The character of changes of inflammatory-cellular pattern of bronchial secretion in patients with asthma in association with cold airway hyperresponsiveness (CAHR) under the influence of standard therapy has been studied little. The aim of the present work is to study dynamics of cellular profile, neutrophilic component of bronchial inflammation under the combination therapy of asthmatics with CAHR. 12 asthma patients with CAHR were studied upon the number of cells of the induced sputum (IS), peroxidase, cytolytic and destructive activity of eosinophils and neutrophils in the sputum, lung function and asthma control with the help of questionnaire Asthma Control Test (АСТ) before and after the therapy with the combination of budesonide/formoterol. Before the therapy the patients had a low level of asthma control (14.4±1.2 points of ACT), FEV1 was 87.4±3.3% from predicted values; in IS neutrophils prevailed (26.4±1.7%) over eosinophils (18.5±2.6%); the level of myeloperoxidase (mean cytochemical coefficient) was 65.9±5.4 pixels. After 48 weeks of the observation only in 58% of patients the criteria of good control of asthma and the improvement of lung function were achieved. In IS there was a decrease of eosinophils (11.4±3.2%; p=0.045); the intensiveness of eosinophils and neutrophils cytolysis dropped; intracellular concentration of myeloperoxidase grew (98.2±14.1 pixels; p=0.0637); destructive changes in granulocytes were registered but the number of neutrophils remained high (34.0±8.2%, р=0.34), which was considered as the factor of stable initiation of inflammation and oxidative stress. Thus, the use of anti-inflammatory treatment regime lasting 48 weeks with combination of budesonide/formoterol oriented to achieve clinical criteria of asthma control in patients with CAHR does not allow to achieve correction of the level of neutrophilic inflammatory component. Quantitative index of neutrophils in IS in these patients has prognostic value for the possible loss of achieved asthma control.

We investigated whether obesity is associated with airway hyperresponsiveness in otherwise healthy humans and, if so, whether this correlates with a restrictive lung function pattern or a decreased number of sighs at rest and/or during walking. Lung function was studied before and after inhaling methacholine (MCh) in 41 healthy subjects with body mass index ranging from 20 to 56. Breathing pattern was assessed during a 60-min rest period and a 30-min walk. The dose of MCh that produced a 50% decrease in the maximum expiratory flow measured in a body plethysmograph (PD50MCh) was inversely correlated with body mass index ( r2 = 0.32, P < 0.001) and waist circumference ( r2 = 0.25, P < 0.001). Significant correlations with body mass index were also found with the maximum changes in respiratory resistance ( r2 = 0.19, P < 0.001) and reactance ( r2 = 0.40, P < 0.001) measured at 5 Hz. PD50MCh was also positively correlated with functional residual capacity ( r2 = 0.56, P < 0.001) and total lung capacity ( r2 = 0.59, P < 0.001) in men, but not in women. Neither PD50MCh nor body mass index correlated with number of sighs, average tidal volume, ventilation, or breathing frequency. In this study, airway hyperresponsiveness was significantly associated with obesity in otherwise healthy subjects. In obese men, but not in women, airway hyperresponsiveness was associated with the decreases in lung volumes.

International guidelines indicate that the main criterion of asthma management is asthma control level. The aim of this study was to assess asthma control and its relation with age, gender, and lung function. Material and methods. A total of 106 family physicians and 13 pulmonologists and allergists took part in this study. Each doctor had selected 10–15 asthma patients and had sent invitations to them by post. On the visit day, the patients themselves filled in the Asthma Control Test. The doctors interviewed the patients and filled in a special questionnaire. Pulmonologists and allergists also assessed lung function by performing spirometry. According to the results of the Asthma Control Test, the disease control level was indicated as “totally controlled” (25 points), “well controlled” (24–20 points), and “uncontrolled” (19 points or less). Results. A total of 876 asthma patients were examined. Uncontrolled asthma was diagnosed to 56.2% of the patients, 36.5% of patients had well controlled and 7.3% totally controlled asthma. There was no significant difference in asthma control level comparing men and women. A correlation between asthma control level and age was found revealing poorer asthma control in older patients. Ninety-five percent of patients were treated with inhaled steroids; most of them had used inhaled steroids in combination with long-acting β2 agonists. It was found that lung function correlated with clinical symptoms of asthma, the demand of shortacting β2 agonists, and asthma control level. Conclusion. The study showed that uncontrolled asthma was diagnosed to more than half of the patients, despite most of them used inhaled steroids. Asthma control was worsening with the age of patients with asthma and it correlated with lung function. We suggest that periodical assessment of asthma control should help to optimize asthma management.
