Scope and Burden of Non-Standard of Care Hematopoietic Stem Cell Transplantation in Pediatric Leukodystrophy Patients.

Abstract：

:Inherited leukodystrophies are a group of diseases affecting central nervous system myelin that lead to death or significant health problems. Although for most leukodystrophies there are no curative treatments, for a handful of diseases hematopoietic stem cell transplantation (HSCT; bone marrow transplant) can stop disease progression, and if initiated in a timely fashion, prevent many or all neurologic and other systems involvement. However, HSCT is a complex procedure with significant morbidity and mortality risks. The study goal was to determine whether HSCT was being more widely used outside of those leukodystrophies for which HSCT is typically employed. The authors conducted a 2-year retrospective review of HSCT performed across the United States in 51 children's hospitals that are part of the Pediatric Health Information System. The authors screened for 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10) codes for leukodystrophies in which HSCT is "nonstandard," including sphingolipidoses, Fabry disease, Gaucher disease, and Niemann-Pick disease, and excluded patients who had ICD-10 codes for leukodystrophies that are HSCT candidates, specifically X-linked adrenoleukodystrophy, metachromatic leukodystrophy, Krabbe disease, and Hurler disease. The authors identified 91 patients (from a total cohort of 937) with one of the nonstandard leukodystrophies who had HSCT. HSCT was performed at 20 of the hospitals, with the majority performed at only 6 hospitals. Average costs ($786 846) per patient were more than 6 times higher than patients who did not have HSCT. The data show that an unexpectedly large number of leukodystrophy patients are receiving transplants for conditions in which HSCT is not typically used, and which are associated with high medical costs.
