RESUMO
Background: Direct oral anticoagulants (DOACs) have been used in acute pulmonary thromboembolism as an alternative to warfarin due to drug interactions, narrow therapeutic range, and necessary close International Normalized Ratio (INR) monitoring. Phase 3 study results have reported that these drugs are at least as effective as warfarin and beneficial in terms of bleeding; however, studies that present up-to-date life data are necessary. Aims: To evaluate the frequency of using DOACs, which are prescribed with a limited number of indications in our country, and real-life data results. Study Design: Cross-sectional study. Methods: This cross-sectional survey collected the clinical data (history, current treatment, treatment duration, etc.) of patients with pulmonary thromboembolism and who applied to the physician for follow-up between October 15, 2019, and March 15, 2020. The researchers kept the patient records sequentially. Results: Data from 836 patients with acute pulmonary thromboembolism from 25 centers were collected, and DOAC was used in 320 (38.5%) of them. The most preferred DOAC was rivaroxaban (n = 294, 91.9%). DOAC was mostly preferred because it could not provide an effective INR level with warfarin (n=133, 41.6%). Bleeding was observed in 13 (4%) patients. Conclusion: The use of direct oral anticoagulants is becoming almost as widespread as conventional therapy. Real-life data results are important for their contribution to clinical practice.

Background/aim: New treatment regimens for COVID-19, which has threatened the world recently, continue to be investigated. Although some of the treatments are promising, it is thought to be early to state that there is definitive treatment. Experiences and treatment protocol studies from treatment centers are still important. The aim of this study is to evaluate factors affecting the treatment process of the first cases followed in our clinic. Materials and methods: The consecutive hospitalized patients with COVID-19 pneumonia were analyzed in this retrospective and cross-sectional study. Data were recorded from the electronic and written files of patients. Results: Eighty-three patients were evaluated. The median age was 50 ± 15 years. Forty-eight (57.8%) patients had one or more comorbidities. The most common comorbidity was hypertension. The most common symptom was cough in 58 patients (70%). The overall mortality was 15%, and 85% of the patients were discharged. The time between the onset of symptoms and hospitalization was statistically significantly longer in deceased patients (P = 0.039). Age, D-Dimer, troponin, CK, CK-MB, ferritin, procalcitonin, and neutrophil to lymphocyte ratio were statistically significantly higher in deceased patients than survivor patients. In subgroup analysis, in the patients receiving azithromycin plus hydroxychloroquine and other antibiotics plus hydroxychloroquine, the duration of hospitalization was shorter in the azithromycin group (P = 0.027). Conclusion: Early treatment and early admission to the hospital can be crucial for the better treatment process. Combination therapy with azithromycin may be preferred in the first treatment choice because it can shorten the length of hospital stay.

Background: Inhaled antibiotics for treating bronchiectasis have been investigated in the cystic fibrosis population since 1981 and long-term clinical benefits have been reported. However, studies on noncystic fibrosis bronchiectasis (NCFB) have only been performed more recently. Owing to limited evidence, inhaled antibiotics are not currently approved for treating NCFB by the U.S. Food and Drug Administration and the European Medicines Agency. The aim of this study was to evaluate the efficacy and safety of tobramycin inhalation therapy in patients with bronchiectasis with Pseudomonas aeruginosa (PA) colonization. Methods: In this retrospective cross-sectional study, NCFB patients who were Pseudomonas positive on three consecutive cultures 1 month apart and receiving tobramycin inhalation therapy were evaluated. Evaluation of the following parameters was done in this study: age, gender, smoking history, symptoms, pulmonary function test results, sputum culture results, tobramycin treatment duration, side effects of tobramycin and response evaluation, and hospital admissions before and after treatment. Treatment with 300 mg tobramycin through nebulizer twice daily for 28 days on-off cycles for a total of 6 months was considered to be one treatment period. The approvals for the study were received by the local ethics committee and institutional review board. Results: Of the 27 patients, 21 patients completed the first period, 7 patients completed the second period, 4 patients completed the third period, and 1 patient completed the fourth period. Sputum culture was negative in 10 (47.6%) of the 21 patients who completed the first period. Decreased sputum purulence and quantity, dyspnea, and cough were observed during treatment. The frequency of hospitalizations before treatment was 1.24 ± 1.36, whereas after treatment, it decreased to 0.52 ± 0.91, this difference was statistically significant (p = 0.019). The most common side effect was increased dyspnea after nebulization in five patients. Conclusion: Tobramycin inhalation appears to be a well-tolerated treatment in patients with PA colonization with bronchiectasis. This treatment may decrease the hospitalization rates and improve the symptoms.

