No differences in terms of oxidant and antioxidant status were found between the two groups. This was associated with no significantly different urinary VEGF and TGF\u2010\u03b2 levels. After 6 months, no significant differences in AER were observed between the two groups (<jats:italic>p<\/jats:italic> = 0.59). However, plasma and LDL\u2010vitamin E content were significantly higher in the vitamin E group compared to the placebo group (<jats:italic>p<\/jats:italic> = 0.0001 and <jats:italic>p<\/jats:italic> = 0.004, respectively). This was associated with a significantly longer lag phase (<jats:italic>p<\/jats:italic> = 0.002) and lower MDA (<jats:italic>p<\/jats:italic> = 0.049). However, no statistically significant differences were detected in terms of VEGF and TGF\u2010\u03b2 urinary levels.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>These data demonstrate that high\u2010dose vitamin E supplementation reduces markers of oxidative stress and improves antioxidant defence in young patients with T1DM. However, although it positively affects the oxidant\/antioxidant status, vitamin E supplementation does not reduce AER in patients with T1DM and persistent MA.
