[The values of the lipid peroxidation-antioxidative defense system as predictors of the poor course of infiltrative pulmonary tuberculosis].

The authors have studied whether an indirect clinical-and-laboratory assessment of the extent of a destructive process in the tuberculous infiltrates and that of concomitant pleural affection can be made from the values of the lipid peroxidation-antioxidative defense (PLO-AOD) system in the blood of patients with infiltrative pulmonary tuberculosis (IPT). Regression analysis has indicated that PLO-AOD values significantly reflect the extent of X-ray verified destructions in the tuberculous infiltrates, concomitant pleural involvements, the specific features of immunity of patients with IPT. The neural network technology used to analyze the baseline PLO-AOD values has been ascertained to permit a reliable prognosis of decay cavity closure 4 months after the initiation of medical treatment and of a need for surgical treatment for IPT.
