RESUMO
Background: Asthma and chronic obstructive pulmonary disease (COPD) are the most common obstructive diseases. Based on the similarities, we aimed to evaluate sinonasal symptoms in patients with asthma or COPD, and compare the two diseases with regard to upper-airway involvement. Methods: Patients with asthma or with COPD who were followed up at Ankara University Immunology and Allergy or Chest Diseases Departments were included in the study. The participants went through pulmonary function tests, skin-prick tests, and disease severity assessment of either disease. Nasal endoscopic evaluations of all the patients were performed in the Department of Otorhinolaryngology. Lund-Mackay scoring was performed on the computed tomography of the paranasal sinus. Chronic rinosinusitis (CRS) diagnosis was made as recent guidelines. Results: A total of 112 subjects (number of women/men: n = 67/45; median age, 49 years [The range for IQR was 22 years]) were included in the study. Fifty-five patients had asthma, 33 had COPD, and 24 were healthy controls. Nasal symptoms were more frequent in the patients with asthma (patients with asthma, n = 52 [98%]; patients with COPD, n = 17 [52%]; controls, n = 9 [38%]) (p < 0.001). The median (IQR) 22-item Sino-Nasal Outcome Test (SNOT-22) questionnaire score was higher in the patients with asthma (33 [20-50]) than in the patients with COPD (8 [1.5-18.7]) and the control group (3.5 [0-18.7]) (p < 0.01). Patients with asthma had significantly higher prevalence rates of rhinosinusitis than did those in the COPD and the control groups (36%, 15.6%, 8.3%, respectively; p < 0.01). The SNOT-22 optimal cutoff score was calculated as ≥11 to detect the score limit for CRS prediction with the best sensitivity and specificity. Conclusion: As a result, patients with both asthma and COPD may have upper-airway symptoms. CRS, was primarily seen in the patients with asthma. Accordingly, SNOT-22 scores were higher in the patients with asthma than in those in the COPD and the control groups. A referral to the Ear Nose Throat department for further evaluation with nasal endoscopy and computed tomography of the paranasal may be required in a subgroup of patients.

It is important to make the differential diagnosis of restrictive changes associated with hepatic hydrothorax or hepatopulmonary syndrome seen in the later stages of chronic liver diseases and restrictive changes associated with interstitial lung disease. Lymphocytic interstitial pneumonia (LIP) is in the rare idiopathic interstitial pneumonia subgroup of interstitial lung diseases. LIP is a rare disease, and its incidence is unknown. LIP is characterized by infiltration of the alveolar interstitium with lymphocytes, plasma cells, and histiocytes. The etiology of LIP includes idiopathic causes, rheumatological diseases, immune deficiencies, viral infections, and drug-related causes. Chronic liver diseases are also rarely included in the etiology of LIP. A 75-year-old male patient who was followed up for liver cirrhosis presented with dyspnea. He had hypoxemia in the arterial blood gas. In the thorax and abdominal computed tomography, irregular reticulations in bilateral lungs, ground-glass opacities, and scattered air cysts in both lung parenchyma, chronic liver parenchymal disease, splenomegaly, chronic portal vein thrombosis were determined. Clinical and radiological changes in the patient were evaluated in favor of interstitial lung disease. Although histopathological diagnosis could not be made, the patient whose radiological pattern was compatible with LIP was evaluated together with clinical findings and was accepted as lymphocytic interstitial pneumonia. He was evaluated in terms of diseases that could cause LIP. He was accepted as LIP due to chronic liver disease. Although histopathological examination is the gold standard for the diagnosis, a biopsy could not be performed in our case. Radiological and clinical findings were considered sufficient for the diagnosis of LIP. Chronic viral hepatitis and cirrhosis are also present in the etiology of LIP. Our case is presented as an example in the literature because it is a case of LIP due to chronic liver disease, and it is rare.

