Filter by:A monocentric prospective study was conducted to find the relevance between the level of fetal hemoglobin and short-term complications in extremely preterm infants
This is a phase II, open-label, prospective study of T cell receptor alpha/beta depletion (α/β TCD) peripheral blood stem cell (PBSC) transplantation for children and adults with hematological malignancies
The aim of this study is to investigate the relationship between cerebral and peripheral oxygenation and oxygen extraction, as measured by NIRS (near-infrared spectroscopy ), and the FHbF (fraction of fetal hemoglobin) and absolute HbF (fetal hemoglobin) concentration in postnatal conditions in term and preterm neonates.
Repeated transfusions have been associated with very poor outcome of preterm infants. Fetal hemoglobin (HbF) and adult Hb (HbA) have different affinity for oxygen. The high level of adult Hb may contribute to exacerbating the oxidative damage responsible for prematurity diseases. The investigators hypothesized that transfusing red blood cells (RBC) obtained from allogeneic cord blood (CB) of healthy full-term babies (which contains almost exclusively HbF) may prevent the non-physiological decrease of HbF in premature neonates, likewise protecting them from oxygen radical diseases. Cord blood transfusion in preterms - CB TRIP - is a monocentric prospective nonrandomized study aimed to monitor HbF levels in preterm neonates receiving RBC transfusions from either umbilical blood of full-term healthy babies (CB-RBC) and/or from adult donors (A-RBC).
The overall purpose of this study is to obtain a better understanding of the biological response of red blood cells to sulforaphane contained in fresh broccoli sprouts that have been put through a blending process. This study will use commercially available fresh broccoli sprouts certified by Brassica Protection Products LLC (BroccoSprouts®). This product can also be purchased at some local grocery stores in the produce section. It is believed that NRF2, a transcription factor encoded by the NFE2L2 gene, plays a role in the regulation of defense against oxidative stress. The detrimental accelerated breakdown of sickle cell disease (SCD) red blood cells (SS RBC) is partially due to reduced anti-oxidative capacity. Previous analysis of SS RBC microRNAs revealed that a reduced level of NRF2, the master regulator of anti-oxidative stress capacity, contributes to reduced resistance to oxidative stress and increased hemolysis; NRF2 also induces fetal hemoglobin (HbF), which is known to prevent SS RBC sickling. First, erythroid progenitors from normal and SCD subjects will be tested ex-vivo to find out how sulforaphane, a natural NRF2 activator, affects the oxidative stress capacity, HbF expression, and microRNA expression of red cells. Second, a pilot clinical trial will be conducted to determine the safety and physiological effects of 3 weeks of daily consumption of broccoli sprout homogenate in a cohort of Hb SS/SB0 thalassemia adult SCD patients. During this study, subjects RBCs will be assayed for changes in anti-oxidative stress capacity and microRNA composition in mature SCD red blood cells.
