Pharmacological treatment of asthma in Sweden from 2005 to 2015.

OBJECTIVE: Despite access to effective therapies many asthma patients still do not have well-controlled disease. This is possibly related to underuse of inhaled corticosteroids (ICS) and overuse of short-acting ß2-agonists (SABA). Our aim was to investigate longitudinal trends and associated factors in asthma treatment. METHODS: Two separate cohorts of adults with physician-diagnosed asthma were randomly selected from 14 hospitals and 56 primary health centers in Sweden in 2005 (n = 1182) and 2015 (n = 1225). Information about symptoms, maintenance treatment, and use of rescue medication was collected by questionnaires. Associations between treatment and sex, age, smoking, education, body mass index (BMI), physical activity, allergic asthma, and symptom control were analyzed using Pearson's chi2-test. Odds ratios (ORs) were calculated using logistic regression. RESULTS: Maintenance treatment with ICS together with long-acting ß2-agonists (LABA) and/or montelukast increased from 39.2% to 44.2% (p = 0.012). The use of ICS + LABA as-needed increased (11.1-18.9%, p < 0.001), while SABA use decreased (46.4- 41.8%, p = 0.023). Regular treatment with ICS did not change notably (54.2-57.2%, p = 0.14). Older age, former smoking, and poor symptom control were related to treatment with ICS + LABA/montelukast. In 2015, 22.7% reported daily use of SABA. A higher step of maintenance treatment, older age, obesity, shorter education, current smoking, allergic asthma, low or very high physical activity, and a history of exacerbations were associated with daily SABA use. CONCLUSIONS: The use of ICS + LABA both for maintenance treatment and symptom relief has increased over time. Despite this, the problem of low use of ICS and high use of SABA remains.

Socioeconomic status, lifestyle factors and asthma prevalence: results from a population-based study in Sweden.

AIM: To examine differences in the prevalence of self-reported diagnosed asthma by socioeconomic status and the contribution of lifestyle factors to these differences. METHODS: The study was based on 28,531 persons aged 18 years or older who answered a survey questionnaire sent to a random population sample in mid-Sweden in 2017. The overall response rate was 44%. Socioeconomic status was measured with educational level and economic difficulties, and lifestyle factors with physical activity, smoking, snuff use, risk-drinking of alcohol and obesity. The associations between socioeconomic status and asthma were analysed using multivariate logistic regression. RESULTS: The overall asthma prevalence was 9% among women and 7% in men and decreased with increasing age. Educational level was not independently associated with asthma, but a statistically significant odds ratio (with 95% confidence intervals) for the prevalence of asthma was observed for economic difficulties 1.5 (1.3-1.7). Also, physical inactivity 1.2 (1.1-1.3) and obesity 1.6 (1.4-1.8) were associated with increased asthma prevalence. Smoking and risk-drinking were not statistically significantly associated with asthma whereas snuff users had a higher prevalence of asthma among women. Adjusting for lifestyle factors did not affect the association between socioeconomic status and asthma. CONCLUSIONS: In this population-based study, self-reported diagnosed asthma was independently associated with economic difficulties but not with educational level. Lifestyle factors did not explain the association between economic difficulties and asthma prevalence. This applies to both men and women as well as younger and older age groups.

Quality of life and asthma control related to hormonal transitions in women's lives.

