RESUMO
NTRODUCTION: Obstructive sleep apnea (OSA) has a significant effect on the development of cardiovascular complications. The aim of this study was to evaluate the relationship between carotid intima-media thickness (IMT), paraoxonase 1 (PON 1) enzyme levels and severity of OSA. MATERIAL AND METHODS: A total of 120 cases were included in the study with 30 cases in each group, as follows: Group 1 (AHI 30/h). Blood samples of the patients were taken to measure serum PON1 activity. Carotid IMT of all patients included in the study was measured by means of echocardiography using vascular probe and results were recorded. RESULTS: With regard to carotid IMT, a statistically significant increase was detected as severity of OSA increased (p < 0.001). A positive relationship was detected between IMT level and total oxygen desaturation time, oxygen desaturation index and SpO2 time < 90 % (p < 0.01). When the groups were compared, a statistically significant decline was observed in serum PON 1 level as severity of OSA increased (p < 0.05). CONCLUSIONS: The findings of our study indicate that PON1 and carotid IMT might be used as indicators of vascular damage in patients with OSA. Depending on the severity of OSA, measurement of PON1 enzyme activity in conjunction with carotid IMT may help us in predicting the cardiovascular risk in patients with OSA (Tab. 4, Fig. 2, Ref. 27).

Background and aim Sarcoidosis is a multisystem inflammatory disease of unknown aetiology. This study aimed to evaluate the relationship between systemic inflammatory parameters, the systemic immune-inflammation index (SII) and the lymphocyte-to-monocyte ratio (LMR), and disease stage, clinical findings, and 18F-fluoro-2-deoxy-D-glucose (18F-FDG) tomography/computed tomography (PET/CT) uptake. Materials and methods Our study included 73 patients. The general characteristics, radiological features, spirometric tests, PET/CT findings, and laboratory parameters of the patients were recorded. Results Relapse and parenchymal fibrosis were not associated with metabolic parameters, such as LMR and SII. Serum angiotensin-converting enzyme (ACE) levels were lower in the relapsed group than in the non-relapse group. However, the patients' PET/CT images indicated that 18F-FDG parenchym maximum standard uptake value (SUV max), lymph node SUV max, lymph node short axis dimension, SII, and LMR were similar between all patients, relapsed or not. Conclusion Although found to be significant in other inflammatory diseases, we found that SII and LMR alone did not indicate disease prognosis in sarcoidosis due to the small number of patients and the lack of homogeneity between the groups in our study. The usefulness of these markers for clinical use should be investigated by studies that include those with extrapulmonary sarcoidosis, and that calculate these markers at the time of disease diagnosis and during the post-treatment period.
RESUMO
BACKGROUND AND AIM: Vaccinations have been one of the main approaches to reducing mortality and exacerbations caused by infectious agents in chronic obstructive pulmonary disease (COPD). Among viral pathogens, coronaviruses have been described to play a role. This study aims to investigate the role of coronavirus disease 2019 (COVID-19) vaccination on exacerbation reduction in patients with COPD. METHODS: Patients diagnosed with COPD prior to the study date were considered the study population. Exacerbations of COPD before and after the COVID-19 vaccination were recorded. Patients with influenza and/or pneumococcal vaccination were excluded from the study due to their known role in reducing exacerbations of COPD. RESULTS: The study included 152 patients with a mean age of 67.5 ± 9.7 years. Most patients were classified under Global Initiative for Chronic Obstructive Lung Disease (GOLD) stages 2 and 3. In fully vaccinated patients, COPD exacerbation was observed to be higher than in those without full vaccination (70.5% vs. 55.3%, respectively). Total risk status and vaccination status, however, were seen to be in a positive correlation, with higher risk and complete vaccination status presenting with a higher count of COPD exacerbation. CONCLUSION: Although it is known that the administration of COVID-19 vaccines in patients in risk groups reduces the risk of disease, there is no study showing a positive effect on COPD exacerbations alone. In our study, it was observed that only the COVID-19 vaccine was ineffective in attacks without influenza and pneumococcal vaccines.
