Interferon Gamma to Treat Leukocyte Adhesion Deficiency Type I
Interferon Gamma Administration in Leukocyte Adhesion Deficiency Type I
This study will evaluate the safety and effectiveness of the drug, interferon gamma, in treating leukocyte adhesion deficiency type I (LAD I). Patients with this inherited immune disorder do not have enough proteins called adhesion molecules on their infection-fighting white blood cells, impairing the ability of these cells to get to the site of infection. As a result, patients have recurrent infections of soft tissues, such as the skin, gums and gastrointestinal tract, and poor wound healing. Infants with severe LAD I often die from multiple infections. Interferon gamma may increase the number of adhesion molecules on white blood cells, and thus improve their function.
Patients with LAD I who weigh more than 13 kilograms (28.5 pounds) may be eligible for this study. Candidates will have personal and family medical histories taken, a physical examination, blood and urine tests and a chest X-ray or computed tomography (CT) scan.
Participants will receive injections of interferon gamma under the skin 3 times a week for 3 months. Adult patients will be taught how to give their own injections (similar to insulin injections for diabetes) and parents will be taught how to administer the shots to their child. Blood samples, usually be between 30 to 90 milliliters (2 to 6 tablespoons), will be drawn just before starting medication and again 1 day, 1 week, 1 month, 3 months and 4 months after therapy begins. At these same time intervals, patients will provide a salt-water mouth rinse specimen, which will be tested for changes in the number of white blood cells during interferon gamma treatment.
Patients will be admitted to the NIH Clinical Center for inpatient evaluations at the start of therapy and again after 1 week, 1month, 3 months and 4 months. The initial screening visit will take a few days and subsequent visits will take 1 to 2 days.

Patients should be without serious, ongoing, uncontrolled infections.
Adequate hematopoietic, renal and hepatic function, defined as:
Absolute neutrophil count greater than or equal to 1500/microL;
Hemoglobin greater than or equal to 7g/dL (post transfusion or erythropoeitin);
Platelet count greater than or equal to 100,000/microL;

Pregnant or lactating women.
Surgery during the two weeks prior to the start of IFN-gamma dosing.
Concurrent use of systemic corticosteroids, except for physiologic replacement.
Exposure to any investigational drug within four weeks prior to the start of dosing.
Any other major illness which, in the investigator's judgement, may substantially increase the risk associated with the patients participation in this study.
