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.

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.
