human studies regarding the association between birth outcomes and maternal hemoglobin concentrations or iron status. We also reviewed effects of iron supplementation on birth outcomes among women at low risk of ID and the potential mechanisms for adverse effects of high iron status during pregnancy. Overall, we confirmed a U-shaped curve for the risk of adverse birth outcomes with maternal hemoglobin concentrations, but the relations differ by trimester. For low hemoglobin concentrations, the link with adverse outcomes is more evident when hemoglobin concentrations are measured in early pregnancy. These relations generally became weaker or nonexistent when hemoglobin concentrations are measured in the second or third trimesters. Associations between high hemoglobin concentration and adverse birth outcomes are evident in all 3 trimesters but evidence is mixed. There is less evidence for the associations between maternal iron status and adverse birth outcomes. Most studies used serum ferritin (SF) concentrations as the indicator of iron status, which makes the interpretation of results challenging because SF concentrations increase in response to inflammation or infection. The effect of iron supplementation during pregnancy may depend on initial iron status. There are several mechanisms through which high iron status during pregnancy may have adverse effects on birth outcomes, including oxidative stress, increased blood viscosity, and impaired systemic response to inflammation and infection. Research is needed to understand the biological processes that underlie the U-shaped curves

    To compare the efficacy of intravenous iron and oral iron for prevention of blood transfusions in gynecologic cancer patients receiving platinum-based chemotherapy. Sixty-four non anemic gynecologic cancer patients receiving adjuvant platinum-based chemotherapy were stratified and randomized according to baseline hemoglobin levels and chemotherapy regimen. The study group received 200mg of intravenous iron sucrose immediately after each chemotherapy infusion. The control group received oral ferrous fumarate at a dose of 200mg three times a day. Complete blood count was monitored before each chemotherapy infusion. Blood transfusions were given if hemoglobin level was below 10mg/dl. There were 32 patients in each group. No significant differences in baseline hemoglobin levels and baseline characteristics were demonstrated between both groups. Nine patients (28.1%) in the study group and 18 patients (56.3%) in the control group required blood transfusion through 6 cycles of chemotherapy (p=0.02). Fewer median number of total packed red cell units were required in the study group compared to the control group (0 and 0.5 unit, respectively, p=0.04). Serious adverse events and hypersensitivity reactions were not reported. However, constipation was significantly higher in the control group (3.1% and 40.6%, p=gynecologic cancer patients receiving platinum-based chemotherapy, associated with less constipation than the oral formulation. © 2013 Elsevier Inc.

    Anemia is a common extraintestinal manifestation in patients with inflammatory bowel disease, impacting disease prognosis, morbidity, hospitalization rates and time lost from work. While iron deficiency anemia and anemia of chronic inflammation predominate, combinations of hematimetric and biochemical markers facilitate the diagnosis and targeted therapy of other etiologies according to their underlying pathophysiological causes. Intravenous iron replacement is currently recommended in IBD patients with moderate to severe anemia or intolerance to oral iron. Areas covered: This review examines the impact, pathophysiology and diagnostics of iron deficiency and anemia, compares the characteristics and safety profiles of available oral and intravenous iron preparations, and highlights issues which require consideration in decision making for therapy administration and monitoring. Expert opinion: Modern intravenous iron formulations have been shown to be safe and effective in IBD patients, allowing rapid anemia correction and repletion of iron stores. While traditional oral iron preparations are associated with increased inflammation, negative effects on the microbiome, and poor tolerance and compliance, first clinical trial data indicate that newer oral compounds such as ferric maltol and sucrosomial iron offer improved tolerability and may thus offer a viable alternative for the future.

    Intake of supplements containing iron or a combination of iron and folic acid by pregnant women may improve maternal health and pregnancy outcomes. Recently, intermittent supplementation regimens have been proposed as alternatives to daily regimens. To assess the effectiveness and safety of daily and intermittent use of iron or iron+folic acid supplements by pregnant women. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (March 2009) and contacted relevant organisations for the identification of ongoing and unpublished studies. All randomised or quasi-randomised trials evaluating the effect of supplementation with iron or iron+folic acid during pregnancy. We assessed the methodological quality of trials using the standard Cochrane criteria. Two authors independently assessed which trials to include in the review and one author extracted data. We included 49 trials, involving 23,200 pregnant women. Overall, the results showed significant heterogeneity across most prespecified outcomes and were analysed assuming random-effects. The trials provided limited information related to clinical maternal and infant outcomes.Overall, daily iron supplementation was associated with increased haemoglobin levels in maternal blood both before and after birth and reduced risk of anaemia at term. These effects did not differ significantly between women receiving intermittent or daily iron or iron+folic acid supplementation. Women who received daily prenatal iron supplementation with or without folic acid were less likely to have iron deficiency at term as defined by current cut-off values than those who received no treatment or placebo. Side effects and haemoconcentration (a haemoglobin level greater than 130 g/L) were more common among women who received daily iron or iron+folic acid supplementation than among those who received no treatment or placebo. The risk of haemoconcentration during the second and third trimester was higher among those on a daily

    Insufficient iron levels for optimal fetal and infant development is a concern during pregnancy and infancy. The goal of this study was to assess the effects of iron supplementation in pregnancy and/or infancy on motor development at 9 months. The study was a randomized controlled trial (RCT) of infancy iron supplementation linked to an RCT of pregnancy iron supplementation, conducted in Hebei, China. A total of 1482 infants were randomly assigned to receive placebo (n = 730) or supplemental iron (n = 752) from 6 weeks to 9 months. Gross motor development (assessed by using the Peabody Developmental Motor Scale, Second Edition, instrument) was the primary outcome. Neurologic integrity and motor quality were secondary outcomes. Motor outcome was available for 1196 infants, divided into 4 supplementation period groups: (1) placebo in pregnancy/placebo in infancy (n = 288); (2) placebo in pregnancy/iron in infancy (n = 305); (3) iron in pregnancy/placebo in infancy (n = 298); and (4) iron in pregnancy/iron in infancy (n = 305). Using the Peabody Developmental Motor Scale, instrument, iron supplementation in infancy but not pregnancy improved gross motor scores: overall, P motor scores by 0.3 SD compared with no supplementation or supplementation during pregnancy alone. Effects of iron supplementation in infancy alone were similar to effects with iron in both pregnancy and infancy. The RCT design supports the causal inference that iron supplementation in infancy, with or without iron supplementation in pregnancy, improved gross motor test scores at 9 months.

    Full Text Available OBJECTIVE: Intravenous iron is widely used to treat iron deficiency in day-care units. Ferric carboxymaltose (FCM allows administration of larger iron doses than iron sucrose (IS in each infusion (1000 mg vs. 200 mg. As FCM reduces the number of infusions required but is more expensive, we performed a cost-minimization analysis to compare the cost impact of the two drugs. MATERIALS AND METHODS: The number of infusions and the iron dose of 111 consecutive patients who received intravenous iron at a gastrointestinal diseases day-care unit from 8/2007 to 7/2008 were retrospectively obtained. Costs of intravenous iron drugs were obtained from the Spanish regulatory agencies. The accounting department of the Hospital determined hospital direct and indirect costs for outpatient iron infusion. Non-hospital direct costs were calculated on the basis of patient interviews. In the pharmacoeconomic model, base case mean costs per patient were calculated for administering 1000 mg of iron per infusion using FCM or 200 mg using IS. Sensitivity analysis and Monte Carlo simulation were performed. RESULTS: Under baseline assumptions, the estimated cost of iron infusion per patient and year was €304 for IS and €274 for FCM, a difference of €30 in favour of FCM. Adding non-hospital direct costs to the model increased the difference to €67 (€354 for IS vs. €287 for FCM. A Monte Carlo simulation taking into account non-hospital direct costs favoured the use of FCM in 97% of simulations. CONCLUSION: In this pharmacoeconomic analysis, FCM infusion reduced the costs of iron infusion at a gastrointestinal day-care unit.

    Iron in high doses or when given to non-anaemic women may have adverse effects on pregnancy outcomes. This study aimed to estimate the supplemental iron intake in non-anaemic pregnant women attending an urban antenatal care setting in South India and examine the association of supplemental iron intake with birth outcomes. A cohort of 1196 non-anaemic pregnant women was studied. Daily supplemental iron intake was calculated as total supplemental iron consumed (mg) during pregnancy divided by the total number of days the supplement was recommended. Association of tertiles of supplemental iron intake with term low birth weight (tLBW), preterm delivery and small for gestational age (SGA) was examined using log-binomial regression, adjusting for maternal age, height, body mass index at recruitment, parity, education and type of delivery. Mean haemoglobin in trimester 1 was 12.4 ± 0.9 g/dl and mean supplemental iron intake was 37.7 ± 4.0 mg/day. Women in the highest tertile (>39.2 mg/day) of supplemental iron intake had an increased risk of tLBW as compared with the lowest tertile (⩽ 36.6 mg/day) (adjusted risk ratio: 1.89; 95% confidence interval: 1.26, 2.83). Although supplemental iron intake was negatively correlated with gestational age (r=-0.20, Pbirth weight (r=-0.07, P=0.011), there was no association between preterm delivery or SGA and supplemental iron intake. It appears that iron supplementation in non-anaemic pregnant women may not be beneficial, as we have observed the adverse effects with a prescribed dose of 45 mg/day. This may warrant the consideration of an individualized approach for antenatal iron supplementation, especially in non-anaemic women.

    Iron-deficiency anemia is still prevalent among pregnant women living in industrialized countries such as Canada. To prevent this deficiency, iron supplements (30 mg/d) are routinely prescribed to Canadian pregnant women. Recently, dietary reference intakes for iron have increased from 18 and 23 mg/d during the second and third trimesters, respectively, to 27 mg/d throughout the pregnancy for all age groups. Whether this new recommendation implies an increase of iron dosage in supplements has not been answered. Are there any benefits or risks for the mother and her infant associated with iron supplementation during pregnancy? If iron supplementation is recommended, what should be the ideal dosage? This article reviews current knowledge on the potential negative or positive impact of iron supplementation during pregnancy on the outcomes of both infants and mothers. Based on the literature reviewed, a low daily dose of iron (30 mg elemental iron) during pregnancy improves women's iron status and seems to protect their infants from iron-deficiency anemia. Several studies have also shown that a low daily dose of iron may improve birth weight even in non-anemic pregnant women. However, higher dosages are not recommended because of the potential negative effects on mineral absorption, oxidative pathways, and adverse gastrointestinal symptoms. To date, it is still not clear if health professionals should recommend routine or selective supplementation. However, neither routine nor selective iron supplementation during pregnancy is able to eliminate iron-deficiency anemia. Even though the dietary reference intake for iron during pregnancy has been recently increased, we do not recommend higher doses of iron in supplements designed for pregnant women.

    Background Iron deficiency anemia is one of the major public health problems mostly affecting pregnant women of developing countries like Nepal. Kathmandu, the capital city of Nepal, has considerably high prevalence of anemia, which is attributed to inadequate dietary iron and problems of compliance to iron and folic acid supplementation. Objective This descriptive study aimed to identify the levels of and determinants associated with compliance regarding Iron and folic acid supplementation among pregnant women in Kathmandu, Nepal. Method The study was conducted in Paropakar Maternity and Women's Hospital in Kathmandu. Systematic random sampling was done to select a total of 406 samples that were either handed questionnaire for self-administration or interviewed. The χ2 test and multiple linear regressions were used for statistical analysis. Result The findings showed 73.2% of the respondents had high compliance, 12.8% moderate compliance, and 14% low compliance to iron and folic acid supplementation. More than half of the respondents had insufficient knowledge regarding anemia, iron deficiency and iron and folic acid supplementation. Multiple linear regression revealed that perceived severity, perceived barriers and social support were determinants of compliance to iron and folic acid supplementation (pknowledge and awareness regarding anemia, iron deficiency, and iron and folic acid supplementation among pregnant women, and improvement in social support and perception of severity of the disease, and minimization of associated barriers may lead to better outcome in terms of compliance to iron and folic acid supplementation among pregnant women.

    Full Text Available Objective. We aimed to demonstrate safety and efficacy of intravenous (IV low molecular weight iron dextran (LMWID during treatment of anemic stage 3 and 4 chronic kidney disease (CKD patients. Methods. Efficacy data was obtained by retrospective chart review of 150 consecutively enrolled patients. Patients were assigned per protocol to oral or IV iron, with IV iron given to those with lower iron stores and/or hemoglobin. Iron and darbepoetin were administered to achieve and maintain hemoglobin at 10–12 g/dL. Efficacy endpoints were mean hemoglobin and change in iron indices approximately 30 and 60 days after enrollment. Safety data was obtained by retrospective review of reported adverse drug events (ADEs following 1699 infusions of LMWID (0.5–1.0 g. Results. Mean hemoglobin, iron saturation, and ferritin increased significantly from baseline to 60 days in patients assigned to LMWID (hemoglobin: 11.3 versus 9.4 g/dL; iron saturation: 24% versus 12.9%; ferritin: 294.7 versus 134.7 ng/mL; all . Iron stores and hemoglobin were maintained in the group assigned to oral iron. Of 1699 iron dextran infusions, three ADEs occurred. Conclusions. Treatment of anemia in CKD stages 3 and 4 with LMWID and darbepoetin is efficacious. The serious ADE rate was 0.06% per infusion.

    To evaluate the effectiveness of intravenous iron treatment, with or without associated erythropoietin (rHuEPO), measured as haemoglobin (Hb) increase. The relationships between the Hb increase and parameters used to evaluate anaemia were analysed. Retrospective observational study carried out in two third-level hospitals between January 2005 and December 2009. The study included patients with iron deficiency anaemia scheduled for elective orthopaedic surgery and treated with intravenous iron sucrose alone or associated with rHuEPO. Treatment efficacy was analysed based on the Hb increase from baseline to just before surgery. A total of 412 patients who received a median of 800mg of iron sucrose were included; 125 of them (30.4%) additionally received 2.4 vials of rHuEPO. The Hb increase was 0.8 (1.1) g/dL in patients treated with intravenous iron and 1.5 (1.3) g/dL in those additionally given rHuEPO(P<.01). The percentage of hypochromic red blood cells (r=0.52) and soluble transferrin receptor (r=0.59) value were significantly correlated to the Hb increase in patients receiving iron. In patients with iron deficiency anaemia, the effectiveness of iron sucrose treatment to optimize Hb before surgery was moderate; adjuvant administration of erythropoietin improved the results. Determination of functional iron status parameters may improve the treatment effectiveness. Copyright © 2014 Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor.

    Iron deficiency is the commonest treatable cause of postpartum anaemia. Parenteral iron therapy results in faster and higher replenishment of iron stores and correction of haemoglobin levels with better compliance. Ferric Carboxy Maltose is an effective and a safe option which can be administered intravenously in single total correction dose without any serious adverse effects.The study was done to evaluate the efficacy and safety of Ferric Carboxy Maltose in the treatment of iron deficiency anaemia in post-natal patients. It was an open, single arm study including 615 women with diagnosis of Iron deficiency anaemia and haemoglobin (Hb) levels between 4gm% and 11gm% from January 2013 to December 2016. Intravenous Ferric Carboxy Maltose(500-1500mg) was administered and the improvement in haemoglobin levels and iron stores were assessed after three weeks of total dose infusion. Out of the 615 women, 595 women were included in the analysis. Most of the women were in the age group of 27-30 years. Most of the women had mild anaemia as per World Health Organisation guidelines. Mean hemoglobin levels significantly increased over a period of three weeks after Ferric Carboxy Maltose administration. Other parameters like total iron binding capacity, Ferritin and Iron also had a significant improvement after Ferric Carboxy Maltose administration. No serious adverse events were observed after Ferric Carboxy Maltose. Intravenous Ferric Carboxy Maltose was an effective and a safe treatment option for iron deficiency anaemia and has an advantage of single administration of high doses without serious adverse effects.

    To assess the effectiveness of weekly and daily schemes of preventive supplementation with supplementary iron to prevent iron deficiency anemia in non-anemic infants. A prospective population study with a quantitative approach and preventive intervention was performed in the city of Viçosa, Southeastern Brazil, in 2007-8. A total of 103 non-anemic children, aged between six and 18 months of age, were selected, corresponding to 20.2% of the children registered with and cared for by Equipes de Saúde da Família (Family Health Teams). Children were divided into two supplementation groups: daily dosage recommended by the Sociedade Brasileira de Pediatria (Brazilian Society of Pediatrics) (group 1, n=34) and weekly dosage recommended by the Brazilian Ministry of Health (group 2, n=69). Assessments were made in the beginning of the study and after six months, with hemoglobin dosage (portable ss-Hemoglobin-meter) and anthropometric and dietary assessments being performed and socioeconomic questionnaire applied. Impact indicators used were prevalence of anemia, hemoglobin variation, adherence to and side effects of supplements. Groups were homogeneous in terms of socioeconomic, biological and before-intervention health variables. After six months of supplementation, higher means of hemoglobin were found in group 1 than in group 2 (11.66; SD=1.25 and 10.95; SD=1.41, respectively, p=0.015); in addition to lower prevalences of anemia (20.6% and 43.5%, respectively, p=0.04). Only 'supplementation time' influenced severe anemia (p=0.009). Statistically significant differences were not found for the 'adherence to supplementation' and 'side effects' variables. The daily dosage recommended by the Sociedade Brasileira de Pediatria was found to be more effective to prevent anemia in infants, when compared to the dosage used by the Ministry of Health. The weekly dosage recommended by the Brazilian government program needs to be reviewed to increase the effectiveness of prevention

    The NIH Office of Dietary Supplements convened a public workshop on iron screening and supplementation in iron-replete pregnant women and young children in 2016 in Bethesda, Maryland. The starting point for the workshop was the recent reports from the US Preventive Services Task Force concluding that there was insufficient evidence to evaluate the benefits and harms associated with iron screening and routine supplementation among asymptomatic pregnant women and young children (6-24 mo old) in the United States. The goal of the workshop was to explore and refine understanding about the existing knowledge gaps and research needs associated with these preventive services for these groups. Given the focus on the United States, planning for the workshop took into account the higher iron status in the United States compared with developing countries and, in turn, included a focus on iron-replete individuals consistent with the U-shaped risk curve for nutrient-health relations. Topic areas included adaptations in iron homeostasis associated with pregnancy and young childhood, the impact of inflammation, measurement of iron status, current estimates of iron status for pregnant women and young children in the United States and in Europe, and emerging evidence suggesting adverse effects associated with iron supplementation of iron-replete individuals. A crosscutting dialogue conducted at the close of the workshop formed the basis for a workshop summary that specified evidence gaps and research needs in a range of areas centered on the relation of these adaptations of iron homeostasis with the response to and risk from iron supplementation as well as the need for indicators informative of the full continuum of iron status and based on health outcomes, not just erythropoiesis. © 2017 American Society for Nutrition.

    Full Text Available The objective of this study was to determine the effects of feeding protein-iron complex (PIC on productive performance and indicators of iron metabolism, hematology parameters, antioxidant and immune status during first 35 days of a calf’s life. Preparation of the complex involved enzymatic hydrolysis of milk casein (serine protease from Yarrowia lipolytica yeast. Iron chloride was then added to the hydrolyzate and lyophilizate. Calves were divided into treated groups: LFe (low iron dose 10 g/day calf of protein-iron complex, HFe (height iron dose 20 g/day calf, and control group. Dietary supplements containing the lower dose of concentrate had a significant positive effect on iron metabolism, while the higher dose of concentrate resulted in increase of total iron binding capacity (TIBC, saturation of transferrin and decrease of and unsaturated iron binding capacity (UIBC, which suggest iron overload. Additionally, treatment with the lower dose of iron remarkably increased the antioxidant parameters, mainly total antioxidant (TAS and glutathione peroxidase activity (GPx. Higher doses of PIC were related to lower total antioxidant status. IgG, IgM, insulin, glucose, TNFα and IGF-1 concentration did not change significantly in either group after supplementation. In practice, the use of protein-iron complex concentrate requires taking into account the iron content in milk replacers and other feedstuffs.

    Background: Despite its known detrimental effects, iron deficiency remains the most common micronutrient deficiency in the world. Many interventions that aim to improve iron status involve physically active populations. Intense aerobic exercise training negatively affects iron status; however, the impact of regular moderate aerobic exercise on the effectiveness of iron supplementation remains unclear. Objective: This study aimed to determine whether aerobic training modifies the assessment of the effectiveness of iron supplementation in improving conventional iron status measures. Design: Seventy-two iron-depleted, nonanemic Chinese women [serum ferritin (sFer) 110 g/L] were included in an 8-wk, partially blinded, randomized controlled trial with a 2 × 2 factorial design including iron supplements (42 mg elemental Fe/d) or placebo and aerobic training (five 25-min sessions/wk at 75-85% of maximum heart rate) or no training. Linear mixed models were used to evaluate the relation between supplement type, training, and changes in iron status over time, measured by sFer, hemoglobin, soluble transferrin receptor (sTfR), and estimated total body iron. Results: After treatment, both the iron-supplemented trained and untrained groups showed significantly improved sFer, sTfR, and body iron values compared with either of the placebo groups. Similarly, trained participants had significantly higher aerobic fitness measures than untrained participants. Training modified the sFer response to supplementation (training by supplement interaction, P = 0.07), with the iron-supplemented trained group having significantly lower sFer than the iron-supplemented untrained group at week 8 (mean ± SD: 31.8 ± 13.5 and 47.6 ± 15.7 μg/L, respectively; P = 0.042), whereas there was no significant difference between the placebo trained and untrained groups (21.3 ± 12.2 and 20.3 ± 7.0 μg/L, respectively; P = 1.00). Conclusions: Regular aerobic training reduces the apparent effectiveness

Given the ability of iron to catalyze redox reactions, iron therapy can be associated with oxidative stress. The lung is uniquely susceptible to oxidative stress, and little is known about the effects of intravenous iron treatment in this organ. This study characterized changes in markers of oxidative/nitrosative stress and inflammation in the lung of non-iron deficient, non-anemic rats treated with five weekly doses (40 mg iron per kg body weight of low molecular weight iron dextran (LMWID, iron sucrose (IS, ferric carboxymaltose (FCM, ferumoxytol (FMX, iron isomaltoside 1000 (IIM, or saline (control. Rats treated with LMWID, FMX, or IIM showed significant changes in most measures of oxidative/nitrosative stress, inflammation, and iron deposition compared to the saline-treated controls, with greatest changes in the LMWID treatment group.

    Full Text Available Iron deficiency is common during infancy and therefore iron supplementation is recommended. Recent reports suggest that iron supplementation in already iron replete infants may adversely affect growth, cognitive development, and morbidity.Normal and growth restricted rat pups were given iron daily (30 or 150 μg/d from birth to postnatal day (PD 20, and followed to PD56. At PD20, hematology, tissue iron, and the hepatic metabolome were measured. The plasma metabolome and colonic microbial ecology were assessed at PD20 and PD56. T-maze (PD35 and passive avoidance (PD40 tests were used to evaluate cognitive development.Iron supplementation increased iron status in a dose-dependent manner in both groups, but no significant effect of iron on growth was observed. Passive avoidance was significantly lower only in normal rats given high iron compared with controls. In plasma and liver of normal and growth-restricted rats, excess iron increased 3-hydroxybutyrate and decreased several amino acids, urea and myo-inositol. While a profound difference in gut microbiota of normal and growth-restricted rats was observed, with iron supplementation differences in the abundance of strict anaerobes were observed.Excess iron adversely affects cognitive development, which may be a consequence of altered metabolism and/or shifts in gut microbiota.

    Iron deficiency is the most common nutritional disorder in the world, and it is the only common nutrient deficiency in industrialised nations. It is thought to be the most common cause of anaemia. Use of iron supplementation in Switzerland has not been previously quantified in detail. We quantified use of iron supplementation from Swiss data and compared it with data from the UK. We assessed the frequency of serum ferritin and haemoglobin tests prior to newly started iron therapy to see whether use was based on documented low iron levels or blood parameters, especially in the case of parenteral iron supplementation. We conducted a retrospective descriptive study of prescription iron supplementation use, and compared use of oral or parenteral iron drugs between Switzerland (CH) and the UK. We retrieved Swiss data from the Swiss Health Insurance Helsana Group, and UK data were from the Clinical Practice Research Datalink (CPRD). The study period was 2012 to 2014. The 3-year prevalence of iron supplementation was 9.4% in Switzerland and 4.4% in the UK. Iron use increased slightly between 2012 and 2014 in both countries (CH +0.3%, UK +0.2%). Recorded parenteral iron administration was roughly a thousand times higher in Switzerland (1.9%) than in the UK in 2014. In Switzerland, iron supplements were mostly given to patients aged 20 to 49 years or older than of 80 years. In the UK, iron supplementation was less frequent in younger people, but more prevalent in the elderly. Prior to a first iron prescription, ferritin tests were done more frequently in Switzerland (oral 67.2%, parenteral 86.6%) than in the UK (oral 43.3%, parenteral 65.5%). Haemoglobin was measured before a new parenteral iron therapy rarely in Switzerland (oral 14.9%, parenteral 11.7%), but frequently in the UK (oral 77.4%, parenteral 85.6%). Iron supplementation is more common in Switzerland than in the UK, particularly parenteral iron supplementation. Haemoglobin measurements prior to a new parenteral

    Functional iron deficiency (FID) is a major cause of persistent anemia in dialysis patients and also contributes to a suboptimal response to erythropoietin (Epo) administration. Vitamin C acts as an enzyme cofactor and enhances mobilization of the ferrous form of iron to transferrin thus increasing its bioavailability. High-dose intravenous vitamin C has been shown to decrease the Epo requirement and improve hemoglobin levels in previous studies. This study assessed the effect of low-dose oral vitamin C on possible reduction in Epo dose requirements in stable hemodialysis patients with FID. This prospective study included 22 stable hemodialysis patients with FID defined as transferrin saturation (T sat) 100 mcg/L with Epo requirement of ≥4000 U/HD session. Patients received oral vitamin C 250 mg daily for 3 months. Hemoglobin, iron and T sat levels were recorded monthly. No one received iron supplementation during the study period. There was a significant reduction in median Epo dose requirement in the 15 patients who completed the study, from 203.1 U/kg/week (95 % CI 188.4-270.6) to 172.8 U/kg/week (95 % CI 160.2-214.8), (P = 0.01). In the seven responders, there was 33 % reduction in Epo dose from their baseline. Despite adjustment of Epo dose, the mean hemoglobin level was significantly increased from 10.1 ± 0.6 to 10.7 ± 0.6 mg/dL (P = 0.03). No adverse effects of oral vitamin C were observed. Daily low-dose oral vitamin C supplementation reduced Epo dose requirements in hemodialysis patients with FID. Limitations of this study include a small sample size and the lack of measurements of vitamin C and oxalate levels. Despite concerns regarding oral vitamin C absorption in dialysis patients, this study indicates vitamin C was well tolerated by all participants without reported adverse effect.

    A number of studies have reported on the effects of iron supplementation in low birth weight infants; however, no systematic review of the available evidence has been conducted to date. Hence, we performed a systematic review of the literature to examine the effects of iron supplementation on hematologic iron status, growth, neurodevelopment, and adverse effects in low birth weight/premature infants. We searched the Cochrane Library, Medline, and PubMed for articles reporting on the effects of iron supplementation in low weight infants. The following search terms were used: "preterm born infant(s)/children"; "preterm infants"; "prematurely born children" "weight less than 1500 g at birth"; "born prematurely"; "low birth weight infant(s)"; "infants born preterm"; "prematurity"; "small-for-gestational age"; "very small gestational age infants"; "iron supplementation"; "iron intake"; "iron supplements"; "ferric and/or ferrous compounds"; and "ferrous sulphate/fumarate/sulfate". A total of 15 studies were identified and included in the systematic review. Supplemental iron was given orally or as an iron-fortified formula in 14/15 studies. The duration of treatment ranged from 1 week to 18 months. Iron supplementation significantly increased hematologic measures of iron status (including hemoglobin, hematocrit, serum ferritin) relative to placebo or over time in most studies. All controlled studies that examined iron-deficiency anemia (IDA)/ID reported a decreased prevalence of IDA/ID with iron supplementation. Dose dependent decreases in the prevalence of IDA/ID were reported in several studies. Of the 5 studies reporting on growth, none found any significant effect on growth-related parameters (length, height, weight, and head circumference). Only 2 studies reported on neurodevelopment; no marked effects were reported. There were no consistently reported adverse effects, including oxidative stress, inhibited nutrient absorption, morbidity, or the requirement for blood

    This meta-analysis compared the effects of dietary intervention versus iron supplementation on biochemical parameters related to the iron nutritional status in humans. The PubMed, CENTRAL, LILACS, SCIELO, OPENGREY.EU and ClinicalTrials.gov databases were searched for randomized clinical trials that assigned individuals to a dietary intervention or to an iron supplementation regimen, for 12 weeks or more. The primary outcome was the hemoglobin concentration, and secondary outcomes were ferritin, RDW, mean corpuscular volume, soluble transferrin receptor, total iron binding capacity, serum iron, and transferrin saturation. From the 6095 records identified, twelve studies were included, six with children, five with adolescents/adults, and one with pregnant women. In the subgroup of studies that included anemic/iron deficient children, supplementation significantly increased the hemoglobin concentration (weighted mean difference (WMD): 3.19 g/L [95% CI: 1.31, 5.07]) and induced a significantly greater reduction of the soluble transferrin receptor (WMD: -0.46 mg/L [95% CI: -0.70, -0, 21]), when compared to dietary intervention. It also induced a greater reduction of the total binding capacity of iron in adolescents/adults (WMD: -6.96 μmol/L [95% CI: -12.70, -1.21]). Supplementation showed a better effect on hemoglobin recovery in anemic/iron deficient children, while no differences were observed between supplementation and dietary intervention in treating adolescents/adults.

    Image quality in an Intravenous Urogram (IVU) can occasionally be compromised by variables like bowel preparation, renal function and radiographic factors, posing a challenge to all Uroradiologists. The Computerised Tomography Urogram (CTU) yields better diagnostic information than an IVU, due to its inherent superior anatomic delineation and contrast sensitivity, against a trade-off involving radiation dose and cost. Our study was conducted to assess the utility and timing of performing a single-phase CTU, as a problem-solving tool, to clear the diagnostic dilemma in a selected subset of patients, in whom an ongoing IVU could potentially be inconclusive. Five hundred and twelve patients who underwent IVU studies for urologic referrals at a tertiary care hospital, during the period of January to December 2009, formed the subject of the study, of whom 33 patients with inconclusive IVU findings after the first three radiographs underwent a single-phase CTU, to reach definitive imaging diagnoses. The percentage of inconclusive IVU studies amounted to only 33 / 512 (6.4%), in whom a CTU study revealed definitive diagnoses in 30 patients and no abnormality in three patients, thus conclusively clearing the ambiguities raised on the IVU in all the selected patients. The concept of a CTU limited to a single-phase study to supplement an inconclusive IVU optimizes the contrast and radiation dose to the affected patients. It is a cost-effective, timely, and definitive 'imaging intervention' and should be considered a viable hybrid technique to be utilized selectively and judiciously.

    Exposure to high altitudes is associated with hypoxia and increased vulnerability to oxidative stress. Polycythemia (increased number of circulating erythrocytes) develops to compensate the high altitude associated hypoxia. Iron supplementation is, thus, recommended to meet the demand for the physiological polycythemia. Iron is a major player in redox reactions and may exacerbate the high altitudes-associated oxidative stress. The aim of this study was to explore the potential iron-induced oxidative lung tissue injury in rats at high altitudes (6000 ft above the sea level). Iron supplementation (2 mg elemental iron/kg, once daily for 15 days) induced histopathological changes to lung tissues that include severe congestion, dilatation of the blood vessels, emphysema in the air alveoli, and peribronchial inflammatory cell infiltration. The levels of pro-inflammatory cytokines (IL-1β, IL-6, and TNF-α), lipid peroxidation product and protein carbonyl content in lung tissues were significantly elevated. Moreover, the levels of reduced glutathione and total antioxidant capacity were significantly reduced. Co-administration of trolox, a water soluble vitamin E analog (25 mg/kg, once daily for the last 7 days of iron supplementation), alleviated the lung histological impairments, significantly decreased the pro-inflammatory cytokines, and restored the oxidative stress markers. Together, our findings indicate that iron supplementation at high altitudes induces lung tissue injury in rats. This injury could be mediated through excessive production of reactive oxygen species and induction of inflammatory responses. The study highlights the tissue injury induced by iron supplementation at high altitudes and suggests the co-administration of antioxidants such as trolox as protective measures. - Highlights: • Iron supplementation at high altitudes induced lung histological changes in rats. • Iron induced oxidative stress in lung tissues of rats at high altitudes. • Iron

    Methods: Groups of experimental rats were maintained on diets supplemented with iron (Molar ratio - Zn:Fe 1:30 and calcium (Molar ratio - Zn:Ca 1:667 both individually and in combination for six weeks. Zinc status of these rats was assessed by determining zinc concentration in circulation and in organs, and the activities of zinc containing enzymes in serum and liver. Results: The zinc status of experimental rats receiving supplemental levels of iron and calcium was significantly compromised. Zinc concentration in serum, kidney, spleen and liver was reduced significantly by both these minerals. Six weeks of supplementation of iron and calcium individually, significantly reduced the activity of liver and serum superoxide dismutase and alkaline phosphatase. Activity of liver alcohol dehydrogenase was lowered in calcium supplemented group and in calcium + iron supplemented group, while that of carbonic anhydrase was significantly reduced by iron, calcium and their combination. Interpretation & conclusions: Supplemental levels of iron and calcium, both individually and in combination, significantly compromised the zinc status of experimental rats. This negative effect of these two minerals was more prominent when these were supplemented for a period of six weeks.

    Iron deficiency anaemia (IDA) is a common complication of inflammatory bowel disease (IBD) associated with reduced quality of life and increased hospitalisation rates. While the best way of treating IDA in IBD patients is not clearly established, current European guidelines recommend intravenous iron therapy in IBD patients with severe anaemia or intolerance to oral iron compounds. To compare the efficacy and tolerability of different intravenous iron formulations used to treat IDA in IBD patients in a systematic review and Bayesian network meta-analysis (NMA), PROSPERO registration number: 42016046565. In June 2016, we systematically searched for studies analysing efficacy and safety of intravenous iron for IDA therapy in IBD. Primary outcome was therapy response, defined as Hb normalisation or increase ≥2 g/dL. Five randomised, controlled trials (n = 1143 patients) were included in a network meta-analysis. Only ferric carboxymaltose was significantly more effective than oral iron [OR=1.9, 95% CrI: (1.1;3.2)]. Rank probabilities showed ferric carboxymaltose to be most effective, followed by iron sucrose, iron isomaltose and oral iron. Pooled data from the systematic review (n = 1746 patients) revealed adverse event rates of 12.0%, 15.3%, 12.0%, 17.0% for ferric carboxymaltose, iron sucrose, iron dextran and iron isomaltose respectively. One drug-related serious adverse event (SAE) each was reported for ferric carboxymaltose and iron isomaltoside, and one possibly drug-related SAE for iron sucrose. Ferric carboxymaltose was the most effective intravenous iron formulation, followed by iron sucrose. In addition, ferric carboxymaltose tended to be better tolerated. Thus, nanocolloidal IV iron products exhibit differing therapeutic and safety characteristics and are not interchangeable. © 2017 John Wiley & Sons Ltd.

