- Do markers of eosinophil activation differ in their ability to detect subjects with atopy or bronchial hyper-responsiveness (BHR)? Comparisons of serum levels of eosinophil peroxidase (S-EPO), of eosinophil cationic protein (S-ECP) and the blood eosinophil count (B-Eos) have been made between 154 subjects aged 20-44 years, participating in the European Community Respiratory Health Survey in Uppsala, Sweden. Subjects with atopy had significantly higher levels of S-EPO and S-ECP than those without atopy (P <0 center dot 001). Subjects with BHR had significantly higher levels of S-EPO (P <0 center dot 001) and B-Eos (P <0 center dot 01) than subjects without BHR. Persons reporting asthma-related symptoms had significantly higher levels of S-EPO and B-Eos than subjects without such symptoms (P <0 center dot 001 and P <0 center dot 01, respectively). Asthma symptom score correlated significantly to S-EPO (r = 0 center dot 26, P <0 center dot 01), S-ECP (r = 0 center dot 20, P <0 center dot 05) and B-Eos (r = 0 center dot 18, P <0 center dot 05). Finally, S-EPO was significantly more sensitive than S-ECP for detecting subjects with BHR (P <0 center dot 05) and significantly more sensitive than B-Eos for detecting both subjects with BHR and subjects with a combination of atopy and BHR (P <0 center dot 05). It is concluded that S-EPO is a promising marker with a higher sensitivity for BHR than S-ECP or B-Eos. Further studies are needed to define the value of S-EPO when following disease activity.

- 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.

Symptoms related to snoring and sleep apnoea in subjects with chronic bronchitis : report from the Obstructive Lung Disease in Northern Sweden study

- To assess the relationship between chronic bronchitis and obstructive sleep apnoea, a postal survey was performed. A postal questionnaire was sent to 523 subjects identified as having chronic bronchitis or long-standing cough and sputum production in the Obstructive Lung Disease in Northern Sweden Study I (OLIN I). In 1986-88, all 6610 adults born in 1919-20, 1934-35 and 1949-50 living in representative areas in Northern Sweden were screened for airway diseases according to different methods. A random sample of healthy adults identified in the screening were chosen as references (n = 625). Subjects were asked about a variety of airway symptoms, smoking habits and symptoms related to obstructive sleep apnoea syndrome (OSAS). In the bronchitic group, 20% did not report bronchitic symptoms in the present study, and 26% of the formerly healthy reference group reported at least one bronchitic symptom in the present study. Snoring, apnoea and liability to 'nod off' during activity were much more common in the bronchitic group in both men and women, and most common in men, as expected. Snoring was reported by 29% of the men in the bronchitic group and by 14% in the reference group. In women, the corresponding figures were 14 and 8%, respectively, and for apnoea, the figures were 25 vs. 11% in men and 6 vs. 4% in women. The prevalence of OSAS symptoms was similar in subjects with attacks of breathlessness, long-standing cough, sputum production and recurrent wheezing. Bronchitic symptoms may influence quality of sleep and contribute to daytime tiredness, but this does not fully explain the high prevalence of snoring and apnoea reported by subjects in this cohort. This study indicates a positive correlation between chronic bronchitis and OSAS, but sleep studies are required to confirm this
