Active clinical trials for "Lung Diseases, Obstructive"

Investigating nasal muco-ciliary clearance by scintigraphy

The aim of this prospective observational trial is to evaluate the influence of Coping strategies on pulmonary rehabilitation outcomes like 6-minute walk distance and Quality of life.

Chronic Obstructive Pulmonary Disease (COPD) is a common, preventable and treatable disease that is characterized by persistent respiratory symptoms and airflow limitation that is due to airway and/or alveolar abnormalities usually caused by significant exposure to noxious particles or gases. Acute exacerbations may occur during the management of stable COPD which can negatively impact health status, rates of hospitalization and re-admission. During exacerbation, some patients need immediate admission to the respiratory intensive care unit (RICU) for ventilatory support. As prolonged mechanical ventilation has unfavourable impacts, it is Important to minimize the duration of mechanical ventilation and perform extubation as soon as possible. In recent years, development of numerous models of artificial respiration, which could support spontaneous breathing, has made it possible to gradually decrease the mechanical ventilatory support. From these new modes, PSV which is a well known weaning mode will be compared in our study to a new weaning mode which is a volume support ventilation (VSV).

The overlap between chronic obstructive pulmonary disease (COPD) and bronchiectasis is a neglected area of research, and it is not covered by guidelines for clinical practice. COPD and bronchiectasis share common symptoms of cough with sputum production and susceptibility to recurrent exacerbations driven by new or persistent infection. Physiological criteria for the diagnosis of COPD and structural criteria for the diagnosis of bronchiectasis create the possibility for individual patients to fulfil both, resulting conceptually in either co-diagnosis or an overlap syndrome between the two conditions. The prevalence of this overlap will vary depending on the respective prevalence of COPD and bronchiectasis in the population under consideration. A recent study of 201 COPD patients with airway wall abnormalities typical of bronchiectasis confirmed an association with exacerbations and was predictive of mortality over 48 months. A further, single-centre study demonstrated a near three-fold increased mortality rate, with patients with bronchiectasis and associated COPD having a 5-year mortality of 55%, compared with 20% in those with bronchiectasis without COPD. Airflow obstruction is perhaps best considered one marker of disease severity in bronchiectasis. Disease-associated exacerbations have a major effect on patient healthcare costs as well as quality of life due to increased lung damage and mortality risk. Microorganisms such as Pseudomonas aeruginosa and, to a lesser extent, other Gram-negative and Gram-positive microorganisms identified in culture, have been linked to disease progression, poor clinical outcomes in bronchiectasis and driving airway neutrophil-mediated inflammation. The microbiome has the potential to provide valuable information regarding disease phenotype/endotype, treatment responses and targets for future therapy.

This study is aiming at explore the characteristics of intestinal microbiome during the early progression of COPD, the correlation between the changes of intestinal microbiome and the severity and risk of acute exacerbation of COPD, the correlation between microbial metabolites SCFA and immune function of COPD. Then reveal the influence of intestinal microecology on the development of COPD and the possible mechanism of intestinal microecology in the pathogenesis of COPD.

Chronic Obstructive Pulmonary Disease (COPD) is the third leading cause of morbidity and disability with 251 million cases per anum reported worldwide. COPD ranks fourth among the common causes of mortality with an estimated 3 million annual deaths worldwide that is projected to be third by 2020. COPD deaths are more prevalent among the low socio-economic developing countries, estimated up to 90% of the total mortality rate across the globe. In Asia, 13.5% of the total population suffers with COPD. Particularly, in Pakistan every 10th individual suffers with COPD out of which 19.4% are of age above 40 years. Moreover, the problem has been identified as a growing public health concern and a challenge for the clinicians of 21st century. Consequently, the severity of the condition of patients is contributed by exacerbations or co-morbidities, and significant economic burden due to the hospitalizations, absence from work and disability; and its management cost from $1544 to $2335 in Asian countries, annually. However, specific data economic burden for Pakistan is not reported yet. A number of pharmaceutical and non-pharmaceutical treatment options are utilized in the management of COPD; however, pulmonary rehabilitation has been conferred as the corner stone in management of COPD. NICE guidelines emphasize upon the importance of pulmonary rehabilitation for all individuals presenting with COPD; even those who have acutely suffered an exacerbation or underwent recent hospitalization. Moreover, pulmonary rehabilitation consisting of structured exercises regimes and education regarding self-care has been reported to improve COPD symptoms and exercise tolerance; and reduce expenditure of resources on recurrent hospitalization and length of stay. Study has reported that resistance training demonstrated in better improvement in muscular strength than endurance exercise and causes lesser chances of dyspnea while performing activities and is more tolerable than endurance exercise regime. Literature is evident upon that the combination of resistance and endurance training has shown significant improvement in the respiratory parameters. Hence the present study is aimed to incorporate Proprioceptive Neuromuscular Facilitation (PNF) D2 pattern including different types of resistance training in order to determine the response of adjunct therapies on the outcome measures.

Background The Swiss health ministry launched a national quality program "QualiCCare" in 2011 to improve healthcare for patients with COPD. The aim of this study is to determine whether participation in the COPD quality initiative ("QualiCCare") improves adherence to recommended clinical processes and shows impact on patients COPD care and on quality of life in patients with COPD.

The goal of the study is to look at how genes and certain chemicals in the body are related to depression and chronic obstructive pulmonary disease.

Pulmonary rehabilitation of COPD patients are implemented in a non-randomized manner in two settings: primary and secondary health care. The effect on quality of life and hospitalizations will be evaluated

The aim of this study is to investigate the effects of changes in foot structure on physical activity level, fatigue and quality of life in COPD patients.