OBJECTIVES: The aim was to investigate if menstruation and use of exogenous sex hormones influence self-reported asthma related quality of life (QoL) and asthma control. METHODS: The study is based on two asthma cohorts randomly selected in primary and secondary care. A total of 622 female patients 18-65 years were included and classified as premenopausal ≤ 46 years (n = 338) and peri/postmenopausal 47-65 years (n = 284). Questionnaire data from 2012 and 2014 with demographics, asthma related issues and sex hormone status. Outcome measures were Mini Asthma Quality of Life Questionnaire (Mini-AQLQ) and asthma control including Asthma Control Test (ACT) and exacerbations last six months. RESULTS: Premenopausal women with menstruation related asthma worsening, perimenstrual asthma (PMA) (9%), had a clinically relevant lower Mini-AQLQ mean score 4.9 vs. 5.8 (p < 0.001), lower asthma control with ACT score < 20, 72% vs. 28% (p < 0.001) and higher exacerbation frequency 44% vs. 20% (p = 0.004) compared with women without PMA. Women with irregular menstruation had higher exacerbation frequency than women with regular menstruation (p = 0.023). Hormonal contraceptives had no impact on QoL and asthma control. Peri/postmenopausal women with menopausal hormone therapy (MHT) had a clinically relevant lower Mini-AQLQ mean score compared to those without MHT, 4.9 vs 5.4 (p < 0.001), but no differences in asthma control. CONCLUSION: Women with PMA had lower QoL and more uncontrolled asthma than women without PMA. Peri/postmenopausal women with MHT had lower QoL than women without MHT. Individual clinical management of women with asthma may benefit from information about their sex hormone status.

Exploration of the feasibility to combine patients with chronic obstructive pulmonary disease and chronic heart failure in self-management groups with focus on exercise self-efficacy.

OBJECTIVE: To compare the level of exercise self-efficacy, symptoms, functional capacity and health status and investigate the association between these variables in patients with chronic obstructive pulmonary disease (COPD) and chronic heart failure (CHF). Additionally, to investigate how diagnosis, symptoms and patient characteristics are associated with exercise self-efficacy in these patient groups. DESIGN: Cross-sectional study. SETTING: Primary care. SUBJECTS: Patients (n = 150) with COPD (n = 60), CHF (n = 60) and a double diagnosis (n = 30). MAIN OUTCOME MEASURES: Swedish SCI Exercise Self-Efficacy score, modified Medical Research Council Dyspnea score (mMRC), fatigue score, pain severity score, Hospital Anxiety and Depression Scale, functional capacity measured as six-minute walking distance and health status measured by a Visual Analogue Scale. RESULTS: Levels of exercise self-efficacy, health status and symptoms were alike for patients with COPD and patients with CHF. Functional capacity was similar after correction for age. Associations with exercise self-efficacy were found for slight dyspnea (mMRC = 1) (R -4.45; 95% CI -8.41- -0.50), moderate dyspnea (mMRC = 2) (-6.60;-10.68- -2.52), severe dyspnea (mMRC ≥ 3) (-9.94; -15.07- -4.80), fatigue (-0.87;-1.41- -0.32), moderate pain (-3.87;-7.52- -0.21) and severe pain (-5.32;-10.13- -0.52), symptoms of depression (-0.98;-1.42- -0.55) and anxiety (-0.65;-0,10- -0.32), after adjustment for diagnosis, sex and age. CONCLUSION AND IMPLICATIONS: Patients with COPD or CHF have similar levels of exercise self-efficacy, symptoms, functional capacity and health status. More severe symptoms are associated with lower levels of exercise self-efficacy regardless of diagnosis, sex and age. When forming self-management groups with a focus on exercise self-efficacy, it seems more relevant to consider level of symptoms than the specific diagnosis of COPD or CHF.Key pointsExercise training is an important part of self-management in patients with COPD and chronic heart failure (CHF). High exercise self-efficacy is required for optimal exercise training.Patients with COPD and CHF have similar symptoms and similar levels of exercise self-efficacy, functional capacity and health status.Not the diagnosis, but symptoms of dyspnea, fatigue, pain, depression and anxiety are important factors influencing exercise self-efficacy and need to be addressed.When forming self-management groups with a focus on exercise self-efficacy, it seems more relevant to consider the level of symptoms than the specific diagnosis of COPD or CHF.

Factors associated with knowledge of self-management of worsening asthma in primary care patients: a cross-sectional study.

