Exposure to Aspergillus spores is associated with symptoms of asthma or airway inflammation (Chaudhary & Marr, 2011; Smith & Denning, 2011), leading to the possible onset of severe fungal complications with acute or chronic inflammation. In patients with chronic obstructive pulmonary disease (COPD), whose main etiological factor is cigarette smoke, A. fumigatus sensitization has been reported to be related to poor lung function (Bafadhel et al., 2014). Besides, COPD patients with fungal sensitization exhibit greater granulocyte count, implying more severe inflammation (Agarwal, Gaur, & Chowdhary, 2015). Fungal cultures from sputum are frequently positive in patients with asthma or with COPD (Pashley, 2014). Fungal colonization and infection have also been suspected to be related to exacerbations of COPD, but their potential role in the pathogenesis of COPD is poorly understood (Bafadhel et al., 2014). The hypothesis is that patients with COPD have a worsening of their pulmonary symptoms after exposure to fungal spores. This study will ensure the feasibility of quantifying environmental fungal exposure in patients' dwellings. For this, an electrostatic wipe will be deposited in the living room and another one in the bedroom for 12 weeks. The wipes will be analyzed by the mycology laboratory of the Croix Rousse hospital. If the results of this first study are conclusive, it is planned to continue this analysis with a regional multicentre study.
the study aims to investigate effectiveness of thoracic cage mobilizations on the chronic obstructive pulmonary diseases.
Recruitment of patients with COPD. Assessment of clinical status, determination of vitamin D and cathelicidin levels. In the group with vitamin D deficiency, patients receive cholecalciferol (vitamin D) daily for 3 months. After 3 months, the clinical status was assessed again, the level of vitamin D and cathelicidin was determined. When vitamin D levels normalize, cholecalciferol replacement therapy is discontinued for 3 months. After that, a control inspection and laboratory tests are performed.
Aim of investigators was to study whether abnormalities of lung diffusing capacity for nitric oxide (DLNO) and carbon monoxide (DLCO) in long COVID may have a clinical impact in relation to exercise intolerance.
The primary objective is to assess the relation between involuntary and voluntary assessed quadriceps muscle endurance in patients with COPD. We hypothesized a good correlation (>0.8) between the measurements.
Bronchoalveolar lavage (BAL) via flexible bronchoscopy is a method used to sample the cellular and microbiological components of the alveolar space. It is a procedure in which 2-3 measured aliquots of sterile normal saline are instilled after wedging the scope to the suitable segmental bronchus. BAL is performed from the segments/ lobes showing ground-glass opacities (GGO), tree-in-bud lesions or focal consolidations guided by HRCT. In diffuse lung involvement, BAL is performed either from RML or the lingula.[3] It is recovered through the bronchoscope via different suction methods so as to get a sample of epithelial lining fluid of small airways and alveoli. Either manual suction or wall suction can be used for aspiration of fluid during BAL. The fluid recovered is then sent for cytology and microbiology examination studies including AFB, MGIT, GeneXpert, Galactomannan, fungal cultures to diagnose various conditions like PAP, eosinophilic pneumonia, bacterial or fungal infections, specific forms of ILD. Three techniques have been described to perform BAL. To the best of our knowledge no previous study has compared the three methods of obtaining the BAL in the same cohort of subjects.The authors believe that the procedural yield of BAL will be best by manual suction using rubber tubing compared to manual suction without rubber tubing or wall suction. Herein, the investigators compare the three methods of obtaining BAL in subjects undergoing BAL for various respiratory diseases
Chronic obstructive pulmonary disease (COPD) patients with mucus hyper secretion tend to demonstrate increased frequency of infective exacerbations and a steeper slope of decline in lung function. Enhanced mucosal clearance with high frequency chest wall oscillation (HFCWO) devices previously used in cystic fibrosis and bronchiectasis patients may offer the opportunity for community based, self-managed therapy to improve quality of life and lung function. The aim of this study is to compare effects of active cycle of breathing and high frequency chest wall oscillations in chronic obstructive pulmonary disease .This study will be a Randomized Clinical trial and will be conducted at Physical Therapy Department of DHQ Hospital NAROWAL. The study will be completed within the time duration of six months. Consecutive sampling technique will be used to collect the data. A sample size of Total 42 patients will be taken in this study. Patients will be divided into two groups. BODE Index will be used as outcome measurement tool. Group A will receive the Active cycle of breathing technique and it will performed twice a day for 4 week intervention period for 20 minutes. Group B will receive high frequency chest wall oscillations at 13-15Hz oscillating frequency for 20 minutes twice a day for 4 weeks. The collected data will be analyzed on SPSS - 25.
Background: Non-invasive ventilation (NIV) reduces respiratory load and demands on peripheral muscles. Methods: This study aims to evaluate the acute effects of bi-level NIV on peripheral muscle function during isokinetic exercise and aerobic performance in chronic obstructive pulmonary disease (COPD) patients. This is a pilot crossover study performed with a non-probabilistic sample of 14 moderate to very severe COPD patients. Procedures carried out in two days. Dyspnea, quality of life, lung function, respiratory muscle strength, functional capacity (6-minute walk test - 6MWT), and isokinetic assessment of the quadriceps were assessed. Blood samples (lactate, lactate dehydrogenase, and creatine kinase concentration) were also collected. Right after, NIV was performed for 30 minutes (bi-level or placebo, according to randomization) followed by new blood sample collection, 6MWT, and isokinetic dynamometer tests. Before and after evaluations, the subjective perception of dyspnea and fatigue in the lower limbs was quantified. After a wash-out period of seven days, participants returned, and all assessments were performed again.
This research is being done to evaluate the feasibility, and biopsy quality, of using a 1.1mm disposable cryoprobe that is passed through the working channel of the Ion Robotic bronchoscope to collect biopsy tissue.
