Antioxidant status in anorexia nervosa.
Int J Eat Disord. 1999 Jan; 25(1):99-103.IJ

Abstract

OBJECTIVE

The study of the antioxidant status in female adolescents (N = 82) with anorexia nervosa, by the measurement of erythrocyte tocopherol concentration, and the determination of activities of the main antioxidant enzymes: superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase.

METHOD

Tocopherol was measured by high-performance liquid chromatography (HPLC) with ultraviolet (UV) detection, and antioxidant enzyme activities by spectrometric methods using a Cobas Fara automated centrifugal analyzer.

RESULTS

Tocopherol was significantly decreased in the anorexic patients compared to reference values (p < .02). In 21% of patients, tocopherol levels were below the reference interval. Superoxide dismutase activity was significantly decreased (p < .0001), while catalase activity was increased (p < .0001). The activity of the glutathione system enzymes did not show significant differences between patients and controls.

DISCUSSION

The deficient concentration of erythrocyte tocopherol together with the altered antioxidant enzyme activities suggest a certain degree of oxidative damage in anorexia nervosa owing to both factors deficient micronutrient intake and oxidative stress.