    We evaluated the role of dietary iron, heme iron, and supplemental iron on colorectal cancer (CRC) risk in a population-based case-control study in Pennsylvania, including 1005 incident cases and 1062 controls. Diet was assessed through a modified food frequency questionnaire that included supplement use and a meat-specific module. Cases reported intakes for the year before diagnosis, whereas controls reported intakes for the year before interview. Heme iron intake was calculated using a new heme database developed by the US National Cancer Institute. Odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using unconditional logistic regression. After multivariate adjustment, there were no significant associations between heme iron or total iron intake and CRC incidence. Dietary iron intake was inversely associated with CRC among women (OR Q5 vs. Q1=0.45; 95% CI=0.22-0.92), but not among men. Supplemental iron intake of more than 18 mg/day versus none was positively associated with CRC incidence (OR=2.31; 95% CI=1.48-3.59; P-trendconsumption of more than 18 mg/day of supplemental iron may increase risk for CRC.

    Full Text Available Background: Image quality in an Intravenous Urogram (IVU can occasionally be compromised by variables like bowel preparation, renal function and radiographic factors, posing a challenge to all Uroradiologists. The Computerised Tomography Urogram (CTU yields better diagnostic information than an IVU, due to its inherent superior anatomic delineation and contrast sensitivity, against a trade-off involving radiation dose and cost. Our study was conducted to assess the utility and timing of performing a single-phase CTU, as a problem-solving tool, to clear the diagnostic dilemma in a selected subset of patients, in whom an ongoing IVU could potentially be inconclusive. Material and Methods: Five hundred and twelve patients who underwent IVU studies for urologic referrals at a tertiary care hospital, during the period of January to December 2009, formed the subject of the study, of whom 33 patients with inconclusive IVU findings after the first three radiographs underwent a single-phase CTU, to reach definitive imaging diagnoses. Results: The percentage of inconclusive IVU studies amounted to only 33 / 512 (6.4%, in whom a CTU study revealed definitive diagnoses in 30 patients and no abnormality in three patients, thus conclusively clearing the ambiguities raised on the IVU in all the selected patients. Conclusions: The concept of a CTU limited to a single-phase study to supplement an inconclusive IVU optimizes the contrast and radiation dose to the affected patients. It is a cost-effective, timely, and definitive ′imaging intervention′ and should be considered a viable hybrid technique to be utilized selectively and judiciously.

    BACKGROUND Restless legs syndrome (RLS) is a common disorder in hemodialysis (HD) patients that causes sleep disturbances and diminished quality of life. Because iron deficiency has been implicated in the pathogenesis of RLS, we sought to investigate the effects of intravenous (IV) iron sucrose on symptoms of RLS in HD patients. MATERIAL AND METHODS The study was a randomized, placebo-controlled study of 1000 mg iron sucrose versus normal saline as placebo. Patients were evaluated at baseline and 2 weeks after the last injection. The severity of RLS was assessed using the International RLS Study Group rating scale (IRLS). Blood samples were taken to measure iron parameters reflecting the iron status, including serum ferritin (SF) concentration, percentage transferrin saturation (TSAT%) and hemoglobin (Hb), and other biochemical parameters as safety assessments, including creatinine (Cr), urea, intact parathyroid hormone (iPTH), and the index of urea clearance (Kt/V). Adverse events were monitored in all subjects during the period of infusion. RESULTS After 2 weeks, IRLS scores decreased more in the IV-iron group (-7.38±2.03) than in the placebo group (-0.81±2.61) (P=0.000). Serum ferritin, TSAT, and hemoglobin increased more in the IV-iron group (227.63±77.64 µg/L; 26.06±7.77%; 13.98±3.62g/L, respectively) than in the placebo group (SF, p=0.000; TSAT, p=0.000; Hb, p=0.000, respectively). There were no significant differences between IV-iron and placebo groups in Cr, urea, iPTH, and Kt/V. No adverse effects were observed in the study. CONCLUSIONS IV iron sucrose is a safe and effective treatment for reducing RLS symptoms in HD patients over the short-term.

    This report addresses the evidence and the uncertainties, knowledge gaps, and research needs identified by participants at the NIH workshop related to iron screening and routine iron supplementation of largely iron-replete pregnant women and young children (6-24 mo) in developed countries. The workshop presentations and panel discussions focused on current understanding and knowledge gaps related to iron homeostasis, measurement of and evidence for iron status, and emerging concerns about supplementing iron-replete members of these vulnerable populations. Four integrating themes emerged across workshop presentations and discussion and centered on 1 ) physiologic or developmental adaptations of iron homeostasis to pregnancy and early infancy, respectively, and their implications, 2 ) improvement of the assessment of iron status across the full continuum from iron deficiency anemia to iron deficiency to iron replete to iron excess, 3 ) the linkage of iron status with health outcomes beyond hematologic outcomes, and 4 ) the balance of benefit and harm of iron supplementation of iron-replete pregnant women and young children. Research that addresses these themes in the context of the full continuum of iron status is needed to inform approaches to the balancing of benefits and harms of screening and routine supplementation. © 2017 American Society for Nutrition.

    Robert Staroń

    Full Text Available Among livestock, domestic pig (Sus scrofa is a species, in which iron metabolism has been most intensively examined during last decade. The obvious reason for studying the regulation of iron homeostasis especially in young pigs is neonatal iron deficiency anemia commonly occurring in these animals. Moreover, supplementation of essentially all commercially reared piglets with iron entails a need for monitoring the efficacy of this routine practice followed in the swine industry for several decades. Since the discovery of hepcidin many studies confirmed its role as key regulator of iron metabolism and pointed out the assessment of its concentrations in biological fluids as diagnostic tool for iron-related disorder. Here we demonstrate that urine hepcidin-25 levels measured by a combination of weak cation exchange chromatography and time-of-flight mass spectrometry (WCX-TOF MS are highly correlated with mRNA hepcidin expression in the liver and plasma hepcidin-25 concentrations in anemic and iron-supplemented 28-day old piglets. We also found a high correlation between urine hepcidin level and hepatic non-heme iron content. Our results show that similarly to previously described transgenic mouse models of iron disorders, young pigs constitute a convenient animal model to explore accuracy and relationship between indicators for assessing systemic iron status.

    Iron deficiency in infancy is associated with a range of clinical and developmentally important issues. Currently, it is unclear what is the optimal timing to administer prophylactic enteral iron supplementation in preterm and very low birth weight infants. The objective of this meta-analysis was to evaluate early compared with late iron supplementation in low birth weight infants. PubMed and Cochrane Library databases were searched up to May 10, 2014 for studies that compared the benefit of early and late iron supplementation in infants of low birth weight. Sensitivity analysis was carried out using the leave one-out approach and the quality of the included data was assessed. The data base search and detailed review identified four studies that were included in the meta-analysis. The number of included patients was 246 (n=121 for early supplementation and n=125 for late supplementation) and the majority were premature infants. Across studies, early supplementation ranged from as early as enteral feeding was tolerated to 3 weeks, and late supplementation ranged from 4 weeks to about 60 days. Early treatment was associated with significantly smaller decreases in serum ferritin and hemoglobin levels (Psupplementation (P=0.022). There was no difference between early and late supplementation in the number of patients with nectorizing enteroclitis (>bell stage 2) (P=0.646). Sensitivity analysis indicated no one study overly influenced the findings and that the data was reliable. In conclusion, early iron supplementation resulted in less a decrease in serum ferritin and hemoglobin levels in infants with low birth rate. However, caution should be used when treating infants with iron so as not to result in iron overload and possibly negative long-term effects on neurodevelopment.

    Full Text Available ABSTRACT The objective of this study was to evaluate the effect of chelated iron supplementation on gestating and lactating sows and on their suckling and weaned piglets. Reproductive traits, piglet performance, hematological parameters, and the iron concentrations in colostrum, milk, and stillborn livers were measured. Ninety-six sows were subjected to one of three treatment groups. Group T1 comprised pregnant and lactating sows treated with diets supplemented with inorganic iron (551 mg Fe/kg and suckling piglets administered 200 mg of injectable iron dextran. Group T2 was the same as T1, except that sows after 84 days of gestation, lactating sows, and suckling piglets were fed a diet supplemented with 150 mg Fe/kg of chelated iron, and suckling piglets were administered injectable iron dextran. Group T3 was the same as T2 but without injectable iron dextran for suckling piglets. During the nursery phase, all of the weaned piglets were penned with their original groups or treatments and received isonutritive and isocaloric feeds. Piglets from the T2 and T3 groups also received an additional 150 mg Fe/kg of chelated iron via their feed. There were no differences among the treatments for reproductive traits or the iron concentrations in the colostrum, milk, or liver. The piglets that did not receive the injectable iron dextran showed the poorest performance during the pre-and post-weaning phases and showed the poorest hematological parameters of the suckling piglets. The chelated iron supplementation is insufficient to meet piglet demand. The iron dextran supply is necessary for suckling and weaned piglets.

    Full Text Available Iron supplementation reduces the frequency and severity of breath-holding attacks (BHAs, particularly in children with iron deficiency. The issue of iron supplementation is less clear for Westernized children with BHAs who present to an outpatient community clinic and are not iron-deficient. This is the first reported case series of iron-replete children with frequent and disabling breath-holding attacks who have responded to a course of oral iron supplementation. This intervention is safe, improves quality of life for both child and carer, and is significantly cost-effective in terms of health resource utilization.

    Iron deficiency anaemia is a public health problem that affects all age groups. In Mexico, it is a common cause of morbidity, and accounts for 50% of cases of anaemia worldwide. It is more prevalent during the first 2 years of life, during adolescence and pregnancy. It is characterised by fatigue, weakness, pallor and koilonychia. Treatment is based on dietary recommendations and oral and intravenous iron supplements. In this review article, we summarise the characteristics of iron efficiency...

    Ferric Carboxymaltose (FCM), Iron Sucrose (IS) and Oral Iron (OI) are alternative treatments for preoperative anaemia. To compare the cost implications, using a cost-minimization analysis, of three alternatives: FCM vs. IS vs. OI for treating iron-deficient anaemia before surgery in patients with colon cancer. Data from 282 patients with colorectal cancer and anaemia were obtained from a previous study. One hundred and eleven received FCS, 16 IS and 155 OI. Costs of intravenous iron drugs were obtained from the Spanish Regulatory Agency. Direct and indirect costs were obtained from the analytical accounting unit of the Hospital. In the base case mean costs per patient were calculated. Sensitivity analysis and probabilistic Monte Carlo simulation were performed. Total costs per patient were 1827® in the FCM group, 2312® in the IS group and 2101® in the OI group. Cost savings per patient for FCM treatment were 485® compared to IS and 274® compared to OI. A Monte Carlo simulation favoured the use of FCM in 84.7% and 84.4% of simulations when compared to IS and OI, respectively. FCM infusion before surgery reduced costs in patients with colon cancer and iron-deficiency anaemia when compared with OI and IS.

    Full Text Available The recognized antagonistic actions between zinc and iron prompted us to study this subject in children. A convenience sample was used. Thirty healthy children between 8 and 9 years of age were studied with the aim of establishing the effect of a 3-mo oral zinc supplementation on iron status. Fifteen individuals were given a placebo (control group, and 15 were given 10 mg Zn/day (experimental group. Blood samples were collected at 0, 60, 120, 180 and 210 min after a 12-h overnight fast, before and after placebo or zinc supplementation. This supplementation was associated with significant improvements in energy, protein, fat, carbohydrate, fiber, calcium, iron, and zinc intake in accordance with the recommendations for age and sex. The basal serum zinc concentration significantly increased after oral zinc supplementation (p < 0.001. However, basal serum iron concentrations and area under the iron curves significantly decreased in the experimental group (p < 0.0001 and remained at the same level throughout the 210-min study. The values obtained for hemoglobin, mean corpuscular volume, ferritin, transferrin, transferrin saturation, ceruloplasmin and total protein were within normal reference ranges. In conclusion, the decrease in serum iron was likely due to the effects of chronic zinc administration, and the decrease in serum iron was not sufficient to cause anemia.

    Full Text Available Abstract Background In patients treated by maintenance hemodialysis the relationship to survival of hemoglobin level and administered epoetin-alfa and intravenous iron is controversial. The study aim was to determine effects on patient survival of administered epoetin-alfa and intravenous iron, and of hemoglobin and variables related to iron status. Methods The patients were 1774 treated by maintenance hemodialysis in 3 dialysis units in New York, NY from January 1998 to June, 2007. A patient-centered, coded, electronic patient record used in patient care enabled retrospective analysis of data collected prospectively. For survival analysis, patients were censored when transplanted, transferred to hemodialysis at home or elsewhere, peritoneal dialysis. Univariate Kaplan-Meier analysis was followed by multivariate analysis with Cox's regression, using as variables age, race, gender, major co-morbid conditions, epoetin-alfa and intravenous iron administered, and 15 laboratory tests. Results Median age was 59 years, epoetin-alfa (interquartile range 18,162 (12,099, 27,741 units/week, intravenous iron 301 (202, 455 mg/month, survival 789 (354, 1489 days. Median hemoglobin was 116 (110, 120g/L, transferrin saturation 29.7 (24.9, 35.1%, serum ferritin 526 (247, 833 μg/L, serum albumin 39.0 (36.3, 41.5 g/L. Survival was better the higher the hemoglobin, best with > 120 g/L. Epoetin-alfa effect on survival was weak but had statistically significant interaction with intravenous iron. For intravenous iron, survival was best with 1–202 mg/month, slightly worse with 202–455 mg/month; it was worst with no intravenous iron, only slightly better with > 455 mg/month. Survival was worst with transferrin saturation ≤ 16%, serum ferritin ≤ 100 μg/L, best with transferrin saturation > 25%, serum ferritin > 600 μg/L The effects of each of hemoglobin, intravenous iron, transferrin saturation, and serum ferritin on survival were independently significant and

    Full Text Available Background: Iron deficiency is the most prevalent nutritional deficiency in adolescent girls from the developing world. One of the recommended interventions to improve iron status in adolescent girls is iron supplementation. Yet the provision of iron supplements to adolescent girls proved to be a challenging task for the health systems across the developing world. Objective: The objective of the study was to examine means of reaching adolescent girls for iron supplementation in Northern Ethiopia. Methodology: Analytical cross-sectional study consisting of both quantitative and qualitative approaches to data collection and analysis was used in this study. Stratified multi-stage systematic random sampling technique was adopted and primary quantitative data were collected from 828 (578 school attending and 250 non school attending adolescent girls recruited from nine districts of Tigray. The primary quantitative data were analyzed using SPSS version 20 software. The qualitative data collected through key informant interviews and focus group discussions were transcribed verbatim and qualitatively analyzed. Results: The mean (SD age of the girls was 16.7 (1.4 years. Four hundred forty seven (54%, 355 (42.9% and 26 (3.1% of the adolescent girls had low, medium and high diet diversity scores, respectively. More than half, 467 (56%, of the adolescent girls believed that adolescent girls were overloaded with household jobs everyday compared to boys from their respective communities. Key informants said that, there is no adolescent nutrition message promoted in the study area. Low community awareness, perceiving iron tablet as a contraceptive, religious and cultural influences, and lack of confidence in supplementation value of iron tablets, are some of the potential barriers mentioned by the key informant and focus group discussion participants. Schools (45%, health centers (27% and health posts (26% were the preferred public facilities for provision of

    Background Intravenous iron use in hemodialysis patients has greatly increased over the last decade, despite limited studies on the safety of iron. Methods We studied the association of receipt of intravenous iron with hospitalizations in an incident cohort of hemodialysis patients. We examined 9544 patients from Dialysis Clinic, Inc. (DCI). We ascertained intravenous iron use from DCI electronic medical record and USRDS data files, and hospitalizations through Medicare claims. We examined the association between iron exposure accumulated over 1-, 3- or 6-month time windows and incident hospitalizations in the follow-up period using marginal structural models accounting for time-dependent confounders. We performed sensitivity analyses including recurrent events models for multiple hospitalizations and models for combined outcome of hospitalization and death. Results There were 22 347 hospitalizations during a median follow-up of 23 months. Higher cumulative dose of intravenous iron was not associated with all-cause, cardiovascular or infectious hospitalizations [HR 0.97 (95% CI: 0.77–1.22) for all-cause hospitalizations comparing >2100 mg versus 0–900 mg of iron over 6 months]. Findings were similar in models examining the risk of hospitalizations in 1- and 3-month windows [HR 0.88 (95% CI: 0.79–0.99) and HR 0.88 (95% CI: 0.74–1.03), respectively] or the risk of combined outcome of hospitalization and death in the 6-month window [HR 0.98 (95% CI: 0.78–1.23)]. Conclusions Higher cumulative dose of intravenous iron may not be associated with increased risk of hospitalizations in hemodialysis patients. While clinical trials are needed, employing higher iron doses to reduce erythropoiesis-stimulating agents does not appear to increase morbidity in routine clinical care. PMID:25366328

    Iron incorporated into food can induce precipitation and unwanted interaction with other components in food. Iron-binding proteins represent a possibility to avoid these problems and other side effects, as the iron is protected. However, there are several technical problems associated with protein-iron complex formation. In this paper, the iron-binding phosphorylated human-like collagen (Fe-G6P-HLC) was prepared under physiological conditions through phosphorylated modification. One molecule of Fe-G6P-HLC possesses about 24 atoms of Fe. Spectroscopy analysis, differential scanning calorimetry (DSC) and equilibrium dialysis techniques were employed to investigate the characteristics of the Fe-G6P-HLC. The binding sites (nb) and apparent association constant (Kapp) between iron and phosphorylated HLC were measured at nb=23.7 and log Kapp=4.57, respectively. The amount of iron (Fe(2+) sulfate) binding to phosphorylated HLC was found to be a function of pH and phosphate content. In addition, the solubility and thermal stability of HLC were not significantly affected. The results should facilitate the utilization of HLC as a bioactive iron supplement in the food and medical industry and provide an important theoretical evidence for the application of HLC chelates. © 2013.

    Full Text Available To investigate the influence of daily oral iron supplementation on changes in hemoglobin mass (Hbmass and iron parameters after 2-4 weeks of moderate altitude exposure.Hematological data collected from 178 athletes (98 males, 80 females exposed to moderate altitude (1,350-3,000 m were analysed using linear regression to determine how altitude exposure combined with oral iron supplementation influenced Hbmass, total iron incorporation (TII and blood iron parameters [ferritin and transferrin saturation (TSAT].Altitude exposure (mean ± s: 21 ± 3 days increased Hbmass by 1.1% [-0.4, 2.6], 3.3% [1.7, 4.8], and 4.0% [2.0, 6.1] from pre-altitude levels in athletes who ingested nil, 105 mg and 210 mg respectively, of oral iron supplement daily. Serum ferritin levels decreased by -33.2% [-46.9, -15.9] and 13.8% [-32.2, 9.7] from pre-altitude levels in athletes who supplemented with nil and 105 mg of oral iron supplement daily, but increased by 36.8% [1.3, 84.8] in athletes supplemented with 210 mg of oral iron daily. Finally, athletes who ingested either 105 mg or 210 mg of oral iron supplement daily had a greater TII compared with non-supplemented athletes (0 versus 105 mg: effect size (d = -1.88 [-2.56, -1.17]; 0 versus 210 mg: effect size (d = -2.87 [-3.88, -1.66].Oral iron supplementation during 2-4 weeks of moderate altitude exposure may enhance Hbmass production and assist the maintenance of iron balance in some athletes with low pre-altitude iron stores.

    Full Text Available Anemia is the main micronutrient deficiency problem among adolescent girls in Indonesia. Anemia due to iron deficiency often coexists with zinc deficiency. Both iron deficiency anemia and zinc deficiency can increase the risk of obstetric complications among pregnant women i.e. bleeding during labor and post-partum hemorrhage. Iron-folate supplementation among pregnant women had been conducting since long time ago throughout this country; however, effort to improve the nutritional status particularly among adolescent girls prior to pregnancy is still lack behind. Iron and zinc have antagonistic interaction. Therefore it was challenging to alleviate anemia problem among adolescent girls with appropriate ratio of iron-zinc supplementation, and will give a benefit to improve their nutritional status. This study was aimed to investigate the different ratios of ironzinc supplementation on reducing the prevalence of anemia as improving the nutritional status of adolescent school girls.A female elementary school students age 10-12 years old (n= 137 were screened in rural area of Kupang City, East Timor Province. Subjects were assigned randomly to one of the three groups for daily iron-zinc supplementation for 12 weeks; Group 1 (iron; 60 mg/day, Group 2 (iron and zinc; 30 mg and 15 mg/day, Group 3 (iron and zinc; 60 mg and 15 mg/day.

    In infants and young children in Sub-Saharan Africa, iron-deficiency anemia (IDA) is common, and many complementary foods are low in bioavailable iron. In-home fortification of complementary foods using iron-containing micronutrient powders (MNPs) and oral iron supplementation are both effective strategies to increase iron intakes and reduce IDA at this age. However, these interventions produce large increases in colonic iron because the absorption of their high iron dose (≥12.5 mg) is typically iron supplements and iron fortification with MNPs on the gut microbiome and diarrhea. Iron-containing MNPs and iron supplements can modestly increase diarrhea risk, and in vitro and in vivo studies have suggested that this occurs because increases in colonic iron adversely affect the gut microbiome in that they decrease abundances of beneficial barrier commensal gut bacteria (e.g., bifidobacteria and lactobacilli) and increase the abundance of enterobacteria including entropathogenic Escherichia coli These changes are associated with increased gut inflammation. Therefore, safer formulations of iron-containing supplements and MNPs are needed. To improve MNP safety, the iron dose of these formulations should be reduced while maximizing absorption to retain efficacy. Also, the addition of prebiotics to MNPs is a promising approach to mitigate the adverse effects of iron on the infant gut. © 2017 American Society for Nutrition.

    Background Deficiencies of iron and folic acid during pregnancy can lead to adverse outcomes for the fetus, thus supplements are recommended. Adherence to current tablet-based supplements is documented to be poor. Recently a powdered form of micronutrients has been developed which may decrease side-effects and thus improve adherence. However, before testing the efficacy of the supplement as an alternate choice for supplementation during pregnancy, the bioavailability of the iron needs to be determined. Our objective was to measure the relative bioavailability of iron and folic acid from a powdered supplement that can be sprinkled on semi-solid foods or beverages versus a traditional tablet supplement in pregnant women. Methods Eighteen healthy pregnant women (24 – 32 weeks gestation) were randomized to receive the supplements in a crossover design. Following ingestion of each supplement, the changes (over baseline) in serum iron and folate over 8 hours were determined. The powdered supplement contained 30 mg of iron as micronized dispersible ferric pyrophosphate with an emulsifier coating and 600 μg folic acid; the tablet contained 27 mg iron from ferrous fumarate and 1000 μg folic acid. Results Overall absorption of iron from the powdered supplement was significantly lower than the tablet (p = 0.003). There was no difference in the overall absorption of folic acid between supplements. Based on the differences in the area under the curve and doses, the relative bioavailability of iron from powdered supplement was lower than from the tablet (0.22). Conclusion The unexpected lower bioavailability of iron from the powdered supplement is contrary to previously published reports. However, since pills and capsules are known to be poorly accepted by some women during pregnancy, it is reasonable to continue to explore alternative micronutrient delivery systems and forms of iron for this purpose.

    Iron incorporated into food can induce precipitation and unwanted interaction with other components in food. Iron-binding proteins represent a possibility to avoid these problems and other side effects, as the iron is protected. However, there are several technical problems associated with protein–iron complex formation. In this paper, the iron-binding phosphorylated human-like collagen (Fe-G6P-HLC) was prepared under physiological conditions through phosphorylated modification. One molecule of Fe-G6P-HLC possesses about 24 atoms of Fe. Spectroscopy analysis, differential scanning calorimetry (DSC) and equilibrium dialysis techniques were employed to investigate the characteristics of the Fe-G6P-HLC. The binding sites (n b ) and apparent association constant (K app ) between iron and phosphorylated HLC were measured at n b = 23.7 and log K app = 4.57, respectively. The amount of iron (Fe 2+ sulfate) binding to phosphorylated HLC was found to be a function of pH and phosphate content. In addition, the solubility and thermal stability of HLC were not significantly affected. The results should facilitate the utilization of HLC as a bioactive iron supplement in the food and medical industry and provide an important theoretical evidence for the application of HLC chelates. - Highlights: • The iron-binding phosphorylated human-like collagen (Fe-G6P-HLC) was prepared. • One molecule of Fe-G6P-HLC possesses about 24 atoms of Fe. • The binding properties could be modulated through alterations in pH and phosphate content presented in HLC. • A novel strategy for preparing iron-binding proteins was provided

    Iron deficiency anaemia (IDA) is the most common nutritional deficiency in the world including developed and developing countries. Despite intensive efforts to improve the quality of life of rural and aboriginal communities in Malaysia, anaemia and IDA are still major public health problems in these communities particularly among children. A randomized, double-blind, placebo-controlled trial was conducted on 250 Orang Asli (aboriginal) schoolchildren in Malaysia to investigate the effects of a single high-dose of vitamin A supplementation (200,000 IU) on iron status indices, anaemia and IDA status. The effect of the supplement was assessed after 3 months of receiving the supplements; after a complete 3-day deworming course of 400 mg/day of albendazole tablets. The prevalence of anaemia was found to be high: 48.5% (95% CI=42.3, 54.8). Moreover, 34% (95% CI=28.3, 40.2) of the children had IDA, which accounted for 70.1% of the anaemic cases. The findings showed that the reduction in serum ferritin level and the increments in haemoglobin, serum iron and transferrin saturation were found to be significant among children allocated to the vitamin A group compared to those allocated to the placebo group (pvitamin A group compared with only 2.3% reduction among children in the placebo group. In conclusion, vitamin A supplementation showed a significant impact on iron status indices and IDA among Orang Asli children. Hence, providing vitamin A supplementation and imparting the knowledge related to nutritious food should be considered in the efforts to improve the nutritional and health status of these children as a part of efforts to improve the quality of life in rural and aboriginal communities.

    The study was carried out to evaluate the effects of iron and zinc supplementations separated or combined on levels of iron, zinc and insulin like growth factor-1 (IGF-) in prepuberal girls suffering from iron deficiency anaemia. Hematological and biochemical changes of thirty two anaemic prepubertal girls (mean age 10.5 ± 2.01 year) were compared with normal fifteen girls have the same age. The anaemic girls were divided into three groups according to treatment; groupA (iron, group B(zinc) and group C (iron+zinc)and received supplementations for 8 weeks. Significant decreases in erythrocytic counts (RBCs), hemoglobin (Hb), hematocrit % (Hct%) and reticulocytes%(Rt%) were recorded in blood samples of the three groups before supplementations while non-significant differences were detected in the values of other blood indices. Significant decreases were detected in iron, zinc and IGF-1 levels while non-significant decrease in ferritin was detected in group (A). Erythropoietin and total iron binding capacity (TIBC) showed significant increases in the same group. Total iron binding capacity, iron, zinc and IGF-1 levels showed significant decreases while there were significant increases in erythropoetin and ferritin in group (B). The results revealed that ferritin,iron, zinc and IGF-1 levels were significantly decreased while erythropoietin and TIBC were significantly increased in group (C). After treatment, group (B) showed sligh significant increases in the concentration of Hb, Hct% and Rt%. with non-significant increase in RBCs count but in group (C) the results revealed significant increases in RBCs count, Hb, Hct% and Rt%. Non- significant differences were detected in RBCs count, Hb and Hct% in group (A) while significant increase was detected in Rt% in the same group

    Previous studies have compared rates of adverse events between intravenous (IV) iron preparations; however, there has been no comparison of adverse event rates by country and population. To compare rates of adverse events to IV iron products by country and population. All adverse events reported from 18 countries from January 1, 2003 to June 30, 2009 were obtained for iron dextran (ID), iron sucrose (IS), IS similars (ISS), and sodium ferric gluconate (FG). Rates of all adverse events and serious adverse events (anaphylaxis plus other serious allergic reactions) were calculated as number of events per gram of iron sold (gFe) per million inhabitants (mil) × 10-3. Odds ratios (ORs) were calculated for the risks of adverse events between products. Iron use ranged from 1 gFe/mil (Poland) to 48,674 gFe/mil (Italy). Rates of all adverse events (reports/gFe/mil × 10-3) varied: for IS, it ranged from 0 (Poland, Austria, Czech Republic) to 1,222 (Ireland); for FG, from 3.3 (Czech Republic) to 183.6 (United States); for ID, from 0.9 (Turkey) to 46,875 (Switzerland). There were no reports of adverse events in ISS. In a subset of countries that used 2 or more iron products and had more than 1 serious adverse event, rates (reports/gFe/mil × 10-3) of all adverse events and serious adverse events were lowest for IS (39.8 and 1.7), intermediate for FG (54.8 and 4.5), and greatest for ID (337.7 and 20.5). IS had lower risks for all adverse events (OR, 0.63; PID. FG had lower risks for all adverse events (OR, 0.20; PID. Considerable international variation existed in the extent and choice of iron product and adverse event reporting, suggesting under-reporting in some instances. Clinicians should appreciate the differential risks between available products, and should critically review local reporting practices.

    To test the utility of zinc protoporphyrin to heme ratio (ZnPP/H) as an indicator of iron status in premature infants and to evaluate the effect of oral iron supplements on oxidative injury. We hypothesized that iron sulfate supplementation would decrease the ZnPP/H in preterm infants. Infants eligible for this prospective study were: hospitalized, 24 to 32 weeks of gestation, 7 to 60 days old, feeding > or = 70 mL/kg/d, with a ZnPP/H > or = the mean for age. Iron dose was determined by the ZnPP/H. Iron status and oxidative injury were evaluated at study entry and completion. Concurrent control subjects met entry criteria but were not enrolled and were not treated with iron during the study interval. Statistical evaluation included repeated measures analysis of variance and Z-score conversions. Entry ZnPP/H of iron-treated subjects (n = 16) and control subjects (n = 16) were not different. The ZnPP/H of iron-treated infants was lower at study end (P ZnPP/H, is tolerated, and is not associated with increased oxidative injury.

    Antenatal iron supplementation is a cost effective way of reducing iron deficiency anaemia among pregnant women in resource limited countries like Uganda. Poor adherence to iron supplements has limited its effectiveness in reducing maternal anaemia as evidenced by the high burden of iron deficiency anemia in Sub-saharan Africa. The aim of this study was to determine the level of and factors associated with adherence to iron supplementation among women attending antenatal clinic at Mulago National Referral Hospital, Kampala, Uganda. Three hundred and seventy pregnant women were recruited in a cross sectional survey in Mulago National Referral Hospital antenatal clinic after informed consent between February and April 2014. Levels of adherence to iron supplements were assessed using visual analogue scale and factors associated collected using an interviewer administered questionnaire. About 12% (11.6%) of the mothers attending the antenatal clinic adhered to iron supplements over 30 day period. Mothers who had had four or more antenatal visits prior to the survey [odds ratio (OR) = 1.49, 95% confidence interval (CI) 1.12-1.97], had more than 2 week supply of iron supplements in the previous visit (OR 2.81, 95% CI 1.02-1.09), prior health education (OR 1.56, 95% CI 1.07-2.29) were more likely to adhere to iron supplements. Inadequate drug supplies and fear for side effects were the main reasons why participants missed the iron supplements. There was low adherence to iron supplements among mothers attending antenatal clinic at Mulago National Referral  Hospital. We recommend a national evaluation of adherence to iron supplements and look at ways of increasing adherence.

    To investigate the effect of vitamin A (VA) supplementation on the nutritional status of iron in healthy adults. One hundred and fifteen healthy adults were recruited and divided randomly into four groups, with 28 or 29 adults in each group. VA supplements with different doses of retinyl acetate in capsules were given for 4-month. The equivalent doses of supplemented retinyl acetate were 600 microg/d, 400 microg/d, 200 microg/d and 0 microg/d (control) of retinol, respectively. The capsules were administered orally by double blind method. During the experiment, the subjects kept their usual dietary pattern but avoided high VA or pre-VA carotenoids foods from their diets. A 24-h dietary recall was carried out monthly on every subject. Before and after the intervention, the fast blood samples were collected from each subject, and were determined for hemoglobin concentration, levels of serum retinol, iron, ferrtin and transferrtin receptor. Total 108 subjects finished the experiment, with 27, 28, 27 and 26 persons left in group A, B, C and D, respectively. The subjects from each group had similar dietary intakes of energy nutrients, VA and iron (both were P > 0.05) during the experimental period. The serum retinol concentration of subjects from group A increased from 1.63 +/- 0.55 micromol/L of baseline to 1.93 +/-0.52 micromol/L at the end of the experiment (P 0.05). There was no significant difference on Hb concentration before and after the experiment as well as between groups (all were P > 0.05). In subjects of group A, serum iron concentration increased (P supplement intervention. No such changes were observed in group B and C (P supplement with relative high dose of retinol at dietary level could enhance the iron status further in no-anemic healthy adults even without dietary iron supplementation.

    During the second year of the "Iron-like Turkey" Project, in which all children aged 4-6 months in Turkey receive iron supplementation for 5 months, we aimed to assess the utilization of iron supplementation in the field, as well as the prevalence of anemia in healthy infants aged 12-23 months, while determining a variety of sociodemographic and nutritional factors for anemia in three of the 12 NUTS (Nomenclature of Territorial Units for Statistics) regions (regions with the highest, lowest and middle under-5 malnutrition levels). In a community-based, cross-sectional survey using a multi-staged, weighted, cluster-selected sample, children aged 12-23 months with birthweight ≥2500 g, no chronic illness, no history of blood disease, and from term and singleton pregnancy were enrolled; 1589 children met the criteria. The mean±SD age of children surveyed was 17.8±3.6 months. Of the parents, 72.4% claimed that their physician had recommended iron supplementation, and 68.8% had given supplementation to their children. Overall prevalence of anemia was 7.3%. Multivariate analysis revealed that the frequency of anemia decreased significantly in older infants, when supplementation was recommended by health providers, when an infant was breastfed longer than 6 months, and when the mother received iron supplementation during pregnancy. However, anemia prevalence increased when the infant received iron supplementation at a later age (³9 months), lived in a crowded family (³6 persons), and when the mother had a history of iron deficiency anemia. Anemic infants had significantly lower z scores of weight for age than non-anemic ones. This survey suggests that iron supplementation during pregnancy, initiation of iron supplementation in infants at 4-6 months of age, effective counseling on supplementation, subsequent compliance, support of breastfeeding, and effective training of health care personnel are effective strategies for prevention of anemia in the community.

    Evidence on the role of intravenous iron (IVI) supplementation after colorectal cancer (CRC) surgery is rather scant. This study was aimed at assessing the benefit of postoperative IVI administration after elective CRC surgery at our institution. This was a single-centre, retrospective observational study including all patients who underwent CRC surgery during 2014. Anaemia was defined as a haemoglobin (Hb) <13 g/dL, regardless of gender. Anaemic patients received 200 mg IVI up to three times a week to cover iron deficiency (IVI group). Those who did not receive IVI were placed on standard care (NIVI group). The primary outcome was the proportion of anaemic patients on post-operative day (POD)1 and POD30. Secondary outcomes included Hb changes from POD1 to POD30, transfusion requirements and complication rates. Of the 159 patients studied, 139 (87%) presented with anaemia: 47 (34%) of these received post-operative IVI and 92 (66%) did not. Patients in the IVI group had lower POD1 Hb levels compared to those in the NIVI group (p=0.001). On POD30, only 103 had their Hb measured (34 IVI, 69 NIVI). Anaemia was more prevalent and more severe among the patients in the IVI group (p=0.027), despite their greater increment in Hb (2.0±1.5 g/dL vs 1.1±1.2 g/dL; p=0.001). Eleven patients needed post-operative transfusions (7 IVI, 4 NIVI; p=0.044). There were no differences in post-operative complication rates between the groups. No IVI-related adverse events were recorded DISCUSSION: Compared with standard care, post-operative IVI administration to anaemic patients improved the recovery of Hb levels at POD30, without increasing post-operative complications.

