A Pooled Analysis of Mortality in Patients with COPD Receiving Dual Bronchodilation with and without Additional Inhaled Corticosteroid.

BackgroundRecent studies report a lower mortality rate during treatment with long-acting muscarinic antagonist (LAMA)/long-acting β2-agonist (LABA)/inhaled corticosteroid (ICS) versus LAMA/LABA in patients with symptomatic chronic obstructive pulmonary disease (COPD) and a history of exacerbations.ObjectiveWe compared time to all-cause mortality with LAMA/LABA versus LAMA/LABA/ICS in patients with mild-to-very-severe COPD and a predominantly low exacerbation risk.MethodsData were pooled from six randomized controlled trials (TONADO 1/2, DYNAGITO, WISDOM, UPLIFT and TIOSPIR; LAMA/LABA: n = 3156, LAMA/LABA/ICS: n = 11,891). Analysis was on-treatment and data were censored at 52 weeks. Patients on LAMA/LABA/ICS received ICS prior to study entry, which was not withdrawn at randomization. Patients on LAMA/LABA/ICS were propensity score (PS)-matched to patients on LAMA/LABA who had not previously received ICS; covariates included age, sex, geographical region, smoking status, post-bronchodilator forced expiratory volume in 1 second percent predicted, exacerbation history in previous year, body mass index and time since diagnosis. Time to all-cause mortality was assessed using Cox proportional hazard regression models.ResultsAfter PS matching, 3133 patients on LAMA/LABA and 3133 patients on LAMA/LABA/ICS were analyzed. Fewer than 20% of patients reported ≥2 exacerbations in the prior year (LAMA/LABA: 19.1%; LAMA/LABA/ICS: 19.0%). There were 41 (1.3%) deaths on LAMA/LABA and 45 (1.4%) deaths on LAMA/LABA/ICS. No statistically significant difference in time to death was observed between treatment arms (hazard ratio for LAMA/LABA 1.06; 95% confidence intervals 0.68, 1.64; P = 0.806). Sensitivity analyses conducted using different covariates or in an intent-to-treat population showed similar results.ConclusionThis pooled analysis of over 6000 patients with mild-to-very-severe COPD and predominantly low exacerbation risk showed no differences in mortality with LAMA/LABA versus LAMA/LABA/ICS, suggesting that the survival benefit of triple therapy seen in some recent studies may be specific to a high-risk population. This supports current Global Initiative for Chronic Obstructive Lung Disease recommendations that triple therapy should be reserved for the subpopulations of patients who need it the most (eg, those with an eosinophilic phenotype and a high risk of exacerbations) to avoid ICS overuse.

Assessment of Subclinical Carotid Atherosclerosis in Patients with Chronic Obstructive Pulmonary Disease

Background: Elevated coronary morbidity and mortality of patients with chronic obstructive pulmonary diseases (COPD). Common intimate-media thickening (CCA-IMT) and carotid plaques are replacement markers of atherosclerosis and predictors of CV cases. Purpose and objectives: The present research aimed at assessing and evaluating the incidence of subclinical carotid atherosclerotic vascular diseases in patients with COPD Sujets and methods: a cross-sectional sample of 75 topics has been conducted; 25 stable COPD patients and 50 controls (25 patients with other chest diseases and 25 apparently healthy persons). They were divided into three groups: Group I: 25 healthy COPD patients (Global initiative for Chronic Obstructive Lung Disease Recommendations 2020 diagnosis and gravity of COPD) (GOLD 2020). Group II: 25 people and other underlying pulmonary conditions. Group III: 25 people seemingly well. The thesis lasted between 6 and 12 months Results: The prevalence of carotid disease in COPD patients was slightly higher than controls. Multinomial analyses of logistic regression have shown COPD to be an independent carotid plague indicator. Conclusion: Subclinical atherosclerosis is greatly correlated with COPD. These results will help to prepare appropriate strategies for CV prevention.

