Title: Subpopulations and Intermediate Outcome Measures in COPD Study
Brief Summary: SPIROMICS I and SPIROMICS II are observational studies of Chronic Obstructive Pulmonary Disease (COPD).

SPIROMICS I had two main aims: (1) To find groups of patients with COPD who share certain characteristics; (2) To find new ways of measuring whether or not COPD is getting worse and so provide new ways of testing whether a new treatment is working.

SPIROMICS II has three primary aims. Aim 1 is to define the natural history of "Smokers with symptoms despite preserved spirometry" and characterize the airway mucus abnormalities underlying this condition. Aim 2 is to determine the radiographic precursor lesion(s) for emphysema, and identify the molecular phenotypes underlying airway disease and emphysema. Aim 3 is to advance understanding of the biology of COPD exacerbations through analysis of predisposing baseline phenotypes, exacerbation triggers and host inflammatory response.


Options:
A: Inclusion Criteria:

* Between 40 and 80 at baseline visit
* Never smokers: \<1 pack-year history of smoking
* Never smokers: Must meet lung function criteria based on spirometry without inhaled bronchodilators
* Current or former smokers: \>20 pack-year history of smoking
* Current or former smokers: Must meet lung function criteria based on spirometry with inhaled bronchodilators

Exclusion Criteria:

* Dementia or other cognitive dysfunction which in the opinion of the investigator would prevent the participant from consenting to the study or completing study procedures
* Plans to leave the area in the next 3 years
* Smoking history of \> 1 pack-year but \<21 pack-years
* BMI \> 40 kg/m2 at baseline exam
* Prior significant difficulties with pulmonary function testing
* Hypersensitivity to or intolerance of albuterol sulfate or ipratropium bromide or propellants or excipients of the inhalers
* Non-COPD obstructive lung disease, severe kyphoscoliosis, neuromuscular weakness, or other conditions, including clinically significant cardiovascular and pulmonary disease, that, limit the interpretability of the pulmonary function measures.
* History of Interstitial lung disease
* History of Lung volume reduction surgery or lung resection
* History of lung or other organ transplant
* History of endobronchial valve therapy
* History of large thoracic metal implants (e.g., AICD (automatic implantable cardioverter/defibrillator) and/or pacemaker)

* Currently taking any immunosuppressive agent
* Current illicit substance abuse, excluding marijuana
* History of or current use of IV Ritalin

* Known HIV/AIDS infection
* History of lung cancer or any cancer that spread to multiple locations in the body
* History of or current exposure to chemotherapy or radiation treatments that, in the opinion of the investigator, limits the interpretability of the pulmonary function measures.
* Diagnosis of unstable cardiovascular disease including myocardial infarction in the past 6 weeks, uncontrolled congestive heart failure, or uncontrolled arrhythmia
* Any illness expected to cause mortality in the next 3 years
* Active pulmonary infection, including tuberculosis
* History of pulmonary embolism in the past 2 years
* Known diagnosis of primary bronchiectasis
* Currently institutionalized (e.g., prisons, long-term care facilities)
* Known to be a first degree relative of another, already enrolled participant (i.e., biological parent, biological sibling)
* Never smokers only: Current diagnosis of asthma
* Women only: Cannot be pregnant at baseline or plan to become pregnant during the course of the study
B: Inclusion Criteria:

* At least 10 pack-years of cigarette smoking (although a of nonsmoking controls is also being enrolled)
* Self-designation of non-Hispanic white or African-American

Exclusion Criteria:

* Other lung diseases (except for asthma in participants with COPD)
* Pregnant
* Cancer (other than skin cancer) in the 5 years prior to study entry
* Received antibiotics for a COPD exacerbation in the 1 month prior to study entry
* First- or second-degree relative of a previously enrolled study participant
C: Inclusion Criteria:

* Moderate or severe COPD with insufficiency of the ventilatory pump (according to GOLD stage IV). Stable disease since four weeks or more prior to randomisation. The COPD might be caused by whatever reason (smoking, Alpha-1 antitrypsin deficiency, ....). Smokers can be included.
* Capillary PCO2 of 7 kPa (51,8 mmHg) or maximally 10 kPa (74 mmHg), combined with a pH of 7.35 or above. These gases must be measured after 30 minutes breathing room air in sitting position. Patients on long term oxygen treatment must inhale oxygen in their prescribed dose.
* Only patients in the age of 18 years or above can be included.
* Written information about all aspects of the study (available in German language) must be provided for each patient. Written informed consent prior to any measure of this protocol is necessary for inclusion.

Exclusion Criteria:

* Patients with a PCO2 of 10 kPa (74 mmHg) or above. These patients can be re-evaluated for inclusion after 4 weeks.
* Diseases of the lung or thorax besides COPD: Advanced pulmonary fibrosis, advanced bronchiectases, active tuberculosis, post tuberculosis syndrome, pneumonia, severe kyphoscoliosis, tracheostoma, neuromuscular diseases, or any other disorder, which might result in elevated PCO2.
* Patients on NIV.
* Body mass index of 35 kg/m² or above.
* Severe cardiac disease, NYHA IV, instable angina, severe cardiac arrhythmia, especially of ventricular origin (atrial fibrillation is not an exclusion criterion).
* Malignoma
* Disorders of the basal brain nerves with derangement of swallowing, or reflexes of swallowing and choking.
* Local derangement of the face, skin, tongue, upper airways, larynx and upper oesophagus.
* Severe chronic diseases except COPD, hindering the patient to follow the schedule of this study.
D: Inclusion Criteria:

* An Institutional Review Board (IRB)/Independent Ethics Committee (IEC) approved written Informed Consent form is signed and dated by the subject. The Informed Consent form will be signed.
* Subject/legal representative is considered reliable and capable of adhering to the protocol (eg, able to understand and complete diaries), visit schedule or medication intake according to the judgment of the investigator.
* Subject with both genders is adult patients (\>18 years) diagnosed with bronchiectasis by high-resolution computed tomography (HRCT) of chest within 3 years of study inclusion having had at least 1 acute exacerbation in the previous year when recruiting.

Exclusion Criteria:

* History of cystic fibrosis;
* Hypogammaglobulinaemia;
* Allergic bronchopulmonary aspergillosis;
* Active tuberculosis;
