Int J Chron Obstruct Pulmon Dis 2022; 17:1323-1338. [PMID: 35706707 PMCID: PMC9188979 DOI: 10.2147/copd.s364899] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2022] [Accepted: 04/30/2022] [Indexed: 11/23/2022] Open
Abstract
Background There is sparse literature on parental chronic obstructive pulmonary disease (COPD) as a risk factor for the development of COPD in adult offspring, and the impact on disease severity. We aimed to map the literature reporting on the prevalence of and/or association between parental COPD and COPD in offspring, and to evaluate whether or not the literature reports on the severity of COPD or other health-related outcomes in offspring with parental COPD. Methods A systematic literature search in Embase and Ovid MEDLINE was performed in June 2021. Search terms revolved around COPD and predisposition. Results Thirteen studies were identified: 10 case–control studies, two cross-sectional studies and one cohort study. Population size varied from 44 to 2668 offspring cases; the distribution of female cases varied from 5% to 80% and mean age ranged from 27 to 65. Nine studies used an antecedents approach and evaluated the prevalence of parental COPD in patients with COPD, which ranged from 19% to 58%. Four studies used a descendants approach, by identifying patients with COPD and subsequently evaluated prevalence of COPD in their offspring, and found a prevalence of 0% to 17%. Apart from one, all the studies found an increased odds ratio for COPD in individuals with parental COPD. Four studies reported on parental smoking history and nine studies reported on smoking history in offspring. Three studies evaluated the association between parental COPD and COPD-related outcomes in patients with COPD. Conclusion This review indicates that parental COPD is associated with a higher risk of COPD in offspring. The literature is sparse, and we identified a knowledge gap on whether parental COPD is a risk factor for severe COPD and other health conditions in offspring.

Diagnostics (Basel) 2021; 11:diagnostics11091637. [PMID: 34573977 PMCID: PMC8466239 DOI: 10.3390/diagnostics11091637] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2021] [Revised: 09/02/2021] [Accepted: 09/03/2021] [Indexed: 11/16/2022] Open
Abstract
Asthma may have an impact on lung function decline but conflicting results are reported in forced expiratory volume in one second (FEV1) decline. We aimed to describe the changes in FEV1 in lifelong non-smoking adult asthmatic outpatients during a 10-year follow-up comparing years 1–5 (1st period) with years 6–10 (2nd period) to assess factors affecting these changes. A total of 100 outpatients performed spirometry every 3 months during a 10-year survey. FEV1/Ht3 slope values of the 2nd period reduced significantly respect to the 1st period (p < 0.0001). FEV1 slopes of years 1–5 and 6–10 were inversely associated with FEV1 at enrolment (p = 0.02, p = 0.01, respectively). Reversibility and variability FEV1 showed a significant effect on the 1st period slopes (p = 0.01 and p < 0.04, respectively). Frequent exacerbators in the 1st year had steeper FEV1/Ht3 slopes in the 1st period (p = 0.01). The number of subjects using higher doses of ICS was significantly lower at the 10th years respect to the 5th and the 1st year (p < 0.001, p = 0.003, respectively). This study shows that FEV1 decline in treated adult asthmatics non-smokers, over 10-year follow-up, is not constant. In particular, it slows down over time, and is influenced by FEV1 at enrolment, reversibility, variability FEV1 and exacerbation score in the 1st year.

Abstract
Electrical impedance tomography (EIT) is a functional radiation-free imaging technique that measures regional lung ventilation distribution by calculating the impedance changes in the corresponding regions. The aim of the present review was to summarize the current literature concerning the methodologies and applications of EIT in lung diseases with flow limitation and hyperinflation. PubMed was searched up to May 2020 to identify studies investigating the use of EIT in patients with asthma, bronchiectasis, bronchitis, bronchiolitis, chronic obstructive pulmonary disease, and cystic fibrosis. The extracted data included study design, EIT methodologies, interventions, validation and comparators, population characteristics, and key findings. Of the 44 included studies, seven were related to simulation, animal experimentation, or reconstruction algorithm development with evaluation on patients; 27 studies had the primary objective of validating EIT technique and measures including regional ventilation distribution, regional EIT-spirometry parameters, end-expiratory lung impedance, and regional time constants; and 10 studies had the primary objective of applying EIT to monitor the response to therapeutic interventions, including various ventilation supports, patient repositioning, and airway suctioning. In pediatric and adult patients, EIT has been successfully validated for assessing spatial and temporal ventilation distribution, measuring changes in lung volume and flow, and studying regional respiratory mechanics. EIT has also demonstrated potential as an alternative or supplement to well-established measurement modalities (e.g., conventional pulmonary function testing) to monitor the progression of obstructive lung diseases, although the existing literature lacks prediction values as references and lacks clinical outcome evidence.

BJGP Open 2020; 4:bjgpopen20X101059. [PMID: 32753558 PMCID: PMC7606152 DOI: 10.3399/bjgpopen20x101059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2019] [Accepted: 01/06/2020] [Indexed: 10/31/2022] Open
Abstract
BACKGROUND Spirometry is essential to identify cases with obstructive lung diseases (OLDs) in primary care. However, knowledge about the long-term prognostic outcome among younger individuals is sparse. AIM To describe the predictive value of spirometry among individuals in the age groups 30-49 years and 45-64 years. DESIGN & SETTING A population-based cohort study supplied with data from Danish national registries. METHOD Spirometry was performed in 905 adults aged 30-49 years in 1991 and in 1277 adults aged 45-64 years in 2006. The participants were categorised into three groups: forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) <70, 70-75, and >75. They were followed throughout 2017 using Danish national registries. Lung disease was defined as fulfilling at least one of the following: two prescriptions for respiratory medicine were redeemed within a year; one lung-related contact to the hospital; or lung-related death. RESULTS In the 1991 cohort, 21% developed lung diseases and in the 2006 cohort 17% developed lung diseases throughout 2017. The probability of developing lung disease if FEV1/FVC 70-75 was 35% (95% confidence interval [CI] = 25% to 44%) in the 1991 cohort and 23% (95% CI = 17% to 28%) in the 2006 cohort. The positive predicted value (PPV) was higher for both cohorts when focusing on smoking history and self-reported respiratory symptoms. CONCLUSION The initial spirometry has a high predictive value to identify cases of future lung diseases. In addition, the group with FEV1/FVC 70-75 had a high risk of developing lung diseases later in life, suggesting this group would be a meaningful target of special interest.