    Background Approximately 600 million children of preschool and school age are anaemic worldwide. It is estimated that half of the cases are due to iron deficiency. Consequences of iron deficiency anaemia during childhood include growth retardation, reduced school achievement, impaired motor and cognitive development, and increased morbidity and mortality. The provision of daily iron supplements is a widely used strategy for improving iron status in children but its effectiveness has been limited due to its side effects, which can include nausea, constipation or staining of the teeth. As a consequence, intermittent iron supplementation (one, two or three times a week on nonconsecutive days) has been proposed as an effective and safer alternative to daily supplementation. Objectives To assess the effects of intermittent iron supplementation, alone or in combination with other vitamins and minerals, on nutritional and developmental outcomes in children from birth to 12 years of age compared with a placebo, no intervention or daily supplementation. Search methods We searched the following databases on 24 May 2011: CENTRAL (2011, Issue 2), MEDLINE (1948 to May week 2, 2011), EMBASE (1980 to 2011 Week 20), CINAHL (1937 to current), POPLINE (all available years) and WHO International Clinical Trials Registry Platform (ICTRP). On 29 June 2011 we searched all available years in the following databases: SCIELO, LILACS, IBECS and IMBIOMED. We also contacted relevant organisations (on 3 July 2011) to identify ongoing and unpublished studies. Selection criteria Randomised and quasi-randomised trials with either individual or cluster randomisation. Participants were children under the age of 12 years at the time of intervention with no specific health problems. The intervention assessed was intermittent iron supplementation compared with a placebo, no intervention or daily supplementation.

    Iron deficiency leading to low hemoglobin concentration (cHb) is a common problem for blood donors as well as for blood banks. A standardized protocol offering iron supplementation based on P-ferritin determination may help to reduce the problem and retain donors. This was a prospective study where 879 blood donors, presenting with cHb at or below the limit of acceptance for donation, were included. The predonation cHb result was read after donation. The donors received 50 iron tablets (JernC or Ferrochel, 100 or 25 mg elemental iron, respectively), and samples for P-ferritin, mean corpuscular volume, and control of cHb were secured. Based on a P-ferritin level of less than 60 microg per L, 20 iron tablets were offered after all following donations. Mean cHb was 7.6 mmol per L (122 g/L) and 8.2 mmol per L (132 g/L) in women and men, respectively. In 80 percent of the women and 48 percent of the men, iron stores were low (P-ferritin protocol offering iron supplementation and simple oral and written advice based on P-ferritin measurements is effective in normalizing cHb and retaining donors presenting with cHb at or below the limit of acceptance for donation.

    A 1.8 ml iron supplementation of ferrous sulfate is administered for 90 days to 76 Mapuche infants, 12 months of age, male and female, from the rural area of the Cautin province of Chile. The iron nutrition is evaluated before and after the supplementation, through: hemoglobin, haematocrit, transferrin saturation and seric ferritin. Stools test are taken at the infant's home, to confirm the supplement intake and to measure the iron excreted. To study the contained of dietary Fe a Recordatory 24 hour Inquest (RI) is applied moreover a Proximal Chemical Analysis (PCHA) to meal test proceeding from the infant's homes. At 12 months before starting the supplementation, the anemia prevalence was of 28.3%, but it disappear as a result of the intervention. Also 65.3% of the infants showed and increase of 1 g or more on their hemoglobin, which indicates that they were anemic at the beginning of the iron supplementation. By means of this therapeutic test it was find 31% more of anemic infants, indicating more sensibility of this method. The high levels of anemia prevalence are due to the low iron intake, characteristic of the non lactious foods, which according results of the RI reaches an average of 2.8 +/- 1.2 mg of Fe/day, versus 4.8 +/- 4.0 mg of Fe/day according to PCHA. The observed difference between both test showed that there is a process of food environmental contamination, by the use of iron utensils and great soil contact. The high environmental contamination could also be proved by the high iron excretion stools (140 mg of Fe/100 g of stools). This method used to measure the Fe excretion of the supplement, would not be valid in rural population groups with similar characteristics to those of the studied group, because it does not discriminate between the intake and the extremely high environmental contamination. To prevent anemia due to iron absence in infants, it is absolutely necessary to have some iron fortified food starting at 6 months of age, as a

    The aim of this study was to analyze the effect of supplementation with cranberry ( Vaccinum macrocarpon ) on the levels of pro-inflammatory cytokines, hepcidin and selected markers of iron metabolism in rowers subjected to exhaustive exercise. This double-blind study included 16 members of the Polish Rowing Team. The subjects were randomly assigned to the supplemented group ( n  = 9), receiving 1200 mg of cranberry extract for 6 weeks, or to the placebo group ( n  = 7). The participants performed a 2000-m test on a rowing ergometer at the beginning and at the end of the preparatory camp. Blood samples were obtained from the antecubital vein prior to each exercise test, one minute after completing the test, and after a 24-h recovery period. The levels of hepcidin, interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-alpha), ferritin, iron, soluble transferrin receptor (sTfR) and myoglobin were determined, along with total iron-binding capacity (TIBC), unbound iron-binding capacity (UIBC) and total antioxidant capacity (TAC). Both prior and after the supplementation, a significant post-exercise increase in the concentration of IL-6 was observed in both groups. At the end of the study period, cranberry-supplemented athletes presented with significantly higher resting, post-exercise and post-recovery levels of TAC than the controls. However, a significant exercise-induced increase in the concentrations of TNF-alpha, myoglobin and hepcidin was observed solely in the control group. Supplementation with cranberry extract contributed to a significant strengthening of antioxidant potential in individuals exposed to strenuous physical exercise. However, supplementation did not exert direct effects on other analyzed parameters: inflammatory markers and indices of iron metabolism (TNF-alpha, hepcidin and myoglobin).

    Full Text Available Aim of the study: To evaluate semen parameters and to assess serum FSH, LH, Testosterone (T concentrations before and 12 weeks after intravenous iron therapy (800-1200 mg elemental iron therapy - IVI in adults with iron-deficiency anemia (IDA. Materials and Methods: We studied 11 eugonadal adults with IDA, aged 40 ± 5 years, due to defective intake of iron. Anemia was diagnosed when hemoglobin (Hb was equal or below 10 g/dl. Serum iron, total iron-binding capacity (TIBC and ferritin concentrations confirmed the diagnosis of IDA. Basal serum concentrations of FSH, LH, and T were measured. Semen parameters were evaluated before and 6-7 weeks after IVI therapy. Results: After IVI therapy and correction of anemia, a significant increase of Hb from 8.1 ± 1.17 g/dL to 13.1 ± 0.7 g/dL was observed and was associated with an increase of T (from 12.22 ± 1.4 nmol/L to 15.9 ± 0.96 nmol/L; P < 0.001, FSH (from 2.82 ± 0.87 to 3.82 ± 1.08 IU/L; P = 0.007, and LH (from 2.27 ± 0.9 to 3.82 ± 1.5 IU/L; P = 0.0002. Total sperm count (TSC increased significantly from 72 ± 17.5 million/ml to 158 ± 49 million/mL (P < 0.001, rapid progressive sperm motility (RPM increased from 22 ± 9.4 to 69 ± 30 million/ml (P < 0.001, and sperms with normal morphology (NM increased from 33 ± 5 to 56 ± 7 million/ml (P < 0.001. Increment in Hb concentration was correlated significantly with LH, FSH, and T concentrations after IVI (r = 0.69 and r = 0.44, r = 0.75, respectively; P < 0.01. The increment in serum T was correlated significantly with increments in the TSC and total sperm motility and RPM (r = 0.66, 0.43, and 0.55, respectively; P < 0.001 but not with gonadotrophin levels. Conclusion: Our study proved for the first time, to our knowledge, that correction of IDA with IVI is associated with significant enhancement of sperm parameters and increased concentrations of serum LH, FSH, and T. These effects on spermatogenesis are reached by an unknown mechanism and

    Anemia is a frequent problem in both the primary and secondary health care programs. In contrast, most areas of northeast India are vulnerable to iron toxicity. In the present study, we documented the effect of administration of iron rich water on hemolytic anemia in a Wistar rats' animal model. Hemolytic anemia was induced by phenyl hydrazine through intraperitoneal route and diagnosed by the lowering of blood hemoglobin. After inducing the hemolytic anemia, 24 Wistar rats (n = 6 in four groups) were randomly assigned to 1 mg/l, 5 mg/l, and 10 mg/l ferric oxide iron along with 1 mg/ml ascorbic acid administered through drinking water; a control group was treated with iron-free water. The hematological and biochemical parameters, iron levels in liver, spleen, and kidney were estimated after 30 d of treatment. In the group treated with 5 mg/l iron and ascorbic acid, a significant increase of serum iron and ferritin, and a decrease of TIBC (total iron binding capacity) were observed without changes in other biochemical parameters and histopathological findings. However, in the group treated with 10 mg/l iron and ascorbic acid, hematological changes with significantly higher values for white blood cell count, serum glutamic phospho transaminase, serum glutamic oxaloacetic transaminase, alkaline phosphatase, glucose, splenic, and liver iron content, indicate potential toxicity at this supplementation level. Data suggest that the optimum concentration of iron (5 mg/l) and ascorbic acid solution may improve anemic conditions and may be therapeutically beneficial in the treatment of iron deficiency anemia without any negative impact, while 10 mg/l in drinking water seems to be the threshold for the initiation of toxicity.

    How to improve iron status among infants and young children is of continued concern in low- to middle-income countries, including Brazil. In a double blind, 5-mo, home-based, randomized trial in Brazil, we gave one group of mildly anemic 6- to 24-mo-old children (n = 175) rice fortified with micronized ferric pyrophosphate using the Ultra Rice technology and a placebo solution (URG) and another group identical nonfortified rice and iron drops. We instructed parents on the correct dosage of iron drops and to feed their children rice as they normally would. We measured serum ferritin (SF) and hemoglobin (Hb) concentrations at baseline and at 5 mo. At baseline, the prevalences of iron deficiency and anemia in the total sample were 73.1 and 100%, respectively. At 5 mo, SF and Hb increased in both groups, although the change in the URG was larger (P iron stores and reduced anemia in a group of mildly anemic children 6-24 mo old. In populations where young children are routinely fed approximately 100 g of cooked rice daily, fortifying it with iron may improve iron status at least as well as providing free iron drops.

    The literature on the iron requirements of exclusively breastfed infants contains conflicting data and contrary views. The purpose of this study was to summarize the evidence for both benefits and risks of daily oral iron supplementation with regard to hematologic, growth, cognitive parameters, and adverse effects in exclusively breastfed infants. Structured electronic searches were conducted using PubMed, Cochrane Library databases, and Google Scholar for randomized controlled trials (RCTs) involving daily iron supplementation in full-term healthy exclusively breastfed infants. Random- and fixed-effects models were used for calculating the pooled estimates. Four RCTs with 511 infants were included in the meta-analysis. Iron interventions had no significant effect on iron deficiency or iron deficiency anemia, serum ferritin level, or hemoglobin level. Iron interventions did result in a significant increase in Bayley psychomotor developmental indices in later life (mean difference [MD] = 7.00, confidence interval [95% CI] 0.99-13.01) and mean corpuscular volume (MD = 2.17 fL; 95% CI 0.99-3.35 fL). Iron supplementation was associated with slower growth during the exclusive breastfeeding period, but the long-term effect is unclear. Limited available evidence suggests that daily iron supplementation has beneficial effects on hematologic parameters and cognitive development, but may delay physical growth in healthy exclusively breastfed infants. There was no evidence to suggest that iron supplementation could cause other adverse effects.

    A 23 year-old black male with homozygous sickle cell disease (Hb SS disease) and transfusional iron overload was admitted for evaluation of response to intravenous deferoxamine (DFO) therapy. Soon after admission, the patient suffered an intraventricular hemorrhage and during his subsequent hospitalization developed a persistent fever of undetermined origin (f.u.o.). Included in the diagnostic evaluation of fever was a gallium 67 scan (Ga-67), which was initially nondiagnostic because of Ga-67 citrate's preferential chelation by DFO. After DFO was discontinued, a repeat scan demonstrated a lesion above the left kidney. To our knowledge the unusual interaction in vivo of DFO with Ga-67 citrate has not been reported in the clinical literature. With the anticipated increased use of chelation therapy for patients with transfusional iron overload, this interaction may be encountered more frequently. DFO should be discontinued before the use of Ga-67 scanning in this clinical situation, or an alternative isotopic scan, such as indium-labelled white cells, should be considered.

    Iron deficiency anaemia (IDA) is the most common nutritional deficiency in the world including developed and developing countries. Despite intensive efforts to improve the quality of life of rural and aboriginal communities in Malaysia, anaemia and IDA are still major public health problems in these communities particularly among children. A randomized, double-blind, placebo-controlled trial was conducted on 250 Orang Asli (aboriginal) schoolchildren in Malaysia to investigate the effects of a single high-dose of vitamin A supplementation (200,000 IU) on iron status indices, anaemia and IDA status. The effect of the supplement was assessed after 3 months of receiving the supplements; after a complete 3-day deworming course of 400 mg/day of albendazole tablets. The prevalence of anaemia was found to be high: 48.5% (95% CI = 42.3, 54.8). Moreover, 34% (95% CI = 28.3, 40.2) of the children had IDA, which accounted for 70.1% of the anaemic cases. The findings showed that the reduction in serum ferritin level and the increments in haemoglobin, serum iron and transferrin saturation were found to be significant among children allocated to the vitamin A group compared to those allocated to the placebo group (p Orang Asli children. Hence, providing vitamin A supplementation and imparting the knowledge related to nutritious food should be considered in the efforts to improve the nutritional and health status of these children as a part of efforts to improve the quality of life in rural and aboriginal communities.

Main data inputs were based on bibliography and validated by clinicians. The economic evaluation was conducted for inpatients (ie, surgical patients or patients hospitalized due to a disease related to chronic or acute blood loss and outpatients (eg, nondialysis chronic kidney disease patients, separately. Analysis was carried out from a National Health Service (NHS perspective and also from a patient perspective. Total cost treatment reflects the cost of drugs, the cost of all resources expended in patient management such as the cost of disposables for each infusion, the monitoring costs during infusion (salaries of personnel, other hospital expenses, the cost for management of adverse events, the productivity loss, and the traveling cost for patients.Results: In the case of outpatients, the mean total cost per patient in the FCM arm was €198.6, in the IS arm €627.7, and in the LMWID arm, €510.5. For inpatients the mean total cost was estimated at €189.2 for FCM while it was €419.9 and €228.8 for IS and LMWID, respectively.

    The National Service Framework advocates correction of anaemia in patients with chronic kidney disease (CKD). Oral iron is insufficient, while intravenous (IV) supplementation replenishes and maintains iron stores. In Yorkshire numerous peripheral clinics exist to reduce travel for patients, but patients must travel to the main unit for IV iron therapy. Therefore an outpatient service in tandem with a routine clinic for administration of IV CosmoFer was created. To evaluate the feasibility and benefits of IV iron therapy in the outpatient clinic during active patient review for CKD patients. A cross-sectional study of patients attending for total dose IV iron (n = 57) at a peripheral clinic. Iron was administered and monitored according to protocol by one of the clinic nurses with medical staff available in the adjoining room. Haemoglobin, ferritin and renal function were recorded pre-infusion and after 4-6 months. Results are given as medians/means +/- standard error. A total of 76 IV infusions were carried out with no reported side effects or haemodynamic instability. Haemoglobin (median 10.9 vs. 11.3 g dL(-1), P = NS), creatinine and estimated glomerular filtration rate (eGFR) over the 6-month period remained stable. Serum ferritin rose significantly [80.9 +/- 6.2 vs. 186.4 +/- 18.2 g L(-1) (P < 0.001)]. Hospital time saved 380 day case bed hours, doctor hours saved 76 hours, and patient hours saved 3 hours/patient. Cost savings for TDI CosmoFer in peripheral clinic versus in centre therapy and versus sucrose, respectively, for 76 treatments was pound 5749.40 and pound 46,320.80 respectively. We have demonstrated, in a resource-limited service, the feasibility and cost-effectiveness of a management care pathway for patients with CKD, in a peripheral clinic, to receive total dose IV CosmoFer without disruption of a functioning renal clinic.

    Objective: To understand the prevalence of prenatal supplementations of iron, iron-containing multi-micronutrients (IMMN) and antianemic Chinese patent medicines (ACPM) and associated factors in women in Shaanxi province. Methods: A sample of 28 367 childbearing-age women who gave birth during 2010-2013 and had specific information of the prenatal nutrients supplementation were recruited using stratified multistage cluster random sampling in Shaanxi province. The information about their basic characteristics and prenatal supplementation of nutrients were collected by a questionnaire survey. Descriptive analysis method was used to analyze the intake rate of iron, IMMN and ACPM during each period of pregnancy, and logistic regression model was used to identify associated factors. Results: The overall prevalence of prenatal iron, IMMN and ACPM supplementation was low (28.99%), and the intake rate of iron was the lowest (5.33%). The prevalence of prenatal supplementation of iron, IMMN and ACPM were lower before pregnancy and in the first trimester than in the second and third trimester. The intake rates for consecutive 2 periods were very low (all were lower than 2.00%). The intake rates of iron, IMMN and ACPM significantly increased year by year. Women living in central Shaanxi had relatively high intake rates of iron (7.22%) and IMMN (16.55%), and women in southern Shaanxi had relatively high intake rate of ACPM (18.50%). The results of logistic regression analysis showed that higher educational level ( OR =1.920, 95 %CI : 1.617-2.279), antenatal care times≥6 ( OR =1.832, 95 %CI : 1.604-2.091), etc . were the positive factors for iron intake, and these positive factors were similar to those for IMMN intake. Additionally, rural residence was the negative factor for IMMN intake (compared with urban residence, OR =0.872, 95 %CI : 0.788-0.966). Conversely, higher educational level ( OR =0.855, 95 %CI : 0.746-0.979), higher household income ( OR =0.864, 95 %CI : 0

    Although it is expected that accumulation of metal oxide nanoparticles that can induce redox reaction in the biological system may influence ion homeostasis and immune regulation through generation of free radicals, the relationship is still unclear. In this study, mice received magnetic iron oxide nanoparticles (M-FeNPs, 2 and 4 mg/kg) a single via the tail vein, and their distribution in tissues was investigated over time (1, 4, and 13 weeks). In addition, we evaluated the effects on homeostasis of redox reaction-related elements, the ion environment and immune regulation. The iron level in tissues reached at the maximum on 4 weeks after injection and M-FeNPs the most distributed in the spleen at 13 weeks. Additionally, levels of redox reaction-related elements in tissues were notably altered since 1 week post-injection. While levels of K(+) and Na(+) in tissue tended to decrease with time, Ca(2+) levels reached to the maximum at 4 weeks post-injection. On 13 weeks post-injection, the increased percentages of neutrophils and eosinophils, the enhanced release of LDH, and the elevated secretion of IL-8 and IL-6 were clearly observed in the blood of M-FeNP-treated mice compared to the control. While expression of antigen presentation related-proteins and the maturation of dendritic cells were markedly inhibited following distribution of M-FeNPs, the expression of several chemokines, including CXCR2, CCR5, and CD123, was enhanced on the splenocytes of the treated groups. Taken together, we suggest that accumulation of M-FeNPs may induce adverse health effects by disturbing homeostasis of the immune regulation and ion environment.

    Full Text Available Deficiencies of iron and zinc are associated with delayed development, growth faltering, and increased infectious disease morbidity during infancy and childhood. Combined iron and zinc supplementation may therefore be a logical preventive strategy. Objective: the objective of the study was to compare the effects of combined iron and zinc supplementation in infancy with the effects of iron and zinc as single micronutrients on growth, psychomotor development, and incidence of infectious disease. Design: Indonesian infants (n = 680 were randomly assigned to daily supplementation with 10 mg Fe (Fe group, 10 mg Zn (Zn group, 10 mg Fe and 10 mg Zn (Fe + Zn group, or placebo from 6 to 12 mo of age. Anthropometric indexes, developmental indexes (bay ley scales of infant development; sid, and morbidity were recorded. Results: at 12 mo, two factor analysis of variance showed a significant interaction between Iron and Zinc for weight for age z score, knee heel length, and sid psychomotor development. Weight forage z score was higher in the Zn group than in the placebo and Fe + Zn groups, knee heel length was higher in the Zn and Fe groups than in the placebo group, and the sid psychomotor development index was higher in the Fe group than in the placebo group. No significant effect on morbidity was found. Conclusions: single supplementation with zinc significantly improved growth, and single supplementation with iron significantly improved growth and psychomotor development, but combined supplementation with iron and zinc had no significant effect on growth or development. Combined, simultaneous supplementation with iron and zinc to infants cannot be routinely recommended at the iron to zinc ratio used in this study.Key words: infants, growth, knee heel length, development, iron, zinc.

    The effects of Spirulina maxima supplementation on calcium, magnesium, iron, and zinc status were studied in a double-blind placebo-controlled trial of 50 obese subjects with treated hypertension, each randomized to receive 2 g of spirulina or a placebo daily for 3 months. At baseline and after treatment, the calcium, magnesium, iron, and zinc concentration in plasma was assessed. It was found that 3 months of S. maxima supplementation resulted in a significant decrease in the iron level in the plasma of obese patients. In conclusion, this is the first clinical study on the influence of spirulina supplementation on mineral status in obese patients with hypertension. Spirulina supplementation affects the iron status of obese Caucasians with well-treated hypertension.

    Full Text Available Aim: In spite of special supplemental programs for infants, iron deficiency anemia remains relatively common, depending on ethnicity and socioeconomic status. In Turkey, free iron supplement (IS to infants started in 2004. The aim of this current study is to evaluate the IS in infants. Materials and Methods: Between October 2014 and June 2015, a survey to evaluate the prophylactic use of iron in infants was applied at the polyclinics to the mothers of children aged 6-24 months. Results: Two hundred children were included in the study. IS was not given to 16% of the children. There was no difference in the time of attendance of IS between the premature and mature infants. Only 29% of the children had been given IS for longer than 6 months. While 36% of the children stopped receiving IS due to negligence, 8.5% of them stopped getting it it because of the adverse effect of the drug, and 39.5% of them were informed that IS had been stopped by the doctors. Advisable supplement dosage was used in 40% of the children. Conclusion: A low ratio of reasonable attendance time and dosage for prophylaxis was found. A total of 58 children had used IS for longer than 6 months and for 48 of them (82.7% IS had been stopped by the doctor. It was thought that regularly examining a healthy child in infancy augmented the attendance time of IS.

  15. The Pharmacokinetics and Pharmacodynamics of Iron Preparations

    Directory of Open Access Journals (Sweden)

    Susanna Burckhardt

    2011-01-01

    Full Text Available Standard approaches are not appropriate when assessing pharmacokinetics of iron supplements due to the ubiquity of endogenous iron, its compartmentalized sites of action, and the complexity of the iron metabolism. The primary site of action of iron is the erythrocyte, and, in contrast to conventional drugs, no drug-receptor interaction takes place. Notably, the process of erythropoiesis, i.e., formation of new erythrocytes, takes 3−4 weeks. Accordingly, serum iron concentration and area under the curve (AUC are clinically irrelevant for assessing iron utilization. Iron can be administered intravenously in the form of polynuclear iron(III-hydroxide complexes with carbohydrate ligands or orally as iron(II (ferrous salts or iron(III (ferric complexes. Several approaches have been employed to study the pharmacodynamics of iron after oral administration. Quantification of iron uptake from radiolabeled preparations by the whole body or the erythrocytes is optimal, but alternatively total iron transfer can be calculated based on known elimination rates and the intrinsic reactivity of individual preparations. Degradation kinetics, and thus the safety, of parenteral iron preparations are directly related to the molecular weight and the stability of the complex. High oral iron doses or rapid release of iron from intravenous iron preparations can saturate the iron transport system, resulting in oxidative stress with adverse clinical and subclinical consequences. Appropriate pharmacokinetics and pharmacodynamics analyses will greatly assist our understanding of the likely contribution of novel preparations to the management of anemia.

    The iron content in hair and blood for 37 children athletes who were supplemented with 0, 8 and 16 mg Fe/d, respectively, in the form of ferrous gluconate-containing chocolate for 3 months was determined before and after the supplement by INAA, SRXRF and blood analysis. The experimental results indicated that after the supplement of the iron-fortified food, the ferritin level in blood of the male athletes attained to normal and the iron content in hair was increased with the increasing level of supplement, but not in direct proportion. Most of the female athletes had similar results. It is suggested that supplement of 8 mg Fe/d to a child athlete may be adequate

    A high prevalence of iron deficiency anemia persists in Bedouin Arab and Jewish pediatric populations in southern Israel. To compare the effect of daily use of the micronutrient supplementation (MMS), "Sprinkles," a powdered formulation of iron, vitamins A and C, folic acid and zinc, with liquid iron and vitamins A and D on iron deficiency at 12 months of age. The 621 eligible Bedouin and Jewish infants in the study were assigned to the MMS and control arms and received supplementations from age 6 to 12 months. We examined the change in hemoglobin, hematocrit, mean cell volume, red blood cell distribution, serum ferritin and transferrin saturation. In addition, we used the high Iron Deficiency Index (IDI) if two or more of the above six parameters showed abnormal levels. Rates of anemia decreased significantly over the 6 month period, from 58.8% to 40.6% among Bedouin infants (P = 0.037) and from 40.6 to 15.8% among Jewish infants (P = 0.017). In Bedouin infants the prevalence of high IDI decreased significantly from 79.2% to 67.4% (P = 0.010) in the MMS group, but there was no change in the controls. Among Jewish infants, the high IDI prevalence decreased from 67% to 55.6% with no statistically significant difference in the two study arms. In the multivariate analysis in Bedouin infants MMS use was associated with a reduced risk of 67% in high IDI at age 12 months as compared to controls (P = 0.001). Fewer side effects in the intervention groups in both ethnic populations were reported. MMS fortification of home food can be recommended as an effective and safe method for preventing iron deficiency anemia at 12 months of age.

    Full Text Available Background: Iron supplementation can decrease the absorption of zinc and influence other antioxidants levels such as vitamin C. This study aimed to investigate the effect of iron supplements alone and in combination with vitamin C on zinc and vitamin C status in iron deficient female students. Methods: In a double-blind randomized clinical trail, 60 iron deficient students were selected from 289 volunteers residing in dormitory. After matching, subjects were randomly assigned into two groups: Group I (50 mg elemental iron supplements and Group II (50 mg elemental iron + 500 mg ascorbic acid. Serum ferritin, iron, serum zinc, and plasma vitamin C concentrations were measured by using enzyme-linked immunosorbent assay, spectrophotometer, atomic absorption spectrometer, and colorimeter, respectively after 6 and 12 weeks supplementation. Student′s t-test and repeated measures analysis of variance were applied to analyze the data using SPSS software. Results: Serum zinc levels had no significant differences between 2 groups at the baseline; however, its concentration decreased from 80.9 ± 4.2-68.9 ± 2.7 μg/dl to 81.2 ± 4.5-66.1 ± 2.9 μg/dl (P < 0.001 in Groups I and II, respectively after 6 weeks of supplementation. Continuous supplementation increased serum zinc concentration to baseline levels (79.0 ± 2.9 μg/dl; P < 0.01 in Group I and 70.5 ± 3.1 μg/dl in Group II following 12 weeks of supplementation. Plasma vitamin C increased from 3 ± 0/1-3.3 ± 0.2 mg/dl to 2.7 ± 0. 1-4.2 ± 0.2 mg/dl (P < 0.01 in Groups I and II, respectively. At the end of study, plasma vitamin C significantly increased from 3.3 ± 0.3-4.7 ± 0.3 (P < 0.01 to 4.2 ± 0.2-7.1 ± 0.2 (P < 0.001 in Groups I and II, respectively. Conclusions: Iron supplementation with and without vitamin C led to reduction in serum Zn in iron-deficient female students after 6 weeks. However, the decreasing trend stops after repletion of iron stores and Zn levels returned to the

    Objective Women’s nutritional status during conception and early pregnancy can influence maternal and infant outcomes. This study examined the efficacy of pre-pregnancy supplementation with iron and multivitamins to reduce the prevalence of anemia during the periconceptional period among rural Tanzanian women and adolescent girls. Design A double-blind, randomized controlled trial was conducted in which participants were individually randomized to receive daily oral supplements of folic acid alone, folic acid and iron, or folic acid, iron, and vitamins A, B-complex, C, and E at approximately single recommended dietary allowance (RDA) doses for six months. Setting Rural Rufiji District, Tanzania. Subjects Non-pregnant women and adolescent girls aged 15–29 years (n = 802). Results The study arms were comparable in demographic and socioeconomic characteristics, food security, nutritional status, pregnancy history, and compliance with the regimen (p>0.05). In total, 561 participants (70%) completed the study and were included in the intention-to-treat analysis. Hemoglobin levels were not different across treatments (median: 11.1 g/dL, Q1-Q3: 10.0–12.4 g/dL, p = 0.65). However, compared with the folic acid arm (28%), there was a significant reduction in the risk of hypochromic microcytic anemia in the folic acid and iron arm (17%, RR: 0.61, 95% CI: 0.42–0.90, p = 0.01) and the folic acid, iron, and multivitamin arm (19%, RR: 0.66, 95% CI: 0.45–0.96, p = 0.03). Inverse probability of treatment weighting (IPTW) to adjust for potential selection bias due to loss to follow-up did not materially change these results. The effect of the regimens was not modified by frequency of household meat consumption, baseline underweight status, parity, breastfeeding status, or level of compliance (in all cases, p for interaction>0.2). Conclusions Daily oral supplementation with iron and folic acid among women and adolescents prior to pregnancy reduces risk of anemia. The

    Full Text Available Iron deficiency anaemia is a public health problem that affects all age groups. In Mexico, it is a common cause of morbidity, and accounts for 50% of cases of anaemia worldwide. It is more prevalent during the first 2 years of life, during adolescence and pregnancy. It is characterised by fatigue, weakness, pallor and koilonychia. Treatment is based on dietary recommendations and oral and intravenous iron supplements. In this review article, we summarise the characteristics of iron efficiency anaemia, its metabolism, epidemiology, symptoms and diagnosis, and explore different therapeutic approaches.

    2013-12-01

    Over 250,000 bariatric surgical procedures for the management of morbid obesity are performed in the United States annually. The Roux-en-Y gastric bypass (RYGB) is an effective bariatric procedure because of its efficacy in achieving significant weight loss, low complication rates, and outcomes in reducing cardiovascular and all cause mortality. Because food bypasses the portion of the small intestine whereby micronutrients are normally absorbed, micronutrient deficiencies following surgery may lead to iron deficiency anemia. Iron deficiency anemia is estimated to occur in 6%-50% of post-RYGB patients. Consequently, the procedure requires lifelong behavioral change to ensure therapeutic iron supplementation. A nonsystematic literature search for clinical guidelines, review articles, and research was conducted. Clinical recommendations include prophylactic iron supplementation with ferrous sulfate to prevent iron deficiency anemia. Ferrous sulfate is a well-established cause of constipation possibly resulting in low patient tolerability and subsequent low adherence rates. Strategies for managing the side effects of iron supplementation including constipation may require a unique approach based on the anatomical and functional changes in the post-RYGB patient and the requirement for lifelong iron supplementation. ©2013 The Author(s) ©2013 American Association of Nurse Practitioners.

    The effects of combined chemical application of benomyl, ethylenedianinetetraacetate (EDTA), and iron (Fe) (foliar and root) on lead (Pb) phytoextraction by switchgrass (Panicum virgatum) and corn (Zea mays) was examined. Switchgrass was grown in Pb-contaminated urban topsoil with the following treatments: (C) Control, (B) benomyl, (E) EDTA, (F) foliar-Fe, (BE) benomyl + EDTA, (BF) benomyl + foliar-Fe, (FE) foliar-Fe + EDTA, (BFE) benomyl + foliar-Fe + EDTA. Corn was grown in sand-culture supplemented with Pb (500 mg kg(-1)) with the following treatments: (C) control, (B) benomyl, (E) EDTA, (F) root-Fe, (BE) benomyl + EDTA, (BF) benomyl + root-Fe, (FE) root-iron + EDTA, and, (BFE) benomyl + root-Fe + EDTA. All treatments were replicated three times and pots were arranged in a completely randomized design. Plants were analyzed for element concentration (Fe, Zn, P, and Pb) using either inductively coupled plasma (argon) atomic emission spectroscopy (ICP-AES) or graphite furnace atomic absorption spectrometer. Iron supplementation (foliar and root) affected Pb-translocation in plants. Foliar-Fe treatment increased translocation ratio of Pb (TF-Pb) significantly compared to other treatments with the exception of plants treated with benomyl and BF. Root-Fe treatment in combination with EDTA (FE) increased TF-Pb significantly compared to other treatments. Phytoextraction was improved by the combined chemical application; plants treated with BFE treatment increased Pb-total-phytoextraction by 424% compared to Control plants.

    ABSTRACT: BACKGROUND: In observational studies anaemia and iron deficiency are associated with cognitive deficits, suggesting that iron supplementation may improve cognitive function. However, due to the potential for confounding by socio-economic status in observational studies, this needs to be verified in data from randomised controlled trials (RCTs). AIM: To assess whether iron supplementation improved cognitive domains: concentration, intelligence, memory, psychomotor skills and scholastic achievement. METHODOLOGY: Searches included MEDLINE, EMBASE, PsychINFO, Cochrane CENTRAL and bibliographies (to November 2008). Inclusion, data extraction and validity assessment were duplicated, and the meta-analysis used the standardised mean difference (SMD). Subgrouping, sensitivity analysis, assessment of publication bias and heterogeneity were employed. RESULTS: Fourteen RCTs of children aged 6+, adolescents and women were included; no RCTs in men or older people were found. Iron supplementation improved attention and concentration irrespective of baseline iron status (SMD 0.59, 95% CI 0.29 to 0.90) without heterogeneity. In anaemic groups supplementation improved intelligence quotient (IQ) by 2.5 points (95% CI 1.24 to 3.76), but had no effect on non-anaemic participants, or on memory, psychomotor skills or scholastic achievement. However, the funnel plot suggested modest publication bias. The limited number of included studies were generally small, short and methodologically weak. CONCLUSIONS: There was some evidence that iron supplementation improved attention, concentration and IQ, but this requires confirmation with well-powered, blinded, independently funded RCTs of at least one year\\'s duration in different age groups including children, adolescents, adults and older people, and across all levels of baseline iron status.

    The aim of this study was to assess whether oral liquid levothyroxine would correct tablet levothyroxine malabsorption induced by calcium or iron, two sequestrants of levothyroxine. Nineteen adult hypothyroid patients with tablet levothyroxine malabsorption caused by calcium and/or iron supplements were switched from tablet to liquid levothyroxine at the same dose. Primary outcomes were: (1) significantly lower mean serum thyroid-stimulating hormone with the liquid compared with the tablet formulation, and (2) significantly greater rate of serum thyroid-stimulating hormone less than or equal to 4.12 or 2.5 mU/L.The mean follow-up was 25.2 ± 16.5 weeks. TSH was lower with liquid levothyroxine compared with tablet levothyroxine (7.48 ± 5.8 vs. 1.95 ± 1.3 mU/L, P levothyroxine thyroid-stimulating hormone levels and the first tablet levothyroxine thyroid-stimulating hormone levels or the corresponding rates of thyroid-stimulating hormone levels below the target. Liquid levothyroxine is resistant to the sequestration by calcium or iron. The high rate of thyroid-stimulating hormone normalization already at the first check (6-8 weeks) should avoid frequent adjustments in levothyroxine doses and assays of thyroid-stimulating hormone, with consequent financial savings.

