Pulmonary Fibrosis and Progressive Pulmonary Fibrosis in a Prospective Registry of Interstitial Lung Diseases in Eastern Siberia.

Interstitial lung diseases (ILD) are part of a large heterogeneous group of diseases that differ in many ways (in their cause, clinical presentation, and response to therapy, etc.), but there are similar pathophysiological mechanisms involved in the development of the inflammation and/or fibrosis of the lungs. Currently, several criteria for pulmonary fibrosis (PF) and progressive pulmonary fibrosis (PPF) are proposed, and the information on the prevalence and characteristics of these conditions is limited.

[Bronchial hyper-reactivity and chronic obstructive pulmonary disease].

Bronchial hyper-reactivity (BHR) is a highly sensitive indicator of bronchial asthma, a main predictor of obligatory property of this disease. Modern studies show that BHR occurs in 55-87% of the patients with chronic obstructive pulmonary disease (COPD). Recent epidemiological studies demonstrated that BHR is an independent predictor of COPD risk and the second most important risk factor of COPD after smoking.

[Antimicrobial properties of antiseptic composite with prolonged action].

Antimicrobial properties of a composite based on decamethoxine and modified polysaccharides (carboxymethylamylum, oxyethyl-cellulose) were studied. The composite was shown to have high antimicrobial activity against grampositive and gramnegative bacteria under different conditions of the experiment.

Differential expression of the β2-adrenoreceptor and M3-cholinoreceptor genes in bronchial mucosa of patients with asthma and chronic obstructive pulmonary disease.

Background: Bronchodilators are drugs of choice in the combined therapy of bronchial asthma and chronic obstructive pulmonary disease (COPD). However, the therapeutic sensitivity is variable between patients, probably because of structural features of regulating molecules or variation in key genes' expression.

Objectives: The aim of this study was to evaluate the β2-adrenoceptor (ADRB2) and M3-cholinoreceptor (CHRM3) gene expression in bronchial mucosa in patients with COPD and different severity of asthma.

[Heart valve calcification in patients with chronic kidney disease].

The aim of the study was to identify factors related to heart valve calcification (HVC) and effect of HVC on intracardiac hemodynamics in patients with chronic kidney disease (CKD). 377 CKD patients of the control group and 132 ones treated by hemodialysis (HD) were examined using echocardiography, cardiomonitoring, measurement of the carotid intima-media thickness and mineral bone density, X-ray imaging of calcified abdominal aorta. HVC was diagnosed in 38.
