- Background: Adult onset asthma is poorly studied and there are few long-term clinical follow-up studies.Aim: To study clinical characteristics of adult onset asthma in a 15-year follow-up.Method: Within the Obstructive Lung Disease in Northern Sweden (OLIN) studies, a cohort of n=309 subjects with adult onset asthma (aged 20-60 years) was recruited during 1995-99. The cohort was followed up in 2012-14 (n=205). Structured interviews and clinical examinations including spirometry were performed at both recruitment and follow-up. Skin prick tests were performed at recruitment and blood samples for cell counts and IgE at the follow-up. Asthma control was classified according to GINA 2006.Results: At follow-up n=182 (89%) still had asthma, while n=23 (11%) were in remission. Among individuals with persistent asthma, mean pre-bronchodilator FEV1 percent of predicted was 89.0 at follow-up, similar as recruitment 88.3. At recruitment 16.5% were smokers, and of these, 86.7% had quit smoking at follow-up. At follow-up, 39% had blood neutrophils ≥4.0x109/L, 23% had blood eosinophils ≥0.3x109/L, and 28% had specific IgE>0.35 IU/ml to any airborne allergen. Any respiratory symptoms were reported by 90% and 31% used medium or high dose inhaled corticosteroids (ICS), 20% low dose ICS whereas 20% had no treatment. 55% had controlled asthma, 32% partly controlled and 13% uncontrolled asthma.Conclusion: In this 15-year follow-up of adult onset asthma, the majority had persistent asthma. Smoking and high proportion using ICS may contribute to the stable lung function. Still, it should be noted that merely around every other had well controlled asthma.

- Background: There are few long-term clinical follow-up studies of adult-onset asthma. The aim of this article was to study clinical characteristics of adult-onset asthma in relation to remission and persistence of the disease in a 15-year follow-up. Methods: A cohort of 309 adults aged 20-60 years with asthma onset during the last 12 months verified by bronchial variability, was recruited between 1995 and 1999 from the general population in northern Sweden. The cohort was followed-up in 2003 (n=250) and between 2012 and 2014 (n=205). Structured interviews and spirometry were performed at recruitment and the follow-ups. Bronchial hyperreactivity (BHR) and skin-prick tests were performed at recruitment and blood samples were collected at the last follow-up. Remission of asthma was defined as no asthma symptoms and no use of asthma medication during the last 12 months. Results: Of eight individuals in remission in 2003, five had relapsed between 2012 and 2014 and in total, 23 (11%) were in remission, while 182 had persistent asthma. Those in remission had higher mean forced expiratory volume in 1 s % predicted at recruitment than those with persistent asthma (94.6 versus 88.3, p=0.034), fewer had severe BHR (27.3% versus 50.9%, p=0.037) and they had less body mass index increase (+1.6 versus +3.0, p=0.054). Of those with persistent asthma, 13% had uncontrolled asthma and they had higher levels of blood neutrophils than those with partly controlled or controlled asthma. Conclusion: Higher forced expiratory volume in 1 s % predicted and less-severe BHR was associated with remission of adult-onset asthma, but still, the proportion in remission in this 15-year follow-up was low.

- PURPOSE: Patient education in chronic obstructive pulmonary disease (COPD) is recommended in treatment strategy documents, since it can improve the ability to cope with the disease. Our aim was to identify the extent of and factors associated with patient education in patients with COPD in a primary health care setting.PATIENTS AND METHODS: In this nationwide study, we identified 29,692 COPD patients with a registration in the Swedish National Airway Register (SNAR) in 2019. Data on patient education and other clinical variables of interest were collected from SNAR. The database was linked to additional national registers to obtain data about pharmacological treatment, exacerbations and educational level.RESULTS: Patient education had been received by 44% of COPD patients, 72% of whom had received education on pharmacological treatment including inhalation technique. A higher proportion of patients who had received education were offered smoking cessation support, had performed spirometry and answered the COPD Assessment Test (CAT), compared with patients without patient education. In the adjusted analysis, GOLD grade 2 (OR 1.29, 95% CI 1.18-1.42), grade 3 (OR 1.41, 95% CI 1.27-1.57) and grade 4 (OR 1.79, 95% CI 1.48-2.15), as well as GOLD group E (OR 1.17, 95% CI 1.06-1.29), ex-smoking (OR 1.70, 95% CI 1.56-1.84) and current smoking (OR 1.45, 95% CI 1.33-1.58) were positively associated with having received patient education, while cardiovascular disease (OR 0.92, 95% CI 0.87-0.98) and diabetes (OR 0.93, 95% CI 0.87-1.00) were negatively associated with receipt of patient education.CONCLUSION: Fewer than half of the patients had received patient education, and the education had mostly been given to those with more severe COPD, ex- and current smokers and patients with fewer comorbidities. Our study highlights the need to enhance patient education at an earlier stage of the disease.

