  • Inhaled steroids are associated with reduced lung function decline in subjects with asthma with elevated total IgE
  • 2007

    • 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.

  • Indoor environment in three North European cities in relationship to atopy and respiratory symptoms
  • 2009
  • Ingår i: Clinical Respiratory Journal. - 1752-6981. ; 3:2, s. 85-94
  • Tidskriftsartikel (refereegranskat)abstract
    • In the European Community Respiratory Health Survey (ECRHS) I, the lowest prevalence of asthma and atopy was found in Reykjavik (Iceland)  and Tartu (Estonia). The aim of this study was to compare home environments in Reykjavik and Tartu to a town with a higher prevalence of asthma and atopy (Uppsala, Sweden) in an attempt to identify factors   in the indoor environment that could explain these differences. A random sample of 129 ECRHS II participants was included in this analysis at each of the three study centres. The subjects answered a questionnaire, blood was analysed for specific immunoglobulin E, a   methacholine test was performed and home indoor measurements were taken. The prevalence of atopy was 11.9% in Reykjavik, 35.5% in Uppsala and   28.2% in Tartu (P < 0.04). The level of indoor cat allergen was significantly lower in Reykjavik compared with Uppsala (P = 0.05). No mite allergens were identified in the 41 homes investigated in   Reykjavik, while this was the case in 16% and 72% of the households in Uppsala and Tartu, respectively (P = 0.001). A positive association was found between asthma symptoms and cat allergen levels [odds ratio 1.53 (95% confidence interval 1.04-2.24)], while the levels of viable moulds were significantly associated with increased bronchial responsiveness.   Indoor exposure to allergens, moulds and bacteria was lower in Reykjavik than in the Swedish and Estonian centres. This finding indicates that the lower prevalence of allergic sensitization in Reykjavik may partly be related to lower indoor allergen exposure. Please cite this paper as: Gunnbjornsdottir MI, NorbAck D, Bjornsson E, Soon A, Jarvis D, Jogi R, Gislason D, Gislason T and Janson C.

  • Early life exposures contributing to accelerated lung function decline in adulthood – a follow-up study of 11,000 adults from the general population
  • 2023
  • Ingår i: eClinicalMedicine. - : Elsevier. - 2589-5370. ; 66
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: We aimed to assess whether exposure to risk factors in early life from conception to puberty continue to contribute to lung function decline later in life by using a pooled cohort comprising approx. 11,000 adults followed for more than 20 years and with up to three lung function measurements. Methods: Participants (20–68 years) in the ECRHS and NFBC1966 cohort studies followed in the periods 1991–2013 and 1997–2013, respectively, were included. Mean annual decline in maximum forced expired volume in 1 s (FEV1) and forced vital capacity (FVC) were main outcomes. Associations between early life risk factors and change in lung function were estimated using mixed effects linear models adjusted for sex, age, FEV1, FVC and height at baseline, accounting for personal smoking. Findings: Decline in lung function was accelerated in participants with mothers that smoked during pregnancy (FEV1 2.3 ml/year; 95% CI: 0.7, 3.8) (FVC 2.2 ml/year; 0.2, 4.2), with asthmatic mothers (FEV1 2.6 ml/year; 0.9, 4.4) (FEV1/FVC 0.04 per year; 0.04, 0.7) and asthmatic fathers (FVC 2.7 ml/year; 0.5, 5.0), and in women with early menarche (FVC 2.4 ml/year; 0.4, 4.4). Personal smoking of 10 pack-years contributed to a decline of 2.1 ml/year for FEV1 (1.8, 2.4) and 1.7 ml/year for FVC (1.3, 2.1). Severe respiratory infections in early childhood were associated with accelerated decline among ever-smokers. No effect-modification by personal smoking, asthma symptoms, sex or cohort was found. Interpretation: Mothers’ smoking during pregnancy, parental asthma and early menarche may contribute to a decline of FEV1 and FVC later in life comparable to smoking 10 pack-years.
