The authors discuss the contribution of the outstanding scientist, surgeon, health care organizer and academician Lev K. Bogush in development of original surgeries that saved ten thousands of patients with respiratory diseases. The main periods of phthisiatric surgery are described (no antibacterial drugs and limited technical possibilities of surgical treatment, defining the place of surgery after emergence of specific effective drug treatment, introduction of resection options, drug-resistant forms of disease in population).

The development of fibrosis is a determining factor in the pathogenesis, clinical course and prognosis of many diseases, among which interstitial lung diseases occupy a special place.

In this study, our objective was to identify a list of genes that correlate with high and low levels of gene expression in the lungs of pulmonary TB patients with different activity of chronic granulomatous inflammation. We compared gene expression in two groups of samples (with moderate and high activity of tuberculomas) to identify their characteristic gene signatures.

The purpose of the present study was to evaluate a real-time PCR system for 12 nontuberculous mycobacteria (NTM) species identification developed by Central Tuberculosis Research Institute (CTRI; Moscow, Russia) in cooperation with Syntol LLC (Moscow, Russia). NTM cultures (210 strains, 19 species), Mycobacterium tuberculosis complex (MTBC) cultures (21 strains, 2 species), non-mycobacterial microorganisms (18 strains, 13 species) were used for the first stage of the assay evaluation. Clinical samples (sputum, N = 973) positive for smear microscopy and MTBC/NTM DNA by a PCR-based screening assay collected from 819 patients were used for specificity and sensitivity evaluation.

View Article and Find Full Text PDFThe review is devoted to the urgent problem of modern pulmonology: the differential diagnosis of idiopathic pulmonary fibrosis (ILF). ILF occupies a special place among many interstitial lung diseases for a number of reasons: 1) it is a deadly disease; 2) early diagnosis and adequate antifibrotic therapy significantly extend the life expectancy of patients; 3) anti-inflammatory drugs (corticosteroids) and cytostatics with ILF that are widely used in other forms of interstitial lung diseases are ineffective and accelerate the progression of the process; 4) the commonality of the main clinical signs (increasing respiratory failure) of various interstitial lung diseases. The list of respiratory diseases with which ILF should be differentiated is huge, and if with diffuse lung lesions of a known nature (disseminated pulmonary tuberculosis, pneumoconiosis, etc.

Much is also known about the main stages of development and formation of specific adaptive immunity. However, from our point of view, not enough attention is being paid to the involvement of the immune system in the pathogenesis of clinically relevant TB abnormalities, as well as various forms of the disease.

Materials And Methods: A survey of 90 patients with a confirmed diagnosis of non - tuberculous mycobacteriosis of the lungs (NTML) was presented. The diagnosis of pulmonary mycobacteriosis was established in accordance with the criteria proposed in 2007 by the American Thoracic Society and the American Society of Infectious Diseases (ATS/IDRS).
Infectious process even at the initial stage after aerosol infection with Mycobacterium tuberculosis induced rapid changes in vaginal microbiota in mice. Rapid decrease in both the quantity and diversity of microbiota was noted, and then, partial recovery of normal flora was observed. Changes in vaginal microbiota was detected as soon as in 3-7 days after lung infection, while inflammatory changes appeared by day 35.

In this paper, we present the advantages of specific fluorescent antibody labelling, combined with laser scanning confocal microscopy (LSCM), for the detection of in histological specimens of lung tissues. We demonstrate that the application of LSCM allows: (i) The automatic acquisition of images of the whole slice and, hence, the determination of regions for subsequent analysis; (ii) the acquisition of images of thick (20-40 μm) slices at high resolution; (iii) single bacteria identification; and (iv) 3D reconstruction, in order to obtain additional information about the distribution, size, and morphology of solitary ; as well as their aggregates and colonies, in various regions of tuberculosis inflammation.

A skin test with a tuberculosis recombinant allergen (Diaskintest) is a new method for identification that has been implemented in Russia. This study was performed to compare the performances of Diaskintest and QuantiFERON-TB Gold (QFT) in adults and children with suspected TB in Moscow, Russia.