OBJECTIVE: Self-management is important for asthma control. We examined associations of patient- and healthcare-related factors with self-reported knowledge of self-management of worsening asthma. METHODS: Two asthma patient cohorts from 2012 (n = 527) and 2015 (n = 915) were randomly selected from 54 primary health care centers (PHCC) in central Sweden. Data were collected using patient questionnaires and questionnaires to the PHCCs. Logistic regression analyzed associations of relevant variables with knowledge of self-management of worsening asthma. RESULTS: In total, 63% of patients reported moderate to complete knowledge of self-management procedures. The adjusted OR for moderate to complete knowledge relative to high education level was 1.38 [95% CI 1.03-1.85)]; for physician continuity 2.19 (95% CI 1.62-2.96); for a written action plan 11.9 (95% CI 6.16-22.9); for Step 2 maintenance treatment 1.53 (95% CI 0.04-2.24); and 2.07 (95% CI 1.44-2.99) for Step 3. An asthma/COPD nurse visit within the previous 12 months was associated with greater knowledge in women but not in men (p for interaction = 0.042). Smoking [OR 0.56 (95% CI 0.34-0.95)], co-morbidities ≥1 [OR 0.68 (95% CI 0.49-0.93)], and self-rated moderate/severe disease [OR 0.68 (95% CI 0.51-0.90)] were associated with low self-management knowledge. CONCLUSION: Self-reported knowledge of self-management procedures was associated with a higher educational level, physician continuity, a written action plan, advanced treatment and, in women, visiting an asthma/COPD nurse. The results reinforce the importance of implementing guidelines of patient access to a specific physician, a written action plan, and structured education by an asthma/COPD nurse.

A complex intervention of self-management for patients with COPD or CHF in primary care improved performance and satisfaction with regard to own selected activities; A longitudinal follow-up.

AIM: To test a self-management intervention in primary health care (PHC) for patients with chronic obstructive pulmonary disease (COPD) or chronic heart failure (CHF) on self-efficacy, symptoms, functioning, and health. BACKGROUND: Patients with COPD or CHF experience often the same symptoms such as shortness of breath, cough, lack of energy, dry mouth, numbness or tingling in hands and feet, pain and sleeping problems. DESIGN: A multicentre randomized control trial. METHOD: The trial was conducted with one intervention group (N = 73) and one control group (N = 77). The trial was performed from September 2013-September 2015 at nine PHC centres in three county councils in Sweden. At baseline patients with COPD and CHF experienced any symptom. Follow-ups were performed after 3 months and 1 year. The intervention was structured on Bandura's theory of self-efficacy in six meetings and individual action plans based on personal problems were performed and discussed. RESULTS: At baseline, there were no differences between the groups except for SF-36 social function. After 3 months, the intervention group improved performance and satisfaction with regard to own selected activities, otherwise no differences were found. CONCLUSION: When designing a program, the patient's own difficulties must be taken into consideration if person-centred care is to be established. It is feasible to include both patients with COPD and CHF in the same group in PHC. Healthcare professionals need supervision in pedagogics during intervention in self-management.

The Increased Burden of Morbidity Over the Life-Course Among Patients with COPD: A Register-Based Cohort Study in Sweden.

Purpose: Patients with a diagnosis of chronic obstructive pulmonary disease (COPD) often have other chronic disorders. This study aims to describe the life-course pattern of morbidity in patients with COPD. Patients and Methods: Among all residents aged 50-90 years in Sweden in 1997, people with a hospital COPD diagnosis were identified using Swedish national registers (1997-2018). Each patient with COPD was matched by sex, birthyear and county of residency with up to five COPD-free controls. Other chronic disease diagnoses were identified during 1987-2018. Conditional logistic regression calculated risk of diseases diagnosed prior to first COPD diagnosis, producing odds ratios (OR) and 95% confidence intervals (95% CI). Cox regression estimated risk of diagnoses after first COPD diagnosis, producing hazard ratios (HR) and 95% CI. Results: Among 2,706,814 individuals, 225,159 (8.3%) had COPD. The nested case-control sample included 223,945 COPD-cases with 1,062,731 controls. Prior to first COPD diagnosis, future COPD patients had higher risks than controls for most examined conditions. Highest risks were seen for chronic heart failure (OR = 3.25, 3.20-3.30), peripheral arterial disease (OR = 3.12, 3.06-3.18) and lung cancer (OR = 12.73, 12.12-13.37). Following the COPD diagnosis, individuals with COPD had higher risks of most conditions than individuals without COPD. Chronic heart failure (HR = 3.50, 3.46-3.53), osteoporosis (HR = 3.35, 3.30-3.42), depression (HR = 2.58, 2.53-2.64) and lung cancer (HR = 6.04, 5.90-6.18) predominated. The risk of vascular dementia was increased after COPD diagnosis (HR = 1.53, 1.48-1.58) but not Alzheimer's disease. Conclusion: Accumulation of chronic morbidity may precede COPD. Following the diagnosis, an increased burden of cardiovascular disease and cancer is to be expected, but subsequent depression, osteoporosis, and vascular dementia should also be noted. Management strategies for patients with COPD should consider the higher-than-average risk of multimorbidity.

