Serial blood eosinophils and clinical characteristics in COPD patients without a history of asthma or atopy

Conclusions: The COPD patients included in this study had no specific clinical characteristics, depending on blood eosinophil count. Further larger prospective studies are needed.

AbstractBackgroundPrevious studies have suggested an increased risk of asthma related to indoor dampness problems, but their role in the etiology of Asthma-COPD Overlap Syndrome has not been studied. We utilized a population-based incident case –control study to assess potential effect of indoor dampness and molds at home and at work on development of ACOS.MethodsWe recruited systematically all new cases of asthma diagnosed during a 2.5-year study period (1997 –2000) and randomly selected controls from the source population of adults 21–63 years old and representing 500,000 persons-years in the Pirka...

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....

Conclusion: COPD patients with comorbid asthma had higher risk of exacerbations. Lower lung function and IgE-sensitization were associated to exacerbations in the one-year follow-up.

ConclusionWhile most PCPs and respiratory/allergy specialists can reach a working diagnosis of ACO, there remains uncertainty around which diagnostic features are most important and what constitutes optimal management. It is imperative that clinical studies including patients with ACO are initiated, allowing the generation of evidence ‐based management strategies.This article is protected by copyright.

Forced oscillation technique (FOT) has a potential to evaluate respiratory pathophysiology in asthma that spirometry does not detect. Since lung function decline in children with asthma has been reported to have significant impact on development of COPD in later life, we investigated changes in FOT parameters in children/adolescents with asthma in relation with changes in maximal expiratory flow at 50 % of the forced vital capacity (MEF50), an index for the small airways.

Background: Eosinophils and neutrophils play roles in asthma and COPD severity and treatment response. Cellular mediators are promising treatment targets. However, their roles in asthma and COPD phenotypes have never been investigated.Objective: To investigate eosinophilic and neutrophilic mediators in asthma with and without fixed airflow obstruction (FAO) and COPD with and without blood eosinophilia (BE).Materials and methods: Asthma, COPD patients and healthy subjects were recruited from 2016 to 2017. Spirometry and reversibility test were performed. ACT, modified MRC and CAT were assessed. Blood eosinophils, neutrophil...

Conclusions: The present results provide new insight into the role of allergy and heredity for ACOS among subjects with adult-onset asthma. Prevention of smoking and facilitating stopping smoking are important among asthmatic subjects to prevent development of the COPD component.