    To study the effect of iron supplementation during pregnancy on epiphyseal growth plate of Sprague dawley rat pups. Study Design: Laboratory based randomized control trial. Place and Duration of Study: This study was conducted at Department of Anatomy, Army Medical College Rawalpindi in collaboration with National Institute of Health (NIH) Islamabad, from Mar 2016 to Nov 2016. Material and Methods: Eight female and two male Sprague Dawley rats, 3-4 months old were selected and divided into two groups and kept for breeding. Pregnant rats were divided into two groups. Four pregnant rats in each group. Group A1was control group and group B1 was experimental group. Iron supplementation was given once daily throughout pregnancy till the time of delivery. Iron was given to the experimental group in syrup form (Sytron syrup containing iron as sodium feredetate). Each 5ml of sytron syrup contains 27.5mg of elemental iron content1. The dose was mixed in water given to the animal. Maternal body weight (wt.) was recorded at the start and the end of experiment. As the rat pups were born, they were weighed and euthanized. Right femur of each rat pup was removed for the epiphyseal plate analysis. It was processed, embedded and stained with Hematoxylin and Eosin, Perl's stain for histological study. Hypertrophy and proliferative zone length were histologically and statistically analyzed. Results: Height of hypertrophy and proliferative zone was measured. Mean values of the heights of two zones were taken. Heights of hypertrophy and proliferative zones were considerably decreased in group B1 as compared to groups A1. Conclusion: Indiscriminate iron supplementation to the rats throughout pregnancy without checking serum iron levels can disturb the longitudinal growth of epiphyseal plate of femur. The height of the hypertrophy zone and proliferative zone was significantly reduced in iron supplementation group as compared to the control group. (author)

    Two experiments were conducted to evaluate the effects of vitamin C supplementation on performance, iron status and immune function of pigs during the 21-day post-weaning period. In experiment one, 48 crossbred pigs (Chester White x Large White x Yorkshire), weaned at 30 days of age and weighing 7.7 +/- 0.9 kg, were allotted to diets containing either 0 or 300 mg/kg vitamin C. In experiment two, 96 crossbred pigs (Chester White x Large White x Yorkshire), weaned at 20 +/- 2 days and weighing 7.1 +/- 0.5 kg, were allotted to diets containing 0.75 or 300 mg/kg vitamin C. Six replicate pens were assigned to each treatment in experiment one while experiment two had eight replicates. All pens housed two barrows and two gilts. In both experiments, no improvement (P > 0.05) in growth rate, feed intake or feed conversion was observed as a result of vitamin C supplementation. Plasma iron concentration increased (P immunity (P > 0.05). In trial 2, the plasma levels of the immunoglobulin IgG showed a linear (P = 0.07) increase with increasing levels of vitamin C and the same trend was noted in trial 1. Antibody titers to bovine serum albumin also tended to increase in both trials but the increases were not statistically significant. In conclusion, the overall results of these experiments indicate that weanling pig performance is not improved as a result of vitamin C supplementation. Whether or not vitamin C plays a role in stimulating humoral immune function in pigs requires further study since the results of our experiments do not completely rule out the possibility that such a role exists.

    Children are known to be venerable to lead (Pb) toxicity. The blood-brain barrier (BBB) in immature brain is particularly vulnerable to Pb insults. This study was designed to test the hypothesis that Pb exposure damaged the integrity of the BBB in young animals and iron (Fe) supplement may prevent against Pb-induced BBB disruption. Male weanling Sprague-Dawley rats were divided into four groups. Three groups of rats were exposed to Pb in drinking water containing 342 μg Pb/mL as Pb acetate, among which two groups were concurrently administered by oral gavage once every other day with 7 mg Fe/kg and 14 mg Fe/kg as FeSO 4 solution as the low and high Fe treatment group, respectively, for 6 weeks. The control group received sodium acetate in drinking water. Pb exposure significantly increased Pb concentrations in blood by 6.6-folds (p < 0.05) and brain tissues by 1.5-2.0-folds (p < 0.05) as compared to controls. Under the electron microscope, Pb exposure in young animals caused an extensive extravascular staining of lanthanum nitrate in brain parenchyma, suggesting a leakage of cerebral vasculature. Western blot showed that Pb treatment led to 29-68% reduction (p < 0.05) in the expression of occludin as compared to the controls. Fe supplement among Pb-exposed rats maintained the normal ultra-structure of the BBB and restored the expression of occludin to normal levels. Moreover, the low dose Fe supplement significantly reduced Pb levels in blood and brain tissues. These data suggest that Pb exposure disrupts the structure of the BBB in young animals. The increased BBB permeability may facilitate the accumulation of Pb. Fe supplement appears to protect the integrity of the BBB against Pb insults, a beneficial effect that may have significant clinical implications

    Previous short-term supplementation studies showed no additional hematologic benefit of multiple micronutrients (MMN) compared with iron + folic acid (IFA) in adolescent girls. This study examines whether long-term once- or twice-weekly supplementation of MMN can improve hemoglobin (Hb) and micronutrient status more than twice-weekly IFA supplementation in anemic adolescent girls in Bangladesh. Anemic girls (n = 324) aged 11-17 y attending rural schools were given once- or twice-weekly MMN or twice-weekly IFA, containing 60 mg iron/dose in both supplements, for 52 wk in a randomized double-blind trial. Blood samples were collected at baseline and 26 and 52 wk. Intent to treat analysis showed no significant difference in the Hb concentration between treatments at either 26 or 52 wk. However, after excluding girls with hemoglobinopathy and adjustment for baseline Hb, a greater increase in Hb was observed with twice-weekly MMN at 26 wk (P = 0.045). Although all 3 treatments effectively reduced iron deficiency, once-weekly MMN produced significantly lower serum ferritin concentrations than the other treatments at both 26 and 52 wk. Both once- and twice-weekly MMN significantly improved riboflavin, vitamin A, and vitamin C status compared with IFA. Overall, once-weekly MMN was less efficacious than twice-weekly MMN in improving iron, riboflavin, RBC folic acid, and vitamin A levels. Micronutrient supplementation beyond 26 wk was likely important in sustaining improved micronutrient status. These findings highlight the potential usefulness of MMN intervention in this population and have implications for programming.

    Full Text Available Ferric carboxymaltose (FCM is an intravenous iron formulation to correct iron deficiency. Although its use has been extensively studied in clinical trials, real-world evidence regarding FCM treatment is scarce. Our aim was to evaluate the efficacy and tolerability of FCM treatment in patients with iron deficiency, with or without anemia, at a hospital outpatient clinic. Data was collected retrospectively from medical records. During this 2-year study, 459 patients were included. Mean age was 58.6 ± 17.5 years and most patients received cumulative FCM doses of 501–1000 mg (63.2%. Six weeks after administration of FCM, efficacy endpoints hemoglobin increase ≥2 g/dL, hemoglobin increase ≥3 g/dL, and transferrin saturation > 20% were attained by 41%, 20%, and 63% of patients, respectively. Patients who received higher FCM doses showed significant reduced odds of not achieving hemoglobin increase ≥2 g/dL (501–1000 mg, adjusted odds ratio [OR]: 0.34, 95% confidence interval [CI] 0.18–0.62; 1001–3000 mg, OR: 0.19, 95% CI 0.07–0.49, compared to 500 mg doses. Treatment-emergent adverse events were documented in <4% of patients. In conclusion, FCM treatment was effective and well-tolerated by outpatients with iron deficiency at a hospital clinic, and its dosage should be adjusted to improve iron deficiency management in clinical practice.

To determine the degree of liking of the Oportunidades programme dietary supplements (DS –purees and beverages– added with different iron salts (IS: reduced iron (RI, ferrous sulphate (FS or ferrous fumarate (FF during 24 weeks of storage. Materials and methods. The DS were evaluated through a hedonic scale for aroma, flavour and colour attributes; at time zero and every eight weeks, each panel member evaluated three DS with same flavour and presentation but different IS. Seventy women participated as panel members. Results. The chocolate and banana DS exhibited a change in preference by colour and flavour due to storage. DS with FS or RI showed the least preference by flavour and colour in the context of the three IS considered. The chocolate and neutral DS enriched with FS changed their colour and flavour. Conclusion. DS were, in general, well-liked; nonetheless, for purees enriched with FS and for beverages enriched with RI, the less-liked attributes were colour and flavour

    As part of the efforts to reduce iron deficiency anemia (IDA), the Mexican Federal program PROGRESA distributes complementary foods to toddlers and pregnant women living in extreme poverty. Complementary foods were originally fortified with hydrogen-reduced iron, which proved a limited efficacy. The supplement was reformulated to provide higher iron bioavailability. This investigation aims to assess the sensory changes and the acceptance of new versions of the complementary foods fortified with either reduced iron, ferrous fumarate, or ferrous sulfate, stored at room temperature for 2, 4, and 6 mo. Complementary foods were presented without flavor (plain) or flavored with either chocolate or vanilla. The complementary foods were evaluated in toddlers and their mothers using a hedonic scale. The percentage of overall acceptance for the baby foods was higher in toddlers (80% to 88%) than in their mothers (63% to 68%). The complementary foods with a better acceptance were those fortified with reduced iron (63% to 68%) and ferrous fumarate (61% to 80%) independently of the flavoring added. The acceptance of the beverage intended for women was better for those fortified with reduced iron (52% to 63%) or ferrous fumarate (44% to 63%) in their vanilla-flavored version. For women, the most accepted sources of iron were reduced iron (50% to 60%) and ferrous fumarate (50% to 58%).

    We investigated the effect of iron deficiency anemia (IDA) on levels of glycated hemoglobin (HbA1c) and to compare its levels before and after iron supplementations. Age and sex matched subjects were enrolled and clustered in 2 groups: IDA (n=62) and healthy controls (HC; n=60). HbA1c levels were estimated by HPLC. Hemogram were estimated by hematology analyser. Serum ferritin (ELISA) and other parameters of iron profile were measured by standard guidelines of ICSH. HbA1c values and iron studies were repeated after 3months of iron supplementation to determine the effect of iron therapy on HbA1c levels. Significantly higher HbA1c levels were observed in IDA subjects compared to HC (5.51±0.696 v/s 4.85±0.461%, p<0.001). A significant negative correlation was observed between HbA1c and hemoglobin, hematocrit, RBC count, MCH, MCHC and serum ferritin in IDA subjects (r=-0.632, -0.652, -0.384, -0.236, -0.192 and -0.441). Significant decline was noticed in HbA1c levels in IDA subjects after iron supplementation (5.51±0.696 before treatment v/s 5.044±0.603 post-treatment; p<0.001). Post treatment, 70% subjects (14/20) with HbA1c in pre-diabetes range normalised to normal glucose tolerance (NGT) range and out of 6 patients with pre-treatment HbA1c in diabetes range, 5 reverted to pre-diabetes range while 1 of them reverted to the NGT range. Caution must be exercised in interpreting the results of HbA1c in patients of IDA and iron deficiency must be corrected before diagnosing diabetes and pre-diabetes solely on the basis of HbA1c criteria.

    Full Text Available BACKGROUND Anaemia is perceived to be a major public health problem especially among adolescent females .Findings from National Family Health Survey NFHS (2005-06 indicate that 56% of the adolescent girls in India are anaemic and, of these 17% suffer from moderate to severe anaemia. The prevalence of anaemia in female adolescent age group is still an understudied subject. The aims of this study were to evaluate the recently initiated WIFS program for government school girls with respect to implementation and impact on trends in prevalence of Anaemia among adolescent girls in a Bengaluru rural school. MATERIALS AND METHODS Cross-sectional, descriptive exploratory research study was used. The choice of the school was based on commitment to administration of weekly iron-folic acid supplements (WIFS programme. All the girl students from class 6 th to 10th of Government High and Senior Secondary school (age group, 11-19 years who were a part of WIFS were enrolled as study participants. Qualitative data on anaemia awareness and diet history, compliance, side effects were taken from these girls. General information on age, height, weight were collected and BMI calculated. Hb estimation was done by Haemocue method. Statistical Analysis- Analysis were prepared by IBM SPSS Statistics version 22. RESULTS Out of the 95girls in the school, there were 81 girls (85.26% reported to consume one tablet of Iron folic acid (IFA weekly in the past 1 year, with no major side effects. The girls had knowledge about symptoms of anaemia and iron-rich diet. Hb estimates indicated 79.01% non anaemic, prevalence of anaemia was 20.99%; none of the girls had severe anaemia, 1.2% had moderate anaemia and the remaining 19.8% belonged to mild anaemia category, indicating a significant decline. The mean BMI of the study sample was 17.53 kg/m2 with 67.9% underweight and 6.2% overweight. CONCLUSION Overall, in this school, the WIFS program was found to be well implemented with good

    Pregnant women have an increased need for iron that might not be met with diet alone. Due to physiologic anemia and population differences, no set criteria for defining iron deficiency anemia (IDA) are available globally. Serum ferritin and transferrin levels are often used to guide therapy by clinicians. Studies have reported an association between poor iron status and negative health outcomes such as low birth weight, premature birth, and perinatal death for women and their infants, although the evidence is weak.

    Full Text Available Cadmium signifies a severe threat to crop productivity and green gram is a notably iron sensitive plant which shows considerable variation towards cadmium stress. A gel-based proteomics analysis was performed with the roots of green gram exposed to iron and cadmium combined treatments. The resulting data show that twenty three proteins were down-regulated in iron-deprived roots either in the absence (−Fe/−Cd or presence (−Fe/+Cd of cadmium. These down-regulated proteins were however well expressed in roots under iron sufficient conditions, even in the presence of cadmium (+Fe/+Cd. The functional classification of these proteins determined that 21% of the proteins are associated with nutrient metabolism. The other proteins in higher quantities are involved in either transcription or translation regulation, and the rest are involved in biosynthesis metabolism, antioxidant pathways, molecular chaperones and stress response. On the other hand, several protein spots were also absent in roots in response to iron deprivation either in absence (−Fe/−Cd or presence (−Fe/+Cd of cadmium but were well expressed in the presence of iron (+Fe/+Cd. Results suggest that green gram plants exposed to cadmium stress are able to change the nutrient metabolic balance in roots, but in the mean time regulate cadmium toxicity through iron supplements.

    Iron deficiency, associated with a decline in cognitive function, is the most common nutritional deficiency globally. The present study aimed to identify the impact of weekly iron supplements on the attention function of female students from a high school in North Khorasan Province, Iran. This was a blind, controlled, clinical trial study, involving 200 female students who were chosen using the stratified randomised sampling method. First, laboratory studies were performed to detect iron consumption limitations. Next, the 200 students were divided randomly and equally into case and control groups. The case group was treated with 50 mg of ferrous sulfate twice a week for 16 weeks. We compared both groups' data on attention, iron status and erythrocyte indices. Questionnaires were used to collect demographic data, while clinical data was collected using complete blood count and Toulouse-Piéron tests. Data was analysed using descriptive statistics, as well as paired and independent t-tests. The mean attention scores of the case and control groups were 104.8 ± 7.0 and 52.7 ± 9.6, respectively (p attention scores and haemoglobin concentrations of the case group were found to be improved by approximately 90% and 10%, respectively. Oral iron supplements (50 mg twice a week for 16 weeks) were able to improve the attention span and haematologic indices of female high school students.

    This study evaluated the effects of the interaction of diabetes and a carbonyl iron supplemented on hepatic and pancreatic tissues, oxidative stress markers and liver peroxisome proliferator-activated receptor-α expressions. Hamsters were divided: Control which received a standard AIN 93 diet; Control Iron, composed of control animals that received a diet with 0.83% carbonyl iron; Diabetic, composed of animals that received a injection of streptozotocin (50 mg/kg, intraperitoneal) on day 35; and Diabetic Iron composed of streptozotocin treated animals that received a diet supplemented with carbonyl iron. Diabetes increased the glucose level and reduced triglycerides. Diabetic Iron group showed higher levels of glucose and serum triglycerides as compared to the Diabetic group. Diabetes decreased mRNA levels of peroxisome proliferator-activated receptor-α. Iron attenuated the diabetes induced down regulation of peroxisome proliferator-activated receptor-α mRNA. Moreover, diabetes increased carbonyl protein and decreased glutathione levels and catalase activity, while iron attenuated the increase in levels of carbonyl protein and attenuated the decrease in those of glutathione level and catalase activity. Histological analysis shows that supplementation iron caused an increase in the size of the islets in Control Iron. The results show that iron does not aggravated liver oxidant/antioxidant status and peroxisome proliferator-activated receptor-α expression in diabetic hamsters. PMID:21980225

    Full Text Available OBJECTIVE: To analyze adherence to the recommended iron, zinc and multivitamin supplementation guidelines for preemies, the factors associated with this adherence, and the influence of adherence on the occurrence of anemia and iron, zinc and vitamin A deficiencies. METHODS: This prospective cohort study followed 58 preemies born in 2014 until they reached six months corrected age. The preemies were followed at a referral secondary health service and represented 63.7% of the preterm infants born that year. Outcomes of interest included high or low adherence to iron, zinc and multivitamin supplementation guidelines; prevalence of anemia; and prevalences of iron, zinc, and vitamin A deficiencies. The prevalence ratios were calculated by Poisson regression. RESULTS: Thirty-eight (65.5% preemies presented high adherence to micronutrient supplementation guidelines. At six months of corrected age, no preemie had vitamin A deficiency. The prevalences of anemia, iron deficiency and zinc deficiency were higher in the low-adherence group but also concerning in the high-adherence group. Preemies with low adherence to micronutrient supplementation guidelines were 2.5 times more likely to develop anemia and 3.1 times more likely to develop zinc deficiency. Low maternal education level increased the likelihood of nonadherence to all three supplements by 2.2 times. CONCLUSIONS: Low maternal education level was independently associated with low adherence to iron, zinc and vitamin A supplementation guidelines in preemies, which impacted the prevalences of anemia and iron and zinc deficiencies at six months of corrected age.

    Iron deficiency anemia, zinc and vitamin A deficiencies are serious public health problems in Cameroon, as in many developing countries. Local vegetables which are sources of provitamin A carotenoids (PACs) can be used to improve vitamin A intakes. However, traditional meals are often unable to cover zinc and iron needs. The aim of this study was to determine the bioavailability of 3 PACs (α-carotene, β-carotene, and β-cryptoxanthin) in young men, who were fed with a vitamin A-free diet and received iron and zinc supplementation. Twelve healthy participants were divided into three groups and were supplemented with elemental iron (20 mg of iron fumarate), 20 mg of zinc sulfate or iron+zinc (20 mg of iron in the morning and 20 mg of zinc in the evening) for 11 d. They were given a vitamin A- and PAC-free diet from the 6th to the 11th day, followed by a test meal containing 0.55 kg of freshly peeled papaya as a source of PACs. Blood samples were collected four times successively on the 11th day (the test meal day), at T0 (just after the test meal), after 2 h (T2), after 4 h (T4) and after 7 h (T7). Ultracentrifugation was used to isolate serum chylomicrons. Retinol appearance and PAC postprandial concentrations were determined. The supplementation with zinc, iron and iron+zinc influenced the chylomicron appearance of retinol and PACs differently as reflected by retention times and maximum absorption peaks. Iron led to highest retinol levels in the chylomicron. Zinc and iron+zinc supplements were best for optimal intact appearance of α-carotene, β-carotene and β-cryptoxanthin respectively. Supplementation with iron led to the greatest bioavailability of PACs from papaya and its conversion to retinol.

    Full Text Available The chemiluminescence (CL signal immediately appeared when a hydrogen peroxide solution was injected into an iron-phthalocyanine tetrasulfonic acid (Fe-PTS aqueous solution. Moreover, the CL intensity of Fe-PTS decreased by adding L-tyrosine. Based on these results, the determination of trace amounts of L-tyrosine was developed using the quenching-chemiluminescence. The calibration curve of L-tyrosine was obtained in the concentration range of 2.0×10−7 M to 2.0×10−5 M. Moreover, the relative standard deviation (RSD was 1.63 % (=5 for 2.0×10−6 M L-tyrosine, and its detection limits (3σ were 1.81×10−7 M. The spike and recovery experiments for L-tyrosine were performed using a soft drink. Furthermore, the determination of L-tyrosine was applied to supplements containing various kinds of amino acids. Each satisfactory relative recovery was obtained at 98 to 102%.

    Iron has been suggested to reduce the erosive potential of cola drinks in vitro. The aim of this study was to evaluate in situ the effect of ferrous sulfate supplementation on the inhibition of the erosion caused by a cola drink. Ten adult volunteers participated in a crossover protocol conducted in two phases of 5 days, separated by a washout period of 7 days. In each phase, they wore palatal devices containing two human enamel and two human dentin blocks. The volunteers immersed the devices for 5 min in 150 mL of cola drink (Coca-ColaTM, pH 2.6), containing ferrous sulfate (10 mmol/L) or not (control), 4 times per day. The effect of ferrous sulfate on the inhibition of erosion was evaluated by profilometry (wear). Data were analyzed by paired t tests (pcola drinks with ferrous sulfate can be a good alternative for the reduction of their erosive potential. Additional studies should be done to test if lower ferrous sulfate concentrations can also have a protective effect as well as the combination of ferrous sulfate with other ions.

    Full Text Available Abstract Background Dietary creatine has been largely used as an ergogenic aid to improve strength and athletic performance, especially in short-term and high energy-demanding anaerobic exercise. Recent findings have also suggested a possible antioxidant role for creatine in muscle tissues during exercise. Here we evaluate the effects of a 1-week regimen of 20 g/day creatine supplementation on the plasma antioxidant capacity, free and heme iron content, and uric acid and lipid peroxidation levels of young subjects (23.1 ± 5.8 years old immediately before and 5 and 60 min after the exhaustive Wingate test. Results Maximum anaerobic power was improved by acute creatine supplementation (10.5 %, but it was accompanied by a 2.4-fold increase in pro-oxidant free iron ions in the plasma. However, potential iron-driven oxidative insult was adequately counterbalanced by proportional increases in antioxidant ferric-reducing activity in plasma (FRAP, leading to unaltered lipid peroxidation levels. Interestingly, the FRAP index, found to be highly dependent on uric acid levels in the placebo group, also had an additional contribution from other circulating metabolites in creatine-fed subjects. Conclusions Our data suggest that acute creatine supplementation improved the anaerobic performance of athletes and limited short-term oxidative insults, since creatine-induced iron overload was efficiently circumvented by acquired FRAP capacity attributed to: overproduction of uric acid in energy-depleted muscles (as an end-product of purine metabolism and a powerful iron chelating agent and inherent antioxidant activity of creatine.

    There are no previous studies evaluating the effect of intravenous iron therapy on functional and cognitive status of patients with hip fracture (HF). A single-centre randomised, placebo-controlled, double-blind and parallel treatment, clinical trial has been designed to assess the efficacy of intravenous iron therapy during the peri-operative period in elderly patients suffering from a HF. Blinding will be ensured by the packaging of the drug infusion system. On days 1, 3, and 5 from admission, the intervention group will receive 200mg Venofer® (iron sucrose) diluted in 100ml saline, and the control group 100ml saline, also on days 1, 3 and 5. Patients will received conventional treatment in ortho-geriatric unit of the Hospital Infanta Sofia. Functional variables (activities of daily living and walking), cognitive (cognitive status and delirium), surgical, demographic and clinical characteristics will be collected during admission in order to assess the impact of treatment. A safety analysis of the treatment will also performed. Patients will be followed-up at 3, 6, and 12 months. The study will attempt to provide evidence on the impact of the intravenous iron administration on functional recovery. It will be determined whether iron therapy negatively affects the incidence of post-operative delirium. Finally, report will be presented on the safety data of intravenous iron in elderly HF patients, as well as the impact on allogenic blood transfusion savings. The inclusion of elderly HF patients admitted to an ortho-geriatric unit, in a clinical trial, will help to improve the knowledge of the treatment impact on a usual scenario, and provide useful data for use in other units.

    2005-12-01

    Lack of effective implementation mechanisms is identified as a major obstacle in the prevention and control of iron-deficiency anemia. This paper discusses experiences gained from implementing iron-folic acid supplementation in the Philippines, Vietnam, and Cambodia. The understanding of contextual elements is proposed as a foundation for planning interventions. Moreover, it is suggested that a social marketing framework should provide a way of thinking about how to influence related behaviors. The application of a social marketing framework applied using a "5 P's" approach: public relations and collaboration, product, price, place, and promotion, is described, as well as enabling factors (possibilities) and inhibiting factors (challenges) of this approach. Although a program to improve iron nutrition among women of reproductive age may not be simple to implement, it is essential to enhancing health, human development, and economic advancement in developing countries.

    Globally, anemia is a public health problem affecting the life of more than two billion people. Pregnant women are at high risk of iron deficiency anemia due to increased nutrient requirement during pregnancy. Iron-folic acid supplementation is the main strategy for prevention and control of iron deficiency anemia and its effectiveness depends on adherence to Iron-Folic Acid tablets. In the refugee camps of Ethiopia, despite the efforts made to reduce iron deficiency anemia during pregnancy, information about adherence to iron-folic acid supplementation and its associated factors are lacking. The objective of this study was to assess magnitude and factors associated with adherence to iron-folic acid supplementation, among pregnant women, in Shire refugee camps. Institution based cross-sectional study with mixed design (quantitative and qualitative) was carried out among pregnant women in Shire refugee camps from September to November 2015. For quantitative data, a sample of 320 pregnant women was systematically selected and data were collected via interview administered structured questionnaire. Quantitative data were coded and entered into Epi-info version 3.5.1 and exported into a statistical package for social sciences (SPSS) Version 19.0 software for analysis. Bivariable and multivariable logistic regressions were employed to identify the predictors at p-value knowledge about anemia [AOR; 0.23 95% CI (0.14, 0.38)] and not receiving information about importance of iron-folic acid supplementation [AOR; 0.43 95% CI (0.25, 0.74)] were negatively associated with adherence to iron and folic acid., Having four or more antenatal care visits [AOR; 2.83 95% CI (1.46, 5.48)] were positively significantly associated with adherence to iron-folic acid supplementation. Adherence rate of iron-folic acid supplementation during pregnancy in the study area is relatively low.

    Full Text Available CONTEXT AND OBJECTIVE: Low compliance among mothers regarding the treatment of anemic children using daily doses of ferrous sulfate administered at home has been reported. This study aimed to establish the effectiveness of weekly doses administered by mothers at home compared with weekly supplements administered directly by healthcare professionals, to reduce the prevalence of anemia. DESIGN AND SETTING: This was a randomized clinical trial at a public healthcare clinic in São José do Rio Preto, Brazil. METHODS: This iron supplementation study was carried out using two intervention groups. The sample population was 130 infants, randomly allocated to two groups of 65 children. All of them received 12 weekly doses of 25 mg of elemental iron, administered either in the public healthcare clinic or at their homes. RESULTS: Treatment compliance was shown in both groups. The prevalence of anemia among all of the children was 75% at the beginning of supplementation and 46.3% at the end of the period (P < 0.0005, corresponding to a reduction in the number of anemic children of 38.3%. The average increases in hemoglobin concentration levels were 0.75 g/dl and 0.65 g/dl, respectively for home interventions and healthcare clinic administration (P < 0.00005. CONCLUSION: Weekly supplementation of 25 mg of iron was proven to be efficient in reducing anemia, using interventions both at home and in healthcare clinics. Compliance among the mothers was achieved because weekly supplementation was easy to administer and had few side effects. The results showed that the treatment presented low cost and fast benefits.

    The primary aim of this study was to examine the effects of 11 weeks of iron supplementation on hematological and strength markers in elite female volleyball players. Twenty-two volleyball players (aged 27.0 ± 5.6 years) from 2 Spanish First National League teams participated and were counterbalanced into 1 of 2 groups based upon iron status: (i) control group (CG, n = 11); or (ii) iron treatment group (ITG, n = 11), which received 325 mg/day of ferrous sulphate daily. Subjects performed their team's regimen of training or match play every day. Both groups were tested for hematological and strength levels at 2 points: (i) baseline (T0, before preseason) and (ii) 11 weeks later (T11, post-testing). Hematological parameters were serum iron (sFe), serum ferritin (FER), transferrin saturation index (TSI), and hemoglobin (Hb); strength assessments were bench press, military press, half-squat, power clean, clean and jerk, and pull-over. CG experienced a significant decrease (p 0.05). Consequently, in ITG all hematological parameters were significantly greater (p volleyball players during the competitive season.

    Full Text Available Female workers of childbearing age (WUS as a major of human resources in many agribusiness exposed to anemia. This study aims to improve the iron status of anemic WUS workers with low hemoglobin (Hb levels, who work in a pineapple agribusiness by iron supplementation. This study was conducted two periods, using a double-blind randomized trial design. Subjects were divided into two treatment groups supplements, namely IF that was given iron + folic acid and MVM that was given multi vitamin and mineral containing 15 different vitamins and minerals including iron and folic acid. The subjects of period-1 were 25 married WUS (IF=13, MVM=12 and of period-2 were 15 single WUS (BF=7, MVM=8. Supplementation performed three times weekly for 10 weeks. After supplementation, the levels of Hb, haematocrit (Hc and serum ferritin of BF-group increased, whereas there were declines in MVM-group. The increase in Hb and Hc in married WUS was higher than the single. However, their Hb was fallen down when supplementation was continued without supervision and getting down when not given the supplements anymore. Supplementation with iron is a must for WUS workers, because they are not able to increase their Hb if only rely on their food.

    Provision of routine iron supplements to prevent anaemia could increase the risk for lower genital tract infections as virulence of some pathogens depends on iron availability. This trial in Burkina Faso assessed whether weekly periconceptional iron supplementation increased the risk of lower genital tract infection in young non-pregnant and pregnant women. Genital tract infections were assessed within a double blind, controlled, non-inferiority trial of malaria risk among nulliparous women, randomised to receive either iron and folic acid or folic acid alone, weekly, under direct observation for 18 months. Women conceiving during this period entered the pregnancy cohort. End assessment (FIN) for women remaining non-pregnant was at 18 months. For the pregnancy cohort, end assessment was at the first scheduled antenatal visit (ANC1). Infection markers included Nugent scores for abnormal flora and bacterial vaginosis (BV), T. vaginalis PCR, vaginal microbiota, reported signs and symptoms, and antibiotic and anti-fungal prescriptions. Iron biomarkers were assessed at baseline, FIN and ANC1. Analysis compared outcomes by intention to treat and in iron replete/deficient categories. A total of 1954 women (mean 16.8 years) were followed and 478 (24.5%) became pregnant. Median supplement adherence was 79% (IQR 59-90%). Baseline BV prevalence was 12.3%. At FIN and ANC1 prevalence was 12.8% and 7.0%, respectively (P Iron-supplemented non-pregnant women received more antibiotic treatments for non-genital infections (P = 0.014; mainly gastrointestinal infections (P = 0.005), anti-fungal treatments for genital infections (P = 0.014) and analgesics (P = 0.008). Weekly iron did not significantly reduce iron deficiency prevalence. At baseline, iron-deficient women were more likely to have normal vaginal flora (P = 0.016). Periconceptional weekly iron supplementation of young women did not increase the risk of lower genital tract infections but did increase

    Restless legs syndrome (RLS) and periodic limb movement disorder (PLMD) are thought to center around a genetically mediated sensitivity to iron insufficiency. Previous studies have shown the effectiveness of short-term iron therapy in children with low iron storage. Little is known, however, about long-term iron treatment in children with RLS and PLMD. Therefore, we performed this study to assess the long-term effect of iron therapy in children with RLS and PLMD. A retrospective chart review was performed for children who met the following criteria: A) diagnosed as having either RLS or PLMD, B) started on iron supplementation, C) followed up for >2 years in a sleep clinic. Baseline values for iron, ferritin, and periodic limb movement of sleep index (PLMS index) were defined in the three months leading up to the initiation of iron therapy. Values were also computed for follow-up periods of 3-6 months, 1-2 years, and >2 years. Serum iron and ferritin levels and PLMS index were compared between baseline and all subsequent follow-ups. In total, 105 patients met inclusion criteria, of whom 64 were diagnosed with PLMD alone, seven with RLS alone, and 35 with both RLS and PLMD. The average age was 10.2 ± 5.3 years. Compared to the baseline (27.4 ± 12.1 ng/ml), the average ferritin values at 3-6 months (45.62 ± 21.2 ng/ml, p 2 years (54.7 ± 40.5 ng/ml, p 2 years (10 ± 14.5/h, p 2 years after iron therapy initiation in our RLS/PLMD cohort with a long-term follow-up.

    Preoperative anemia is a common and potentially serious hematological problem in elective surgery and increases the risk for perioperative red blood cell (RBC) transfusion. Transfusion is associated with postoperative morbidity and mortality. Preoperative intravenous (IV) iron therapy has been proposed as an intervention to reduce perioperative transfusion; however, studies are generally small, limited, and inconclusive. We propose performing a systematic review and meta-analysis. We will search MEDLINE, EMBASE, EBM Reviews, Cochrane-controlled trial registry, Scopus, registries of health technology assessment and clinical trials, Web of Science, ProQuest Dissertations and Theses, and conference proceedings in transfusion, hematology, and surgery. We will contact our study drug manufacturer for unpublished trials. Titles and abstracts will be identified and assessed by two reviewers for potential relevance. Eligible studies are: randomized or quasi-randomized clinical trials comparing preoperative administration of IV iron with placebo or standard of care to reduce perioperative blood transfusion in anemic patients undergoing major surgery. Screening, data extraction, and quality appraisal will be conducted independently by two authors. Data will be presented in evidence tables and in meta-analytic forest plots. Primary efficacy outcomes are change in hemoglobin concentration and proportion of patients requiring RBC transfusion. Secondary outcomes include number of units of blood or blood products transfused perioperatively, transfusion-related acute lung injury, neurologic complications, adverse events, postoperative infections, cardiopulmonary complications, intensive care unit (ICU) admission/readmission, length of hospital stay, acute kidney injury, and mortality. Dichotomous outcomes will be reported as pooled relative risks and 95% confidence intervals. Continuous outcomes will be reported using calculated weighted mean differences. Meta-regression will be

    Full Text Available Iron or zinc deficiency is one of the most important nutritional disorders which causes health problem. However, food fortification with minerals often induces unacceptable organoleptic changes during preparation process and storage, has low bioavailability and solubility, and is expensive. Nanotechnology surface modification to obtain novel characteristics can be a useful tool to overcome these problems. In this study, the efficacy and potential toxicity of dispersible Fe or Zn supplement coated in dextrin and glycerides (SunActive FeTM and SunActive ZnTM were evaluated in terms of cytotoxicity, intestinal transport, and bioavailability, as compared with each counterpart without coating, ferric pyrophosphate (FePP and zinc oxide (ZnO nanoparticles (NPs, respectively. The results demonstrate that the cytotoxicity of FePP was not significantly affected by surface modification (SunActive FeTM, while SunActive ZnTM was more cytotoxic than ZnO-NPs. Cellular uptake and intestinal transport efficiency of SunActive FeTM were significantly higher than those of its counterpart material, which was in good agreement with enhanced oral absorption efficacy after a single-dose oral administration to rats. These results seem to be related to dissolution, particle dispersibility, and coating stability of materials depending on suspending media. Both SunActiveTM products and their counterpart materials were determined to be primarily transported by microfold (M cells through the intestinal epithelium. It was, therefore, concluded that surface modification of food fortification will be a useful strategy to enhance oral absorption efficiency at safe levels.

