What are the Barriers of Chronic Obstructive Pulmonary Disease (COPD) Patients in Smoking Cessation?

Objectives: Smoking is the major determinant of developing chronic obstructive pulmonary disease (COPD). A substantial proportion of patients with COPD continue smoking although they have significant respiratory symptoms, exacerbation history and comorbidities. We aimed to find the associated factors and clinical features of the patients who maintain smoking. Methods: 200 current smokers and 132 former smokers with a spirometry-confirmed diagnosis of COPD were recruited from the outpatient department. Demographic characteristics, smoking backgrounds, treatment status, comorbidities, exacerbation history of the previous year, pulmonary function tests, blood biochemistry, dyspnea scales, symptom scores, and BECK anxiety scores were all recorded. Results: No age and gender differences were found between current and former smokers. Compared to former smokers, current smokers were less qualified, had more cardiovascular diseases, more frequently exposed to tobacco smoke at home and at work place, more severe pulmonary function impairment, longer duration of COPD, longer time of smoking, earlier age of commencement in smoking, higher scores of BECK anxiety scores (BAI), higher levels of inflammatory markers in blood tests p<0.05. In multivariable analysis, lower values of FEV1%, higher scores of CAT and BAI, higher levels of platelet and CRP were found to decrease the likelihood of smoking cessation p<0.05. Additionally having diabetes, coronary artery disease and hypertension were inversely correlated with quitting smoking p<0.05. Conclusion: COPD is a systemic inflammatory disease. We found over half of the patients with COPD were currently smoking, despite the severity of their airflow limitation, symptoms and even the comorbidities. Furthermore, 2 out of 5 of the current smokers reported having moderate to severe anxiety. Dyspnea and inflammatory markers had negative effects on smoking cessation, and anxiety might be the cause that led these patients to keep smoking.

Relationship Between Platelet Parameters and Eosinophils with Disease Severity, CRP and Treatment in Stable COPD.

Objectives: Chronic obstructive pulmonary disease (COPD) is a complex inflammatory condition that primarily impairs respiration but can also affect hemostasis. This study aimed to determine differences in platelet-related parameters and eosinophil between COPD patients and healthy controls. Methods: We included 149 patients with stable COPD and 30 healthy controls who were recruited from the outpatient department of Chest Diseases. Complete blood count, including platelet count (Plt), and C-reactive protein were measured. Other platelet-related parameters were determined, including mean platelet volume (MPV), platelet distribution width (PDW), plateletcrit (Pct), their ratios (MPV/Plt, MPV/Pct, PDW/Plt, PDW/Pct), and platelet to lymphocyte ratio (PLR). Results: COPD patients and controls did not show significant differences in platelet parameters (Plt, Pct, PDW, MPV, PDW/Pct, MPV/Pct). PLR was significantly higher in the patient groups than in the control group (p=0.009). Correlation between platelet count and PLR (p=0.047; p=0.05) showed borderline significance. However, we found no correlation between the patients' CRP levels, Pct, PDW, PDW/Pct, MPV/Pct and MPV values. There were no significant differences in platelet parameters in patients using and not using long-acting muscarinic antagonists (LAMA). We did not find differences in eosinophil levels among COPD severity grades. Conclusion: In our study, we found that PLR is elevated in COPD. PLR could be a useful and easily accessible parameter to evaluate ongoing inflammation in stable COPD. Large-scale studies are warranted to further investigate the role of platelet and eosinophil parameters in COPD.

Pulmonary functions and life quality assessment results two years after COVID-19 comparison with the sixth month results.

INTRODUCTION: We aimed to investigate the effects of COVID-19 on patients 24 months after severe COVID-19 pneumonia. METHODOLOGY: Fifty-four patients with severe COVID-19 pneumonia were evaluated on the 24th month after discharge from the hospital. Spirometry and short form of health-related quality of life scale (SF-36) were used. Chest computed tomography (chest-CT) was performed and the findings were grouped according to lung involvement. RESULTS: Forced expiratory volume in 1 second (FEV1) % values of 19 patients (35.18%) and forced vital capacity (FVC) % values of 23 patients (42.54%) were found lower than expected on the 24th month. Physical function, energy-vitality, social functionality and general health parameters were found lower than normal on the SF-36 scale. 27 (50.00%) patients had a chest-CT abnormality. There was a correlation between FEV1% and FVC% values and group 3: medium-lower lobe dominant, reticulation + traction, 10-50% surface area. Chest-CT of 6 patients was fully recovered. No correlation was found between chest-CT findings on the 24th month and BMI, length of hospitalization, white blood cell (WBC), lymphocyte, C-reactive protein (CRP), ferritin and D-dimer values at the time of hospitalization. CONCLUSIONS: Functional and radiological abnormalities were detected in a significant number of patients on the 24th month. A systematic monitoring plan must be established to assess and properly manage the long-term problems that may arise.

