Active clinical trials for "Hyperlipoproteinemia Type I"

This study plans to learn more about measuring Lipoprotein lipase (LPL) activity in humans. LPL is an enzyme in the breakdown of certain types of fats into smaller parts. Lipoprotein lipase deficiency (LPLD) is a very rare genetic disorder in which lipoprotein enzyme is no longer functional. This can cause conditions known as high triglycerides in the blood and inflammation of the pancreas. Investigational medications to treat LPLD are currently being developed. In order to see if these medications are effective, it is necessary to be able to accurately measure LPL activity in humans. LPL activity has been successfully measured in animal models after giving heparin. Heparin is a blood thinner which is approved by the FDA. It is originally used to prevent blood clots. This study will administer heparin to healthy adults through intravenous infusion (IV). Blood samples will be collected before and after the infusion to test LDL levels. The purpose of this study is to develop a cheap, more reliable standard for assessment of LPLD in patients

Development of a new MS-based biomarker for the early and sensitive diagnosis of Homozygous familial Hypercholesterolemia from blood

A retrospective, systematic study of reimbursed healthcare costs over a 10 year period in patients suffering from Familial Chylomicronaemia Syndromes (FCS) or Multifactorial Chylomicronaemia Syndromes (MCS) in order to establish the relative healthcare burden of both syndromes by linking the Hospices Civils de Lyon (HCL) registry of FCS or MCS patients and data obtained from FCS or MCS patients followed in Paris, Nantes and Lyon to the French National Health System (NHS) healthcare claims database, the Système National d'Information Inter-Régimes de l'Assurance Maladie (SNIIR-AM). A probabilistic approach will be used to link databases. This linkage will be based on the following variables: age, gender, date of discharge of any hospitalization, date of any imaging procedure. This study will help to describe, in real life, the management of severe hyperglyceridaemia in France. In addition, the descriptive results will help obtain a better understanding of the patients suffering from this disease, the burden of the disease and the healthcare consumption linked to this disease. Even if this consumption of care has been relatively unexplored until this point, it is not negligible. The potential of merging genomics and claims data for cardiovascular research could help to identify ways to optimize disease

FCS and MCS patients recruited from 7 academic reference centers were invited to answer a paper or a web questionnaire. Questions encompassed demographics, physical, cognitive and mental symptoms, health care circuit, past and current disease management, satisfaction regarding healthcare providers and impact on daily life.

Lipoprotein lipase deficiency (LPLD) is an autosomal recessive inherited condition caused by homozygosity or compound heterozygosity for mutations within the LPL gene. LPLD results in subjects presenting with fasting plasma triglyceride (TG) levels of > 10 mmol/l. LPLD typically presents in infancy or childhood with usual complaints of severe abdominal pain, repetitive colicky pains and repeated episodes of acute pancreatitis The most severe clinical complication associated with LPLD is acute pancreatitis. Pancreatitis in an LPLD subject often leads to prolonged hospital admissions (sometimes up to weeks). Subjects who survive repeated episodes of acute pancreatitis may develop chronic pancreatitis, ultimately resulting in endocrine and exocrine pancreatic insufficiency. The clinical manifestations of acute pancreatitis episodes related to LPLD are largely indistinguishable from acute pancreatitis due to other causes. However, collection of data relating to hospital admissions, laboratory test results, scan images and adverse events occurring concomitantly to the acute pancreatic episode should allow elimination of other causes of pancreatitis (e.g gallstones etc) and ultimately allow confirmation of LPLD-related acute pancreatitis. Characterization of the presentation of symptoms which occur around the time of known episodes of LPLD-related acute pancreatitis should also permit identification of episodes of acute pancreatitis which have previously been considered as unrelated or even unrecognized. The objective of the study is to re-assess and re-confirm data previously recorded about the incidence and severity of acute abdominal "pancreatitis" episodes in LPLD subjects previously enrolled on AMT clinical studies. To assess and document the presentation of acute abdominal episodes that occur around known episodes of pancreatitis and to permit the identification of possible new previously unrecorded episodes of pancreatitis based upon predefined diagnostic criteria. The objective is to recruit the 27 subjects previously enrolled in the above mentioned clinical studies.

The purpose of this program is to provide expanded access to volanesorsen for up to 100 Patients with Familial Chylomicronemia Syndrome (FCS).