    Full Text Available Little evidence about the effects of antenatal iron supplementation on infant anaemia is available. The aim was to compare effects on six-month-old infants' Haemoglobin (Hb concentration and anaemia of daily iron-folic acid (IFA, twice-weekly IFA with or without other micronutrients (MMN and usual antenatal care in rural Vietnam.Secondary data analysis from: a prospective population-based observational study (OS which examined effects of antenatal psychosocial factors, anaemia and iron deficiency on infant development and health; and a three-arm cluster randomised trial (CRT of different antenatal iron supplementation regimens. In the OS 497 women (<20 weeks gestation from 50 randomly-selected communes participated, and in the CRT 1,258 pregnant women (<16 weeks gestation in 104 communes were allocated randomly to trial arms. The main outcome was six-month-old infant Hb concentration. Baseline data included women's socio-demographic characteristics, reproductive health, Hb and serum ferritin. Mean differences in infant Hb and odds ratios of infant anaemia between CRT arms and OS were calculated by multivariable regression models, controlling for baseline differences and clustering, using robust standard errors. Infant anaemia prevalence was 68.6% in the OS, 47.2% daily IFA, 53.5% weekly IFA, and 50.3% MMN conditions. After adjustment, mean infant haemoglobin levels in daily IFA (mean difference = 0.95 g/dL; 95%CI 0.7-11.18; weekly IFA (0.91; 95%CI 0.69-1.12 and MMN (1.04; 95%CI 0.8-1.27 were higher than in the OS. After adjustment there were lower odds ratios of anaemia among infants in the daily IFA (OR = 0.31; 95% CI 0.22-0.43, weekly IFA (0.38; 95%CI 0.26-0.54 and MMN (0.33; 95%CI 0.23-0.48 groups than in the OS.Infant anaemia is a public health problem in Vietnam and other resource-constrained countries. All supplementation regimens could have clinically significant benefits for Hb and reduce anaemia risk among six-month-old infants

    Anaemia due to iron deficiency is recognized as one of the major nutritional deficiencies in women and children in developing countries. Daily iron supplementation for pregnant women is recommended in many countries. The aim of the study was to investigate the factors that contribute to compliance to the consumption of iron and folate supplements by pregnant woman in Mafikeng local municipality, North West Province, South Africa. A mixed method of descriptive, exploratory and cross-sectional design was used. Ten clinics were used as a sample frame where 57 pregnant women and 10 health workers were purposefully and conveniently selected. Quantitative techniques were used to collect data on attendance, consumption and nutrition knowledge using the self-reported questionnaire by pregnant women, and structured interview for health workers. Qualitative design was used to conduct in - depth focus-group discussions to gather information on compliance to the consumption of supplements by pregnant women. The findings of the study revealed good antenatal clinic attendance, availability of supplements and 93% compliance to the consumption of iron and folate supplements. High compliance to the consumption of iron and folate supplements by pregnant women was reported, and this should be reinforced.

    Full Text Available Abstract Background Folate and iron deficiency during pregnancy are risk factors for anaemia, preterm delivery, and low birth weight, and may contribute to poor neonatal health and increased maternal mortality. The World Health Organization recommends supplementation of folic acid (FA and iron for all pregnant women at risk of malnutrition to prevent anaemia. We assessed the use of prenatal folic acid and iron supplementation among women in a geographical area with a high prevalence of anaemia, in relation to socio-demographic, morbidity and health services utilization factors. Methods We analysed a cohort of 21,889 women who delivered at Kilimanjaro Christian Medical Centre (KCMC, Moshi, Tanzania, between 1999 and 2008. Logistic regression models were used to describe patterns of reported intake of prenatal FA and iron supplements. Results Prenatal intake of FA and iron supplements was reported by 17.2% and 22.3% of pregnant women, respectively. Sixteen percent of women reported intake of both FA and iron. Factors positively associated with FA supplementation were advanced maternal age (OR = 1.17, 1.02-1.34, unknown HIV status (OR = 1.54, 1.42-1.67, a diagnosis of anaemia during pregnancy (OR = 12.03, 9.66-14.98 and indicators of lower socioeconomic status. Women were less likely to take these supplements if they reported having had a malaria episode before (OR = 0.57, 0.53-0.62 or during pregnancy (OR = 0.45, 0.41-0.51, reported having contracted other infectious diseases (OR = 0.45, 0.42-0.49, were multiparous (OR = 0.73, 0.66-0.80, had preeclampsia/eclampsia (OR = 0.48, 0.38-0.61, or other diseases (OR = 0.55, 0.44-0.69 during pregnancy. Similar patterns of association emerged when iron supplementation alone and supplementation with both iron and FA were evaluated. Conclusions FA and iron supplementation are low among pregnant women in Northern Tanzania, in particular among women with co-morbidities before

    This analysis examined factors associated with non-use of antenatal iron/folic acid supplements in Indonesia. Data from the 2002/2003 and 2007 Indonesia Demographic and Health Surveys (IDHS) were used, providing survival information for 26,591 most recent deliveries over the five-year period prior to each survey. The main outcome variable was non-use of iron/folic acid supplements. Using logistic regression, we examined the role of external environment, predisposing, enabling, need factors, and previous utilization of other maternal care services in non-use of antenatal iron/folic acid supplements. Mothers from outer Java- Bali Region and rural areas (OR=1.73, 95% CI: 1.48-2.03) had increased odds for not using antenatal iron/folic acid supplements. The likelihood for not using the supplements increased with the reduction of household wealth index and parental education. The odds increased amongst mothers with low autonomy on her own health care (OR=1.24, 95% CI: 1.04-1.49), high birth-rank infants, mothers with low knowledge of obstetric complications and low exposure to mass media. Enabling factors associated with increased odds for non-use of iron/folic acid supplements included mothers reporting money to pay health services (OR=1.28, 95% CI: 1.13- 1.44) and distance to health services (OR=1.20, 95% CI: 1.02-1.40) were major problems. Our study demonstrated the importance of antenatal care as a distribution channel of the supplements. Increasing community awareness, coverage and access to health services along with strengthening counselling sessions during antenatal care and community participation in health programs are necessary to improve the uptake of iron/folic acid supplements, to increase infant survival in Indonesia.

    The effect of maternal iron status on fetal iron deposition is uncertain. We used a unique stable-isotope technique to assess iron transfer to the fetus in relation to maternal iron status. The study group comprised 41 Peruvian women. Of these women, 26 received daily prenatal supplements containing iron and folate (n = 11; Fe group) or iron, folate, and zinc (n = 15; Fe+Zn group) from week 10-24 of pregnancy to 1 mo postpartum. The remaining 15 women (control group) received iron supplementation only during the final month of pregnancy. During the third trimester of pregnancy (+/- SD: 32.9 +/- 1.4 wk gestation) oral 57Fe (10 mg) and intravenous 58Fe (0.6 mg) stable iron isotopes were administered to the women, and isotope enrichment and iron-status indicators were measured in cord blood at delivery. The net amount of 57Fe in the neonates' circulation (from maternal oral dosing) was significantly related to maternal iron absorption (P < 0.005) and inversely related to maternal iron status during the third trimester of pregnancy: serum ferritin (P < 0.0001), serum folate (P < 0.005), and serum transferrin receptors (P < 0.02). Significantly more 57Fe was transferred to the neonates in non-iron-supplemented women: 0.112 +/- 0.031 compared with 0.078 +/- 0.042 mg in the control group (n = 15) and the Fe and Fe+Zn groups (n = 24), respectively (P < 0.01). In contrast, 58Fe tracer in the neonates' circulation was not significantly related to maternal iron status. The transfer of dietary iron to the fetus is regulated in response to maternal iron status at the level of the gut.

    Iron, zinc, and calcium can interact with each other in a way that inhibits their respective absorption. On the other hand, mineral fortification has been used to improve simultaneous iron and zinc absorption from food supplements. We evaluated the effect of a novel fortificant mixture consisting of NaFeEDTA, zinc methionine, ascorbic acid, and citric acid on iron and zinc absorption from a dry food supplement designed for preschool children. The standard food supplement contained cereal and legume flour, dried milk, and a mixture of micronutrients including ferrous sulfate and zinc sulfate as sources of supplemental iron and zinc, respectively. Standard and novel food products were prepared as porridge with or without the addition of 200 mg Ca as calcium phosphate. Iron absorption and zinc absorption from the food products were evaluated simultaneously in 13 nonpregnant, adult women by extrinsically labeling the products with radioisotopes of iron and zinc and carrying out whole-body counting 7 d after the food products were consumed in random order. The absorption of iron from the NaFeEDTA-containing (novel) food product was 1.7 times that from the ferrous sulfate-containing (standard) product (P = 0.015). There was no significant effect of dietary calcium on iron absorption. Zinc absorption was not associated with the form of zinc consumed, but higher dietary calcium was marginally associated with lower zinc absorption (P = 0.071). A mixture of fortificants containing NaFeEDTA, zinc sulfate or zinc methionine, ascorbic acid, and citric acid, but without calcium, can improve iron and zinc absorption from food products. A cost-benefit analysis of the novel fortificant mixture needs to be performed.

    The objective of this study was to determine the effect of incrementally higher doses of iron on the zinc protoporphyrin to heme ratio (ZnPP/H) and serum ferritin, and developmental outcomes in premature infants at risk for iron deficiency. Infants eligible for this prospective, randomized blinded trial were between 27 and 30 completed weeks of gestation, older than 1 week of age and tolerating 100 ml kg(-1) per day of enteral feedings. The control group was treated with 2.2 mg kg(-1) per day of ferrous sulfate and the treatment group was treated with 3 to 12 mg kg(-1) per day based on the ZnPP/H. Infants had follow-up with Bayley exams at 6 and 24 months corrected age. Statistical evaluation included Student's t-tests and Fisher's exact test. Eighty-one infants were enrolled (40 control, 41 treatment). The average total iron dose for the control group was 2.2 mg kg(-1) per day and for the treatment group was 10.4 mg kg(-1) per day (PZnPP/H was not different between the two groups. The ferritin at the end of the study was decreased in the control group but remained stable in the treatment group (control initial 202±109 ng ml(-1), final 168±141 ng ml(-1) (PZnPP/H may not be a reliable marker of iron status when used in a short period of time during iron supplementation. Infants treated with a lower dose of ferrous sulfate had a decreasing serum ferritin and a trend toward increased motor delays at 24 months.

    The objective of this study was to compare the effect of once weekly iron supplementation (IS) versus twice weekly, on hemoglobin (Hb) levels and anemia prevalence. In this cluster-randomized clinical trial study, we evaluated infants aged 6-18 months. Length of intervention: 16 weeks. Infants were cluster randomized to either 25 mg elemental iron once weekly (Group-A) or twice weekly (Group-B). Primary outcome variables were change in Hb concentration and anemia prevalence. Two biochemical evaluations were performed to determine Hb concentrations, before and after intervention. For Group-A, at baseline, mean Hb concentration was 10.8 ± 1.18 g/dl and after intervention 11.2 ± 1.07 g/dl,p = 0.12; anemia prevalence was 52.5% at baseline and 37.5% after intervention,p = 0.18; Group-B, mean baseline Hb was 10.7 ± 1.04 g/dl, and 11.3 ± 0.91 g/dl after intervention,p = 0.002; anemia prevalence reduced from 57.9 to 36.8%. Both once and twice weekly IS increased mean Hb concentration; however, twice weekly supplementation provided more significant results. © The Author 2015. Published by Oxford University Press.

    deficiency anemia in children. Study Design: Randomized controlled trial. Place and Duration of Study: Paediatric department of Combined Military Hospital Kharian, Pakistan, from October 2011 to March 2013. Patients and Methods: In total 200 anemic children from 6 months to 5 years of age were included. Cut off value for Hb was < 8 gm/dl. Patients were divided into two groups, each of 100, randomly. Group A received oral sodium feredetate (iron edetate) and group B received intramuscular iron sorbitol. Rise in Hb > 10 gm/dl was kept as the desired value. Maximum duration of treatment planned was 12 weeks for group A and 2 weeks for group B. Laboratory parameters such as Hb%, mean corpuscular volume (MCV), retic count and serum ferritin level were used to detect the responses in both groups at one week, two weeks, four weeks and twelve weeks of treatment. Results: Among 200 patients, male and female distribution was 45% and 55% respectively. Desired rise in Hb in group B was achieved much earlier i.e. at two weeks as compared to group A. Progressive rise in laboratory parameters was observed but this rise was more evident in group B as compared to group A. After one week treatment in group A, rise in retic count, Hb, ferritin and MCV was 0.759 ± 0.318, 0.814 ± 0.387, 0.47 ± 0.154 and 4.28 ± 2.468 respectively. But rise in these values in group B was 2.235±0.632, 2.335 ± 0.135, 6.31 ± 1.123 and 12.11 ± 0.414 respectively. Same persistent different trend was observed at 2 and 4 weeks. After 12 weeks treatment in group A, rise in retic count, Hb, ferritin and MCV was 1.044 ± 0.222, 5.204 ± 0.134, 17.39 ± 2.551 and 16.61 ± 1.214 respectively but rise in these laboratory indices in group B was 0.551 ± 0.261, 6.097 ± 0.21, 42.49 ± 2.768 and 20.68 ± 2.233 respectively. The comparison of hematological indices after 12 weeks in A and B groups show significant differences. All these parameters improved in both groups but improvement in group B was drastically

    Hookworm infections are significant public health issues in South-East Asia. In women of reproductive age, chronic hookworm infections cause iron deficiency anaemia, which, upon pregnancy, can lead to intrauterine growth restriction and low birth weight. Low birth weight is an important risk factor for neonatal and infant mortality and morbidity. We investigated the association between neonatal birth weight and a 4-monthly deworming and weekly iron-folic acid supplementation program given to women of reproductive age in north-west Vietnam. The program was made available to all women of reproductive age (estimated 51,623) in two districts in Yen Bai Province for 20 months prior to commencement of birth weight data collection. Data were obtained for births at the district hospitals of the two intervention districts as well as from two control districts where women did not have access to the intervention, but had similar maternal and child health indicators and socio-economic backgrounds. The primary outcome was low birth weight. The birth weights of 463 infants born in district hospitals in the intervention (168) and control districts (295) were recorded. Twenty-six months after the program was started, the prevalence of low birth weight was 3% in intervention districts compared to 7.4% in control districts (adjusted odds ratio 0.29, 95% confidence interval 0.10 to 0.81, p = 0.017). The mean birth weight was 124 g (CI 68 - 255 g, pcontrol districts. The findings of this study suggest that providing women with regular deworming and weekly iron-folic acid supplements before pregnancy is associated with a reduced prevalence of low birth weight in rural Vietnam. The impact of this health system-integrated intervention on birth outcomes should be further evaluated through a more extensive randomised-controlled trial.

    Preconception micronutrient interventions may be a promising approach to reduce anemia and iron deficiency during pregnancy, but currently we have limited data to inform policies. We evaluated whether providing additional pre-pregnancy weekly iron-folic acid (IFA) or multiple micronutrient (MM) supplements compared to only folic acid (FA) improves iron status and anemia during pregnancy and early postpartum. We conducted a double blind randomized controlled trial in which 5011 Vietnamese women were provided with weekly supplements containing either only 2800 μg FA (control group), IFA (60 mg Fe and 2800 μg FA) or MM (15 micronutrients with similar amounts of IFA). All women who became pregnant (n = 1813) in each of the 3 groups received daily IFA (60 mg Fe and 400 μg FA) through delivery. Hematological indicators were assessed at baseline (pre-pregnancy), during pregnancy, 3 months post-partum, and in cord blood. Adjusted generalized linear models were applied to examine the impact of preconception supplementation on anemia and iron stores, using both intention to treat and per protocol analyses (women consumed supplements ≥ 26 weeks before conception). At baseline, 20% of women were anemic, but only 14% had low iron stores (ferritin population and identify effective interventions for reducing prenatal anemia. ClinicalTrials.Gov NCT01665378.

    Vitamin D deficiency has been associated with increased risk for cardiovascular disease and anemia. Vitamin D-related changes in lipid profile have been studied extensively but the relationship between vitamin D and lipid metabolism is not completely understood. As both vitamin D and intermittent training may potentially affect iron and lipid metabolism, the aim of the study was to evaluate whether a daily supplementation of vitamin D can modulate the response of hematological and lipid parameters to high-intensity interval training (HIIT) in soccer players. Thirty-six young elite junior soccer players were included in the placebo-controlled, double-blind study. Participants were non-randomly allocated into either a supplemented group (SG, n=20, HIIT and 5,000 IU of vitamin D daily) or placebo group (PG, n=16, HIIT and sunflower oil). Hematological parameters were ascertained before and after the 8-wk training. The change score (post- and pre-training difference) was calculated for each individual and the mean change score (MCS) was compared between SG and PG using the t test and analysis of covariance. There were no differences between SG and PG at baseline. The red and white cell count, hemoglobin, hematocrit, MCHC, ferritin, and HDL-cholesterol changed significantly over the 8-wk HIIT. However, no significant differences in MCS were observed between SG and PG for any variable. A daily vitamin D supplement did not have any impact on alteration in hematological or lipid parameters in young soccer players in the course of high-intensity interval training.

    The objective of this observational study was the early evaluation of the impact, a week after the first administration of epoetin alfa 40000 U once weekly and i.v. dose of 62.5 mg sodium ferric gluconate for seven days in improving hemoglobin levels in cancer patients affected by mild/moderate or severe anemia during chemotherapy. Twenty patients affected by solid tumors who received epoetin alfa 40000 U once weekly and daily i.v. sodium ferric gluconate for one week were evaluated: 90% of the patients showed hemoglobin increase, with a median level of hemoglobin increase of 0.73 g/L from baseline, and 50% of them showing a hemoglobin increase > 1 gr/L. The treatment was well tolerated and no adverse event was observed. The early increase of hemoglobin level from baseline is interesting and suggestive for the possibility of achieving an adequate hemoglobin level with a short-term treatment. It is still necessary to further explore the real need of iron supplementation to maintain adequate erythropoiesis prior and during epoetin therapy.

    The aim of the present study was to determine the effect of calcium phosphate and/or vitamin D₃ on bone and mineral metabolism. Sixty omnivorous healthy subjects participated in the double-blind, placebo-controlled parallel designed study. Supplements were tricalcium phosphate (CaP) and cholecalciferol (vitamin D₃). At the beginning of the study (baseline), all subjects documented their normal nutritional habits in a dietary record for three successive days. After baseline, subjects were allocated to three intervention groups: CaP (additional 1 g calcium/d), vitamin D₃ (additional 10 μg/d) and CaP + vitamin D₃. In the first two weeks, all groups consumed placebo bread, and afterwards, for eight weeks, the test bread according to the intervention group. In the last week of each study period (baseline, placebo, after four and eight weeks of intervention), a faecal (three days) and a urine (24 h) collection and a fasting blood sampling took place. Calcium, phosphorus, magnesium and iron were determined in faeces, urine and blood. Bone formation and resorption markers were analysed in blood and urine. After four and eight weeks, CaP and CaP + vitamin D₃ supplementations increased faecal excretion of calcium and phosphorus significantly compared to placebo. Due to the vitamin D₃ supplementations (vitamin D₃, CaP + vitamin D₃), the plasma 25-(OH)D concentration significantly increased after eight weeks compared to placebo. The additional application of CaP led to a significant increase of the 25-(OH)D concentration already after four weeks. Bone resorption and bone formation markers were not influenced by any intervention. Supplementation with daily 10 μg vitamin D₃ significantly increases plasma 25-(OH)D concentration. The combination with daily 1 g calcium (as CaP) has a further increasing effect on the 25-(OH)D concentration. Both CaP alone and in combination with vitamin D₃ have no beneficial effect on bone remodelling markers and on

    Iron deficiency is frequent among athletes. All types of iron deficiency may affect physical performance and should be treated. The main mechanisms by which sport leads to iron deficiency are increased iron demand, elevated iron loss and blockage of iron absorption due to hepcidin bursts. As a baseline set of blood tests, haemoglobin, haematocrit, mean cellular volume, mean cellular haemoglobin and serum ferritin levels help monitor iron deficiency. In healthy male and female athletes >15 years, ferritin values sports, a ferritin value of 50 mcg/l should be attained in athletes prior to altitude training, as iron demands in these situations are increased. Treatment of iron deficiency consists of nutritional counselling, oral iron supplementation or, in specific cases, by intravenous injection. Athletes with repeatedly low ferritin values benefit from intermittent oral substitution. It is important to follow up the athletes on an individual basis, repeating the baseline blood tests listed above twice a year. A long-term daily oral iron intake or i.v. supplementation in the presence of normal or even high ferritin values does not make sense and may be harmful.

    Full Text Available This study evaluated, in vitro, the effect of iron (previously exposed with enamel powder or added directly to the beverage on the erosive potential of carbonated or decarbonated beverage. Four sets of experiments were done. For groups E1 and E3, a solution containing 30 mmol/L FeSO4 was added to bovine enamel powder (particles between 75-106 mm before exposure to the carbonated or decarbonated beverage (Sprite Zero®, respectively. For groups E2 and E4, 15 mmol/L FeSO4 was added directly to the carbonated or decarbonated beverage, respectively. Control groups were included for comparison. In controls C1 and C3, the experiments E1 and E3 were repeated, but the iron solution was replaced by deionized water. For controls C2 and C4, the carbonated and decarbonated beverage, respectively, was used, without addition of iron. After addition of the beverage to the powdered enamel (40 mg enamel powder/400 mL of final volume, the sample was vortexed for 30 s and immediately centrifuged for 30 s (11,000 rpm. The supernatant was removed after 1 min 40 s. This procedure was repeated in quintuplicate and the phosphate released was analyzed spectrophotometrically. The results were analyzed by Student's t-test (p<0.05. E2 presented the best results with a significant inhibition (around 36% of phosphate released. For E3 and E4 a non-significant inhibition (around 4 and 12%, respectively, was observed. For E1 an increase in phosphate loss was detected. Thus, the protective effect of iron seems to be better when this ion is directly added to the carbonated beverage.

    Iron deficiency causes long-term adverse consequences for children and is the most common nutritional deficiency worldwide. Observational studies suggest that iron deficiency anemia protects against Plasmodium falciparum malaria and several intervention trials have indicated that iron supplementation increases malaria risk through unknown mechanism(s). This poses a major challenge for health policy. We investigated how anemia inhibits blood stage malaria infection and how iron supplementation abrogates this protection. This observational cohort study occurred in a malaria-endemic region where sickle-cell trait is also common. We studied fresh RBCs from anemic children (135 children; age 6-24months; hemoglobin Anemia substantially reduced the invasion and growth of both laboratory and field strains of P. falciparum in vitro (~10% growth reduction per standard deviation shift in hemoglobin). The population level impact against erythrocytic stage malaria was 15.9% from anemia compared to 3.5% for sickle-cell trait. Parasite growth was 2.4 fold higher after 49days of iron supplementation relative to baseline (panemia protects African children against falciparum malaria, an effect that is substantially greater than the protection offered by sickle-cell trait. Iron supplementation completely reversed the observed protection and hence should be accompanied by malaria prophylaxis. Lower hemoglobin levels typically seen in populations of African descent may reflect past genetic selection by malaria.

    Iron deficiency (ID), with or without anemia, is highly prevalent worldwide and has clinical consequences. The prevention and treatment of ID is a major public health goal. Accurate diagnosis, selection of the appropriate iron replacement therapy and addressing the underlying cause, remain as the main challenges in ID management. Areas covered: This review aims to provide a narrative review of current available evidence on iron supplementation options regularly used to treat ID, including oral and intravenous (IV) iron formulations, with emphasis on safety issues. Analyzed safety concerns include gastrointestinal side effects (oral iron) and risks of hypotension, anaphylaxis, infection, hypophosphatemia, oxidative stress and mortality (IV iron). Expert opinion: Low-to-moderate doses of oral iron supplementation remains as first line therapy for uncomplicated ID, but it has been scarcely discussed in the setting of inflammation. Confirmatory studies on the efficacy of newer oral iron formulations in this setting are needed. Compared with oral iron, short-term IV iron administration is more efficacious in ID correction, without significant safety concerns. However, long-term safety of IV iron maintenance therapy, head to head comparisons of IV iron preparations, pharmacological modulation of hepcidin and HIF, and extra-erythropoietic effects of iron are among the important areas of research.

In this study we aimed to determine the effectiveness of the program in reducing anaemia and the prevalence of hookworm infection after 72 months (six years.This prospective cohort study followed up a cohort of 389 women of child-bearing age from baseline until six years after the introduction of the weekly IFA (one tablet containing 200 mg ferrous sulphate, 0.4mg folic acid and deworming (one 400mg tablet of albendazole given twice yearly program (May 2006 to 2012. In each of the six surveys (baseline and five follow-up surveys we measured haemoglobin and ferritin, and the burden of soil transmitted helminth (STH infections, and in the 72 month survey we also administered a questionnaire to assess adherence and possible impediments to participating in the program.Two hundred and fifty six (65.8% of the original 389 women enrolled in the cohort attended the final 72 month survey. Haemoglobin levels were 122 g/L [95% C.I. 120, 124] at baseline and increased to 135g/L [95% C.I. 133, 138] after 72 months. The prevalence of anaemia was 37.8% [95% C.I. 31.0, 44.7] at baseline and reduced to 14.3% [95% C.I. 9.5, 19.1]. Hookworm infection prevalence, 75.9% [95% C.I. 68.1, 83.8] at baseline, reduced to 10.2% [95% C.I. 5.4, 15.0] with no moderate or heavy intensity infections. Seventy-two percent of participants reported still taking at least 75% of the weekly supplements, and 85.0% had taken the most recent deworming treatment.Anaemia rates fell significantly during the six-year program, and STH infections were eliminated as a public health risk. Adherence was well maintained but long-term sustainability is challenging in the absence of ongoing external support.

    Polyphenol-rich plant products as feed supplements have been shown to exert beneficial effects on feed efficiency in piglets. However, tannins as components of polyphenol-rich plant products are able to reduce the absorption of various trace elements. The present study investigated the effect of two polyphenol-rich dietary supplements, grape seed and grape marc meal extract (GME) and spent hops (SH), on iron (Fe), zinc (Zn) and copper (Cu) status in piglets supplied adequately with those trace elements. A trial with three groups of piglets which received a Control diet or the same diet supplemented with either 1% GME or 1% SH over a period of 4 weeks was performed. Concentrations of Fe, Zn and Cu in plasma, total iron binding capacity and saturation of transferrin in plasma did not differ between the three groups. Piglets fed the diet supplemented with SH showed no differences in the concentrations of Fe, Zn and Cu in the liver in comparison to the Control group. Piglets fed the diets supplemented with GME showed slightly lower concentrations of Zn and Cu in the liver than Control piglets (p < 0.05); however, concentrations of both elements remained in the physiological range. Overall, this study shows that the polyphenol-rich plant products GME and SH had marginal effect on the status of Fe, Zn and Cu in piglets.

    One in five maternal deaths are directly attributable to anaemia in the world. The World Health Organization recommends iron supplementation from the second trimester of pregnancy to 45 days after delivery. The aim of this study was to determine the compliance rate of iron-folate consumption and the factors associated with iron-folate consumption among post-natal mothers in Nepal. This study utilised the data of Nepal Demographic and Health Survey (NDHS) 2011. The NDHS 2011 is a cross sectional and nationally representative survey. Of the 4,148 respondents, only 20.7% consumed iron throughout the post-natal period for 45 days. Mothers who had higher and secondary education [adjusted Odd ratio (aOR) 3.101; 95% CI (2.268-4.240)]; had attended four or more antenatal care visits [aOR 9.406; 95% CI (5.552-15.938)]; lived in Far-western development region [aOR 1.822; 95% CI (1.387-2.395)]; delivered in health facility [aOR 1.335; 95% CI (1.057-1.687)]; and attended postnatal care [aOR 2.348; 95% CI (1.859-2.965)] were more likely to take iron for 45 days of postpartum. Intervention to increase the compliance with the postpartum iron-folate supplementation are required to avoid adverse pregnancy outcomes associated with poor iron status with especial focus on the mothers who delivered at homes and did not attend post-natal check up.

    In resource-limited settings without safe alternatives to breastfeeding, the WHO recommends exclusive breastfeeding and antiretroviral (ARV) prophylaxis. Given the high prevalence of anemia among HIV-infected women, mothers and their infants (through fetal iron accretion) may be at risk of iron deficiency. We assessed the effects of maternal micronutrient-fortified lipid-based nutrient supplements (LNS) and maternal ARV treatment or infant ARV prophylaxis on maternal and infant iron status during exclusive breastfeeding from birth to 24 weeks. The Breastfeeding, Antiretrovirals, and Nutrition study was a randomized controlled trial conducted in Lilongwe, Malawi, from 2004 to 2010. HIV-infected mothers (CD4 >200 cells/μL) and their infants were randomly assigned to 28-week interventions: maternal LNS/maternal ARV (n = 424), maternal LNS/infant ARV (n = 426), maternal LNS (n = 334), maternal ARV (n = 425), infant ARV (n = 426), or control (n = 334). Longitudinal models tested intervention effects on hemoglobin (Hb). In a subsample (n = 537) with multiple iron indicators, intervention effects on Hb, transferrin receptors (TfR), and ferritin were tested with linear and Poisson regression. In longitudinal models, LNS effects on maternal and infant Hb were minimal. In subsample mothers, maternal ARVs were associated with tissue iron depletion (TfR >8.3 mg/L) (risk ratio: 3.1, P 0.1). In subsample infants, interventions were not associated with impaired iron status (all P > 0.1). Maternal ARV treatment with protease inhibitors is associated with maternal tissue iron depletion; but LNS mitigates adverse effects. ARVs do not seem to influence infant iron status; however, extended use needs to be evaluated.

    To prevent pre-eclampsia in populations with insufficient dietary calcium (Ca) intake, the World Health Organisation (WHO) recommends routine Ca supplementation during antenatal care (ANC). WHO guidelines suggest a complex dosing regimen, requiring as many as 5 pill-taking events per day when combined with iron and folic acid (IFA) supplements. Poor adherence may undermine public health effectiveness, so simpler regimens may be preferable. This trial will compare the effect of the WHO-recommended (higher-dose) regimen vs. a simpler, lower-dose regimen on supplement consumption and pill-taking behaviours in Kenyan ANC clients. This is a parallel, non-inferiority, cluster-randomized trial; we examined 16 primary care health facilities in Kenya, 1047 pregnant women between 16-30 weeks gestational age. Higher-dose regimen: 1.5 g elemental calcium in 3 separate doses (500 mg Ca/pill) and IFA (60 mg Fe + 400 µg folic acid) taken with evening dose. Lower-dose regimen: 1.0 g calcium in 2 separate doses (500 mg Ca/pill) with IFA taken as above. Primary outcome is Ca pills consumed per day, measured by pill counts. Secondary outcomes include IFA pills consumed per day, client knowledge, motivation, social support, and satisfaction, measured at 4 to 10 weeks post-enrolment. Unit of randomization is the healthcare facility; unit of analysis is individual client. Intent-to-treat analysis will be implemented with multi-level models to account for clustering. If pregnant women prescribed lower doses of Ca ingest as many pills as women prescribed the WHO-recommended regimen, developing a lower-dose recommendation for antenatal Ca and IFA supplementation programs could save resources. Significance for public healthPre-eclampsia is a leading cause of maternal mortality. Based on clinical evidence of significant reduction in risk of pre-eclampsia, the WHO recommends including calcium (Ca) supplementation in antenatal care services in settings with inadequate dietary Ca intakes.

    Full Text Available BACKGROUND: To estimate the cost and cost-effectiveness of a project administering de-worming and weekly iron-folic acid supplementation to control anaemia in women of reproductive age in Yen Bai province, Vietnam. METHODS AND FINDINGS: Cost effectiveness was evaluated using data on programmatic costs based on two surveys in 2006 and 2009 and impact on anaemia and iron status collected in 2006, 2007, and 2008. Data on initial costs for training and educational materials were obtained from the records of the National Institute of Malariology, Parasitology and Entomology and the Yen Bai Malaria Control Program. Structured questionnaires for health workers at district, commune and village level were used to collect ongoing distribution and monitoring costs, and for participants to collect transport and loss of earnings costs. The cost per woman treated (defined as consuming at least 75% of the recommended intake was USD0.76 per annum. This estimate includes financial costs (for supplies, training, and costs of health care workers' time. Prevalence of anaemia fell from 38% at baseline, to 20% after 12 months. Thus, the cost-effectiveness of the project is assessed at USD 4.24 per anaemia case prevented per year. Based on estimated productivity gains for adult women, the benefit:cost ratio is 6.7∶1. Cost of the supplements and anthelminthics was 47% of the total, while costs of training, monitoring, and health workers' time accounted for 53%. CONCLUSION: The study shows that weekly iron-folic acid supplementation and regular de-worming is a low-cost and cost-effective intervention and would be appropriate for population-based introduction in settings with a high prevalence of anaemia and iron deficiency and low malaria infection rates.

    Food iron fortification can be a good strategy to prevent iron deficiency. Iron bioavailability from cocoa powder enriched with ferric pyrophosphate encapsulated in liposomes or ferrous fumarate was assessed in rats. Three groups of rats consumed during 28 days either a control diet or two diets prepared with ferric pyrophosphate- or ferrous fumarate-enriched cocoa powder as the unique source of iron. Body weight and food intake were monitored and last-week feces were collected. On day 28, animals were sacrificed and livers and spleens were removed. Hemoglobin and total iron binding capacity (TIBC) were determined. There were no significant differences in body weight and food intake. Apparent iron absorption and % absorption/intake were significantly lower in rats consuming enriched cocoa compared to the control group, without significant differences due to the iron form. Enriched cocoa groups showed significantly lower spleen iron content and concentration than the control. Liver iron was lower in the ferric pyrophosphate group compared to the other two groups. Hemoglobin and TIBC values showed a deficient iron status in ferric pyrophosphate rats. Cocoa powder is a good vehicle for iron fortification when enriched with ferrous fumarate compared to ferric pyrophosphate encapsulated in liposomes. Copyright 2007 S. Karger AG, Basel.

    All IV iron complexes carry a risk of potentially fatal allergic type hypersensitivity reactions. The mechanism(s) behind these reactions is unknown but the limited data available suggests that classic IgE mediated allergy is exceedingly rare, if ever occurring. Iron-carbohydrate molecules are complex nano-particles and trying to reduce the risk of serious hypersensitivity to antibody binding of an artificial antibody seems meaningless. A recently published analysis of safety data from randomized clinical trials confirms the method reported by Neiser to be useless to predict reaction risk. In conclusion, the study by Neiser et al. is biased, contains no new information, and has no clinical relevance. We are concerned that the association of the authors with a commercial entity has caused a conflict of interest that biases not only the results, but the entire experimental setup against competitors.

    Iron, calcium, zinc and phytic acid contents in vegetable blends from wheat, corn and soy were determined. Wheat and corn substitution with soy in compound products, gave an important amount of iron and calcium to the blends, while the initial content of phytic acid in wheat and corn was not significantly modified. Dehulling and enzymatic inactivation technological processes denoted a rather low influence on soy mineral content. In a similar way, the extrusion-cooking process did not affect appreciably the soluble iron content in blends. Soy incorporation greatly decreased in vitro iron availability in vegetable blends, while fortification with mineral blends slightly interfered, decreasing iron availability with regard to iron-fortified vegetable blends.

