RESUMO
OBJECTIVE: To investigate the symptoms of lung cancer in Turkey and to evaluate approaches to alleviate these symptoms. SUBJECTS AND METHODS: This study included 1,245 lung cancer patients from 26 centers in Turkey. Demographic characteristics as well as information regarding the disease and treatments were obtained from medical records and patient interviews. Symptoms were evaluated using the Edmonton Symptom Assessment Scale (ESAS) and were graded on a scale between 0 and 10 points. Data were compared using the χ2, Student t, and Mann-Whitney U tests. Potential predictors of symptoms were analyzed using logistic regression analysis. RESULTS: The most common symptom was tiredness (n = 1,002; 82.1%), followed by dyspnea (n = 845; 69.3%), appetite loss (n = 801; 65.7%), pain (n = 798; 65.4%), drowsiness (n = 742; 60.8%), anxiety (n = 704; 57.7%), depression (n = 623; 51.1%), and nausea (n = 557; 45.5%). Of the 1,245 patients, 590 (48.4%) had difficulty in initiating or maintaining sleep. The symptoms were more severe in stages III and IV. Logistic regression analysis indicated a clear association between demographic characteristics and symptom distress, as well as between symptom distress (except nausea) and well-being. Overall, 804 (65.4%) patients used analgesics, 630 (51.5%) received treatment for dyspnea, 242 (19.8%) used enteral/parenteral nutrition, 132 (10.8%) used appetite stimulants, and 129 (10.6%) used anxiolytics/antidepressants. Of the 799 patients who received analgesics, 173 (21.7%) reported that their symptoms were under control, and also those on other various treatment modalities (dyspnea: 78/627 [12.4%], appetite stimulant: 25/132 [18.9%], and anxiolytics/antidepressants: 25/129 [19.4%]) reported that their symptoms were controlled. CONCLUSION: In this study, the symptoms progressed and became more severe in the advanced stages of lung cancer, and palliative treatment was insufficient in most of the patients in Turkey.

BACKGROUND: Cigarette smoke with its toxic ingredients leads to chronic inflammations in the airways. OBJECTIVES: In this study, the effect of cigarette smoke on the levels of inflammatory markers, interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor-alpha (TNF-α) in induced sputum was investigated. MATERIALS AND METHODS: Twenty patients with chronic obstructive pulmonary disease (COPD) (group I), 20 healthy smokers (group II), and 20 healthy nonsmokers (group III) were included in the study. The levels of IL-6, IL-8, and TNF-α in induced sputum were measured in these groups, and comparison analysis between the groups and correlation analysis for smoking load (pack-years) and spirometric parameters were performed. RESULTS: Mean age of the patients in groups I, II, and III were 61.2 ± 1.7, 58.2 ± 1.6, and 59.1 ± 5.4 years, respectively (P > 0.05). Smoking loads of group I and group II were 38.6 ± 2.1 and 29.5 ± 2.3 pack-years, respectively (P < 0.05). All cytokine levels were significantly higher in group I than groups II and III (P < 0.05). In addition to this, mean cytokines levels were significantly higher in group II than group III (P < 0.05). Smoking load of group II subjects was positively correlated with IL-6, IL-8, and TNF-α in induced sputum (P < 0.05). CONCLUSIONS: We found that inflammatory marker levels in induced sputum were significantly higher in COPD patients and smokers than nonsmokers. Moreover, there was a moderate positive correlation between IL-6, IL-8, and TNF-α levels and smoking load in the healthy smokers. We think that further studies are needed to determine whether higher levels of cytokine levels in sputum might be helpful in predicting the healthy smokers who will develop COPD in future.

OBJECTIVE: Obstructive sleep apnea syndrome (OSAS) has been associated with elevated biochemical markers of inflammation. Although the exact mechanism is unknown, both sleep deprivation and hypoxemia are believed to be important causative factors. YKL-40, also known as chitinase-like protein, has been shown to be related to various inflammatory conditions including atherosclerosis, diabetes, cancer, and asthma. The present study aimed to evaluate the relationship between YKL-40 levels and the Apnea Hypopnea Index (AHI) in patients with obstructive sleep apnea syndrome. PATIENTS AND METHODS: The study was conducted at the Sleep Unit of the Namik Kemal University Research Center. From January 2013 to December 2013, 120 patients diagnosed with OSAS by polysomnography and 40 subjects without OSAS were recruited. Patients in both groups were matched by age, sex, and body mass index (BMI). They were further divided into groups of mild, moderate and severe OSAS based on their AHI value. Serum YKL-40 concentrations were measured by the enzyme-linked immunosorbent assay (ELISA). RESULTS: OSAS patients showed significantly elevated YKL-40 levels compared to the control group; 102,05 (23.14) pg/ml in the control group vs. 144.81 (65.53) pg/ml in the OSAS group. A Spearman correlation analysis showed that serum YKL-40 levels were significantly and positively correlated with AHI (r = 0.434, p < 0.001) and oxygen desaturation index (r = 0.374, p < 0.001). CONCLUSIONS: The study demonstrated that high serum YKL-40 levels correlated with the severity of OSAS and might serve as a nonspecific biomarker for prediction and progression of the disease.