RESUMO
Background The men infected with COVID-19 have been shown to have more severe disease and a higher mortality rate. Morbidity and mortality associated with COVID-19 are mediated through intense viral inflammation and increased levels of inflammatory biomarkers. We aimed to retrospectively evaluate any gender difference in patients with severe COVID-19 pneumonia in terms of inflammatory biomarkers. Methods Our study included 132 patients. The general characteristics, radiological features and laboratory parameters of the patients were recorded. Results No difference was observed between the genders according to comorbidities, pulse steroid requirement and hypoxemia. There was no difference between the male and female participants in terms of age, white blood cell count, lymphocyte count, red cell distribution width, C-reactive protein, troponin, albumin and D-dimer. However, duration of hospitalization; percentage of polymorphonuclear leukocyte (PNL); and haemoglobin, alanine aminotransferase and ferritin values were higher in the males, and lymphocyte percentage and platelet count were higher in the women participants. Conclusion Larger studies with gender-specific reporting and robust analyses are required to clarify how gender alters the cellular and molecular pathways associated with COVID-19. This would improve the interpretation of biomarkers and the clinical management of COVID-19 patients by facilitating a personalised medical approach to risk stratification, prevention and treatment.
RESUMO
AIM: The aim of our research was to investigate retrospectively the relationship between the symptoms and general characteristics, initial laboratory values and treatments in patients who had COVID-19 and who applied to the chest diseases outpatient clinic for control after 1 month. METHOD: Three hundred fifteen patients who were diagnosed with COVID-19 and applied to the chest diseases outpatient clinic between May 2020 and August 2020 for control in the 1st month were included in the study. Patient information was collected from the hospital information system and the e-pulse system. RESULTS: Females accounted for 50.2% of our patients and their mean age was 47.9 ± 14.8 (19-88) years. About 14.3% (n: 45) of the individuals were 65 years of age and older, 20.6% (n: 65) of our patients were smoking and 70.2% (n: 221) of our patients were treated at home. A total of 133 patients had at least one comorbid disease. The patients most frequently reported cough, dyspnoea, weakness, myalgia and diarrhoea. The most common symptoms were cough, dyspnoea, weakness and myalgia in the 1st month. Initial D-dimer, initial CRP and the values of platelet, D dimer and CRP in the 1st month were detected to be higher in patients with persistent symptoms when the laboratory values of patients whose symptoms continue after 1 month were examined. It was determined that the symptoms had persisted in patients who had been hospitalised, had dual therapy, had comorbid diseases and had more common pathologies in their pulmonary imaging. CONCLUSION: Symptoms may persist for a long time in hospitalised patients, in patients with COVID-19-related pneumonia and concomitant chronic diseases and in patients with high D-dimer and high CRP at the time of admission. Patients are informed that their symptoms may last for a long time, unnecessary hospital admissions can be avoided.

INTRODUCTION: Sjögren syndrome (SS) is a chronic, systemic, inflammatory disease characterised with lymphocytic infiltration of the exocrine glands, frequently manifested by dryness in the region affected. Although the most common extraglandular involvement in SS is pulmonary involvement. Early diagnosis and treatment is considered to be important. It was aimed to evaluate the frequency of early lung involvement, high resolution computed tomography (HRCT) findings and data of pulmonary function test (PFT) in SS in this study. MATERIALS AND METHODS: Thirty-five patients diagnosed with SS and referred by the Department of Rheumatology to determine potential lung involvement to the eighth chest diseases outpatient clinic of our hospital between September 2015 and December 2018 were included in this study. Respiratory signs, demographic features, length of disease and treatment regimens, PFT, data of 6-minute walk test and findings of HRCT of the patients were retrospectively obtained from hospital information system and patient files. RESULTS: The mean age of the patients was 54.4 ± 9.2. The majority of the patients were women (94.3%). When the HRCT findings were evaluated, 28 (80%) patients had CT findings, while 7 (20%) patients had no CT findings. The most common HRCT findings found in patients were peribronchial thickening (48.6%), ground glass appearance (28.6%) and prominence in interstitial scars. CONCLUSION: We think that the evaluation of HRCT and PFTs in patients diagnosed with SS for assessing early pulmonary involvement will be guiding in terms of follow-up and treatment.

INTRODUCTION: Our study aimed to evaluate the relationship between pneumonia, air pollution (sulfur dioxide [SO2] and particulate matter [PM10]) and meteorological data (atmospheric pressure, amount of rainfall, temperature, rate of humidity, sunshine duration and wind velocity). MATERIALS AND METHODS: Our study included 822 of the 826 patients who were admitted to the emergency service of our hospital between August 2016 and July 2017 and who were diagnosed with pneumonia. Four patients whose information was not available were excluded from the study. The data for the patients were obtained retrospectively from the hospital information system and patient emergency files. The meteorological data were obtained from the website of the Ministry of the Environment and Urbanization and from the Directorate General of Meteorology of our city. Daily meteorological data (SO2, PM10, air pressure, temperature, humidity, wind speed and sunshine duration) were compared with the number of daily patients admitted to the emergency department and diagnosed with pneumonia. Statistical analysis was performed using Pearson correlation analysis. RESULT: Three hundred and twenty-nine of the patients were female, and 493 were male. A total of 605 inpatients, of whom 106 were in the intensive care unit, were treated in the hospital, while 217 were outpatients. A statistically significant relationship was found between the number of patients with pneumonia and the intensity of SO2 (r= 0.740; p<0.001), atmospheric pressure (r= -0.691; p<0.01), wind velocity (r= 0.777; p<0.001), average humidity rate (r= -0.454; p<005) and sunshine duration (r= 0.475; p<0.05). CONCLUSIONS: We determined that meteorological changes are important risk factors in the development of pneumonia and that reducing air pollution and taking protective measures may decrease the frequency of pneumonia and the mortality rates related to pneumonia.

OBJECTIVE: Differential diagnosis of idiopathic pulmonary fibrosis (IPF) is important among fibrotic interstitial lung diseases (ILD). This study aimed to evaluate the rate of IPF in patients with fibrotic ILD and to determine the clinical-laboratory features of patients with and without IPF that would provide the differential diagnosis of IPF. MATERIAL AND METHODS: The study included the patients with the usual interstitial pneumonia (UIP) pattern or possible UIP pattern on thorax high-resolution computed tomography, and/or UIP pattern, probable UIP or possible UIP pattern at lung biopsy according to the 2011 ATS/ERS/JRS/ALAT guidelines. Demographics and clinical and radiological data of the patients were recorded. All data recorded by researchers was evaluated by radiology and the clinical decision board. RESULTS: A total of 336 patients (253 men, 83 women, age 65.8±9.0 years) were evaluated. Of the patients with sufficient data for diagnosis (n=300), the diagnosis was IPF in 121 (40.3%), unclassified idiopathic interstitial pneumonia in 50 (16.7%), combined pulmonary fibrosis and emphysema (CPFE) in 40 (13.3%), and lung involvement of connective tissue disease (CTD) in 16 (5.3%). When 29 patients with definite IPF features were added to the patients with CPFE, the total number of IPF patients reached 150 (50%). Rate of male sex (p<0.001), smoking history (p<0.001), and the presence of clubbing (p=0.001) were significantly high in patients with IPF. None of the women <50 years and none of the men <50 years of age without a smoking history were diagnosed with IPF. Presence of at least 1 of the symptoms suggestive of CTD, erythrocyte sedimentation rate (ESR), and antinuclear antibody (FANA) positivity rates were significantly higher in the non-IPF group (p<0.001, p=0.029, p=0.009, respectively). CONCLUSION: The rate of IPF among patients with fibrotic ILD was 50%. In the differential diagnosis of IPF, sex, smoking habits, and the presence of clubbing are important. The presence of symptoms related to CTD, ESR elevation, and FANA positivity reduce the likelihood of IPF.
RESUMO
Pneumococcal infections are an important cause of mortality and morbidity in Chronic Lung Diseases. However, exacerbations, which make the treatment of diseases very difficult, and corticosteroids used during treatment carry a great risk of pneumococcal infection and adversely affect the treatment. The most rational way to reduce the negative impact of pneumococcal infections on the clinical and economic burden of Chronic Lung Diseases is vaccination of the risky population. Although, vaccination recommendations are well defined, recommended by national and international guidelines and are paid by health authorities, in Turkey, vaccination rates in adults with chronic lung disease is far below the expected. Since physicians are considered to be the most important and reliable resource that can guide their patients in vaccination, applying pneumococcal vaccination routinely in all patients with chronic lung diagnosis and making it a part of daily practice will greatly contribute to reducing the clinical and economic burden of pneumococcal infections in these patients. In this review, the effects of pneumococcal diseases on chronic lung diseases, the risk and clinical burden of pneumococcal diseases in chronic lung diseases are discussed in the light of guidelines and current literature, and the importance of protection from pneumonia in these patients is emphasized. In addition to general information and efficacy data about pneumococcal vaccines available in our country, application methods and access routes to vaccines are also described.

OBJECTIVES: Coincidance of idiopathic pulmonary fibrosis (IPF) and the obstructive sleep apnea syndrome (OSA) may have important effects on the pathogenesis of each other. Our aim is to define clinical characteristics of patients with IPF and OSA and to identify a combined index to determine the severity of both diseases together. MATERIALS AND METHODS: The clinical and polysomnographic characteristics of 22 patients with OSA and IPF who underwent nocturnal polysomnography (NPSG) were retrospectively evaluated and compared with 23 OSA patients without any other pulmonary comorbidities. RESULTS: We demonstrated high frequency of OSA within our study group (94,7%) all of whom had at least one of the majör symptoms of OSA. Lower AHI, lower neck circumference, higher percentage of deep sleep (nREM3) and less comorbidities were observed in the study group when compared to OSA with no other pulmonary comorbidities (p<0,05). When restaged into a compound index according to the gender, age and physiology (GAP) index, the patients with mild IPF and OSA showed the same life and sleep quality with the patients who have higher GAP index. CONCLUSION: All patients with IPF must be questioned for the major symptoms of sleep related breathing disorders (SRBD). Clinical suspicion for OSA must prompt NPSG. With the presence of moderate-severe OSA, the life and sleep quality of patients with mild IPF can be at the same level of patients with severe IPF.
RESUMO
Lymphoepithelioma-like carcinoma (LELC), is a rare type of cancer and typically occurs in pharyngeal and foregut-derivative organs, Including the salivary glands, thymus, stomach and liver (1). Pulmonary LELC typically affects the young and non-smoking population, and is associated with Ebstein-Barr virus (EBV) infection (1,2). We present an rare case with a pulmonary mass on CT scan of the thorax, which was subsequently proved as a LELC of the lung and a brief review of the relevant literature. The patient is a 51-year old man, presented with shorthness of breath and cough for 1 months. Chest x-ray was normal (Figure 1). Chest CT scan showed a 30-25 mm heterogeneously enhanced mass lesion with well defined margin, In the left lower lobe of the lung (Figure 2). Bronchoscopy showed no endobronchial lesion. After the PET-CT, the patient was staged as cT2aN1M0 (Stage 2B) (Figure 3). He received video-assisted thoracoscopic surgery of left lower lobe of lung and mediastinal lymph nodes dissection (Figure 4,5). His Ebv-Dna is Positive in blood tests. The pathology, immunohistochemical staining,and in situ hybridization results confirmed LELC of lung (Figure 6). Using in situ hybridization with exhibition of abundant EBV-encoded small nuclear RNA, in the majority of tumor cells is done. He received 4 cycles of induction chemotherapy with cysplatine and vinoralbine. The patient was discharged from hospital with close follow-up. No recurrence has been detected so far. Primary pulmonary LELC is a rare malignant tumor which accounts for only 0.9% of all primary lung cancer (1,2). Previous studies have demonstrated that pulmonary LELC is strongly associated with EBV infection (1,2). The majority of pulmonary LELC patients receive complete resection, as well as chemotherapy and radiotherapy based on their clinical stage (1,2). Comparing to other non-small cell cancer (NSCLC), pulmonary LELC is more sensitive to chemotherapy and radiotherapy (1,2). LELC of lung may be mistaken histopathologically for metastatic nasopharyngeal carcinoma or lymphoma. Its association with latent EBV infection have major implications for diagnosis and treatment. We present this case, because, its an unusual case with a pulmonary mass of the thorax, which was proved as a LELC of the lung.

INTRODUCTION: Respiratory and cardiac functions in association with skeletal and neurophysiologic systems can be evaluated with cardiopulmonary exercise testing (CPET). Compared to treadmill exercise test, CPET provides more comprehensive data about the hemodynamic response to exercise. MATERIALS AND METHODS: We aimed to evaluate the relationship with CPET findings and coronary lesions identified on angiography in patients with angina pectoris who underwent teradmill exercise, CPET and coronary angiography (CAG). By this way we sought to examine the CPET parameters that might be predictive for coronary artery disease (CAD) before diagnostic exercise test results and ischemia symptoms develop. Thirty patients in whom CAG was planned because of symptoms and exercise test results were enrolled in the study. Oxygen consumption (VO2), carbondioxide production (VCO2), minute ventilation (VE), maximum work rate (WR), DVO2/DWR and O2 pulse (VO2/HR) values were calculated. Significant CAD was defined as ≥ 50% narrowing in at least one of the coronary arteries. RESULT: The mean age was 60.4 ± 8.9 years ve 21 (65.6%) of subjects were male. On CAG, CAD was detected in 19 (59.4%) patients. Maximum heart rate, heart rate reserve (HRR), VE/VCO2 measured at anaerobic threshold (AT) and VO2(mL/kg/min) were significantly differed in patients with CAD than those without (p= 0.031; p= 0.041; p= 0.028; p= 0.03 respectively). Peak VO2, VO2/WR and O2 pulse values were higher in patients with normal angiographic results than those with CAD but the difference did not reach to statistical significance. CONCLUSIONS: The findings of our study indicate that among CPET parameters AT VE/VCO2, ATVO2 (mL/kg/dk) and HRR can have predictive value in the diagnosis of CAD. We think that these parameters might be used in the evaluation of patients with angina and dyspnea suspected of CAD. In conclusion parameters obtained during the test that are not influenced by patient's effort might increase the value of CPET in the diagnosis CAD.

INTRODUCTION: Sleep quality is known to be associated with the distressing symptoms of cancer. The purpose of this study was to analyze the impact of cancer symptoms on insomnia and the prevalence of sleep-related problems reported by the patients with lung cancer in Turkey. MATERIALS AND METHODS: Assesment of Palliative Care in Lung Cancer in Turkey (ASPECT) study, a prospective multicenter study conducted in Turkey with the participation of 26 centers and included all patients with lung cancer, was re-evaluated in terms of sleep problems, insomnia and possible association with the cancer symptoms. Demographic characteristics of patients and information about disease were recorded for each patient by physicians via face-to-face interviews, and using hospital records. Patients who have difficulty initiating or maintaining sleep (DIMS) is associated with daytime sleepiness/fatigue were diagnosed as having insomnia. Daytime sleepiness, fatigue and lung cancer symptoms were recorded and graded using the Edmonton Symptom Assessment Scale. RESULT: Among 1245 cases, 48.4% reported DIMS, 60.8% reported daytime sleepiness and 82.1% reported fatigue. The prevalence of insomnia was 44.7%. Female gender, patients with stage 3-4 disease, patients with metastases, with comorbidities, and with weight loss > 5 kg had higher rates of insomnia. Also, patients with insomnia had significantly higher rates of pain, nausea, dyspnea, and anxiety. Multivariate logistic regression analysis showed that patients with moderate to severe pain and dyspnea and severe anxiety had 2-3 times higher rates of insomnia. CONCLUSIONS: In conclusion, our results showed a clear association between sleep disturbances and cancer symptoms. Because of that, adequate symptom control is essential to maintain sleep quality in patients with lung cancer.

