Active clinical trials for "Respiratory Tract (Lung and Bronchial) Diseases"

Pulmonary hypertension is a common complication of chronic obstructive pulmonary disease (COPD). It is reported that over half of COPD patients develop pulmonary hypertension. COPD and pulmonary hypertension may have pathological or genetics interactions so that patients having both disorders tend to have poor prognosis. Echocardiography is widely used to detect pulmonary hypertension, but it's not accurate enough. Therefore, high-quality data reflecting the prevalence, disease course and outcome of pulmonary hypertension in COPD is very limited in China. The aim of the study is to detect pulmonary hypertension with right heart catheterization, describe its outcome in Chinese COPD patients and explore the underlying interaction mechanism.

This cross-sectional study, utilizing two sets of questionaire designed for patients and physicians respectively, aims at the epidemiology, the clinical features, and the current status of evaluation and management of lung cancer related pain in 20 participating hospitals in Northern China.

Malignant pleural effusion is a common clinical problem with median survival of approximately 6 months thus efficient management of Malignant pleural effusion is important. In patients with a Trapped Lung, pleurodesis will be unsuccessful and an indwelling pleural catheter should be inserted instead. Accurate detection of Trapped Lung prior to insertion would avoid futile attempts at talc pleurodesis, re-intervention following failed pleurodesis and allow adequate time to plan for an indwelling pleural catheter insertion.Pleural manometry allows direct and objective measurement of intra-pleural pressure during pleural fluid aspiration.The primary aim of this study is to determine whether the addition of digital pleural manometry to clinical judgment, prior to and during local anaesthetic thoracoscopy, results in a clinically meaningful improvement in Trapped Lung detection.

LUNG-EST is a retrospective study including 152 patients who benefit from lung surgery during the years 2012 to 2013 at Hospices civils de Lyon and with a diagnosis of lung adenocarcinomas. For all patients, clinical data and histopathological data are available. The objective of this study is to characterize these lung adenocarcinomas by the LungCarta Panel using the mass spectrometry array Sequenom. This panel could identify 214 DNA mutations and/or frameshift insert/deletion among 26 oncogenes. Once included in the study, the adenocarcinomas are also included in a Tissue MicroArray (TMA) in order to perform immunohistochemical analysis. Immunohistochemical staining with innovative antibodies are correlated with clinical, histopathological and molecular data. Our hypothesis is that this TMA could constitute a good tool to screen interesting protein's expression.

Program： Clinical Study of Relationship Between Granulocyte Activation, HDAC2 and Severe Asthma Aim：The early prediction of severe asthma, early intervention on the disease, reduce the family and the national finance. design:This study is a single center randomized controlled trial designed by the Department of respiratory medicine, Xijing Hospital, as the main research unit.Compare the case group(severe asthma group and mild-and-moderate asthma group) and control group(healthy control group) by detecting the activity of MPO、NE、MMP-9 and ECP in the peripheral blood and the activity of HDAC2 in PBMCs of patients. case:60 Case selection: Inclusion criteria: age 18-75 years old; diagnosis of asthma was clear; informed consent was signed. Exclusion criteria: poor compliance; cognitive ability is low; psychiatric disorders need to be combined with psychotropic medication.

EPICAL 2 (Epidemiology and prognostic of the Acute Heart Failure) is an epidemiological, observational, prospective and multicenter study. This study includes at first an exhaustive recording of the cases on a geographic area at East of France, then the recorded patients are followed up in a cohort at least 3 years. This study follows the experiences of the EPICAL study led by our team. Main objective: To describe the characteristics of the patients affected by acute heart failure and to identify prognostic factors, in particular related to care. More exactly : To describe the sociodemographic, clinical, biological and therapeutic characteristics of the patients presenting an acute heart failure during hospitalisation and living at East of France ; To study the short and medium-term morbi-mortality of these patients, and identify the main factors determining the prognosis for survival ; To evaluate the prognostic impact of the intra and extra-hospital care ; To identify the evolution of the care's practices of the decompensated heart failure since the EPICAL study (15 years) and their influence on the prognosis of the disease. Secondary objective: to constitute a biological collection of serum, plasma and urine of patients' sample presenting an acute heart failure.

Despite advances in the management of and changes in clinical practice, little is known about the epidemiology, patterns of care and outcomes of rare peritoneal surface malignancies patients in France. In order to better understand the characteristics of rare peritoneal surface malignancies and to evaluate treatment strategies, the RENAPE registry aims at the collection of data from patients presenting with a rare peritoneal surface malignancy in France. Data will be entered prospectively in a specifically designed and secured web database. All RENAPE's centres and physicians are invited to register patients with a rare peritoneal surface malignancy diagnosis and to participate to the registry. Data will be evaluated within regular time frames, focusing on types of rare peritoneal surface malignancies, treatment modalities and patient outcomes (e.g. survival, recurrence), thereby contributing to the better understanding of these rare cancers.

Current diagnostic tools used in pulmonary disease often do not meet the challenges set by the respective pathophysiology. The investigators therefore aimed to evaluate novel or not widely used diagnostic approaches for the detection and therapeutic monitoring of patients with various pulmonary diseases.

Rationale: Accurate staging of lung cancer is important because it directs treatment and determines prognosis. The development of Stereotactic Ablative Radiotherapy (SABR), has revolutionized radiation therapy for early stage lung cancer and results demonstrate similar outcomes in comparison to surgical resection of the lung tumor. The staging work-up program for patients with a potentially resectable Non-Small-Cell Lung Cancer (NSCLC) includes at least a computed tomography (CT) scan of the chest and integrated Positron Emission Tomography - Computed Tomography (PET/CT) scans, and when indicated, invasive mediastinal staging. However, patients who are treated with SABR do not routinely undergo the same nodal staging work-up as do surgical candidates. As both surgery and SABR appear to achieve comparable rates of local and regional tumor control, it appears only logical to perform a similar staging work-up in all patients with early stage lung cancer who will be treated with either of the two curative local modalities. In the past, a lack of invasive nodal sampling before SABR was considered acceptable as invasive surgical staging (mediastinoscopy) was widely considered the preferred procedure. However, with minimally invasive and safe endosonography procedures now available, improved pre-treatment staging has become possible for patient groups who are eligible for SABR, including those with significant comorbidities. Hypothesis: Complete endosonographic (combined endobronchial and esophageal) staging of hilar and mediastinal lymph nodes in patients with (suspected) non-small cell lung cancer (NSCLC) will result in change of loco-regional nodal status in 20% of patients, in comparison to staging by PET-CT alone. Study population: Patients with either established or suspected early-stage NSCLC who are medically inoperable, or who refuse surgery but are potential candidates for SABR with curative intent (provided no intrathoracic metastases are present). Patients will undergo a single scope complete mediastinal and hilar staging procedure (combined EndoBronchial UltraSound (EBUS) and Transesophageal Endoscopic Ultrasound with EBUS scope (EUS-B)).

This study aimed to evaluate the upstream events of Th17/Treg imbalance in CRS and their immune regulatory factors. Then the investigators aimed to explore the regulatory role of miRNA on DC-Th axis and its dysfunction in the pathogenesis of CRS, in order to determine the miRNA expression profile in CRS and clarify the role of miRNA in the pathogenesis of CRS by regulating the DC-Th axis.
