Bone-marrow transplantation has increased the survival of patients with mucopolysaccharidosis-I. We describe the spinal problems and their management in 12 patients with this disorder who have been followed up for a mean of 4.5 years since transplantation. High lumbar kyphosis was seen in ten patients which was associated with thoracic scoliosis in one. Isolated thoracic scoliosis was seen in a...

We analyzed placental tissue in one fetus with MPS II (iduronate sulphatase deficiency) and another with MPS VI (arylsulfatase B deficiency). Both were diagnosed prenatally, but families decided to continue pregnancies and placentas were collected at birth. We were able to demonstrate early storage of GAGs in both diseases by GAG measurement and microscopy analysis. Our results suggest that som...

Mucopolysaccharidosis I (MPS I) is a lysosomal storage disease due to deficiency in α-L-iduronidase (IDUA) that results in accumulation of glycosaminoglycans (GAGs) throughout the body, causing numerous clinical defects. Intravenous administration of a γ-retroviral vector (γ-RV) with an intact long terminal repeat (LTR) reduced the clinical manifestations of MPS I, but could cause insertional m...

Bone marrow transplantation (BMT) is a therapeutic option for patients with genetic storage diseases. Between 1979 and 2002, eight patients, four females and four males (1 to 13 years old) were submitted to this procedure in our center. Six patients had mucopolysaccharidosis (MPS I in 3; MPS III in one and MPS VI in 2), one had adrenoleukodystrophy (ALD) and one had Gaucher disease. Five patien...

A neonate presented with mucopolysaccharidosis-like phenotypic expression and typical signs of dysostosis multiplex but without urinary excretion of glycosaminoglycans. Investigations of lysosomal enzymes in cultured fibroblasts revealed a mucolipidosis type 2, known as I-cell disease. We describe the fatal course of the patient due to complications of an uncommon dilated cardiomyopathy in this...

1314 deformity with mesomelic dwarfism of both upper and lower limbs. It is. the commonest variety of mesomelic dwarfism(3). Madelung deformity may also be seen associated with diverse disorders such as mucopolysaccharidosis, Turner's syndrome, achondroplasia, dyschondroplasia (Ollier's disease), multiple exostosis and multiple epiphyseal dysplasia. Madelung's original description of the lesion...

Morquio syndrome or MPS IVA is a rare type of lysosomal storage disease associated with highly specific dental abnormalities. We present two siblings with enamel hypoplasia and skeletal abnormalities. A diagnosis of mucopolysaccharidosis type IVA was reached based on the clinical, radiographic, and dental findings of the patients. The dental findings are useful diagnostic aid for the early diag...

A 6 month-old infant presenting with severe mitral regurgitation was found to have hepatosplenomegaly, corneal clouding, and Alder-Reilly granules in the leucocytes. Extremely low levels of beta glucuronidase confirmed the diagnosis of Sly disease (Mucopolysaccharidosis VII). This is the first case of MPS VII reported from India.

After a herculean data-gathering effort, in this issue of Blood, Aldenhoven and colleagues from Europe and North America provide an eye-opening assessment of long-term neurocognitive, organ, joint, and tissue function after allogeneic transplantation of children with mucopolysaccharidosis type I–Hurler syndrome (MPS-IH), along with an analysis defining a path to better these outcomes.