OBJECTIVE: Copeptin is a precursor of AVP, an antidiuretic hormone, plays a pivotal role in the maintenance of cardiovascular homeostasis. Obstructive sleep apnea syndrome (OSAS) is related to cardiovascular disease. We sought to evaluate the serum copeptin levels in newly diagnosed prehypertensive patients with OSAS. PATIENTS AND METHODS: Eighty-four prehypertensive patients were evaluated using polysomnography and were divided into two groups, an OSAS (n = 41) group and a control (n = 43) group. Serum copeptin levels were measured using the ELISA method. RESULTS: Copeptin levels were significantly higher in the OSAS group compared to the control group (146 [93-739] pg/ml vs. 111 [33-253] pg/ml, respectively, p < 0.001). A regression analysis revealed that the apnea hypopnea index (AHI) and the lowest SpO2 were related to serum copeptin levels (unstandardized ß = 1.02 ± 0.40, p = 0.014 and unstandardized ß = -3.1 ± 0.9, p = 0.048 respectively). CONCLUSIONS: According to the results of our study, serum copeptin levels are higher in the prehypertensive patients with OSAS compared to those in the control group. Therefore, in assessing the severity of OSAS, serum copeptin levels can be a candidate for a biochemical marker in addition to polysomnographic findings.

The present study was designed to evaluate the hypothesis that nebulised budesonide (NB) might be an alternative to systemic corticosteroids (SC) in the treatment of patients with exacerbations of chronic obstructive pulmonary disease (ECOPD). Patients hospitalised with ECOPD (n = 159) were randomised into three groups. Group 1 received only standard bronchodilator treatment (SBDT), group 2 received SC (40 mg prednisolone) plus SBDT, and group 3 received NB (1,500 microg q.i.d.) plus SBDT. Improvement during 10-day hospitalisation was compared with exacerbation and rehospitalisation rates after discharge. While mean+/-sd age was 64.1+/-8.9 yrs (female/male = 0.1), mean forced expiratory volume in one second (FEV(1)) at admission was found to be 37.2+/-12.2% predicted. Arterial blood gases and spirograms recovered faster in groups 2 and 3. While improvements in arterial oxygen tension (P(a,O(2))) and forced vital capacity (FVC) in group 2, and improvements in P(a,O(2)), FVC and FEV(1) in group 3, became significant at 24-h control, the first significant improvement in group 1 appeared in arterial oxygen saturation at 72-h control. The mean improvement of P(a,O(2)) after 10 days was 1.20 and 1.06 kPa (9 and 8 mmHg) higher in group 2 and 3, respectively, than in group 1. Blood glucose exhibited an upward trend only in group 2. The study demonstrates that nebulised budesonide may be an effective and safe alternative to systemic corticosteroids in the treatment of exacerbations of chronic obstructive pulmonary disease.

Factors determining in-hospital mortality and long-term survival of patients hospitalised with acute exacerbations of chronic obstructive pulmonary disease (AECOPD) are not precisely understood. The aim of the present study was to assess the parameters related to in-hospital mortality and long-term survival after hospitalisation of patients with AECOPD. Clinical and epidemiological parameters on admission in 205 consecutive patients hospitalised with AECOPD were prospectively assessed. Patients were followed-up for 3 yrs. Factors determining short- and long-term mortality were analysed. In total, 17 patients (8.3%) died in hospital. In-hospital mortality was significantly associated with lower arterial oxygen tension (P(a,O2)), higher carbon dioxide arterial tension, lower arterial oxygen saturation and longer hospital stay. The overall 6-month mortality rate was 24%, with 1-, 2- and 3-yr mortality rates of 33%, 39% and 49%, respectively. Cox regression analysis revealed that long-term mortality was associated with longer disease duration (relative risk (RR) = 1.158), lower albumin (RR = 0.411), lower P(a,O2) (RR = 0.871) and lower body mass index (RR = 0.830). When the model was run for the time elapsed since first hospitalisation, it also appeared as statistically significant (RR = 1.195). These findings show that patients hospitalised with acute exacerbations of chronic obstructive pulmonary disease have poor short- and long-term survival. Prediction of survival status may be enhanced by considering arterial oxygen tension, albumin, body mass index, disease duration and time elapsed since the first hospitalisation.
