[Chronic thromboembolic pulmonary hypertension--a position paper]. / Chronisch thromboembolische pulmonale Hypertonie (CTEPH) 2014. Ein Positionspapier.

This position paper summarises current developments in chronic thromboembolic pulmonary hypertension (CTEPH) including diagnostic approaches and treatment options. Based on the guidelines of the task force of CTEPH experts at the 5th World Symposium on Pulmonary Hypertension in Nice 2013. Open questions arising during the treatment of patients with CTEPH are addressed. Patients with suspected CTEPH should undergo echocardiography and cardiopulmonary exercise testing. A ventilation/perfusion scan is the recommended imaging test for screening in the diagnostic algorithm for the evaluation of CTEPH. CTEPH-patients should be discussed in an expert center with an interdisciplinary team and an experienced PEA surgeon to decide the further treatment. Pulmonary endarterectomy (PEA) is the treatment of choice for patients with CTEPH. Medical therapy with PH-targeted medications for inoperable CTEPH and residual disease after PEA should only be initiated if evaluation reveals that the patient is no candidate for a PEA. Current data suggest that CTEPH patients treated with PEA have a better long-term survival rate and quality of life than patients treated with medical therapy.

[Prognostic Relevance of the Metastatic Localisation in Patients with Stage IV NSCLC - Results of a Prospective Epidemiological Study]. / Prognostische Relevanz der Metastasenlokalisation bei nicht kleinzelligem Bronchialkarzinom im Tumorstadium IV - Ergebnisse einer prospektiven epidemiologischen Studie.

Patients with non-small cell lung cancer (NSCLC) frequently suffer from stage IV disease at the time of presentation. Survival of these patients is disadvantageous although they may benefit from chemotherapy. The main purpose of this investigation was to evaluate the prognostic relevance of the metastatic localisation in unselected patients. The second purpose was to evaluate the impact of clinical characteristics on the kind of decision-making in patients with stage IV NSCLC in an epidemiological manner.[nl]Clinical data as well as survival of 336 patients with stage IV NSCLC were analysed. The recruitment period was 3? years, mean follow-up was 24 months. This investigation was part of the HALLUCA studies which were sponsored by the German Ministry of Health.[nl]Localisation-dependent median and 1-year survivals were significantly different and varied between 2.2 months and 4.7 % (liver metastases) and 11.0 months and 44.5 % (lung metastases). The different survival remained significant in the multivariate analyses with age, performance status, treatment and histology as co variables. The chemotherapy rate of all patients with stage IV NSCLC was 39 %. Patients with liver, bone and multiple metastases received less often chemotherapy compared to patients with other metastases although the performance status was not different to the other groups.[nl]Although there are some limitations in this investigation, these epidemiological data demonstrate the prognostic heterogeneity of stage IV NSCLC patients which should be considered for stratification in controlled clinical trials. Regional treatment decision-making is different from guidelines and controlled clinical trials. Further regionally orientated trials are necessary to improve the transformation from clinical trials to regional medical care.

[Treatment of respiratory papillomatosis--a case report on systemic treatment with bevacizumab]. / Behandlung der respiratorischen Papillomatose--Kasuistik zur systemischen Therapie mit Bevacizumab.

BACKGROUND: Recurrent respiratory papillomatosis (RRP) is a known but rare disease, caused by human papilloma virus and characterised by multiple exophytic lesions and uncontrolled growth of papilloma in the respiratory tract. The most common complication of RRP is stenosis of the trachea. Medical therapeutic options have so far been less effective. However, inhibition of vascular endothelial growth factor (VEGF) by bevacizumab does appear to be an effective treatment option for RRP. CASE REPORT: The case of a 32-year-old male patient with RRP who has been treated for his symptomatic tracheal stenosis four times a year since 1996 is described. Only treatment by laser ablation showed any efficacy. Alternative treatment options did not show any effect. In May 2006 intrapulmonary lesions of RRP were also diagnosed but without any malignancy. From December 2007 to June 2008 the patient has been treated with bevacizumab. A visible regression of RRP and markedly less symptoms were observed. During this treatment no further laser ablation was necessary. CONCLUSION: Inhibition of VEGF by bevacizumab seems to offer a new and effective option in the medical management of RRP.