Risk Factors Associated with Asthma Control and Quality of Life in Patients with Mild Asthma Without Preventer Treatment, a Cross-Sectional Study.

Purpose: To study risk factors for uncontrolled asthma and insufficient quality of life (QoL) in patients with mild asthma, ie those without preventer treatment. Patients and Methods: Patients aged 18-75 years with a doctor's diagnosis of asthma randomly selected from primary and secondary care in Sweden. Mild asthma was defined as self-reported current asthma and no preventer treatment. Data were collected from self-completed questionnaires in 2012 and 2015. Well-controlled asthma was defined as Asthma Control Test (ACT) ≥20 points and no exacerbation and uncontrolled asthma as ACT<20 points and/or at least one exacerbation in the previous six months. QoL was measured by the Mini Asthma Quality of Life Questionnaire (Mini-AQLQ), where a total mean score of ≥ 6 indicated sufficient and < 6 insufficient QoL. Multivariate logistic regression analyses were performed using asthma control and Mini-AQLQ as dependent variables. Asthma control was dichotomized as controlled and uncontrolled asthma and the Mini-AQLQ as sufficient QoL (mean score ≥6) and insufficient QoL (mean score <6). Results: Among 298 patients, 26% had uncontrolled asthma, 40% insufficient QoL and 20% both uncontrolled asthma and insufficient QoL. Age ≥60 years, obesity, daily smoking, rhinitis and inadequate knowledge of asthma self-management were independently associated with poor asthma control. Factors independently associated with insufficient QoL were age ≥60 years, overweight, obesity, rhinitis, sinusitis and inadequate knowledge of asthma self-management. Age ≥60 years, obesity, rhinitis and inadequate knowledge of asthma self-management were independently associated with both uncontrolled asthma and insufficient QoL. Conclusion: Among asthma patients without preventer medication, 26% had uncontrolled asthma and 40% had insufficient asthma-related QoL. Older age, obesity, and rhinitis were risk factors for both poor asthma control and a reduced QoL, but having good knowledge of asthma self-management reduced this risk. Our findings suggest that this group of patients requires further attention and follow-up.

Many patients with little symptoms of asthma do not take asthma-preventer medication as their asthma is recognized as mild. Still, it is well-known that in this group there are patients with frequent and severe symptoms and acute attacks of asthma, defined as uncontrolled asthma. Quality of life (QoL) is less studied in these patients. Our aim was to study patient characteristics and factors with a higher risk for uncontrolled asthma and insufficient QoL in patients with mild asthma. We studied patients with asthma diagnosis 18­75 of age in Sweden who reported asthma and no asthma preventer medication. They answered questionnaires about characteristics, knowledge of asthma, asthma symptoms, acute asthma attacks and QoL. A test for asthma symptom control, the Asthma Control Test (ACT), was answered, where 20 points or more meant good asthma symptom control. Patients were regarded as having uncontrolled asthma if they had less than 20 points and/or at least one acute asthma attack the last six months. QoL was measured by the Mini Asthma Quality of Life Questionnaire. A mean score of 6 or more meant sufficient and less than 6 insufficient QoL. Of the 298 patients, 26% had uncontrolled asthma, 40% had insufficient QoL and 20% had both. Patients with risk for both uncontrolled asthma and insufficient QoL were 60 years and over, with obesity, rhinitis and those who reported insufficient knowledge of how to handle asthma. Our results suggest that patients with mild asthma need more attention, better management and follow-ups.

The association between medical conditions and gender, well-being, psychosomatic complaints as well as school adaptability.