INTRODUCTION: The lung volume reduction coil treatment is a minimally invasive bronchoscopic treatment option for emphysema patients who suffer from severe hyperinflation. Previous studies have reported successful outcomes in selected cases using coil for bronchoscopic lung volume reduction (BLVR). Our aim is to determine the changes in respiratory function tests, perception of dyspnea and exercise capacities after 12 months in patients treated with endobronchial coil. MATERIALS AND METHODS: The data of patients with severe emphysema and treated with coils between 2014-2017 were evaluated retrospectively. Dynamic and static lung volume capacities at baseline and 12 months, modified Medical Research Council (mMRC) questionnaire and six-minute walk test (6-MWT) results were recorded. RESULT: BLVR was performed in thirty patients (one female, twenty-nine males). Five patients were treated bilaterally and twentyfive unilaterally. One patient died after 7 days and 4 patients died during follow-up. Five patients were lost to follow-up. A total of twenty patients with available data were included in the study. A statistically significant difference was found in mMRC results in pre-treatment and 12-month evaluations. There was no significant difference in FEV1, TLC and RV values at the end of 12 months. There was an increase of 18.9 meters (± 83.5 m) between the baseline and 12 months in 6-MWT. 45% of the patients improved their walking distance over 26 meters which is known as minimal clinically important difference (MCID). CONCLUSIONS: Although no significant changes were observed in pulmonary function tests and lung volumes, the increase in exercise capacity and decreased perception of dyspnea indicate the efficacy of endobronchial coil.

INTRODUCTION: The Severe Acute Respiratory Syndrome (SARS-CoV-2) virus, which emerged from China and spread all over the world, has affected the world in every aspect and will do so in the foreseeable future. This study was carried out to investigate the possible aggravating effect of smoking on the prognosis of patients with COVID-19 pneumonia presenting with pulmonary involvement. MATERIALS AND METHODS: 114 adult patients who received inpatient treatment in our clinic with the diagnosis of COVID-19 pneumonia between 11 March 2020 and 30 April 2020 were retrospectively included in the study; in particular, they were evaluated in terms of smoking history, severity of disease, need for NIMV and ICU admission, and mortality during their hospitalization. RESULT: The mean age of the 114 patients hospitalized with COVID-19 pneumonia was 51.14 ± 14.97 (range 16-81), and 77 (67.5%) were male. Of the patients, 19 (15.9%) were active smokers, 23 were ex-smokers (20.1%), 72 (63.1%) non-smokers. The effect of smoking on the severity of the disease, length of hospitalization, need for non-invasive mechanical ventilation (NIMV) and intensive care unit (ICU) admission and mortality were not statistically significant. CONCLUSIONS: The rate of active smoking in patients hospitalized with COVID- 19 is lower than the population average. In this study, no correlation was observed between smoking status and the severity, prognosis and mortality of the disease. Further studies with larger number of patients and case series are needed to better elucidate the relationship between smoking and COVID-19 and the pathophysiologic mechanisms of the effects of smoking on the natural history of COVID-19 pneumonia.