    The present literature review aimed to review the evidence for community-based distribution (CBD) of iron-folic acid (IFA) supplementation as a feasible approach to improve anaemia rates in low- and middle-income countries. The literature review included peer-reviewed studies and grey literature from PubMed, Cochrane Library, LILAC and Scopus databases. Low- and middle-income countries. Non-pregnant women, pregnant women, and girls. CBD programmes had moderate success with midwives and community health workers (CHW) who counselled on health benefits and compliance with IFA supplementation. CHW were more likely to identify and reach a greater number of women earlier in pregnancy, as women tended to present late to antenatal care. CBD channels had greater consistency in terms of adequate supplies of IFA in comparison to clinics and vendors, who faced stock outages. Targeting women of reproductive age through school and community settings showed high compliance and demonstrated reductions in anaemia. CBD of IFA supplementation can be a valuable platform for improving knowledge about anaemia, addressing compliance and temporary side-effects of IFA supplements, and increasing access and coverage of IFA supplementation. Programmatic efforts focusing on community-based platforms should complement services and information provided at the health facility level. Provision of training and supportive supervision for CHW on how to counsel women on benefits, side-effects, and when, why, and how to take IFA supplements, as part of behaviour change communication, can be strengthened, alongside logistics and supply systems to ensure consistent supplies of IFA tablets at both the facility and community levels.

    Full Text Available Iron deficiency and anemia affect approximately half of the chronic heart failure patients and they are associated with increased hospitalization rate, lower functional capacity, lower quality of life, and higher mortality. The exact mechanism of iron deficiency in heart failure patients is still not fully understood. Current guidelines recommend ferritin as the most accurate serum biomarker for the diagnosis of iron deficiency. The use of erythropoiesis-stimulating agents is no longer recommended because of the lack of improvement on mortality or hospital readmission rate, and it was associated with a higher rate of thromboembolic events. Intravenous iron replacement therapy is safe and generally well tolerated, with fewer side effects compared to oral administration. Large randomized studies with ferric carboxymaltose demonstrated its effectiveness and superiority to oral administration, and it was associated with a decreased rate of hospitalization rate and worsening heart failure, and improvement of functional capacity and quality of life. Intravenous iron supplementation for chronic heart failure is strongly recommended by European guidelines. Further studies are needed for a better knowledge of this complex pathology and determination of the long-term safety and effectiveness of iron administration in chronic heart failure patients. .

When combined, TT vaccination with IFA supplementation, and TT vaccination without IFA supplementation were protective across all groups.The study found that ANC, IFA supplementation, and TT vaccination during pregnancy reduced the likelihood of child mortality in Bangladesh. The findings suggest that considerable gains in improving child survival could be achieved through ensuring universal coverage of ANC, promoting TT vaccination during pregnancy and IFA supplementation among pregnant women in Bangladesh.

Materials and Methods: Term singleton healthy 6 month old infants were recruited from the Colombo Municipal Area. An interviewer administered pre-tested questionnaire, was used to collect data on their basic information and feeding practices. Baseline vitamin A, haemoglobin, serum ferritin and C-reactive protein were assessed. Children were given 100,000 units of vitamin A orally and 3mg/kg daily dose of iron till 9 months of age and all assessments were repeated. Serum retinol concentration was assessed by reverse phase HPLC. Baseline information was analyzed for n = 95 babies, 53 boys) at 6 months and paired data(n = 53) to analyze effects of intervention. Babies were divided into those with and without MAM at 6 months. Student’s t test was used to compare. Results: At 6 months, the mean weight was 7.1±1.0kg with SDS of -0.72±1.1, and length was 68.1±3.4cm with SDS of 0.61±1.5. 30 babies had MAM at 6 months (out of 95). Mean vitamin A level was 34.8±7.9μg/dl and the mean haemoglobin was 11.4±0.98g/dl. Two babies had low vitamin A levels(<20μg/dl) and 41 were anaemic<11.0g/dl). Mean serum ferritin was 21.7±19.6μg/l at 6 months(data of 82 babies) and 56 had low levels (<12μg/l). Of the 53 pairs with pre and post intervention data, MAM was present in 16 at 6 months and 19 at 9 months. Of the latter, 6 babies had developed MAM during the study period. This change was significant (p< 0.001) against only 3 babies who overcame MAM at post intervention.

    Iron refractory iron deficiency anemia is a hereditary recessive anemia due to a defect in the TMPRSS6 gene encoding Matriptase-2. This protein is a transmembrane serine protease that plays an essential role in down-regulating hepcidin, the key regulator of iron homeostasis. Hallmarks of this disease are microcytic hypochromic anemia, low transferrin saturation and normal/high serum hepcidin values. The anemia appears in the post-natal period, although in some cases it is only diagnosed in adulthood. The disease is refractory to oral iron treatment but shows a slow response to intravenous iron injections and partial correction of the anemia. To date, 40 different Matriptase-2 mutations have been reported, affecting all the functional domains of the large ectodomain of the protein. In vitro experiments on transfected cells suggest that Matriptase-2 cleaves Hemojuvelin, a major regulator of hepcidin expression and that this function is altered in this genetic form of anemia. In contrast to the low/undetectable hepcidin levels observed in acquired iron deficiency, in patients with Matriptase-2 deficiency, serum hepcidin is inappropriately high for the low iron status and accounts for the absent/delayed response to oral iron treatment. A challenge for the clinicians and pediatricians is the recognition of the disorder among iron deficiency and other microcytic anemias commonly found in pediatric patients. The current treatment of iron refractory iron deficiency anemia is based on parenteral iron administration; in the future, manipulation of the hepcidin pathway with the aim of suppressing it might become an alternative therapeutic approach.

    Full Text Available All IV iron complexes carry a risk of potentially fatal allergic type hypersensitivity reactions. The mechanism(s behind these reactions is unknown but the limited data available suggests that classic IgE mediated allergy is exceedingly rare, if ever occurring. Iron–carbohydrate molecules are complex nano-particles and trying to reduce the risk of serious hypersensitivity to antibody binding of an artificial antibody seems meaningless. A recently published analysis of safety data from randomized clinical trials confirms the method reported by Neiser to be useless to predict reaction risk. In conclusion, the study by Neiser et al. is biased, contains no new information, and has no clinical relevance. We are concerned that the association of the authors with a commercial entity has caused a conflict of interest that biases not only the results, but the entire experimental setup against competitors.

    Full Text Available Background: Anemia during adolescence affects growth and development of girls and boys increasing their vulnerability to dropping out-of-school. Hence investing in preventing anemia during adolescence is critical for their survival, growth and development. Objective: To find out the burden of anemia on adolescent age group in the tribal area of Jhagadia block and to assess the change in the hemoglobin level through the weekly Iron and Folic Acid IFA (DOTS directly observed treatment supplementation under Supervision by Peer Educators at Community level among adolescents. Methods: Community based intervention study conducted with adolescents (117 girls and 127 boys aged 10-19 years, through supplementation of IFA (DOTS by trained Peer Educators for 52 weeks in 5 tribal villages of Jhagadia. Hemoglobin level was determined by HemoCue method before and after intervention and sickle cell anemia by Electrophoresis method. Primary data on hemoglobin and number of tablets consumed was collected and statistically analyzed in SPSS 16.0 software by applying paired t-test. Results: The overall findings suggest that the prevalence of anemia reduced from 79.5% to 58% among adolescent girls and from 64% to 39% among boys. Mean rise of hemoglobin seen was 1.5 g/dl among adolescent boys and 1.3 g/dl among girls. A significant association was found in change in hemoglobin before and after intervention (P = 0.000 Conclusion: Prevalence of anemia among girls and boys can be reduced in their adolescent phase of life, through weekly supplementation of iron folic acid tablets under direct supervision and Nutrition Education by Peer Educator at community level.

    The scope of this work was to evaluate the implementation of the National Iron Supplementation Program (NISP) in Viçosa in the State of Minas Gerais and its impact on 6- to 18-month-old non-anemic infants assisted by the Family Health Teams. Interviews were conducted with the professionals and with the children's mothers/guardians. The non-anemic children who didn't receive the earlier supplementation (n=133) were given ferrous sulphate syrup for six months. Hemoglobin dosage, anthropometric evaluation and a socioeconomic survey were conducted before and after the six-month period. Children who ingested 75% or more of the prescribed dosage were classified as high adhesion, while the others were classified as low adhesion, according to the mothers' testimonials. With respect to the implementation in the city, the distribution system was not always available to the priority group and there was a lack of training and motivation on the part of most Community Health Agents. The lack of promotion of NISP among the priority group was detected, apart from a mothers' awareness drive. Regarding diet supplementation, children showed low adhesion and the dosage wasn't effective in preventing anemia. Therefore, important operational barriers to implementation were observed.

    Full Text Available Background: To prevent pre-eclampsia in populations with insufficient dietary calcium (Ca intake, the World Health Organisation (WHO recommends routine Ca supplementation during antenatal care (ANC. WHO guidelines suggest a complex dosing regimen, requiring as many as 5 pill-taking events per day when combined with iron and folic acid (IFA supplements. Poor adherence may undermine public health effectiveness, so simpler regimens may be preferable. This trial will compare the effect of the WHO-recommended (higher-dose regimen vs. a simpler, lower-dose regimen on supplement consumption and pill-taking behaviours in Kenyan ANC clients. Design and methods: This is a parallel, non-inferiority, cluster-randomized trial; we examined 16 primary care health facilities in Kenya, 1047 pregnant women between 16-30 weeks gestational age. Higher-dose regimen: 1.5 g elemental calcium in 3 separate doses (500 mg Ca/pill and IFA (60 mg Fe + 400 μg folic acid taken with evening dose. Lower-dose regimen: 1.0 g calcium in 2 separate doses (500 mg Ca/pill with IFA taken as above. Measurements: Primary outcome is Ca pills consumed per day, measured by pill counts. Secondary outcomes include IFA pills consumed per day, client knowledge, motivation, social support, and satisfaction, measured at 4 to 10 weeks post-enrolment. Statistical analyses: Unit of randomization is the health-care facility; unit of analysis is individual client. Intent-to-treat analysis will be implemented with multi-level models to account for clustering. Expected public health impact: If pregnant women prescribed lower doses of Ca ingest as many pills as women prescribed the WHO-recommended regimen, developing a lower-dose recommendation for antenatal Ca and IFA supplementation programs could save resources.

    Full Text Available Ferulic acid is a polyphenolic compound contained in various types of fruits and wheat bran. As a salt of the active ingredient, sodium ferulate (SF has potent free radical scavenging activity and can effectively scavenge ROS. In this study, we examined the effect of SF on iron-overloaded mice in comparison to a standard antioxidant, taurine (TAU. We determined the protective role of SF against liver injury by examining liver-to-body ratio (%, transaminase and hepatocyte apoptosis in rats supplied with 10% dextrose intraperitoneal injection. In addition, antioxidative enzymes activities, ROS formation, mitochondrial swelling, and mitochondrial membrane potential (MMP were all evaluated to clarify the mechanism of protective effect of SF associated with oxidative stress. After 15 weeks of SF treatment, we found a significant reduction in liver-to-body weight radio and elevation in both transaminase and hepatocyte apoptosis associated with iron-injected to levels comparable to those achieved with TAU. Both SF and TAU significantly attenuated the impaired liver function associated with iron-overloaded in mice, whereas neither showed any significant effect on the iron uptake. Furthermore, treatment with either SF or TAU in iron-overloaded mice attenuated oxidative stress, associated with elevated oxidant enzymes activities, decreased ROS production, prevented mitochondrial swelling and dissipation of MMP and then inhibited hepatic apoptosis. Taken together, the current study shows that, SF alleviated oxidative stress and liver damage associated with iron-overload conditions compared to the standard ROS scavenger (TAU, and potentially could encourage higher consumption and utilization as healthy and sustainable ingredients by the food and drink.

    .5%, megaloblastic in 10.0% and dimorphic in 1.2%. Serum ferritin estimation performed on subjects having smear suggestive of iron deficiency led us to conclude that 16.1% had low serum ferritin levels and iron-deficiency anaemia. Statistically significant association of iron-deficiency anaemia was found with age, nutritional status, passage of worms in stool and lack of in-house toilet. Conclusion: Prevalence of anaemia as well as iron deficiency anaemia is low in adolescent boys and therefore is not a public health problem in this section of society. Providing iron supplements may not be warranted to them as is currently being done. More research is needed to identify the cause of such anaemia.

    Low birth weight (LBW) is a major cause of neonatal deaths in developing countries including Nepal. Its social determinants in Nepal have rarely been identified. This study aimed to identify the factors associated with low birth weight among under-five children comparing data from the Nepal Demographic and Health Surveys (NDHS) of 2006 and 2011. Pooled data from the Nepal Demographic and Health Surveys (NDHS) of 2006 and 2011 were analysed initially and the two survey data were then compared separately. The association between LBW and socio-demographic and health related factors were analysed using multiple logistic regression analysis with a stepwise backward elimination procedure. Complex Sample Analysis method was used to account for study design and sampling. A total of 2845 children, 923 children in 2006 and 1922 children in 2011, had their birth weight recorded. The mean birth weight was 3024 (SD = 654.5) grams. A total of 12.1% (95% Confidence interval (CI); 10.6%-13.7%) children had low birth weight (birth. Attending antenatal care was found to be consistently associated with low birth weight for the pooled survey data, and both 2006 and 2011 survey data, respectively. Not attending antenatal care increased the odds of having a LBW infant by more than two times [OR 2.301; 95% CI (1.526-3.471)]. Iron supplementation, which is an integral part of antenatal care in Nepal, was also significantly associated with birth weight for combined and individual surveys. Mothers not consuming iron supplementation during their pregnancy were more likely to have LBW infants [OR 1.839; 95% CI (1.282-2.363)]. Residing in the Far-western and Eastern region were also significant risk factors for LBW in the pooled dataset and in 2011 survey. The current study indicated there was no significant decrease in the LBW prevalence and there is a need of targeted interventions aimed at decreasing the high rate of LBW through increasing antenatal care and consumption of iron

    Infants, young children, and childbearing aged women are particularly exposed to iron deficiency. Pregnancy further increases iron requirements. Nevertheless the consequences of anemia and/or iron deficiency on pregnancy outcome, development of the foetus and postnatal iron status of the infant, remain to be determined. There is a 3-fold increase of premature deliveries in iron deficient anemic pregnant women whose anemia is discovered in early pregnancy: however this increased risk of premature delivery is not observed when iron deficiency anemia is discovered in late pregnancy. Iron supplementation during pregnancy improves the maternal hematological parameters but it is still unclear whether it also improves the maternal health and the pre and postnatal development of the child. Based on our actual knowledge, iron supplementation during pregnancy is to be recommended in risk groups only (ie mainly adolescents, low income women, women with multiple pregnancies), using ferrous iron at a dosage of 30 mg per day.

    A community-based, cluster-randomized, placebo-controlled trial of daily zinc and/or iron+folic acid supplementation was conducted in rural southern Nepal to examine motor milestone attainment among 3264 children 1-36 mo of age between 2001 and 2006. Treatment groups included placebo, zinc (10 mg), iron+folic acid (12.5 mg iron + 50 microg folic acid), and zinc+iron+folic acid (10 mg zinc + 12.5 mg iron + 50 microg folic acid). Infants received half of these doses. The iron arms were stopped November 2003 by recommendation of the Data Safety and Monitoring Board; zinc and placebo continued until January 2006. A total of 2457 children had not walked at the time of entry into the trial and 1775 were followed through 36 mo. Mean age at first walking unassisted did not differ among groups and was 444 +/- 81 d (mean +/- SD) in the placebo group, 444 +/- 81 d in the zinc group, 464 +/- 85 d in the iron+folic acid group, and 446 +/- 87 d in the iron+folic acid+zinc group. Results were similar after adjustment for age at enrollment, asset ownership, maternal literacy, and prior child deaths in the household and in children who consumed at least 60 tablets. Compared with placebo, iron+folic acid was associated with an adjusted mean delay of 28.0 d (95% CI: 11.3, 44.7) in time to walking among infants and the delay was more pronounced with mid-upper arm circumference (MUAC) < 9.5 cm [60.6 d, (95% CI: 28.5, 92.6)]. Risks and benefits of universal iron+folic acid supplementation of infants beyond improved hematologic status deserve further consideration.

    Full Text Available The benefit of oral iron therapy (OIT and factors predictive of OIT response are not established in hemodialysis (HD patients with iron deficiency anemia (IDA. We examined the values of hepcidin-25, mean corpuscular volume (MCV, and ferritin as predictors of OIT response. Oral ferrous fumarate (50 mg/day, 8 weeks was given to 51 HD patients with IDA (hemoglobin (Hb < 12 g/dL, ferritin < 100 ng/mL treated with an erythropoietin activator. Sixteen patients were responders (improvement of Hb (ΔHb ≥ 2 g/dL and 35 were non-responders (ΔHb < 2g/dL. Baseline Hb, MCV, serum hepcidin-25, ferritin, iron parameters, and C-reactive protein (CRP before and ΔHb after OIT were compared between groups. Hepcidin-25, MCV, ferritin, and transferrin saturation were lower in the responders than in the non-responders. Hepcidin-25 positively correlated with ferritin. Hepcidin-25, MCV, and ferritin positively correlated with baseline Hb and negatively correlated with ΔHb. Despite normal CRP levels in all patients, CRP correlated positively with hepcidin-25 and ferritin. Stepwise multiple linear regression analysis and receiver operating characteristics curve analysis revealed that hepcidin-25, MCV, and ferritin could predict OIT response. We conclude that hepcidin-25, MCV, and ferritin could be useful markers of iron storage status and may help predict OIT response in HD patients.

    Nonalcoholic steatohepatitis (NASH) is characterized by combined pathology of steatosis, lobular inflammation, fibrosis, and hepatocellular degeneration, with systemic symptoms of diabetes or hyperlipidemia, all in the absence of alcohol abuse. Given the therapeutic importance and conflicting findings regarding the potential for healing the histopathologic features of NASH in humans, particularly fibrosis, we investigated the reversibility of NASH-related findings in Wistar rats fed a choline-deficient and iron-supplemented L-amino acid-defined (CDAA) diet for 12 weeks, with a recovery period of 7 weeks, during which the diets were switched to a choline-sufficient and iron-supplemented L-amino acid-defined (CSAA) one. Analysis showed that steatosis and inflammation were significantly resolved by the end of the recovery period, along with decreases in AST and ALT activities within 4 weeks. In contrast, fibrosis remained even after the recovery period, to an extent similar to that in continuously CDAA-fed animals. Real-time reverse transcriptase-polymerase chain reaction, Western blot, and immunohistochemical investigations revealed that expression of some factors indicating oxidative stress (CYP2E1, 4-HNE, and iNOS) were elevated, whereas catalase and SOD1 were decreased, and a hypoxic state and CD34-positive neovascularization were evident even after the recovery period, although the fibrogenesis pathway by activated α-SMA-positive hepatic stellate cells via TGF-β and TIMPs decreased to the CSAA group level. In conclusion, persistent fibrosis was noted after the recovery period of 7 weeks, possibly due to sustained hypoxia and oxidative stress supposedly caused by capillarization. Otherwise, histopathological features of steatosis and inflammation, as well as serum AST and ALT activities, were recovered. - Highlights: ► NASH-like liver lesions are induced in rats by feeding a CDAA diet. ► Steatosis and lobular inflammation are resolved after switching to a

    The aim of this study was to measure the content of calcium, magnesium, iron, zinc, and copper and determine the bioavailability of these ingredients in gluten-free breads fortified with milk and selected seeds. Due to the increasing prevalence of celiac disease and mineral deficiencies, it has become necessary to produce food with higher nutritional values which maintains the appropriate product characteristics. This study was designed for gluten-free breads fortified with milk and seeds such as flax, poppy, sunflower seeds, pumpkin seeds or nuts, and flour with amaranth. Subsequently, digestion was performed in vitro and the potential bioavailability of the minerals was measured. In the case of calcium, magnesium, iron, and copper, higher bioavailability was observed in rice bread, and, in the case of copper and zinc, in buckwheat bread. This demonstrated a clear increase in bioavailability of all the minerals when the bread were enriched. However, satisfactory results are obtained only for the individual micronutrients.

    The effect of iron-fortified cow's milk on body 59 Fe and 54 Mn retention and selective tissue distribution has been studied in newborn rats. Six-day old rats, divided into three groups were artificially fed for 7 hrs 0,45 ml of cow's milk or cow's milk enriched with either 52 or 103 μg of Fe /ml and marked with 59 Fe and 54 Mn. After 4 days there was no significant difference in whole body or carcass activity between the groups. Iron added to milk in large amounts did not influence body 59 Fe or 54 Mn retention in newborn rats, whereas it enhanced 59 Fe deposition in the liver and the intestinal wall and, to a lesser extent, 54 Mn deposition in the liver

    Depletion of iron stores is frequently seen in male and female distance runners. Possible causes of this iron depletion include inadequate iron intake especially among females and increased iron excretion through sweating and gastrointestinal blood loss. Animal studies suggest that iron deficiency without anemia can reduce endurance by lowering tissue cytochromes and the activity of certain muscle tissue enzymes. Iron supplementation appears to be beneficial in reducing blood lactate concentrations following heavy exercise. The amount of iron in the supplement appears to influence the amount of increase in hemoglobin and serum ferritin.

    Iron deficiency (ID) is associated with adverse outcomes in heart failure (HF) but the underlying mechanisms are incompletely understood. Intracellular iron availability is secured by two mRNA-binding iron-regulatory proteins (IRPs), IRP1 and IRP2. We generated mice with a cardiomyocyte-targeted deletion of Irp1 and Irp2 to explore the functional implications of ID in the heart independent of systemic ID and anaemia. Iron content in cardiomyocytes was reduced in Irp-targeted mice. The animals were not anaemic and did not show a phenotype under baseline conditions. Irp-targeted mice, however, were unable to increase left ventricular (LV) systolic function in response to an acute dobutamine challenge. After myocardial infarction, Irp-targeted mice developed more severe LV dysfunction with increased HF mortality. Mechanistically, the activity of the iron-sulphur cluster-containing complex I of the mitochondrial electron transport chain was reduced in left ventricles from Irp-targeted mice. As demonstrated by extracellular flux analysis in vitro, mitochondrial respiration was preserved at baseline but failed to increase in response to dobutamine in Irp-targeted cardiomyocytes. As shown by 31P-magnetic resonance spectroscopy in vivo, LV phosphocreatine/ATP ratio declined during dobutamine stress in Irp-targeted mice but remained stable in control mice. Intravenous injection of ferric carboxymaltose replenished cardiac iron stores, restored mitochondrial respiratory capacity and inotropic reserve, and attenuated adverse remodelling after myocardial infarction in Irp-targeted mice but not in control mice. As shown by electrophoretic mobility shift assays, IRP activity was significantly reduced in LV tissue samples from patients with advanced HF and reduced LV tissue iron content. ID in cardiomyocytes impairs mitochondrial respiration and adaptation to acute and chronic increases in workload. Iron supplementation restores cardiac energy reserve and function in iron

Secondary data analysis of the 2002-03, 2007 and 2012 Indonesia Demographic and Health Survey. Analysis of the association between factors associated with adherence (consuming ≥90 IFA tablets), including the women's knowledge and family support, was performed using multivariate logistic regression. National household survey. Women (n 19 133) who had given birth within 2 years prior to the interview date. Knowledge of pregnancy-related risks was associated with increased adherence to IFA supplementation (adjusted OR=1·8; 95 % CI 1·6, 2·0), as was full family (particularly husband's) support (adjusted OR=1·9; 95 % CI 1·6, 2·3). Adequate antenatal care (ANC) visits (i.e. four or more) was associated with increased adherence (adjusted OR=2·2; 95 % CI 2·0, 2·4). However, ANC providers missed opportunities to distribute tablets and information, as among women with adequate ANC visits, 15 % reported never having received/bought any IFA tablets and 30 % had no knowledge of pregnancy-related risks. A significant interaction was observed between family support and the women's educational level in predicting adherence. Family support significantly increased the adherence among women with knowledge of pregnancy-related risks and involving family members, particularly the husband and importantly for less-educated women, improved adherence to IFA supplementation. ANC visit opportunities must be optimized to provide women with sufficient numbers of IFA tablets along with health information (especially on pregnancy-related risks) and partner support counselling.

    Effective ammonium (NH4+) removal has been a challenge in wastewater treatment processes. Aeration, which is required for the conventional NH4+ removal approach by ammonium oxidizing bacteria, is an energy intensive process during the operation of wastewater treatment plant. The efficiency of NH4+ oxidation in natural systems is also limited by oxygen transfer in water and sediments. The objective of this study is to enhance NH4+ removal by applying a novel microbial process, anaerobic NH4+ oxidation coupled to iron (Fe) reduction (also known as Feammox), in constructed wetlands (CW). Our studies have shown that an Acidimicrobiaceae bacterium named A6 can carry out the Feammox process using ferric Fe (Fe(III)) minerals like ferrihydrite as their electron acceptor. To investigate the properties of the Feammox process in CW as well as the influence of electrodes, Feammox bacterium A6 was inoculated in planted CW mesocosms with electrodes installed at multiple depths. CW mesocosms were operated using high NH4+ nutrient solution as inflow under high or low sediment Fe(III) level. During the operation, NH4+ and ferrous Fe concentration, pore water pH, voltages between electrodes, oxidation reduction potential and dissolved oxygen were measured. At the end of the experiment, CW sediment samples at different depths were taken, DNAs were extracted and quantitative polymerase chain reaction and pyrosequencing were performed to analyze the microbial communities. The results show that the high Fe level CW mesocosm has much higher NH4+ removal ability than the low Fe level CW mesocosm after Fe-reducing conditions are developed. This indicates the enhanced NH4+ removal can be attributed to elevated Feammox activity in high Fe level CW mesocosm. The microbial community structures are different in high or low Fe level CW mesocosms and on or away from the installed electrodes. The voltages between cathode and anode increased after the injection of A6 enrichment culture in low Fe

    Full Text Available This paper discusses the potential to enhance the anaerobic digestion of food waste FW by supplementing trace elements (Fe, Co, Ni, Zn, Mn, Cu, Se, and Mo individually as well as in cocktails. A series of batch experiments on the biomethane potential of synthetic food waste were performed with low (FW-A and high (FW-B trace element background concentrations prepared in, respectively, Delft (The Netherlands and Tampa (Florida, USA. The most effective trace elements for FW-A were Fe with an increase of 39.2 (± 0.6 % of biomethane production, followed by Se (34.1 ± 5.6 % increase, Ni (26.4 ± 0.2 % increase and Co (23.8 ± 0.2 % increase. For FW-B supplementing these trace elements did not result in enhancement of the biomethane production, except for Se. FW-B had a Se concentration of 1.3 (± 0. 5 µg/gTS, while it was below the detection limit for FW-A. Regardless of the FW source, Se resulted in 30 – 35% increase of biomethane production at a concentration range of 25-50 µg/L (0.32 – 0.63 µM. Volatile fatty acids analysis revealed that TE supplementation enhances their consumption, thus yielding a higher biomethane production. Moreover, additional experiments on sulfide inhibition showed the enhancing effects of trace elements on the anaerobic digestion of food waste were not related with sulfide toxicity, but with the enzymatic reactions and/or microbial biomass aggregation.

    In India, 75% of children hemoglobin response with two dosages of daily (20 mg iron and 100 μg folic acid, or 40 mg iron and 200 μg folic acid) and weekly (40 mg iron and 200 μg folic acid) IFA supplementation in children of 3-5 years of age with mild or moderate anemia (hemoglobin 7-10 g/dl). Community-based cluster randomized control trial in nine adjoining Anganwadi Centers. Four hundred twenty six enrolled participants received directly supervised IFA tablet supplementation as per the above three groups. After 100 days, the number of available subjects in the NNACP daily dose (A), daily dose doubled (B) and weekly dose (C) groups were 112, 114 and 110, respectively. Hemoglobin was estimated at baseline, 50 and 100 days by the Cynmeth hemoglobin method. At 50 days, there were no differences between the three groups, but at 100 days, adjusted hemoglobin was lowered with weekly supplementation. The mean (95% confidence interval) hemoglobin (g/dl) differences were: (i) A-B: -0.05 (-0.17, 0.05), (ii) A-C: -0.38 (-0.50, -0.27) and (iii) B-C: -0.33, (-0.45, -0.21). Anemia reduction was 18.8%, 18.4% and 10.9%, respectively, in the three groups. Directly supervised IFA supplementation at the NNACP or double dose is equally efficacious but superior to weekly regimen.

    The increasing prevalence of obesity and sedentary lifestyles has led to a higher incidence of metabolic syndrome (MetS) worldwide as well as in Taiwan. Middle-aged women are at a greater risk of MetS, type 2 diabetes, and cardiovascular disease than men because they have more subcutaneous fat and larger waist circumferences compared with men with equal visceral fat levels. In this study, we investigated the effects of calorie restriction (CR) and fish oil supplementation (CRF) on middle-aged Taiwanese women with MetS. An open-label, parallel-arm, controlled trial was conducted for 12 weeks. A total of 75 eligible participants were randomly assigned to the CR or CRF group. Both the dietary intervention groups were further divided into two age groups: ≤45 and >45 years. Changes in MetS severity, inflammatory status, iron status, and red blood cell fatty acid profile were evaluated. A total of 71 participants completed the trial. Both dietary interventions significantly ameliorated MetS and improved the participants' inflammatory status. CR significantly increased the total iron-binding capacity (TIBC) whereas CRF increased hepcidin levels in women aged >45 years. Furthermore, CRF significantly increased the n-6/n-3 and arachidonic acid/docosahexaenoic acid ratios. Both interventions improved the anthropometric and MetS characteristics, including body weight, blood glucose and triglyceride levels, and the score of the homeostasis model assessment of insulin resistance and quantitative insulin sensitivity check index. In conclusion, the 12-week dietary interventions improved the abnormal metabolic status of middle-aged obese women. CRF was demonstrated to be more effective in ameliorating postprandial glucose level and TIBC in women aged >45 years than in those aged ≤45 years.

  3. Iron deficiency anemia: diagnosis and management.

    2009-03-01

    Iron deficiency anemia (IDA) still remains universally problematic worldwide. The primary focus of this review is to critique articles published over the past 18 months that describe strategies for the diagnosis and management of this prevalent condition. The medical community continues to lack consensus when identifying the optimal approach for the diagnosis and management of IDA. Current diagnostic recommendations revolve around the validity and practicality of current biomarkers such as soluble transferrin-receptor concentrations and others, and cause-based diagnostics that potentially include endoscopy. Management of IDA is based on supplementation combined with effective etiological treatment. Advances in oral and parenteral low-molecular-weight iron preparations has expanded and improved treatment modalities for IDA. Since the introduction of low versus high-molecular-weight intravenous iron administration, there have been fewer serious adverse events associated with parenteral iron preparations. Best practice guidelines for diagnosing and managing IDA should include the design of an algorithm that is inclusive of multiple biomarkers and cause-based diagnostics, which will provide direction in managing IDA, and distinguish between IDA from the anemia of chronic disease.

  4. Iron, Oxidative Stress and Gestational Diabetes

    Full Text Available Both iron deficiency and hyperglycemia are highly prevalent globally for pregnant women. Iron supplementation is recommended during pregnancy to control iron deficiency. The purposes of the review are to assess the oxidative effects of iron supplementation and the potential relationship between iron nutrition and gestational diabetes. High doses of iron (~relative to 60 mg or more daily for adult humans can induce lipid peroxidation in vitro and in animal studies. Pharmaceutical doses of iron supplements (e.g., 10× RDA or more for oral supplements or direct iron supplementation via injection or addition to the cell culture medium for a short or long duration will induce DNA damage. Higher heme-iron intake or iron status measured by various biomarkers, especially serum ferritin, might contribute to greater risk of gestational diabetes, which may be mediated by iron oxidative stress though lipid oxidation and/or DNA damage. However, information is lacking about the effect of low dose iron supplementation (≤60 mg daily on lipid peroxidation, DNA damage and gestational diabetes. Randomized trials of low-dose iron supplementation (≤60 mg daily for pregnant women are warranted to test the relationship between iron oxidative stress and insulin resistance/gestational diabetes, especially for iron-replete women.

    Growth faltering and anaemia remain unacceptably high among infants and young children in Ethiopia. In this study, we investigated the relationships among Fe supplement use (ISU), Hb concentration and linear growth, hypothesising positive relationships between ISU and Hb, ISU and linear growth and Hb and linear growth. We used a nationally representative data of 2400 children aged 6-24 months from the Ethiopian Demographic and Health Survey (EDHS) 2011, conducted following a stratified, two-stage cluster sampling. We examined the links by Pearson's correlation, bivariate and multivariate linear regression analyses and reported adjusted estimates. We found that ISU was not significantly associated with either Hb (β=1·09; 95 % CI -2·73, 5·01, P=0·567) or linear growth (β=0·07; 95 % CI -0·06, 0·21, P=0·217). We found a positive, however, weak, correlation between Hb and linear growth (r 0·09; 95 % CI 0·06, 0·11, PHb predicted linear growth independent of a variety dietary and non-dietary factors (β=0·08; 95 % CI 0·04, 0·11, PHb; age, birth type, size at birth, sex, breast-feeding duration, dietary diversity and deworming were independently associated with linear growth, indicating that Hb and linear growth are multifactorial with both nutritional and non-nutritional factors implicated. Further studies, with better design and exposure assessment, are warranted on the relation of ISU with Hb or linear growth.

    Full Text Available Background: Anemia during pregnancy is one of the most common disorders in pregnant women in Indonesia. The Government has made efforts to overcome this problem, however, the rate of anemic mothers remains high. Rosella (Hibiscus Sabdariffa is considered able to increase the hemoglobin levels in pregnant mothers. Objective: To analyze the effect of Rosella flower extract (Hibiscus Sabdariffa on the increase of Hemoglobin level in pregnant women with anemia receiving Fe tablet. Methods: This study was a quasy experiment with pretest-posttest control group design conducted in November - December 2016 in the working area of Tlogosari Wetan Community Health Center. Forty-two participants were selected using accidental sampling, which 21 assigned in the experiment and control group. All samples were pregnant women in the second trimester suffering from anemia and receiving iron tablets. Hemoglobin levels were measured using hematology analyzer in laboratory. Independent t-test and paired t-test were used for data analysis. Results: Paired t-test obtained p-value 0.00 (<0.05, indicated that there was an increase of hemoglobin levels in both experiment and control group. The mean increase of hemoglobin levels in the control group was 0.61 gr and in the experiment group was 1.08. The hemoglobin levels in the experiment group were higher than the levels in the control group. Independent t-test obtained p-value 0.000 (<0.05 indicating that there was a significant difference of mean of hemoglobin levels between the control group and the treatment group. Conclusion: The consumption of rosella extract combined with Fe tablet showed a significant increase of hemoglobin levels compared with the consumption of Fe tablet alone. Therefore, it is suggested for midwife to use the result of this research as a evidence practice through counseling for pregnant mother about utilization of rosella extract that can increase hemoglobin level in pregnant woman with anemia.

  14. Protein Hydrolysates as Promoters of Non-Haem Iron Absorption

    2017-06-01

    Full Text Available Iron (Fe is an essential micronutrient for human growth and health. Organic iron is an excellent iron supplement due to its bioavailability. Both amino acids and peptides improve iron bioavailability and absorption and are therefore valuable components of iron supplements. This review focuses on protein hydrolysates as potential promoters of iron absorption. The ability of protein hydrolysates to chelate iron is thought to be a key attribute for the promotion of iron absorption. Iron-chelatable protein hydrolysates are categorized by their absorption forms: amino acids, di- and tri-peptides and polypeptides. Their structural characteristics, including their size and amino acid sequence, as well as the presence of special amino acids, influence their iron chelation abilities and bioavailabilities. Protein hydrolysates promote iron absorption by keeping iron soluble, reducing ferric iron to ferrous iron, and promoting transport across cell membranes into the gut. We also discuss the use and relative merits of protein hydrolysates as iron supplements.

