Brief Summary

Background: Blood stem cells in the bone marrow make all the cells to normally defend a body against disease. Allogeneic blood or marrow transplant is when these stem cells are transferred from one person to another. Researchers think this treatment can provide a new, healthy immune system to correct T-cell problems in some people. Objective: To see if allogeneic blood or bone marrow transplant is safe and effective in treating people with T-cell problems. Eligibility: Donors: Healthy people ages 4 and older Recipients: People the same age with abnormal T-cell function causing health problems Design: All participants will be screened with:

  • Medical history
  • Physical exam
  • Blood, heart, and urine tests Donors will also have an electrocardiogram and chest x-ray. They may have veins tested or a pre-anesthesia test. Recipients will also have lung tests. Some participants will have scans and/or bone marrow collected by needle in the hip bones. Donors will learn about medicines and activities to avoid and repeat some screening tests. Some donors will stay in the hospital overnight and have bone marrow collected with anesthesia. Other donors will get shots for several days to stimulate cells. They will have blood removed by plastic tube (IV) in an arm vein. A machine will remove stem cells and return the rest of the blood to the other arm. Recipients will have:
  • More bone marrow and a small fragment of bone removed
  • Dental, diet, and social worker consultations
  • Scans
  • Chemotherapy and antibody therapy for 2 weeks
  • Catheter inserted in a chest or neck vein to receive donor stem cells
  • A hospital stay for several weeks with more medicines and procedures
  • Multiple follow-up visits

  • Identified adenosine deaminase 2 (ADA2) deficiency (biallelic mutations in CECR1 (ADA2) and/or phenotypically with low ADA2 level) leading to neutropenia requiring chronic granulocyte colony-stimulating factor (GCSF) therapy or to transfusion-dependent anemia or thrombocytopenia
  • T-cell infiltration of liver, spleen, lymph nodes, marrow, lungs, gut, or other organs by T cells, as evidenced by laboratory, radiographic, and/or anatomic pathology evaluation, resulting in organ dysfunction and/or organomegaly
  • Latent herpesvirus infection in T lymphocytes
  • History of or active evidence of hemophagocytic lymphohistiocytosis (HLH)
  • Recurrent or prolonged fevers attributed to immune dysregulation

HLA typing of potential donors and/or mutation testing does not need to be completed for eligibility.
  • Adequate end-organ function, as measured by:
  • Left ventricular ejection fraction (LVEF) greater than or equal to 40% by 2-dimensional (2D) echocardiogram (ECHO) or left ventricular shortening fraction greater than or equal to 20% by ECHO for subjects receiving reduced-intensity conditioning (RIC), or LVEF greater than or equal to 30% if the subject has radiologic evidence of aortic, renal, or coronary artery vasculitis. LVEF greater than or equal to 30% for subjects receiving immunosuppression-only conditioning (IOC).

  • Lack of adequate central venous access potential
  • Age greater than or equal to 4 years
  • Related donor deemed suitable and eligible, and willing to donate, per clinical evaluations who are additionally willing to donate blood, urine, and marrow specimens for research. Related donors will be evaluated in accordance with existing Standard Policies and Procedures for determination of eligibility and suitability for clinical donation. Note that participation in this study is offered to all related donors, but is not required for clinical donation, so it is possible that not all related donors will enroll onto this study.
  • None
  • Unrelated donors will be evaluated in accordance with existing National Marrow Donor Program (NMDP) Standard Policies and Procedures, available at: http://bethematch.org/About-Us/Global- transplant-network/Standards/, except for the additional requirement of EBV serostatus testing for clinical purposes of donor selection. Note that participation in this study is offered to all unrelated donors but not required for clinical donation, so it is possible that not all unrelated donors will enroll on this study. Unrelated donors only enroll if they contribute research specimens, which is optional.
  • Unrelated donors: failure to qualify as a National Marrow Donor Program (NMDP) donor per current NMDP Standards, available at: http://bethematch.org/About-Us/Global-transplant-network/Standards/. Exceptions to donor eligibility (e.g. foreign travel, tattoos) do not automatically exclude the donor and will be reviewed by the PI.
