Microbiology & Immunology of the Chronically-inflamed Airway (RESP RES-001 (117027))

Chronic obstructive pulmonary disease (COPD) is the fourth most common cause of death and the only one of the common causes that is still rising. The main effects of the disease are the destruction and inflammation of lung tissue rendering breathing difficult. COPD has significant effects on the quality of life of sufferers and the disease is predicted to be the fifth most common cause of disability in the world by 2020. Patients with COPD are prone to periods of worsening disease symptoms, known as exacerbations, which are often caused by viral and bacterial infections of the lung and current vaccines appear to have little efficacy in limiting these exacerbations. The loss of lung function caused by infectious exacerbations is irreversible and patients who frequently exacerbate experience more rapid disease progression. Nontypeable Haemophilus influenzae (NTHi) is a major bacterial species that colonises the airways and causes exacerbations in COPD. With the development of more sensitive molecular techniques it has been possible to ascertain that it is the acquisition of new strains of NTHi that correlate strongly with exacerbations. However, not all patients with COPD have NTHi in their lungs and the question remains as to why some COPD patients are susceptible to such infections. This study aims to answer this question by comparing the airways of COPD patients who are colonized by NTHi and those who are not to analyse whether the levels of protective antibodies in the lungs and the function of the immune cells in the NTHi colonized airway are reduced. Moreover, we aim to correlate this reduction in immunity with areas of lung damage ascertained by high resolution computed tomography. The aim of this research is to better understand this apparent deficiency in airway immunity as this is likely to impact on vaccine efficacy in COPD.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

40 years to 85 years (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Volunteers will be recruited from General Practice in the form of patient screening clinics,and GP Mailshot. Quitters and pulmonary rehabilitation, would also be approached. The Respiratory Centre, patient support groups, and outpatient departments and wards, would also be areas of recruitment.

Description

Inclusion Criteria:

  • Subjects who the investigator believes can and will comply with the requirements of the protocol.
  • Written informed consent obtained from the subject.
  • Male or female subjects between, and including, 40 and 85 years of age, at the time of consent.
  • Subjects with confirmed diagnosis of COPD (based on postbronchodilator spirometry). [GOLD, 2009] with FEV1 of >80% (mild COPD) or >50% but ≤80% (moderate COPD) of predicted normal and FEV1/FVC<0.7
  • Subjects have mild or moderate COPD, according to Global Initiative for Chronic Obstructive Lung Disease (GOLD) staging [GOLD, 2009].
  • Subjects have a current or prior history of ≥10 pack years of cigarette smoking. Former smokers are defined as those who have stopped smoking for at least 6 months. Number of pack years = (number of cigarettes per day/20) x number of years smoked.
  • Subjects with recent COPD exacerbations, in stable condition, and having stopped antibiotics, can be enrolled one month post exacerbation.

Exclusion Criteria:

  • Subject also has a confirmed diagnosis of asthma (as only cause of obstructive respiratory disorder), cystic fibrosis, pneumonia risk factors (e.g., HIV, Lupus, Parkinson's, Myasthenia Gravis) or other respiratory disorders (e.g., tuberculosis, lung cancer).
  • Subjects having undergone lung surgery
  • Subject has a α1-antitrypsin deficiency as underlying cause of COPD.
  • Subject who experienced a moderate or severe COPD exacerbation not resolved at least 1 month prior to enrolment visit and at least 30 days following the last dose of oral corticosteroids (subjects can be enrolled when their acute AECOPD or pneumonia has resolved).
  • Subject using any antibacterial, antiviral or respiratory investigational drug or relevant vaccine up to 30 days prior to the enrolment visit.
  • Subject has other conditions that the principal investigator judges may interfere with the study findings, such as:
  • Subject at risk of noncompliance, or unable to comply with the study procedures.
  • Evidence of alcohol or drug abuse.
  • Others, as per clinical judgement
  • Women who are pregnant or lactating or are planning on becoming pregnant during the study **If subject has any ONE of the above exclusion they cannot be enrolled into the study**

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Detection of NTHi in radiologically-designated areas of disease in the COPD lung
Time Frame: Within 2 years of enrollment
The overall aim of this project is to enhance our understanding of the relevance of local immunity to protection of the airway from viral and bacterial infection and thus development of vaccines against such organisms.
