ClinConnect Summary

We propose to investigate human in vivo lipoprotein metabolism using radiolabeled apolipoproteins on plasma lipoproteins. Paired kinetic studies using dual-labeled iodinated lipoproteins and apolipoproteins are performed in healthy volunteer controls with normal lipids and subjects with dyslipidemia under controlled metabolic conditions. Studies are designed to formulate metabolic pathways in patients with undefined genetic disorders of lipid metabolism as well as in healthy volunteers to provide original insights into normal and pathologic metabolic pathways. All kinetic data is computer a...

Eligibility criteria

• * INCLUSION CRITERIA:
• • Subjects with new and undefined dyslipidemia-particularly familial disorders with extreme phenotypes.
• • Healthy normal volunteers - (18 years old or older) controls to investigate the formation of HDL for prebeta HDL.
• • Euthyroid.
• EXCLUSION CRITERIA:
• • Healthy control volunteers are initially screened for secondary causes of hyperlipidemia and are excluded if they have any clinically significant laboratory abnormality (i.e., liver disease, disease, kidney disease, endocrine disease,), chronic medical problems (i.e., hypertension, migraines, inflammatory bowel, hepatitis, HIV) or require any chronic medications (i.e., acne, asthma).
• • The healthy control volunteers weight must fall within the current guidelines for ideal body weight.
• • Pregnant women.
• • Unwilling to follow metabolic diet.
• • Allergic to iodine.
• • Unable to sign consent form.