AIM: The aim was to assess the association between medical conditions and gender, well-being, psychosomatic complaints and school adaptability. The second aim was to determine whether self-reported medical conditions should be included in class-room questionnaires that deal with well-being and risk behaviour. METHODS: A cross-sectional class-room questionnaire was given to all 15- to 16-year-olds within a Swedish county. The questionnaire included background factors, subjective health, well-being, psychosomatic complaints, self image, drug use and also several themes from the school context. In addition, there were 13 medical conditions/problems to tick (yes or no) and an open alternative for other problems/medical conditions. RESULTS: 3108 questionnaires (response rate 84%) were analysed. The majority of the girls and the boys reported no medical conditions; however, 49% of the girls and 39% of the boys reported at least one medical condition. The medical conditions were associated with gender, well-being, psychosomatic complaints and school adaptability. The association was stronger for girls than for boys. CONCLUSION: Medical conditions among these teenagers were associated with gender, well-being, psychosomatic complaints and school adaptability, particularly for girls. Our results suggest that medical conditions could preferably be included in regular classroom questionnaires.

Comorbid Heart Disease in Patients with COPD is Associated with Increased Hospitalization and Mortality - A 15-Year Follow-Up.

Purpose: The aim of this study was to examine the association of comorbid heart disease, defined as chronic heart failure or ischemic heart disease, on all-cause and cause-specific hospitalization and mortality in patients with COPD over a period of nearly 15 years. Materials and Methods: The cohort study included patients with COPD from primary and secondary care in 2005 with data from questionnaires and medical record reviews. The Swedish Board of Health and Welfare provided hospitalization and mortality data from 2005 through 2019. Cox regression analyses, adjusted for sex, age, educational level, smoking status, BMI, exacerbations, dyspnea score and comorbid diabetes or hypertension, assessed the association of comorbid heart disease with all-cause and cause-specific time to first hospitalization and death. Linear regression analyses, adjusted for the same variables, assessed this association with hospitalization days per year for those patients that had been hospitalized. Results: Of the 1071 patients, 262 (25%) had heart disease at baseline. Cox regression analysis showed a higher risk of hospitalization for patients with heart disease for all-cause (HR (95% CI) 1.55; 1.32-1.82), cardiovascular (2.14; 1.70-2.70) and other causes (1.27; 1.06-1.52). Patients with heart disease also had an increased risk of all-cause (1.77; 1.48-2.12), cardiovascular (3.40; 2.41-4.78) and other (1.50; 1.09-2.06) mortality. Heart disease was significantly associated with more hospitalization days per year of all-cause (regression coefficient 0.37; 95% CI 0.15-0.59), cardiovascular (0.57; 0.27-0.86) and other (0.37; 0.12-0.62) causes. No significant associations were found between heart disease and respiratory causes of hospitalization and death. Conclusion: Comorbid heart disease in patients with COPD is associated with an increased risk for all-cause hospitalization and mortality, mainly due to an increase of hospitalization and death of cardiovascular and other causes, but not because of respiratory disease. This finding advocates the need of a strong clinical focus on primary and secondary prevention of cardiovascular disease in patients with COPD.

Does multimorbidity result in de-prioritisation of COPD in primary care?

The aim of this study was to describe factors associated with having COPD regularly reviewed in primary care by a nurse or physician and assess whether there was de-prioritisation for COPD in multimorbid patients. We defined de-prioritisation as not having at least one check-up by a physician during a two-year period. Among 713 COPD patients in the Swedish PRAXIS study, 473 (66%) had at least one check-up during the study period (ending in 2014). Patients with check-ups were more likely to have three or more comorbid conditions (31.9% vs. 24.6%) and exacerbations (35.1% vs. 21.7%) than those without. Compared with those without comorbidity, those with three or more diagnoses had increased relative risk ratios (and 95% CI) for consultations discussing COPD with only a physician (5.63 (2.68-11.79)), COPD-nurse only (1.67 (0.83-3.37)) or both (2.11 (1.09-4.06)). COPD patients received more frequent check-ups considering COPD if they had comorbidity or a history of exacerbations. We found no evidence of de-prioritisation for COPD in multimorbid patients.

