- Background: Dietary patterns defined using principal component analysis (PCA) offer an alternative to the analysis of individual foods and nutrients and have been linked with asthma and allergic disease. However, results have not been reproducible in different settings.Objective: To identify dietary patterns common to different European countries and examine their associations with asthma and allergic symptoms. Methods: In sixteen study centers in nine European countries, 3206 individuals aged 15-77 years completed a common, internationally validated, food frequency questionnaire and a respiratory symptoms questionnaire. The outcomes of interest were current asthma, asthma symptoms score (derived based on responses to 5 asthma symptom-related questions), atopy (positive skin prick test). Spirometry was used to estimate forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), the FEV1/FVC, spirometric restriction (FVC below the lower limit of normal (Results: Two dietary patterns emerged, generally correlating with the same foods in different countries: one associated with intake of animal proteins and carbohydrates; the other with fruit and vegetables. There was evidence that the former pattern was associated with a higher asthma score (RR 1.63, 95% CI: 1.33-2.01), current asthma (RR 2.03, 95% CI: 1.52-2.71), wheeze (RR 1.84, 95% CI: 1.30-2.60), atopic status (RR 1.68, 95% CI: 1.16-2.44) and with decreased lung function, including an FVC Conclusions and Clinical Relevance: Our findings suggest an increase in sensitisation to common allergens, an increase in asthma symptoms, and a reduction in lung function in those eating a diet rich in animal proteins and carbohydrates. We found little evidence of an association between these outcomes and eating a diet rich in fruits and vegetables.

- Background Anaphylaxis, which is rare, has been reported after COVID-19 vaccination, but its management is not standardized.Method Members of the European Network for Drug Allergy and the European Academy of Allergy and Clinical Immunology interested in drug allergy participated in an online questionnaire on pre-vaccination screening and management of allergic reactions to COVID-19 vaccines, and literature was analysed.Results No death due to anaphylaxis to COVID-19 vaccines has been confirmed in scientific literature. Potential allergens, polyethylene glycol (PEG), polysorbate and tromethamine are excipients. The authors propose allergy evaluation of persons with the following histories: 1-anaphylaxis to injectable drug or vaccine containing PEG or derivatives; 2-anaphylaxis to oral/topical PEG containing products; 3-recurrent anaphylaxis of unknown cause; 4-suspected or confirmed allergy to any mRNA vaccine; and 5-confirmed allergy to PEG or derivatives. We recommend a prick-to-prick skin test with the left-over solution in the suspected vaccine vial to avoid waste. Prick test panel should include PEG 4000 or 3500, PEG 2000 and polysorbate 80. The value of in vitro test is arguable.Conclusions These recommendations will lead to a better knowledge of the management and mechanisms involved in anaphylaxis to COVID-19 vaccines and enable more people with history of allergy to be vaccinated.

Tidskriftsartikel (refereegranskat)abstract
- Concerns exist that the positive association of physical activity with better lung function, which has been suggested in previous longitudinal studies in smokers, is due to reverse causation. To investigate this, we applied structural equation modeling (SEM), an exploratory approach, and marginal structural modeling (MSM), an approach from the causal inference framework that corrects for reverse causation and time-dependent confounding and estimates causal effects, on data from participants in the European Community Respiratory Health Survey (ECRHS, a multicentre European cohort study initiated in 1991-1993 with ECRHS I, and with two follow-ups: ECRHS II in 1999-2003, and ECRHS III in 2010-2014). 753 subjects who reported current smoking at ECRHS II, with repeated data on lung function at ECRHS I, II and III, physical activity at ECRHS II and III, and potential confounders at ECRHS I and II, were included in the analyses. SEM showed positive associations between physical activity and lung function in both directions. MSM suggested a protectivecausaleffect of physical activity on lung function (overall difference in mean beta (95% CI), comparing active versus non-active individuals: 58 mL (21-95) for forced expiratory volume in one second and 83 mL (36-130) for forced vital capacity). Our results suggest bi-directional causation and support a true protective effect of physical activity on lung function in smokers, after accounting for reverse causation and time-dependent confounding.

