Critical assessment of chitotriosidase analysis in the rational laboratory diagnosis of children with Gaucher disease and Niemann-Pick disease type A…

2006

Laboratory diagnosis of lysosomal storage disorders, especially sphingomyelinase deficiency (Niemann–Pick disease type A/B) and Niemann–Pick disease type C (NPC) can be challenging. We therefore aimed to analyse the feasibility of first-step screening with specific chitotriosidase cut-off values in children ≤ 10 years of age with visceral organomegaly (hepatomegaly, splenomegaly, or hepatosplenomegaly) in whom a storage disorder was suspected. We conducted a retrospective, cross-sectional, referral, single-centre study to assess diagnostic test properties in 106 individuals. Median chitotriosidase activity was 12 655 nmol/h per ml (interquartile range 4693–20982) in Gaucher disease (GD); 78…

Association between polymorphisms of endothelial nitric oxide synthase gene (NOS3) and left posterior wall thickness (LPWT) of the heart in Fabry dis…

2008

Fabry disease is an X-chromosomal storage disorder due to loss-of-function mutations of the GLA gene encoding the lysosomal enzyme α-galactosidase A. Accumulating glycosphingolipid deposits disturb the function of various cells, in particular that of myocytes, arterial smooth-muscle cells, and vascular endothelium. Hypertrophic cardiomyopathy, for example measured by left posterior wall thickness (LPWT) of the heart, represents a major component of Fabry disease morbidity in adult patients. Endothelium-derived nitric oxide (eNO), produced by eNO synthase (eNOS), is a key regulator of vessel wall function and cardiovascular homeostasis. We analysed the effect of the polymorphisms c.894G > T …