Diagnostic spirometry in COPD is increasing, a comparison of two Swedish cohorts.

Spirometry should be used to confirm a diagnosis of chronic obstructive pulmonary disease (COPD). This test is not always performed, leading to possible misdiagnosis. We investigated whether the proportion of patients with diagnostic spirometry has increased over time as well as factors associated with omitted or incorrectly interpreted spirometry. Data from medical reviews and a questionnaire from primary and secondary care patients with a doctors' diagnosis of COPD between 2004 and 2010 were collected. Data were compared with a COPD cohort diagnosed between 2000 and 2003. Among 703 patients with a first diagnosis of COPD between 2004 and 2010, 88% had a diagnostic spirometry, compared with 59% (p < 0.001) in the previous cohort. Factors associated with not having diagnostic spirometry were current smoking (OR 2.21; 95% CI 1.36-3.60), low educational level (OR 1.81; 1.09-3.02) and management in primary care (OR 2.28; 1.02-5.14). The correct interpretation of spirometry results increased (75% vs 82%; p = 0.010). Among patients with a repeated spirometry, 94% had a persistent FEV1/FVC or FEV1/VC ratio <0.70.

Factors Associated with the Non-Exacerbator Phenotype of Chronic Obstructive Pulmonary Disease.

Background: Patients with chronic obstructive pulmonary disease (COPD) and no exacerbations may need less maintenance treatment and follow-up. The aim was to identify factors associated with a non-exacerbator COPD phenotype. Methods: Cross-sectional analysis of 1354 patients from primary and secondary care, with a doctor's diagnosis of COPD. In 2014, data on demographics, exacerbation frequency and symptoms using COPD Assessment Test (CAT) were collected using questionnaires and on spirometry and comorbid conditions by record review. The non-exacerbator phenotype was defined as having reported no exacerbations the previous six months. Multivariable logistic regression with the non-exacerbator phenotype as dependent variable was performed, including stratification and interaction analyses by sex. Results: The non-exacerbator phenotype was found in 891 (66%) patients and was independently associated with COPD stage 1 (OR [95% CI] 5.72 [3.30-9.92]), stage 2 (3.42 [2.13-5.51]) and stage 3 (2.38 [1.46-3.88]) compared with stage 4, and with CAT score <10 (3.35 [2.34-4.80]). Chronic bronchitis and underweight were inversely associated with the non-exacerbator phenotype (0.47 [0.28-0.79]) and (0.68 [0.48-0.97]), respectively. The proportion of non-exacerbators was higher among patients with no maintenance treatment or a single bronchodilator. The association of COPD stage 1 compared with stage 4 with the non-exacerbator phenotype was stronger in men (p for interaction 0.048). In women, underweight and obesity were both inversely associated with the non-exacerbator phenotype (p for interaction 0.033 and 0.046 respectively), and in men heart failure was inversely associated with the non-exacerbator phenotype (p for interaction 0.030). Conclusion: The non-exacerbator phenotype is common, especially in patients with no maintenance treatment or a single bronchodilator, and is characterized by preserved lung function, low symptom burden, and by absence of chronic bronchitis, underweight and obesity and heart failure. We suggest these patients may need less treatment and follow-up, but that management of comorbid conditions is important to avoid exacerbations.

The SELMA study: a birth cohort study in Sweden following more than 2000 mother-child pairs.

BACKGROUND: This paper describes the background, aim and study design for the Swedish SELMA study that aimed to investigate the importance of early life exposure during pregnancy and infancy to environmental factors with a major focus on endocrine disrupting chemicals for multiple chronic diseases/disorders in offspring. METHODS: The cohort was established by recruiting women in the 10th week of pregnancy. Blood and urine from the pregnant women and the child and air and dust from home environment from pregnancy and infancy period have been collected. Questionnaires were used to collect information on life styles, socio-economic status, living conditions, diet and medical history. RESULTS: Of the 8394 reported pregnant women, 6658 were invited to participate in the study. Among the invited women, 2582 (39%) agreed to participate. Of the 4076 (61%) non-participants, 2091 women were invited to a non-respondent questionnaire in order to examine possible selection bias. We found a self-selection bias in the established cohort when compared with the non-participant group, e.g. participating families did smoke less (14% vs. 19%), had more frequent asthma and allergy symptoms in the family (58% vs. 38%), as well as higher education among the mothers (51% vs. 36%) and more often lived in single-family houses (67% vs. 60%). CONCLUSIONS: These findings indicate that the participating families do not fully represent the study population and thus, the exposure in this population. However, there is no obvious reason that this selection bias will have an impact on identification of environmental risk factors.

