The Optimization of Bioavailability From Iron Supplements: Study 1
Iron DeficiencyAnemia1 moreIron deficiency (ID) with or without anaemia (IDA) is a major public health problem worldwide, especially in women of reproductive age and young children. Iron supplementation is an effective strategy to prevent and treat ID and IDA. There is a lack of data on iron bioavailability from different supplementation regimens and how to optimize bioavailability in a cost-effective and patient-friendly way. The present study will test whether the fractional and total iron absorption from iron supplements (60 mg) administered daily for 14 days differs from that of iron supplements (60 mg) administered every second day for 28 days. The prevailing serum hepcidin concentration (SHep) is the major determinant of iron absorption and erythrocyte iron utilization. Therefore we will monitor SHep during the whole supplementation period. We hypothesize that the fractional and total iron absorption from the daily administration of 60 mg is lower than that from the administration on every second day due to increased SHep levels when supplements are administered daily. The study will provide important insights about the optimization of iron bioavailability from different supplementation regimens including the performance of SHep, a key regulator of human iron metabolism.
Safe and Efficacious Iron for Children in Kenya
AnaemiaThis study will determine whether the haemoglobin response to daily home fortification for 30 days with 3mg iron as NaFeEDTA is non-inferior to 12.5 mg iron as encapsulated ferrous fumarate.
Unrelated HSCT in Patients With Fanconi Anemia
Fanconi AnemiaThe protocol is designed for the compassionate treatment of patients with Fanconi Anemia who do not have an HLA-matched sibling donor. The purpose of this study is to determine the likelihood of engraftment in Fanconi Anemia patients using total body irradiation (TBI), cyclophosphamide (CY), fludarabine (FLU) and antithymocyte globulin (ATG) followed by an unrelated donor hematopoietic cell transplant with T-cell depletion using the CliniMACS device.
Prevention of Severe Anaemia in Gambian Children
AnemiaSevere anaemia is a frequent cause of admission to hospitals in tropical Africa and about 10% of such children die. In endemic countries, anaemia has multiple causes such as nutritional deficiencies, infections and haemoglobinopathies. However, Plasmodium falciparum infection is believed to be the major contributory factor to the aetiology of severe anaemia. Severe anaemia is usually treated by blood transfusion although transfusion carries the attendant risk of transmission of HIV and other blood-borne infections. Thus, there is a need to explore novel strategies to reduce the incidence of severe anaemia in high-risk groups such as children with suboptimal haemoglobin levels because these children are at increased risk of developing severe anaemia if they develop a malaria infection before their haemoglobin level has normalized. Therefore, it is proposed to study whether monthly chemoprophylaxis with sulphadoxine/pyrimethamine (S/P) given during malaria transmission season can protect Gambian children from developing severe anaemia. After receiving treatment from the hospital, 1200 children admitted to the hospital with a haematocrit of less than 21% were randomised to receive either monthly S/P or placebo during the rest of the malaria transmission season. Morbidity was monitored throughout the rainy season. Study subjects were seen at the end of the dry season to document morbidity and mortality.
Hydroxyurea to Prevent Organ Damage in Children With Sickle Cell Anemia
Hematologic DiseasesAnemia1 moreThe purpose of this study is to determine if hydroxyurea therapy is effective in the prevention of chronic end organ damage in pediatric patients with sickle cell anemia.
Phase I/II Pilot Study of Mixed Chimerism to Treat Hemoglobinopathies
AnemiaSickle Cell6 moreThe goal of this research study is to establish chimerism and avoid graft-versus-host disease in patients with hemoglobinopathies.
Evaluation of Iron Supplementation During Darbepoetin Alfa Treatment in Prophylaxis of Severe Anaemia...
NeoplasmsAnemiaThe purpose of this study is to evaluate the response rate obtained in an heterogeneous oncologic population treated by chemotherapy, and either by Darbepoetin alfa classic treatment or by association of Darbepoetin alfa -ferric saccharose systematic supplementation, administered concomitantly with chemotherapy.
Sparing Conversion to Abnormal TCD (Transcranial Doppler) Elevation (SCATE)
Sickle Cell AnemiaThe primary goal of the Phase III SCATE trial is to compare 30 months of alternative therapy (hydroxyurea) to standard care (observation) in children with sickle cell anemia and conditional (170 - 199cm/sec) Transcranial Doppler (TCD) velocities. For the alternative regimen (hydroxyurea) to be declared superior to the standard treatment regimen (observation), the hydroxyurea-treated group must have a three-fold reduction in the incidence of conversion to abnormal TCD velocities (≥ 200 cm/sec), compared to the standard treatment arm.

Delayed Cord Clamping in Premature Infants
HypothermiaAnemiaDelayed cord clamping has been shown to decrease the risk of bleeding in the brain of premature infants. However this procedure is not standard due to concerns that the premature infant will get too cold. In this study the investigators look at using a plastic covering and a chemical warmer to keep the small premature baby warm while waiting 30-60 seconds to clamp the umbilical cord.
