Lipid peroxidation, vitamins C, E and reduced glutathione levels in patients with pulmonary tuberculosis.

The present study examined the relationship between lipid peroxidation and vitamin C, vitamin E and reduced glutathione levels in plasma, erythrocytes and erythrocyte membranes of pulmonary tuberculosis patients and an equal number of age-and sex-matched healthy subjects. Enhanced plasma, erythrocytes and erythrocyte membrane lipid peroxidation with concomitant decline in vitamin C, vitamin E and reduced glutathione levels were found in pulmonary tuberculosis patients. The elevated lipid peroxidation and decreased vitamin C, vitamin E and reduced glutathione levels indicate the potential of oxidative damage to erythrocytes and erythrocyte membranes of pulmonary tuberculosis patients.
