  • Neutrophil-to-lymphocyte ratio, blood eosinophils and COPD exacerbations: a cohort study
  • 2021
  • Ingår i: ERJ Open Research. - : ERS Publications. - 2312-0541. ; 7:4
  • Tidskriftsartikel (refereegranskat)abstract
    • Background Blood neutrophil-to-lymphocyte ratio (NLR) and blood eosinophils (B-Eos) are emerging biomarkers in COPD. This study examined whether they could predict acute exacerbations of COPD (AECOPDs), and determined their longitudinal stability.Methods In this closed cohort study, Swedish subjects with spirometry-verified COPD attended three yearly visits in a stable phase of the disease. Blood cell counts, spirometry and questionnaire-assessed AECOPD-history (worsening of COPD leading to an unscheduled visit and/or use of antibiotics and/or oral corticosteroids) were collected at each visit.Results Of 466 included subjects 57% were female. Baseline mean±sd forced expiratory volume in 1 s was 58±17% predicted. High NLR (≥3.0) was more common in subjects with previous AECOPDs than in those without (33.5% versus 20.4%, p=0.002). In two-level mixed-effects logistic regression models adjusted for confounders, NLR as a continuous variable (OR 1.20, 95% CI 1.04–1.38) and B-Eos ≥300 cells·µL−1 (OR 1.54, 95% CI 1.06–2.24) were associated with future AECOPDs. In 386 subjects with blood cell data available at all three visits, the intraclass correlation coefficient for NLR was 0.61 (95% CI 0.56–0.66) and for B-Eos 0.69 (95% CI 0.64–0.73). NLR was persistently ≥3.0 in 10.6% and B-Eos was persistently ≥300 cells·µL−1 in 15.3%.Conclusions Stable phase NLR and B-Eos were associated with future AECOPDs. NLR on its own is probably not useful to predict AECOPDs but might be included in a risk scoring index. A minority of subjects with COPD had persistently elevated stable-phase NLR or B-Eos, and the biomarkers showed fair longitudinal reliability.

  • Subjective swallowing symptoms and related risk factors in COPD
  • 2019
  • Ingår i: ERJ Open Research. - : European Respiratory Society. - 2312-0541. ; 5:3
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: This study aimed to investigate the prevalence of subjective (i.e. self-reported) swallowing symptoms in a large cohort of patients with stable chronic obstructive pulmonary disease (COPD) and to identify potential related risk factors.Methods: A total of 571 patients with COPD, investigated in a stable phase, participated in this multicentre study (335 females, 236 males; mean age: 68.6 years (sd 7.7)). Data were derived from spirometry, a questionnaire and a 30-metre walking test.Results: In total, 33% (n=186) patients reported at least some degree of swallowing problem. The most frequently reported symptom was food lodging in the throat (23%). A significant relationship was found between swallowing symptoms and dyspnoea, assessed as modified Medical Research Council (mMRC) ≥2 compared with <2 (46% versus 22%; p<0.001) and health-related quality of life, assessed as the COPD Assessment Test (CAT) ≥10 (40% versus 19%; p<0.001). Swallowing problems were also related to lower physical capacity (p=0.02) but not to lung function (p>0.28).Conclusion: Subjective swallowing symptoms seem to be a common problem in patients with stable COPD. This problem is seen in all stages of the disease, but is more common in symptomatic patients and in patients with lower physical capacity.

  • 2017 Global Initiative for Chronic Obstructive Lung Disease reclassifies half of COPD subjects to lower risk group
  • 2018
  • Ingår i: The International Journal of Chronic Obstructive Pulmonary Disease. - : DOVE MEDICAL PRESS LTD. - 1176-9106 .- 1178-2005. ; 13:`, s. 165-173
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Unlike the 2014 guidelines, the 2017 Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines have removed lung function from the risk assessment algorithm of patients with COPD. The aim of this investigation was to analyze the proportion of subjects who would change to a lower risk group when applying GOLD(2017) and determine if they exhibit different characteristics in terms of inflammation, symptoms and comorbidity compared to the subjects who would remain in a high-risk group.Subjects and methods: A total of 571 subjects with physician-diagnosed and spirometry-verified COPD were included in the present study. The data consisted of measurements of lung function, inflammatory markers, together with questionnaires that covered comorbidities, COPD symptoms and medication.Results: From group C, 53% of the subjects would be reclassified to the lower risk group A, and from group D, 47% of the subjects would be reclassified to the lower risk group B when using GOLD(2017) instead of GOLD(2014). Compared to the subjects who would remain in group D, those who would change to group B were more often men (56% vs 72%); of an older age, mean (SD), 71 (8) years vs 68 (7) years; had more primary care contact (54% vs 33%); had lower levels of blood neutrophils, geometrical mean (95% CI), 5.3 (5.0, 5.7) vs 4.6 (4.3, 4.9); reported less anxiety/depression (20% vs 34%); experienced less asthma (29% vs 46%) and had fewer symptoms according to the COPD assessment test, 16 (5) vs 21 (7). All p-values were <0.05.Conclusion: The removal of spirometry from risk assessment in GOLD(2017) would lead to the reclassification of approximately half of the subjects in the risk groups C and D to the lower risk groups A and B. There are differences in age, gender, health care contacts, inflammation, comorbidity and symptom burden among those changing from group D to group B. The effects of reclassification and changes in eventual treatment for disease control and symptom burden need further investigation.

  • Alveolar Nitric Oxide in Chronic Obstructive Pulmonary Disease-A Two-Year Follow-Up
  • 2022
  • Ingår i: Biomedicines. - : MDPI. - 2227-9059. ; 10:9
  • Tidskriftsartikel (refereegranskat)abstract
    • Chronic obstructive pulmonary disease (COPD) affects the airways and gas exchange areas. Nitric oxide (NO) production from the airways is presented as FENO50 and from the gas exchange areas as alveolar NO (CANO). We aimed to evaluate, over two years, the consistency of the CANO estimations in subjects with COPD. A total of 110 subjects (45 men) who completed the study were included from primary and secondary care settings. CANO was estimated using the two-compartment model. CANO increased slightly during the two-year follow-up (p = 0.01), but FENO50 remained unchanged (p = 0.24). Among the subjects with a low CANO (<1 ppb) at inclusion, only 2% remained at a low level. For those at a high level (>2 ppb), 29% remained so. The modified Medical Research Council dyspnoea scale (mMRC) score increased at least one point in 29% of the subjects, and those subjects also increased in CANO from 0.9 (0.5, 2.1) ppb to 1.8 (1.1, 2.3) ppb, p = 0.015. We conclude that alveolar NO increased slightly over two years, together with a small decline in lung function. The increase in CANO was found especially in those whose levels of dyspnoea increased over time.
