- The aim of this study was to investigate the relationship between the effect of emergency treatment and inflammatory markers in patients with acute exacerbations of obstructive pulmonary disease, especially with respect to smoking history. We investigated 50 unselected patients with acute bronchial obstruction. Blood, urine and sputum samples were taken and analysed for eosinophil and neutrophil markers. The patients were observed for at least 2 h and recordings of forced expiratory volume in 1 s (FEV1) were taken. They were re-examined after 1 and 4 weeks. The absolute levels of inflammatory markers did not differ significantly between non- or short-term smokers (< or = 5 pack-years) and long-term smokers (> 5 pack-years) with the exception of myeloperoxidase in serum (S-MPO), which was higher in long-term smokers. The patients with higher levels of eosinophil markers before emergency treatment experienced a greater improvement in lung function. In non- or short-term smokers this relationship was found in blood and urine, whereas in long-term smokers it was seen in sputum. No correlation was found between neutrophil markers and changes in lung function. We conclude that patients with obstructive pulmonary disease with acute exacerbations and high levels of eosinophil markers respond well to treatment.

- Objective: To determine if asthmatic patients who had participated in a 10-week rehabilitation program with emphasis on physical training (1) continued with physical training, (2) maintained their improved cardiovascular condition and lung function, and (3) retained their good asthma control through the following 3 years. Design: A descriptive 3-year follow-up study. Patients and Setting: A convenience sample of 58 patients who had previously undergone a 10-week outpatient rehabilitation program were followed up 6 months and 1, 1.5, 2, and 3 years after the start of the program at a lung clinic in a university hospital. Main Outcome Measures: A training log was kept by each patient to record frequency, intensity, and mode of training. Physical condition was evaluated with a submaximal 6-minute ergometry test and a 12-minute walking test, respiratory function with static and dynamic spirometry, and bronchial hyperreactivity with a metacholine provocation test. Asthma symptoms and asthma control were measured with a study-specific questionnaire. Results: Thirty-nine subjects (68%) exercised regularly during all 3 years. The cardiovascular condition and lung function values remained almost unchanged in all 58 patients. There was a significant decrease in number of emergency room visits the year after the 10-week rehabilitation program compared to the year before. It remained stable throughout the following 2 years. There was also a decrease in asthma symptoms in all patients, but the decrease was significant only in a subgroup of 26 patients, who exercised one or two times a week. Conclusions: It is possible for asthmatic subjects to exercise at a moderate intensity level on a long-term basis without deleterious effects. Moreover, the high compliance rate might indicate that inactive asthmatic patients who are taught how to exercise choose to continue to be physically active.
