AI Article Synopsis

  • Hurler syndrome causes severe health issues in children and often leads to early death, leading researchers to evaluate the long-term effects of umbilical cord blood transplantation on affected patients.
  • The study analyzed 25 patients who had the transplantation between 1995 and 2006, with 19 of them followed for at least 5 years, assessing various health outcomes and development.
  • Results showed an 80% survival rate, improvement in overall health, and developmental gains, though some patients still faced challenges like hearing and vision issues, with significant improvements noted in bodily growth and neurological health over time.

Article Abstract

Objectives: Hurler syndrome is characterized by progressive multisystem deterioration leading to early death in childhood. This prospective study evaluated the long-term outcomes of patients with Hurler syndrome who underwent umbilical cord blood transplantation from unrelated donors.

Study Design: Only patients with Hurler syndrome who underwent umbilical cord blood transplantation between December 1995 and March 2006 (n = 25) and who were followed for at least 5 years (n = 19) were included in the analysis. The patients were longitudinally evaluated by a multidisciplinary team of specialists following a standardized protocol.

Results: Median age at transplantation was 15.9 months (range 2.1-35), and patients were followed up until a median age of 10.1 years (range 7.2-14.9). Overall survival was 80%. All successfully transplanted patients achieved full donor chimerism and normal enzyme levels, and all children continue to make gains in development. Gross motor function was the most affected area. Vision and hearing were compromised in a minority of the patients, with some requiring corneal transplant or hearing aids. Cardiopulmonary function improved. Some children required orthopedic surgery, but severe complications were prevented in most patients. Although longitudinal growth was lower than that of unaffected children, it was considerably higher than expected from the natural course of the disease. Head circumference normalized. Hydrocephalus was not observed at longer follow-up, and cerebral atrophy decreased over time.

Conclusions: In this descriptive study of children with Hurler syndrome, unrelated umbilical cord blood transplantation was associated with improved somatic disease and neurodevelopment.

Background: Hematopoietic cell transplantation (HCT) is the standard of care treatment for children with Hurler syndrome (HS). This study describes the impact of newborn screening (NBS) on HCT outcomes for these patients.

Methods: Retrospective study of HS patients diagnosed through NBS and referred to Duke from 2017 to 2023.

Hurler-Scheie syndrome (MPS IH/S), also known as mucopolysaccharidosis type I-H/S (MPS IH/S), is a lysosomal storage disorder caused by deficiency of the enzyme alpha-L-iduronidase (IDUA) leading to the accumulation of glycosaminoglycans (GAGs) in various tissues, resulting in a wide range of symptoms affecting different organ systems. Postgenomic omics technologies offer the promise to understand the changes in proteome, phosphoproteome, and phosphorylation-based signaling in MPS IH/S. Accordingly, we report here a large dataset and the proteomic and phosphoproteomic analyses of fibroblasts derived from patients with MPS IH/S ( = 8) and healthy individuals ( = 8).

Background: Mucopolysaccharidosis type I is a lysosomal storage disease resulting from a deficiency in alpha-L-iduronidase (IDUA), which causes the accumulation of partially degraded dermatan sulfate and heparan sulfate. This retrospective study, spanning eight years, analyzed data from 45 MPSI patients. The report aimed to explore the potential origin of the p.

Enzymopathy disorders are the result of missing or defective enzymes. Among these enzymopathies, mucopolysaccharidosis type I is a rare genetic lysosomal storage disorder caused by mutations in the gene encoding alpha-L-iduronidase (IDUA), which ultimately causes toxic buildup of glycosaminoglycans (GAGs). There is currently no cure and standard treatments provide insufficient relief to the skeletal structure and central nervous system (CNS).

This case report details a 12-year-old male diagnosed with Hurler syndrome, a rare autosomal recessive disorder caused by a deficiency in the enzyme alpha-L-iduronidase. The patient exhibited typical symptoms, including developmental delays, ocular clouding, and distinctive skeletal deformities, along with mild cognitive abnormalities. Despite the presence of traditional clinical signs and elevated urine heparin and dermatan sulfate levels confirming the diagnosis, access to advanced treatments such as enzyme replacement therapy was severely limited due to socioeconomic constraints and a lack of diagnostic facilities in the region.
