Vitamin E Treatment for Long-Chain 3-Hydroxyacyl Coenzyme A (CoA) Dehydrogenase (LCHAD) Associated Neuropathy
Stopped early · Not applicable
Conditions studied: Peripheral Neuropathy, Mitochondrial Trifunctional Protein Deficiency
In brief
Purpose: People with a genetic defect in the ability to burn fat can also develop a problem with the nerves in their feet. The nerve problem, or neuropathy, can limit their ability to walk. Part of the treatment of their genetic defect in the ability to burn fat is to eat a very low fat diet. Vitamin E is found only in fatty foods like oils and nuts. People with a genetic defect in the ability to burn fat may have low vitamin E because of their low fat diet. The purpose of this study is to test whether vitamin E supplements can improve the nerve function in the feet of people with a genetic defect in the ability to burn fat. Procedures: Blood samples will be drawn at the beginning of the study, after 2 months and after 6 months of vitamin E supplements. The blood will be analyzed for plasma vitamin E concentrations. Around the time of each blood draw subjects will record all the food and beverages he or she consumes for three days. The subject will send the record to the investigator. Subjects will have a physical exam by a doctor specializing in nerves, a neurologist before and after taking vitamin E. They will have nerve function measured with a test called a nerve conduction velocity or NCV. Subjects will be given 800 international units (IU) of vitamin E per day for 6 months.
