|Official Title ICMJE||Collection and Storage of Umbilical Cord Hematopoietic Stem Cells for Sickle Cell Disease Therapy|
This study will determine the best ways to collect, process and store umbilical cord blood from babies with sickle cell disease, sickle cell trait and unaffected babies. Sickle cell disease is an abnormality of the hemoglobin in red blood cells that causes the cells to change shape and clump together, preventing their normal flow in the bloodstream. This impairs blood flow to various organs, and the resulting oxygen deprivation causes organ damage.
Cord blood is rich in stem cells (cells produced in the bone marrow that mature to different types of blood cells), which may prove useful in new sickle cell therapies. However, cord blood from babies with sickle cell trait, sickle cell disease and normal babies may act differently under laboratory conditions, so it is important to learn how best to work with blood from all three groups of babies for future use in possible treatments.
Pregnant women between 18 and 45 years of age who are at risk of having an infant with sickle cell disease and normal volunteers who are pregnant and not at risk for this disease may be eligible for this study. Potential participants will be counseled about donating her infant s blood in order to make an informed choice.
All women who participate in the study will provide a medical history and have blood collected from the umbilical cord and placenta (afterbirth) after the baby s delivery. The blood will be tested for various infectious diseases, processed, frozen and stored for research purposes. In addition, blood from women with babies at risk for sickle cell disease will be tested for the presence of the sickle cell gene, tissue typed, and used for research as follows:
Participants and their family doctor or the baby s pediatrician will be contacted twice a year for information about changes in the baby s health. Participants may also be asked permission to perform new tests developed by researchers.
Umbilical cord blood is a source of hematopoietic stem cells (HSCs) for transplantation or gene therapy. Our goal is to procure umbilical cord blood (UCB) from newborns at risk for sickle cell disease, sickle cell trait, and related disorders as well as normal newborns, for our controls, in order to develop methods for processing and cryopreservation of umbilical cord blood HSCs for use in future clinical transplantation or gene therapy. In order to carry out our methods development research umbilical cord blood units will be collected from an indefinite number of subjects until 30 cord blood units from newborns with sickle cell disease have been cryopreserved. These units will be stored for future gene therapy. Maternal subjects will have been identified as being at risk to have an infant with sickle cell disease, will be between the ages of 18 and 45, and will meet specified medical history criteria. The cord blood units will be tested for transfusion transmissible viruses, infectious disease markers, Human Leukocyte Antigen (HLA) typing, Hemoglobin genotyping, and enumeration of progenitor cells. The umbilical cord blood units will be used for the developmental research on processing/cryopreservation methods but, once processed and stored, may also be identified for future clinical use or for basic or translational research by NIH investigators. This study will be a multisite collaboration with Washington metropolitan area hospitals.

|Eligibility Criteria ICMJE||
Pregnant women who are at risk of having an infant with sickle cell anemia (HbSS), as well as woman who are not at risk and wish to serve as control subjects, will be identified and referred by their health care providers or will be self-referred.
Maternal subjects must be between 18 and 45 years old, may be in their first or subsequent pregnancy, and must be able to provide informed consent.
The maternal subject will not be eligible for study if she is known to be positive for one or more of the following diseases transmissible by blood: HIV, hepatitis B, hepatitis C, or HTLV; is unable to give informed consent; or is known to have a fetus with a significant congenital anomaly.
Subjects may be excluded at the time of delivery if the attending physician or collection staff, due to unanticipated obstetrical complications, deems cord blood collection inadvisable.
