- Background A major reason of the poor control of asthma is that patients fail to adhere to their treatment. The aim of the study was to identify factors affecting changes in asthma treatment adherence in an international cohort. Methods A follow-up study was carried out by means of a structured clinical interview in 971 subjects with asthma from 12 countries who participated in both the European Community Respiratory Health Survey: ECRHS-I (1990–94) and ECRHS-II (1998–2002). Subjects were considered adherent if they reported they normally took all the prescribed drugs. A logistic model was used to study the adjusted effect of the determinants. Results The net change in adherence to anti-asthmatic treatment per 10 years of follow-up was −2% (95% CI: −9.5, 5.5), 7.5% (−2.6, 17.6), 15.0% (6.6, 23.5) and 19.8% (4.1, 35.5), respectively, in Nordic, Mediterranean, Continental and extra-European areas. Among the 428 non-adherent subjects in ECRHS-I, having regular consultations with health care professionals was the strongest predictor of increased adherence (OR 3.32; 95% CI: 1.08–10.17). Among the 543 adherent subjects in ECRHS-I, using inhaled corticosteroids significantly predicted a persistence of adherence (OR 2.04; 95% CI: 1.11–3.75). No effect of gender, age, duration of the disease, smoking habit and educational level was observed. Conclusions Our findings highlight the key role of doctors and nurses in educating and regularly reviewing the patients and support the efforts for an improvement of clinical communication.

- We compared risk factors and clinical characteristics, 9-year lung function change and hospitalisation risk across subjects with the asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS), asthma or COPD alone, or none of these diseases. Participants in the European Community Respiratory Health Survey in 1991-1993 (aged 20-44 years) and 1999-2001 were included. Chronic airflow obstruction was defined as pre-bronchodilator forced expiratory volume in 1 s (FEV1)/forced vital capacity

- Rationale: The few prospective studies aimed at assessing the incidence of chronic obstructive pulmonary disease (COPD) in relation to the presence of chronic cough/phlegm have produced contrasting results. Objectives: To assess the incidence of COPD in a cohort of young adults and to test whether chronic cough/phlegm and dyspnea are independent predictors of COPD. Methods: An international cohort of 5,002 subjects without asthma (ages 20-44 yr) with normal lung function (FEV1/FVC ratio ≥ 70%) from 12 countries was followed from 1991-2002 in the frame of the European Community Respiratory Health Survey II. Incident cases of COPD were those who had an FEV 1/FVC ratio less than 70% at the end of the follow-up, but did not report having had a doctor diagnose asthma during the follow-up. Main Results: The incidence rate of COPD was 2.8 cases/1,000/yr (95% confidence interval [CI], 2.3-3.3). Chronic cough/phlegm was an independent and statistically significant predictor of COPD (incidence rate ratio [IRR], 1.85; 95% CI, 1.17-2.93) after adjusting for smoking habits and other potential confounders, whereas dyspnea was not associated with the disease (IRR = 0.98; 95% CI, 0.64-1.50). Subjects who reported chronic cough/phlegm both at baseline and at the follow-up had a nearly threefold-increased risk of developing COPD with respect to asymptomatic subjects (IRR = 2.88; 95% CI, 1.44-5.79). Conclusions: The incidence of COPD is substantial even in young adults. The presence of chronic cough/phlegm identifies a subgroup of subjects with a high risk of developing COPD, independently of smoking habits.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Few studies have investigated the long-term association between inhaled corticosteroids (ICSs) and lung function decline in asthma. OBJECTIVE: To evaluate whether prolonged treatment with ICSs is associated with FEV(1) decline in adults with asthma. METHODS: An international cohort of 667 subjects with asthma (20-44 years old) was identified in the European Community Respiratory Health Survey (1991-1993) and followed up from 1999 to 2002. Spirometry was performed on both occasions. FEV(1) decline was analyzed according to age, sex, height, body mass index, total IgE, time of ICS use, and smoking, while adjusting for potential confounders. RESULTS: As ICS use increased, the decline in FEV(1) was lower (P trend = .025): on average, decline passed from 34 mL/y in nonusers (half of the sample) to 20 mL/y in subjects treated for 48 months or more (18%). When adjusting for all covariates, there was an interaction (P = .02) between ICS use and total IgE: in subjects with high (>100 kU/L) IgE, ICS use for 4 years or more was associated with a lower FEV(1) decline (23 mL/y; 95% CI, 8-38 compared with nonusers). This association was not seen in those with lower IgE. CONCLUSION: Although confirming a beneficial long-term association between ICSs and lung function in asthma, our study suggests that subjects with high IgE could maximally benefit from a prolonged ICS treatment. CLINICAL IMPLICATIONS: This study adds further evidence to the beneficial effect of inhaled steroids on lung function in asthma; future studies will clarify whether calibrating the corticosteroid dose according to the level of total IgE is a feasible approach in asthma management.

- Rationale: Few studies have investigated the factors associated with the early inception of chronic obstructive pulmonary disease (COPD). Objectives: We investigated COPD risk factors in an international cohort of young adults using different spirometric definitions of the disease. Methods. We studied 4,636 subjects without asthma who had prebronchodilator FEV1/FVC measured in the European Community Respiratory Health Survey both in 1991 to 1993 (when they were 20-44 yr old) and in 1999 to 2002. COPD was defined according to the Global Initiative for Chronic Obstructive Lung Disease fixed cut-off criterion (FEV1/FVC < 0.70), and two criteria based on the Quanjer and LuftiBus reference equations (FEV1/FVC less than lower limit of normal). COPD determinants were studied using two-level Poisson regression models. Measurements and Main Results: COPD incidence ranged from 1.85 (lower limit of normal [Quanjer]) to 2.88 (Global Initiative for Chronic Obstructive Lung Disease) cases/1,000/yr. Although about half of the cases had smoked less than 20 pack-years, smoking was the main risk factor for COPD, and it accounted for 29 to 39% of the new cases during the follow-up. Airway hyperresponsiveness was the second strongest risk factor (15-17% of new cases). Other determinants were respiratory infections in childhood and a family history of asthma, whereas the role of sex, age, and of being underweight largely depended on the definition of COPD used. Conclusions: COPD may start early in life. Smoking prevention should be given the highest priority to reduce COPD occurrence. Airway hyperresponsiveness, a family history of asthma, and respiratory infections in childhood are other important determinants of COPD. We suggest the need for a definition of COPD that is not exclusively based on spirometry.

- BACKGROUND: Inhaled corticosteroids have been widely used for the regular treatment of asthma and COPD over the past few decades. To date, studies investigating the effects of ICS on bone in populations including asthma and COPD patients, show conflicting results. The skeletal effects of ICS remain poorly understood. We assessed the association between ICS exposure and self-reported osteoporosis diagnosis in a European cohort study.METHODS: The analysis was carried out by using clinical and questionnaire data available for subjects participating in the ECRHS III (European Community Respiratory Health Survey) with age >55 years.RESULTS: Among the 3004 enrolled subjects, 245 were ICS users with an exposure ≥12 months. Osteoporosis was reported by 16 subjects in the ICS group (6.5%) and by 167 in the not exposed group (6.1%). The adjusted risk of osteoporosis in ICS users (≥12 months) was not greater in exposed subjects when compared with the unexposed ones (OR=1.02, 95CI%: 0.51, 2.03). The same result was observed even when considering in the analysis a longer exposure to the ICS use (≥ 36.5 months, the median ICS exposure for all subjects). History of COPD, use of oral corticosteroids, Body Mass Index, smoking and physical activity did not show any evidence of an association with osteoporosis.CONCLUSIONS: Our study did not show any significant association between long- term ICS use and self-reported diagnosis of osteoporosis in subjects aged >55 years. To explore the real effect of ICS on bone status, further studies are needed, especially in the long-term ICS exposure.

- Asthma often remains uncontrolled, despite the fact that the pharmacological treatment has undergone large changes. We studied changes in the treatment of asthma over a 20-year period and identified factors associated with the regular use of inhaled corticosteroid (ICS) treatment. Changes in the use of medication were determined in 4617 randomly selected subjects, while changes in adults with persistent asthma were analysed in 369 participants. The study compares data from three surveys in 24 centres in 11 countries. The use of ICSs increased from 1.7% to 5.9% in the general population and the regular use of ICSs increased from 19% to 34% among persistent asthmatic subjects. The proportion of asthmatic subjects reporting asthma attacks in the last 12 months decreased, while the proportion that had seen a doctor in the last 12 months remained unchanged (42%). Subjects with asthma who had experienced attacks or had seen a doctor were more likely to use ICSs on a regular basis. Although ICS use has increased, only one-third of subjects with persistent asthma take ICSs on a regular basis. Less than half had seen a doctor during the last year. This indicates that underuse of ICSs and lack of regular healthcare contacts remains a problem in the management of asthma.
