Direct enzyme replacement therapy (ERT) has been introduced as a means to treat a number of rare, complex genetic conditions associated with lysosomal dysfunction. Gaucher disease was the first for which this therapy was applied and remains the prototypical example. Although ERT using recombinant lysosomal enzymes has been shown to be effective in altering the clinical course of Gaucher disease...

INTRODUCTION: Mucopolysaccharidosis VI (MPS VI, Maroteaux-Lamy syndrome) an autosomal recessive lysosomal storage disorder accumulation of incomplete dermatan sulfate (DS) glycosaminoglycans (GAGs), originated from the deficiency of galactosamine sulfatase (arylsufatase B) [1]. DS is important for the production of small leucine-rich repeat proteoglycans (e.g. decorin and biglycan which are use...

Mucopolysaccharidosis VI (MPS VI; Maroteaux-Lamy syndrome) is an autosomal recessive lysosomal disorder caused by deficiency of N-acetylgalactosamine-4-sulfatase (ARSB), which is required for the degradation of dermatan sulfate. We recently reported mutational screening of 12 Spanish and 4 Argentinian MPS VI patients. In the present study, seven missense mutations (c.245T>G [p.L82R], c.413A>G [...

In October 2008, more than 80 clinicians and scientists gathered at the Children’s Hospital Oakland Research Institute in Oakland, California, at a two day meeting of experts entitled “Promoting Bone Health in MPS VI: Framing New Therapies”. The meeting was jointly sponsored by Children’s Hospital and Research Center Oakland and the Department of Pediatrics, University of Padova, Italy. The mee...

OBJECTIVE To describe the profile of joint mobility and grip and pinch strength of MPS VI patients and to correlate this with urinary excretion of glycosaminoglycans (GAGs), ARSB activity, and the distance covered in a 6-minute walking test (6MWT). METHODS This was an observational study of 28 patients with MPS VI, who had not undergone specific treatment. All patients were assessed for ampli...

INTRODUCTION Maroteaux-Lamy syndrome, or mucopolysaccharidosis (MPS) type VI, is an autosomal recessive lysosomal storage disease caused by a deficient activity of the enzyme arylsulfatase B (ARSB), required to degrade dermatan sulfate. The onset and progression of the disease vary, producing a spectrum of clinical presentation. So far, 133 mutations have been reported. The aim of this study is...

10.1586/14750708.3.1.9 © 200 Since enzyme-replacement therapy has been successfully introduced for patients with Gaucher disease, Fabry disease and mucopolysaccharidosis Type I, the principle of this treatment has also been taken into consideration for individuals who are affected by mucopolysaccharidosis Type VI (Maroteaux–Lamy disease), a rare lysosomal storage disorder with multiple organ an...

We report studies that suggest enzyme replacement therapy will result in a significant reduction in disease progression and tissue pathology in patients with Maroteaux-Lamy syndrome (Mucopolysaccharidosis type VI, MPS VI). A feline model for MPS VI was used to evaluate tissue distribution and clinical efficacy of three forms of recombinant human N-acetylgalactosamine-4-sulfatase (rh4S, EC 3.1.6...
