10.2217/14750708.4.3.231 © 2 Hunter syndrome (mucopolysaccharidosis II) is a rare, X-linked disorder caused by the missing or deficient lysosomal enzyme, iduronate-2-sulfatase, which leads to tissue and organ accumulation of glycosaminoglycans, resulting in multisystem dysfunction with death occurring most commonly in the first or second decade of life. Enzyme-replacement therapy with idursulfa...

A 53-year-old asymptomatic man with no family history of Fabry disease or hypertrophic cardiomyopathy (HCM) exhibited increased ECG voltages (Figure [A]) and primary cardiac hypertrophy (left ventricular maximal wall thickness 16 mm and myocardial mass 163.2 g) with preserved contractility at cardiac magnetic resonance (Figure [D]). He was diagnosed in 2006 to be affected by Fabry disease cardi...

Pancreatic enzyme replacement therapy is currently the mainstay of treatment for nutrient malabsorption secondary to pancreatic insufficiency. This treatment is safe and has few side effects. Data demonstrate efficacy in reducing steatorrhea and fat malabsorption. Effective therapy has been limited by the ability to replicate the physiologic process of enzyme delivery to the appropriate site, i...

In a patient with hyperargininemia, enzyme replacement therapy such as whole blood exchange transfusion or erythrocyte transfusion was performed, and its effect was confirmed in vitro as well as in vivo. The patient has been treated with the restriction of protein intake, oral administration of an essential amino acid mixture, and sodium benzoate or phenylacetic acid. With these treatments, his...

Glucocerebrosidase and ceramidetrihexoside-alpha-galactosidase were obtained in a high degree of purity from human placental tissue. The enzymes were infused in Gaucher and Fabry patients, respectively. Following the administration of the proteins to supplement the genetically determined deficiencies, there resulted a specific reduction in the accumulated hlycolipids in the circulation and live...

Fabry disease is an X-linked lysosomal storage disorder that results from a deficiency of the enzyme a-galactosidase A (a-Gal A). The lack of a-Gal A leads to incomplete metabolism and progressive lysosomal accumulation of glycosphingolipids, particularly globotriaosylceramide (GL3). This process causes damage to endothelial, perithelial and smooth-muscle cells of the vascular system, glomerula...

OBJECTIVE The lysosomal storage disease alpha-mannosidosis is caused by the deficiency of the lysosomal acid hydrolase alpha-mannosidase (LAMAN) leading to lysosomal accumulation of neutral mannose-linked oligosaccharides throughout the body, including the brain. Clinical findings in alpha-mannosidosis include skeletal malformations, intellectual disabilities and hearing impairment. To date, no...

We report the effects of enzyme replacement therapy in a patient with Gaucher's disease associated with a monoclonal gammopathy. Alglucerase induces a linear decline in immunoglobulin and beta 2-microglobulin levels. This observation suggests that this treatment decreases the chronic antigenic stimulation commonly found in Gaucher's disease.
