OBJECTIVE: In developing countries, many children are at high risk for both goiter and iron-deficiency anemia. Because iron deficiency may impair thyroid metabolism, the aim of this study was to determine if iron supplementation improves the response to oral iodine in goitrous, iron-deficient anemic children. DESIGN: A trial of oral iodized oil followed by oral iron supplementation in an area of endemic goiter in the western Ivory Coast. METHODS: Goitrous, iodine-deficient children (aged 6-12 years; n=109) were divided into two groups: Group 1 consisted of goitrous children who were not anemic; Group 2 consisted of goitrous children who were iron-deficient anemic. Both groups were given 200mg oral iodine as iodized oil. Thyroid gland volume using ultrasound, urinary iodine concentration (UI), serum thyroxine (T(4)) and whole blood TSH were measured at baseline, and at 1, 5, 10, 15 and 30 weeks post intervention. Beginning at 30 weeks, the anemic group was given 60mg oral iron as ferrous sulfate four times/week for 12 weeks. At 50 and 65 weeks after oral iodine (8 and 23 weeks after completing iron supplementation), UI, TSH, T(4) and thyroid volume were remeasured. RESULTS: The prevalence of goiter at 30 weeks after oral iodine in Groups 1 and 2 was 12% and 64% respectively. Mean percent change in thyroid volume compared with baseline at 30 weeks in Groups 1 and 2 was -45.1% and -21.8% respectively (P<0.001 between groups). After iron supplementation in Group 2, there was a further decrease in mean thyroid volume from baseline in the anemic children (-34.8% and -38.4% at 50 and 65 weeks) and goiter prevalence fell to 31% and 20% at 50 and 65 weeks. CONCLUSION: Iron supplementation may improve the efficacy of oral iodized oil in goitrous children with iron-deficiency 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.

Iron deficiency anemia among pregnant women is a widespread problem in developing countries including Ethiopia, though its influence on neonatal iron status was inconsistently reported in literature. This cross-sectional study was conducted to compare hematologic profiles and iron status of newborns from mothers with different anemia status and determine correlation between maternal and neonatal hematologic profiles and iron status in Ethiopian context. We included 89 mothers and their respective newborns and performed complete blood count and assessed serum ferritin and C-reactive protein levels from blood samples collected from study participants. Maternal median hemoglobin and serum ferritin levels were 12.2 g/dL and 47.0 ng/mL, respectively. The median hemoglobin and serum ferritin levels for the newborns were 16.2 g/dL and 187.6 ng/mL, respectively. The mothers were classified into two groups based on hemoglobin and serum ferritin levels as iron deficient anemic (IDA) and nonanemic (NA) and newborns of IDA mothers had significantly lower levels of serum ferritin (P=0.017) and hemoglobin concentration (P=0.024). Besides, newborns’ ferritin and hemoglobin levels showed significant correlation with maternal hemoglobin (P=0.018;P=0.039) and ferritin (P=0.000;P=0.008) levels. We concluded that maternal IDA may have an effect on the iron stores of newborns.

Iron deficiency anemia is common problem during pregnancy. Red cell size variation (anisocytosis) is the earliest morphologic changes in iron deficiency anemia. Red cell distribution width is a quantitative measure of red cell size variation and it can give the idea of early iron deficiency before other test to become positive.190 pregnant women were included in this study. Red cell distribution width was compared between iron deficient & non-iron deficient pregnant women. Red cell distribution width also compared with Hb level, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration and peripheral blood film in prelatent iron deficiency, latent iron deficiency, mild and moderate iron deficiency anemia. Red cell distribution width had sensitivity 82.3% and specificity 97.4%. Whereas Hb level, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration and peripheral blood film all had 56.6%, 29.2%, 68.1%, 15% and 38.9% sensitivity but specificity was 90.9%, 98.7%, 83.1%, 96.1% and 98.7% in the detection of iron deficiency. Red cell distribution width appears to be a reliable and useful parameter for detection of iron deficiency during pregnancy.

