PRIMARY IMMUNODEFICIENCY PROGRAM

PROTOCOL TITLE: INVESTIGATING THE MECHANISTIC BIOLOGY OF PRIMARY IMMUNODEFICIENCY DISORDERS

This study investigates novel forms of primary immunodeficiency (PID) and to better define the natural history of both new and previously described forms of PID, including severe combined immunodeficiency (SCID), combined immunodeficiency, natural killer (NK) cell deficiency, and other disorders. Patients with clinical and/or laboratory evidence of PID will be recruited at Children's National and NIAID, and will provide one or more blood donations during the course of the study to enable immunologic and genetic investigations of immune pathways contributing to PIDs. These subjects will also be followed clinically to longitudinally assess the natural history of novel and known PIDs. Subjects will be followed over time with regard to their immunologic phenotype, clinical disease (including incidence of infections, autoimmune phenomena, allergic disease, or malignancies), and response to both preventative and definitive therapies. Biological relatives who do not have PID and healthy adult volunteers will also be eligible to serve as controls for this study.
