[Analysis of circumstances of the development of chronic bronchitis in patients treated at Bydgoszcz Lung Disease Clinic in 1993-1996].
The fact, that more than 10% people suffer from COPD /chronic obstructive pulmonary disease/, that number of COPD patients increases rapidly all over the world, and at the moment COPD is one from four the most frequent cause of death, makes us to search for effective methods of prevention and treatment. The number and variety of factors cooperating in pathogenesis and development of the disease in contrast to poor knowledge of them was the reason, that the retrospective analysis of some factors of 300 COPD patients, treated in our Clinic from severe exacerbations was carried out. There were analysed the following factors; age, gender, body mass index, profession, the length and duration of the disease, incidence of exacerbations and habits; alcohol drinking and cigarette smoking. The aim of these searches was to establish the factors which most commonly cooperate in initiation and development of COPD in the province of Bydgoszcz. There was established, that chronic bronchitis was more frequent in men. That deference is caused not only by exposure to occupational irritant factors. COPD was also more frequent in smokers /about 70%/, elders, blue collar workers, especially exposed to irritants and/or toxic effects by virtue of their work, persons living in industrialized Bydgoszcz. There were no correlation between COPD incidence and malnutrition or alcohol consumption, but the simple correlation between time of the disease and severity of airway obstruction was seen. The longer time of chronic bronchitis, the more increased airway obstructions, and more frequent respiratory insufficiency. In the course of the disease was growing; the number of malnutritioned patients and the number of exacerbations of chronic bronchitis. The longer time of disease, the shorter free of symptoms intervals. In alcohol consuming patients the exacerbations occurred significantly more frequent and more severe. There was correlation between alcohol and cigarette consumption. The exacerbations of chronic bronchitis in November, December and March were the most frequently seen. In observed group of chronic bronchitis patients the importance of risk factors unconnected with smoking was significantly great, that suggest the growing role of other factors in pathogenesis and development of COPD.
