COPD patients with asthma, characteristics and risk of exacerbations

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.

Authors: Kim SR, Park KH, Son NH, Moon J, Park HJ, Kim K, Park JW, Lee JH Abstract PURPOSE: It is difficult to assess airway obstruction using spirometry in adult asthmatic patients with preserved lung function. Impulse oscillometry (IOS) can detect not only airway resistance but also reactance. Therefore, IOS may be useful in assessing pulmonary function in such patients. We investigated the applicability of IOS for asthma patients with preserved lung function. METHODS: Between 2015 and 2018, 1,248 adult asthmatic patients suspected of having asthma who visited the Allergy and Asthma Center of Severance Hospit...

Conclusion 20% of randomly selected individuals who report respiratory symptoms in Canada have undiagnosed airflow obstruction due to asthma or COPD. Questionnaires could exclude subjects at low risk but lack the ability to accurately find subjects with undiagnosed disease.

The forced oscillation technique (FOT) is used to measure respiratory system resistance and reactance and provides information that cannot be obtained by spirometry. Recent studies indicate that the annual change in FOT correlates with change in FEV1 in patients with asthma and COPD. However, it is not fully understood in patients with ACO. The aim of this study was to investigate the relationship between the annual change in FOT and that in FEV1 in patients with asthma, COPD and ACO.

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....

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

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.
