Sitosterolemia Metabolism
SitosterolemiaEzetimibe has become the treatment choice for patients with sitosterolemia. Ezetimibe is an inhibitor of cholesterol absorption from the gastrointestinal tract. The purpose of this study is to determine if ezetimibe improves whole body plant sterol and cholesterol homeostasis.
Acute Nutritional Ketosis in VLCAD Deficiency
VLCAD DeficiencyFatty Acid Oxidation DefectsTo test if a ketone-ester based drink can boost muscle mitochondrial function in vivo in patients with VLCADD in order to establish a rational basis for therapeutic use in this disorder.
Biomarker for Homozygous Familial Hypercholesterolemia (BioHoFH)
Lipoprotein Lipase DeficiencyInborn Error of Lipid Metabolism1 moreDevelopment of a new MS-based biomarker for the early and sensitive diagnosis of Homozygous familial Hypercholesterolemia from blood
Natural History of Pearson Syndrome
Pearson SyndromeThe purpose of this 3-year, multi-site, non-randomized, prospective, observational study is to characterize the natural history of Pearson Syndrome. The Syndrome is a rare mitochondrial disorder due to a large-scale mtDNA deletion. Children typically present in their 1st two years of life (most in infancy) with anemia and/or pancreatitis. Most individuals with Pearson Syndrome die in childhood. Those who survive evolve to Kearns-Sayre Syndrome/Chronic Progressive External Ophthalmoplegia (KSS/CPEO) although accurate survival estimates are not yet known.
Genetic Study of Sitosterolemia
Lipid MetabolismInborn Errors1 moreOBJECTIVES: I. Identify the genetic defect and fine map the gene that causes sitosterolemia.

Relationship Between CETP Deficiency and Atherosclerosis in Patients With Hyperalphalipoproteinemia...
Low CETP ActivityCETP Deficiency3 moreThe aim of this study is to determine whether high high density lipoprotein-cholesterol(HDL-C) level and low Cholesteryl Ester Transfer Protein(CETP) activity is atherogenic or not in subjects who received health checkups. We investigate the association between CETP activities and the severity of atherosclerosis assessed by intima-media thickness (IMT) and compare the atherogenic change between in subjects with high HDL-C level, low HDL-C level, high CETP activities and low CETP activities by examining the morbidity rate of atherogenic diseases, the rate of ischemic electrocardiography(ECG) change, Calc Score of artery from chest X-ray, Ankle Brachial Index/Pulse Wave Velocity and various serum atherogenic markers. And we also examine the correlation between normal lipid profile and concentration, activity and function of surface lipoprotein in subjects with variety of lipoprotein levels, including patients with hyper-LDL-cholesterolemia, hyper-HDL-cholesterolemia with low or no CETP activity, patients with high level of remnant cholesterol or hyperlipoproteinemia of apolipoprotein(Apo)B-48.
Perioperative Research Into Memory, Genomics in the Intensive Therapy Unit: Alzheimer's
Cognitive ImpairmentApolipoprotein E4 moreThe current central dogma of long-term cognitive impairment after intensive care admission suggests an underlying neuroinflammatory dysregulation affecting neuronal function. This pathological process has not been fully elucidated and there has been little research into its genetic associations. Alzheimer's disease (AD) causes cognitive impairment through a process of abnormal beta amyloid deposition and neuronal death through localised activation of the innate immune system. It is the most prevalent disease affecting cognition. The Apolipoprotein E (APOE) gene is implicated in the progression of late-onset Alzheimer's disease and is a recognised neuroinflammatory modulator. It is possible that young individuals exposed to high levels of inflammation may experience an acceleration of this process. This study sets out to look for an association between APOE-∈4 possession and poor cognitive outcome after a major burn injury and intensive care admission.
