Chronic granulomatous disease is a primary immunodeficiency caused by mutations in any one of the five components of the NADPH oxidase in phagocytic leucocytes. This causes impaired microbial killing, which leads to severe life-threatening bacterial and fungal infections. Currently, allogenic hematopoietic stem cell transplantation (HSCT) is the only curative treatment for chronic granulomatous disease, although gene therapy may provide a new therapeutic option for the treatment of patients with CGD. Haploidentical HSCT provides a potentially curative treatment option for patients who lack a suitably HLA-matched donor, but only a few cases have been reported in the literature. Herein, we report a boy with X-linked chronic granulomatous disease treated successfully by haploidentical HSCT with post-transplant cyclophosphamide using a treosulfan-based conditioning regimen.