INTRODUCTION: The goals of chronic obstructive pulmonary disease (COPD) treatment are to relieve dyspnea, increase exercise capacity, and improve quality of life. The relation of exercise capacity, dyspnea level, and quality of life with long-term mortality is unclear. Aim of the study was to assess the effect of exercise capacity, dyspnea level and quality of life on long-term mortality risk in patients with COPD. MATERIALS AND METHODS: Dyspnea level was assessed using the modified Medical Research Council (mMRC), Borg and Baseline Dyspnea Index (BDI) and Body Obstruction Dyspnea Exercise (BODE), health-related quality of life with St. George's Respiratory Questionnaire, and exercise capacity with the 6-minute walking test (6MWT) and cardiopulmonary exercise test. At the end of 8-year follow-up period, the relation between these tests and mortality was examined. RESULT: A total of 42 patients with stable COPD were included in the study. Sixteen patients died during the approximately 8-year follow-up period. Univariate analysis revealed that VO2 peak [HR: 1.845; CI: (1.336-2.55); p<0.001], BODE index [HR: 0.787; CI: (0.703-0.880); p<0.001], and SGRQ [HR: 1.073; CI: (1.028-1.119); p= 0.001] were significantly correlated to mortality risk. Multivariate Cox regression analysis revealed VO2 peak [HR: 1.031; CI: (0.683-1.120); p= 0.01] as the single significant predictor of mortality. VO2 peak less than 22.5 had a sensitivity of 82%, specificity of 80%, and area under the curve of 0.142 [95% CI: (0.027-0.257); p< 0.001] for mortality risk with ROC analysis. CONCLUSIONS: Cardiopulmonary disturbances during maximal exercise may be an important indicator of mortality risk.

The application quality of pulmonary function tests (PFT) carries high importance since it affects the quality of health services. "Chronic Diseases and Risk Factors in Turkey Study," which was published in 2013 showed that only 22.6% of PFTs performed in the secondary care institutions in our country were compatible with the standards. This finding reveals the standardization problem in spirometry applications in our country. Currently, the criteria for the application and evaluation of spirometer measurements were defined by American and European Respiratory Societies standards. Several laboratories use these standards in our country as in the world. But, national laboratory standards that are suitable for the conditions in our country have not been defined yet. This report was prepared to ensure the application of spirometry in optimal conditions, to minimize intra-laboratory and inter-laboratory differences and mistakes, and to standardize in our country. In this report, we focused on the standards concerning laboratory conditions, equipment, and technician specifications, test application, evaluation of test quality, infection control, and reference values.

Chronic obstructive pulmonary disease (COPD) is a complex disease that is associated with devastating outcomes resulting from lung involvement and several comorbidities. Comorbidities could impact on symptomology, quality of life, the complications, the management, economic burden and the mortality of the disease. The importance of comorbidities originates from their impact on the outcome of COPD. The most frequent comorbidities in COPD are cardiovascular, endocrinological, musculoskeletal, phycological disorders and lung cancer. Almost 50% of the COPD patients have 3 or more comorbidities. The recent Global Initiative of Obstructive Lung Disease (GOLD) Guideline suggested proactive search and the treatment of the comorbidities. However, there is no certain evidence demonstrating that active treatment of comorbidities improve the outcomes of COPD. However, it is well known that several comorbidities such as cardiovascular disease and lung cancer have greater impact on mortality caused by COPD. Several studies have shown that Charlson Comorbidity index or more recenty COPD Specific Comorbidity Index (COTE) has been found to be related with mortality of COPD. This concise review intended to summarize the most frequent comorbidities in association with their impact on COPD.

INTRODUCTION: This study aimed to determine the relationship of 6 minute walking test (6MWT) and cardiopulmonary exercise test (CPET) with each other and with the measures of lung functions in patients with chronic obstructive pulmonary disease (COPD). MATERIALS AND METHODS: Pulmonary function tests, 6MWT, and CPET were performed in 36 (35 males, 1 female) patients with moderate and severe COPD. RESULTS: Maximum oxygen uptake was significantly correlated with 6 minute walking distance. Both exercise tests were correlated with pulmonary function tests. However, maximum exercise capacity was more closely correlated with measures of lung function than 6MWT. Both tests were significantly correlated with static lung volumes. Inspiratory capacity (IC) was significantly correlated with 6MWT and CPET parameters. CPET was significantly correlated with diffusion capacity and maximal inspiratory pressure. Airway conductance and resistance tests showed no correlation with the exercise tests. CONCLUSION: 6MWT is a simple and valuable test to determine the exercise capacity of COPD patients. Both 6MWT and CPET are correlated with ventilatory impairment determined by the lung function tests, particularly FEV1, maximum voluntary ventilation (MVV), and IC. However, CPET is an exercise test that more accurately evaluates and provides more detailed information about hyperinflation and respiratory musce strength than 6MWT does.

Introduction: Patients with asthma-chronic obstructive pulmonary disease (COPD) overlap (ACO) have a greater disease burden than those with COPD or asthma alone. In this study, it was aimed to determine the prevalence, risk factors, and clinical features of ACO because there are limited national data in Türkiye. Materials and Methods: The study was conducted in a cross-sectional design in nine tertiary-care hospitals. The patients followed with a diagnosis of asthma or COPD for at least one year were enrolled in the study. The frequency of ACO and the characteristics of the patients were evaluated in the asthma and COPD groups. Result: The study included 408 subjects (F/M= 205/203, mean age= 56.24 ± 11.85 years). The overall prevalence of ACO in both groups was 20.8% (n= 85). The frequency was higher in the COPD group than in the asthma group (n= 55; 33.3% vs. n= 22; 9.8%), respectively (p= 0.001). Patients with ACO had similarities to patients with COPD in terms of advanced age, sex, smoking, exposure to biomass during childhood, being born in rural areas, and radiologic features. Characteristics such as a history of childhood asthma and allergic rhinitis, presence of chronic sinusitis, NSAID hypersensitivity, atopy, and high eosinophil counts were similar to those of patients with asthma (p<0.001). The annual decline in FEV1 was more prominent in the ACO group (mean= -250 mL) than in the asthma (mean change= -60 mL) and COPD (mean change= -230 mL) groups (p= 0.003). Conclusions: This study showed that ACO was common among patients with asthma and COPD in tertiary care clinics in our country. ACO should be considered in patients with asthma and COPD who exhibit the abovementioned symptoms.

The social patterns of smoking have changed significantly in the past two decades but smoking is still as prevalent in the lowest socioeconomic groups as it was widespread. For the solution of this enormous problem many kinds of treatment modalities have been proposed but there is no single successful method for quitting. To determine the smoking cessation rates with behavioural treatment, behavioural + pharmacological treatments and compare the differences between each approaches. 371 smokers were prospectively evaluated between 2004 and 2008. At the beginning subjects were classified into two groups: behavioral treatment group (I) and pharmacological + behavioural treatment group (II). Numbers of patients per group were 88 and 283 respectively. According to pharmacological therapy group II was also divided into three subgroups: nicotine replacement treatment (NRT) (regardless of the type and dosage) (IIa), bupropion (IIb) and combination treatment modalities group (IIc). Numbers of patients per subgroups were 185, 70 and 28 respectively. All of the patients were attended the one year follow up visits. According to the baseline characteristics there was no significant difference between the groups and subgroups. At the end of the fist year, in group I smoking cessation rate was 41% and in group II 51% and this was not statistically significant (p< 0.05). In the sub group analysis the success rates for group IIa, IIb and IIc; 44.8%, 62.8% and 64% respectively and bupropion is significantly superior to the NRT (p= 0.01). In study subjects, smoking cessation rates were less with comorbid diseases (p= 0.004), baseline airway obstruction (p= 0.04) and high CO levels (p= 0.008). Results of this analysis confirm that, there is a significant difference between pharmacological treatment and behavioral treatments. Additionally, in the pharmacological approaches, bupropion seems to be superior. Besides, comorbid conditions have been a huge problem to solve.

BACKGROUND: Asymptomatic airway hyperreactivity in allergic rhinitis is a risk factor for later development of asthma. Although non-specific bronchial hyperresponsiveness (BHR) has been measured by several stimuli, the most appropriate measurement technique still remains unclear. OBJECTIVE: To investigate whether an exercise challenge can be used to predict BHR in seasonal allergic rhinitis patients with or without asthma and to compare this bronchial reactivity with a methacholine challenge technique. METHODS: Forty-six consecutive patients with seasonal allergic rhinitis only (n = 31) and with both seasonal allergic rhinitis and asthma (n = 15) were included in the study during the pollination period. Subjects underwent first methacholine (mch) and then exercise challenge testing (ECT). There was a 1-week interval between the tests. ECT was performed on a bicycle ergometer. Positive result was defined as a 15% decrease in forced expiratory volume in 1 second (FEV(1)) post-exercise. A patient's bronchial reactivity to methacholine was considered as hyperresponsive if PC(20) was less than 8 mg/mL. RESULTS: Mch PC(20) values were significantly lower in patients with both rhinitis and asthma (p < 0.062). Among the 46 patients, mch PC(20) values were significantly different between patients who had positive and negative exercise challenge tests (p = 0.007). All patients with rhinitis alone had a negative ECT and 10 had a positive mch challenge. Change in FEV(1) values after ECT was significantly higher in patients with both rhinitis and asthma compared to those with rhinitis alone (p = 0.009). There was a significant relation between positivity of mch and exercise challenges (p = 0.025). ECT positivity was found to be a significant confounding factor in the diagnosis of asthma (p = 0.001). Specificity and sensitivity values were 100% and 24% for ECT and 68% and 100% for mch, respectively. CONCLUSION: Exercise challenge presents poor diagnostic value for detecting bronchial responsiveness in individuals with allergic rhinitis alone during the pollen season.

RESUMO
BACKGROUND: Sleep-related breathing disorders (SRBD) are frequently encountered health problems in the general population. Habitual snoring and obstructive sleep apnea/hypopnea syndrome (OSAHS) constitute most SRBD diagnoses. Although the decrease in quality of life is a well-known entity in SRBD patients, there is not enough data regarding the underlying pathophysiological mechanisms to explain this deterioration. OBJECTIVES: The aim of this study was to investigate which parameters were affecting the quality of life in patients with SRBD. METHODS: Medical Outcome Survey - Short Form 36 (SF-36) and Epworth Sleepiness Scale were used in 135 patients with SRBD (69 patients with OSAHS and 66 patients with habitual snoring), and Charlson comorbidity index was calculated. Acquired data were compared with leading symptoms and polysomnographic findings in these patients. RESULTS: All SF-36 scores were significantly decreased in SRBD patients. However, there were no significant differences in the SF-36 scores of these patients. Also, no significant correlation was found between the severity of OSAHS and the SF-36 scores. Similarly, none of the polysomnographic parameters was found significantly correlated with SF-36 scores. In contrast, all SF-36 scores were influenced by body mass index, Epworth Sleepiness Scale score, mean nocturnal saturation and the presence of coexisting diseases. CONCLUSIONS: According to the results of multiple variance analysis, we concluded that the quality of life depends on a number of collaborative factors such as obesity, mean nocturnal saturation, symptoms related to SRBD and the presence of comorbid diseases, rather than only on one independent parameter in the patients with SRBD.

INTRODUCTION: In 2017 update, GOLD separated spirometry from ABCD classification. OBJECTIVES: The aim was to investigate the predictive reliability of GOLD 2017 grading system in terms of future moderate and severe exacerbations. METHODS: COPD patients were classified into A to D groups according to GOLD 2011 and 2017. Patients who were assigned to C/D groups according to GOLD 2011 were divided into subgroups C 1/D1, C2/D2, C3/D3 according to FEV1 % of predicted and exacerbation history. C1/D1 patients defined as FEV1 < 50% predicted and without ≥2 exacerbations or hospitalization in the last year. RESULTS: A total of 225 patients were enrolled. Among them, 25.8% were in groups C1/D1 according to GOLD 2011. These patients shifted to A/B according to GOLD 2017. C1/D1 patients had a significantly higher risk of future moderate and severe exacerbation compared to A/B (P = 0.018). The risk of future moderate and severe exacerbation was significantly higher in patients with a FEV1 < 50% (P = 0.018).The risk of future moderate and severe exacerbation was higher in GOLD 2017 groups A and B compared to GOLD 2011 groups A and B. CONCLUSION: Low FEV1 was an important risk factor for future exacerbations. Downstaging of C1/D1 patients caused heterogeneity in A/B with including patients with low and high risk of future exacerbation. This resulted in a low discriminative power of GOLD 2017 regarding the risk of future exacerbation in groups A and B. This may cause underestimation of disease severity and inadequate treatment especially in A/B patients with low FEV1 .

BACKGROUND: Bronchiectasis is a common disabling but rarely fatal disease. However the long-term prognosis and risk factors for mortality are not well known. OBJECTIVE: The aim of this study was to determine prospectively the survival and predictive factors of mortality in patients with bronchiectasis, during 4-year follow-up. PATIENTS AND METHODS: From September 2000 to January 2005 survival of bronchiectasis (as evaluated by computed tomography) and predictors of mortality were assessed in 98 outpatients. Fifty-one of the patients had self-reported history of pulmonary infection including tuberculosis. Baseline data, reevaluated in every single year according to scheduled visits. RESULTS: The mean age was 61+/-10 and 74% of the patients were female. In total, 16 patients (16.3%) died; mean survival time was 44.06+/-1.6 months. The survival rates were 97%, 89%, 76%, 58% at 1, 2, 3 and 4 years, respectively. Cox proportional hazard model revealed that long-term mortality was significantly associated with age, body mass index (BMI), Medical Research Council (MRC) dyspnea scale, vaccination, radiographic extent, hypoxemia, hypercapnia and functional parameters. However, MRC and BMI had more significant effects on the mortality than the functional parameters. CONCLUSIONS: These results suggest that high BMI, regular vaccination and scheduled visits may have beneficial effects on the survival of bronchiectasis. Besides, presence of hypoxemia, hypercapnia, dyspnea level and radiographic extent were more closely correlated with mortality.

OBJECTIVE: Side effects of the most commonly used primary antituberculosis (anti-TB) drugs may be mild as well as fatal. The aim of this study was to evaluate the side effects of and the risk factors for developing side effects against anti-TB drugs. PATIENTS AND METHODS: Records of 1149 patients with established tuberculosis who initially received anti-TB therapy were evaluated retrospectively. The major side effects, which resulted in a definitive termination from 1 or more drugs related to anti-TB therapy, and the risk factors associated with these side effects, were analyzed. RESULTS: Ninety-five patients (8.3%), constituting 104 cases in total, experienced side effects. Although the frequency of drug reactions were increased from 0.6% at ages <20 to 5.2% at ages 20-40, no gender or age differences were observed between patients who did and did not have side effects. While asymptomatic liver function disturbance was established in 56 of the patients (4.9%) with initiation of anti-TB therapy, the rate of hepatotoxicity was found to be 2.4% in this present study. No age or gender differences were observed among those who had hepatotoxicity and who had not. The major side effects were ototoxicity (1.7%), hepatotoxicity (0.8%), neuropsychiatric manifestations (0.7%), and hyperuricemia (0.6%). CONCLUSIONS: It must be remembered that severe side effects associated with anti-TB drugs were encountered with different frequencies especially among patients hospitalized for pulmonary tuberculosis, and these patients should be followed up by closer monitoring for side effects related to anti-TB drugs.

OBJECTIVE: To analyze the factors affecting survival of patients with chronic obstructive pulmonary disease (COPD) during the follow-up period using a 4-year prospective study. METHODS: The study included 276 out-patients with COPD. The study took place in Ankara University, Cebeci Hospital, Ankara, Turkey between September 2000 and January 2005. We used cox proportional hazards model in investigating the effects of clinical variables on survival. Risk factors related with mortality were analyzed. RESULTS: Forty-nine patients (17.8%) died and the mean survival time was 43.40 +/- 0.65 months. The survival rates were 97% at one year, 89% at 2 years, 84% at 3 years, and 73% at 4 years. Cox proportional hazard model revealed that long-term mortality was significantly associated with age (relative risks [RR]: 1.13, 95% confidence interval: 1.09-1.17), the level of dyspnea (RR: 1.99, 95% confidence interval: 1.44-2.74), the number of hospital admission for acute exacerbation of COPD (RR: 1.33, 95% CI: 1.07-1.67) and the number of scheduled physician visits (RR: 0.75, 95% CI: 0.58-0.95). Also, the presence of hypoxemia was correlated with survival of COPD patients (RR: 0.99, 95% CI: 95-1.00). CONCLUSION: Patient's age, level of dyspnea, hypoxemia and the number of hospital admission were more closely correlated with mortality in COPD. The regular follow-up patients increased the survival of this disease. According to this study patients with COPD may be followed in the specialized out-patient COPD clinics to decrease their morbidity and mortality rates.

Idiopathic pulmonary arterial hypertension (IPAH) is an uncommon and devastating disease which, if untreated, progresses rapidly and leads to right heart failure and death. The course of the disease has been altered by advances in medical therapies. However, the effects of long-term alternative therapies and responses to each treatment protocols are not definite. We want to define an IPAH case, which had long-term temporary responses to the conventional therapy plus calcium channel blockers treatment and moreover compared the long-term clinical and physiologic effects of oral sildenafil mono therapy and additional inhaled iloprost therapy. Patients with IPAH may have response to a short-term vasodilatation therapy but they have to follow for the long-term results and may be of benefit from combination treatments.

The effects of anticholinergic agents or long acting beta(2)-agonists on exercise capacity in chronic obstructive pulmonary disease (COPD) improves various out come measures but there is not enough double-blind study which included comparison of different medications. The aim of this study was to compare the effect of ipratropium bromide and formoterol on exercise capacity and also to determine the relationship between this improvement in functional parameters and exercise capacity for each treatment in patients with COPD. This study was performed as randomized, double blind and two period crossover design. Ten volunteer stable COPD patients were recruited from outpatient COPD clinic. At the initial visit medical data were recorded. One week later baseline measurements; pulmonary function tests and cardiopulmonary exercise testing were performed, afterwards, patients received ipratropium bromide 40 microg four times a day or formoterol 12 microg two times a day for two weeks. After a washout period, medications were crossed for another two weeks. After each of treatment period, all tests were performed. Nine subjects were male and mean age was 51.1 +/- 5.45 years, all of them were heavy smokers, level of COPD was mild to moderate (FEV(1)= 69%, FEV(1)/FVC= 68%). While formoterol significantly improved FEV(1), FEV(1)/FVC %, ipratropium significantly improved FEV(1), FEF(25-75), peak oxygen uptake and minute ventilation. Moreover, both of the medications increased exercise time. There were no differences between effects of ipratropium bromide and formoterol on exercise capacity and functional parameters. We observed that ipratropium bromide and formoterol have similar improvement in exercise capacity in COPD patients. The improvement in exercise capacity also correlated with increase in FEV(1).
