Active clinical trials for "Bronchitis"

This study was advocated by Institute of Basic Research in Clinical Medicine, China Academy of Chinese Medical Sciences in October 2011. It was funded by China major scientific and technological specialized project for 'significant new formulation of new drugs'. Xiyanping is kind of Chinese Medicine injection used for treating viral pneumonia 、bronchitis、amygdalitis、infantile diarrhea、bacillary dysentery 、virus hepatitis、and Children acute hot diseases in many Chinese hospitals. The purpose of this study is to determine adverse drug events or adverse drug reaction in large sample size 20,000 patients.

This study was advocated by Institute of Basic Research in Clinical Medicine, China Academy of Chinese Medical Sciences in January 2013. The purpose of this study is to make a event monitoring to see whether Reduning injection is safe and the characteristic and mechanism of anaphylactic reaction used Reduning injection in hospitals in China.

Cigarette smoking causes an increase in inflammation in the lungs. In about 20% of smokers this inflammation leads to damage in lungs including making holes in the lung tissue. This damage can not be repaired and these people find it very difficult to breathe. One of the problems with this disease called chronic obstructive pulmonary disease, or COPD for short, is that by the time patients visit their doctor with symptoms, the damage has already been done. At the moment, there is no way to predict which smokers will go on to develop COPD. The aim of this research is to look at smokers who breathe normally and use an imaging technique called a CT scan, to look at their lungs in more detail. Some of these people will have spots on their scan which may be caused by inflammation. We want to look at the cells at these spots to see if they make more proteins and enzymes that cause lung damage when compared to people that do not have these spots. We would then be able to predict which smokers are likely to develop COPD and treat them early before they have damaged their lungs.

The study consist of a retrospective analysis of the etiologies, investigations and outcomes of patients presenting between 2005 to 2010 with hemoptysis in a North-American Tertiary center.

The ARIES Flu Assay is a real-time PCR based qualitative assay for the direct detection and differentiation of respiratory viral nucleic acid in nasopharyngeal swabs specimens. The objective of this study is to establish the diagnostic accuracy of ARIES Flu Assay.

Acute dyspnea after use of non-invasive ventilation (NIV) is a common phenomenon in patients with COPD and emphysema. This trial aims to document incidence and severity of augmented dyspnea in patients with long term NIV therapy. These findings may help in understanding the pathomechanisms that lead to post-NIV dyspnea and thus give way to potential therapy schemes.

The investigators hypothesized that acute bronchitis will be associated with various bacteria and viruses.

Hypothesis: Innate immunity is altered in certain patients with COPD and frequent exacerbations, a fact that makes them more susceptible to being infected by bacteria. The electronic nose is able to detect patterns of specific VOCs for exacerbations of infectious origin.

The WheezeScan sensitivity and specificity are set to statistically prove equal to or higher values than the predicate PulmoTrack device model 2020.

This study aims to identify and validate the gene expression differentials of peripheral blood mononuclear cells and differential inflammation profiles and other aspects in classic asthma, cough-variant asthma and eosinophilic bronchitis.