    Pregnant women are particularly vulnerable to iron deficiency and related adverse pregnancy outcomes and, as such, are routinely recommended for iron supplementation. Emerging evidence from both animal and population-based studies, however, has raised potential concerns because significant associations have been observed between greater iron stores and disturbances in glucose metabolism, including increased risk of type 2 diabetes among nonpregnant individuals. Yet, the evidence is uncertain regarding the role of iron in the development of gestational diabetes mellitus (GDM), a common pregnancy complication which has short-term and long-term adverse health ramifications for both women and their children. In this review, we critically and systematically evaluate available data examining the risk of GDM associated with dietary iron, iron supplementation, and iron status as measured by blood concentrations of several indicators. We also discuss major methodologic concerns regarding the available epidemiologic studies on iron and GDM. © 2017 American Society for Nutrition.

  1. Iron deficiency and cognitive functions

    2014-11-01

    Full Text Available Ignacio Jáuregui-Lobera Department of Nutrition and Bromatology, Pablo de Olavide University, Seville, Spain Abstract: Micronutrient deficiencies, especially those related to iodine and iron, are linked to different cognitive impairments, as well as to potential long-term behavioral changes. Among the cognitive impairments caused by iron deficiency, those referring to attention span, intelligence, and sensory perception functions are mainly cited, as well as those associated with emotions and behavior, often directly related to the presence of iron deficiency anemia. In addition, iron deficiency without anemia may cause cognitive disturbances. At present, the prevalence of iron deficiency and iron deficiency anemia is 2%–6% among European children. Given the importance of iron deficiency relative to proper cognitive development and the alterations that can persist through adulthood as a result of this deficiency, the objective of this study was to review the current state of knowledge about this health problem. The relevance of iron deficiency and iron deficiency anemia, the distinction between the cognitive consequences of iron deficiency and those affecting specifically cognitive development, and the debate about the utility of iron supplements are the most relevant and controversial topics. Despite there being methodological differences among studies, there is some evidence that iron supplementation improves cognitive functions. Nevertheless, this must be confirmed by means of adequate follow-up studies among different groups. Keywords: iron deficiency, anemia, cognitive functions, supplementation

    During pregnancy, iron needs to increase substantially to support fetoplacental development and maternal adaptation to pregnancy. To meet these iron requirements, both dietary iron absorption and the mobilization of iron from stores increase, a mechanism that is in large part dependent on the iron-regulatory hormone hepcidin. In healthy human pregnancies, maternal hepcidin concentrations are suppressed in the second and third trimesters, thereby facilitating an increased supply of iron into the circulation. The mechanism of maternal hepcidin suppression in pregnancy is unknown, but hepcidin regulation by the known stimuli (i.e., iron, erythropoietic activity, and inflammation) appears to be preserved during pregnancy. Inappropriately increased maternal hepcidin during pregnancy can compromise the iron availability for placental transfer and impair the efficacy of iron supplementation. The role of fetal hepcidin in the regulation of placental iron transfer still remains to be characterized. This review summarizes the current understanding and addresses the gaps in knowledge about gestational changes in hematologic and iron variables and regulatory aspects of maternal, fetal, and placental iron homeostasis. © 2017 American Society for Nutrition.

    Maternal micronutrient deficiencies may adversely affect fetal and infant health, yet there is insufficient evidence of effects on these outcomes to guide antenatal micronutrient supplementation in South Asia. To assess effects of antenatal multiple micronutrient vs iron-folic acid supplementation on 6-month infant mortality and adverse birth outcomes. Cluster randomized, double-masked trial in Bangladesh, with pregnancy surveillance starting December 4, 2007, and recruitment on January 11, 2008. Six-month infant follow-up ended August 30, 2012. Surveillance included 127,282 women; 44,567 became pregnant and were included in the analysis and delivered 28,516 live-born infants. Median gestation at enrollment was 9 weeks (interquartile range, 7-12). Women were provided supplements containing 15 micronutrients or iron-folic acid alone, taken daily from early pregnancy to 12 weeks postpartum. The primary outcome was all-cause infant mortality through 6 months (180 days). Prespecified secondary outcomes in this analysis included stillbirth, preterm birth (birth weight (births) in the iron-folic acid group and 741 deaths (51.6 per 1000 live births) in the multiple micronutrient group (relative risk [RR], 0.95; 95% CI, 0.86-1.06). Multiple micronutrient supplementation resulted in a non-statistically significant reduction in stillbirths (43.1 vs 48.2 per 1000 births; RR, 0.89; 95% CI, 0.81-0.99; P = .02) and significant reductions in preterm births (18.6 vs 21.8 per 100 live births; RR, 0.85; 95% CI, 0.80-0.91; P birth weight (40.2 vs 45.7 per 100 live births; RR, 0.88; 95% CI, 0.85-0.91; P supplementation did not reduce all-cause infant mortality to age 6 months but resulted in a non-statistically significant reduction in stillbirths and significant reductions in preterm births and low birth weight. clinicaltrials.gov Identifier: NCT00860470.

  6. Iron deficiency in cancer patients

    Directory of Open Access Journals (Sweden)

    Flávio Augusto Naoum

    Full Text Available ABSTRACT Anemia is a frequent complication in cancer patients, both at diagnosis and during treatment, with a multifactorial etiology in most cases. Iron deficiency is among the most common causes of anemia in this setting and can develop in nearly half of patients with solid tumors and hematologic malignancies. Surprisingly, this fact is usually neglected by the attending physician in a way that proper and prompt investigation of the iron status is either not performed or postponed. In cancer patients, functional iron deficiency is the predominant mechanism, in which iron availability is reduced due to disease or the therapy-related inflammatory process. Hence, serum ferritin is not reliable in detecting iron deficiency in this setting, whereas transferrin saturation seems more appropriate for this purpose. Besides, lack of bioavailable iron can be further worsened by the use of erythropoiesis stimulating agents that increase iron utilization in the bone marrow. Iron deficiency can cause anemia or worsen pre-existing anemia, leading to a decline in performance status and adherence to treatment, with possible implications in clinical outcome. Due to its frequency and importance, treatment of this condition is already recommended in many specialty guidelines and should be performed preferably with intravenous iron. The evidences regarding the efficacy of this treatment are solid, with response gain when combined with erythropoiesis stimulating agents and significant increments in hemoglobin as monotherapy. Among intravenous iron formulations, slow release preparations present more favorable pharmacological characteristics and efficacy in cancer patients.

    A straight-run flock of 1-day-old Cobb 400 chicks (n = 432) was distributed into four treatment groups (9 replicate pens in each group, 12 birds in a pen) for a 38-day feeding trial evaluating the effects of a methionine chelate (Met-TM)- or a yeast proteinate (Yeast-TM)-based supplement of copper (Cu), iron (Fe), manganese (Mn) and zinc (Zn) on growth performance, bone criteria and some metabolic indices in commercial broiler chickens. The diets were either not supplemented with any trace elements at all (negative control, NC) or supplemented with an inorganic (sulphate) trace element premix (inorganic TM (ITM), 1 g/kg feed), the Met-TM (1 g/kg feed) and the Yeast-TM (0.5 g/kg feed). Body weight, feed conversion ratio and dressed meat yield at 38 days were better in the Yeast-TM-supplemented group as compared with the NC, ITM and Met-TM groups (p broilers with methionine chelates or yeast proteinate forms of Cu, Fe, Mn and Zn improved body weight and feed conversion ratio (FCR) and markedly reduced excretion of the said trace elements. The study revealed that it may be possible to improve broiler performance and reduce excretion of critical trace elements into the environment by complete replacement of inorganic trace minerals from their dietary regime and replacing the same with methionine chelate or yeast proteinate forms.

    Anemia in patients suffering from end-stage renal failure is currently treated with Erythropoiesis-Stimulating Agents (ESA). This treatment needs sufficient iron supplementation to avoid an inadequate dosage of ESA. Nowadays modern analytical instruments allow to accurately calculate the content of Hemoglobin (Hb) in reticulocytes (CHr), that can be used as a guide for prescribing patients with the appropriate amount of iron. Patients, undergoing hemodialysis, were retrospectively selected from the database and were divided in two groups: group A received intravenous (IV) iron and subcutaneously ESA, and their dosages were adjusted on the basis of the following parameters: Hb, Mean corpuscular haemoglobin (MCH), CHr with consequent MCH/CHr ratio and reticulocyte count determined by the ADVIA 120 Hematology System of Siemens; group B patients were administered IV iron and ESA monitoring iron storage, Hb and ferritin. The aforementioned parameters and the administered amount of iron and ESA were monitored at baseline, four and eight months from the begining of the study. For ESA supplementation, no difference was observed between the groups at the various observed times. Despite similar Hb levels, the patients of group A needed significant lower doses of IV iron (-57.8%) avoiding risks of organ toxicity and obtaining consequent cost saving of nearly 1 €/patient/month. The use of CHr and its related parameters allows the avoidance of overdosage of IV iron, which can potentially damage organs, and the reduction of health care direct and indirect costs.

    Full Text Available Pain is the most common complaint in emergency department and there are several methods for its control. Among them, pharmaceutical methods are the most effective. Although intravenous morphine has been the most common choice for several years, it has some adverse effects. There are many researches about intravenous acetaminophen as an analgesic agent and it appears that it has good analgesic effects for various types of pain. We searched some electronic resources for clinical trials comparing analgesic effects of intravenous acetaminophen vs. intravenous morphine for acute pain treatment in emergency setting.In two clinical trials, the analgesic effect of intravenous acetaminophen has been compared with intravenous morphine for renal colic. The results revealed no significant difference between analgesic effects of two medications. Another clinical trial revealed that intravenous acetaminophen has acceptable analgesic effects on the post-cesarean section pain when combined with other analgesic medications. One study revealed that administration of intravenous acetaminophen compared to placebo before hysterectomy decreased consumption of morphine via patient-controlled analgesia pump and decreased the side effects. Similarly, another study revealed that the infusion of intravenous acetaminophen vs. placebo after orthopedic surgery decreased the consumption of morphine after the surgery. A clinical trial revealed intravenous acetaminophen provided a level of analgesia comparable to intravenous morphine in isolated limb trauma, while causing less side effects than morphine.It appears that intravenous acetaminophen has good analgesic effects for visceral, traumatic and postoperative pains compare with intravenous morphine.

    Full Text Available Context: Demineralization of tooth by erosion is caused by frequent contact between the tooth surface and acids present in soft drinks. Aim: The present study objective was to evaluate the remineralization potential of casein-phosphopeptide-amorphous calcium phosphate (CPP-ACP paste, 1.23% acidulated phosphate fluoride (APF gel and iron supplement on dental erosion by soft drinks in human primary and permanent enamel using atomic force microscopy (AFM. Materials and Methods: Specimens were made from extracted 15 primary and 15 permanent teeth which were randomly divided into three treatment groups: CPP-ACP paste, APF gel and iron supplement. AFM was used for baseline readings followed by demineralization and remineralization cycle. Results and Statistics: Almost all group of samples showed remineralization that is a reduction in surface roughness which was higher with CPP-ACP paste. Statistical analysis was performed using by one-way ANOVA and Mann-Whitney U-test with P < 0.05. Conclusions: It can be concluded that the application of CPP-ACP paste is effective on preventing dental erosion from soft drinks.

    Limited knowledge exists on sustained adherence to small-quantity lipid-based nutrient supplements for pregnant and lactating women (LNS-PL) and how this compares with that of other prenatal supplements. To address these gaps, a random subsample of women (n = 360) during pregnancy, early (6- to 12-week post-partum) and late (12- to 24-week post-partum) lactation, from an ongoing effectiveness trial in Bangladesh, was selected for in-home interviews about LNS-PL or iron/folic acid (IFA) use and preferences. Prevalence of high adherence (≥70% of the recommendation) based on self-reported supplement consumption was 67%, 68% and 81% among LNS-PL recipients during pregnancy, early and late lactation, and was 87% and 71% among IFA recipients during pregnancy and early lactation, respectively (P = 0.044). Programmatic factors (e.g. distribution and visits by programme staff) were consistently statistically significantly associated with reported high adherence. Among LNS-PL recipients, high overall supplement acceptability score [odds ratio (OR): 8.62; 95% confidence interval (CI) 3.53, 20.83] and use of reminder techniques (OR: 4.41; 95%CI 1.65, 11.76) were positively associated, and reported vomiting at enrollment was negatively associated (OR: 0.34; 95%CI 0.14, 0.80), with reported high adherence. Selected women (n = 16) and key informants (n = 18) participated in in-depth interviews about perceptions and acceptability of LNS-PL. Women perceived benefits of taking LNS-PL, but some faced barriers to consumption including aversion to odour and taste during pregnancy, forgetfulness and disruptions in supply. To achieve high adherence, results from this study suggest that maternal supplementation programmes should focus on programmatic barriers and consider incorporating reminder techniques. Organoleptic acceptability of LNS-PL, particularly during pregnancy, may also need to be addressed. © 2016 John Wiley & Sons Ltd.

Iron deficiency (ID may be caused by several diseases, even by physiological situations that increase requirements for this mineral. One of its possible causes is a poor dietary iron intake, which is infrequent in developed countries, but quite common in developing areas. In these countries, dietary ID is highly prevalent and comprises a real public health problem and a challenge for health authorities. ID, with or without anemia, can cause important symptoms that are not only physical, but can also include a decreased intellectual performance. All this, together with a high prevalence, can even have negative implications for a community’s economic and social development. Treatment consists of iron supplements. Prevention of ID obviously lies in increasing the dietary intake of iron, which can be difficult in developing countries. In these regions, foods with greater iron content are scarce, and attempts are made to compensate this by fortifying staple foods with iron. The effectiveness of this strategy is endorsed by multiple studies. On the other hand, in developed countries, ID with or without anemia is nearly always associated with diseases that trigger a negative balance between iron absorption and loss. Its management will be based on the treatment of underlying diseases, as well as on oral iron supplements, although these latter are limited by their tolerance and low potency, which on occasions may compel a change to intravenous administration. Iron deficiency has a series of

    Concerns have been raised about the benefits of Fe-containing supplements on infant birth weight among women with normal/high Hb levels at baseline. Thus far, no clinical trials have examined whether the effects of prenatal Fe-containing supplements on birth weight vary by maternal Hb levels. We compared the effects of Fe-folic acid (IFA) or multiple micronutrients (MMN) with folic acid (FA) supplements on birth weight among pregnant women with mild/no anaemia or high Hb levels. A double-blind randomised controlled trial was conducted in 2006-2009. In total, 18 775 pregnant women with mild/no anaemia (145 g/l) baseline Hb levels, IFA and MMN supplements increased birth weight by 91·44 (95% CI 3·37, 179·51) g and 107·63 (95% CI 21·98, 193·28) g (PHb concentration. In conclusion, the effects of Fe-containing supplements on birth weight depended on baseline Hb concentrations. The Fe-containing supplements improved birth weight in women with very high Hb levels before 20 weeks of gestation.

    Indications for direct visualization of the bile ducts include bile duct dilatation demonstrated by ultrasound or computed tomography (CT) scanning, where the cause of the bile duct dilatation is uncertain or where the anatomy of bile duct obstruction needs further clarification. Another indication is right upper quadrant pain, particularly in a post-cholecystectomy patient, where choledocholithiasis is suspected. A possible new indication is pre-operative evaluation prior to laparoscopic cholecystectomy. The bile ducts are usually studied by endoscopic retrograde cholangiopancreatography (ERCP), or, less commonly, trans-hepatic cholangiography. The old technique of intravenous cholangiography has fallen into disrepute because of inconsistent bile-duct opacification. The advent of spiral CT scanning has renewed interest in intravenous cholangiography. The CT technique is very sensitive to the contrast agent in the bile ducts, and angiographic and three-dimensional reconstructions of the biliary tree can readily be obtained using the CT intravenous cholangiogram technique (CT IVC). Seven patients have been studied using this CT IVC technique, between February 1995 and June 1996, and are the subject of the present report. Eight further studies have since been performed. The results suggest that CT IVC could replace ERCP as the primary means of direct cholangiography, where pancreatic duct visualization is not required. (authors)

    2013-06-01

    Full Text Available Neil D Goldberg Emeritus Chief of Gastroenterology, University of Maryland St. Joseph Medical Center, Towson, MD, USA Abstract: Iron deficiency anemia is the most common form of anemia worldwide, caused by poor iron intake, chronic blood loss, or impaired absorption. Patients with inflammatory bowel disease (IBD are increasingly likely to have iron deficiency anemia, with an estimated prevalence of 36%–76%. Detection of iron deficiency is problematic as outward signs and symptoms are not always present. Iron deficiency can have a significant impact on a patient's quality of life, necessitating prompt management and treatment. Effective treatment includes identifying and treating the underlying cause and initiating iron replacement therapy with either oral or intravenous iron. Numerous formulations for oral iron are available, with ferrous fumarate, sulfate, and gluconate being the most commonly prescribed. Available intravenous formulations include iron dextran, iron sucrose, ferric gluconate, and ferumoxytol. Low-molecular weight iron dextran and iron sucrose have been shown to be safe, efficacious, and effective in a host of gastrointestinal disorders. Ferumoxytol is the newest US Food and Drug Administration-approved intravenous iron therapy, indicated for iron deficiency anemia in adults with chronic kidney disease. Ferumoxytol is also being investigated in Phase 3 studies for the treatment of iron deficiency anemia in patients without chronic kidney disease, including subgroups with IBD. A review of the efficacy and safety of iron replacement in IBD, therapeutic considerations, and recommendations for the practicing gastroenterologist are presented.

The nutritional status was evaluated by comparing z scores for weight/age, length/age and weight/length based on the World Health Organization (2006 references. Morbidity information was collected during monthly visits. RESULTS: The groups showed similar nutritional status before supplementation. There were no differences in daily nutrient intake among groups. During the study, weight and length gain, and increments in anthropometric indices did not differ statistically among supplemented groups either. The occurrence and duration of morbidity episodes did not differ statistically among groups. In general, improvements were observed in both weight/age and weight/length indices in the population under study, whereas length/age showed no differences before and after supplementation. CONCLUSION: Different prophylactic iron doses had no different effects on the growth and nutritional status of non-anemic infants.

    Systemic lidocaine used in continuous infusion during the peri-operative period has analgesic, anti-hyperalgesic, as well as anti-inflammatory properties. This makes it capable of reducing the use of opioids and inhalational anaesthetics, and the early return of bowel function, and patient hospital stay. The aim of this narrative review was to highlight the pharmacology and indications for clinical application, along with new and interesting research areas. The clinical applications of peri-operative lidocaine infusion have been reviewed in several recent systematic reviews and meta-analyses in patients undergoing open and laparoscopic abdominal procedures, ambulatory procedures, and other types of surgery. Peri-operative lidocaine infusion may be a useful analgesic adjunct in enhanced recovery protocols. Potential benefits of intravenous lidocaine in chronic post-surgical pain, post-operative cognitive dysfunction, and cancer recurrence are under investigation. Due to its immunomodulation properties over surgical stress, current evidence suggests that intravenous lidocaine could be used in the context of multimodal analgesia.

    Background: Maternal health and nutrition play a crucial role in early child growth and development. However, little is known about the benefits of preconception micronutrient interventions beyond the role of folic acid (FA) and neural tube defects. Objective: We evaluated the impact of weekly preconception multiple micronutrient (MM) or iron and folic acid (IFA) supplementation on child growth and development through the age of 2 y compared with FA alone. Methods: We followed 1599 offspring born to women who participated in a randomized controlled trial of preconception supplementation in Vietnam. Women received weekly supplements that contained either 2800 μg FA, 60 mg Fe and 2800 μg FA, or 15 MMs including IFA, from baseline until conception followed by daily prenatal IFA supplements until delivery. Child anthropometry was measured at birth and at 3, 6, 12, 18, and 24 mo. Child development was measured with the use of the Bayley Scales for Infant Development III at 24 mo. Results: The groups were similar for baseline maternal and offspring birth characteristics. At 24 mo of age, the offspring in the IFA group had significantly higher length-for-age z scores (LAZs) (0.14; 95% CI: 0.03, 0.26), reduced risk of being stunted (0.87; 95% CI: 0.76, 0.99), and smaller yearly decline in LAZs (0.10; 95% CI: 0.04, 0.15) than the offspring in the FA group. Similar trends were found for the offspring in the MM group compared with the FA group for LAZs (0.10; 95% CI: -0.02, 0.22) and the risk of being stunted (0.88; 95% CI: 0.77, 1.01). Offspring in the IFA group had improved motor development ( P = 0.03), especially fine motor development (0.41; 95% CI: 0.05, 0.77), at the age of 24 mo, but there were no differences for measures of cognition or language. Conclusions: Preconception supplementation with IFA improved linear growth and fine motor development at 2 y of age compared with FA. Future studies should examine whether these effects persist and improve child health and

    Iron deficiency is estimated to impact more than 1.6 billion individuals worldwide, affecting child, maternal, and perinatal mortality. Iron supplementation, fortification, and dietary diversification are strategies to reduce the prevalence of iron deficiency. However, there are relatively few studies demonstrating the effectiveness of iron-fortified wheat flour as an intervention. To assess the relationship between average monthly per capita household consumption of iron-fortified wheat flour and iron deficiency among women of childbearing age in Oman. Data were obtained from the National Micronutrient Status and Fortified Food Coverage Survey, 2004. Iron deficiency status was compared between women living in households with a monthly per capita consumption of iron-fortified wheat flour of 1 kg or more and women living in households with a monthly per capita consumption of iron-fortified wheat flour of less than 1 kg. The analyses excluded women with elevated or unknown levels of C-reactive protein and controlled for characteristics of the women and household demographics. Consumption of iron-fortified wheat flour was associated with a lower prevalence of iron deficiency among women in our sample (adjusted odds ratio, 0.60), after controlling for age, employment status, marital status, intake of iron or multivitamin supplements, self-reported presence of a blood disorder, household income, educational level of head of household, and family size. These results suggest that women in our study living in households with a greater consumption of iron-fortified wheat flour have a lower prevalence of iron deficiency; however, additional study is needed.

  13. Meeting iron needs for infants and children.

    Iron deficiency early in life is associated with impaired neurological development. This study reviews the latest research on how to best meet iron requirements in infants and children. There is concurrent evidence that delayed cord clamping is well tolerated and improves infant iron stores. Iron supplements or enriched complementary foods starting before 6 months of life do not reduce iron deficiency prevalence in low-risk populations. However, for low birth weight infants, iron supplements before 6 months of life have long-term benefits. Iron deficiency anaemia (IDA) during the second half year of life is rare in countries with high compliance to iron-rich complementary foods, but remains a major problem globally. In high-risk populations, iron supplementation reduces IDA and possibly improves growth. However, increased risk of infections is a concern and optimal preventive strategies have not yet been determined. Finally, there is concurrent evidence that iron supplementation of anaemic school-aged children reduces IDA and possibly improves neuropsychological outcomes. Interventions for prevention of iron deficiency should be prioritized in risk groups. However, the unclear long-term benefits and possible risk of adverse effects, particularly increased infections in developing countries, prompt further large-scale, double-blinded trials.

    Hoorn, Ewout J

    2017-08-01

    The topic of intravenous (IV) fluids may be regarded as "reverse nephrology", because nephrologists usually treat to remove fluids rather than to infuse them. However, because nephrology is deeply rooted in fluid, electrolyte, and acid-base balance, IV fluids belong in the realm of our specialty. The field of IV fluid therapy is in motion due to the increasing use of balanced crystalloids, partly fueled by the advent of new solutions. This review aims to capture these recent developments by critically evaluating the current evidence base. It will review both indications and complications of IV fluid therapy, including the characteristics of the currently available solutions. It will also cover the use of IV fluids in specific settings such as kidney transplantation and pediatrics. Finally, this review will address the pathogenesis of saline-induced hyperchloremic acidosis, its potential effect on outcomes, and the question if this should lead to a definitive switch to balanced solutions.

    The present study was performed to compare the clinical value of urography and ultrasonography in a non-selected group of patients referred for urography to a university hospital. The conslusions and clinical implications of the study are as follows: Intravenous urography remains the cornerstone imaging examination in the evaluation of ureteral calculi. Ultrasonography is a valuable adjunct in cases of non- visualization of the kidneys, in distal obstruction and known contrast media allergy. When women with recurrent urinary tract infection are referred for imaging of the urinary tract, ultrasonography should be used. Ultrasonography should replace urography for screening of non-acute hydronephrosis like in female genital cancer and benign prostate hyperplasia. There is good correlation between urography and ultrasonography in assessing the degree of hydronephrosis. However, more researh on the relationship between hydronephrosis and obstruction is necessary. Ultrasonography should be used as the only imaging method of the upper urinary tract in patients with microscopic hematuria. In patients less than 50 years with macroscopic hematuria, ultrasonography should be used as the only imaging of the upper urinary tract, and an examination of the urinary bladder should be included. In patients over 50 years, urography supplied with ultrasonography should be used, but more research is necessary on the subject of imaging method and age. 158 refs

    The similarities between swine and humans in physiological and genomic patterns, and the great correlation in size and anatomy, make pigs extremely useful in preclinical studies. New-born piglets can represent a model for congenital and genetic diseases in new-born children. It is known that piglets may have significant differences in clinicopathological results compared to adult pigs. Therefore, adult laboratory reference intervals cannot be applied to piglets. The aim of this study was to compare haematological and chemical variables in piglets of two ages and determinate age-related reference intervals for commercial hybrid young pigs. Blood samples were collected under general anaesthesia from 130 animals divided into five- (P5) and 30- (P30) day-old piglets. Only P30 animals were treated with parenteral iron after birth. Samples were analysed using automated haematology (ADVIA 2120) and chemistry analysers, and age-related reference intervals were calculated. Significant higher values of RBC, Hb and HCT were observed in P30 animals when compared to P5, with an opposite trend for MCV. These results were associated with a reduction of the RBC regeneration process and the thrombopoietic response. The TSAT and TIBC were significantly higher in P30 compared to P5; however, piglets remained iron deficient compared to adult reference intervals reported previously. In conclusion, this paper emphasises the high variability occurring in clinicopathological variables between new-born and 30-day-old pigs, and between piglets and adult pigs. This study provides valuable reference data for piglets at precise ages and could be used in the future as historical control improving the Reduction in animal experiments, as suggested by the 3Rs principle.

    2012-01-01

    Full Text Available Background: Iron deficiency anemia (IDA is the most common medical problem in pregnancy. Parenteral iron is a useful treatment, although iron dextran use decreased due to anaphylaxis. Iron sucrose is a newer agent that has overcome the shortcomings of iron dextran. Objective: The aim of this study was to compare the efficacy and tolerance of intravenous iron sucrose (IVIS therapy with oral iron (OI therapy in pregnant women with IDA and to study the factors influencing treatment. Materials and Methods: This prospective, randomized clinical trial included pregnant women between 14 and 36 weeks with established IDA who were treated with IVIS or OI (ferrous fumarate. All patients were monitored for laboratory response and adverse effects. Independent sample-t test, Chi square test and ANOVA were used for statistical analysis. P < 0.05 was considered significant. Results: Although hemoglobin increased in both the groups, increase in the reticulocyte count and percentage increase in hemoglobin was significantly higher in the IVIS group than in the OI group (23.62% vs. 14.11%. Serum ferritin was significantly higher in the IVIS group than in the OI group (P = 0.000. The IVIS group had no major side-effects. Compliance was good with OI, although 23% had gastrointestinal side-effects. Patient weight, gestation at diagnosis, initial hemoglobin and ferritin levels did not influence the response to treatment. Conclusion: IVIS is safe and effective in the treatment of IDA during pregnancy. Iron stores increased better with IVIS compared with OI.

    Full Text Available Intravenous iron therapy is a useful treatment for the rapid correction of iron deficiency anaemia and can be used to avoid or reduce the requirement for allogeneic blood transfusion. Several intravenous iron preparations are available commercially which differ in cost, mode of administration and side effect profile. There are few data directly comparing the efficacy of these preparations. In this retrospective single-centre study, we present the results from two hundred and eight patients treated using three different iron preparations (iron dextran, iron sucrose and ferric carboxymaltose and compare the effect on haemoglobin levels and other measures of iron deficiency six weeks after treatment. Within the limitations of our study design, we show a statistically and clinically significant difference in efficacy between these preparations.

    Patients have to discontinue the use of oral iron therapy due to the development of side effects and lack of long-term adherence to medication for iron deficiency anemia. This study aimed to evaluate the therapeutic effectiveness, safety, and cost of intravenous iron sucrose therapy. The computerized database and medical records of 453 patients diagnosed with iron deficiency anemia who received intravenous iron sucrose therapy for iron deficiency anemia between 2004 and 2008 were reviewed. The improvement of hematologic parameters and cost of therapy were evaluated 4 weeks after therapy. 453 patients (443 females, 10 males; age: 44.2 +/- 12.3 years) received iron sucrose therapy. Mean hemoglobin, hematocrit, and mean corpuscular volume values were 8.2 +/- 1.4 g/dL, 26.9 +/- 3.8%, and 66.1 +/- 7.8 fL, respectively, before therapy and 11.5 +/- 1.0 g/dL, 35.8 +/- 2.5%, 76.5 +/- 6.1 fL, respectively, after therapy (P 50%). The mean cost of therapy was 143.07 +/- 29.13 US dollars. The therapy was well tolerated. Although the cost of intravenous iron sucrose therapy may seem high, a lack of adherence to therapy and side effects including gastrointestinal irritation during oral iron therapy were not experienced during intravenous therapy.

    The present study aims to investigate whether a daily intake of heme iron enriched peptide obtained from bovine hemoglobin is effective in alleviating iron deficiency anemia (IDA). Wistar rats were randomly divided into six groups: a control group, an anemic group not treated, and anemic groups treated with FeSO4 or with the heme iron enriched peptide at low, moderate or high doses. The rats in the anemic groups were fed on a low-iron diet to establish the iron deficiency anemia model. After the model had been established, different doses of heme iron enriched peptide were given to the rats once a day via intragastric administration. After the iron supplement administration, it was observed that heme iron enriched peptide had effective restorative action returning the hemoglobin, red blood cells, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin concentration and serum iron in IDA animals to normal values or better. In addition, compared with FeSO4, higher Fe bioavailability and fewer side effects were observed. The rats in the moderate dose group had the highest apparent Fe absorption. Moreover, in vivo antioxidant activity was also observed, enhancing the activities of antioxidant enzymes and reduced malondialdehyde levels in IDA rats. Furthermore, the heme iron enriched peptide also exhibited strong in vitro antioxidant activities. In conclusion, heme iron enriched peptide significantly alleviated iron deficiency anemia, and exhibited strong in vitro and in vivo antioxidant activities. This suggests that heme iron enriched peptide might be exploited as a safe, efficient new iron supplement.

    Use of performance-enhancing supplements occurs at all levels of sports, from professional athletes to junior high school students. Although some supplements do enhance athletic performance, many have no proven benefits and have serious adverse effects. Anabolic steroids and ephedrine have life-threatening adverse effects and are prohibited by the International Olympic Committee and the National Collegiate Athletic Association for use in competition. Blood transfusions, androstenedione, and dehydroepiandrosterone are also prohibited in competition. Caffeine, creatine, and sodium bicarbonate have been shown to enhance performance in certain contexts and have few adverse effects. No performance benefit has been shown with amino acids, beta-hydroxy-beta-methylbutyrate, chromium, human growth hormone, and iron. Carbohydrate-electrolyte beverages have no serious adverse effects and can aid performance when used for fluid replacement. Given the widespread use of performance-enhancing supplements, physicians should be prepared to counsel athletes of all ages about their effectiveness, safety, and legality.

    Iron derivatives from casein hydrolysate (Fe+3-peptide complex, are potential iron sources for biological applications. This study was conducted to evaluate rat liver and spleen iron deposition when administered Fe+3- peptide complex or iron sulfate, which was delivered via gavage for 28 days. Seventy rats (Hb 120g/L, divided into 7 groups (n=10, received a standard commercial diet containing 50 mg Fe/kg, supplemented by gastric gavage with daily doses (10, 30 and 60 mg Fe/kg body weight of iron peptide complex or iron sulfate for 4 weeks. The control group received Milli-Q water. Iron deposition in liver and spleen was determined qualitatively by histochemistry and quantitatively by atomic absorption spectrometry; lipid peroxidation was evaluated by the determination of thiobarbituric reactive substances. Iron deposition in liver was significantly reduced in groups supplemented with iron peptide complex when compared with the iron sulfate-supplemented groups (30 and 60 mg Fe/kg. A significant reduction of iron deposition in spleen was also shown in groups supplemented with iron-peptide complex (10 and 30 mg Fe/kg compared with iron sulfate, and 60 mg Fe/ kg, the levels of iron deposition were lower than in the control group. The results suggest that iron absorption could be better controlled when supplied as iron-peptide complex rather than of iron sulfate.

    Lobular capillary hemangioma is a vascular neoplasm that commonly occurs as a cutaneous tumor. When it involves the skin and mucosal surfaces, ulceration and suppuration may occur, hence the classic term of pyogenic granuloma. Intravenous pyogenic granuloma is a rare solitary form of lobular capillary hemangioma that usually occurs in the veins of the neck and upper extremities. We report the ultrasonographic and magnetic resonance imaging findings of a pyogenic intravenous granuloma localized in the right cephalic vein. The imaging and pathological findings and the differential diagnoses are discussed. (orig.)

    We experienced a case of stump pain relieved by continuous intravenous ketamine infusion therapy. A 59-year-old male had his left first through fourth toes amputated because a giant iron plate at work fell on his left foot fifteen years ago. Thereafter he had refractory spontaneous burning pain and night pain on his stump. On examination, we found his left foot skin hard, lustrous, and with sweating disturbance, allodynia and hyperpathia. As intravenous administrations of ketamine 10 mg and thiamylal 50 mg were positive as a drug challenge test, we performed intravenous ketamine infusion at 1 mg.kg-1.hr-1 for 1 hour and a half. After this treatment, his visual analogue scale (VAS) improved dramatically to 0 mm, and night pain, allodynia and hyperpathia disappeared for three days. Thereafter stump pain was relieved to the level of VAS 20 mm. Therefore we diagnosed his stump pain as central pain of neuropathic origin. We suspect that continuous intravenous infusion of ketamine, a noncompetitive blocker of N-methyl-D-aspartic acid receptor, might be an effective and useful alternative treatment in a patient with refractory stump pain.

  11. Iron, lead, and cobalt absorption: similarities and dissimilarities

    Using isolated intestinal segments in rats, the absorption of iron, lead, and cobalt was increased in iron deficiency and decreased in iron loading. Similarly, the absorption of these metals was decreased in transfusional erythocytosis, after intravenous iron injection and after parenteral endotoxin injection. Acute bleeding or abbreviated intervals of dietary iron deprivation resulted in increased iron absorption from isolated intestinal segments and in intact animals, while the absorption of lead and cobalt was unaffected. These results suggest that the specificity of the mucosal metal absorptive mechanism is either selectively enhanced for iron absorption by phlebotomy or brief periods of dietary iron deprivation, or that two or more mucosal pathways for iron absorption may exist

    Heart failure is an important community health problem. Prevalence and incidence of heart failure have continued to rise over the years. Despite recent advances in heart failure therapy, prognosis is still poor, rehospitalization rate is very high, and quality of life is worse. Co-morbidities in heart failure have negative impact on clinical course of the disease, further impair prognosis, and add difficulties to treatment of clinical picture. Therefore, successful management of co-morbidities is strongly recommended in addition to conventional therapy for heart failure. One of the most common co-morbidities in heart failure is presence of iron deficiency and anemia. Current evidence suggests that iron deficiency and anemia are more prevalent in patients with heart failure and reduced ejection fraction, as well as those with heart failure and preserved ejection fraction. Moreover, iron deficiency and anemia are referred to as independent predictors for poor prognosis in heart failure. There is strong relationship between iron deficiency or anemia and severity of clinical status of heart failure. Over the last two decades, many clinical investigations have been conducted on clinical effectiveness of treatment of iron deficiency or anemia with oral iron, intravenous iron, and erythropoietin therapies. Studies with oral iron and erythropoietin therapies did not provide any clinical benefit and, in fact, these therapies have been shown to be associated with increase in adverse clinical outcomes. However, clinical trials in patients with iron deficiency in the presence or absence of anemia have demonstrated considerable clinical benefits of intravenous iron therapy, and based on these positive outcomes, iron deficiency has become target of therapy in management of heart failure. The present report assesses current approaches to iron deficiency and anemia in heart failure in light of recent evidence.

