Introduction/Objective The origin of depressive disorder in chronic obstructive pulmonary disease (COPD) patients is still not completely known and probably is caused by various factors. The aim of this study is to establish the most important characteristics of COPD patients who have depressive disorder. Methods Eighty-nine COPD patients and 65 demographically-matched referents without COPD were included. All the patients underwent lung function examination, and gas exchange, nutritional status, dyspnoea level by the modified Medical Research Council (mMRC) scale and exercise tolerance were also assessed, as well as depressive disorder by Hospital Anxiety and Depression Scale (HADS) and Geriatrics Depression Scale (GDS) and quality of life by St. George’s Respiratory Questionnaire (SGRQ). Results Depressive disorder has been found in 30.3% of COPD patients evaluated by HADS and 25.3% of COPD patients evaluated by GDS. When COPD subjects were stratified by forced expiratory volume in 1 second (FEV1) categorization, all subgroups were more likely to have depressive disorder, according to HADS and GDS, relative to referents with the odds ratio highest (3: 95% confidence interval 1.6–4.9) among those with the FEV1 < 30%. COPD patients with depressive disorder (HADS) compared to non-depressed patients had (differences in mean values) higher intensity of smoking [6.9 (0.5–10.1)], lower body mass index [-4.9 (-7.2–5.4)], lower value of FEV1% [-8.3 (-16.3–1.2)], higher value of total lung capacity (%) [17.8 (2.3–28.4)], higher mMRC score (1.07 (-1–3.0), and higher SGRQ – giving a total score of 32.9 (24.1–40.3). Conclusion Evaluation of depressive disorder should be considered in every patient with COPD, especially in patients with greater degree of airflow limitation and lung hyperinflation, dyspnoea level and malnourished. © 2017, Serbia Medical Society.

Lung cancer is the most common cancer, and small-cell lung cancer (SCLC) accounts for around 20 % of lung cancers. SCLC has a neuroendocrine cellular origin, and the tumor cells usually express neuroendocrine markers. There have been major recent advances in the management of SCLC, and multimodal approaches are now the norm. An improved knowledge of the prognostic variables would assist in defining which patients were better candidates to receive these newer intensive therapies. This single-center retrospective study of 97 previously untreated and histologically proven SCLC patients analysed the circulating neuroendocrine markers chromogranin A (CGA), pro-gastrin-releasing peptide (ProGRP), and neuron-specific enolase (NSE) in addition to the other more classical variables. Fifty patients had limitedstage disease and 47 had extensive disease. Sixty patients had an ECOG performance status (PS) of 0-1 and 37 had PS 2-4. Median survival for the whole study population was 13 months. Univariate analysis and univariate Cox regression modeling found a statistically significant association between survival and PS, disease stage, and CGA, ProGRP, and NSE levels. Age and sex were not prognostic. A shorter survival time was found in patients with a PS equal to or >2, extensive stage disease, a serum CGA level >56 ng/ml, a serum ProGRP level >58 pg/ml, and a serum NSE level >19 ng/ml. This study has found that there is a potential role for ProGRP, NSE, and CGA in both staging and prognosing survival in SCLC patients. © Springer Science+Business Media New York 2013.

Background/Aim. Hyperreactivity of the airways caused by inflammation in asthmatics is the most important pathophysiological change. It represents a suitable ground that in the presence of risk factors and the drivers of asthma, asthmatic attack occurs. Atopic constitution is one of the most important risk factors for the development and expression of asthma. The aim of our study was to investigate the relationship between nonspecific airway hyperreactivity and atopic constituton in asthmatics. Methods. This retrospective analysis was conducted considering the results of nonspecific bronchoprovocative test with histamine, skin tests to inhalant allergens and total IgE levels in the serum of asthmatic patients with controlled bronchial asthma. The sample consisted of 162 asthmatics examined during one-year period. Results. The examinees were male asthmatic patients, aged between 18 and 30 years. We found that the examinees with a pronounced non-specific hyperreactivity had more significant skin reaction to inhaled allergens and higher levels of total IgE in serum. Conclusion. The results of our study show that the intensity of airway hyperresponsiveness to histamine in asthmatics is directly related to atopic constitution. © 2016, Institut za Vojnomedicinske Naucne Informacije/Documentaciju.