Eczema in early childhood is strongly associated with the development of asthma and rhinitis in a prospective cohort.

BACKGROUND: This study aimed to estimate the association between eczema in early childhood and the onset of asthma and rhinitis later in life in children. METHODS: A total of 3,124 children aged 1-2 years were included in the Dampness in Building and Health (DBH) study in the year 2000, and followed up 5 years later by a parental questionnaire based on an International Study of Asthma and Allergies in Childhood protocol. The association between eczema in early childhood and the incidence of asthma and rhinitis later in life was estimated by univariable and multivariable logistic regression modelling. RESULTS: The prevalence of eczema in children aged 1-2 years was 17.6% at baseline. Children with eczema had a 3-fold increased odds of developing asthma (adjusted odds ratio [aOR], 3.07; 95% confidence interval (CI) 1.79-5.27), and a nearly 3-fold increased odds of developing rhinitis (aOR, 2.63; 1.85-3.73) at follow-up compared with children without eczema, adjusted for age, sex, parental allergic disease, parental smoking, length of breastfeeding, site of living, polyvinylchloride flooring material, and concomitant allergic disease. When eczema was divided into subgroups, moderate to severe eczema (aOR, 3.56; 1.62-7.83 and aOR, 3.87; 2.37-6.33, respectively), early onset of eczema (aOR, 3.44; 1.94-6.09 and aOR, 4.05; 2.82-5.81; respectively), and persistence of eczema (aOR, 5.16; 2.62-10.18 and aOR, 4.00; 2.53-6.22, respectively) further increased the odds of developing asthma and rhinitis. Further independent risk factors increasing the odds of developing asthma were a parental history of allergic disease (aOR, 1.83; 1.29-2.60) and a period of breast feeding shorter than 6 months (aOR, 1.57; 1.03-2.39). The incidence of rhinitis was increased for parental history of allergic disease (aOR, 2.00; 1.59-2.51) and polyvinylchloride flooring (aOR, 1.60; 1.02-2.51). CONCLUSION: Eczema in infancy is associated with development of asthma and rhinitis during the following 5-year period, and eczema is one of the strongest risk factors. Early identification is valuable for prediction of the atopic march.

Exhaled nitric oxide and urinary EPX levels in infants: a pilot study.

BACKGROUND: Objective markers of early airway inflammation in infants are not established but are of great interest in a scientific setting. Exhaled nitric oxide (FeNO) and urinary eosinophilic protein X (uEPX) are a two such interesting markers. OBJECTIVE: To investigate the feasibility of measuring FeNO and uEPX in infants and their mothers and to determine if any relations between these two variables and environmental factors can be seen in a small sample size. This was conducted as a pilot study for the ongoing Swedish Environmental Longitudinal Mother and child Asthma and allergy study (SELMA). METHODS: Consecutive infants between two and six months old and their mothers at children's health care centres were invited, and 110 mother-infant pairs participated. FeNO and uEPX were analysed in both mothers and infants. FeNO was analyzed in the mothers online by the use of the handheld Niox Mino device and in the infants offline from exhaled air sampled during tidal breathing. A 33-question multiple-choice questionnaire that dealt with symptoms of allergic disease, heredity, and housing characteristics was used. RESULTS: FeNO levels were reduced in infants with a history of upper respiratory symptoms during the previous two weeks (p < 0.002). There was a trend towards higher FeNO levels in infants with windowpane condensation in the home (p < 0.05). There was no association between uEPX in the infants and the other studied variables. CONCLUSION: The use of uEPX as a marker of early inflammation was not supported. FeNO levels in infants were associated to windowpane condensation. Measuring FeNO by the present method may be an interesting way of evaluating early airway inflammation. In a major population study, however, the method is difficult to use, for practical reasons.