    Full Text Available Intravenous levodopa has been used in a multitude of research studies due to its more predictable pharmacokinetics compared to the oral form, which is used frequently as a treatment for Parkinson’s disease (PD. Levodopa is the precursor for dopamine, and intravenous dopamine would strongly affect vascular tone, but peripheral decarboxylase inhibitors are intended to block such effects. Pulse and blood pressure, with orthostatic changes, were recorded before and after intravenous levodopa or placebo—after oral carbidopa—in 13 adults with a chronic tic disorder and 16 tic-free adult control subjects. Levodopa caused no statistically or clinically significant changes in blood pressure or pulse. These data add to previous data that support the safety of i.v. levodopa when given with adequate peripheral inhibition of DOPA decarboxylase.

    Iron deficiency occurs frequently in pregnancy and can be diagnosed by serum ferritin-level measurement (threshold value iron-deficiency anemia is recommended in every pregnant women, and should be done by serum ferritin-level screening in the first trimester and regular hemoglobin checks at least once per trimester. In the case of iron deficiency with or without anaemia in pregnancy, oral iron therapy should be given as first-line treatment. In the case of severe iron-deficiency anemia, intolerance of oral iron, lack of response to oral iron, or in the case of a clinical need for rapid and efficient treatment of anaemia (e.g., advanced pregnancy), intravenous iron therapy should be administered. In the postpartum period, oral iron therapy should be administered for mild iron-deficiency anemia (haemorrhagic anemia), and intravenous iron therapy for moderately severe-to-severe anemia (Hb iron therapy in pregnancy or postpartum, iron-containing drugs which have been studied in well-controlled clinical trials in pregnancy and postpartum such as ferric carboxymaltose must be preferred for safety reasons. While anaphylactic reactions are extremely are with non-dextrane products, close surveillance during administration is recommended for all intravenous iron products.

    Many athletes use dietary supplements, with use more prevalent among those competing at the highest level. Supplements are often self-prescribed, and their use is likely to be based on an inadequate understanding of the issues at stake. Supplementation with essential micronutrients may be useful when a diagnosed deficiency cannot be promptly and effectively corrected with food-based dietary solutions. When used in high doses, some supplements may do more harm than good: Iron supplementation, for example, is potentially harmful. There is good evidence from laboratory studies and some evidence from field studies to support health or performance benefits from appropriate use of a few supplements. The available evidence from studies of aquatic sports is small and is often contradictory. Evidence from elite performers is almost entirely absent, but some athletes may benefit from informed use of creatine, caffeine, and buffering agents. Poor quality assurance in some parts of the dietary supplements industry raises concerns about the safety of some products. Some do not contain the active ingredients listed on the label, and some contain toxic substances, including prescription drugs, that can cause health problems. Some supplements contain compounds that will cause an athlete to fail a doping test. Supplement quality assurance programs can reduce, but not entirely eliminate, this risk.

  5. Burkholderia pseudomallei modulates host iron homeostasis to facilitate iron availability and intracellular survival.

    Full Text Available The control over iron homeostasis is critical in host-pathogen-interaction. Iron plays not only multiple roles for bacterial growth and pathogenicity, but also for modulation of innate immune responses. Hepcidin is a key regulator of host iron metabolism triggering degradation of the iron exporter ferroportin. Although iron overload in humans is known to increase susceptibility to Burkholderia pseudomallei, it is unclear how the pathogen competes with the host for the metal during infection. This study aimed to investigate whether B. pseudomallei, the causative agent of melioidosis, modulates iron balance and how regulation of host cell iron content affects intracellular bacterial proliferation.Upon infection of primary macrophages with B. pseudomallei, expression of ferroportin was downregulated resulting in higher iron availability within macrophages. Exogenous modification of iron export function by hepcidin or iron supplementation by ferric ammonium citrate led to increased intracellular iron pool stimulating B. pseudomallei growth, whereas the iron chelator deferoxamine reduced bacterial survival. Iron-loaded macrophages exhibited a lower expression of NADPH oxidase, iNOS, lipocalin 2, cytokines and activation of caspase-1. Infection of mice with the pathogen caused a diminished hepatic ferroportin expression, higher iron retention in the liver and lower iron levels in the serum (hypoferremia. In vivo administration of ferric ammonium citrate tended to promote the bacterial growth and inflammatory response, whereas limitation of iron availability significantly ameliorated bacterial clearance, attenuated serum cytokine levels and improved survival of infected mice.Our data indicate that modulation of the cellular iron balance is likely to be a strategy of B. pseudomallei to improve iron acquisition and to restrict antibacterial immune effector mechanisms and thereby to promote its intracellular growth. Moreover, we provide evidence that

    Anemia affects one-fourth of the world’s population, and iron deficiency is the predominant cause. Anemia is associated with chronic fatigue, impaired cognitive function, and diminished well-being. Patients with iron deficiency anemia of unknown etiology are frequently referred to a gastroenterologist because in the majority of cases the condition has a gastrointestinal origin. Proper management improves quality of life, alleviates the symptoms of iron deficiency, and reduces the need for blood transfusions. Treatment options include oral and intravenous iron therapy; however, the efficacy of oral iron is limited in certain gastrointestinal conditions, such as inflammatory bowel disease, celiac disease, and autoimmune gastritis. This article provides a critical summary of the diagnosis and treatment of iron deficiency anemia. In addition, it includes a management algorithm that can help the clinician determine which patients are in need of further gastrointestinal evaluation. This facilitates the identification and treatment of the underlying condition and avoids the unnecessary use of invasive methods and their associated risks. PMID:27099596

    Iron deficiency, with or without anemia, is extremely frequent worldwide, representing a major public health problem. Iron replacement therapy dates back to the seventeenth century, and has progressed relatively slowly until recently. Both oral and intravenous traditional iron formulations are known to be far from ideal, mainly because of tolerability and safety issues, respectively. At the beginning of this century, the discovery of hepcidin/ferroportin axis has represented a turning point in the knowledge of the pathophysiology of iron metabolism disorders, ushering a new era. In the meantime, advances in the pharmaceutical technologies are producing newer iron formulations aimed at minimizing the problems inherent with traditional approaches. The pharmacokinetic of oral and parenteral iron is substantially different, and diversities have become even clearer in light of the hepcidin master role in regulating systemic iron homeostasis. Here we review how iron therapy is changing because of such important advances in both pathophysiology and pharmacology.

    Full Text Available Paul StrossDepartment of Haematology, St Richard's Hospital, Chichester, United KingdomBackground: Hereditary hemorrhagic telangiectasia is an autosomal dominant disorder associated with frequent nose bleeds that can be troublesome and difficult to contain. A further manifestation is telangiectasia, which may develop in the upper and lower gastrointestinal tract. The associated blood loss can be chronic, resulting in iron deficiency anemia which, when severe, has historically been treated by blood transfusions. Further pulmonary, neurologic, and hepatic complications may appear in later life, and are well documented. Administering blood transfusions requires provision, storage, and serological testing to select suitable units. Recognition of the inherent potential risks of donated blood, the expense, and the concerns regarding blood supply, has resulted in a national policy for conservation and appropriate use of blood. For an individual patient, there may be development of alloantibodies which complicates future cross-matching for transfusions.Case report: SG is a 66-year-old Caucasian woman who first presented to our hematology department in 2003, having just moved to the area. She had suffered with nose bleeds since her teenage years and presented with a low hemoglobin level and symptoms of iron deficiency anemia. Medical and nonmedical interventions failed to arrest the blood loss, which had not been massive or associated with hypovolemic shock. Pursuant to conserving blood supplies, and based on experience of patients with other causes of iron deficiency anemia, a regimen of high-dose iron supplementation was adopted. The aim was to sustain iron stores as a substrate for erythropoiesis and thereby achieve adequate hemoglobin levels whilst minimizing the need for blood transfusion.Discussion: This approach has maintained the patient's hemoglobin levels at 6.4–11.6 g/dL over a period of 9 years.

    Iron deficiency anemia is the most common nutritional deficiency in humans. Not all dietary ingested iron, heme or nonheme, will be available to absorption and negative imbalance between iron requirements and absorption leads to iron deficiency and/or anemia. The recommended iron values usually are based on the genetic and on diet iron-bioavailability, which can be considered as the principal factor that change among the cultures and influences the distinct levels of recommendation among countries. Dietary changes present practical limitations due to be difficult to change food habits. The iron food fortification is considered more cost effective and economically more attractive than iron supplementation. There are many iron compounds available to be used in iron fortification. Cereals represent a target food group to iron fortification programs due to high consumption and the in vitro studies can be useful to estimate the relative iron bioavailability in large number of products in short time and with a low cost. Wheat flour baked into bread or not was the main product tested in in vitro bioavailability studies and ferrous sulfate was the principal iron compound used in the fortification studies. However, iron bioavailability from ferrous sulfate is lower than from other compounds, such FeNaEDTA or ferric pyrophosphate. The variables level of fortification, storage, level of extraction, baking and also the association or not with other chemical compound seems to influence the results obtained.

    Dietary iron supplementation is associated with increased appetite. Here, we investigated the effect of iron on the hormone leptin, which regulates food intake and energy homeostasis. Serum ferritin was negatively associated with serum leptin in a cohort of patients with metabolic syndrome. Moreover, the same inverse correlation was observed in mice fed a high-iron diet. Adipocyte-specific loss of the iron exporter ferroportin resulted in iron loading and decreased leptin, while decreased levels of hepcidin in a murine hereditary hemochromatosis (HH) model increased adipocyte ferroportin expression, decreased adipocyte iron, and increased leptin. Treatment of 3T3-L1 adipocytes with iron decreased leptin mRNA in a dose-dependent manner. We found that iron negatively regulates leptin transcription via cAMP-responsive element binding protein activation (CREB activation) and identified 2 potential CREB-binding sites in the mouse leptin promoter region. Mutation of both sites completely blocked the effect of iron on promoter activity. ChIP analysis revealed that binding of phosphorylated CREB is enriched at these two sites in iron-treated 3T3-L1 adipocytes compared with untreated cells. Consistent with the changes in leptin, dietary iron content was also directly related to food intake, independently of weight. These findings indicate that levels of dietary iron play an important role in regulation of appetite and metabolism through CREB-dependent modulation of leptin expression.

Two types of biologically related iron salts, namely ferrous citrate and glycinate were prepared as potential iron supplements. The quantitative analysis of iron in these samples was determined using two techniques, atomic absorption spectrophotometery and uv-visible spectroscopy. The amount of iron was found to be 0.52-0.60 mg in tablet and 0.805-0.840g/100 ml in the syrup respectively. The percentage of Fe in the two ferrous citrate samples and ferrous glycinate sample were found to be 88.65%, 26.22% and 60.63% respectively. (Author)

    Full Text Available Intravenous sedation is effective to reduce fear and anxiety in dental treatment. It also has been used for behavior modification technique in dental patients with special needs. Midazolam and propofol are commonly used for intravenous sedation. Although there have been many researches on the effects of midazolam and propofol on vital function and the recovery profile, little is known about muscle power. This review discusses the effects of intravenous sedation using midazolam and propofol on both grip strength and bite force. During light propofol sedation, grip strength increases slightly and bite force increases in a dose-dependent manner. Grip strength decreases while bite force increases during light midazolam sedation, and also during light sedation using a combination of midazolam and propofol. Flumazenil did not antagonise the increase in bite force by midazolam. These results may suggest following possibilities; (1 Activation of peripheral benzodiazepine receptors located within the temporomandibular joint region and masticatory muscles may be the cause of increasing bite force. (2 Propofol limited the long-latency exteroceptive suppression (ES2 period during jaw-opening reflex. Thus, control of masticatory muscle contraction, which is thought to have a negative feedback effect on excessive bite force, may be depressed by propofol.

    iron deficiency anemia is a common and very relevant manifestation of inflammatory bowel disease (IBD). Although clinical practice guidelines have been published and updated on this subject, the management in the daily practice of this complication is far from optimal. to determine the actual management, needs and limitations of anemia in IBD by means of a survey of gastroenterology specialists. a self-administered telematic survey was carried out between April and May 2017 and was sent to SEPD members. The survey included four sections: participant demographics, monitoring, treatment and limitations/needs. a total of 122 evaluable surveys were received from all Spanish autonomous communities. Iron deficiency anemia is considered as a frequent manifestation of IBD and is monitored in all patients via the measurement of hemoglobin and ferritin. In the case of anemia, the survey respondents found it necessary to rule out the presence of IBD activity. However, only 14.8% prescribed intravenous iron when IBD was active. The required dose of intravenous iron is mainly calculated according to patient needs but only 33.1% of clinicians infused doses of 1 g or more. the "Gestiona Hierro EII" survey on the management of anemia in IBD demonstrated a high quality of care, even though some aspects need to be improved. These included the prescription of intravenous iron for patients with disease activity, the use of high-dose intravenous iron and the implementation of algorithms into clinical practice.

    The gastrointestinal absorption of iron was investigated in a number of multiparous women living under low socio-economic conditions which are known to lead commonly to iron deficiency. The percentage absorption was deduced by comparing the concentration of 55 Fe and/or 59 Fe in blood with the activity of the corresponding isotope(s) administered orally about two weeks earlier. It was confirmed or established that: (1) food or supplemental iron, if available at all, tends to be absorbed from the intestines as if present there in one of two alternative pools: heme and non-heme, (2) vitamin C substantially increases absorption of food or supplemental non-heme iron, (3) it is technically possible to use common salt or sugar as a carrier for supplemental iron and vitamin C, but practical difficulties of using such systems in a public health prophylactic programme are severe, and (4) tea, presumably because of its tannin content, inhibits absorption of accompanying iron

    In order to keep up the optimal iron status in chronic hemodialysis patients, it is important to know how much iron is lost due to hemodialysis. Residual blood associated with the hemodialysis procedure together with blood sampling inevitably causes the loss of iron in chronic hemodialysis patients. Recent advances in hemodialysis techniques might have reduced this complication. In this cross-sectional study, we directly measured total iron loss by hemodialysis. Two hundred thirty-nine patients who received chronic hemodialysis at Otowa Memorial Hospital were enrolled; 65.7% of patients were men, and mean age was 67 ± 6.4 years (mean ± SD) and 43.2% were diabetic. Residual blood in blood tubing set and dialyzer after rinse back with saline was collected and homogenized. The iron content including free, protein-bound and heme iron was measured using an atomic absorption spectrometry. The mean iron content in residual blood was 1,247.3 ± 796.2 µg (mean ± SD) and the median was 1,002 µg (95% CI 377.6-3,461.6 µg), indicating 160.8 mg (95% CI 58.9-540.0 mg) iron loss annually when hemodialysis was performed 156 times a year. Fifty milliliter whole blood for monthly blood test and another 2 ml of whole blood lost by paracentesis at every dialysis session contains 228.6 and 118.9 mg iron at 11 g/dl hemoglobin, respectively. Therefore, an annual total iron loss due to hemodialysis comes to 508.3 mg (95% CI 406.4-887.5 mg). Five hundred milligram of annual iron supplementation might be sufficient to maintain iron status in hemodialysis patients, which is less than the dose recommended as 1,000-2,000 mg a year. Further study will be required to verify this iron supplementation dosage with recent hemodialysis procedure. © 2016 S. Karger AG, Basel.

    Objective:To compare the efficacy and safety profile of total dose infusion of low molecular weight iron dextran with divided doses of intravenous iron sucrose for the treatment of iron deficiency anemia during pregnancy. Study Design: Randomized controlled trial. Place and Duration of Study: Shifa International Hospital, Islamabad, over a period of two years from January 2008 to December 2009. Methodology: Pregnant women at gestational age more than 12 weeks with the confirmed diagnosis of Iron Deficiency Anemia (IDA) were divided into two groups. In the group-A, intravenous iron sucrose was given in divided doses while in the group-B, total daily intake of Low Molecular Weight (LMW) of iron dextran was given. Post-infusion Hemoglobin (Hb) was checked at 4 weeks and at the time of delivery for both groups. Paired sample t-test is applied and comparison (in terms of rise in hemoglobin from pre to post) of both groups was not found to be significant. Results: In the group-A (iron sucrose group), mean pre-infusion Hb levels was 9.09 ± 0.83 gm/dl. Mean increase in Hemoglobin (Hb) was 10.75 ± 1.097 gm/dl after 4 weeks of infusion and 11.06 ± 0.866 gm/dl at delivery (p < 0.001). In group-B (iron dextran group) pre-infusion haemoglobin was 8.735 ± 0.956 gm/dl and the mean increase in hemoglobin was 10.613 ± 1.22 gm/dl at 4-week while mean increase of 10.859 ± 1.11 gm/dl at the time of delivery (p < 0.001). Conclusion: Both LMW iron dextran, as well as iron sucrose are equally effective in treatment of IDA during pregnancy, however, LMW iron dextran has the advantage of single visit treatment. (author)

    For the athlete training hard, nutritional supplements are often seen as promoting adaptations to training, allowing more consistent and intensive training by promoting recovery between training sessions, reducing interruptions to training because of illness or injury, and enhancing competitive performance. Surveys show that the prevalence of supplement use is widespread among sportsmen and women, but the use of few of these products is supported by a sound research base and some may even be harmful to the athlete. Special sports foods, including energy bars and sports drinks, have a real role to play, and some protein supplements and meal replacements may also be useful in some circumstances. Where there is a demonstrated deficiency of an essential nutrient, an increased intake from food or from supplementation may help, but many athletes ignore the need for caution in supplement use and take supplements in doses that are not necessary or may even be harmful. Some supplements do offer the prospect of improved performance; these include creatine, caffeine, bicarbonate and, perhaps, a very few others. There is no evidence that prohormones such as androstenedione are effective in enhancing muscle mass or strength, and these prohormones may result in negative health consequences, as well as positive drug tests. Contamination of supplements that may cause an athlete to fail a doping test is widespread.

  7. Iron deficiency in the tropics.

    Iron in food is classified as belonging to the haem pool, the nonhaem pool, and extraneous sources. Haem iron is derived from vegetable and animal sources with varying bioavailability. Hookworm infestation of the intestinal tract affects 450 million people in the tropics. Schistosoma mansoni caused blood loss in 7 Egyptian patients of 7.5- 25.9 ml/day which is equivalent to a daily loss of iron of .6-7.3 mg daily urinary loss of iron in 9 Egyptian patients. Trichuris trichiura infestation by whipworm is widespread in children with blood loss of 5 ml/day/worm. The etiology of anemia in children besides iron deficiency includes malaria, bacterial or viral infections, folate deficiency and sickle-cell disease. Severe infections cause profound iron-deficiency anemia in children in central American and Malaysia. Plasmodium falciparum malaria-induced anaemia in tropical Africa lowers the mean haemoglobin concentration in the population by 2 g/dI, causing profound anaemia in some. The increased risk of premature delivery, low birthweight, fetal abnormalities, and fetal death is directly related to the degree of maternal anemia. Perinatal mortality was reduced from 38 to 4% in treated anemic mothers. Mental performance was significantly lower in anemic school children and improved after they received iron. Supplements of iron, soy-protein, calcium, and vitamins given to villagers with widespread malnutrition, iron deficiency, and hookworm infestation in Colombia reduced enteric infections in children. Severe iron-deficiency anemia was treated in adults in northern Nigeria by daily in Ferastral 10 ml, which is equivalent to 500 mg of iron per day. Choloroquine, folic acid, rephenium hydroxynaphthoate, and tetrachlorethylene treat adults with severe iron deficiency from hookworm infestation in rural tropical Africa. Blood transfusion is indicated if the patient is dying of anaemia or is pregnant with a haemoglobin concentration 6 gm/dl. In South East Asia, mg per day

    Full Text Available Background Iron is an essential nutrient for normal growth and neurodevelopment of infants. Iron deficiency (ID remains the most common micronutrient deficiency worldwide. There are convincing data that ID is associated with negative effects on neurological and psychomotor development. Objectives In this review, we provide an overview of current knowledge of the importance of iron in normal term breast-fed infants with a focus on recommendations, metabolism, and iron requirements. Conclusions Health organizations around the world recommend the introduction of iron-rich foods or iron supplements for growing infants to prevent ID. However, there is no routine screening for ID in infancy. Multicenter trials with long-term follow-up are needed to investigate the association between iron fortification/supplementation and various health outcomes.

    As shown in previous studies vegetarians and especially vegans are at risk for iron deficiency. Our study evaluated the iron status of German female vegans. In this cross-sectional study, the dietary intakes of 75 vegan women were assessed by two 9-day food frequency questionnaires. The iron status was analyzed on the basis of blood parameters. Mean daily iron intake was higher than recommended by the German Nutrition Society. Still 42% of the female vegans or = 50 years (old women, OW). In all, 40% (tri-index model (TIM) 20%) of the YW and 12% (TIM 12%) of the OW were considered iron-deficient based on either serum ferritin levels of vegan diet should have their iron status monitored and should consider taking iron supplements in case of a marginal status.

    After all bariatric procedures, multivitamin supplements are uniformly prescribed to minimize eventual deficiencies. These supplements are usually maintained long time, even during the whole life after malabsorptive techniques, while these are maintained at least during 1 year after restrictive procedures. Given that sleeve gastrectomy does not alter intestinal absorption, the supplements are possibly unnecessary, once the patient can take an adequate diet. A prospective randomized study of patients undergoing a laparoscopic sleeve gastrectomy was performed. Patients were randomized into two groups: those patients receiving the multivitamin supplement (Multicentrum, Pfizer, 1 tablet/day) during 3 months (group 1) and those receiving the supplement during 12 months (group 2). Laboratory data were recorded: vitamins (D, B12 and folic acid) and oligoelements (calcium, iron, phosphorus, magnesium and zinc) at 3, 6 and 12 months after surgery. Eighty patients were included, 40 in each group. At 3 months, 7.5 % of the patients presented iron deficiency and 2.5 % ferritin one, similarly in both groups, that was corrected with specific extra iron supplements. At 6 months, one patient (2.5 %) in group 1 presented iron deficiency and one in group 2 vitamin D deficiency (NS). At 12 months, only one patient in group 2 presented vitamin D deficiency, treated with specific supplements. The maintenance of multivitamin supplements more than 3 months postoperatively seems to be of no benefit. It is preferable monitoring laboratory values and adding specific supplements when necessary.

  12. Calculating iron transport in nuclear systems

    The presence of high levels of iron in the final feedwater of nuclear plants is undesirable and can have a significant contribution to plant operations and maintenance (O and M) costs. A number of options are available to reduce the iron concentration, but tend to be expensive. Recently a method was developed to quantitatively determine the contribution of each iron source, such that reduction options can be quantitatively compared. The method is based on industry experience that the majority of iron has been released by flow-accelerated corrosion (FAC). FAC is one of the most predictable forms of corrosion and a well-developed predictive model has been developed and also encoded in the CHECWORKS. A combination of CHECWORKS and supplemental calculations have been used to model the iron transport in a number of US BWRs and PWRs. The iron generated by FAC in all the normally operating piping systems has been calculated using the results of CHECWORKS predictions and a special post processor. The post processor accounts for the differences between the maximum corrosion rate calculated by CHECWORKS and the average corrosion (iron generation) rate for a pipe-fitting or length of pipe. It also calculates the amount of iron generated within the fitting or pipe. Supplemental calculations have been used to determine the iron generation from the major, in-line components - high and low pressure turbines, moisture separators, feedwater heaters and the condenser. All of the iron generation rates for the equipment and piping were appropriately summed and iron concentrations estimated throughout the steam-feedwater system. Predicted iron concentrations have agreed well with plant measurements. The availability of specific iron generation rates allows plant management to make reasoned decisions about the countermeasures to deal with iron generation and transport. The countermeasures that have been examined to reduce the amount of iron transport include installing additional water

    Kaitha, Sindhu; Bashir, Muhammad; Ali, Tauseef

    2015-01-01

    Anemia is a common extraintestinal manifestation of inflammatory bowel disease (IBD) and is frequently overlooked as a complication. Patients with IBD are commonly found to have iron deficiency anemia (IDA) secondary to chronic blood loss, and impaired iron absorption due to tissue inflammation. Patients with iron deficiency may not always manifest with signs and symptoms; so, hemoglobin levels in patients with IBD must be regularly monitored for earlier detection of anemia. IDA in IBD is associated with poor quality of life, necessitating prompt diagnosis and appropriate treatment. IDA is often associated with inflammation in patients with IBD. Thus, commonly used laboratory parameters are inadequate to diagnose IDA, and newer iron indices, such as reticulocyte hemoglobin content or percentage of hypochromic red cells or zinc protoporphyrin, are required to differentiate IDA from anemia of chronic disease. Oral iron preparations are available and are used in patients with mild disease activity. These preparations are inexpensive and convenient, but can produce gastrointestinal side effects, such as abdominal pain and diarrhea, that limit their use and patient compliance. These preparations are partly absorbed due to inflammation. Non-absorbed iron can be toxic and worsen IBD disease activity. Although cost-effective intravenous iron formulations are widely available and have improved safety profiles, physicians are reluctant to use them. We present a review of the pathophysiologic mechanisms of IDA in IBD, improved diagnostic and therapeutic strategies, efficacy, and safety of iron replacement in IBD. PMID:26301120

    Iron deficiency (ID) has been identified as an important co-morbidity in patients with heart failure (HF). Intravenous iron therapy reduced symptoms and rehospitalizations of iron-deficient patients with HF in randomized trials. The present multicenter study investigated the "real-world" management of iron status in patients with HF. Consecutive patients with HF and ejection fraction ≤40% were recruited and analyzed from December 2010 to October 2015 by 11 centers in Germany and Switzerland. Of 1,484 patients with HF, iron status was determined in only 923 patients (62.2%), despite participation of the centers in a registry focusing on ID and despite guideline recommendation to determine iron status. In patients with determined iron status, a prevalence of 54.7% (505 patients) for ID was observed. Iron therapy was performed in only 8.5% of the iron-deficient patients with HF; 2.6% were treated with intravenous iron therapy. The patients with iron therapy were characterized by a high rate of symptomatic HF and anemia. In conclusion, despite strong evidence of beneficial effects of iron therapy on symptoms and rehospitalizations, diagnostic and therapeutic efforts on ID in HF are low in the actual clinical practice, and the awareness to diagnose and treat ID in HF should be strongly enforced.

    2013-01-01

    Creatine monohydrate is a dietary supplement that increases muscle performance in short-duration, high-intensity resistance exercises, which rely on the phosphocreatine shuttle for adenosine triphosphate. The effective dosing for creatine supplementation includes loading with 0.3 g·kg·d for 5 to 7 days, followed by maintenance dosing at 0.03 g·kg·d most commonly for 4 to 6 wk. However loading doses are not necessary to increase the intramuscular stores of creatine. Creatine monohydrate is the most studied; other forms such as creatine ethyl ester have not shown added benefits. Creatine is a relatively safe supplement with few adverse effects reported. The most common adverse effect is transient water retention in the early stages of supplementation. When combined with other supplements or taken at higher than recommended doses for several months, there have been cases of liver and renal complications with creatine. Further studies are needed to evaluate the remote and potential future adverse effects from prolonged creatine supplementation.

  3. Approaches for Reducing the Risk of Early-Life Iron Deficiency-Induced Brain Dysfunction in Children

    Directory of Open Access Journals (Sweden)

    Sarah E. Cusick

    2018-02-01

    Full Text Available Iron deficiency is the most common micronutrient deficiency in the world. Women of reproductive age and young children are particularly vulnerable. Iron deficiency in late prenatal and early postnatal periods can lead to long-term neurobehavioral deficits, despite iron treatment. This may occur because screening and treatment of iron deficiency in children is currently focused on detection of anemia and not neurodevelopment. Anemia is the end-stage state of iron deficiency. The brain becomes iron deficient before the onset of anemia due to prioritization of the available iron to the red blood cells (RBCs over other organs. Brain iron deficiency, independent of anemia, is responsible for the adverse neurological effects. Early diagnosis and treatment of impending brain dysfunction in the pre-anemic stage is necessary to prevent neurological deficits. The currently available hematological indices are not sensitive biomarkers of brain iron deficiency and dysfunction. Studies in non-human primate models suggest that serum proteomic and metabolomic analyses may be superior for this purpose. Maternal iron supplementation, delayed clamping or milking of the umbilical cord, and early iron supplementation improve the iron status of at-risk infants. Whether these strategies prevent iron deficiency-induced brain dysfunction has yet to be determined. The potential for oxidant stress, altered gastrointestinal microbiome and other adverse effects associated with iron supplementation cautions against indiscriminate iron supplementation of children in malaria-endemic regions and iron-sufficient populations.

Furthermore, they should be convenient for the patient and health-care professional, and cost effective for the health-care system. The intention behind the development of iron isomaltoside (Monofer® was to fulfill these requirements. Iron isomaltoside has been shown to be effective in treating iron deficiency anemia across multiple therapeutic patient groups and compared to placebo, IV iron sucrose, and oral iron. Iron isomaltoside consists of iron and a carbohydrate moiety where the iron is tightly bound in a matrix structure. It has a low immunogenic potential, a low potential to release labile iron, and does not appear to be associated with clinically significant hypophosphatemia. Due to the structure of iron isomaltoside, it can be administered in high doses with a maximum single dosage of 20 mg/kg body weight. Clinical trials and observational studies of iron isomaltoside show that it is an effective and well-tolerated treatment of anemia across different therapeutic areas with a favorable safety profile.Keywords: iron deficiency anemia, iron isomaltoside, high dose, iron treatment, hypophosphatemia, intact fibroblast growth factor 23

    2013-03-01

    Idiopathic pulmonary hemosiderosis (IPH), a subtype of diffuse alveolar hemorrhage is a rare condition, first described by Virchow in 1864. Historically, it manifests in children in the first decade of life with the combination of hemoptysis, iron deficiency anemia, and alveolar infiltrates on chest radiograph. More recently, diffuse alveolar hemorrhage has been classified by the absence or presence of pulmonary capillaritis (PC), the latter carrying a potential for a poorer outcome. While systemic corticosteroids remain the first line treatment option, other immune modulators have been trailed including hydroxychloroquine, azathioprine, 6-mercaptopurine, and cyclophosphamide with varying results. Our case demonstrates for the first time, the successful use of intravenous cyclophosphamide in the management of chronic idiopathic PC.

    Obesity is often associated with disorders of iron homeostasis; however, the underlying mechanisms are not fully understood. Hepcidin is a key regulator of iron metabolism and may be responsible for obesity-driven iron deficiency. Herein, we used an animal model of diet-induced obesity to study high-fat-diet-induced changes in iron homeostasis. C57BL/6 mice were fed a standard (SD) or high-fat diet (HFD) for 8 weeks, and in addition, half of the mice received high dietary iron (Fe+) for the last 2 weeks. Surprisingly, HFD led to systemic iron deficiency which was traced back to reduced duodenal iron absorption. The mRNA and protein expressions of the duodenal iron transporters Dmt1 and Tfr1 were significantly higher in HFD- than in SD-fed mice, indicating enterocyte iron deficiency, whereas the mRNA levels of the duodenal iron oxidoreductases Dcytb and hephaestin were lower in HFD-fed mice. Neither hepatic and adipose tissue nor serum hepcidin concentrations differed significantly between SD- and HFD-fed mice, whereas dietary iron supplementation resulted in increased hepatic hepcidin mRNA expression and serum hepcidin levels in SD as compared to HFD mice. Our study suggests that HFD results in iron deficiency which is neither due to intake of energy-dense nutrient poor food nor due to increased sequestration in the reticulo-endothelial system but is the consequence of diminished intestinal iron uptake. We found that impaired iron absorption is independent of hepcidin but rather results from reduced metal uptake into the mucosa and discordant oxidoreductases expressions despite enterocyte iron deficiency.

Results: The FCMS-treated group had significantly lower blood pressure, higher liver enzymes, increased proteinuria, and reduced creatinine clearance versus the FCM and control groups by day 29. Serum iron and transferrin saturation were significantly higher with FCMS versus FCM or controls. Iron deposition was altered in FCMS-treated animals, with decreased ferritin deposits and iron deposition outside the physiological storage compartments. Markers for lipid peroxidation and antioxidant-enzyme activity were significantly increased after FCMS administration versus FCM and controls, as were inflammatory markers. Conclusion: Results from this blinded nonclinical study demonstrated significant differences between the originator FCM and this FCMS.

    Compact flow-through optoelectronic detectors fabricated by pairing of light emitting diodes have been applied for development of economic flow analysis systems dedicated for iron ions determination. Three analytical methods with different chromogens selectively recognizing iron ions have been compared. Ferrozine and ferene S based methods offer higher sensitivity and slightly lower detection limits than method with 1,10-phenantroline, but narrower ranges of linear response. Each system allows detection of iron in micromolar range of concentration with comparable sample throughput (20 injections per hour). The developed flow analysis systems have been successfully applied for determination of iron in diet supplements. The utility of developed analytical systems for iron release studies from drug formulations has also been demonstrated. Copyright © 2017 Elsevier B.V. All rights reserved.

    BACKGROUND: Both iron deficiency (ID) and cardiovascular biomarkers are associated with a poor outcome in heart failure (HF). The relationship between different cardiovascular biomarkers and ID is unknown, and the true prevalence of ID in an outpatient HF clinic is probably overlooked. OBJECTIVES.......043). CONCLUSION: ID is frequent in an outpatient HF clinic. ID is not associated with cardiovascular biomarkers after adjustment for traditional confounders. Inflammation, but not neurohormonal activation is associated with ID in systolic HF. Further studies are needed to understand iron metabolism in elderly HF...

    effect of increased protein intake on mortality (30/181 versus 21/180; RR 1.42, 95% CI 0.85 to 2.37; 4 trials) or number of participants with complications but very low-quality and contradictory evidence of a reduction in unfavourable outcomes (66/113 versus 82/110; RR 0.78, 95% CI 0.65 to 0.95; 2 trials). There was no evidence of an effect on adverse events such as diarrhoea.Trials testing intravenous vitamin B1 and other water soluble vitamins, oral 1-alpha-hydroxycholecalciferol (vitamin D), high dose bolus vitamin D, different oral doses or sources of vitamin D, intravenous or oral iron, ornithine alpha-ketoglutarate versus an isonitrogenous peptide supplement, taurine versus placebo, and a supplement with vitamins, minerals and amino acids, provided low- or very low-quality evidence of no clear effect on mortality or complications, where reported.Based on low-quality evidence, one trial evaluating the use of dietetic assistants to help with feeding indicated that this intervention may reduce mortality (19/145 versus 36/157; RR 0.57, 95% CI 0.34 to 0.95) but not the number of participants with complications (79/130 versus 84/125). There is low-quality evidence that oral multinutrient supplements started before or soon after surgery may prevent complications within the first 12 months after hip fracture, but that they have no clear effect on mortality. There is very low-quality evidence that oral supplements may reduce 'unfavourable outcome' (death or complications) and that they do not result in an increased incidence of vomiting and diarrhoea. Adequately sized randomised trials with robust methodology are required. In particular, the role of dietetic assistants, and peripheral venous feeding or nasogastric feeding in very malnourished people require further evaluation.
