Substrate reduction therapy (SRT) with miglustat has been proposed for treatment of some lysosomal storage disorders. Based on the positive experience in Gaucher disease and experimental data in Tay-Sachs (TSD) and Sandhoff animal models, the authors investigated the clinical efficacy of SRT in two patients with infantile TSD. SRT could not arrest the(More)
The usefulness of bone turnover markers in Gaucher disease is still unclear and their utility in monitoring the effects of enzyme replacement therapy (ERT) on bone metabolism has not yet been investigated exhaustively. Skeletal involvement seems to improve slowly during ERT, but only a few studies evaluating bone mineral density (BMD) changes during a long(More)
OBJECTIVES Type II glycogenosis (GSDII) is a lysosomal storage disorder due to acid alpha-glucosidase (GAA) deficiency. Enzyme replacement therapy (ERT) with human recombinant alpha-glucosidase (rhGAA) has been demonstrated to be effective in the treatment of infantile forms of GSDII, but little information is available concerning late-onset phenotypes.(More)
Background. Enzyme Replacement Therapy (ERT) is the standard of care in Gaucher disease. The effects of withdrawal or reduced doses are debated, thus a retrospective cohort study was conducted to investigate clinical and laboratory differences in 34 Gaucher type 1 patients experiencing an ERT dosage reduction after the forced temporary imiglucerase shortage(More)
BACKGROUND Bone disease is a serious complication of Gaucher disease. Untreated, it can result in pain, permanent bone damage and disability. Enzyme replacement therapy reverses many of the clinical signs of Gaucher bone disease but early assessment and treatment, and regular monitoring, are essential in optimising outcomes. SCOPE In September 2005, a(More)
Glycogen storage disease type II (GSDII) is a recessively inherited disorder due to the deficiency of acid alpha-glucosidase (GAA) that results in impaired glycogen degradation and its accumulation in the lysosomes. We report here the complete molecular analysis of the GAA gene performed on 40 Italian patients with late onset GSDII. Twelve novel alleles(More)
For paediatric patients with Gaucher disease, enzyme replacement therapy (ERT) has the potential to prevent the development of serious, irreversible skeletal complications. Analysis of skeletal data for paediatric patients receiving ERT must take into account the pubertal growth spurt and developmental changes in bone marrow composition. In a study(More)
Three children with osteogenesis imperfecta, severe osteopenia, and repeated fractures were treated with cyclic infusions of aminohydroxypropylidene bisphosphonate (pamidronate) for a period ranging from 22 to 29 months. A clear clinical response was shown, with a striking reduction of new fracture episodes and a marked improvement in the quality of the(More)
The association between type 1 Gaucher disease and PD has been reported in the literature. The clinical picture is characterized by the predominance of bilateral akinetic-rigid signs and poor response to levodopa therapy. The authors describe four patients (two siblings) with type 1 Gaucher disease presenting with the following signs of typical PD:(More)
In Gaucher disease, enzyme replacement therapy usually reduces liver and spleen volumes and improves haematological abnormalities within 1 year. In contrast, skeletal manifestations of Gaucher disease are thought to respond more slowly. For example, decreased bone marrow glycolipid infiltration and increased bone mineral density have been reported to take(More)