Comparison of chest computed tomography findings of RT-PCR negative and RT-PCR positive cases in COVID-19 patients.

OBJECTIVE: The purpose was to compare the results of the RT-PCR test, with the findings of Chest CT and to determine the features of CT for the diagnosis of COVID-19 and how to approach RT-PCR negative patients. MATERIAL METHOD: Chest CT findings of 569 COVID-19 diagnosed patients, followed up at the pandemic wards between March and June 2020 were retrospectively examined. Patients were grouped according to RT-PCR results, gender, and age. RESULTS: 284 (49%) were RT-PCR(+), 285 (50.8%) were RT-PCR(-) of total 569 patients. 11 (1.9%) of RT-PCR(+) had no involvement in Chest CT while all the RT-PCR(-) patients were CT(+). The distribution of lesions in CT were; 544 (95.6%) bilateral, 553 (97.2%) multilobar, 557(98%) peripherally 151 (26.5%) posteriorly localized. The most common findings were; 539 (94.7%) ground-glass opacity (GGO), 365 (64.1%) consolidation, 160 (28.1%) crazy paving interlobular septal thickening. CO-RADS mean value was 5.4 ± 0.7. GGO and reticulation in RT-PCR(-) patients were 280 (98.2%) and 24 (8.4%); while they were 259 (91.2%) and 12 (4.2%) in RT-PCR(+) patients, were significantly higher (p < 0.05). No significant difference was observed, in CT findings for gender. Only the findings of crazy paving interlobular septal thickening and reticulation in 18-64 age group were significantly higher than that in 65-94 age group, 105 (24.8%)-55 (37.9%), 19 (4.5%)-17 (11.7%) respectively (p < 0.05). CONCLUSION: The typical findings of COVID-19 pneumonia in Chest CT are: GGO, consolidation and crazy paving in bilateral, peripheral, posterior localization. CT plays an essential role for diagnosis, isolation and treatment in cases of COVID-19 and RT-PCR negative test should be verified by CT.

Evaluation of long-term radiological findings, pulmonary functions, and health-related quality of life in survivors of severe COVID-19.

OBJECTIVE: It was aimed to evaluate long-term radiological changes in severe coronavirus disease 2019 (COVID-19) patients, to investigate pulmonary function, exercise capacities, and health-related quality of life results. METHODS: Sixty-five patients with severe COVID-19 pneumonia were evaluated in the sixth month after discharge from the hospital. Spirometry, 6 min walking test (6MWT), and short form of health-related quality of life scale (SF-36) were applied in the sixth month. Chest computed tomography (CT) was performed and the findings were grouped according to lung involvement. RESULTS: Forty-nine male and 16 female patients were included in the study. Forced expiratory volume in 1 s (FEV1)% values of 18 patients (30.5%), forced vital capacity (FVC)% values of 27 patients (45.8%), and 6MWT of 13 patients (23.2%) were found lower than expected in the sixth month. On the SF-36 scale, physical function, energy-vitality, social functionality, pain, and general health parameters were found lower than normal. Minimal interstitial changes in chest CT were seen in 26 patients. Nine patients had lung area involvement between 10% and 50% of the surface, there was a correlation between FEV1% and FVC% values in this group. There was severe pulmonary fibrosis in four patients. There was a correlation between pulmonary function and physical function and general perception of health from SF-36 scale subparameters. CONCLUSION: Functional and radiological abnormalities were detected in a significant number of patients in the sixth month after severe COVID-19 pneumonia. A systematic monitoring plan must be established to assess and properly manage the long-term problems that may arise.
