Cancer Of The Lung

Wir berichten über einen 76jährigen Patienten, welcher trotz gut eingestellter oraler Antikoagulation mit Phenprocoumon rezidivierende Thrombosen erlitt bei leichtgradiger chronischer disseminierter intravasaler Gerinnung. Die Abklärungen ergaben das Vorliegen eines Bronchus-Karzinoms (Non small cell cancer of the lung, NSCCL) mit hilären und mediastinalen Lymphknotenmetastasen. Aufgrund der Assoziation von rezidivierenden Thrombosen, aktivierter Gerinnung und Tumorleiden wurde die Diagnose eines Trousseau Syndroms gestellt. Basierend auf Fallberichten aus der Literatur wurde die Therapie auf intravenöses Heparin gewechselt, welches die thrombotische Koagulopathie stoppte. Aus praktischen Gründen erfolgte dann eine Umstellung der Therapie auf subcutanes niedermolekulares Heparin in therapeutischer Dosierung, welches während 6.5 Monaten ebenso effektiv war und eine Alternative zur etablierten Therapie mit unfraktioniertem Heparin bei Trousseau Syndrom darstellen dürfte.

Cancer Of The Lung

Lung cancer is the most commonly diagnosed cancer among men in most countries, and is the primary cause of cancer death in men and women. Its epidemic increase in incidence began in the first half of the twentieth century, paralleling the uptake of cigarette smoking that occurred 20 years before. A series of landmark studies beginning in 1950 established tobacco as the primary cause of lung cancer. Current smokers have a 10- to 20-fold higher lung cancer risk compared to never smokers. Important for prevention, former smokers substantially reduce this excess risk 5 years after smoking cessation. Exposure to secondhand smoke, a well-established risk factor for lung cancer, has a 20%–25% higher risk for those exposed. There are several occupational exposures associated with lung cancer, including asbestos. Despite the success in defining lung cancer’s etiology, this highly preventable disease remains among the most common and most lethal cancers globally.

Cancer Of The Lung

Cancer, responsible for about 1 death in 5 in Scotland, cost over £1 per head of population in 1965 and led to bed occupation of almost 2,000 bed years. Time lag (symptoms-doctor-hospital-treatment) is usuallv small. Age distribution is as in other European countries. Excluding accidents, cancer is the second most important cause of death in children. In relation to other countries Scotland's position is very poor and the lung cancer mortality in both sexes is the highest known. Lung cancer is the most important in males, breast cancer in females. Alimentary cancers come second in both sexes. In this century alimentary cancers increased till the thirties or forties and then declined. Cancers of pancreas, cervix uteri, ovary, prostate, kidney and bladder, together with leukaemia, have all increased. Cancer of the lung has increased elevenfold in women and fiftyfold in men. It now accounts for 9 to 12 per cent of all male deaths in cities and large towns

Introduction. Some studies have found that cilia were shorter in COPD smokers than in nonsmokers or healthy smokers. However, the structural abnormalities of cilia and the cause of such abnormalities in COPD patients still remain unknown. Tumor necrosis factor alpha receptor 3 interacting protein 1 (MIP-T3) may play an important role in the progress of ciliary protein transporting. Objectives. This study aimed at exploring the dominated structural abnormalities of cilia and the involvement of MIP-T3 in the pathogenesis of cilia of COPD patients. Methods. Patients who accepted pulmonary lobectomy were divided into 3 groups: the chronic obstructive pulmonary disease (COPD) smoker group, the healthy smoker group, and the nonsmoker group, according to smoking history and pulmonary function. The ultrastructure of cilia and the percentage of abnormal cilia were analyzed using a transmission electron microscope. Real-time PCR, immunohistochemical staining, and western blotting in bronchial epithelium were used to determine MIP-T3 mRNA and protein expression. The relationship between the percentage of abnormal cilia and lung function and MIP-T3 protein expression was analyzed. Results. Patients in the COPD smoker group had increased percentage of abnormal cilia comparing to both the healthy smoker group and the nonsmoker group (both P values <0.05). MIP-T3 expression was significantly declined in the COPD smoker group (P value <0.05). Moreover, the percentage of abnormal cilia was negatively correlated with FEV1, FEV1/FVC ratio, and FEV1%pred (all P values <0.05). Moreover, the MIP-T3 protein expression was positively correlated with the percentage of abnormal cilia (P value <0.05). Conclusions. Our results suggested that the abnormal ciliary ultrastructure, which was common in COPD patients, might be due to MIP-T3 downregulation.

Primary Bronchial Epithelial Cells

Non-typeable Haemophilus influenzae (NTHi) is the most common respiratory pathogen in patients with chronic obstructive disease. Limited data is available investigating the impact of NTHi infections on cellular re-differentiation processes in the bronchial mucosa. The aim of this study was to assess the effects of stimulation with NTHi on the bronchial epithelium regarding cellular re-differentiation processes using primary bronchial epithelial cells harvested from infection-free patients undergoing bronchoscopy. The cells were then cultivated using an air-liquid interface and stimulated with NTHi and TGF-β. Markers of epithelial and mesenchymal cells were analyzed using immunofluorescence, Western blot and qRT-PCR. Stimulation with both NTHi and TGF-ß led to a marked increase in the expression of the mesenchymal marker vimentin, while E-cadherin as an epithelial marker maintained a stable expression throughout the experiments. Furthermore, expression of collagen 4 and the matrix-metallopeptidases 2 and 9 were increased after stimulation, while the expression of tissue inhibitors of metallopeptidases was not affected by pathogen stimulation. In this study we show a direct pathogen-induced trans-differentiation of primary bronchial epithelial cells resulting in a co-localization of epithelial and mesenchymal markers and an up-regulation of extracellular matrix components.
