This retrospective study included COPD patients who attended our medical center between January and October 2018, and analyzed the outcomes of their influenza vaccination, including medical visits, hospitalization, medical expenses, and the incidence of respiratory failure. Airflow limitation was stratified according to GOLD guidelines. Overall, 543 COPD patients were enrolled, including 197, 113, 126, and 107 mild, moderate, severe, and very severe patients, respectively. Of all the participants, 238 received an influenza vaccination (43.8%), which significantly reduced hospital utilization for moderate (odds ratio [OR] 0.22, 95%CI 0.09–0.51), severe (OR 0.19, 95%CI 0.08–0.44), and very severe patients (OR 0.15, 95%CI 0.05–0.5) compared to mild patients (OR 0.51, 95%CI 0.2–1.26); reduced emergency department utilization for moderate (OR 0.33, 95%CI 0.14–0.77), severe (OR 0.22, 95%CI 0.10–0.52), and very severe patients (OR 0.30, 95%CI 0.10–0.88) compared to mild patients (OR 0.64, 95%CI 0.30–1.37); and reduced the occurrence of respiratory failure for moderate (OR 0.20, 95%CI 0.06–0.68), severe (OR 0.40, 95%CI 0.16–0.98), and very severe patients (OR 0.36, 95%CI 0.15–0.82) compared to mild patients (OR 0% CI 0.14–3.20). Influenza vaccination is more effective in COPD patients with moderate, severe, and very severe airflow obstruction than in those with mild obstruction with respect to hospital utilization, emergency department utilization, and respiratory failure.

Background: Chronic obstructive pulmonary disease (COPD) is defined as a disease state characterised by persistent respiratory symptom and airflow limitation which is not fully reversible. It has been reported that patient with COPD has higher mortality due to cardiac disorder. We have designed this study with an aim to evaluate electrocardiography and echocardiography changes in COPD patients and correlate this finding with severity of disease.Method: In present study 60 randomly selected COPD patients were evaluated clinically, echocardiographically, electrocardiographically and pulmonary function test was performed. A careful history of patient was taken regarding demography, symptoms and aggravation factors. Detailed clinical examination of patient was done to know the sign symptom of cardiological and respiratory involvement.Result: In patients with severe COPD 4 (20%) patients have normal ECG, 12 (60%) have P pulmonale, 14 (70%) patients have right ventricular hypertrophy, low voltage complex was found in 6 (30%), RBBB was present in 4 (20%) patients, 12 (60%) have r wave in their electrocardiograph (ECG) and 2 (10%) patients presented with arrhythmia.Conclusions: From our study we can conclude that most of the patients with COPD were in 5th and 6th decade of life with male predominance. Patients with moderate airflow obstruction were common than severe obstruction. Cardiovascular changes depend upon the severity of disease.

RationaleChronic obstructive pulmonary disease (COPD) comprises distinct phenotypes, all characterised by airflow limitation.ObjectivesWe hypothesised that somatotype changes – as a surrogate of adiposity – from early adulthood follow different trajectories to reach distinct phenotypes.MethodsUsing the validated Stunkard's Pictogram, 356 COPD patients chose the somatotype that best reflects their current body build and those at ages 18, 30, 40 and 50 years. An unbiased group-based trajectory modelling was used to determine somatotype trajectories. We then compared the current COPD-related clinical and phenotypic characteristics of subjects belonging to each trajectory.Measurements and main resultsAt 18 years of age, 88% of the participants described having a lean or medium somatotype (estimated body mass index (BMI) between 19 and 23 kg·m−2) while the other 12% a heavier somatotype (estimated BMI between 25 and 27 kg·m−2). From age 18 onwards, five distinct trajectories were observed. Four of them demonstrating a continuous increase in adiposity throughout adulthood with the exception of one, where the initial increase was followed by loss of adiposity after age 40. Patients with this trajectory were primarily females with low BMI and DLCO (diffusing capacity of the lung for carbon monoxide). A persistently lean trajectory was seen in 14% of the cohort. This group had significantly lower forced expiratory volume in 1 s (FEV1), DLCO, more emphysema and a worse BODE (BMI, airflow obstruction, dyspnoea and exercise capacity) score thus resembling the multiple organ loss of tissue (MOLT) phenotype.ConclusionsCOPD patients have distinct somatotype trajectories throughout adulthood. Those with the MOLT phenotype maintain a lean trajectory throughout life. Smoking subjects with this lean phenotype in early adulthood deserve particular attention as they seem to develop more severe COPD.

