“…The minimum morning PEF and maximum evening PEF were determined, respectively, as the lowest and highest PEF during the 1-week monitoring period [20]. The daily amplitude of PEF variation was determined according to the following formula and expressed as a percentage: amplitude5(highest PEF -lowest PEF)/highest PEF.…”

The effects of a 3-month physical training programme on airway inflammation and clinical outcomes were studied in school-aged children with asthma.Subjects with persistent allergic asthma (aged 12.7¡3.4 yrs; n534) were randomly allocated into training and control groups. Exercise consisted of twice-weekly 50-min sessions for 12 weeks. Inflammation was assessed by levels of exhaled nitric oxide, blood eosinophils, eosinophil cationic protein, C-reactive protein, and total and mite-specific immunoglobulin (Ig)E. Lung volumes and bronchial responsiveness to methacholine were determined. The Paediatric Asthma Quality of Life Questionnaire and Paediatric Asthma Caregiver's Quality of Life Questionnaire were used to evaluate activity restrictions, symptoms and emotional stress. The efficacy of the training was assessed by accelerometry.Following the programme, the exercise group spent twice as much time as the controls undertaking moderate-to-vigorous activities. No differences in changes were seen between groups for asthma outcomes. However, total IgE decreased more in the exercise group, as did mite-specific IgE.Training did not increase inflammation in children with persistent asthma, and may have decreased both total and allergen-specific immunoglobulin E levels. It is concluded that there is no reason to discourage asthmatic children with controlled disease to exercise.

“…Lung function was measured by determination of forced expiratory volume 1 s (FEV1) using the PIKO-1 Ò (Ferraris Respiratory Europe Ltd, Hertford, UK) (24). Patients were asked to perform a set of three technically acceptable manoeuvres and the highest FEV1 measurement was registered and expressed as predicted percent.…”

Background: The traditional Mediterranean diet is claimed to possess antioxidant and immune‐regulatory properties in several chronic diseases. Typical Mediterranean foods have recently been associated with improvement of symptoms of asthma and rhinitis in children. However the effect of adherence to Mediterranean diet on adult asthma outcomes is unknown. We aimed to investigate the association between adherence to Mediterranean diet and asthma control.Methods: Cross sectional study of 174 asthmatics, mean (SD) age of 40 (15) years. The patients were defined as controlled, in contrast to noncontrolled, if they showed FEV1 ≥ 80% of predicted, exhaled nitric oxide (NO) ≤35 ppb, and Asthma Control Questionnaire score <1. Dietary intake was obtained by a food frequency questionnaire, and Mediterranean diet was assessed by alternate Mediterranean Diet (aMED) Score. Logistic regression models adjusting for confounders were performed to estimate the association between Mediterranean diet and asthma control.Results: Controlled asthmatics (23%) had significantly higher aMED Score, intake of fresh fruit, and lower intake of ethanol compared to noncontrolled (77%). High adherence to Mediterranean diet reduced 78% the risk of noncontrolled asthma after adjusting for gender, age, education, inhaled corticosteroids and energy intake (OR = 0.22; 95% CI = 0.05–0.85; P‐trend = 0.028). The higher intake of fresh fruit decreased the probability of having noncontrolled asthma (OR = 0.29; 95% CI = 0.10–0.83; P‐trend = 0.015), while the higher intake of ethanol had the opposite effect (OR = 3.16; 95% CI = 1.10–9.11; P‐trend = 0.035).Conclusion: High adherence to traditional Mediterranean diet increased the likelihood of asthma to be under control in adults. The study introduces a novel link between diet and asthma control, as measured by symptoms, lung function and exhaled NO.

“…Several attempts have been made to improve early detection of airflow limitationusing new parameters and new devices [7,13,14,15,16,17,18,19,20,21,22,23,24]. Van Schayck et al [17], for example, demonstrated that it is possible to detect patients at high risk for COPD in a general practice at low costs with little effort and time by evaluating age, smoking habits and respiratory symptoms as well as by measuring forced expiratory volume in 1 s (FEV 1 ).…”

Measuring FEV<sub>6</sub> for Detecting Early Airway Obstruction in the Primary Care Setting

et al. 2009

Background: The prevalence of asthma and chronic obstructive pulmonary disease (COPD) is high (∼7.4–18%) in the general population, but less than half are diagnosed. Several studies have shown FEV₆ as a good surrogate marker for forced vital capacity (FVC) to detect airflow limitations. Objectives: The aim of this study was to evaluate if it is possible to simplify and improve the diagnosis of so far undiagnosed asthma or COPD in the primary care setting by measuring FEV₆ with a new simple screening device (PiKo-6). Methods: 507 patients were recruited from three general practices from May to June 2005. Patients with any known pulmonary disease were excluded by questionnaire. FEV₁, FEV₆ and FEV₁/FEV₆ were determined using a PiKo-6 device. Patients with an FEV₁/FEV₆ <80% (PiKo positive) were invited to a standardized pulmonary function test to confirm or rule out airflow limitation. Results: 401 (79.1%) patients showed FEV₁/FEV₆ ≥80% (PiKo negative), and 106 (20.9%) patients were PiKo positive. Of the 106 PiKo-positive patients, 74 patients (14.7% of total) agreed to further studies and 18 patients (3.6%) of them suffered from COPD [COPD 0: 5 (1.0%); COPD I: 9 (1.8%); COPD II: 4 (0.8%), and none with COPD III or IV] and 14 patients (2.8%) suffered from bronchial hyperresponsiveness or asthma. In 42 patients (8.3%), the pulmonary function test was normal. Conclusions: Measurement of FEV₆ using a new simple screening device (PiKo-6) may improve the detection rate of undiagnosed airflow limitation in the primary care setting. However, patients should be carefully selected.
