Intravenous Versus Oral Iron for Treating Iron-Deficiency Anemia in Pregnancy

Iron Deficiency AnemiaPregnancy

Double blind, placebo controlled, multicenter randomized trial in pregnant women in the U.S. (N=746) to test the central hypothesis that IV iron in pregnant women with moderate-to-severe IDA (Hb<10 g/dL and ferritin<30 ng/mL) at 24 - 28 weeks will be effective, safe and cost-effective in reducing severe maternal morbidity-as measured by peripartum blood transfusion-and will also improve offspring neurodevelopment.

Trial of IV vs Oral Iron Treatment of Iron Deficiency Anemia in the Post-Operative Bariatric Surgical...

Iron Deficiency Anemia

Given the limited long-term effectiveness of traditional weight loss methods, bariatric surgery is increasingly becoming the preferred option for sustained weight loss. With the ascendancy of the laparoscopic approach, the two most common procedures are the Roux-en-Y gastric bypass (RYGB) and the vertical sleeve gastrectomy (VSG). Because bariatric surgery decreases nutrient intake through restriction, malabsorption, or both, and given that obese patients are often malnourished even before surgery, postoperative micronutrient deficiency, particularly of iron, can be a serious complication and difficult to treat. Iron deficiency anemia has been reported to be as high as 49% in the post-bariatric surgical patient. The current standard for correcting iron deficiency anemia in the post-operative bariatric surgical patient is oral iron supplements. However, oral iron therapy is known for its caustic effects on the gastric mucosa causing gastric irritation, nausea, epigastric discomfort and constipation. These debilitating symptoms lead to poor adherence and lower long and short-term efficacy. Furthermore, iron absorption from oral iron supplements when taken with food in patients with low iron stores ranges from 2 to 13% and without food 5 to 28%. An alternative and more effective method of iron replenishment is the use of intravenous iron. A litany of published trials, without contradiction, show marked superiority of intravenous iron in improving hemoglobin concentrations and iron parameters when compared to historical controls. Nonetheless, the current recommendations of the American Society of Metabolic and Bariatric Surgery nutritional guidelines, state that oral iron supplementation for IDA is the recommended first line of treatment. Studies are lacking that compare the efficacy of oral versus intravenous (IV) iron therapy for the treatment of IDA in the post-bariatric surgical patient. The aim of our study is to compare two accepted treatments for iron deficiency anemia (oral ferrous sulfate and intravenous ferumoxytol) for efficacy and speed of response in the treatment of IDA in the post-operative bariatric surgical patient. In this study, 104 bariatric surgical post-operative patients will be randomly assigned 52 each to oral or 52 to a single dose IV iron treatment using double-blind procedures. The primary outcome will be determined at 6 weeks of treatment with a follow-up at 12 months after treatment. Non-responders at 6 weeks after treatment may, if they qualify (based on inclusion/exclusion criteria), have an open-label IV iron treatment and will be followed with the same evaluations used after the first IV iron treatments.

Meals to Improve Absorption of Iron Supplements

Iron-deficiencyIron Deficiency Anemia1 more

One of the targeted objectives of Healthy People 2020 is to reduce iron deficiency among women of reproductive age (WRA). Consuming foods rich in iron and/or oral iron supplementation is typically recommended to improve iron status; however, global rates of iron deficiency remain high. Thus, nutritional strategies to improve/maintain iron status are warranted. Dietary iron is found in two different forms: heme and non-heme iron. Non-heme iron is found in plant-based sources and is commonly used as a supplement and food fortificant. Absorption of non-heme iron is low compared to heme iron, which is found in animal sources, such as beef. Studies have also demonstrated that beef contains an unidentified factor that stimulates the absorption of non-heme iron. The primary objective of the proposed study is to determine the effects of incorporating daily meals containing beef or plant-based alternative with or without an iron supplement on indicators of iron status in iron-deficient WRA.

Chocolate and Physical Exercise to Reduce Malnutrition in Pre-dementia Aged People

DementiaDementia6 more

We hypothesize that the antioxidant and cytoprotective functions of vitamin E combined with the cortisol-lowering effect of chocolate polyphenols and physical activity may help prevent the age-dependent decline of mitochondrial function and nutrient metabolism in skeletal muscle, key underpinning events in protein-energy malnutrition (PEM) and muscle wasting in the elderly. To test this hypothesis, a vitamin E functionalized dark chocolate rich in polyphenols will be developed with the collaboration of Nestlè Company, and its effects will be investigated combined with physical activity in a 6-month randomized case-control trial on pre-dementia elderly patients, a well-defined population of subjects at risk of undernutrition and frailty. Subjects stabilized on a protein-rich diet (0.9-1.0 g protein/Kg ideal body weight/day) and physical exercise program (High Intensity Interval Training specifically developed for these subjects), will be randomized in 3 groups (n = 34 each): controls (Group A) will maintain the baseline diet and cases will receive either 30 g/day of dark chocolate containing 500 mg total polyphenols (corresponding to 60 mg epicatechin) and 100 mg vitamin E (as RRR-alpha-tocopherol) (Group B) or the high polyphenol chocolate without additional vitamin E (Group C). Diet will be isocaloric and with the same intake of polyphenols and vitamin E in the 3 groups. Muscle mass will be the primary endpoint and other clinical endpoints will include neurocognitive status and previously identified biomolecular indices of frailty in pre-dementia patients. Muscle biopsies will be collected to assess myocyte contraction and mitochondrial metabolism. Laboratory endpoints will include the nutritional compliance to the proposed intervention (blood polyphenols and vitamin E status and metabolism), 24-h salivary cortisol, steroid hormones and IGF-1, and molecular indices of inflammation, oxidant stress, cell death and autophagy. These parameters will be investigated in muscle and blood cells by state-of-the-art omics techniques. Molecular and nutritional findings will also be confirmed in vitro using skeletal myotubes, blood leukocytes and neural cell lines. Clinical and laboratory results will be processed by a dedicated bioinformatics platform (developed with the external collaboration of the omics company Molecular Horizon Srl) to interpret the molecular response to the nutritional intervention and to personalize its application.

Analysis of the Effect of Iron Supplements on Iron Deficiency Anemia in Pregnancy

Iron Deficiency Anemia of PregnancyIron Storage Disease

Subjects were tested for hemoglobin, ferritin, serum iron, transferrin saturation and reticulocyte count during routine prenatal examination at 24-26 weeks of gestation, and blood samples were taken for serum hepcidin detection in the laboratory and the values were recorded. Those who met the criteria were included in the study group, signed the informed consent form and randomized into groups, and were given different drug administration schemes (150mg orally every day, 300mg orally every day, 150mg orally every other day, 300mg orally every other day, intravenous). At the same time, each subject was given anemia diet education, and all subjects were given folic acid 400ug/d and vitamin C 0.5g/d orally during the treatment period. If the subjects were in the oral iron group, the same time of oral iron was determined as 20 o'clock ± 1 hour in the evening, and the oral iron was not taken with other drugs; If the subject is in the intravenous medication group, the medication is scheduled to be administered at a uniform time of 8 o'clock ± 1 hour in the morning. The above subjects were followed up. Hemoglobin, ferritin, serum iron, transferrin saturation and reticulocyte count were performed at 30-32 and 37 weeks of pregnancy and delivery, and blood samples were taken for serum hepcidin detection in the laboratory and the values were recorded. The adverse reactions were investigated with a questionnaire at the last prenatal examination before delivery. After full term delivery, the patient fills in the delivery information and enters it into the database. Finally, the data statistician and the above personnel used the blind method for statistical analysis and reached a conclusion.
