Brief Summary:

Background:

  • National Institutes of Health (NIH) researchers have been studying immune cells (white blood cells) to better understand how the human body s defense system works and adjusts or regulates itself, and how changes in this system can make a person sick.
  • To study the cells of patients who have problems with their immune systems, researchers would like to collect samples of skin cells from patients with immune system disorders and compare them with skin cells taken from healthy volunteers. By studying these cells, researchers hope to determine whether these cells can be modified to create a new kind of personalized gene therapy that would attempt to cure immune diseases in the future.

Objectives:

  • To obtain skin cells from patients with immune system disorders and from healthy volunteers for research and comparison purposes.

Eligibility:

  • Patients between the ages of 2 and 85 who have immune system disorders.
  • Healthy volunteers between the ages of 18 and 85.
  • Both groups will be selected from the eligible participants of existing NIH studies into immune system disorders.

Design:

  • Researchers may take up to two biopsies from participants arms, legs, abdomen, or back.
  • The biopsy site will be numbed with local anesthetic and cleaned before the sample is taken.
  • The punch skin biopsy needle will be inserted into the skin and rotated to remove a small circle of skin (approximately 1/4 to 3/8 of an inch across). The area will be closed with bandages or stitches, and then covered with a dressing. Any stitches will be removed in 7 to 10 days.
  • Tissue samples collected in the study will be stored for future research.

Primary Immunodeficiency DOCK8 Virus Susceptibility

Detailed Description:

This protocol is designed as an adjunct to other National Institutes of Health (NIH) IRB approved protocols that allow for genetic testing, which may include those that are screening protocols for patients with rare primary immunodeficiency or immunodysregulation disorders. Patients deemed of sufficient research interest after review of outside medical records, clinical evaluation, and testing, may be invited to participate in this study. Healthy volunteers and relatives of patients will also be invited to participate as a source of control samples for research testing. After consent and enrollment into this study, skin punch biopsies will be obtained to establish dermal fibroblast cell lines for research studies directed at understanding the genetic and biochemical bases of these diseases. Cell lines will also be used to investigate the utility of induced pluripotent stem cells (iPS) for lymphocyte derivation and targeted gene correction. The nasal epithelial scrapings will be used for research purposes to grow out primary nasal respiratory epithelial cell lines. These cell lines will be used for functional studies by testing virus replication in them. These functional studies will allow us to identify new primary immunodeficiencies that may present primarily as recurrent or persistent lower respiratory tract virus infections. Results with the potential to impact medical care will be relayed to the referring physicians and where applicable patients will be referred to other appropriate NIH protocols for additional clinical evaluation andtreatment.

The study will enroll up to 200 patients and healthy volunteers over the next 15 years.

Study Type : Observational
Estimated Enrollment : 200 participants
Observational Model: Cohort
Time Perspective: Cross-Sectional
Official Title: Establishing Fibroblast-derived Cell Lines From Skin/Tissue Biopsies of Patients With Immunodeficiency or Immunodysregulation Disorders
Actual Study Start Date : June 10, 2009


Group/Cohort
Healthy Volunteers
Up to 50 subjects as healthy controls
Immunodeficiency
Up to 150 subjects with poorly defined, rare inherited immunodeficiency or immunodysregulation disorders



Primary Outcome Measures :
  1. Generate fibroblast, dermal, or other skin-resident cell lines [ Time Frame: Over the lifetime of the study ]
    Obtain skin punch biopsies to generate fibroblast, dermal, or other skin-resident cell lines in patients who previously underwent HSCT. Cells may also be used for somatic cell hybridization, cell complementation, assessing fibroblast-specific innate immune responses, or other genetic techniques.

Ages Eligible for Study:   2 Years to 85 Years   (Child, Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population
Up to 150 patients with poorly defined, rare inherited immunodeficiency or immunodysregulation disorders, and up to 50 healthy volunteers as controls.

Criteria
  • INCLUSION CRITERIA:

Patients:

  1. To be enrolled in this study, a patient must be >=2 years of age but not >85 years of age,
  2. have a known diagnosis of primary immunodeficiency or immunodysregulation (or be a blood relative of such as patient),
  3. be concurrently enrolled on an NIH IRB approved NIAID protocol that includes genetic testing for disease of the immune system, such as but not limited to 05-I-0213 or 06-I-0015

Patient Relative: To be enrolled in this study, a patient relative must be:

  1. A biological relative of a participant being studied under this protocol. Relatives may be biological mother, father, sibling, children, grandparents, aunts, uncles and first cousins.

    a. A minor relative of the proban participant must demonstrate that they are asymptomatic carriers or are at risk for the disease

  2. be concurrently enrolled on an NIH IRB approved protocol that includes genetic testing for disease of the immune system, such as but not limited to 05-I-0213 or 06-I-0015.
  3. Greater than or equal to 8 years of age but not greater than 85 years of age,

Healthy Volunteers:

To be enrolled in this study, a normal volunteer must fulfill all of the following criteria:

  1. Be enrolled on protocol 05-I-0213.
  2. Be a healthy adult of either sex and between ages of 18 years and 85 years

EXCLUSION CRITERIA:

Patients or the Patient Relative are not eligible to be in this trial if::
