Summary

This protocol is designed for a single specific patient. It uses busulfan as a conditioning agent in a second stem cell transplant procedure for a patient with chronic granulomatous disease (CGD), a disorder in which a certain type of white cells, called myeloid cells, do not function properly. This causes increased risk of serious bacterial and fungal infections that can lead to organ dysfunction, such as kidney disease, as well as formation of granulomas-non-cancerous masses that can cause obstructions in the esophagus, stomach, and intestines, and block urine flow from the kidneys and bladder.). The child in this study has previously undergone a stem cell transplant to treat CGD, and, as a result, he is now producing normal lymphocytes (another type of white cell). However, the myeloid cells from the donor did not engraft successfully, and the patient is still producing his own defective myeloid cells. In this study, the child will undergo a second stem cell transplant in combination with busulfan, a drug that targets myeloid cells, killing them to make way for healthy, donated myeloid cells.

Treatment includes the following procedures:

* Medical evaluation to confirm that the patient is healthy enough to undergo the transplantation
* Treatment with busulfan, injected through the patient's central venous line
* Stem cell transplantation through the central venous line
* Blood tests on days 25, 56, and 91 after the transplant to assess how many cells are of donor origin
* Bone marrow aspiration on day 100, and then at 12, 24, and 36 months to assess how many cells are of donor origin
* Pulmonary function (breathing) test at 12 and 24 months
* Physical examination and blood tests, weekly or twice weekly for the first 2 to 3 months and at 4, 6, 12, 18, 24, 36, 48, and 60 months after transplant
* Treatment for graft-versus-host disease (GVHD), if this complication develops. GVHD is the attack of lymphocytes from the donor against the patient's own cells. This is good if it is against abnormal cells, but bad if serious damage occurs to the patient's vital organs. GVHD is treated with steroids and cyclosporine, and possibly other drugs if needed.
