Filter by:The objective of this study is to compare HIV infected children to uninfected children regarding 1) quantifying iron absorption from iron fortified maize porridge, lipid-based food supplements and oral iron supplements, and 2) quantifying the daily iron requirement.
Iron deficiency anaemia is a common condition among colorectal surgical patient. Untreated anaemia would lead to increase in blood transfusion, surgical complications and mortality. Treatment with oral iron sulphate is poorly tolerated due to side effects. Intravenous iron supplement provides an alternative way to rapidly replace iron deficit during the preoperative period among surgical patients. Evidence is growing for its effect in rising hemoglobin level and reducing blood transfusion, at the same time supporting its safety profile. The investigators plan for a single-centered, randomized controlled trial to examine the effect of intravenous iron compared to standard care in terms of hemoglobin level/serum ferritin increment, need for blood transfusion, duration of hospital stay, quality of recovery and surgical complication rate, as well as safety profile among colorectal cancer surgical patients in Hong Kong. The investigator propose the following pilot RCT for exploring the effect size and study process in conducting the above-mentioned large-scale RCT.
Iron deficiency is thought to be the most common nutrient deficiency among pregnant women and the most common cause of anemia in pregnancy. The consequences of iron deficiency anemia are serious and can include diminished intellectual and productive capacity and possibly increased susceptibility to infection in mothers and infants, low birthweight, and premature births, hence the importance of appropriate treatment during pregnancy. Most guidelines recommend an increase in iron consumption by about 15-30 mg/day, an amount readily met by most prenatal vitamin formulations. This is adequate supplementation for non-anemic and non-iron-deficient women. However, women with iron deficiency anemia should receive an additional 30-20 mg/day until the anemia is corrected. It is not clear whether intermittent administration of oral iron is equivalent to once daily to rise the hemoglobin levels in pregnant women with iron deficiency anemia. Alternate day treatment with supplemental iron has been suggested as a way to improve its absorption because daily doses may suppress the mucosal uptake of iron even in the presence of iron deficiency until the intestinal mucosa completes its turnover. Another possible factor associated with the frequency of iron dosing is related to hepcidin, the central regulatory molecule in the metabolism of iron in mammals. The synthesis of hepcidin is controlled by 3 kinds of signals: inflammation; the need for increased erythropoiesis, and an iron status signal based on plasma iron levels and iron stores. If plasma iron levels or iron stores are increased, the resulting signal increases hepcidin levels, thereby blocking iron absorption and its release from stores (liver, macrophages) and preventing iron overload.This hepcidin effect, suppressing iron absorption, could last as long as 48h. In this study, the researchers aim to determine if alternate day dosing of iron in pregnant women with iron deficiency anemia results in improved levels of hemoglobin or hematocrit and ferritin. Hepcidin levels will be compared between patients on daily iron supplementation versus alternate day supplementation. The researchers will also evaluate if alternate day dosing of iron supplementation results in a better side effect profile, and with better patient compliance.
Iron deficiency anemia (IDA) is the condition in which there is anemia due to a lack of iron. The oral route is preferred to the parenteral route to replace iron stores [Sharma JB; et al., 2004]. Inorganic iron has poor bio-availability in addition to many side effects, including gastrointestinal discomfort, nausea, vomiting, diarrhea and constipation and it may sometimes increase susceptibility to infection [ So¨lvell L; et al., 1970].
Iron is involved in essential functions of the body. It allows the transport of oxygen in the blood, via hemoglobin, at the muscular level, via myoglobin, and it is also involved in cellular metabolism in general, in particular for the production of ATP at the mitochondrial level, within the cytochromes and iron-sulfur proteins of the respiratory chain. Recently, iron deficiency has been identified as an important prognostic factor in heart failure patients. Iron therapy improves symptoms and physical performances of heart failure patients, even in the absence of anemia. As a result, the correction of iron deficiency is now proposed as one of the therapies for heart failure. However, the pathophysiology of the association between cardiac dysfunction and iron deficiency is still poorly understood. The investigators previously developed a mouse model of iron deficiency without anemia, in which the investigators observed impaired physical performances, a decrease of left ventricular ejection fraction, and a decrease in mitochondrial complex I activity. These abnormalities were normalized after iron injection. These animal data suggest that iron deficiency is responsible for left ventricular dysfunction secondary to mitochondrial I complex abnormalities, and that iron therapy corrects them. Iron deficiency is very common in the preoperative period of cardiac surgery, affecting 40 to 50% of patients. During this surgery, it is possible to perform a myocardial biopsy without risk to the patient. The purpose of this study is to verify in patients requiring valvular heart surgery, if iron deficiency is responsible for a decrease in mitochondrial complex I activity and a decrease in cardiac function during the perioperative period, and to verify whether iron treatment improves these abnormalities.
A multi-center,randomized,double-blind,controlled clinical trial was used to investigate the effectiveness of the treatment of infant iron deficiency anemia by taking ferralia and different contents lactoferrin.
The scope of this study is to compare the efficacy of the new oral formulation of Fe-ASP to oral ferrous sulfate in patients with iron deficiency anemia (IDA) for the restoration of decreased circulating Hb. The improvement of symptoms of anemia, the restoration of biomarkers of iron deficiency into the normal range and the incidence of GI tract side effects are the study secondary endpoints.
The primary objective of this study is to demonstrate the efficacy and safety of intravenous ferric carboxymaltose (FCM), compared to oral iron, in pediatric participants who have iron deficiency anemia.
This research project is aimed at combating the nutritional deficiencies (Iron deficiency anemia) of reproductive aged females belonging to the underprivileged group of the society. Since anemia is one of the causes of still child-birth, preterm and low birth weight babies causing cognitive disabilities during the later years of life, So, it needs to be treated on priority bases.
This study evaluates the safety, tolerability, and activity of BioFe in the dietary management of iron deficiency in adults.
