Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: Allogenic hematopoietic cell transplantation (HCT) is a procedure in which a person gets stem cells from a donor in order to treat their disease. Researchers want to collect samples from people who have had or will have HCT. They will perform tests on the samples to study the immune system and its response to infections and disease. Objective: To collect biological samples from people who have had or are planning to have HCT to treat primary immunodeficiencies, blood cancers, or disorders of T-cell proliferation and/or dysregulation. Eligibility: People age 8 years and older who have undergone or are planning to undergo HCT. Design: Participants will be screened with: Medical history Medical chart review Physical exam Blood tests. Participants may give blood and urine samples. Participants may have a skin biopsy. Participants may undergo apheresis. For this, a needle will be placed into an arm vein to take blood. A machine divides the whole blood into parts. The sample cells are taken out and the rest of the blood is returned through a second needle in the other arm. Participants may have a bone marrow aspiration and biopsy. For this, the hipbone will be numbed. A needle will be put into the hipbone. Bone marrow will be taken out through the needle. Participants may have a tumor or other abnormal tissue biopsy. For this, a tissue sample is obtained using a needle and syringe. They will sign a separate consent form. They may have a body scan or ultrasound to help locate the tumor during the biopsy. Participation lasts for as long as participants choose to give samples.
