Abstract

Mitochondrial diseases are due to impairment of the mitochondrial respiratory chain. A plausible pathogenic mechanism leading to cellular dysfunction and phenotypic expression is oxidative stress, but there are surprisingly few clinical studies on this subject. Glutathione (GSH) deficiency has been reported in mitochondrial diseases, and the biosynthesis of glutathione depends on cysteine availability. We have examined oxidative stress biomarkers [advanced oxidation protein products (AOPP) and ferric reducing antioxidant power (FRAP)] in blood samples from 27 patients and 42 controls. AOPP levels were greater in patients than in controls (P value
