 Allogeneic transplant using HLA matched donors, both related and unrelated, has proven curative for patients with various immunodeficiencies, including those with ongoing infections. However donor availability remains a limiting factor in the application of this treatment modality. The use of haploidentical donors has in the past been fraught with a greater rate of complications related to both higher rates of GvHD and delayed immunorecovery. Newer transplant regimens appear to have diminished these risks and improved outcomes. We propose using a subablative conditioning regimen followed by post-transplant cyclophosphamide for patients with CGD who do not have an HLA matched donor but whose circumstances necessitate the use of a potentially curative, albeit high-risk treatment modality.