Abstract Context: In patients with coexisting iron-deficiency anemia and subclinical hypothyroidism, anemia does not adequately respond to oral iron therapy. Objective: We studied whether iron-deficiency anemia might indicate treatment of subclinical hypothyroidism. Design: Patients were assigned to a control or experimental group: 240 mg/d oral iron alone (iron group) or 240 mg/d oral iron plus 75 μg/d levothyroxine (iron/levothyroxine group). Levels of hemoglobin, hematocrit, red blood cell count, serum iron levels, ferritin, total iron-binding capacity, TSH, and free T4 were measured before and after treatment. Setting: The study was conducted at a university hospital outpatient clinic. Patients: Fifty-one patients with coexisting iron-deficiency anemia and subclinical hypothyroidism participated in the study. Intervention: Patients were treated as described above in either the iron group or the iron/levothyroxine group. Main Outcome Measure: A clinically satisfactory increase in hemoglobin was regarded as successful. Results: Mean hemoglobin levels increased by 0.4 g/dl in the iron group [95% confidence interval (CI) 0.2–0.7, P = 0.001], whereas it increased by a mean of 1.9 g/dl in the iron/levothyroxine group (95% CI 1.5–2.3, P &lt; 0.0001). The increase in serum iron was greater in the iron/levothyroxine group by a mean of 47.6 μg/dl (95% CI 34.5–60.6, P &lt; 0.0001). Increases in hemoglobin, red blood cells, hematocrit, and serum ferritin levels after treatment were statistically significantly greater in the iron/levothyroxine group (P &lt; 0.0001). Starting hemoglobin and increase in hemoglobin were negatively correlated in the iron/levothyroxine group (r = −0.531, P = 0.006). Conclusions: Subclinical hypothyroidism should be treated in iron-deficiency anemia patients when both conditions coexist. This would provide a desired therapeutic response to oral iron replacement and prevent ineffective iron therapy.

Background: Iron deficiency anemia is the most common form of anemia in India. Hemoglobin A1c (HbA1c) is used in diabetic patients as an index of glycemic control reflecting glucose levels of the previous 3 months. Like blood sugar levels, HbA1c levels are also affected by the presence of variant hemoglobins, hemolytic anemias, nutritional anemias, uremia, pregnancy, and acute blood loss. Previous studies suggest that iron deficiency anemia (IDA) affects the levels of HbA1c. Methods: A prospective observational study on 50 iron deficiency patient cases and 50 healthy control. Exclusion and inclusion criteria were used to recruit cases from the wards and OPDs of the hospital. Appropriate descriptive statistics was used to analyse the data. Results: The HbA1C was significantly higher in the iron deficiency patients as compare to the control (5.88 ± 0.41 vs 5.03 ± 0.17, respectively, P < .05). Conclusion: Our results showed that iron deficiency was associated with higher proportions of HbA1c, which could cause problems in the diagnosis of uncontrolled diabetes mellitus in iron-deficient patients.

Metabolic Remodeling

Iron deficiency is the most prevalent micronutrient disorder globally. When severe, iron deficiency leads to anemia, which can be deleterious to cardiac function. Given the central role of iron and oxygen in cardiac biology, multiple pathways are expected to be altered in iron-deficiency anemia, and identifying these requires an unbiased approach. To investigate these changes, gene expression and metabolism were studied in mice weaned onto an iron-deficient diet for 6 weeks. Whole-exome transcriptomics (RNAseq) identified over 1,500 differentially expressed genes (DEGs), of which 22% were upregulated and 78% were downregulated in the iron-deficient group, relative to control animals on an iron-adjusted diet. The major biological pathways affected were oxidative phosphorylation and pyruvate metabolism, as well as cardiac contraction and responses related to environmental stress. Cardiac metabolism was studied functionally using in vitro and in vivo methodologies. Spectrometric measurement of the activity of the four electron transport chain complexes in total cardiac lysates showed that the activities of Complexes I and IV were reduced in the hearts of iron-deficient animals. Pyruvate metabolism was assessed in vivo using hyperpolarized 13C magnetic resonance spectroscopy (MRS) of hyperpolarized pyruvate. Hearts from iron-deficient and anemic animals showed significantly decreased flux through pyruvate dehydrogenase and increased lactic acid production, consistent with tissue hypoxia and induction of genes coding for glycolytic enzymes and H+-monocarboxylate transport-4. Our results show that iron-deficiency anemia results in a metabolic remodeling toward a glycolytic, lactic acid-producing phenotype, a hallmark of hypoxia.