Consistency of chronic obstructive pulmonary disease regimens for patients visiting community pharmacies with the Global Initiative for Chronic Obstructive Lung Disease recommendations

ObjectiveDespite evidence-based Global Initiative for Chronic Obstructive Lung Disease (GOLD) recommendations, outcomes are poor. GOLD uses chronic obstructive pulmonary disease (COPD) assessment test (CAT) scores with exacerbation history to categorize COPD severity into A, B, C, and D severity groups. Therapy is group-specific; monotherapy/dual long-acting bronchodilators (LABDs) therapy is preferred to inhaled corticosteroids (ICS). Pharmacist-accessible data could be used to identify evidence-based interventions to improve outcomes. The primary objective was to analyze previously collected data to compare the consistency of patient-described COPD regimens with GOLD therapeutic recommendations to identify potential pharmacist interventions. MethodsCross-sectional, nonrandomized design using a written questionnaire and CAT scores. Dispensing data from 35 Missouri community pharmacies initially identified participants aged 40 years or older with 1 or more COPD medications dispensed in the past year. Those self-reporting COPD, emphysema, or chronic bronchitis completed a demographic survey with medication history, including oral corticosteroid and antibiotic use, and CAT scores. Proportion of days covered (PDC) was calculated for any COPD maintenance medication dispensed over 1 year. The participants’ COPD was categorized into A, B, C, and D severity groups. The reported medication regimens were categorized into consistent with, escalated from, or less than initial first-line/alternative recommended therapy for the A, B, C, and D severity groups. ResultsThe participants totaled 709 (group A: 6%; group B: 35%; group C: 4%; group D: 55%). Of the regimens, 41% were consistent with, 34% were escalated from, and 24% were less than initial first-line/alternative GOLD recommendations. Most (96%) of the participants were highly symptomatic. Regimens containing ICS: (67.5%); ICS plus LABD (37.2%) exceeded dual LABD (4.2%). The average PDC was 0.43 ± 0.37; only 28.7% were adherent (PDC ≥ 0.80). ConclusionsParticipants with self-reported COPD were highly symptomatic and nonadherent; undertreatment was noted. Community pharmacists could provide therapeutic interventions consistent with GOLD A, B, C, and D severity groups, promote dual LABD versus ICS therapies, and optimize adherence.

Alignment of Inhaled Chronic Obstructive Pulmonary Disease Therapies with Published Strategies. Analysis of the Global Initiative for Chronic Obstructive Lung Disease Recommendations in SPIROMICS.

Despite awareness of chronic obstructive pulmonary disease (COPD) treatment recommendations, uptake is poor. The Subpopulations and Intermediate Outcome Measures in COPD Study (SPIROMICS) spans 2010-2016, providing an opportunity to assess integration of 2011 Global Initiative for Obstructive Lung Disease (GOLD) treatment strategies over time in a large observational cohort study. To evaluate how COPD treatment aligns with 2011 GOLD strategies and determine factors associated with failure to align with recommendations. Information on inhaled medication use collected via questionnaire annually for 4 years was compiled into therapeutic classes (long-acting antimuscarinic agent, long-acting β-agonist, inhaled corticosteroids [ICS], and combinations thereof). Medications were not modified by SPIROMICS investigators. 2011 GOLD COPD categories A, B, C, and D were assigned. Alignment of inhaler regimen with first-/second-line GOLD recommendations was determined, stratifying into recommendation aligned or nonaligned. Recommendation-nonaligned participants were further stratified into overuse and underuse categories. Of 1,721 participants with COPD, at baseline, 52% of regimens aligned with GOLD recommendations. Among participants with nonaligned regimens, 46% reported underuse, predominately owing to lack of long-acting inhalers in GOLD category D. Of the 54% reporting overuse, 95% were treated with nonindicated ICS-containing regimens. Among 431 participants with 4 years of follow-up data, recommendation alignment did not change over time. When we compared 2011 and 2017 recommendations, we found that 47% did not align with either set of recommendations, whereas 35% were in alignment with both recommendations. Among SPIROMICS participants with COPD, nearly 50% reported inhaler regimens that did not align with GOLD recommendations. Nonalignment was driven largely by overuse of ICS regimens in milder disease and lack of long-acting inhalers in severe disease.

IL-26 in the induced sputum is associated with the level of systemic inflammation, lung functions and body weight in COPD patients.

