Mycobacterial Lung Diseases in Virginia: sequencing and clinical determinants of relapse and outcome

Shortness of breath (dyspnea) during exercise is a major source of distress and is a commonly reported symptom in patients with cystic fibrosis (CF). A recent drug treatment option known as Trikafta, which contains elexacaftor, tezacaftor, and ivacaftor, may be used in patients with CF to help improve lung health. However, the effects of this combination therapy on dyspnea and exercise performance, a known predictor of survival in CF, are not clear. The investigators aim to understand the effects of Trikafta on these symptoms and to gain new insight into the potential health improvements in CF from using this treatment option.

This study collects data on microbiological factors and lung function parameters (e.g. spirometry, body plethysmography, lung-MRI) to assess their interaction on the lung growth and lung development of infants and children with Cystic Fibrosis (CF).

Background Chronic Obstructive Pulmonary Disease (COPD) is an inflammatory disease of the lungs, which is most commonly caused by smoking. It is characterized as not fully reversible airflow limitation, chronic cough and dyspnoea. Being the fourth leading cause of death worldwide, COPD is an important public health challenge and can be prevented and treated. It is estimated that at least 400,000 individuals in Switzerland are affected by COPD. This number may increase in the coming years due to increasing nicotine consumption. In response to the rising trend, the Global Initiative for Chronic Obstructive Lung Disease (GOLD) has established new guidelines on the global strategy for diagnosis, management and prevention of COPD. Systematic diagnosis and stratification are crucial for effective treatment measures. As COPD is an irreversible and progressive disease, its treatment aims an early detection and better management, which leads preventing progression. Disease management programs have shown that only patients who understand their exacerbation symptoms can benefit. Moreover, it is a major goal to improve health-related quality of life by reducing symptoms and decelerating disease progression. Spirometry is the golden standard for the diagnosis of COPD, to assess the severity of the obstruction, and as a guide for optimal therapeutic measures. Aim of the study The objective of this project is to establish a COPD cohort database to allow high quality research on diagnosis, treatment, complication and progression of COPD on long-term course. Spirometry should be used consistently for the diagnosis and the monitoring of the development of the disease. Using collected information such as spirometric data, disease progression's data and therapeutic measures should help improve the management and self-management of the patients. Methods 3.1 Study design We are conducting a prospective cohort study, based on COPD patients from northern and western Switzerland, who are managed under primary care setting. Patients with mild to very severe COPD (GLOD stages I-IV) are enrolled in the study. Currently, 67 General practitioners (GPs) are participating in our Study. Each GP recruits 1-20 patients with presumed mild to very severe COPD according to criteria of the Global Initiative for Chronic Obstructive Lung disease [GOLD]. Patients' follow-up-visits occurs at 6-month intervals; their history, symptoms and examination status is recorded. Data is entered into an online database either by the physicians or by study team after receiving the collected data questionnaires by facsimile. Data collection includes demographic data, physical examination, spirometric parameters, medical treatment and exacerbation history besides death. A spirometer (EasyOne™, ndd Medizintechnik AG, Zürich, Switzerland) is used to assess lung function. All participating physicians were instructed on the usage of the spirometer and on how to complete spirometry according to the guidelines. For the assessment of the severity of COPD, we use the spirometric data provided by the GPs. The COPD severity is interpreted according to criteria of the GOLD committee. 3.2 Patient population Patients with newly diagnosed or existing COPD, who are managed in primary-care practices. 3.3 Inclusion criteria Tiffenau (FEV17FVC) < 70 without reversibility (Increase in FEV1 after inhalation of a bronchodilator <200 ml and <12%). Age: > 40 years Both genders Smokers or ex-smokers of at least 20 pack years. Informed consent. 3.4 Archiving and Data Retention All study-related records such as medical records, informed consent documents, information regarding participants who discontinued, and other pertinent data will be maintained and therefore retained as long as required by the applicable Swiss regulatory requirements (10 Years). 3.5 Data security The complete data of the study will be entered anonymously into a database. The data is password-protected and can only be accessed by investigators and study members. Publication and authorship 4.1 Publication policy Authorship credit is based on: Substantial contribution to conception and design, acquisition of data, or analysis and interpretation of data. Drafting the article or revising it critically for important intellectual content. Final approval of the version to be published. Each author should have participated sufficiently in the work to take public responsibility for appropriate portions of the content.

The purpose of this study is to further characterize early CF lung disease in newborns, infants and toddlers with cystic fibrosis (CF).

The purpose of the study is to evaluate the efficacy and safety of a biological vaccine (MV130 in subjects with Chronic Obstructive Pulmonary Disease (COPD) compared with a placebo group.

The London COPD exacerbation (EXCEL) cohort builds on an established cohort started in 1995 and designed to study COPD exacerbations and their impact on health-status and disease progression.

A complex interaction between demographic, environmental and genetic mechanisms impact the onset, severity and outcome of ILD-SARDs through dysregulation of the immune system and lung pro-biotic pathways. Comorbidity and genetic risk indicate that there are overlapping pathogenic mechanisms among SARDs, some of which underlie ILD in different SARDs. The purpose of this biobank is to study the clinical, pathological, laboratory, and imaging characteristics of SARDs patients with lung involvement. This will help identify as unique features underlying lung involvement in SARDs. In addition, this may lead to the discovery of novel mechanisms of disease and potentially novel targets of treatment for SARDs patients with lung disease.

This study aims to: Develop the BREATHE-ALD intervention for adults with Advanced Lung Disease, multiple chronic conditions, and palliative care needs and their caregivers using interviews with 10 advanced lung disease (ALD) adults and their caregivers To evaluate the feasibility and acceptability of intervention procedures; and To explore intervention effects on ALD outcomes

Chronic Obstructive Pulmonary Disease (COPD) is one of the top three causes of death worldwide now. Acute exacerbations (AEs) of COPD are a risk factor for lung function deterioration, poor quality of life, longer hospitalization, and increased mortality. To date, COPD is associated with a heavy clinical and socioeconomic burden, of which AEs of COPD account for a significant part of the cost of patients with COPD. Although several retrospective cohort studies and post-hoc analyses from randomized controlled trials (RCTs) showed that AECOPD patients with higher blood eosinophils had a shorter length of hospital stay (LOS), lower doses of corticosteroid use, and better response to systematic corticosteroid treatment than those with lower blood eosinophils, the efficacy of systematic corticosteroids in AECOPD patients with higher blood eosinophils has not been confirmed by RCTs. Therefore, this study aims to evaluate if AECOPD patients admitted to hospitals with higher blood eosinophil levels could benefit from systemic corticosteroid therapy. In this study, all eligible AECOPD participants with peripheral blood eosinophil blood count >2% or > 300 cells/μL will be randomly assigned (1:1) to either a control group or a systemic corticosteroid group. The control group will receive an oral placebo of 40mg/day for five consecutive days in addition to standard treatment during emergency admission or hospitalization. And systemic corticosteroid group will receive oral prednisone 40mg/day for five consecutive days and standard treatment. This study will provide evidence on using peripheral blood eosinophil blood count to guide corticosteroid therapy in AECOPD patients and help the clinician make an individual decision for each patient.