Abstract Erythrocyte zinc protoporphyrin (ZPP) was measured in 102 women blood donors to evaluate its usefulness in screening for evolving iron deficiency anemia, a reason for the deferral of donors. The results were compared with serum ferritin determinations. Five women were deferred before their first donation and eight women were deferred after one or two donations. Women with increased ZPP values all had low serum ferritin concentrations, indicating iron-deficient erythropoiesis that was caused by iron depletion. The positive predictive value of an increased ZPP in predicting deferral of the donor after one or two donations was 75%, whereas a serum ferritin concentration ≤12 μg/L predicted deferral in 26% of the donors. The results indicate that the ZPP test can be recommended as a feasible and inexpensive predonation test to determine a subset of donors with iron-deficient erythropoiesis at risk of developing iron deficiency anemia.

Abstract 32P in membrane phosphatidylethanolamine (PE) and red cell 14C, reflecting cytoplasmic hemoglobin, were measured sequentially in rats given transfusions of doubly-labeled reticulocytes. With reticulocytes from normal rats there was a small decline in the levels of both the membrane and the cytoplasmic labels; the changes were almost parellel, although loss of membrane PE-32P exceeded that of 14C to a small extent. By contrast, with "stress reticulocytes" from bled donors, there was a markedly disproportionate loss of the membrane label; this asymmetrical loss of membrane material was diminished when recipients had been splenectomized. With transfusions of doubly-labeled reticulocytes from rats with severe iron deficiency anemia, there was a marked loss of both membrane PE-32P and red cell 14C which was only moderately asymmetrical. The asymmetrical loss of the membrane label found with stress reticulocytes supports the conclusion that these cells undergo a process of surface remodeling during their maturation in the peripheral blood. The spleen is partly responsible for this process. Normal reticulocytes also appear to undergo a minor degree of remodeling. On the other hand, the almost symmetrical loss of membrane and cytoplasmic label observed with reticulocytes from iron deficient rats indicates that many of the cells in this model of ineffective erythropoiesis are hemolyzed in their entirety. These experiments demonstrate that stress reticulocytes differ under different conditions and may lose cellular material by two, possibly interrelated, mechanisms: surface remodeling or whole-cell hemolysis.

According to the World Health Organization, iron deficiency anemia affects more than 30% of the world's population. In the Russian Federation, anemia is diagnosed in 35,6% of pregnant women, and the prevalence rate among children in the first year of life is about 83,8 ‰. In the Stavropol Territory, more than 10 thousand cases of anemia are registered annually, of which half are the first. More than 20% of these cases are diagnosed in children and adolescents. In this regard, there is a steady dynamics in the consumption of a specific nomenclature of antianemic drugs at various levels of the drug supply system: federal, regional and municipal. The purpose of the work was to analyze the availability of antianemic drugs used in the treatment of patients living in the city of Pyatigorsk, Stavropol Territory. In the course of work, we used methods of content analysis, analytical, direct observation, grouping and comparison. The studies were carried out from november 2019 to february 2020 on the basis of 11 pharmacy of various legal forms included in the pharmacy chains «Vita +», «Gorzdrav», and the «Pharmacy Warehouse» located in Pyatigorsk. When studying the pharmaceutical range of antianemic drugs, it was found that at the municipal level it includes 12 trade names of drugs based on Fe2+ and Fe3+ ions. Analysis of the liquidity of the prices of antianemic drugs in the pharmacies of Pyatigorsk and the solvency of the population showed the economic affordability of most of the studied range of drugs for patients. An analysis of the width and depth of the range of antianemic drugs for the treatment of iron deficiency anemia revealed the presence of reserves for increasing the range of products for patients. It is concluded that it is necessary to consolidate the efforts of medical and pharmaceutical workers to expand the range of antianemic drugs used by patients, which will increase the quality of medical care.
