Potential efficacy of enzyme replacement and substrate reduction therapy in three siblings with Gaucher disease type III.

We report three siblings with Gaucher disease type III, born between 1992 and 2004. During this period, new developments resulted in different potential therapies, changing clinical practice. The two eldest siblings received enzyme replacement therapy (ERT) from the age of 24 and 5 months respectively, later followed by an increase in dosage.

Home treatment with enzyme replacement therapy for mucopolysaccharidosis type I is feasible and safe.

Objective: Intravenous enzyme replacement therapy (ERT) with recombinant alpha-L-iduronidase may ameliorate the non-neurological symptoms in patients with mucopolysaccharidosis type I (MPS I). Since home-based ERT for Gaucher and Fabry diseases has been reported to be safe and successful, we investigated the feasibility and safety of home therapy in patients with MPS I.

Setting: This two-centre study included 17 ERT-treated MPS I patients between 1 and 35 years of age.

Development of adamantan-1-yl-methoxy-functionalized 1-deoxynojirimycin derivatives as selective inhibitors of glucosylceramide metabolism in man.

In this article, we present a straightforward synthesis of adamantan-1-yl-methoxy-functionalized 1-deoxynojirimycin derivatives. The used synthetic routes are flexible and can be used to create a wide variety of lipophilic mono- and difunctionalized 1-deoxynojirimycin derivatives. The compounds reported here are lipophilic iminosugar based on lead compound 4, a potent inhibitor of the three enzymes involved in the metabolism of the glycosphingolipid glucosylceramide.

Quantitative analysis of the targeting of mannose-terminal glucocerebrosidase. Predominant uptake by liver endothelial cells.

Gaucher's disease is an inherited lysosomal storage disorder that is caused by a deficiency of glucocerebrosidase. The resulting accumulation of the substrate glucosylceramide in macrophages of liver, spleen, and bone marrow causes severe clinical symptoms. Gaucher's disease is treated by intravenous administration of a modified glucocerebrosidase (Alglucerase), which has exposed mannose residues to promote uptake by target macrophages.
