Intravenous enzyme replacement therapy (Alglucerase; Ceredase; Genzyme Corp, Boston, MA) is an effective and safe treatment for patients with type 1 Gaucher disease. In an attempt to reduce its high cost, a "low-dose high-frequency" protocol (30 U/kg/mo, 3 times a week) was introduced and found to be as effective as the original high-dose protocol (60 U/kg every 2 weeks). Because receiving freq...

Gaucher disease is the most common lysosomal storage disease. It is caused by the defective activity of acid β-glucosidase, which results in the accumulation of lipid glucocerebroside in macrophages throughout the body. In this case report we describe the case of a young adult woman with splenomegaly as the primary manifestation of this pathology. This is a case of type 1 Gaucher disease becaus...

Type 1 Gaucher disease families were studied in an attempt to establish a phenotype/genotype correlation in affected persons and also to identify carriers accurately. In the Portuguese type 1 Gaucher patients, screening for mutations N370S, L444P, R463C, and 1066 + 1 G-->A allowed the identification of 85% of the alleles among unrelated patients. A subclinical case with genotype N370S/1066 + 1 ...

Gaucher disease is a relentless progressive multi-systemic disorder caused by deficiency or inadequate function of lysosomal β-glucocerebrosidase. The resultant accumulation of the substrate glucocerebroside causes the organ damage. The classic clinical picture of organomegaly, cytopenia and bone pain or disease should always alert the practitioner and place Gaucher disease into the differentia...

Gaucher disease is a common lysosomal storage disease caused by a defect of acid beta-glucosidase (GCase). The optimal in vitro hydrolase activity of GCase requires saposin C, an activator protein that derives from a precursor, prosaposin. To develop additional models of Gaucher disease and to test in vivo effects of saposin deficiencies, mice expressing low levels (4--45% of wild type) of pros...

Gaucher disease is caused by the defective activity of the lysosomal hydrolase, glucosylceramidase. Although the x-ray structure of wild type glucosylceramidase has been resolved, little is known about the structural features of any of the >200 mutations. Various treatments for Gaucher disease are available, including enzyme replacement and chaperone therapies. The latter involves binding of co...

INTRODUCTION Gaucher disease is caused by a deficiency of the enzyme β-glucocerebrosidase. Treatment with enzyme replacement therapy has been available for the past two decades but, although effective, enzyme replacement therapy can be delivered only by intravenous infusion every other week. The oral substrate reduction therapy miglustat (Zavesca®) has been available in Europe since 2002 for th...

Data from the International Collaborative Gaucher Group Gaucher Registry were analysed to assess the relationship between enzyme replacement therapy with imiglucerase (ERT) and incidence of avascular necrosis (AVN) in type 1 Gaucher disease (GD1), and to determine whether the time interval between diagnosis and initiation of ERT influences the incidence rate of AVN. All patients with GD1 enroll...

BACKGROUND Gaucher disease, the most common sphingolipid storage disease, results in accumulation of glucocerebroside in macrophages or "Gaucher cells". In a preliminary screening of 109 patients with type I disease, when asked specifically about dry mouth, approximately one quarter claimed to suffer from this symptom. AIM To ascertain whether decreased salivary output is a feature of Gaucher...

Gaucher disease is an autosomal recessive glycolipid storage disease characterized by a deficiency of glucocerebrosidase. The disease is most common in persons of Ashkenazi Jewish ancestry and the most common mutation, accounting for about 75% of the mutant alleles in this population, is known to be an A----G substitution at cDNA nucleotide (nt) 1226. Screening for this disease has not been pos...
