[Lung microangiopathy in diabetics with lung tuberculosis].

Histological and electron-microscopic studies of intact lung specimens were carried out in 30 patients with pulmonary tuberculosis developing in the presence of type I (insulin-dependent) diabetes mellitus. Material for investigation was obtained by intrapulmonary biopsy carried out during diagnostic bronchoscopy. Signs of adenopathy were detected in lung areas distant from tuberculous in foci all the cases. The diabetic origin of this condition was confirmed by expressed correlation with changes in the retinal and renal vessels and absence of correlation with the duration of tuberculous process. The degree of pulmonary adenopathy has a negative impact on the course of tuberculosis and efficacy of its therapy.
