Tissue hypoperfusion leads to cellular oxidative and peroxidative damage due to biochemical disorders in the oxygen and substrate metabolism. The metabolic turnover of glutathione (GSH) represents one the main cytoprotective systems against the peroxide attack and the depletion or defect in resynthesis of this compound is accompanied by pathological consequences. In the present study the clinical effects of glutathione depletion were investigated in conditions of acute tissue hypoxia due to marked haemolysis in glucose-6-phosphate dehydrogenase deficient patients (favism syndrome). In these subjects a significant marker of the tissue oxidative damage was represented by the uric acid blood levels, presumably linked to xanthine-hypoxanthine altered metabolism. To antagonize the effects of oxyradical pathology, reduced glutathione was administered to a group of patients and the results confirmed the cytoprotective role played by the GSH supplementation. The GSH action was evident on the tissue metabolism and this supports the opinion that reduced glutathione could represent a new and interesting therapeutic approach in marked and acute hypoxic conditions.
