About this study

Official title: Genetic Studies of the X-Linked Lymphoproliferative Disease

This study will study the effects of the gene on the X chromosome that is associated with X-linked lymphoproliferative disease (XLPD)-an inherited disease affecting the immune system-on the function of the immune system. XLPD has been linked to an abnormality in a specific region of the X chromosome (one of 23 chromosome pairs that contain the genes that determine a person's hereditary makeup). The disease may develop after infection with the Epstein-Barr virus (EBV). EBV affects more than 95 percent of people in the United States. It usually does not cause any symptoms in children. In adolescents and adults, however, EBV can cause infectious mononucleosis and sometimes lymphoproliferative disease, such as XLPD. In these diseases lymph tissues, such as lymph nodes, may become enlarged and immune function (infection-fighting ability) impaired. This study will compare DNA from patients with XLPD with that of their unaffected relatives, of patients with other lymphoproliferative diseases and of normal controls.

Patients of any age with XLPD, their unaffected relatives 18 years of age and older, and patients with other lymphoproliferative diseases may participate in this study.

Blood samples will be collected from all participants to study the effects of the gene on the X chromosome that appears to be abnormal in XLPD on the function of the immune system. In a 6-week period, no more than 100 milliliters (about 7 tablespoons) of blood will be drawn from adults and no more than 1 ml (1/6 teaspoon) of blood per pound of body weight from children. Blood from patients with XLPD and their relatives will also be tested for HLA type (similar to blood type testing) and the ability of HLA-matched cells from patients and relatives to interact will be examined.

Read the detailed description

Males with the X-linked ymphoproliferative disease (XLPD) have a marked susceptibility to Epstein-Barr virus (EBV) disease. These boys develop very severe disease associated with infectious mononucleosis; others develop hypogammaglobulinemia or B cell lymphomas. Recent studies have linked the disease to a region of the X-chromosome. The purpose of this study is to determine the function of the gene responsible for XLPD. Blood samples or discarded tissues (e.g. previous biopsy or autopsy material) from patients with XLPD and their relatives will be analyzed to determine the precise genetic defect associated with the disease. Blood samples or discarded tissues from other patients with EBV-associated lymphoproliferative diseases and blood samples from normal individuals will be obtained to serve as controls. Knowledge gained from this study should provide important insights into the immunologic control of EBV lymphoproliferative disease associated with congenital or acquired immunodeficiency. In addition, identification of the molecular mechanisms for these diseases may provide clues to other EBV-associated diseases including nasopharyngeal carcinoma, Burkitt lymphoma, and Hodgkin's disease.

Questions about this trial

What is this clinical trial studying?

An observational study of X-Linked Lymphoproliferative Disease and Lymphoproliferative Disease, run by National Institute of Allergy and Infectious Diseases (NIAID) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00359411, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Jul 2017.
