This study will compare the health and well being of children treated with a modified stem cell transplantation procedure for chronic granulomatous disease (CGD) with that of children receiving standard of care treatment. CGD is an inherited disorder of neutrophils-a type of infection-fighting white blood cell-that leaves patients vulnerable to life-threatening infections. Standard treatment with antibiotics, and sometimes surgery, is not always successful, and patients with persisting infections have a poor long-term prognosis.
Transplantation of donated stem cells (cells produced by the bone marrow that mature into white and red blood cells and platelets) can improve immune function in patients with CGD and possibly cure the disease. However, this procedure carries a significant risk of death, because it requires complete suppression of the immune system with high-dose chemotherapy. In addition, lymphocytes-another type of infection-fighting white blood cell-from the donor may cause what is called graft versus host disease (GvHD), in which the donor cells 'see' patient's cells as foreign and mount an immune response to reject them. To try to reduce these risks, patients in this study will be given low-dose chemotherapy that is easier for the body to tolerate and involves a shorter period of complete immune suppression. Also, the donor's lymphocytes will be removed from the rest of the stem cells to be transplanted, reducing the risk of GvHD.
Patients with CGD between 2 and 17 years of age who 1) are currently free of active infection, and 2) have a history of at least one life-threatening infection or a family member with CGD and a history of at least one life-threatening infection, and 3) a family member that is a suitable donor may be eligible for this study. Candidates will have a medical history, physical examination and blood tests, lung and heart function tests, x-rays or CT scans of the body, and dental and eye examinations. They will fill out questionnaires that measure emotional well being, quality of life, and intelligence (ability to learn and understand).
Stem cells will be collected from both the patient and donor. To do this, the hormone G-CSF will be injected under the skin for several days to move stem cells from the bone marrow to the bloodstream. Then, the stem cells will be collected by apheresis. In this procedure the blood is drawn through a needle placed in one arm and pumped into a machine where the required cells are separated out and removed. Then, the rest of the blood is returned through a needle in the other arm.
Several days before the transplant procedure, patients will start a 'conditioning regimen' of chemotherapy with cyclophosphamide, fludarabine and Campath 1H. When the conditioning therapy is completed, the donor's stem cells will be infused. To help prevent rejection of donor cells, cyclosporine will be given by mouth or by vein starting 1 month after the transplant procedure.
The average hospital stay for stem cell transplantation is 21 days. After discharge, patients will return to the NIH clinic for follow-up clinic visits weekly or twice weekly for 2 to 3 months. These visits will include a symptom check, physical examination and blood tests. Subsequent clinic visits will be scheduled 1 to 3 times a year for at least 5 years.
Chronic Granulomatous Disease (CGD) is one of several inherited disorders of leukocyte function. Patients are profoundly immunocompromised and plagued early in life with recurrent and often life threatening infections. Allogeneic stem cell transplantation significantly improves immune function in patients with CGD. The primary objective of this study is to investigate efficacy of a novel approach to allogeneic stem cell transplantation, which is designed to promote partial or complete donor stem cell engraftment (hematopoietic chimerism) with reduced transplant related morbidity and mortality. In an attempt to reduce toxicity from pre-transplant bone marrow conditioning, a highly immunosuppressive, low intensity bone marrow conditioning regimen will be used. Patients will be transplanted with peripheral blood stem cells from an HLA identical family member. The graft will be enriched for hematopoietic stem cells in an attempt to decrease the risk of graft versus host disease. Donor T-cells will be infused at various time points following the transplant to augment donor hematopoietic chimerism and aid in immune reconstitution. Patients treated with this approach will be compared to patients who are considered transplant-eligible but lack an HLA identical family member. These patients will be treated using the current standard of care. The primary end points of this study are to demonstrate reduced incidence of CGD-like infections in the transplanted patients compared to the controls (efficacy) with acceptable incidence of acute and chronic graft versus host disease and transplant related mortality (safety). Long term follow up data from transplanted patients and concurrent controls will be analyzed to confirm the association between establishment of hematopoietic chimerism and clinical benefit.

The following conditions must be met before a patient may be enrolled in the study:
Patients ages 2 to 17 years; minimum weight of 12 kg.
DHR proven chronic granulomatous disease with gp91 phox or p22 phox deficiency.
History of at least one life-threatening infection (defined as any infection requiring treatment with intravenous antibiotic therapy) or a family member with CGD and a history of life-threatening infection.
Free of active infection.
Patients with consenting HLA-matched related donors that meet donor selection criteria (test patients), or patients without an eligible HLA-matched related donor (control patients). Patients with eligible donors who choose not to undergo stem cell transplantation or patients with eligible but non-consenting donors may be enrolled in the control arm of the study. Patients enrolled in the control arm who complete a 24 month follow-up period may enroll in the transplant arm should an eligible, consenting donor become available.
Patients with adequate organ function as measured by:
Cardiac: Asymptomatic or, if symptomatic, then left ventricular ejection fraction at rest must be greater than 35%.
Hepatic: SGOT within 4 times normal range and total bilirubin less than 2mg/dL.
Renal: Creatinine clearance greater than or equal to 50 mL/min/ 1.73m(2). A maximum age adjusted serum creatinine will be used for patients who are unable to provide an accurate 24 hour urine collection. For children less than or equal to 5 years of age, the maximum serum creatinine (mg/dl) is 0.8; for children whose age is greater than 5 to less than or equal to 10, the maximum serum creatinine (mg/dl) is 1.0; for children whose age is greater than 10 to less than or equal to age 15, the maximum serum creatinine (mg/dl) is 1.2; and for children whose age is greater than 15, the maximum serum creatinine (mg/dl) is 1.5.
Pulmonary: DLCO (diffusion capacity) and FEV1 greater than 45 percent of predicted (corrected for hemoglobin). Minors in whom pulmonary function tests are not possible will be evaluated for significant pulmonary dysfunction by a pulmonary consultant.
Written informed consent/assent conforming to institutional guidelines obtained from patient and parent.
Absence of co-existing medical problems that would significantly increase the risk of a transplant procedure in the judgment of the principal investigator.

Female x-linked CGD carriers must have greater than 30 percent normal neutrophils.
If donor is a sibling who is a minor, he/ she is the oldest eligible sibling and no adult siblings are eligible donors.
Written informed consent from donor. Donors who are minors will be evaluated by a social worker, psychologist or psychiatrist prior to the assent process to determine willingness to participate. If willingness to participate has been confirmed, informed consent will be obtained from adult parent or legal guardian. Informed assent will be obtained from minor donor in the presence of a third party who will assess comprehension and voluntary participation.