BackgroundChronic inflammatory process is the main link in COPD pathogenesis, which causes structural changes in the respiratory tract and lungs. In overweight patients, an adipose tissue could contribute to activation of the inflammatory process. Therefore, it is highly important to identify potential biomarkers of inflammation for patients with COPD and obesity. The aim of this study was to investigate the role of interleukin-26 (IL-26) and evaluate the relationship between the level of systemic inflammation, lung function, and body mass index (BMI) in patients with COPD.Patients and methodsEighty-three patients with COPD in the stable condition (stage 2 according to the 2016 Global Initiative for Chronic Obstructive Lung Disease recommendations), aged 40–70 years, were included in the study. All patients were divided into 2 groups: obese (n=53) (BMI – 30.0–39.9 kg/m2) and non-obese (n=30) (BMI – 18.5–24.9 kg/m2). We conducted patients’ examination, spirometry, induced the sputum, determined the level of C-reactive protein (CRP), leptin in serum and IL-26 in sputum.ResultsObese and non-obese COPD patients had a significant increase in IL-26 compared with healthy subjects by 2.3 and 2.6 (P=0.0003). We also observed a higher level of CRP by 1.38 times (P=0.0008), compared with the rate in non-obese COPD patients, and by 1.8 times (P=0.015) higher concentration level of leptin compared with healthy subjects. The sputum IL-26 level had positive correlation with BMI, CRP, and leptin, and a negative – with forced expiratory volume in 1 second (FEV1) and FEV1/forced vital capacity. Leptin level had positive correlation with BMI and CRP, and negative with FEV1, FEV1/forced vital capacity.ConclusionObese COPD patients had a higher level of persistent systemic inflammation than non-obese ones, which is confirmed by a significant increase of CRP and leptin in serum. The data confirm that IL-26 can be considered as a perspective marker to detect the inflammation level in lung tissue of COPD patients.

Clinical impact of nasal budesonide treatment on COPD patients with coexistent rhinitis.

BackgroundA high percentage of patients with COPD report chronic nasal symptoms. The study aims to evaluate the clinical impact of a 2-month treatment with inhaled nasal budesonide (100 µg per nostril twice daily) in patients affected by COPD with chronic rhinitis comorbidity.Patients and methodsFifty-three stable COPD patients in therapy according to the Global initiative for chronic Obstructive Lung Disease recommendations were enrolled; 49 completed the study. At enrollment (visit 0), patients underwent skin prick test and rhinoscopy. At visit 0 and after 1 month (visit 1) and 2 months (visit 2) of therapy with nasal budesonide, patients underwent spirometry, and COPD assessment test (CAT), Sinonasal Outcome Test (SNOT 22), and modified Medical Research Council dyspnea scale were administered. Differences in continuous variables, after 2 months of treatment with nasal budesonide, were evaluated using a paired t-test or Wilcoxon matched-pairs signed-ranks test.ResultsTwo months of treatment with nasal budesonide showed a significant statistical improvement in the total scores of CAT, SNOT 22, and modified Medical Research Council (p<0.001). A significant relationship between CAT and SNOT 22 total scores at baseline and after treatment was observed.ConclusionThe results of the present study indicate the importance of careful evaluation of the presence of chronic nasal symptoms in all COPD patients and suggest beneficial clinical effect from treatment with nasal budesonide in terms of COPD symptoms and quality of life.

Effect of a Primary Care Continuing Education Program on Clinical Practice of Chronic Obstructive Pulmonary Disease: Translating Theory Into Practice

ObjectivesTo describe the development and implementation process and assess the effect on self-reported clinical practice changes of a multidisciplinary, collaborative, interactive continuing medical education (CME)/continuing education (CE) program on chronic obstructive pulmonary disease (COPD). MethodsMultidisciplinary subject matter experts and education specialists used a systematic instructional design approach and collaborated with the American College of Chest Physicians and American Academy of Nurse Practitioners to develop, deliver, and reproduce a 1-day interactive COPD CME/CE program for 351 primary care clinicians in 20 US cities from September 23, 2009, through November 13, 2010. ResultsWe recorded responses to demographic, self-confidence, and knowledge/comprehension questions by using an audience response system. Before the program, 173 of 320 participants (54.1%) had never used the Global Initiative for Chronic Obstructive Lung Disease recommendations for COPD. After the program, clinician self-confidence improved in all areas measured. In addition, participant knowledge and comprehension significantly improved (mean score, 77.1%-94.7%; P<.001). We implemented the commitment-to-change strategy in courses 6 through 20. A total of 271 of 313 participants (86.6%) completed 971 commitment-to-change statements, and 132 of 271 (48.7%) completed the follow-up survey. Of the follow-up survey respondents, 92 of 132 (69.7%) reported completely implementing at least one clinical practice change, and only 8 of 132 (6.1%) reported inability to make any clinical practice change after the program. ConclusionA carefully designed, interactive, flexible, dynamic, and reproducible COPD CME/CE program tailored to clinicians' needs that involves diverse instructional strategies and media can have short-term and long-term improvements in clinician self-confidence, knowledge/comprehension, and clinical practice.
