[The blood glutathione system in cerebral vascular diseases and its treatment with alpha-lipoic acid].
The changes of glutathione metabolism are rare in dyscirculatory encephalopathy and ischemic stroke (IS) of mild severity. The frequent and considerable changes have been revealed in IS of moderate and high severity as well as in hemorrhagic stroke. An increase of activities of glutathione peroxidase and glutathione transferase is the most typical. The increase of enzyme activity was not observed at the beginning of treatment after 3 days and in patients with severe degree of disease who died later. A standard therapy decreased the quantity and/or expression of changes of the glutathione metabolism in patients with IS of moderate and high severity while the addition of alpha-lipoic acid (alpha-LA) led to the complete normalization in IS of moderate severity and normalization of most parameters in IS of high severity. The increase of functional activity of the glutathione system at the early stage of treatment of IS and the favorable changes during the treatment, in particular after the addition of alpha-LA, were correlated with the improvement of neurological status assessed with the NIHSS. It has been confirmed that the glutathione system plays an important role in the tolerance to brain ischemia.
