Tuberculosis among COPD Patients in Guba City, Azerbaijan

“…A related aspect of the above pathogenetic nosology is the development of destructive changes in the pulmonary parenchyma, caused, in particular, a metabolic disorder due to exposure to tobacco metalloproteinases or virulence factors Mycobacterium tuberculosis [2] [5] [8]. Among the diseases found at autopsy in patients who died of TB in Texas (USA) from 2000 to 2010, COPD was in 5th place [4] [9]. Paratuberculous process data in this study are not separately isolated.…”

At the same time, the experience of some authors shows that among all causes of hospitalization in infectious department of patients with this pathology tuberculosis occupies a significant place, second only to respiratory tract infections and pyothorax [1] [9] [7] [10]. There is a high probability of death of the patient within one year from the date of detection of tuberculosis-according to different authors varies between 18% -22% of all cases [6] [9]- [11].…”
