trials in adults with moderate (MezzoTinA-asthma®) or severe (PrimoTinA-asthma®) asthma were pooled; the other analyses were performed by trial. Since in PrimoTinA-asthma® no in-clinic measurement of pre-dose PEF was performed, correlation analyses in these pooled trials were limited to pre-dose FEV 1.

Allergic or atopic asthma (sometimes called extrinsic asthma) is due to an allergy to antigens; usually the offending allergens are suspended in the air in the form of pollen, dust, smoke, automobile exhaust, or animal dander. Peak expiratory flow (PEF) monitoring is often used to establish the relationship between occupational exposure and asthma. FEV 1 has been found to be a better physiologic index than PEF in the measurement of airflow obstruction. Conclusion: Our analysis has shown early and consistent improvements in lung function measured by AM PEF using the study enrollment criterion of ≥ 150 eosinophils/µL. We also identified a relationship between baseline blood eosinophils and improvements in AM PEF with mepolizumab in patients with severe eosinophilic asthma. Peak expiratory flow rate (PEF) or forced expiratory volume in 1 s (FEV1) monitoring is an important clinical tool to assess the degree of 24-h variation (circadian) in lung function, which correlates with the degree of airway hyperresponsiveness. Ideally, PEF measurements should be taken frequently … BAKGRUND Astma är en folksjukdom; 8-10 % av den vuxna svenska befolkningen lider av sjukdomen, som är multifaktoriell.
4 year follow up. Questionnaire. 91 %. Dust. 97 %. PEF. av följande: positivt reversibilitetstest med beta-2 stimulerare, signifikant peak flow variation, positiv bronkial provokationstest (t.ex. mannitol eller metakolin ).
Mean changes in PEF across morning/day shifts were compared between workers with occupational asthma, confirmed using specific challenge testing, and non-working asthmatics. Individuals were divided into a development set, used to identify the optimum cross-shift change for diagnosing occupational asthma, and an evaluation set, used to test the sensitivity and specificity of this value.

Asthma is a chronic (long-term) condition in which yourairways swell and become narrow. Further, it makes it difficult for you tobreathe and can make some daily activities challenging or evenimpossible. Many people find asthma to be a minor nuisance.
PEF across work and rest days that are compatible with occupational asthma. These include immediate decreases in PEF (within an hour of arriving at work or being exposed to a specific exposure at work), delayed decreases in PEF (either starting later in the working day or after leaving work), cumulative decreases in PEF over the working week 2001-12-01 Bronchial Asthma • PEF variability is greater than 20% over a 12 hour-period compared with morning values in patients taking bronhchodilators (or greater than 10% in patients not taking bronchodila-tors); or • PEF drops more than 15% after 6 minutes of running or physical exercises. 2018-06-15 2009-05-29 environmental (including occupational) causes of asthma symptoms by monitoring PEF 2-4 times each day for at least 2 weeks.

A minimal clinically important difference (MCID) in PEF has not been fully established, but in asthma clinical trials a change in AM PEF between 19 and 25 L/min from baseline is considered clinically significant [ 27 , 28 ]. These included (i) 389 serial PEF records from workers diagnosed as having occupational asthma based on independent clinical investigations of either specific bronchial challenge test [positive result defined as at least 15–20% fall in forced expiratory volume in 1 s (FEV 1) from baseline value in response to exposure to the occupational agent and no significant FEV 1 fall in response to See treating asthma and what to do if you have an asthma attack for more information. Speak to your GP or asthma nurse if you've been diagnosed with asthma and don't have a personal action plan, or if you're concerned about your peak flow score and don't know what to do. 2021-04-12 · The unreliability of PEF diaries is probably one of the main reasons why PEF monitoring does not contribute as much to the success of asthma self management as one would assume intuitively. 25 Recently, we showed that up to 50% of entries in PEF diaries of affluent white asthmatic children whom we considered to be “model patients” were either invented or falsified.