Haemogram assessment is a cheap and easy method which can be readily performed for almost all patients. Leucocyte, neutrophil and lymphocyte counts and the neutrophil to lymphocyte ratio (NLR) are markers of systemic inflammation. We here aimed to evaluate haemogram parameters of our patients with lung cancer according to the pathologic diagnosis of small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC). Materials and Methods: The study included 386 patients diagnosed with lung cancer in our hospital between January 2006 and January 2014. A retrospective examination was made of the data from the patient records and the hospital information. NLR values were categorised into two groups: <3 and ≥3. Results: Median survival time in patients aged <65 years was 28.7 months and in those aged ≥65 years, it was 18.4 months (p<0.001). The median survival time was 20.2 months in NSCLC and 13.0 months in SCLC patients (p<0.001). In NSCLC cases with NLR<3 the median survival time (31.1 months) was longer than that of patients with NLR≥3 (18 months) (p=0.003). In SCLC patients, no relationship could be found between NLR and median survival time (p=0.408). With every 1 unit increase in lymphocyte count a 5.5% decrease in risk of periodic death ((1/0.947)x100=5.5%) was noted. Conclusion: The results of this study demonstrated that lymphocyte count, neutrophil count, Hb, Htc, and NLR are useful in determining prognosis in lung cancer (LC) patients and NLR could be more significant in determining the prognosis in NSCLC than in SCLC cases.
RESUMO
INTRODUCTION: Organizing pneumonia (OP) is an uncommon clinic opathological situation among lung diseases. If no underlying cause can be detected, it is named as cryptogenic OP (COP). In this study, the etiologic and clinical characteristics of patients diagnosed as OP in our hospital in the last ten years were evaluated retrospectively. It was also aimed to make a comparison between COP and secondary OP patients. MATERIALS AND METHODS: One hundred sixty-five patients diagnosed as OP pathologically in the 10 year period from August 2003 to August 2013 were included into that study. Patients' data were evaluated retrospectively from the medical records. RESULT: One hundred sixty five patients pathologically diagnosed as OP were included. Diagnostic methods were trans-thoracic fine-needle biopsy (TTFNB) in 89 (53.9%) patients, open lung biopsy (lobectomy, wedge resection, segmentectomy) in 52 (31.5%) patients and transbronchial biyopsy (TBB) in 24 (14.5%) patients. One hundred (60.6%) of the patients were defined as COP and 65 (39.4%) as secondary OP. Cough, fatigue and dyspnea were the most common symptoms on admission. We detected OP cases secondary to anthracosis and cyst hydatic besides other well known etiologies. In 61 patients, the main radiologic manifestation was multiple bilateral patchy consolidation typical for OP. In 76 patients focal lesions (solid mass, cavitating mass lesion) and in 6 patients infiltrative opacities were detected radiologically. CONCLUSIONS: There is no difference between properties of OP from clinical, laboratory and radiologic finding sin the criptogenic and seconder form of OP. Although it is not asserted, cyst hidatic and anthracosis could be kept in mind for the list of underlying ethiologies for secondary OP.

Paraneoplastic secretion of beta human chorionic gonadotropin (ß-HCG) in non-small cell lung cancer (NSCLC) has been rarely reported. A 43-year old male patient was admitted with dyspnea and chest pain. Thorax computed tomography (CT) revealed bilateral multiple masses and pleural effusion at right hemithorax. Positron emission tomography (PET)-CT showed pathologic 18 FDG uptake at mass lesions and mediastinal lymph nodes. The serum ß-HCG level was elevated. A bronchoscopy was performed and endobronchial lesion was observed. Since a definitive diagnosis was not achieved by pathologic examination of biopsy specimen, bronchoscopy was repeated and a sample was taken by cryobiopsy. The pathologic examination revealed non-small cell lung cancer.In conclusion, the case was presented because of extremely rare occurence of NSCLC secreting ß-HCG.
