Background: Hepcidin-25 is a 25 amino acid hepatokine and a key regulator of iron metabolism related to iron deficiency anemia. Recent studies have suggested that an elevated hepcidin level is correlated with low energy availability. Leptin is an appetite-suppressing adipokine and has been reported to stimulate hepcidin production in animals and cultured cells. While leptin is modulated by exercise, it is known that endurance runners and sprinters practice different types of exercise. This study investigated and compared the relationships between hepcidin and leptin levels, iron status, and body fat to understand better the risk of iron deficiency anemia in endurance runners and sprinters.Methods: Thirty-six male college track and field athletes (15 endurance runners and 21 sprinters) were recruited for this study. Dietary intake, body composition, and blood levels of ferritin, hepcidin-25, leptin, and adiponectin were measured. Correlations between hepcidin levels and ferritin, body fat, leptin, and adiponectin were evaluated using Pearson's correlation coefficient for each group.Results: The endurance runners had lower hepcidin levels and higher leptin and adiponectin levels compared with sprinters. Ferritin was positively correlated with hepcidin-25 levels in both the endurance and sprinter groups. A positive correlation was observed between hepcidin-25 and body fat or leptin levels only in sprinters.Conclusion: This is the first study investigating the relationship between blood levels of hepcidin and leptin in athletes. The positive correlation between hepcidin-25 and leptin was observed in sprinters but not endurance runners.

Purpose Iron deficiency anemia (IDA) is one of the most major micronutrient deficiencies worldwide. Food fortification is one strategy for reducing IDA in the population despite concern regarding the gut pathogenic bacteria overgrowth. The purpose of this study was to evaluate the effect of iron encapsulation in banana peel matrix on iron status and gut microbiota composition in iron deficiency anemia. Design/methodology/approach Anemia was induced in 35 male Sprague Dawley rats of age two weeks by the administration of iron-free diet for two weeks. Rats then randomly divided into control, iron-fortified tempeh (temFe) dose 10 and 20 ppm, iron matrix-fortified tempeh dose 10 and 20 ppm and iron matrix fortified tempeh dose 10 and 20 ppm with probiotic mixture. Blood was drawn at Weeks 2 and 6 for hemoglobin and serum iron analysis. Rats were sacrificed at the end of Week 6, and cecal contents were collected for Lactobacillus, Bifidobacteria and Enterobactericeae analysis. Findings Hemoglobin and serum iron were significantly increased (p < 0.05) in all iron-fortified group with the highest value found in iron matrix dose 20 ppm (10.71 ± 0.15 g/dl and 335.83 ± 2.17 µg/dl, respectively). The cecal Lactobacillus and Bifidobacteria did not differ significantly between groups. Cecal Enterobactericeae was significantly different (p < 0.05) among groups with the lowest level in the temFe-20 (2.65 ± 0.78 log CFU) group. Research limitations/implications The use of commercial inoculum instead of pure Rhizopus oligosporus mold for developing the fortified tempeh may impact the effect of product on cecal gut microbiota composition, as different molds and lactic acid bacteria can grow in tempeh when using commercial inoculum. Social implications In Indonesia, iron fortification is conducted primarily in noodles and flour that limits the impact of iron fortification for reducing IDA in population. Iron fortification in food that was daily consumed by people, that is, tempeh, is potential strategy in reducing IDA in population. Originality/value Tempeh fortification using encapsulated iron improved iron status and gut microbiota composition in iron deficiency anemia.

Introduction. Neonatal calves are often deficient in iron. Accumulating evidence indicates that iron status is associated with disease pathologies including diarrhea. Our objective was to examine the association between iron status and gut function in neonatal calves with and without a history of calf diarrhea. Materials and Methods. Calves were divided into two groups based on their history of diarrhea; the first group were diarrheic calves (n=6) and the second group were non-diarrheic healthy calves (n=6). Blood samples (n=12) were collected at day 12 of age and erythrogram determination and measurements of serum iron and total iron binding capacity were performed. Hematological values were measured using an automatic analyzer, and biochemical properties were determined spectrophotometrically. Fecal samples were obtained from all calves and pH measured using semi quantitative test strips as well as being examined by bacterial cultivation for enterotoxigenic Escherichia coli, Salmonella spp. and Clostridium perfringens, by RT-PCR for the presence of bovine rotavirus, bovine coronavirus and bovine viral diarrhea virus, and by microscopy for the presence of Cryptosporidium parvum. Results and Conclusions. There were significant iron-related changes for most hematological indices in diarrheic calves; and iron (Fe) deficiency and microcytic, hypochromic anemia were diagnosed. The pH of the feces was significantly higher in diarrheic calves than in the non-diarrheic healthy group (P<0.01). All fecal samples were negative for the analyzed enteric pathogens. According to the results obtained, calves experiencing iron deficiency anemia exhibit changes in gut function leading to diarrhea as compared with a matched group of healthy calves.