Underdiagnosis and misclassification of COPD in Sweden - A Nordic Epilung study
- 2023
-
Ingår i: Respiratory Medicine. - : Elsevier. - 0954-6111 .- 1532-3064. ; 217
-
Tidskriftsartikel (refereegranskat)abstract
- Introduction: The prevalence of COPD tends to level off in populations with decreasing prevalence of smoking but the extent of underdiagnosis in such populations needs further investigation.Aim: To investigate underdiagnosis and misclassification of COPD with a focus on socio-economy, lifestyle determinants and healthcare utilization.Method: The 1839 participants were selected from two ongoing large-scale epidemiological research programs: The Obstructive Lung Disease in Northern Sweden Studies and the West Sweden Asthma Study. COPDGOLD was defined according to the fixed post-bronchodilator spirometric criteria FEV1/FVC<0.70 in combination with respiratory symptoms. Results: Among the 128 participants who fulfilled the criteria for COPDGOLD, the underdiagnosis was 83.6% (n = 107) of which 57.9% were men. The undiagnosed participants were younger, had higher FEV1% of predicted and less frequently a family history of bronchitis. One in four of the undiagnosed had utilized healthcare and had more frequently utilized healthcare due to a burden of respiratory symptoms than the general population without COPD. Underdiagnosis was not related to educational level. Misclassification of COPD was characterized by being a woman with low education, ever smoker, having respiratory symptoms and having a previous asthma diagnosis.Conclusion: In the high income country Sweden, the underdiagnosis of COPD was highly prevalent. Reduced underdiagnosis can contribute to risk factor modification, medical treatment and self-management strategies in early stages of the disease, which may prevent disease progression and improve the quality of life among those affected. Therefore, there is a need to increase the use of spirometry in primary care to improve the diagnostic accuracy.

Tidskriftsartikel (refereegranskat)abstract
- Background: Chronic airway obstruction (CAO) and restrictive spirometry pattern (RSP) are associated with mortality, but sex-specific patterns of all-cause and specific causes of death have hardly been evaluated. Objectives: To study the possible sex-dependent differences of all-cause mortality and patterns of cause-specific mortality among men and women with CAO and RSP, respectively, to that of normal lung function (NLF). Design: Population-based prospective cohort study. Methods: Individuals with CAO [FEV1/vital capacity (VC) < 0.70], RSP [FEV1/VC >= 0.70 and forced vital capacity (FVC) < 80% predicted] and NLF (FEV1/VC >= 0.70 and FVC >= 80% predicted) were identified within the Obstructive Lung Disease in Northern Sweden (OLIN) studies in 2002-2004. Mortality data were collected through April 2016, totally covering 19,000 patient-years. Cox regression and Fine-Gray regression accounting for competing risks were utilized to estimate hazard ratios (HRs) with 95% confidence intervals (CIs) adjusted for age, body mass index, sex, smoking habits and pack-years. Results: The adjusted hazard for all-cause mortality was higher in CAO and RSP than in NLF (HR, 95% CI; 1.69, 1.31-2.02 and 1.24, 1.06-1.71), and the higher hazards were driven by males. CAO had a higher hazard of respiratory and cardiovascular death than NLF (2.68, 1.05-6.82 and 1.40, 1.04-1.90). The hazard of respiratory death was significant in women (3.41, 1.05-11.07) while the hazard of cardiovascular death was significant in men (1.49, 1.01-2.22). In RSP, the higher hazard for respiratory death remained after adjustment (2.68, 1.05-6.82) but not for cardiovascular death (1.11, 0.74-1.66), with a similar pattern in both sexes. Conclusion: The higher hazard for all-cause mortality in CAO and RSP than in NLF was male driven. CAO was associated with respiratory death in women and cardiovascular death in men, while RSP is associated with respiratory death, similarly in both sexes.

Tidskriftsartikel (refereegranskat)abstract
- BackgroundCOPD has increased in prevalence worldwide over several decades until the first decade after the millennium shift. Evidence from a few recent population studies indicate that the prevalence may be levelling or even decreasing in some areas in Europe. Since the 1970s, a substantial and ongoing decrease in smoking prevalence has been observed in several European countries including Sweden. The aim of the current study was to estimate the prevalence, characteristics and risk factors for COPD in the Swedish general population. A further aim was to estimate the prevalence trend of COPD in Northern Sweden from 1994 to 2009.MethodsTwo large random population samples were invited to spirometry with bronchodilator testing and structured interviews in 2009–2012, one in south-western and one in northern Sweden, n = 1839 participants in total. The results from northern Sweden were compared to a study performed 15 years earlier in the same area and age-span. The diagnosis of COPD required both chronic airway obstruction (CAO) and the presence of respiratory symptoms, in line with the GOLD documents since 2017. CAO was defined as post-bronchodilator FEV1/FVC < 0.70, with sensitivity analyses based on the FEV1/FVC < lower limit of normal (LLN) criterion.ResultsBased on the fixed ratio definition, the prevalence of COPD was 7.0% (men 8.3%; women 5.8%) in 2009–2012. The prevalence of moderate to severe (GOLD ≥ 2) COPD was 3.5%. The LLN based results were about 30% lower. Smoking, occupational exposures, and older age were risk factors for COPD, whereof smoking was the most dominating risk factor. In northern Sweden the prevalence of COPD, particularly moderate to severe COPD, decreased significantly from 1994 to 2009, and the decrease followed a decrease in smoking.ConclusionsThe prevalence of COPD has decreased in Sweden, and the prevalence of moderate to severe COPD was particularly low. The decrease follows a major decrease in smoking prevalence over several decades, but smoking remained the dominating risk factor for COPD.
