Endothelial Function in a Sample Group of Patients From the ICARE Study

Fifty patients will be randomly sampled from the ICARE untreated cohort (registry) of diabetic patients with Hp2-2 phenotype which were not randomised to treatment under ICARE study. Patients will be randomised to either vitamin E 400 IU/d or Placebo upon sampling for EFI study.

The patients will be tested for endothelial function by a method of Post Ischemic Flow mediated Dilatation.

all patients will undergo a baseline Endothelial Function test and then start taking the study drug for 2 months. at the end of two months of therapy the patients will undergo a second endothelial function test, then therapy will be stopped for 2 weeks and a cross over will be performed for an additional 2 months of therapy which in the end the third and final endothelial function test will be done.

An interim Results analysis is set to be done once the first 20 patients completed the protocol. In case of significant differences between the groups, study principal investigators will decide about study completion.
