Apolipoprotein Deficiency Research Study

Apolipoprotein Deficiency Research Study - Diagnosis and Followup Protocol

If you have a mutation in a plasma apolipoprotein (the protein portion of a lipoprotein), you are invited to participate in a study that will evaluate the development and follow the natural history of atherosclerosis in your disorder. Many apolipoprotein mutations have been described including apolipoprotein A-I (apoA-I), apolipoprotein A-II (apoA-II), apolipoprotein B (apoB), apolipoprotein C-I (apoC-I), apolipoprotein C-II (apoC-II), apolipoprotein C-III (apoC-III) and apolipoprotein E (apoE). A variety of clinical and research techniques will be used to assess and follow the development of atherosclerosis. Recommendations for treatments will be provided based upon these findings.

Eligible persons will undergo a comprehensive evaluation. All patients will remain under the care of their own physician who will receive results of the laboratory and diagnostic tests. In most cases, you will be invited back for yearly evaluations related to other studies. There is no cost to you for travel or medical testing.

If you have homozygous sitosterolemia, you are invited to participate in a study that will evaluate a new investigation drug that inhibits cholesterol absorption. Ezetimibe (SCH-58235) reduces plant sterol concentrations in patients with sitosterolemia with short term treatment. Ezetimibe was well tolerated in these patients. The long term safety and benefit is being evaluated in this one year study.

Sitosterolemia should be suspected in children with hypercholesterolemia, tuberous and tendinous xanthomas, recurrent arthritis and an unusually good improvement in cholesterol levels due to diet and a bile acid resin binder.