- Objective: This study investigates the prevalence and the association between restless legs syndrome (RLS) and a large variety of health variables in two well-characterized random samples from the general population in Reykjavik, Iceland, and Uppsala, Sweden. Methods: Using the national registries of inhabitants, a random sample from adults aged 40 and over living in Reykjavík, Iceland (n= 939), and Uppsala, Sweden (n= 998), were invited to participate in a study on the prevalence of COPD (response rate 81.1% and 62.2%). In addition, the participants were asked to answer the following questionnaires: International RLS Rating Scale, Short Form-12, the Epworth Sleepiness Scale, and questions about sleep, gastroeosophageal reflux, diabetes and hypertension, as well as pharmacological treatment. Interleukin-6 (IL-6), C-reactive protein (CRP) and ferritin were measured in serum. Results: RLS was more commonly reported in Reykjavik (18.3%) than in Uppsala (11.5%). Icelandic women reported RLS almost twice as often as Swedish women (24.4 vs. 13.9% p= 0.001), but there was no difference in prevalence of RLS between Icelandic and Swedish men. RLS was strongly associated with sleep disturbances and excessive daytime sleepiness. Subjects with RLS were more likely to be ex- and current smokers than subjects without RLS (p< 0.001). Respiratory symptoms and airway obstruction were more prevalent among those reporting RLS and they also estimated their physical quality of life lower than those without RLS (p< 0.001). RLS was not associated with symptoms of the metabolic syndrome like hypertension, obesity, markers of systemic inflammation (IL-6 and CRP) or cardiovascular diseases. Ferritin levels were significantly lower in RLS participants (p= 0.0002), but not (p= 0.07) after adjustment for center, age, sex and smoking history. Conclusion: Restless legs syndrome was twice as common among Icelandic women compared to Swedish women. No such difference was seen for men. RLS was strongly associated with smoking and respiratory symptoms, decreased lung function, sleep disturbances, excessive daytime sleepiness, and physical aspects of life quality. RLS was not associated with markers of the metabolic syndrome like hypertension, obesity, cardiovascular diseases or biomarkers of systemic inflammation.

- STUDY OBJECTIVES: To analyse the prevalence of sleep problems in subjects with CRS and to determine whether the disease severity of CRS affects sleep quality.METHODS: Questionnaires were sent to a random sample of 45 000 adults in four Swedish cities. Questions on CRS, asthma, allergic rhinitis, co-morbidities, tobacco use, educational level and physical activity were included. CRS was defined according to the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) epidemiological criteria. The disease severity of CRS was defined by the number of reported CRS symptoms. Sleep quality was assessed using the Basic Nordic Sleep Questionnaire.RESULTS: Of the 26 647 subjects, 2249 (8.4%) had CRS. Reported sleep problems were 50-90% more common among subjects with CRS compared with those without or the total population. The prevalence of reported sleep problems increased in conjunction with the severity of CRS. After adjusting for gender, BMI, age, tobacco use, asthma, somatic diseases, physical activity level and educational level, participants with four symptoms of CRS (compared with subjects without CRS symptoms) displayed a higher risk of snoring (adj. OR (95% CI): 3.13 (2.22-4.41)), difficulties inducing sleep (3.98 (2.94-5.40)), difficulties maintaining sleep (3.44 (2.55-4.64)), early morning awakening (4.71 (3.47-6.38)) and excessive daytime sleepiness (4.56 (3.36-6.18)). The addition of persistent allergic rhinitis to CRS further increased the risk of sleep problems.CONCLUSIONS: Sleep problems are highly prevalent among subjects with CRS. The disease severity of CRS negatively affects sleep quality.

- Study Objectives: Chronic rhinosinusitis (CRS) is a common inflammatory disease of the nasal cavity and paranasal sinuses. Associations between CRS and poor sleep quality have been reported. This 10-year follow-up study investigates possible associations between incident CRS and sleep quality. Methods: A questionnaire was sent to 16,500 individuals in Sweden, Norway, Denmark, Iceland and Estonia in 2000. It included questions on airway diseases, age, sex, body mass index, smoking habits, comorbidities, education and sleep quality. In 2010, a second questionnaire was sent to the same individuals, with a response rate of 53%. A subgroup of 5,145 individuals without nasal symptoms in 2000 was studied. Multiple logistic regression was performed to examine associations between CRS (defined according to the European position paper on rhinosinusitis and nasal polyps epidemiological criteria) at follow-up and sleep quality, with adjustment for potential confounders. Individuals with the respective sleep problem at baseline were excluded. Results: Over 10 years, 141 (2.7%) of the individuals without nasal symptoms in 2000 had developed CRS. CRS was associated with difficulties inducing sleep (adjusted odds ratio 2.81 [95% CI 1.67–4.70]), difficulties maintaining sleep (2.07 [1.35–3.18]), early morning awakening (3.03 [1.91–4.81]), insomnia (2.21 [1.46–3.35]), excessive daytime sleepiness (2.85 [1.79–4.55]), and snoring (3.31 [2.07–5.31]). Three insomnia symptoms at baseline increased the risk of CRS at follow-up by 5.00 (1.93–12.99). Conclusions: Incident CRS is associated with impaired sleep quality and excessive daytime sleepiness. Insomnia symptoms may be a risk factor for the development of CRS. © 2019 American Academy of Sleep Medicine. All rights reserved.
