Comorbidities as an element of multidimensional prognostic assessment of patients with chronic obstructive pulmonary disease.
Chronic obstructive pulmonary disease (COPD) is characterized by chronic airflow limitation, some significant extrapulmonary effects, and important comorbidities. The BODE index, a multidimensional scale, has been proposed to better identify severity of the disease and to predict survival. The goal of the study was to evaluate the prevalence of concomitant diseases in patients with COPD and to assess correlations between comorbidities and the BODE index. ⋯ We also found that patients with higher BODE scores had more exacerbations of COPD. Comorbidities are very common in COPD. Results indicate a close connection between the BODE index and some comorbidities, which suggests that these conditions may aggravate the COPD course and increase risk of mortality.

Case ReportsTherapeutic approach to a child with acute respiratory distress syndrome: a report of two cases.
The course of a respiratory disorder in a child may end up in respiratory failure. There are also acute non-respiratory diseases which have a great influence on the respiratory functions and often lead to the acute lung injury and sometimes to the acute respiratory distress syndrome (ARDS). A feature of respiratory function deterioration is changed in the surfactant system. ⋯ Despite many recently published studies explaining the principle of this disorder, the mortality of ARDS is still very high (30-50%). There are several studies documenting successful administration of exogenous surfactant as part of a complex combined therapy of patients with ARDS, which leads to decreased mortality, improved oxygenation, and decreased need for aggressive artificial pulmonary ventilation. The authors of this article present their own experience with administration of exogenous surfactant in therapy of children with ARDS.

Comparative StudyComparison of cellular and biochemical markers of airway inflammation in patients with mild-to-moderate asthma and chronic obstructive pulmonary disease: an induced sputum and bronchoalveolar lavage fluid study.
Although the clinical pictures of asthma and chronic obstructive pulmonary disease (COPD) may be similar, the pathogenesis differs in many aspects. The aim of the present study was to compare the cellular and biochemical features of airway inflammation in patients with asthma and COPD. The study was conducted in 22 patients with asthma (M/F 12/10, mean age 36 +/-14 years) and 17 patients with COPD (M/F 10/7, mean age 57 +/-11 years). ⋯ The BALF concentration of MPO was significantly higher in patients with COPD compared with asthma patients. We conclude that the comparison of cellular composition and the concentration of inflammatory mediators in IS does not differentiate between asthma and COPD. The evaluation of BALF reveals more differences in the cellular and biochemical features of airways inflammation in patients with asthma and COPD than that of IS.

The influence of obesity on sleep quality in male sleep apnea patients before and during therapy.
Evidence exists that obesity, even in the absence of sleep related respiratory disorders, affects sleep negatively. In this study we examined the influence of obesity on sleep quality of male sleep apnea patients before and after breathing normalization with continuous positive airway pressure (CPAP). We compared the polysomnography from the diagnostic night, second night with CPAP, and a control night (three months later) in 13 non-obese, 13 obese, and 12 severely obese male obstructive sleep apnea patients. ⋯ In the second night under CPAP, normalization of the AHI and a rebound of REM and SWS occurred, which was more pronounced in severely obese than in the non-obese and obese group. The polysomnography recorded three months thereafter revealed no differences in sleep stages between the groups. We conclude that after the long-term CPAP therapy, no effect of obesity on sleep quality is apparent.

Concentration of matrix metalloproteinase-9 in serum of patients with chronic obstructive pulmonary disease and a degree of airway obstruction and disease progression.
Chronic obstructive pulmonary disease (COPD) is chronic inflammation leading to irreversible airway obstruction. Previous studies showed increased metalloproteinases (MMP) level, especially MMP-9, as a sign of local inflammation. Up-to-date, only a few studies estimated the MMP-9 serum concentration in COPD with respect to correlation with systemic inflammation. ⋯ In the COPD group, the MMP-9 levels were negatively correlated with FEV1 (P=0.01) and FEV1/FVC (P=0.0002). In conclusion, the results suggest that MMP-9 plays an important role in systemic inflammation in COPD. Higher MMP-9 serum concentration is connected with higher airway obstruction and disease progression.
