National Institute of Allergy and Infectious Diseases (NIAID)
Individuals with Primary Immune Deficiency (PID) may develop severe, life-threatening infections as a result of inherited defects in the genes that normally instruct blood-forming cells to develop and to fight infections. PID diseases include Severe Combined Immune Deficiency (SCID), leaky SCID, Omenn syndrome (OS), and Reticular Dysgenesis (RD). PIDs may be treated by transplantation of bone marrow stem cells from a healthy person or, in some cases, by enzyme replacement or by gene therapy. Patients with SCID were among the first to receive bone marrow stem cell (also called hematopoietic cells) transplantation (HCT) more than 40 years ago, and HCT is the standard treatment today for this group of diseases. Since PID diseases are rare, there are not enough patients at any single center to determine the full range of causes, natural history, or best methods of treatment. For this research study many PID centers across North America have organized into the Primary Immune Deficiency Treatment Consortium (PIDTC) to pool their experience and study PIDs together. The overall goal of this study is the prospective evaluation of children with SCID and related disorders who are treated under a variety of protocols at participating institutions. The study aims to identify variables contributing to the best outcomes for HCT.

Estimated Study Completion Date: August 2019
Estimated Primary Completion Date: August 2019 (Final data collection date for primary outcome measure)
Classic SCID (Stratum A)
Patients with classic SCID after allogeneic hematopoietic stem cell transplantation
Leaky SCID, Omenn syndrome, or RS (Stratum B)
Patients with leaky SCID, Omenn syndrome, or Reticular Dysgenesis (RS) after allogeneic hematopoietic stem cell transplantation
ADA Deficiency or XSCID treated with PEG-ADA (Stratum C)
Patients with ADA Deficiency or XSCID who are treated with PEG-ADA (patients with ADA Deficiency) or patients who are treated with gene therapy (ADA Deficiency or XSCID)

Detailed Description:

This study follows participants with SCID prospectively, meaning the study enrolls participants where there is a plan to receive a blood and marrow transplant, enzyme therapy, or gene therapy in the future. Participants are then followed according to a schedule set out by the study protocol after the procedure. There are no experimental therapies on this study.

The study plans to enroll over 200 participants with SCID. By studying new participants undergoing treatment for SCID, the goal is to learn more about: (1) outcomes from the treatment of SCID in the modern era of medicine (2) what factors lead to the best long-term outcomes, such as best donor, conditioning regimen, timing of transplant, etc., and (3) what impact newborn screening and the early diagnosis of SCID has had on the long-term outcomes following BMT or gene therapy. Information is also being gathered on how and when the immune system recovers after BMT, quality of life for long-term survivors, and about whether children develop normally after treatment.

This natural history study is the largest coordinated prospective study of participants with SCID ever performed. Information that we will learn, both now and in the future, will help doctors and other health professionals to better treat children with SCID.

Sampling Method:   Non-Probability Sample
Study Population
Patients with diagnosis of SCID or SCID variants treated at Consortium Centers from 1968-2010

Subjects who meet the following inclusion criteria and the intention is to treat with allogeneic hematopoietic cell transplant (HCT) are eligible for enrollment into Stratum A (Classic SCID):

  • Absence or very low number (<300 /µL) of CD3+T cells, AND
  • No or very low (<10% of lower limit of normal) T cell function (as measured by response to phytohemagglutinin (HLA) OR

    • T cells of maternal origin present.
    • Stratum B, Leaky SCID, Omenn Syndrome, Reticular Dysgenesis.

Subjects who meet the following criteria and the intention is to treat with HCT are eligible for enrollment into Stratum B:
