- Background Smoking is the main risk factor for most of the leading causes of death. Cessation is the single most important step that smokers can take to improve their health. With the aim of informing policy makers about decisions on future tobacco control strategies, we estimated time and age trends in smoking cessation in Europe between 1980 and 2010. Methods Data on the smoking history of 50,228 lifetime smokers from 17 European countries were obtained from six large population-based studies included in the Ageing Lungs in European Cohorts (ALEC) consortium. Smoking cessation rates were assessed retrospectively, and age trends were estimated for three decades (1980-1989, 1990-1999, 2000-2010). The analyses were stratified by sex and region (North, East, South, West Europe). Results Overall, 21,735 subjects (43.3%) quit smoking over a total time-at-risk of 803,031 years. Cessation rates increased between 1980 and 2010 in young adults (16-40 years), especially females, from all the regions, and in older adults (41-60 years) from North Europe, while they were stable in older adults from East, South and West Europe. In the 2000s, the cessation rates for men and women combined were highest in North Europe (49.9 per 1,000/ year) compared to the other regions (range: 26.5-32.7 per 1,000/ year). A sharp peak in rates was observed for women around the age of 30, possibly as a consequence of pregnancy-related smoking cessation. In most regions, subjects who started smoking before the age of 16 were less likely to quit than those who started later. Conclusions Our findings suggest an increasing awareness on the detrimental effects of smoking across Europe. However, East, South and West European countries are lagging behind North Europe, suggesting the need to intensify tobacco control strategies in these regions. Additional efforts should be made to keep young adolescents away from taking up smoking, as early initiation could make quitting more challenging during later life.

Journal article (peer-reviewed)abstract
- Background: This study is aimed at providing a real-world evaluation of the economic cost of persistent asthma among European adults according to the degree of disease control [as defined by the 2006 Global Initiative for Asthma (GINA) guidelines]. Methods: A prevalence-based cost-of-illness study was carried out on 462 patients aged 30-54 years with persistent asthma (according to the 2002 GINA definition), who were identified in general population samples from 11 European countries and examined in clinical settings in the European Community Respiratory Health Survey II between 1999 and 2002. The cost estimates were computed from the societal perspective following the bottom-up approach on the basis of rates, wages and prices in 2004 (obtained at the national level from official sources), and were then converted to the 2010 values. Results: The mean total cost per patient was EUR 1,583 and was largely driven by indirect costs (i.e. lost working days and days with limited, not work-related activities 62.5%). The expected total cost in the population aged 30-54 years of the 11 European countries was EUR 4.3 billion (EUR 19.3 billion when extended to the whole European population aged from 15 to 64 years). The mean total cost per patient ranged from EUR 509 (controlled asthma) to EUR 2,281 (uncontrolled disease). Chronic cough or phlegm and having a high BMI significantly increased the individual total cost. Conclusions: Among European adults, the cost of persistent asthma drastically increases as disease control decreases. Therefore, substantial cost savings could be obtained through the proper management of adult patients in Europe.

Journal article (peer-reviewed)abstract
- Background: Epidemiologic evidence related to asthma control in patients from the general population is scanty. Objectives: We sought to assess asthma control in several European centers according to the Global Initiative for Asthma (GINA) guidelines and to investigate its determinants. Methods: In the European Community Respiratory Health Survey 11 (1999-2002), 1241 adults with asthma were identified and classified into inhaled corticosteroid (ICS) users and non-ICS users in the last year. Control was assessed in both groups by using the GINA proposal (controlled, partly controlled, and uncontrolled asthma), and it was related to potential determinants. Results: Only 15% (95% CI, 12% to 19%) of subjects who had used ICSs in the last year and 45% (95% CI, 41% to 50%) of non-ICS users had their asthma under control; individuals with uncontrolled asthma accounted for 49% (95% CI, 44% to 53%) and 18% (95% CI, 15% to 21%), respectively. Among ICS users, the prevalence of uncontrolled asthma showed great variability across Europe, ranging from 20% (95% CI, 7% to 41%; Iceland) to 67% (95% CI, 35% to 90%; Italy). Overweight status, chronic cough and phlegm, and sensitization to Cladosporium species were associated with poor control in ICS users. About 65% and 87% of ICS users with uncontrolled and partly controlled asthma, respectively, were on a medication regimen that was less than recommended by the GINA guidelines. Conclusion: Six of 7 European asthmatic adults using ICSs in the last year did not achieve good disease control. The large majority of subjects with poorly controlled asthma were using antiasthma drugs in a suboptimal way. A wide variability in asthma control emerged across Europe. Clinical implications: Greater attention should be paid to asthma management and to the implementation of the GINA guidelines.

- 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.

Atopy Modifies the Association Between Inhaled Corticosteroid Use and Lung Function Decline in Patients with Asthma
- 2020
-
In: Journal of Allergy and Clinical Immunology. - : ELSEVIER. - 2213-2198 .- 2213-2201. ; 8:3, s. 980-
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Inhaled corticosteroids (ICSs) are the mainstay of asthma treatment, but response to medication is variable. Patients with allergic inflammation generally show a better short-term response to ICSs; however, studies on predictors of long-term response are few. OBJECTIVE: To assess whether allergic sensitization can modify the association between ICS use and lung function decline over 20 years in adult asthma. METHODS: We used data from the 3 clinical examinations of the European Community Respiratory Health Survey. We measured ICS use (no use, and use for <1.3, 1.3-8, and >8 years) and FEV1 decline among subjects with asthma over the 2 periods between consecutive examinations. We conducted a cohort study combining data of the 2 periods (906 observations from 745 subjects) to assess whether the association between ICS use and FEV1 decline was modified by allergic sensitization (IgE > 0.35 kU/L for any of house-dust mite, timothy grass, cat, or Cladosporium). RESULTS: FEV1 decline was similar for non-ICS users, as well as ICS users for less than 1.3 years, with and without allergic sensitization. However, among subjects on ICSs for a longer period, sensitization was associated with an attenuated decline (P-interaction = .006): in the group treated for more than 8 years, FEV1 decline was on average 27 mL/y (95% CIBonferroni-adjusted, 11-42) lower for subjects with sensitization compared with nonsensitized subjects. CONCLUSIONS: Our study suggests that biomarkers of atopy can predict a more favorable long-term response to ICSs. Randomized controlled studies are needed to confirm these findings.

- 2021

Journal article (peer-reviewed)abstract
- Background: Fractional exhaled nitric oxide (FeNO) is a marker of type-2 inflammation used both to support diagnosis of asthma and follow up asthma patients. The associations of FeNO with lung function decline and bronchodilator (BD) response have been studied only scarcely in large populations.Objectives: To study the association between FeNO and a) retrospective lung function decline over 20 years, and b) lung function response to BD among asthmatic subjects compared with non-asthmatic subjects and with regards to current smoking and sex.Methods: Longitudinal analyses of previous lung function decline and FeNO level at follow-up and cross-sectional analyses of BD response and FeNO levels in 4257 participants (651 asthmatics) from the European Community Respiratory Health Survey.Results: Among asthmatic subjects, higher percentage declines of FEV1 and FEV1/FVC were associated with higher FeNO levels (p = 0.001 for both) at follow-up. These correlations were found mainly among non-smoking individuals (p = 0.001) and females (p = 0.001) in stratified analyses.Percentage increase in FEV1 after BD was positively associated with FeNO levels in non-asthmatic subjects. Further, after stratified for sex and smoking separately, a positive association was seen between FEV1 and FeNO levels in non-smokers and women, regardless of asthma status.Conclusions: We found a relationship between elevated FeNO and larger FEV1 decline over 20 years among subjects with asthma who were non-smokers or women. The association between elevated FeNO levels and larger BD response was found in both non-asthmatic and asthmatic subjects, mainly in women and non-smoking subjects.

Journal article (peer-reviewed)abstract
- BACKGROUND: Previous studies have reported an association between weight increase and excess lung function decline in young adults followed for short periods. We aimed to estimate lung function trajectories during adulthood from 20-year weight change profiles using data from the population-based European Community Respiratory Health Survey (ECRHS).METHODS: We included 3673 participants recruited at age 20-44 years with repeated measurements of weight and lung function (forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1)) in three study waves (1991-93, 1999-2003, 2010-14) until they were 39-67 years of age. We classified subjects into weight change profiles according to baseline body mass index (BMI) categories and weight change over 20 years. We estimated trajectories of lung function over time as a function of weight change profiles using population-averaged generalised estimating equations.RESULTS: In individuals with normal BMI, overweight and obesity at baseline, moderate (0.25-1 kg/year) and high weight gain (>1 kg/year) during follow-up were associated with accelerated FVC and FEV1 declines. Compared with participants with baseline normal BMI and stable weight (±0.25 kg/year), obese individuals with high weight gain during follow-up had -1011 mL (95% CI -1.259 to -763) lower estimated FVC at 65 years despite similar estimated FVC levels at 25 years. Obese individuals at baseline who lost weight (<-0.25 kg/year) exhibited an attenuation of FVC and FEV1 declines. We found no association between weight change profiles and FEV1/FVC decline.CONCLUSION: Moderate and high weight gain over 20 years was associated with accelerated lung function decline, while weight loss was related to its attenuation. Control of weight gain is important for maintaining good lung function in adult life.
