[Changes in the biochemical indices of patients with a recurrence of pulmonary tuberculosis].
ABSTRACT It was found that patients with pulmonary tuberculosis recurrences revealed an imbalance between the elevated level of lipid peroxidation and possibilities of antioxidant protection. The proteinase inhibitor system balance was disturbed. The general level of haptoglobulin rises while the number of persons with homozygote of haptoglobulin 2:2 rose and the number of persons with the heterozygote phenotype 2:1 reduced. Normalization of the biochemical indices in patients with recurrences was delayed.
