    Eosinophilic bronchitis without asthma
    (Karger, 2008) Gonlugur, Ugur; Gonlugur, Tanseli Efeoglu
    Background: Eosinophilic bronchitis without asthma causes chronic coughs without the physiologic features of asthma. The aim of this study was to review the clinical features, pathogenesis, diagnosis, treatment and prognosis of this condition. Methods: The current literature was reviewed using Pubmed for all studies published in the English language using the search term 'eosinophilic bronchitis'. Results: Eosinophilic bronchitis presents as normal spirometry, without evidence of airway hyperresponsiveness, and normal peak expiratory flow variability. When compared with asthma, mast cell recruitment to the superficial airways and mast cell activation appear to be a feature of eosinophilic bronchitis. In contrast, mast cell infiltration in the smooth muscle is significantly higher in asthma patients than in either eosinophilic bronchitis patients or healthy control subjects. In this condition, the absence of high IL-13 expression can contribute to the normal airway reactivity. The cough usually responds well to inhaled corticosteroids but dose and duration of treatment remain unclear. The condition can be transient, episodic or persistent unless treated, and occasionally, patients may require long-term treatment with oral corticosteroids. Conclusions: The condition is an important cause of chronic coughs which are corticosteroid responsive. The study of eosinophilic bronchitis suggests that eosinophil-dependent mechanisms are generally not important in the pathogenesis of asthma. Copyright (C) 2008 S. Karger AG, Basel.

    Pleural fluid findings as prognostic factors for malignant pleural mesothelioma
    (Wiley, 2008) Gonlugur, Tanseli Efeoglu; Gonlugur, Ugur
    The aim of this study was to determine the prognostic value of pleural fluid glucose, lactate dehydrogenase (LDH), albumin, total protein, and total leukocyte levels in patients with malignant pleural mesothelioma. We retrospectively analyzed 71 consecutive patients (33 men and 38 women) who were referred to the department of chest diseases in a university hospital. Pleural fluid glucose levels, the ratio of pleural fluid to serum LDH > 1.0, and total leukocyte count were significant predictors for the survival in univariate analysis. However, none of these variables emerged as statistically significant from the multivariate Cox model. In conclusion, our results showed that there is an inverse correlation between the intensity of inflammation and survival.

    Prognostic Factors for 100 Patients With Malignant Pleural Mesothelioma
    (Heldref Publications, 2010) Gonlugur, Ugur; Gonlugur, Tanseli Efeoglu
    The aim of this study was to investigate the effects of various clinical, laboratory characteristics, and therapeutic modalities on the survival of patients with malignant pleural mesothelioma. One hundred consecutive patients with a pathologically proven diagnosis of malignant pleural mesothelioma treated between 1993 and 2005 were included in the study. Using a Cox proportional hazard model, comorbidity, weight loss, breathlessness, and performance status were identified as independent prognostic factors. Comorbidity had interestingly favorable effect on the survival. Treated patients with chemotherapy had significantly longer survival than those treated with best supportive care. However, it was necessary to complete at least 6 cycles for a survival benefit. In conclusions, comorbidity information should be recorded in the recent prognostic studies. The drugs used for the comorbidity may improve survival.
