Aim of the study was to investigate the levels of individual subpopulations of T-regulatory (T-reg) cells in patients with different phenotypes of chronic obstructive pulmonary disease (COPD) with moderate bronchial asthma and healthy volunteers. COPD was associated with increased level of natural (CD4+CD25high) T-cells, while emphysematous phenotype of disease was associated with the highest pool of natural CD4+CD25high. Bronchial asthma was associated with low levels of inducible (CD4+ FoxP3+ ) T-reg.

Objective. To study the physical growth and development of adolescents (aged 13–16 years) living in the Tomsk region. Material and Methods. This study is a framework (№299 from 18.07.2011) of the Department of Health Care of Tomsk region, we analyzed the results of medical examinations of adolescents (n = 7120, average age 13.98 ± 0.04, 49.87% – boys). Measurements of height and weight, the circumference of the chest and head (data rounded to 0.1 kg and 0.1 cm, respectively) are taken. The body mass index (BMI) is calculated as the ratio of weight (kg) / height2 (m2). Statistical analysis was performed using the software package Statistica for Windows 10.0 and the software StatCalc 6.0.Results. Average height of adolescents is (163.10 ± 0.09) cm. On Average boys are taller than girls ((165.34 ± 0.15) cm and (160.87 ± 0.11) cm, p < 0.001). The body weight is (53.99 ± 0.13) kg (boys – (55.28 ± 0.20) kg, girls – (52.72 ± 0.17) kg, p < 0.001). Boys chest circumference is (79.26 ± 0.30) cm, girls is (79.99 ± 0.13) cm, head circumference are (55.43 ± 0.07) cm and (54.77 ± 0.04) cm, respectively (p < 0.01). The results show difference between Tomsk boys and rest of the Russia Federation. The average BMI is (20.20 ± 0.04) kg/m2 (girls – (20.32 ± 0.07), boys – (20.08 ± 0.06) kg/m2). The urban lifestyle in Tomsk Region leads to boys obesity.Conclusion. The study revealed the regional physical growth and development characteristics. Anthropometric data in Tomsk region adolescents are higher than the same data in RF.

A statistical study of indicators of primary and chronic morbidity, mortality, clinical examinations, emergency care, the level of hospitalization of patients with asthma in the Tomsk Region for the years 1998—2008 was performed. This study used data of 843 thousand inhabitants of the Tomsk Region in the age of 18 years.During 1998—2008 in the Tomsk Region has made significant progress in the conduct of asthmatic patients, which is reflected in the cost of health care and higher quality care this patient.

To elucidate the molecular mechanisms of O. felineus impact into phenotypic variability of allergic diseases in the opisthorchis endemic region, we studied 104 patients with opisthorchosis, 92 patients with atopic bronchial asthma, 52 patients with a combination of both diseases, and 120 healthy persons. Standard clinical, immunological, and genetic methods were used. An association of opisthorchis invasion with the improvement of lung function signs and bronchial hyperreactivity was found. It was established, that IL-4-dependent mechanisms of atopy were suppressed by O. felineus antigens, in particular due to hyperproduction of IL-10 and transforming growth factor-beta. However, IL-5-dependant mechanisms were supported. A phenomenology of the cytokine gene differential expression was established, disclosing the molecular basis of the immune system function in diseases with polar immune response in the helminth endemic region.

The one step study was aimed at assessing of GINA knowledge in primary care doctors. The results demonstrated that the primary care doctors most often use GINA (2006) as source of information. But some systematic problems were revealed. Among them there is shortage of primary care doctors knowledge about modern asthma treatment approaches and low level of diagnostic equipment in primary care.
