RESUMO
AIM: To identify predictors for the poor outcome of infiltrative pulmonary tuberculosis (IPTB). SUBJECTS AND METHODS: The social, epidemiological, and medical risk factors and clinical features of IPTB were assessed in 130 first detected patients. The findings were classified using a cluster analysis and then a variance analysis, followed by the ranking of its results. RESULTS: The primarily diagnosed disseminated destructive process with respiratory and cardiopulmonary failure, excretion of both resistant and multi-resistant pathogenic bacteria had a strong impact on the poor outcome of tuberculosis (TB) in the first detected patients. Its outcome was also influenced by a set of social factors, such as poor material living conditions, stay in corrective labor facilities, and a lack of education. The unfavorable outcome of TB was significantly due to organizational factors, such as bad habits; refusal to undergo fluorography during a few years; and a medical factor as comorbidities. CONCLUSION: Based on the identified factors, the authors formulated recommendations for working with the first detected IPTB patients at risk for a poor disease outcome.
