Brief Summary:
Individuals with a past diagnosis of severe combined immune deficiency (including many cases of "leaky SCID", Omenn syndrome, and reticular dysgenesis) who have undergone blood and marrow transplant, gene therapy, or enzyme replacement in the past may be eligible for this study. The purpose of study is to look backwards at what has already been done in the. Over 800 patients with SCID are expected to be enrolled, making this one of the largest studies ever to describe outcomes for patients with SCID treated at many different hospitals around North America.

Condition or disease
SCID ADA-SCID XSCID Leaky SCID Omenn Syndrome Reticular Dysgenesis

Detailed Description:
One of the most important components of this study is the "cross sectional" aspect. Patients who have received their treatments (BMT, gene therapy, enzyme replacement) many years ago are asked to come back to the hospital where they were treated. During this visit, additional research bloodwork is drawn, and information is gathered regarding long-term transplant outcomes such as infections, graft-versus-host disease, autoimmune diseases, and quality of life. This will allow PIDTC researchers to better understand long-term outcomes from procedures that occurred many years ago (sometimes over 30 years ago). This will help researchers to best design new treatments and clinical trials in the future for children with SCID.

Criteria

Inclusion Criteria:

Strata A, B, and C (Part 1 - Retrospective Study)-

  • Individuals with Severe Combined Immune Deficiency (SCID) diagnosis who:

    --were treated at a location participating in this consortium from 1968 until present, and

    --are not enrolled in RDCRN PIDTC-6901 (ClinicalTrials.gov ID: NCT01186913).

  • Subjects who received HCT/GT/ERT prior to the present date are eligible for the retrospective study. The enrollment criteria for subjects who died prior to definitive therapy are the same as for Strata A, B and C.

Stratum A, Typical SCID:

  • Individuals who meet the following inclusion criteria and who received HCT are eligible for enrollment into Stratum A of the study:

    • Absence or very low number of T cells (CD3 T cells < 300/microliter), and no or very low T cell function (< 10% of lower limit of normal) as measured by response to phytohemagglutinin (PHA) or cells of maternal origin present.
    • If maternal cells are present but the patient does not meet criteria for very low T cell function as defined, the assigned reviewers for the potential subject, and if necessary, the full PID-SCID RP will review the laboratory report to determine if criteria of maternal engraftment are met for Protocol 6902.
    • Laboratory report of testing for maternal engraftment is required, for evaluation by the PID-SCID RP.

Stratum B, Leaky SCID, Omenn Syndrome, Reticular Dysgenesis:

Individuals who meet the following criteria are eligible for enrollment into Stratum B of the study:

Leaky SCID-

  • Maternal lymphocytes tested for and not detected and,

  • Either one or both of the following (a,b):
