BACKGROUND Niemann-Pick disease and β-thalassemia are distinct conditions with specific clinical and morphological manifestations. β-thalassemia is the most common inherited blood disorder in Iran whereas Niemann-Pick disease, a lysosomal storage disorder, is rarely found in this country. CASE PRESENTATION This 5-month old girl, a known case of β-thalassemia major was hospitalized for failure...

BACKGROUND Niemann-Pick disease type C is a rare inherited neurodegenerative disease involving impaired intracellular lipid trafficking and accumulation of glycolipids in various tissues, including the brain. Miglustat, a reversible inhibitor of glucosylceramide synthase, has been shown to be effective in the treatment of progressive neurological manifestations in pediatric and adult patients w...

UNLABELLED INTRODUCTION Niemann-Pick disease type C is a rare genetic lysosomal storage disease associated with impaired intracellular lipid trafficking and a range of progressive neurological manifestations. The influence of seizure activity on disease course and response to miglustat therapy is not currently clear. CASE PRESENTATION Niemann-Pick disease type C homozygous for NPC1 mutatio...

1. Niemann-Pick disease type C (NP-C) is an autosomal recessive lipidosis with protean clinical manifestations, distinguished biochemically by a unique error in cellular trafficking of exogenous cholesterol that is associated with lysosomal accumulation of unesterified cholesterol. A majority of patients with this phenotype are linked genetically to chromosome 18, the locus of Niemann-Pick dise...

Sea-blue histiocytosis is a rare disorder seen in patients with lipid metabolic or ceroid storage diseases. Sea-blue histiocytes are ceroid-laden macrophages detectable by May-Giemsa staining. We report a case of a 28-year-old woman diagnosed with Niemann-Pick disease at 2 or 3 years of age. To confirm this diagnosis, we examined her bone marrow, which revealed scattered foci containing aggrega...

Short-chain C6-sphingomyelin is an artificial substrate that was used in an acid sphingomyelinase activity assay for a pilot screening study of patients with Niemann-Pick disease types A and B. Using previously published multiplex and single assay conditions, normal acid sphingomyelinase activity levels (i.e. false negative results) were observed in two sisters with Niemann-Pick B who were comp...

Niemann-Pick is a lipid storage disease that results from a lysosomal enzyme deficiency (sphingomyelinase). It has different presentations, and it may affect various organs such as the central nervous system, kidney, liver, and spleen. Due to the complexity of the disease, careful perianesthetic management is necessary in order to reduce the risks and sequels. As there is little evidence availa...

background: the protein of niemann-pick type c1 (npc1) gene promotes the egress of cholesterol from late endosomes and lysosomes to other cellular compartments and contributes to a process known as reverse cholesterol transport. this study aimed to examine whether promoter methylation of npc1 is associated with risk of cardiovascular disease (cvd). methods: fifty cvd patients and 50 healthy sub...