Abstract Background: Previous studies have shown that tuberculosis (TB) is a risk factor for chronic airflow limitation. Chronic obstructive pulmonary disease (COPD) is recognized as the result of chronic inflammation, usually related to noxious particles. Post-TB airflow obstruction and tobacco-related COPD have the same functional pathway characterized by persistent airflow limitation. We sought to compare the profile of 29 cytokines in the sputum of subjects with post-TB airflow obstruction and those with COPD related to tobacco.Results: The forced expiratory volume in the first second (FEV1) and forced expiratory volume/forced vital capacity (FEV/FVC) ratio were lower in the COPD patients with the history of smoking compared to the post-TB airflow obstruction subgroup. The stages of the disease were more advanced in COPD / tobacco patients. Among the cytokines, IL-1α, IL-1β, MIP-1β, sCD40L and VEGF levels were higher in COPD patients, compared to the controls with p values ​​of 0.003, 0.0001, 0.03, 0.0001 and 0.02 respectively. When the two COPD subgroups were compared, IL-1α, IL-6, TNF-α and IL-8 levels were higher in the COPD patients with the history of tobacco compared to the COPD patients with the history of TB with p-values ​​of 0.031, 0.05, 0.021 and 0.016, respectively. Conclusion: COPD related to tobacco is more severe than post-TB airflow obstruction. The pathogenesis of post-TB airflow obstruction appears to involve the cytokines IL-1RA, IL-1α, IL-1β, IL-17, GRO and sCD40L, while COPD related to tobacco involves more cytokines.

Abstract Background: Previous studies have shown that tuberculosis (TB) is a risk factor for chronic airflow limitation. Chronic obstructive pulmonary disease (COPD) is recognized as the result of chronic inflammation, usually related to noxious particles. Post-TB airflow obstruction (post-TB/AFO) and tobacco-related COPD (COPD/tobacco) have the same functional pathway characterized by persistent airflow limitation. We sought to compare the profile of 29 cytokines in the sputum of subjects with post-TB/AFO and those with COPD/tobacco. Results: The forced expiratory volume in the first second (FEV 1 ) and FEV1/forced vital capacity (FEV 1 /FVC) ratio were lower in the COPD/tobacco subgroup compared to the COPD/post-TB subgroup. The stages of the disease were more advanced in COPD / tobacco patients. Among the cytokines, IL-1α, IL-1β, MIP-1β, sCD40L and VEGF levels were higher in COPD patients, compared to the controls with p values ​​of 0.003, 0.0001, 0.03, 0.0001 and 0.02 respectively.

Conclusion: COPD/tobacco is more severe than post-TB/AFO. The pathogenesis of post-TB/AFO appears to involve the cytokines IL-1RA, IL-1α, IL-1β, IL-17, GRO and sCD40L, while COPD/tobacco involves more cytokines.

Background/Aim. Peripheral muscle weakness and nutritional disorders, firstly loss of body weight, are common findings in patients with chronic obstructive pulmonary disease (COPD). The aim of this study was to analyse the impact of pulmonary function parameters, nutritional status and state of peripheral skeletal muscles on exercise tolerance and development of dyspnea in COPD patients. Methods. Thirty COPD patients in stable state of disease were analyzed. Standard pulmonary function tests, including spirometry, body pletysmography, and measurements of diffusion capacity were performed. The 6-minute walking distance test (6MWD) was done in order to assess exercise tolerance. Level of dyspnea was measured with Borg scale. In all patients midthigh muscle cross-sectional area (MTCSA) was measured by computerized tomography scan. Nutritional status of patients was estimated according to body mass index (BMI). Results. Statistically significant correlations were found between parameters of pulmonary function and exercise tolerance. Level of airflow limitation and lung hyperinflation had significant impact on development of dyspnea at rest and especially after exercise. Significant positive correlation was found between MTCSA and exercise tolerance. Patients with more severe airflow limitation, lung hyperinflation and reduced diffusion capacity had significantly lower MTCSA. Conclusion. Exercise tolerance in COPD patients depends on severity of bronchoobstruction, lung hyperinflation and MTCSA. Severity of bronchoobstruction and lung hyperinflation have significant impact on dyspnea level.
