Coenzyme Q, Vitamin E and Apo-E alleles in Alzheimer Disease.

Neurodegenerative Diseases represent the most common cause of Dementia, about 5-10% of the population aged above 65 years and about 30% above 80 years. A study about Apo-E alleles, Coenzyme Q and Vitamins E as biological indicators was performed in plasma samples of patients aged from 30 to 85 years, affected by Neurodegenerative Diseases. The results were compared with control subjects of approximately the same ages as the reference group. A frequency of 21.7% of epsilon4 allele in control group was estimated, against 15.8% observed in patients. The frequency of epsilon2 and epsilon3 alleles was 13.0% and 65.2% in the control group against 10.5% and 73.7% in patients. No significant differences were observed between the frequency of epsilon3/epsilon3 genotype and epsilon3/epsilon4 genotype in the control group compared to patients' group. The frequencies observed in epsilon2/epsilon3 genotype groups were 8.7% vs 15.8% and of e2/e4 genotype 17.4% vs 5.3%. The epsilon2/epsilon2 and epsilon4/epsilon4 genotypes were not identified in any groups. Plasma CoQ10 concentrations were similar in patient and control groups and no differences were found even taking into account the distribution of male and female subjects in the two groups. Also, vitamin E did not provide evidence of any differences between groups and the analysis among sexes revealed that again vitamin E concentrations were similar in between subgroups.[1]