Nurse-led multidisciplinary programme for patients with COPD in primary health care: a controlled trial.

AIM: To investigate the effects of a nurse-led multidisciplinary programme (NMP) of pulmonary rehabilitation in primary health care with regard to functional capacity, quality of life (QoL), and exacerbations among patients with chronic obstructive pulmonary disease (COPD). METHOD: A 1-year longitudinal study with a quasi-experimental design was undertaken in patients with COPD, 49 in the intervention group and 54 in the control group. Functional capacity was assessed using the 6-minute walking test, and quality of life (QoL) was assessed using the Clinical COPD Questionnaire. Exacerbations were calculated by examination of patient records. RESULTS: No significant differences were found between the groups in functional capacity and QoL after 1 year. The exacerbations decreased in the intervention group (n = -0.2) and increased in the control group (n = 0.3) during the year after NMP. The mean difference of change in exacerbation frequency between the groups was statistically significant after one year (p=0.009). CONCLUSIONS: The NMP in primary care produced a significant reduction in exacerbation frequency, but functional capacity and QoL were unchanged. More and larger studies are needed to evaluate potential benefits in functional capacity and QoL.

Prediction of Mortality Using Different COPD Risk Assessments - A 12-Year Follow-Up.

PURPOSE: A multidimensional approach in the risk assessment of chronic obstructive pulmonary disease (COPD) is preferable. The aim of this study is to compare the prognostic ability for mortality by different COPD assessment systems; spirometric staging, classification by GOLD 2011, GOLD 2017, the age, dyspnea, obstruction (ADO) and the dyspnea, obstruction, smoking, exacerbation (DOSE) indices. PATIENTS AND METHODS: A total of 490 patients diagnosed with COPD were recruited from primary and secondary care in central Sweden in 2005. The cohort was followed until 2017. Data for categorization using the different assessment systems were obtained through questionnaire data from 2005 and medical record reviews between 2000 and 2003. Kaplan-Meier survival analyses and Cox proportional hazard models were used to assess mortality risk. Receiver operating characteristic curves estimated areas under the curve (AUC) to evaluate each assessment systems´ ability to predict mortality. RESULTS: By the end of follow-up, 49% of the patients were deceased. The mortality rate was higher for patients categorized as stage 3-4, GOLD D in both GOLD classifications and those with a DOSE score above 4 and ADO score above 8. The ADO index was most accurate for predicting mortality, AUC 0.79 (95% CI 0.75-0.83) for all-cause mortality and 0.80 (95% CI 0.75-0.85) for respiratory mortality. The AUC values for stages 1-4, GOLD 2011, GOLD 2017 and DOSE index were 0.73, 0.66, 0.63 and 0.69, respectively, for all-cause mortality. CONCLUSION: All of the risk assessment systems predict mortality. The ADO index was in this study the best predictor and could be a helpful tool in COPD risk assessment.

Primary health care centres with asthma clinics: effects on patients knowledge and asthma control.

AIM: To evaluate outcomes for patients attending primary care centres with and without asthma clinics. METHODS: A cross-sectional survey at 42 primary health care centres randomly selected according to organisation of asthma care, 14 with complete, 14 with incomplete and 14 with no asthma clinic according to national criteria. 1,477 randomly selected patients 15-45 years received two questionnaires. Outcomes were: patients' knowledge of asthma; asthma control; and quality of life. RESULTS: Patients attending primary health care centres with asthma clinics reported more knowledge of asthma but similar levels of asthma control and quality of life. Patients who reported they had visited the asthma nurse during the last year had more knowledge but similar asthma control and quality of life compared to patients who reported they had not. However, with more time allocated for the nurse, 44% achieved asthma control compared with 27% at asthma clinics with less time (p<0.003). CONCLUSIONS: Having an asthma clinic at a primary health care centre improves asthma patients' knowledge of the disease, and better asthma control is achieved if the nurse is allocated more time.
