RESUMO
Examination comprising the electrophysiologic method and study of the biochemical parameters of the antioxidant/lipid peroxidation system and metabolism of biologic amines in 163 patients with infiltrative pulmonary tuberculosis has revealed a clear interaction existing between the functional changes of the CNS state, the state of antioxidative defense (alpha-tocopherol) and serotonin. This allows an assumption that the antioxidant/lipid peroxidation system and serotoninergic system actively participate in the pathogenesis of development of neurotoxic reactions to antibacterial preparations in the clinical picture of tuberculosis.

Two groups of pulmonary tuberculosis patients were followed up to reveal the relation between the lipid peroxidation (LPO) processes and the function of the central nervous system (CNS) in pulmonary tuberculosis. Group 1 (n = 76) included subjects with normal baseline electroencephalographic findings; group 2 (n = 41) consisted of those with profound changes in the electroencephalogram. The findings of LPO processes were assessed by the blood levels of malonic dialdehyde and alpha-tocopherol. Group 2 showed a direct relationship between the progression of neurotic symptoms and the abnormal changes in the values of LPO processes. It is concluded that it is expedient to use antioxidants in the combined treatment of pulmonary tuberculosis patients to eliminate the baseline CNS changes caused by the specific process.
