5 Clinical Trials for Various Conditions
This study compares the iron levels in very preterm infants receiving donor breast (DBM) milk to very preterm infants receiving maternal breast milk (MBM).
A serum ferritin level can reflect the total body iron content, thus a very low serum ferritin is commonly used as an indicator of iron deficiency and a very high serum ferritin is commonly used as a marker of iron overload. Ferritin is a shell of protein in which iron is stored. Ferritin is an acute phase reactant, and serum ferritin levels can increase during inflammatory conditions. Consequently, an elevated ferritin level might mean there is an excess of storage iron, or might simply mean that inflammation has resulted in high levels of the ferritin shell, containing little iron. The research team is able to quantify the amount of iron in ferritin using inductively conducted plasma mass spectrometry, in the Heme and Iron Core Laboratory at the University of Utah. Thus, it can be determined whether in a child with a very high serum ferritin level, that ferritin is loaded with iron or is actually very low in iron. Neonates and young children with certain liver disorders characteristically have a very high serum ferritin level. These conditions are gestational alloimmune liver disease (GALD) and hemophagocytic lymphohistiocytosis (HLH). It is not clear what the iron content of the ferritin is in these neonates. Knowing this will be a step toward understanding whether the pathogenesis of these conditions involves iron overload. Additionally, if urine ferritin and iron levels correlate with serum ferritin and iron levels, urine may be used as a non-invasive way to monitor iron status. In this study, serum and urine samples will be collected from children with high serum ferritin levels and confirmed iron toxicity. Both ferritin and iron content within ferritin will be measured in the serum and urine samples and compared for correlation.
The goal of this work is to study the effects of twice daily ingestion of a whey protein, rice protein, or maltodextrin drink enriched with lactoferrin- (200 mg), iron (6 mg) and vitamin B12 (5.2 µg) for 16-weeks on iron metabolism and inflammatory markers in active young females. It is expected that the females consuming containing lactoferrin-, iron, and vitamin B12-enriched whey will 1) improve serum ferritin status; 2) reduce inflammation; 3) improve markers of iron metabolism, such as Hemoglobin (Hb), red blood cell count (RBC) and hematocrit (Hc) compared to women who consume the rice protein or maltodextrin control drink. Blood will be drawn before the beginning of the supplemental period (week 0) and end the end of the intervention phase (week 16).
The specific aims of the current study were: 1) To determine the prevalence of IDNA in a sample of Mexican women of reproductive age and 2) To determine how iron supplementation in IDNA women influences physical work capacity during submaximal exercise . The researchers hypothesized that marginally iron depleted women will have improved physical work capacity during submaximal intermittent exercise tests after dietary iron supplementation. However, no improvement in peak maximal oxygen consumption after dietary iron supplementation because they will remain non-anemic.
Iron deficiency (ID) affects \~30% of female athletes, and its consequences are highly relevant to athletic performance. Poor iron (Fe) uptake remains a major factor in the development of ID. While animal studies suggest that prebiotics may improve Fe uptake, this has not been well-studied in humans. The main objective of the proposed study is to determine the effects of synbiotic supplementation on the Fe status of ID female athletes during Fe repletion.