Iron amino acid chelates, such as iron glycinate chelates, have been developed to be used as food fortificants and therapeutic agents in the prevention and treatment of iron deficiency anemia. Ferrous bis-glycine chelate (FeBC), ferric tris-glycine chelate, ferric glycinate, and ferrous bis-glycinate hydrochloride are available commercially. FeBC is the most studied and used form. Iron absorption from FeBC is affected by enhancers and inhibitors of iron absorption, but to a lesser extent than ferrous sulfate. Its absorption is regulated by iron stores. FeBC is better absorbed from milk, wheat, whole maize flour, and precooked corn flour than is ferrous sulfate. Supplementation trials have demonstrated that FeBC is efficacious in treating iron deficiency anemia. Consumption of FeBC-fortified liquid milk, dairy products, wheat rolls, and multi-nutrient beverages is associated with an improvement of iron status. The main limitations to the widespread use of FeBC in national fortification programs are the cost and the potential for promoting organoleptic changes in some food matrices. Additional research is required to establish the bioavailability of FeBC in different food matrices. Other amino acid chelates should also be evaluated. Finally there is an urgent need for more rigorous efficacy trials designed to define the relative merits of amino acid chelates when compared with bioavailable iron salts such as ferrous sulfate and ferrous fumarate and to determine appropriate fortification levels

Detailed Medical History

Introduction: In developing countries like Nepal, iron deficiency anemia (IDA) is one of the major concern. The high rate incidence has been related to insufficient  iron  intake, accompanied  by chronic  intestinal  blood  loss  due  to parasitic  and  malarial infections. Therefore, a study was conducted to evaluate the prevalence of IDA in anemic patients of Universal College of Medical Sciences-Teaching Hospital (UCMS-TH), South Western region, Nepal. Material and Method It was a hospital based cross sectional study comprised of 100 anemic patients. Their detailed medical history and lab investigations, focusing on hematological parameters were documented. Peripheral smear examination and serum ferritin estimation were done to observe red cell morphology and iron status respectively.  Results: This study revealed that out of 100 anemic patients, 35% were that of IDA. The most affected age group was 21-40 years with frequency 42.55%. IDA was more common in females (42.85%) than in male (21.62%). Out of 100 anemic patients, microcytic hypochromic anemia was predominant in 47% followed by macrocytic anemia (31%) and then normocytic normochromic anemia (22%). Out of 47 microcytic hypochromic anemic patients, 12 had normal serum ferritin. There was a statistical significant difference in Hb (p=0.011), MCV (p=0.0001), MCH (p=0.0001), MCHC (p=0.0001) and serum ferritin (p=0.0001) among all types of anemia. There was a statistical significant positive correlation of ferritin with Hemoglobin (0.257, p= 0.01), MCV (0.772, p= 0.0001), MCH (0.741, p=0.0001) and MCHC (0.494, p=0.0001).  Conclusion: The peripheral smear in conjunction with serum ferritin estimation needs to be included for susceptible individuals to screen the IDA and other types of anemia.

Abstract Objectives To determine whether rapid correction of iron deficiency using intramuscular iron dextran normalizes serum metabolomic changes in a nonhuman primate model of iron deficiency anemia (IDA). Methods Blood was collected from naturally iron-sufficient (IS; n = 10) and IDA (n = 12) male and female infant rhesus monkeys (Macaca mulatta) at 6 months of age. IDA infants were treated with intramuscular injections of iron dextran, 10 mg/weekly for 4–8 weeks. Iron status was reevaluated following treatment using hematological measurements and sera were metabolically profiled using HPLC/MS with isobaric standards for identification and quantification. Results Early-life iron deficiency anemia negatively affects many cellular metabolic processes, including energy production, electron transport, and oxidative degradation of toxins. Slow iron repletion with dietary supplementation restores iron deficient monkeys from a hematological perspective, but the serum metabolomic profile remains differed from monkeys that had been iron sufficient their entire life. Whether rapid iron restoration through intramuscular injections of iron dextran normalizes serum metabolomic profile is not known. A total of 654 metabolites were measured with differences in 53 metabolites identified between IS and IDA monkeys at 6 months (P 0.05). Pathway analyses provided evidence of altered liver function, hypometabolic state, differential essential fatty acid production, irregular inosine and guanosine metabolism, and atypical bile acid production in IDA infants. After treatment, iron-related hematological parameters had recovered, but the formerly IDA infants remained metabolically distinct from the IS infants, with 225 metabolites differentially expressed between the groups. Conclusions As with slow iron repletion, rapid iron repletion does not normalize the altered serum metabolomic profile in rhesus infants with IDA, suggesting the need for iron supplementation in the pre-anemic stage.
