BACKGROUND Pompe disease is a hereditary metabolic myopathy, for which enzyme replacement therapy (ERT) has been available since 2006. We investigated whether ERT reduces fatigue in adult patients with Pompe disease. METHODS In this prospective international observational survey, we used the Fatigue Severity Scale (FSS) to measure fatigue. Repeated measures ANOVA was used to analyze the data ...

patients identified by the neonatal screening and treated earlier than historical patients showed improved outcome in terms of motor activity and ventilatory-free survival. The immune status of PD patients has emerged as another important factor that impacts ERT efficacy. In a recent study the effects of ERT in 11 cross-reactive immunological material (CRIM) negative patients were compared with...

BACKGROUND The cost-effectiveness of enzyme replacement therapy (ERT) compared to standard medical care was evaluated in the Dutch cohort of patients with Fabry disease. METHODS Cost-effectiveness analysis was performed using a life-time state-transition model. Transition probabilities, effectiveness data and costs were derived from retrospective data and prospective follow-up of the Dutch st...

Pompe disease is a lysosomal storage disease characterized by massive glycogen deposition in skeletal, cardiac and smooth muscle secondary to the deficiency of acid α-glucosidase (GAA) [1]. Once rapidly fatal, it has become a treatable condition since the development of enzyme replacement therapy (ERT) with alglucosidase α (recombinant human GAA [rhGAA], Myozyme/Lumizyme Genzyme Corp. Cambridge...

T he advent of effective enzyme replacement therapy (ERT) has kindled considerable interest in Fabry disease; ERT offers the promise of altering the natural history of this unusual form of proteinuric chronic kidney disease (CKD). Fabry disease is a rare, X-linked, lysosomal storage disorder caused by deficient activity of the lysosomal enzyme -galactosidase A, with accumulation of its substrat...

We aimed to establish the profile of Irish patients with Hunter Syndrome (Mucopolysaccharidosis type II, MPS II) receiving weekly intravenous Enzyme Replacement Therapy (ERT) with recombinant iduronate-2-sulfatase and to assess the social impact and parental opinion of ERT through the use of a parental questionnaire. Nine patients aged 3.5- 14 years have received a mean of 2 (range 0.5-3.5) yea...

Recombinant mouse beta-glucuronidase administered intravenously to newborn mice with mucopolysaccharidosis type VII (MPS VII) is rapidly cleared from the circulation and localized in many tissues. Here we determine the tissue distribution of injected enzyme and describe its effects on the histopathology in 6-wk-old MPS VII mice that received either one injection of 28,000 U recombinant beta-glu...

Objective. To determine the effects of enzyme replacement therapy (ERT) on the hearing acuity in patients with Fabry disease. Materials. The study sample comprised 34 ears of 17 affected patients who underwent pure-tone audiometry before and after ERT. Methods. The patients were studied in relation to factors such as changes in hearing, presence of accompanying symptoms, status of renal and car...

There are several inherited disorders that involve abnormal storage of lipids in tissues leading to severe compromise of organs. Sadly, these are often accompanied by lifelong morbidity and early mortality. Disorders such as Gaucher, Fabry, and lysosomal acid lipase deficiencies (Wolman and cholesteryl ester storage diseases) have been known for many years, and provide a difficult and frustrati...
