Zusammenfassung
Introduction: PCT is a disorder of heme biosynthesis resulting from a decreased activity of uroporphyrinogen decarboxylase enzyme. Heme precursors, predominantly uroporphyrin accumulate in the blood, liver, urine, stool, and skin. Iron toxicity is associated with pathological free radical reactions. Alpha-lipoic acid is a coenzyme of pyruvate and alpha-ketoglutarate dehydrogenase. Alpha-lipoic acid showed protective effects against lipid peroxidation, protein carbonyl formation, NO and ONOO-. Aim: We investigated the effect of alpha-lipoic acid on porphyrin concentration and iron metabolism in PCT patients with…
