All conditioning regimens were myeloablative. Engraftment days, complications, and survival data were recorded. As follow-up was short, we recorded only 6-minute walk test distance before versus after HSCT.Results: The patients underwent transplantation at a median of 6-year postdiagnosis. All were engrafted and had a full or mixed chimerism. Enzyme levels were within normal ranges. Walking tests of all evaluable patients improved at a median 9-month follow-up.Conclusion: HSCT aims to improve the disease and provides a permanent solution at the enzyme level, eliminating ERT. Our study showed that HSCT, a less expensive and permanent treatment option, should be offered to patients with MPS VI.<\/jats:p>","DOI":"10.3345\/cep.2024.02033","type":"journal-article","created":{"date-parts":[[2025,3,11]],"date-time":"2025-03-11T03:07:06Z","timestamp":1741662426000},"page":"601-607","update-policy":"https:\/\/doi.org\/10.3345\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Hematopoietic
