MCT and Capsaicin Provocation Challenge in Diagnosis of Chronic Cough

The present study has the following objectives: to assess the prevalence of BHR in non-smoking adults with a chronic cough, to assess the prevalence of BHR in patients with UACS and GERD, to evaluate the relationship between BHR and cough reflex sensitivity, to assess the diagnostic accuracy of MCT in ...

Phase N/A

EXhaled Hydrogen Peroxide As a Marker of Lung diseasE (EXHALE) Pilot Study.

Hydrogen Peroxide levels in Exhaled Breath Condensate (EBC) is a direct biomarker of oxidative stress from the airway epithelium. Levels have been shown to be raised in asthma and Chronic Obstructive Pulmonary Disease (COPD) both in stable and exacerbating states. Previously it has been difficult to measure this volatile compound ...

Phase N/A

The Application of Impulse Oscillometry on the Diagnosis of ACOS Asthma and COPD.

ACOS,asthma and COPD are prevalent diseases with similar manifestations and different type airway impairments. The differential diagnosis is not easy because the patients always complain of the similar symptoms and are not able to complete spirometry well. Impulse Oscillometry System (IOS) is capable of identifying airway obstruction and reactions to ...

Phase N/A

Clinical Characteristics Treatment and Prognosis of Chest Tightness Variant Asthma

Asthma, abbreviation for bronchial asthma, is one of the common chronic airways disease that threatens human health. Typical symptoms of asthma are recurrent wheezing, shortness of breath, chest tightness and cough, usually occurring at night or early morning. However, there are still some patients with only persistent clinical manifestations of ...

Phase N/A

Evaluation of the Effectiveness and Quality of Life With the Administration of the Fixed Combination of Budesonide Formoterol in Greek Patients With Asthma During Routine Clinical Practice.

Asthma is a heterogeneous disease, usually characterized by chronic inflammation of the airways. Characterized by a history of respiratory symptoms such as wheezing, chest heaviness and cough symptoms that fluctuate over time, as well as variable airway obstruction. Asthma is a common disease worldwide, the rates of which are increasing ...

Identifying Patients With the COPD-Asthma Overlap Phenotype: Therapeutic Implications

Background: Asthma and COPD are considered different diseases but many patients share characteristics of both entities. This has been termed "COPD-asthma overlap syndrome". Study objective: To examine: (a) the frequency of the overlap phenotype among patients referred for pulmonary function testing and, (b) the impact of this phenotype on the ...

Phase N/A

Study of the Frequency and of the Regulatory Function of Positive T Lymphocytes Dual CD4CD8aa (DP8a) Specific to a Bacteria of the Intestinal Microbiota (Faecalibacterium Prausnitzii) in Atopic Dermatitis Asthma and Allergic Rhinitis

The primary endpoint will be the highlight of a quantitative reduction of double positive T cells (CD4 + / CD8 +) the specific F prausnitzii peripheral blood in patients with allergic asthma, allergic rhinitis and atopic dermatitis compared to samples from a control sample collection made available by the laboratory ...

Phase N/A

Identification of Asthma Phenotypes in Severe Asthmatics

Asthma is a heterogeneous disorder presenting with many phenotypes. Most asthmatics have mild to moderate disease. However, 5-20% of asthmatics belong to the "Difficult-to-treat" or more severe group and they account for 50-80% of asthma health care costs. In a tertiary hospital like Singapore General Hospital, most of our asthmatics ...

Phase N/A

Childhood Asthma Management in Primary Care: Implementation Of Exhaled Nitric Oxide and Spirometry Testing

What are the capacity and training needs in general practice to implement routine spirometry and eNO testing in children aged 5-16 years? Asthma is the commonest long-term disease of childhood in the United Kingdom (UK). Under-diagnosis and under-treatment of childhood asthma in general practice (GP) have been reported from several ...

Phase N/A

Gene Expression Profile and Inflammation Profile of Classic Asthma Cough Variant Asthma and Eosinophilic Bronchitis

Asthma is a common and heterogeneous respiratory disorder affecting millions of people, posing a considerable burden on health care systems globally. The disease is characterized by inflammation of the airways with eosinophils, neutrophils, mast cells, lymphocytes, airway epithelial cells, smooth muscle cells and other cells, by airflow obstruction and by ...
