Authors: Ring B, Burbank AJ, Mills K, Ivins S, Dieffenderfer J, Hernandez ML Abstract Objectives: Objective measurements of asthma impairment could aid teens in recognition of changes in asthma status over time. Ready access to a conventional spirometer is not realistic outside of the clinical setting. In this proof-of-concept study, we compared the performance of the VitalFlo mobile spirometer to the nSpire KoKo® sx1000 spirometer for accuracy in measuring Forced Expiratory Volume in one second (FEV1) and Forced Vital Capacity (FVC) in adolescents with asthma.Methods: Two hundred forty pulmonary function measu...

Conclusions: Variation in the NAT1 gene modifies asthma risk in children exposed to secondhand-smoke. To our knowledge, this is the first report of a gene-environment interaction between NAT1 variants, smoke exposure, cotinine levels, and pediatric asthma. NAT1 genotype may have clinical utility as a biomarker of increased asthma risk in children exposed to smoke. PMID: 31809667 [PubMed - as supplied by publisher]

Conclusion This study suggests that specific questions about triggers and severity of wheeze, measurement of FeNO and BPT by methacholine or exercise contribute more to the diagnosis of asthma in school-aged children than spirometry, bronchodilator reversibility and skin-prick tests.

Conclusions: Our study suggest the functional activity of IgE to SEs in severe asthmatic patients. These results can be clinically relevant in patients not sensitized to perennial allergens who can be candidates to anti-IgE therapy.

Introduction: In differential diagnosis of allergic diseases, such as asthma, chronic urticaria (CU) and Hymenoptera venom allergy (HVA), the complete blood count (CBC) and spirometry are one of the crucial examinations.Aims and Objectives: To assess the blood lymphocytes, monocytes, basophiles and neutrophils and spirometry parameters in patients with asthma, CU and HVA in comparison to healthy subjects.Methods: The study involved 48 patients with asthma, 19 with CU, 12 with HVA and 17 healthy individuals. Participants had a spirometry and CBC examinations performed.Results: The absolute values of neutrophils were highest...

Aim: Examination of patients (pts) with two broncho-obstructive diseases (A and COPD) requires addressing the issue: is it originally A or COPD? We looked at the problem from COPD.Material and Methods: We studied 38 smokers with COPD II-III stages (age–61.4±3.8 yrs, pack/year–28.8±4.3) repeatedly (3-8 yrs) in stable phase on adequate therapy. Measurements included clinical status, spirometry with bronchoobstructive reversibility test (BORT) and allergic markers: blood eosinophil level (E), common IgE level (cIgE) in plasma, Phadiatop (Ph) in serum. Each patient underwent from 3 to 9 (6.2±1....

Aspergillus (ASP) sensitization is frequent in severe asthma (SA). Aspergillus-associated disease, such as allergic bronchopulmonary aspergillosis (ABPA) and chronic pulmonary aspergillosis (CPA) can be associated with bronchiectasis (B). B is a comorbidity in patients with SA. We investigated the prevalence and the characteristics of Aspergillus-associated bronchiectasis in 73 consecutive immunocompetent patients with SA.Methods: All the patients underwent assessment of history, spirometry, FENO, circulating eosinophils (EOS), serum total IgE, IgE-ASP (increased if> 0.10 kUA/L), and IgG-ASP (increased if>40 U/ml), c...

Conclusions: Despite guideline recommendations, PFT to diagnose and manage asthma remains low from 2000-2016 in Ontario. Although there are decreasing trends in hospitalizations and ED visits, it is important to promote the use of PFT to objectively diagnose and manage asthma in order to further reduce acute care and improve the health status of people with asthma.

The association between asthma and obesity has been obeserved in many studies but the underlying mechanisms are poorly understood. Aim of the work is to evaluate the respiratory function (forced spirometry, residual volume [RV], DLCO, oscillometry [IOS] and serum concentration of IL-10, IL1-β, TGF-β1, TNF-α, IL-33, adiponectin, leptin in 28 obese non asthmatic children (O+NA) (20 M, median age: 11,7 yrs), compared with 28 obese asthmatic (O+A) and 28 non-obese asthmatic (NO+A), overlapped for sex and age, The results are the following:O+NAMedian (1-3 quartile)O+ANO+AO+NA vs O+AO+NA vs NO+Ap valueO+A vs NO+A...