[Palliative care in respiratory medicine]. / Palliativmedizin in der Pneumologie.

Palliative care should be part of respiratory medicine for two reasons: first, many respiratory diseases--besides thoracic tumours--need palliative care in the late stages of the disease. Second, dyspnoea is a common symptom in advanced, primary extrapulmonary diseases and the knowledge of respiratory specialists can be beneficial in the treatment of this symptom. In this paper we describe frequent symptoms of advanced pulmonary diseases and their treatment. Moreover, we focus on the structure of palliative care in Germany.

[Cardiac efficiency in patients with Cheyne-Stokes respiration as a result of heart insufficiency during long-term nasal respiratory treatment with adaptive servo ventilation (AutoSet CS)]. / Kardiale Leistungsfähigkeit bei Patienten mit Cheyne-Stokes-Atmung infolge Herzinsuffizienz während langfristiger nasaler Beatmungstherapie mittels adaptiver Servoventilation (AutoSet CS).

Cheyne-Stokes respiration (CSR) is known to be an important negative predictor of outcome in patients with congestive heart failure. The goal of this study was to investigate whether the use of adaptive servo ventilation (AutoSet CS) would permit sufficient suppression of this pathological breathing pattern and improve cardiac function in longterm use over 1 year. Inclusion criteria for the study were congestive heart failure (left ventricular ejection fraction 20-50%), proven CSR with a central apnea-hypopnea index (AHI) > 15/h and stable clinical status with standard medical therapy. Patients with obstructive sleep apnea and COPD were excluded. Twenty consecutive patients (16 male) age 65.5 years (range 48-77) were followed with full blood counts, blood gas analysis, lung function tests and questionnaires for cardiopulmonary capacities (Minnesota, MRC Scale) and sleepiness (Epworth Sleepiness Scale). In addition, we performed 6-min walk distance (6MWD), echocardiography and polysomnography just before and after adjusting to adaptive servo ventilation and 3 and 12 months later. Mean usage of adaptive servo ventilation was sufficient (4.3 +/- 2.1 h/day at 12 months). No significant changes in blood gas analysis, blood counts and pulmonary function were detectable. CSR disappeared almost completely in all patients (AHI pre-study 44.3 +/- 13.4/h vs 3.4 +/- 8.0/h at 12 months; p < 0.0001). Saturation normalized steadily over the course of the study. The desaturation index decreased from 45.3 +/- 17.8/h to 5.2 +/- 11.5/h at 12 months (p < 0.0001). Mean saturation increased with the first night of sleep with adaptive servo ventilation from 92.0 +/- 2.5% to 93.0 +/- 1.6% (p < 0.05) and then to 94.1 +/- 1.9% at 3, and 94.2 +/- 1.9% at 12 months (p < 0.001). Quality of sleep was significantly improved with an increase of slow-wave sleep from 4.5 +/- 4.6% to 13.7 +/- 6.9% at 12 months (p < 0.0001). The arousal index concomitantly decreased from 29.8 +/- 17.9/h pre-study to 12.0 +/- 10.3/h at 12 months (p < 0.01). REM-sleep and sleep efficiency remained unchanged. The Epworth Sleepiness Scale showed only a trend to improvement. Cardiac function improved significantly during the course of the study. The ejection fraction increased from mean 37.1 +/- 12.5% pre-study to 41.7 +/- 8.8% at 12 months (p < 0.05). The 6-min walk distance increased from 192 +/- 110 m to 277 +/- 130 m at 12 months (p < 0.01). The MRC and Minnesota score were not significantly different pre- and post-study. We conclude that long-term respirator therapy with adaptive servo ventilation has sufficiently suppressed CSR and improved cardiac function in patients with congestive heart failure. Thus, safety and feasibility of this respirator therapy could be demonstrated. However, due to methodological reasons (no control group, no randomization) a direct effect on cardiac function could not be confirmed.