Aim Emphysema is a lung disease in which alveolar capillary units are destroyed supporting tissue lost. Bronchoscopic lung volume reduction (BLVR) is a novel treatment for emphysema. Several comorbidities have been reported to coexist in patients with chronic obstructive pulmonary disease (COPD). The aim of this study was to evaluate comorbidities of patients with severe emphysema who underwent BLVR and association of these comorbidities with mortality. Methods Between January 2011 and December 2017 the records of severe emphysema patients who underwent endobronchial valve (EBV) or lung volume reduction coil (LVRC) placement were reviewed retrospectively. Results There were 37 patients who received EBV therapy and 29 received LVRC therapy. There were no significant differences in the demographic and clinical characteristics between two groups before the treatment. There were seven deaths (10.6%) over the period of twelve months following the BLVR treatment. All deaths occurred in patients with at least one comorbid condition. Mortality was increased in the presence of comorbidities (14.3% vs 0%, respectively; p=0.099), and it was significantly increased in the presence of multiple comorbidities (18.5% vs 0%; p=0.059). The mortality rate was higher (37.5% vs 10.5%) in the LVRC comparing to the EBV treatment group in the presence of multiple comorbid conditions, albeit not reaching statistical significance (p=0.099). Conclusion The presence of more than one comorbidity in patients who underwent the LVRC treatment are associated with significant increase of mortality. For patients with severe emphysema who have more than one comorbidity, EBV is a better choice than LVRC.

INTRODUCTION: Pulmonary Langerhans Cell Histiocytosis (PLCH) is a rare disease affecting young smokers. It is more common between the ages of 20-40 and equals the male/female ratio. Lung biopsy is the most useful methods for diagnosis. The first treatment is to quit smoking. Corticosteroids or chemotherapeutic agents can be used in severe progressive cases despite of quiting smoking. The patients with PLCH followed in our clinic were assessed with general clinical features in the light of the literature. MATERIALS AND METHODS: We retrospectively evaluated patients with PLCH in our clinic between January 1999 and June 2017. RESULT: The female and male distribution of the 21 patients was 11/10. The average age was 35.04 ± 11.78 years. All patients were active smokers at the time of admission. The most common symptom was dyspnea. The most common finding in the pulmonary function tests was obstructive ventilatory defect. The DLCO value of the 70% patient in the carbonmonooxid diffusion test was below 80%. The most common pathologic findings detected in high-resolution chest tomography (HRCT) were cystic lesions involving bilateral upper and middle areas. There were 3 (14%) patients with pneumothorax at the time of admission and 6 (28.5%) patients with pneumothorax history before. The most common diagnostic method was open lung biopsy. All the patients quit cigarette after the diagnosis. There were 6 patients using steroid therapy, 1 patient receiving steroid and bosentan therapy, and 1 patient made pleurectomy due to recurrent pneumothorax. Lung transplantation was done to patient who received combined bosentan treatment with steroids. CONCLUSIONS: PLCH is a rare disease and should be considered in young, smokers with spontaneous pneumothorax and cystic lung disease in the differential diagnosis. As more diffusions are affected in patients, respiratory functions for follow-up should be evaluated with diffusion tests. It is essential to quit smoking in therapy.

INTRODUCTION: We have used Oki stents for a number of different indications. After discovering that there are limited reports in the literature on these stents, we were motivated to share our experiences in Oki stenting. OBJECTIVES: While there is vast knowledge on double Y-stents, the Oki stent is a relatively recent development in pulmonology. Here, we demonstrate that stenting of the right secondary carina using an Oki stent should be considered for obstructions in this region. METHODS: We placed 13 mm × 10 mm × 9 mm Oki stents in six patients under general anesthesia via rigid bronchoscopy. RESULTS: Three cases were post-transplant patients with malacia, stenosis, and bronchopleural fistula. One case had an airway obstruction due to malignant disease, another case had a right aortic arc and aberrant left subclavian artery anomaly, and the final case had bronchopleural fistula. No serious complications were observed during stent placement. CONCLUSIONS: Oki stents can safely be used for many clinical conditions. Patients benefit greatly from stenting; however, two of our cases died due to infection, and one case died due to malignancy.

BACKGROUND: Several studies have shown that obstructive sleep apnea increases incidence of cardiovascular morbidity and mortality. The high systemic oxidative stress in obstructive sleep apnea has been considered as a major pathogenic mechanism leading to cardiovascular disease. Oxidative stress-related lipid and DNA oxidation in obstructive sleep apnea have been reported in the previous studies. In contrast, there is limited and contradictory information regarding protein oxidation in obstructive sleep apnea patients such as ischaemia-modified albumin and advanced oxidation protein products. Therefore, we aimed to investigate plasma ischaemia-modified albumin and advanced oxidation protein products and their correlation with total oxidative status and total antioxidative capacity in the obstructive sleep apnea patients. METHODS: Plasma ischaemia-modified albumin, advanced oxidation protein products, total oxidative status and total antioxidative capacity were measured in 25 healthy volunteers and 59 obstructive sleep apnea patients diagnosed with polysomnography. RESULTS: Plasma total antioxidative capacity was significantly lower (P = 0·012) and total oxidative status was significantly higher (P < 0·001) in the patients compared to the controls demonstrating increased oxidative stress in the patients. Plasma advanced oxidation protein products were significantly higher in the patients than the controls (P = 0·024). Plasma ischaemia-modified albumin levels were not statistically different between the obstructive sleep apnea patients and controls (P = 0·74). CONCLUSIONS: We conclude that high systemic oxidative stress in obstructive sleep apnea is reflected by increased advanced oxidation protein products without causing an increase in ischaemia-modified albumin.

Degree of increase in pulmonary artery pressure (PAP) and adaptive responses in right ventricular morphology and mechanics play an important role in the prognosis of chronic obstructive pulmonary disease (COPD) patients. Three dimensional echocardiography and deformation imaging are recent advancements in echocardiography that allow more through assessment of right ventricle. We aimed to investigate right ventricular geometry and mechanics in a stable COPD population living at moderately high altitude. A total of 26 stable COPD patients with variable disease severity were included to this study. Pulmonary function tests, six minutes walking test (6MWT) and two- and three-dimensional echocardiography were performed for evaluation and data collection. Both systolic (43.06 ± 11.79 mmHg) and mean (33.38 ± 9.75 mmHg) PAPs were significantly higher in COPD patients compared to controls (p < 0.05, p < 0.001; respectively). Right ventricular volumes were similar between groups, although right ventricular free wall thickness was significantly increased in COPD group. The number of subjects with a sub-normal (<40 %) right ventricular ejection fraction was significantly higher in COPD group (45.8 vs. 17.4 %, p < 0.05), and the mean right ventricular strain was significantly lower (-21.05 ± 3.80 vs. -24.14 ± 5.37; p < 0.05). Only mean PAP and body surface area were found as independent predictors for 6MWT distance. Increased PAP and reduced right ventricular contractility were found in COPD patients living at moderately high altitude, although right ventricular volumes were normal. Similar findings can be expected in other COPD patients with high PAP, since these findings probably represents the effect of increased PAP on right ventricular mechanics.

INTRODUCTION: Pulmonary vasculature is affected in patients with chronic pulmonary obstructive disease (COPD). As a result of increased pulmonary resistance, right ventricular morphology and function are altered in COPD patients. High altitude and related hypoxia causes pulmonary vasoconstriction, thereby affecting the right ventricle. We aimed to investigate the combined effects of COPD and altitude-related chronic hypoxia on right ventricular morphology and function. MATERIALS AND METHODS: Forty COPD patients living at high altitude (1768 m) and 41 COPD patients living at sea level were enrolled in the study. All participants were diagnosed as COPD by a pulmonary diseases specialist depending on symptoms, radiologic findings and pulmonary function test results. Detailed two-dimensional echocardiography was performed by a cardiologist at both study locations. RESULTS: Oxygen saturation and mean pulmonary artery pressure were higher in the high altitude group. Right ventricular end diastolic diameter, end systolic diameter, height and end systolic area were significantly higher in the high altitude group compared to the sea level group. Parameters of systolic function, including tricuspid annular systolic excursion, systolic velocity of tricuspid annulus and right ventricular isovolumic acceleration were similar between groups, while fractional area change was significantly higher in the sea level groups compared to the high altitude group. Indices of diastolic function and myocardial performance index were similar between groups. CONCLUSION: An increase in mean pulmonary artery pressure and right ventricular dimensions are observed in COPD patients living at high altitude. Despite this increase, systolic and diastolic functions of the right ventricle, as well as global right ventricular performance are similar in COPD patients living at high altitude and sea level. Altitude-related adaptation to chronic hypoxia could explain these findings.
